Problems solved by technology

The hanging basket needs a travel switch to control the limit position of the basket during the movement. Because the upper travel switch is installed on the safety lock, the hanging basket is shaking when it is running. When the standard travel switch connecting plate encounters obstacles in any direction It may be bent or damaged immediately, resulting in the failure of the upper limit control. Therefore, it is of great engineering significance to develop a flexible, convenient and reliable anti-collision limit switch.

Embodiment Construction

[0011] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0012] like figure 1 As shown: the present invention mainly consists of bent steel plate (1), travel switch (2), buffer spring (3), connecting plate (4), height adjustment bolt (5), steel sleeve (6) and safety lock (7) Composition; the travel switch (2) is installed on the bent steel plate (1) to control the upper limit position, the travel switch (2) and the bent steel plate (1) are connected with a buffer spring (3), and the travel switch (2) The impact has a buffering effect. The buffer spring (3) passes through the steel sleeve (6), and is fixed on the connection plate (4) through the height adjustment bolt (5), and the connection plate (4) is fixed on the safety lock ( 7) on.

[0013] For specific applications, such as Figure 1 to Figure 2 As shown, the safety lock (7) moves up and down with the hanging basket body, and when it reaches the maximum...

Abstract

The invention relates to an anti-impact stroke switch. The anti-impact stroke switch comprises a bent steel plate, a stroke switch, a buffering spring, a connecting plate, a height adjusting bolt, a steel sleeve and a safety lock; the buffering spring is connected below the stroke switch and the bent steel plate and can realize a buffering effect for impact borne by the stroke switch; and a fixed end of the buffering spring is provided with the height adjusting bolt through which the height of the spring can be adjusted so that the height of the stroke switch can be controlled. According to the anti-impact stroke switch of the invention, the stroke switch is connected through the buffering spring, and the buffering spring will bend with the stroke switch no matter from which direction the stroke switch bears impact; and after being rest, the buffering spring can automatically rebound to an original position, so that normal work of upper limit control can be ensured.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and relates to high-altitude operation equipment, in particular to an anti-collision travel switch. Background technique [0002] The hanging basket is generally composed of a suspension mechanism, a track, a rail climber, a basket body and a safety system. The basket body can walk horizontally and move vertically along the track, and the staff can reach all facades of the building. It is mainly used for cleaning and maintenance of the outer windows and outer walls of ships, buildings or structures. With the improvement of urban construction requirements, it is required to carry out regular cleaning and maintenance operations on glass windows and exterior walls of buildings. In recent years, with the increase of inspection and maintenance work on the facade of high-rise or super high-rise buildings, the market demand for the hanging platform is increasing by virtue of its simple s...
