DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 , Figure 2 As shown, the utility model provides a steel truss temporary support point operation frame, which is arranged on a foundation 6 and includes a steel structure column, which is fixedly installed at the top center of the foundation 6, and four I-beams 1 are fixedly installed on the top of the foundation 6, and a disc-type scaffolding 2 is fixedly installed on the top of the four I-beams 1. The four disc-type scaffoldings 2 are composed of a plurality of steel pipes arranged in a rectangular shape and fixedly connected. A plurality of layers of wooden springboards 3 are fixedly installed between adjacent surfaces of the four disc-type scaffoldings 2, and inclined reinforcements are fixedly connected between adjacent layers of the wooden springboards 3. The steel pipe 31 can improve the stability between the wooden springboard 3 and the upper and lower parts of the disc-type scaffolding 2. A plurality of temporary iron pedal mechanisms 5 are evenly arranged between the opposite surfaces of the two disc-type scaffoldings 2 in the middle of the top of the foundation 6. One side of the two disc-type scaffoldings 2 on the left and right sides of the foundation 6 is fixedly connected with a steel pipe diagonal brace 4. The steel pipe diagonal brace 4 is connected to the upright part of the disc-type scaffolding 2 through a rotating fastener. The bottom ends of the two steel pipe diagonal braces 4 are fixedly connected to the top of the foundation 6. The outer wall of the steel structure column is provided with a plurality of steel structure support mechanisms 7.

[0024] The foundation of the temporary support point operating frame is made of I-beam 1, and the main structure is a disc-type scaffolding 2 composed of several steel pipes, which is stabilized on the top of the I-beam 1 through a bracket, and a wooden springboard 3 is erected on the top of the disc-type scaffolding 2, and the side of the disc-type scaffolding 2 is supported by a steel pipe diagonal brace 4 to improve stability. The two are connected by a rotating fastener, and a stable foundation is formed by the I-beam 1. A stable main body system is formed by the disc-type scaffolding 2 and the steel pipe diagonal brace 4, and the gap of the disc-type scaffolding 2 cleverly avoids the side support structure of the temporary support point. The operating personnel can rise to the top wooden springboard 3 through the temporary iron pedal mechanism 5 to perform high-altitude welding operations. The I-beam 1 of the temporary support point operating frame can be other types of steel or square steel pipes. Because the frame position and the number of strides of the disc-type scaffolding 2 can be flexibly changed according to actual conditions, the size of the wooden springboard 3 of the upper working platform for operators to operate can be appropriately expanded according to the actual operators, and can be replaced by other materials such as steel fences.

[0025] like Figure 3 , Figure 4As shown, a plurality of temporary iron pedal mechanisms 5 each include two inclined support frames 51, a plurality of horizontal pedal mechanisms 52 are evenly fixedly installed between the opposite surfaces of the two inclined support frames 51, a mounting mechanism 53 is fixedly installed at both left and right ends of the two inclined support frames 51, the horizontal pedal mechanism 52 includes a horizontal foot pedal 521, the front and rear sides of the horizontal foot pedal 521 are respectively fixedly connected to the opposite surfaces of the two inclined support frames 51, a non-slip rubber pad 522 is fixedly installed on the top of the horizontal foot pedal 521, and a plurality of non-slip diamond blocks 523 are evenly fixedly installed on the top of the non-slip rubber pad 522;

[0026] When workers walk on the horizontal pedal mechanism 52, the anti-skid rubber pad 522 on the top of the horizontal pedal 521 and several anti-skid diamond blocks 523 made of rubber material on the surface of the anti-skid rubber pad 522 are used to increase the friction between the workers' soles, so that the workers can walk up and down more stably and safely and avoid slipping due to water.

[0027] like Figure 5 As shown, the installation mechanism 53 includes a steel pipe clamp ring 531, the inner ring of the steel pipe clamp ring 531 is fixedly installed with an anti-skid rubber sleeve 5311, the inner ring of the anti-skid rubber sleeve 5311 is fixedly installed with a plurality of rubber protrusions 5312 in an annular array, the inner ring of the anti-skid rubber sleeve 5311 is clamped with the steel pipe constituting the disc-type scaffold 2, and a positioning box 532 is fixedly installed at the bottom of the steel pipe clamp ring 531 near the movement of the inclined support frame 51, a plurality of compression springs 533 are fixedly installed on one side of the inner wall of the positioning box 532, and a buckle bottom plate 534 is fixedly installed on the other end of the plurality of compression springs 533, and a double-bevel buckle 535 is fixedly installed on the side of the buckle bottom plate 534 away from the compression spring 533, and the other end of the double-bevel buckle 535 penetrates to the inner ring of the positioning box 532 near the steel pipe clamp ring 531 On one side, a limit drive box 536 is fixedly installed at one end of the bottom of the steel pipe clamp ring 531 away from the inclined support frame 51, and a threaded rod 537 is movably installed in the middle of the inner wall of the limit drive box 536 close to the positioning box 532, and the other end of the threaded rod 537 penetrates to the side of the limit drive box 536 away from the steel pipe clamp ring 531 and is fixedly installed with a knob 538, and a movable plate 539 is threadedly installed on the outer wall of the threaded rod 537, and the four side surfaces of the movable plate 539 overlap with the four upper and lower front and rear side surfaces of the inner wall of the limit drive box 536, and two limit long plates 5391 are fixedly installed on the side of the movable plate 539 away from the knob 538, and the other end of the limit long plate 5391 penetrates to the side of the limit drive box 536 close to the steel pipe clamp ring 531 and is located on one side of the double-bevel buckle 535;

[0028] When installing the temporary iron pedal mechanism 5, the steel pipe clamping rings 531 at the upper and lower ends of the inclined support frame 51 included in the temporary iron pedal mechanism 5 can be aligned with the steel pipes that constitute the disc-type scaffolding 2 and clamped downward, so that the steel pipe can use the anti-skid rubber sleeve 5311 and the rubber protrusion 5312 to improve the friction of the steel pipe on the inner ring of the steel pipe clamping ring 531 to maintain stability. At the same time, when clamping, the double-bevel buckle 535 on one side of the positioning box 532 will be squeezed, so that the double-bevel buckle 535 uses the buckle bottom plate 534 to compress the compression spring 533. After the steel pipe is clamped into the inner ring of the anti-skid rubber sleeve 5311, it rebounds and resets, temporarily limiting the bottom of the steel pipe, and then the knob 538 on one side of the limit drive box 536 can be rotated to drive the threaded rod 537 to limit The inner cavity of the positioning drive box 536 rotates, and the threaded connection between the threaded rod 537 and the movable plate 539 is coordinated, so that the two limiting long plates 5391 on one side of the movable plate 539 can be moved toward the double-bevel buckle 535, and finally the bottom of the steel pipe is limited so that the steel pipe is in the inner circle of the steel pipe clamping ring 531, thereby completing the installation of the temporary iron pedal mechanism 5. When disassembling, it is only necessary to reverse the knobs 538 on one side of the limiting drive box 536 at both ends of the two inclined support frames 51 one by one to reverse the threaded rod 537, so that the two limiting long plates 5391 can be retracted into the inner cavity of the limiting drive box 536 to release the limitation on the steel pipe that constitutes the disc-type scaffolding 2, so that the entire temporary iron pedal mechanism 5 can be disassembled, thereby improving the disassembly and assembly efficiency of the temporary iron pedal mechanism 5.

[0029] like Figure 6 As shown, the steel structure support mechanism 7 includes two semi-circular ring chucks 71, and extension plates 72 are fixedly installed on both sides of the opposite surfaces of the two semi-circular ring chucks 71, and a fixing bolt 73 is penetrated between the two extension plates 72 on the opposite sides. Two connecting steel plates 74 are fixedly installed on the opposite back surfaces of the two fixing bolts 73, and a fixing sleeve 75 is fixedly installed on one end of the connecting steel plate 74 away from the semi-circular ring chuck 71, and a pentagonal bolt 76 is threadedly installed on one side of the fixing sleeve 75. The fixing sleeve 75 is fixed to the outer wall of the disc-type scaffolding 2 by the pentagonal bolt 76, and the steel structure column is located between the two semi-circular ring chucks 71.

[0030] When installing the disc-type scaffolding 2, two semi-circular ring chucks 71 connected by connecting steel plates 74 are docked and clamped on the outer wall of the steel structure column, and fixed by using fixing bolts 73 to pass through the extension plate 72 for locking and fixing. At the same time, the fixing sleeve 75 at the other end of the connecting steel plate 74 can also be firmly fixed to the outer wall of the steel pipe included in the disc-type scaffolding 2 by using pentagonal bolts 76, which ultimately improves the stability between the overall operating frame and the steel structure column, so that the entire frame can play the role of supporting the steel structure.

[0031] The working principle of the steel truss temporary support point operating frame is described in detail below.

[0032] like Figure 1-5As shown, the temporary support point operation frame foundation adopts I-beam 1, and the main structure is a disc-type scaffold 2 composed of several steel pipes, which is stabilized on the top of the I-beam 1 through a bracket, and a wooden springboard 3 is set up on the top of the disc-type scaffold 2, and the side of the disc-type scaffold 2 is supported by a steel pipe diagonal brace 4 to improve stability. The two are connected by a rotating fastener, and a stable foundation is formed by the I-beam 1. The disc-type scaffold 2 and the steel pipe diagonal brace 4 form a stable main body system, and the gap of the disc-type scaffold 2 is cleverly avoided. By opening the side support structure of the temporary support point, the operator can ascend to the top wooden springboard 3 through the temporary iron pedal mechanism 5 to perform high-altitude welding operations. When installing the temporary iron pedal mechanism 5, the steel pipe clamping rings 531 at the upper and lower ends of the inclined support frame 51 included in the temporary iron pedal mechanism 5 can be aligned with the steel pipes that constitute the disc-type scaffolding 2 and clamped downward, so that the steel pipes can use the anti-slip rubber sleeves 5311 and rubber bumps 5312 on the inner ring of the steel pipe clamping ring 531 to improve the friction and maintain stability. At the same time, when clamped in, The double-slope buckle 535 on one side of the positioning box 532 is squeezed, so that the double-slope buckle 535 uses the buckle bottom plate 534 to compress the compression spring 533. After the steel pipe is inserted into the inner circle of the anti-slip rubber sleeve 5311, it rebounds and resets to temporarily limit the bottom of the steel pipe. Then, the knob 538 on one side of the limit drive box 536 can be rotated to drive the threaded rod 537 to rotate in the inner cavity of the limit drive box 536, and the threaded connection between the threaded rod 537 and the movable plate 539 can be made to rotate. The two limiting long plates 5391 on the side move toward the direction of the double-slope buckle 535, and finally limit the bottom of the steel pipe so that the steel pipe is in the inner circle of the steel pipe clamp 531, thereby completing the installation of the temporary iron pedal mechanism 5. When the workers walk on the horizontal foot pedal mechanism 52, the anti-slip rubber pad 522 on the top of the horizontal foot pedal 521 and several anti-slip diamond blocks 523 on the surface of the anti-slip rubber pad 522 are used to increase the friction between the workers' soles, so that the workers can walk up and down more stably and safely to avoid slipping on water.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
