Description

Natural ventilation cab of sweeper

Technical Field

The utility model relates to a street sweeper technical field, concretely relates to street sweeper driver's cabin door.

Background

The sweeper is an integrated garbage sweeper combining sweeping and dust collection, has the advantages of high working efficiency, low cleaning cost, good cleaning effect, high safety performance, high economic return rate and the like, and is widely applied to the sweeping work of roads in various large, medium and small cities.

At present, a cab of an outdoor multifunctional sweeping machine powered by diesel oil is generally refitted on the appearances of a tricycle, a golf sightseeing vehicle, an agricultural vehicle and a loader cab, and the problems of large volume, large weight, uncoordinated appearance, improper window position, poor ventilation effect and the like generally exist.

Therefore, how to improve the cab of the existing sweeper so as to overcome the above problems is a problem to be solved urgently by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a quick-witted natural draft driver's cabin of sweeping floor that is pleasing to the eye, and daylighting is good, and the ventilation is smooth and easy, safe and reliable.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a quick-witted natural draft driver's cabin of sweeping floor, includes the driver's cabin frame, driver's cabin frame the place ahead is provided with preceding windshield, driver's cabin frame rear and below are enclosed construction, its characterized in that: cab doors are arranged on two sides of the cab frame, and a skylight is arranged above the cab frame;

the cab door comprises an upper frame, a lower frame, a connecting frame, upper tempered glass and lower tempered glass; the upper frame, the lower frame and the connecting frame form a half-frame structure, a door hinge is arranged on the front side of the half-frame structure, and a cab door is hinged to the cab frame through the door hinge; a first air spring is arranged between the half frame structure and the cab frame, first universal joints are arranged at two ends of the first air spring, and the first universal joints are respectively connected with the half frame structure and the cab frame; a door handle is arranged on the outer side of the connecting frame, a door lock is arranged on the inner side of the connecting frame, and the door handle and the door lock are integrally arranged; an elastic hinge and a hinge window catch are arranged between the upper tempered glass and the upper frame, the elastic hinge is positioned at the rear side, the hinge window catch is positioned at the front side, and the elastic hinge is matched with the hinge window catch, so that the upper tempered glass can have an opening degree at the front side of the upper frame; the lower toughened glass is fixed and covered on the outer side of the lower frame;

the skylight comprises a top plate, a second gas spring and a handle, the front end of the top plate is hinged to the cab frame, the second gas spring is arranged between the top plate and the cab frame and is positioned behind the top plate, second universal joints are arranged at two ends of the second gas spring and are respectively connected to the top plate and the cab frame, and the handle is fixedly arranged behind the inner side of the top plate; the second gas spring is always in a compressed state, the upward component force of the second gas spring is insufficient to jack the top plate when the skylight is closed, and the upward component force of the second gas spring is sufficient to support the top plate to keep an open state when the skylight is opened. When the skylight is closed, the included angle between the second gas spring and the horizontal plane is smaller, and under the condition of certain elastic force, the component force in the vertical direction is smaller, the component force is not enough to overcome the gravity of the top part to jack the top plate, meanwhile, the second gas spring has larger component force in the horizontal direction, the component force pushes the top plate backwards, and the front part of the top plate is hinged on the cab frame, namely, the front side and the rear side of the top plate have two opposite acting forces to keep the top plate in a closed state; when the top plate is pushed upwards manually, the separation of the second gas spring along the horizontal direction is reduced, and the component force along the vertical direction is increased, so that the upward component force of the second gas spring is enough to support the top plate and keep the top plate in an open state.

As an improvement, a rearview mirror is fixedly arranged on the upper frame. Because the cab door of the half-frame structure completely occupies two sides of the cab, and the cab frame is not provided with a position for installing the rearview mirror, the rearview mirror is suitable for being installed on the half-frame structure.

As an improvement, the connecting frame extends downwards to form a pressing plate, and the pressing plate is positioned on the outer side of the lower toughened glass. The pressing plate is pressed on the lower toughened glass to strengthen the fixation of the lower toughened glass and protect the upper edge of the lower toughened glass.

As an improvement, a warning lamp is detachably arranged on the top plate.

Preferably, the top plate extends downwards to form a cover plate, and the cover plate covers the cab frame. The cover plate extends downwards and covers the periphery of the cab frame to play a certain sealing role, and more importantly, the cover plate can prevent rainwater from entering the cab.

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

1. the scheme has the advantages of clear water caltrops and attractive and novel appearance, and meets the appearance design requirement of the urban sweeper.

2. The design of large tracts of land adoption toughened glass has the good advantage of daylighting, can improve the better visual angle of driver, is convenient for clean the development of work.

3. The doors, windows and skylights are designed with gas spring assistance, so that the damping sense is very sufficient, and the mechanical sense is good.

4. Due to the arrangement of the hinge type windows and the hinge type skylight, when the left window and the right window and the skylight are opened, the air circulation in the cab is good, air enters from the left hinge window and the right hinge window, and the skylight flows out, so that the ventilation in the cab is good.

5. The hinge type window can introduce fresh air as long as the opening amount is small, the trouble of installing the sliding rail is avoided, and meanwhile, the hinge type window has good sealing performance. It should be noted that the opening of the hinge window is arranged at the front side, so that when the sweeper travels, wind can naturally enter from the front side, the ventilation of the cab can be ensured when needed, and the skylight opening is arranged at the rear side, so that airflow can flow out from the rear side to form convection; in addition, the hinge window catch is positioned on the front side, so that a driver can conveniently open and close the window.

6. The professional door lock of driver's cabin and door handle integrated design, it is pleasing to the eye practical, small, and the switch door is convenient.
