Description

Technical Field

[0001] The utility model relates to a telescopic standing platform of cave mining equipment. Background Art

[0002] When mining in a mine cave, it is necessary to drill holes first and then use a rope saw to cut the seams. The existing mine cave mining equipment is not convenient to adjust the center position of the drill hole when drilling, which seriously affects the efficiency of the cave mining. Therefore, a new type of mine cave drilling machine is needed, and CN112709531A discloses a new type of mine cave drilling machine and its working method. When it is working, the sleeve assembly of the drilling component is connected to the telescopic end of the telescopic arm, and the drilling motor drives the coring drill bit to rotate through the drill rod. Then the lifting frame moves forward through the walking mechanism at the bottom, and the coring drill bits on the left and right sides of the lifting frame drill holes in the stone body. A split frame is adopted, and the upper and lower bodies can be disassembled during transportation to improve the convenience of transportation; at the same time, a scissor lift assembly is set between the upper and lower bodies to adjust the height of the entire frame and facilitate the adjustment of the center position of the drill hole. However, long-term use requires regular maintenance and it is inevitable that damage will occur and require repair. Due to the high overall height, maintenance personnel are required to climb up and inspect using a ladder. Each time they check a location, they need to come down and set up the ladder in another position, which is very inconvenient and affects maintenance efficiency and poses a safety hazard. Therefore, there is an urgent need for a standing platform that is safer, easy to assemble and disassemble, and can better cooperate with the mine cave drilling machine. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0018] like Figures 1 to 3 As shown, the telescopic standing platform of the cave mining equipment includes fixed sleeves 2 symmetrically arranged on both sides of the cave mining equipment body 1 in the horizontal direction, the fixed sleeves are extended longitudinally and the interiors thereof are slidably connected with a telescopic sleeve 4 driven by a lead screw 3, that is, the lead screw extends into the telescopic sleeve and is connected to the telescopic sleeve through a lead screw nut, the longitudinally extending ends of the two lead screws in the fixed sleeve are driven by a driving member, a manual sleeve 5 is slidably connected inside the telescopic sleeve, a sliding rail or pulley for facilitating sliding can be arranged between the manual sleeve and the telescopic sleeve, a pull ring 6 is fixedly arranged at the outer end of the manual sleeve, and a platform plate 7 is horizontally arranged between the two telescopic sleeves or between the two manual sleeves.

[0019] In the embodiment of the utility model, the opposite rotation of the lead screw or the opposite rotation of the output ends of the reducer to keep the two telescopic sleeves moving synchronously are common settings and will not be described in detail here.

[0020] In the embodiment of the utility model, the outer end of the telescopic sleeve is provided with a self-locking indexing pin 8, which is a knob plunger indexing pin with a built-in spring and a lifting brake self-locking function. When the operator pulls the knob handle, it can be lifted up and then rotated 90 degrees to prevent the front end protrusion from resetting. If it needs to be released, the knob plunger indexing pin can be freely returned to its original position by rotating it 90 degrees in the opposite direction and releasing the knob handle. The plug-in end of the self-locking indexing pin passes through the telescopic sleeve and is plugged into the limit hole opened on the manual sleeve inside it. The limit hole 9 is located on the end of the manual sleeve away from the pull ring. Multiple limit holes can be arranged at intervals along the length direction of the manual sleeve to limit different telescopic lengths.

[0021] In an embodiment of the utility model, the driving group includes a driving motor 10, a reducer 11, a linkage rod 12 and a bevel gear 13. The driving motor is connected to the reducer, and linkage rods are connected on both sides of the output end of the reducer. The two linkage rods extend laterally opposite to each other and bevel gears are arranged at the ends. The ends of the two screw rods are meshed and linked with the bevel gears on the two linkage rods through the bevel gears.

[0022] In the embodiment of the utility model, a limit ring 14 is sleeved and fixed along the outer circumference of the outer end of the telescopic sleeve, and the edge size of the limit ring is larger than the inner circumference size of the end face of the fixed sleeve to prevent the telescopic sleeve from being over-retracted.

[0023] In the embodiment of the utility model, the upper and lower ends of the fixed sleeve are connected and fastened to the main body of the hole mining equipment via a triangular reinforcement plate 15 .

[0024] In the embodiment of the utility model, a baffle 16 is fixedly provided at the outer end of the manual sleeve, and the upper end of the baffle protrudes from the manual sleeve to prevent the risk of the erected platform board from longitudinally escaping, thereby ensuring the safety of the staff's operation, and the pull ring is fixedly connected to the lower end of the baffle.

[0025] In the embodiment of the utility model, the cross-sections of the fixed sleeve, the telescopic sleeve and the manual sleeve are all square.

[0026] The working principle of the embodiment of the utility model is as follows: when in use, the driving motor is started, and the driving motor drives the two linkage rods to rotate through the reducer, and then drives the lead screw to rotate synchronously, so that the telescopic sleeve can be extended. At this time, a platform board can be set up between the two telescopic sleeves, and the operating personnel stand on the platform board to perform maintenance work. If more maintenance personnel are needed, the pull ring can be pulled again, the manual sleeve can be manually pulled outward, and the self-locking indexing pin can be rotated until the self-locking indexing pin is pushed into the limit hole to complete the locking limit. At this time, multiple platform boards can be set up to increase the working space for maintenance personnel.

[0027] The present invention is not limited to the above-mentioned best implementation mode. Anyone can derive other various forms of telescopic standing platforms for hole mining equipment under the inspiration of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
