[0002] The welding equipment for drilling rig vehicle frame processing is a device for welding drilling rig vehicle frames.

[0003] The inventor discovered during the process of implementing the utility model that:

[0004] The utility model patent application number CN202020419022.2 discloses an integral welding device for a rotary drilling rig frame assembly, comprising a first motor, a second motor, a seat plate, and a welding gun. The upper side of the seat plate is fixedly connected to a plurality of vertical plates, and a first threaded shaft is rotatably connected between the left and right vertical plates. The first threaded shaft is threadedly connected to a movable frame, and the left end of the first threaded shaft is fixedly connected to a second pulley. A rotating frame is provided, and the frame crossbeam can be fixed using a support plate and a pressure plate. During the welding stage, the frame is flipped using the second motor to facilitate double-sided welding of the frame. A movable frame is provided to drive the welding gun to move left and right to achieve welding of left and right welding lines. A pneumatic slider and slide rail are provided to ensure that the welding gun welds the front and rear welding lines of the frame. The utility model has a simple structure, can perform all-round welding of the frame assembly, and can ensure the flatness of the welding lines and the position of the frame crossbeams and longitudinal beams. It has practical value in the field of construction equipment processing technology.

[0005] However, existing drilling rig frame welding equipment is difficult to use. After the frame is fixed, the frame remains suspended except for the two ends. The frame itself is made of metal and is heavy, which can easily cause slippage and dislocation during the welding process. In addition, the frame needs to be fixed manually, which increases the labor workload and is inconvenient to use. Therefore, improvements are needed. Summary of the Invention

[0006] In order to solve the problems existing in the prior art, the utility model provides a welding device for processing a drilling rig frame.

[0007] To this end, the technical solution of the utility model is: a drilling rig frame processing welding equipment, including a base, a cavity is provided on the top of the base, a hydraulic cylinder is fixedly installed at the bottom of the cavity, a support plate is fixedly installed on the top of the hydraulic cylinder, a welding machine is provided above the support plate, the welding machine is fixedly installed on the mobile mechanism, and the mobile mechanism is fixedly installed on the base.

[0008] There are U-shaped plates at both ends above the support plate. A drive shaft is fixedly installed on the relatively distant side of the two U-shaped plates. The other end of the drive shaft is fixedly installed on drive motor 2, drive motor 2 is fixedly installed on a fixed seat, and the fixed seat is fixed on the base. A bidirectional screw rod is provided on the inner side of the U-shaped plate, and the end of the bidirectional screw rod is connected to the rotation of the U-shaped plate. A driving mechanism is provided at one end of the bidirectional screw rod, and both ends of the bidirectional screw rod are connected to a splint through a nut thread.

[0009] Preferably, a support tube is fixedly mounted at the bottom of the cavity, a guide shaft 1 is slidably mounted within the top of the support tube, and the top of the guide shaft 1 is fixedly connected to the support plate. The guide shaft 1 slides within the support tube to guide the lifting and lowering of the support plate, thereby ensuring the stability of the lifting and lowering of the support plate.

[0010] Preferably, a second guide shaft is provided on one side of the bidirectional screw rod, the end of which is fixedly connected to the U-shaped plate, and the second guide shaft slides through the clamping plate. The clamping plate slides on the second guide shaft to guide the movement of the clamping plate, thereby improving the stability of the clamping plate movement.

[0011] Preferably, the movement mechanism includes two symmetrically arranged linear motors (1), fixed to opposite sides of the top of the base. A support column is mounted on the first linear motor, a strip plate is mounted on the support column, a second linear motor is mounted at the bottom of the strip plate, a motorized telescopic rod is mounted at the bottom of the second linear motor, and a welding machine is fixedly mounted at the bottom of the telescopic rod. The operation of the first and second linear motors, and the telescopic rod, drives the welding machine to perform multi-position horizontal movement and lifting operations, facilitating multi-position welding of the vehicle frame.

[0012] Preferably, a slot is formed at the end of the U-shaped plate, and the drive mechanism includes a sprocket 1, which is fixedly mounted on the bidirectional screw and located at one end of the slot. A sprocket 2 is provided on one side of the sprocket 1, and the sprocket 2 is connected to the sprocket 1 via a chain passing through the slot. A drive motor 1 is fixedly mounted on the sprocket 2, and the drive motor 1 is fixed to the U-shaped plate. The operation of the drive motor 1 provides power for the rotation of the bidirectional screw.

[0013] Preferably, a slip ring mechanism is mounted on the drive shaft. The slip ring mechanism includes a rotor and a stator, wherein the stator and rotor are rotatably connected. The stator is fixedly mounted on the drive shaft and connected to the first drive motor via a wire, while the rotor is fixed to a fixed base via a bracket. The slip ring mechanism provides power to the first drive motor and rotates on the U-shaped plate, thereby reducing the probability of winding damage to the first drive motor's wire.

[0014] Beneficial effects: Compared with the prior art, the present invention can raise the support plate freely below the position between the two U-shaped plates, so that the support plate can be raised to support the frame during welding, and can be lowered to leave sufficient space for the flipping of the frame when the frame is flipped. The power provided by the driving mechanism to the rotation of the two-way screw rod allows the fixation of the frame to be performed without manual adjustment, and the transmission between the sprockets also allows the driving mechanism to avoid the end position of the U-shaped seat, which ensures that the U-shaped plate can adapt to a longer length in the cavity, increases the travel amount of the splint, and allows the splint to act on larger-sized frames without affecting the normal flipping operation of the U-shaped plate.
