Paying-off device for power transmission line construction

Abstract

The utility model provides a power transmission line construction pay-off device which comprises a take-up reel, an active pay-off assembly is arranged on the front side of the upper end face of a bottom base table, and a damping assembly is arranged on the upper side of the interior of a first supporting stand plate. A low-speed motor drives a driving pay-off roller to rotate at a low speed through a driving shaft, and meanwhile, the driving shaft drives a driven pay-off roller to synchronously rotate in different directions through a driving gear, a driven gear and a driven shaft to drive a cable to actively move towards the front side for active pay-off; therefore, the external thread can drive the friction plate to move inwards together through the follow-up disc and the supporting seat to be in contact with the left end face of the supporting shaft rod, so that the rotation damping force of the supporting shaft rod is increased, and the situation that the supporting shaft rod continues to rotate under rotation inertia when the active pay-off assembly stops is avoided. And therefore, the cable wound on the annular side surface of the winding reel is loosened.

Description

Technical Field

[0001] The utility model relates to the technical field of transmission line construction and laying out, in particular to a transmission line construction and laying out device. Background Art

[0002] The construction of transmission lines mainly includes construction steps such as digging pits (holes), erecting poles, laying out wires, connecting conductors, tightening wires, and pulling wires. Transmission lines are divided into overhead transmission lines and cable lines, and laying out wires is an extremely important construction link in the construction of transmission lines. In the process of laying out transmission lines, a laying-out device is required to lay out the wires.

[0003] Publication No. "CN214527449U" provides a wire-reeling device for power transmission line construction, in which a card block inserted into a card slot can prevent a hanging ring from rotating, so that during the wire-reeling process, the left and right positions of the hanging ring can be fixed and cannot shake, so that the overall structure of the hanging ring and the rotating shaft is stable, and the wire drum can stably release the wire on this basis, which is beneficial for the workers to stably release the wire; such a structure can enable the rotating block and the movable plate to be moved to any position of the screw rod, which is beneficial for fixing hanging rings of different specifications and has strong adaptability.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the wire-reeling device is helpful for workers to release the wire stably, it does not have the ability to actively release the wire, resulting in the need to manually pull the cable on the wire drum to release the wire during actual use. When the cable is long, it will consume a lot of physical strength of the workers, and the wire drum in the wire-reeling device does not have rotational damping force when rotating, resulting in the inability to stop quickly during the release process. Therefore, during use, the cable wound on the wire drum is prone to become loose, and the practicality is poor. Utility Model Content

[0027] Embodiment 1:

[0028] A transmission line construction laying device comprises a first supporting station plate 1, a base 2, movable casters with foot brakes 3, a winding drum 5, a second supporting station plate 6 and a supporting shaft rod 7.

The winding drum 5 is installed on the annular side of the supporting shaft rod 7, and the winding drum 5 is convenient for winding up the external cable. The upper end surfaces of the first supporting station plate 1 and the second supporting station plate 6 are provided with limited slots 8, and the limited slots 8 match the supporting shaft rod 7.

[0029] An active pay-off assembly 4 is provided on the front side of the upper end face of the base platform 2, and the active pay-off assembly 4 is used to actively pay out the cable on the winding reel 5, so as to save the labor intensity of the staff. A damping assembly 9 is provided on the upper side of the interior of the first supporting station plate 1, and the damping assembly 9 is used to increase the rotational friction of the supporting shaft 7 so that the winding reel 5 has a certain damping force when rotating. A control panel is installed on the front side of the upper end face of the base platform 2, and the control panel is connected to the low-speed motor 42 through a wire. The control panel facilitates the staff to control the forward or reverse rotation of the low-speed motor 42. Since the internal detailed structure and working principle of the control panel are relatively mature technologies in the prior art, they will not be elaborated here.

[0030] The active pay-off assembly 4 includes a first support plate 41, a low-speed motor 42, a driven pay-off roller 43, a second support plate 44, an active pay-off roller 45, a driving shaft 46, a driven shaft 47, a driven gear 49 and a driving gear 411. The first support plate 41 is installed on the left side of the upper end surface of the bottom base 2, and the second support plate 44 is installed on the right side of the upper end surface of the bottom base 2. The first support plate 41 and the second support plate 44 can support the driving shaft 46, the driven shaft 47 and the low-speed motor 42. The low-speed motor 42 is installed on the upper side of the left end surface of the first support plate 41. The machine 42 can drive the driving shaft 46 to rotate at a low speed when working. The driving shaft 46 is installed on the right end of the low-speed motor 42. The driving shaft 46 and the active pay-off roller 45 are an integrated structure. The driving shaft 46 can support the active pay-off roller 45. The active pay-off roller 45 is arranged on the annular side of the driving shaft 46. A driven pay-off roller 43 is arranged directly below the active pay-off roller 45. The active pay-off roller 45 and the driven pay-off roller 43 have the same specifications. The active pay-off roller 45 and the driven pay-off roller 43 with the same specifications can push the interlaced cables to the front side for pay-off when they rotate synchronously in opposite directions.

[0031] A driving gear 411 is arranged on the right side of the annular side of the driving shaft 46, and the driving gear 411 is connected to the driving shaft 46 by welding. The driving gear 411 can drive the driven gear 49 to rotate. A driven gear 49 is meshed with the lower side of the annular side of the driving gear 411, and the driven gear 49 is connected to the driven shaft 47 by welding. The driven gear 49 can drive the driven shaft 47 to rotate. A driven shaft 47 is arranged inside the driven pay-off roller 43, and the driven shaft 47 and the driven pay-off roller 43 are an integrated structure. The driven shaft 47 can support the driven pay-off roller 43, and an inspection baffle 441 is installed on the right end face of the second support plate 44, and the inspection baffle 44 1 is a detachable structure, and the detachable inspection baffle 441 is convenient for the later staff to maintain the active gear 411 and the driven gear 49.

There are two groups of anti-skid silicone sleeves 48, and the two groups of anti-skid silicone sleeves 48 have the same specifications. The distance between the two groups of anti-skid silicone sleeves 48 and the cables on the winding reel 5 are interference fit. The two groups of anti-skid silicone sleeves 48 make the annular side surfaces of the active pay-off roller 45 and the driven pay-off roller 43 more anti-skid, so that the active pay-off roller 45 and the driven pay-off roller 43 that rotate synchronously in opposite directions drive the passing cables to the front side for active pay-off.

[0032] Embodiment 2:

[0033] On the basis of Example 1, in this embodiment, by rotating the external threaded rod 96 forwardly through the hand turntable 95, the external thread can drive the friction plate to move inward through the follower plate 961 and the support seat 92 to contact the left end surface of the support shaft 7, thereby increasing the rotational damping force of the support shaft 7, preventing the support shaft 7 from continuing to rotate under rotational inertia when the active pay-off assembly 4 stops, causing the cable wound on the annular side of the winding drum 5 to easily become loose.

[0034] The damping assembly 9 includes a friction plate 91, a support seat 92, an externally threaded rod 96 and an internally threaded through hole 97. An internally threaded through hole 97 is provided on the upper side of the left end surface of the first support station plate 1. An externally threaded rod 96 is installed inside the internally threaded through hole 97. The externally threaded rod 96 is connected to the hand turntable 95 and the follower plate 961 by welding. The internally threaded through hole 97 is meshed with the externally threaded rod 96. The internally threaded through hole 97 facilitates the externally threaded rod 96 to have the ability to move left and right when rotating forward or reverse. The right side of the externally threaded rod 96 is connected to the support seat 92. The support seat 9 2 can support the friction disc 91. The right end surface of the support seat 92 is equipped with the friction disc 91. The friction disc 91 is made of a brake pad. When the friction disc 91 made of a brake pad contacts the left end of the support shaft 7, the support shaft 7 will have a certain rotation resistance, so as to prevent the support shaft 7 from continuing to rotate under the rotation inertia when the active pay-off assembly 4 stops, causing the cable wound on the circular side of the winding drum 5 to become loose. The friction disc 91 is a detachable structure, which is convenient for the staff to replace it separately later.

[0035] The support base 92 is provided with limit rods 93 symmetrically on the upper and lower sides of the left end surface of the support base 92. The limit rods 93 are connected to the support base 92 by welding. The limit rods 93 prevent the support base 92 from rotating or shaking during the left and right movement. The ring side of the limit rod 93 is provided with digital scale lines. The digital scale lines are convenient for the staff to observe the left and right displacement distance of the limit rod 93, so as to judge the movement distance of the friction plate 91. The right end of the externally threaded rod 96 is provided with a follower plate 961, and a blocking ring 921 is installed in the middle position of the left end surface of the support base 92. The follower plate 961 and the blocking ring 921 facilitate the rotation of the externally threaded rod 96 to drive the support base 92 to move left and right. The left end of the externally threaded rod 96 is provided with a hand turntable 95. The hand turntable 95 is convenient for the staff to rotate the externally threaded rod 96 by hand. A locking screw 94 is installed on the upper side of the hand turntable 95, and the locking screw 94 is a butterfly screw. The locking screw 94 of the butterfly screw is not only convenient for the staff to tighten or loosen it by hand, so as to lock the hand turntable 95.

[0036] Working principle: During the construction of the transmission line, the staff first moves the device to the required position on the construction site, and then connects the input end of the control panel to the external power supply through a wire. When it is necessary to actively pay out the cable on the winding reel 5, first insert one end of the cable between the active pay-off roller 45 and the driven pay-off roller 43 (refer to Figure 1 ), and then the hand turntable 95 is rotated forward on the external threaded rod 96, so that the external thread of the forward rotation drives the support seat 92 to move inward through the follower plate 961, and the support seat 92 drives the friction plate to move inward together, so that the right end surface of the friction plate contacts the left end surface of the support shaft rod 7 (reference Figure 6), thereby increasing the rotation damping force of the support shaft 7, preventing the support shaft 7 from continuing to rotate under the rotation inertia when the active pay-off assembly 4 stops, causing the cable wound on the annular side of the winding drum 5 to become loose. During this process, as the friction disk 91 moves inward, the fitting force between the friction disk 91 and the support shaft 7 will gradually increase, and the rotation damping force of the support shaft 7 will also increase accordingly. Conversely, the rotation damping force of the support shaft 7 will decrease accordingly, so that the staff can adjust the rotation damping force of the support shaft 7 according to needs; after the adjustment is completed, the low-speed motor 42 can be started through the control panel, so that the low-speed motor drives the active pay-off roller 45 to rotate at a low speed through the active shaft 46, and the active shaft 46 will drive the active gear 411 to rotate together, so that the active gear 411 drives the driven pay-off roller 43 to rotate synchronously in opposite directions through the driven gear 49 and the driven shaft 47 (the rotation directions of the active pay-off roller 45 and the driven pay-off roller 43 are in Figure 4 91 , so that the active pay-off roller 45 and the driven pay-off roller 43 that rotate synchronously in opposite directions drive the cable to actively move forward to pay out the cable through the anti-slip silicone sleeve 48. When the cable is paid out to the required length, the low-speed motor 42 can be stopped. At this time, the rotating support shaft 7 will also stop rotating under the friction force of the friction disk 91, so as to ensure the tightness of the cable wound on the annular side of the winding drum 5. In the later use process, when the winding drum 5 needs to be disassembled, the staff first reverses the external threaded rod 96, so that the external threaded rod 96 can drive the friction disk 91 to separate outward through the support seat 92, so that the friction disk 91 is separated from the support shaft 7. At this time, the support shaft 7 can be lifted to separate it from the limiting slot 8, and then the fixing screw 51 is loosened with the help of an external wrench, and then the winding drum 5 can be disassembled and replaced.
