Description

Technical Field

[0001] This utility model relates to the technical field of hoisting devices for prefabricated slabs in prefabricated buildings, specifically a stabilizing mechanism and a hoisting device for prefabricated slabs in prefabricated buildings. Background Technology

[0002] Lifting refers to the general term for the installation and positioning of equipment using cranes or hoisting mechanisms. Conventional lifting mechanisms work by connecting the four ends of the workpiece to steel cables, which in turn connect to hooks on the crane, thus lifting the workpiece.

[0003] However, steel ropes are often only hung on both sides of the hook. During the hoisting process, they are affected by wind and machine vibration, causing the steel ropes to sway back and forth on the hook. This causes the locking mechanism on the steel ropes to gradually loosen, affecting the stability when hoisting precast slabs and thus posing a safety hazard. Therefore, this utility model proposes a stabilizing mechanism and a hoisting device for precast slabs of prefabricated buildings to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a stabilizing mechanism and a hoisting device for prefabricated building slabs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stabilizing mechanism, the stabilizing mechanism comprising:

[0006] The hook main body assembly includes a screw, a hook, a lower clamping block protrusion, a guide rod seat, and a lifting ring, wherein the hook is fixedly connected to the lower end of the screw and the lifting ring is fixedly connected to the upper end of the screw;

[0007] An adjusting assembly is screwed onto a screw rod. The adjusting assembly includes an adjusting nut and an adjusting fixing member. The adjusting fixing member is fixedly connected below the adjusting nut, and a pin fixing hole is formed on the lower side of the adjusting fixing member around its circumference.

[0008] A clamping assembly is slidably connected to a screw and located between an adjusting assembly and a hook. The clamping assembly includes a clamping assembly slide tube, a clamping block, an upper clamping block protrusion, a pin assembly, and a guide rod.

[0009] Preferably, the upper end of the sliding tube of the clamping assembly is provided with a slot, and a rotatable connecting block is rotatably connected inside the slot, the block being fixedly connected to the lower end of the adjusting fastener.

[0010] Preferably, a set of clamping blocks are symmetrically arranged on both sides of the clamping assembly slide tube, and the outer side of the clamping block is fitted to the inner side of the hook.

[0011] Preferably, a set of lower clamping block protrusions are symmetrically arranged on the upper side of the hook, and a set of upper clamping block protrusions are symmetrically arranged on the lower side of the clamping block, wherein the upper clamping block protrusions and the lower clamping block protrusions are staggered.

[0012] Preferably, a set of guide rods is provided on both sides of the clamping assembly, and a set of guide rod seats is provided on both sides of the hook, wherein the guide rod seats correspond to the positions of the guide rods, and the inner side of the guide rod seats matches the outer side of the guide rods.

[0013] Preferably, a set of pin support seats are symmetrically arranged on both sides of the clamping assembly. A pin assembly is fixed on the pin support seats.

[0028] Please see Figure 1-6 The present invention provides the following two preferred embodiments:

[0029] Example 1

[0030] A stabilizing mechanism includes: a hook body assembly 1, an adjusting assembly 2, and a clamping assembly 3. The hook body assembly 1 includes a screw 4, a hook 5, a lower clamping block protrusion 6, a guide rod seat 7, and a lifting ring 12, wherein the hook 5 is fixedly connected to the lower end of the screw 4, and the lifting ring 12 is fixedly connected to the upper end of the screw 4; the adjusting assembly 2 is screwed onto the screw 4, and includes an adjusting nut 14 and an adjusting fixing member 15, wherein the adjusting fixing member 15 is fixedly connected below the adjusting nut 14, and the lower side of the adjusting fixing member 15 has a pin fixing hole 16 on its circumference; the clamping assembly 3 is slidably connected to the screw 4 and is disposed between the adjusting assembly 2 and the hook 5. The clamping assembly 3 includes a clamping assembly slide tube 8, a clamping block 9, an upper clamping block protrusion 10, a pin assembly 11, and a guide rod 13. By setting up a stabilizing mechanism consisting of the hook main assembly 1, the adjusting assembly 2, and the clamping assembly 3, the position of the clamping assembly 3 on the screw 4 is adjusted by rotating the adjusting nut, thereby adjusting the distance between the lower side of the clamping block 9 and the upper side of the hook 5. Furthermore, by setting the upper clamping block protrusion 10 on the lower side of the clamping block 9 and the lower clamping block protrusion 6 on the upper side of the hook 5, the friction between the upper side of the hook 6 and the lower side of the clamping block 9 is increased, thereby clamping the steel ropes hanging on both sides of the hook 5 through the clamping assembly 3, thus improving the stability during hoisting.

[0031] The upper end of the clamping assembly slide tube 8 is provided with a slot 23, and a locking block 22 is rotatably connected inside the slot 23. The locking block 22 is fixedly connected to the lower end of the adjusting fastener 15.

[0032] A set of clamping blocks 9 are symmetrically arranged on both sides of the clamping assembly slide tube 8, and the outer side of the clamping block 9 is fitted with the inner side of the hook 5.

[0033] A set of guide rods 13 is provided on both sides of the clamping assembly 3, and a set of guide rod seats 7 is provided on both sides of the hook 5. The guide rod seats 7 are positioned corresponding to the guide rods 13, and the inner side of the guide rod seats 7 matches the outer side of the guide rods 13.

[0034] Example 2

[0035] Based on Embodiment 1, a set of pin assemblies 11 are symmetrically arranged on both sides of the clamping assembly 3. The pin assemblies 11 limit the rotation of the adjusting nut 14, thereby locking the adjusting assembly 2 and preventing the adjusting assembly 2 from loosening.

[0036] Working principle: In actual use, pull out the pin 20, rotate the adjusting nut 14, and the clamping assembly 3 will slide upward on the screw 4 through the adjusting fixing part 15, so that the clamping block 9 moves out of the inner side of the hook 5. Hang the steel rope on both sides of the hook 5, and then rotate the adjusting nut 14 to make the clamping assembly 3 move downward, thereby clamping the steel rope through the clamping block 9. When it moves to the bottom, release the pin 20, so that the return spring 19 drives the pin 20 to insert into the corresponding pin fixing hole 16, thereby locking the adjusting assembly 2, thereby locking the position of the steel rope in the hook 5, thereby improving the stability of the hoisting device.
