Background

The plastering machine replaces manual work to plaster cement mortar on the wall body, and has the advantages of high efficiency, time saving, labor saving and the like. Existing wall plasterers are generally provided with a set of upright rails, which are usually formed by 2 rails arranged parallel and vertically, called left and right rails. The left rail and the right rail are respectively provided with a second rack, the wall plastering machine head is provided with a driving gear, and the wall plastering machine head can do lifting motion along the vertical rail through the matching of the driving gear and the second rack, so that the functions of plastering from bottom to top and press polish from top to bottom are realized.

However, the length of the vertical rail of such a wall plastering machine is fixed, and the floor height of the current residential floor is generally about 3 meters, and the length of the vertical rail is required to be about 3 meters. However, the height of the door opening is usually only about 2 meters, so that the vertical rail can pass through the door opening after being inclined or detached, which causes much inconvenience to constructors and greatly reduces the construction efficiency.

The patent document with publication number CN203755619U discloses a wall plastering machine with a liftable upright rail, which comprises an underframe, an upright rail and a wall plastering machine head; the upright rail comprises a first left rail piece, a second left rail piece, a third left rail piece, a first right rail piece, a second right rail piece and a third right rail piece; the rail pieces on the same side can slide mutually; a first blocking device is arranged between the third left rail piece and the first left rail piece, and a second blocking device is arranged between the third right rail piece and the first right rail piece; the wall plastering machine head is also provided with a first clamping piece, a second clamping piece, a left rotating wheel and a right rotating wheel for walking; the first left track piece and the first right track piece are connected to the underframe; the top end of the second left rail piece and the top end of the second right rail piece are both connected to a cross beam piece; the device also comprises a hydraulic cylinder; the cylinder barrel of the hydraulic cylinder is connected with the underframe, and the rod of the hydraulic cylinder is connected with the cross beam piece. The patent has the defects that: in the process of plastering, the first fastener of the machine head of plastering need press the card fender portion of the lever member of the first blocking device and just can pass through the first blocking device smoothly, thereby the machine head of plastering is walked to the third left rail member from the first left rail member, and even if the first fastener on the machine head of plastering does not press the card fender portion of the lever member of the first blocking device, the machine head of plastering still can continue to rise, forcibly let the first fastener pass through the first blocking device, damage the first fastener or even the machine head of plastering. In addition, the hydraulic cylinder is used as a transmission part of the vertical rail, so that the manufacturing cost is high, and the hydraulic part is easy to damage due to the fact that the working environment is severe and much dust is generated.
