Description

Technical Field

[0001] The utility model relates to the field of a wire-laying pulley maintenance device, in particular to an oil removal device for a wire-laying pulley. Background Art

[0002] At present, high-voltage transmission lines all use multi-split conductors, among which four-split, six-split, and eight-split conductors are more common. The specific construction method depends on the number of conductor splits and the conductor rules. Commonly used construction methods include "one pull two" and "one pull four". The common feature of these methods is that an even number of sub-conductors are pulled at the same time with one traction wire rope to achieve force balance. The number of pulleys of the matching wire-laying pulley is the number of sub-conductors plus 1, of which the middle pulley is the wire rope pulley and the other pulleys are the conductor pulleys.

[0003] Transmission lines in high altitude areas usually reduce corona discharge by increasing the conductor cross-sectional area. In areas with harsh terrain, increasing the conductor cross-sectional area will increase construction costs and construction difficulties. In principle, increasing the number of conductor splits is also an alternative method to increase the conductor cross-sectional area. Using a ten-split conductor in high altitude areas can solve the above problems.

[0004] In the construction of very cracked conductors in high altitude areas, the method of "one pull two" can be used five times, or the method of "one pull four" twice and "one pull two" once can be used. However, the construction efficiency of these methods is relatively low. The method of "one pull five" twice will greatly improve the construction efficiency.

[0005] When using the "one-pulling-five" pay-off pulley, the oil on the wire rope will be contaminated on the middle wheel after the wire rope passes through. When the traction board passes through the pay-off pulley, the middle wheel will become the conductor wheel, and the oil on the wheel will adhere to the conductor, thereby contaminating the conductor and easily causing corona discharge, which increases the danger. Utility Model Content

[0006] The technical problem to be solved and the technical task proposed by the utility model are to improve and perfect the existing technical solutions, and provide a wire-laying pulley oil removal device to achieve the purpose of cleaning the oil stains on the wire rope wheel of the wire-laying pulley and avoiding the oil stains from contaminating the wires passing through the middle wheel later. To this end, the utility model adopts the following technical solutions.

[0007] A degreasing device for a wire-laying pulley comprises a cleaning head, a bottom plate and an elastic support assembly, wherein the elastic support assembly is arranged between the cleaning head and the bottom plate, and the contour of the cleaning head matches the groove bottom of the middle wheel of the wire-laying pulley to be cleaned. The device is fixed to the horizontal plate at the bottom of the pulley frame through the bottom plate, and the cleaning head is aligned with the groove bottom of the embedded pulley and abuts against the groove bottom. When the pulley rotates, the cleaning head can be used to clean the oil stains at the bottom of the groove of the middle wheel of the wire-laying pulley. The elasticity of the elastic support assembly can realize the self-adaptation to the change of the groove bottom height when the middle wheel of the wire-laying pulley rotates, and the oil stains at the bottom of the groove of the middle wheel can be effectively cleaned to avoid oil stains from contaminating the wires that pass through the middle wheel later, reduce the corona discharge phenomenon of the wires, and improve safety.

[0008] As a preferred technical means: the elastic support assembly includes a support rod and a spring, the support rod is provided with a card plate, the spring is arranged between the card plate and the bottom plate and is sleeved on the support rod, and the outer diameter of the card plate is larger than the inner diameter of the spring. The elastic support of the support rod is achieved by the spring and the card plate. When the groove bottom position of the middle wheel of the wire-laying pulley drops, the cleaning head drops, causing the support rod to drop, and then the card plate drops, pressing the spring to compress the spring downward. When the groove bottom position of the middle wheel of the wire-laying pulley rises, the spring stretches upward and moves the card plate upward, thereby moving the support rod upward, and the support rod drives the cleaning head upward, so that the cleaning head always matches the groove bottom of the middle wheel, realizing the self-adaptation of the height position of the cleaning head, which can effectively compensate for the runout error of the middle wheel and effectively realize the cleaning of the oil stains at the groove bottom of the middle wheel.

[0009] As a preferred technical means: the bottom plate is provided with a guide cover, the middle of the upper end of the guide cover is provided with a guide hole that slides with the support rod, and the spring and the card are located inside the guide cover. The guide cover guides the movement of the support rod on the one hand, and limits the vertical movement of the card on the other hand. When the card moves up to contact the inner end surface of the top of the guide cover, it serves as the highest limit of the card, and can also prevent external oil, dust, etc. from polluting the spring.

[0010] As a preferred technical means: the bottom plate is a rectangular bottom plate, and the width of the left and right ends of the bottom plate is 30-50 mm larger than the left and right width of the guide cover. The size structure of the bottom plate is convenient for tying or bolting the two ends of the bottom plate to the horizontal plate at the bottom of the pulley frame.

[0011] As an optimal technical means: the left and right width of the guide cover is 8-20 mm smaller than the left and right width of the cleaning head, so as to avoid the guide cover from colliding with the rim of the middle wheel.

[0012] As a preferred technical means: the bottom plate and the guide cover are fastened by bolts, which effectively realizes a detachable connection structure between the bottom plate and the guide cover.

[0013] As a preferred technical means: a detachable connection structure is adopted between the support rod and the cleaning head. When the device is disassembled, the support rod and the spring can be removed by removing the cleaning head and the bottom plate. In addition, since the cleaning head is the main cleaning component and is easily damaged, the detachable structure facilitates the replacement and maintenance of the cleaning head.

[0014] As a preferred technical means: the distance between the upper end of the card plate and the lower end of the support rod is in the range of 9-12mm, the distance between the inner top of the guide cover and the upper end surface of the bottom plate is 4-7mm more than the distance between the upper end of the card plate and the lower end of the support rod, the lower end of the support rod is located above the bottom plate, and there is a separation structure between the lower end of the support rod and the bottom plate. This structure allows the guide cover to have enough vertical movement space for the support rod, which can effectively adapt to the vertical runout error of the compensation wheel, and the lower end of the support rod is a separation structure with no connection between the two, so that the support rod can move vertically under the action of the spring.

[0015] As a preferred technical means: the support rod is slidably matched with the auxiliary guide hole arranged in the middle of the bottom plate. By adding the auxiliary guide hole of the support rod on the bottom plate, the guiding effect is better.

[0016] Beneficial effect: The use of the wire-paying pulley oil removal device can reduce the oil stains on the middle wheel of the wire-paying pulley, reduce the contamination of the wire, thereby reducing the corona discharge phenomenon and improving safety. The elastic structure ensures that the vertical direction of the cleaning head is always matched with the groove bottom of the middle wheel, which is used to compensate for the runout error caused by the coaxiality difference when the middle wheel rotates, and the cleaning effect is better.

[0024] Example 1

[0025] like Figure 1 As shown, a degreasing device for a wire-laying pulley comprises a cleaning head 1, a bottom plate 2 and an elastic support assembly, wherein the elastic support assembly comprises a support rod 3 and a spring 4, wherein the support rod 3 is arranged between the cleaning head 1 and the bottom plate 2, a clamping plate 5 is arranged on the support rod 3, and the spring 4 is arranged between the clamping plate 5 and the bottom plate 2 and is sheathed on the support rod 3, wherein the outer diameter of the clamping plate 5 is greater than the inner diameter of the spring 4. The lower end surface of the clamping plate 5 is abutted against the upper end of the spring 4, the outline of the cleaning head 1 matches the bottom of the groove of the middle wheel 8 of the wire-laying pulley to be cleaned, and a guide cover 6 is provided on the bottom plate 2. A guide hole 601 is provided in the middle of the upper end of the guide cover 6 to slide with the support rod 3. The spring 4 and the clamping plate 5 are located inside the guide cover 6. The bottom plate 2 is a rectangular bottom plate 2. The width dimensions of the left and right ends of the bottom plate 2 are 40 mm larger than the left and right width dimensions of the guide cover 6, that is, 20 mm larger on one side, which is used to fix the bottom plate 2. The bottom plate 2 is fastened to the cross plate 7 at the bottom of the pulley frame by bolts, and can also be fixed to the cross plate 7 by binding with a cable tie, so that the oil removal device is installed and fixed on the wire-laying pulley.

[0026] The distance between the upper end of the clamping plate 5 and the lower end of the support rod 3 is 11 mm, the distance between the inner top of the guide cover 6 and the upper end surface of the bottom plate 2 is 15 mm, the lower end of the support rod 3 is located above the bottom plate 2, and there is a separation structure between the lower end of the support rod 3 and the bottom plate 2. This structure allows the guide cover 6 to have enough vertical movement space for the support rod 3, which can effectively adapt to the vertical runout error of the compensation wheel 8. The lower end of the support rod 3 and the bottom plate 2 are separated and are not connected, so that the support rod 3 can move vertically under the action of the spring 4.

[0027] The bottom plate 2 and the guide cover 6 are fastened by bolt connection, so that the detachable connection structure of the bottom plate 2 and the guide cover 6 is effectively realized.

[0028] A detachable connection structure is adopted between the support rod 3 and the cleaning head 1. When the device is disassembled, the support rod 3 and the spring 4 can be removed by removing the cleaning head 1 and the bottom plate 2. In addition, since the cleaning head 1 is the main cleaning component and is easily damaged, the detachable structure facilitates the replacement and maintenance of the cleaning head 1.

[0029] In order to prevent the guide cover 6 from colliding with the rim of the middle wheel 8, the left and right width of the guide cover 6 is 12 mm smaller than the left and right width of the cleaning head 1.

[0030] During assembly, first pass the support rod 3 with the clamping plate 5 from bottom to top through the guide hole 601 of the guide cover 6, connect and fix the cleaning head 1 at the upper end of the support rod 3, then insert the spring 4 into the support rod 3 from the bottom of the support rod 3, and then set the bottom plate 2, and fasten the bottom plate 2 to the guide cover 6 from bottom to top at the lower end of the guide cover 6 with bolts.

[0031] like Figure 2 , 3 As shown, when the oil removal device is installed, the bottom plate 2 is fastened to the horizontal plate 7 at the bottom of the pulley frame by bolts, and the bottom plate 2 can also be tied to the horizontal plate 7 at the bottom of the pulley frame by a strapping belt. The oil removal device is fixed on the pulley, and the fixed position is the lower position corresponding to the middle wheel 8 of the traction wire wheel.

[0032] When the traction wire wheel passes over the middle wheel 8 on the five-wheel wire-paying pulley, the middle wheel 8 of the wire-paying pulley rotates, and the cleaning head 1 of the oil removal device cleans the oil at the same time. During cleaning, when the bottom position of the groove of the middle wheel 8 of the wire-paying pulley drops, the cleaning head 1 drops, causing the support rod 3 to drop, and then the clamping plate 5 drops, pressing the spring 4 to compress the spring 4 downward. When the bottom position of the groove of the middle wheel 8 of the wire-paying pulley rises due to vertical jumping, the spring 4 extends upward and moves the clamping plate 5 upward, thereby making the support rod 3 upward, and the support rod 3 drives the cleaning head 1 upward, so that the cleaning head 1 is always matched with the bottom of the groove of the middle wheel 8, realizing the self-adaptation of the height position of the cleaning head 1, and effectively realizing the cleaning of the oil at the bottom of the groove of the middle wheel 8, which can effectively reduce the contamination of the subsequent passing wires, thereby reducing the corona discharge phenomenon.

[0033] On the one hand, the guide cover 6 guides the movement of the support rod 3, and on the other hand, it limits the vertical movement of the card plate 5. When the card plate 5 moves up to contact the inner end surface of the top of the guide cover 6, it serves as the upper limit of the card plate 5. It can also prevent the spring 4 from being contaminated by external oil, dust, etc.

[0034] The device is fixed on the transverse plate 7 at the bottom of the pulley frame through the base plate 2, and the cleaning head 1 is aligned with the bottom of the groove embedded in the middle wheel 8 of the pulley and is against the bottom of the groove. When the middle wheel 8 rotates, the cleaning head 1 can be used to clean the oil stains on the bottom of the groove of the wire-paying pulley. The elasticity of the elastic support component can be used to adapt to the change in the height of the bottom of the groove when the middle wheel 8 of the wire-paying pulley rotates, which can effectively compensate for the runout error of the middle wheel 8 and effectively clean the oil stains on the bottom of the groove of the middle wheel 8, thereby avoiding oil stains from contaminating subsequent wires and avoiding corona discharge on the wires, thereby improving safety.

[0035] By installing the oil removal device, the middle wheel 8 of the five-wheel pay-off pulley, i.e., the wire rope wheel, becomes the conductor wheel after the traction walking plate passes through the pulley, so that an odd number of conductors can be pulled at one time, which expands the methods and approaches of transmission line construction operations.

[0036] In this embodiment, the cleaning head 1 is a brush or a scraper.

[0037] Example 2

[0038] The difference from the above example is that in order to make the vertical movement of the support rod 3 more stable, Figure 4 As shown, the support rod 3 is slidably matched with the auxiliary guide hole 201 provided in the middle of the bottom plate 2. By adding the auxiliary guide hole 201 of the support rod 3 on the bottom plate 2, the guiding effect is better and the vertical movement of the support rod 3 is more stable.

[0039] above Figure 1-4 The oil removal device for a wire-laying pulley shown is a specific embodiment of the utility model, which has embodied the substantial characteristics and progress of the utility model. According to actual use needs and under the inspiration of the utility model, equivalent modifications can be made to its shape, structure, etc., which are all within the protection scope of this scheme.
