Description

Technical Field

[0001] This utility model belongs to the technical field of municipal road and civil aviation runway construction, specifically relating to a concrete slab joint cleaning machine. Background Technology

[0002] After cement concrete pavement is cut or pre-installed with expansion joints (expansion and contraction joints), in order to prevent damage to the expansion joints and to prevent rainwater, oil, and other contaminants from seeping into the roadbed through the expansion joints (expansion and contraction joints), which could lead to water accumulation, grouting, frost heave, and other phenomena in the lower pavement base layer and affect the quality of the base layer, it is necessary to perform joint sealing and waterproofing treatment. The most important step in the joint sealing process is to clean the debris inside the joint to ensure that the sealant is dense and has good durability.

[0003] The commonly used equipment for cleaning cracks in cement concrete pavements is the traditional handheld blower, which has a power of about 4.5kw. The blowing power is sufficient to remove ordinary dust and loose material. However, because the mud left in the cracks when the concrete is cut still has a certain strength after a period of time, it is embedded and attached to the bottom and side walls of the crack, making it impossible for the traditional blower to clean it completely. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a concrete slab joint cleaning machine that can be embedded in the joints for cleaning, and can complete the joint cleaning work efficiently and with high quality.

[0005] The embodiments of this application are implemented as follows:

[0006] This application provides a concrete slab joint cleaning machine, characterized in that it includes a support frame, a joint cleaning mechanism, and traveling wheels. The support frame includes a frame body and a handrail. The joint cleaning mechanism includes a drive device and a joint cleaning brush. The joint cleaning brush is installed at the center of the bottom front end of the frame body. The drive device is installed on the upper part of the frame body. The traveling wheels are installed at the center of the bottom rear end of the frame body.

[0007] In some alternative implementations, the seam sweeping brush is connected to the frame via bearings and a rotating shaft, and the driving device is a drive motor connected to the rotating shaft to drive the seam sweeping brush to rotate.

[0008] In some alternative implementations, the crevice brush includes a brush disc and brush strips, the brush strips being fixed at uniform intervals along the circumference of the brush disc.

[0009] In some alternative implementations, the bottom of the frame is provided with an embedded wheel, the embedded wheel including a wheel body and an embedded ring bar, the embedded ring bar being arranged around the center of the circumference of the wheel body, and the line shape is consistent with the seam shape.

[0010] In some alternative implementations, the bottom of the frame is provided with auxiliary wheel sets, which are symmetrically installed on both sides of the frame axis.

[0011] In some alternative implementations, the brush plate is fixed by bolts to two symmetrically arranged circular iron plates, and the brush strip is fixed in the gap between the two circular iron plates.

[0012] In some alternative embodiments, the wheel body of the embedded wheel is a stone wheel, and the embedded ring is a steel ring.

[0013] In some alternative implementations, the brush bar is a steel wire rope, with the folded end of the steel wire rope embedded in the brush disc, and both ends of the steel wire rope exposed and dispersed in the shape of a steel wire brush.

[0014] In some alternative implementations, a vacuum cleaner is mounted on the frame, located behind the wire brush.

[0015] In some alternative implementations, the frame is also provided with a power supply device that is electrically connected to the drive motor for power supply.

[0016] The beneficial effects of this application are: 1. The concrete slab joint cleaning machine provided by this application has a joint cleaning brush embedded in the joint and rotating. The wire brush rotates rapidly and comes into contact with the strong mud, thereby brushing off the mud and carrying it out of the joint, which greatly improves the work efficiency. The working principle of the equipment is simple, the operation is convenient and easy to master, and the construction safety is high. 2. By matching the embedded wheel with the joint shape, there is no need to manually control the line shape, which can achieve precise control of the joint cleaning quality. The auxiliary support of the auxiliary wheel enhances the construction stability of the joint cleaning machine and has high safety performance. Attached Figure Description

[0022] It should be understood that the sequence number of each step in the embodiment does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] The features and performance of this application will be further described in detail below with reference to the embodiments.

[0025] like Figure 1 As shown, a concrete slab joint cleaning machine includes a support frame 1, a joint cleaning mechanism, and a traveling wheel 2. The support frame includes a frame body and a handrail. The joint cleaning mechanism includes a drive device 3 and a joint cleaning brush 4. The joint cleaning brush is installed at the bottom center of the front end of the frame body, the drive device is installed on the upper part of the frame body, and the traveling wheel is installed at the bottom center of the rear end of the frame body.

[0026] The seam sweeping brush is connected to the frame via bearings and a rotating shaft. The drive mechanism is connected to the rotating shaft, which drives the seam sweeping brush to rotate. In use, the operator holds the handle and pushes the seam sweeping machine to move. The seam sweeping brush comes into direct contact with the seams to be cleaned, and removes debris from the seams through rotation.

[0027] The seam brush includes a brush disc 41 and brush strips 42, with the brush strips fixed at even intervals along the circumference of the brush disc. The brush disc is fixed by bolts connecting two symmetrically arranged circular iron plates, and the brush strips are fixed in the gap between the two circular iron plates. The brush strips can be steel wire ropes, with the folded ends of the steel wire ropes embedded in the brush disc, and both ends of the steel wire ropes exposed and spread out in a steel wire brush shape. Different specifications of steel wire ropes are installed according to the seam width.

[0028] Furthermore, auxiliary wheel sets 5 are provided at the bottom of the frame, which are symmetrically installed on both sides of the frame axis to ensure the stability of the sewing machine during its movement.

[0029] Furthermore, a power supply device 6 is also provided on the frame, which is electrically connected to the drive motor for power supply.

[0030] Example 1

[0031] In this embodiment, the bottom of the frame is provided with an embedded wheel 7, which includes a wheel body 71 and an embedded ring 72 (see...). Figure 2 The embedded ring is wrapped around the center of the circumference of the wheel body, and the line shape is consistent with the seam shape.

[0032] The embedded wheel is made of stone, providing good stability. The embedded ring is made of steel, and its width and depth are determined based on the width and depth of the cut (width is 80% of the cut width, and depth is generally 2cm), ensuring that the embedded wheel moves within the cut. The embedded wheel's movement within the cut eliminates the need for manual control of its trajectory, allowing for precise control of the cut quality and ensuring the accuracy of the cut cleaning machine.

[0033] Example 2

[0034] In this implementation plan, a vacuum cleaner 8 is installed on the frame, located behind the wire brush. It can suck out the mud and foam in the gap, ensuring that the gap is cleaned of debris and particles.

[0035] In practical use, the process is as follows:

[0036] When the seam sweeping switch is turned on, starting the drive motor allows the brush disc and brush strips to rotate evenly, enabling seam sweeping. As the worker pushes the seam sweeping machine forward slowly at a constant speed, the wire brush removes the slurry from the seams. The brush disc rotates clockwise to prevent debris from being blown back into the equipment and causing secondary pollution. For areas with high slurry strength, the drive motor speed can be increased to enhance rotational power, ensuring that all slurry is completely brushed off and removed from the seams. When the vacuum cleaner switch is turned on, the vacuum cleaner located at the end of the equipment begins operation. The vacuum cleaner collection bucket is connected to a PVC pipe, with the inlet at a 30°~45° angle to the ground, sucking out slurry and debris from the seams. Record the speed adjustment parameters for future seam sweeping operations.

[0037] After the preparation work is completed, the crack cleaning work begins. During the process of pushing the crack cleaning machine, it is moved forward at a constant speed according to the speed obtained from the test, and a special person is arranged to observe from behind to check whether the wire brush has completely brushed off the mud in the crack to ensure that the quality meets the requirements of subsequent crack filling construction.
