[0002] Currently, most of the transport vehicles used in mines are traditional rail-mounted winches with steel wire rope traction. When moving, the train set is prone to slippage, the steel wire rope is very easy to break, causing runaway trains and accidents. The overall stability is poor, the transportation is difficult, the labor intensity is high, and the safety factor is low. This is a recognized challenge for coal mining enterprises at home and abroad. Summary of the Invention

[0003] To solve the transportation problem of equipment in underground coal mine roadways, this invention provides a new type of heavy-duty electrically controlled mobile transport vehicle for auxiliary roadways in mines.

[0004] The present invention adopts the following technical solution: a new type of heavy-duty electrically controlled mobile transport vehicle for auxiliary roadways in mines, comprising a head traction device, a heavy-duty vehicle and a large-capacity rope telescopic mechanism, wherein the head traction mechanism is connected to the heavy-duty vehicle, and the heavy-duty vehicle is connected to the large-capacity rope telescopic mechanism through a connecting rod.

[0005] The head traction mechanism includes a head traction device and a head pushing device, which are connected by a pushing cylinder. The heavy-duty vehicle includes several heavy-duty rail lifting cars and several heavy-duty rubber-tired flatbed cars. The heavy-duty rail lifting cars are connected by a flatbed car connecting plate, and the heavy-duty rubber-tired flatbed cars are connected by a connecting plate. The heads of the heavy-duty rail lifting cars are connected to the head pushing device, and the tails of the heavy-duty rail lifting cars are connected to the heads of the heavy-duty rubber-tired flatbed cars. The tails of the heavy-duty rubber-tired flatbed cars are connected to the large-capacity rope telescopic mechanism. The large-capacity rope telescopic mechanism includes a winch carrier car and a cable carrier car. One end of the winch carrier car is connected to a connecting rod, and the other end is connected to the cable carrier car. Several sets of cable carrier cars are provided, and the cable carrier cars are interconnected. The cable carrier cars at the tail end are equipped with a support pushing rod.

[0006] Furthermore, the head traction device includes a head support mechanism, columns, diagonal brace cylinders, a tilting mechanism, and a crossbeam. Two columns are provided, with the bottom of the columns hinged to the head support mechanism and the top of the columns hinged to the crossbeam. The two columns are connected by clamps, and a diagonal brace cylinder is connected between the clamps and the head support mechanism. A tilting mechanism is installed at each end of the head support mechanism. The tilting mechanism includes a tilting base, and two tilting cylinders are fixed in the middle of the tilting base. The outer ends of the tilting cylinders are hinged to the bottom of the lifting cylinder. The lifting cylinder is vertically set, and the top of the lifting cylinder is connected to the head support mechanism.

[0007] Furthermore, the head-moving device includes a head-moving device base, two support columns and column top covers, with the column top covers hinged to the two support columns and the bottoms of the two support columns mounted on the head-moving device base.

[0008] Furthermore, the winch carrier includes a support base with two supporting columns. A small top beam for supporting the top plate is installed on the two columns. A return winch is set in the middle of the support base. The return winch pulls the cable carrier through a steel wire rope. The front of the support base is connected to the heavy-duty vehicle through a connecting rod, and the rear of the support base is connected to the cable carrier through a telescopic pneumatic cylinder.

[0009] Furthermore, the cable carrier vehicle includes a cable carrier frame, a cable carrier support, a support rod, and a telescopic pneumatic cylinder. The cable carrier frame is equipped with a support rod consisting of two sleeves connected by a pin. The cable carrier support is attached to the support rod. The cable carrier support is a rod-like structure consisting of several sections that are hinged to each other. A telescopic pneumatic cylinder is installed at the end of the cable carrier frame. Two adjacent cable carrier vehicles are connected by the telescopic pneumatic cylinder, and the cable carrier supports on two adjacent cable carrier vehicles are hinged to each other.

[0010] Furthermore, the cable support frame includes several segmented connecting rods, the ends of adjacent connecting rods are hinged through a supporting round steel pipe, the upper side of the supporting round steel pipe carries the cable, and the cable is fixed by fixing blocks on the upper and lower sides respectively, and the fixing blocks on both sides are fixedly connected by screws.

[0011] The working process of the transport vehicle assembly of this invention is as follows: The supporting column of the head-mounted pushing device and the two columns of the winch-carrying vehicle rise to support the top plate and form a stable anchoring point. At the same time, the lifting cylinder on the heavy-duty vehicle rises, and the rail is lifted. At this time, the piston rod of the pushing cylinder extends, moving the head-mounted traction device and the rail forward by one step. The supporting column of the head-mounted pushing device and the two columns of the winch-carrying vehicle lower, and at the same time, the lifting cylinder on the heavy-duty vehicle lowers, the rail lands, and the two columns on the head-mounted traction device rise, with the crossbeam supporting the top plate to form a stable anchoring point. At this time, the pushing cylinder retracts, pulling the heavy-duty rail lifting vehicle, the heavy-duty rubber-tired flatbed vehicle, and the entire set of large-capacity cable telescopic mechanism forward, completing one step forward, thus completing one step cycle of the entire equipment. The winch wire rope assists in traction of the cable-carrying vehicle, ensuring that the cable-carrying vehicle will not slip on sloping roadways.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention has significant advantages, equipped with a dedicated track, and is integrated with the heavy-duty rail lifting car via lifting pins. The pressure roller is hinged to the heavy-duty rail lifting car via a pin shaft, rolling forward on the track. It has functions such as self-movement, anti-runaway, anti-derailment, and anti-slipping. The head traction device and the heavy-duty rail lifting car are equipped with adjustment cylinders, which can realize walking and adjustment, saving labor. The heavy-duty rubber-wheeled flatbed car has a simple structure, saves costs, reduces noise, and is easy to turn. The return winch assists in pulling the cable carrier car, preventing slippage caused by the advance support pushing the cable carrier car. Attached Figure Description

[0026] The new type of heavy-duty electrically controlled mobile transport vehicle for mine auxiliary roadways consists of three parts: a head traction mechanism, a heavy-duty vehicle, and a large-capacity telescopic rope mechanism. The head traction mechanism includes a head traction device 1 and a head pushing device 3, which are connected by a pushing cylinder 2. The heavy-duty vehicle is divided into a heavy-duty rail hoisting vehicle 4 and a heavy-duty rubber-tired flatbed vehicle 5. The heavy-duty rail hoisting vehicle 4 has its own rails, a large load capacity, and graphite self-lubricating rollers. The heavy-duty rubber-tired flatbed vehicle 5 is low-cost, low-noise, and easy to turn underground. The high-capacity cable telescopic mechanism includes a winch carrier 6 and a cable carrier 8. The winch carrier has a return winch 20 for assisting in pulling the cable carrier, and two support columns 21 for supporting. The rear cable carrier is equipped with a support push rod 9, which is connected to the advance support. When the advance support moves forward, it compresses the telescopic pneumatic cylinder 25, thereby compressing the cable carrier 8 and shrinking the cable. The high-capacity cable telescopic mechanism can carry 20 cables at the same time and can compress a 150m cable to about 70m.

[0027] The head traction device 1 includes a head support mechanism 10, uprights 11, diagonal brace cylinders 12, an adjustment mechanism 13, and a crossbeam 14. The two ends of the uprights are connected to the head support mechanism 10 and the crossbeam 14, respectively. The two uprights are connected by clamps, and a diagonal brace cylinder 12 connects the clamps to the head support mechanism. The diagonal brace cylinder 12 adjusts the angle of the head traction device 1, achieving synchronous limiting of the two uprights 11. An adjustment mechanism 13 is installed at each end of the head support mechanism 10. The adjustment cylinder 27 and the bottom-lifting cylinder 26 actuate to achieve the adjustment action of the head traction device 1.

[0028] The heavy-duty rail lift car 4 rides on the rail. Its structure consists of two parts: the heavy-duty rail lift car frame 15 and the lifting cylinders 16. Each heavy-duty rail lift car is equipped with four lifting cylinders 16. The lifting cylinders 16 operate simultaneously to complete the lifting and lowering of the heavy-duty rail lift car 4.

[0029] The heavy-duty rubber-tired flatbed cart 5 consists of two parts: a heavy-duty rubber-tired flatbed cart frame 17 and wheels 18. Each heavy-duty rubber-tired flatbed cart 5 is equipped with two sets of wheels 18, and the wheels are made of solid tires to adapt to the harsh underground environment. The heavy-duty carts are connected by connecting plates.

[0030] The main structure of the heavy-duty rail hoisting car includes a heavy-duty rail hoisting frame 15, hoisting cylinders, a base plate assembly 36, pressure rollers 30, and hoisting pins 31. The bottom sides of the heavy-duty rail hoisting frame 15 are connected to the base plate assembly 36 via hoisting cylinders, and the bottom of the heavy-duty rail hoisting frame 15 is connected to the pressure rollers 30 via hoisting pins 31. Channel steel is welded to the bottom of the heavy-duty rail hoisting frame 15 to enhance its strength and allow passage of hoses, etc. When the hoisting cylinders extend, the base plate assembly presses against the ground, lifting the rail. The pushing cylinders extend, and the head traction device moves the rail forward one step. The side pushing cylinders actuate, pressing against the side of the roadway to adjust the equipment's alignment. With a load capacity of up to 40t, the heavy-duty rail lifting vehicles are hinged together by a flatbed connecting plate. The heavy-duty rubber-tired flatbed vehicle includes a heavy-duty rubber-tired flatbed frame and two sets of wheels. Channel steel is welded to the bottom of the heavy-duty rubber-tired flatbed frame to enhance the strength of the heavy-duty rail lifting vehicle frame and allow rubber pipes to pass through. The heavy-duty rubber-tired flatbed vehicles are hinged together with the heavy-duty rail lifting vehicles by a flatbed connecting plate, and the heavy-duty rubber-tired flatbed vehicles are also hinged together by a flatbed connecting plate. The wheels are solid tires, with a load capacity of up to 30t.

[0031] The winch carrier 6 is part of the large-capacity telescopic mechanism and is used between the large-capacity telescopic mechanism and the heavy-duty car. The winch carrier 6 includes a support base 19, a return-column winch 20, and two support columns 21. A small top beam is installed on the two columns 21 to support the top plate and increase the contact area. The winch carrier 6 is connected to the heavy-duty car via a connecting rod 7, and its rear is connected to the cable carrier 8 via a telescopic pneumatic cylinder 25. The return-column winch 20 is installed on the support base 19, and the wire rope pulls the cable carrier 8, ensuring that the cable carrier 8 will not slip on sloping roadways.

[0032] The cable carrier 8 is used to carry cables underground and includes a cable carrier frame 23, a cable carrier rack 22, a support rod 24, and a telescopic pneumatic cylinder 25. The support rod 24 consists of two sleeves connected by a pin and is fixed to the cable carrier frame 23; its height is adjustable. The cable carrier rack 22 overlaps the support rod 24 and is secured with bolts. The cable carrier rack 22 can simultaneously lay 20 cables and is then secured to the cable carrier rack 22 by a connecting plate and bolts. The cable carriers 8 are connected by telescopic pneumatic cylinders 25; the retraction and extension of the cylinders allow the cable carriers 8 to retract and open.

[0033] The cable support frame 22 includes several segmented support connecting rods 39. The ends of adjacent support connecting rods 39 are hinged through support round steel pipes 37. The support round steel pipes 37 support cables 41 on the upper side. The cables 41 are fixed by fixing blocks 40 on the upper and lower sides respectively. The fixing blocks 40 on both sides are fixedly connected by screws 38.

[0034] The working process of the transport vehicle group of the present invention is as follows: The supporting column 30 of the head pushing device 3 and the two supporting columns 21 of the winch carrying vehicle 6 are raised to support the top plate and form a stable anchoring point. At the same time, the lifting cylinder 16 on the heavy-duty vehicle is raised, and the rail is lifted. At this time, the piston rod of the pushing cylinder 2 extends, moving the head traction device 1 and the rail forward by one step. The supporting column 30 of the head pushing device 3 and the two supporting columns 21 of the winch carrying vehicle 6 are lowered. At the same time, the lifting cylinder 16 on the heavy-duty vehicle is lowered, the rail is placed on the ground, and the two columns 11 on the head traction device 1 are raised. The crossbeam supports the top plate and forms a stable anchoring point. At this time, the pushing cylinder 2 retracts, pulling the heavy-duty rail lifting vehicle 4, the heavy-duty rubber-wheeled flatbed vehicle 5, and the entire set of large-capacity cable telescopic mechanism forward to complete one step forward movement, thereby completing one step cycle of the entire set of equipment. The return column winch 20 assists in traction of the cable carrying vehicle 8 to ensure that the cable carrying vehicle 8 will not slip on the sloping roadway.

[0035] The working process of the large-capacity telescopic mechanism of the present invention is as follows: The two supporting columns 21 of the winch carrier 6 are lowered, the piston rod of the push cylinder 2 is retracted, driving the heavy-duty cars 4 and 5 and the large-capacity telescopic mechanism to move forward. The telescopic pneumatic cylinder 25 is connected to the winch carrier 6 through a pin shaft. At this time, the piston rods of all telescopic pneumatic cylinders 25 are extended, and the cable carrier 8 of the large-capacity telescopic mechanism is pulled open, which is in the process of releasing the cable. The left side of the support push rod 9 is connected to the advance support. The advance support is activated, pushing the cable carrier 8 forward. At this time, the outer cylinder of the telescopic pneumatic cylinder 25 also moves forward. The telescopic pneumatic cylinder 25 is retracted, the cable carrier 8 is retracted, and the cable is in the process of being retracted. The wire rope of the return winch 20 is fixed to the last cable carrier 8. When the return winch 20 is working, it pulls the cable carrier 8 forward. At this time, the outer cylinder of the telescopic pneumatic cylinder 25 also moves forward. The telescopic pneumatic cylinder 25 retracts, the cable carrier 8 is retracted, and the cable is in the process of being retracted.
