Description

Technical Field

[0001] The invention relates to the technical field of road edge finishing, in particular to a device for grinding uneven areas of road edge. Background Art

[0002] With the development of society and the increase in vehicles, the scope of road paving is constantly expanding, and there are more and more cement roads. When paving cement roads, corresponding templates are usually required to position both sides of the cement roads in order to form cement roads of specified widths. Due to the existence of templates, uneven bumps are prone to appear at the edges of the road surface. In order to improve the flatness of the road, corresponding grinding equipment is usually required for grinding.

[0003] After searching, the Chinese invention patent with publication number CN116397498B discloses a grinding device for uneven areas on the edge of a road surface. The grinding mechanism drives the grinding cylinder and the grinding disk to rotate, and grinds the bottom surface and the vertical surface of the edge of the road surface. The flatness of the road surface is sensed in advance by the guide mechanism, so that the driving cylinder is adjusted to avoid the grinding cylinder and the grinding disk directly colliding with the raised position. The driving cylinder is pushed by the pushing mechanism to achieve the purpose of automatic resistance pushing grinding, and the pushing automatically stops after the grinding is completed, and the dust generated by the grinding is collected by the collecting mechanism.

[0004] During use of the above-mentioned grinding device for uneven road edge areas, the equipment is pushed forward by two sets of rollers arranged under the body. It is necessary to ensure that the equipment moves along the edge trajectory, and then the uneven edge areas can be ground in conjunction with the rotating grinding cylinder and grinding disc. However, during the advancement of the equipment, the equipment lacks a guiding function, so that when the staff pushes the equipment, its movement trajectory is prone to deviation from the edge trajectory, resulting in the grinding mechanism being unable to contact the uneven edge area, affecting its grinding effect. In addition, when the side of the road surface is not at the same height as the original road surface, such as a bridge road surface, when the staff pushes the equipment along the edge trajectory, the equipment is prone to imbalance, which in turn leads to rollover. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention provides a grinding device for uneven road edge areas. By setting the adjusting parts in the auxiliary components, the angle of the auxiliary wheels can be adjusted horizontally or vertically. By the auxiliary wheels in a horizontal state walking on the road surface, the balance of the movement of the equipment can be improved. By setting the auxiliary wheels in a vertical state, the equipment can roll on the side walls of the road surface. The grinding device walking along the edge of the road surface can be guided, thereby improving the grinding effect of the uneven road edge area. This solves the problem that the grinding device in the prior art lacks the function of guiding the motion trajectory when grinding the uneven road edge area, so that when the grinding device is pushed forward, the motion trajectory of the grinding device is prone to deviation from the edge trajectory, thereby affecting the grinding effect.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides a grinding device for uneven road edge areas, which has the following beneficial effects:

[0024] 1. The present invention is used for grinding uneven road surface areas through the setting of a grinding mechanism. The angle of the auxiliary wheel can be adjusted horizontally or vertically through the setting of an adjusting part in the auxiliary component. The auxiliary wheel in a horizontal state moves on the road surface, which can further improve the balance of the movement of the equipment and prevent it from tipping over. The auxiliary wheel in a vertical state can roll on the side wall of the road surface, and the grinding device moving along the edge of the road surface can be guided, thereby improving the grinding effect of the uneven edge area. This solves the problem that the grinding device in the prior art lacks the function of guiding the motion trajectory when grinding the uneven edge area of ​​the road surface, so that when the grinding device is pushed forward, its motion trajectory is prone to deviation from the edge trajectory, affecting its grinding effect.

[0025] 2. The present invention can drive the adjustment plate to move up and down by rotating the transmission shaft. The up and down movement of the adjustment plate can adjust the initial position of the spring, indirectly controlling the squeezing force of the spring on the telescopic shaft, thereby satisfying the different contact forces between the grinding disc and the protrusions in the uneven area of ​​the road edge. This not only avoids the problem of the grinding disc being easily damaged due to long-term work when the contact force of the grinding disc is large, but also avoids the problem of the grinding disc being unable to effectively and quickly process the protrusions in the uneven area when the contact force of the grinding disc is small, thereby improving the grinding processing effect.

[0026] 3. The present invention can drive the driving shaft to move up and down through the setting of the electric telescopic rod, and then drive the piston plate to reciprocate up and down. Through the up and down movement of the piston plate, not only can the dust gas generated during the grinding process be extracted through the absorption part, but the extracted dust gas can also be purified through the purification part at the same time. It has a good linkage function, which not only improves the energy saving and environmental protection of the equipment, but also improves the treatment effect of dust in the gas, and solves the problem that the prior art generally uses a single filter screen method or a water spray method, and the filtering effect is poor and easy to be blocked when it is processed through the filter screen, and the problem that when it is processed by the water spray method, the water source demand is large.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] See attached Figure 1-9, a grinding device for uneven road edge area, comprising a housing 1 and a driving handle fixed to the back of the housing 1, and a control system 2 is installed on the driving handle, the bottom of the housing 1 is rotatably connected to two groups of rollers 3 through a bracket, a grinding mechanism 4 is arranged at the front end of the housing 1, a processing mechanism 5 for processing dust gas during grinding is arranged inside the housing 1, and an auxiliary component 6 is arranged on one side or both sides of the housing 1;

[0044] The control system 2 adopts the electric control mechanism in the prior art, which is used to electrically control the grinding device. The two sets of rollers 3 are arranged to facilitate the grinding device to walk on the road surface and improve its walking balance. The grinding mechanism 4 is arranged to grind the uneven road surface area. The processing mechanism 5 is arranged to process the dust gas generated by the road surface grinding process. The auxiliary component 6 is arranged to improve the guiding property of the grinding device walking on the edge of the road surface.

[0045] The grinding mechanism 4 includes a grinding cover 41, a grinding disc 42 disposed inside the grinding cover 41, and a motor 43 for rotating the grinding disc 42;

[0046] The grinding cover 41 is used to protect the grinding disc 42 during the rotation process, and the motor 43 is used to drive the grinding disc 42 to rotate. The grinding disc 42 during the rotation process can grind the uneven road surface.

[0047] The processing mechanism 5 includes an absorber for absorbing dust gas during grinding and a purifier for purifying the absorbed dust gas;

[0048] The absorber in the processing mechanism 5 is used to absorb the dust gas during the grinding process, and the purification member is used to purify the absorbed dust gas to improve the quality of the working environment.

[0049] The auxiliary assembly 6 includes an auxiliary wheel 61 for rolling on the top of the road surface or the side wall of the road surface, and an adjusting member for vertically adjusting the auxiliary wheel 61 in a horizontal state or horizontally adjusting the auxiliary wheel 61 in a vertical state;

[0050] By setting the auxiliary wheel 61 in the auxiliary assembly 6, the grinding device walking on the road surface can be guided to ensure the balance of its grinding movement;

[0051] By setting the adjustment parts in the auxiliary component 6, the angle of the auxiliary wheel 61 can be adjusted horizontally or vertically. By the auxiliary wheel 61 in a horizontal state walking on the road surface, the balance of the movement of the equipment can be further improved to prevent it from tipping over. By setting the auxiliary wheel 61 in a vertical state, it can roll on the side wall of the road surface, and the grinding device walking along the edge of the road surface can be guided, thereby improving the grinding effect of the uneven edge area. This solves the problem that the grinding device in the prior art lacks the function of guiding the motion trajectory when grinding the uneven edge area of ​​the road surface, so that when the grinding device is pushed forward, its motion trajectory is prone to deviation from the edge trajectory, affecting its grinding effect.

[0052] See attached Figure 3 and Figure 5 , both ends of the auxiliary wheel 61 are rotatably connected to a connecting block 62, and the interiors of the two connecting blocks 62 are rotatably connected to a connecting shaft 63, and a U-shaped frame 64 is rotatably connected between the two ends of one connecting shaft 63, and the U-shaped frame 64 is fixedly connected to the housing 1;

[0053] The auxiliary wheel 61 is rotatably connected to the U-shaped frame 64 by the connecting shaft 63 and the connecting block 62, which not only facilitates the auxiliary wheel 61 to roll, but also facilitates the auxiliary wheel 61 to be adjusted in a fan shape with the connecting shaft 63 as the center, so as to meet the guiding work of different surfaces;

[0054] Both ends of the other connecting shaft 63 are rotatably connected with inclined driving plates 65, and the adjusting member is used to drive the top ends of the two driving plates 65 up and down;

[0055] The adjusting member is used to drive the top ends of the two driving plates 65 up and down. By moving the top ends of the two driving plates 65 up and down, the two inclined driving plates 65 can move in a fan shape, thereby forming the auxiliary wheel 61 for angle adjustment, and the angle range is 0-90 degrees.

[0056] See attached Figure 5 The adjusting member includes a threaded rod 66 rotatably connected to the housing 1 through a bracket, a sliding frame 67 is threadedly connected to the outer surface of the threaded rod 66, and the sliding frame 67 is slidably connected to the side of the housing 1, and the top ends of the two driving plates 65 are rotatably connected to the sliding frame 67 through a rotating shaft;

[0057] By manually rotating the threaded rod 66, the sliding frame 67 can be driven to move up and down. The up and down movement of the sliding frame 67 can drive the two inclined driving plates 65 to move in a fan shape, thereby forming an auxiliary wheel 61 for angle adjustment. The angle range is 0-90 degrees, which not only satisfies the positioning and rolling of the horizontal or vertical plane, but also satisfies the positioning and rolling of other angles, further improving the guiding performance of the equipment and increasing the grinding effect of the uneven edge area of ​​the road surface.

[0058] The threaded rod 66 can be replaced by an electric cylinder to achieve electric adjustment.

[0059] See attached Figure 8 and Fig. 9 The grinding mechanism 4 includes a support plate 44 fixed on the housing 1, the bottom of the support plate 44 is fixedly connected to the grinding cover 41 through two sets of telescopic frames 45, the interior of the support plate 44 is rotatably connected with a rotating shaft 46, the bottom end of the rotating shaft 46 extends to the interior of the grinding cover 41, and the bottom end of the rotating shaft 46 is connected to the grinding disc 42;

[0060] The grinding cover 41 is connected to the support plate 44 by two sets of telescopic frames 45, so as to improve the stability of the grinding cover 41 and the grinding disc 42 during operation. The grinding disc 42 can be driven to rotate by the rotation of the rotating shaft 46, so as to perform grinding work on the uneven road surface area, and the grinding cover 41 is used to protect the grinding area.

[0061] The motor 43 is fixed to the top of the support plate 44, and the output shaft of the motor 43 and the top of the rotating shaft 46 are both fixedly connected with mutually meshing bevel gears 47;

[0062] The motor 43 is connected to an external power source and a control switch, and is used to drive one of the bevel gears 47 to rotate. By meshing the two bevel gears 47, the other bevel gear 47 can rotate synchronously, thereby driving the rotating shaft 46 to rotate. The rotation of the rotating shaft 46 can drive the grinding disc 42 to rotate, thereby performing a grinding operation on uneven road surfaces.

[0063] Embodiment 2: Based on embodiment 1, the difference is that;

[0064] See attached Figure 8 and Fig. 9 , a buffer member 48 for buffering the grinding disc 42 is provided inside the rotating shaft 46;

[0065] The buffer member 48 is provided to buffer the grinding disc 42, which not only improves the grinding ability of the grinding disc 42 but also reduces the probability of damage to the grinding disc 42, thereby increasing its service life.

[0066] The buffer member 48 includes a sleeve 481 fixed to the bottom end of the rotating shaft 46, and a telescopic shaft 482 is slidably connected inside the sleeve 481, and the bottom end of the telescopic shaft 482 extends to the inside of the grinding cover 41, and the bottom end of the telescopic shaft 482 is detachably connected to the grinding disc 42, and a spring 483 for compressing the telescopic shaft 482 is arranged inside the sleeve 481;

[0067] The rotating shaft 46 is connected to the grinding disc 42 by a sleeve 481 and a telescopic shaft 482, so that when the rotating shaft 46 rotates, the grinding disc 42 can be driven to rotate by the sleeve 481 and the telescopic shaft 482 to form a grinding operation;

[0068] The telescopic shaft 482 is installed inside the sleeve 481 in an up-and-down sliding manner, so that when the uneven area has a large or high protrusion and is difficult to grind, the telescopic shaft 482 can drive the grinding disc 42 to retract upward to form a protective work for the grinding disc 42. A spring 483 for squeezing the telescopic shaft 482 is arranged inside the sleeve 481. The elastic force of the spring 483 can squeeze the telescopic shaft 482 downward, so that the grinding disc 42 that has retracted upward moves downward, forming a step-by-step grinding work, which not only improves the grinding effect, but also reduces the damage to the grinding disc 42.

[0069] The inside of the sleeve 481 is slidably connected with an adjustment plate 484, and the spring 483 is fixed between the adjustment plate 484 and the telescopic shaft 482. The inside of the rotating shaft 46 is rotatably connected with a transmission shaft 485, and the bottom end of the transmission shaft 485 is connected with the internal thread of the adjustment plate 484, and the outer surface of the bottom end of the transmission shaft 485 is provided with an external thread;

[0070] By driving the transmission shaft 485 in rotation, the adjustment plate 484 can be driven to move up and down. By the up and down movement of the adjustment plate 484, the initial position of the spring 483 can be adjusted, and the squeezing force of the spring 483 on the telescopic shaft 482 can be indirectly controlled to meet the different contact forces between the grinding disc 42 and the protrusions of the uneven area of ​​the road edge;

[0071] This not only avoids the problem of the grinding disc 42 being easily damaged during long-term operation when the contact force of the grinding disc 42 is large, but also avoids the problem of the grinding disc 42 being unable to effectively and quickly process the protrusions in the uneven area when the contact force of the grinding disc 42 is small, thereby improving the grinding effect.

[0072] Embodiment 3: Based on embodiment 1, the difference is that;

[0073] See attached Figure 4 , Figure 6 and Figure 7 The processing mechanism 5 includes a negative pressure cylinder 51 fixed inside the shell 1, and the negative pressure cylinder 51 has a piston plate 52 slidably connected to the inside of the negative pressure cylinder 51 in an up-and-down sliding manner. The top of the piston plate 52 is fixedly connected to a driving shaft 53, and the top of the driving shaft 53 extends to the top of the shell 1. An electric telescopic rod 54 is fixedly connected to the shell 1, and the telescopic end of the electric telescopic rod 54 is fixedly connected to the top of the driving shaft 53 through a fixing frame. The top of the shell 1 is fixedly connected to an air guide pipe;

[0074] The electric telescopic rod 54 is connected to an external power source and a control switch, and is used to drive the driving shaft 53 to move up and down through the fixing frame, thereby driving the piston plate 52 to reciprocate up and down;

[0075] Through the up and down movement of the piston plate 52, not only can the dust gas generated during the grinding process be extracted through the absorption part, but the extracted dust gas can also be purified through the purification part at the same time, which has a good linkage function, not only improves the energy saving and environmental protection of the equipment, but also improves the dust treatment effect in the gas;

[0076] The invention solves the problem that the filtering effect is poor and clogging is easy to occur when the single filter net method or water spray method is generally used in the prior art, and the problem that the water source demand is large when the water spray method is used.

[0077] See attached Figure 6 and Figure 7 The absorber includes an exhaust pipe 55 and an exhaust pipe 56 fixed to the bottom of the negative pressure cylinder 51. The bottom end of the exhaust pipe 55 extends to the bottom of the housing 1. One end of the exhaust pipe 56 is fixedly connected to the inside of the grinding cover 41. One end of the exhaust pipe 56 is made of a bellows material. The exhaust pipe 55 and the exhaust pipe 56 are both equipped with a first one-way valve.

[0078] The upward movement of the piston plate 52 can make the space below the piston plate 52 in a negative pressure state, and the dust gas inside the grinding cover 41 can be extracted through the exhaust pipe 56. With the downward movement of the piston plate 52, the extracted dust gas can be squeezed, so that the dust gas is discharged to the water source at the bottom of the shell 1 through the exhaust pipe 55, forming a preliminary purification work of the dust gas;

[0079] One end of the air extraction pipe 56 is made of a bellows material, so that when the air extraction pipe 56 is fixedly connected to the grinding cover 41 , the up and down buffering movement of the grinding cover 41 will not be affected.

[0080] See attached Figure 6 and Figure 7 The purification element includes a water suction pipe 57 and a drainage pipe 58 fixed to the top of the negative pressure cylinder 51, one end of the water suction pipe 57 and the drainage pipe 58 are extended to the inside of the shell 1, and a filter cartridge is installed at the bottom of the water suction pipe 57, and a second one-way valve is installed on the water suction pipe 57 and the drainage pipe 58. One end of the drainage pipe 58 is fixedly connected to a dispersion pipe 59, and the outer surface of the dispersion pipe 59 is provided with a plurality of atomization ports. A water source is stored inside the shell 1, and a sewage pipe is fixedly connected to the bottom of the shell 1;

[0081] The downward movement of the piston plate 52 can make the space above the piston plate 52 in a negative pressure state, and then the water source at the bottom of the housing 1 can be extracted through the water extraction pipe 57 and stored in the negative pressure cylinder 51;

[0082] In conjunction with the upward movement of the piston plate 52, the extracted water source can be introduced into the interior of the dispersion pipe 59 through the drainage pipe 58, and sprayed into the interior of the housing 1 through a plurality of atomization ports on the outer surface of the dispersion pipe 59. At this time, the gas in the rising process after the water treatment can be sprayed and atomized, and the dust in the gas can be further removed, thereby further improving the dust gas treatment effect and the quality of the working environment;

[0083] The sewage pipe is provided to discharge the sewage inside the shell 1, and the air duct is provided to not only facilitate the discharge of the gas after dust treatment, but also facilitate the injection of water source in the early stage, so as to facilitate the subsequent treatment of dust in the gas through the water source.

[0084] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article, or device.
