Traction sliding hydraulic support system

Abstract

The invention relates to a traction sliding hydraulic support system which is formed by combining more than two traction sliding hydraulic supports. Each traction sliding hydraulic support comprises across beam, a top beam, a hydraulic jack, a hydraulic prop, a guide device and a support system. The cross beam is arranged at the front end of the top beam; one end of the guide device is fixed at the cross beam, the other end is connected in the top beam in a sliding manner; one end of the hydraulic jack is connected with the cross beam, the other end is connected with the top beam, the extension and the contraction of the hydraulic jack can drive the top beam to be near to or far from the cross beam within the range of the guide device; and the telescopic hydraulic prop and the support system are arranged on the bottom surface of the top beam. The cross beams of the adjacent supports form an integrated rigid beam through a connecting device, and the top beams of the adjacent supports are mutually connected by a sliding block. When the traction sliding hydraulic support system moves the supports, the adjacent supports are taken as support points for each other for respective movement, the support system simultaneously plays the support role for the supports, the support force is evenly distributed, the structure is compact and reasonable, and the safety and the reliability of the working environment of coal mining workers are improved.

Description

technical field [0001] The invention relates to a coal mine hydraulic support, in particular to a traction type sliding hydraulic support system. Background technique [0002] Coal mine support equipment is an important facility to ensure the safety of coal mine workers. The existing suspension or sliding hydraulic support is a support equipment that moves forward in a suspended state after the support is unloaded and lifted. The support that the support bears is perpendicular to The gravity of the top beam and the tension parallel to the top beam are transmitted to the adjacent brackets through the connection mechanism between the brackets, which makes the connection between the brackets bear a large force, especially for all brackets connected through the connection mechanism The combined sliding hydraulic support, the internal stress generated between the supports will be superimposed on the connecting mechanism, causing frequent damage to the connecting mechanism.
