Generic constraint inclined limiting guide telescoping leg-type booster with buffer function

Abstract

The invention discloses a generic constraint inclined limiting guide telescoping leg-type booster with a buffer function. The booster comprises an inclined telescoping leg mechanism, a direction limiting guide mechanism and a system buffer mechanism. A leg boot of the inclined telescoping leg mechanism is connected to the front end of the inner arm of a telescoping leg in a sliding chute way, the outer arm of the telescoping leg is connected to the inner arm of the telescoping leg in a sliding sleeving way, a main hydraulic cylinder is hinged to the outer arm of the telescoping leg, and a piston rod is hinged to the inner arm of the telescoping leg. A guide groove displacement hydraulic cylinder of the direction limiting guide mechanism is hinged to a swinging seat of a heading machine walking rack, one end of the direction limiting guide trough plate is hinged to the walking rack, the other end of the direction limiting guide trough plate is hinged to a piston rod of the guide groove displacement hydraulic cylinder, and one end of a guiding wheel shaft is hinged to the inner arm of the telescoping leg. The rear end of the screw of the system buffer mechanism is hinged to the heading machine walking rack, a spring preloading adjustment cardboard sleeves the front part of the screw, one end of the spring preloading adjustment cardboard presses against a nut in front of the fastening screw and the other end presses against a buffer spring. The generic constraint inclined limiting guide telescoping leg-type booster has a reasonable structure, realizes reasonable coupling of base plate pressure and horizontal thrust and obviously improves boosting effects.

Description

technical field [0001] The invention relates to a booster used on a roadheader to assist the work of the roadheader, in particular to a general-constraint oblique-direction-limited-guidance telescopic-leg type booster with a buffer function. Background technique [0002] It is suitable for the roadheader booster in mines, tunnels, coal mines and related engineering operations. It uses the booster foot to realize the auxiliary boost function for the roadheader to move forward through the reaction force generated by pushing the roadway floor. The existing boosters in the market are relatively easy to design and realize in action, but there are many problems, such as: the unreasonable matching between the booster’s pressure on the bottom plate and the horizontal thrust, complex structure, and poor boosting effect, especially in some mines. When the condition of the roadway floor is not good, the crawler belt of the roadheader cannot effectively grasp the roadway floor, causing ...

Problems solved by technology

The existing boosters in the market are relatively easy to design and realize in action, but there are many problems, such as: the unreasonable matching between the booster’s pressure on the bottom plate and the horizontal thrust, complex structure, and poor boosting effect, especially in some mines. When the condition of the roadway floor is not good, the crawler belt of the roadheader cannot effectively grasp the roadway floor, causing the equipment to slip on the spot and unable to climb the slope, which brings great difficulties to the climbing and reversing of the large-slope roadway
