Description

Technical Field

[0001] The invention relates to the field of bridge construction, and more specifically to a surface cleaning and spraying device for road and bridge construction. Background Art

[0002] Roads and bridges are generally composed of several parts, such as roadbed, pavement, bridges, tunnel projects and traffic engineering facilities. During the construction process, the surface of roads and bridges will be sprayed according to actual needs. Common spraying devices require manual cleaning of the surface of the road and bridge where spraying is required before spraying to ensure the cleanliness of the spraying position on the road and bridge surface. This method increases the labor burden, and the cleaning efficiency is low, takes a long time, and affects the progress of the spraying construction work.

[0003] The existing surface spraying device for road and bridge construction can clean the road and bridge surface through a dust suction component or an air jet component to ensure the cleanliness of the surface during spraying and improve the construction quality. However, during the design and use of such devices, it is easy for a variety of garbage and obstacles to exist on the surface of roads and bridges, especially on larger bridge roads. Due to the large span of the bridge, there are fewer pedestrians on the bridge deck, most of whom are vehicles, and it is rare for pedestrians or drivers to stop to clear obstacles. In addition, due to the high cost of manual cleaning of bridge roads and the low cleaning frequency, the reciprocating rolling of vehicles causes larger particles of garbage and obstacles to be easily retained in the area that needs to be sprayed. It is difficult for the dust suction component or jet component of such devices to clean most of the garbage and obstacles on the surface of roads and bridges. For example, it is difficult for such devices to clean larger obstacles and garbage such as larger wooden strips, gravel, and stones. Moreover, dust suction devices are prone to blockage or damage to dust suction components. In complex situations such as bridge decks, the internal dust suction box also needs to be cleaned in time by the operator, and the maintenance frequency is high. In addition, it is not convenient for such devices to adjust and fix the spray position of the spray head. When spraying on both sides of roads and bridges, the device is difficult to perform.

[0004] Therefore, a surface cleaning and spraying device for road and bridge construction is proposed. Summary of the invention

[0022] like Figure 1-3 and Figure 7 As shown, the adjustment unit 9 includes a slide groove 901 opened on the upper surface of the vehicle body 1 and located below the screw seat 3, four pulleys 902 are fixedly connected to the lower surface of the screw seat 3, the interior of the screw seat 3 extends to the upper surface and is rotatably connected to a one-way screw 903, and the one-way screw 903 is driven by an upper end motor, the outer cylindrical surface of the one-way screw 903 is threadedly connected to a first nut seat 904, and the lifting frame 5 is fixedly connected to the front surface of the first nut seat 904, a vertical groove 905 is opened on the rear surface of the lifting frame 5, a transverse groove 906 is opened on the front surface of the vehicle body 1, and balls 907 are rollingly connected inside the vertical groove 905 and the transverse groove 906, an auxiliary locking mechanism 908 is arranged between the screw seat 3 and the body 4, and the motor at the upper end of the one-way screw 903 is a self-locking reduction motor.

[0023] like Figure 1 , Figure 2 As shown, the auxiliary locking mechanism 908 includes a limiting slide 9081 fixedly connected to the upper surface of the vehicle body 1 and located between the screw seat 3 and the machine body 4, a first sliding sleeve 9082 is fixedly connected to the rear surface of the screw seat 3, and the upper surface of the first sliding sleeve 9082 extends to the upper surface of the limiting slide 9081 and is threadedly connected to the first locking bolt 9083.

[0024] like Figure 1 , Figure 3 - Figure 6 As shown, the disassembly unit 13 includes a fixing rod 131 fixedly connected to the rear side of the upper surface of the obstacle removal plate 12, two screw hole plates 132 are fixedly connected to the outer surface of the swivel seat 6, and the fixing rod 131 is fixedly connected to the surface of the screw hole plate 132 on one side by bolts, the front end of the output shaft of the transmission motor 7 is fixedly connected with a special-shaped bearing 133, and the outer cylindrical surface of the special-shaped bearing 133 is fixedly connected with a limiting block, the front surface of the obstacle removal plate 12 is rotatably connected with a buckle rod 134, and the front surface of the obstacle removal plate 12 is fixedly connected with an anti-rotation block 135 at the surface where the buckle rod 134 fits the front surface of the obstacle removal plate 12. The installation position of the obstacle removal plate 12 can be selected according to actual conditions.

[0025] By adopting the above technical scheme, when the device is used for cleaning during the spraying process, the spring latch 10 can be pulled upwards, the rotating seat 6 can be rotated, and the cleaning brush roller 8 can be adjusted to a suitable tilt angle, so that when the vehicle body 1 is moving forward, the cleaning brush roller 8 can clean the range sprayed by the spray head. When cleaning, turn on the transmission motor 7, and the transmission motor 7 can drive the cleaning brush roller 8 to move forward to clean the garbage on the surface of the road bridge, so that most of the garbage in the forward range is moved to one side of the spraying range. The cleaning range can also be adjusted by adjusting the tilt angle of the cleaning brush roller 8. For obstacles that are difficult to clean, such as large wooden strips, gravel, and stones, the obstacle removal plate 12 will push such obstacles and gradually discharge them to one side of the spraying range, and they will be cleaned uniformly by special cleaning personnel or equipment later. When it is necessary to change the side for spraying, in addition to changing the side of the spray head of the machine body 4, the first locking bolt 9083 can be loosened to slide the screw seat 3 to the other side of the vehicle body 1. During the sliding process, the pulley 902 can roll inside the slide groove 901 to reduce the friction resistance. At the same time, the ball 907 can roll inside the horizontal groove 906 to provide support force while reducing resistance. By controlling the motor to drive the one-way screw rod 903 to rotate, the cleaning roller 8 and the obstacle removal plate 12 can be controlled to rise and fall to better fit the surface of the road bridge. During the lifting process, the ball 907 can roll inside the vertical groove 905. After changing sides, the transmission motor 7 can rotate in the opposite direction to achieve the forward shifting effect. At this time, it is necessary to use the disassembly unit 13 to install the obstacle removal plate 12 on the screw hole plate 132 on the other side of the swivel seat 6 to achieve a better obstacle removal effect. When installing the obstacle removal plate 12, the buckle rod 134 is first buckled on the outer cylindrical surface of the special-shaped bearing 133, and the anti-rotation block 135 can limit the rotation of the buckle rod 134 without hindering the side changing function, and then the fixing rod 131 is fixedly connected to the screw hole plate 132 by bolts.

[0026] like Figure 4 - Figure 5 As shown, the outer circumferential surface at the rear end of the output shaft of the transmission motor 7 is fixedly connected to a limit plate 14, the front surface of the limit plate 14 is located at the outer circumferential surface of the output shaft of the transmission motor 7 and is fixedly connected to two clamping blocks 15, a clamping groove 16 is penetrated through the inner circumferential surface of the brush roller 8, and the outer circumferential surface of the output shaft of the transmission motor 7 is located at the rear side of the special-shaped bearing 133 and is threadedly connected to an anti-slip nut 17.

[0027] By adopting the above technical solution, if the cleaning brush roller 8 reaches the replacement standard after long-term use, the anti-drop nut 17 can be unscrewed, the worn cleaning brush roller 8 can be removed, and the cleaning brush roller 8 that meets the standard can be replaced. During installation, the block 15 is connected to the inside of the slot 16 to achieve a better transmission effect. Implementation:2:

[0028] like Figure 7 - Figure 8As shown, a sleeve 18 is fixedly connected to the middle position of the lower surface of the vehicle body 1, and the outer surfaces of both ends of the sleeve 18 extend to the inner surfaces and are threadedly connected to the second locking bolts 19.

The spray head of the body 4 is clamped and fixed to the inside of the fixing frame 22 by a locking screw. Two baffles 23 are provided below the fixing frame 22, and an adjustment mechanism 24 is provided on the outside of the hanging plate 21.

[0029] like Figure 8-9 As shown, the adjustment mechanism 24 includes a second sliding sleeve 241 fixedly connected to the upper side of the outer surface of one side of the hanging plate 21, and the second sliding sleeve 241 can slide on the outer cylindrical surface of the extension frame 20, the rear surface of the second sliding sleeve 241 extends to the outer cylindrical surface of the extension frame 20 and is threadedly connected with a third locking bolt 242, one side surface of the fixed frame 22 passes through the hanging plate 21 and is fixedly connected with a fixing screw 243, and the surface of the hanging plate 21 is provided with an insertion hole for the fixing screw 243 to pass through, one end of the fixing screw 243 is threadedly connected with a fastening nut 244 on the outer cylindrical surface, and the outer cylindrical surface of the fixing screw 243 is provided with a distance adjustment mechanism 245.

[0030] like Fig. 9 - Fig.10 As shown, the distance adjustment mechanism 245 includes a fixing plate 2451 arranged on the outer circumferential surface of the fixing screw 243, and a plurality of alignment holes 2452 are opened through the surface of the fixing plate 2451. The outer surfaces on both sides of the fixing plate 2451 are fixedly connected with cross bars 2453, and the cross bars 2453 can be inserted into the insertion holes of the baffle plate 23. The upper surface of the baffle plate 23 extends to the insertion holes and is threadedly connected with fastening screws 2454.

[0031] By adopting the above technical scheme, the sleeve 18 and the extension frame 20 can be well extended and fixed while being able to fit the cleaning brush roller 8 to perform side changing operations. When adjusting and fixing the extension length of the extension frame 20, the second locking bolt 19 can be turned, and when adjusting and fixing the height of the second sliding sleeve 241, the third locking bolt 242 can be turned. When adjusting and fixing the spraying angle of the spray head of the body 4, the fastening nut 244 can be turned. The baffle 23 can block the places that do not need to be sprayed during the spraying process of the spray head, thereby improving the spraying effect. By inserting the fixing screw 243 into the appropriate alignment hole 2452 on the fixing plate 2451, the blocking height of the baffle 23 can be appropriately adjusted, and the spacing between the two baffles 23 can be adjusted and fixed by turning the fastening screw 2454.

[0034] By adopting the above technical solution, when the pigment liquid level inside the raw material barrel 2 gradually decreases, the float 27 will also gradually decrease with the liquid level. The operator can judge the amount of pigment inside the raw material barrel 2 according to the descending position of the measuring rod 25. When the raw material barrel 2 is placed on the vehicle body 1, the bidirectional screw 29 on the fixed seat 28 can be rotated by a hand wheel to allow the two second nut seats 30 and the clamping arm 31 to approach, so as to support the raw material barrel 2 and prevent it from tipping over.

[0035] Instructions for use: The operator can adjust the inclination angle and working position of the cleaning roller 8 according to actual use requirements. When it is necessary to clean and spray the left or right side of the vehicle body 1, the adjustment unit 9 can be used to change the direction. The disassembly unit 13 can change the side of the obstacle removal plate 12. The fixing method of the sleeve 18 and the adjustment mechanism 24 can adjust the working position of the spray head at will. The distance adjustment mechanism 245 can easily adjust the distance between the baffles 23. The operator can determine the amount of paint inside the raw material barrel 2 based on the float 27. When the paint barrel 2 is placed on the upper surface of the vehicle body 1, the operator can use the clamping arm 31 to prevent the raw material barrel 2 from tipping over.
