Abstract

The utility model discloses non-road surface mobile hoisting machinery, and particularly relates to an improvement to a cab of a crawling crane. A hoisting mechanism is installed between the cab and a frame body to realize the hoisting of the cab, and the hoisting mechanism are composed of four parallel connecting rods organizations and driven by a power unit. In the construction operation, the automatic hoisting of the cab can be realized by just using an electromagnetic valve to drive the power unit when the height of the cab needs to be adjusted, without the need of the help of other people help, so that a driver can complete hoisting operation without the need of going out of the cab. The utility model has the advantages of simple structure, reasonable design, and convenient operation. Furthermore, the utility model expands the operation view field, improves the safety and the reliability, and meets the requirement of trailer transportation for the height limitation.

Description

The automatic lifting driver's cab of crawler crane
One, technical field
The utility model belongs to non-road surface movable crane tool, and what be specifically related to is improvement to the crawler crane driver's cab.
Two, background technology
In known technology, the driver's cab of crawler crane all is fixedly mounted on the vehicle frame mostly, and its position height can't be adjusted.The requirement of road limit for height in the time of so just can only satisfying trailer transportation, and safety, pulsation-free lifting can not satisfy chaufeur and in range of visibility, obstacle is arranged the time.At present, even if movably operator's compartment mechanically occurred at fork truck, Forklift, freight container handling machine etc., but it moves that all to be that armrest is moving regulate, and in operation time-consuming effort again, therefore also influenced portable driver's cab and on crawler crane, used.
Three, summary of the invention
But the purpose of this utility model provides a kind of driver's cab of crawler crane of automatically regulating height, after driver's cab rises, can make chaufeur when operation, enlarge the operation visual field, improved the safe reliability of work efficiency and operation, after driver's cab descends, in the time of also can satisfying with trailer transportation to the requirement of road limit for height.
The automatic lifting driver's cab of the utility model---crawler crane is to the fixedly improvement of driver's cab of existing crawler crane.The lifting employing of this driver's cab is installed jacking system and is realized that its jacking system is to be made of the parallel four-bar linkage that engine installation drives between driver's cab and vehicle frame.Parallel four-bar linkage constitutes with following bull stick is hinged with isometric and eternal parallel last bull stick with flat motion bar by deciding bar.The flat motion bar of driver's cab and parallel four-bar linkage is fixed, and it is decided bar and is connected with vehicle frame.Engine installation adopts hydraulic ram, and the following dwang of its piston rod and parallel four-bar linkage is fixed, and cylinder tube is by deciding the otic placode on the bar and deciding the bar lower end and fix.
The utility model adopts technique scheme, between driver's cab and vehicle frame jacking system has been installed.In construction operation, when needs are adjusted cab height, only need just can realize the automatic lifting of driver's cab that need not other people and help, the driver does not go out driver's cab can finish whole descending operations by the solenoid-driven engine installation.The utility model is simple in structure, and is reasonable in design, it is extremely convenient to operate, and has enlarged the operation visual field, improved the safe reliability of operation, and can satisfy trailer transportation and advance requirement to the road limit for height.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the lifting mechanism among Fig. 1;
Fig. 3 is that A among Fig. 1 is to revolved view;
Fig. 4 is an enforcement illustration of the present utility model.
Five, the specific embodiment
The automatic lifting driver's cab of the utility model as shown in Figure 1 and Figure 2,---crawler crane is installed jacking system and is realized between driver's cab 8 and vehicle frame 2.Jacking system drives parallel four-bar linkage by engine installation 5 and constitutes.Engine installation 5 adopts the hydraulic ram form, and its hydraulic ram is by the solenoid control of this crane hydraulic system.Parallel four-bar linkage is formed by deciding bar 4, flat motion bar 7, last dwang 9 and following dwang 6; Deciding bar 4 is the parts of 1 board-like body structure, last dwang 9 is 2, following dwang 6 is 1, flat motion bar 7 also is the parts of 1 board-like body structure, going up isometric and parallel being hinged on of the following dwang of dwang 9 and 16 for 2 erects deciding of placing and has so just constituted parallel four-bar linkage between bar 4 and the flat motion bar 7.Driver's cab 8 fixing welding or bolt together are at the facade place of the flat motion bar 7 of parallel four-bar linkage, and the bar 4 of deciding of parallel four-bar linkage is connected with vehicle frame 2 perpendicular to horizontal surface and its underpart.What engine installation 5 adopted is hydraulic ram, and the last hinge of hydraulic cylinder piston rod is hinged with following dwang 6 by bearing pin 12, and the bottom of its cylinder tube is used bearing pin 19 and decide bar 4 hinged by the otic placode of deciding on the bar 4.Accomplish to be parallel to ground rise or fall in order to ensure driver's cab, the top of deciding bar 4 of parallel four-bar linkage is connected on the vehicle frame 2 by control apparatus 10.Part 11 to 19 is the bearing pin that corresponding junction is used.As shown in Figure 3, control apparatus 10 adopts 2 V-arrangement length adjustment bars by top rod 20, adjusting lever 21, lower link 22 and jam nut 23 compositions, go up point of connection for 2 of its V-arrangement and be connected with the bar 4 of deciding of parallel four-bar linkage, point of connection is connected on the vehicle frame 2 under it.Two ends of the adjusting lever 21 of every length adjustment bar of control apparatus 10 in the middle of being positioned at are provided with the negative thread of different rotation directions, are connected the back with male end that top rod 20 and lower link 22 match respectively and lock with the jam nut 23 of corresponding rotation direction.That is to say that if lower link 22 upper ends are sinistral external thread, the lower end of adjusting lever 21 is a levogyrate inner thread just; Top rod 20 lower ends are the dextrorotation outside thread, and the upper end of the adjusting lever 21 of Pei Heing just is the dextrorotation negative thread with it.When needs are regulated, at first jam nut 23 is unclamped, rotate adjusting lever 21 then, because adjusting lever 21 2 end thread rotary orientation differences, make the thread end precession simultaneously or the back-out of top rod 20 and lower link 22, realized length adjustment, promptly realized to parallel four-bar linkage decide the vertical adjusting of bar 4, regulate the back that finishes and get final product with jam nut 23 lockings.What Fig. 4 provided is that the utility model is used for the enforcement illustration on the caterpillar telescopic boom crane.1 is telescopic boom among the figure, and 3 is track unit.
Descending operation of the present utility model is very convenient.When needs are regulated cab height, drive hydraulic ram with hydraulic oil, the upper end of hydraulic ram drives down, and dwang 6 rotates around bearing pin 13, foregoing parallel four-bar linkage motion principle, last dwang 9 is realized when bearing pin 14 rotates, drives flat motion bar 7 and realizes the driver's cab automatic lifting.This up-down mode, can reach more than 2 meters so adjustable height is also very big because the stroke of oil cylinder can be very big.
