Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
As shown in fig. 1, the utility model provides a can stabilize holder of centre gripping, include: a base 10; the two clamping boxes 11 are oppositely arranged on the base 10, and a drill rod is arranged between the two clamping boxes 11; slips 12 are arranged on the side surface of each clamping box 11 corresponding to the drill rod; a pressing block 32 is arranged in the clamping box 11, and the pressing block 32 is fixedly connected with the slips 12;
one end of the pressing block 32, which is far away from the slip 12, extends outwards to form a balance block 35, a plurality of elastic pieces 36 are uniformly arranged on the side surface of the hydraulic cylinder 31, the elastic pieces 36 are positioned between the balance block 35 and the inner wall of the clamping box 11, and the elastic pieces 36 are belleville springs.
The working principle and the technical effect of the technical scheme are as follows:
the utility model provides a pair of holder that can stabilize centre gripping, slips 13 are equipped respectively to two centre gripping casees 11, with the drilling rod clamp between slips 13, elastic component 36 is at first with the compression of elastic component 36 in the installation, and elastic component 36 compresses 5mm in this embodiment, then through the elasticity of elastic component 36, provides thrust for compact heap 32, makes two slips 12 press from both sides the drilling rod tightly, makes the drilling rod clamp more stable.
In order to separate the slips and then take out the drill rod, a hydraulic cylinder 31 is arranged on the side surface of the inside of each clamping box 11 facing the slips 12, the telescopic rod of the hydraulic cylinder 31 is fixedly connected with a pressing block 32, and the hydraulic cylinder 31 is a single-acting oil cylinder.
In order to make the compact heap remove more steadily, preferred technical scheme does, two inside limiting plates 33 that all set up of centre gripping case 11, limiting plate 33 are located between pneumatic cylinder 31 and the slips 12, and the spacing hole 34 is all seted up corresponding pneumatic cylinder 31 position on every limiting plate 33, and compact heap 32 sets up in spacing hole 34.
In order to prevent the pressing block 32 from completely retracting into the clamping box 11, a preferable technical scheme is that a limiting groove 37 is formed in the side surface, corresponding to the hydraulic cylinder 31, of the pressing block 32, and when the hydraulic cylinder 31 is compressed, the limiting groove 37 sleeves a cylinder body of the hydraulic cylinder 31 inside the limiting groove.
