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

[0032] like Figure 2 The image shows the end beam on the lifting device after welding is completed.

[0033] like Figure 3 The image shows the initial state of the lifting device's upper end beam (hereinafter referred to as the end beam). The end beam includes two mounting plates and several partitions. The two mounting plates are placed at an interval between each other, and are connected to each other by several partitions within the intervals between the two mounting plates, making them a whole. The partitions are spaced apart between the two mounting plates. Each mounting plate also has a pair of mounting holes, and the pair of mounting holes on the upper and lower mounting plates are placed opposite each other.

[0034] See attached document Figure 1 A welding fixture for the upper end beam of a lifting device includes a base plate 1, which is planar. It is understood that the thickness and strength of the base plate 1 are sufficient to ensure that the upper end beam of the lifting device will not deform after installation and rotation. The base plate 1 is fixedly installed on a positioner (existing technology, the working principle will not be described in detail).

[0035] A pair of positioning round tubes 2 are welded on the base plate 1. Their positions are opposite to a pair of mounting holes on the lower mounting plate, and they can extend into the mounting holes to initially position the end beam. The allowance between the positioning round tubes 2 and the mounting holes is 10mm.

[0036] The base plate 1 is also welded with several support legs 3, which are spaced apart from each other and supported in the blank space at the bottom of the end beam. They do not interfere with other parts of the end beam and can create a gap between the end beam and the base plate 1, which is convenient for welding parts at the bottom of the end beam.

[0037] Each support leg 3 is provided with a telescopic support 4, which can move up and down inside the support leg 3; a plurality of threaded holes are uniformly and vertically arranged on the support 4, and a positioning hole is arranged on the support leg 3, so that a bolt can be screwed into any threaded hole of the support 4 from the positioning hole; in use, the height of the support 4 is adjusted, a suitable threaded hole is selected and aligned with the positioning hole, and then the bolt is screwed into the two holes to complete the installation.

[0038] A rubber pad can be mounted on the top of the support 4 to improve the buffering performance, so as to avoid that the end beam is subjected to a large impact force when being lowered onto the base plate 1 after being transported by a lifting tool.

[0039] A limiting assembly 5 is mounted on each side of the base plate 1, which includes a support pipe 5.1 vertically mounted on the base plate 1, and a support arm 5.2 mounted on each side of the support pipe 5.1; a clamping piece 5.3 is slidingly connected to each support arm 5.2, and is used to clamp the two ends of the end beam.

[0040] A through positioning slot is arranged on the support arm 5.2, and a clamping groove is arranged on the end of the clamping piece 5.3 close to the end beam, so that one end of the side plate of the end beam can be clamped into the slot; a threaded rod is arranged at the tail of the clamping piece 5.3 and can slide in the positioning slot, and the threaded rod extends out of the positioning slot; when the clamping piece 5.3 is slid in the positioning slot and abuts against the end face of the end beam, a nut is screwed on the threaded rod to fix the clamping piece 5.3, thereby completing the limiting installation.

[0041] A clamping bolt is further arranged on the support pipe 5.1, which abuts against the side wall of the end beam to avoid sliding displacement of the end beam when rotating.

[0042] It should be noted that, in the present text, relational terms such as first and second are used merely to distinguish one entity or action from another, without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variant thereof are intended to cover non-exclusive inclusions, so that a process, method, article, or apparatus that comprises a list of elements does not only include those elements, but also includes other elements not expressly listed, or other elements inherent to such process, method, article, or apparatus.
