They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art will understand the specific meanings of the above terms based on specific circumstances.

[0029] like Figure 1 - Figure 5 As shown, a lifting maintenance device of the present invention includes a movable bottom 1, a placement platform 2 and a lifting component 4;

[0030] Among them, the top surface of the placement platform 2 is provided with a support assembly;

[0031] The lifting assembly 4 is provided between the movable bottom 1 and the placement platform 2 and is used to adjust the distance between the placement platform 2 and the bottom surface;

[0032] After the placement platform 2 is lifted by the lifting assembly 4 , the supporting assembly contacts the maintenance component 5 and acts on both sides of the bottom of the maintenance component 5 .

[0033] Two parallel support bars 30 are provided on the placement platform 2 at a certain distance. During maintenance, the electric hoist trolley is driven above the device, and the placement platform 2 is lifted by the lifting assembly 4. When the placement platform 2 reaches the arc surface of the electric hoist trolley drum cover, the driving assembly 50 is stuck on the support assembly and prevents it from rolling. The lifting assembly 4 continues to lift it. When the left and right suspension wheels of the driving assembly 50 are off the track, the driving assembly 50 that needs maintenance can be removed.

[0034] After the repair is completed, reinstall it as it was, lower the lifting assembly 4, and the repair is completed.

[0035] Compared with the large lifts used in traditional maintenance, this device is simple to operate and low in cost. The maintenance device can be placed at a fixed point and does not occupy extra ground space. During maintenance, there is no need to specifically remove ground objects, which reduces the preparation time for maintenance.

[0036] Furthermore, traditional maintenance methods require both hands to pull the electric hoist and hoist the entire trolley to the ground for repair. This manual hoist method requires long preparation time, multiple parts to be removed, and time-consuming, requiring two or more people to complete the repair, making it unsafe. This device reduces preparation time, requires fewer parts to be removed, and takes less time, allowing one person to complete the repair safely.

[0037] Specifically, the support assembly includes support bars 30 that are symmetrically arranged on the upper end of the placement platform 2 and extend along the length direction.

[0038] In order to reduce the damage caused by the contact between the support bar 30 and the repair workpiece, a chamfered angle, specifically a chamfered angle 300, can be provided on the support bar 30 at the contact position with the repair part 5.

[0039] In addition, the support assembly can also be set into other structural forms, such as Figure 4 、 Figure 5 As shown, a supporting base plate 60 is provided on the placement platform 2, and supporting side plates 61 are symmetrically and inwardly inclined on both sides of the supporting base plate 60. When the lifting assembly 4 lifts the placement platform 2, the supporting side plates 61 meet the requirements of supporting the maintenance workpiece. At the connection between the supporting side plates 61 and the supporting base plate 60 on both sides, several brackets 62 are equidistantly provided along the width direction. Each bracket 62 is rotatably connected to a support wheel 63. In this form of support assembly, when the supporting side plates 61 are in contact with the maintenance workpiece, the support wheels 63 play a role of support and guidance, so that the support force on the maintenance workpiece is more uniform, avoiding any abnormalities.

[0040] A placement groove 20 is provided on the upper surface of the placement platform 2 , and tools such as maintenance wrenches can be placed on the placement groove 20 . The opening of the placement groove 20 facilitates the storage of various tools.

[0041] In addition, the mobile base 1 has a plurality of roller assemblies 10 , and the roller assemblies 10 are provided with foot brakes 100 .

[0042] It is worth noting that the outer layer of the roller in the roller assembly 10 can be coated with a material having a buffering effect, such as rubber material, which can reduce damage to the ground and improve mechanical stability.

[0043] The rollers in the roller assembly 10 are universal wheels, which can facilitate the movement of the entire device and reduce transportation costs.

[0044] The push-pull handle 11 is arranged at the tail of the movable base 1 or an unrestricted place. By operating the push-pull handle 11, force is applied to the entire device to move it to the place to be repaired, which is more convenient to use.

[0045] This device is a special tool for repairing electric hoist trolleys. It uses the lifting component 4 to force the placement platform 2 to rise together with the part to be repaired 5, so that the repair part 5 is off the track, making it convenient to remove the upper traveling component 50. Among them, the lifting component 4 can adopt a guide rail type, a crank arm type, a scissors type, a chain type, a loading and unloading platform and other structural methods. The present embodiment adopts a scissors type structure, and its driving source is a cylinder. A jack can also be used as a driving source. The above-mentioned lifting component, cylinder or jack and connection are existing technologies and do not fall within the scope of protection of this application. Therefore, they at least have the beneficial effects brought by the technical solution of the above-mentioned embodiment and will not be repeated here.

[0046] The fixed connection not specifically mentioned above may be a connection method such as riveting, welding, bolt connection, etc., and the movable connection may be a connection method such as hinged connection.

[0047] The above are only embodiments of the present invention. Common knowledge such as the known specific structures and characteristics in the scheme is not described in detail here. Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date. Ordinary technicians in the relevant field can improve and implement this scheme based on their own abilities under the guidance of this application. Some typical known structures or methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the utility model, they can also make several variations and improvements, which should also be regarded as the scope of protection of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
