Abstract
The invention discloses a chassis support structure for a wheel excavator. The chassis support structure is characterized by comprising a hydraulic telescopic arm hinged to a chassis, wherein a driving arm connected with the chassis is hinged to the middle of the hydraulic telescopic arm; a support seat is arranged at the free end of the hydraulic telescopic arm; the hydraulic telescopic arm is in a certain angle connection with the chassis. By adopting the technical scheme, the traveling and operating stability of the wheel excavator can be ensured and unnecessary personal and property loss is avoided.
Description
Technical field
The present invention relates to building operations excavator equipment field, especially relate to a kind of chassis support structure of wheel excavator.
Background technology
Excavator is a kind of multipurpose earthwork construction implement, mainly carry out excavation and the loading of the earthwork, the operations such as road pavement trench digging, be widely used in the place such as road construction, bridge construction, existing excavator is divided into wheel excavator and crawler-mounted excavator, also be proposed wheeled and that crawler type is dual-purpose excavator this year, for different action modes, different effects can be produced.
For wheel excavator, usually its occasion used is more smooth road surface, for the geographical environment of complexity, can produce many ill effects, but, although wheel excavator mobility strong, compared to crawler-mounted excavator, center of gravity is too high, on can generation is jolted, stability is not enough, especially under the road surface of complexity or the turning situation of wide-angle, often produces very large danger.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is the chassis support structure proposing a kind of wheel excavator.
Object of the present invention will be achieved by the following technical programs: a kind of chassis support structure of wheel excavator, this braced structures comprises the hydraulic telescopic arm be hinged with chassis, the middle part of described hydraulic telescopic arm is hinged with the actuating arm be connected with described chassis, supporting seat is provided with at the free end of described hydraulic telescopic arm, further, described hydraulic telescopic arm is connected at an angle with described chassis.
Preferably, the chassis support structure of above-mentioned a kind of wheel excavator, described hydraulic telescopic arm is divided into the first hydraulic telescopic arm and the second hydraulic telescopic arm, is provided with elastic buffer unit between described first hydraulic telescopic arm and described second hydraulic telescopic arm.
Preferably, the chassis support structure of above-mentioned a kind of wheel excavator, described first hydraulic telescopic arm and described second hydraulic telescopic arm are for being rotationally connected.
Outstanding effect of the present invention is: the chassis at wheel excavator is provided with braced structures, when cause owing to jolting center of gravity move forward or after move cause excavator easily to be toppled over time, braced structures can stablize its integral mechanical structure, can not cause the unnecessary person and property loss because of toppling over; By arranging buffer unit, the impact force that buffering gravity can be made to cause braced structures, improves its application life and security reliability; Rotary by hydraulic telescopic arm is set to, when meet with obstruction in normally advancing thing time, braced structures can be taken advantage of a situation folding, can not cause interference to the normal traveling of excavator.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, is easier to understand, grasp to make technical solution of the present invention.
Accompanying drawing explanation
Fig. 1 is the braced structures schematic diagram of this wheel excavator.
Detailed description of the invention
As shown in Figure 1, the chassis support structure of a kind of wheel excavator of the present embodiment, comprise the hydraulic telescopic arm 2 be hinged with chassis 1, the middle part of hydraulic telescopic arm 2 is hinged with the actuating arm 3 be connected with chassis 1, supporting seat 4 is provided with at the free end of hydraulic telescopic arm 2, and, hydraulic telescopic arm 2 is connected at an angle with chassis 1, supporting seat 4 is for touching with ground, reach the effect supporting excavator gravity, if this braced structures is arranged at the front of excavator, then hydraulic telescopic arm 2 is acute angle with the angle in the front on chassis 1, this kind of structure design can guarantee the support effect arrived very much, and coordinate the connection of actuating arm 3, can effectively stop toppling of excavator.
Concrete, hydraulic telescopic arm 2 is divided into the first hydraulic telescopic arm 201 and the second hydraulic telescopic arm 202, elastic buffer unit 5 is provided with between first hydraulic telescopic arm 201 and the second hydraulic telescopic arm 202, the pressure that excavator applies on the support structure can be eased by arranging elastic buffer unit 5, improve the application life of braced structures.
Concrete, first hydraulic telescopic arm 201 and the second hydraulic telescopic arm 202 are for being rotationally connected, when in the process normally travelled at excavator, if encounter obstruction below chassis 1, this is rotationally connected and can ensures that obstruction can smoothly by chassis 1, and the stop of hydraulic telescopic arm 2 can not be subject to, thus disturb normally advancing of excavator.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
