Abstract

The invention discloses a liftable cab of a monorail crane, comprising a walking bar, a lifter, a cab and a mousing-hook self-locking device. The liftable cab of the monorail crane is located at the head of the monorail crane; the walking bar arranged above the cab is matched with a monorail crane rail suspended on a coal mine tunnel roof; the walking bar, the lifter and the cab are connected in sequence from top to bottom; the cab is ascended or descended through controlling the stretching of the hydraulic control lifter; and the safety of the cab can be effectively improved by adopting the mousing-hook self-locking device arranged on the roof of the cab. According to the invention, the lifter with the lever structure is pushed by adopting hydraulic pressure so as to realize the ascending or descending of the cab; the liftable cab is compact in structure and large in stroke; a person can directly enter into the cab to operate; and the defect that the person needs to climb a ladder to get in or out of the cab of the traditional monorail crane is made up.

Description

A kind of monorail crane liftable operator's compartment

Technical field

The present invention relates to a kind of monorail crane operator's compartment, especially a kind of later-model monorail crane liftable operator's compartment.

Background technology

Used monorail crane on the present colliery; Navigating mate all is that a ladder of stepping on the head gets into operator's compartment, because the monorail crane locomotive is on single track, to move, track is again to be fixed on the top board with chain; So navigating mate is very inconvenient up and down at cat ladder period of the day from 11 p.m. to 1 a.m meeting wigwag motion; And existing liftable operator's compartment mainly connects lifting mechanism with the operator's compartment bottom, and the below effect is that operator's compartment is risen, and is not suitable for the monorail crane of aerial work.

Summary of the invention

The present invention be directed to the deficiency of prior art, a kind of monorail crane operator's compartment that can automatic lifting is provided.

For solving the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of monorail crane liftable operator's compartment; Comprise: walker, lifter and operator's compartment; The walker of said operator's compartment top cooperates with the monorail crane track that on the coal mine roadway top board, hangs, and it is characterized in that: said walker, lifter, operator's compartment order are from top to bottom installed connection.

The structure of said lifter is: two groups of telescopic booms laterally arrange; The top of every group of telescopic boom all is connected with a top sheave track separately; The bottom of every group of telescopic boom all is connected with a lower sheave track separately; Said telescopic boom is that a plurality of vertically range upon range of forks of cutting of fork of cutting of two row are listed as, and two row are cut between the corresponding hinged place of fork row and all are connected with parallel rod; One end of said telescopic boom bottom is articulated on the lower sheave track, and the other end that the telescopic boom bottom is equipped with first pulley cooperates with the lower sheave track; One end at said telescopic boom top is articulated on the top sheave track, and the other end that the telescopic boom top is equipped with second pulley cooperates with the top sheave track; Said hydraulic ram is positioned at the middle part of telescopic boom, and with top sheave track and lower sheave parallel track, the cylinder body of hydraulic ram is cut the parallel rod of pitching the corresponding hinged place of row with two row respectively with piston rod and is connected; Described two top sheave tracks all are connected on the walker, and described two lower sheave tracks all are fixed on the top of operator's compartment.

The top of said operator's compartment also is equipped with the lock hook self-locking device; The structure of said lock hook self-locking device is: first adapter plate is fixed on operator's compartment top board one side; The bottom-hinged of driven hook is on first adapter plate, and second adapter plate is fixed on the operator's compartment top board opposite side, and the middle part of active hook is hinged on second adapter plate; One end of connecting rod and the middle part of driven hook are hinged; The other end of connecting rod and the middle and lower part of active hook are hinged, and an end of spring and the middle part of connecting rod are hinged, and the other end of spring is connected with the middle and upper part of active hook; The top of said active hook and driven hook is hook, the handle of the bottom of active hook for ease of holding; The bottom of said walker is provided with the boss that matches with said active hook, driven hook, and when being raised to top under the effect of operator's compartment at lifter, active hook and driven hook can hang on the described boss.

The top of said telescopic boom is provided with the rail hydraulic ram, and a said end of going up the rail hydraulic ram is hinged on the hinge of telescopic boom top and top sheave track, and it is hinged that the other end of last rail hydraulic ram and telescopic boom are installed an end of first pulley.

The beneficial effect that the present invention compared with prior art has is: monorail crane locomotive driving personnel can directly get into operator's compartment, need not step on ladder and get into operator's compartment; Lifter is realized cab lift, and the stroke macrostructure is compact, can realize automatic guidance, and easy to operate; The lock hook self-locking device makes many one mechanical protections of up-down operator's compartment, and is simple in structure and safe and reliable.
