Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to a power engineering maintenance rack. Background Technology

[0002] Maintenance racks are essential auxiliary equipment used in power engineering maintenance. They are crucial for the installation, inspection, and maintenance of power facilities, primarily used for high-altitude operations, equipment support, and cable laying. For example, a maintenance rack for power engineering (publication number CN216072965U) includes casters above the ground. A stable base plate is fixedly installed on the upper surface of each caster. T-shaped uprights are fixedly installed on both sides of the upper surface of the stable base plate. A sliding personnel carrier is located in the center of the inner side of each T-shaped upright. Elastic limiting devices are fixedly installed on both sides of the upper surface of the personnel carrier. This maintenance rack for power engineering utilizes a compression spring to drive a moving rod and a second compression block to compress a first compression block, causing a push rod and a limiting block to insert into the T-shaped upright for better limiting and fixing of the personnel carrier. This effectively improves the safety and stability of the personnel carrier during use, reduces the probability of accidents, and facilitates safer use. However, this maintenance rack used in power engineering still has the following drawbacks in actual use:

[0003] Some maintenance racks use electric lifting, but the complex maintenance environment can easily damage the electrical equipment, leading to rack malfunctions and affecting their use. Traditional maintenance racks without electric drive structures are mostly fixed in height, making it inconvenient to quickly adjust the height according to different maintenance needs. To address these issues, there is an urgent need for innovative designs based on existing maintenance racks. Utility Model Content

[0004] The purpose of this utility model is to provide a power engineering maintenance rack to solve the problem mentioned in the background art that some maintenance racks use electric drive lifting, but the complex maintenance environment can easily damage the power equipment, which in turn causes the maintenance rack to malfunction and affect its use. Traditional maintenance racks without electric drive structure are mostly fixed in height, which is inconvenient to quickly adjust the height of the maintenance rack according to different maintenance heights.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a power engineering maintenance frame, including a support frame, with movable wheels installed at the bottom of the support frame, and a base plate fixed to the inner side of the support frame, and the base plate being hollowed out;

[0006] It also includes: a climbing frame, symmetrically fixed on both sides of the support frame, the climbing frame having a "U" shaped structure, a protective frame fixed at the edge of the base plate, and the highest point of the protective frame being higher than the highest point of the support frame;

[0007] An extension assembly is disposed on the inner side of the top of the support frame. The extension assembly is used for maintenance at higher locations and can be stored on the support frame.

[0008] Preferably, the extension assembly includes a movable plate disposed on the inner side of the top of the support frame, and the movable plate and the support frame form a rotating structure, and the rotation range of the movable plate is 0-90°, and the movable plate adjusts the working height of the maintenance rack by rotating.

[0009] Preferably, the movable plate is hollow, and a connecting plate passes through the end of the movable plate away from the support frame. The connecting plate and the movable plate are slidably connected, and the movable plate can slide inside the movable plate when the connecting plate is pulled.

[0010] Preferably, the connecting plate has a "C" shaped cross-section, and the length of the upper end of the connecting plate is greater than the length of its lower end. Furthermore, a through groove is provided at the edge of the connecting plate, so that when the connecting plate moves, its upper end can first contact the upper end of the support plate.

[0011] Preferably, the movable plate and the connecting plate are symmetrically distributed about the vertical axis of the base plate, and the end of the movable plate near the support frame is in close contact with the inner side of the support plate. The support plate has a "C" shaped cross-section. The contact between the support plate and the movable plate can limit its movement and prevent it from rotating.

[0012] Preferably, the support plate and the support frame are in a sliding connection, and a spring is provided between the inner side of the support plate and the support frame, so that the support plate can automatically return to its original position after being resisted by the elasticity of the spring.

[0013] Preferably, a support block is fixed to the inner side of the protective frame, and the surface of the support block is in close contact with the lower edge of the connecting plate, so that the support block can provide support for the connecting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this power engineering maintenance frame can reduce the failure rate of the maintenance frame during use, and the height of the maintenance frame can be quickly adjusted according to different maintenance needs, thereby meeting different maintenance requirements. The specific details are as follows:

[0015] 1. When maintenance is required at a lower level, push the connecting plate to slide inside the movable plate. After moving a certain distance, the upper end of the connecting plate can contact the support plate, and push the support plate to slide on the support frame. In this way, the support plate releases its support on the movable plate, and the movable plate and connecting plate can be rotated downwards by 90° to fit against the support frame, which makes it convenient to perform maintenance while standing on the base plate.

[0016] Furthermore, when the movable plate is in a vertically downward position, it can also abut against the support plate to prevent it from moving in the opposite direction;

[0017] 2. Rotate the movable plate upwards and pull the connecting plate to move. Stop pushing the support plate. The spring's rebound will cause it to move in the opposite direction and support the edge of the movable plate to ensure stability in a horizontal state. After the connecting plate moves, it can also re-contact the support block to ensure stability when stepping on the connecting plate. The maintenance frame will not easily collapse.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figures 1-6 The present invention provides the following technical solution:

[0027] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a power engineering maintenance frame, comprising a support frame 1, with casters 2 installed at the bottom of the support frame 1, and a base plate 3 fixed to the inner side of the support frame 1, the base plate 3 being hollow; further comprising: a climbing frame 4, symmetrically fixed to both sides of the support frame 1, the climbing frame 4 having a "U" shaped structure, a protective frame 5 fixed to the edge of the base plate 3, the highest point of the protective frame 5 being higher than the highest point of the support frame 1; an extension component, disposed on the inner side of the top of the support frame 1, the extension component being used for maintenance at higher locations, and the extension component being able to be stored on the support frame 1; the maintenance frame can be moved to a designated position by the casters 2 during use, the casters 2 having a self-locking structure to ensure the stability of the maintenance frame, and then climbed to a higher location by the climbing frame 4, or maintenance can be performed on a lower location on the base plate 3.

[0028] Example 2: Some maintenance racks use electrically driven lifting mechanisms. However, complex maintenance environments can easily damage electrical equipment, leading to rack malfunctions and affecting usability. Traditional maintenance racks without electrically driven mechanisms typically have a fixed height, making it inconvenient to quickly adjust the rack height according to different maintenance needs. Therefore, this example uses the following technical solution: Figure 1 and Figures 3-5 The extension assembly includes a movable plate 6 disposed on the inner side of the top of the support frame 1, and the movable plate 6 and the support frame 1 form a rotating structure, with the movable plate 6 having a rotation range of 0-90°; the movable plate 6 is hollow, and a connecting plate 7 passes through the end of the movable plate 6 away from the support frame 1, and the connecting plate 7 and the movable plate 6 are slidably connected; the connecting plate 7 has a "C" shaped cross-section, and the length of the upper end of the connecting plate 7 is greater than the length of its lower end, and a through groove 8 is provided at the edge of the connecting plate 7; both the movable plate 6 and the connecting plate 7 are symmetrically distributed about the vertical axis of the base plate 3, and the end of the movable plate 6 near the support frame 1 is in close contact with the inner side of the support plate 9, and the support plate 9 has a "C" shaped cross-section. Structure: When maintenance personnel are performing maintenance at heights, they can stand on the movable plate 6 and connecting plate 7. The protective frame 5 provides protection and enhances safety. When maintenance is required at lower levels, the connecting plate 7 is first pushed to slide inside the movable plate 6. After moving a certain distance, the upper end of the connecting plate 7 can contact the support plate 9, and the support plate 9 is pushed to slide on the support frame 1. In this way, the support plate 9 releases its support from the movable plate 6, and the connecting plate 7 also moves away from the support block 51. The movable plate 6 and connecting plate 7 can then be rotated downwards by 90° to fit against the support frame 1. This makes it convenient to stand on the base plate 3 for maintenance. When the movable plate 6 is in a vertically downward position, it can also resist the support plate 9 to prevent it from moving in the opposite direction.

[0029] Example 3: Existing maintenance racks have poor stability when the pedal is pressed, and are prone to shaking and denting. Therefore, this example uses the following technical solution, such as... Figure 4 and Figure 6 The support plate 9 and the support frame 1 are in close sliding connection, and a spring is provided between the inner side of the support plate 9 and the support frame 1; the inner side of the protective frame 5 is fixed with a support block 51, and the surface of the support block 51 is in close contact with the lower edge of the connecting plate 7; the movable plate 6 is rotated upward and the connecting plate 7 is moved through the through groove 8, and the support plate 9 is no longer pushed. The spring rebound can drive it to move in the opposite direction and support it at the edge of the movable plate 6 to ensure stability in a horizontal state. After the connecting plate 7 moves, it can also re-contact with the support block 51. The support block 51 ensures stability when stepping on the connecting plate 7, and the maintenance frame will not easily collapse.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
