Abstract
The utility model discloses a quick changing structure for side brush handles of a sweeper. The quick changing structure for the side brush handles of the sweeper comprises a side brush motor and a side brush handle, wherein a motor shaft of the side brush motor is detachably connected with a shaft sleeve connecting block fixedly; a flange is formed on the shaft sleeve connecting block; a short pin is arranged on a bottom end surface of the flange; a shaft hole and a hole site corresponding to the short pin are formed in the side brush handle; the shaft sleeve connecting block positioned below the flange penetrates in the shaft hole and then is locked by a nut; and the short pin extends in the hole site. By using the quick changing structure, torque is transmitted safely and reliably; the quick changing structure cannot loose or slip even if the quick changing structure is used for a long time; and when the side brush handles are changed, a corresponding special tool is not required, the side brush handles are assembled or disassembled quite conveniently, timeliness on changing of the side brush handles is high, and the disassembling time is short.
Description
Technical field
The utility model relates to road sweeper, is the limit brush handle fast replacing structure of road sweeper specifically.
Background technology
Limit brush handle on road sweeper is a kind of conical sleeve shape brush, and the limit brush handle that is arranged on road sweeper two bottom sides is mainly used in cleaning edge, roadside.Because the limit brush handle rotating in process of sweeping the floor directly contacts with ground, bristle has normal wearing and tearing, so limit brush handle is the consumptive material on road sweeper, need to often change, and the limit brush handle of replacing inefficacy becomes one of General Maintenance maintenance task.Road sweeper side brush device is that the mode that adopts frictional force to clamp is carried out transmitting torque mostly on the market, easily there is the skidding that gets loose in time length, and, the limit brush handle that is positioned at road sweeper bottom is liftoff nearer, and operating space is narrow, and adding dismounting needs corresponding special tool conventionally, so change the limit brush handle having lost efficacy, need assistant director to dismantle with special instrument, replacing promptness is poor, and unloading process is long, and work efficiency is poor.Therefore the limit brush handle syndeton in conventional art is further improved and optimizes.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of limit brush handle quick replacement device of road sweeper, has moment of torsion and transmits feature safe and reliable, easy accessibility.
The utility model solves the technical scheme that its technical problem adopts:
The limit brush handle fast replacing structure of road sweeper, comprise limit brush motor and limit brush handle, on the motor shaft of described limit brush motor, removably connect and be fixed with axle sleeve contiguous block, on described axle sleeve contiguous block, be formed with a flange, on the bottom face of described flange, be provided with short pin, on the brush handle of described limit, be formed with an axis hole and the hole position corresponding with described short pin, the axle sleeve contiguous block that is positioned at flange below through after described axis hole by nut check, described short pin extend into described Kong Weizhong.
Improvement as technique scheme, on described axle sleeve contiguous block, be formed with centre bore, the motor shaft of described limit brush motor stretches in this centre bore, on this motor shaft and described centre bore, be formed with corresponding keyway, in keyway, be shelved with key, on the sidewall of described axle sleeve contiguous block, be provided with the thread jack that is communicated with described keyway, in described thread jack, be connected with for holding out against the lock-screw of key.
As the further improvement of technique scheme, the number of described short pin is four, and is circumferentially distributed on described flange.
The beneficial effects of the utility model are: the utility model that adopts said structure, motor shaft is connected by axle sleeve contiguous block with limit brush handle, utilize the short pin on axle sleeve contiguous block to carry out moment of torsion transmission, moment of torsion transmits safe and reliable, after the time is long, also there will not be the skidding that gets loose; Utilize flange and coordinating of nut that axle sleeve contiguous block is arranged on the brush handle of limit, axle sleeve contiguous block removably connects and is arranged on motor shaft, so when needs are more changed sides brush handle, after only need unclamping nut, directly extract limit brush handle out, and do not need corresponding special tool, dismounting is extremely convenient, and the replacing promptness of limit brush handle is good, and the take-down time is short.The features such as the utility model also has simple and reasonable compactness, and implementation cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is decomposing schematic representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to Fig. 1 ~ Fig. 2, the limit brush handle fast replacing structure of road sweeper of the present utility model, comprise limit brush motor 1 and limit brush handle 2, on the motor shaft 11 of described limit brush motor 1, removably connect and be fixed with axle sleeve contiguous block 3, on described axle sleeve contiguous block 3, be formed with a flange 31, on the bottom face of described flange 31, be provided with short pin 32, on described limit brush handle 2, be formed with an axis hole 21 and the hole position 22 corresponding with described short pin 32, the axle sleeve contiguous block 31 that is positioned at flange 31 belows is locked by nut 4 through after described axis hole 21, and described short pin 32 extend in position, described hole 22.In this structure, motor shaft 11 is connected by axle sleeve contiguous block 3 with limit brush handle 2, utilizes the short pin 32 on axle sleeve contiguous block 3 to carry out moment of torsion transmission, and moment of torsion transmits safe and reliable, after the time is long, also there will not be the skidding that gets loose; Utilize flange 31 and coordinating of nut 4 that axle sleeve contiguous block 3 is arranged on limit brush handle 2, axle sleeve contiguous block 3 removably connects and is arranged on motor shaft 11, so when needs are more changed sides brush handle 2, so when needs are more changed sides brush handle 2, only need unclamp the rear direct extraction of nut 4 limit brush handle 2, and not need corresponding special tool, dismounting is extremely convenient, the replacing promptness of limit brush handle is good, and the take-down time is short.
In the present embodiment, the removably connect structure of axle sleeve contiguous block 3 on motor shaft 11 can adopt following structure: on described axle sleeve contiguous block 3, be formed with centre bore 33, the motor shaft 11 of described limit brush motor 1 stretches in this centre bore 33, on this motor shaft 11 and described centre bore 33, be formed with corresponding keyway 5, in keyway 5, be shelved with key 7, on the sidewall of described axle sleeve contiguous block 3, be provided with the thread jack 34 that is communicated with described keyway 5, in described thread jack 34, be connected with for holding out against the lock-screw 6 of key 7.Certainly, also can adopt other known structures that removably connects.
In the present embodiment, more steadily reliable for guaranteeing moment of torsion transmission, the number of described short pin 32 is four, and is circumferentially distributed on described flange 31.
The above, be better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
