Abstract
The utility model discloses a kind of Telescopic rod structures of overturning-preventing, including column, column is equipped with platform, platform is equipped with mounting bracket, first track and the second track, first track and the second track are located at the left and right sides of mounting bracket respectively, on first track clump weight is connected with by several first sliding blocks, clump weight is connected with mounting bracket by the first oil cylinder, on second track operating trolley is connected with by several idler wheels, it is connected between operating trolley and mounting bracket by the second oil cylinder, the weight of the clump weight is N times of operating trolley, first oil cylinder and the second oil cylinder simultaneous retractable, by lever principle, the displacement distance of clump weight is the 1/N of the displacement distance of operating trolley, it can keep whole machine balancing state.The utility model is designed reasonably, simple in structure, clump weight and operating trolley are mobile simultaneously, by lever principle, keep overall structure balance, prevent that high-altitude operation vehicle is caused to topple over.
Description
Technical field
The utility model is related to high-altitude operation vehicle technical field, more particularly to a kind of Telescopic rod structure of overturning-preventing.
Background technology
The vertical lifting of high-altitude operation vehicle generally relies on hydraulic-driven or hoist engine rope is promoted, and is promoted to the work behind high-altitude
The movement in the horizontal direction of industry platform generally relies on telescopic arm completion.Its telescopic arm structure of existing high-altitude operation vehicle is generally one
End is fixed, and the cross bar that one end can extend paragraph by paragraph, job platform is located at the front end of cross bar, during cross bar constantly extends,
Due to lever principle, the torque of job platform is increasing, this is easy to cause entire high-altitude operation vehicle disequilibrium, causes high-altitude
Operation Van is toppled over.
Utility model content
The utility model is above-mentioned in order to overcome the shortcomings of, provides a kind of Telescopic rod structure of overturning-preventing, including column, stands
Column is equipped with platform, and platform is equipped with mounting bracket, the first track and the second track, and the first track and the second track are located at peace respectively
The left and right sides shelved is connected with clump weight, clump weight and mounting bracket by several first sliding blocks on the first track and passes through the first oil
Cylinder connects, and operating trolley is connected with by several idler wheels on the second track, is connected between operating trolley and mounting bracket by the second oil cylinder
It connects, the weight of the clump weight is N times of operating trolley, the first oil cylinder and the second oil cylinder simultaneous retractable, by lever principle, counterweight
The displacement distance of block is the 1/N of the displacement distance of operating trolley, can keep whole machine balancing state.
Preferably, the mounting bracket is equipped with control device, and the control device controls the first oil cylinder and the second oil cylinder to stretch
Go out or retraction piston rod.
Preferably, first track is shorter than the second track.
Preferably, the column is located at the position that left side is biased to below platform.
The beneficial effects of the utility model are：The utility model is designed reasonably, simple in structure, clump weight and operating trolley are same
Shi Yidong by lever principle, keeps overall structure balance, prevents that high-altitude operation vehicle is caused to topple over.
Description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
As shown in Figure 1, the utility model is a kind of Telescopic rod structure of overturning-preventing, including column 1, column 1 is equipped with flat
Platform 2, platform 2 are equipped with mounting bracket 3, the first track 4 and the second track 5, and the first track 4 and the second track 5 are located at installation respectively
The left and right sides of frame 3 is connected with clump weight 7, clump weight 7 and mounting bracket 3 by first track 4 by several first sliding blocks 6
One oil cylinder 8 connects, and operating trolley 10 is connected with by several idler wheels 9 on the second track 5, leads between operating trolley 10 and mounting bracket 3
It crosses the second oil cylinder 11 to connect, the weight of the clump weight 7 is N times of operating trolley 10, and the first oil cylinder 8 and the second oil cylinder 11 are simultaneously
Flexible, by lever principle, the displacement distance of clump weight 7 is the 1/N of the displacement distance of operating trolley 10, can keep whole machine balancing shape
State.
The mounting bracket 3 is equipped with control device 12, and the control device 12 controls the first oil cylinder 8 and the second oil cylinder 11 to stretch
Go out or retraction piston rod.
First track 4 is shorter than the second track 5.
The column 1 is located at the position that left side is biased in 2 lower section of platform.
The utility model is designed reasonably, simple in structure, clump weight and operating trolley are mobile simultaneously, by lever principle, protect
Overall structure balance is held, prevents that high-altitude operation vehicle is caused to topple over.
Above-mentioned foundation the utility model is enlightenment, and by above-mentioned description, relevant staff completely can be not
In the range of deviateing this item utility model technological thought, various changes and amendments are carried out.This item utility model it is technical
Range is not limited to the content on specification, it is necessary to determine its technical scope according to right.
