[ Detailed description ] of the invention
Example 1
Referring to fig. 1-3 of the specification, the invention discloses a telescopic sealing head lifting device, which comprises a main rod frame 1 and two clamping arms 2 used for clamping the outer wall of a sealing head 5, wherein the two clamping arms 2 are respectively connected with two ends of the main rod frame 1, the length of each clamping arm 2 is adjustable through arranging a telescopic sliding block device, the contact surface between each clamping arm 2 and the outer wall of the sealing head 5 is composed of two inclined planes 21, the angle between the two inclined planes 21 is adjustable, the sealing heads with various specifications can be adapted through adjusting the length of each clamping arm and the angle between the inclined planes, the lifting device is not required to be matched independently, the operation is convenient, and the cost is reduced. The arrangement of the two inclined planes can ensure that the two inclined planes are in contact with the sealing heads with 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.
The device is still including being used for hooking the lifting hook 4 of head inner wall, lifting hook 4 be the L type, lifting hook 4 connect in main pole frame 1 below, lifting hook 4 stretch into the hole wall of head 5 when lifting by crane, and the inner wall of head is hooked to the lifting hook 4, the contact surface of head inner wall is equipped with rubber pad 41, and the setting of lifting hook 4 can guarantee firm lifting head and be unlikely to drop, and is further, the contact surface of lifting hook 4 and head 5 inner wall is equipped with non slipping spur 41, the bottom of non slipping spur 41 and the up end butt of lifting hook 4 to through bolt and lifting hook 4 fixed connection, can further guarantee the stability of lifting by crane the process.
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 lifting lugs 3 are welded on the clamping arms 2, the number of the lifting lugs 3 is at least two, the lifting lugs 3 are respectively arranged at two ends of the clamping arms 2 at one side of the main rod frame 1, stress points are transferred to the lifting device, so that the quality problem of cracks generated when the lifting lugs are welded on the sealing head 5 is avoided, and in addition, the lifting lugs 3 are designed at two ends of the clamping arms at the same side, so that the sealing head can be conveniently turned over and lifted, and then can be conveniently covered on new equipment.
