Problems solved by technology

The cab of a traditional excavator is installed on the chassis through a rotating structure. Although the cab can rotate relative to the chassis during work, due to the complex working environment of the excavator, it is inevitable that the driver's line of sight will be blocked. situation, which will be unfavorable to the driver's operation

Embodiment 1

[0011] Such as figure 1 As shown, the structure of the excavator with a liftable cab in this embodiment is as follows: the bottom of the cab 1 of the excavator is connected to an auxiliary chassis 3 through several (more than three) hydraulic cylinders 2, and the auxiliary chassis 3 It is connected with the chassis 5 of the excavator through the rotating mechanism 4 .

[0012] During the construction process, when the driver's vision is blocked due to the insufficient height of the cab 1, the driver can control the hydraulic cylinder 2 to extend to increase the height of the cab 1, thereby widening the driver's field of vision; when driving After the condition that the operator's line of sight is blocked is eliminated, the driver can control the hydraulic cylinder 2 to retract, so that the height of the cab 1 is lowered, so as to lower the overall center of gravity and ensure the driving safety of the excavator.

[0013] The above-mentioned several hydraulic oil cylinders 2 a...

Abstract

The invention aims to provide an excavator with a lifting cab, which can reduce the blocking state of driver vision, thereby reducing the operation difficulty of a driver, and guaranteeing the construction operation safety. The excavator with the lifting cab provided by the invention comprises the following structures: the bottom of the cab of the excavator is connected with a sub chassis through a hydrocylinder, and the sub chassis is connected with a chassis of the excavator through a slewing mechanism. When the height of the cab is not enough so as to result in blocking the driver vision in a construction process, the driver can control the hydrocylinder to stretch out, the height of the cab is lifted, and the visual field of the driver is expanded and wider; and when the blocking condition of the driver vision is eliminated, the driver can control the hydrocylinder to retract, the height of the cab is reduced, the height of the whole barycenter is reduced, and the running security of the excavator is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment manufacturing, in particular to an excavator with a liftable cab. Background technique [0002] Excavator is a kind of important construction machinery, and its application is very extensive. The cab of a traditional excavator is installed on the chassis through a rotating structure. Although the cab can rotate relative to the chassis during work, due to the complex working environment of the excavator, it is inevitable that the driver's sight will be blocked. In such a situation, it will be unfavorable to the driver's operation. Contents of the invention [0003] The purpose of the present invention is to propose an excavator with a liftable cab to reduce the situation where the driver's sight is blocked, thereby reducing the difficulty of the driver's operation and ensuring the safety of construction work. [0004] The structure of the excavator with a liftable cab of...
