Description

Sweeper suction nozzle body changing direction lifting device

technical field

The utility model belongs to the technical field of cleaning vehicle accessories, in particular to a direction-changing lifting device for a suction nozzle body of a cleaning vehicle.

Background technique

The suction nozzle body of the sweeper is an important component of the sweeper. During the cleaning process of the sweeper, the hydraulic cylinder controls the suction nozzle body to descend, and the vacuum suction formed by the fan operation of the sweeper on the garbage bin sucks the garbage on the road into the garbage bin through the nozzle body and the connecting pipe. After the cleaning is completed, the hydraulic cylinder controls the suction nozzle body to rise, and the sweeper can drive quickly on the road.

Due to the high chassis and long wheelbase of the traditional sweeper, the installation space is large, and the nozzle body cylinder can be placed vertically without affecting the arrangement of other working parts. However, some small sweepers are limited by the chassis, the chassis height is low, and the wheelbase is short. After the sweeper is arranged on both sides of the vehicle body, there is no installation space for the suction nozzle body, which cannot meet the traditional hydraulic lifting cylinder arrangement.

Detailed ways

Below in conjunction with accompanying drawing and embodiment, further set forth the utility model. In the following detailed description, certain exemplary embodiments of the present invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments may be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

As shown in Figure 1, the lifting device for changing the direction of the suction nozzle body of the sweeping vehicle includes a mounting base 1, a lifting cylinder 2, a first guide wheel base 3, a second guide wheel base 4, a third guide wheel base 5 and a traction rope 6. The traction rope 6 is preferably a steel wire rope.

Referring to Fig. 1 and Fig. 3, during application, the mounting seat 1 is fixedly mounted on the side beam of the vehicle frame 7; the lifting cylinder 2 is horizontally arranged below the vehicle frame 7, which can effectively utilize the chassis space and facilitate the installation of the rest of the working parts; the cylinder end of the lifting cylinder 2 is connected to the mounting seat 1 through a fixed pin;

The first guide wheel seat 3 is fixedly installed on the other side longitudinal beam of the vehicle frame 7, the first guide wheel seat 3 is rotatably equipped with a first guide wheel 8; the second guide wheel seat 4 is fixedly installed on a crossbeam of the vehicle frame 7, and the second guide wheel seat 4 is rotatably equipped with a second guide wheel 9; the third guide wheel seat 5 is fixedly installed on another beam of the vehicle frame 7, and a third guide wheel 10 is rotatably installed on the third guide wheel seat 5;

The structure of each guide wheel seat is basically the same, the main difference is that the installation direction is different. With reference to Fig. 2, taking the second guide wheel seat 4 as an example, it includes a positioning plate 41, which is used for fixing with the vehicle frame. It is an L-shaped bending structure, which is convenient to install on the crossbeam or longitudinal beam of the vehicle frame; All of them should belong to the protection scope of the present utility model.

One end of the traction rope 6 is fixedly connected to the piston end of the lifting cylinder 2, and the other end of the traction rope 6 is fixedly connected to the suction nozzle body 11 after bypassing the first guide wheel 8, the second guide wheel 9 and the third guide wheel 10 in turn. The suction nozzle body 11 is located at the bottom of the chassis, and rollers are arranged on it to facilitate the collection of road garbage after the suction nozzle body falls. The outer peripheral surface of each guide wheel is respectively provided with a chute, when the suction nozzle body 11 is lifted and lowered, the traction rope 6 is stuck in the chute, and the guide wheel rotates with the movement of the traction rope. The limit bolt is mainly used to limit the position of the traction rope, so that the traction rope is stuck in the chute and will not fall out. The rotation planes of the first guide wheel 8 , the second guide wheel 9 and the third guide wheel 10 are preferably perpendicular to each other, so as to better meet the requirement of lifting and lowering the nozzle body.

Referring to Fig. 1, in order to prevent the lifting cylinder 2 from sagging due to the influence of the tension of the traction rope after the suction nozzle body 11 falls, an R-shaped oil cylinder fixing card 12 is installed on the crossbeam of the vehicle frame 7, and the lifting cylinder 2 is limited in the R-shaped oil cylinder fixing card 12, so that the hem of the lifting cylinder 2 can be avoided, so that the lifting of the suction nozzle body is reliable and will not fall after lifting.

The working principle of the utility model is as follows: the extension and contraction of the lifting cylinder 2 are controlled by the hydraulic valve group, and the traction rope 6 is driven to move. The traction rope 6 passes through the three guide wheel seats fixed on the main frame, and the force direction changes, thereby driving the suction nozzle body 11 located at the bottom of the chassis to lift or fall, so that the purpose of lifting and falling the suction nozzle body can be achieved in the smallest space.

The direction-changing lifting device makes it possible for the small vehicle to install the suction nozzle body at the bottom, so that the brushes on both sides of the vehicle are closer to the suction nozzle body arranged in the middle, so that the road cleaning effect of the vehicle is better. The lifting device can be adapted to lift the suction nozzle of any chassis, not only for vehicles with small wheelbase, but also for vehicles with large wheelbase. It has the characteristics of simple structure, convenient control, stability and reliability, and strong versatility.
