Description

Technical Field

[0001] This application relates to the field of municipal engineering equipment technology, and in particular to a municipal road and bridge surface spraying and maintenance equipment. Background Technology

[0002] With the acceleration of urbanization, the maintenance quality of roads and bridges, as crucial infrastructure, directly impacts traffic safety and socio-economic development. Traditional road and bridge maintenance relies heavily on manual labor or simple mechanical equipment, resulting in low efficiency, high costs, and an inability to meet the demands of modern urban management. In recent years, advancements in technology have led to the development of increasingly automated and intelligent maintenance equipment, significantly improving work efficiency and reducing labor intensity.

[0003] Under relevant technologies, common road surface water treatment maintenance equipment mainly includes manual cart-type, tractor-mounted type, and special vehicle-mounted type. Among them, manual cart-type equipment has good flexibility but requires a lot of manpower and is suitable for small-scale precision operations; tractor-mounted type can cover a larger area, but it is difficult to implement in busy urban areas.

[0004] Regarding the aforementioned technologies, existing spraying equipment is mostly designed in a fixed mode, which cannot adjust the spraying range according to different road widths. If the road is wide, the fixed nozzles need to spray repeatedly to cover the entire road surface, resulting in low maintenance efficiency. Therefore, there is an urgent need for a device that can expand the spraying range of the nozzles. Utility Model Content

[0005] In order to expand the spraying range of the nozzles, this application provides a municipal road and bridge surface spraying and maintenance device.

[0006] This application provides a municipal road and bridge surface spraying and maintenance equipment, which adopts the following technical solution:

[0007] A municipal road and bridge deck spraying and maintenance equipment includes a frame, a cylinder, and spraying components;

[0008] The cylinder is fixedly connected to the vehicle frame, and a feed inlet is provided on one side of the cylinder;

[0009] The spraying assembly includes a connecting seat, a water pipe, and a nozzle. The connecting seat is disposed on the cylinder and the nozzle is connected to the connecting seat. The connecting seat is slidably connected to the cylinder along a second direction, which is perpendicular to the first direction. One end of the water pipe is connected to the cylinder and the other end is connected to the nozzle.

[0010] By adopting the above technical solution, multiple nozzles are set up. The nozzles are connected to the cylinder through water pipes. The maintenance liquid in the cylinder enters the nozzles through the water pipes and is sprayed out by the nozzles. If the road surface is wide, the fixed nozzles need to spray repeatedly to cover the entire road surface, resulting in low maintenance efficiency. Therefore, by setting a connecting seat to slide along the second direction, the nozzles can be moved along the second direction, so that the nozzles can achieve spraying over a larger area and improve the efficiency of road surface spraying and maintenance.

[0011] Optionally, it also includes a stirring assembly, which includes a stirring shaft that is parallel to the first direction and parallel to the depth direction of the cylinder. One end of the stirring shaft is located inside the cylinder, and the other end passes through the top wall of the cylinder and is located outside the cylinder. The stirring shaft is rotatably connected to the cylinder and is parallel to the first direction along the rotation axis of the cylinder.

[0012] By adopting the above technical solution, in order to facilitate the stirring of the curing solution and prevent some substances in the curing solution from settling, which would greatly reduce the curing effect of the curing solution, a stirring shaft is set up. The stirring shaft rotates in the first direction inside the cylinder to stir the curing solution inside the cylinder and prevent some substances in the curing solution from settling.

[0013] Optionally, the stirring assembly further includes a plurality of stirring rods, which are spaced apart circumferentially along the stirring shaft, and one end of each stirring rod is fixedly connected to the stirring shaft.

[0014] By adopting the above technical solution and setting multiple stirring rods on the stirring shaft, the stirring efficiency of the curing solution can be improved.

[0015] Optionally, it may also include a second drive assembly, which includes an incomplete gear and rack;

[0016] The incomplete gear is coaxially sleeved on the stirring shaft, and the incomplete gear is located on the outside of the cylinder;

[0017] The rack is parallel to the second direction, and a first groove is formed on the cylinder along the second direction. One side of the rack is located in the first groove and slides along the groove wall. A plurality of first tooth grooves are formed on one side of the rack along its own length direction. The incomplete gear meshes with the first tooth grooves. The end of the connecting seat away from the nozzle is fixedly connected to the rack.

[0018] By adopting the above technical solution, in order to drive the connecting seat to slide in the second direction, a second driving component is set up. When the stirring shaft rotates in the first direction, it drives the incomplete gear to rotate, which drives the rack to slide on the slide rail in the second direction, and further drives the nozzle to slide in the second direction through the connecting seat.

[0019] Optionally, the second drive assembly further includes a mounting base and an elastic element. Each end of the slide rail is fixedly connected to a mounting base. The extension and retraction direction of the elastic element is parallel to the second direction. Each end of the rack is provided with an elastic element. One end of the elastic element is fixedly connected to the mounting base, and the other end is fixedly connected to the rack.

[0020] By adopting the above technical solution, in order to enable the rack to be reset, the second drive assembly also includes an elastic element. When the teeth on the incomplete gear rotate to the side away from the rack, under the action of the elastic element, the rack slides in the opposite direction in the second direction, which can reset the rack and expand the spraying range of the nozzle.

[0021] Optionally, the connecting seat includes a horizontal section and a vertical section fixedly connected, a first mounting rod is fixedly connected to the rack, the first mounting rod is parallel to a first direction, one end of the horizontal section is rotatably connected to the first mounting rod, the horizontal section is parallel to a second direction along the rotation axis of the first mounting rod, the end of the vertical section away from the horizontal section is connected to the nozzle, the water pipe is connected to the vertical section, and there is a space between the vertical section and the outer wall of the cylinder.

[0022] By adopting the above technical solution, in order to further expand the spraying range of the nozzle, the connecting seat includes a horizontal section and a vertical section that are fixedly connected. The horizontal section is rotatably connected to the rack in the second direction, so that the horizontal section can rotate in the direction close to or away from the cylinder, thereby further expanding the spraying range and improving the maintenance efficiency of the road surface.

[0023] Optionally, it may also include a third drive assembly, which includes a screw, a first gear, and a sliding seat;

[0024] The screw is parallel to the first direction, the screw is located between the cylinder and the horizontal section, and one end of the screw is rotatably connected to the top wall of the cylinder;

[0025] The first gear is coaxially sleeved on the screw, and the rack has a plurality of second tooth grooves along the second direction on the side away from the incomplete gear. The first gear meshes with the second tooth grooves of the rack.

[0026] The sliding seat is sleeved on the screw and slides along the length of the screw. A ball is fixedly connected to the side of the sliding seat near the horizontal section. When the sliding seat slides along the length of the screw, the ball contacts the horizontal section.

[0027] By adopting the above technical solution, in order to drive the horizontal section to rotate in the second direction, a third driving component is set up. When the rack slides in the second direction, it drives the first gear to rotate, which in turn drives the screw to rotate, causing the sliding seat to slide in the first direction. The ball contacts the horizontal section, so that the ball lifts the horizontal section, realizing the rotation of the horizontal and vertical sections in the second direction, thereby expanding the spraying range of the nozzle.

[0028] Optionally, a fixing plate is fixedly connected to the horizontal segment, the fixing plate is parallel to the second direction, and the fixing plate is fixedly connected to the horizontal segment. When the first gear rotates, the ball contacts the fixing plate.

[0029] By adopting the above technical solution, when the rack slides along the second direction, the horizontal section will also slide along the second direction. In order to allow the ball to have more contact time with the horizontal section and to lift the horizontal section to rotate, a fixed plate is set. The fixed plate is parallel to the second direction so that when the rack slides, the ball can have a longer contact time with the fixed plate in the second direction, thereby lifting the horizontal and vertical sections.

[0030] Optionally, it also includes a first drive assembly, which includes a first shaft and at least two wheels. The first shaft is parallel to a second direction and is rotatably connected to the cylinder. The wheels are coaxially fixedly connected to the first shaft.

[0031] By adopting the above technical solution, in order to enable the spraying assembly to move along the road and bridge surface, a first drive assembly is set up, with the wheels coaxially fixedly sleeved on the first rotating shaft, and the cylinder is moved by the wheels.

[0032] Optionally, the first drive assembly further includes a first bevel gear, a second bevel gear, and a second rotating shaft. The first bevel gear is fixedly sleeved on the first rotating shaft, and the second rotating shaft is parallel to the first direction. One end of the second rotating shaft is located outside the cylinder, and the other end passes through the bottom wall of the cylinder and is fixedly connected to the stirring shaft. The second bevel gear is fixedly sleeved on the second rotating shaft, and the first bevel gear and the second bevel gear mesh.

[0033] By adopting the above technical solution, in order to drive the stirring shaft to rotate, the first rotating shaft drives the first bevel gear, the second bevel gear and the second rotating shaft to rotate, which in turn drives the stirring shaft and the stirring rod to rotate. Therefore, no additional drive structure is needed, and the stirring of the maintenance liquid can be achieved simply by moving the frame.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. This application sets the connecting seat to slide along the second direction, thereby driving the nozzle to slide along the second direction, so that the nozzle can achieve spraying over a larger area and improve the efficiency of road spraying and maintenance;

[0046] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0047] This application discloses a municipal road and bridge surface spraying and maintenance device. (Refer to...) Figure 1 The municipal road and bridge surface spraying and maintenance equipment includes a frame 1, a cylinder 2, and a spraying assembly 3. The cylinder 2 is fixedly connected to the frame 1, and a feed inlet 21 is provided on one side of the cylinder 2. The spraying assembly 3 includes a connecting seat 31, a water pipe 32, and a nozzle 33. The connecting seat 31 is located on the cylinder 2, and the nozzle 33 is connected to the connecting seat 31. The connecting seat 31 is slidably connected to the cylinder 2 along a second direction, which is perpendicular to the first direction. One end of the water pipe 32 is connected to the cylinder 2, and the other end is connected to the nozzle 33. The cylinder 2 contains the maintenance liquid used for spraying and maintaining the road and bridge surface. The maintenance liquid enters the water pipe 32 from the cylinder 2, and further enters the nozzle 33, and is sprayed out by the nozzle 33. The connecting seat 31 slides along the second direction, thereby driving multiple nozzles 33 to slide along the second direction, thereby expanding the spraying range of the nozzles 33 on the bridge surface.

[0048] Reference Figure 1 In order to facilitate the extraction of the curing solution from the cylinder 2 to the water pipe 32, the water pipe 32 is connected to the cylinder 2 through a connecting pipe 321. A water pump 322 is connected to the connecting pipe 321. When the water pump 322 is turned on, the curing solution is extracted from the cylinder 2 to the water pipe 32 and further enters the nozzle 33. In this embodiment, the water pipe 32 is a flexible hose.

[0049] Reference Figure 2 To improve spraying efficiency, multiple nozzles 33 are provided. Multiple nozzles 33 are connected by a fixed base 331. The fixed base 331 is hollow and the nozzles 33 are connected to the fixed base 331. The end of the water pipe 32 away from the cylinder 2 is connected to the fixed base 331.

[0050] Reference Figure 1 To facilitate the movement of the frame 1 by personnel, a handle 11 is fixedly connected to the frame 1.

[0051] Reference Figure 3 To facilitate stirring of the curing solution and prevent sedimentation of some substances in the curing solution, the municipal road and bridge surface spraying and curing equipment also includes a stirring component 4. The stirring component 4 includes a stirring shaft 41, which is parallel to the first direction and parallel to the depth direction of the cylinder 2. One end of the stirring shaft 41 is located inside the cylinder 2, and the other end passes through the top wall of the cylinder 2 and is located outside the cylinder 2. The stirring shaft 41 is rotatably connected to the cylinder 2. The stirring shaft 41 is parallel to the first direction along the rotation axis of the cylinder 2. The rotation of the stirring shaft 41 stirs the curing solution to improve its quality.

[0052] Reference Figure 3 To further improve the mixing efficiency, the mixing assembly 4 also includes multiple mixing rods 42, which are distributed circumferentially along the mixing shaft 41, with one end of each mixing rod 42 fixedly connected to the mixing shaft 41.

[0053] Reference Figure 3 In order to enable the spraying assembly 3 to move along the road and bridge surface, the municipal road and bridge surface spraying and maintenance equipment also includes a first drive assembly 5. The first drive assembly 5 includes a first rotating shaft 51 and at least two wheels 52. The first rotating shaft 51 is parallel to the second direction and is rotatably connected to the frame 1. The rotation axis of the first rotating shaft 51 and the frame 1 is parallel to the second direction. In this embodiment, there are two wheels 52, and the two wheels 52 are coaxially fixedly sleeved at both ends of the first rotating shaft 51. The cylinder 2 is moved by the two wheels 52. In this embodiment, there are multiple first rotating shafts 51 along a third direction, which is perpendicular to both the first direction and the second direction. Each first rotating shaft 51 has a wheel 52 sleeved at both ends.

[0054] Reference Figure 3 In order to ensure that the first rotating shaft 51 can rotate smoothly along the frame 1, the first rotating shaft 51 is rotatably connected to the frame 1 through the bearing 511, and the outer peripheral wall of the first rotating shaft 51 is interference-fitted with the inner peripheral wall of the bearing 511, and the outer peripheral wall of the bearing 511 is also interference-fitted with the frame 1.

[0055] Reference Figure 4To drive the stirring shaft 41 to rotate, the first drive assembly 5 also includes a first bevel gear 53, a second bevel gear 54, and a second rotating shaft 55. The first bevel gear 53 is fixedly sleeved on a first rotating shaft 51. The second rotating shaft 55 is parallel to the first direction. One end of the second rotating shaft 55 is located outside the cylinder 2, and the other end passes through the bottom wall of the cylinder 2 and is fixedly connected to the stirring shaft 41. The second bevel gear 54 is fixedly sleeved on the second rotating shaft 55. The first bevel gear 53 and the second bevel gear 54 mesh. When a person pushes the handle 11, the wheel 52 rotates, which drives the first bevel gear 53, the second bevel gear 54, and the second rotating shaft 55 to rotate through the first rotating shaft 51, further driving the stirring shaft 41 and the stirring rod 42 to rotate. Thus, no additional drive structure is needed; the stirring of the maintenance liquid can be achieved simply by moving the frame 1.

[0056] Reference Figure 5 To drive the connecting seat 31 to slide along the second direction, the municipal road and bridge surface spraying and maintenance equipment also includes a second drive assembly 6. The second drive assembly 6 includes an incomplete gear 61, a slide rail 62, and a rack 63. The incomplete gear 61 is coaxially sleeved on the stirring shaft 41 and is located on the outside of the cylinder 2. The slide rail 62 is parallel to the second direction and is fixedly connected to the top wall of the cylinder 2. The rack 63 is parallel to the second direction and has a first groove 631 extending through it along the second direction. The slide rail 62 passes through the first groove 631, and the rack 63 slides along the slide rail 631. The rack 63 slides along its length direction. One side of the rack 63 has multiple first tooth grooves 632 along its own length direction. The incomplete gear 61 meshes with the first tooth grooves 632. The end of the connecting seat 31 away from the nozzle 33 is connected to the rack 63. The incomplete gear 61 is a gear with partial teeth. The incomplete gear 61 meshes with the first tooth grooves 632 of the rack 63. When the stirring shaft 41 rotates in the first direction, it drives the incomplete gear 61 to rotate, which drives the rack 63 to slide on the slide rail 62 in the second direction. Furthermore, the connecting seat 31 drives the nozzle 33 to slide in the second direction.

[0057] Reference Figure 5 To enable the rack 63 to reset, the second drive assembly 6 also includes a mounting base 64 and an elastic element 65. A mounting base 64 is fixedly connected to each end of the slide rail 62. The extension and retraction direction of the elastic element 65 is parallel to the second direction. An elastic element 65 is provided at each end of the rack 63. One end of the elastic element 65 is fixedly connected to the mounting base 64, and the other end is fixedly connected to the rack 63. In this embodiment, one elastic element 65 is a tension spring, and the other elastic element 65 is a compression spring. When the incomplete gear 61 rotates, causing the rack 63 to slide along the second direction, one elastic element 65 changes from its normal state to a tensioned state, and the other elastic element 65 changes from its normal state to a compressed state. When the teeth on the incomplete gear 61 rotate to a side away from the rack 63, under the action of the elastic element 65, the rack 63 slides in the opposite direction along the second direction, which can expand the spray range of the nozzle 33.

[0058] Reference Figure 5 To further expand the spraying range of the nozzle 33, the connecting seat 31 includes a horizontal section 311 and a vertical section 312 that are fixedly connected. A first mounting rod 633 is fixedly connected to the rack 63. The first mounting rod 633 is parallel to a first direction. One end of the horizontal section 311 is rotatably connected to the first mounting rod 633. The horizontal section 311 is parallel to a second direction along the rotation axis of the first mounting rod 633. The nozzle 33 is connected to the end of the vertical section 312 away from the horizontal section 311. A water pipe 32 is connected to the vertical section 312. There is a space 3121 between the vertical section 312 and the outer wall of the cylinder 2, so that the vertical section 312 can rotate within the space 3121. The horizontal section 311 rotates along the first mounting rod 633 in the second direction, driving the nozzle 33 to rotate in the second direction, so that the nozzle 33 has a larger spraying range and improves the spraying and maintenance efficiency.

[0059] Reference Figure 6 To drive the rotation of the horizontal section 311 along the mounting rod, the municipal road and bridge surface spraying and maintenance equipment also includes a third drive assembly 7. The third drive assembly 7 includes a screw 71, a first gear 72, a sliding seat 73, and a fixing plate 74. The screw 71 is parallel to the first direction and is located between the cylinder 2 and the horizontal section 311, with one end of the screw 71 rotatably connected to the top wall of the cylinder 2. The first gear 72 is coaxially sleeved on the screw 71. The rack 63 has multiple second tooth grooves 634 along the second direction on the side away from the incomplete gear 61. The first gear 72 meshes with the second tooth grooves 634 of the rack 63. The sliding seat 73 is sleeved on the screw 71. Furthermore, the ball 731 is fixedly connected to the side of the sliding seat 73 near the horizontal section 311, which slides along the length of the screw 71. When the sliding seat 73 slides along the length of the screw 71, the ball 731 contacts the horizontal section 311. When the rack 63 slides along the second direction, it drives the first gear 72 to rotate, which in turn drives the screw 71 to rotate, further driving the sliding seat 73 to slide along the length of the screw 71. When the sliding seat 73 slides toward the side of the horizontal section 311, the ball 731 contacts the horizontal section 311 and lifts the horizontal section 311, thereby realizing the rotation of the horizontal section 311 and the vertical section 312, further expanding the spraying range of the nozzle 33.

[0060] Reference Figure 7As the rack 63 slides along the second direction, the horizontal section 311 also slides along the second direction. In order to allow the ball 731 to have more contact time with the horizontal section 311 and to lift the horizontal section 311 to rotate, a fixed plate 74 is fixedly connected to the horizontal section 311. The fixed plate 74 is parallel to the second direction and is fixedly connected to the horizontal section 311. When the first gear 72 rotates, the ball 731 contacts the fixed plate 74. Since the fixed plate 74 is parallel to the second direction, when the rack 63 slides along the second direction, the screw 71 is driven to rotate by the first gear 72. The ball 731 on the sliding seat 73 can contact the fixed plate 74 for a period of time so that the ball 731 can lift the horizontal section 311 and the vertical section 312.

[0061] Reference Figure 7 In order to guide the sliding seat 73 to slide along the length of the screw 71, the municipal road and bridge surface spraying and maintenance equipment also includes a guide rod 8. The guide rod 8 is parallel to the first direction. One end of the guide rod 8 is fixedly connected to the top wall of the cylinder 2. A second mounting rod 732 is fixedly connected to one side of the sliding seat 73. The other end of the second mounting rod 732 is sleeved on the guide rod 8 and slides along the length of the guide rod 8.

[0062] The implementation principle of a municipal road and bridge surface spraying and maintenance equipment according to an embodiment of this application is as follows: During operation, the personnel push the handle 11 to move the frame 1, which in turn drives the first rotating shaft 51 to rotate. This rotation is further driven by the first bevel gear 53, the second bevel gear 54, and the second rotating shaft 55, which in turn drives the stirring shaft 41 and the stirring rod 42 to rotate. Thus, no additional drive structure is required, and the stirring of the maintenance liquid can be achieved simply by moving the frame 1.

[0063] The rotation of the mixing shaft 41 drives the incomplete gear 61 to rotate, which in turn drives the rack 63 to slide in the second direction. The rack 63 drives the connecting seat 31 and the nozzle 33 to slide in the second direction, thereby expanding the spraying and maintenance range of the nozzle 33 on the road surface.

[0064] When the rack 63 slides along the second direction, it drives the first gear 72 to rotate, drives the screw 71 to rotate, drives the sliding seat 73 to slide along the length of the screw 71, further drives the ball 731 to contact the fixed plate 74 and lifts the horizontal section 311 and the vertical section 312, so as to realize the change of different angles of the nozzle 33, thereby further expanding the spraying range of the nozzle 33.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
