Inclined shaft transport vehicle rail holding self-tightening device

Abstract

The invention discloses an inclined shaft transport vehicle rail holding self-tightening device. The inclined shaft transport vehicle rail holding self-tightening device comprises a trigger spring mechanism, an unhooking mechanism and a brake locking mechanism. The trigger spring mechanism is connected with a traction rod of a transport vehicle and the unhooking mechanism, the unhooking mechanismis connected with the brake locking mechanism through a second connecting steel wire rope. The inclined shaft transport vehicle rail holding self-tightening device has the advantages of adopting the mechanical principle, and being free of power, easy and convenient to operate, convenient to mount and maintain, safe and reliable in property, easy and convenient to operate and being free of turningover during braking.

Description

technical field [0001] The invention relates to the technical field of hydropower engineering construction, in particular to a rail-holding self-tightening device for inclined shaft transport vehicles, in particular to a rail-holding self-tightening device for inclined shaft construction transport vehicles used for water conservancy construction and transportation of metal or non-metal mines below 60 degrees. tighten the device. Background technique [0002] According to the relevant regulations on the transportation safety of inclined shafts in coal mines and non-coal mines, the mandatory requirements of the construction unit and the consideration of the construction unit's own safety, all main and auxiliary inclined shafts that are transported by string vehicles must be equipped with "one slope and three gears" supporting devices , but at present, in the lifting and transportation of inclined shafts in domestic mines, there is still no special device for anti-sports cars i...

Problems solved by technology

Before the present invention, several anti-car devices used in inclined shafts of mines had their own characteristics, such as radar monitoring devices, infrared photoelectric sensing devices and speed sensors, etc., although they could effectively prevent car device accidents and ensure that operators Or the safety of the equipment, but the disadvantage is that the production cost is high and the installation, debugging and maintenance are complicated. The electronic products used in the equipment have poor dust resistance and corrosion resistance. Malfunction, failure or misoperation at a critical moment

Recently, there are ZL200620051989.X "a new type of anti-running device for inclined shafts" and ZL200720063574.9 "an instant anti-running device installed on mine cars". They have their own characteristics and bring good news to coal mine safety. But their disadvantage is that they are braked by inserting rail sleepers. When the angle of the transport slope exceeds 35 degrees, the braking effect will not be achieved and the serious situation of rolling down and rolling will occur.
