Description

Technical Field

[0001] The utility model belongs to the technical field of monorail crane locomotives, in particular to a lithium-electric powered monorail crane locomotive for mining. Background Art

[0002] Monorail locomotive is a specially designed transport equipment, mainly used for heavy object handling in mines, tunnels, warehouses and other limited spaces or under specific track conditions. Unlike the traditional double-track railway system, it only needs one track to operate, so it is particularly useful in space-constrained environments.

[0003] The existing lithium-powered monorail crane for mining uses a motor to drive the running wheels to rotate to move the crane on the track, and then uses the cooperation of springs and friction blocks to brake the crane when it stops through the friction between the friction blocks and the track. However, in actual use, the rebound force of the spring will decrease after a certain period of use, thereby reducing the braking effect of the crane. When the crane stops, it may continue to move a short distance due to inertia, and the position of the crane cannot be well controlled. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides a lithium-powered monorail crane for mining. When the crane needs to be stopped, the traveling wheels are controlled to stop rotating quickly while the brake blocks are quickly close to the track, thereby effectively ensuring the position of the crane and achieving rapid and stable braking, thereby accurately controlling the position of the crane.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a lithium-powered monorail crane locomotive for mining, comprising a moving seat, the lower surface of the moving seat is provided with two hangers symmetrically distributed on the left and right, movable arms are slidably provided on the left and right sides of the moving seat, and drive boxes are provided on the upper sides of the movable arms, and two support rods symmetrically distributed front and back are provided on the opposite inner sides of the two drive boxes, and a rotating seat is provided on one side of the four support rods close to the vertical center of the drive box, and running wheels are rotatably provided inside the rotating seat through a rotating shaft, and brake blocks are provided on one side of the four rotating seats close to the vertical center of the drive box, and an electric control module for driving the rotating seat to move is also provided on the moving seat, and an electric drive module for driving the running wheels to rotate is also provided on the drive box; rubber pads are bonded and fixed on both sides of the upper surface of the hanger.

[0006] As a further improvement of the present invention, the electric drive module includes a rotating shaft rotatably arranged on the front and rear sides of each drive box, the rotating shafts are respectively fixed to adjacent rotating shafts by couplings, the outer arc surfaces of the rotating shafts are fixedly sleeved with worm gears, four evenly distributed supports are arranged inside the two drive boxes, and the supports on the front and rear sides are respectively rotatably arranged with worms on the sides away from the vertical center of the movable seat and between the adjacent inner walls of the drive boxes, the worms are respectively meshed and connected with adjacent worm gears, and an electric drive unit for driving the worm to rotate is also arranged on the drive box; the electric drive unit includes a linkage rod rotatably arranged between two adjacent supports, the linkage rods are respectively fixed to adjacent worm gears by couplings, a dual-axis motor 1 is arranged in the middle part of the interior of the two drive boxes, and the output shafts of the dual-axis motor 1 are respectively fixed to adjacent linkage rods by couplings.

[0007] As a further improvement of the present invention, the electric control module includes two support plates symmetrically welded and fixed inside the moving seat, and two guide rails symmetrically distributed up and down are arranged between the side of the support plate away from the vertical center of the moving seat and the adjacent inner wall of the moving seat, and sliding seats are slidably arranged between the two vertically adjacent guide rails, and connecting rods are rotatably arranged on the left and right sides of the sliding seat, and the ends of the connecting rods away from the sliding seat are rotatably connected to the adjacent movable arms, and an electric control unit for driving the sliding seat to move is also arranged on the moving seat; the electric control unit includes an adjusting screw rotatably arranged between the support plate and the adjacent inner wall of the moving seat, and the adjusting screws are respectively threadedly connected to the adjacent sliding seats, and a dual-axis motor 2 is arranged between the two support plates, and the output shafts of the dual-axis motor 2 are respectively fixed to the adjacent adjusting screws through couplings.

[0008] As a further improvement of the utility model, a control board is arranged on the lower surface of the movable seat, and two symmetrically distributed lithium batteries are arranged on the inner walls on both the front and rear sides of the movable seat, and the lithium batteries, dual-axis motor one and dual-axis motor two are all electrically connected to the control board.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] First, after placing the moving seat in a suitable position, the control panel uses a lithium battery to drive the dual-axis motor 2 under the control of an external controller, so that the sliding seats on the front and rear sides drive the movable arms on the left and right sides to slide with the moving seat through the connecting rod, so that the movable arms on the left and right sides move closer to each other, and then drive the running wheels on the left and right sides to move closer to each other, so that the running wheels are installed on the track, thereby realizing the rapid installation of the crane.

[0011] Secondly, under the control of an external controller, the control board uses the electricity from the lithium battery to drive the dual-axis motors on the left and right sides to run synchronously. The meshing relationship between the worm and the worm wheel drives the rotating shaft to rotate, and then drives the running wheels on the left and right sides to rotate synchronously. At this time, the rotation of the running wheels on the track can drive the monorail crane to move quickly and stably.

[0012] Thirdly, when the monorail crane needs to be stopped, the control panel is used to control the double-axis motor 1 on the left and right sides to stop running and the double-axis motor 2 to start. The meshing relationship between the worm and the worm wheel drives the traveling wheels to self-lock, so that the traveling wheels quickly stop rotating, and the movable arms on the left and right sides continue to move toward each other, thereby driving the rotating seats on the left and right sides to quickly approach the track until the brake block contacts the track. When the crane needs to be controlled to stop, by controlling the traveling wheels to quickly stop rotating and making the brake block quickly approach the track, the position of the crane can be effectively guaranteed to be quickly and stably braked, and the position of the crane can be accurately controlled.

[0013] Fourthly, the rubber pad can make the material box and the hanger flexibly contact when the material box is installed between the hangers, which can effectively prevent the material box or the hanger from being damaged during the installation process during use.

[0025] When the monorail crane is needed, after the moving seat 101 is placed in a suitable position, the control panel 302 uses the lithium battery 301 to drive the dual-axis motor 206 to operate under the control of the external controller, so that the output shafts of the dual-axis motor 206 respectively drive the adjusting screw rod 205 connected thereto to rotate, and then the sliding seats 203 on the front and rear sides are driven to move closer to each other through the threaded relationship between the adjusting screw rod 205 and the sliding seat 203. During the movement of the sliding seat 203: the sliding seat 203 and the connecting rod 204 rotate, and the connecting rod 204 rotates with the movable arm 1 03 rotates, so that the sliding seats 203 on the front and rear sides drive the movable arms 103 on the left and right sides to slide with the moving seat 101 through the connecting rod 204, so that the movable arms 103 on the left and right sides move closer to each other, and then drive the running wheels 108 on the left and right sides to move closer to each other, so that the running wheels 108 are installed on the track; under the control of an external controller, the control board 302 uses the electricity of the lithium battery 301 to drive the double-axis motors 114 on the left and right sides to run synchronously, so that the output shafts of the double-axis motors 114 respectively drive the linkage rods 113 connected thereto to rotate, and the running wheels 108 are installed on the track.
