Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining cable winding and unwinding technology, and more specifically, to a cable winding and unwinding device for mining machinery. Background Technology
[0002] Cables are typically rope-like cables made up of several or groups of conductors twisted together. Each group of conductors is insulated from each other and twisted around a central core. The entire cable is covered with a highly insulating outer layer, giving it the characteristics of internal conductivity and external insulation. Mining machinery often requires cable routing during operation. Cable routing often requires the use of cable reeling and unloading mechanisms to facilitate quick and easy cable routing.
[0003] In an open-pit mine cable winding and unwinding mechanism with patent number CN215402372U, a sliding cable winding device is installed to prevent cable tangling and make the cable arrangement neater. However, during the winding process, the cable needs to be moved left and right to complete the winding. Mine cables are generally thick because power supply cables have large specifications and heavy weight per unit length. To move the cable left and right, a force in the left and right direction needs to be applied to the cable. When the cable moves left and right, friction is generated. As the number of turns of the cable coil increases, the bending angle of the cable will further increase, and the force in the left and right direction will be greater, which will increase the frequency of damage to the cable covering layer. Especially in winter, when the temperature is low, the cable hardness increases and its brittleness increases. Large-angle bending will further increase the degree of damage. Once the cable is scratched during winding and unwinding, it will cause leakage and create a safety hazard. Utility Model Content
[0004] To address the cable lifespan issues caused by wear and bending during the current cable winding and unwinding process, this invention provides a cable winding and unwinding device for mining machinery.
[0005] The embodiments of this utility model are implemented as follows:
[0006] A cable winding and unwinding device for mining machinery includes a support frame, a winding and unwinding mechanism for winding and unwinding cables and a traction frame, the traction frame having a traction block with a traction hole, the winding and unwinding mechanism being slidably mounted on the support frame along the axial direction of the cable coil, the support frame having a power component for driving the winding and unwinding mechanism to slide, and the traction block having an anti-wear ring embedded at the traction hole.
[0007] In this design, instead of using a traction block (i.e., the cable laying device in the prior art) to move and complete the cable winding and unwinding, the winding and unwinding mechanism moves to complete the winding and unwinding. The traction block plays a role in traction and positioning, which not only solves the problem of the cable becoming tangled and twisted, but also reduces the force applied to the outside of the cable in the lateral direction during winding, reduces the bending angle of the cable during the winding process, and reduces the friction pressure on the cable to a certain extent. It also avoids the problem of excessive bending of the cable due to changes in the cable position. At the same time, the addition of an anti-wear ring changes the friction coefficient in contact with the cable, so that when the traction hole cannot be aligned with the cable being wound and unwound in the ideal state, the wear of the cable cover layer can also be reduced.
[0008] In some technical solutions of this utility model, an adjustment frame is also included. Multiple adjustment hydraulic cylinders are provided between the adjustment frame and the support frame. The traction frame can be raised and lowered along the direction of gravity.
[0009] In this design, the friction between the cable and the inner wall of the traction block is further reduced, thus mitigating the degree of damage.
[0010] In some technical solutions of this utility model, the above-mentioned take-up and release mechanism includes a take-up and release frame that is slidably disposed on the support frame. The take-up and release frame is rotatably provided with a take-up and release shaft. The take-up and release shaft is sleeved with a sleeve. The take-up and release shaft is provided with take-up and release discs at both ends of the sleeve. The power component includes a main hydraulic cylinder disposed on the support frame. The telescopic end of the main hydraulic cylinder is connected to the take-up and release frame.
[0011] In this design, the hydraulic cylinder features high power density, smooth movement, good buffering performance, smooth and shock-free movement, convenient control, and strong adaptability, enabling it to better complete the movement of the take-up and take-down mechanism.
[0012] In some technical solutions of this utility model, the traction block is provided with a first mounting groove at the traction hole, and the anti-wear ring includes a rubber ring embedded in the first mounting groove, with a first sponge ring provided inside the rubber ring.
[0013] Using a rubber ring as a base and placing it in the first mounting groove can improve the stability of the anti-wear ring to a certain extent, prevent the anti-wear ring from being pulled out of the traction hole by the cable coil, and make it more stable.
[0014] In some technical solutions of this utility model, the traction block is provided with a second mounting groove at the traction hole, the anti-wear ring is a second sponge ring embedded in the second mounting groove, the traction block is provided with an inlet communicating with the mounting groove on its ring side, and the inlet is connected to a cleaning pipe.
[0015] In this design, it is preferable to use a second sponge ring with an inner diameter smaller than the outer diameter of the cable.
[0016] In some technical solutions of this utility model, the support frame is provided with a cleaning frame, the cleaning pipe is connected to a cleaning box provided on the cleaning frame, and the cleaning box is above the traction block.
[0017] This design utilizes gravity to drip the cleaning fluid in.
[0018] In some technical solutions of this utility model, the second mounting groove is a T-shaped groove.
[0019] The T-groove design can make the second sponge ring more stable to a certain extent.
[0020] In some technical solutions of this utility model, the traction block includes a traction mounting seat and a traction sub-seat that are detachably fastened to each other. The traction mounting seat is slidably disposed on the traction frame, and the inlet is disposed on the traction sub-seat.
[0021] This design facilitates the installation and replacement of the anti-wear ring.
[0022] In some technical solutions of this utility model, the above-mentioned traction mounting seat and the above-mentioned traction sub-seat are connected by bolts.
[0023] This design method is easy and simple to disassemble, and the cost is also low.
[0024] In some technical solutions of this utility model, a track is provided below the aforementioned adjustment frame.
[0025] This design makes it easier to move the cable retraction mechanism.
[0026] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects:
[0027] In this winding and unwinding mechanism, a power unit and a movable winding and unwinding mechanism are provided. The power unit drives the traction device to move left and right. With the help of the traction block, the position of the cable to be wound and unwound can be determined, and the moving body is switched to the winding and unwinding mechanism to complete the wiring. The traction block plays a role in traction and positioning, which not only satisfies the current phenomenon of the cable winding not being messy and tangled, but also reduces the force applied to the outside of the cable during the winding process, reduces the bending angle of the cable during the wiring process, reduces the friction pressure on the cable to a certain extent, and also avoids the problem of excessive bending of the cable due to the change of the cable position.
[0028] Adding anti-wear rings changes the coefficient of friction in contact with the cable, thus reducing wear on the cable cover when the traction hole cannot be aligned with the cable during take-up and take-down. Attached Figure Description

Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the various embodiments and features described below can be combined with each other.
[0041] Example
[0042] Please refer to Figures 1-5 A cable winding and unwinding device for mining machinery includes a support frame 1. The support frame 1 is provided with a winding and unwinding mechanism 2 for winding and unwinding cables and a traction frame 3. The traction frame 3 is provided with a traction block 4 having a traction hole 5. The winding and unwinding mechanism 2 is slidably disposed on the support frame 1 along the axial direction of the cable coil. The support frame 1 is provided with a power component for driving the winding and unwinding mechanism 2 to slide. The traction block 4 is provided with an anti-wear ring 7 embedded at the traction hole 5.
[0043] The principle of the take-up and release mechanism 2 is as follows: the support frame 1 is equipped with a slide rail, and the take-up and release mechanism 2 is equipped with a slide groove that matches the slide rail; the traction frame 3 is equipped with a linear motor 32 (the linear motor 32 is a device that directly converts electrical energy into linear motion mechanical energy without the need for an intermediate transmission mechanism. The linear motor 32 is a standard part, so it will not be described in detail), and the traction block 4 is located on the moving part of the linear motor 32.
[0044] When it is necessary to retract the cable, first pass the free end of the cable to be retracted through the traction hole 5 of the traction block 4, and then wind and fix the cable onto the take-up and release mechanism 2 (the point where the cable to be retracted is tangent to the cable coil on the take-up and release mechanism 2 is point B1). At this time, the end of the cable to be retracted, that is, the connection point between the cable and the mechanical connection, is point A1. When it is necessary to release the cable, pass the free end of the cable on the take-up and release rack 8 (the point where the cable to be released is tangent to the cable coil on the take-up and release mechanism 2 is point B2) through the traction hole 5 of the traction block 4, and connect it to the required mechanical end (this connection point is A2). After the cable connection is completed, first adjust the cable B point (point B1 when retracting the cable, point B2 when releasing the cable) in the take-up and release mechanism 2 to the other end of the cable to be retracted or released. The lateral position of endpoint A (point A1 when retracting the cable, point A2 when releasing the cable), i.e., adjusting the position of the cable on the horizontal plane, requires adjusting the positions of traction block 4 (center point C of traction hole 5) and retraction / release mechanism 2. The power unit is started first, and the position of retraction / release mechanism 2 is adjusted so that the point (point B) where the cable coil in retraction / release mechanism 2 is tangent to the retracted or released cable intersects with the center point (point C) of traction hole 5. Then, retraction / release mechanism 2 and traction block 4 are adjusted synchronously to make the cable passing through traction hole 5 as straight as possible on the horizontal plane (i.e., points A, B, and C are in a straight line in the horizontal direction). That is, the degree of bending of the cable is reduced in the horizontal position so that the cable does not bend to the left or right of traction block 4. During the adjustment process, it may be necessary to adjust the overall position of the cable winding and unwinding mechanism 2. If the application position of the cable to be wound and unwound changes (i.e., changes at point A) and the change lasts for a long time, the positions of the winding and unwinding mechanism 2 (point B) and the traction block 4 (point C) can be adjusted simultaneously. Of course, if the fluctuation is small or the change time is short, no adjustment is necessary.
[0045] Once the horizontal adjustment is complete, the take-up and unwind mechanism 2 begins to take up and unwind the cable. During this process, the power component operates at a constant speed, replacing the traditional movement of the traction block 4. The take-up and unwind mechanism 2 slides back and forth along the cable coil axis, coordinating with the speed of the take-up and unwind to complete the winding process. During winding, the goal is to keep the cable to be taken up and unwound as straight as possible in the horizontal direction, reducing wear between the cable and the left and right sides of the traction block 4. It is worth noting that the take-up and unwind mechanism 2 preferably includes a central processing unit (the final execution unit for information processing and program execution). The power component and drive motor 31 are electrically connected to the central processing unit, allowing for better control of the reciprocating position and speed of the power component, and facilitating responses to frequent changes in the cable's application location (i.e., the cable's usage location) and the traction hole 5.
[0046] This design, compared to the existing technology that uses the traction block 4 (i.e., the cable laying device in the existing technology) to complete the cable winding and laying, replaces it with the winding and laying mechanism 2 to complete the wiring. The traction block 4 plays a role in traction and positioning, which not only solves the problem of the cable winding not becoming tangled, but also reduces the force applied to the left and right sides of the cable during the winding process, reduces the left and right bending angle of the cable during the laying process, and reduces the friction pressure on the cable to a certain extent. It also avoids the problem of excessive bending of the cable due to changes in the position of the cable. At the same time, the addition of the anti-wear ring 7 changes the friction coefficient in contact with the cable, so that when the traction hole 5 cannot be aligned with the cable winding and laying in the ideal state, the wear of the cable cover layer can also be reduced.
[0047] As a preferred embodiment, it also includes an adjustment frame 26, and a plurality of adjustment hydraulic cylinders 25 are provided between the adjustment frame 26 and the support frame 1, so that the traction frame 3 can be raised and lowered along the direction of gravity.
[0048] The hydraulic cylinders 25 are preferably four in number and can be raised and lowered independently; the traction frame 3 includes a crossbeam 27 and two bases 28, with a drive assembly between each base 28 and the crossbeam 27. The two drive assemblies are used to drive the crossbeam 27 to move radially along the cable coil. A linear motor 32 (a linear motor 32 is a device that directly converts electrical energy into linear motion mechanical energy without an intermediate transmission mechanism; the linear motor 32 is a standard part and will not be described in detail) is installed on the moving part of the linear motor 32. The first structure of the drive assembly is: two drive assemblies are connected... The two drive components are identical in structure. The drive assembly is a telescopic rod (using a spring-loaded snap-on type: the rod is released or locked by pressing the snap, allowing for rapid adjustment and suitable for scenarios requiring frequent extension and retraction) connected to the base 28. The two ends of the crossbeam 27 are located at the uppermost telescopic end of the telescopic rod. A second structure for the drive assembly is as follows: both drive groups have the same structure, including a load-bearing frame 29 mounted on the base 28. The load-bearing frame 29 is rotatably equipped with a drive screw 30, which is connected to a drive motor 31 mounted on the load-bearing frame 29. The drive screw 30 has drive blocks, and the two ends of the crossbeam 27 are respectively connected to two drive blocks. In this method, the second structure is used because the two drive components in this structure can be connected to a central processing unit, resulting in more precise control.
[0049] In this design, the adjusting hydraulic cylinder 25 can level the position of the take-up and release mechanism 2, making it more suitable for the working environment of mines. When the take-up and release mechanism 2 needs to take up and release the cable and has completed the horizontal leveling, the drive component works to adjust the height of the traction hole 5 in the longitudinal direction, so that the center point (point C) of the traction hole 5 is the same as the height of the point (point B) where the cable coil in the take-up or release mechanism 2 is tangent to the cable being taken up or released, in the direction of gravity. Then, the four adjusting hydraulic cylinders 25 rise and fall synchronously, so that points A, B and C are at the same height, completing the adjustment in the longitudinal direction, so that points A, B and C are at the same height in the direction of gravity (forming a straight line). At this time, the cable is close to a straight line in both the horizontal and vertical directions, that is, the friction between the cable and the inner wall of the traction block 4 is further reduced, and the bending between the cable and the upper and lower walls of the traction block 4 is smaller or even non-existent, which further reduces the damage to the cable during the take-up and release process. After one layer of cable coil is wound (or one layer of cable is released), the drive assembly operates, causing the traction block 4 to move (when retracting the cable, the traction block 4 needs to move downwards because the cable coil becomes larger; when releasing the cable, the traction block 4 moves upwards because the cable coil becomes larger). The moving distance of the traction block 4 is equal to the diameter of the cable. At the same time, the four adjusting hydraulic cylinders 25 move synchronously, in the opposite direction to the moving direction of the traction block 4, and the moving distance is the same as the moving distance of the traction block 4. This ensures that the cable remains relatively straight in the longitudinal direction, keeping the friction within a relatively small range.
[0050] In a preferred embodiment, the above-mentioned take-up and release mechanism 2 includes a take-up and release frame 8 slidably disposed on the support frame 1. The take-up and release frame 8 is rotatably provided with a take-up and release shaft 9. The take-up and release shaft 9 is sleeved with a sleeve 11. The take-up and release shaft 9 is provided with take-up and release discs 10 at both ends of the sleeve 11. The power component includes a main hydraulic cylinder 6 disposed on the support frame 1. The telescopic end of the main hydraulic cylinder 6 is connected to the take-up and release frame 8.
[0051] In the above embodiment, the take-up and release frame 8 is provided with a slide groove adapted to the slide rail; the hydraulic cylinder is the actuator in the hydraulic system, which converts hydraulic energy (pressure energy of liquid) into mechanical energy (linear reciprocating motion or oscillation) to drive the load to achieve specific actions; the take-up and release frame 8 is provided with a main motor (if the device is equipped with a central processing unit, the main motor is preferably a servo motor and is electrically connected to the central processing unit), and any end of the take-up and release shaft 9 passes through the corresponding take-up and release plate 10 and is connected to the output end of the main motor; in this design, the main hydraulic cylinder 6 has the characteristics of high power density, smooth movement, good buffering performance, smooth and shock-free movement, convenient control and strong adaptability, and can better complete the movement of the take-up and release mechanism 2.
[0052] In a preferred embodiment, the traction block 4 is provided with a first mounting groove 12 at the traction hole 5, and the anti-wear ring 7 includes a rubber ring 13 embedded in the first mounting groove 12, and a first sponge ring 14 is provided on the inner side of the rubber ring 13.
[0053] In the above embodiment, a rubber ring 13 is selected as the base and placed in the first mounting groove 12. Since the rubber material is harder than the sponge, it can improve the stability of the anti-wear ring 7 while ensuring cushioning, and prevent the anti-wear ring 7 from being carried out of the traction hole 5 by the cable coil, making the installation more stable. At the same time, because the rubber material is dense and the hardness is adjustable, its coefficient of friction is generally higher than that of the sponge. Therefore, this design combines the characteristics of stability and low friction.
[0054] In a preferred embodiment, the traction block 4 is provided with a second mounting groove 15 at the traction hole 5, the anti-wear ring 7 is a second sponge ring 16 embedded in the second mounting groove 15, and the traction block 4 is provided with an inlet 17 communicating with the mounting groove on its circumferential side, and the inlet 17 is connected to a cleaning pipe 18.
[0055] In the above embodiment, personnel can introduce cleaning liquid into the second mounting groove 15 through the cleaning pipe 18. Cleaning agent can be added to the cleaning liquid as needed. (Personnel can introduce the cleaning liquid based on the energization status of the cable. This design is suitable when the cable is not energized. CRC02150 is preferred as the cleaning agent; it is fast-drying, non-conductive, and non-corrosive, suitable for high-voltage cable semiconductor cores. If there is no energization and the cable will be cleaned later, clean water can be used to wipe away dust from the cable surface.) It is worth noting that in this design, the inner diameter of the second sponge ring 16 is preferably smaller than the outer diameter of the cable to achieve the desired cleaning effect.
[0056] In a preferred embodiment, the support frame 1 is provided with a cleaning frame 19, and the cleaning pipe 18 is connected to a cleaning box 20 provided on the cleaning frame 19. The cleaning box 20 is above the traction block 4.
[0057] In the above embodiment, the cleaning pipe 18 includes a valve. When cleaning fluid needs to be dripped in, the valve can be opened, and the liquid in the cleaning tank 20 will enter the second mounting groove 15 of the traction block 4 through the cleaning pipe 18 under the action of gravity. This design utilizes gravity to complete the dripping of cleaning fluid. It is worth noting that personnel need to pay attention to the length of the cleaning pipe 18. Preferably, a quick connector (a connector that can connect or disconnect the pipeline without tools, which is existing technology and will not be described in detail) is set between the inlet 17 and the cleaning pipe 18. When cleaning of the cable is not required, the cleaning pipe 18 can be quickly and directly removed.
[0058] In a preferred embodiment, the second mounting groove 15 is a T-shaped groove 21.
[0059] In the above embodiment, the design of the T-groove 21 can make the second sponge ring 16 more stable to a certain extent.
[0060] In a preferred embodiment, the traction block 4 includes a traction mounting seat 22 and a traction sub-seat 23 that are detachably and interlocked with each other. The traction mounting seat 22 is slidably disposed on the traction frame 3, and the inlet 17 is disposed on the traction sub-seat 23.
[0061] In the above embodiment, the nut is set on the traction mounting seat 22, the traction mounting seat 22 and the traction sub-seat 23 are interlocked, and locking grooves are provided on the outer side of the traction mounting seat 22 and the outer side of the traction sub-seat 23, which are fixed and locked by stainless steel clamps; this design facilitates the installation and replacement of the anti-wear ring 7.
[0062] In a preferred embodiment, the traction mounting base 22 and the traction sub-base 23 are connected by bolts 24.
[0063] In the above embodiment, both ends of the traction mounting base 22 are provided with first connecting plates, and both ends of the traction sub-base 23 are provided with second connecting plates in cooperation with the two first connecting plates. Bolts 24 pass through the first connecting plates and the corresponding second connecting plates in sequence and are then connected to lock nuts. Preferably, the traction mounting base 22 and the traction sub-base 23 are connected by multiple bolts 24. This design is convenient and simple to disassemble and has a low cost.
[0064] As a preferred embodiment, the adjustment frame 26 is provided with a track 34 below it.
[0065] The bottom of the adjusting frame 26 can be equipped with wheels or tracks 34 (tracks 34 are flexible chains driven by the drive wheel and surrounding the drive wheel, road wheel, idler wheel and support wheel). Tracks 34 are more suitable for movement outside the mine than wheels, but wheels are more suitable for entering the mine. Of course, if the position of the cable winding and unwinding is fixed, neither wheels nor tracks 34 need to be used. This design makes it easier for the cable winding and unwinding mechanism 2 to move.
[0066] In summary, the embodiments of this utility model provide a cable winding and unwinding device for mining machinery, which solves the problem of cable tangling that easily occurs when the traditional winding and unwinding mechanism 2 winds the cable. This ensures that the wound cable remains neat while also reducing the wear on the cable caused by the traction block 4 moving the cable, thus avoiding rapid wear of the cable cover layer.
