Description

Rotatable head hoist device

[ technical field ] A method for producing a semiconductor device

The utility model relates to a chemical industry equipment machinery, concretely relates to rotatable head hoist device.

[ background of the invention ]

In the prior art, lifting lugs are welded outside the end socket during lifting, then the end socket is lifted by a lifting device and mounted with a cylinder body, 12Cr1MoV alloy steel and F91 round steel have large quenching tendency and cold cracking tendency, and cold cracks and hot cracks can be generated during welding, so that the product quality is influenced. In addition, the end socket hoisting device in the prior art is single in applicable specification and incapable of adjusting the size, different hoisting devices are required to be adopted according to end sockets of different specifications, time and labor are wasted, and the operation is complex.

Therefore, it is necessary to provide a rotatable head lifting device to solve the above technical problems.

[ Utility model ] content

In order to solve the problem, the utility model aims to provide a can adapt to multiple specification head and can improve product quality's rotatable head hoist device.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the clamping device comprises a main rod frame and two clamping arms used for clamping the outer wall of a seal head, wherein the two clamping arms are respectively connected with the two ends of the main rod frame through rotating hinges, the included angle between each clamping arm and the main rod frame is adjustable within the range of 45-180 degrees, the clamping arms are welded with at least two lifting lugs, and the two lifting lugs are respectively arranged at the two ends of the clamping arm on one side of the main rod frame.

The utility model provides a rotatable head hoist device further sets up to: still including being used for hooking the lifting hook of head inner wall, the lifting hook connect in main beam frame below. The lifting hook is L-shaped.

The utility model provides a rotatable head hoist device further sets up to: and a rubber pad is arranged on the contact surface of the lifting hook and the inner wall of the end socket.

The utility model provides a rotatable head hoist device further sets up to: the contact surface of the clamping arm and the outer wall of the end socket consists of two inclined planes.

The utility model provides a rotatable head hoist device further sets up to: the included angle formed between the two inclined planes is adjustable.

The utility model provides a rotatable head hoist device further sets up to: and a rubber pad is arranged on the contact surface of the clamping arm and the outer wall of the end socket.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model provides a rotatable head hangs the head that can be suitable for multiple specification through the contained angle of adjusting arm lock and mobile jib frame, strong adaptability, device simple structure, simple to operate, also can reduce head surface crack in addition, improve product quality.

Fig. 1 is the utility model discloses rotatable head hoist device's among the embodiment 1 structural schematic diagram.

Fig. 2 is a schematic sectional view of the embodiment 1 of the present invention, shown in fig. 1B-B.

Fig. 3 is a schematic structural diagram of an application state of embodiment 1 of the present invention.

In fig. 1 to 3: 1. the device comprises a main rod frame, 2, clamping arms, 21, an inclined plane, 3, lifting lugs, 4, lifting hooks, 41, a rubber pad, 5 and a seal head.

[ detailed description ] embodiments

Example 1

Please refer to the attached drawings 1-3 of the specification, the utility model relates to a rotatable head hoist device, including king-rod frame 1 and two arm lock 2 that are used for cliping 5 outer walls of head, two arm lock 2 pass through rotatory hinged joint with king-rod frame 1 both ends respectively, the contained angle between arm lock 2 and the king-rod frame 1 is adjustable at 45 ~ 180 within ranges, can adapt to the head of multiple specification size through adjusting this contained angle, need not match hoist device alone again, and convenient operation reduces the cost.

The welding has lug 3 on arm lock 2, lug 3 is two at least, install respectively in 1 one side arm lock 2's of main lever rack both ends, on the stress point just so shifted hoisting device, produced the quality problem of crackle when just having avoided welding the lug on head 5 like this, lug 3 designs at the arm lock both ends with one side in addition, can conveniently lift the head upset and be convenient for cover on new equipment after.

This device is still including being used for hooking the lifting hook 4 of head inner wall, lifting hook 4 is the L type, lifting hook 4 connect in 1 below of main beam frame, lifting hook 4 stretch into the interior pore wall of head 5 when lifting by crane, hook the inner wall of head, lifting hook 4 is equipped with rubber pad 41 with the contact surface of head inner wall, and lifting hook 4's setting can guarantee that firm the head of hoisting is unlikely to drop.

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

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

The above embodiments are merely preferred embodiments of the present disclosure, which are not intended to limit the present disclosure, and any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present disclosure, should be included in the scope of the present disclosure.
