Abstract
The utility model relates to a novel self-locking oil cylinder, which is characterized by comprising a cylinder body (1) and a piston (3), wherein the piston (3) is arranged in the cylinder body (1); and springs (2) are arranged between the piston (3) and the cylinder body (1). The novel self-locking oil cylinder is simple in structure, convenient to use, easy and convenient to install and maintain and durable.
Description
Technical field
The utility model relates to a kind of self-locking oil cylinder, uses on the Normally closed type clamp holder of deep hole drill car especially for use in the colliery.
Background technique
At present, down-hole deep hole drill car clamp holder, at a pedestal two common operating cylinders to be installed, the oil cylinder pushing slips is held drilling rod tightly, but this clamp holder is when rig is stamped capable hole, when changing drilling rod, whole system is idle, is the active force that can't satisfy when not working in system drilling rod as a common clamp holder.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of novel self-locking oil cylinder is provided, and this self-locking oil cylinder can not only be realized the function of common oil cylinder, and can be in the situation that system realizes self-locking without fuel feeding.
The purpose of this utility model is achieved in that a kind of novel self-locking oil cylinder, and it comprises cylinder body and piston, and described piston is arranged in the cylinder body, and is provided with spring between described piston and the cylinder body.
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:
Piston 3.
Embodiment
Referring to Fig. 1, the utility model relates to a kind of novel self-locking oil cylinder, comprises cylinder body 1, spring 2 and piston 3, described cylinder body 1 is installed on the pedestal 6, described piston 3 is arranged in the cylinder body 1, and is provided with spring 2 between piston 3 and the cylinder body 1, and the oil circuit in the described cylinder body 1 is connected with piston 3.
Working principle:
If cylinder body 1 inside does not have pressure oil, 3 in piston can be outwards mobile under the effect of spring 2, can realize the self-locking of oil cylinder.
Claims (1)
1. a novel self-locking oil cylinder is characterized in that it comprises cylinder body (1) and piston (3), and described piston (3) is arranged in the cylinder body (1), and is provided with spring (2) between described piston (3) and the cylinder body (1).
