The hydraulic support is an important component of fully-mechanized mining equipment, and can reliably and effectively support and control the top plate of the working face, isolate the stepping area and prevent gangue from entering the stope face, the propelling conveyor and the like.
In the fully-mechanized coal mining process, the stability of the end face top coal is maintained in a timely supporting mode, and a side protection plate and a telescopic front cantilever are arranged on a top coal hydraulic support.
The hydraulic support moving and straightening mode in the prior art is that a worker locates the hydraulic supports at two ends of a working face firstly, pulls wires after locating the positions, pulls the wires from the head to the tail and tightens the wires for fixation, then installs the hydraulic support, and after the hydraulic support is installed, the hydraulic support is verified in an auxiliary mode by using an infrared laser direction indicator, so that the hydraulic support is ensured to be in a straightening state, and the hydraulic support is adjusted and moved in the subsequent moving process through naked eye observation of the worker.
Disclosure of Invention
The utility model aims to provide an auxiliary device for straightening a hydraulic support, which aims to solve the problem that a worker in the background art observes a straightening hydraulic support by naked eyes to cause a large straightening error.
In order to achieve the above purpose, the basic scheme provided by the utility model is as follows: the novel sliding sleeve comprises an L-shaped supporting rod and an arc-shaped rod, wherein a sleeve is sleeved on the L-shaped supporting rod in a sliding mode, the arc-shaped rod is fixedly connected to the sleeve, and a limiting assembly used for limiting the sleeve to slide is connected to the sleeve.
The principle and the beneficial effects of the utility model are as follows: in the fully-mechanized coal mining process, along with continuous cutting of coal walls by a machine, corresponding movement of the hydraulic supports is required, and when the hydraulic supports move, the specific operation mode is that a worker firstly measures the distance of the hydraulic supports at two ends of a working face, which is required to move, by using a tape measure, and then pulls wires from the head to the tail and tightens the wires to be fixed after determining the moving distance and the final position, then the worker installs the L-shaped support rod on the hydraulic supports, slides the sleeve until the pulled wires are stopped when being positioned in the arc rods, fixes the sleeve by using the limiting assembly, sequentially removes the positions of other sleeves and moves the hydraulic supports by using the fixed sleeve as a reference until the pulled wires are positioned in each adjusted arc rod, and therefore the purpose of straightening the hydraulic supports is achieved. Compared with the prior art, the auxiliary device for the hydraulic support row is used for moving and arranging the hydraulic support through the movable sleeve, so that the problem that a worker can generate larger error when observing and adjusting the hydraulic support by naked eyes in the coal mining process is avoided.
According to the scheme II, the limiting assembly comprises a screw and a nut, a through hole is formed in the bottom end of the sleeve, the nut is welded to the sleeve, the nut is opposite to the through hole, the screw is in threaded connection with the nut, when the sleeve moves to a corresponding position on the L-shaped supporting rod, the screw is rotated, the end portion of the screw is abutted to the L-shaped supporting rod, and the sleeve is fixed.
According to the scheme III, the L-shaped supporting rod is provided with the scale marks, the sleeve is provided with the reading holes, workers can adjust the positions of the sleeves on other auxiliary devices according to the sleeve positions of the auxiliary devices connected to the initial hydraulic support, and the sleeves can be accurately moved by arranging the scale marks, so that the accuracy of the moving distance is improved.
According to the scheme IV, the scheme is the optimization based on the scheme, one end of the L-shaped supporting rod is connected with a limit nut in a threaded mode, after the hydraulic support is arranged and the auxiliary device for straight use is used, the limit nut is rotated, the limit nut is unscrewed from the L-shaped supporting rod, and then the sleeve and the arc-shaped rod are detached.
The fifth scheme is the optimization of the fourth scheme, a rotary handle is arranged at the end part of the screw rod, and the rotary handle is convenient for a worker to rotate the screw rod.
