Description

Technical Field

[0001] The utility model relates to the technical field of transformer oil tank processing, in particular to the field of transformer oil tank welding support equipment, and specifically refers to a height-adjustable anti-dumping type welding support device. Background Art

[0002] As a device that connects networks of different voltage levels, power transformers are an extremely important part of the power system. They are widely used in power generation, transmission, and distribution. As an important part of the transformer, the transformer oil tank protects the transformer. In order to reduce the material cost of the oil tank, the oil tank is generally welded with thin steel plates. In order to control welding deformation, it is necessary to use columns to support the inside during welding to prevent welding deformation and facilitate the control of the inner limit size of the oil tank.

[0003] The application document with application number CN2013102490301 provides a supporting tooling and supporting method for a barrel-type oil tank cover. The device can support the oil tank, but there are also some technical problems. The lengths of the screw and steel pipe in the application document are not adjustable. According to the different heights of the oil tank and different welding requirements, the device needs to be replaced with different heights. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a height-adjustable anti-dumping type welding support device, wherein the height of the support device can be adjusted according to the height required for welding the transformer oil tank, and the support frame can stably support the support device on the ground to prevent the support device from dumping.

[0005] The utility model is realized through the following technical scheme, and provides a height-adjustable anti-dumping type welding support device, comprising an upper support and a lower support, wherein the upper support is connected to the lower support through a thread, the upper support and the lower support are coaxially arranged, a locking gap extending to the upper end surface of the lower support is provided on the upper outer wall of the lower support, the locking gap radially penetrates the lower support, a locking ring is sleeved on the upper part of the lower support, and a locking pin extending to the outer wall of the lower support is threadedly connected to the locking ring.

[0006] The utility model provides an upper support for supporting the transformer oil tank, wherein the upper support is threadedly connected to the lower support, and the height of the upper support can be changed by rotating the upper support, so that the height of the supporting device can be adjusted according to the height required for welding the transformer oil tank. The upper support and the lower support can bear a heavier weight through the threaded connection, and the height can be adjusted more accurately at the same time. The locking pin on the locking ring can press the upper part of the upper support, and the locking gap can provide a certain displacement margin for the deformation of the upper end of the lower support. When the locking pin is tightened, the upper part of the lower support can be pressed against the lower part of the lower support, thereby increasing the friction force and preventing the upper support from rotating.

[0007] As an optimization, a plurality of support frames are installed on the lower pillar, the upper ends of the support frames are connected to the outer wall of the lower pillar, the support frames are inclined and extend outward in the up-down direction, and the lower end surface of the support is flush with the lower end surface of the lower pillar. In the setting of this optimization scheme, the support frames are used to support the lower pillar, and the support frames can play a better supporting role on the lower pillar, making the support more stable.

[0008] As an optimization, a plurality of fixing plates are fixedly connected to the lower support, and the upper end of the support frame is hinged on the fixing plates. The configuration of this optimization scheme enables the support frame to rotate, and when the device is not in use, the support frame can be folded up, which is convenient for the storage and placement of the device.

[0009] As an optimization, a limit pin for limiting the rotation of the support frame is installed on the fixing plate, and the limit pin extends along the axial direction of the fixing plate. In the setting of this optimization scheme, the limit pin can limit the rotation of the support frame to prevent the support frame from being opened at an excessive angle. When the support frame is opened at the maximum angle, the support frame lower end fulcrum and the lower end fulcrum of the lower support are in the same horizontal plane.

[0010] As an optimization, a plurality of operating handles are installed on the upper support, and the operating handles extend along the radial direction of the upper support. The arrangement of this optimization scheme facilitates the rotation of the upper support and the lower support.

[0011] As an optimization, three support frames are provided, and the three support frames are evenly distributed on the lower pillar along the circumference. In the setting of this optimization scheme, the three support frames are evenly distributed along the circumference of the lower pillar, so that the support frames can support the lower pillar in multiple directions, so that the force on the lower pillar is more evenly distributed to each support frame, so that the lower pillar can be more stably supported on the ground.

[0012] As an optimization, the support frame includes a support rod and a connecting handle, the connecting handle is hinged on the fixing plate, and the support rod is fixed on the connecting handle. The setting of this optimization scheme facilitates the hinge connection between the support frame and the fixing plate.

[0013] The beneficial effects of the utility model are as follows: the utility model realizes the height adjustment function of the transformer oil tank welding support device, the anti-dumping function of the support device, and the function of folding and storing, thereby improving the efficiency and safety performance of the oil tank welding support. The utility model realizes the height adjustment of the entire support by adjusting the length of the upper support screwed into the lower support through a thread, and a limit pin is welded on the fixed plate to limit the support frame's opening angle. The support frame is evenly distributed at 120 degrees along the circumference, and when the length meets the maximum opening angle, the lower end fulcrum of the support frame and the lower end fulcrum of the lower support are in the same horizontal plane, thereby realizing stable support of the support. At the same time, the locking pin can lock the upper support to prevent the upper support from rotating during operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] A locking gap 11 extending to the upper end face of the lower pillar is provided on the upper outer wall of the lower pillar, and the locking gap radially penetrates the lower pillar 3. Four locking gaps 11 are provided, and the four locking gaps are distributed along the circumference of the lower pillar. The locking gap is located at the upper part of the lower connecting hole. When the lower pillar is threadedly connected to the upper pillar, the lower end face of the upper pillar is located below the locking gap. A locking ring 9 is provided on the upper part of the lower pillar, and the lower end face of the locking ring is located above the lower end face of the locking gap. A locking pin 10 extending to the outer wall of the lower pillar is threadedly connected to the locking ring, and the locking pin extends radially along the locking ring. Three locking pins are provided, and the three locking pins are evenly distributed along the circumference of the locking ring.

[0022] A plurality of support frames for supporting the lower pillar 3 are installed on the lower pillar 3, the upper ends of the support frames are connected to the outer walls of the lower pillars, the support frames extend outwardly in an inclined manner along the up and down directions, the lower end surfaces of the supports are flush with the lower end surfaces of the lower pillars, a plurality of fixing plates 4 are fixedly connected to the lower pillars, three fixing plates are provided, and the three fixing plates are evenly distributed on the lower pillars 3 along the circumferential direction, the upper ends of the support frames are hinged on the fixing plates 4, so that the support frames are distributed along the circumferential direction of the lower pillars.

[0023] The fixing plate 4 is fixedly connected to the middle section of the lower support, and the fixing plate 4 extends radially along the lower support 3. A mounting hole penetrating the fixing plate is opened on the fixing plate, and the mounting hole extends in a horizontal direction.

The upper end of the support rod is fixedly connected to the lower end of the connecting handle 8. The connecting handle is provided with a hinge hole that passes through the connecting handle horizontally. The hinge hole is coaxially arranged with the mounting hole. The end of the fixing pin 6 away from the mounting hole is rotatably connected in the hinge hole, so that the support frame is hinged to the fixed plate 4.
