Description

Technical Field

[0001] The utility model relates to the field of hoisting and installation of mechanical and electrical pipelines in large steel bent frame factories, and particularly relates to a remote control trolley sliding construction device for mechanical and electrical pipelines in large steel bent frame factories. Background Art

[0002] The transformation and upgrading of automobile industrial factories will inevitably redesign the supporting water and electricity systems according to the production and assembly processes of new energy vehicles, and upgrade the steel roof truss systems in some areas; large automobile factories mostly adopt the steel bent frame structure form, and a large number of building electrical, building water supply and drainage, heating, ventilation and air conditioning, process pipelines, etc. are installed in the steel roof trusses, resulting in a large number of pipelines being installed at the upper ends of the cantilever beams in the steel bent frame structure. Due to the large area of the factory building and the long pipeline routing, a large amount of climbing and hoisting work is required for pipeline installation. However, there is a pair of star-shaped horizontal seismic supports at each place of the cantilever beam of the steel bent frame, resulting in the need to remove this pair of star-shaped horizontal seismic supports first for hoisting pipelines within each axial span, and then restore this pair of star-shaped horizontal seismic supports after the pipeline hoisting is completed, which seriously affects the hoisting and installation efficiency of the pipelines. Content of the Utility Model

[0003] The purpose of the utility model is to provide a remote control trolley sliding construction device for mechanical and electrical pipelines in large steel bent frame factories, which effectively solves the problems of difficult hoisting of a large number of pipelines and low construction efficiency, greatly improves the construction efficiency, and saves time, labor and mechanical costs.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A remote control trolley sliding construction device for mechanical and electrical pipelines in large steel bent frame factories includes pipeline hoisting openings arranged at two wall corners corresponding to the pipeline concentration area, and further includes:

[0006] Two carrying trolleys for carrying the pipelines to be slid;

[0007] Sliding tracks arranged on the cantilever beams of the roof steel bent frame for the carrying trolleys to move;

[0008] An electric hoist arranged under one of the pipeline hoisting openings for pulling the carrying trolley to move from the other hoisting opening to the direction of the electric hoist on the sliding track;

[0009] Two truck cranes located under the roof steel bent frame for hoisting the pipelines to be slid.

[0010] Optionally, the carrying trolley includes a body profile;

[0011] Four rubber directional wheels are respectively arranged at the four corners of the lower end of the body profile for moving on the sliding track;

[0012] At each of the four corners at the upper end of the body profile, a pipe limiter is provided to prevent the pipe from rolling and shifting.

[0013] At the front end of the body profile, a towing hole plate is provided for connection with the towing hanging rope of an electric winch.

[0014] At the middle part of the body profile, there are two hole plates for fixing steel wire ropes to fix the anti - detachment steel wire ropes.

[0015] The anti - detachment steel wire rope fixes the pipe on the carrying trolley through a steel wire rope buckle.

[0016] Optionally, the pipe limiter is an angle steel.

[0017] Optionally, the electric winch is equipped with a control line.

[0018] Optionally, the sling ropes of two said truck cranes are respectively connected to both ends of the pipe to be hoisted.

[0019] Compared with the prior art, the beneficial effects and advantages of the present utility model are as follows:

[0020] 1. According to the characteristics of a steel - structure factory building, with a large length and width span, in the traditional construction plan, one - section horizontal seismic support is removed, a section of pipe is hoisted, and then one - section horizontal seismic support is restored, resulting in low efficiency, many pipe welding joints, and difficult construction period guarantee. Therefore, the construction device is optimally improved, and a construction method of hoisting the pipe at one place and then sliding and welding it on an array - type steel bent is tried.

[0021] 2. By setting the hoisting ports of the pipe at two places, all pipes with three long - side spans can be hoisted, and the crane does not need to frequently change positions, saving a large amount of time and labor for the crane to transfer positions and horizontally transfer the pipe.

[0022] 3. The length of the pipe during hoisting is increased. Without removing the star - shaped horizontal seismic support of each section, only a 3 - meter - long pipe can be hoisted each time. After removal, a 6 - meter - long pipe can be hoisted each time. After adopting the pipe sliding construction device, the hoisting length of the pipe is increased to 12 meters. At the same time, the number of welding operation nodes and the risk points of water leakage are reduced, greatly improving the construction efficiency.

[0023] 4. The length of the pipe is increased. According to the characteristics of a steel - structure factory building, especially the steel bent structure, the longer the pipe, the higher the safety factor of its sliding on the steel bent. Moreover, there are vertical steel - structure supports on the side of the steel bent and star - shaped horizontal supports horizontally. When the pipe slides within the steel bent structure, the longer the pipe, the higher the safety factor, and there is no risk of slipping or falling. Description of the Drawings

[0032] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant accompanying drawings. The present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present utility model more thorough and comprehensive. Embodiment

[0033] An electromechanical pipeline remote control trolley sliding construction device for a large steel bent factory building, as Figures 1 - 6 shown, includes pipeline hoisting openings arranged at two wall corners corresponding to the pipeline concentration area, and further includes: two load-carrying trolleys 1 for carrying the pipeline 9 to be slid; a sliding track 5 arranged on the lower cantilever of the roof steel bent for the load-carrying trolley 1 to move; an electric hoist 11 arranged below one of the pipeline hoisting openings for pulling the load-carrying trolley 1 to move on the sliding track 5 from the other pipeline hoisting opening towards the electric hoist 11; and two truck cranes located below the roof steel bent for hoisting the pipeline 9 to be slid.

[0034] In this embodiment, the carrying trolley 1 includes a body profile 2. At each of the four corners at the lower end of the body profile 2, a rubber directional wheel 4 is provided for moving on the sliding track 5. At each of the four corners at the upper end of the body profile 2, a pipe limiter 3 is provided to prevent the pipe 9 from rolling and shifting. At the front end of the body profile 2, a traction hole plate 10 is provided for connecting with the traction hanging rope 17 of the electric hoist 11. At the middle part of the body profile 2, there are two hole plates 6 for fixing the steel wire rope, which are used to fix the anti-drop steel wire rope 7. The anti-drop steel wire rope 7 fixes the pipe 9 on the carrying trolley 1 through a steel wire rope buckle 8.

[0035] In this embodiment, the pipe limiter 3 is an angle steel; the electric hoist 11 is equipped with a control line 12; the slings of two truck cranes are respectively connected to both ends of the pipe 9 to be hoisted. Embodiment

[0036] This embodiment is the application of the device described in Embodiment 1 in a large steel structure workshop, especially in a steel bent structure, for the rapid hoisting and sliding of mechanical and electrical pipelines on the lower cantilever of the steel bent. The specific operation is as follows:

[0037] Step 1: According to the design characteristics of the large workshop, such as large length and width span, high pipe levelness, long length, and multiple systems, the mechanical and electrical pipelines involve domestic water supply and drainage systems, production water supply and drainage systems, reclaimed water systems, indoor fire hydrant systems, roof rainwater systems, high-pressure fine water mist systems, air-conditioning chilled water pipes, etc. Analyze the drawings and the actual on-site situation, select two intersections corresponding to the areas where the pipes are relatively concentrated, that is, two corners of the wall. After removing the two horizontal seismic supports, the pipes can be slid and constructed towards the three sides through the two intersection points of the three sides.

[0038] Step 2: According to the pipe size, material, and wall thickness information in the drawings, calculate the pipe weight, and select the profile specifications, length, and width dimensions of the carrying trolley 1. For example, select the length and width dimensions of the carrying trolley 1 to be 1200×500 mm. The body profile 2 of the carrying trolley 1 is made of 6# channel steel. At each of the four corners of the body profile 2 of each carrying trolley 1, 4 4-inch rubber directional wheels 4 are equipped and welded. At each of the four corners of the body profile 2 of the carrying trolley 1, a 100-mm-long angle steel (50×50×5 mm) is welded as the pipe limiter 3 to prevent the pipe from rolling and shifting. At the front section of the body profile 2 of the carrying trolley 1, a traction hole plate 10 is welded for the use of the traction hanging rope of the electric hoist 11. At the middle part of the body profile 2 of the carrying trolley 1, there are two hole plates 6 (50×50×5 mm) for fixing the anti-drop steel wire rope 7 of the pipe 9. The anti-drop steel wire rope 7 fixes the pipe 9 firmly on the carrying trolley 1 through a steel wire rope buckle 8, further preventing the pipe from rolling or the risk of falling and hitting people when the trolley derails. As Figure 1 、 Figure 2 shown.

[0039] Step 3: Calculate based on the spacing between the cantilever beams of the steel truss on the steel structure roof of the large factory building, the spacing between the two wheels of the carrier trolley 1, and the weight of the pipeline to be transported, etc., and select the appropriate profile for the pipeline sliding track 5; for example, if the spacing between the cantilever beams of the steel truss is 6.5 meters per bay and the spacing between the wheels of the carrier trolley 1 is 420 mm, select a profile size of 10# channel steel according to this dimension calculation.

[0040] According to the pipeline laying path, two sliding tracks 5 are set on the cantilever beams of the roof steel truss. Select the side parallel to the pipeline 9 to fix the sliding track 5, and set the spacing of the sliding track 5 according to the short-side wheel center distance of the carrier trolley 1. The installation of the sliding track 5 is selected by welding.

[0041] Step 4: According to Figure 3 the pipeline sliding schematic diagram, at the end opposite the lifting port, set an electric hoist 11 to ensure that the pipeline 9 slides along the specified position. The electric hoist 11 should be installed firmly, and the traction force of the electric hoist should be able to meet the weight of the sliding trolley 1 carrying the pipeline.

[0042] For example, for the installed electric hoist 11, a control line 12 (20 meters) of sufficient length should be configured to ensure that the operator 14 can easily control the start and stop of the control switch 13 of the electric hoist on the ground. And the speed is within a reasonable range. As Figure 4 shown.

[0043] Step 5: According to the length (12 meters), size, and weight of the hoisted pipeline 9, two 10t first truck cranes 15 and second truck cranes 16 can be selected.

[0044] The slings of the first truck crane 15 and the second truck crane 16 are respectively fixed at both ends of the hoisted pipeline 9, and the pipeline 9 is slowly lifted. And the head of the pipeline 9 close to the front end has a faster lifting speed by the first truck crane 15, and the tail end has a slower speed by the second truck crane 16, ensuring that the pipeline 9 can be smoothly inserted from the lifting port onto the cantilever beam of the steel truss.

[0045] Step 6: When the front section of the pipeline 9 reaches the position of the carrier trolley 1, the front end of the pipeline 9 can be lowered onto the carrier trolley 1 and fixed with an anti-drop steel wire rope 7, and the first truck crane 15 is withdrawn; as Figure 5 shown.

[0046] The second truck crane 16 continues to slowly lift the tail end of the pipeline 9, and at the same time, push the front section of the pipeline 9 to slowly move forward along the sliding track 5 until the entire 12-meter pipeline 9 is hoisted to the position of the cantilever beam of the steel truss, and the tail end of the pipeline 9 is fixed on the second carrier trolley 1. After tying it firmly, the second truck crane 16 can be withdrawn.

[0047] Step 7: After both ends of the 12-meter-long pipeline 9 are fixed to the carrier trolley 1, confirm that the sliding track 5 is normal and all the rubber directional wheels 4 of the carrier trolley 1 are within the sliding track 5.

[0048] As Figure 6 shown, fix the towing wire rope 15 of the electric hoist 11 to the towing orifice plate 10 of the carrier trolley 1 at the front end of the pipeline 9, tie it firmly, and confirm that there are no obstacles in the driving path. The on-site safety officer conducts a safety inspection to ensure that there are no unauthorized personnel under the sliding track 5. Then, the pipeline sliding operation can start. The safety officer issues a sliding command to the controller 14 of the electric hoist 11. The controller 14 activates the controller switch 13 in his hand. Through the control wire 12 connected to the controller switch 13, the electric hoist 11 drives the towing wire rope 17, towing the carrier trolley 1 together with the pipeline 9 to slide along the sliding track 5.

[0049] Step 8: When the pipeline 9 slides to the corresponding position, the controller 14 stops the electric hoist 11.

[0050] Two lifting vehicles rise simultaneously to the position of the two carrier trolleys 1, and cooperate to unload the pipeline 9 from the carrier trolley 1. Since the length of the pipeline 9 is much greater than the distance between the lower suspension beams, and there are also vertical and diagonal supports around the steel pipe rack, there is no risk of the pipeline slipping or falling.

[0051] Step 9: After all the pipelines in this section have slid to the corresponding positions, all the sliding tracks and electric hoists on this entire section of the workshop can be removed.

[0052] The sliding track and the electric hoist can then be transferred to the other long side of the workshop for the same sliding operation.

[0053] According to the previous BIM plan and the pipeline comprehensive layout CAD drawings, use two lifting vehicles to move the corresponding pipelines to the corresponding positions, and then the pipelines can be preliminarily fixed. Weld the pipelines that need to be welded, and fix and connect the pipelines that need to be connected with clamps.

[0054] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and variations can be made, and these improvements and variations should also be regarded as the protection scope of the present invention.
