Description

Technical Field

[0001] The utility model relates to the technical field of standard section production equipment, in particular to a welding tool for a tower crane standard section diagonal brace. Background Art

[0002] Currently, the diagonal brace of a standard section in a tower crane is welded together by welding the diagonal brace body to connectors at both ends. During welding, the diagonal brace body and the connector are perpendicular to each other, forming a 90-degree angle. The two are fixedly connected at this angle by welding, and a fillet weld is formed at the angle after welding. Based on the structural strength requirements of the standard section of the tower crane, the cross-section of the fillet weld must be an isosceles right triangle structure, that is, the weld leg heights of the weld must be consistent. To achieve this, the diagonal brace must be tilted before welding. In the current diagonal brace welding operation, the diagonal brace is manually placed on an inclined frame and then rotated and welded. After welding one end, it needs to be manually adjusted to interchange the ends of the diagonal brace before rotating and welding again. This welding operation requires a lot of manpower, which not only increases labor intensity and reduces work efficiency, but also makes the welding quality unstable. Utility Model Content

DETAILED DESCRIPTION

[0019] The following describes the specific embodiments of the present invention in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the present invention. Although the present invention is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, not limiting, of the scope of the present invention.

[0020] Specific embodiment 1: Please refer to Figure 1-3 A welding tool for the standard section diagonal brace of a tower crane comprises: a base 1, a supporting mechanism 2, a lifting cylinder 3, and two sets of universal displacement mechanisms 4. The supporting mechanism 2 is fixedly arranged on the base 1 for supporting the diagonal brace body, and the diagonal brace body can rotate circumferentially around the axis on the supporting mechanism 2; the lifting cylinder 3 is arranged on the base 1 and its position corresponds to the supporting mechanism 2, and is used to change the size of the inclination angle between the diagonal brace and the horizontal plane; the two sets of universal displacement mechanisms 4 are symmetrically arranged on both sides of the supporting mechanism 2, and are used to fix the connecting parts of the diagonal brace and make the connecting parts rotate synchronously with the diagonal brace body to realize rotary welding; this welding tool is applied to the standard section diagonal brace of a tower crane, which can not only ensure the welding quality, but also greatly reduce the labor intensity of welding and improve the welding efficiency.

[0021] The support mechanism 2 includes a support seat 21, a support plate 22 and two groups of roller seats 23. The support seat 21 is fixedly arranged on the base 1, and the middle part of the support plate 22 is rotatably connected to the top of the support seat 21. The support seat 21 and the support plate 22 form a structure similar to a seesaw; the output shaft of the jacking cylinder 3 is connected to the lower end of the support plate 22. When the jacking cylinder 3 works, it can reciprocate and drive one end of the support plate 22 to lift up and the other end to fall; the two groups of roller seats 23 are respectively placed at both ends of the support plate 22; the roller seat 23 includes a fixed seat 231 and two rollers 232, and the two rollers 232 are movably arranged on the fixed seat 231. When the diagonal support rod body is placed on the support mechanism 2, the diagonal support rod body is slidably connected to the two rollers 232 at the corresponding positions; the setting of the two groups of roller seats 23 can not only support the diagonal support rod, but also reduce the contact area between the diagonal support rod and the support mechanism 2, and manual rotation of the diagonal support rod will be more labor-saving.

[0022] The universal displacement mechanism 4 includes a support 41, a clamping disk, a rotating shaft 44 and a connecting rod 45. The support 41 is arranged on the base 1, the rotating shaft 44 is movably arranged on the top of the support 41, and the connecting rod 45 is fixedly connected to the middle of the rotating shaft 44; the clamping disk includes a turntable 42 and a fixed clamp 43; the axis of the turntable 42 is rotatably connected to the connecting rod 45, and the fixed clamp 43 is arranged on the turntable 42 and faces the supporting mechanism 2. Through such an arrangement, the fixed clamp 43 and the turntable 42 can rotate around the axis of the connecting rod 45 to achieve synchronous rotation with the diagonal support rod body; through the rotating shaft 44, the fixed clamp 43 and the turntable 42 can also be flipped up and down, so that the diagonal support rod body and the connecting piece are perpendicular to each other to form a 90-degree angle.

[0023] Furthermore, the support 41 is detachably connected to the base 1 by screws; during implementation, a plurality of connection holes 11 are provided on the base 1 and are distributed in an array along the length direction of the base 1. The two supports 41 can be installed close to or far away from each other along the connection holes 11. The variable distance between the two supports 41 can enable the welding tool to adapt to diagonal support rods of different lengths, thereby improving the scope of application of the welding tool.

[0024] The fixing clamp 43 includes a fastening screw 431, an upper clamping plate 432 and a lower clamping plate 433. The upper clamping plate 432 and the lower clamping plate 433 are fixed on the turntable 42. The fastening screw 431 is provided on the upper clamping plate 432. By rotating the fastening screw 431, the fastening screw 431 can move closer to or away from the lower clamping plate 433 to achieve clamping. For center stability, the upper clamping plate 432 and the lower clamping plate 433 are symmetrically distributed around the axis of the turntable 42. During welding, the connecting piece is provided between the upper clamping plate 432 and the lower clamping plate 433, and the connecting piece can be tightened by rotating the fastening screw 431.

[0025] In one embodiment, a slide rail that cooperates with the support 41 can also be set on the base 1. The two supports 41 can be moved closer to or farther away from each other through the slide rail. For diagonal support rods of different lengths, it will be more convenient to adjust the distance between the two universal displacement mechanisms 4.

[0026] Through this technical solution, a support mechanism, a lifting cylinder, and two sets of universal displacement mechanisms are arranged on the base. The support mechanism includes a support plate and two sets of roller seats arranged on the support plate. The diagonal support rod is placed on the roller seat to make the circumferential rotation of the diagonal support rod more labor-saving. The output shaft of the lifting cylinder is connected to the support plate. The two sets of universal displacement mechanisms for fixing the connecting parts are symmetrical and movably arranged on both sides of the support mechanism. Using this welding tool to weld the standard section diagonal support rod of the tower crane can not only ensure the welding quality, but also greatly reduce the labor intensity of welding and improve welding efficiency.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
