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

[0004] The purpose of the present invention is to provide a prefabricated composite panel hoisting device that is easy to fix, so as to solve the problems raised in the above background technology.

[0005] A prefabricated composite panel hoisting device that is easy to fix, comprising a hoisting motor, a fixing hook is fixedly installed at the lower end of the hoisting motor, a stabilizing plate is arranged at the lower side of the fixing hook, a stabilizing frame is fixedly installed around the stabilizing plate, protective pieces are fixedly installed at the four corners of the upper end of the stabilizing frame, four main fixing plates are fixedly installed at the diagonal positions on the upper side of the stabilizing plate, a main adjusting slider is slidably arranged in the middle of the main fixing plates, a hoisting lock hook is fixedly installed at the lower end of the main adjusting slider, a pair of auxiliary fixing plates are fixedly installed in the middle of the upper side of the stabilizing plate, an auxiliary adjusting slider is fixedly installed in the middle of the auxiliary fixing plates, and a main control is fixedly installed in the middle of the upper side end of the stabilizing plate;

[0006] One side of the middle part of the lower end of the stabilizing plate is fixedly installed with a first electric rod, and the other side of the middle part of the lower end of the stabilizing plate is fixedly installed with a second electric rod. The lower end of the first electric rod is fixedly installed with a longitudinal adjusting member, and the lower end of the second electric rod is fixedly installed with a transverse adjusting member. A pair of stabilizing members are arranged on both sides of the lower side of the stabilizing plate. A plurality of circular through grooves are equidistantly arranged on the upper side of the stabilizing member. A stabilizing rod is arranged inside the through groove of the stabilizing member. A pair of wire winding members are arranged on the side of the stabilizing member. Auxiliary suspension cables are fixedly installed on both sides of the lower end of the stabilizing plate, and positioning plates are fixedly installed at the lower ends of the auxiliary suspension cables.

[0007] Furthermore, fixing members are fixedly installed at the four corners of the upper side of the stabilizing frame, and a hoisting steel cable is fixedly installed between the hoisting motor and the fixing hook.

[0008] By adopting the above technical solution, the protective member can ensure that the hoisting angle between the hoisting steel cable and the stabilizing frame is within a suitable range, making the hoisting process more stable.

[0009] Furthermore, a sliding groove is arranged at the middle position of the stabilizing plate between the main fixing plate and the auxiliary fixing plate, and a control handle is fixedly installed at the lower end of the main control member.

A supporting base is rotatably arranged on the lower side of the adjusting knob. A cylindrical through groove is arranged in the middle of the upper end of the supporting base. A contact plate is fixedly installed at the lower end of the supporting base.

[0014] By adopting the above technical solution, the supporting base is threadedly connected to the fixing rod through the adjusting knob. When the adjusting knob rotates, it will synchronously drive the supporting base to move downward, thereby increasing the overall height of the fixing rod and the supporting base.

[0018] By adopting the above technical solution, the metal rod on the side of the laminated plate workpiece can be adsorbed and fixed by the magnetic attraction members, and the positioning plate covers the metal rod, effectively avoiding the problem that the two ends of the laminated plate workpiece collide with other objects during the lifting process, resulting in deformation of the metal rod.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0033] On one side of the middle part of the lower end of the stabilizing plate 4, a first electric rod 28 is fixedly installed. On the other side of the middle part of the lower end of the stabilizing plate 4, a second electric rod 30 is fixedly installed. At the lower end of the first electric rod 28, a longitudinal adjusting member 27 is fixedly installed. At the lower end of the second electric rod 30, a transverse adjusting member 29 is fixedly installed. On both sides of the lower side of the stabilizing plate 4, a pair of stabilizing members 7 are provided. On the upper side of the stabilizing member 7, a number of circular through grooves are equidistantly arranged. Inside the through grooves of the stabilizing member 7, a stabilizing rod is provided. On the side of the stabilizing member 7, a pair of wire winding members 16 are provided. At both sides of the lower end of the stabilizing plate 4, auxiliary suspension cables 19 are fixedly installed. At the lower end of the auxiliary suspension cable 19, a positioning plate 5 is fixedly installed. At the four corners of the lower end of the positioning plate 5, infrared positioning members 32 are fixedly installed;

[0034] At the four corners of the upper side of the stabilizing frame 12, fixing members 18 are fixedly installed. Between the hoisting motor 1 and the fixing hook 2, a hoisting steel cable 13 is fixedly installed. Through the protective member 3, it can be ensured that the hoisting angle between the hoisting steel cable 13 and the stabilizing frame 12 is within a suitable range, making the hoisting process more stable;

[0035] In the middle position of the stabilizing plate 4 between the main fixing plate 10 and the auxiliary fixing plate 11, a sliding groove 14 is provided. At the lower end of the main control member 9, a control handle 31 is fixedly installed. The main adjusting slider 15 can be slidably arranged within the range of the main fixing plate 10. The auxiliary adjusting slider 8 can be slidably arranged within the range of the auxiliary fixing plate 11;

[0036] The stabilizing member 7 and the wire winding member 16 are rotationally connected through a rotating rod 23. On the side of the wire winding member 16, a number of adjusting grooves 22 are equidistantly arranged. Inside the middle part of the hoisting locking hook 21, a sliding member 20 is slidably arranged. Through the sliding member 20, it is convenient to adjust and replace the position of the hoisting locking hook 21, so that different-sized laminated plate workpieces 6 can be quickly and stably fixed;

[0037] The stabilizing rod includes a fixing rod 26 arranged in the slot of the stabilizing member 7. On the lower side of the fixing rod 26, an adjusting knob 25 is threadedly arranged. On the lower side of the adjusting knob 25, a supporting base 24 is rotatably arranged. In the middle of the upper end of the supporting base 24, a cylindrical through groove is provided. At the lower end of the supporting base 24, a contact plate 17 is fixedly installed. The supporting base 24 is threadedly connected to the fixing rod 26 through the adjusting knob 25. When the adjusting knob 25 rotates, it will synchronously drive the supporting base 24 to move downward, thereby increasing the overall height of the fixing rod 26 and the supporting base 24. The contact plate 17 on its lower side can increase the contact area, facilitating the auxiliary fixation of the laminated plate workpiece 6;

[0038] A number of threaded grooves are equidistantly arranged at the upper ends of the main fixing plate 10 and the auxiliary fixing plate 11. 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 laminated plate workpiece 6, so as to meet the stable lifting of laminated plate workpieces 6 of different sizes;

[0039] A number of magnetic absorption parts 33 are fixedly installed at equal intervals at the lower end of the positioning plate 5. Through the magnetic absorption parts 33, the metal rods on the side of the laminated plate workpiece 6 can be adsorbed and fixed. The positioning plate 5 covers the metal rods, effectively avoiding the problem that the two ends of the laminated plate workpiece 6 collide with other objects during the lifting process, resulting in deformation of the metal rods.

[0040] Working principle of the present invention: The installer sets the hoisting motor 1 at the top of the tower crane device. The fixed hook 2 at the lower end of the hoisting motor 1 can adjust the height of the fixed hook 2 to facilitate hoisting. Four fixed parts 18 are fixedly arranged at the four corners of the upper end of the stabilizing frame 12. A hoisting steel cable 13 is arranged between the fixed part 18 and the bracket of the fixed hook 2. The hoisting angle between the hoisting steel cable 13 and the protective part 3 is 75°. The main fixing plates 10 on the upper side of the stabilizing plate 4 are arranged in an "X" shape at the four corners of the stabilizing plate 4. The installer can adjust the distance of the hoisting point under the main adjusting slider 15 by moving the installation position of the main adjusting slider 15. In the modern building scale, the size length of the laminated slab workpiece 6 is generally 2.8 - 6.0 m, and the width should not be greater than 2.4m. Since its length and width can be set according to the actual construction scenario, it can be freely adjusted during the hoisting of this device, and the application scenario is more extensive. Due to the short distance between the stabilizing plate 4 and the laminated plate workpiece 6, the torque between its hoisting hooks 21 is small. Therefore, after the laminated plate workpiece 6 is fixedly connected to the upper main adjustment slider 15, the installation safety angle range of its hoisting hooks 21 is larger, making the connection between the stabilizing plate 4 and the laminated plate workpiece 6 more stable, improving the durability of the hoisting hooks 21. When hoisting a laminated plate workpiece 6 with a smaller size, 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. Then, hoisting hooks 21 are fixedly installed at the lower ends of the four-corner main adjustment sliders 15. After that, the four hoisting hooks 21 are snap-connected to the hoisting rings pre-buried in the laminated plate workpiece 6 to preliminarily fix the laminated plate workpiece 6. When the connection between the hoisting hooks 21 and the laminated plate workpiece 6 is stable, the operator can use a tool to rotate the support base 24. Since the support base 24 is threadedly connected to the fixed rod 26, when rotating the adjustment knob 25, the adjustment knob 25 will synchronously drive the support base 24 downward, thereby increasing the total length between the support base 24 and the fixed rod 26. Eventually, the fixed rod 26 will contact the stabilizing plate 4. When the hoisting hooks 21 and the fixed rod 26 are fixedly stable, the hoisting hooks 21 mainly bear the pulling force during the hoisting process, ensuring that the device will not flip during the movement. The auxiliary fixing method of the fixed 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 laminated plate workpiece 6. When both the hoisting hooks 21 and the fixed rod 26 are fixed, the hoisting hooks 21 and the fixed rod 26 form a triangular stable structure. The structure of the rotating rod 23 and the wire-turning part 16 can make the hoisting hooks 21 stretched and tightened, making the fixation of the laminated plate workpiece 6 more stable. At the same time, it can effectively share the hoisting support force, avoiding the problem of excessive force on the hoisting point and damage to the hoisting point during hoisting. The contact plate 17 on the lower side of the support base 24 contacts the laminated plate workpiece 6. At this time, the stabilizer 7 will push up the side sliding part 20 through the rotating rod 23, and at the same time, the hoisting hooks 21 are 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 component made of hard rubber material. During the contact process with the laminated plate workpiece 6, the contact plate 17 reduces the surface damage of the laminated plate workpiece 6 while increasing the friction force of the contact surface, which can reduce the horizontal shaking of the laminated plate workpiece 6 during hoisting and reduce the interference during the operator's operation. Finally, the operator places the positioning plate 5 at the positions of the metal rods at both ends of the laminated plate workpiece 6. The positioning plate 5 covers the metal rods, effectively avoiding the problem that the two ends of the laminated plate workpiece 6 collide with other objects during hoisting, resulting in deformation of the metal rods.

[0041] For a relatively large laminated slab workpiece 6, a six-point lifting method can be adopted. The installer can adjust the auxiliary adjustment slider 8 and the main adjustment slider 15 to appropriate positions, 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 snap-connect the lifting hook 21 at the lower end of the auxiliary adjustment slider 8 with the lifting ring of the laminated slab workpiece 6. Similar to the four-point lifting method, fix the laminated slab workpiece 6, and then subsequent lifting operations can be carried out;

[0042] When the device hoists the laminated slab workpiece 6 to the installation position, after controlling the tower crane to move the laminated slab workpiece 6 to the approximate installation position, the operator can first judge the distance between the hoisting position and the installation position by the light emitted by the infrared positioning member 32 under the positioning plate 5, and then use a tool to rotate the adjustment knob 25 to loosen the fixed rod 26 and the contact plate 17. At this time, after losing the limit support of the fixed rod 26, the lifting hook 21 is in a movable state. At this time, according to the on-site requirements, the operator can start the first electric rod 28 or the second electric rod 30 through the control handle 31. When the longitudinal adjustment member 27 contacts the laminated slab workpiece 6, the longitudinal movement of the laminated slab workpiece 6 can be controlled through the longitudinal adjustment member 27. When the transverse adjustment member 29 contacts the laminated slab workpiece 6, the transverse movement of the laminated slab workpiece 6 can be controlled through the transverse adjustment member 29;

[0043] During the use of this device, the minimum length of the structure composed of the fixed rod 26 and the support base 24 is greater than the minimum length of the first electric rod 28 and the second electric rod 30. During the installation and fixation process, the fixed rod 26 can play a certain limit protection role for the first electric rod 28 when the laminated slab workpiece 6 falls;

[0044] The auxiliary sling 19 is an elastic structure and can be elastically stretched to a certain extent. Its function is to assist in stabilizing both ends and does not participate in the overall hoisting and fixation of the laminated slab workpiece 6. When the light column of the infrared positioning member 32 under the positioning plate 5 is aligned with the four corners of the position to be installed, it means that the laminated slab workpiece 6 is completely aligned with the installation groove. At this time, only by controlling the overall descent, the laminated slab workpiece 6 can be clamped in the position to be installed, without manually moving the laminated slab workpiece 6, reducing the communication cost between the installation workers and the tower crane operator, improving the installation safety. At the same time, due to the structure of the positioning plate 5, the metal rods at both ends of the laminated slab workpiece 6 can be adsorbed and fixed to effectively avoid the collision and deformation of the metal rods during the handling process. At the same time, the infrared positioning member 32 under the positioning plate 5 can position the whole, making the installation more intuitive and improving the installation efficiency.
