Description

Technical Field

[0001] The utility model belongs to the technical field of oil drill pipes, and particularly relates to a slip device for manually taking and placing and automatically clamping in oil drilling. Background Art

[0002] The drill pipe slips are placed between the drill pipe, casing or tubing and the kelly bushing, and are used to clamp and suspend the drill string in the well to prevent it from falling into the well. The slips themselves weigh about 60 kg, and 2-3 people are required to closely cooperate for lifting and lowering. The existing drill pipe slips are composed of three slip bodies connected by hinge pins. The left and right slip bodies are closed to clamp the drill pipe. The existing transfer, lifting and lowering device for drill tool slips can only move the drill tool slips. Since the lifting rods are inserted on both sides of the slips, it is impossible to automatically clamp and release the slips during the lifting and lowering of the slips on the trolley.

[0003] In summary, it is found in the actual application in the oil field that the device has the following disadvantages:

[0004] 1. During the manual extraction of the slips, 2 to 3 drillers are required to closely cooperate, resulting in low operation efficiency. The personnel are in direct contact with the slips, and the waist and hands are easily injured.

[0005] 2. The original transfer, lifting and lowering device for drill tool slips cannot achieve automatic clamping and release of the slips during the lifting and lowering of the slips with the trolley.

[0006] 3. When the original transfer, lifting and lowering device for drill tool slips is used on the drill pipe slips, it is necessary for people to manually insert the lifting rods into the slip handles, and manual operation cannot be eliminated.

[0007] 4. The handrail of the trolley of the original transfer, lifting and lowering device for drill tool slips is at the same height as the slips and is basically at a horizontal angle, with insufficient height. Personnel need to bend down to operate, which does not conform to human habits.

[0008] 5. The handrail of the original transfer, lifting and lowering device for drill tool slips adopts a single handrail design, which is not convenient for personnel to operate. Content of the Utility Model

A limiting groove 10-41 is opened on the upper pressing cover 10-4. The limiting groove 10-41 can limit the support frame 12; the width of the limiting groove 10-41 is smaller than the width of the activity groove 10-11. As Figure 4 shown in the figure, the adjustment roller 10-5 includes a circular plate 10-51 and a foot pedal 10-52; several foot pedals 10-52 are evenly installed between two circular plates 10-51. As Figure 5As shown, several anti-slip strips 10-521 are evenly installed on the front and back sides of several footrests 10-52. The footrests 10-52 can be stepped on to drive the screw rod to rotate. At the same time, the anti-slip strips 10-521 can prevent the footrests 10-52 from slipping and improve stability. For example, Figure 6 As shown, the support frame 12 includes two support rods 12-1 and a reinforcing rod 12-2. The reinforcing rod 12-2 is connected between the two support rods 12-1. The support rod 12-1 can connect the movable block 10-2 and the cross bar 8, and the reinforcing rod 12-2 can improve the strength between the two support rods 12-1.

The long arm 5, the handrail 6, the cross bar 8, and the mobile support adjustment mechanism form the cart. The long arm 5 forms a lever, and the lever principle is used to lift the slip body, which can be completed by one person. The movement of the slip body is realized through the cart. When the slip body moves, the fine adjustment of the position is realized through the adjustment mechanism, which is convenient for quickly adjusting the position of the slip body and enabling the slip body to quickly reach the designated position. When the cart is pressed down, it is assisted by the auxiliary footrest 9 to facilitate quick operation, and the counterweight box mechanism 7 on the cross bar 8 is used to achieve counterweight, enabling the operator to easily operate and reducing the labor intensity.
