Description

Technical Field

[0001] The present invention belongs to the technical field of construction industrial equipment, and particularly relates to a cutting mechanism for the decorative layer of a building facade. Background Art

[0002] With the advent of the era of building stock, more and more building structures are facing a lot of inspection and maintenance work as their service life increases. Taking exterior wall tiles as an example, in some old communities, due to their long-term exposure to the outside, under the coupled action of multiple physical fields such as rain, temperature difference, and wind load, a large number of exterior wall tiles have problems such as hollowing, cracking, and water seepage. Currently, during the process of treating the above problems, handheld impact demolition equipment is mainly used for demolition, and there are often situations where large areas of exterior wall tiles fall off during the construction process. At the same time, the building's structural layer is extremely vulnerable to damage during the demolition process, and during the demolition process, the demolished construction waste is also irregular, which is not convenient for subsequent cleaning and affects the progress of the rectification work of the building facade. Summary of the Invention

[0003] The purpose of the present invention is to provide a cutting mechanism for the decorative layer of a building facade to overcome the defects of the prior art, improve the cutting efficiency of the decorative layer, avoid the situation of large-area shedding at the same time, ensure the regularity and unity of the construction waste, and at the same time, various cutting shapes can be formed by the cutter head only by adjusting the angle of the movable part to meet the cutting requirements of the decorative layers of different buildings.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A cutting mechanism for the decorative layer of a building facade includes a movable part and a plurality of cutter heads fixed on the movable part. Each cutter head is connected to a driving device through a water pipe. The driving device is connected to an external water source and can pressurize the water source. The driving device includes a box body and a support frame arranged on the box body. The support frame extends in the direction of the cutter head. The part of the movable part between two cutter heads is detachably connected to the support frame to adjust the distance between the two cutter heads and the formed cutting shape.

[0017] Figure 2 shows a schematic structural diagram of an embodiment of the present invention in another direction;

[0018] In the drawings, the same components are denoted by the same reference numerals. The drawings are not drawn to actual scale.

[0020] 1 - cutter head, 2 - movable member, 3 - box body, 4 - support frame, 5 - column, 6 - roller, 7 - limiting pulley, 8 - threaded hole, 401 - cross bar, 402 - reinforcing bar. Detailed implementation mode

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] The present invention provides a cutting mechanism for the decorative layer of a building facade, as Figure 1 shown, including a movable member 2 and a plurality of cutter heads 1 fixed on the movable member 2. Each cutter head 1 is connected to a driving device through a water pipe. The driving device is communicated with an external water source and can pressurize the water source. The driving device includes a box body 3 and a support frame 4 arranged on the box body 3. The support frame 4 extends in the direction of the cutter head 1. The part of the movable member 2 between two cutter heads 1 is detachably connected to the support frame 4 to adjust the distance between the two cutter heads 1 and the cutting shape formed;

[0023] It should be noted that the driving device pressurizes the external water source and sprays it through the cutter head 1 to form a water jet to cut the decorative layer. The movable member 2 is detachably connected to the support frame 4, that is, the angle and distance between the cutter heads 1 can be adjusted with the detachable connection point as the center, so as to form various different cutting shapes to be applicable to various different building facade structures. A compression system is arranged in the driving device. The compression system is connected to an external power supply. The compression system is used to pressurize the external water source, and a voltage transformation device is also provided in the compression system, that is, the water pressure can be adjusted according to the material strength of different decorative layers, so that only the decorative layer is cut without damaging the structural layer of the building facade;

[0024] Specifically, as Figure 1 shown, the movable member 2 has a rectangular structure. A cutter head 1 is fixed at each end of the movable member 2. The cutter head 1 has a frustum structure, and its larger-diameter end is connected to the water pipe. Corresponding threaded holes 8 are opened on the support frame 4 and the movable member 2. The movable member 2 is connected to the support frame 4 through bolts, that is, through the connection method of bolts and threaded holes 8, that is, the cutter heads 1 on the movable member 2 can be adjusted to different distances and angles with the bolt as the center, and it is also convenient for construction workers to disassemble and assemble;

[0025] In one embodiment, as Figure 2 shown, a plurality of columns 5 are further arranged at the bottom of the box body 3. A roller 6 is arranged at the end of each column 5 away from the box body 3, that is, the driving device is supported by the columns 5, so that the operator can complete the disassembly operation by pushing the driving device. Compared with the conventional hand-held impact device, it is more time-saving and labor-saving, and greatly improves the disassembly efficiency;

[0026] Furthermore, as Figure 1 shown, a limit pulley 7 is further arranged on the side of the box body 3 in the same direction as the spraying direction of the cutter head 1. The limit pulley 7 is used to contact the building facade to control the cutting distance between the cutter head 1 and the building facade;

[0027] It should be noted that after adjusting the corresponding water jet cutting strength according to the material of the decorative layer, the distance between the water jet and the building exterior can be maintained through the limit pulley 7, that is, the cutting strength of the water jet is maintained, so as to avoid damage to the structural layer due to the water jet being too close to the building exterior during long-term construction caused by the mistakes of construction workers;

[0028] In one embodiment, the larger-diameter end of the cutter head 1 is embedded in the movable member 2. A through hole for the water pipe to penetrate is provided at the end of the movable member 2, and the water pipe is communicated with the side wall of the cutter head 1, which is convenient for fixing the position of the cutter head 1 and preventing it from shifting under the action of water pressure and affecting the cutting operation;

[0029] In one embodiment, as Figure 1 shown, the support frame 4 includes two horizontal bars 401 extending in the horizontal direction. A plurality of reinforcing bars 402 are arranged at intervals between the two horizontal bars 401, and the threaded holes 8 are opened on the reinforcing bars 402, which ensures the structural strength of the support frame 4 and the stability of the movable member 2 installed on the support frame 4, and avoids shaking or falling off under the action of water pressure and affecting the uniformity of the construction waste after cutting, which is convenient for subsequent cleaning and recycling of the construction waste;
