Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a road surface cutting device with an automatic cleaning function for bridge construction. Background Art

[0002] In the process of bridge construction, pavement cutting is an important process. In the process of road construction, due to the low temperature in winter and the high temperature in summer, the pavement will expand and contract due to heat, which will cause damage to the pavement and reduce the service life of the pavement. Therefore, it is necessary to set up a pavement cutting device with automatic cleaning function for bridge construction to cut the pavement. However, the existing device still has certain use defects when used, such as:

[0003] Patent No. "CN201922049631.3" discloses a pavement cutting device for roads and bridges. When in use, the device can be easily moved through the mutual use of a base, a protective cover, a push handle and a universal wheel. When cutting, the assistant only needs to push the push handle to control the cutting direction, thereby reducing people's work pressure. However, when the device is in use, the universal wheel cannot fix the forward direction when cutting the pavement, which may cause the forward direction of the universal wheel to deviate when the staff pushes the device forward, requiring the staff to constantly adjust the forward direction, resulting in the cut slit to bend. Utility Model Content

[0004] The utility model aims to solve the above-mentioned problem and proposes a pavement cutting device with automatic cleaning function for bridge construction, which improves the problem that the existing pavement cutting device with automatic cleaning function for bridge construction is prone to bending.

[0005] A pavement seam cutting device with automatic cleaning function for bridge construction comprises a base, a shell, a support plate and a protective shell: the upper end of the base is provided with the shell, the upper end of the base is provided with the support plate, the side of the support plate is provided with the protective shell, and the interior of the protective shell is provided with a seam cutting structure;

[0006] The slitting structure comprises a second motor and a cutting blade. The second motor is arranged on the inner wall of the protective shell, and the cutting blade is arranged on the side of the second motor.

[0007] Preferably, a first roller is disposed at the lower end of the base, a universal wheel is disposed at the lower end of the base, and the protective shell passes through the base.

[0008] Preferably, a fixing block is provided on the side of the base, a hydraulic rod is provided at the upper end of the fixing block, the hydraulic rod passes through the fixing block, and a connecting block is provided at the lower end of the hydraulic rod.

[0009] Preferably, a second roller is disposed at the lower end of the connecting block, a first motor is disposed at the upper end of the outer shell, a threaded rod is disposed at the lower end of the first motor, and the threaded rod passes through the outer shell.

[0010] Preferably, a movable block is provided on the surface of the threaded rod, the movable block is threadedly connected to the threaded rod, and a sliding block is provided on the side of the protective shell.

[0011] Preferably, a water tank is provided at the upper end of the outer shell, a water pump is provided at the upper end of the outer shell, a telescopic water pipe is provided at the lower end of the water pump, and a nozzle is provided inside the protective shell.

[0012] Preferably, a storage battery is arranged at the upper end of the base, the sliding block is slidably connected to the support plate, and the sliding block is slidably connected to the housing.

[0013] The beneficial effects of the utility model are:

[0014] 1. Through the arrangement of the first roller, the second roller, the universal wheel, the hydraulic rod and the connecting block, when the device is in use, the universal wheel first contacts the first roller, and the universal wheel can adjust the forward direction to facilitate the device to turn and move. The universal wheel is smaller than the first roller, so the device moves in a forward tilted state. When the device moves to the position where the seam needs to be cut and the forward direction is adjusted, the hydraulic rod is opened and extended downward to push the connecting block downward, and the second roller is pushed downward through the connecting block to make the second roller contact with the ground, and the device is lifted to a horizontal position to prevent the universal wheel from contacting the ground. Because the first roller and the second roller cannot rotate, they can only move in the same direction, so that when the staff pushes the device forward, the device will not be offset, thereby preventing the cut seam from bending.

[0015] 2. Through the arrangement of the first motor, the threaded rod, the movable block and the protective shell, when the device is in use, by turning on the first motor, the first motor drives the threaded rod to rotate, so that the movable block moves downward on the surface of the threaded rod. At this time, the movable block drives the protective shell to move downward, and the cutting depth of the cutting blade on the road surface is adjusted through the protective shell, so that the device can adjust the cutting depth, thereby increasing the practicality of the device.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] When implementing: Figure 1-4 As shown, a pavement seam cutting device with automatic cleaning function for bridge construction includes a base 1, a shell 2, a support plate 13 and a protective shell 12: the upper end of the base 1 is provided with the shell 2, the upper end of the base 1 is provided with the support plate 13, the side of the support plate 13 is provided with the protective shell 12, and the interior of the protective shell 12 is provided with a seam cutting structure 22;

[0023] The slitting structure 22 includes a second motor 21 and a cutting blade 20. The second motor 21 is disposed on the inner wall of the protective shell 12, and the cutting blade 20 is disposed on the side of the second motor 21.

[0024] When the device is in use and needs to be cut, the second motor 21 is turned on to rotate, thereby driving the cutting blade 20 to rotate, so that the cutting blade 20 cuts the road surface. Then the staff pushes the device forward to make the cutting blade 20 cut the road surface.

[0025] A first roller 4 is disposed at the lower end of the base 1, a universal wheel 5 is disposed at the lower end of the base 1, and a protective shell 12 passes through the base 1;

[0026] A fixing block 3 is arranged on the side of the base 1, a hydraulic rod 7 is arranged on the upper end of the fixing block 3, the hydraulic rod 7 passes through the fixing block 3, and a connecting block 8 is arranged on the lower end of the hydraulic rod 7;

[0027] When the device is in use, first the universal wheel 5 contacts the ground with the first roller 4. At this time, the device is placed in an inclined state. The universal wheel 5 can be used to adjust the forward direction of the device, so that the staff can push the device to move it conveniently. Then the device is pushed to the position where the slit is required, and the forward direction is aligned with the direction where the slit is required. At this time, the hydraulic rod 7 is opened, so that the hydraulic rod 7 pushes the connecting block 8 to move downward, and the second roller 6 is pushed downward through the connecting block 8, so that the second roller 6 contacts the road surface, and the device is lifted up, and the universal wheel 5 is lifted to place the device horizontally. Because the first roller 4 and the second roller 6 cannot rotate, they can only move forward in one direction. At this time, the staff pushes the device forward, which can make the slit be cut straight to prevent the slit from bending.

[0028] A second roller 6 is disposed at the lower end of the connecting block 8, a first motor 9 is disposed at the upper end of the housing 2, a threaded rod 10 is disposed at the lower end of the first motor 9, and the threaded rod 10 penetrates the housing 2;

[0029] A movable block 11 is disposed on the surface of the threaded rod 10, and the movable block 11 is threadedly connected to the threaded rod 10, and a sliding block 14 is disposed on the side of the protective shell 12;

[0030] When the device is in use and the depth of the cutting seam needs to be adjusted, the first motor 9 is turned on to drive the threaded rod 10 to rotate, so that the movable block 11 moves downward on the surface of the threaded rod 10, and the protective shell 12 is driven downward by the movable block 11 to drive the cutting blade 20 to move downward, so as to adjust the cutting depth of the cutting blade 20 on the road surface.

[0031] A water tank 16 is disposed at the upper end of the housing 2, a water pump 17 is disposed at the upper end of the housing 2, a telescopic water pipe 18 is disposed at the lower end of the water pump 17, and a nozzle 19 is disposed inside the protective shell 12;

[0032] A battery 15 is disposed at the upper end of the base 1, a sliding block 14 is slidably connected to the support plate 13, and the sliding block 14 is slidably connected to the housing 2;

[0033] When the device is in use, after the cutting blade 20 generates a large amount of dust when cutting the road surface, the water pump 17 is turned on at this time, so that the water pump 17 draws the water in the water tank 16 into the telescopic water pipe 18, and then the water flow is sprayed out by the nozzle 19 to spray the water flow on the cutting point between the cutting blade 20 and the road surface to reduce the dust. Since the second motor 21 is a waterproof motor, it is not affected by the water flow. Moreover, through the setting of the protective shell 12, when the cutting blade 20 breaks and splashes, the broken blade can be blocked by the protective shell 12 to prevent the broken blade from flying upward and causing harm to the staff. In addition, the water sprayed by the nozzle 19 can also cool the cutting blade 20 to increase the service life of the cutting blade 20.

[0034] When the utility model is in use, the device is first pushed to the position where the slit is required through the universal wheel 5, so that the forward direction of the first roller 4 is aligned with the direction of the slit, and then the hydraulic rod 7 is opened to extend the hydraulic rod 7 downward, push the connecting block 8 to drive the second roller 6 to move downward, so that the second roller 6 contacts the ground and the device is pushed into a horizontal position, and then the second motor 21 is turned on, so that the second motor 21 drives the cutting blade 20 to rotate, and at this time, the first motor 9 is turned on, so that the first motor 9 drives the threaded rod 10 to rotate, and the movable block 11 is driven downward by the threaded rod 10, so that the movable block 11 drives the protective shell 12 to move downward, and the telescopic water pipe 18 is extended, and at this time, the protective shell 12 drives the cutting blade 20 to move downward, and the road surface is cut by the cutting blade 20, and then the water pump 17 is turned on, so that the water pump 17 draws the water inside the water tank 16 into the inside of the telescopic water pipe 18, and sprays the water flow to the slit through the nozzle 19 to reduce dust, and then the staff pushes the device forward to slit the road surface.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
