Description

Technical Field

[0001] The present invention relates to the technical field of construction machinery, and more specifically, to an oscillating nozzle and a building material template cleaning device having the oscillating nozzle. 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 swinging nozzle and a building material template cleaning device having a swinging nozzle, which can effectively clean sticky substances on the building material template and avoid damaging the surface of the building material template.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is: an oscillating nozzle, including a mounting seat, a nozzle, a driving device and a reciprocating swing mechanism, the nozzle is arranged on the mounting seat, the driving device is connected to the reciprocating swing mechanism, and the reciprocating swing mechanism is connected to the mounting seat to drive the mounting seat to swing back and forth.

[0009] In this device, the nozzle is externally connected to a high-pressure water pipeline, and high-pressure water can be sprayed out through the nozzle, wherein several nozzles are arranged on a mounting seat, and a driving device serves as a power to drive a reciprocating swinging mechanism, and the reciprocating swinging mechanism performs a reciprocating swinging motion, driving the mounting seat connected thereto, so that the mounting seat performs a reciprocating swinging action, thereby realizing swinging water spraying, and can rinse the surface of the building material template back and forth for multiple times, effectively removing sticky substances on the surface of the building material template, with high cleaning efficiency and without causing physical damage to the surface of the building material template.

[0010] Furthermore, the reciprocating swing mechanism is a crank rocker mechanism or a crank slider mechanism or a cam.

[0011] Further, the reciprocating swing mechanism includes a first driving gear, a first driven gear, a push rod and a transmission plate, and the mounting seat is provided with a rotating shaft on both sides, and the driving device is connected to the first driving gear to drive the first driving gear to rotate, and the first driving gear and the first driven gear are meshed, and one end of the push rod is eccentrically connected to the first driven gear, and the other end is hinged to one end of the transmission plate, and the end of the transmission plate is fixedly connected to the rotating shaft. The driving device drives the first driving gear to rotate, and the first driving gear drives the first driven gear to rotate, and the first driven gear drives the push rod eccentrically connected to it to move, and the push rod drives the transmission plate to reciprocate at a certain angle, thereby driving the swing of the mounting seat, realizing the change of the water spraying trajectory, realizing the reciprocating swing water spraying, and washing the building material template back and forth. Among them, the swing angle of the transmission plate is set to 40°-50°, which can ensure that the water sprayed by the nozzle can hit the surface of the building material template with a large pressure, and can also prevent the high-pressure water sprayed by the nozzle from deviating from the impact route to wash the position outside the building material template. In addition, the gear ratio of the first driving gear and the second driving gear used in the device can be adjusted according to the actual speed parameters of the driving device and production requirements, so as to adjust and control the swing rate of the mounting seat. In addition, in order to more conveniently adjust and control the swing rate of the gear while keeping the gear ratio unchanged, a speed regulating motor can be used as the driving device.

[0012] Furthermore, it also includes a bearing seat, a bearing and a gear shaft, wherein the bearing is installed on the bearing seat, the rotating shaft is rotatably connected to the bearing, the first driving gear and the first driven gear are respectively connected to the axis of the gear shaft, and the gear shaft is rotatably connected to the bearing. The bearing can reduce the friction of the rotating shaft, the first driving gear and the first driven gear. Compared with direct installation, the sliding friction is converted into rolling friction, which can better reduce friction and improve transmission efficiency, reduce energy loss, and extend service life.

[0013] Furthermore, a plurality of the nozzles are mounted on the mounting base, and the spraying direction of the nozzles is perpendicular to the mounting plane. In addition, the nozzles can also be tilted and arranged on the mounting plane according to actual needs.

[0014] Furthermore, the driving device is a motor, specifically a servo motor.

[0015] Furthermore, a building material template cleaning device includes a transmission device, the transmission device includes a frame, a driving shaft, a driven shaft and an oscillating nozzle, several driving shafts are rotatably arranged on the frame, the driven shaft is arranged above the driving shaft, the driving shaft is provided with a guide wheel, the building material template is driven by the transmission device, and the oscillating nozzle is arranged below the building material template.

[0016] When transporting the building material template, 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 and right displacement. When the building material template enters the working range of the driven shaft, the driving shaft and the transmission shaft clamp the building material template up and down, and continue to transport the building material template in the working direction. This can avoid left and right displacement of the building material template and avoid the vibration of the machine itself during transportation. This transmission device can ensure that the building material template is smooth during transportation and avoid the phenomenon of the building material template getting stuck. During the transportation of the building material template, the swing nozzle is started at the same time, so that the transportation and cleaning can be carried out simultaneously. The whole process is automated to ensure the continuity and efficiency of cleaning.

[0017] Furthermore, the driven shaft is provided with a second driven gear, the driving shaft is provided with a second driving gear, and the second driving gear meshes with the second driven gear. When the building material template 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.

[0018] Furthermore, the mounting seat is installed in the middle of the frame, the nozzle is arranged below the building material template, and the angle α between the length direction of the mounting seat and the length direction of the frame is 100°-120°, preferably 110°. This arrangement makes the nozzle water spraying trajectory not balanced with the frame, which effectively improves the cleaning efficiency compared with the nozzle water spraying trajectory being balanced with the frame.

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

[0020] 1. This device can use high-pressure water to repeatedly wash the building material template, which can effectively clean the sticky materials on the building material template and avoid damaging the surface of the building material template;

[0021] 2. Compared with the existing physical scrubbing, this device has a more efficient cleaning efficiency;

[0022] 3. In this device, the nozzle mounting frame and the frame are installed at an angle, which makes the nozzle water spray trajectory balanced with the frame and has higher cleaning efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings.

[0029] like Figure 1 , 2As shown, a swinging nozzle comprises a mounting seat 201, a nozzle 202, a driving device 203 and a reciprocating swing mechanism, wherein a plurality of nozzles 202 are arranged on the mounting seat 201, the driving device 203 is connected to the reciprocating swing mechanism, and the reciprocating swing mechanism is connected to the mounting seat 201 to drive the mounting seat 201 to swing back and forth, wherein the driving device 203 is a servo motor, and the reciprocating swing mechanism is a crank rocker mechanism or a crank slider mechanism or a cam, specifically, the reciprocating swing mechanism comprises a first driving gear 204, a first driven gear 205, a push rod 206 and a transmission plate 207, and a rotating shaft 208 is arranged on both sides of the mounting seat 201, the driving device 203 is connected to the first driving gear 204 to drive the first driving gear 204 to rotate, the first driving gear 204 is meshed with the first driven gear 205, one end of the push rod 206 is eccentrically connected to the first driven gear 205, and the other end is hinged to one end of the transmission plate 207, and the end of the transmission plate 207 is fixedly connected to the rotating shaft 208. It also includes a bearing seat 210, a bearing 209 and a gear shaft, wherein the bearing 209 is mounted on the bearing seat 210, the rotating shaft 208 is rotatably connected to the bearing 209, the first driving gear 204 and the first driven gear 205 are respectively connected to the axis of the gear shaft, and the gear shaft is rotatably connected to the bearing 209. The bearing 209 can reduce the rotational friction of the rotating shaft 208, the first driving gear 204 and the first driven gear 205.

[0030] The nozzle 202 is mounted on the mounting seat 201, and the spraying direction of the nozzle 202 is perpendicular to the mounting plane. In addition, the nozzle 202 can also be tilted on the mounting plane according to actual needs.

[0031] In the present swinging nozzle 202, the servo motor drives the first driving gear 204 to rotate, the first driving gear 204 drives the first driven gear 205 to rotate, the first driven gear 205 drives the push rod 206 eccentrically connected thereto to move, the push rod 206 drives the transmission plate 207 to swing back and forth at a certain angle, thereby driving the swing of the mounting seat 201, realizing the change of the water spraying trajectory, realizing the reciprocating swinging water spraying, and washing the building material template back and forth. Among them, the swinging angle of the transmission plate 207 is set to 40°-50°, so that the water spray of the nozzle 202 can hit the surface of the building material template with a large pressure, and this can also prevent the high-pressure water sprayed by the nozzle 202 from deviating from the impact route to wash the position outside the building material template. In addition, the gear ratio of the first driving gear 204 and the second driving gear 104 used in the present device can be adjusted according to the actual servo motor speed parameters and production requirements, so as to adjust and control the swing rate of the mounting seat 201.

[0032] like Figure 3As shown, a building material template cleaning device includes a transmission device, which includes a frame 101, a driving shaft 102, a driven shaft 103 and an oscillating nozzle 202. A plurality of driving shafts 102 are rotatably arranged on the frame 101, the driven shaft 103 is arranged above the driving shaft 102, a guide wheel 106 is arranged on the driving shaft 102, the building material template is driven by the transmission device, and the oscillating nozzle 202 is arranged below the building material template. The driven shaft 103 is provided with a second driven gear 105, the driving shaft 102 is provided with a second driving gear 104, and the second driving gear 104 is meshed with the second driven gear 105. When the building material template passes through the driving shaft 102 and the transmission shaft, the meshing of the gears can ensure that the rotation speeds of the driving shaft 102 and the driven shaft 103 are consistent, making the transportation smoother and more fluent.

[0033] The swinging nozzle 202 in the present device comprises a mounting seat 201, a nozzle 202, a driving device 203 and a reciprocating swing mechanism, wherein a plurality of nozzles 202 are arranged on the mounting seat 201, the driving device 203 is connected to the reciprocating swing mechanism, the reciprocating swing mechanism is connected to the mounting seat 201 to drive the mounting seat 201 to swing back and forth, wherein the driving device 203 is a servo motor, the reciprocating swing mechanism comprises a first driving gear 204, a first driven gear 205, a push rod 206 and a transmission plate 207, a rotating shaft 208 is arranged on both sides of the mounting seat 201, the driving device 203 is connected to the first driving gear 204 to drive the first driving gear 204 to rotate, the first driving gear 204 is meshed with the first driven gear 205, one end of the push rod 206 is eccentrically connected to the first driven gear 205, and the other end is hinged to one end of the transmission plate 207, and the end of the transmission plate 207 is fixedly connected to the rotating shaft 208. It also includes a bearing seat 210 and a bearing 209 . The bearing 209 is mounted on the bearing seat 210 . The rotating shaft 208 , the first driving gear 204 and the first driven gear 205 are rotatably connected to the bearing 209 respectively.

[0034] When transporting the building material template, the guide wheel 106 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 103, the driving shaft 102 and the transmission shaft clamp the building material template up and down and continue to transport the building material template in the working direction, which can not only avoid left and right displacement of the building material template, but also avoid the building material template from moving up and down due to the vibration of the machine itself during transportation. This transmission device can ensure that the building material template is smooth and stable during the transportation process, and avoid the phenomenon of the building material template being stuck. During the transportation of the building material template, the swinging nozzle 202 is started at the same time, the servo motor drives the first driving gear 204 to rotate, the first driving gear 204 drives the first driven gear 205 to rotate, the first driven gear 205 drives the push rod 206 eccentrically connected thereto to move, and the push rod 206 drives the transmission plate 207 to swing back and forth at a certain angle, thereby driving the swing of the mounting seat 201, realizing the change of the water spraying trajectory, realizing the reciprocating swinging water spraying, and washing the building material template back and forth. Among them, the swinging angle of the transmission plate 207 is set to 40°-50°, so that the water spray of the nozzle 202 can hit the surface of the building material template with a large pressure, and thus it can also prevent the high-pressure water sprayed by the nozzle 202 from deviating from the impact route to wash the position outside the building material template. In addition, the gear ratio of the first driving gear 204 and the second driving gear 104 used in this device can be adjusted according to the actual servo motor speed parameters and production requirements, so as to adjust and control the swing rate of the mounting seat 201. In addition, while keeping the gear ratio unchanged, a speed-regulating motor can be used as a driving device in order to more conveniently adjust and control the swing rate.

[0035] like Figure 4 As shown, in this embodiment, the mounting base 201 is installed in the middle of the frame 101, the nozzle 202 is arranged below the building material template, and the angle α between the length direction of the mounting base 201 and the length direction of the frame 101 is 100°-120°, wherein 110° is preferred. This setting makes the water spraying trajectory of the nozzle 202 not balanced with the frame 101, which is better than the water spraying trajectory of the nozzle 202 being balanced with the frame 101, and effectively improves the cleaning efficiency.

[0036] For details, please refer to Figure 5As shown, the dotted line is the water spray trajectory, the single-point line is the maximum forward distance and the maximum reverse distance of the water spray of the nozzle 202, the building material template moves in the direction shown in the figure, and the swinging nozzle 202 swings back and forth. Since there is an angle between the length direction of the mounting base 201 and the length direction of the frame 101, the water spray trajectory of the nozzle 202 forms an S-shaped water spray trajectory between the maximum forward spray distance and the maximum reverse spray distance of the nozzle 202. In this way, relative to the mounting base 201, it is vertically across the frame 101, which can have a larger flushing area and avoid repeated flushing of the same position to cause useless work. Therefore, the setting of the swinging nozzle 202 can effectively improve the cleaning efficiency.
