Description

Technical Field

[0001] This utility model relates to the field of electric hoist installation for maintenance, and in particular to an installation tool for electric hoist maintenance. Background Technology

[0002] A rubber-tired gantry crane (TTL) is a mobile crane that operates in container yards. Using its self-elevating trolley mechanism and auxiliary trolley structure, the TTL can move containers within the yard, transporting them to designated locations. Due to the significant weight of the TTL, coupled with the load of the containers it carries, the tires of the trolley mechanism experience considerable stress. Statistics show that tire wear on the trolley mechanism primarily occurs during trolley travel, steering, and stationary operations.

[0003] Currently, when repairing the main beam of a tire crane, a maintenance electric hoist is often required. However, before using the maintenance electric hoist, it must first be installed on the main beam. Traditionally, the maintenance electric hoist is installed by directly hoisting it. But since the maintenance electric hoist is not a perfectly symmetrical component, its center of gravity is not at its center point. This leads to problems such as tilting and swaying during hoisting, requiring constant adjustments to maintain its level, which is very cumbersome. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an installation tool for repairing electric hoists that facilitates the installation of electric hoists.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: an installation fixture for repairing electric hoists, wherein the electric hoist is installed below the main beam, and its innovation lies in: the installation fixture includes An installation platform is provided, comprising an upper hoisting platform, a lower placement platform, and a vertical frame connecting the upper hoisting platform and the lower placement platform. The upper hoisting platform, the lower placement platform, and the vertical frame work together to form a U-shaped installation platform, with the upper hoisting platform located above the main beam and the lower placement platform located below the maintenance electric hoist. The upper hoisting platform is also equipped with a hoisting lug on each side. The maintenance electric hoist is placed on the lower platform and fixed with straps. The lower platform is also equipped with fixing plates for fixing the maintenance electric hoist. The fixing plates are also provided with several through holes for the straps to pass through.

[0006] Furthermore, a wooden tray for supporting the electric hoist for maintenance is placed on the upper surface of the lower placement platform.

[0007] Furthermore, an adjusting lug is provided in the middle of the upright frame. There are two adjusting lugs, which are respectively located on both sides of the upright frame. An adjusting steel wire rope is also connected inside the adjusting lug.

[0008] Furthermore, a first reinforcing plate is provided between the upright frame and the upper hoisting platform, and a second reinforcing plate is provided between the upright frame and the lower placement platform. A through hole for the binding strap to pass through is also provided on the second reinforcing plate.

[0009] The advantages of this utility model are as follows: The installation fixture of this utility model fixes the electric hoist for maintenance through the cooperation of the upper hoisting platform, the lower placement platform and the upright frame. With the help of the installation platform, it is easier to find the center of gravity position so as to achieve stable lifting of the electric hoist for maintenance, which is very convenient.

[0010] The wooden pallet is designed to provide auxiliary support between the electric hoist and the lower platform, preventing relative friction between the electric hoist and the lower platform that could damage it.

[0011] The adjustable lifting lugs on the upright frame are designed to be used in conjunction with the adjustable wire rope to actively lift the upright frame when the electric hoist is being lifted up or down, thereby changing the center of gravity of the entire installation platform so that the electric hoist can be lifted up and down more smoothly.

[0012] Figure 1 This is a schematic diagram of the installation fixture for repairing electric hoists according to this utility model.

[0013] Figure 2 This is a schematic diagram illustrating the coordination between the installation fixture and the maintenance electric hoist of this utility model. Detailed Implementation

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] like Figure 1 , Figure 2 The diagram shows an installation fixture for repairing an electric hoist. The electric hoist 5 is installed below the main beam 4. The installation fixture includes... An installation platform is provided, comprising an upper hoisting platform 1, a lower placement platform 2, and a vertical frame 3 connecting the upper hoisting platform 1 and the lower placement platform 2. The upper hoisting platform 1, the lower placement platform 2, and the vertical frame 3 work together to form a U-shaped installation platform. The upper hoisting platform 1 is located above the main beam 4, and the lower placement platform 2 is located below the maintenance electric hoist 5.

[0016] Two adjustable lifting lugs 33 are installed in the middle of the upright frame 3, one on each side of the upright frame 3. An adjusting wire rope 34 is connected inside each adjusting lug 33. The design of the adjusting lugs 33 on the upright frame 3 is to actively lift the upright frame 3 by cooperating with the adjusting wire rope 34 when lifting the maintenance electric hoist 5, thereby changing the center of gravity of the entire installation platform so that the maintenance electric hoist 5 can be lifted and lowered more smoothly.

[0017] On both sides of the upper hoisting platform 1, there is a hoisting lug 11 for hoisting. The maintenance electric hoist 5 is placed on the lower placement platform 2 and fixed by the binding strap 22. On both sides of the lower placement platform 2, there are fixing plates 21 for fixing the maintenance electric hoist 5. The fixing plates 21 also have several through holes for the binding strap 22 to pass through.

[0018] A wooden tray 23 for supporting the maintenance electric hoist 5 is placed on the upper surface of the lower platform 3. The design of the wooden tray 23 is to provide auxiliary support between the maintenance electric hoist 5 and the lower platform 2, so as to avoid relative friction between the maintenance electric hoist 5 and the lower platform 2, which could lead to damage to the maintenance electric hoist 5.

[0019] A first reinforcing plate 31 is provided between the upright frame 3 and the upper hoisting platform 1, and a second reinforcing plate 32 is provided between the upright frame 3 and the lower placement platform 2. The second reinforcing plate 32 also has a through hole for the binding strap 22 to pass through. The design of the first reinforcing plate 31 and the second reinforcing plate 32 is to provide structural reinforcement for the connection between the upright frame 3 and the upper hoisting platform 1 and the lower placement platform 2, thereby improving the structural strength of the entire installation platform. The second reinforcing plate 32 also has a through hole for the binding strap 22 to pass through, so that it can cooperate with the fixing plate 21. In this way, only one side of the lower placement platform 2 needs to be equipped with the fixing plate 21, and the other side can directly use the second reinforcing plate 32, reducing the number of fixing plates 21.

[0020] When using the installation fixture of this utility model to install the electric hoist 5, first, place the electric hoist 5 on the wooden pallet 23 and secure it with the binding straps 22. A tensioner can be used to tighten the binding straps 22. Adjust the center of gravity of the electric hoist 5, and then begin lifting. Lift the electric hoist 5 100mm off the ground and hold it for 1 minute to ensure there is no shaking, tilting, or other abnormalities. Continue lifting after this. If tilting occurs, adjust it using the adjusting lugs 33 and the adjusting wire rope 34. Lift the entire installation platform to the desired position. Figure 2 As shown in the diagram, proceed with the installation of electric hoist 5. After installation, loosen the straps and lower the fixture.
