Description

Technical Field

[0001] The present invention relates to the technical field of wall panel component cutting, and in particular to a component cutting device for wall panel installation and a use method thereof. Background Art

[0002] Wallboard is the name of furniture parts in Ming and Qing dynasties. The vertical panels on the left and right sides of the furniture are collectively called "side panels" or "wall panels". Now it refers to a kind of building material. It is a house structure with a load-bearing system composed of walls and floor slabs. The load-bearing walls of the wallboard structure can be made of bricks, blocks, prefabricated or cast-in-place concrete. According to the materials used and the construction methods, it can be divided into three categories: mixed structure, assembled large-plate structure, and cast-in-place wallboard structure.

[0003] Existing wall panels require the assistance of fixing components to be correctly installed, and the fixing components are usually composed of aluminum alloy slats, which can effectively cover the wall and maintain a horizontal effect. Since there is a length error in the processing of each aluminum alloy slat, and the aluminum alloy slat is not fixed to the wall, it is impossible to clearly see whether it is of the right length with the wall. When it is found that the current aluminum alloy slat and the wall are not inappropriate in length and need to be cut, it is usually necessary to manually climb a carpenter's ladder and use an electric hand saw to cut the aluminum alloy slat. Manual climbing not only has hidden dangers, but also the center of gravity of the manually operated electric hand saw is unstable, and it is easy to cut the aluminum alloy slat obliquely, thereby affecting the appearance and the later assembly of the wall panels.

[0004] To this end, we have designed a component cutting device and a method for using it for wall panel installation. Summary of the invention

[0005] The purpose of the present invention is to solve the problems of construction safety hazards in the prior art and errors in manual cutting that affect the aesthetics, and to propose a component cutting device for wall panel installation.

[0009] Preferably, a hydraulic push rod is provided on the first telescopic rod, the hydraulic push rod is fixedly connected to the aluminum alloy rod, the rotating shaft is fixedly connected to the integrated drive device through an auxiliary rod, and the rotating shaft is rotatably connected to the first telescopic rod.

[0010] Preferably, the integrated drive device is provided with a first shaft, the saw blade is provided with a connector, the connector is provided with a second shaft, and both ends of the second telescopic rod are fixedly connected to the first shaft and the second shaft.

[0011] Preferably, a cavity is opened in the two second telescopic rods, and a hydraulic telescopic rod for auxiliary stretching is provided in the two second telescopic rods. Two seat bodies are provided in the cavity, and the seat bodies are fixedly connected to the second telescopic rods. The two seat bodies are connected to each other by restraining the telescopic rod.

[0012] Preferably, the saw blade is rotatably connected to a connecting body, and a protective half-cover is provided on the connecting body for reducing splashing of debris.

[0013] Preferably, the integrated drive device is symmetrically provided with an aluminum alloy connection cover, the aluminum alloy connection cover is provided with a center plate, a power transmission pipe is provided inside the aluminum alloy connection cover, a cavity is opened on the center plate, and the cavity is adapted to the connector.

[0014] Preferably, a third shaft body for rotating the clamping rod is symmetrically provided on the center plate, a mounting buckle rod is provided on the third shaft body, the mounting buckle rod is fixedly connected to the clamping rod, a driving shaft is symmetrically provided on the center plate, and the third shaft body is connected to the driving shaft through a driving connecting rod.

[0015] Preferably, a limiting ring body is provided on the center plate, and the limiting ring body is fixedly connected to the connecting body. An auxiliary spring shaft is provided at one end of the center plate, and the auxiliary spring shaft is fixedly connected to the limiting ring body. A front fastener is fixedly installed on the side wall of the integrated drive device. A fourth axis body is provided on the limiting ring body and the front fastener. The two fourth axis bodies are connected to each other through a third telescopic rod, and the third telescopic rod rotates on the fourth axis body.

[0016] Preferably, slide rails are symmetrically arranged at the bottom of the center plate, and the limiting ring body slides on the slide rails through sliders.

[0017] A method for using a component cutting device for wall panel installation, the specific steps are as follows:

[0018] S1. First, the worker holds an aluminum alloy rod and stands under the aluminum alloy slat to be cut, making sure that the battery is sufficiently charged. He presses the operating button according to the height of the aluminum alloy slat to lift the first telescopic rod upward and presses the operating button again to stop it when it is about to reach the aluminum alloy slat. Then, the worker presses the operating button according to the angle to rotate the rotating shaft to change the angle of the integrated drive device on the aluminum alloy rod. Then, the clamping rod on the center plate is adjusted according to the width of the aluminum alloy slat so that the width between the two clamping rods is against the side wall of the aluminum alloy slat.

[0019] S2. The worker then determines whether the cutting work can be carried out correctly according to the current angle of the saw blade. For example, if there is a distance between the saw blade and the aluminum alloy slat, the worker can press the operating button to push the first axis and the auxiliary spring axis on the center plate forward, and the connector moves under the restriction of the bottom slide rail of the center plate. At the same time, the second axis at the top of the connector and the second telescopic rod between the first axis produce a stretching action to increase the stretching force of both. At the same time, the third telescopic rod is pushed and stretched forward under the control of the fourth axis on the limiting ring and the front fastener until the saw blade reaches the aluminum alloy slat that can be cut, then it stops and the saw blade is started immediately.

[0020] The beneficial effects of the present invention are:

[0021] 1. The present invention arranges the first telescopic rod and the rotating shaft so that workers can hold the aluminum alloy rod to align the aluminum alloy slats for operation, and effectively adjust the angle and height of the saw blade according to their own position, thereby effectively cutting the aluminum alloy slats on the wall, avoiding manual climbing of ladders and holding electric hand saws for cutting. Compared with the prior art, it can effectively improve the efficiency of workers in cutting aluminum alloy slats and reduce safety hazards during cutting.

[0022] 2. The present invention arranges the second telescopic rod and the hydraulic telescopic rod so that the saw blade can be adjusted in length according to the on-site environment, thereby avoiding the situation where the aluminum alloy slats are too thin to be cut. At the same time, the hydraulic telescopic rod can improve the telescopic effect of the second telescopic rod and has a connecting force, thereby improving the stability of the saw blade length adjustment. At the same time, under the restrictions of the first axis and the second axis, the connection between the connector and the integrated drive device is improved, thereby improving the smoothness of the saw blade adjustment.

[0023] 3. The present invention sets a length limit for saw blade adjustment through the arrangement of a center plate and a limiting ring body, thereby preventing the saw blade adjustment distance from being too long and affecting the use effect. At the same time, under the restriction of the limiting ring body, the connector can be effectively moved on the slide rail at the bottom of the center plate, reducing the deviation of the connector under the centrifugal motion of the saw blade, thereby improving the stability of the saw blade length adjustment.
