Description

Technical Field

[0001] This utility model relates to the field of equipment maintenance technology, and in particular to a mobile maintenance platform. Background Technology

[0002] In current new energy power plants, such as photovoltaic power stations and wind farms, ladders are commonly used maintenance tools. Their principle is based on simple mechanical support, allowing maintenance personnel to reach the equipment for repair. During operation, maintenance personnel must manually move the ladder to a suitable position, adjust the angle, and ensure its stability before climbing to perform maintenance work.

[0003] In existing technologies, the safety belts on maintenance platforms are generally fixed in one position. To allow workers to move freely, the length of the safety belts is increased. However, in the event of a fall, a longer safety belt will cause the worker to swing in the air, increasing the safety risk. At the same time, a longer safety belt may also be caught by the machine, causing other safety risks.

[0004] Therefore, a maintenance platform that can move freely with staff and has a relatively short safety belt is needed. Utility Model Content

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0028] In current new energy power plants, such as photovoltaic power stations and wind farms, ladders are commonly used maintenance tools. Their principle is based on simple mechanical support, allowing maintenance personnel to reach the equipment for repair. During operation, maintenance personnel must manually move the ladder to a suitable position, adjust the angle, and ensure its stability before climbing to perform maintenance work.

[0029] In existing technologies, the safety belts on maintenance platforms are generally fixed in one position. To allow workers to move freely, the length of the safety belts is increased. However, in the event of a fall, a longer safety belt will cause the worker to swing in the air, increasing the safety risk. At the same time, a longer safety belt may also be caught by the machine, causing other safety risks.

[0030] To resolve the above technical issues, please refer to Figure 1This application provides a mobile maintenance platform 3, which may include a mobile trolley 1, a lifting rod 2 and a maintenance platform 3, with the lifting rod 2 located between the mobile trolley 1 and the maintenance platform 3.

[0031] Among them, the mobile trolley 1 serves as the base of the mobile maintenance platform 3. The mobile trolley 1 can move on the construction ground. Specifically, the mobile trolley 1 has multiple wheels. The driving force of the mobile trolley 1 can be pushed by the operator, driven by an electric motor, or driven by an internal combustion engine.

[0032] The lifting boom 2 is used to adjust the height of the maintenance platform 3. Specifically, the lifting boom 2 can be a scissor lift, mast lift, boom lift, sleeve cylinder lift, or truss lift.

[0033] The maintenance platform 3 may include a base plate and a circumferential frame. The base plate is set on the mobile trolley 1, and the circumferential frame is set on the base plate, together with the base plate defining the working space for the operator. The circumferential frame may include a front frame, a rear frame, a left frame, and a right frame. The front frame, left frame, rear frame, and right frame are connected in sequence to form the circumferential frame. A door that can be opened and closed is formed on the front frame or the rear frame. A ladder is provided on one side of the mobile trolley 1. The ladder is on the same side as the door. The operator climbs up the maintenance platform 3 by climbing the ladder, opens the door, and enters the inside of the circumferential frame to carry out the work.

[0034] Please see Figures 2 to 5 The right frame may include a railing 4, a horizontal slide bar 6, a connecting slider 8, a vertical frame 7, a vertical slide bar 9, and an interface base 10.

[0035] The railing 4 includes a front vertical bar, a horizontal bar, and a rear vertical bar connected in sequence. The horizontal bar extends horizontally, while the front and rear vertical bars extend vertically, forming an inverted U-shape.

[0036] The horizontal slide bar 6 is located below the crossbar. One end of the horizontal slide bar 6 is rotatably connected to the front vertical bar, and the other end is rotatably connected to the rear vertical bar. The horizontal slide bar 6 can rotate around the central axis of the horizontal slide bar 6.

[0037] The connecting slider 8 is sleeved on the outer circumferential side of the horizontal slide rod 6 and can slide along the extension direction of the horizontal slide rod 6. The cross-section of the horizontal slide rod 6 is rectangular, which can prevent the connecting slider 8 from rotating relative to the horizontal slide rod 6 and ensure the stability of the connecting slider 8 sliding along the horizontal slide rod 6.

[0038] The vertical frame 7 extends vertically and is located on the side surface of the connecting slider 8 away from the circumferential frame. The upper and lower ends of the vertical frame 7 extend outward toward the circumferential frame to form flanges.

[0039] The vertical slide bar 9 is connected between the flanges at the upper and lower ends of the vertical frame 7.

[0040] The interface base 10 is sleeved on the circumferential outer side of the vertical slide rod 9. The interface base 10 can slide along the extension direction of the vertical slide rod 9. The interface base 10 is provided with a safety belt interface, which is used to connect the operator's safety belt to ensure the safety of the operator during the construction process.

[0041] In this way, by setting up the horizontal slide bar 6, the connecting slider 8, the vertical frame 7 and the vertical slide bar 9, the interface base 10 can move back and forth and up and down, and can rotate around the axis of the horizontal slide bar 6. This allows the safety belt to move smoothly in multiple directions with the operator, adapting to various operating positions of the operator, ensuring the operator's freedom of movement and improving construction efficiency.

[0042] It is understandable that the left frame can have the same structure as the right frame, that is, the left frame can include structures such as railing 4, horizontal slide bar 6, connecting slider 8, vertical frame 7, vertical slide bar 9, and interface base 10.

[0043] In some embodiments of this application, please refer to Figure 2 and Figure 5 The mobile maintenance platform 3 may also include a connecting frame 5. One side of the connecting frame 5 is fixedly connected to the rear vertical rod, and the other side is provided with a connecting hole. The end of the horizontal slide rod 6 facing the connecting frame 5 is a rotating shaft 18. The rotating shaft 18 passes through the connecting hole and can rotate relative to the connecting hole.

[0044] Therefore, by setting the connecting frame 5, a rotatable connection between the horizontal slide bar 6 and the rear vertical bar is achieved.

[0045] It is understandable that the horizontal slide bar 6 and the front vertical bar can also be rotatably connected through the connecting bracket 5.

[0046] In order to ensure the stability of the fixed connection between the connecting frame 5 and the rear vertical rod, a diagonal bracing structure is set at the connection position between the rear vertical rod and the connecting frame 5 to improve the structural strength.

[0047] Furthermore, the connecting frame 5 is also provided with a connecting cavity, the connecting hole communicates with the connecting cavity, the rotating shaft 18 extends into the connecting cavity, and a balance plate 19 is provided at one end of the rotating shaft 18 that extends into the connecting cavity. At least part of the balance plate 19 projected onto the plane where the connecting hole is located is located outside the connecting hole.

[0048] Therefore, by setting the balance plate 19, the rotational connection between the horizontal slide rod 6 and the connecting frame 5 can be realized, while the rotating shaft 18 can be prevented from falling out of the connecting hole, thus ensuring the stability of the rotational connection between the horizontal slide rod 6 and the connecting frame 5.

[0049] In some embodiments of this application, a first support spring 20 and a second support spring are provided in the connecting cavity. The first support spring 20 is located on the upper side of the balance plate 19, with one end of the first support spring 20 abutting against the inner wall of the connecting cavity and the other end abutting against the balance plate 19. The second support spring is located on the lower side of the balance plate 19, with one end of the second support spring abutting against the inner wall of the connecting cavity and the other end abutting against the balance plate 19.

[0050] In this way, by setting the first support spring 20 and the second support spring, the horizontal slide bar 6 always has the force to return to its initial state. When the operator falls, the presence of the first support spring 20 and the second support spring can provide cushioning for the operator and protect the operator's waist.

[0051] The number of first support springs 20 is multiple. In specific implementation, the number of first support springs 20 can be two, and the two first support springs 20 are symmetrically arranged about the axis of the horizontal slide bar 6.

[0052] Furthermore, there can be multiple second support springs. In specific implementation, there can be two second support springs, which are symmetrically arranged about the axis of the horizontal slide bar 6.

[0053] Furthermore, the first support spring 20 and the second support spring are symmetrically arranged about the balance plate 19, which can be two first support springs 20 and two second support springs symmetrically arranged about the balance plate 19.

[0054] It is understandable that the first support spring 20 and the second support spring have the same specifications.

[0055] Therefore, it can be ensured that the first support spring 20 and the second support spring apply symmetrical forces to the balance plate 19, so that the horizontal slide bar 6 always has the tendency to return to its initial state.

[0056] In some embodiments of this application, please refer to Figure 3 and Figure 4 The interface base 10 is provided with an L-shaped mounting groove 11. One end of the mounting groove 11 passes through the side wall of the interface base 10 facing the outer side of the circumferential frame to form a first side opening, and the other end passes through the front or rear side wall of the interface base 10 to form a second side opening.

[0057] The interface base 10 also includes an L-shaped push block 12, a locking block 17 and a connecting rod 13. The push block 12 is located in the mounting groove 11. The push block 12 includes a first end and a second end. The first end extends out of the first side opening and the second end extends out of the second side opening.

[0058] Both the locking block 17 and the connecting rod 13 are located on the side of the interface base 10 away from the circumferential frame. The locking block 17 is located on the interface base 10 and has a locking hole. The connecting rod 13 is located between the first end and the locking hole. The connecting rod 13 is connected to the first end. The outer diameter of the connecting rod 13 is smaller than the inner diameter of the locking hole. The width of the first side opening is greater than the width of the first end. The push block 12 can move in the extension direction of the connecting rod 13, so that the connecting rod 13 can extend into or pull out of the locking hole.

[0059] In this way, when the operator fastens the seat belt, pressing the push block 12 switches the connecting rod 13 from the state of being inserted into the lock hole to the state of being pulled out of the lock hole. Then, the installation strap is put onto the connecting rod 13, and the connecting rod 13 is switched from the state of being pulled out of the lock hole to the state of being inserted into the lock hole, thereby realizing the fastening of the seat belt.

[0060] It should be noted that the width of the first side opening is sufficient to allow the push block 12 to move between the positions of being inserted into the locking hole and being pulled out of the locking hole.

[0061] Furthermore, the mounting groove 11 includes a reset sidewall opposite to the second side opening, and a reset spring 16 is provided in the mounting groove 11. The reset spring 16 is always clamped between the reset sidewall and the push block 12.

[0062] Therefore, when the operator fastens the seat belt, pressing the push block 12 switches the connecting rod 13 from the state of being inserted into the lock hole to the state of being pulled out of the lock hole. Then, the installation strap is put onto the connecting rod 13, and the connecting rod 13 is released. Under the action of the return spring 16, the connecting rod 13 switches from the state of being pulled out of the lock hole to the state of being inserted into the lock hole, thereby realizing the fastening of the seat belt.

[0063] In some embodiments of this application, the mobile maintenance platform 3 may further include a transfer frame 14, which is detachably disposed on the interface base 10 and covers the connecting rod 13 and the first end.

[0064] Specifically, the adapter frame 14 has an adapter groove 15, which covers the push block 12 and connecting rod 13 protruding from the interface base 10, reducing dust from entering and affecting the elasticity of the reset spring 16.
