Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, specifically to a walking device for mining equipment. Background Technology

[0002] Mining operations are typically conducted underground or in mountainous areas with complex terrain, narrow tunnels, and uneven surfaces with varying degrees of slope. Mining requires the use of a wide variety of tools and equipment, some of which are heavy and inconvenient and need to be moved by miners. Therefore, these tools and equipment are often moved by carts.

[0003] Traditional pushcarts rely heavily on manual control or simple manual brakes. When encountering long downhill slopes or heavy loads with excessive inertia, if the operator loses control or reacts too late, the vehicle is prone to runaway and accelerate (commonly known as "runaway"), causing serious safety accidents. Summary of the Invention

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-5 The present invention provides a technical solution: a walking device for mining equipment, comprising a base plate 1, two mounting frames 2 mounted on the left and right ends of the top surface by bolts, a braking assembly 3 mounted inside the mounting frame 2, a first electric telescopic rod 4 mounted on the outer side of the mounting frame 2 by bolts, a wedge block 5 mounted on the telescopic end of the first electric telescopic rod 4 by bolts, two first fixing plates 6 welded to the front and rear ends of the top surface of the base plate 1, two positioning components 7 symmetrically distributed and mounted on the sides of the first fixing plates 6, an adjusting assembly 8 mounted in the middle of the bottom surface of the base plate 1, and two limiting components 10 symmetrically distributed and mounted at both ends of an L-shaped plate 9.

[0018] The braking assembly 3 includes a first mounting plate 31, a spring 32, a second mounting plate 33, and a brake block 34. The first mounting plate 31 is bolted to the top wall of the mounting bracket 2. The top of the spring 32 is welded to the bottom surface of the first mounting plate 31, and the second mounting plate 33 is welded to the bottom of the spring 32. The top of the brake block 34 has a groove, and the second mounting plate 33 is bonded to the inside of the groove. The brake block 34 penetrates the bottom plate 1, and a friction surface is installed on the bottom surface of the brake block 34. The friction surface can be knurled or an attached friction pad, which is used to increase the friction force when locking. When the roller 13 moves, the spring 32 is in a pre-compressed state, lifting the brake block 34 upward, so that the friction pad and the roller shaft 12 maintain a certain gap. When the roller 13 overspeeds or stops, the first electric telescopic rod 4 is activated to push out the wedge 5. The inclined surface of the wedge 5 forcibly presses down the brake block 34, overcoming the spring force, so that the friction pad instantly locks the connecting shaft 12.

[0019] The positioning assembly 7 includes a second electric telescopic rod 71, a pressure sensor 72, and a positioning plate 73. The second electric telescopic rod 71 is bolted to one end of the side of the first fixed plate 6. The pressure sensor 72 is threaded to the telescopic end of the second electric telescopic rod 71. The positioning plate 73 is bolted to the side of the pressure sensor 72 away from the second electric telescopic rod 71. The side of the positioning plate 73 has multiple mounting holes. The second electric telescopic rod 71 has a self-locking function and maintains clamping force even after power failure. When the second electric telescopic rod 71 is activated, it drives the positioning plate 73 to extend synchronously, so that the positioning plate 73 fits against the surface of the mining equipment, thereby initially fixing the mining equipment.

[0020] The adjusting assembly 8 includes a motor 81, a lead screw 82, a second fixed plate 83, two sliders 84, multiple connecting rods 85, and two connecting frames 86. The motor 81 is bolted to one end of the bottom surface of the base plate 1. One end of the lead screw 82 is mounted on the output shaft of the motor 81 via a coupling, and the other end of the lead screw 82 is rotatably connected to the middle of the second fixed plate 83 via a bearing. The second fixed plate 83 is welded to the bottom surface of the base plate 1. The threads at both ends of the second fixed plate 83 have opposite directions. The lead screw 82 is a trapezoidal threaded lead screw with self-locking capability. The two sliders 84 are threaded to both ends of the second fixed plate 83. One end of the multiple connecting rods 85 is hinged to one end of the two sliders 84 via a pin, and the other end of the multiple connecting rods 85 is hinged to the inside of the two connecting frames 86 via a pin. The two L-shaped plates 9 are bolted to the sides of the two connecting frames 86. When the motor 81 is started, the motor 81 drives the lead screw 82 to rotate, causing the two sliders 84 to move closer to each other. The connecting rods 85 drive the connecting frames 86 to extend, thereby adjusting the distance between the two L-shaped plates 9.

[0021] The limiting component 10 includes a third electric telescopic rod 101 and an insert rod 102. The third electric telescopic rod 101 is bolted to one end of the surface of the L-shaped plate 9. The insert rod 102 is threaded to the bottom end of the third electric telescopic rod 101. When the third electric telescopic rod 101 is activated, it drives the insert rod 102 to insert into the mine surface, thereby providing extremely strong resistance to horizontal displacement.

[0022] Multiple support frames 11 are bolted to the corner of the bottom surface of the base plate 1. A connecting shaft 12 is rotatably connected between the middle of two support frames 11 via a bearing. A friction surface is installed in the middle of the connecting shaft 12. The friction surface can be knurled or an attached friction plate to increase the friction force when locking. Two rollers 13 are bolted to both ends of the connecting shaft 12. Two speed sensors are bolted to both ends of the bottom surface of the base plate 1.

[0023] Multiple through holes are provided on the front and rear sides of the base plate 1. Multiple sliding rods 14 are installed on the side of the L-shaped plate 9 by bolts. The sliding rods 14 are installed inside the through holes. When the adjusting component 8 moves the L-shaped plate 9 outward, the sliding rods 14 slide inside the through holes, thereby maintaining the smooth movement of the L-shaped plate 9.

[0024] The handrail 15 is bolted to one end of the top surface of the base plate 1. The control panel 16 is bolted to the middle of the handrail 15. The battery is bolted to one end of the top surface of the base plate 1. The control panel 16 integrates switches and programmable controllers that are compatible with various electronic devices. It is electrically connected to each electronic device through wires and the battery provides power to the entire device. The control panel can operate each switch to control the opening and closing of each electronic device. The above-mentioned electronic devices are all existing technologies, and their specific structures, working principles and electrical connections are not detailed here.

[0025] Working principle: When using this invention, the mining equipment is first placed on the base plate 1. The operator starts the second electric telescopic rod 71 through the control panel 16. The second electric telescopic rods 71 ​​on both sides drive the positioning plate 73 to extend synchronously, so that the positioning plate 73 fits against the surface of the mining equipment. The pressure sensor 72 monitors the contact pressure between the positioning plate 73 and the surface of the equipment in real time. When the pressure value reaches the preset safety threshold (clamping without damaging the equipment), the control panel 16 stops the action of the second electric telescopic rod 71. Then, the mining equipment is fixed to the side of the positioning plate 73 with bolts. The operator pushes the handle 15, and the rolling of the roller 13 moves the mining equipment to the designated position. During the movement, the first electric telescopic rod 4 is in the retracted state, the wedge 5 moves away from the brake block 34, and the spring 32 pulls the brake block 34 upward to separate it from the connecting shaft 12. The wheel rolls normally. If the vehicle speed is out of control due to a downhill slope, the speed sensor detects that the speed is too high and sends a signal to the control panel 16. The control panel 16 activates the first electric telescopic rod 4, which drives the wedge 5 to extend. Using the principle of inclined plane, the wedge 5 forcefully squeezes the brake block 34, causing the brake block 34 to move downward. The friction surface at the bottom of the brake block 34 then tightly presses against the friction surface of the connecting shaft 12, achieving emergency braking and preventing accidents. After being moved to the designated position, the operator starts the motor 81 via the control panel 16. The motor 81 drives the lead screw 82 to rotate, causing the two sliders 84 to move closer to each other. At the same time, the connecting rod 85 drives the connecting frame 86 to extend, thereby increasing the distance between the two L-shaped plates 9. After the L-shaped plates 9 are fully extended, the third electric telescopic rod 101 is activated. The third electric telescopic rod 101 drives the insertion rod 102 to insert into the mine ground. Together with the locked wheels, it forms a multi-point rigid anchor, ensuring that the chassis of the mining equipment will not shift when operating under high vibration. This invention has the advantages of being easy to use and having good performance.
