Description

Technical Field

[0001] The present invention relates to a construction platform structure, and more particularly to a construction operation platform for high-altitude pipe racks. Background Art

[0002] For the erection of long-distance high-altitude pipelines, pipe supports are usually required to provide support for the pipelines. Such pipe supports include two steel beams arranged in the same plane and parallel to each other. Support beams are arranged at intervals along the length direction between the two steel beams, and both ends of the support beams are fixedly connected to the two steel beams respectively. The support beams are used to support the pipelines. During the process of pipe installation and welding, the difficulty of high-altitude operations is different from that of ground operations in that the operator does not have a suitable construction platform. Currently, the conventional method is to set up scaffolding on the ground or set up double climbing frames on both sides of the steel beams to set up springboards for construction operations. The method of setting up scaffolding not only has high material costs, but also requires a large amount of labor; while for the method of setting up double climbing frames and springboards, every time a section of pipe welding is completed, the construction workers will climb up the steel beams through the climbing frames, and then move and readjust the positions of the climbing frames on both sides respectively, and then climb down from above the steel beams through the climbing frames to the springboards. Such up-and-down operations are likely to consume a large amount of physical strength of the construction workers and reduce the construction efficiency. Summary of the Invention

[0003] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the present invention is: how to provide a construction operation platform for high-altitude pipe racks that is convenient to use, time-saving and labor-saving, and can improve construction efficiency.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A construction operation platform for high-altitude pipe racks includes an operation platform and an adjustment platform located behind the operation platform. The operation platform includes an operation bottom plate extending in the left-right direction. The left and right ends of the operation bottom plate are respectively fixedly connected with front suspension hangers extending vertically upward. The top of the front suspension hanger is bent and extends in the horizontal direction to form a front support hanger. The adjustment platform includes an adjustment bottom plate extending in the left-right direction. The left and right ends of the adjustment bottom plate are respectively fixedly connected with rear suspension hangers extending vertically upward. The top of the rear suspension hanger is bent and extends in the horizontal direction to form a rear support hanger. A layer of rubber pads is adhesively bonded to the bottom surfaces of the front support hanger and the rear support hanger respectively.

[0006] The front support hanger and the rear support hanger are respectively provided with wheel holes extending in the vertical direction. Vertically upward extending guide rods are fixedly connected to the top of the front support hanger and the top of the rear support hanger and are respectively located on the left and right sides of the corresponding wheel holes. A wheel axle extends between the two guide rods in the left-right direction. Guide holes are respectively provided in the vertical direction at the positions of the wheel axle corresponding to the two guide rods on both sides. The wheel axle is sleeved on the corresponding two guide rods through the guide holes on it, and the wheel axle can be slidably engaged with the guide rods in the vertical direction. A roller rotatably connected to the wheel axle is installed on the wheel axle. The lower end of the roller passes through the corresponding wheel hole and can roll on the top of the steel beam to be supported. The upper end of the guide rod is fixedly connected with a top block. A support spring is sleeved on the rod body of the guide rod between the top block and the wheel axle. The two ends of the support spring respectively abut against the top block and the wheel axle. When the operating platform does not carry a load, the corresponding support spring on the operating platform can provide a spring force to push the rubber pad on the front support hanger away from the steel beam to be supported. When the operating platform carries a load, the top block can squeeze its corresponding support spring and the front support hanger is placed on the steel beam to be supported. When the adjustment platform does not carry a load, the corresponding support spring on the adjustment platform can provide a spring force to push the rubber pad on the rear support hanger away from the steel beam to be supported. When the adjustment platform carries a load, the top block can squeeze its corresponding support spring and the rear support hanger is placed on the steel beam to be supported;

[0007] An extension bracket is provided at the rear end of the operating base plate. The extension bracket includes two extension rods located in the same horizontal plane and spaced apart in the left-right direction. The front ends of the extension rods are hingedly connected to the operating base plate through a hinge shaft extending in the left-right direction. A plurality of pedals extending in the left-right direction are spaced apart in the length direction of the two extension rods between the two extension rods. The left and right ends of the pedals are respectively fixedly connected to the two extension rods. An adjustment through hole is provided in the front-rear direction on the adjustment base plate corresponding to the position of the extension bracket. The extension bracket passes through the adjustment through hole and is placed on the adjustment through hole. A limiting block is fixedly connected to the end of the extension rod located behind the adjustment base plate. The limiting block can abut against the rear end of the adjustment base plate to limit the extension rod. A traction rope fixedly connected to them is provided between the operating base plate and the adjustment base plate.

[0008] In the present invention, during use, the operation platform is hung on the steel beams on both sides of the pipe support through the front support hanger, and the adjustment platform is hung on the steel beams on both sides of the pipe support through the rear support hanger, and is respectively supported on the steel beam by rollers. Then, the construction workers stand on the operation bottom plate to perform welding operations on the upper pipe. The construction workers, as the load, are located on the operation platform. Therefore, the operation platform is subject to a downward load, causing the front support hanger to move downward and abut against the steel beam. At the same time, the top block compresses the support spring. Since the front support hanger abuts against the steel beam, the friction between them becomes larger and the rollers no longer move. Therefore, the entire operation platform is placed on the two steel beams, facilitating the construction workers to carry out operations. When the steel pipe welding at this time is completed and it is necessary to move forward to the next welding station, the construction workers pull the adjustment platform through the towing rope. Since the adjustment platform has no load, the support spring pushes the rear support hanger away from the steel beam. With the rollers as the support, when pulling the adjustment platform, the rollers can roll on the steel beam, facilitating the movement of the entire adjustment platform. After the adjustment platform approaches the operation platform, the construction workers directly transfer to the adjustment platform. At this time, the operation platform has no load, while the adjustment platform has a load. The front support hanger is pushed away from the steel beam by the support spring, and the rollers can move, while the rear support hanger is pressed down by the load and placed on the steel beam, so that the adjustment platform cannot move, facilitating the construction workers to carry out subsequent operations. The construction workers push the extension bracket forward on the adjustment platform, so that the entire operation platform can be pushed forward on the steel beam until the limit hole abuts against the rear end of the adjustment bottom plate for limiting. After that, the construction workers transfer to the front adjustment bottom plate again through the pedal on the extension bracket, completing the change of the construction position and finally moving to the corresponding position. The construction workers, as the load, can make the operation platform or adjustment platform where they are located firmly placed on the steel beam, while the unloaded operation platform or adjustment platform can be easily moved through the rollers, reducing the work burden on the construction workers, and the operation is simple and convenient, improving the construction efficiency.

[0009] As an optimization, vertically upward extending front connecting rods are fixedly connected to the rear end of the upper surface of the operation bottom plate and respectively corresponding to the positions of the two extension rods. Two vertically upward extending rear connecting rods are respectively fixedly connected to the front end of the upper surface of the adjustment bottom plate and behind the two front connecting rods. The number of the towing ropes is two. One end of each towing rope is fixedly connected to the top of the front connecting rod, and the other end of the towing rope is fixedly connected to the top of the rear connecting rod corresponding to the rear of the front connecting rod. When the limit block abuts against the rear end of the adjustment bottom plate, the towing rope is in a straightened state.

[0010] When construction workers stand on the adjustment base plate and push the operation platform forward, the towing ropes will gradually straighten. After the limit blocks abut against the adjustment base plate, the towing ropes are completely straightened. At this time, the two towing ropes are respectively located on both sides of the extension bracket. In this way, when construction workers pass through the extension bracket, the two towing ropes will still provide protection for the construction workers.

[0011] As an optimization, a construction leaning device is arranged on the operation base plate. The construction leaning device includes a vertically arranged leaning rod. A support plate extending in the left-right direction is horizontally arranged below the leaning rod. The lower end of the leaning rod is fixedly connected to the middle position of the upper surface of the support plate. A plugging rod arranged on the same center line as the leaning rod is fixedly connected to the lower surface of the support plate. The cross-sectional shape of the plugging rod is a regular polygon. A slide rail extending in the left-right direction is arranged in front of the leaning rod. The rear side surface of the slide rail is fixedly connected to the front side surface of the top of the rod body of the leaning rod. The connection position between the leaning rod and the slide rail is located at the middle position of the slide rail along the length direction of the slide rail. A sliding seat is arranged on the front side surface of the slide rail. The sliding seat is slidably connected to the slide rail and can slide along the extension direction of the slide rail. A leaning plate is arranged in front of the sliding seat. The front surface of the leaning plate is a leaning surface and is arranged obliquely forward above the sliding seat. The back surface of the leaning plate is fixedly connected to the sliding seat. A plurality of plugging holes extending in the vertical direction are uniformly spaced in the left-right direction on the operation base plate. The cross-sectional shape of the plugging holes is the same as the cross-sectional shape of the plugging rod. The plugging rod is inserted into any one of the plugging holes and can slide in cooperation with the plugging holes in the vertical direction. The support plate abuts against the upper surface of the operation base plate. The length of the slide rail is less than the distance between adjacent two plugging holes.

[0012] Since the operation platform is located below the pipe support, during the construction of pipe welding by construction workers, they have been in a standing state all the time. Standing for a long time will cause a burden on the bones and muscles, increase the stress on the lower limb joints, and cause damage to the joints. To solve this problem, the present invention provides a construction leaning device. During construction, the plugging rod below the leaning rod is inserted into the corresponding plugging hole according to the construction position to limit and fix the leaning rod. In this way, when construction workers are standing for construction, their buttocks can lean on the leaning plate, and the body is supported by the leaning plate, reducing the pressure on the lower limbs of the human body. During construction, construction workers can also use their buttocks to horizontally move the leaning plate to adjust the position within a certain range to meet the construction requirements.

[0013] As an optimization, side guard plates are respectively fixedly connected to the left and right sides of the leaning surface of the leaning plate. The two side guard plates are parallel to each other and perpendicular to the extension direction of the slide rail. A leaning space is formed between the two side guard plates and the leaning plate. The side guard plates on both sides can support the waist of construction workers. At the same time, when the leaning plate is horizontally moved, the waist of construction workers can also push the side guard plates to move the leaning plate.

[0014] As an optimization, the leaning rod includes an adjustable outer tube arranged vertically, the bottom of the adjustable outer tube is fixedly connected to the support plate, the tube body of the adjustable outer tube is provided with an adjusting bar hole connected to the inner hole of the adjustable outer tube along the length direction of the adjustable outer tube, the top of the adjustable outer tube is provided with an adjusting inner rod, one end of the adjusting inner rod is inserted into the inner hole of the adjustable outer tube and can slide with the adjusting outer tube along the center line direction of the adjustable outer tube, the other end of the adjusting inner rod is fixedly connected to the slide rail, the rod body of the adjusting inner rod and the position of the adjusting bar hole are concavely provided with an adjusting screw hole along the radial direction of the adjusting inner rod, the adjusting outer tube is provided with an adjusting bolt, the rod of the adjusting bolt passes through the adjusting bar hole and is threadedly engaged in the adjusting screw hole so that the head of the adjusting bolt is locked on the adjusting outer tube. Due to the different heights of different construction workers, the positions of their buttocks are also different. By adjusting the lifting and lowering of the inner rod and using the locking of the adjusting bolt, the height of the leaning board can be adjusted to meet the use requirements.

[0015] Compared with the prior art, the present invention has a simple structure and is easy to use, which makes it convenient for construction workers to move to construction positions at high altitudes, reduces the workload on construction workers, and improves construction efficiency.
