Description

Technical Field

[0001] This utility model relates to the field of cable winding technology, specifically a portable underground power transmission cable winding device. Background Technology

[0002] In the field of power construction, especially in mining environments, cable management is a crucial aspect. Traditional cable winding devices typically wind cables on flat ground. In this case, when the motor drives the winding drum to roll, it mainly overcomes the friction between the cable and the ground. Directly driving the winding drum with the motor does not cause it to bear a large load.

[0003] Due to the unique environment of mines, cables from underground need to be wound up on the surface using a reel. Directly driving the reel with a motor is insufficient to meet this requirement. This is because of the significant height difference between the surface and the underground; the cable must overcome friction and its own weight as it is pulled upwards for winding, placing a greater load on the motor. Furthermore, the depth of the mine means the motor would need to operate for extended periods, increasing the risk of overheating and damage, thus reducing its lifespan. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a portable underground power transmission cable winding device. Based on the traditional direct drive of the winding drum by a motor, the device adds a driving wheel and a driven wheel with a different transmission ratio, which can effectively reduce the load on the motor when driving the winding drum to wind the underground power transmission cable to the ground, thereby avoiding motor overheating and extending the service life of the motor.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A portable downhole power transmission cable winding device includes a base, on which a top seat that is parallel to each other and can be raised and lowered is mounted; on the top seat, two sets of winding supports are mounted, and a rolling winding drum is installed between the two sets of winding supports, in which the power transmission cable is wound.

[0007] Above the top seat is a drive support located next to the take-up support. A motor is mounted on the side of the drive support, and a drive wheel is concentrically connected to the shaft of the motor. A coupling is also concentrically connected to one side of the take-up drum, and a driven wheel is concentrically connected to the coupling.

[0008] The diameter of the driving wheel is smaller than that of the driven wheel, and the driving wheel and the driven wheel are connected by a transmission bar that is wound around both of them simultaneously.

[0009] By adopting the above scheme, the device adds a driving wheel and a driven wheel with a different transmission ratio to the traditional motor-driven winding drum, which can effectively reduce the load on the motor when driving the winding drum to wind up the underground power transmission cable to the ground, thereby avoiding motor overheating and extending the service life of the motor.

[0010] In a preferred embodiment of a portable downhole power transmission cable reel, both the driving wheel and the driven wheel are friction wheels, and the transmission strip is a belt strip, which achieves transmission between the driving wheel and the driven wheel through friction.

[0011] The above scheme employs friction transmission to achieve the drive wheel and driven wheel transmission, resulting in better noise reduction.

[0012] In a preferred embodiment of a portable downhole power transmission cable reel, both the driving wheel and the driven wheel are gears, and the transmission bar is a toothed chain. The toothed chain achieves transmission between the driving wheel and the driven wheel through tooth meshing.

[0013] In order to achieve the transmission between the driving wheel and the driven wheel, the above scheme adopts a gear meshing transmission method, which has better stability.

[0014] As a preferred embodiment of a portable downhole power transmission cable reel, a visible protective shell is also fixed between the reel support and the drive support. This protective shell completely covers the coupling, drive wheel, driven wheel, and transmission bar.

[0015] The above solution, by covering the driving and driven wheels with a protective shell to prevent accidental damage during rotation, also prevents stones and other objects from getting stuck in the driving or driven wheels.

[0016] In a preferred embodiment of a portable downhole power transmission cable winding device, an L-shaped clamp is fixed at the angle between the inner wall of the winding drum and the drum. The power transmission cable can be threaded through the inside of the L-shaped clamp. A vertically downward set screw is threaded through the top of the L-shaped clamp, and a set head is fixed at the end of the set screw.

[0017] The top surface is a frosted, rounded surface.

[0018] To ensure greater stability of the power transmission cable during winding, the above solution can be adopted. The end of the power transmission cable can be introduced into the L-shaped clamp, and the power transmission cable can be tightened by rotating the set screw and using the set head, thereby ensuring greater stability and reliability of the power transmission cable during winding.

[0019] In a preferred embodiment of a portable downhole power transmission cable reeling device, a lifting cylinder fixed on the base and a lifting rod fixed on the top are respectively installed at the four corners between the base and the top seat, wherein the lifting rod is located inside the lifting cylinder; multiple linearly arrayed insertion holes are opened through the lifting rod, and bolts inserted into the insertion holes are installed through the lifting cylinder, and butterfly head nuts are tightened on the bolts.

[0020] Using the above solution, in order to achieve height adjustment of the winding drum, the height of the lifting rod inside the lifting drum can be adjusted, and the two can be fixed with bolts and butterfly nuts, thus achieving height adjustment of the winding drum.

[0021] As a preferred embodiment of a portable downhole power transmission cable reel, a universal caster is fixed to the bottom of the base, and a push handle is fixed to one end of the top seat.

[0022] With the above solution, the device can be moved by holding the push handle, making it more flexible and convenient to use.

[0023] After adopting the above technical solution, the beneficial effects of this utility model are:

[0024] 1. Based on the traditional direct drive of the winding drum by the motor, this device adds a driving wheel and a driven wheel with a different transmission ratio, which can effectively reduce the load on the motor when driving the winding drum to wind up the underground power transmission cable to the ground, thereby avoiding motor overheating and extending the service life of the motor.

[0025] 2. To achieve the transmission between the driving wheel and the driven wheel, either friction transmission or gear transmission can be used; friction transmission offers better noise reduction, while gear transmission offers better stability.

[0026] 3. To prevent accidental damage to the driving and driven wheels during rotation, a protective shell is used to cover them, which also prevents stones and other objects from getting stuck in the driving or driven wheels.

[0027] 4. To ensure greater stability during cable winding, the end of the cable can be inserted into the L-shaped clamp. By rotating the set screw and using the set head, the cable can be tightened, thus ensuring greater stability and reliability during cable winding.

[0028] 5. To adjust the height of the winding drum, the height of the lifting rod inside the drum can be adjusted, and the two can be fixed with bolts and butterfly nuts.

[0029] 6. To facilitate the movement of the winding drum, the device can be moved by holding the push handle, making it more flexible and convenient to use. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] like Figures 1 to 4 As shown, a portable downhole power transmission cable winding device includes a base 1, on which a parallel and liftable top seat 2 is mounted; two sets of winding supports 3 are mounted on the top seat 2 by screws, and a rolling winding drum 4 is installed between the two sets of winding supports 3, with power transmission cable 5 wound inside the winding drum 4; a drive support 6 located next to the winding supports 3 is also mounted on the top seat 2 by screws, and a motor 7 is mounted on the side of the drive support 6 by screws, with a drive wheel 8 concentrically connected to the shaft of the motor 7 by screws; a coupling 9 is also concentrically connected to one side of the winding drum 4 by screws, with a driven wheel 10 concentrically connected to the coupling 9 by screws; the diameter of the drive wheel 8 is smaller than the diameter of the driven wheel 10, and the drive wheel 8 and the driven wheel 10 are connected by a transmission bar 11 wound around both of them simultaneously. Based on the traditional direct drive of the winding drum 4 by the motor 7, this device adds a drive wheel 8 and a driven wheel 10 to change the transmission ratio. This can effectively reduce the load on the motor 7 when driving the winding drum 4 to wind up the underground power transmission cable 5 to the ground, thereby avoiding overheating of the motor 7 and extending its service life.

[0042] like Figure 4 As shown, both the driving wheel 8 and the driven wheel 10 are friction wheels, and the transmission bar 11 is a belt. This belt achieves transmission between the driving wheel 8 and the driven wheel 10 through friction. Alternatively, both the driving wheel 8 and the driven wheel 10 are gears, and the transmission bar 11 is a toothed chain. This toothed chain achieves transmission between the driving wheel 8 and the driven wheel 10 through tooth meshing. To achieve transmission between the driving wheel 8 and the driven wheel 10, either friction transmission or tooth meshing transmission can be used. Friction transmission offers better noise reduction, while tooth meshing transmission offers better stability. Figure 4 It uses a gear meshing transmission method.

[0043] like Figure 3 As shown, a visible protective shell 12 is also fixed between the winding support 3 and the drive support 6 by screws. This protective shell 12 completely covers the coupling 9, the drive wheel 8, the driven wheel 10, and the transmission bar 11. To prevent accidental damage to the drive wheel 8 and the driven wheel 10 during rotation, the protective shell 12 is used to cover them, and it also prevents stones or other objects from getting stuck in the drive wheel 8 or the driven wheel 10.

[0044] like Figures 5 to 6 As shown, an L-shaped clamp 13 is fixed at the angle between the inner wall of the winding drum 4 and the drum itself. The inside of the L-shaped clamp 13 can be threaded through the power transmission cable 5. A vertically downward set screw 14 is threaded through the top of the L-shaped clamp 13, and a top head 15 is fixed at the end of the set screw 14. The surface of the top head 15 is a frosted arc surface. To ensure greater stability of the power transmission cable 5 during winding, the end of the power transmission cable 5 can be introduced into the L-shaped clamp 13. By rotating the set screw 14 and using the top head 15, the power transmission cable 5 can be tightened, thereby ensuring greater stability and reliability of the power transmission cable 5 during winding.

[0045] like Figures 7 to 8 As shown, at the four corners between the base 1 and the top seat 2, a lifting cylinder 16 welded and fixed to the base 1 and a lifting rod 17 welded and fixed to the top seat 2 are respectively installed, wherein the lifting rod 17 is located inside the lifting cylinder 16; multiple linearly arrayed insertion holes 18 are opened through the lifting rod 17, and bolts 19 inserted into the insertion holes 18 are installed through the lifting cylinder 16, with butterfly nuts 20 fastened to the bolts 19. In order to achieve height adjustment of the winding drum 4, the height of the lifting rod 17 inside the lifting cylinder 16 can be adjusted, and the bolts 19 and butterfly nuts 20 are used to fix the two, thus achieving height adjustment of the winding drum 4.

[0046] like Figure 7 As shown, a universal caster 21 is fixed to the bottom of the base 1 by screws, and a push handle 22 is welded to one end of the top of the top seat 2. In order to facilitate the movement of the winding drum 4, the device can be moved by holding the push handle 22, which makes it more flexible and convenient in use.

[0047] The working principle of this utility model:

[0048] Before application, the device can be moved to the wellhead on the ground by holding the push handle 22. Then, one end of the underground power transmission cable 5 is introduced into the L-shaped clamp 13. By rotating the top screw 14 and using the top head 15, the power transmission cable 5 is tightened, thereby ensuring that the power transmission cable 5 is more stable and reliable when winding.

[0049] In application, the motor 7 is started, and the motor 7 first drives the drive wheel 8 to rotate. Under the transmission of the transmission bar 11, the driven wheel 10 is then rotated, and under the action of the coupling 9, the winding drum 4 is finally rolled, thereby slowly winding the power transmission cable 5 upward. At this time, the transmission ratio of the motor 7 is changed by the drive wheel 8 and the driven wheel 10, which can effectively reduce the load on the motor 7 when driving the winding drum 4 to wind the underground power transmission cable 5 to the ground, thereby avoiding overheating of the motor 7 and extending the service life of the motor 7.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
