Detailed Description

The present invention will be described with reference to specific embodiments.

Fig. 1 is a front view of the hook stabilizing device of the present invention, fig. 2 is a structural view of the hook stabilizing device of the present invention, and fig. 3 is a structural view of the first support rod, as shown in fig. 1 to 3.

Lifting hook stabilizing support device includes: hanger plate 1, backup pad 4 still include: a fixed plate 2 and a support structure 3. The fixed plate 2 is mounted on the hanger plate 1. The support structure 3 is mounted on the fixed plate 2. The support structure 3 comprises: a first support bar 31, a second support bar 32, and a third support bar 33.

The first support bar 31 includes: a first section 311 and a second section 312, wherein the first section 311 is a shaft with a fixed length. The second section 312 is a threaded shaft, and the second section 312 is connected with the support plate 4 through threads. As shown in fig. 3, the axial diameter of the first section 311 is greater than the axial diameter of the second section 312, and a positioning surface 313 is disposed at the connection between the first section 311 and the second section 312.

The first support rod 31, the second support rod 32 and the third support rod 33 have the same structure, and the first support rod 31, the second support rod 32 and the third support rod 33 are arranged in a triangular shape.

The lifting hook of the di sand shot blasting machine is frequently replaced, the main reason is that the positioning bolt of the supporting rod of the lifting hook is not flexible, so that the two ends are not balanced, the supporting rod and the chain wheel are abraded with higher speed, and the lifting hook is not stable in rotation. Therefore, the supporting rod 3 is transformed to be divided into a first section 311 and a second section 312, and the first section 311 is set to be of a fixed length, so that the complicated measuring and positioning process before the use is avoided. The second section 312 is provided as a threaded section for securing the support rod. By providing a difference in diameter between the first section 311 and the second section 312, the locating surface 313 is used for both direct locating and substantially avoids instability of bolted connections at both ends. However, threaded connections and bolted connections at the remaining end still have problems. Originally, only two bracing pieces, when one runs the position, another can't restrict, can receive its tired accelerated wear on the contrary. The event sets up three spinal branch vaulting poles, puts simultaneously and is triangle-shaped, compares in original structure firstly triangle-shaped itself and has stablized more and avoided shaking and has caused wearing and tearing, secondly can restrict the compensation each other between the three spinal branch vaulting poles, thereby reduces and runs the position volume and alleviate wearing and tearing. Specifically, the three support rods are fixed on the fixing plate 2 by welding.

The fixing plate 2 includes: first fixed column 21, second fixed column 22, third fixed column 23. The first fixing column 21, the second fixing column 22 and the third fixing column 23 are arranged in a triangular structure. The first fixing column 21, the second fixing column 22 and the third fixing column 23 are all cylinders, and a cylindrical groove is formed in the center of each cylinder. The first support rod 31, the second support rod 32 and the third support rod 33 are respectively installed in the first fixing column 21, the second fixing column 22 and the third fixing column 23.

The fixing plate 2 is arranged to further improve the stability of the support, and the first fixing column 21, the second fixing column 22 and the third fixing column 23 are arranged in a triangular shape to improve the placing reliability and are matched with the three support rods. The fixing plate 2 is provided to further restrict the positional relationship between the three support rods. The three fixing columns are respectively matched with the three supporting rods, so that the connection stability and rigidity of the supporting rods are further improved, the three supporting rods are limited from moving relative to the hanging plate, and the verticality of the three supporting rods relative to the hanging plate is guaranteed. Specifically, the fixing plate 2 is fixed to the hanger plate 1 by welding.

Lifting hook stabilizing support device still includes: a support plate 4. The supporting plate 4 is connected with the first supporting rod 31, the second supporting rod 32 and the third supporting rod 33 through threads. The bottom of the supporting plate 4 is provided with a first stabilizing plate 41, and the top is provided with a second stabilizing plate 42. The supporting plate 4, the first stabilizing plate 41 and the second stabilizing plate 42 are provided with screw holes at the centers thereof, which are communicated with each other.

The supporting plate 4 is used for fixing three supporting rods, and the first stabilizing plate 41 and the second stabilizing plate 42 are used for further improving the rigidity and the supporting stability of the supporting plate 4. The centrally located bolt hole is intended to be connected to a hanger bar 12 mounted on the hanger plate 1 for subsequent operation of the hook system.

Fig. 5 is a partial view B of fig. 1, as shown in fig. 5. A first nut 5 is connected to the second section 312, and the second section 312 is fixed in the support plate 4 by the first nut 5. The second nut 51 is arranged on the top of the first nut 5, and the second nut 51 is connected with the second section 312. The first nut 5 plays a role in fixing the support rod, and the second nut 51 is repeatedly fixed, so that the self-locking effect is achieved, and the stability of fixing is enhanced.

In use, the positioning surface 312 contacts the bottom surface of the supporting plate 4 to determine the positioning, and the supporting plate 4 is engaged with the first supporting rod 31, the second supporting rod 32, and the third supporting rod 33. The first nut 5 and the second nut 51 are tightened in this order.
