A municipal road curbstone construction device

Abstract

This invention discloses a municipal road curbstone construction device, including a pusher cart with an installation box fixedly mounted on its side. A control terminal is fixedly installed inside the installation box. This invention utilizes a separately mounted grinding device on the outside of a cooling and dust-removing roller to grind the surface of the curbstone. As the roller rotates, liquid is sprayed from inside the scattering holes, directly acting on the friction surface between the grinding device and the curbstone, achieving direct cooling. While stationary, water is stored in a water tank to cool the inside of the cooling and dust-removing roller. A dustproof device intercepts dust generated during grinding, which is then adsorbed by water jets from the remaining scattering holes, adhering to the inner wall of an arc-shaped plate. Finally, a filter plate filters the dust. Furthermore, the control terminal and photoelectric sensors automatically stop the device when the filter plate becomes clogged, causing the dustproof device to lose its dustproof effect, thus improving the overall automation level of the device.

Description

Technical Field

[0001] This invention relates to the field of curbstone grinding technology, specifically to a municipal road curbstone construction device. Background Technology

[0002] Curbstones, also known as kerb stones, are stones used to define road boundaries, guide traffic, and prevent vehicles from running off the road. These stones are typically installed on both sides of the road, serving both to protect and beautify it.

[0003] When repairing kerbstones during municipal construction, most surface maintenance currently involves workers using handheld cutting or grinding tools. Automated grinding systems are also used when the budget allows. However, during grinding, the grinding rollers and the kerbstone surface generate significant heat due to high-speed friction, with the temperature rising as the rotation speed increases. While existing systems typically use liquid cooling, this method prevents the liquid from directly penetrating the contact surface; it only absorbs heat by adhering to the surrounding area, resulting in a time lag and generally low cooling efficiency. At high temperatures, the kerbstone surface changes, becoming softer and potentially cracking, thus limiting the grinding roller's rotation speed and affecting the grinding rate. Furthermore, the grinding process generates a large amount of waste and dust. Currently, a separate spray nozzle is usually added for water mist dust removal, further increasing costs. Summary of the Invention

[0007] The cooling and dust removal roller has a water storage tank inside. The surface of the cooling and dust removal roller has scattering holes and slots. A square groove is formed in the middle of the scattering hole. Magnets are fixedly installed on both the left and right sides of the bottom of the square groove. A sliding block is fixedly installed inside the square groove. Magnets are fixedly installed on both the left and right ends of the sliding block. A water flow channel is formed on the surface of the sliding block. An isolation pad is fixedly installed on the top surface of both the left and right ends of the sliding block.

[0008] Preferably, the left end of the mounting plate is fixedly mounted on the outer wall of the mounting box, and the sleeve plate is movably sleeved inside the lifting groove.

[0009] Preferably, the right-angled end of the right-angle plate is at the same height as the photoelectric sensor at its highest position.

[0011] Preferably, the left end of the cooling and dust removal roller is provided with a connecting groove, which connects the cooling and dust removal roller, the connecting column, and the pulley through the inlet hole.

[0012] Preferably, the magnetic poles of the first magnet and the second magnet are opposite, the shape of the isolation pad is set as a triangular structure, and the size of the bottom end of the sliding block is adapted to the size of the scattering hole.

[0013] Preferably, the number of scattering holes and slots are the same, and both are distributed equidistantly along the polar axis of the cooling and dust removal roller on the outer wall of the cooling and dust removal roller through the center of the roller.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The surface of the curbstone is polished by a separate grinding device set on the outside of the cooling dust removal roller. As it rotates, liquid is sprayed out from the inside of the scattering hole, which directly acts on the friction surface of the grinding device and the curbstone to achieve direct cooling. At the same time, water is kept in the water storage tank in the static state to achieve cooling inside the cooling dust removal roller.

[0019] The dustproof device can intercept the dust generated during the grinding process, and then the water jets sprayed from the remaining scattering holes can adsorb the dust and make it adhere to the inner wall of the arc plate. Finally, the filter plate can be used for filtration. In addition, the control terminal and photoelectric sensors can be used to automatically stop the dustproof device when the filter plate is blocked and the dustproof effect fails, thus improving the overall automation level of the device.

[0020] The locking device effectively ensures the stability of the grinding device during rotation and friction. Furthermore, by using multiple grinding devices, individual damage to a specific area can be addressed and replaced separately. This facilitates operation, reduces costs, and improves the overall practicality of the device. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0033] like Figures 1 to 8As shown, a municipal road curbstone construction device according to a first aspect embodiment of the present invention includes a pusher 1, an installation box 2 fixedly installed on the side of the pusher 1, a control terminal 201 fixedly installed inside the installation box 2, a motor 3 electrically connected to the left end of the control terminal 201, a conveyor belt 4 provided on the output shaft of the motor 3, a pulley 5 provided inside the bottom end of the conveyor belt 4, a connecting column 502 fixedly installed on the inner end of the pulley 5, an inlet hole 501 provided inside both the pulley 5 and the connecting column 502, a locking device 6 fixedly installed on the outer wall of the connecting column 502, a cooling and dust removal roller 7 fixedly installed on the inner end of the connecting column 502, a slot 704 provided on the outer surface of the cooling and dust removal roller 7, a grinding device 9 detachably installed inside the slot 704, a photoelectric sensor 203 electrically connected to the right end of the control terminal 201, a lifting groove 202 provided inside the installation box 2, and a dustproof device 8 slidably installed inside the lifting groove 202.

[0034] The dustproof device 8 includes a mounting plate 801. A damping rod 802 is fixedly mounted on the top surface of the mounting plate 801. A right-angle plate 803 is fixedly mounted on the top of the damping rod 802. A sleeve plate 804 is fixedly mounted on the bottom left side of the right-angle plate 803. An arc-shaped plate 805 is fixedly mounted on both the left and right ends of the sleeve plate 804. A water collection trough 806 is formed on the inner wall of the arc-shaped plate 805. A diversion trough 807 is fixedly connected to the bottom of the water collection trough 806. A filter plate 808 is fixedly mounted on the bottom of the diversion trough 807. A collection frame plate 809 is fixedly mounted on the bottom of the inner wall of the arc-shaped plate 805.

[0035] The cooling and dust removal roller 7 has a water storage tank 702 inside. The surface of the cooling and dust removal roller 7 has scattering holes 703 and slots 704. A square groove 705 is formed in the middle of the scattering hole 703. Magnets 706 are fixedly installed on both the left and right sides of the bottom of the square groove 705. A sliding block 707 is fixedly installed inside the square groove 705. Magnets 708 are fixedly installed on both the left and right ends of the sliding block 707. A water flow channel 709 is formed on the surface of the sliding block 707. Isolation pads are fixedly installed on the top surfaces of both ends of the sliding block 707. 7010, the left end of the cooling dust removal roller 7 is provided with a connecting groove 701, the connecting groove 701 connects the cooling dust removal roller 7, the connecting column 502 and the pulley 5 through the inlet hole 501, the magnetic poles of the first magnet 706 and the second magnet 708 are opposite, the shape of the isolation pad 7010 is set as a triangular structure, the size of the bottom end of the sliding block 707 is adapted to the size of the scattering hole 703, the number of scattering holes 703 and the number of slots 704 are the same, and both are distributed on the outer wall of the cooling dust removal roller 7 at equal intervals through the center of the roller 7.

[0036] In the above embodiments, it should be noted that the inlet hole 501 can be connected to a water pipe and then to a corresponding water tank or water pump to ensure a continuous water supply inside the cooling and dust removal roller 7.

[0037] The technical effects achieved by the above embodiments are as follows: When the cooling and dust removal roller 7 rotates, it will drive the water flow inside the water storage tank 702 to apply centrifugal rotational force. After the speed reaches a certain level, the force increases and breaks through the magnetic force of the attraction between magnet 2 708 and magnet 1 706, causing the sliding block 707 to move to one end of the square groove 705 on the outer side. The scattering hole 703 is in a through state, and then the water flow is sprayed out from the inside to achieve precise spraying and cooling of the surface of the friction part, thereby improving the cooling efficiency. After the rotation stops, the sliding block 707 gradually attracts magnet 1 706 to close the connection of the scattering hole 703, so that the water storage tank 702 can store water inside and perform secondary cooling from the inside, thereby improving the cooling efficiency, extending the overall service life of the device, preventing the curbstone from overheating and deforming and cracking, and the efficient cooling can increase its rotation speed and improve the grinding efficiency. Example

[0038] like Figure 1 and Figure 4 As shown, in this embodiment, the left end of the mounting plate 801 is fixedly installed on the outer wall of the mounting box 2, the sleeve plate 804 is movably sleeved inside the lifting groove 202, the right-angle end of the right-angle plate 803 is level with the height of the photoelectric sensor 203 at the highest position, the number of the diversion groove 807 and the filter plate 808 is set to several, and the two correspond one to one with each other, and the inner wall of the arc plate 805 is coated with a waterproof coating.

[0039] The technical effect achieved by the above embodiment is as follows: When the cooling and dust removal roller 7 rotates, the internal water flow will be evenly sprayed out from the interior of multiple scattering holes 703. At this time, the water flow sprayed from the scattering holes 703 located in non-bottom positions will form more diffused water droplets as the rotation speed increases. Then, it will collide with the inner wall of the arc plate 805. The waterproof coating can make it form a secondary collision, causing it to break into more fine water droplets. This will aggravate the adhesion of dust generated by friction, and then enter the water collection tank 806, slide down from the interior of the diversion tank 807, and pass through the filter plate 808. Dust filtration is achieved by selecting an appropriate weight blockage through the damping rod 802. When the filter plate 808 becomes clogged, a mixture of water and dust gradually accumulates inside the collection frame plate 809. Eventually, the load on the connecting plate 804 increases, causing the right-angle plate 803 to move downwards. The photoelectric sensor 203 loses its target and transmits a signal to the control terminal 201, which controls the motor 3 to stop rotating, reminding the staff to clean it in time and ensuring the dustproof efficiency of the entire device. The arc plate 805 is used to better fit the angle of the water flow that is rotated and sprayed by centrifugal force, preventing water from splashing and affecting construction. Example

[0040] like Figure 9 and Figure 10 As shown, in this embodiment, the locking device 6 includes a fixing rod 601. A rotating wheel 602 is rotatably mounted inside the top end of the fixing rod 601. A stud 603 is fixedly mounted on the top end of the rotating wheel 602. A stop block 604 is threaded onto the surface of the stud 603. A sleeve rod 605 is fixedly mounted on the bottom end of the stop block 604. The bottom end of the fixing rod 601 is fixedly mounted on the surface of the connecting post 502. The sleeve rod 605 is movably sleeved inside the fixing rod 601. The grinding device 9 includes a clamping plate 901, a grinding roller body 902 is fixedly installed on the top of the clamping plate 901, and a semi-circular roller body 903 is fixedly installed on the side of the grinding roller body 902. The shape of the clamping plate 901 is adapted to the shape of the clamping groove 704. The top surface of the grinding roller body 902 is set as an arc surface structure, and the number of the arc surface corresponds to the number of the clamping groove 704. A gap is left between each two adjacent clamping plates 901 and semi-circular roller bodies 903, and the width of the gap corresponds to the width of the scattering hole 703.

[0041] The technical effects achieved by the above embodiments are as follows: the sleeve rod 605 can limit the movement of the stop block 604, allowing it to move uniaxially up and down, thereby moving to the side of the slot 704 to ensure that the card plate 901 will not slide out from the inside, thus applying a limiting and fixing effect. Finally, the semi-circular roller 903 can make it make an initial impact during the spraying process, breaking it up, increasing its adhesion surface area, and improving dust reduction efficiency.

[0042] Working principle: Connect the water pump and water pipe to the inside of the inlet hole 501, then inject liquid into the water storage tank 702. Then start the motor 3, which drives the pulley 5 to rotate via the conveyor belt 4. As the rotation speed increases, the centrifugal force of the sliding block 707 increases and overcomes the magnetic force of the attraction between magnet 2 708 and magnet 1 706, causing the sliding block 707 to move to one end of the square groove 705 on the outer side. The scattering hole 703 is then open, and water is sprayed out from the inside, spraying onto the friction surface for direct cooling. At this time, the water sprayed from the scattering hole 703, which is not at the bottom, will form more diffused water droplets as the rotation speed increases, and then collide with the surface. The water reaches the inner wall of the arc plate 805, where a waterproof coating allows it to undergo a secondary collision, breaking into more tiny water droplets. This causes the dust generated by friction to adhere more heavily, then enters the water collection tank 806 and slides down from inside the diversion tank 807. The dust is filtered by the filter plate 808, and the damping rod 802 selects an appropriate weight to block it. When the filter plate 808 is blocked, the water and dust mixture will gradually accumulate inside the collection frame plate 809. Finally, the load on the socket plate 804 increases, causing the right-angle plate 803 to move downward. The photoelectric sensor 203 loses its target and transmits a signal to the control terminal 201, which controls the motor 3 to stop rotating.

[0043] When the grinding roller 902 is worn out and needs to be replaced, rotate the wheel 602 to drive the stud 603 to rotate, causing the stop 604 to move down, opening the slot 704, then pull out the clamping plate 901 from inside, replace it with a new grinding roller 902 and insert it back into the original position, and finally reset the stop 604 to complete the clamping.
