Description

Technical Field

[0001] This utility model belongs to the field of coal mine electromechanical equipment maintenance technology, and in particular relates to a coal mine electromechanical equipment maintenance and testing device. Background Technology

[0002] Coal mining operations require a large number of mining equipment, including large fully mechanized mining machines and hydraulic supports. The size and height of this equipment make subsequent maintenance, repair, and inspection difficult, especially during maintenance, which often requires workers to climb to the top of the equipment to perform repairs and inspections, such as replacing the roof of a hydraulic support in a roadway.

[0003] The current operating method involves using a lift, with operators working after the lift is raised.

[0004] However, in actual operation, due to the location of maintenance equipment, there is a large distance between the operator and the maintenance part after the operator climbs up on the maintenance platform of the elevator, making it difficult to conveniently maintain, inspect, or disassemble the equipment during operation.

[0005] The specific reason is that in existing publicly available maintenance equipment, the maintenance platform on the lift cannot be moved horizontally to a position close to the top of the equipment, making it convenient for workers to approach and operate the equipment. Furthermore, horizontal movement of the maintenance platform results in low stability and poses a significant risk during maintenance.

[0006] Furthermore, because the maintenance platform cannot move horizontally during the maintenance process, the distance between the operator and the maintenance equipment cannot be flexibly adjusted. This has the drawback that when large parts are being removed from the equipment, the distance between the maintenance platform and the equipment needs to be adjusted flexibly. This is to facilitate the operator's placement of the disassembled parts on the maintenance platform from a better position, and also to facilitate the movement of the parts onto the equipment platform. Therefore, an adjustable maintenance platform is crucial for improving maintenance efficiency, increasing flexibility during the maintenance process, and enhancing the safety of maintenance operations.

[0020] Preferably, the hydraulic cylinder structure includes a hinged hydraulic cylinder, the cylinder barrel of which is hinged to a long fixed rod, and the long fixed rod is fixed between vertical supports;

[0021] The piston rod of the hydraulic cylinder is hinged between the lower lifting arms, and a fixed crossbeam is fixedly connected between the lower lifting arms. The piston rod of the hydraulic cylinder is hinged to the center of the fixed crossbeam.

[0022] Preferably, a vertically arranged mounting platform is fixedly connected to the inner end of the inspection platform;

[0027] Preferably, a crossbeam is fixedly connected between the outer ends of the slide rail, and a bearing bracket for rotating connecting screw is installed on the crossbeam.

[0028] Preferably, the upper end of the long inclined support is hinged to the outer end of the slide rail by a pin.

[0029] An elastic buckle structure is fixedly connected to the outer wall of the base platform, and the elastic buckle structure is locked to the lower end of the long inclined bracket.

[0048] Example 1

[0049] like Figure 1-6 As shown, a coal mine electromechanical equipment maintenance and testing device includes a maintenance platform mechanism installed on a hoist. Specifically, the hoist is a conventional hoist disclosed in the prior art, and the maintenance platform mechanism is fixedly installed on the lifting platform of the hoist. During operation, the hoist is raised in height, and the maintenance platform mechanism is used to adjust the horizontal distance between the device and the equipment.

[0050] Specifically, the maintenance platform mechanism includes a frame, the structure of which is as follows: the frame includes a base platform 12 mounted on the elevator, and a pair of vertical supports 11 are fixedly connected to the top left side of the base platform 12; the vertical supports 11 are welded to the front and rear edges of the base platform 12. An upper crossbeam 14 is fixedly connected to the top of the vertical supports 11.

[0051] Meanwhile, a diagonal fixed bracket 13 is welded between the vertical bracket 11 and the base platform 12.

[0052] The aforementioned frame is hinged with a lifting frame structure, specifically, the lifting frame structure includes a pair of upper lifting arms 21 and a pair of lower lifting arms (each pair of lifting arms is spaced apart front and rear).

[0053] Meanwhile, the upper lifting arm 21 is hinged to the upper crossbeam 14, and the lower lifting arm is hinged to the upper end of the vertical support 11. Specifically, the hinges are as follows: the outer ends of the upper lifting arm 21 and the lower lifting arm are respectively fixedly connected to hinge shafts 22, and the two ends of the hinge shafts 22 are hinged to hinge seats, which are fixed to the corresponding upper crossbeam 14 and vertical support 11.

[0054] At the same time, in order to lift the lifting frame structure from a tilted state (when the entire device occupies the least space and is easy to move) to a horizontal state.

[0055] The aforementioned frame is equipped with a hydraulic cylinder structure for raising and lifting the frame.

[0056] Specifically, the hydraulic cylinder structure includes a hydraulic cylinder 23 with a hinged arrangement. The cylinder barrel of the hydraulic cylinder 23 is hinged to a long fixed rod (a hinge tongue plate is fixedly connected to the cylinder barrel, and the hinge tongue plate is hinged to the long fixed rod). The long fixed rod is fixed between the lower sides of the vertical support 11.

[0057] Meanwhile, the piston rod of the hydraulic cylinder 23 is hinged between the lower lifting arms. Specifically, a fixed crossbeam 211 is fixedly connected between the lower lifting arms, and the piston rod of the hydraulic cylinder 23 is hinged to the center of the fixed crossbeam 211.

[0058] Specifically, a hinge seat is fixedly connected to the bottom of the fixed crossbeam 211, and a hinge tongue is fixedly connected to the piston rod of the hydraulic cylinder 23. The hinge tongue is hinged to the hinge seat by a pin.

[0059] During operation, the operator opens the hydraulic cylinder 23, which drives the plunger rod to push up the fixed crossbeam 211. Because the hydraulic cylinder 23 is hinged, after being pushed up, the lifting frame structure gradually rises from a downward tilting state to a horizontal state. At this time, the lifting platform is raised to the height corresponding to the maintenance part of the maintenance equipment, which facilitates maintenance.

[0060] The aforementioned lifting frame structure is equipped with a maintenance platform structure, which includes a maintenance platform 4. The upper and lower lifting arms are mounted on the maintenance platform 4 in the following manner and structure:

[0061] The inner end of the inspection platform 4 is fixedly connected to a vertically set installation platform 3; the upper lifting arm 21 and the lower lifting arm are installed on the installation platform 3, specifically using a fixed installation method.

[0062] In order to enable the maintenance platform 4 to be moved during the operation, the relative distance between the maintenance platform 4 and the maintenance equipment can be adjusted by horizontal movement adjustment, so as to facilitate the maintenance of the equipment by the operators in the best position, and the disassembled parts can be transported to the maintenance platform 4 in the best spatial position.

[0063] Specifically, the bottom of the aforementioned inspection platform 4 has a pair of sliding rails 31 that are spaced apart and fixedly connected to the lifting frame structure.

[0064] Specifically, a pair of slide blocks 42 are fixedly installed on the bottom sides of the inspection platform 4, which are spaced apart and slidably connected to the slide rail 31. The slide blocks 42 are T-shaped, and the corresponding slide rail 31 has a matching T-shaped groove.

[0065] During operation, the maintenance platform 4 is limited to sliding on the slide block through the aforementioned slide block 42 and T-shaped slide groove structure.

[0066] Meanwhile, a lead screw structure that drives the maintenance platform 4 to move is installed on the lifting frame structure. Specifically, the lead screw structure includes a lead screw motor 5 fixedly installed on the mounting platform 3; a lead screw 51 is installed on the output shaft of the lead screw motor 5; and a lead screw seat 41 with a threaded connection to the lead screw 51 is installed at the bottom of the maintenance platform 4.

[0067] A crossbeam is fixedly connected between the outer ends of the slide rail 31, and a bearing bracket for rotating the lead screw 51 is mounted on the crossbeam.

[0068] During operation, the operator turns on the lead screw motor 5. At this time, driven by the lead screw motor 5, the maintenance platform 4, which is threadedly connected to the lead screw seat 41, moves. In this way, the maintenance platform 4 can be easily moved horizontally to the optimal position for maintenance equipment.

[0069] The top of the aforementioned maintenance platform 4 is equipped with a guardrail, allowing workers to operate within the enclosed environment created by the guardrail, thereby increasing operational safety.

[0070] Example 2

[0071] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 1, since the slide rail 31 is extended, in order to improve the stability of the maintenance platform 4, especially when moving to the outer end of the slide rail 31, and to ensure the stability and safety of the maintenance platform 4, the outer end of each slide rail 31 is supported by an inclined long bracket 6.

[0072] Specifically, the outer end of the slide rail 31 is supported by an inclined long bracket 6, and the upper end of the long bracket 6 is hinged to the outer end of the slide rail 31 by a pin.

[0073] Meanwhile, an elastic buckle structure 61 is fixedly connected to the outer wall of the base platform 12, and the elastic buckle structure 61 is locked at the lower end of the long inclined bracket 6.

[0074] Specifically, the elastic buckle structure includes a bracket 614 fixedly connected to the base platform 12, a locking rod 611 slidably connected to the bracket 614, and a spring 612 sleeved on the locking rod 611. Specifically, the outer end of the locking rod 611 is fixedly connected to a spring seat 613, the inner end of the spring 612 is fixedly connected to the bracket 614, and the outer end is fixed to the spring seat 613.

[0075] Meanwhile, the end of the locking bar 611 is integrally formed with a curved part 6111.

[0076] During operation, the long inclined bracket 6 is first flipped to its lower end near the curved part on the locking rod 611. At this time, the operator pulls the locking rod 611. With the elastic restoring force of the spring 612, the locking rod 611 locks into the locking hole at the lower end of the long inclined bracket 6. This method supports the outer end of the slide rail 31, thereby maintaining the stability of the slide rail 31. Especially when the maintenance platform 4 moves to the outer end of the slide rail 31, the stability is further increased under the support of the long inclined bracket 6.

[0077] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
