[0012] Beneficial effects
[0013] This utility model provides a concrete pavement cutting device for municipal engineering. Compared with the prior art, it has the following advantages:
[0014] In this utility model, when the trolley body moves, it can drive the entire equipment to move synchronously. Through the setting of the transmission component, it can drive the cutting component to press down and cut the road surface. Through the setting of the cutting component, it always keeps in contact with the road surface and blocks the cutting surface of the cutting component, so that the sand and stones generated by the road surface cutting will not fly around.
[0015] The roller design prevents the dust cover from rubbing against the road surface. The sliding mechanism of the limit slider and limit rod, along with the elasticity of the spring, ensures that the dust cover remains in contact with the road surface under the counterforce of the spring, thus providing good protection for the workers.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1:
[0025] Please see Figure 1-4A concrete pavement cutting device for municipal engineering includes a trolley body 1, a transmission assembly 5, a cutting assembly 6, and a protective assembly 7. The front side of the trolley body 1 is longitudinally provided with first limiting grooves 2 near both sides. Limiting rods 3 are fixedly welded between the upper and lower inner walls of the two first limiting grooves 2. Limiting frames 4 are fixedly welded to the front side of the trolley body 1 near both sides. The transmission assembly 5 is fixedly installed on the inner bottom surface of the trolley body 1. The cutting assembly 6 is fixedly welded to the transmission assembly 5 and is slidably installed with the limiting frame 4. The protective assembly 7 is slidably sleeved between the outer surfaces of the two limiting rods 3.
[0026] In this embodiment, the trolley body 1 can move the entire equipment synchronously when it moves. The transmission component 5 can drive the cutting component 6 to press down and cut the road surface. The cutting component 6 is always in close contact with the road surface and blocks the cutting surface of the cutting component 6, so that the sand and stones generated by the road surface cutting will not fly around, thus providing a good protective effect for the workers.
[0027] The transmission assembly 5 includes a hydraulic push rod 51, which is fixedly installed on the inner bottom surface of the trolley body 1. The output end of the hydraulic push rod 51 extends out of the top of the trolley body 1. A lifting platform 52 is fixedly welded to the output end of the hydraulic push rod 51. A water tank 53 is fixedly installed on the top of the lifting platform 52. Limiting slide rods 54 are telescopically slidably installed on both sides of the top of the trolley body 1 near the hydraulic push rod 51. The top ends of the two limiting slide rods 54 are fixedly welded to the bottom of the lifting platform 52. Transmission rods 55 are fixedly welded to the two corners near the front side of the bottom of the lifting platform 52.
[0028] The cutting assembly 6 includes a limiting plate 61. The top of the limiting plate 61 is fixedly welded to the bottom of two transmission rods 55. The limiting plate 61 is slidably disposed between the interiors of the two limiting frames 4. An outer protective frame 62 is fixedly welded to the front side of the limiting plate 61. A motor 63 is fixedly installed on one side of the outer protective frame 62. A rotating rod 64 is rotatably connected between the inner surfaces of the two sides of the outer protective frame 62. One end of the rotating rod 64 is fixedly welded to the output shaft of the motor 63. A cutting blade 65 is fixedly sleeved on the outer surface of the rotating rod 64.
[0029] In this embodiment, the limiting slide bar 54 allows the hydraulic push rod 51 to drive the lifting platform 52 to move up and down smoothly when it outputs. This, in turn, drives the limiting plate 61 to slide up and down via the transmission rod 55. The limiting frame 4 makes the sliding of the limiting plate 61 more stable. When the motor 63 starts, it drives the rotating rod 64 to rotate, thereby driving the cutting blade 65 to cut the road surface. The water tank 53 on the top of the lifting platform 52 can continuously spray water onto the cutting blade 65, preventing the generation of a large amount of dust.
[0030] Example 2:
[0031] Please see Figure 1-6 This embodiment provides a technical solution based on embodiment one: the protective component 7 includes a limiting slider 71, and there are two limiting sliders 71. The limiting sliders 71 are slidably sleeved on the outer surface of the limiting rod 3. The top of the two limiting sliders 71 is fixedly welded to the outer surface of the limiting rod 3. The top of the spring 72 is fixedly welded to the inner top surface of the first limiting groove 2. An inner protective frame 73 is fixedly welded between the opposite sides of the two limiting sliders 71. A clearance groove 74 is opened on the top of the inner protective frame 73 near the rear side. The clearance groove 74 is slidably fitted with the limiting plate 61. A blade slide groove 75 is longitudinally opened on the top of the inner protective frame 73 near the front side. A second limiting groove 76 is opened on the top of the inner protective frame 73 near the center of the blade slide groove 75. The second limiting groove 76 is slidably fitted with the rotating rod 64. A dust cover 77 is fixedly welded to the bottom of the inner protective frame 73. Rollers 78 are rotatably arranged on the bottom of the dust cover 77 near the front and rear sides.
[0032] In this embodiment, when the trolley body 1 moves continuously, the setting of the roller 78 prevents the dust cover 77 from rubbing against the road surface. The sliding setting of the limiting slider 71 and the limiting rod 3, as well as the setting of the spring 72, ensure that the dust cover 77 is always in contact with the road surface, achieving a good protective effect. The opening of the clearance groove 74 provides clearance for the limiting plate 61, preventing the limiting plate 61 from colliding with the inner protective frame 73. When the limiting plate 61 slides down, it will drive the rotating rod 64 to slide into the inside of the second limiting groove 76, and cause the outer protective frame 62 to be fitted onto the outer surface of the inner protective frame 73. At the same time, it will drive the cutting blade 65 to slide into the inside of the blade groove 75. Through the continuous downward adjustment of the limiting plate 61, it will drive the cutting blade 65 to cut the bottom surface.
[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0034] During operation, the trolley body 1 moves to move the entire equipment to the designated cutting position. The motor 63 starts and rotates the rotating rod 64, which in turn rotates the cutting blade 65. The hydraulic push rod 51 is controlled to retract inward, which causes the lifting platform 52 to descend smoothly. At the same time, the transmission rod 55 drives the limiting plate 61 to descend synchronously. When the limiting plate 61 slides down, it causes the rotating rod 64 to slide into the second limiting groove 76, and the outer protective frame 62 is fitted onto the outer surface of the inner protective frame 73. At the same time, the cutting blade 65 slides into the blade groove 75. Through the continuous downward adjustment of the limiting plate 61, the cutting blade 65 cuts the bottom surface. The water tank 53 set on the top of the lifting platform 52 can continuously spray water onto the cutting blade 65 to avoid the generation of a large amount of dust.
[0035] As the trolley body 1 moves continuously, the roller 78 prevents the dust cover 77 from rubbing against the road surface. The sliding setting of the limit slider 71 and the limit rod 3, as well as the elastic setting of the spring 72, ensure that the dust cover 77 always fits in contact with the road surface, preventing sand and stones generated by road cutting from flying everywhere, thus providing good protection for the workers.
