Embodiment Construction

[0024] The present invention will be further described below in conjunction with drawings and embodiments.

[0025] As shown in the drawings, the normally closed buffer car catcher includes a mounting base 1, a moving frame 2, a shaft hook 3, a trigger seat 4, a trigger 5, a positioning protector 6, a cylinder 7, a buffer spring 8, a stop Axle 9, shaft-holding hook self-locking device 10, shaft-holding hook rotating shaft 11, connecting shaft 12, trigger seat rotating shaft 13, spring guide seat 14 and guide seat shaft 15.

[0026]Mounting seat 1 is a rectangular frame, with baffles 17 below the two ends of the frame, fixed plates 20 on the two ends of the frame, bolt holes 21 on the fixed plates 20, and support stoppers on the rear of the two side walls of the frame. The elongated hole 18 of axle, the front portion of frame two side walls has the elongated hole 19 of supporting guide seat axle, has two guide holes 16 on the fixed seat front end wall. The mobile frame 2 is a ...

Abstract

Provided is a normally-closed type buffer tramcar retarder. The normally-closed type buffer tramcar retarder comprises a mounting base, a movable frame, a journal sticking mechanism, a trigger mechanism and a buffer mechanism, wherein the movable frame is installed inside the mounting base through stopping shafts and guiding base shafts, the movable frame can move forward and backward in the mounting base, one end of the movable frame abuts against the mounting base through buffer springs, the journal sticking mechanism is composed of journal sticking hooks, journal sticking hook rotary shafts and self-locking devices, and the trigger mechanism is composed of a trigger base, a trigger, an air cylinder and trigger base rotary shafts. The normally-closed type buffer tramcar retarder has the advantages that the structure is simple and compact, and compared with a tramcar blocking column, the occupied space is reduced and cost is low. Due to the fact that the movable frame and a fixed frame are connected through springs, buffer tramcar retard is achieved. Due to the fact that the normally-closed type buffer tramcar retarder is in a closed state all the time when in a normal condition, the requirement that a tramcar blocking device needs to be in a normally-closed state is met. Due to the fact that the normally-closed type buffer tramcar retarder can retard a rear axle of a tramcar, the tramcar is prevented from tipping.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to a mine car safety protection device, in particular to a car catcher for a mine car when it is a sports car. Background technique [0002] In the inclined shaft transportation, the mine car runs at a constant speed under the traction of the winch. If the mine car is decoupled or the traction wire rope breaks, it will cause a sports car accident. After the mine car runs, it will cause great harm to the personnel in the mine and the equipment. cause great damage. In the prior art, in order to reduce the danger and injury behind the sports car, a car barrier is provided on the mine car track, and the mine car is caught with the car barrier. The disadvantage of the prior art is that the car barrier occupies a large area and basically can only be used once, and the structure of the car barrier itself will be destroyed after the car is caught. Contents of the inv...
