Description

Technical Field

[0001] The invention relates to the technical field of hoisting devices, and more particularly to a prefabricated composite plate hoisting device which is convenient for fixing. Background Art

[0002] ‌Precast composite slab‌ is a type of floor that combines precast and cast-in-place components, consisting of a precast concrete base plate and a cast-in-place concrete laminate. This type of floor combines the high efficiency of precast concrete with the flexibility of on-site casting, which increases construction speed, reduces on-site work, and helps improve the overall quality of the building.

[0003] When hoisting and installing prefabricated composite panels, it is necessary to select hoists based on factors such as the size, weight, and operating radius of the composite panels. For the hoisting construction of smaller prefabricated components, four steel wire ropes can be used for point lifting; for larger composite panels, distribution beam hoists or rectangular frame distribution truss hoists can be used to ensure smooth lifting and uniform force on the composite panels. However, during hoisting, it is also necessary to control the horizontal angle of the slings to ensure that the horizontal angle of the slings should not be less than 60° and should not be less than 45°. Therefore, when hoisting prefabricated panels of different sizes, the angle installation position of the slings needs to be carefully adjusted, otherwise the prefabricated composite panels are prone to shaking or unstable center of gravity during the hoisting process. When placing the prefabricated composite panels, it is usually necessary for multiple installers to align and fix the prefabricated panels with the installation position under the prefabricated composite panels. There is a certain installation risk when the installers align manually. Summary of the invention

The sliding member 20 can be used to conveniently adjust and transpose the lifting lock hook 21, so that the composite plate workpieces 6 of different sizes can be quickly and stably fixed.

The auxiliary adjusting slider 8 can be adjusted and slid on the upper side of the auxiliary fixing plate 11, and the main fixing plate 10 can be adjusted and slid on the upper side of the main adjusting slider 15. The operator can fix the main adjusting slider 15 with bolts and adjust the position of the main adjusting slider 15, so as to adjust the appropriate lifting distance according to the size of the composite plate workpiece 6, so as to meet the requirements of stable lifting of composite plate workpieces 6 of different sizes; A number of magnetic parts 33 are equidistantly fixedly installed at the lower end of the positioning plate 5, through which the metal rods on the sides of the composite plate workpiece 6 can be adsorbed and fixed. The positioning plate 5 covers the top of the metal rods, which effectively prevents the two ends of the composite plate workpiece 6 from colliding with other objects during the lifting process, causing the metal rods to deform.

[0025] Working principle of the present invention: the installer sets the hoisting motor 1 at the top of the tower crane device, and the fixing hook 2 at the lower end of the hoisting motor 1 can adjust the height of the fixing hook 2 for easy hoisting. Four fixing parts 18 are set at the upper four corners of the stabilizing frame 12, and a hoisting steel cable 13 is set between the fixing part 18 and the fixing hook 2 bracket, wherein the hoisting angle between the hoisting steel cable 13 and the protective part 3 is 75°. The main fixing plate 10 on the upper side of the stabilizing plate 4 is "X"-shaped and set at the four corners of the stabilizing plate 4. The installer can adjust the distance of the hoisting point on the lower side of the main adjusting slider 15 by moving the installation position of the main adjusting slider 15. In the modern building scale, the length of the composite plate workpiece 6 is generally 2.8 to 6.0 m, and the width should not be greater than 2.4m, because its length and width can be set according to the actual scene of the building, it can be freely adjusted when using the device for hoisting, and the usage scene is more extensive. Since the distance between the stabilizing plate 4 and the composite plate workpiece 6 is short, the torque between the hoisting lock hook 21 is small. Therefore, after the composite plate workpiece 6 and the upper main adjustment slider 15 are fixedly connected, the installation safety angle range of the hoisting lock hook 21 is larger, making the stabilizing plate 4 and the composite plate workpiece 6 more stable, and improving the durability of the hoisting lock hook 21. When it is necessary to hoist a smaller composite plate workpiece 6, a four-point hoisting method can be adopted. The operator first slides the main adjustment slider 15 to a suitable position, and fixes the main adjustment slider 15 with bolts. After that, the lifting lock hooks 21 are fixedly installed at the lower ends of the four corner main adjustment sliders 15, and then the four lifting lock hooks 21 are connected with the lifting ring buckles pre-buried in the composite plate workpiece 6 to preliminarily fix the composite plate workpiece 6. When the lifting lock hooks 21 are stably connected to the composite plate workpiece 6, the operator can use a tool to rotate the support base 24. Since the support base 24 and the fixing rod 26 are threadedly connected, when the adjusting knob 25 is rotated, the adjusting knob 25 will synchronously drive the support base 24 downward, thereby increasing the total length between the support base 24 and the fixing rod 26, and finally the fixing rod 26 will contact the stabilizing plate 4. When the lifting lock hooks 21 and the fixing rod 26 are fixed and stable, the lifting lock hooks 21 are mainly responsible for the pulling force of the lifting process. The auxiliary fixing method of the fixing rod 26 can ensure that the stabilizing plate 4 is not prone to shaking during the hoisting process. Its main function is to ensure the stability of the composite plate workpiece 6. When the lifting lock hook 21 and the fixing rod 26 are fixed, the lifting lock hook 21 and the fixing rod 26 form a triangular stable structure, and the structure of the rotating rod 23 and the turning wire member 16 can make the lifting lock hook 21 taut and straight, so that the fixation of the composite plate workpiece 6 is more stable. At the same time, it can effectively share the strength of the lifting support to avoid the problem of excessive force on the lifting point and damage to the lifting point during hoisting. The contact plate 17 on the lower side of the support base 24 contacts with the composite plate workpiece 6. At this time, the stabilizing member 7 is connected to the composite plate workpiece 6 through the rotating rod 23. The side sliding member 20 will be lifted up, and the lifting lock hook 21 will be in a tightened state, so that the stabilizing plate 4 and the laminated plate workpiece 6 are in a stable state. The contact plate 17 is a hard rubber material component. The contact plate 17 reduces the surface damage of the laminated plate workpiece 6 during the contact process with the laminated plate workpiece 6, while increasing the friction of the contact surface, which can reduce the horizontal shaking of the laminated plate workpiece 6 during the lifting process and reduce the interference of the hoisting operator during the operation process. Finally, the operator places the positioning plate 5 at the metal rod positions at both ends of the laminated plate workpiece 6, and the positioning plate 5 covers the top of the metal rod, which effectively avoids the problem of deformation of the metal rod caused by the collision of the two ends of the laminated plate workpiece 6 with other objects during the lifting process. For a larger composite plate workpiece 6, a six-point lifting method can be used. The installer can adjust the auxiliary adjustment slider 8 and the main adjustment slider 15 to a suitable position, and then fix the auxiliary adjustment slider 8 with bolts, install a lifting hook 21 at the lower end of the auxiliary adjustment slider 8, and connect the lifting hook 21 at the lower end of the auxiliary adjustment slider 8 with the lifting ring of the composite plate workpiece 6. In the same way as the four-point lifting method, the composite plate workpiece 6 is fixed, and subsequent lifting operations can be performed; After the device hoists the composite plate workpiece 6 to the installation position and controls the crane to move the composite plate workpiece 6 to the approximate installation position, the operator can first determine the distance between the hoisting position and the installation position by the light emitted by the infrared positioning member 32 on the lower side of the positioning plate 5, and then use the tool to rotate the adjustment knob 25 to loosen the fixing rod 26 and the contact plate 17. At this time, after losing the limiting support of the fixing rod 26, the hoisting lock hook 21 is in a movable state. At this time, the operator can start the first electric rod 28 or the second electric rod 30 through the control handle 31 according to the needs of the site, wherein when the longitudinal adjustment member 27 contacts the composite plate workpiece 6, the longitudinal movement of the composite plate workpiece 6 can be controlled by the longitudinal adjustment member 27, and when the transverse adjustment member 29 contacts the composite plate workpiece 6, the transverse movement of the composite plate workpiece 6 can be controlled by the transverse adjustment member 29; During the use of the device, the minimum length of the structure composed of the fixing rod 26 and the supporting base 24 is greater than the minimum length of the first electric rod 28 and the second electric rod 30. During the installation and fixing process, the fixing rod 26 can play a certain role in limiting the first electric rod 28 when the composite plate workpiece 6 falls. The auxiliary sling 19 is an elastic structure and can undergo a certain degree of elastic stretching. Its function is to assist in stabilizing the two ends, and it does not participate in the overall lifting and fixing of the composite plate workpiece 6. When the light beam of the infrared positioning member 32 on the lower side of the positioning plate 5 is aligned with the four corners of the required installation position, it means that the composite plate workpiece 6 is completely aligned with the installation slot position. At this time, it is only necessary to control the overall descent to make the composite plate workpiece 6 clamped in the required installation position. There is no need to manually move the composite plate workpiece 6, which reduces the communication cost with the installation workers and the tower crane operators and improves the safety of the installation. At the same time, due to the structure of the positioning plate 5, the metal rods at both ends of the composite plate workpiece 6 can be adsorbed and fixed to effectively avoid collision and deformation of the metal rods during transportation. At the same time, the infrared positioning member 32 on the lower side of the positioning plate 5 can position the whole, making the installation more intuitive and improving the installation efficiency.
