Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic columns, in particular to a telescopic column for mining with high stability. Background Art

[0002] A hydraulic column is a retractable column that uses liquid pressure to generate working resistance and realize lifting and unloading. The hydraulic column is composed of a cylinder, a piston and a valve. The hydraulic column is used to control the drilling rig to maintain stability and adjust the drilling height and angle when drilling in the coal mining face. It is a structure used to support the mine pressure in the form of external load.

[0003] When using the existing hydraulic columns, due to the harsh working environment in the mine, coal slag sometimes falls onto the electroplating surface of the column during the mining process, damaging the column. A large amount of dust will also fall on the surface of the column, which is not conducive to the use of the hydraulic column, causing damage to the hydraulic column and affecting the stability of the hydraulic column. In view of this, we have proposed a telescopic column for mining with high stability. Utility Model Content

[0004] The purpose of the utility model is to provide a mining telescopic column with high stability to solve the problems raised in the above background technology.

[0005] In view of this, the utility model provides a mining telescopic column with high stability, comprising:

[0006] A bottom box, wherein two first semicircular tubes are slidably mounted on the top surface of the bottom box, and second semicircular tubes are slidably mounted in the two first semicircular tubes. A hydraulic column body is provided on the top surface of the bottom box, and the hydraulic column body is disposed in the two second semicircular tubes and the two first semicircular tubes, and a telescopic rod is provided on the hydraulic column body;

[0007] Two semicircular holes, the two semicircular holes are opened on the top surface of the second semicircular tube, and the two semicircular holes are movably connected to the outer side wall of the telescopic rod;

[0008] Two card slots, the two card slots are respectively opened on one side of the inner portion of the two second semicircular tubes, and card columns are fixedly installed on both sides of the telescopic rod, and the two card columns are movably connected to the two card slots respectively;

[0009] The adjusting component is arranged in the bottom box and is used to drive the two first semicircular tubes to move.

[0010] The top of the two sliders are respectively fixed with the bottom surfaces of the two first semicircular tubes, and the bottom ends of the two sliders are respectively fixed with the top surfaces of the two racks. When one of the racks moves, the two racks are meshed with the gears. At this time, the gears will rotate and drive the other rack to move. When the two racks move, the two sliders will drive the two first semicircular tubes to move. When the two first semicircular tubes move, the two first semicircular tubes and the two second semicircular tubes will be driven away from the hydraulic column body, and then the bolts on the mounting block are rotated to remove the hydraulic column body from the top surface of the bottom box.

[0011] In the above technical solution, further, a threaded rod is threadedly connected to one side of the bottom box, one end of the threaded rod is located outside the bottom box, and the other end of the threaded rod is rotatably connected to one end of one of the racks. When the threaded rod is rotated, one of the racks will be driven to move.

[0012] In the above technical solution, further, multiple mounting plates are fixedly installed on both sides of the base box, and multiple mounting holes are provided on the top surfaces of the mounting plates. By setting the mounting plates and the mounting holes, the base box can be easily installed and fixed, thereby improving the convenience of installing the base box.

[0013] In the above technical solution, further, a mounting block is fixedly installed at the bottom end of the hydraulic column body, and the mounting block is installed on the top surface of the bottom box by bolts. By providing the mounting block, it is convenient to install the hydraulic column body on the bottom box by bolts, which is convenient for disassembly and installation.

[0014] In the above technical solution, further, sealing strips are fixedly installed on one side of the two second semicircular tubes, the two first semicircular tubes and the two first semicircular tubes. When the two second semicircular tubes, the two first semicircular tubes and the two first semicircular tubes are closed, the sealing strips will increase the sealing between the two second semicircular tubes, the two first semicircular tubes and the two first semicircular tubes, prevent impurities from entering, and improve protection.

[0015] The beneficial effects of the utility model are:

[0016] 1. The highly stable mining telescopic column, when the telescopic rod is extended or retracted, the slot and the column are provided, and the slot and the column are sleeved together, which will drive the second semicircular tube to move on the first semicircular tube. Therefore, when the telescopic rod moves, the second semicircular tube will move with the extension and retraction of the telescopic rod. In addition, since the two semicircular holes are sleeved with the telescopic rod and sealing strips are provided in the semicircular holes, impurities can be prevented from entering when the telescopic rod is extended or retracted, thereby increasing the service life of the hydraulic column body. The provision of the first semicircular tube and the second semicircular tube also increases the protection effect of the hydraulic column body, thereby improving the service life of the hydraulic column body.

[0017] 2. The highly stable mining telescopic column, when the hydraulic column body needs to be disassembled and replaced, rotate the threaded rod. When the threaded rod rotates, it will drive one of the racks to move. When one of the racks moves, the two racks are engaged with the gear. At this time, the gear will rotate to drive the other rack to move. When the two racks move, the two first semicircular tubes will be driven to move through the two sliders. When the two first semicircular tubes move, they will drive the two first semicircular tubes and the two second semicircular tubes away from the hydraulic column body. Then rotate the bolts on the mounting block to remove the hydraulic column body from the top surface of the bottom box. BRIEF DESCRIPTION OF THE DRAWINGS
