Description

Technical Field

[0001] The present application belongs to the technical field of pipe truss hoisting, and specifically relates to a stabilization control device and a hoisting method for a curved pipe truss structure. Background Art

[0002] In recent years, with the rapid development of my country's economy and construction technology, various forms of steel structures have been widely used in large-space buildings such as stadiums, airports, stations, equipment production lines, theaters in exhibition halls, etc., and tube truss structures, as part of steel structures, have been widely used.

[0003] Tube trusses are increasingly used in current spatial structures. As one of the world's advanced building technologies, large-span building structures are widely used in many aspects of my country's construction. Compared with other building structures, large-span tube truss structures can meet many needs in actual construction, and have great advantages in reducing the amount of steel used and reducing construction costs. Compared with traditional grids, there are fewer rods and beautiful nodes. The traditional ball node connection method is abandoned, simplifying the node structure. Using large-span cross tube truss structures, various light-weight large-span structures can be built. In public civil buildings, especially in the construction of large exhibitions and sports venues, there is a development prospect of widespread promotion and application.

[0004] However, when using a pipe truss structure on a large space roof, for the sake of the beauty of the building, the roof is mostly curved and has a certain curvature, so the pipe truss used in the building is also curved. The existing pipe trusses are hoisted to the top of the building, and then manually adjusted to the correct position and angle before connecting.

[0005] Since the pipe truss is large in size and heavy in weight, and it is difficult for operators to exert force on the roof of a building, adjusting the position of the pipe truss on the roof of a building is time-consuming and laborious, and has certain safety hazards. Summary of the invention

[0006] The technical problem to be solved by the present application is: to overcome the shortcomings of the prior art and provide a stabilization control device and a hoisting method for a curved tube truss structure. The present application adjusts the angle of the tube truss during the connection with the tube truss before hoisting, and there is no need to adjust the angle of the tube truss during the high-altitude installation process, thereby improving the installation efficiency and reducing the safety hazards of high-altitude operations.

DETAILED DESCRIPTION

[0038] In conjunction with the accompanying drawings, a stabilization control device and a hoisting method for a curved tube truss structure of the present application are further described in detail, but this is not intended to limit the present application.

[0039] A stabilization control device for the lifting of a curved tube truss structure, comprising Figures 1 to 11 As shown, it includes an external frame 1, which plays a supporting role and is a rectangular frame. A top plate 101 is fixed in the middle of the top of the external frame 1, and a lifting ring 2 is connected to the top plate 101. The lifting ring 2 is connected to the hook of the crane, so that the crane can lift the entire curved tube truss structure with a stable control device.

[0040] A wire roller 4 is rotatably arranged inside the frame 1, a motor 5 driving the wire roller 4 to rotate is fixed on the outer frame 1, and a sling 28 is wound around the rotating roller 4. The two ends of the sling 28 are connected to a tube truss connection device, which is used to be fixed to a tube truss 29. The tube truss connection device includes two support plates 21 arranged at intervals, and a second telescopic rod 23 is passed between the two support plates 21.

[0041] Depend on Figure 10 to Figure 11 As shown, two second telescopic rods 23 are arranged at intervals between the two support plates 21, and a horizontally arranged top support rod 26 is fixedly connected to the inner side of the two support plates 21. A second telescopic control mechanism 27 is connected between the two top support rods 26, and the second telescopic control mechanism 27 controls the displacement of the two top support rods 26. By expanding the two support plates 21 outward and fixing them with the tube truss 29, the applicability of the tube truss connection device can be improved, and it is convenient to be applicable to tube trusses 29 of different widths.

[0042] The second telescopic control mechanism 27 can drive the top support rod 26 in the following two ways:

[0043] 1. The second telescopic control mechanism 27 adopts a double-head hydraulic cylinder, and the top support rod 26 is fixedly connected to the two hydraulic rods. The second telescopic control mechanism 27 controls the movement of the top support rod 26 by hydraulic means;

[0044] Second, the top support rod 26 is a screw rod, and the two top support rods 26 have different thread directions. The second telescopic control mechanism 27 is a nut sleeve, and the second telescopic control mechanism 26 is sleeved on the top support rod 26, and the two are threadedly connected. By rotating the second telescopic control mechanism 26, the two top support rods 26 are controlled to move in opposite directions.

[0045] The second telescopic control mechanism 27 and the top support rod 26 of this embodiment adopt the second structure. Compared with the first structure, the second structure does not require an additional hydraulic station and is more suitable for outdoor use.

[0046] If the two support plates 21 are only used to squeeze the tube truss 29 outwards for fixed connection, since the entire tube truss 29 is very heavy and there is wind when it is hoisted to a high altitude, the connection between the tube truss 29 and the tube truss connecting device is not strong enough. In order to improve the firmness of the connection between the two, the following technical solution is added in this embodiment.

[0047] The support plate 21 is provided with a vertical slide 2101, and a locking structure 22 is provided inside the vertical slide 2101 for sliding up and down. One side of the vertical slide 2101 is connected with a plurality of inclined slots 2102 arranged at intervals up and down. The locking structure 22 includes an insertion rod 2201, and a ring 2202 is fixed on one side of the insertion rod 2201, and the ring 2202 is connected with the inclined slot 2102.

[0048] An anti-slip disc 2203 is provided at the end of the insertion rod 2201.

[0049] The insertion rod 2201 slides up and down along the vertical slide 2101, and after sliding to the specified position, the insertion rod 2201 is rotated so that the collar 2202 is sleeved inside the oblique slot 2102 to complete the positioning of the insertion rod 2201. During the lifting process of the pipe truss 29, the insertion rod 2201 is cushioned under the side pipe 2901 of the pipe truss 29 to strengthen the support of the pipe truss 29.

[0050] In order to avoid displacement of the pipe truss connection device during the lifting process, a hook 24 is rotatably connected to the second telescopic rod 23. After being installed in place, the hook 24 is hooked on the pipe at the front end of the pipe truss 29.

[0051] The external frame 1 is rotatably connected with a spline shaft 3, the output shaft of the motor 5 is connected to the spline shaft 3, the spline shaft 3 is sleeved with two wire rollers 4 slidably connected thereto, and the ends of the slings 28 on the two wire rollers 4 are respectively connected to each support plate 21.

[0052] At least two parallel spline shafts 3 are rotatably connected to the outer frame 1. The pipe truss 29 is connected by two slings 28 to improve the stability of the pipe truss 29 during the lifting process. At the same time, the wire roller 4 can slide along the spline shaft 3 to make the two slings 28 flush with the two ends of the pipe truss 29, further improving the stability.

[0053] Depend on Figure 3 as well as Figure 5 As shown, the bottom of the external frame 1 is connected with a first telescopic rod 19, and the bottom of the first telescopic rod 19 is hinged with a pressing plate 20. Further, two first telescopic rods 19 are arranged at intervals at the bottom of the external frame 1, and the ends of the two first telescopic rods 19 are hinged with the same pressing plate 20.

[0054] The first telescopic rod 19 is an electric telescopic rod. A power module is fixed on the external frame 1. The power module includes a battery to supply power to the first telescopic rod 19 and the motor 5.

[0055] A method for hoisting a pipe truss, based on the above-mentioned stabilization control device for hoisting a curved pipe truss structure, comprises the following steps:

[0056] S01, insert the two support plates 21 of the tube truss connection device into the inner wall of the tube truss, push the top support rod 26 outward through the second telescopic control mechanism, so that the outer side of the support plate 21 abuts against the inner wall of the side tube 2901 of the tube truss 29, and push the clamping structure 22 outward to move the clamping structure 22 to the bottom of the side tube 2901 to support the side tube 2901;

[0057] S02, start the motor 5 to rotate the wire roller 4, adjust the distance between the two ends of the sling 28 and the wire roller 4, and then adjust the inclination angle of the pipe truss 29 so that its position is the same as the installation angle when it is suspended to the roof;

[0058] S03. After the angle adjustment of the tube truss 29 is completed, the first telescopic rod 19 is extended to make the pressing plate 20 contact the top of the tube truss 29. The pressing plate 20 presses down the tube truss 29 and fixes the tube truss 29 together with the sling 28.

[0059] In order to prevent the sling 28 from moving during the lifting process, in this embodiment, a sling clamping mechanism is provided between the two spline shafts 3. The sling clamping mechanism includes a bottom plate 7, two locking wheels 9 and a control wheel 10. An end plate 6 is vertically provided at the end of the bottom plate 7, and a horizontal slide groove 601 is provided on the end plate 6.

[0060] The two locking wheels 9 are arranged horizontally and spaced apart, and the control wheel 10 is arranged below and between the two locking wheels 9. Figure 6 As shown, the sling 28 abuts against the circumferential surfaces of a locking wheel 9, a control wheel 10 and another locking wheel 9 in sequence, and is guided by the three.

[0061] Two connecting rods 11 are rotatably connected to the rotating shaft of the control wheel 10, and the other ends of the two connecting rods 11 are rotatably connected to the rotating shafts of the two locking wheels 9. A limiting shaft 1101 is convexly arranged in the middle of the connecting rod 11, and the limiting shaft 1101 is inserted into the interior of the horizontal slide groove 601.

[0062] The control wheel 10 is connected to the U-shaped frame 12. The first telescopic control mechanism 18 controls the U-shaped frame 12 to move up and down, thereby driving the control wheel 10 to move up and down. During the movement of the control wheel 10, the two locking wheels 9 are driven to move through the connecting rod 11. When the control wheel 10 moves down, the limit shaft 1101 of the connecting rod 11 slides inside the horizontal slide groove 601, driving the two locking wheels 9 to move toward each other, thereby clamping the sling 28 between the two. In addition to the direction-changing effect of the control wheel 10, the three together clamp the sling 28 to prevent it from moving. When the control wheel 10 moves up, the connecting rod 11 drives the two locking wheels 9 to move in the opposite direction, presenting an open state, releasing the clamping of the sling 28, so that the sling 28 can move freely.

[0063] Since the position of the sling 28 will be adjusted according to the width of the tube truss 29, the position of the corresponding sling clamping mechanism must also be adjusted accordingly. Therefore, the bottom plate 7 is fixedly connected to the wire roller 4 through the connecting plate 8. The U-shaped frame 12 is arranged below the control wheel 10, and a horizontal plate 1201 is fixed inside the U-shaped frame 12. Two horizontal plates 1201 are inserted into the inside of the tube 17. The tube 17 is connected to the telescopic rod of the first telescopic control mechanism 18, and the first telescopic control mechanism 18 is fixedly connected to the top plate 101. In this way, two U-shaped frames 12 can be controlled simultaneously by one first telescopic control mechanism 18.

[0064] In order to ensure that the U-shaped frame 12 can only move up and down, a vertical rod 1202 is fixed to the bottom of the U-shaped frame 12 , and the vertical rod 1202 passes through the through hole of the bottom plate 7 .

[0065] A vertical suspension rod 15 is provided on the top of the end plate 6 , a slideway 102 is provided on the top plate 101 , and the top of the suspension rod 15 passes through the slideway 102 to the top of the top plate 101 and is fixed with a limit plate 16 .

[0066] Two parallel and spaced guide rods 14 and a screw 13 are provided at the bottom of the base plate 7. The screw 13 is threadedly connected to the base plate 7. Both ends of the screw 13 are mounted on the external frame 1. The screw 13 is provided with two threaded portions with opposite rotation directions. The two threaded portions are respectively threadedly connected to the base plate 7. In this way, the spacing between the two sling clamping mechanisms and the wire roller 4 can be adjusted by rotating the screw 13.

[0067] The implementation methods of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
