Description

Technical Field

[0001] This application relates to the technical field of steel pipe tower welding, and in particular to a welding auxiliary positioning device for steel pipe towers. Background Technique

[0002] As an important infrastructure on transmission lines, steel pipe towers are lattice towers mainly composed of steel pipes for main components and steel pipes or steel sections for other components. It is a support structure for overhead transmission lines to support conductors and lightning conductors. It enables the conductors to meet the clearance requirements for the ground and ground objects, and can bear the loads of the conductors, lightning conductors, and itself, as well as external loads.

[0003] Currently, when manufacturing steel pipe towers, stiffening plates and flange plates need to be welded to both ends of the steel pipes respectively. The steel pipes are large in volume. In the past, they could only be lifted by a crane, and then one or more welders would weld the lifted end of the steel pipe after aligning it with the flange. Since the positions are different, when welding at different positions in the circumferential direction of the steel pipe tower, the position of the steel pipe tower needs to be readjusted. However, when the steel pipe is lifted by a crane, the position adjustment is inconvenient, greatly reducing the production efficiency. Therefore, further improvement is needed. Utility Model Content

[0004] In order to facilitate the adjustment of the position of the steel pipe tower to improve the production efficiency during welding, this application provides a welding auxiliary positioning device for steel pipe towers.

[0005] A welding auxiliary positioning device for steel pipe towers provided by this application adopts the following technical solutions:

[0006] A welding auxiliary positioning device for steel pipe towers includes several bases arranged perpendicular to the length direction of the steel pipe tower body, positioning rollers rotatably connected to the bases, and a first driving member for driving the positioning rollers to rotate. An anti-slip positioning surface is wound around the outer peripheral wall of the positioning rollers. Two positioning rollers are arranged on one base, respectively on both sides of the steel pipe tower body, and the rotation directions of several said positioning rollers are the same.

[0007] By adopting the above technical solutions, due to the provision of the anti-slip positioning surface, it can support when abutting against the steel pipe tower, and under the action of friction, when the first driving member drives the positioning rollers to rotate, it can drive the steel pipe tower to rotate, thereby adjusting the position of the steel pipe tower, so that welders can weld some stiffening plates and flange plates required on the steel pipe tower, that is, it is convenient to adjust the position of the steel pipe tower, and further improve the production efficiency during welding.

[0008] Preferably, one end of the base is provided with a mounting seat for mounting the first driving member. The first driving member includes a driving motor fixedly connected to the mounting seat, a driving rotating shaft coaxially and fixedly connected to the output shaft of the driving motor, a worm gear coaxially sleeved on the driving rotating shaft, and a worm meshing with the worm gear. The worm is coaxially and fixedly connected to the positioning roller.

[0009] By adopting the above technical solution, when the driving motor is started, it drives the driving rotating shaft, the worm gear and the worm to rotate in sequence, so as to drive the positioning roller to rotate, so as to realize the position adjustment of the position on the outer peripheral wall of the steel pipe tower located on the axis. Among them, in order to reduce the possibility of collision between the driving motor directly mounted on the positioning roller and the steel pipe tower, a mounting seat for mounting the driving motor is provided on the base, and the driving rotating shaft, the worm gear and the worm are connected to drive the rotation of the positioning roller.

[0010] Preferably, a protective cover is provided outside the worm gear and the worm.

[0011] By adopting the above technical solution, by providing a protective cover, it can reduce the possibility of accidental contact with the worm gear and the worm and getting injured, and also reduce the possibility of external wear of the worm gear and the worm.

[0012] Preferably, the number of the worm gear, the worm and the positioning roller is the same, and one driving rotating shaft passes through two worm gears.

[0013] By adopting the above technical solution, passing one driving rotating shaft through two worm gears can drive the rotation of two positioning rollers by one driving motor, so as to reduce the cost brought by setting a plurality of driving motors.

[0014] Preferably, it further includes a bracket provided on the base for mounting the positioning roller and a second driving member for driving the bracket to slide along the length direction of the base.

[0015] By adopting the above technical solution, by providing a second driving member, the bracket can be moved along the direction perpendicular to the axis of the steel pipe tower, so as to adjust the horizontal position of the steel pipe tower, or adjust the distance between the two brackets to adapt to the support of different steel pipe towers.

[0016] Preferably, the worm gear is slidably sleeved on the driving rotating shaft. A limiting block is protrudingly provided on the inner peripheral wall of the worm gear. A limiting groove for the limiting block to slidably insert is formed on the outer peripheral wall of the driving rotating shaft along its length direction. The protective cover is provided on the bracket, and limiting balls abutting against the opposite two surfaces of the worm gear are protrudingly provided inside the protective cover.

[0017] By adopting the above technical solution, since the positioning roller slides along the length direction of the base along with the bracket, the corresponding worm and worm gear need to be changed accordingly. Therefore, by setting the cooperation between the limiting block and the limiting groove, and the limiting balls abutting against the opposite two surfaces of the worm, the sliding in the axial direction is restricted, and it can slide along the length direction of the base along with the bracket to adjust the corresponding position.

[0018] Preferably, the bracket includes a sliding plate abutting against the upper surface of the base, a sliding seat fixedly connected to the lower surface of the sliding plate, and two mounting plates vertically arranged on the upper surface of the sliding plate for the positioning roller to be rotatably connected. A sliding groove for the sliding seat to slide is formed on the upper surface of the base along its length direction, and the second driving member is used to drive the sliding seat to slide along the sliding groove.

[0019] Preferably, the second driving member includes a lead screw threadedly passing through the side walls of the sliding seat and the sliding groove and a hand wheel for driving the lead screw to rotate. The length direction of the lead screw is parallel to the length direction of the sliding groove, and one end of the lead screw is far away from the driving motor and the hand wheel is arranged.

[0020] By adopting the above technical solution, by rotating the hand wheel, the lead screw is driven to rotate, so that the sliding seat slides along the length direction of the sliding groove to adjust the relative position of the positioning roller on the base.

[0021] Preferably, one lead screw passes through the two sliding seats.

[0022] By adopting the above technical solution, by passing the lead screw through the two sliding seats, the positions of the two positioning rollers can be adjusted at one time.

[0023] Preferably, a connecting rope (44) is connected between the two brackets (4).

[0024] By adopting the above technical solution, by providing a connecting rope, the position of the base can be changed by lifting with the connecting rope.

[0025] In summary, the utility model has the following beneficial effects:

[0026] 1. Since there is an anti-slip positioning surface, it can support when abutting against the steel pipe tower, and under the action of friction, when the first driving member drives the positioning roller to rotate, the steel pipe tower is driven to rotate, so as to adjust the position of the steel pipe tower, so that welders can weld some stiffening plates and flanges required on the steel pipe tower, that is, it is convenient to adjust the position of the steel pipe tower, and thus the production efficiency during welding is improved.

[0027] 2. By providing a second driving member, the bracket can be moved along the direction perpendicular to the axis of the steel pipe tower, so as to adjust the horizontal position of the steel pipe tower or adjust the distance between the two brackets to adapt to the support of different steel pipe towers.
