It has the characteristics of light weight, high strength, and corrosion resistance. Compared with traditional bricks, reinforced concrete and other materials, precast concrete panels have the advantages of light weight, fast construction speed, stable quality, fire resistance, and sound insulation. Precast concrete panel hoists are a commonly used hoisting tool in construction, which are specifically used to hoist precast concrete panels to designated locations to play a supporting and fixing role.

[0003] The patent with application number 202022542669.7 discloses a lifting device for precast concrete composite panels. The lifting device for precast concrete composite panels, through the setting of steel wire rope, upper pulley, lower pulley and adjusting rope, the upper pulley and the lower pulley make the force of the steel wire rope and the adjusting rope more balanced, the structure is simple and clear, and the lifting is safe and stable; in combination with the above application, and in connection with the existing lifting structure, when the existing lifting device is used to lift the precast concrete panels, due to the different sizes of different types of precast concrete panels, the fixed structure of the lifting device cannot be suitable for different types of precast concrete panels, which affects the stability during lifting and reduces the practicability of the device. For this reason, we propose a lifting device for precast concrete composite panels. Utility Model Content

[0004] The purpose of the utility model is to provide a lifting device for building concrete precast composite panels to solve the problem raised in the above-mentioned background technology that when using existing lifting devices to lift concrete precast panels, due to the different sizes of different types of concrete precast panels, the fixed structure of the lifting device cannot be adapted to different types of concrete precast panels, which affects the stability during lifting and reduces the practicability of the device.

[0010] Preferably, the buffer limiting plate is penetrated and limited by the buffer limiting rod, and a buffer spring is installed on the buffer limiting rod at the bottom of the buffer limiting plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) By setting the adjustable lifting device structure, when the device is used to lift concrete precast panels, if the lengths of the precast composite panels to be lifted are different, the installed transverse synchronous motor and the transverse lifting rod can be used for adjustment.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] See also Figure 1 and Figure 2The utility model provides a technical solution: the hoist is usually divided into two types: single-point hoisting and multi-point hoisting. In the single-point hoisting type, only one hanging point is needed to complete the hoisting operation, which is suitable for occasions where the hoisting points are relatively concentrated, such as beams and walls, while the multi-point hoisting type can adjust the hoisting position to balance the center of gravity by setting multiple hoisting structures. A building concrete prefabricated composite plate hoist includes a hoisting frame 100, a reinforcing beam 101 is welded and fixed on the inner side of the hoisting frame 100, and the hoisting frame 100 An I-beam 103 is welded and fixed at both ends of the lifting frame 100, a lifting rope 102 is connected to the bottom of the lifting frame 100, a lifting hook 104 is installed at the bottom of the lifting rope 102, a transverse synchronous motor 205 is fixedly installed at one end of the I-beam 103, one end of the transverse synchronous motor 205 is located between the I-beam 103 and the reinforcing crossbeam 101, and a transverse threaded rod 204 is installed at both ends of the transverse threaded rod 204. A transverse lifting rod 200 is also installed on the inner side of the lifting frame 100. Both ends of the mounting rod 200 are provided with lifting sliders 201, and the inner side of the lifting frame 100 is provided with a lifting slide groove 202. When the multi-point lifting sling in the application is used to lift the concrete prefabricated composite board, the sling can be adjusted according to the length of the composite board before lifting. During the adjustment, the transverse synchronous motor 205 rotates and drives the transverse threaded rod 204 installed on the inner side of the lifting frame 100 to rotate. When the transverse threaded rod 204 rotates, it drives the transverse lifting rod 200 to move horizontally through the threaded hole 207. Two transverse lifting rods 200 are symmetrically arranged at both ends of the inner side of the lifting frame 100. When the transverse lifting rod 200 moves laterally, it is kept horizontal by sliding the lifting slider 201 and the lifting slide groove 202. At the same time, it is strengthened by the penetrating limiting guide rod 203 to improve the overall structural strength and avoid deformation and damage of the structure during the lifting process. The symmetrical transverse lifting rod 200 can be used for lifting plates of different lengths after transverse adjustment, which can be better used for lifting. At the same time, it improves the stability during lifting and is convenient to use.

[0021] Specifically, a threaded hole 207 is provided on the inner side of the transverse lifting rod 200, and limit holes 206 are provided at both ends of the threaded hole 207. The transverse threaded rod 204 is installed through the threaded hole 207 and can be driven to move by the thread when rotating. The limit guide rod 203 passes through the limit hole 206, which ensures the stable displacement of the transverse lifting rod 200 while enhancing the structural stability. The two ends of the transverse lifting rod 200 and the lifting frame 100 are limited by the lifting slide groove 202 and the lifting slider 201 to ensure the stability during the transverse movement. Two transverse synchronous motors 205 are symmetrically installed on the I-beams 103 at both ends of the lifting frame 100, and the two transverse lifting rods 200 are symmetrically adjusted by the two transverse synchronous motors 205 to better drive the two installed transverse lifting rods 200 to move synchronously, ensuring symmetry and stability during the lifting process.

[0022] Example 2

[0023] See also Figure 1 and Figure 3 The utility model provides a technical solution: a construction concrete prefabricated composite slab sling, the installation of the sling 102 is transverse to the bottom of the sling rod 200, and the sling buffer 300 is also installed on the sling 102, the inner side of the sling buffer 300 is provided with a buffer cavity 301, the inner side of the buffer cavity 301 is provided with a buffer limit plate 303, and the inner edge of the buffer cavity 301 is provided with a buffer limit rod 302. During the lifting process, if the sling 102 is lifted too fast, the sling 102 may be broken. By setting the sling buffer 300 on the sling 102, during the lifting and pulling process, the bottom sling 102 is connected to the buffer limit plate 303 inside the sling buffer 300. When the lifting ropes 102 at both ends are pulled by force, the buffer limit plate 303 moves to one side through the buffer limit rod 302, and at the same time, the buffer spring 304 is squeezed and deformed during the movement. The deformation of the buffer spring 304 produces a certain buffering force, thereby reducing the force on the lifting rope 102 during the lifting and pulling process, avoiding the breakage of the lifting rope 102, thereby improving the stability and safety of the device during the lifting process. Specifically, the buffer limit plate 303 is limited by the buffer limit rod 302, and a buffer spring 304 is installed on the buffer limit rod 302 at the bottom of the buffer limit plate 303. During the buffering process, the buffer spring 304 on the buffer limit rod 302 is squeezed to provide a buffering force.
