SQ series stepless rope continuous towing vehicle

The endless rope haulage vehicle absorbs and draws on some of the excellent technologies of rope haulage rail cars, and refers to the use experience of traditional endless rope haulage vehicles, creatively developing a kind of practical new auxiliary transportation equipment. This is a further improvement and perfection of the underground endless rope auxiliary transportation system, and has the following characteristics:

1. High reliability. The winch adopts a mechanical transmission method.

2. Industrial control display, button control, centralized signal control, convenient operation. It greatly improves the operability and visibility for workers, reducing the physical exertion of the operator.

3. Flexible system layout. The winch can be arranged along the track, parallel to the track, or perpendicular to the track. Two-way transportation, it can also be arranged as a three-track (three tracks) two-way transportation. Steel wire ropes can be used in the same track; or the main rope can be in the track, while the auxiliary rope is outside the track.

4. Strong adaptability and wide application. The endless rope haulage vehicle can be used in both inclined shafts and in the up (down) mountain areas of mining areas. It can also be arranged in centralized track lanes, as well as auxiliary inclined shafts and supporting services after excavation.

5. Convenient configuration and simple installation. Using rope pressing, rope supporting and horizontal bends, etc., with strong rope pressing ability and small turning radius, it can adapt to the transportation needs of undulating slopes and horizontal turns. Flexible fixing, convenient disassembly and movement.

Main components

SQ series endless rope continuous haulage vehicles generally include winches, tensioning devices, shuttles, tail wheels, rope pressing wheel sets, rope supporting wheel sets and matching electrical controls, forming a transportation system through steel wire ropes.

Winch main unit

The winch is the power source of the entire system and comes in various forms.

According to the speed regulation method, it is divided into: mechanical speed regulation, frequency conversion speed regulation, and switched reluctance speed regulation; according to the friction wheel, it is divided into parabolic single-drum structure and rope groove double-drum structure. It is mainly composed of motor, base, reducer, drum part, coupling, electro-hydraulic brake, manual brake, etc. The driving drum and rope diameter ratio are more than 50 times, meeting the requirements of MT/998-2006 standard.

Tensioning device

It can absorb the part of the steel wire rope system that is elongated due to elastic deformation, and at the same time, it can provide tension for the winch to ensure that the steel wire rope has a relatively stable positive pressure on the rope lining of the winding drum. The tensioning device is divided into three-wheel and five-wheel types, selected according to the slope size and the length of the roadway.

Shuttle

The shuttle is used to connect trains of mine cars, flat cars, material cars, etc., and has the functions of rope breaking protection and fixing and storing steel wire ropes. The front and rear ends are head-to-head, connecting the trains. The shuttle is mainly composed of the following parts: frame, rope storage drum, wheel assembly, etc. Shuttles have two specifications: 600mm and 900mm gauge, including normal light shuttles, heavy-duty shuttles, eight-wheel turntable shuttles, and hydraulic track-hugging shuttles.

Tail wheel or return rope station

The tail wheel or return rope station is fixed at the end of the transportation distance, supporting the reaction force of the entire system, and also playing a fixing role for the steel wire rope. It can be easily moved with the advancement of the working face to achieve changes in the transportation distance. When transporting supports, a cement foundation must be poured to fix the tail wheel; in other cases, anchor rods or other methods can be used to fix the tail wheel. Tail wheels are divided into single tail wheels, double tail wheels, large tail wheels, and through tail wheels, depending on user requirements and specific roadway conditions.

Wheel set

To adapt to undulating slopes, wheel sets are arranged along the way, which can prevent vehicles from derailing when the steel wire rope is lifted, and can also avoid the steel wire rope from rubbing against the roadway bottom plate. This includes main rope pressing wheel sets, auxiliary rope pressing wheel sets, rope supporting wheel sets, and crossing wheel sets. The main rope pressing has two or three wheels; using tension springs or compression springs. According to the rope arrangement method, it is also divided into: single wheel set and combined wheel set.

Bending device (required when turning)

If the roadway needs to turn, a specially designed bending guardrail system or turning wheel set, etc., must be configured. The number used can be determined by calculating the turning radius of the track when the roadway turns.

Electrical control protection system

Equipped with a leakage mobile communication/signal system or an inorganic rope winch integrated protection device. The former has functions such as point marking, communication, and emergency stop; the latter uses an imported high-speed programmable logic controller (PLC) as the core, equipped with a professional human-machine interface, with real-time monitoring, speed display, emergency stop, over-winding, under-winding, overspeed, underspeed, and other protection functions, and has functions such as shunt voice warning and roadside voice communication. It is used in conjunction with the endless rope winch electrical control switch to achieve automated control of the winch.

The endless rope frequency conversion control system can realize the start and stop control, forward and reverse running control, speed adjustment control, manual and automatic running control of the endless rope haulage winch; realize the control of the brake's lifting and lowering; and realize the integration of all controls on the same operating panel. The operating panel is equipped with a 10.4-inch color LCD screen, displaying the system running status and fault status, mainly including current and voltage display, speed and shuttle running position display, etc. The monitoring screen has a roadway schematic diagram (with special sections such as slope change points, junctions, and bends). The system has the function of real-time detection and control of the endless rope haulage winch; automatic reset and zeroing after each operation, eliminating accumulated errors, and requiring the ability to modify according to different on-site conditions. Using four-item limit operation, it has a 100% energy feedback function; overload capacity 200%; has anti-interference ability to other electrical equipment underground; and the protection functions for the load and the frequency converter itself are complete, such as: overcurrent, over/undervoltage, power/load phase loss, overload, instantaneous power failure, short circuit, etc.
