Abstract
The utility model discloses an engineering machinery operating instrument platform, and belongs to the technical field of engineering machinery. The engineering machinery operating instrument platform comprises a shell body, a steering wheel, a fixed support, a rotary support, a rotary shaft, a locking device, and a rotary sleeve, wherein the fixed support is fixed on a base plate of a cab, the rotary support is connected on the fixed support through the rotary sleeve, the steering wheel is fixed on the rotary support, the locking device is installed on the fixed support and the rotary support, the upper end of the rotary shaft is fixed on the upper portion of the rotary support, the lower end of the rotary shaft stretches out and draws back freely and is connected with a bearing through a cardan joint in a movable mode, and the bearing is fixed on the fixed support. The engineering machinery operating instrument platform has the advantages that the length of the cardan joint can be adjusted freely, so that the phenomenon that the rotary shaft is clamped is overcome, and at the same time, requirements for installing precision of the welding of the support and connecting positions of the rotary shaft are lowered. During rotating front and back in a slant mode, the engineering machinery operating instrument platform uses the rotary sleeve as a rotating center, small in rotating point, and low in failure rate. Due to the fact that an upper shell body is connected with a lower shell body through a rubber sleeve, installing is convenient and fast, and maintaining is convenient. Due to the fact that the shell body is made of ABS materials, the engineering machinery operating instrument platform is free of pollution, and capable of being recycled and reused.
Description
Technical field
The utility model relates to a kind of operation instrument desk, specifically is a kind of work machine operation instrument desk, belongs to technical field of engineering machinery.
Background technology
At present, work machine operation instrument desk height is fixed, and just its turning cylinder length is certain value, can't regulate, like this to framing member welding and the accuracy requirement of turning cylinder length than higher.Need special welding tooling, and the requirement of the assembly precision of turning cylinder point of connection position is high, if welding or assembling do not reach correspondingly requirement, can cause the position of point of connection inaccurate, turning cylinder occurs and rotate stuck phenomenon, welding operation simultaneously is loaded down with trivial details, and tooling cost improves.
Verting in the front and back of present work machine operation instrument desk is to rotate by planar linkage mechanism, adds the angle that a slider-crank mechanism restriction is verted, complex structure, easy break-down.
Work machine operation instrument desk enclosure material is a carbon steel, need be welded into cubic type, need surface treatment, and whole production process is many, and not only consuming time but also cost increases, and can't utilize again.
The utility model content
At the problem that above-mentioned prior art exists, the utility model provides a kind of work machine operation instrument desk, but its turning cylinder length free adjustment and stuck phenomenon can not occur; It is by verting before and after the center of turn, and is simple in structure, and fault rate reduces.
To achieve these goals, a kind of work machine operation instrument desk of the present utility model, comprise housing, bearing circle, fixed support, swinging mounting, turning cylinder, latching device and pivoted housing, fixed support is fixed on the operator's compartment base plate, swinging mounting is connected on the fixed support by pivoted housing, bearing circle is fixed on the swinging mounting, latching device is installed on fixed support and the swinging mounting, the turning cylinder upper end is fixed on swinging mounting top, freely stretch and flexibly connect by universal-joint and bearing in the turning cylinder lower end, bearing fixing is on fixed support.
Further, housing comprises top shell, upper shell and lower house, and the top shell is arranged on the place ahead of bearing circle, and upper shell links to each other with lower house by rubber coating.
Preferably, housing adopts ABS plastic.
Principle of work: at first latching device is unclamped, regulate pivoted housing according to need of work, verting before and after the operation instrument desk of the present utility model is center of turn with the pivoted housing just, when being transferred to suitable angle latching device is fixed, and then the length of turning cylinder also changes thereupon; Turning cylinder is movably connected on the bearing by universal-joint, because turning cylinder length is telescopic, along with the rotation of bearing circle just drives the rotation of turning cylinder, then the length of turning cylinder changes, residing position of universal-joint and pivoted housing be not on same horizontal surface, and turning cylinder just can not be stuck.
Beneficial effect is: 1) but turning cylinder length free adjustment then overcomes the turning cylinder stuck phenomenon, the assembly precision to the welding of support and turning cylinder point of connection position requires to reduce simultaneously.Verting in front and back is center of turn with the pivoted housing only, and run-on point is few, and fault rate reduces.2) housing comprises top shell, upper shell and lower house, and upper shell links to each other with lower house by rubber coating, and it is convenient, easy to maintenance to install.3) housing adopts the ABS material, and is pollution-free, recyclable utilization again.
