Description

Technical Field

[0001] This utility model relates to the field of general underground equipment, and in particular to a new type of coal feeder lifting lug and replacement component. Background Technology

[0002] Coal feeders are common equipment in industrial and mining enterprises. The existing technology using internally clipped lifting lugs for coal feeders has significant drawbacks in actual maintenance. Due to the internal clip design of the lugs interfering with the feeder's base plate, the feeder cannot be directly and vertically disassembled. In this situation, maintenance personnel must perform secondary cutting and segmented disassembly, which not only prolongs maintenance time and requires a large number of workers, increasing labor intensity, but also significantly jeopardizes construction safety. More specifically, even when the aforementioned solution is used to cut the feeder's central shaft, the lifting lugs are still assembled using hand-operated hoists during bolt removal. The sudden movement of the workpiece during disassembly poses a significant risk of injury. Currently, there is a lack of corresponding solutions to these problems. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of coal feeder lifting lug and replacement component that modifies the lifting lug and configures disassembly equipment according to the modified lifting lug, so that the disassembly work is smooth and safe and reduces the manpower required.

[0004] The equipment includes a lifting lug unit and a tow wheel replacement unit; The lifting lug unit includes an assembly horizontal plate, and the assembly horizontal plate is provided with assembly holes corresponding to the coal feeder assembly lugs; A wheel mounting lug is provided on the bottom surface of the mounting cross plate; The outer side of the tug wheel mounting lug is integrally connected with the mounting cross plate and is provided with a support partition perpendicular to the mounting cross plate. The tugboat replacement unit includes a support frame, which is a U-shaped bracket with its opening facing upwards. The distance between its two ends corresponds to the setting of the support partition. That is, after the assembly of the horizontal plates on both sides of the coal feeder is completed, it is greater than the distance between the two support partitions and less than the distance between the outer edges of the two support horizontal plates. The support frame is equipped with a lifting mechanism on its bottom surface; The lifting mechanism is equipped with rollers underneath.

[0005] The effect achieved in this way is as shown in the attached diagram of the instruction manual. Figure 1 As shown, the lifting mechanism's lifting action causes the support frame to fit into the coal feeder's lifting lugs, thus providing support. After disassembling the bolts between the assembly horizontal plate and the coal feeder assembly lugs, the equipment is stably supported by the support frame after disassembly, with the support of the lifting mechanism. Lower the lifting mechanism to remove it from the interference range of the coal feeder's bottom plate, and use the rollers at the bottom of the tow wheel replacement unit to simultaneously transfer the old tow wheel and its lifting lugs to the outside of the equipment, thus completing the dismantling process; When replacing a tugboat, simply reverse the steps described above to complete the assembly of the new tugboat.

[0006] The beneficial effects of this utility model are as follows: This utility model solves the problem of inconvenient removal of the lifting lugs of the coal feeder in the prior art. It modifies the lifting lugs and equips them with a towing wheel replacement unit based on the lug design. Compared with the traditional method of replacing the cutting spindle, this equipment is more convenient and faster to use, and it can greatly improve the safety of the replacement operation, making it more valuable for safe promotion.

Detailed Implementation

[0008] Reference Figure 1 , Figure 2 The present invention provides a novel coal feeder lifting lug and replacement assembly, comprising a lifting lug unit 1 and a towing wheel replacement unit 2. The lifting lug unit 1 includes an assembly horizontal plate 12, on which assembly holes corresponding to the coal feeder assembly lugs are provided. A wheel mounting lug 14 is provided on the bottom surface of the mounting cross plate 12; Preferably, the tugboat mounting lug 14 is flange-connected to the tugboat.

[0009] The outer side of the tug wheel mounting lug 14 is integrally connected with the mounting cross plate 12, and a support partition 13 perpendicular to the mounting cross plate 12 is provided. The purpose of implementing the support partition 13 is to cooperate with the tugboat replacement unit 2 to achieve positioning support.

[0010] The tugboat replacement unit 2 includes a support frame 23, which is a U-shaped bracket with its opening facing upward. The distance between its two ends corresponds to the support partition 13. That is, after the assembly of the horizontal plates 12 on both sides of the coal feeder, the distance is greater than the distance between the two support partitions 13 and less than the distance between the outer edges of the two support horizontal plates. The bottom surface of the support frame 23 is provided with a lifting mechanism 24; The lifting mechanism 24 is provided with rollers 25 underneath.

[0011] Furthermore, the support frame 23 is a wide support frame welded from thick steel plates, and reinforcing ribs 21 are provided between its two side plates and the bottom plate.

[0012] When using, please refer to the attached diagram in the instruction manual. Figure 1 As shown, the lifting mechanism 24 lifts the support frame 23 so that it fits into the coal feeder's lifting lugs, thus providing support. After the bolts between the assembly horizontal plate 12 and the coal feeder assembly lug are removed, the equipment is stably supported by the support frame 23 after disassembly, with the support of the lifting mechanism 24. Lower the lifting mechanism 24 to remove it from the interference range of the coal feeder base plate. Use the rollers 25 at the bottom of the tow wheel replacement unit 2 to transfer the old tow wheel and its lifting lugs to the outside of the equipment simultaneously to complete the dismantling process. When replacing a tugboat, simply reverse the steps described above to complete the assembly of the new tugboat.

[0013] In Example 1, a limiting guard plate 11 is also provided at the outer end of the assembly cross plate 12, that is, an assembly groove is formed between the limiting guard plate 11 and the supporting partition plate 13.

[0014] This is how the support frame 23 is precisely positioned.

[0015] In Example 2, the lifting mechanism 24 is a hydraulic cylinder, an air cylinder, or a jack. A hydraulic cylinder is preferred.

[0016] This achieves the effect of enabling rapid power connection of equipment using readily available hydraulic lines downhole.

[0017] In Example 3, a long push handle 22 is also provided on the side of the lifting mechanism 24.

[0018] This facilitates construction operations under the scaffold, such as adjusting equipment positions and moving equipment in and out.

[0019] In Example 4, a roller 25 assembly box is fixedly provided at the lower part of the lifting mechanism 24, and multiple sets of rollers 25 are evenly arranged in the roller 25 assembly box.

[0020] This achieves the effect of ensuring smooth movement of the equipment.
