Abstract

The utility model belongs to the technical field of mining machinery equipment, concretely relates to semi-controllable formula of group chain car puller among mine vertical hoisting system pushes away the head. The vehicle body is provided with a guide rod, the guide rod is connected with the vehicle body through a pin shaft, a spring is sleeved on the guide rod, and the end part of the guide rod is inserted into the sleeve. The self-recovery is realized when the normal cart is pushed into the tank, the failure rate caused by manual frequent control is reduced, the controllability is realized when the tank is pushed into the tank, and the mine car can smoothly pass through the front rail. The utility model has the advantages of flexible use, strong universality, simple use and reliable work.

Description

Half controllable type is cut somebody's hair

Technical field

The utility model belongs to the mine mechanism technical field, and half controllable type that is specifically related to group chain type car puller in the mine vertical shaft elevator system is cut somebody's hair.

Background technology

In recent years, group chain type car puller is used widely in the colliery owing to series of advantages such as can advancing jar go-cart, it is one of important components of car puller that car puller is cut somebody's hair, and its effect is directly to promote mine car, and the mine car that cage is outer pushes cage or the mine car in the cage is released.

Current, the widely used form of cutting somebody's hair mainly contains two kinds in the group chain type car puller: a kind of is that complete controllable type is cut somebody's hair, this principle of work of cutting somebody's hair is when being in full state when pawling, car puller is the direction of cage (mine car pack into) motion forward, makes pawling to be in and lifting the go-cart mode of operation of cutting somebody's hair but play jaw arrangement; When car puller when (mine car pack into the opposite direction of cage) operation is by the mine car bottom backward, the mine car axle can will be pawled and be depressed and pawl and can not recover to lift state automatically; Another kind of cutting somebody's hair of form is that self-resetting type is cut somebody's hair, this principle of work of cutting somebody's hair is that pawling of cutting somebody's hair always is in the state of lifting because counterweight or action of the spring make to pawl, the car puller ahead running can carry out go-cart, the mine car axle will be pawled and be depressed when car puller moves by the mine car bottom backward, behind mine car, pawl because counterweight or action of the spring still make to pawl and lift.Before a kind of work of cutting somebody's hair flexible, applied range, the deficiency of its existence is all will be by playing the jaw arrangement effect when each go-cart, artificial control frequently causes some critical components often to damage, the fault rate height easily.Though a kind of reliable operation of cutting somebody's hair in back, fault rate is low, and its shortcoming is to cut somebody's hair to realize jar go-cart when travelling forward on the impassabitity track bottom the mine car, uses limited.

Summary of the invention

The purpose of this utility model provides a kind of applying flexible, service-strong half controllable type car puller is cut somebody's hair.

The utility model is achieved through the following technical solutions:

Be that a kind of half controllable type is cut somebody's hair, comprise pawl, car body, it is hinged by bearing pin with car body to pawl, and the car body bottom is provided with roller, it is characterized in that the bottom of pawling is provided with sleeve, sleeve is by bearing pin and pawl hinged, car body is provided with pilot bar, and pilot bar is connected with car body by bearing pin, is nested with spring on the pilot bar, insert in the sleeve end of pilot bar, and car body has been provided with the pawl pusher dog.

Slideway has been provided with jaw arrangement.

Pilot bar of the present utility model and car body, sleeve and pawl respectively hinged by bearing pin, it is hinged by bearing pin and car body to pawl, form one three hinge structure, make spring be in compressive state all the time, when moving backward when cutting somebody's hair, pawl by mine car when bottom because the mine car axle can not be zero point of transition with pawling to pressing down spring and focusing on certainly of the pawling resultant moment that the bearing pin place produces, so behind the mine car bottom, resultant moment in counterweight and spring generation can make the recovery of pawling lift state, have from renaturation, have the advantages that the self-resetting type car puller is cut somebody's hair; Travel forward when cutting somebody's hair and to depress pawling artificially in the time of to pass the mine car bottom, at this moment, spring and pawl that to cross moment be zero point from focusing on resultant moment that the bearing pin place produces, produce with making to pawl and lift opposite resultant moment, making under the effect of this resultant moment pawls is in full state, assurance is cut somebody's hair successfully and to be passed through from the mine car bottom, and makes and pawl that upwards to cross resultant moment once more be zero point by playing jaw arrangement after by mine car, and making pawls lifts.Increased people's participation though fully controllable type is cut somebody's hair need pass the mine car bottom time cutting somebody's hair to travel forward, the utlity model has use flexibly, highly versatile, use simply, the advantage of reliable operation, can be widely used in mine mining field.

Description of drawings

Figure 1 shows that pawl structural representation when lifting of the utility model;

Figure 2 shows that pawl structural representation when falling of the utility model.

As shown in drawings: 1 car body, 2 is pawled, 3 sleeves, 4 pilot bars, 5 springs, 6 rollers, 7 pawl pusher dogs, 8 jaw arrangements.

The specific embodiment

As shown in Figure 1 and Figure 2: car body 1 is provided with pawls 2, it is 2 hinged by bearing pin and car body 1 to pawl, and car body 1 is provided with

roller

6, and 2 the bottom of pawling is provided with sleeve 3, sleeve 3 by bearing pin with pawl 2 hinged, car body 1 is provided with pilot bar 4, and pilot bar 4 is hinged by bearing pin and car body 1, is nested with spring 5 on the pilot bar 4, spring 5 is in compressive state, insert in the sleeve 3 end of pilot bar 4, and car body 1 has been provided with pawl pusher dog 7, and slideway has been provided with jaw arrangement 8.

When the utility model used, when needs during backward by the mine car bottom, the axletree of car body 1 was depressed and is pawled 2, by after pawl and 2 under the effect of spring 5, recover to lift state; When needs forward when the mine car, artificially will pawl and 2 depress, cross the point of transition of 2 torques of pawling, described point of transition is meant to pawl and can compresses the spring into the shortest position, then pawls 2 to keep full state; Behind mine car, play jaw arrangement 8 and acted on pawl pusher dog 7, playing pawl pusher dog 72 produces and makes 2 moments of lifting of pawling overcome spring 5 and moments that 2 deadweights of pawling produce make to pawl and 2 lift the point of transition of crossing 2 the torque of pawling once more by acting on to pawl, under the effect of spring 5, make 2 recoveries of pawling lift state, proceed the go-cart operation.

Claims

1. one and half controllable types are cut somebody's hair, comprise pawl, car body, it is hinged by bearing pin with car body to pawl, and the car body bottom is provided with roller, it is characterized in that the bottom of pawling is provided with sleeve, sleeve is by bearing pin and pawl hinged, car body is provided with pilot bar, and pilot bar is connected with car body by bearing pin, is nested with spring on the pilot bar, insert in the sleeve end of pilot bar, and car body has been provided with the pawl pusher dog.
