Description

Technical Field

[0001] This utility model relates to the technical field of shovel-type bracket transport vehicles, and in particular to the end fixing structure of the steel wire rope of the traction part of the shovel-type bracket transport vehicle. Background Technology

[0002] The term "shovel-type support transport vehicle" generally refers to all vehicle-type equipment capable of transporting support products involved in various social production and business activities. In actual production practice, it specifically refers to hydraulic supports and their transport equipment used in mining. It is a new type of special vehicle or special transport tool developed and designed specifically for the transport or long-distance transportation of hydraulic supports during the relocation and face-changing process of fully mechanized mining faces (it can be broadly understood and extended to large, difficult-to-transport machinery such as shovel trucks in mining).

[0003] The existing wire rope end fixing structure of the traction unit of the shovel-type support transport vehicle uses the method of inserting and braiding wire rope to fix the end of the wire rope on site. Then, a specified number of rope clamps are used to press the main rope and the rope head together. This method requires disassembling the original wire rope head and re-braiding it manually during operation.

[0004] However, during the on-site manual reweaving process, the original structural properties of the wire rope were damaged, resulting in reduced load-bearing capacity, decreased wear resistance, and shorter service life. This also led to frequent replacement of the wire rope on-site, increasing the project's material costs. In addition, the spliced ​​wire rope was prone to breakage at the ends when pulling equipment, posing a significant safety hazard. Utility Model Content

[0005] In response to the technical problem that existing shovel-type support transport vehicles use braided steel wire ropes to fix the ends of the wire ropes, the structural properties of the wire ropes are damaged during the on-site manual re-braiding process, and the wire rope ends are prone to breakage and injury, posing a significant safety hazard, this utility model provides a wire rope end fixing structure for the traction part of the shovel-type support transport vehicle.

[0006] The technical solution of this utility model is as follows: a wire rope end fixing structure for the traction part of a shovel-type bracket transport vehicle, including a shovel-type bracket transport vehicle body; it also includes a protective rotating shaft and a fixing component; a machine head frame is provided on one side of the shovel-type bracket transport vehicle body, a shovel body is provided on one side of the machine head frame, a protective rotating shaft is rotatably connected to the inner side of the machine head frame, a wire rope body is provided on one side of the machine head frame, the protective rotating shaft is used for contact between the wire rope body and the sharp edge of the machine head frame, a loose wire rope is provided at one end of the wire rope body, a connecting fixing sleeve is cast on the loose wire rope, a hanging ear is provided on one side of the fixing sleeve, and a fixing component is provided inside the hanging ear.

[0007] Preferably, a slot is provided on the head frame, and the protective rotating shaft is rotatably connected to the inner side of the head frame through the slot.

[0008] Preferably, multiple sets of protective rotating shafts are provided, and the array of multiple sets of protective rotating shafts is arranged on the inner side of the head frame.

[0009] Preferably, the internal cavity of the fixing sleeve is conical, and the diameter of the end of the fixing sleeve cavity closest to the wire rope body is the smaller diameter.

[0010] Preferably, the fixing component includes a limiting pin, a limiting pin is provided on the inner side of the lug, a spring is provided on the inner side of the limiting pin, a slider is provided on one side of the spring, and a stop is provided on one side of the slider to limit the limiting pin.

[0011] Preferably, the ear has a second groove, and the limiting pin is movably connected to the inside of the ear through the second groove.

[0012] Preferably, the limiting pin has a groove three, and the slider is slidably connected to the inside of the limiting pin through the groove three.

[0013] The beneficial effects of this utility model are as follows: Compared with traditional shovel-type support transport vehicles, where the ends of the wire ropes are fixed by inserting braided wire ropes, the structural properties of the wire ropes are damaged during the on-site manual reweaving process, and the wire rope ends are prone to breakage and injury, posing a significant safety hazard. This device fixes one end of the wire rope body to the machine head frame and inserts the other end into a cable joint. Iron wire is tied at the head of the wire rope body, and all the strands at the head of the wire rope body are disassembled into loose wire ropes. The disassembled loose wire ropes resemble a brush. Each wire is then bent, and the grease on the wires is cleaned with a cleaning agent. The rope is then firmly pulled into the cable joint, and the cable joint is fully heated with an oxygen torch. Molten Babbitt alloy is poured into the cable joint, fusing the loose wire ropes and the cable joint into one piece. It can only be used after cooling, thus ensuring the stability of the wire rope's structural properties and significantly improving its load-bearing capacity, wear resistance, service life, and safety.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a wire rope end fixing structure for the traction part of a shovel-type bracket transport vehicle, including a shovel-type bracket transport vehicle body 1; it also includes a protective rotating shaft 401 and a fixing assembly; a machine head frame 2 is provided on one side of the shovel-type bracket transport vehicle body 1, a shovel body 3 is provided on one side of the machine head frame 2, the protective rotating shaft 401 is rotatably connected to the inner side of the machine head frame 2, and a wire rope body 402 is provided on one side of the machine head frame 2. The protective rotating shaft 401 is used for contact between the wire rope body 402 and the sharp edge of the machine head frame 2. One end of the wire rope body 402 is provided with a loose wire rope 405. A connecting fixing sleeve 403 is cast on the loose wire rope 405. A hanging ear 404 is provided on one side of the fixing sleeve 403. A fixing component is provided inside the hanging ear 404. A slot is opened on the head frame 2. The protective rotating shaft 401 is rotatably connected to the inside of the head frame 2 through the slot. The slot on the head frame 2 provides a limiting effect when the protective rotating shaft 401 rotates inside the slot. Multiple sets of protective rotating shafts 401 are provided. The protective shafts 401 are arranged inside the headstock 2, with multiple sets to prevent the wire rope body 402 from being damaged by friction with the sharp edges of the headstock 2. The internal cavity of the fixing sleeve 403 is conical, with the smaller diameter hole at the end of the fixing sleeve 403 closest to the wire rope body 402. The conical shape of the internal cavity of the fixing sleeve 403 makes the connection between the loose wire rope 405 and the fixing sleeve 403 more secure. By fixing one end of the wire rope body 402 to the headstock 2 and inserting the other end into the fixing sleeve 403, the wire rope... Tie iron wire to the head of the main body 402, and disassemble all the strands at the head of the steel wire rope main body 402 into loose steel wire ropes 405. The disassembled loose steel wire ropes 405 are like a brush. Then bend each steel wire, clean the grease on the steel wire with a cleaning agent, and firmly pull the rope into the fixing sleeve 403. Use an oxygen cutting torch to fully heat the fixing sleeve 403, and pour the molten Babbitt alloy into the fixing sleeve 403 to fuse the loose steel wire ropes 405 into the fixing sleeve 403. It can be used after cooling.

[0022] Please see Figure 5 In this embodiment, the fixing component includes a limiting pin 501. A limiting pin 501 is disposed inside the hanging ear 404, and a spring 502 is disposed inside the limiting pin 501. A slider 503 is disposed on one side of the spring 502, and a stop block 504 is disposed on one side of the slider 503 to limit the movement of the limiting pin 501. A second groove is formed on the hanging ear 404, and the limiting pin 501 is movably connected to the inside of the hanging ear 404 through the second groove. The second groove on the hanging ear 404 provides a limiting effect when the limiting pin 501 moves within the groove. A third groove is formed on the limiting pin 501, and the slider 503 is slidably connected to the inside of the limiting pin 501 through the third groove. The third groove on the limiting pin 501 provides a limiting effect when the slider 503 slides within the groove.

[0023] During operation, one end of the wire rope body 402 is fixed to the head frame 2, and the other end is inserted into the fixing sleeve 403. A wire is tied to the head of the wire rope body 402. All strands at the head of the wire rope body 402 are then separated into loose wire ropes 405, resembling a brush. Each wire is then bent, and the grease on the wires is cleaned with a cleaning agent. The rope is then firmly pulled into the fixing sleeve 403. The fixing sleeve 403 is then thoroughly heated with an oxygen torch, and the molten Babbitt alloy is poured into the fixing sleeve 403, fusing the loose wire ropes 405 and the fixing sleeve 403 into one piece. After cooling, it can be used. During use, the stop block 50 is pressed... 4. The stop block 504 drives the slider 503 to slide, and the slider 503 compresses the spring 502, causing the stop block 504 to slide into the limit pin 501. Then the limit pin 501 is pulled out, and the lug 404 is placed on the outside of the closed cable joint. By pressing the stop block 504, the stop block 504 drives the slider 503 to slide, and the slider 503 compresses the spring 502, causing the stop block 504 to slide into the limit pin 501. Then the limit pin 501 is inserted into the slot 2 on the lug 404 and the inside of the closed cable joint. When the limit pin 501 is installed in place, the spring 502 drives the slider 503 to slide, and the slider 503 drives the stop block 504 to slide out, so that the limit pin 501 cannot be pulled out.

[0024] Through the above steps, one end of the wire rope body 402 is fixed to the head frame 2, and the other end is inserted into the fixing sleeve 403. Iron wire is tied at the head of the wire rope body 402. All the strands at the head of the wire rope body 402 are disassembled into loose wire ropes 405. The disassembled loose wire ropes 405 are like a brush. Each wire is then bent, and the grease on the wires is cleaned with a cleaning agent. The rope is then firmly pulled into the fixing sleeve 403. The fixing sleeve 403 is fully heated with an oxygen cutting torch, and the molten Babbitt alloy is poured into the fixing sleeve 403, fusing the loose wire ropes 405 and the fixing sleeve 403 into one piece. It can be used after cooling.
