Abstract

The invention discloses a wall surface cleaning machine and a wall surface suction and separation device. When the working program is started, the sliding rail extends forwards under the action of the hydraulic cylinder, the hollow telescopic arm connected with the sliding rail and the sucker at the front end of the telescopic arm extend forwards and extend forwards until the sucker is in contact and attraction with the wall surface, when a projection is formed on the wall surface in the cleaning process, the program gives an instruction, the sucker with the telescopic arm and the front end is retracted and retracted when the hydraulic cylinder is retracted, and when the cleaning equipment avoids the projection, the program instructs the hydraulic cylinder to extend forwards repeatedly.

Description

Wall grabbing device of automatic wall surface cleaning equipment

The technical field is as follows:

the invention relates to an automatic wall surface cleaning machine which is always in close contact with a wall surface during cleaning. When the wall surface meets the projection, under the control of the program, the automatic wall surface cleaning device is completed by quickly separating and hiding the sucking disc in front of the wall grabbing device from the wall surface and then sucking the sucking disc.

Background art:

the most common devices which are tightly attached to the glass wall surface in high-rise cleaning equipment reported by news or seen by the individuals from patent retrieval at present are fixed negative pressure suckers, and the suckers have the biggest problem; when a cleaning platform attached to the cleaning platform runs up and down and meets a projection on the wall surface, the cleaning platform is difficult to timely separate, so that the cleaning platform must stop waiting and complete separation from the wall surface through a series of actions, avoids closing again, and reduces the working efficiency of the cleaning equipment.

The invention content is as follows:

the invention mainly comprises installing a plurality of sucking discs which can freely stretch and retract under the control of a program on a proper position on a hanging basket of cleaning equipment to complete the suction and the separation with a wall surface. The main technical characteristics are that; firstly, mounting columns are welded in the middle of the hanging basket before and after proper displacement, a pair of slide rails is symmetrically arranged on the mounting columns at the right and left sides of the mounting columns, and hydraulic cylinder limiting nails are arranged on the mounting columns between the two slide rails. Then a hollow telescopic arm with a certain length is made of stainless steel, a short slide rail is fixedly arranged at a proper position in the telescopic arm, a baffle plate is welded at the tail end of the slide rail, a thin shaft is welded at a proper position of the baffle plate, a baffle plate with a hole in the middle for the thin shaft to pass through is fixedly arranged at a proper position on a movable rail of the slide rail, a section of spring is respectively arranged in front of and behind the baffle plate, the spring is locked at the other end of the thin shaft by a nut, and the front end of the movable rail of the slide rail can be hinged with a sucker by a through nail. The telescopic arm advancing and stopping reaction point and the retreating and stopping reaction point are arranged on one side of the hollow telescopic arm, the reaction point can be enabled to be in approximate reaction with the L-shaped baffle, a hole is formed in the proper position of the bottom of the hollow telescopic arm and used for installing a hydraulic cylinder movable rod limiting nail, the hollow telescopic arm is controlled by the hydraulic cylinder to advance and retreat along a slide rail arranged on a hanging basket under the control of a program, and therefore the suction and the separation of a suction disc arranged in front of the telescopic arm and a wall surface are completed.

If the invention is used on high-rise wall surface cleaning equipment, after a working procedure is started, the hydraulic cylinder controls the telescopic arm to extend forwards and retreat. When the hydraulic cylinder stretches forwards, the sucker at the front end of the movable rail of the sliding rail in the hollow telescopic arm also stretches forwards, when the sucker is in contact with the wall surface, the movable rail and the L-shaped baffle welded on the movable rail retreat, when the baffle is in contact with a reaction point of an advancing stop point, the forward stretching stops, the negative pressure valve opens the sucker to be sucked with the wall surface, then the hydraulic cylinder can control the telescopic arm to retreat, when the L-shaped baffle is in contact with the retreating reaction point, the retreating stops, and then the pulley in front of the wall device is in contact with the wall surface, at the moment, the cleaning equipment is tightly combined with the wall surface and keeps a certain distance from the wall surface to complete the cleaning task.
