Integrated self-locking intelligent informationized hydraulic cylinder device

Abstract

The invention discloses an integrated self-locking intelligent informationized hydraulic cylinder device. The integrated self-locking intelligent informationized hydraulic cylinder device comprises an outer cylinder body and an inner cylinder body. An inward-contracting shoulder surrounds the opening of the inner cavity body, a columnar boss is arranged at the bottom of the outer cylinder body and stretches into the opening of the inner cylinder body, a peripheral outward-expanding shoulder is arranged at the end of the columnar boss, a first oil cavity is formed between the bottom of the outer cylinder body and the inward-contracting shoulder of the inner cylinder body, a second oil cavity is formed between the inner side of the bottom of the inner cylinder body and the end of the columnar boss, and an oil return cavity is formed between the outward-expanding shoulder of the outer cylinder body and the inward-contracting shoulder of the inner cylinder body. An oil cylinder clamping ring is connected with an oil cylinder skid shoe in a pressing mode and is connected to the outside of the bottom of the inner cylinder body through a bolt in a threaded mode. An oil return pipe connector is communicated with the oil return cavity through an oil return pipe, an oil inlet pipe connector is connected to a hydraulic lock through an oil inlet pipeline, the hydraulic lock is connected to the first oil cavity through an oil inlet pipeline, an oil pressure sensor is communicated with the first oil cavity, a displacement sensor is connected with a connecting rod through a bolt in a threaded mode, the connecting rod is connected with the oil cylinder clamping ring, and the first oil cavity is communicated with the second oil cavity through an oil pipe.

Description

technical field [0001] The invention relates to the construction field, in particular to an integrated self-locking intelligent information oil cylinder device. Background technique [0002] In the foundation pit construction of underground construction projects, steel supports are required to avoid the collapse of the pit wall when excavating the foundation pit. The existing steel support end joints are generally in the form of movable joints and steel wedges, which are first lifted by a crane when used. The special jack preloads the axial force on the steel support, and then inserts the steel wedge to transmit the force. When it is necessary to dismantle the steel support, first use a crane to hang the special jack on the active head at the end of the steel support, and then pressurize the special jack through the hydraulic oil pump, so that the foundation pit enclosure structure will produce a certain amount of outward movement. Displacement, after the steel wedge inser...

Problems solved by technology

However, in practical applications, this kind of steel support also exposes its insurmountable shortcomings: during the installation process of the support, the prestressing process requires the cooperation of a crane and two loading jacks, and there is no data collection record for the pressurization value. The value depends on the experience and responsibility control of the operator, and there are many construction techniques and a long time; in addition, during the demolition process, due to the long-term stress and deformation of the steel wedge, it is difficult to dismantle, or even impossible to dismantle. Due to the excavation and deformation of the foundation pit, the axial force attenuation of some supports will occur, and even the support will fail; although the measure of adding axial force twice can be adopted on the construction site, there are many difficulties in the construction of the second adding axial force on site. This problem cannot be solved essentially; moreover, the installation and removal of the steel support requires the cooperation of the crane and the operator, and the process is complicated and unsafe, so it has the disadvantage of consuming labor and time

[0004] However, there are still many defects and deficiencies in the existing devices. In view of this, those skilled in the art provide an integrated self-locking intelligent information oil cylinder device for the above problems.
