Description

A supporting device for busbar welding

Technical field:

The utility model relates to a supporting device for bus pipe welding.

Background technique:

If an automatic welding machine is used to weld the butt joints of several pipe fittings, after each butt joint is welded, the welded pipe fittings need to be moved axially so as to carry out the welding of the next butt joint.

At present, the commonly used method for moving pipe fittings is to use cranes to move them, which limits the use of automatic welding machines for butt welding of pipe fittings indoors. If an automatic welding machine with high welding quality is also used to weld the busbar pipes at the field electric power engineering construction site, the first thing encountered is the axial displacement of the pipe fittings during welding.

Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art.

Invention content:

The purpose of the utility model is to provide a support device for busbar pipe welding which can axially move the welded pipe fittings at a welding place.

In order to achieve the above object, a supporting device for busbar pipe welding includes a main bracket, a rotating roller bracket, a rotating transmission mechanism, a lifting mechanism and at least one rotating roller, and the rotating roller bracket is connected to the main bracket by sliding up and down. The lifting mechanism is arranged on the main support and connected with the rotating roller bracket, the rotating transmission mechanism is arranged on the rotating roller bracket, and the rotating roller is rotatably supported on the rotating roller bracket and connected with the rotating transmission mechanism.

In order to fit well with the round tube-shaped busbar, the roller surface of the rotating roller is a V-shaped tapered surface.

Further, the rotation transmission mechanism includes a motor and a reduction gear box, the input shaft of the reduction gear box is connected to the motor, and the output shaft is connected to the rotation shaft of the rotating roller.

Further, the main support is a substantially rectangular box, at least one guide hole is provided on the upper surface of the box, and a guide rod adapted to the diameter of the guide hole is provided at the lower end of the rotating roller bracket, and the guide rod Plugged into the guide hole.

Further, the two shaft ends of the rotating roller are respectively rotatably supported on the rotating roller bracket through bearing seats.

After the butt welding of the bus pipe is completed, the rotating roller in the utility model is driven up by the elevator. After the bus pipe is lifted to a certain height, the rotating roller actively rotates to make the bus pipe move axially along the tangential direction of the rotating roller. The utility model thus produces such beneficial effects: it is not restricted by the construction site, occupies a small space, has a simple structure, and is convenient for transportation.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the bracket device of this embodiment has a main bracket 11 that is roughly in the shape of a rectangular box. Other parts in the bracket device use the main bracket 11 as the main body for installation and connection. Mounting holes 113 are provided on the top, so as to be connected with the anchor bolts on the corresponding mounting surface, so that the bracket device is in a stable state.

As shown in Figure 2, the two shaft ends of the rotating roller 131 are rotatably supported on the rotating roller bracket 12 through the bearing housings 122 and 123 respectively. The surface of the roller is a V-shaped tapered surface 1311 . The rotation of turning roller 131 is driven by turning transmission mechanism 15, and this turning transmission mechanism 15 comprises motor 152 and reduction gear box 153, and the input shaft of reduction gear box 153 links to each other with motor 152, and the output shaft is connected with the rotating shaft of turning roller 131.

As shown in Figure 3, the rotating roller bracket 12 is placed on the upper end surface of the above-mentioned main bracket 11, and the upper end surface of this side is provided with two guide holes 111, and two guide rods 121 are arranged at the corresponding position of the lower end of the rotating roller bracket 12, and the two guide rods 121 are respectively inserted into the corresponding guide holes 111, so that the rotating roller bracket 12 is connected to the main bracket 11 in a sliding manner up and down.

Meanwhile, the lower end of the lift bracket 12 is connected with the lift hook 14, which is placed in the main support 11 and includes a screw mandrel 141, a nut 142, a motor and a worm drive unit 143. The worm gear unit 143 is the worm gear reducer, the input end of the worm gear unit 143 is the shaft of the worm 1431, which is connected to the shaft of the motor, and the output end of the worm gear unit 143 is the shaft of the worm wheel 1432 . The nut 142 is arranged at the position of the rotation center of the worm wheel 1432. In this embodiment, the nut 142 and the worm wheel 1432 are integrated, that is, a screw hole corresponding to the nut 142 is set at the center of the worm wheel 1432 body, and the screw rod 141 is screwed into the screw hole. In the screw hole, and the upper end is connected to the lifting bracket 12. Driven by the motor, the worm gear 1431 drives the worm gear 1432 to rotate, and the screw mandrel 141 screwed in the central screw hole of the worm gear 1432 moves up and down under the action of the thread, driving the elevating bracket 12 to move up and down on the main bracket 11.

The utility model can also replace the elevator hook 14 in the above-mentioned embodiment to form a second embodiment.
