Abstract
Description
Technical Field
[0001] This utility model relates to the field of grounding pulleys, and more specifically, to a grounding pulley with an adjustable structure. Background Technology
[0002] Grounding pulleys are used to eliminate electrostatic induction generated on the laid conductors or ground wires during tension stringing. Specifically, in the laying of conductors on long tension sections of transmission lines, the conductors are suspended and insulated from the ground as they pass through each tower. However, during the installation of spacers on multi-split conductors in high-voltage lines or during stringing operations, induced static electricity may occur on the conductors when they cross energized equipment or adjacent parallel lines. If this induced static electricity reaches a certain intensity, it can potentially cause injury. Therefore, grounding pulleys are used to eliminate static electricity generated on the laid conductors or ground wires during tension stringing.
[0003] However, existing grounding trolleys generally only have three-point positioning, with two wheels on top and one adjusting wheel on the bottom, which can be fixed to the outside of the conductor and move along the conductor. However, since the bottom of the grounding trolley needs to be connected to the ground, the bottom is easily affected by wind and swings. This means that when the grounding trolley swings, it may fall off because there is little protective structure on the front, resulting in poor stability. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a grounding trolley with an adjustable structure.
[0005] To solve the above problems, the present invention adopts the following technical solution.
[0006] A grounding trolley with an adjustable structure includes a T-shaped plate. Two upper pulleys are rotatably connected to the horizontal section of the T-shaped plate. A horizontal block is vertically mounted on the T-shaped plate. A clamping element is mounted on the horizontal block, and a lower pulley is mounted on the clamping element. An I-beam slides vertically on the horizontal section of the T-shaped plate. The bottom end of the I-beam extends below the horizontal section of the T-shaped plate. Anti-disengagement hooks are fixedly connected to both ends of the bottom of the I-beam. A positioning block is rotatably connected to the horizontal section of the I-beam, and the positioning block abuts and engages with the top of the T-shaped plate.
[0007] As a further description of the above technical solution: the top of the T-shaped plate is provided with a strip-shaped slot, and the bottom edge of the positioning block is inserted into the interior of the strip-shaped slot.
[0008] As a further description of the above technical solution: a first spring is fitted on each of the two vertical sections of the I-beam frame, the bottom end of the first spring is fixedly connected to the outer side of the vertical section of the I-beam frame, and the top end of the first spring is fixedly connected to the bottom of the horizontal section of the T-shaped plate.
[0009] As a further description of the above technical solution: the clamping component includes a threaded rod, a sliding frame, and a second spring. The top end of the threaded rod extends through to the top of the horizontal block and is slidably connected thereto. The top end of the threaded rod is rotatably connected to the sliding frame. One side of the back of the sliding frame is slidably connected to the front of the T-shaped plate. The lower pulley is rotatably mounted on the sliding frame. The second spring is sleeved on the outside of the threaded rod. The bottom end of the second spring is fixedly connected to the horizontal block, and the top end of the second spring is fixedly connected to the sliding frame.
[0010] As a further description of the above technical solution: a toggle ring is fixedly connected to the bottom end of the threaded rod.
[0011] As a further description of the above technical solution: the front side of the horizontal section of the T-shaped plate is rotatably connected to two auxiliary rollers, which are located directly above the sliding roller.
[0012] Compared with existing technologies, the advantages of this utility model are:
[0013] This solution uses a clamping component to drive the lower roller adjustment, which facilitates the installation and removal of cables by the device. Furthermore, the anti-disengagement hook on the I-beam frame, in conjunction with the positioning block, provides multi-directional protection for the cable. This allows the device to achieve all-round limiting of the cable, ensuring stable connection, while not affecting the device's position adjustment along the cable. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;
[0021] Please see Figures 1-4 In this utility model, a grounding trolley with an adjustable structure includes a T-shaped plate 1. Two upper pulleys 2 are rotatably connected to the horizontal section of the T-shaped plate 1. A horizontal block 3 is vertically installed on the T-shaped plate 1. A clamping member 4 is installed on the horizontal block 3. A lower pulley 5 is installed on the clamping member 4. An I-beam 6 slides vertically on the horizontal section of the T-shaped plate 1. The bottom end of the I-beam 6 extends below the horizontal section of the T-shaped plate 1. Anti-disengagement hooks 7 are fixedly connected to both ends of the bottom of the I-beam 6. A positioning block 8 is rotatably connected to the horizontal section of the I-beam 6. The positioning block 8 is mated and cooperates with the top of the T-shaped plate 1.
[0022] In this invention, a T-shaped plate 1 serves as the main body of the device. During use, two upper pulleys 2 are vertically hung on the conductor. Then, the bottom clamping member 4 is rotated to move the lower pulley 5 upwards, contacting the bottom of the conductor and achieving three-point positioning. This stabilizes the T-shaped plate 1 on the conductor and facilitates position adjustment along the conductor. Then, the I-beam 6 is pulled upwards, causing two anti-detachment hooks 7 to move to the front side of the conductor, working in conjunction with the T-shaped plate 1 to fully limit the conductor's movement. This effectively prevents the T-shaped plate 1 from detaching from the cable when it swings under force. Thus, the device achieves the advantage of omnidirectional positioning with the conductor, ensuring stable connection, while not affecting the device's position adjustment along the conductor. This solves the problem in existing technologies where the bottom of the grounding trolley needs to be connected to the ground, and the bottom is easily affected by wind, causing it to swing. This leads to the grounding trolley potentially detaching and becoming unstable due to the lack of protective structure on the front side when swinging.
[0023] Please see Figure 1 and Figure 4 The top of the T-shaped plate 1 is provided with a strip groove 9, and the bottom edge of the positioning block 8 is inserted into the inside of the strip groove 9.
[0024] In this utility model, the I-beam 6 is pulled upwards, and then the positioning block 8 is rotated to the vertical direction so that its bottom is aligned and inserted downwards into the interior of the strip slot 9, thereby supporting and positioning the I-beam 6. The operation and adjustment are very convenient and the limiting effect is good.
[0025] Please see Figure 2 and Figure 3 In this configuration, a first spring 61 is fitted on each of the two vertical sections of the I-beam 6. The bottom end of the first spring 61 is fixedly connected to the outer side of the vertical section of the I-beam 6, and the top end of the first spring 61 is fixedly connected to the bottom of the horizontal section of the T-shaped plate 1.
[0026] In this utility model, the first spring 61 maintains a downward pushing force on the I-beam 6, so that the I-beam 6 maintains a downward force on the positioning block 8, making its contact with the strip groove 9 more stable.
[0027] Please see Figure 1 and Figure 2The clamping component 4 includes a threaded rod 41, a sliding frame 42, and a second spring 43. The top end of the threaded rod 41 extends through to the top of the horizontal block 3 and is slidably connected thereto. The top end of the threaded rod 41 is rotatably connected to the sliding frame 42. One side of the back of the sliding frame 42 is slidably connected to the front of the T-shaped plate 1. The lower roller 5 is rotatably mounted on the sliding frame 42. The second spring 43 is sleeved on the outside of the threaded rod 41. The bottom end of the second spring 43 is fixedly connected to the horizontal block 3, and the top end of the second spring 43 is fixedly connected to the sliding frame 42.
[0028] In this invention, by rotating the threaded rod 41 and moving it vertically along the horizontal block 3, the sliding frame 42 is driven to slide along the front of the T-shaped plate 1, thereby driving the lower roller 5 to rise and position the cable. The adjustment is convenient and flexible.
[0029] Please see Figure 1 and Figure 2 Among them, the bottom end of the threaded rod 41 is fixedly connected to a toggle ring 411.
[0030] In this invention, operating the threaded rod 41 via the actuating ring 411 is more convenient and less strenuous.
[0031] Please see Figure 1 Among them, the front of the horizontal section of the T-shaped plate 1 is rotatably connected to two auxiliary rollers 10, which are located directly above the lower roller 5.
[0032] In this invention, the auxiliary roller 10 corresponds to the lower roller 5 to prevent the lower roller 5 from moving upward and clamping the cable, thus preventing the cable from bending under force and ensuring that the cable between the three points remains straight, making it convenient to move along the conductor.
[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
