Abstract
The present invention relates to a kind of sweep angle constant sweep dish lifting gear.What mainly solve existing all kinds of sweeping machine sweeps dish in cleaning work process, because brush wearing and tearing shorten, sweep dish position height regulate decline after cause sweeping dish change of pitch angle, the problem of the frequent manual adjustment that needs to stop.This dish lifting gear of sweeping sweeping angle constant is made up of bearing, oil cylinder, linking arm, adjustable linking arm, mount pad and bearing pin, sweeps dish and is fixedly connected on mount pad.Described linking arm and adjustable linking arm two ends are formed while fixing space parallel-crank mechanism by the hole of bearing pin and mount pad and bearing is hinged, and promote above-mentioned space parallel-crank mechanism around the end generation rotary lifting movement that is fixedly hinged by the stretching motion of Cylinder Plunger, dish lifting is swept in drive, now, the inclination angle adjusted by mount pad can not be changed because of lifting position, keep sweeping dish to sweep angle constant.The initial tilt of mount pad regulates fixing by the bar shaped circular hole of mount pad.
Description
Art
The present invention relates to and a kind ofly sweep dish lifting gear for all kinds of sweeping machine, sweeping machine is the special-purpose vehicle for environmental sanitation cleaning, operation of keeping a public place clean.
Background technology
Sweeping dish is carry out the equipment that refuse sweeping collects in all kinds of sweeping machine cleaning work process, is rotated by fluid motor-driven.During sweeping machine cleaning work, this is swept dish and stretches out and drop to cleaning road surface, and carry out refuse sweeping and collect operation, cleaning work terminates, and sweeps dish and must promote a height and draw in, and sweeping machine could normal travel.In the sweeping disc for road sweeper course of work, because brush wearing and tearing shorten, be keep cleaning work effect, need discontinuity to continue to adjust the height and position of sweeping dish and to keep sweeping dish inclination angle constant.Sweep dish highly to regulate and can be driven by hydraulic jack, sweeping dish inclination angle needs artificial adjustment of stopping, and the operating efficiency of cleaning work personnel is affected, also has influence on the comfortableness of operation sweeping machine simultaneously.
Summary of the invention
In order to overcome shortcoming and the weak point of background technology, the invention provides a kind of sweep angle constant sweep dish lifting gear, this device weares and teares in brush, sweeping dish regulates in decline process gradually, sweep angle not change with sweeping dish high and low position, that has set up when remaining initial installation sweeps dish inclination angle, no longer stops artificial frequently to regulate in the dish inclination angle of sweeping of sweeping machine.
Technical scheme of the present invention is: a kind of sweep angle constant sweep dish lifting gear, comprise mount pad 1, adjustable linking arm 4, linking arm 5, oil cylinder 7, bearing 11, bearing pin 1, bearing pin 23, bearing pin 36, bearing pin 48, bearing pin 59, bearing pin 6 10, one end of described adjustable linking arm 4 is hinged with the hole of bearing 11 by bearing pin 48, the other end is hinged with the hole of mount pad 1 by bearing pin 1, one end of described linking arm 5 is by hinged with the hole of bearing 11 by bearing pin 59, the other end is hinged with the bar shaped circular hole of mount pad 1 by bearing pin 23, the tail end of described oil cylinder 7 and the hole of bearing 11 hinged, plunger end is hinged with the hole of linking arm 5 by bearing pin 36, described bearing 11 is fixed in the chassis frame of all kinds of sweeping machine, described mount pad 1 lower end is provided with the connecting hole for fixing all kinds of sweeping disc for road sweeper, it is characterized in that: described adjustable linking arm 4, linking arm 5 and bearing 11, mount pad 1 is hinged forms the spatial four-bar mechanism fixed on one side afterwards, by length adjustment and the locking formation space parallel-crank mechanism of adjustable linking arm 4, angle constant function is swept in realization, described spatial four-bar mechanism by the hole of linking arm 5 and oil cylinder 7 plunger end hinged, and the stretching motion being fixed in the oil cylinder 7 of bearing 11 promotes, rotary motion is produced around fixed edge, realize rising and the down maneuver of sweeping disc for road sweeper, described mount pad 1 is provided with bar shaped circular hole and sweeps sweeping angle size in order to regulate.
Originally the center line of bar shaped circular hole sweeping the mount pad 1 of dish lifting gear sweeping angle constant is a circular arc line, and this circular arc line with the center of bearing pin 1 for the centre of gyration, the radius of gyration is equal with the center to center distance of bearing pin 23 in plane of rotation with bearing pin 1.
Originally the linking arm 5 sweeping dish lifting gear sweeping angle constant is provided with the hole hinged with Cylinder Plunger end, and the center in this hole is not on the line at hinge hole center, linking arm 5 two ends.
The present invention has following beneficial effect: this device weares and teares in brush, sweeping dish regulates in decline process gradually, sweep angle not change with sweeping dish high and low position, that has set up when remaining initial installation sweeps dish inclination angle, cleaning effect is guaranteed, and sweeping machine no longer stops manually frequently to regulate and sweeps dish inclination angle.
Accompanying drawing explanation
Now the present invention is further described in conjunction with the accompanying drawings and embodiments.
Fig. 1 is the structural representation of lifting position of the present invention.
Fig. 2 is the structural representation of down position of the present invention.
In figure, mount pad 1, bearing pin 1, bearing pin 23, adjustable linking arm 4, linking arm 5, bearing pin 36, oil cylinder 7, bearing pin 48, bearing pin 59, bearing pin 6 10, bearing 11.
Detailed description of the invention
For accompanying drawing, embodiments of the invention are described further below:
Shown in figure, a kind of sweep angle constant sweep dish lifting gear, comprise mount pad 1, bearing pin 1, bearing pin 23, adjustable linking arm 4, linking arm 5, bearing pin 36, oil cylinder 7, bearing pin 48, bearing pin 59, bearing pin 6 10, bearing 11, one end of described adjustable linking arm 4 is hinged with the hole of bearing 11 by bearing pin 48, the other end is hinged with the hole of mount pad 1 by bearing pin 1, one end of described linking arm 5 is by hinged with the hole of bearing 11 by bearing pin 59, the other end is hinged with the bar shaped circular hole of mount pad 1 by bearing pin 23, the tail end of described oil cylinder 7 is hinged with the hole of bearing 11 by bearing pin 6 10, plunger end is hinged with the hole of linking arm 5 by bearing pin 36, described bearing 11 is fixed in the chassis frame of all kinds of sweeping machine, described mount pad 1 lower end is provided with the connecting hole for fixing all kinds of sweeping disc for road sweeper, described adjustable linking arm 4, linking arm 5 and bearing 11, mount pad 1 is hinged forms the spatial four-bar mechanism fixed on one side afterwards, the fixed edge of four-bar mechanism is formed with bearing 11 hinged end, the motion limit of four-bar mechanism is formed with mount pad 1 hinged end, by length adjustment and the locking formation space parallel-crank mechanism of adjustable linking arm 4, when adjustable linking arm 4, when linking arm 5 rotates generation rising and descending motion around fixed edge, brought into motion limit rises and declines, described motion limit remains parallel with fixed edge in rising with decline process, angle constant function is swept in realization, the linking arm 5 of described spatial four-bar mechanism is hinged by bearing pin 36 and oil cylinder 7 plunger end, and the stretching motion being fixed in the oil cylinder 7 of bearing 11 promotes, rotary motion is produced around fixed edge, realize rising and the down maneuver of sweeping disc for road sweeper, described mount pad 1 is provided with bar shaped circular hole, sweeping angle size is swept in order to regulate when sweeping dish and initially installing.
