Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of pavement concrete joint cleaning, especially relates to a pavement concrete joint cleaning device for joint filling. BACKGROUND

[0002] In the pavement construction process, in order to avoid the cracking of large area pavement under thermal expansion and cold contraction, the pavement needs to be jointed in the current construction process, and the joint is used to provide a buffer space for the thermal expansion and cold contraction of the concrete pavement. In the actual construction process, the joint on the pavement often needs to be cleaned, and after cleaning, joint filler needs to be filled into the joint. By filling the joint filler, a large amount of sewage can be prevented from entering the concrete structure layer along the joint, thereby reducing the service life of the concrete pavement.

[0003] Specifically, because the joint filler has high sealing property and certain elastic deformation capacity, it not only has a sealing effect, but also cooperates with the thermal expansion and cold contraction of the concrete pavement. However, the service life of the joint filler has a certain limit, so it needs to be cleaned regularly and new joint filler needs to be filled in the actual production process.

[0004] Because the length of the pavement is relatively large, the traditional manual joint cleaning method is not only low in joint cleaning efficiency, but also causes the joint to be difficult to clean because hard objects such as stones are easily stuck in the joint during the joint cleaning process. UTILITY MODEL CONTENTS

[0005] Based on the above background, the purpose of the utility model is to provide a pavement concrete joint filling joint cleaning device.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0025] The utility model has the following beneficial effects:

[0026] 1、In the working process, the air blowing structure adjusts the height through the height adjusting structure. When the amount of dirt in the gap is relatively large, the air blowing force is increased by reducing the distance between the air blowing pipe and the gap, thereby improving the air blowing effect on the dirt in the gap. Specifically, the height adjusting structure includes a mounting base fixedly installed at the top of the frame, two adjusting screws are fixedly connected to the top of the mounting base, the adjusting screws are slidably connected with mounting arms, and the upper ends of the mounting arms are fixedly installed on the air blower; a pair of adjusting nuts are threadedly connected to the adjusting screws and positioned on the mounting arms.

[0039] Example 1

[0040] like Figures 1-5 As shown, a crack-cleaning device for grouting concrete pavement includes a crack-cleaning mechanism. The crack-cleaning mechanism includes a traveling trolley, similar to existing traveling trolleys. The main structure of the traveling trolley includes a frame 1, on which several traveling wheel structures are mounted. Specifically, a pair of traveling wheel structures spaced apart on the front and rear side walls of the frame 1 are respectively mounted, similar to existing traveling wheel structures. Each traveling wheel structure includes a wheel seat 111 fixedly mounted on the frame 1, on which a traveling wheel 11 is mounted. A traveling wheel motor 12 for driving the traveling wheel 11 to rotate is mounted at the bottom of the frame 1. The output shaft of the traveling wheel motor 12 is fixedly mounted on the traveling wheel 11.

[0041] During the seam cleaning process, the traveling trolley moves along the seam with a relatively long length to clean the seam, thereby increasing the seam cleaning efficiency.

[0042] An air-blowing structure is installed on the top left side of the aforementioned traveling trolley, and a slit structure is installed on the bottom right side of the traveling trolley.

[0043] Specifically, the air-blowing structure includes a blower 2 and an air-blowing pipe 21 installed at the air outlet of the blower 2. The air-blowing pipe 21 has a conical shape, designed to obtain greater air pressure after the airflow exits from the air-blowing pipe 21, thereby increasing the blowing force on dirt in the crevices. The aforementioned air-blowing pipe 21 is inclined downwards.

[0044] During operation, the trolley travels along the gap and the gap is cleaned by air blowing through the air blowing structure.

[0045] During operation, the air blowing structure is height-adjustable via a height adjustment structure 22 to adjust the air blowing force. For example, if there is a large amount of dirt in the gap, the air blowing force can be increased by reducing the distance between the air blowing pipe 21 and the gap, thus improving the air blowing effect on the dirt in the gap. Specifically, the height adjustment structure 22 includes a mounting base 223 fixedly installed at the top of the frame 1. Adjusting screws 222 are fixedly connected to both sides of the top of the mounting base 223. Mounting arms 221 are slidably connected to the adjusting screws 222, and the upper ends of the mounting arms 221 are fixedly installed on the blower 2. A pair of adjusting nuts positioned on the mounting arms 221 are threaded onto the adjusting screws 222.

[0046] During operation, the operator loosens the adjusting nut and raises or lowers the blower 2. During this process, the mounting arm 221 slides relative to the adjusting screw 222 for adjustment, and then is repositioned by adjusting the nut.

[0047] Example 2

[0048] like Figures 1-5 As shown, this embodiment, based on the structure of embodiment 1, includes a cutting bracket 31. A cutting wheel 32 (similar to existing cutting wheels, but with several integrally formed serrated structures for use during operation under the drive of a motor) is mounted on the cutting bracket 31. A motor 33 (similar to existing methods, the cutting bracket 31 is fixedly mounted on the top of the motor 33) is also mounted on the cutting bracket 31 to drive the cutting wheel 32 to rotate. During operation, the cutting wheel 32 rotates at high speed under the drive of the motor 33, cutting and breaking up dirt such as gravel stuck in the gap, facilitating cleaning.

[0049] The kerfing structure described above adjusts the kerfing depth of the kerfing wheel 32 via an adjustment mechanism. Specifically, the adjustment mechanism includes a pair of electric push rods 34 (wherein, the electric push rods 34 are conventional electric telescopic rods disclosed in the prior art), and the pushing end of the electric push rods 34 is fixedly installed at the top edge of the cutting bracket 31.

[0050] Meanwhile, in the existing manner, the top of the electric push rod 34 is fixedly mounted on the top of the frame 1 by a mounting bracket 341.

[0051] A spring sliding structure 35, which is slidably connected to the frame 1, is fixedly connected to the top center position of the cutting bracket 31. The spring sliding structure 35 includes a slide rod fixedly connected to the top center position of the cutting bracket 31. The slide rod is slidably connected to the frame 1. A spring is sleeved on the slide rod. A spring seat is fixedly connected to the top of the slide rod. The two ends of the spring are respectively fixedly connected to the spring seat and the top of the frame 1.

[0052] During operation, driven by the electric push rod 34, the cutting bracket 31 descends. At this time, the cutting wheel 32 penetrates deeper into the gap. During this process, the slide bar slides relative to the frame 1 while the spring is stretched. This method allows for adjusting the cutting depth according to the gap depth. Simultaneously, this method also allows for adjusting the cutting depth based on the density of the debris filling the gap. If the filling is dense, the cutting wheel 32 is lowered to make the cut.

[0053] Example 3

[0054] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 2, a slotting structure is installed at the center of the bottom of the aforementioned traveling trolley. The slotting structure engages with the cutting wheel 32 to further remove the shredded filler from the gaps, enhancing the air-blowing effect.

[0055] Specifically, a hinge interface is provided on the top of the frame 1, and a hinge screw 411 is fixedly connected to the frame 1. The rotating arm 41 is fixedly connected to the hinge screw 411. Nuts are threaded onto both ends of the hinge screw 411. During operation, the operator flips the rotating arm 41 to adjust the angle at which the slotting hook penetrates into the gap.

[0056] Meanwhile, the above-mentioned slotting structure includes a hinged rotating arm 41, and a slotting hook 43 (the slotting hook 43 is in the shape of a hook) is installed at the bottom of the rotating arm 41.

[0057] Specifically, the bottom of the rotating arm 41 is threadedly connected to a length adjusting screw 42 (a threaded cavity of a certain depth is opened on the rotating arm 41), and the slotting hook 43 is fixedly connected to the length adjusting screw 42.

[0058] During operation, the distance between the slotting hook 43 and the gap can be adjusted by rotating the length adjusting screw 42, which makes it easier to adjust the depth to which the slotting hook 43 penetrates into the gap.

[0059] The hinge interface is threaded with clamping screws 44 on both sides, which abut against the rotating arm 41 (the threads of the clamping screws 44 have a certain depth and can be adjusted to the clamping state according to the rotation angle of the rotating arm). During operation, after the operator rotates the rotating arm 41 to adjust the angle of the slotting hook 43, the clamping screws 44 on both sides abut against the rotating arm 41 to position the rotating arm 41. During the movement of the trolley, the slotting hook 43 can fully loosen and remove the debris filling the cut gaps for easy air blowing cleaning.

[0060] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
