[0002] Tower crane (hereinafter referred to as tower crane) is one of the indispensable lifting equipment in the modern construction process. It can lift a large amount of building materials, base materials, etc. to a height of tens of meters, and plays an important role in large-scale construction. The bottom support frame of the crane is composed of multiple groups of standard sections, which are spliced and installed to form a crane bracket as high as tens of meters.

[0003] The standard section of a tower crane is composed of two monolithic pieces and several connecting rods. The monolithic piece is welded from two main chords and several connecting pipes. After the standard section monolithic piece is completed, it is necessary to continue to install connectors, steps and other parts on the standard section monolithic piece by welding. Due to the large amount of welding, the deformation caused by welding cannot be completely eliminated after the welding is completed, which will cause the size of the main chord to shift. In severe cases, it will cause the center deviation of the holes during the assembly of the standard section, making assembly difficult and even impossible to install normally. In addition, the step is an important component for the tower crane to achieve self-lifting, and there is no room for error. Therefore, how to reduce the deformation of the standard section monolithic piece after welding and improve the consistency of the standard section is a problem that needs to be solved in this field.

[0020] 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.

[0021] Specific embodiment 1: Please refer to Figure 1-2 A tower crane standard section single chip processing tooling includes: a base 1 and a clamping assembly 2, a positioning assembly 3, a longitudinal pin shaft 4 and a limit assembly 5 arranged on the base 1, wherein the positioning assembly 3 is used to perform preliminary positioning of the standard section single piece placed on the base 1 to improve processing efficiency, the longitudinal pin shaft 4 and the limit assembly 5 are used to limit the standard section single piece horizontally and vertically to improve processing accuracy, and the clamping assembly 2 is used to clamp the standard section single piece and reduce the deformation of the standard section single piece after welding, thereby ensuring the quality of the standard section single piece.

[0022] The existing standard section single piece 6 is composed of two main chords 61 and several connecting pipes. Each main chord 61 is welded with several connecting parts for assembly. In order to meet the standards of tower cranes, each main chord 61 is welded with multiple steps 62. The main function of this processing tooling is to reduce the deformation of the main chord after welding, improve the production quality of the standard section, and improve the consistency of the standard section.

[0023] Specifically, the base 1 is a frame structure formed by a left beam 11, a right beam 12 and a plurality of connecting rods 13; in order to cooperate with the protruding connecting parts of the standard section single piece, the standard section single piece needs to be raised, so in this embodiment, the base 1 includes a plurality of pads 14, and the plurality of pads 14 are placed on the left beam 11 and the right beam 12; further, the left beam 11 and the right beam 12 are both square hollow structures.

[0024] The clamping assemblies 2 are provided in a plurality, and are arranged on the pad 14 in a one-to-two arrangement. This means that each pad 14 is provided with two clamping assemblies 2. During processing, the main chord of the standard section is provided on the pad 14, and the clamping assemblies 2 are distributed on both sides of the main chord to compress the main chord. In this embodiment, the clamping assembly 2 includes a pressure plate, a screw, and a nut. The screw is fixed to the pad 14. The pressure plate and nut are both provided on the screw, with the nut located above the pressure plate. By rotating the nut, the nut can press the pressure plate downward, causing the pressure plate to compress the main chord.

[0025] In one embodiment, a plurality of pressing assemblies 2 are evenly distributed along the length direction of the base 1 so that the pressing force on the standard section piece is balanced and the deformation of the main chord after welding is minimized.

[0026] In one embodiment, the clamping assembly 2 may also be composed of an electrically driven clamping cylinder and a pressure plate arranged at the output end of the clamping cylinder. The clamping cylinder is arranged on the base 1, and the pressure plate is fixedly connected to the output end of the clamping cylinder and is located on the upper side of the base 1. The electrically driven lower pressure plate can move up and down relative to the base 1 to realize the function of clamping or releasing. The electrically driven clamping can save manpower and further improve the clamping efficiency.

[0027] Furthermore, the base 1 also includes a fixing block 15 provided at the front end of the right beam 12, and the fixing block 15 is used to cooperate with the positioning assembly 3 and the longitudinal pin 4; specifically, the positioning assembly 3 includes a positioning plate 31, a front side plate 32 and a rear side plate 33, the positioning plate 31 is provided on the fixing block 15, the front side plate 32 cooperates with the positioning plate 31 and is provided on the inner side of the right beam 12, and the rear side plate 33 is provided at the rear inner side of the right beam 12, and the positioning plate 31, the front side plate 32 and the rear side plate 33 form a right angle. Limiting space, when the standard section single piece is placed on the base 1, the front end of the main chord of the standard section single piece on the right is in contact with the positioning plate 31, and the left side is in contact with the front side plate 32 and the rear side plate 33 at the same time, so as to realize the preliminary positioning of the standard section single piece, which can improve the processing efficiency of the standard section single piece; the longitudinal pin shaft 4 is movably arranged on the fixed block 15, and after the preliminary positioning of the standard section single piece, the longitudinal pin shaft 4 longitudinally penetrates the main chord of the standard section single piece on the right to avoid lateral vibration or displacement of the standard section single piece.

[0028] There are two limit assemblies 5, and the two limit assemblies 5 are respectively placed on the front and rear sides of the upper end of the left beam 11; the limit assemblies 5 include a bracket 51 and a transverse pin 52, and the bracket 51 is fixed to the upper end of the left beam 11. After the initial positioning of the standard section single piece, the transverse pin 52 passes through the bracket 51 through the connecting piece at the lower end of the main chord on the left of the standard section single piece to avoid longitudinal vibration of the standard section single piece and further improve the processing accuracy of the standard section single piece.

[0029] In one embodiment, through holes 16 are provided on the left beam 11 and the right beam 12 for fitting with bolts to install and fix the base 1 .

[0030] Through this technical solution, by arranging a clamping assembly, a positioning assembly, a longitudinal pin shaft and a limit assembly on the base, the standard section single piece can be quickly positioned and stably clamped, which not only improves the processing efficiency of the standard section single piece, but also reduces the deformation of the standard section single piece after welding, and ultimately ensures the quality of the standard section.
