Description

Technical Field

[0001] The utility model relates to the field of matching components of mining ventilation equipment, in particular to a step-type slideway self-moving device. Background Art

[0002] The wind tube is a common equipment for underground ventilation and is also the main equipment. As the mining face advances, the front end of the wind tube needs to be advanced along with it. In the prior art, the wind tube is usually suspended by a track and manually pulled and displaced to achieve the forward delivery of the wind tube. However, this method has certain disadvantages, the most important of which is that the underground environment is complex and involves multiple implementation conditions. Manual operation is very unfavorable for implementation safety. In addition, manual pulling uses the wind tube as the gripping part to push forward, and the pulley in the top slide may be stuck, resulting in inconvenience in pulling and waste of manpower. In view of the above situation, there is currently a lack of corresponding solutions. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a step-type slide self-moving device which has a simple structure, is assembled in a slide, uses mechanical power to achieve self-propelled movement or retreat, and thereby pulls the air duct to achieve air duct position adjustment.

[0004] The equipment includes a telescopic arm, which is the assembly basis of the equipment and also a self-propelled power device;

[0005] The telescopic arm comprises a cylinder sleeve and a piston, and an external support type locking mechanism is hingedly provided at the rear end of the cylinder sleeve and the end of the piston respectively;

[0006] The externally supported locking mechanism comprises a central plate, and open wing plates are arranged on both sides of the central plate, and springs are arranged between the open wing plates.

[0007] The effect achieved by this is that the telescopic arm stretches out, the cylinder sleeve and the piston part move toward each other, the external support locking mechanism at the rear end of the cylinder sleeve is locked, that is, it is fixed in the slideway by tightening, and the piston part moves forward;

[0008] The telescopic arm retracts, the external support locking mechanism at the piston end is locked, and the cylinder sleeve moves forward; the above actions are repeated to realize the step-by-step self-movement of the equipment in the slideway.

[0009] The beneficial effects of the utility model are as follows: the utility model has a simple structure and low cost. It changes the propulsion mode or propulsion form of the wind tube in the prior art with a simple structure, can embed the telescopic arm part into the sliding sleeve, and realize the self-propelled start and stop of the equipment with a control valve, thereby replacing the manual pulling of the wind tube, which can greatly improve the construction safety and pulling convenience. It has great safety promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
