Description

Technical Field

[0001] The utility model relates to the technical field of steel bar welding, in particular to a steel bar welding mesh bearing frame. Background Art

[0002] Steel bar welded mesh is a mesh in which longitudinal steel bars and transverse steel bars are arranged at a certain interval and at right angles to each other, and all intersections are welded together, such as cold-rolled ribbed steel bar welded mesh, prefabricated beam positioning mesh, etc. In the process of welding steel bar mesh, Jierong bearing frame is usually used as the welding platform of steel bar mesh, as shown in the steel bar welded mesh bearing frame disclosed in China Patent Network (public announcement number CN219966927U). When such a device is used, it is composed of a supporting component and a fixing component. First, the steel bar is placed on the first fixed block on the welding frame, and then the fixing component drives the threaded rod to rotate through the motor so that the threaded block drives the connecting frame to move, and the extrusion plate and spring on the first fixed block are squeezed by the extrusion rod on the second fixed block to fix the steel bar, so as to improve the stability of the steel bar mesh during welding.

[0003] However, there are still some shortcomings in the above-mentioned public patents and the steel welded mesh support frame adopted in the existing market: the existing method of using two sets of fixed blocks to press and fix the steel mesh, and then performing stable welding, although it can perform relatively stable pressure positioning work on the steel mesh, it can only be adapted to the welding work of a single type of steel mesh, and the flexible use performance is relatively single, and the use limitations are relatively large. To this end, those skilled in the art provide a steel welded mesh support frame to solve the problems raised in the above background technology. Utility Model Content

[0004] The main purpose of the utility model is to provide a steel bar welded mesh bearing frame, which can effectively solve the problem that the existing steel bar welded mesh bearing frames in the background technology have relatively single flexibility of use.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a steel bar welded mesh bearing frame, comprising two sets of lifting brake components facing each other and two sets of bearing frame components horizontally oppositely installed between the two sets of lifting brake components, and the two sets of bearing frame components are symmetrically arranged at an angle of 90 degrees;

[0006] The lifting brake assembly comprises a designated base and a supporting top seat, and a lifting electric push rod is installed between the designated base and the supporting top seat;

[0007] The support frame assembly includes a support frame which is installed in a relative form on a designated base and a supporting top seat in sequence. Both sides of the frame of the support frame are rotatably connected with alignment screws, and the outer side of the shaft rod of each group of alignment screws is symmetrically sleeved with an alignment slide guided by the support frame. A alignment guide rod is installed between two adjacent groups of alignment slides. The outer side of the arm rod of the alignment guide rod is slidably connected with multiple groups of alignment sleeves, and a steel bar sleeve is provided at the upper end of the shaft sleeve of the alignment sleeve.

[0008] As a further solution of the utility model: a braking mechanism for driving the positioning screw is arranged on one side of the frame of the supporting frame, and the braking mechanism includes an adjusting motor installed on the supporting frame along the axis direction of the positioning screw, and a pulley A is arranged at the output end of the adjusting motor, and a pulley B is arranged at one end of the axis of the positioning screw, and pulley A and pulley B are connected by a transmission belt, and traction pulleys for tensioning the transmission belt are symmetrically arranged on both sides of the body of the adjusting motor.

[0009] As a further solution of the utility model: the alignment screw rod is bounded by a center line, and positive and negative thread teeth that are compatible with the alignment slide are symmetrically arranged on both sides of the center line.

[0010] As a further solution of the utility model: a tightening knob which is pressed against the positioning guide rod is screwed on one side of the shaft sleeve of the positioning sleeve.

[0011] As a further solution of the utility model: the steel bar clamping sleeve is a U-shaped sleeve structure.

[0012] As a further solution of the utility model: the upper end of the support of the designated base is provided with a plurality of guide sleeves arranged circumferentially along the lifting electric push rod, and the lower end of the support of the supporting top seat is provided with a plurality of lifting guide rods guided by the guide sleeves arranged circumferentially along the lifting electric push rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When welding the steel mesh, the utility model first pre-adjusts the spacing and orientation of the steel sleeves in the two sets of support frame assemblies based on the size of the steel mesh to maintain a suitable lateral spacing to adapt to the welding of the transverse and longitudinal steel bars of the steel mesh. It has flexible regulation and adaptation performance and can adapt to the welding of steel meshes of different sizes.

[0015] 2. When welding the steel bar welding mesh, the utility model uses the lifting brake assembly as a power source to push the upper bearing frame assembly downward and overlap with the lower bearing frame assembly, so that the steel bar sleeves remain in a staggered overlapping state, and then the transverse steel bars are inserted into the bottom steel bar sleeves in turn. After the insertion is completed, the longitudinal steel bars are inserted into the upper steel bar sleeves in turn and placed vertically on the transverse steel bars. Then, the lifting brake assembly is continuously moved downward to brake, which drives the upper steel bar sleeves to be pressed downward, generates downward pressure, presses the longitudinal steel bars and the transverse steel bars downward into position, and performs stable welding work.

The traction pulleys 26 for tensioning the transmission belt 27 are symmetrically provided on both sides of the body of the adjusting motor 24. By controlling the operation of the adjusting motor 24, the pulley A25 is driven to rotate, and the transfer transmission of the transmission belt 27 is utilized to drive the pulley B28 to rotate, and then the positioning screw rod 22 is driven to rotate. As a power source, the horizontally relative steel bar sleeves 212 are pushed to slide symmetrically, and the spacing between them is adjusted and calibrated in a wide range to adapt to the load-bearing welding work of steel meshes of different lengths.
