Description

Technical Field:

[0001] The utility model relates to the technical field of roadway equipment movement, specifically to a crawler equipment multiple unit. Background Art:

[0002] The mechanized fully-mechanized coal shearer is an important equipment for coal mining. As the working face is mined and advanced, auxiliary equipment such as transformers, hydraulic pump stations, cable liquid pipes that provide power for the mechanized fully-mechanized coal shearer need to be pulled forward every 3 - 5 days to keep a certain distance from the coal shearer. Patent 202110332340.4 discloses a mine roadway slide rail multiple unit, which mainly includes structures such as slide rails, deviation adjustment and guiding devices, cable drag chain car groups, and flatbed trucks; its main innovation lies in that rollers, pulleys, and supporting wheels can both walk and suspend the slide rails. When the train moves, the rollers and supporting wheels support the entire vertical vehicle to walk; when pushing the slide rails forward, the whole equipment is lifted upward through a lifting device, and the rollers, pulleys, and supporting wheels can suspend the slide rails away from the ground, and then the slide rails are pushed forward through a power oil cylinder to complete the moving process. When the flatbed truck and the cable drag chain car group move forward with the coal shearer, the slide rails are in contact with the roadway ground. However, due to the uneven roadway ground, the contact degree between the slide rails and the roadway ground is poor, resulting in poor stability of the slide rails and equipment such as the flatbed truck and cable trailer on them; and the moving distance at one time is short, the track needs to be moved frequently, and the operation is cumbersome. Content of the Utility Model:

[0020] At the top of the slide rail 1 at the front end of several cable drag chain vehicle groups 3, a head flatbed truck 9 is provided. The structure of the head flatbed truck 9 is the same as that of the flatbed truck 4. On the truck bed 41 of the head flatbed truck 9, a bridge 10 connected to the tail of the shearer is provided; the truck bed 41 of the head flatbed truck 9 is connected to the running chassis 31 of the adjacent cable drag chain vehicle group 3 through a towing bar 5.

[0021] The slide rail 1 in this embodiment is a crawler-type slide rail. The crawler-type slide rail includes a crawler 11 and a channel rail 13. On both sides of the crawler plate 14 of the crawler 11, a channel rail 13 with a notch facing outward is respectively fixed. The rollers 32 at the bottom of the cable drag chain vehicle group 3, the load-bearing wheels 42 at the bottom of the flatbed truck 4, and the pulleys 22 at the bottom of the deviation adjusting and guiding device 2 are all rollingly arranged in the corresponding channel rails 13 on both sides. By arranging the channel rails 13 on both sides of the crawler 11, when it is necessary to push the slide rail 1 forward, the crawler-type slide rail can be lifted upward as a whole through the cooperation of the rollers 32, the load-bearing wheels 42, and the pulleys 22 with the channel rails 13, so that it is separated from the ground, facilitating the cable winding mechanism 6 to wind up the crawler-type slide rail.

[0022] When the channel rail 13 is a channel steel, the movement of the equipment can be realized by the rollers 32, the load-bearing wheels 42, and the pulleys 22 rolling along the channel rail 13; or as shown in this embodiment, the channel steel 13 is an inverted L-shaped angle steel, and walking wheels 8 walking along the chain track 15 on the crawler 11 of the crawler-type slide rail are rotatably provided at the bottom of the trolley 21 of the deviation adjusting and guiding device 2, at the bottom of the running chassis 31 of the cable drag chain vehicle group 3, and at the bottom of the truck bed 41 of the flatbed truck 4. When it is necessary to move the equipment forward, the deviation adjusting and guiding device 2, the cable drag chain vehicle group 3, and the flatbed truck 4 walk along the crawler 11 through the walking wheels 8 at their bottoms.

[0023] A cable winding mechanism 6 for winding and unwinding the crawler-type slide rail is respectively provided on the deviation adjusting and guiding device 2 and the head flatbed truck 9; the cable winding mechanism 6 includes a guide wheel 61, a frame 62, a driving shaft 63, a sprocket 64, and a winding and unwinding drive 65. The frame 62 is fixed on the top of the trolley 21 of the corresponding deviation adjusting and guiding device 2 or the truck bed 41 of the head flatbed truck 9. At the top of the frame 62, a driving shaft 63 perpendicular to the moving direction of the crawler-type slide rail is rotatably provided. On the frame 62, a winding and unwinding drive 65 for driving the driving shaft 63 to rotate is provided; a sprocket 64 is rotatably provided on the driving shaft 63, and the sprocket 64 meshes with the crawler 11; a guide wheel 61 is rotatably provided at the outer end of the frame 62, and the guide wheel 61 matches the chain track 15 on the crawler 11 of the crawler-type slide rail; both ends of the crawler-type slide rail respectively bypass the guide wheels 61 of the cable winding mechanisms 6 at both ends and are fixed to the corresponding sprockets 64. In this embodiment, the winding and unwinding drive 65 is a motor with an output shaft drivingly connected to the driving shaft 63. By driving the driving shaft 63 to rotate forward and backward through the winding and unwinding drive 65, the sprocket 64 can be driven to rotate forward and backward, realizing the winding and unwinding of the crawler-type slide rail.

The fixed seat 71 is fixed to the end of the corresponding trolley 21 or vehicle board 41. One end of the rocker arm 72 is hinged to the outer end of the fixed seat 71. A drive sprocket 75 is rotatably provided at the other end of the rocker arm 72. A traveling drive 74 for driving the drive sprocket 75 to rotate is fixed on the rocker arm 72.

In this embodiment, the driver 7 is installed at the rear end of the middle flatbed truck 4. The lifting oil cylinder 73 is hinged between the middle of the rocker arm 72 and the fixed seat 71 above it. The traveling drive 74 is a drive motor, and its output shaft is in transmission with the rotating shaft of the drive sprocket 75. When the piston rod of the lifting oil cylinder 73 is controlled to extend, the other end of the rocker arm 72 can be driven to swing downward, thereby driving the drive sprocket 75 to move downward to mesh with the crawler 11. Then, when the traveling drive 74 is started, the drive sprocket 75 can be driven to travel along the crawler 11, thereby driving the flatbed truck 4 and the deviation-adjusting guiding device 2 as a whole to move along the crawler-type slide rail. When the crawler-type slide rail needs to be moved, the piston rod of the lifting oil cylinder 73 is controlled to retract, and the other end of the rocker arm 72 is driven to swing upward, so as to drive the drive sprocket 75 to disengage from the crawler-type slide rail.

The specific operation process is as follows:

[0032] First, control the piston rod of the lifting oil cylinder 73 to retract so that the driving sprocket 75 is disengaged from the crawler 1;

[0033] Then, control the pulley 22, the roller 32 and the idler wheel 42 to move upward to lift the trough rail 13 and the crawler 11 as a whole upward until it is disengaged from the ground;

[0034] Next, control the rear-end chain winding mechanism 6 to start releasing the belt, and the front-end chain winding mechanism 6 to start winding the belt until all the vacated crawler-type slide rails are wound on the sprocket 64 of the front-end chain winding mechanism 6;

[0035] Finally, control the pulley 22, the roller 32 and the idler wheel 42 to move downward to lower the trough rail 13 and the crawler 11 as a whole to the ground, and then the machine can be stopped.

[0036] Repeating the above (2) and (3) can realize the random movement of the equipment.
