Description

Technical Field

[0001] The utility model relates to the field of cross arm installation, in particular to an electric cross arm installation device. Background Art

[0002] The cross arm is an important component of the tower. Its function is to install insulators and hardware to support the conductors and lightning conductors and keep them at a certain safety distance as required.

[0003] Traditional power crossarms still have certain shortcomings during installation: when current workers install crossarms on utility poles, they usually wear foot buckles and safety belts, then climb to the top of the pole with a rope tied to their bodies, and then pull up the rope tied with the crossarm and other components, place the crossarm at a suitable height on the pole, and during installation, ensure that the height of both ends of the crossarm is consistent and there is no large tilt. During this process, workers usually use the naked eye to determine the installation height and inclination angle of the crossarm, which can easily lead to insufficient installation accuracy of the structure. Secondly, it is inconvenient for workers to transport components such as crossarms and clamps up during operation. Moreover, due to the high top of the pole, some components or equipment carried by the workers can easily fall down during construction, causing damage.

[0004] Therefore, it is necessary to provide a new power cross-arm installation device to solve the above technical problems. Utility Model Content

[0005] The technical problem solved by the utility model is to provide an electric crossarm installation device which can improve installation accuracy, facilitate transportation of structural components, and provide good buffering for objects falling from heights.

[0006] In order to solve the above technical problems, the utility model provides an electric cross-arm installation device comprising: a conveying assembly and a positioning assembly, the positioning assembly being arranged on a utility pole, the positioning assembly comprising a limiting member, the top of the utility pole being located on the inner side of the limiting member, the left and right outer walls of the limiting member being threadedly connected with locking bolts, a side wall surface of the limiting member being fixedly connected with a limiting sleeve, a movable member being slidably connected inside the limiting sleeve, a fixing member being fixedly connected with the surface of the movable member located on the lower side of the limiting sleeve, a horizontal plate being arranged at the lower side of the fixing member, spring rods being hinged at the left and right edge positions of the bottom of the fixing member, and two of the spring rods being hinged at the two side edge positions of the top of the horizontal plate respectively;

[0007] The conveying assembly includes a mounting part, which is fixedly connected to a side wall surface of the limiting part away from the limiting sleeve. The mounting part is rotatably connected to a pulley relative to the side wall surface of the limiting part, and a winding rod is fixedly connected to a position on one side of the pulley.

[0008] As a further solution of the present invention, a suspension rope is provided on the surface of the pulley, the bottom of the suspension rope is fixedly connected to a conveying box, and the top of the conveying box is an open structure.

[0009] Through the above technical solution, a conveyor box is specially set up in the device to store various parts and tools required by workers to install crossarms, so that workers do not have to carry heavy objects when climbing to the top of the utility pole. When the conveyor box needs to be transported to the appropriate height, the lifting rope is pulled and lifted through the pulley, and then the lifting rope is tied to the winding rod to fix the position of the conveyor box. In this way, it is very convenient and easy for workers to take tools or parts.

[0010] As a further solution of the present invention, a spirit level is fixedly connected to the surface of the horizontal plate, and supporting feet are fixedly connected to the left and right edges of the bottom of the horizontal plate, and the bottom of the supporting feet is flush with the bottom of the movable part.

[0011] Through the above technical solution, when the positioning assembly is in use, the limiter is first covered on the top of the utility pole, and then the locking bolts on both sides are rotated to fix the limiter on it, and then the movable part is slid so that the bottom of the movable part is in a suitable position on the utility pole and fixed with a fastening bolt. During the process, the worker can determine the installation position by the position of the pointer on the scale, and then install the crossarm through the clamp and make the top and side positions of the crossarm abut against the two legs. Since a spirit level is set on the cross plate, when one end of the crossarm is tilted, the end of the cross plate will compress the spring rod and change the information on the spirit level, allowing the worker to make quick adjustments. This structural design makes the crossarm have higher accuracy when installed.

[0012] As a further solution of the present invention, a buffer assembly is provided on the outside of the utility pole, and the buffer assembly includes a shell. Two shells are provided and are respectively located on the left and right sides of the utility pole. A buffer pad is fixedly connected to the inside of the shell, and a fastening bolt is threadedly connected to the side wall surface of the limit sleeve.

[0013] Through the above technical solution, when workers are working on the top of a utility pole, they can place the two shells on both sides of the utility pole. In this way, when equipment or components fall from above, the buffer pads below can act as a buffer. After the structure is used, the two shells are docked and the pins are inserted into the corresponding ear plates. The structure can then be transported by casters, and the positioning components and other structures can be placed inside the tool box, making it convenient for workers to move the installation device.

[0014] As a further solution of the present invention, the two relatively distant side wall surfaces of the shells are fixedly connected with ear plates, the two ear plates are connected by a pin, and the side wall surface of the shell on one side is fixedly connected with a tool box, and the tool box surface is hinged with a top cover.

[0015] Through the above technical solution, the two shells are docked and the pins are inserted into the corresponding ear plates. Then, the positioning components and other structures are placed in the tool box to facilitate workers to move the entire installation device through casters.

[0016] As a further solution of the present invention, armrests are fixedly connected to the two relatively distant side wall surfaces of the shells, and casters are installed on the edge positions of both sides of the shell surface close to the armrest.

[0017] Through the above technical solution, the cooperation of the handrails and casters can facilitate workers to move the installation device, and the structural design is humanized.

[0018] As a further solution of the present invention, a scale is fixedly connected to the surface of the movable part, and a pointer is fixedly connected to the side wall surface of the limit sleeve. The end of the pointer is located on one side of the scale and is flush with the top of the pole.

[0019] By adopting the above technical solution, the pointer is flush with the top of the electric pole. Thus, when adjusting the position of the movable part, the installation height of the cross arm can be determined by observing the length between the bottom of the movable part and the pointer.

[0020] Compared with the related art, the power cross-arm installation device provided by the utility model has the following beneficial effects:

[0021] 1. In the present invention, when the positioning assembly is in use, the limiting part is first covered on the top of the electric pole, and then the locking bolts on both sides are rotated to fix the limiting part on it. Then the movable part is slid so that the bottom of the movable part is in a suitable position on the electric pole and fixed with the fastening bolts. During the process, the worker can determine the installation position by the position of the pointer on the scale. Then the cross arm is installed through the clamp and the top two sides of the cross arm are abutted against the two legs. Since a spirit level is provided on the cross plate, when one end of the cross arm is tilted, the end of the cross plate will compress the spring rod and change the information on the spirit level, so that the worker can make quick adjustments. This structural design makes the installation of the cross arm have a high degree of accuracy.

[0022] 2. In the present invention, a conveying box is specially provided in the device to store various parts and tools required by workers to install crossarms, so that workers do not have to carry heavy objects when climbing to the top of the utility pole. When the conveying box needs to be transported to a suitable height, the lifting rope is pulled and lifted by the pulley, and then the lifting rope is tied to the winding rod to fix the position of the conveying box, so that it is very convenient and easy for workers to take tools or parts. When workers are working on the top of the utility pole, the two shells can be placed on both sides of the utility pole.

[0030] Please combine Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the overall structure of a power cross-arm installation device in the present utility model; Figure 2This is a partial structural diagram of a power cross-arm installation device in the utility model. Figure 1 ; Figure 3 This is a partial structural diagram of a power cross-arm installation device in the utility model. Figure 2 ; Figure 4 This is a partial structural diagram of a power cross-arm installation device in the utility model. Figure 3 A power cross arm installation device includes:

[0031] The conveying component 2 and the positioning component 3 are arranged on the electric pole. The positioning component 3 includes a limit member 12. The top of the electric pole is located on the inner side of the limit member 12. The outer walls of the left and right sides of the limit member 12 are threadedly connected with locking bolts 13. The surface of one side wall of the limit member 12 is fixedly connected to the limit sleeve 21. The inner part of the limit sleeve 21 is slidably connected with a movable member 14. The surface of the movable member 14 located on the lower side of the limit sleeve 21 is fixedly connected to a fixing member 17. A horizontal plate 20 is provided at the lower side of the fixing member 17. The left and right edges of the bottom of the fixing member 17 are hinged with spring rods 18. The two spring rods 18 are hinged at the edge positions on both sides of the top of the horizontal plate 20 respectively.

[0032] The conveying assembly 2 includes a mounting member 24, which is fixedly connected to a side wall surface of the limiting member 12 away from the limiting sleeve 21. The mounting member 24 is rotatably connected to a pulley 23 relative to a side wall surface of the limiting member 12, and a winding rod 25 is fixedly connected to a position on one side of the pulley 23.

[0033] like Figure 1-4 As shown, a suspension rope 10 is provided on the surface of the pulley 23, and the bottom of the suspension rope 10 is fixedly connected to a conveying box 9, and the top of the conveying box 9 is an open structure.

[0034] A conveying box 9 is specially provided in the device to store various parts and tools required by workers to install crossarms, so that workers do not have to carry heavy objects when climbing to the top of the utility pole. When the conveying box 9 needs to be transported to a suitable height, the lifting rope 10 is pulled and lifted through the pulley 23, and then the lifting rope 10 is tied to the winding rod 25 to fix the position of the conveying box 9, so that workers can take tools or parts very conveniently and easily.

[0035] like Figure 1-4 As shown, a spirit level 19 is fixedly connected to the surface of the horizontal plate 20 , and supporting feet are fixedly connected to the left and right edges of the bottom of the horizontal plate 20 , and the bottoms of the supporting feet are flush with the bottom of the movable part 14 .

[0036] When the positioning assembly 3 is in use, the limiting part 12 is first covered on the top of the electric pole, and then the locking bolts 13 on both sides are rotated to fix the limiting part 12 on it, and then the movable part 14 is slid so that the bottom of the movable part 14 is in a suitable position on the electric pole and fixed with the fastening bolts 16. During the process, the worker can determine the installation position by the position of the pointer 22 on the scale 15, and then install the cross arm through the clamp and make the top two sides of the cross arm abut against the two legs. Since a spirit level 19 is provided on the cross plate 20, when one end of the cross arm is tilted, the end of the cross plate 20 will compress the spring rod 18 and change the information on the spirit level 19, so that the worker can make quick adjustments. This structural design makes the cross arm have higher accuracy when installed.

[0037] like Figure 1-4 As shown, a buffer assembly 1 is provided on the outside of the utility pole, and the buffer assembly 1 includes a shell 4. Two shells 4 are provided and are respectively located on the left and right sides of the utility pole. A buffer pad 11 is fixedly connected to the inside of the shell 4, and a fastening bolt 16 is threadedly connected to the side wall surface of the limiting sleeve 21.

[0038] When workers are working on the top of a utility pole, they can place the two shells 4 on both sides of the pole. In this way, when equipment or components fall from above, the buffer pads 11 below can act as a buffer. After the structure is used, the two shells 4 are docked and the pins are inserted into the corresponding ear plates 6. The structure can be transported by casters 5, and the positioning component 3 and other structures can be placed in the tool box 7, making it convenient for workers to move the installation device.

[0039] like Figure 1-4 As shown, the side wall surfaces of the two shells 4 that are relatively far away are fixedly connected with ear plates 6, and the two ear plates 6 are connected by pins. The side wall surface of the shell 4 on one side is fixedly connected with a tool box 7, and the surface of the tool box 7 is hinged with a top cover 8.

[0040] The two shells 4 are docked and the pins are inserted into the corresponding ear plates 6 , and then the positioning assembly 3 and other structures are placed in the tool box 7 to facilitate workers to move the entire installation device through the casters 5 .

[0041] like Figure 1-4 As shown, the side wall surfaces of the two shells 4 that are relatively far away are fixedly connected with handrails, and the edge positions on both sides of the shell 4 surface close to the handrail are installed with casters 5.

[0042] The cooperation of the handrail and the casters 5 can facilitate workers to move the installation device, and the structural design is humanized.

[0043] like Figure 1-4As shown, a scale 15 is fixedly connected to the surface of the movable part 14, and a pointer 22 is fixedly connected to the side wall surface of the limiting sleeve 21. The end of the pointer 22 is located on one side of the scale 15 and is flush with the top of the pole.

[0044] Make the pointer 22 flush with the top of the pole. When adjusting the position of the movable member 14, the installation height of the cross arm can be determined by observing the length between the bottom of the movable member 14 and the pointer 22.

[0045] The working principle of the power cross arm installation device provided by the utility model is as follows:

[0046] Step 1: When using the positioning assembly 3, first cover the top of the electric pole with the limiting part 12, then rotate the locking bolts 13 on both sides to fix the limiting part 12 on it, then slide the movable part 14, let the bottom of the movable part 14 be in the appropriate position on the electric pole and fix it with the fastening bolts 16. During the process, the worker can determine the installation position by the position of the pointer 22 on the scale 15, and then install the cross arm through the clamp and make the top and bottom sides of the cross arm abut against the two legs. Since the level 19 is provided on the cross plate 20, when one end of the cross arm is tilted, the end of the cross plate 20 will compress the spring rod 18 and change the information on the level 19, so that the worker can make quick adjustments. This structural design makes the cross arm installation have higher accuracy;

[0047] The second step: A conveying box 9 is specially provided in the device to store various parts and tools required by workers to install crossarms, so that workers do not have to carry heavy objects when climbing to the top of the utility pole. When the conveying box 9 needs to be transported to a suitable height, pull the lifting rope 10 and lift it through the pulley 23. Then, the lifting rope 10 is bolted to the winding rod 25 to fix the position of the conveying box 9, so that it is very convenient and easy for workers to take tools or parts. When workers are working on the top of the utility pole, the two shells 4 can be placed on both sides of the utility pole. In this way, when equipment or parts fall from it, the buffer pad 11 below can act as a buffer. After the structure is used, the two shells 4 are docked and the pins are inserted into the corresponding ear plates 6. The structure can be transported by casters 5, and the positioning component 3 and other structures can be placed inside the tool box 7, which is convenient for workers to move the installation device.
