Description

Technical Field

[0001] This utility model belongs to the field of coal mining and tunneling machinery technology, specifically a cable winding device for coal mining and tunneling. Background Technology

[0002] Coal mining tunneling is the core link in coal mining, which refers to the excavation of roadways in the coal seam through mechanical means or blasting to create space for coal mining and transportation. It is mainly divided into preparation roadway excavation and mining roadway excavation. Modern tunneling technologies include fully mechanized tunneling and shield tunneling, which rely on equipment such as tunneling machines and anchor drilling rigs, taking into account both efficiency and safety.

[0003] In coal mining and tunneling, it is often necessary to lay or rewind cables. However, because the cables used in coal mining and tunneling have a large diameter and are heavy, the elastic rebound of the cable itself after rewinding will gradually destroy the initial winding tension, resulting in gaps between cable layers, which in turn leads to loosening and slippage problems. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a cable winding device for coal mining and tunneling, which solves the problem that after winding, the cable will gradually lose its initial winding tension due to its own elastic rebound, resulting in gaps between cable layers, which in turn leads to loosening and slippage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable winding device for coal mining and tunneling, comprising a base, a caster wheel installed on one side of the base, a support leg connected to the other side of the base, a handle slidably connected to the base via the support leg, a motor fixedly installed on the base, a main baffle connected to one side of the base, a secondary baffle connected to the other side of the base, a winding roller rotatably connected to the main baffle and the secondary baffle via bearings, and an adjustment groove provided on the secondary baffle;

[0006] A connecting ring is rotatably connected inside the sub-baffle. An adjusting bolt is connected to the connecting ring. Multiple inclined grooves are centrally symmetrically opened on the connecting ring. A clamping roller is slidably connected inside the inclined groove. A sliding groove is opened at one end of the take-up roller. A fixed block is connected to one side of the take-up roller located in the sliding groove. A screw is threadedly connected to the take-up roller. A movable block is rotatably connected to one end of the screw.

[0007] As a further embodiment of this utility model: a patterned cap is threaded onto the adjusting bolt, the adjusting bolt slides within the adjusting groove, and a rubber pad is connected within the adjusting groove.

[0008] As a further embodiment of this utility model: the motor output shaft is connected to the take-up roller, the movable block slides in the groove and contacts the groove wall, and the fixed block is provided with a V-shaped groove on the side opposite to the movable block.

[0009] As a further embodiment of this utility model: multiple limiting grooves are provided on the main baffle in a centrally symmetrical manner, and one end of the pressing roller is connected to a limiting block, which slides in the limiting groove and fits against the groove wall.

[0010] As a further embodiment of this utility model: the support leg is provided with a cavity, and a pointed cone is connected to one end of the handle that extends into the cavity, and a retaining ring is connected to the pointed cone.

[0011] As a further embodiment of this utility model: the auxiliary baffle is provided with multiple guide grooves, the end of the pressing roller that slides in the inclined groove is T-shaped, and the pressing roller slides in the guide groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This cable winding device for coal mining and tunneling, by setting up adjusting bolts, adjusting grooves, connecting rings, inclined grooves and clamping rollers, when the motor rotates the winding roller to complete the cable winding, pushes the adjusting bolt to slide in the adjusting groove, causing the connecting ring to rotate in the auxiliary baffle. During this process, the inclined groove wall pushes the clamping roller, causing multiple clamping rollers to move synchronously along the guide groove towards the winding roller, thereby pressing and fixing the wound cable with multiple clamping rollers. Then, the pattern cap is turned to make the pattern cap press and adhere tightly to the rubber pad, thereby fixing the connecting ring, thus preventing the wound cable from becoming loose or shifting due to loss of tension.

[0014] 2. This cable winding device for coal mining and tunneling consists of a screw, a movable block, a fixed block, a chute, a cone, and support legs. By turning the screw, the movable block moves within the chute, which in turn clamps and secures the cable end to the fixed block. This prevents the cable from slipping or spinning freely during winding due to an unsecured or loosely secured cable end. The base can be lifted at an angle by the handle and moved using the casters. The operation is simple. When the support legs contact the ground, pressing down on the handle causes the cone to insert into the soil, thus securing the cable in soft ground.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1-5 As shown, this utility model provides a technical solution: a cable winding device for coal mining and tunneling, including a base 1, a caster wheel 2 installed on one side below the base 1, and a support leg 3 connected to the other side below the base 1. The support leg 3 has a cavity, and a handle 4 is connected to a pointed cone 22 at one end of the handle 4 that extends into the cavity. A retaining ring 23 is connected to the pointed cone 22. By inserting the pointed cone 22 into the soft ground to form an anchoring effect, the base 1 is stably fixed on the soft geological ground. The retaining ring 23 on the pointed cone 22 can prevent the pointed cone 22 from moving down too much and prevent the handle 4 from falling off the support leg 3.

[0023] The base 1 is slidably connected to the handle 4 via the support leg 3. The motor 5 is fixedly installed on the base 1. The main baffle 6 is connected to one side of the base 1. Multiple limiting grooves 20 are provided on the main baffle 6 in a centrally symmetrical manner. One end of the pressing roller 13 is connected to the limiting block 21. The limiting block 21 slides in the limiting groove 20 and fits against the groove wall. Through the sliding cooperation between the limiting block 21 and the limiting groove 20, the limiting groove 20 can restrict the pressing roller 13 and prevent the pressing roller 13 from rotating.

[0024] A secondary baffle 7 is connected to the other side of the base 1. Multiple guide grooves 24 are provided on the secondary baffle 7. The end of the pressing roller 13 that slides in the inclined groove 12 is T-shaped and slides in the guide groove 24. The movement of the pressing roller 13 is guided by the guide groove 24 to prevent the pressing roller 13 from tilting when it moves.

[0025] The main baffle 6 and the auxiliary baffle 7 are rotatably connected to the take-up roller 8 via bearings. The output shaft of the motor 5 is connected to the take-up roller 8. The movable block 17 slides in the slide groove 14 and contacts the groove wall. The fixed block 15 is provided with a V-groove on the side opposite to the movable block 17. The fixed block 15 and the V-groove on the movable block 17 can achieve stable clamping of the cable end. The slide groove 14 can restrict the movable block 17 and prevent the movable block 17 from rotating and tilting when moving.

[0026] The auxiliary baffle 7 has an adjustment groove 9, and a connecting ring 10 is rotatably connected inside the auxiliary baffle 7. An adjustment bolt 11 is connected to the connecting ring 10, and a patterned cap 18 is threaded onto the adjustment bolt 11. The adjustment bolt 11 slides in the adjustment groove 9, and a rubber pad 19 is connected inside the adjustment groove 9. Multiple inclined grooves 12 are centrally symmetrically opened on the connecting ring 10, and a clamping roller 13 is slidably connected inside the inclined groove 12. A sliding groove 14 is opened at one end of the winding roller 8, and a fixing block 15 is connected to one side of the sliding groove 14. A screw 16 is threaded onto the winding roller 8, and a movable block 17 is rotatably connected to one end of the screw 16. By turning the patterned cap 18, the patterned cap 18 is forced to squeeze the rubber pad 19 and come into contact with the rubber pad 19, thereby increasing the friction between the patterned cap 18 and the adjustment groove 9 and locking the position of the adjustment bolt 11.

[0027] The working principle of this utility model is as follows:

[0028] By turning the screw 16, the movable block 17 is moved within the slide groove 14, thereby clamping and fixing the cable end with the fixed block 15 and the movable block 17. Then, by starting the motor 5, the take-up roller 8 is rotated, causing the cable to wind onto the take-up roller 8. After that, by pushing the adjusting bolt 11 to slide within the adjusting groove 9, the connecting ring 10 is rotated within the auxiliary baffle 7. At this time, the groove wall of the inclined groove 12 pushes against the clamping roller 13, causing multiple clamping rollers 13 to move along the guide groove 24 toward the take-up roller 8, thereby pressing and fixing the wound cable with multiple clamping rollers 13. Then, the pattern cap 18 is turned to press and adhere to the rubber pad 19, thereby fixing the connecting ring 10 to prevent loosening or movement after winding.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
