Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to a mining steel strand discharge device. Background Technology

[0002] In mining construction, mining steel strands serve as crucial load-bearing and connecting components. Their single-spool lengths typically reach 1200 meters, and they are coiled and stored as spools. Due to the material properties and coiling state of the steel strands, significant elastic stress easily accumulates during the laying process. Traditional manual operations lack dedicated fixing and protective structures, making it easy for the entire spool of steel strand to scatter or spring up during cutting. This can not only cause deformation and damage to the steel strands but also easily lead to injuries from impacts, posing serious safety hazards. Furthermore, traditional operations require multiple people to coordinate in fixing the spools and pulling the steel strands, resulting in high manpower input. The steel strands are also prone to twisting and jamming during laying, leading to low laying efficiency and failing to meet the demands of high-efficiency operations on mining sites. Utility Model Content

[0005] Furthermore, the stress buffer discharge assembly includes an adjusting plate, a spring, a push plate, and a guide wheel; the adjusting plate is symmetrically positioned on both sides inside the cable outlet frame; two sets of springs are respectively provided at the upper and lower ends of the cable outlet frame; "["-shaped push plates are welded to the lower ends of the two sets of springs; the openings of the push plates are arranged opposite each other; a guide wheel is connected through the push plate by a round rod; the round rod is used in conjunction with a nut by passing through the adjusting holes and through holes on both sides of the adjusting plate and the push plate in sequence.

[0006] Furthermore, a groove is formed on one end surface of the support base; a protrusion is provided at the bottom of the baffle; the baffle is fixed in the groove by inserting the protrusion.

[0007] Furthermore, the positioning holes A are evenly distributed along the length of the guide rail, and the fixing pin is interference-fitted with both positioning holes A and positioning holes B.

[0008] Furthermore, the rubber buffer layer is fixed to the inner wall of the clamping part by adhesive bonding; the surface of the rubber buffer layer is provided with anti-slip texture.

[0009] Furthermore, the anti-slip pad is vertically connected to the support base via a screw.

[0010] Compared with the prior art, this utility model has the following advantages: This utility model features a plug-in fixing structure between the support base and the baffle, which is convenient to assemble and disassemble and provides a stable fixation, effectively limiting the axial movement of the steel strand spool. The cooperation between the guide rail and the slider allows for flexible adjustment of the gap between the adjusting claws, accommodating spools of different lengths. The interference fit between the fixing pin and the positioning hole ensures reliable positioning and prevents slider displacement during operation. The rubber buffer layer of the adjusting claw clamping part has anti-slip texture, which enhances clamping stability and buffers clamping pressure, preventing deformation and damage to the spool. The stress buffering and discharging component inside the wire outlet frame uses the elastic force of the spring to push the push plate and the guide wheel. It can automatically adapt to steel strands of different diameters. The guide wheel and the rounded transition structure of the outlet hole reduce the friction during steel strand discharge, avoiding jamming and twisting, while releasing the elastic stress accumulated during the discharge process. The anti-slip pad is connected to the bearing base through the screw, which is firmly installed and can enhance the stability of the device and prevent slippage during operation. The handle makes it easy to move and transfer the device. The overall structure does not require multiple people to operate, which greatly reduces labor costs. It not only eliminates the safety hazards of steel strands scattering and bouncing, but also significantly improves discharge efficiency, meeting the needs of efficient and safe operation on the mining site.

Detailed Implementation

[0013] The following will refer to the appendix in the embodiments of this utility model. Figure 1The technical solution of this utility model embodiment is clearly and completely described as follows: A mining steel strand discharge device includes a supporting base 1, and a guide rail 2 is symmetrically provided on the top of the supporting base 1; the guide rail 2 has a groove 202 and a plurality of positioning holes A201; a slider 3 is slidably connected in the groove 202; the slider 3 is provided with a positioning hole B302 adapted to the positioning hole A201; the positioning hole A201 and the positioning hole B302 are fixed by a fixing pin 301, the positioning holes A201 are evenly distributed along the length direction of the guide rail 2, and the fixing pin 301 and the positioning holes A201 and B302 are all interference fits. This fit method can ensure that the slider 3 Once positioned, it will not loosen, ensuring the stability of the spool and preventing spool displacement due to slider shifting during operation. An adjusting claw 4 is fixedly connected to the top of the slider 3. The adjusting claw 4 has an arc-shaped clamping part 402 at its end. A rubber buffer layer 401 is provided on the inner side of the arc-shaped clamping part 402. The rubber buffer layer 401 is fixed to the inner wall of the clamping part 402 by adhesive bonding, and its surface has anti-slip textures. The arc-shaped clamping part can fit snugly against the outer wall of the spool, increasing the contact area and further enhancing the anti-slip textures. The clamping friction prevents the spool from slipping during rotation, while the rubber material acts as a buffer to avoid deformation of the spool due to hard contact. A baffle 5 is fixed to one end of the support base 1, and a groove 101 is formed on the surface of one end of the support base 1. A protrusion is provided at the bottom of the baffle 5, and the baffle 5 is fixed in the groove 101 by inserting the protrusion. This insertion structure is simple to assemble and disassemble, facilitating adjustment of the baffle position according to the spool length or component maintenance. It also reliably restricts the axial movement of the spool, preventing it from slipping off the support base 1. The other end of the support base 1 is provided with a wire outlet frame 6; the wire outlet frame 6 is open on one side opposite to the baffle 5 and closed on the other side; a wire outlet hole 601 is provided in the middle of the closed side of the wire outlet frame 6; the inner side of the wire outlet hole 601 is provided with a rounded corner transition structure, which can avoid hard friction between the steel strand and the edge of the wire outlet hole, prevent wear on the surface of the steel strand, and extend its service life; a stress buffer discharge component is provided inside the open side of the wire outlet frame 6; the stress buffer discharge component is used in conjunction with the wire outlet hole 601; the bottom of the support base 1 is provided with an anti-slip pad 8, which is vertically connected to the support base 1 by a screw 9. The screw connection is firmly installed, which can prevent the anti-slip pad from falling off during use. The anti-slip pad can increase the friction between the device and the ground, improve the stability of the device when placed, and prevent the device from sliding during wire laying operations; the support base 1 is provided with handles 7 near the baffle 5 and the wire outlet frame 6 respectively. The handles 7 facilitate the operator to move the device and can be flexibly transferred to different work locations, improving the practicality of the device.

[0014] Specifically, the stress buffer discharge assembly includes an adjusting plate 602, a spring 603, a push plate 604, and a guide wheel 605; the adjusting plate 602 is symmetrically positioned on both sides inside the cable outlet frame 6; two sets of springs 603 are respectively provided at the upper and lower ends of the cable outlet frame 6; "["-shaped push plates 604 are respectively welded to the lower ends of the two sets of springs 603; the openings of the push plates 604 are arranged opposite each other; the guide wheel 605 is connected through the push plate 604 by a round rod 606; the round rod 606 is connected to the nut 608 through adjusting holes 607 and through holes 609 on both sides of the adjusting plate 602 and the push plate 604 in sequence. When used together, the nut 608 does not need to be tightly fixed when connected to the round rod 606, leaving a certain amount of room for movement to accommodate steel strands of different diameters and to act as a buffer. The spring 603 can provide a continuous elastic force, keeping the guide wheel 605 in contact with the surface of the steel strand, automatically adapting to steel strands of different diameters without the need for frequent manual adjustments. The guide wheel 605 can convert the sliding friction of the steel strand into rolling friction, greatly reducing discharge resistance and preventing the steel strand from jamming or twisting. At the same time, it releases the elastic stress accumulated during wire feeding, improving the smoothness of wire feeding, adapting to steel strands of special diameters, and enhancing the versatility of the component.

[0015] In use, first, according to the length of the steel strand spool to be laid, fix the baffle 5 in the corresponding groove 101 of the bearing base 1 by inserting the protrusion, ensuring that the baffle 5 can effectively limit one end of the spool; then pull out the fixing pin 301, slide the slider 3 along the slide groove 202 of the guide slide rail 2, adjust the distance between the two sets of adjusting claws 4 to match the length of the spool, and then insert the fixing pin 301 into the corresponding positioning hole A201 and positioning hole B302 to achieve a firm positioning of the slider 3; The steel strand spool is placed between two sets of adjusting claws 4, with one end of the spool in contact with the baffle 5. By adjusting the adjusting claws 4, the rubber buffer layer 401 of the clamping part 402 is made to fit tightly against the outer wall of the spool, using anti-slip texture to enhance clamping stability and prevent the spool from slipping or shifting when rotating. Then, according to the diameter of the steel strand, the position of the round rod 606 in the adjusting hole 607 and through hole 609 is adjusted by the nut 608, and the initial distance between the push plate 604 and the guide wheel 605 is finely adjusted. The elastic force pushes the push plate 604, causing the guide wheel 605 to automatically conform to the surface of the steel strand. One end of the steel strand passes between the two sets of guide wheels 605 and then through the outlet hole 601 of the outlet frame 6. The rounded transition structure of the outlet hole 601 works together with the guide wheel 605 to reduce friction and resistance when the steel strand is released. The operator can pull the free end of the steel strand to perform the wire release operation. During the wire release process, the guide wheel 605 rotates with the movement of the steel strand to avoid jamming or twisting. The spring 603 can buffer the tension fluctuation of the steel strand and release the accumulated elastic stress. When cutting the steel strand, the spool is firmly fixed by the adjusting claw 4 and the baffle 5, and the bearing base 1 is kept stable by the anti-slip pad 8, so the whole spool of steel strand will not scatter or bounce, ensuring the safety of operation. After the operation is completed, it can be transferred to the next work site through the handle 7 carrying device, without the need for multiple people to cooperate, which greatly reduces the labor input.

[0016] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
