According to the utility model, the stress for lifting the climbing frame is mainly concentrated on the frame body part between the lifting machine and the lower lifting hook, and compared with the aluminum alloy climbing frame, the part of the frame body is changed into an all-steel structure, so that most of the frame body is not subjected to internal stress in the lifting process, and the climbing frame is protected; only a single chain is used, so that the possibility of chain clamping of the chain is reduced; the left and right middle hoisting points are alternately used, so that the disassembling process of the calabash is reduced, and the labor intensity is reduced; and the tension of the guide chain can be adjusted through the top damping spring.
Description
Technical Field
The utility model relates to the technical field of building construction lifting tools, in particular to a building climbing frame lifting device.
Background
The climbing frame, also called lifting frame, is a novel scaffold system developed in recent years and mainly applied to high-rise shear wall type building. It can climb up or down along the building. This system makes the scaffold technology completely improved: firstly, the frame does not need to be turned over; and secondly, the scaffold is free from the dismounting and mounting procedures (the scaffold is used until the construction is finished after one-time assembly), and is not limited by the height of a building, so that the manpower and the materials are greatly saved. And the scaffold has great improvement to the traditional scaffold from the safety angle and has great development advantages in high-rise buildings.
For responding to the call of national energy saving and environmental protection, the aluminum alloy climbing frame can slowly replace the full steel climbing frame, the lifting tonnage of the hoist is slowly reduced, and meanwhile, aiming at the performance of the aluminum alloy climbing frame, a specially designed novel hoist head is hung on the ring chain electric hoist which is positioned below the climbing frame. But the rigidity that the frame was climbed to the aluminum alloy is for all steel climbing frame, and rigidity is too low, and traditional just hanging calabash stress point is at the top and the lower extreme of climbing the frame, and when calabash during operation, under the effect of stress, the frame of climbing can be dragged the deformation after long-time, and traditional overhead hoist is difficult to obtain the protection because calabash head is in the below reason.
SUMMERY OF THE UTILITY MODEL
The utility model provides a building climbing frame lifting device aiming at the problems in the prior art.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
the utility model provides a building climbing frame hoisting device, by the lifting machine, go up the stores pylon, about two hoisting points, lead chain and lower lifting hook are constituteed, the first and the second loose pulley of hoist bottom installation respectively, set up screw rod and damping spring in going up the stores pylon, it links to each other with one in hoisting point to lead chain one end ring around the first loose pulley of hoist bottom, it links to each other with another in hoisting point to lead chain another end ring around the third loose pulley on loose pulley second and lower lifting hook upper portion, it links to each other with two about with hoisting points respectively to lead the chain to walk around the loose pulley T of last stores pylon bottom.
When the utility model is used, the hoister is hung under the climbing frame, one middle lifting point is fixed on the middle wall body, the other middle lifting point is not fixed, the lower lifting hook is fixed on the climbing frame, the hoist is positively driven, the lower lifting hook is equivalent to a movable pulley, the climbing frame is slowly lifted under the traction of the guide chain, the travelling block A and the travelling block B are arranged on the left and the right of the elevator, the guide chain is upwards conveyed through the travelling block A during forward rotation, a travelling block T which is equivalent to a fixed pulley is arranged above the guide chain, the travelling block T is connected with the climbing frame through a damping spring, when the climbing frame ascends, the upper end damping spring also drives the loose pulley block to rise, the upper end loose pulley block rotates to adjust the left chain and the right chain, when the climbing frame rises to a certain position, the middle lifting point fixed on the middle wall body is detached from the wall body, the other middle lifting point is installed, the motor is enabled to rotate reversely, the guide chain is conveyed upwards through the traveling wheel B, and the climbing frame continues to be lifted upwards.
The lifting machine head faces upwards, so that the protection is facilitated; the stress for lifting the climbing frame is mainly concentrated on the frame body part between the lifting machine and the lower lifting hook, and compared with the aluminum alloy climbing frame, the part of the frame body is changed into an all-steel structure, so that the majority of the frame body can not be subjected to internal stress in the lifting process, and the climbing frame is protected; only a single chain is used, so that the possibility of chain clamping of the chain is reduced; the left and right middle hoisting points are alternately used, so that the disassembling process of the calabash is reduced, and the labor intensity is reduced; and the tension of the guide chain can be adjusted through the top damping spring.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the working state of the present invention.
In the figure, a lifting machine 1, an upper hanging rack 2, a screw rod 3, a damping spring 4, a lower lifting hook 5, a guide chain 6, a lifting point 7, a free wheel A8, a free wheel B9, a free wheel C10, a free wheel T11 and a climbing frame 12 are arranged.
Detailed Description
As shown in fig. 1 and 2, a building climbing frame lifting device comprises a lifting machine 1, an upper hanging frame 2, a left middle lifting point 7, a right middle lifting point 7, a guide chain 6 and a lower lifting hook 5, wherein the bottom of the lifting machine 1 is respectively provided with a loose pulley A8 and a loose pulley B9, the upper hanging frame 2 is internally provided with a screw rod 3 and a damping spring 4, one end of the guide chain 6 is encircled at the bottom of the lifting machine 1 and the loose pulley A8 is connected with one middle lifting point 7, the other end of the guide chain 6 is encircled at the upper parts of the loose pulley B9 and the lower lifting hook 5 and is connected with the other middle lifting point 7, and the guide chain 6 is encircled at the bottom of the upper hanging frame 2 and is connected with the left middle lifting point and the right middle lifting point respectively.
