Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a steel reinforcement skeleton welding equipment for the production of concrete cover plates. Background Technology

[0002] Concrete cover plates are sturdy cover plates made of concrete, possessing characteristics such as high strength, waterproofing, fire resistance, and corrosion resistance. They are commonly used to cover and protect underground facilities such as manhole covers and access hatches, and can also be used as covering materials for building roofs and floors. Due to their excellent performance and wide range of applications, concrete cover plates play an important role in construction, road, water conservancy, and other engineering projects. During the production of concrete cover plates, a steel reinforcement skeleton needs to be placed before pouring and compacting concrete. The steel reinforcement skeleton needs to be tied or welded into shape for use. Traditionally, the tying is mostly done manually, which is inefficient. To improve this situation, a steel reinforcement skeleton welding equipment for concrete cover plate production is proposed.

[0003] As disclosed in CN216758711U, a welding device for precast steel reinforcement cages includes a robotic arm, a welding torch, and a base. One end of the robotic arm is fixed to the base, and the other end is connected to the welding torch. The welding operation is completed by adjusting the welding torch posture through the robotic arm. The base includes a connecting device and a fixing device. One end of the robotic arm is set on the connecting device, and the connecting device is movably fixed to the ground through the fixing device. The fixing device includes a hydraulic cylinder and a fixing plate. The connecting device includes a connecting plate, a connecting hole, and rollers.

[0004] Although it enables movement on the ground via the connecting plate, it also uses the hydraulic cylinder and the fixed plate to fix the connecting plate on the ground, thereby fixing the robot arm. The lifting and lowering of the hydraulic cylinder facilitates the fixing operation of the robot arm, and the connecting plate can also be used to transfer and move the robot arm without frequently tightening each bolt fixing the robot arm, making the operation convenient and quick.

[0005] However, this does not solve the problem that existing welding equipment is not conducive to convenient linkage, centering, clamping and fixing of reinforcing bars, and circumferential rotation for welding reinforcing bars, and is not conducive to comprehensive welding of the contact surface of the reinforcing bars, thus affecting the convenience of welding. Utility Model Content

[0006] The purpose of this utility model is to provide a steel reinforcement cage welding device for the production of concrete cover plates, so as to solve the problem mentioned in the background art that the welding device is not convenient for the linkage centering and clamping of steel reinforcement and the circumferential rotation welding of steel reinforcement, which is not conducive to the comprehensive welding of the contact surface of steel reinforcement and affects the convenience of welding.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a steel reinforcement cage welding device for concrete cover plate production, comprising a welding table and a placement block. The placement block is installed at the top of the welding table, and a transverse screw mechanism is installed at the top of the welding table on one side of the placement block. A left sleeve is movably installed inside the placement block. A movable ring is installed at the output end of the transverse screw mechanism. A right sleeve is provided inside the movable ring and is movably connected to the movable ring. A bearing frame is installed at the end of the left and right sleeves that are close to each other. A drive motor is installed at the bottom of the welding table, and a pulley assembly is installed at the output end of the drive motor, extending to the surface of the left sleeve. An electric push rod is movably installed inside the welding table on one side of the transverse screw mechanism.

[0008] Preferably, the output end of the electric push rod is equipped with a push arm, and a linkage arm is movably installed at the top end of the push arm.

[0009] Preferably, a support block is installed on the top of the welding table on one side of the push arm, and a pin is installed on the side wall of the linkage arm, and the linkage arm is movably connected to the support block through the pin.

[0010] Preferably, a welding torch is provided at the end of the linkage arm away from the push arm, and the welding torch is fixedly connected to the linkage arm.

[0011] Preferably, the support frame has three sets of integrated frames with equal spacing inside, and the integrated frames are fixedly connected to the support frame.

[0012] Preferably, threaded rods are movably mounted on the side walls of the integrated frame, and servo motors are mounted on the outer walls of the integrated frame, with the output end of the servo motor connected to the threaded rods.

[0013] Preferably, the surface of the threaded rod is fitted with a threaded sleeve, and the threaded sleeve is threadedly connected to the threaded rod.

[0014] Preferably, an adjusting arm is movably mounted on the side wall of each threaded sleeve, and a clamping arm is movably mounted on the end of each adjusting arm away from the threaded sleeve, and the clamping arm is movably connected to the integrated frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the welding equipment not only realizes convenient linkage centering clamping and fixing of steel bars and circumferential rotation welding of steel bars, which facilitates comprehensive welding of the contact surface of steel bars, but also improves the convenience of welding.

[0016] (1) When it is necessary to fabricate the steel reinforcement skeleton in the concrete cover plate, the length of a single set of steel reinforcement can be extended by welding and then bent into shape. The two sets of steel reinforcement are inserted into the left sleeve and the right sleeve respectively. Then, the servo motor is turned on, and the servo motor drives the threaded rod to rotate. The threaded rod drives the adjusting arm to rotate through the threaded sleeve. The adjusting arm drives the clamping arm to rotate, so that the three sets of clamping arms contact the steel reinforcement and clamp and fix the steel reinforcement. Then, the transverse screw mechanism is turned on, and the transverse screw mechanism drives the movable ring, the right sleeve and the steel reinforcement in the right sleeve to move, so that the end faces of the two sets of steel reinforcement contact each other. The electric push rod is turned on, and the electric push rod drives the push arm to move. Under the support of the support block, the push arm drives the linkage arm to rotate around the pin shaft. The linkage arm drives the welding gun to rotate and contact the connection position of the steel reinforcement. The welding gun is used to spot weld the contact position to make the two sets of steel reinforcement initially connected. This realizes convenient linkage centering clamping and fixing of steel reinforcement, and facilitates welding of the contact surface of steel reinforcement.

[0017] (2) The drive motor drives the left sleeve to rotate through the pulley assembly, and the left sleeve drives the steel bar to rotate in a circle, thereby completing the welding of the contact surface of the steel bar. After the welding is completed and a long steel bar is formed, it is bent and shaped, and then the subsequent welding is carried out to complete the welding operation of the steel bar skeleton. This realizes convenient circular rotation welding of steel bars and improves the convenience of welding. Attached Figure Description

[0026] When it is necessary to fabricate the steel reinforcement cage inside the concrete cover slab, the length of a single set of steel bars can be extended by welding, and then bent into shape. Two sets of steel bars are inserted into the left sleeve 8 and right sleeve 3 respectively. Then, the servo motor 19 is turned on, driving the threaded rod 20 to rotate.
