Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a posture control device and a control method thereof for a lifting process of an aerial corridor. Background Art

[0002] Sky corridor refers to a connected structure used to connect adjacent building structures. This connected structure is generally connected to adjacent building structures. In the construction of sky corridors, hoisting equipment is usually used to gradually lift the steel structure of the sky corridor upward as a whole, and then connect it with the surrounding structures after the steel structure is in place.

[0003] For the sky corridors between super-high towers, if the sky corridors are constructed as a whole, due to uncontrollable weather changes during the period, if they are subjected to extreme weather conditions such as sudden strong winds, the sky corridors may shake and cause damage. In the prior art, when constructing sky corridors, a lifting device is usually installed on the top of the building, and then the pull ropes of the lifting device are directly connected to the sky corridor for hoisting. However, this hoisting method has shortcomings in actual use. Specifically, when affected by wind, the sky corridor will swing in the air with the length of the pull rope as the radius. Since the length of the pull rope is relatively long, the swing range of the sky corridor is too large, which can easily cause collision damage to the surrounding buildings and the sky corridor itself. That is, the existing hoisting method of the sky corridor is difficult to control the shaking range and posture of the sky corridor in the air, resulting in poor wind resistance during hoisting. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a posture control device and a control method for the lifting process of the aerial corridor, so as to control the aerial posture of the aerial corridor when it is affected by wind force and improve the wind resistance of the aerial corridor during hoisting construction.

[0008] Furthermore, the two pull ropes of the double-drum winch are arranged on both side surfaces of the mounting frame, and fixed pulleys are arranged on both side surfaces of the upper end of the mounting frame, and the two pull ropes are respectively wound around the fixed pulleys.

[0009] Furthermore, a telescopic rod is provided between the first T-shaped connecting block and the second T-shaped connecting block, and the telescopic rod is slidably sleeved on the guide slide bar. Conical cylinders are provided on both ends of the telescopic rod, and conical holes are provided inside the upper slide bar and the lower slide bar at one end facing the telescopic rod. When the two ends of the telescopic rod are respectively pressed against the upper slide bar and the lower slide bar, the conical cylinder is located in the conical hole, and the conical hole squeezes the conical cylinder onto the outer surface of the guide slide bar.

[0010] Furthermore, the telescopic rod comprises an inner rod and an outer rod, the inner rod is threadedly connected to the inner side surface of the outer rod, and the inner rod is sleeved on the guide slide rod.

[0011] Furthermore, both the inner rod and the outer rod are provided with hexagonal annular protrusions.

[0034] like Figure 1 to Figure 7As shown, the present invention is a posture control device for the lifting process of an aerial corridor, including a mounting frame 4, which can be understood as a U-shaped steel plate, and can be assembled in multiple sections. It is designed according to the height of the wall 1, and the mounting frame 4 is fixedly installed on the outer surface of the wall 1 and installed perpendicular to the floor slab 2. A guide slide bar 5 is provided on the mounting frame 4, and an upper slide tube 6 and a lower slide tube 7 are slidably sleeved on the guide slide bar 5. A first T-shaped connecting block 8 is provided on the outer side surface of the upper end portion of the upper slide tube 6, and a second T-shaped connecting block 9 is provided on the outer side surface of the lower end portion of the lower slide tube 7. The first T-shaped connecting block 8 and the second T-shaped connecting block 9 are respectively fixedly connected to the outer sides of the upper slide tube 6 and the lower slide tube 7, and the vertical parts (shorter parts) of the first T-shaped connecting block 8 and the second T-shaped connecting block 9 are arranged to point to the middle part of the adjacent wall 1. The first T-shaped connecting block 8 and the second T-shaped connecting block 9 are arranged to point to the middle part of the adjacent wall 1. Two parallel elastic ropes 18 are provided between the transverse parts (longer parts) of 9, and the two ends of the two elastic ropes 18 are respectively fixed on the two end parts of the transverse parts of the first T-shaped connecting block 8 and the second T-shaped connecting block 9, and the transverse part of the first T-shaped connecting block 8 is connected to the lifting device to drive the upper slide 6 to move on the guide slide bar 5. The vertical ends of the first T-shaped connecting block 8 and the second T-shaped connecting block 9 are respectively provided with a first connecting rope 10 and a second connecting rope 11, one end of the first connecting rope 10 and the second connecting rope 11 are respectively fixed on the vertical ends of the first T-shaped connecting block 8 and the second T-shaped connecting block 9, and the other ends of the first connecting rope 10 and the second connecting rope 11 are both arranged between the first T-shaped connecting block 8 and the second T-shaped connecting block 9, and the other ends of the first connecting rope 10 and the second connecting rope 11 are respectively connected to the upper and lower parts of the aerial corridor 3.

[0035] The working principle of the above technical solution is:

[0036] When the first connecting rope 10 and the second connecting rope 11 are fixed on the aerial corridor 3, under the action of the lifting device, the lifting device will drive the upper slide 6 to move on the guide slide bar 5, and then drive the first connecting rope 10 to move. The movement of the first connecting rope 10 will drive the aerial corridor 3 to move, thereby realizing the lifting operation of the aerial corridor 3. At the same time, it is not difficult to understand that the setting of the elastic rope 18 is mainly intended to connect the upper slide 6 and the lower slide 7 as a whole, and then the elastic rope 18 can be pulled by the movement of the upper slide 6, thereby driving the lower slide 7 to move. This setting The purpose of this method is to ensure that when the aerial corridor 3 is lifted, the traction force on the second connecting rope 11 is small, so as to avoid the oblique force on the second connecting rope 11 (the aerial corridor 3 drives the lower slide 7 to move), which causes the lower slide 7 to be stuck on the guide slide rod 5. At the same time, since the lengths of the first connecting rope 10 and the second connecting rope 11 are relatively short, that is, when the aerial corridor 3 is affected by wind, the swing radius of the aerial corridor 3 can be understood as the length of the first connecting rope 10 and the second connecting rope 11, and thus its swing radius is small, thereby controlling the swing posture of the aerial corridor 3 in the air.

[0037] It is not difficult to understand that, in the above technical scheme, the force of the lifting device is applied in parallel and acts on the central axis of the guide slide bar 5, and thus the direction of the force is parallel to the movement direction of the guide slide bar 5, thereby improving the movement effect of the upper slide 6 and the lower slide 7, and at the same time, the pull rope 15 of the lifting device will not swing with the swing of the aerial corridor 3, thereby reducing the influence of the wind load on the pull rope 15 to a certain extent; it is not difficult to understand that in the present technical scheme, the first connecting rope 10 and the second connecting rope 11 can also be arranged directly below the lifting device by setting ear plates, thereby further improving the lifting effect of the lifting device on the aerial corridor 3.

[0038] At the same time, the first connecting rope 10 and the second connecting rope 11 are used to connect the aerial corridor 3, which facilitates the connection between the aerial corridor 3 and the hoisting part during hoisting, as well as the disassembly after hoisting into place. At the same time, this method can be understood as a soft connection, which can avoid the problem of increased internal stress of the aerial corridor 3 due to uneven lifting length during hoisting.

[0039] In one feasible manner, the lifting equipment includes a double-drum winch 16, which is fixed to the top of the building. The two pull ropes 15 of the double-drum winch 16 are respectively fixed to the two ends of the horizontal part of the first T-shaped connecting block 8. The upper slide is lifted by means of the two pull ropes 15, which can ensure that the traction force is parallel to the movement direction, that is, further improve the traction effect (if the traction force is not parallel, it will cause the upper slide 6 to be subjected to an oblique force, thereby increasing the friction between the upper slide 6 and the guide slide rod 5, affecting the sliding effect).

[0040] In one feasible manner, the two pull ropes 15 of the double-drum winch 16 are arranged on both side surfaces of the mounting frame 4, and fixed pulleys 17 are provided on both side surfaces of the upper end of the mounting frame 4. The two pull ropes 15 are respectively wound around the fixed pulleys 17. The setting of the fixed pulleys 17 can guide the pull ropes 15 and achieve the effect of lifting force.

[0041] In one practicable manner, a telescopic rod is provided between the first T-shaped connecting block 8 and the second T-shaped connecting block 9, and the telescopic rod is slidably sleeved on the guide slide bar 5. Conical cylinders 20 are provided on both ends of the telescopic rod, and conical holes 19 are provided inside the ends of the upper slide bar 6 and the lower slide bar 7 facing the telescopic rod. When the two ends of the telescopic rod are respectively pressed against the upper slide bar 6 and the lower slide bar 7, the conical cylinder 20 is located in the conical hole 19, and the conical hole 19 squeezes the conical cylinder 20 onto the outer surface of the guide slide bar 5.

[0042] When encountering strong winds, the construction workers only need to extend the telescopic rod to adjust the distance between the upper slide 6 and the lower slide 7 to the maximum, and at the same time tighten the second connecting rope 11. The advantage of this is that the first connecting rope 10 and the second connecting rope 11 after tightening will exert a traction force on the aerial corridor 3, so as to control the swing range and position of the aerial corridor 3 in the air, thereby further reducing the swing amplitude of the aerial corridor 3. It is not difficult to understand that because the upper slide 6 and the lower slide 7 are clamped on the guide slide bar 5 under the action of the conical cylinder 20, the upper slide 6 cannot slide under the action of the guide slide bar 5 at this time, so the vertical movement of the aerial corridor 3 can be restricted (it is not difficult to understand that the direction of the wind blows from the side, so when the wind is strong, one end of the aerial corridor 3 may have the problem of vertical deflection and lifting, but the other end will not be lifted at the same time, so the other end is in a clamped state, so the vertical position of the aerial corridor 3 can still be limited).

[0043] In one practicable manner, the telescopic rod includes an inner rod 13 and an outer rod 12, wherein the inner rod 13 is threadedly connected to the inner side surface of the outer rod 12, and the inner rod 13 is sleeved on the guide slide rod 5. This arrangement of the telescopic rod is simple and reliable.

[0044] In one practicable manner, both the inner rod 13 and the outer rod 12 are provided with a hexagonal annular protrusion 14, so that the staff can rotate the inner rod 13 and the outer rod 12 by means of a wrench or the like.

[0045] In one practicable manner, the conical cylinder 20 includes a plurality of annularly distributed arc clips 21, and installation gaps are provided between adjacent arc clips 21, so that the arc clips 21 are easier to deform. At the same time, the purpose of the installation gaps is to provide a range of movement paths for the arc clips 21 to deform.

[0046] In one feasible manner, the mounting frame 4 is disposed in the middle of the window opening 22 of the wall 1, and the mounting frame 4 is fixed to the wall 1 by anchor bolts. This arrangement is convenient for workers to adjust components such as the telescopic rod through the window opening 22 indoors without the need for workers to be suspended in the air for high-altitude operations.

[0047] A control method for a posture control device used in an aerial corridor lifting process includes the following construction steps:

[0048] S1, evenly arrange the aerial attitude control device on the installation wall 1 of the aerial corridor 3, and the installation frame 4 of the aerial attitude control device is arranged on the outer surface of the middle part of the window opening part 22 of the wall 1;

[0049] S2, fixing the first connecting rope 10 and the second connecting rope 11 of the aerial attitude control device to the upper end and the lower end of the aerial corridor 3 respectively;

[0050] S3, start the double-drum winch 16 to drive the upper slide 6 to move on the guide slide bar 5, and then lift the sky corridor 3 upward;

[0051] S4, when strong winds are encountered during the lifting process of the sky corridor 3, the construction personnel operate the telescopic rod to extend at the window opening part 22 of the corresponding floor of the telescopic rod, so that the two ends of the telescopic rod are pressed against the ends of the upper slide tube 6 and the lower slide tube 7. At this time, the first connecting rope 10 and the second connecting rope 11 are in a taut state, and the conical tube 20 provided at the end of the telescopic rod is tightly held on the guide slide rod 5, thereby controlling the aerial posture of the sky corridor 3;

[0052] S5, when the strong wind disappears, the telescopic rod is reset and the sky corridor 3 can be continuously lifted.

[0053] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
