Description

Head hoist device

[ Field of technology ]

The invention relates to the field of chemical equipment machinery, in particular to an end socket hoisting device.

[ Background Art ]

In the prior art, lifting lugs are welded outside the sealing head when the sealing head is lifted, then the sealing head is lifted and installed with a cylinder body through lifting equipment, and 12Cr1MoV alloy steel and F91 round steel have larger hardening tendency and cold cracking tendency, and cold cracks and hot cracks can be generated during welding, so that the product quality is affected.

Therefore, it is necessary to provide a head hoisting device for solving the above technical problems.

[ Invention ]

In order to solve the problems, the invention aims to provide the sealing head lifting device which can reduce the surface cracks of products and improve the quality of the products.

In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: the utility model provides a head hoist device, includes the main pole frame, main pole frame both sides are connected with the arm lock that is used for clieing the head outer wall, the welding has the lug on the arm lock, still includes the lifting hook that is used for hooking the head inner wall, the lifting hook connect in main pole frame below.

The end socket hoisting device is further provided with: the two lifting lugs are respectively arranged at two ends of the clamping arm at one side of the main rod frame.

The end socket hoisting device is further provided with: and a rubber pad is arranged on the contact surface of the lifting hook and the inner wall of the end socket.

The end socket hoisting device is further provided with: the contact surface between the clamping arm and the outer wall of the seal head is formed by two inclined planes.

The end socket hoisting device is further provided with: the included angle formed between the two inclined planes is adjustable.

The end socket hoisting device is further provided with: and a rubber pad is arranged on the contact surface between the clamping arm and the outer wall of the seal head.

The end socket hoisting device is further provided with: the lifting hook is L-shaped.

Compared with the prior art, the invention has the following beneficial effects: the end socket lifting device is simple in structure and convenient to install, can reduce surface cracks of the end socket, improves product quality, and can be suitable for various specifications.

[ Detailed description ] of the invention

Example 1

Referring to fig. 1-3 of the specification, the invention discloses a sealing head lifting device, which comprises a main rod frame 1, wherein two sides of the main rod frame 1 are connected with clamping arms 2 for clamping the outer wall of a sealing head 5, lifting lugs 3 are welded on the clamping arms 2, and the sealing head lifting device further comprises a lifting hook 4 for hooking the inner wall of the sealing head, the lifting hook 4 is L-shaped, the lifting hook 4 is connected below the main rod frame 1, and the lifting hook 4 stretches into the inner hole wall of the sealing head 5 to hook the inner wall of the sealing head when lifting. The arrangement of the lifting hook 4 can ensure that the firmly lifted end socket cannot fall off.

In addition, the number of the lifting lugs 3 is at least two, and the lifting lugs are respectively arranged at two ends of the clamping arm 2 at one side of the main rod frame 1, so that stress points are transferred to the lifting device, and the quality problem of cracks generated when the lifting lugs are welded on the sealing head 5 is avoided. In addition, the lifting lug 3 is designed at two ends of the clamping arm at the same side, so that the sealing head can be conveniently turned over and lifted, and then the sealing head can be conveniently covered on new equipment.

The contact surface between the lifting hook 4 and the inner wall of the sealing head is provided with a rubber pad 41, so that the inner wall of the sealing head can be prevented from being scratched.

The contact surface between the clamping arm 2 and the outer wall of the seal head 5 is composed of two inclined planes 21, and the included angle formed between the two inclined planes 21 is adjustable. The arrangement of the two inclined planes can ensure that the two inclined planes are in contact with the sealing heads of different specifications, and the outer wall of the sealing head is round and can be better clamped through the angle adjustment between the two inclined planes, so that the stability during lifting is ensured.

The contact surface between the clamping arm 2 and the outer wall of the seal head 5 is provided with a rubber pad, so that the outer wall of the seal head can be prevented from being scratched.

The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, but any modifications, equivalent substitutions, improvements, etc. within the spirit and principles of the present invention should be included in the scope of the present invention.
