Description

Technical Field

[0001] This utility model relates to the field of line maintenance technology, and in particular to a power station protective hanger that facilitates line maintenance. Background Technology

[0002] Power station protective gantry systems, designed to facilitate line maintenance, are typically used to lift and lower suspended platforms. The main function of this system is to provide a safe lifting platform to assist workers in the inspection, maintenance, and installation of power lines at height. In power systems, power station protective gantry systems, through the lifting and lowering of suspended platforms, enable workers to safely reach different locations along power lines to perform necessary operations.

[0003] Existing power plant protective hangers are typically designed with casters installed at the bottom to facilitate easy movement when line maintenance is required. Once the hanger reaches the desired position, the casters lock in place using their self-locking function. However, relying solely on the casters' self-locking function to fix the hanger in place results in relatively weak friction due to the small contact area between the casters and the ground. When the hanger is subjected to external forces (such as wind, collisions, or human pushing or pulling), the casters are prone to misalignment or movement due to insufficient friction, thus affecting the stability and safety of the equipment. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where the hanger is fixed in the required position solely by the self-locking function of the casters. When the hanger is subjected to external forces (such as wind, collisions, or human pushing and pulling), the casters are prone to misalignment or movement due to insufficient friction, thus affecting the stability and safety of the equipment.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a power station protective hanger for convenient line maintenance, comprising a hanger body, with bases fixedly installed on both sides of the bottom of the hanger body, and motors fixedly installed on the rear top sides of both bases, and further comprising:

[0006] Both of the bases have a forward rotation screw movably embedded in their rear interior sides, and the output shafts of both motors are fixedly mounted on the rear side of the forward rotation screw.

[0007] Two reverse lead screws are fixedly installed on the front side of the forward lead screw. The outer surfaces of the front sides of the two reverse lead screws are movably embedded in the inner front side of the base. The outer surfaces of the two forward lead screws and the two reverse lead screws are threaded with first sliders. The top side of the inner wall of the two bases is provided with first sliding grooves. The four first sliders are divided into two groups of two.

[0008] In a preferred embodiment, the tops of both sets of first sliders are slidably connected to the inner surface of the first groove, the bottoms of the four first sliders are fixedly mounted with first hinges, and the interiors of the four first hinges are movably connected with support rods.

[0009] The technical effect of adopting the above-mentioned further solution is that the support rod can be flipped through the first hinge and the second hinge.

[0010] In a preferred embodiment, the other end of each of the four support rods is movably connected to a second hinge, and the four second hinges are divided into two groups of two, with a support plate fixedly installed at the other end of each group of second hinges.

[0011] The technical effect of adopting the above-mentioned further solution is that when the support rod flips, the support plate can be driven to move through the second hinge.

[0012] In a preferred embodiment, both support plates are slidably connected inside the base, and omnidirectional wheels are provided around the bottom of both support plates.

[0013] The technical effect of adopting the above-mentioned further solution is that the support plate can drive the universal wheels to lift and lower.

[0014] In a preferred embodiment, a basket is slidably connected inside the hanger body, and a second sliding groove is provided on both sides of the inner wall of the hanger body.

[0015] The technical effect of adopting the above-mentioned further solution is that it allows the suspended basket to slide inside the suspension frame body.

[0016] In a preferred embodiment, a second slider is fixedly installed on both sides of the suspended basket, and the outer surfaces of the two second sliders are slidably connected to the inner surface of the second slide groove. A winch is provided on both sides of the top of the suspension frame body.

[0017] The technical effect of adopting the above-mentioned further solution is that it allows the second slider to slide through the second groove.

[0018] In a preferred embodiment, both winches are equipped with steel cables inside, and both steel cables are movably embedded inside the frame body. Two positioning wheels are provided on both sides of the frame body, and the four positioning wheels are divided into two groups of two.

[0019] The technical effect of adopting the above-mentioned further solution is that the steel cable can be wound up by a winch.

[0020] In a preferred embodiment, both sets of positioning wheels are movably connected to the outer surface of the steel cables, and the other end of each of the two steel cables is provided with a support member, which is fixedly sleeved on the outer surface of the suspended platform.

[0021] The technical effect of adopting the above-mentioned further solution is that when the steel cable is wound up, the basket can be pulled up inside the frame body by the support members.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] This invention, through the design of the forward-rotating screw and support rod structure, not only facilitates the movement of the hanger body, but also ensures that after the hanger body moves to the desired position, the motor drives the forward and reverse screws to reverse, ensuring that the universal wheels retract into the base. This prevents the hanger body from accidentally moving or tilting. The retraction of the universal wheels allows the bottom of the base to fit tightly against the ground, enhancing the stability and safety of the hanger body during operation and reducing the risk of accidents caused by accidental displacement of the universal wheels. This invention solves the problem in existing technologies where the hanger is fixed in the desired position solely by the self-locking function of the universal wheels. When the hanger is subjected to external forces (such as wind, collisions, or human pushing and pulling), the universal wheels are prone to misalignment or movement due to insufficient friction, thus affecting the stability and safety of the equipment.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1, please refer to Figure 1-5 This utility model provides a technical solution: a power station protective hanger for convenient line maintenance, including a hanger body 1, with bases 101 fixedly installed on both sides of the bottom of the hanger body 1, and motors 103 fixedly installed on the rear top sides of the two bases 101. It also includes: forward-rotating lead screws 102 movably embedded in the rear sides of the interior of the two bases 101, with the front sides of the output shafts of the two motors 103 fixedly installed on the rear sides of the forward-rotating lead screws 102; two reverse-rotating lead screws 104, each fixedly installed on the front side of the forward-rotating lead screws 102, with the front outer surfaces of the two reverse-rotating lead screws 104 movably embedded in the front interior of the bases 101; and first sliders 105 threadedly connected to the outer surfaces of the two forward-rotating lead screws 102 and the two reverse-rotating lead screws 104. The inner walls of both bases 101 are provided with first sliding grooves 106. The four first sliders 105 are divided into two groups of two. The tops of the two groups of first sliders 105 are slidably connected to the inner surface of the first sliding grooves 106. The bottoms of the four first sliders 105 are fixedly installed with first hinges 107. The interiors of the four first hinges 107 are movably connected with support rods 108. The other ends of the four support rods 108 are movably connected with second hinges 109. The four second hinges 109 are divided into two groups of two. The other ends of the two groups of second hinges 109 are fixedly installed with support plates 110. The two support plates 110 are slidably connected to the interior of the bases 101. The bottom of the two support plates 110 is provided with universal wheels 111 around its perimeter.

[0033] In this embodiment, the operator can first start the motor 103 through its power supply system. During operation, the motor 103 transmits power to the forward lead screw 102 via its output shaft, and the forward lead screw 102 transmits power to the reverse lead screw 104. When the forward and reverse lead screws 102 and 104 rotate, they drive the first slider 105 to slide in opposite directions through the first slide groove 106. While the first slider 105 is sliding, the first hinge 107 pushes the support rod 108, causing it to flip via the second hinge 109. When the second hinge 109 flips, it presses down on the support plate 110, allowing the support plate 110 to slide downwards inside the base 101, extending the omnidirectional wheel 111 out of the base 101. Then, the operator can push the hanger body 1, causing the omnidirectional wheel 111 to rotate, thus moving the hanger body 1. Once the hanger body 1 is moved to the desired position, the operator... The operator can use motor 103 to drive the forward screw 102 and the reverse screw 104 to reverse, thereby causing the first slider 105 to move relative to each other. During this movement, the support plate 110 can slide upward inside the base 101 via the support rod 108, which allows the universal wheel 111 to retract into the base 101, ensuring that the bottom of the base 101 is in contact with the ground. The structure of the forward screw 102 and the support rod 108 not only facilitates the movement of the hanger body 1, but also ensures that after the hanger body 1 moves to the desired position, the motor 103 drives the forward screw 102 and the reverse screw 104 to reverse, ensuring that the universal wheel 111 retracts into the base 101, preventing the hanger body 1 from moving or tilting accidentally. The retraction of the universal wheel 111 ensures that the bottom of the base 101 is in close contact with the ground, enhancing the stability and safety of the hanger body 1 during operation and reducing the risk of accidents caused by the accidental displacement of the universal wheel 111.

[0034] Example 2, as Figure 1-5 As shown, a basket 2 is slidably connected inside the hanger body 1. A second sliding groove 201 is provided on both sides of the inner wall of the hanger body 1. A second slider 202 is fixedly installed on both sides of the basket 2. The outer surfaces of the two second sliders 202 are slidably connected to the inner surfaces of the second sliding grooves 201. A winch 205 is provided on both sides of the top of the hanger body 1. A steel cable 204 is installed inside each of the two winches 205. The two steel cables 204 are movably embedded inside the hanger body 1. Two positioning wheels 206 are provided on both sides of the hanger body 1. The four positioning wheels 206 are divided into two groups of two. The two groups of positioning wheels 206 are movably connected to the outer surfaces of the steel cables 204. A support member 203 is provided at the other end of each of the two steel cables 204. The two support members 203 are fixedly sleeved on the outer surface of the basket 2.

[0035] In this embodiment, after the gantry body 1 is moved to a suitable position, personnel can stand on the basket 2 and start the winch 205 through its drive system. During operation, the winch 205 can wind up the steel cable 204, causing it to slide against the outer surface of the positioning wheel 206. When the steel cable 204 is winding up, the support member 203 can pull the basket 2 upward inside the gantry body 1. At the same time, the basket 2 drives the second slider 202 to slide through the second slide groove 201. Through the structure of the steel cable 204 and the second slider 202, when the basket 2 rises again, the second slider 202 can slide on the inner surface of the second slide groove 201 to maintain the balance of the basket 2 and prevent it from shifting or tilting, thereby improving the safety of operation.

[0036] Working principle: In use, the operator can first start the motor 103 through the power supply system. During operation, the motor 103 drives the output shaft to transmit power to the forward lead screw 102, which in turn drives the reverse lead screw 104. As the forward and reverse lead screws 102 and 104 rotate, they cause the first slider 105 to slide in opposite directions through the first slide groove 106. While the first slider 105 is sliding, the first hinge 107 pushes the support rod 108, causing it to flip via the second hinge 109. When the second hinge 109 flips, it presses down on the support plate 110, allowing it to slide downwards inside the base 101. This allows the universal wheels 111 to extend out of the base 101. The operator can then push the hanger body 1, causing the universal wheels 111 to rotate and move the hanger body 1. Once the hanger body 1 reaches the desired position... Personnel can use motor 103 to drive the forward screw 102 and the reverse screw 104 to reverse, thereby causing the first slider 105 to move relative to each other. During this movement, the support plate 110 can slide upward inside the base 101 via the support rod 108, which allows the universal wheel 111 to retract into the base 101, ensuring that the bottom of the base 101 is in contact with the ground. The structure of the forward screw 102 and the support rod 108 not only facilitates the movement of the hanger body 1, but also ensures that after the hanger body 1 moves to the desired position, the motor 103 drives the forward screw 102 and the reverse screw 104 to reverse, ensuring that the universal wheel 111 retracts into the base 101, preventing the hanger body 1 from moving or tilting accidentally. The retraction of the universal wheel 111 ensures that the bottom of the base 101 is in close contact with the ground, enhancing the stability and safety of the hanger body 1 during operation and reducing the risk of accidents caused by the accidental displacement of the universal wheel 111. In use, after the main body 1 of the gantry is moved to a suitable position, personnel can stand on the suspended basket 2 and start the winch 205 through its drive system. During operation, the winch 205 can wind up the steel cable 204, causing it to slide against the outer surface of the positioning wheel 206. When the steel cable 204 is winding up, the support member 203 can pull the suspended basket 2 to slide upward inside the main body 1. At the same time, the suspended basket 2 drives the second slider 202 to slide through the second slide groove 201. Through the structure of the steel cable 204 and the second slider 202, when the suspended basket 2 rises, it can drive the second slider 202 to slide on the inner surface of the second slide groove 201 to maintain the balance of the suspended basket 2 and prevent it from shifting or tilting, thereby improving the safety of operation.

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 present utility model.
