Abstract

A anti-shock tank cage jump set applied in the mine provided pertains to a lift well equipment of mine composed of a horizontally arranged cage jump set arm. The life well equipment is characterized in that the external sides of the front end of the cage jump set arm are respectively arranged with step-like joining blocks synchronously; the joining blocks are, via pin shafts, hinged with the tip of the cage jump set and clump weights which combines together with the cage jump set, with the tip of the cage jump set positioned at the inner side of the cage jump set arm and simultaneously on the same central line with cage jump set arm and the clump weights arranged at the outer sides of the joining blocks. The tip of the cage jump set and clump weights which combines together with the tip of the cage jump set are also in a step-like structure respectively. When the utility model is used, a cage holding the tank in a downward operation will drive the tip of the cage jump set rotate downward along the direction of the pin shaft till the cage passes by the tip of the cage jump set even if the cage is imposed with a wrong operation, thereby ensuring the safe operation of the cage and putting an end to the occurrence of tank shock phenomenon. Thanks to the fact that the utility model needs only an improvement based on the cage jump set existing in prior art, the utility model also has the advantages of a simple structure and a high reliability.

Description

Mine dropping-down-proof pot cage chair

Technical field

The utility model belongs to the hoistway equipment of mine, specifically is a kind of mine dropping-down-proof pot cage chair.

Background technology

Cage is that mine is than indispensable lifting means, lifting means at the main personnel of ore, equipment, ore, and cage chair is the major equipment supporting with cage, at present in the normal productive process of each mine, because cage is in lifting process, improper or the cage chair failure and other reasons of operating personal operation, the accident of crouching jar takes place extremely easily, and promptly the cage card is pressed on the cage chair, not only damages cage chair, and influenced the normal use of cage chair, have a strong impact on the safe operation of elevator system.Therefore, the cage chair of prior art is transformed, designed a kind of safe and reliable novel cage chair with regard to needing technical personnel.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of operation that can guarantee cage safety is provided, thoroughly stop jar phenomenon of squatting, only need the prior art cage chair is transformed, and mine dropping-down-proof pot cage chair simple in structure, that unfailing performance is good.

For achieving the above object, the utility model is achieved through the following technical solutions:

It is a kind of mine dropping-down-proof pot cage chair, comprise the cage chair arm that be arranged in parallel, the outside that it is characterized in that cage chair arm leading section is symmetrical arranged the coupling block that is step-like with it respectively, on the coupling block by the hinged cage chair of bearing pin point and with the balance weight body of cage chair point one, the cage chair point is positioned at cage chair arm inboard, and be positioned on the same line of centers with the cage chair arm, balance weight body is positioned at the outside of coupling block, cage chair point and with it the balance weight body of one also be step-like structure.

For the fastness of strengthening connecting between cage chair point and the balance weight body, and be convenient to install, cage chair point and the balance weight body horizontal section at the pin shaft hole position is n shape structure connection bridge, and coupling block is provided with the Ka Tai with this connection bridge coupling, joins bridge and is buckled on the Ka Tai.

In addition, can rotate normally in order to guarantee the cage chair point, cage chair point and the position that the cage chair arm faces mutually are processed as the convex structure of mutual coupling respectively.

In order to alleviate the weight of cage chair point, the cage chair point is resetted under the effect of balance weight body fast, can make the horizontal structure triangular in shape of cage chair point leading portion.

After the utility model is used, even if cage maloperation, will drive the cage chair point when cage is descending rotates along bearing pin, until passing through the cage chair point, thereby can guarantee the operation of cage safety, thoroughly stop jar phenomenon of squatting, owing to only need the prior art cage chair is transformed, so also have advantage simple in structure, that unfailing performance is good.

Description of drawings

Fig. 1: the utility model example structure scheme drawing.

The A-A of Fig. 2: Fig. 1 is to structural representation.

Fig. 3: the utility model running condition reference diagram.

Among the figure: 1 cage chair point; 2 bearing pins; 3 coupling blocks; 4 balance weight body; 5 cage chair arms; 6 bridges.

The specific embodiment

As Fig. 1, shown in Figure 3, this mine dropping-down-proof pot cage chair, comprise the cage chair arm 5 that be arranged in parallel, the outside that it is characterized in that cage chair arm 5 leading sections is symmetrical arranged the coupling block 3 that is step-like with it respectively, on the coupling block 3 by the hinged cage chairs point 1 of bearing pin 2 and with the balance weight body 4 of cage chair point 1 one, cage chair point 1 is positioned at cage chair arm 5 inboards, and is positioned on the same line of centers with cage chair arm 5, balance weight body 4 is positioned at the outside of coupling block 3, cage chair point 1 and with it the balance weight body 4 of one also be step-like structure.

At the cage of mine in the decline process, when improper the or cage chair failure and other reasons of operating personal operation took place, along with the quick decline of cage, cage touched cage chair point 1, cage chair point 1 just is pressed down thereupon as shown in Figure 3, rotate along bearing pin 2, balance weight body 4 is upturned, after cage passes through cage chair point 1, cage chair point 1 resets under the effect of balance weight body 4, recover normal mode of operation, thereby avoided the generation of crouching jar phenomenon, the job procedure when cage rises is same as the prior art.

For the fastness of strengthening connecting between cage chair point 1 and the balance weight body 4, and be convenient to install, cage chair point 1 and the horizontal section of balance weight body 4 at position, bearing pin 2 hole are n shape structure connection bridge 6, and coupling block 3 is provided with the Ka Tai with this connection bridge 6 couplings, and connection bridge 6 is buckled on the Ka Tai.

In addition, can rotate normally in order to guarantee cage chair point 1, cage chair point 1 and the position that cage chair arm 5 faces mutually are processed as the convex structure of mutual coupling respectively.

In order to alleviate the weight of cage chair point 1, cage chair point 1 is resetted under the effect of balance weight body 4 fast, can make the horizontal structure triangular in shape of cage chair point 1 leading portion.

After the utility model is used, even if cage maloperation, cage is descending to strike the cage chair point at 1 o'clock, will drive cage chair point 1 rotates along bearing pin 2, pass through cage chair point 1 until cage, thereby can guarantee the operation of cage safety, thoroughly stop jar phenomenon of squatting, owing to only need the prior art cage chair is transformed, so also have advantage simple in structure, that unfailing performance is good.

Claims
