Electric leveling device of window cleaning machine platform

Abstract

The invention discloses an electric leveling device of a window cleaning machine platform, belonging to the technical field of the cleaning of outer walls of buildings. The electric leveling device comprises a driving device, a transmission shaft device, a tensioning wheel mechanism, a transmission chain, a leveling device frame, a fixing pulley device, two screw rod mechanisms and a horizontal shifting pulley mechanism, wherein the driving device, the fixing pulley device and the transmission shaft device are respectively fixed on the leveling device frame, the first screw rod mechanism and the second screw rod mechanism are respectively fixedly arranged on two sides of the leveling device in parallel and are connected by the transmission chain, two ends of the transmission device are respectively connected with the driving device and the first screw rod mechanism, the tensioning wheel mechanism is fixedly arranged on the leveling device frame and meshed with the transmission chain, and two ends of the horizontal shifting pulley mechanism are respectively sleeved on the two screw rod mechanisms. Through changing the length of a steel wire rope inside a lifting mechanism to balance out the length changes of the steel wire rope during the expansion of a telescopic platform, the invention avoids the fault brought by man-made maloperations.

Description

technical field [0001] The invention relates to a device in the technical field of building exterior wall cleaning, in particular to an electric leveling device for a window cleaning machine platform. Background technique [0002] Today, in the tide of historical development, human material civilization has achieved unprecedented development in various fields and industries. The window cleaning machine industry has grown from scratch, and has achieved rapid progress in just a few decades. , window cleaning machines with various functions and special requirements are being perfected day by day. However, in the field of window cleaning machines, the lifting mechanism with a large load-carrying capacity has always been a technical difficulty for multi-layer coil winding window cleaning machines. Therefore, under the condition of limited lifting capacity, it is necessary to reasonably allocate The force is crucial, and usually, the bearing force on both sides of the suspension ...

Problems solved by technology

However, in the field of window cleaning machines, the lifting mechanism with a large load-carrying capacity has always been a technical difficulty for multi-layer coil winding window cleaning machines. Therefore, under the condition of limited lifting capacity, it is necessary to reasonably allocate The force is crucial, and usually, the bearing force on both sides of the suspension is not equal. In the case of unequal force, the change of the wire rope is more obvious as the length changes, and the result will lead to The extension of the platform and the inclination of the platform are getting more and more serious, which makes the telescopic platform prone to accidents

[0003] After searching the existing technology, it is found that there is no relevant electric leveling device in China at present. At present, there is only an electric telescopic sub-platform mechanism in China. This mechanism needs a hydraulic system to make the platform unfold. Because this structure relies on counterweights To balance the front sub-platform, since the whole system consists of two suspension points, the stability of the platform is poor during use, and it is difficult to fully guarantee the level of its sub-platform
