Description

Technical Field

[0001] This utility model belongs to the field of lattice column welding technology, specifically an adjustable lattice column welding platform. Background Technology

[0002] Lattice columns are a common structural form with strong bending resistance in building construction. They are mainly composed of reinforced concrete or steel sections and have the characteristics of high strength and small cross-section. They can be used as frame columns for factory buildings, deep foundation pit support, and reverse construction methods.

[0003] Existing lattice column welding platforms are prone to deformation after welding, resulting in large angular errors between lattice columns and affecting normal use. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable lattice column welding platform to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides an adjustable lattice column welding platform, including a welding table. An adjusting screw is rotatably connected to the inner wall of the welding table via a bearing. An adjusting handwheel is fixedly connected to one end of the adjusting screw. A connecting slider is threadedly connected to the outer wall of the adjusting screw. Adjusting support rods are hinged to both ends of the connecting slider. An adjusting rod is hinged to one end of the adjusting support rod. A positioning seat is fixedly connected to the top end of the adjusting rod. A limit groove is provided at the connection between the welding table and the positioning seat. A pointer is fixedly connected to one end of the positioning seat. A scale is fixedly connected to one side of the pointer at the top of the welding table.

[0006] Based on the above structure, rotating the adjusting handwheel causes the connecting slider to slide along the inner wall of the welding table via the adjusting screw. The sliding of the connecting slider causes the adjusting rod to rotate via the adjusting support rod. The rotation of the adjusting rod causes the positioning seat to slide along the groove of the limiting slide, rotating the pointer at one end of the positioning seat to the predetermined angle of the scale, thereby realizing the rapid adjustment of the welding angle of the lattice column.

[0007] Preferably, the adjusting rod forms a rotating structure with the welding table through the connecting slider and the adjusting support rod. There are two sets of adjusting rods, and the rotation centers of the two sets of adjusting rods coincide. In this embodiment, the connecting slider slides through the adjusting support rod to drive the adjusting rod to rotate, thereby realizing the rotation operation of the adjusting rod.

[0008] Preferably, the positioning seat is parallel to the adjusting rod. In this embodiment, this facilitates the adjustment rod to rotate and drive the positioning seat to slide along the groove of the limiting slide.

[0009] Preferably, the scale is semi-circular in shape, and the center of the scale coincides with the rotation center of the adjusting rod. In this embodiment, the pointer at one end of the positioning seat rotates to a predetermined angle of the scale to achieve rapid adjustment of the welding angle of the lattice column.

[0010] Preferably, a positioning frame is fixed to the top of the positioning seat. A clamping screw is rotatably connected to the inner wall of the positioning frame via a bearing. A clamping handwheel is fixedly connected to one end of the clamping screw. A threaded slider is threadedly connected to the outer wall of the clamping screw. Positioning support rods are hinged to both ends of the threaded slider. A sliding base is hinged to one end of the positioning support rod. A guide groove is provided at the connection between the positioning frame and the sliding base. A clamping plate is fixedly connected to the top of the sliding base. A pad is fixedly connected to one end of the clamping plate. In this embodiment, the rotation of the clamping handwheel drives the threaded slider to slide along the inner wall of the positioning frame via the clamping screw. The sliding of the threaded slider drives the sliding base to slide along the groove of the guide groove via the positioning support rod. The sliding base drives the pad to fit against the outer wall of the steel plate via the clamping plate. Similarly, the steel plates of another set of lattice columns are positioned and clamped to prevent deformation of the lattice columns after welding.

[0011] Preferably, the clamping plate has an "L" shaped cross-section. In this embodiment, by setting a clamping plate with an "L" shaped cross-section, it is beneficial for the threaded slider to slide through the positioning support rod and drive the sliding base to slide along the guide groove. The sliding base drives the clamping plate to slide synchronously, thereby realizing the stable sliding operation of the clamping plate.

[0012] Preferably, the clamping plate and the pad are arranged in a "T" shape. In this embodiment, the sliding base drives the pad to fit against the outer wall of the steel plate through the clamping plate. By setting the clamping plate and the pad in a "T" shape, it is beneficial to increase the contact area between the pad and the steel plate and improve the stability of the pad clamping.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model is equipped with an adjustment rod. By rotating the adjustment handwheel, the connecting slider is driven to slide along the inner wall of the welding table through the adjustment screw. The sliding of the connecting slider drives the adjustment rod to rotate through the adjustment support rod. The rotation of the adjustment rod drives the positioning seat to slide along the groove of the limiting slide, and rotates the pointer at one end of the positioning seat to the predetermined angle of the scale, so as to realize the rapid adjustment of the welding angle of the lattice column.

[0015] 2. This utility model is equipped with a clamping plate and a pad. By rotating the clamping handwheel, the threaded slider is driven to slide along the inner wall of the positioning frame through the clamping screw. The sliding of the threaded slider drives the sliding base to slide along the groove of the guide slide through the positioning support rod. The sliding base drives the pad to fit against the outer wall of the steel plate through the clamping plate. Similarly, the steel plate of another set of lattice columns is positioned and clamped.

One side of the pointer 9 is located at the top of the welding table 1 and is fixedly connected to a scale 10.

[0024] Based on the above structure, rotating the adjusting handwheel 3 causes the connecting slider 4 to slide along the inner wall of the welding table 1 via the adjusting screw 2.

[0025] In one embodiment, the adjusting rod 6 forms a rotating structure with the welding table 1 by connecting the slider 4 and the adjusting support rod 5. There are two sets of adjusting rods 6, and the rotation centers of the two sets of adjusting rods 6 coincide.
