The top of described telescopic boom is provided with the rail hydraulic ram, and an end of described upper 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 upper rail hydraulic ram and telescopic boom are installed an end of the first pulley.

The beneficial effect that the utility model compared with prior art has is: adopt hydraulic drive lever construction scissor-type cab lifter to realize the monorail crane cab lift, the compact conformation stroke is large; The use of two groups of scissor columns makes the pulley track stable action, and the reliability of lifter is large; Scissor column is articulated in up and down on the pulley, and is not easy to wear being used by pulley and pulley track up and down, and increase service life; Operating personal directly enters operator's compartment one button and automatically rises, and is easy to operate.

Description of drawings

Be described in further detail below in conjunction with the specific embodiment of accompanying drawing to the utility model cab lifter:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1;

Use constitution diagram when Fig. 3 is the elongation of the utility model cab lifter;

Use constitution diagram when Fig. 4 is the contraction of the utility model cab lifter;

Among the figure: 1 is the top sheave track, and 2 is upper rail hydraulic ram, and 3 is parallel rod, and 4 is telescopic boom, and 5 is hydraulic ram, and 6 is the lower sheave track, and 7 is the first pulley, and 8 is the second pulley.

The specific embodiment

Cab lifter as depicted in figs. 1 and 2, comprise: top sheave track 1, parallel rod 3, telescopic boom 4, hydraulic ram 5, lower sheave track 6, the first pulley 7 and the second pulley 8, described two groups of telescopic booms 4 be arranged in parallel, the top of every group of telescopic boom 4 all is connected with a top sheave track 1 separately, the bottom of every group of telescopic boom 4 all is connected with a lower sheave track 6 separately, described telescopic boom 4 is a plurality of vertically stacked scissor columns of fork of cutting of two row, and two row scissor columns all are connected with parallel rod 3 between the corresponding hinged place; One end of described telescopic boom 4 bottoms is articulated on the lower sheave track 6, and the other end that telescopic boom 4 bottoms are equipped with the first pulley 7 cooperates with lower sheave track 6; One end at described telescopic boom 4 tops is articulated on the top sheave track 1, and the other end that telescopic boom 4 tops are equipped with the second pulley 8 cooperates with top sheave track 1; Described hydraulic ram 5 is positioned at the middle part of telescopic boom 4, and is parallel with lower sheave track 6 with top sheave track 1, and the cylinder body of hydraulic ram 5 is connected parallel rod 3 connections with the corresponding hinged place of two row scissor columns with piston rod.

The top of described telescopic boom 4 is provided with rail hydraulic ram 2, and an end of described upper rail hydraulic ram 2 is hinged on the hinge of telescopic boom 4 tops and top sheave track 1, and an end of the other end of upper rail hydraulic ram 2 and telescopic boom 4 installations the first pulley 7 is hinged.

Shown in Fig. 3 and Fig. 4 use constitution diagram of the present utility model, the top sheave track 1 of described cab lifter top is fixed on the monorail crane walker, and the lower sheave track 6 of below is fixed on the monorail crane operator's compartment top board.
