Abstract

The utility model discloses an automatic blocking type limit device suitable for preventing a tramcar from running backwards. The automatic blocking type limit device comprises a base (5) and a blocking arm (3), and the base (5) and the blocking arm (3) are matched in a hinged mode. The blocking arm is matched with the base and of a pitching type structure, so that tramcar wheels firstly are contacted with a balancing bearing end of the blocking arm, then run over a pin shaft to enable the blocking arm to overturn, and then run over a buffering baffle of the blocking arm, and finally the balancing bearing end falls down through self weight, the buffering baffle automatically lifts up, and the tramcar is right prevented from running backwards. The automatic blocking type limit device is simple in structure, low in manufacturing cost, simple and convenient to install, stable and reliable in work, and capable of effectively preventing the tramcar from running backwards, avoids safety accidents, saves labor cost, and improves mining efficiency and economical benefits.

Description

A kind of automatic blocking type inhibiting device that is suitable for the mine car anti-reverse
Technical field
The utility model belongs to mine accessory equipment technical field, is specifically related to a kind of simple in structurely, and cost of manufacture is cheap, the safe and reliable automatic blocking type inhibiting device that is suitable for the mine car anti-reverse.
Background technology
Interior shaft is carried in the operation process of ore deposit, mine car need be pulled out from cage.For preventing to slide back interior shaft once more after mine car from pulling out, mine car takes place weigh down safety misadventures such as well, corresponding anti-reverse mine car inhibiting device must be set at the well head place.Mostly the mine car inhibiting device of prior art is by the manual worker's operation of people, uses both inconveniently, and needs staff on duty, increases cost of labor, also safety inadequately.For this reason, develop a kind of simple in structurely, safe and reliable, and the automatic spacing device that can independently move is the key point that overcomes the prior art deficiency.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and cost of manufacture is cheap, simple installation, and stable and reliable operation is suitable for the automatic blocking type inhibiting device of mine car anti-reverse.
The purpose of this utility model is achieved in that and comprises pedestal and stop arm that described stop arm cooperates with pedestal is hinged.
The utility model is taked to face upward the bow stop arm of formula structure and is cooperated with pedestal, make tramcar wheel at first contact the balance socket end of stop arm, ground bearing pin then and made the stop arm upset, ground the cushioning fender of stop arm afterwards, last balance socket end falls with deadweight, cushioning fender lifts automatically, stops that just mine car falls back.The utility model is simple in structure, and cost of manufacture is cheap, simple installation, and working stability is reliable, can effectively prevent the mine car reversing, avoids the generation of safety misadventure; Save human cost, improve mining efficiency and economic benefit.
Description of drawings
Fig. 1 is the utility model integral structure scheme drawing;
Fig. 2 is the utility model running condition scheme drawing;
Among the figure: 1-cushioning fender, 2-balance holding arm, 3-stop arm, 4-bearing pin, 5-pedestal.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, but never in any form the utility model is limited, any conversion or replacement based on the utility model training centre is done all belong to protection domain of the present utility model.
As shown in Figure 1 and Figure 2, the utility model comprises pedestal 5 and stop arm 3, described stop arm 3 and 5 hinged cooperations of pedestal.
Described stop arm 3 one ends are provided with balance holding arm 2, and the other end is provided with cushioning fender 1.
Described stop arm 3 is the centering type structure, and an end is long-armed, and an end is a galianconism, and its center of gravity is at close galianconism end, bearing pin and 5 hinged cooperations of pedestal that centroidal is provided with.
Described stop arm 3 is curved, and the galianconism end is a balance holding arm 2, and its sinking also contacts work with pedestal and cooperates.
Described long arm end be upwarp attitude and with 1 affixed cooperation of cushioning fender.
Described cushioning fender 1 driving surface is vertical state.
On the described pedestal 5 fixed bolt hole is set, so that it is cooperate, that pedestal 5 is fixing with lower margin or bolt of rear end plate.
The utility model principle of work and working process:
The utility model is taked to face upward the bow stop arm of formula structure and is cooperated with pedestal, make tramcar wheel at first contact the balance socket end of stop arm, ground bearing pin then and made the stop arm upset, ground the cushioning fender of stop arm afterwards, last balance socket end falls with deadweight, cushioning fender lifts automatically, stops that just mine car falls back.The utility model has overcome the drawback that the prior art limiting device needs staff on duty, starts automatically, and the reliability height is specially adapted to mine car anti-reverse control, avoids the generation of safety misadventure.
