Description

Compact aerial work platform

【Technical field】

The utility model relates to the field of engineering machinery, in particular to a kind of high-altitude operation equipment, and more particularly relates to a compact type high-altitude operation platform.

【Background technique】

Aerial work platform is an advanced aerial work machine, which has flexible mobility and wider activity space, so it can greatly improve the work efficiency, safety and comfort of aerial construction personnel, and reduce labor intensity.

However, since the aerial work platform needs to have sufficient horizontal and vertical working ranges, the size of the telescopic transmission assembly of the aerial work platform becomes very large. Therefore, correspondingly, when the aerial work platform is out of service and the corresponding telescopic transmission assembly is to be stored, the telescopic transmission assembly often cannot be fully folded, which results in a large space occupied by the entire aerial work platform.

The engine, fuel tank, reducer and other components of the existing aerial work platform are all installed on the turntable, so the length of the entire aerial work platform is longer and the height is higher, which brings certain inconvenience to the movement and parking of the aerial work platform place.

Therefore, it is necessary to provide an improved aerial work platform, which becomes compact after being stored, thereby reducing the occupied storage space, and is short in length and low in height, and its overall structure is optimized to overcome the above-mentioned disadvantages of the prior art. Disadvantages and deficiencies.

【Content of utility model】

The purpose of the utility model is to provide a compact aerial work platform, which has a simple structure, and the space occupied by the whole machine after the telescopic transmission assembly is stored is very small, so it further increases the aesthetics of the whole machine to a certain extent, and The whole machine is short in length and low in height, and the overall structure has been optimized.

To achieve this purpose, the utility model adopts the following technical solutions:

A compact high-altitude work platform includes a car body, a turntable rotatably arranged on the car body, a telescopic transmission assembly rotatably arranged in the turntable, and an operating table arranged at the end of the telescopic transmission assembly. The turntable is a hollow structure, which includes a bottom plate extending along the longitudinal direction of the car body and side plates bent from both sides of the bottom plate in the width direction of the car body. Between the two side plates and the bottom plate A space for accommodating the telescopic transmission assembly is defined between them, and no parts are installed on both sides of the turntable, and an engine, a fuel tank, and a reducer are arranged on the chassis of the car body.

Preferably, the telescopic transmission assembly includes a parallelogram linkage mechanism rotatably arranged in the space jointly defined between the two side plates and the bottom plate of the turntable, connected with the parallelogram linkage mechanism by means of a connecting seat A hinged telescopic main arm and a small arm rotatably arranged at the end of the telescopic main arm.

Preferably, the above-mentioned operating table is installed at the end of the forearm. A cylinder is arranged between the parallelogram linkage mechanism and the telescopic main arm. Further preferably, a counterweight is provided at the rear end of the turntable.

Compared with the prior art, the utility model has the following advantages:

The parallelogram linkage mechanism of the telescopic transmission assembly will be folded and accommodated in the space jointly defined between the two side plates and the bottom plate of the turntable, thus at least avoiding that the parallelogram linkage mechanism exclusively occupies a certain space, Instead, it is stored in the turntable. Overall, the floor space of the whole machine is reduced, and since the parallelogram linkage mechanism is hidden inside the turntable and is covered by the side plate, it is almost impossible to see the parallelogram linkage mechanism from the outside, which improves the overall machine performance. aesthetics.

【detailed description】

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Referring to Figures 1-5, according to an embodiment of the present invention, a compact aerial work platform 100 includes a car body 200, a turntable 300 rotatably arranged on the car body 200, and a telescopic The transmission assembly 102 and the console 103 arranged at the end of the telescopic transmission assembly 102 .

Here, the turntable 300 is a hollow structure, which includes a bottom plate 304 extending along the longitudinal direction of the vehicle body 200 and side plates 302 bent from both sides of the bottom plate 304 in the width direction of the vehicle body 200 . The turntable 300 formed by the two side plates 302 and the bottom plate 304 has a U-shaped cross section. Moreover, a space is defined between the two side plates 302 and the bottom plate 304, which is used to store and accommodate the partial components of the telescopic transmission assembly 102 after the aerial work platform 100 is completed, so as to reduce the size of the telescopic transmission assembly 102. The storage space occupied thereby reduces the volume occupied by the whole machine. At the same time, it further increases the aesthetics of the whole machine.

Preferably, the telescopic transmission assembly 102 includes a parallelogram linkage mechanism 1022 rotatably disposed in the space jointly defined between the two side plates 302 and the bottom plate 304 of the turntable 300 , connected with the The telescopic main arm 1022 articulated by the parallelogram linkage mechanism 1022 and the small arm 1021 rotatably arranged at the end of the telescopic main arm 1022 . The end of the forearm 1021 is installed with the console 103 .

In addition, a cylinder 1028 is provided between the parallelogram linkage mechanism 1022 and the telescopic main arm 1022 . Therefore, when the cylinder 1028 works, the telescopic main arm 1022 can be urged to rotate at a certain angle relative to the parallelogram linkage mechanism 1022 and extend out.

Preferably, a counterweight 400 is provided at the rear end of the turntable 300 . Due to the presence of the counterweight 400, when the telescopic transmission assembly 102 is stretched out for operation, the weight of the entire telescopic transmission assembly 102, the operating platform 103, and the operators standing in the operating platform 103 is carried by the counterweight. The 400° balance prevents the whole machine from overturning forward and ensures the safety of the whole machine.

After the operation of the compact aerial work platform 100 is completed, the entire telescopic transmission assembly 102 needs to be shrunk as much as possible so as to reduce the occupied space. Here, the parallelogram linkage mechanism 1022 of the telescopic transmission assembly 102 will be folded and accommodated in the space jointly defined between the two side plates 302 and the bottom plate 304 of the turntable 300, thus at least avoiding parallelogram linkage. The rod mechanism 1022 exclusively occupies a certain space, but is housed in the turntable 300 . Therefore, the floor space of the whole machine is generally reduced, and since the parallelogram linkage mechanism 1022 is hidden inside the turntable 300 and is covered by the side plate 302, it is almost impossible to see the parallelogram linkage mechanism 1022 from the outside. This improves the aesthetics of the whole machine.

At the same time, it should be noted that there are no installations on both sides of the turntable (except for the installation of strobe lights and power sockets). on the chassis of the vehicle body 200 . At the same time, the utility model optimizes the design of the whole machine structure, so that the length of the whole aerial work platform is shorter and the height is lower.

Therefore, the above-mentioned embodiment is a preferred implementation mode of the present utility model, but not only limited by the above-mentioned embodiment, any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present utility model , should be equivalent replacement methods, and are all included in the protection scope of the present utility model.
