Description

Multi-degree-of-freedom controllable cleaning disc brush

Technical Field

The utility model belongs to the cleaning machine field, concretely relates to controllable washing dish brush of multi freedom.

Background

Along with the aggravation of pollution such as haze, a series of products such as street lamp, glass curtain wall all need clean, burnisher on the current market can not satisfy actual needs, mainly cleans through the manual work at present, and artifical clean inefficiency is difficult to carry out cleaning operations at the high altitude because the restriction of manpower. If the mechanical operation needs to be realized, the cleaned object is not crushed, so that the tail end cleaning mechanism is required to have multiple degrees of freedom, the cleaning effect is also required to be ensured, proper pressure needs to be ensured, and higher requirements are provided for the controllability of the tail end cleaning mechanism.

Disclosure of Invention

An object of the utility model is to overcome the aforesaid not enough, provide a controllable washing dish brush of multi freedom, solved and mainly leaned on the manpower at present clean, clean inefficiency to can't carry out the high altitude cleaning operation problem, can realize that no dead angle is clean.

In order to achieve the purpose, the utility model discloses a base is provided with the base support on, be provided with a plurality of flexible pneumatic cylinders and an universal axis of rotation on the base support, and the common supporting disk brush support of all flexible pneumatic cylinder work bars and universal axis of rotation is provided with the dish brush on the dish brush support, and the stiff end of dish brush passes the universal axis of rotation of dish brush leg joint, and universal axis of rotation passes through motor drive.

The universal rotating shaft is arranged in the middle of the base support.

The telescopic hydraulic cylinder is arranged around the universal rotating shaft.

The number of the telescopic hydraulic cylinders is six, and the telescopic hydraulic cylinders are arranged at equal angles.

All the telescopic hydraulic cylinders are respectively connected with corresponding electro-hydraulic proportional valves, and all the electro-hydraulic proportional valves are controlled by the main controller.

The bottom of the base is provided with a bolt used for being connected with the bearing device.

Compared with the prior art, the utility model can clean stains at different angles by the brush disc through the telescopic amount of the plurality of telescopic hydraulic cylinders, and the connection relation between the base and the bearing device is not required to be changed, so that the device is convenient to adjust and rapid in response, the cleaned objects are prevented from being crushed in the cleaning process, different postures can be adjusted, different pressures are realized, and the cleaning effect is ensured; through the rotation of the universal rotating shaft of motor drive, drive the brush dish and rotate, when the dish brush gesture changes, still can transmit power, can not influence the work of dish brush, this device convenient to use, clean efficient, it is clean to have realized no dead angle.

Furthermore, the electro-hydraulic proportional valve is controlled by the main controller, so that the expansion and contraction of the hydraulic cylinder are adjusted, and the controllability of the tail end brush disc is greatly improved.

Furthermore, the device can be fixed at the tail end of the overhead working truck through a bolt, so that the overhead cleaning operation is realized.

the device comprises a disk brush support 1, a disk brush 2, a telescopic hydraulic cylinder 3, a base support 4, a base 5 and a universal transmission shaft 6.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1 and 2, the utility model discloses a

base

5, 5 bottoms of base are provided with the bolt that is used for being connected with the load-bearing device, be provided with base support 4 on the base 5, be provided with a plurality of flexible pneumatic cylinders 3 and a universal axis of rotation 6 on the base support 4, base support 4's middle part is arranged in to universal axis of rotation 6, flexible pneumatic cylinder 3 centers on universal axis of rotation 6 setting, 3 work bars of all flexible pneumatic cylinders and the 6 common supporting disk brush supports 1 of universal axis of rotation, be provided with the dish brush 2 on the dish brush support 1, the stiff end of dish brush 2 passes dish brush support 1 and connects universal axis of rotation 6, universal axis of rotation 6 passes through motor drive, corresponding electric liquid proportional valve is connected respectively to all flexible pneumatic cylinders 3, all electric liquid proportional valves.

Preferably, six telescopic hydraulic cylinders 3 are arranged at equal angles.

When the cleaning brush disc is installed, the base 5 is fixed at the tail end of the overhead working truck through bolts, the motor is installed inside the base 5, and an output shaft of the motor penetrates through a deep groove ball bearing inside the base 5 to be connected with the universal transmission shaft 6 to form a power output part of the cleaning brush disc.

The base support 4 is fixed to the base 5 by means of bolting, and the cylinder portions of the six telescopic hydraulic cylinders 3 are fixed to the support base 4 by means of bolting.

The other end telescopic parts of the six telescopic hydraulic cylinders 3 are hinged to the disc brush support 1 through pin shafts to form six degrees of freedom, the hinged parts of the six parts are respectively welded to the disc brush support 1, and the angle sensor is installed at the bottom of the disc brush support 1.

The disc brush 2 penetrates through a deep groove ball bearing inside the disc brush support 1 to be connected with the universal transmission shaft 6, the deep groove ball bearing is fixed through a bearing end cover, and the bearing end cover is connected to the disc brush support 1 through a bolt. The block diagram is shown in fig. 2.

The universal drive shaft 6 consists of three sections: first, a shaft section connected to an output shaft of the motor; second, the shaft section between the disc brush holder 1 and the base holder 4, and third, the shaft section to which the disc brush 2 is directly connected. The three sections are connected by two hinges, and the structure is shown in figure 3.

When the device is used, the device is installed at the tail end of an aerial work vehicle, when an aerial work arm is unfolded, the disc brush 2 is conveyed to a certain position, and a control command is input into the controller, so that the controller controls the six electro-hydraulic proportional valves to drive the six telescopic hydraulic cylinders 3, and different angle positions are realized; after adjustment, if the preset adjustment precision is not met, the electro-hydraulic proportional valve is adjusted again, and the six telescopic hydraulic cylinders 3 are controlled to perform adjustment. Otherwise, no action is necessary.

After the position adjustment is completed, the motor is started to drive the universal transmission shaft 6 to rotate, so that the disc brush 2 is driven to rotate for cleaning. When the six telescopic hydraulic cylinders 3 are adjusted, the disc brush support 1 and the disc brush 2 can rotate, and at the moment, the two cross hinge points of the universal transmission shaft 6 can also rotate to a certain extent, but normal transmission can still be achieved.
