Detailed Description
The following detailed description of the present invention will be made in conjunction with the accompanying drawings and specific embodiments.
As shown in fig. 1, fig. 2, fig. 3, and fig. 4, the opposite-inserting type reducing bearing anti-falling pipe clamp includes: the slip comprises a three-wing slip body 1 and a two-wing slip body 2, wherein a first slip connecting sleeve 3 is arranged on one side of the three-wing slip body 1 far away from the two-wing slip body 2, a second slip connecting sleeve 4 is arranged on one side of the two-wing slip body 2 far away from the three-wing slip body 1, three first inserting blocks 5 are uniformly arranged on the other side of the three-wing slip body 1 close to the two-wing slip body 2, first inserting grooves 6 are respectively arranged between two adjacent first inserting blocks 5, first V-shaped clamping grooves 7 are arranged in the first inserting blocks 5, first clamping teeth 8 are respectively arranged on the first inserting blocks 5 in the first V-shaped clamping grooves 7, second inserting blocks 9 mutually matched with the first inserting grooves 6 are arranged on the other side of the two-wing slip body 2 close to the three-wing slip body 1, and second inserting grooves 10 mutually matched with the first inserting blocks 5 in the middle are arranged between the two second inserting blocks 9, be provided with second V type draw-in groove 11 in the second inserted block 9 be provided with second latch 12 on the second inserted block 9 in the second V type draw-in groove 11 respectively, first latch 8 is the same with second latch 12's structure, first latch 8 and second latch 12 adopt horizontal latch and vertical latch crisscross setting to be the meshing distribution structure respectively.
The working principle is as follows: before operation, a first slip connecting sleeve 3 on a three-wing slip body 1 and a second slip connecting sleeve 4 on a double-wing slip body 2 are connected with a slip connecting shaft respectively and then connected with a hydraulic system, an adjusting pipe column 13 is adjusted to be arranged between the three-wing slip body 1 and the double-wing slip body 2 during operation, the hydraulic system is opened, the slip connecting shaft pushes the three-wing slip body 1 and the double-wing slip body 2 to move towards the center simultaneously, and because a first V-shaped clamping groove 7 in a first inserting block 5 and a second V-shaped clamping groove 11 in a second inserting block 9 are in a V-shaped structure, the first inserting block 5 in the middle can be inserted into the second inserting groove 10, and the second inserting block 9 can be inserted into the first inserting groove 6 relatively, so that the pipe column 13 automatically moves towards the center without adjustment; when three wings slips body 1 and two wings slips body 2 continue to move to the center in step, until the first latch 8 in the first V type draw-in groove 7 and the second latch 12 in the second V type draw-in groove 11 tightly embrace tubular column 13, first latch 8 and second latch 12 adopt horizontal latch and vertical latch crisscross setting respectively to be latticed distribution structure latch and are latticed distribution, and the this moment is big with tubular column 13 contact point multiaspect, the atress is big more the fastening ability is stronger.
The use of the opposite insertion type reducing bearing anti-drop pipe clamping device is explained as follows:
(1) should carry out the equipment and the debugging at each connection position earlier before using to inserting formula reducing bears anti-falling pipe clamp, whether locking mechanism locks nimble direction, examines and then carries out the commissioning debugging after finishing.
(2) Before the opposite-insertion type reducing bearing anti-drop tube clamp is used, whether the opposite-clamping insertion-card tile is in the opposite-insertion slot or not is firstly adjusted, and no obstacle exists in the opposite-insertion process.
(3) Whether the check pipe column condition of blocking accords with to inserting the slips size before inserting formula reducing bearing anti-drop pipe clamp uses, it is good to do not skid the chucking when accomplishing the chucking in the card slot.
Maintenance precautions:
(1) carry out periodic inspection after using a period to inserting formula reducing and bear anti-falling pipe clamp, inspect each side condition, locking condition, wearing and tearing condition, the connection condition carries out the degree of depth inspection again, the change that will be timely to the serious part of wearing and tearing.
(2) The pipe clamping is stopped in time when abnormal phenomena or too large resistance occurs in the use process of the plug-in reducing bearing anti-drop pipe clamping device, and whether plug-in slips are in a plug-in state or whether foreign matters directly affect the effect of the plug-in slips or not is checked in time.
(3) And the disassembly and maintenance are carried out according to a standard process, and the latch of the slip is checked for a long time. The clamping teeth are worn greatly, the clamping teeth are required to be replaced in time so as not to influence clamping force, and the clamping teeth are required to be withdrawn from the original position in time after not being used, so that the service life and the strength of the slip are ensured.
