Technical Field

[0001] This utility model belongs to the field of hoisting frame technology and relates to a profile hoisting frame. Background Technology

[0002] Currently, during the production and processing of profiles, when the profiles are moved to different workstations, a hoisting frame is generally used to hoist and transport them. Traditional profile hoisting mainly uses hooks to hook and transport the profiles. However, this method affects the stability of the profiles during the hoisting process. Therefore, we have designed a profile hoisting frame to solve the above-mentioned technical problems. Summary of the Invention

[0003] The purpose of this utility model is to provide a profile hoisting frame to solve the problems mentioned in the background art.

[0004] The purpose of this utility model can be achieved through the following technical solution: a profile hoisting frame, including a U-shaped bracket, a through hole is provided at the center of the U-shaped bracket, a sleeve is nested inside the through hole, a connecting bolt is inserted inside the sleeve, a metal spring is sleeved and connected to the bottom of the connecting bolt, and a locking nut is threaded at the connection between the connecting bolt and the sleeve.

[0005] In the aforementioned profile hoisting frame, the top of the connecting bolt is threaded with a lower nut and an upper nut, and two metal washers are nested between the lower nut and the upper nut and connected to the connecting bolt.

[0006] In the aforementioned profile hoisting frame, a conical cover is fitted onto the top of the sleeve, and the bottom of the conical cover contacts and connects with the top of the U-shaped bracket.

[0007] In the aforementioned profile hoisting frame, the bottom two sides of the U-shaped bracket are provided with barbed structures.

[0008] In the aforementioned profile hoisting frame, two symmetrically arranged rubber protective strips are fixed on both sides of the inner wall of the U-shaped bracket.

[0009] In the aforementioned profile hoisting frame, metal strips are fixed on both sides of the metal spring sheet, and the two metal strips are arranged symmetrically at the center.

[0010] Compared with the prior art, the advantages of the profile hoisting frame of this utility model are as follows: the hoisting frame can hook the bottom of the profile by means of the barb provided at the bottom of the U-shaped bracket and the metal spring provided at the top of the U-shaped bracket, and press the profile with the elasticity of the metal spring, thereby improving the stability of the profile hoisting.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-5 As shown, the present invention provides a profile hoisting frame, including a U-shaped bracket 1. A through hole 11 is provided at the center of the U-shaped bracket 1. A sleeve 2 is nested inside the through hole 11. A connecting bolt 9 is inserted inside the sleeve 2. A metal spring piece 3 is sleeved and connected to the bottom of the connecting bolt 9. A locking nut 7 is threadedly connected to the connection between the connecting bolt 9 and the sleeve 2.

[0019] Specifically, the hoisting frame uses the barb at the bottom of the U-shaped bracket 1 and the metal spring 3 at the top of the U-shaped bracket 1 to hook the bottom of the profile and press the profile with the elasticity of the metal spring 3, thereby improving the stability of the profile hoisting.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model discloses a profile hoisting frame, in which a lower nut 5 and an upper nut 8 are threadedly connected to the top of the connecting bolt 9, and two metal washers 6 are provided between the lower nut 5 and the upper nut 8 and nested with the connecting bolt 9.

[0021] Specifically, the lower nut 5 and the upper nut 8 facilitate the assembly of the connecting bolt 9 with the hoisting equipment.

[0022] A conical cap 4 is fitted onto the top of the sleeve 2, and the bottom of the conical cap 4 is in contact with the top of the U-shaped bracket 1.

[0023] The bottom of the U-shaped bracket 1 is equipped with barbed structures on both sides. Specifically, the barbed structures enable the profile to be hooked from the bottom.

[0024] Two symmetrically arranged rubber protective strips 10 are fixed on both sides of the inner wall of the U-shaped bracket 1.

[0025] Specifically, the rubber protective strip 10 enhances the protection of the profile by the U-shaped bracket 1.

[0026] Metal strips are fixed on both sides of the metal spring 3, and the two metal strips are arranged symmetrically at the center.

[0027] Specifically, the elasticity of the metal spring 3 is improved by using metal strips.

[0028] In practice, when using this profile hoisting frame, the profile is first placed inside the U-shaped bracket 1 by hand, and then the profile is pushed upward. At this time, the metal spring 3 deforms. When the bottom of the profile is hooked by the barb at the bottom of the U-shaped bracket 1, the hoisting is stopped. At this time, the profile is released by hand. When the metal spring 3 returns to its original position, it presses down on the profile, thereby ensuring the stability of the profile during the hoisting process.
