Description

Technical Field

[0001] The invention relates to the field of gas cylinder liner head welding, and in particular to an liner head flipping and hoisting device. Background Art

[0002] In the automated welding production process of the gas cylinder liner head, the traditional manual handling and flipping methods face many challenges due to the arc shape and heavy weight of the liner head. On the one hand, a single worker cannot independently complete the handling and positioning of the liner head, resulting in low production efficiency; on the other hand, when the liner head needs to be flipped between the upper and lower processes, manual operation is not only difficult, but also poses safety hazards. In addition, the frequent replacement of flipping and hoisting tools not only increases the labor intensity of workers, but also reduces production efficiency.

[0003] Chinese patent document CN221459623U discloses a pressure vessel head lifting clamp, which clamps heads of the same type but different sizes by shaking a handle, cooperating with a clamping group and a connecting plate, and rotates the clamping group in a rotating groove through a hydraulic cylinder and a rotating mechanism, so that the handle can clamp heads of different types and sizes. However, the device fails to solve the problem of flipping the inner liner head.

[0004] Therefore, it is necessary to design a device with both the inner liner head flipping and lifting functions to solve the above technical problems. Summary of the invention

[0005] In view of the deficiencies of the above-mentioned technology, the purpose of the present invention is to provide a liner head flipping and hoisting device to solve the problem that the liner head is difficult to flip in the prior art.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A flipping and lifting device for an inner liner head comprises a load-bearing mechanism and a clamping mechanism, and is characterized in that: the load-bearing mechanism comprises a lifting ear, a rotating support arm and an outer shaft, the lifting ear is fixedly connected to the middle part of the rotating support arm, and the outer shaft is fixedly connected to both ends of the rotating support arm; the clamping mechanism comprises an inner shaft, a radial positioning, a lateral positioning, a positioning lock, a fixing ring and a nylon block, the inner shaft is fixedly connected to both sides of the fixing ring, the inner shaft is rotatably connected to the outer shaft, the radial positioning is rotatably connected to the top of the fixing ring, the lateral positioning is rotatably connected to the bottom of the fixing ring, the positioning lock is fixedly connected to the outside of the fixing ring, and the nylon block is fixedly connected to the inside of the fixing ring.

[0008] Furthermore, the radial positioning includes a radial locator, a radial positioning clamp column, a radial positioning clamp, a radial positioning locking hook and a radial locator gasket. The radial locator is rotatably connected to the top of the fixing ring, the radial positioning clamp is slidably connected to the top of the fixing ring, the radial positioning clamp column is fixedly connected to the radial positioning clamp and is located on both sides of the radial locator, the radial positioning locking hook is fixedly connected to the radial positioning clamp, and the radial locator gasket is fixedly connected to the bottom of the radial locator.

The lateral locator is rotatably connected to the bottom of the fixed ring, the lateral locator nylon is fixedly connected to the lateral locator, the lateral positioning clamp is slidably connected to the bottom of the fixed ring, and the lateral positioning locking hook is fixedly connected to the lateral positioning clamp.

[0010] Furthermore, the radial locator gasket is made of stainless steel.

[0013] Beneficial effects:

[0014] 1. The present invention successfully realizes the integrated function of flipping and hoisting of the liner head.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0023] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between the two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1As shown, a liner head flip hoisting device includes a load-bearing mechanism 1 and a clamping mechanism 2. The load-bearing mechanism 1 includes a lifting lug 11, a rotating support arm 12 and an outer shaft 13, the lifting lug 11 is fixedly connected to the middle of the rotating support arm 12, and the outer shaft 13 is fixedly connected to both ends of the rotating support arm 12. The clamping mechanism 2 includes an inner shaft 21, a radial positioning 22, a lateral positioning 23, a positioning lock 24, a fixing ring 25 and a nylon block 26. The inner shaft 21 is fixedly connected to both sides of the fixing ring 25, and the inner shaft 21 is rotatably connected to the outer shaft 13 to realize the flipping action of clamping the inner liner head 3; the radial positioning 22 is rotatably connected to the top of the fixing ring 25, the lateral positioning 23 is rotatably connected to the bottom of the fixing ring 25, and the positioning lock 24 is fixedly connected to the outside of the fixing ring 25. After the positioning lock 24 is locked, the radial positioning 22 and the lateral positioning 23 cannot move, and the clamping mechanism 2 tightly clamps the inner liner head 3 to prevent the inner liner head 3 from falling off; the nylon block 26 is fixedly connected to the inside of the fixing ring 25 to protect the surface of the inner liner head 3 from damage.

[0025] like Figure 2 As shown, the radial positioning 22 includes a radial positioning device 221 , a radial positioning clamp column 222 , a radial positioning clamp 223 , a radial positioning locking hook 224 and a radial positioning device gasket 225 . The radial locator 221 is rotatably connected to the top of the fixing ring 25, the radial locating clamp 223 is slidably connected to the top of the fixing ring 25, the radial locating clamp column 222 is fixedly connected to the radial locating clamp 223 and is located on both sides of the radial locator 221. When the radial locating clamp 223 slides counterclockwise, the radial locating clamp column 222 drives the radial locator 221 to rotate counterclockwise until the radial locator 221 is perpendicular to the tangent of the fixing ring 25, and the radial positioning 22 enters a radial locking state, thereby achieving radial fixation of the inner liner head 3, so that the inner liner head 3 cannot fall off the clamping mechanism 2; conversely, when the radial locating clamp 223 slides clockwise, the radial locator 221 is gradually retracted, and the radial positioning 22 exits the radial locking state, at which time the inner liner head 3 can be taken out of the clamping mechanism 2. The radial positioning lock hook 224 is fixedly connected to the radial positioning clamp 223. When the radial positioning 22 is in the radial locking state, the radial positioning lock hook 224 can use the positioning lock 24 to lock the radial positioner 221, so that the radial positioning 22 remains in the radial locking state. The radial positioner gasket 225 is fixedly connected to the bottom of the radial positioner 221 and contacts the surface of the liner head 3. The radial positioner gasket 225 is made of stainless steel to solve the problem that the contact surface of the liner head 3 is easily rusted when using iron materials and it is difficult to fix it under the radial positioner 221 when using plastic materials.

[0026] like Figure 3As shown, the transverse positioning 23 includes a transverse positioning device 231, a transverse positioning device nylon 232, a transverse positioning locking hook 233 and a transverse positioning clamp 234. The transverse positioning device 231 is rotatably connected to the fixing ring 25, and the transverse positioning device nylon 232 is fixedly connected to the transverse positioning device 231. When the transverse positioning device 23 is in a locked state, the transverse positioning device nylon 232 is in close contact with the liner end cap 3, and the transverse positioning device nylon 232 increases the friction between the transverse positioning device 231 and the liner end cap 3, so that the liner end cap 3 cannot be rotated horizontally left and right, and the liner end cap 3 will not slide when flipped.

[0027] like Figure 4 As shown, the transverse positioning clamp 234 is slidably connected to the fixing ring 25, and the transverse positioning lock hook 233 is fixedly connected to the transverse positioning clamp 234. The two ends of the transverse positioning clamp 234 are designed to transition from a cylinder to a flat. When the transverse positioning clamp 234 slides clockwise, the cylindrical part of the transverse positioning clamp 234 is located below the transverse positioner 231, so that the transverse positioner 231 tilts toward the inside of the fixing ring 25, so that the transverse positioner nylon 232 is in close contact with the liner head 3, so that the transverse positioning 23 enters a transverse locking state; on the contrary, when the transverse positioning clamp 234 slides counterclockwise, the flat part of the transverse positioning clamp 234 is located below the transverse positioner 231, so that the transverse positioner 231 is loosened, so that the transverse positioner nylon 232 is separated from the liner head 3, and the transverse positioning 23 exits the transverse locking state. When the lateral positioning device 23 enters the lateral locking state, the lateral positioning locking hook 233 can use the positioning lock 24 to lock the lateral positioning device 231 so that the lateral positioning device 23 remains in the lateral locking state.
