Description

Technical Field

[0001] The present application relates to the technical field of tire frames, and specifically discloses a tire frame for H-beam welding and assembly. Background Art

[0002] A tire frame is a mold, which refers to a scaffolding that mainly bears loads. It is a special process equipment for facilitating the assembly and welding of mechanical equipment. It is widely used in formwork engineering, steel structure installation engineering, and bridge engineering. Different from the commonly used single-row and double-row scaffolding, the design of the tire frame varies greatly due to the great differences in the structural form and weight of the support. Different equipment and different processes have different forms of tire frames;

[0003] New steel structure buildings are a trend in modern architecture. Steel structure is a structure mainly composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welding, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. H-shaped steel is an economical section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight. It is widely used in prefabricated building structures of steel structures. H-shaped steel usually consists of two parts: a web and a flange plate. The web and the flange plate are arranged at right angles. Therefore, H-shaped steel has good bending resistance in all directions;

[0004] H-beams need to be assembled by welding, mainly welding the web and flange plates. At present, the welding of H-beams is mainly done manually on the ground, or some simple assembly devices are used, which are generally only suitable for the assembly of H-beams of one specification and can only be used for the assembly of steel plates of fixed thickness. When making H-beams of different specifications or using steel plates of different thicknesses, it is necessary to prepare multiple sets of assembly tools, which is very troublesome, difficult to meet the precision requirements, and has low efficiency.

[0005] In view of this, the inventor proposes a tire frame for H-beam welding assembly. Utility Model Content

[0006] The utility model aims to solve the problem that the conventional H-beam welding lacks a universal fixing tool, thereby making the welding of H-beams of different specifications more troublesome.

[0007] In order to achieve the above object, the utility model provides the following basic solutions:

[0008] A tire frame for H-beam welding assembly, comprising symmetrically arranged mounting blocks, a connecting shaft arranged between the mounting blocks, a mounting platform arranged at the bottom of the mounting blocks, a cylinder arranged on the mounting platform, and a placement plate arranged at the protruding end of the cylinder;

[0009] The connecting shaft comprises an optical axis and a first threaded shaft and a second threaded shaft coaxially connected at two ends of the optical axis, the threads on the first threaded shaft and the second threaded shaft are arranged in opposite directions, the first threaded shaft and the second threaded shaft are threadedly connected with sliding blocks, and a stabilizing rod is further arranged between the mounting blocks and passes through the sliding blocks;

[0010] The sliding block is provided with a fixing assembly for fixing the flange plate, and one of the mounting blocks is provided with a driving assembly rotatably connected to the driving connecting shaft.

[0011] The principles and effects of this basic solution are:

[0012] 1. Compared with the prior art, the device has a simple structure and an ingenious design. The device is provided with a fixing component, which is used to fix the web.

[0013] 2. Compared with the prior art, the device is provided with an installation platform, and a cylinder is designed based on the installation platform. The cylinder can move the placement plate up and down, and the up and down movement of the placement plate can move the web up and down. The up and down movement of the web can change the relative position of the web and the flange plate when they contact, and then reasonably change the welding position, so that the welding position can be controlled manually, the operation is relatively simple, and it is also relatively convenient to use.

[0014] Furthermore, the driving assembly includes a connecting rod and a rotating handle, the connecting rod passes through the mounting block and is coaxially connected to the connecting shaft, and the rotating handle is coaxially connected to the connecting rod.

[0015] Furthermore, the fixing assembly includes a concave plate fixedly connected to the sliding block, a scale arranged on the side of the concave plate and a fixing hole arranged on the top of the concave plate, and a positioning column that can contact the flange plate can be inserted into the fixing hole.

[0016] Furthermore, the lowest height of the placement plate is higher than the height of the sliding block when it moves horizontally.

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0022] The figure marks in the drawings of the specification include: support column 1, support plate 2, mounting block 3, rotating handle 4, sliding block 5, concave plate 6, fixing hole 7, cylinder 8, web 9, stabilizing rod 10, connecting shaft 11, and placement plate 12.

[0023] Implementation example Figure 1 and Figure 2 As shown:

[0024] A tire frame for H-beam welding assembly, comprising symmetrically arranged mounting blocks 3, a connecting shaft 11 arranged between the mounting blocks 3, a mounting platform arranged at the bottom of the mounting blocks 3, a cylinder 8 arranged on the mounting platform, and a placement plate 12 arranged at the protruding end of the cylinder 8;

[0025] The connecting shaft 11 includes an optical axis and a first threaded shaft and a second threaded shaft coaxially connected at both ends of the optical axis, the threads on the first threaded shaft and the second threaded shaft are arranged in opposite directions, the first threaded shaft and the second threaded shaft are threadedly connected with a sliding block 5, and a stabilizing rod 10 is also arranged between the mounting blocks 3 and passes through the sliding block 5;

[0026] The sliding block 5 is provided with a fixing assembly for fixing the flange plate, and one of the mounting blocks 3 is provided with a driving assembly for rotationally connecting the driving connecting shaft 11 .

[0027] Specifically: the driving assembly includes a connecting rod and a rotating handle 4, the connecting rod passes through the mounting block 3 and is coaxially connected to the connecting shaft 11, the rotating handle 4 is coaxially connected to the connecting rod, and the fixing assembly includes a concave plate 6 fixed to the sliding block 5, a scale arranged on the side of the concave plate 6 and a fixing hole 7 arranged on the top of the concave plate 6, and the fixing hole 7 can be inserted with a positioning column that can contact the flange plate.

[0028] The lowest height of the placement plate 12 is higher than the height of the sliding block 5 when it moves horizontally, so as to avoid movement interference between the sliding block 5 and the placement plate 12. The mounting platform includes a support column 1 fixedly connected to the bottom of the mounting block 3 and a support plate 2 arranged between the support columns 1, and the cylinder 8 is installed on the support plate 2.

[0029] Specific implementation process:

[0030] In the first step, the web 9 is installed first. The web 9 is placed on the placement plate 12. The web 9 does not need to be absolutely neat and a slight tilt is allowed.

[0031] The second step is to install the flange plate, insert the flange plate horizontally into the concave plate 6, and the bottom of the flange plate contacts the bottom of the concave plate 6. The flange plate can be of suitable thickness and length, as long as the length does not exceed the concave length of the concave plate 6. If the flange plate is shorter than the concave length of the concave plate 6, a positioning column is required. The positioning column is inserted into the fixing hole 7 to fix the flange plate to prevent the flange plate from shaking.

[0032] The third step is to find the center point of the flange plate by using a scale, start the cylinder 8, and stop starting the cylinder 8 after the web plate 9 and the center point of the flange plate are kept flush;

[0033] The fourth step is to rotate the rotating handle 4, so that the two concave plates 6 move toward each other and approach each other, gradually making the flange plate contact with the web plate 9, and then continue to rotate the rotating handle 4 to make the web plate 9 contact with the flange plate more closely;

[0034] The fifth step is to weld the contact position between the web 9 and the flange plate. After welding, remove the positioning column, pull out the H-shaped steel to be formed, and then change the surface to weld the contact position between the web 9 and the flange plate. At this point, the welding of the H-shaped steel is completed.

[0035] The device solves the problem that conventional H-beam welding lacks a universal fixing tool, which results in troublesome welding of H-beams of different specifications.
