Abstract
The utility model relates to a normally closed holder, which is characterized by including a base (6) and oil cylinders mounted on the two sides of the base (6); each oil cylinder includes a cylinder body (1) mounted on the base (6) and a piston (3) arranged inside the cylinder body (1); springs (2) are arranged between each piston (3) and each cylinder body (1); and slips (5) are arranged at the end parts of the pistons (3). The normally closed holder not only has a simple structure and is convenient to use, but also is simple and convenient to mount and maintain, and is durable.
Description
Technical field
The utility model relates to a kind of normally closed type clamper, is mainly used under coal mine deep hole drill car and constructs with polish drill rod.
Background technology
At present, the down-hole deep hole drill car is constructed with polish drill rod, and pushing away needs clamper chucking drilling rod when pulling out drilling rod, and chuck also tightens drilling rod simultaneously, and unit head drives the chuck reverse rotation, breaks away between the drilling rod; The clamper that this function is general can be realized; But when drill carriage is vertically stamped capable hole, need clamper to embrace drilling rod when changing drilling rod, prevent the drilling rod landing, whole system is idle when changing drilling rod, so a kind of normally closed type clamper will be provided; Also there is a kind of normally closed clamper of realizing in existing market, but its complex structure, amateur manufacturing is difficult to reach desirable instructions for use, and the dismounting maintenance is difficulty all.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of normally closed type clamper is provided, and this normally closed type clamper can not only satisfy dismounting drilling rod in the work, prevent that up drilling rod from changing landing, and simple in structure, easy accessibility.
The purpose of this utility model is achieved in that a kind of normally closed type clamper, the oil cylinder that it comprises pedestal and is installed on the pedestal both sides, described oil cylinder comprises cylinder body and piston, described cylinder body is installed on the pedestal, described piston is arranged in the cylinder body, and be provided with spring between described piston and the cylinder body, be provided with slips in the end of described piston.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is not only simple in structure, and is easy to use, and installation, maintenance is easy, durable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein:
Cylinder body 1
Spring 2
Piston 3
Latch 4
Slips 5
Pedestal 6.
The specific embodiment
Referring to Fig. 1, the utility model relates to a kind of normally closed type clamper, mainly formed by pedestal 6 and the oil cylinder that is installed on pedestal 6 both sides, described oil cylinder comprises cylinder body 1, spring 2 and piston 3, and described cylinder body 1 is installed on the pedestal 6, and described piston 3 is arranged in the cylinder body 1, and be provided with spring 2 between piston 3 and the cylinder body 1, oil circuit in the described cylinder body 1 is connected with piston 3, is provided with slips 5 in the end of described piston 3, and described slips 5 links to each other with piston 3 by latch 4.
Operating principle:
If cylinder body 1 inside does not have pressure oil, 3 in piston can be outwards mobile under the effect of spring 2, and the end of piston 3 is connecting slips 5, and two group oil cylinder pistons 3 on the pedestal 6 are done the time spent simultaneously, can realize that slips 5 blocks drilling rod.
