Description

Technical Field

[0001] The present invention relates to the technical field of construction machinery, and more specifically, to a device for cleaning the surface of a building material template. Background Art

[0002] Aluminum alloy building formwork technology has a history of more than 50 years abroad and is used in various fields of reinforced concrete building structures. It has been widely used in developed countries such as the United States, Canada, Japan, Germany, and emerging industrial countries such as South Korea, Singapore, Malaysia, the Philippines, India, Mexico, and Brazil, and has achieved good economic and social benefits. It has also been used in Hong Kong and Macao for more than 10 years.

[0003] At present, my country is in the process of rapid urbanization, and high-rise buildings are springing up in various provinces and cities. High-rise and super-high-rise buildings are mainly made of reinforced concrete. Building material formwork is the most ideal tool formwork at present, which plays a key role in solving the problems of large consumption of wood resources by wooden formwork and shortage of skilled workers in the construction industry.

[0004] Building material formwork has the characteristics of light weight, easy disassembly and assembly, high rigidity, large board surface, few joints, good stability, high precision, smooth and clean poured concrete, long service life, many turnover times, good economy, high recycling value, fast construction progress, high construction efficiency, safe and tidy construction site, good construction image, low dependence on machinery, wide range of applications, etc. It plays an important role in promoting building energy conservation and environmental protection and the process of building industrialization and has practical operational significance.

[0005] After use, there is usually a lot of cement dirt left on the surface of the building material formwork, and it cannot be put into use directly. The general treatment method is to soak and remove it with chemical agents, but the building material formwork cleaned with chemicals will have residual chemical substances, so it is often difficult to pass environmental protection standards, and the cost of using chemical cleaning is high and the efficiency is low.

[0006] Existing physical cleaning methods generally use rollers for washing, but roller washing is not complete and is likely to cause damage to the surface of the building material formwork. Summary of the invention

[0007] In order to overcome at least one defect of the above-mentioned prior art, the present invention provides a building material template surface cleaning device, which can effectively clean sticky substances on the plate to avoid damaging the surface of the building material template, and can also effectively clean the reinforced surface on the building material template.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is: a building material template surface cleaning device, including a frame and a transmission device arranged on the frame, the transmission device includes a driving shaft, a plurality of driving shafts are rotatably arranged on the frame, the building material template is placed on the driving shaft for transmission, and also includes an upper rotary flusher and a lower rotary flusher, the upper rotary flusher is arranged above the building material template, the lower rotary flusher is arranged below the building material template, and the lower rotary flusher includes a forward flusher and a reverse flusher.

[0009] In this device, the building material template is placed on the driving shaft, and the building material template is driven to move by the rotation of the driving shaft. The upper rotating flusher and the lower flushing template spray high-pressure water to flush the upper and lower surfaces of the building material template respectively, and the cement slag on the upper and lower surfaces of the building material template is flushed and peeled off. In addition, the upper rotating flusher and the lower rotating flusher can form a circular flushing surface when working, so that the cleaning area can be covered to the maximum extent, ensuring that the building material template is flushed clean. In addition, since the lower surface of the building material template is a reinforced surface with a relatively complex structure, the forward flusher and the reverse flusher are used to flush its lower surface, ensuring that the flushing area can cover the reinforcement ribs on the lower surface, ensuring that it is cleaned. By using this device to clean the surface of the building material template, the chemical residues generated by the existing chemical means of soaking and descaling are avoided, which is more environmentally friendly and convenient. Flushing with high-pressure water has a good cleaning effect and can avoid damage to the surface of the building material template. The cleaning efficiency is high, and the device can also cover the complex reinforced surface for cleaning, ensuring that all positions on the surface can be cleaned.

[0010] Furthermore, the structures of the upper rotating washer, the forward rotating washer and the reverse rotating washer are the same, and all include a water inlet, a rotating mechanism and a washing arm. The washing arm is connected to the rotating mechanism, and the rotating mechanism drives the washing arm to rotate. The washing arm and the rotating mechanism are both provided with a water flow channel connected to the water inlet, and the washing arm is provided with a plurality of nozzles connected to the water flow channel. The water inlet is connected to high-pressure water, and the high-pressure water is sprayed out through the nozzle through the water flow channel. At the same time, the rotating mechanism drives the washing arm to rotate, and the water spraying trajectory follows the rotating trajectory of the washing arm. In order to further ensure the washing area, a plurality of nozzles are provided on the washing arm, so that when the rotating mechanism rotates, a circular spraying surface can be formed to ensure that the washing area can be covered to the maximum extent. In addition, the circular area formed by the rotation of the washing arm is larger than the area of ​​the washing surface of the building material template, so that the washing surface of the building material template can be completely washed. In order to ensure sufficient pressure, the nozzle adopts a high-pressure nozzle, so that the water pressure sprayed from the nozzle is sufficient, and the stubborn dirt sticking to the surface of the building material template can be effectively washed.

[0011] Furthermore, the cleaning arm includes a first cleaning arm and a second cleaning arm, and the rotation trajectory of the nozzle on the first cleaning arm and the rotation trajectory of the nozzle on the second cleaning arm are interlaced. In this way, when the cleaning arm rotates, the flushing trajectories formed by the high-pressure water sprayed by the nozzles on the first cleaning arm and the second cleaning arm will not overlap, which can increase the spraying area and effectively improve the cleaning efficiency.

[0012] Furthermore, the nozzle forms an installation angle β with the vertical plane, and the nozzles on the first cleaning arm and the nozzles on the second cleaning arm are installed at opposite angles. By setting the installation angle β, the area formed by the water spray finally hitting the surface of the building material template can be larger than the rotation plane of the cleaning arm, so that the cleaning area can be expanded. In addition, in order to ensure that the loss of water spray pressure is reduced, the installation angle β is set to 10°-20°, preferably 15°.

[0013] Furthermore, the rotating mechanism includes a rotating shaft, a connector, a driven wheel, a driving wheel and a motor, wherein the driving wheel is connected to the output shaft of the motor, the driving wheel is belt-driven with the driven wheel, one end of the rotating shaft is connected to the driven wheel, and the other end is connected to the connector, and the cleaning arm is symmetrically arranged on the connector. The driving wheel is connected to the motor, and the rotation of the driving wheel is driven by the motor. The driving wheel and the driven wheel are belt-driven to drive the driven wheel to rotate. The rotating shaft is installed at the center of the driven wheel, and the rotating shaft drives the cleaning arm installed on the connector to rotate, so as to change the spraying trajectory, and the spraying coverage area is the area of ​​the circle rotated by the cleaning arm. In addition, in this device, in order to facilitate the adjustment of the installation angle β of the nozzle, the first cleaning arm and the second cleaning arm are respectively connected to the connector through double-headed teeth. When replacing building material templates of different sizes, the cleaning arm can be easily disassembled from the double-headed teeth and replaced, which is more convenient for repair and maintenance. The connection through the double-headed teeth has good sealing and high connection strength. Even if the connection is used for a long time, there will be no leakage and loosening problems, and the reliability is high.

[0014] Furthermore, the transmission device also includes a driven shaft, which is arranged above the driving shaft. The driven shaft is used to clamp the building material template, and the position of the driven shaft can be adjusted up and down. The distance between the driven shaft and the driving shaft is adjusted according to actual conditions. When the building material template enters the working range of the driven shaft, the driven shaft and the driving shaft clamp the building material template up and down, which can prevent the building material template from moving up and down due to the vibration of the machine itself during transportation, thereby ensuring the stability of the transmission.

[0015] Furthermore, the driving shaft is provided with a guide wheel. When the building material template is transported, the guide wheel adjusts the direction of the building material template so that the building material template is transported along the working direction to avoid left-right displacement.

[0016] Furthermore, the driven shaft is provided with a driven gear, the driving shaft is provided with a driving gear, and the driving gear meshes with the driven gear. When the plate passes through the driving shaft and the transmission shaft, the meshing of the gears can ensure that the speed of the driving shaft and the driven shaft is consistent, making the transportation smoother.

[0017] Furthermore, it also includes a gantry, and the upper rotary washer is provided with a mounting channel steel, and the upper rotary washer is mounted on the gantry through the mounting channel steel so as to be adjustable up and down. The height of the upper rotary washer can be adjusted according to the actual height of the building material template.

[0018] Furthermore, it also includes a shield, and the washing arm is arranged in the shield. The height of the shield is greater than the height of the washing arm, so that when the washing arm rotates, the high-pressure water sprayed is blocked by the shield to prevent the sprayed water from flying out from the side under the inertia of the washing arm rotation, and it can also prevent foreign objects from touching the high-speed rotating washing arm during the washing process, causing damage to the washing arm.

[0019] Compared with the prior art, the beneficial effects are:

[0020] 1. This flusher uses high-pressure water to flush the building material template, which can effectively clean the sticky materials on the board and avoid damaging the surface of the building material template;

[0021] 2. This device can fully clean the reinforced surface of the building material template, and the cleaning coverage area of ​​this device is large and the cleaning efficiency is high;

[0022] 3. This device can form a circular spraying surface to ensure that the cleaning area can be covered to the maximum extent and the cleaning surface of the building material template can be completely cleaned;

[0023] 4. The device is equipped with a protective cover which can not only avoid water splashing, but also protect the cleaning arm, preventing mechanical damage and accidental personal injury. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0032] like Figure 1 , 2 As shown, a surface cleaning device for building material templates includes a frame 1 and a transmission device 2 arranged on the frame 1, wherein the transmission mechanism is composed of a plurality of driving shafts 21 rotatably arranged on the frame 1, a driven shaft 22 which can be adjusted up and down and arranged above the driving shaft 21, and a guide wheel 23 arranged on the driving shaft 21. The building material template is driven by the transmission device 2, and the rotary washer is arranged above the building material template. When the building material template is transported, the guide wheel 23 adjusts the direction of the building material template so that the building material template is transported along the working direction to avoid left and right displacement. When the building material template enters the working range of the driven shaft 22, the driving shaft 21 and the transmission shaft clamp the building material template up and down, and continue to transport the building material template in the working direction, so that the building material template can be prevented from being shifted left and right, and the building material template can also be prevented from being shifted up and down due to the vibration of the machine itself during transportation. In addition, the driven shaft 22 is provided with a driven gear 25, and the driving shaft 21 is provided with a driving gear 24, and the driving gear 24 is meshed with the driven gear 25. When the plate passes through the driving shaft 21 and the transmission shaft, the meshing of the gears can ensure that the rotation speeds of the driving shaft 21 and the driven shaft 22 are consistent, making the transportation smoother.

[0033] An upper rotary flusher 4 is installed above the frame 1 in the device, and a lower rotary flusher 5 is installed below the frame 1. The upper rotary flusher 4 is arranged above the upper surface of the building material template, and the lower rotary flusher 5 is arranged below the lower surface of the building material template. In addition, since the lower surface of the building material template is a reinforced surface and the structure is relatively complex, the lower rotary flusher 5 is arranged as a forward-rotating flusher 51 and a reverse-rotating flusher 52. The forward-rotating flusher 51 and the reverse-rotating flusher 52 have opposite rotation directions. The lower surface is flushed by the forward-rotating flusher 51 and the reverse-rotating flusher 52 to ensure that the flushing area can cover the reinforcement ribs on the lower surface and ensure that it is clean.

[0034] like Figure 3-5As shown, the upper rotating flusher 4, the forward rotating flusher 51 and the reverse rotating flusher 52 have the same structure, all of which include a water inlet 41, a rotating mechanism and a cleaning arm. The cleaning arm is connected to the rotating mechanism, and the rotating mechanism drives the cleaning arm to rotate. The cleaning arm and the rotating mechanism are both provided with a water flow channel connected to the water inlet 41. The cleaning arm is provided with a plurality of nozzles 44 connected to the water flow channel, wherein the rotating mechanism includes a rotating shaft 401, a connecting body 402, a driven wheel 403, a driving wheel 404 and a motor 405. The driving wheel 404 is connected to the output shaft of the motor 405, and the driving wheel 404 is driven by the driven wheel 403. One end of the rotating shaft 401 is connected to the driven wheel 403, and the other end is connected to the connecting body 402. The cleaning arm is symmetrically arranged on the connecting body 402. The driving wheel 404 is connected to the motor 405, and the motor 405 drives the driving wheel 404 to rotate. The driving wheel 404 and the driven wheel 403 are driven by a belt transmission to drive the driven wheel 403 to rotate. The rotating shaft 401 is installed at the center of the driven wheel 403. The rotating shaft 401 drives the cleaning arm installed on the connecting body 402 to rotate, thereby changing the spraying trajectory. The spraying coverage area is the area of ​​the circle rotated by the cleaning arm.

[0035] In the present device, the cleaning arm is provided as a first cleaning arm 42 and a second cleaning arm 43, and the first cleaning arm 42 and the second cleaning arm 43 are respectively connected to the connector 402 through double-ended teeth. When replacing building material templates of different sizes, the cleaning arm can be easily removed from the double-ended teeth and replaced, which makes repair and maintenance more convenient. The connection through the double-ended teeth has good sealing performance and high connection strength. Even if the connection is used for a long time, there will be no leakage or loosening problems, and the reliability is high. Figure 5 As shown, the nozzle 44 on the cleaning arm forms an installation angle β with the vertical plane, and the installation angle can be adjusted by adjusting the rotation angle of the first cleaning arm 42 and the second cleaning arm 43 relative to the connector 402. The double-headed connection method can facilitate adjustment and fixation by the staff. In addition, the installation angles of the nozzle 44 on the first cleaning arm 42 and the nozzle 44 on the second cleaning arm 43 are opposite. By setting the installation angle β, the area formed by the water spray finally hitting the surface of the building material template can be larger than the rotation plane of the cleaning arm, so that the cleaning area can be expanded. In addition, in order to ensure that the loss of the water spray pressure is reduced, the installation angle β is set to 10°-20°, preferably 15°.

[0036] In addition, in this embodiment, the rotation trajectory of the nozzle 44 on the first cleaning arm 42 and the rotation trajectory of the nozzle 44 on the second cleaning arm 43 are interlaced. In this way, when the cleaning arms rotate, the flushing trajectories formed by the high-pressure water sprayed by the nozzles 44 on the first cleaning arm 42 and the second cleaning arm 43 will not overlap, which can increase the spraying area and effectively improve the cleaning efficiency. Preferably, as Figure 6As shown, the distance between the nozzle 44 on the first cleaning arm 42 and the center of the rotating shaft 401 is L, the spacing between the nozzles 44 on the first cleaning arm 42 is a, and the distance between the nozzles 44 on the second cleaning arm 43 and the center of the rotating shaft 401 of the corresponding number of nozzles on the first cleaning arm 42 is L'. The distance between the nozzle 44 on the first cleaning arm 42 and the nozzle 44 on the second cleaning arm 43 is set according to the formula L'=La / 2. When cleaning in this way, the cleaning trajectory is as shown in the figure, the solid line represents the cleaning trajectory of the first cleaning arm 42, and the dotted line represents the cleaning trajectory of the second cleaning arm 43. The cleaning trajectories of the first cleaning arm 42 and the second cleaning arm 43 do not overlap with each other. Therefore, this setting can increase the spraying area and effectively improve the cleaning efficiency.

[0037] In this embodiment, in order to facilitate debugging and installation, a gantry 3 is also provided, and a mounting channel steel 45 is provided on the upper rotary flusher 4. The upper rotary flusher 4 is mounted on the gantry 3 so as to be adjustable up and down through the mounting channel steel 45. The height of the upper rotary flusher 4 can be adjusted according to the actual height of the building material template.

[0038] In addition, a protective cover 46 is included, and the washing arm is arranged in the protective cover 46. The height of the protective cover 46 is greater than the height of the washing arm, so that when the washing arm rotates, the high-pressure water sprayed is blocked by the protective cover 46 to prevent the sprayed water from flying out from the side under the inertia of the washing arm rotation, and also to prevent foreign matter from touching the high-speed rotating washing arm during the washing process, resulting in damage to the washing arm.

[0039] The implementation process of this device is as follows:

[0040] The building material template to be cleaned is placed on the driving shaft 21, and the left and right position of the building material template is limited by the guide wheel 23 on the driving shaft 21, and the upper and lower positions of the building material template are limited by the driven wheel 403 on the driving shaft 21. The driving shaft 21 rotates to drive the building material template to move, and the upper rotary flusher 4 and the lower rotary flusher 5 use high-pressure water to flush the upper surface and the lower surface of the building material template respectively. Specifically, the high-pressure water is connected to the water inlet 41, and the high-pressure water passes through the water channel and the nozzle 44 to spray the high-pressure water. At the same time, the motor 405 drives the rotation of the driving wheel 404. The driving wheel 404 and the driven wheel 403 are driven by a belt transmission to drive the driven wheel 403 to rotate. The rotating shaft 401 is installed at the center of the driven wheel 403. The rotating shaft 401 drives the cleaning arm installed on the connecting body 402 to rotate, so as to change the spraying trajectory. The spraying coverage area is the area of ​​the circle rotated by the cleaning arm. Figure 7As shown, in addition, since the lower surface of the building material template is a reinforced surface with a relatively complex structure, the lower surface is flushed by the forward-rotating flusher 51 and the reverse-rotating flusher 52 to ensure that the flushing area can cover the reinforcement ribs on the lower surface, and to ensure that the cleaning is thorough while the rotating mechanism drives the cleaning arm to rotate. As shown in the figure, the forward-rotating flusher 51 sprays water in the direction of the A surface of the reinforcement ribs of the building material template, and the reverse-rotating flusher 52 sprays water in the direction of the B surface of the building material template, so that the cement residue attached to the reinforcement ribs can also be well washed. This device can avoid the chemical residues produced by the existing chemical means of soaking and descaling, which is more environmentally friendly and convenient, and flushing with high-pressure water has a good cleaning effect and can avoid damage to the surface of the building material template, with high cleaning efficiency, and this device can also cover the complex reinforced surface for cleaning, ensuring that all positions on the surface can be cleaned.
