Description

Technical Field

[0001] This utility model relates to the field of substation maintenance technology, and in particular to a mobile substation primary equipment installation tool vehicle based on a design platform. Background Technology

[0002] Substation maintenance is crucial for ensuring the stable operation and safety of the power system. Different types and sizes of tools are used depending on the maintenance target. Therefore, a tool cart is needed to store all the tools for easy use.

[0003] Therefore, a mobile substation primary equipment installation tool cart based on a design platform, with publication number CN217182738U, is described in the prior art. The device is pushed to a designated work location, and then two bidirectional lead screws are rotated to cause two adjacent sliders to slide and approach each other inside a groove. Under the action of clamping blocks, the device can be fitted onto the outside of the utility pole. The electric reciprocating screw rotates to drive slider B to reciprocate within groove B. As slider B moves, it drives one end of the support rod to move. After the support rod moves, its left side can press against the outer wall of the utility pole. Furthermore, as slider B moves, the support rod rotates, pressing against the outer wall of the utility pole, thus pushing the device upwards. When slider B moves to the right, because the device's center of gravity is located on the right side of the utility pole, the two sets of clamping blocks ensure the device remains stable on the utility pole. Also, when slider B moves to the right, the left side of the support rod can rise under the action of spring A.

[0004] However, when the device rises, the clamping block provides lateral clamping force, while the strut provides longitudinal thrust. Therefore, in order not to affect the rise of the device, it is necessary to reduce the lateral clamping force of the clamping block on the utility pole. However, during the rise of the device, the utility pole is always in contact with the clamping block (although the lateral clamping force is reduced). Under the action of contact friction, the surface of the clamping block or the utility pole is easily worn. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a mobile substation primary equipment installation tool vehicle based on a design platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mobile substation primary equipment installation tool cart based on a design platform, comprising a tool cart, a horizontally arranged retaining ring detachably installed on one side of the tool cart, a collar for fitting onto a utility pole rotatably installed on the inner wall of the retaining ring, an end cap for fastening to the top of the utility pole above the collar, several winches distributed around the perimeter of the end cap, a bevel gear fixedly installed at one end of the winch winding shaft extending outward through the winch housing, a bevel gear ring rotatably connected to the outer side of the end cap and meshing with several bevel gears, a winch rope extending downward for connecting to the collar, threaded rings threaded to both ends of the collar, several rollers for rolling connection with the surface of the utility pole installed on the inner wall of the threaded ring, and a hollowed-out design for connecting the winch rope at the outer end of the threaded ring away from the collar.

[0007] Preferably, the collar is divided into two symmetrical semi-circular segments, and the outer side of the collar is rotatably connected to several rollers that are rotatably connected to the bottom end of the retaining ring.

[0008] Preferably, the winch housing is fixedly mounted with a mounting bracket, and the top edge of the end cap is hollowed out and the end cap is connected to the mounting bracket by bolts.

[0009] Preferably, a mating ring is provided between the end cap and the collar, and a motor push rod that is detachably connected to the mating ring is installed below each of the winches, and the winch rope passes through the telescopic end of the motor push rod located downwind.

[0010] Preferably, the top of the mating ring is also hollowed out, one end of the electric push rod cylinder is L-shaped with a certain arc and overlaps the surface of the mating ring, the hollow part of the electric push rod cylinder is also connected by bolts, and the mating ring is divided into two equal semi-circular sections.

[0011] Preferably, both the threaded ring and the retaining ring are divided into two equal symmetrical semi-circular segments.

[0012] Preferably, the tool cart has several vertically arranged tool boards distributed along the length of the tool cart.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, a retaining ring is set to install the collar on the surface of the utility pole. By setting an end cap installed at the top of the utility pole, the collar is pulled up on the surface of the utility pole by the winch rope set around the end cap. This simultaneously drives the retaining ring and the tool cart to rise along the surface of the utility pole, thus ensuring that the collar can rise and fall stably and smoothly without contacting the surface of the utility pole, and ensuring that the inside of the collar will not be damaged by friction.

[0015] 2. In this utility model, each winch on the end cover is provided with an electric push rod installed on the mating ring directly below it. Therefore, the rope released from the winch passes through the telescopic end of the electric push rod directly below. Thus, the position of the rope from the surface of the utility pole can be controlled by the telescopic extension of the electric push rod, ensuring that the released rope does not slide against the surface of the utility pole and preventing the rope surface from being worn due to the friction of the utility pole.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-4As shown, a mobile substation primary equipment installation tool cart based on a design platform includes a tool cart 1. A horizontally arranged retaining ring 10 is detachably installed on one side of the tool cart 1. A collar 2 for fitting onto a utility pole is rotatably installed on the inner wall of the retaining ring 10. An end cap 3 for fastening to the top of the utility pole is provided above the collar 2. Several winches 6 are distributed around the sides of the end cap 3. One end of the winch 6's winding shaft passes through the outer shell of the winch 6 and extends outward, with a bevel gear 8 fixedly installed. A bevel tooth ring 9 that meshes with the bevel gear 8 is rotatably connected to the outer side of the end cap 3. The winch rope of the winch 6 extends downward to connect to the collar 2. Both ends of the collar 2 are threadedly connected to threaded rings 12. Several rollers 11 for rolling contact with the surface of the utility pole are installed on the inner wall of the threaded ring 12. The outer side of the threaded ring 12 away from the collar 2 is hollowed out for connecting the winch rope. In use, the collar 2 is fitted onto the pole. On the utility pole, personnel use tools to climb the pole and attach the end cap 3 to the top of the pole. By using the meshing connection between the bevel ring 9 and the bevel gear 8, when one of the winches 6 rotates to release the rope, the bevel gear 8 at the end of its internal winding shaft rotates synchronously. Therefore, the bevel gears 8 in other positions will rotate simultaneously under the meshing connection of the bevel ring 9, so that the ropes of all the winches 6 on the end cap 3 can be released at the same time. By connecting the released ropes to the collar 2, the winches 6 can wind up the ropes and pull the collar 2 to drive the tool cart 1 to rise along the surface of the utility pole. That is, the tool cart 1 is only pulled upward by the ropes, which ensures the stability of the tool cart 1 in raising and lowering. Furthermore, by using the rollers 11 inside the collar 2 to contact the surface of the utility pole, it is ensured that the inner wall of the collar 2 does not contact the surface of the utility pole. Therefore, when the collar 2 is raised and lowered, the corresponding rollers 11 will roll on the surface of the utility pole.

[0024] In addition, this solution only requires a commercially available servo motor to drive the rotation of one of the winch 6 spools, and the other winch 6 spools can be rotated synchronously under the cooperation of the bevel gear 8 and the bevel gear ring 9.

[0025] This solution presents the challenge of installing the device on an already erected utility pole. Therefore, the collar 2 is divided into two symmetrical semi-circular sections. Several rollers 14, rotatably connected to the bottom of the retaining ring 10, are rotatably connected to the outer edge of the collar 2. Both the threaded ring 12 and the retaining ring 10 are divided into two symmetrical semi-circular sections. Figure 4 It is known that the collar 2 and the retaining ring 10 can be hinged and rotated to open, making it convenient for the collar 2 and the retaining ring 10 to enter and exit the surface of the utility pole by prying them open. When the collar 2 rises, several rollers 14 on its surface will drive the retaining ring 10 and the tool cart 1 to rise synchronously. And by using the rotation of the rollers 14, after the collar 2 rises to a fixed height, the personnel can adjust the position of the tool cart 1 by turning the tool cart 1 so that the retaining ring 10 can be rotated under the support of several rollers 14.

[0026] In this design, the placement of the winch 6 is susceptible to interference from the cable support frame on the utility pole. Therefore, the following measures are taken: a mounting bracket 7 is fixedly installed on the outer shell of the winch 6; the top edge of the end cap 3 is hollowed out and the hollowed-out end cap 3 is connected to the mounting bracket 7 by bolts; by using bolts to connect the mounting bracket 7 to the hollowed-out parts at different positions on the end cap 3, the installation position of the winch 6 can be adjusted to ensure that the released rope from the winch 6 is not interfered with by the lines or equipment erected on the surface of the utility pole; a mating ring 4 is provided between the end cap 3 and the collar 2, and is coaxially distributed with the collar 2; an electric push rod 5 is installed below each winch 6 and is detachably connected to the mating ring 4; the winch rope of the winch 6 passes through the telescopic end of the electric push rod 5 located downwind; the top of the mating ring 4 is also hollowed out; one end of the cylinder of the electric push rod 5 is L-shaped with a certain arc and overlaps the mating ring 4. The mating ring 4 and the cylinder body of the electric push rod 5 are connected by bolts to the hollowed-out parts of the mating ring 4. The mating ring 4 is divided into two symmetrical semi-circular sections. The mating ring 4 is also hinged and can be opened, which facilitates the installation of the mating ring 4 on the utility pole. The bolts pass through the hollowed-out parts at different positions on the end face of the cylinder body of the electric push rod 5 and the mating ring 4, which facilitates the adjustment of the installation position of the electric push rod 5. That is, each winch 6 on the end cover 3 is provided with an electric push rod 5 installed on the mating ring 4 directly below it. Therefore, the rope released from the winch 6 passes through the telescopic end of the electric push rod 5 directly below it. Thus, the position of the rope from the surface of the utility pole can be controlled by the extension and retraction of the electric push rod 5, ensuring that the released rope does not slide against the surface of the utility pole and preventing the rope surface from being worn due to the friction of the utility pole.

[0027] To facilitate tool selection: Several tool boards 13 are vertically arranged and distributed along the length of the tool cart 1. The tool boards 13 are installed in the tool cart 1 in a parallel manner. Therefore, when selecting a tool, the tool board 13 storing the tool will not touch other tool boards 13 when it is pulled out.

[0028] The working principle is as follows: The end cap 3 is attached to the top of the utility pole, and the installation position of the mounting bracket 7 is adjusted according to the location of the lines and devices erected on the pole, ensuring that there are no obstructions below the winch 6. A mating ring 4 is installed on the utility pole below the end cap 3, and an electric push rod 5 is installed directly below each winch 6 on the mating ring 4. The released rope from the winch 6 passes through the telescopic end of the electric push rod 5 directly below. The collar 2 is installed on the utility pole, and the retaining ring 10 is installed on the outside of the collar 2. The tool cart 1 is connected to the retaining ring 10 using bolts. One end of several released ropes is connected to the top of the collar 2. The rotation of several winches 6 winds up the rope, pulling the collar 2 up along the surface of the utility pole. When the collar 2 rises, several rollers 14 on its surface drive the retaining ring 10 and the tool cart 1 to rise synchronously. Using the rotation of the rollers 14, after the collar 2 rises to a fixed height, personnel can adjust the position of the tool cart 1 by moving the tool cart 1, which is supported by the rollers 14 and rotates the retaining ring 10.

[0029] The wiring diagrams of the electric actuator 5 and winch 6 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the electric actuator 5 and winch 6 will not be explained in detail.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
