Background technique

With the emergence of more and more skyscrapers in modern big cities, and the increasingly diverse styles of building complexes, higher requirements are put forward for window cleaning machines for cleaning the exterior walls and facades of buildings. Commonly used window cleaning machines have been Gradually unable to meet the cleaning and use requirements of some special buildings.

In the past, when window cleaning machines solved the cleaning problem of large concave curtain wall buildings, they always increased the size and structure of the platform of the window cleaning machine, which made the overall weight of the big arm of the window cleaning machine very heavy. Although it can meet part of the use requirements, its cost is high. Moreover, the requirements for the bearing capacity of the building are very high, and the cleaning work of some large concave curtain wall facades with parapets still cannot be completed, which has become a dead corner for building cleaning.

Utility model content

In view of the above problems, the purpose of this utility model is to provide an excavator-type window cleaning machine, so that the window cleaning machine can clean the facade of a large concave building curtain wall, especially the facade of a large concave curtain wall with a parapet, and complete the building. Cleaning and maintenance of facades.

In order to achieve the above object, the technical scheme of the utility model is as follows:

Excavator type window cleaning machine, including: operating mechanism, chassis, slewing mechanism, lifting mechanism, column, boom, folding arm swing, folding arm support, hydraulic push cylinder, folding arm, pull rod, lower arm head and platform . The underframe is connected to the running mechanism, the upper part of the underframe is connected to the slewing mechanism, the lifting mechanism is connected to the support base of the column, the column is connected to the slewing mechanism, and the top of the column is connected to the middle of the boom , the swing arm is connected to one end of the boom, the swing arm support is connected to the swing arm, one end of the hydraulic push cylinder is connected to the swing arm support, and the other end is connected to the front pin shaft of the fold arm, and the fold arm The rear pin is connected with the lower arm head, and the front pin shaft and the rear pin shaft of the pull rod are respectively connected with the folding arm support and the lower arm head. The boom formed by the folding arm and the tie rod can swing around the hinge point on the support of the folding arm.

The window cleaning machine with the structure of the utility model uses the thrust of the hydraulic cylinder to make the folding arm and the pull rod swing around the front fulcrum. When the hydraulic push cylinder is fully retracted, the elevation angle of the folding arm is the minimum angle, and the folding arm is completely vertical at this time; when the hydraulic push cylinder is fully extended, the elevation angle of the folding arm is the maximum angle, which can reach 90o. The head of the folding arm reaches the highest position, and the platform reaches the top, which can cross the lower parapet wall to complete the cleaning of the facade of large concave buildings with parapet walls. When the machine is stopped, the folding arm is lifted up 90o, and it can be parked completely horizontally, reducing the size of the equipment when it is stopped.

In a preferred solution of the present invention, the guide pulleys set in the folding arm to guide the wire rope are arranged on the pin shafts before and after the folding arm, so that the length of the wire rope does not change when the folding arm is pitching up, that is, the distance between the platform and the lower arm head The relative position does not change, so that the whole device can work perfectly during the folding and pitching process.

In another preferred solution of the present utility model, the front pin shaft and the rear pin shaft of the folding arm and the four rotating shafts of the front pin shaft and the rear pin shaft of the pull rod form a parallelogram, and the four hinge points are driven by hydraulic push cylinders, so that The rocking bar formed by the front shaft of the pull bar and the front shaft of the folding arm always keeps a certain relationship and rotates in the plane.

In another preferred solution of the present utility model, the design length of the pull rod is exactly the same as the length of the folding arm, and it only bears tension in terms of force, so that the lower arm head is always kept in balance.

Detailed ways

In order to make the technical means and implementation of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments.

Referring to Fig. 1 and Fig. 2, the utility model includes: operating mechanism 1, underframe 2, slewing mechanism 3, lifting mechanism 4, column 5, big arm 6, folding arm rotation 7, folding arm support 8, hydraulic push cylinder 9 , folding arm 10, pull bar 11, lower arm head 12, platform 13. In order to facilitate the movement of the whole device, the running mechanism 1 is generally placed on a special track, the lower part of the chassis 2 is connected to the running mechanism 1, the slewing mechanism 3 is fixedly connected to the chassis 2 by conventional means such as bolts, and the lifting mechanism 4 is fixedly connected to the column 5, the column 5 is connected to the rotary mechanism 3 by conventional means such as bolts, the top of the column 5 is connected to the middle of the boom 6, and the lower end of the folding arm 7 can be connected to one end of the boom 6 by bolts, etc. Bolts etc. are connected with the folding arm support 8, the two ends of the hydraulic push cylinder 9 are respectively connected with the folding arm support 8 and the front pin shaft of the folding arm 10, the rear pin shaft of the folding arm 10 is connected with the lower arm head 12, and the front pin shaft of the pull rod 11 is connected with the folding arm The support 8 is connected, the rear pin shaft of the pull rod 11 is connected with the lower arm head 12, the boom formed by the folding arm 10 and the pull rod 11 can swing smoothly around the upper hinge point of the folding arm support 8, and the hydraulic push cylinder 9 is the folding arm 10 and the pull rod 11 forms the driving device for the boom swing, the platform 13 is suspended below the lower arm head 12, and is connected to the hoisting mechanism 4 through the steel wire rope and the guide pulley block, and the lifting mechanism 4 can control the lifting of the platform 13; The pulley block guiding the wire rope in the arm 10 can be directly arranged on the front and rear pin shafts of the folding arm 10, so that the length of the wire rope does not change during the pitching process of the folding arm, that is, the relative position between the platform and the lower arm head does not change, and the bending arm is avoided. Start the hoisting mechanism during the pitching process, so that the whole equipment can work smoothly during the folding arm pitching process.
