Description

A kind of fixing device for preventing mine head sheave from offseting

Technical field

This utility model belongs to mine production equipment technical field, and in particular to a kind of for prevent mine head sheave skew Fixing device.

Background technology

In mine production system, head sheave is the fixed pulley that mine vertical derrick the top adjusts the steel wire rope direction of motion, Effect is to prop up the steel wire rope for connecting lifting drum and hoisting container, and the steering of guiding steel wire rope.Transport in lifting drum In capable process, shift due to lifting centrage or cage guide, the rotation of single wire rope unbalance stress, day wheel shaft does not freely cause The reason such as head sheave bounce so that the position of head sheave produces skew.After head sheave deflects away from initial position, lift system will be run not Stable, steel wire rope will produce friction with peripheral member, be easily damaged, and when serious, steel wire rope disconnects, and industrial accident occurs.

Utility model content

The purpose of this utility model is to provide a kind of fixing device for preventing mine head sheave from offseting, can be effectively Prevent mine head sheave from offseting, and can change at any time.

This utility model is adopted the following technical scheme that：

A kind of fixing device for preventing mine head sheave from offseting, including two bearing blocks, head sheave, rotary shaft, Yi Jiyong In the support beam of the fixation bearing block, the bearing block is symmetricly set in the head sheave both sides, and the head sheave is sheathed on rotation On the axle and two ends of rotary shaft are inserted in the bearing block, and the both sides of each bearing block are arranged with fixture, described solid Determine part to be fixedly connected in support beam and spaced between fixture and bearing block, in the interval, be provided with wedge, described Tight fit is between wedge and fixture and bearing block, and is connected by spot welding between wedge and fixture.

The above-mentioned fixing device for preventing mine head sheave from offseting, the cross section of the wedge is right-angled trapezium, wedge Shape part is risers near the side of bearing block and is mutually fitted close with the side of bearing block by the risers that wedge is close The side of fixture is that prism the end by the prism with fixture are fitted close, and fixture is near the end of wedge Portion is provided with the angled end-face being adapted with the prism.

The above-mentioned fixing device for preventing the skew of mine head sheave, the fixture is by being fixedly welded on support beam On.

The beneficial effects of the utility model are as follows：

（1）This utility model will be fixed for the position of bearing block by the cooperation of fixture and wedge, so as to by day The position of wheel is fixed, and coordinates very closely, can be effectively prevented mine day between bearing block, wedge and fixture three Wheel skew；

（2）In this utility model, connected by spot welding between wedge and fixture, the mode of spot welding connection can either rise To fixation, prevent the probability that mutually slides between wedge and fixture, both companies can be released again when needed Relation is connect, when for example changing wedge, squeezing into or get wedge；

（3）In this utility model, coordinated by inclined-plane between wedge and fixture, the broad-ruler of the cross section of wedge The very little controllable adjustment for gradually increasing, can realizing degree of cooperation between bearing block and wedge, specifically when bearing block and wedge When there is gap between shape part, wedge can be squeezed into elimination gap further downward, when matching somebody with somebody between bearing block and wedge When closing tension, wedge can be got slightly up；

（4）In this utility model, wedge is the easy-abrasion part in whole device, consumes caused by head sheave skew Local stress, reduce friction between steel wire rope and peripheral member when head sheave offsets to a certain extent, it is to avoid steel wire rope Damage or disconnect so that the problem of industrial accident, and wedge low cost, it is simple to manufacture, it is convenient to change.

In sum, this utility model can be effectively prevented the skew of mine head sheave, it is to avoid the generation of security incident, in ore deposit There is higher practical value in well production.

Specific embodiment

In order that technical purpose of the present utility model, technical scheme and beneficial effect are clearer, below in conjunction with the accompanying drawings and Specific embodiment is further illustrated to the technical solution of the utility model.

As illustrated in fig. 1 and 2, a kind of fixing device for preventing mine head sheave from offseting, including two bearing blocks 3, head sheave 2nd, rotary shaft 4 and the support beam 1 for fixing the bearing block 3, the bearing block 3 are symmetricly set in 2 liang of the head sheave Side, the head sheave 2 is sheathed in rotary shaft 4 and the two ends of rotary shaft 4 are inserted in the bearing block 3, and the two of each bearing block 3 Side is arranged with fixture 5, and the fixture 5 is fixedly connected by welding in support beam 1 and fixture 5 and bearing block 3 Between spaced, be provided with wedge 6 in the interval, be between the wedge 6 and fixture 5 and bearing block 3 tight Connected by spot welding between close fit, and wedge 6 and fixture 5.The longitudinal section of the wedge 6 be right-angled trapezium, right angle Trapezoidal water table opening is more than base square, and wedge 6 is risers 61 near the side of bearing block 3（Corresponding right-angled trapezium Right angle waist）And be mutually fitted close by the risers 61 and the side of bearing block 3, wedge 6 is oblique near the side of fixture 5 Side 62（The oblique waist of corresponding right-angled trapezium）And the end by the prism 62 with fixture 5 is fitted close, fixture 5 is close The end of wedge 6 is provided with the angled end-face being adapted with the prism, and the lateral dimension of wedge 6 gradually becomes with prism 62 Change, gradually increase from bottom to top.

It should be noted last that：Above-described embodiment is merely to illustrate and unrestricted the technical solution of the utility model, appoints Equivalent and the modification without departing from this utility model spirit and scope or local replacement that what is carried out to this utility model, which is equal Should cover within this utility model protective scope of the claims.
