Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, 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, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figures 1-2 As shown, a crane boom welding fixture in one embodiment of the present invention includes a support assembly 1 and an angle adjustment assembly 2. The support assembly 1 includes a pair of support rings 101. The angle adjustment assembly 2 is rotatably connected to the middle of the pair of support rings 101. The crane boom is placed inside the angle adjustment assembly 2. A clamping assembly 3 is installed on the top end face of the angle adjustment assembly 2. The clamping assembly 3 fixes the crane boom inside the angle adjustment assembly 2. During welding, when it is necessary to adjust and rotate the angle of the crane boom, the angle adjustment assembly 2 is rotated by operating the limiting assembly 4, thereby adjusting the angle of the crane boom. The limiting assembly 4 keeps the crane boom stable after the angle is adjusted.

[0030] like Figures 3-4 As shown, a pair of rotating grooves 1011 are provided on each of the two end faces of the support ring 101. The rotating grooves 1011 are provided on the opposite end faces of the pair of support rings 101. Bearings are installed on the inner walls of the pair of rotating grooves 1011. The angle adjustment assembly 2 includes a fixed base 201 and a limiting ring 205. The outer walls of both ends of the fixed base 201 rotate within the pair of rotating grooves 1011 and are respectively connected to a pair of bearings. A rotating ring 2011 is integrally formed on the outer walls of both ends of the fixed base 201. The outer wall of the rotating ring 2011 is welded to the inner ring of the bearing. By installing bearings on the contact surfaces of the fixed base 201 and the support ring 101 at both ends, the friction between the fixed base 201 and the support ring 101 is greatly reduced, allowing the operator to easily rotate the crane arm.

[0031] A fixed cover plate 202 is installed above the fixed base 201. A rotating assembly for connecting the fixed base 201 and the fixed cover plate 202 is fixedly connected to adjacent end faces on one side. A threaded hole 2021 matching the clamping assembly 3 is opened on the top end face of the fixed cover plate 202. The rotating assembly includes a fixed round rod and a rotating rod. The fixed round rod is fixedly connected to the top end face on one side of the fixed base 201. There are three sets of rotating rods. Each of the three sets of rotating rods has a rotating groove. The three sets of rotating rods rotate on the outer surface of the rotating rod. One end face of one pair of rotating rods at both ends is welded to the bottom end face of the fixed cover plate 202, and one end face of the other set of rotating rods is welded to the top end face of the fixed base 201, thereby realizing the rotation of the fixed cover plate 202 on the fixed base 201.

[0032] Multiple sets of first clamping blocks 2012 are installed on the inner wall of the fixed base 201 for supporting the bottom of the lifting arm. Welding clearance grooves are provided on the outer walls of both the fixed base 201 and the fixed cover plate 202. The welding clearance grooves are opened to the maximum extent without affecting the stability of the lifting arm, increasing the weldable working area and preventing the fixed base 201 and the fixed cover plate 202 from affecting the welding work. Rotating handles 203 are integrally formed on the outer walls of both the fixed base 201 and the fixed cover plate 202. Rotating the rotating handles 203 drives the angle adjustment component 2 and the lifting arm to rotate. Locking blocks 204 are installed on the side wall of the fixed base 201 and the fixed cover plate 202 away from the rotating component. Through the cooperation of the locking blocks 204 and the locking mechanism, the fixed base 201 and the fixed cover plate 202 are fixed, so that the angle adjustment component 2 and the lifting arm remain stable during operation.

[0033] like Figures 4-5 As shown, the clamping assembly 3 includes a knob 301. A threaded rod 302 matching the threaded hole 2021 is fixedly connected to the bottom end face of the knob 301. A limiting plate 303 is fixedly connected to the bottom end face of the threaded rod 302. A second clamping block 304 is rotatably connected below the threaded rod 302. A limiting groove 305 matching the limiting plate 303 is opened on the end face of the second clamping block 304. The outer wall of the limiting plate 303 rotates on the inner wall of the limiting groove 305. The clamping assembly 3 has multiple sets of first clamping blocks 201 located in multiple sets. Directly above 2, after placing the lifting arm into the fixed base 201, close and lock the fixed cover 202. Then, rotate the knob 301 to drive the threaded rod 302 to engage and rotate in the threaded hole 2021, causing the knob 301 to drive the threaded rod 302 and the limiting plate 303 to move downward. At this time, the limiting plate 303 rotates in the limiting groove 305 while driving the second clamping block 304 to squeeze the lifting arm. Together with the first clamping block 2012 below the lifting arm, the lifting arm is clamped, so that the lifting arm is stably fixed in the angle adjustment assembly 2.

[0034] like Figures 6-7 As shown, a limiting component 4 matching the limiting ring 205 is installed on one side wall of the support component 1. One end of the limiting component 4 is engaged in the limiting ring 205 for fixation. The limiting component 4 includes a fixing block 401. Slide grooves 4011 are provided on the outer walls of both ends of the fixing block 401. An avoidance hole 1012 is provided on the side wall of one of the support rings 101. The slide groove 4011 is located on one side of the avoidance hole 1012. An operating rod 402 is installed on one side wall of the fixing block 401. A locking post 4021 is integrally formed on one side wall of the operating rod 402 within the fixing block 401. A spring 403 is fixedly connected to the outer wall of the locking post 4021. One end of the spring 403 near the limiting ring 205 is fixedly connected to the outer wall of the locking post 4021, and the other end is fixed to the inner wall of the fixing block 401. The spring 403 is located within the fixing block 401. Several sets of limiting holes 2051 are provided on the outer wall of the limiting ring 205, and one end of the locking post 4021 passes through the clearance hole 1012 and is engaged with the inner wall of the limiting hole 2051. Figure 6 As shown, during welding, the locking pin 4021 engages with the inner wall of the limiting hole 2051, thereby restricting the rotation of the limiting ring 205 and keeping the welding operation stable. When it is necessary to rotate the crane boom, as... Figure 7 As shown, pulling the operating lever 402 outward causes one end of the locking pin 4021 to move away from the inner wall of the limiting hole 2051. Then, the operator slowly rotates the angle adjustment component 2 and the lifting arm. When the rotation reaches the appropriate welding position, the operator stops, releases the operating lever 402, and causes one end of the operating lever 402 to be locked into the limiting hole 2051 under the action of the spring 403, so that the lifting arm can be stabilized after the angle adjustment is completed.

[0035] In use, the lifting arm is placed into the angle adjustment component 2, and then the angle adjustment component 2 is locked by the locking block 204. The clamping component 3 enhances the stability of the lifting arm within the angle adjustment component 2. During welding, when the angle of the lifting arm needs to be adjusted, the angle adjustment component 2 can be rotated to adjust the angle of the lifting arm. Under the action of the limiting component 4, the lifting arm angle is fixed before and after adjustment, which facilitates the welding work of the workers while ensuring the stability of the work.
