Description

Technical Field

[0001] The present invention relates to the technical field related to construction engineering, and specifically relates to a device for lifting precast components. Background Art

[0002] In construction engineering, in order to reduce the time and labor costs of on-site operations, precast components are prefabricated in a factory and then assembled at the construction site. When assembling these building precast components, a lifting device is required to lift the precast components. However, existing building lifting devices still have deficiencies. For example;

[0003] (1) Most existing building lifting devices use ropes for lifting. When using ropes for lifting, due to the flexibility of the ropes, when lifting precast components, due to the inertia of the lifting movement and the influence of wind, the precast components being lifted will swing, which easily leads to potential safety hazards.

[0004] (2) Traditional lifting devices mostly use clamps to clamp and fix precast components. Since precast components have different shapes, such as serrated on both sides, cylindrical, block-shaped, etc., when traditional clamps encounter precast components with irregular shapes on both sides, although they can clamp, the squeezing force of the clamping plates will damage the tips of the irregular shapes on both sides of the precast components, affecting the quality of the precast components after lifting.

[0005] (3) The adjustment of the lifting mechanism of existing lifting devices is not convenient enough. When encountering precast components with a relatively wide size or requiring horizontal clamping and lifting, it is difficult for traditional lifting mechanisms to quickly adjust and adapt. Moreover, after the lifting mechanism lifts the precast components, it is difficult to rotate and adjust the position in the air.

[0006] Therefore, we propose a device for lifting precast components to solve the problems raised above. Summary of the Invention

The other end of the second two-way air pump 2712 is communicated with the other side of the airbag 2708 through a suction pipe 2714. By using the two fixing components 27 moving towards each other, the fixing rod 2710 on the side plate 2707 inside the fixing plate 2706 can be made to fit on the surface of the building precast component. At the same time, in cooperation with the use of the second two-way air pump 2712, the airbag 2708 can be made to squeeze the fixing rod 2710 so that the fixing rod 2710 fits on the surface of the irregular precast component, facilitating the fixing of the fixing component 27 to precast components of different shapes. Above the rotating disk 22, a connecting block 29 that penetrates through the middle of the fixing disk 21 is fixed. Tooth blocks 30 are uniformly fixed on the surface of the connecting block 29.

[0053] Please refer to Figure 9 , Figure 11 and Figure 13, a limiting component 32 is installed on the outer surface of the vertical column 2701. The limiting component 32 includes a limiting frame 3201, a clamping rod 3202, a third spring 3203, an opening 3204 and a lifting block 3205. The clamping rod 3202 is slidably connected inside the limiting frame 3201, and the clamping rod 3202 is connected to the inside of the limiting frame 3201 through the third spring 3203. An opening 3204 is formed on the surface of the limiting frame 3201. The upper end of the clamping rod 3202 is fixed with a lifting block 3205 protruding from the opening 3204. The clamping rod 3202 and the clamping hole 2711 on the surface of the limiting nut 2705 form a clamping connection. The limiting of the movable shaft 2704 can be facilitated by the clamping of the clamping rod 3202 on the limiting component 32 and the clamping hole 2711 on the limiting nut 2705 on the surface of the movable shaft 2704 below the vertical column 2701, so as to position the fixing plate 2706 at the end of the movable shaft 2704 during use.

[0054] Working principle: First, during use, the positions of the two sets of fixing components 27 on the cross-frame assembly 26 are adjusted according to the width of the precast component. During adjustment, the sliding frame 2702 above the vertical column 2701 is combined with the mounting hole 2604 on the surface of the sliding plate 2603 inside the upper frame plate 2601 of the cross-frame assembly 26 through the second mounting bolt 2703, so as to facilitate the use of the fixing plate 2706 below the vertical column 2701;

[0055] During hoisting, the winding motor 16 drives the winding roller 17 to wind the lifting rope assembly 18, so that the fixed cylinder 20 drives the adjusting frame 24 to move upward, so that the adjusting frame 24 drives the sliding block 2501 above the folding frame 25 to move upward. Furthermore, the two sets of first folding rods 2503 and second folding rods 2504 below the sliding block 2501 drive the two sets of third folding rods 2505 below to rotate synchronously. The lower end of the third folding rod 2505 is bent, which can make the third folding rod 2505 cooperate with the use of the mounting shaft 2605 at the end of the sliding plate 2603, so as to drive the sliding plate 2603 to slide inside the frame plate 2601, so that the fixing plate 2706 below the vertical column 2701 clamps the precast component;

[0056] During clamping, the second double-action air pump 2712 above the sliding frame 2702 can be opened to make the second double-action air pump 2712 inflate the airbag 2708 inside the fixing plate 2706, so that the airbag 2708 drives the fixing rod 2710 to slide on the surface of the side plate 2707, which is convenient for the fixing rod 2710 to be squeezed and fixed according to the surface shape of the precast component, improving the fixing effect of the device;

[0057] When lifting precast components, the movable shaft 2704 can be rotated to adjust the angle of the use direction of the fixed plate 2706 at the end of the movable shaft 2704, and cooperate with the engagement between the clamping rod 3202 on the side limiting component 32 of the column 2701 and the clamping holes 2711 on the upper and lower sides of the limiting nut 2705, so as to facilitate the positioning of the fixed plate 2706 after angle adjustment. The clamping rod 3202 is elastically connected with the limiting frame 3201 through the third spring 3203, which is convenient for the use of the clamping rod 3202;

[0058] When it is necessary to turn during lifting to a certain height, the positioning component 28 on the surface of the limiting concave plate 12 can be opened, so that the cylinder 2801 drives the positioning block 2802 to extend, so that the positioning block 2802 arranged in a "Y" shape is stuck on the movable steel ball 1803 on the lifting rope assembly 18, which is convenient for the positioning of the movable steel ball 1803 on the lifting rope assembly 18 below the limiting concave plate 12. Then, by opening the first two-way air pump 2005 inside the fixed cylinder 20, the first two-way air pump 2005 inflates the inside of the sealing cylinder 2004 through the air charging pipe 2006, so that the movable plug 2009 inside the sealing cylinder 2004 slides upward on the inner steel wire rope 1802, and then it is convenient for the movable plug 2009 to drive the movable steel ball 1803 to move upward. Cooperating with the use of the movable steel ball 1803 fixed by the top positioning block 2802, the movable joint 1807 between the two groups of movable steel balls 1803 is engaged into the connecting rings 1804 at the upper and lower ends of the movable steel ball 1803, so that the lifting rope assembly 18 is hardened into a straight rod state, improving the stability of rotation and avoiding the phenomenon of swinging of the lifted precast component. After the lifting is completed, the first two-way air pump 2005 can draw the gas inside the sealing cylinder 2004 away through the air extraction pipe 2007, so that the movable plug 2009 moves downward, so that the movable plate 1805 inside the connecting ring 1804 at both ends of the movable steel ball 1803 is restored under the reset action of the first spring 1806, so that the lifting rope assembly 18 is in a toughened state for the use of the lifting rope assembly 18;

[0059] During lifting, the second reduction motor 3103 on the rotation adjustment component 31 at the bottom of the upper cylinder body 2001 of the fixed cylinder 20 can be opened, so that the second reduction motor 3103 drives the transmission gear 3102 to rotate through the connecting shaft 3101, so that the transmission gear 3102 drives the tooth block 30 on the surface of the connecting block 29 above the rotating disc 22 to engage and rotate, and then it is convenient for the rotating disc 22 to drive the adjusting frame 24 to rotate through the connecting rod 23, which is convenient for the rotation of the precast component after lifting. This is the use principle of the precast component lifting device.
