Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering technology, and in particular relates to a road surface breaking device for municipal use. Background Technology

[0002] Municipal road engineering, as an important component of urban infrastructure, involves multiple aspects such as road construction, maintenance, and renovation. It mainly covers the technical foundations of design, construction, materials, and management. The pavement structure of municipal roads typically includes base course, subbase course, and surface course. Common pavement types include asphalt pavement and concrete pavement. Construction technology involves material selection, paving process, and compaction technology. Modern technologies also include warm-mix asphalt technology and cold recycling technology. With the increasing awareness of environmental protection, municipal road engineering has begun to widely adopt waste recycling technologies, such as cold recycling technology for waste asphalt pavement and crushing and recycling technology for concrete pavement, to improve material utilization and reduce resource consumption through technological means.

[0003] However, some devices used for road breaking have a relatively simple structure. These devices use a single large breaking counterweight to lift the counterweight and use gravity to release it to apply impact force to the road surface, causing it to break and crack. The frequent breaking operation of the single large counterweight may cause uneven movement of the overall equipment and the excessive force applied to the equipment when the counterweight is raised and lowered, which causes vibration and reduces the service life of the device to a certain extent. Utility Model Content

[0004] The purpose of this utility model is to provide a road surface breaking device for municipal use. By setting up a breaking mechanism, it realizes the use of a motor to drive the rotating shaft to rotate, which drives the staggered and oppositely oriented half gears, so that several breaking hammers are continuously raised and lowered in a staggered manner under the pull of the suspension rope to smash the road surface, thereby breaking the road surface. This solves the problems that may exist in the breaking operation of a single large hammer, such as uneven movement of the whole equipment and vibration caused by the extra force applied to the equipment when the hammer is raised and lowered.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a road surface breaking device for municipal use, including a shell, on which a breaking mechanism and an auxiliary mechanism are provided;

[0007] The crushing mechanism includes a tilting assembly, a pulley assembly, and a crushing assembly. The tilting assembly includes a rotating shaft rotatably connected to the inner wall of the outer shell. Several half-gears are fixedly connected to the outer wall of the rotating shaft. A motor is fixedly connected to the right side of the outer shell. The output end of the motor is fixedly connected to the right end of the rotating shaft. A first fixing rod is fixedly connected to the inner wall of the outer shell. Several gears are rotatably connected to the outer wall of the first fixing rod. Several winding drums are fixedly connected to the outer wall of the first fixing rod. The several half-gears mesh with the gears.

[0008] Furthermore, the pulley assembly includes suspension ropes that are all fixedly connected to the inner walls of several winding drums, a second fixing rod is fixedly connected to the inner wall of the outer casing, and several pulleys are rotatably connected to the outer wall of the second fixing rod.

[0009] Furthermore, the inner wall of the outer casing is provided with several connecting holes, the left side of several winding drums is fixedly connected to the right side of the gear, and the outer wall of several lifting ropes is slidably connected to the inner wall of the pulley.

[0010] Furthermore, the crushing assembly includes several grooves formed on the front of the housing, with a breaker hammer slidably connected to the inner wall of each groove, the ends of each of the lifting ropes extending to the inner wall of the groove and fixedly connected to the top surface of the breaker hammer, and a fixing plate fixedly connected to the inner wall of the housing.

[0011] Furthermore, the auxiliary mechanism includes a leveling component and an auxiliary component. The leveling component includes a receiving frame fixedly connected to the bottom surface of the housing. A roller is rotatably connected to the inner wall of the receiving frame, and several protrusions are fixedly connected to the outer wall of the roller. A brush guard is fixedly connected to the bottom surface of the housing.

[0012] Furthermore, the auxiliary component includes spring grooves that are all formed on the inner walls of several sliding grooves, the inner walls of several spring grooves are fixedly connected to limit rods, and the outer walls of several limit rods are slidably connected to sliders.

[0013] Furthermore, the front sides of several of the sliders are fixedly connected to the back side of the breaker, the top surfaces of several of the sliders are fixedly connected to springs, and the top ends of several of the springs are fixedly connected to the inner wall of the spring groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a crushing mechanism, the rotating shaft driven by the motor drives the staggered and oppositely oriented half gears, so that several breaker hammers are continuously raised and lowered in a staggered manner under the pull of the suspension rope to smash the road surface, thus crushing the road surface. This not only ensures that the impact points are evenly distributed when the device is in operation, but the staggered operation can also disperse the direct impact force of the breaker hammers on the device, thereby reducing wear and tear on the equipment and extending its service life to a certain extent.

[0016] 2. By setting up an auxiliary mechanism, the elastic force of the spring is used to drive the breaker hammer upward in conjunction with the crushing mechanism. By compressing the spring to store some mechanical energy, after the hoisting rope is released, the spring returns to its original state and releases the force through the slider, which is applied to the breaker hammer. Combined with gravity impact on the road surface, this breaks the surface. Compared with using only gravity impact, the combination of elastic force and gravity increases the kinetic energy to a certain extent, further enhancing the impact force of the device on the road surface. This makes it easier to complete the road surface breaking operation and further improves the practicality of the device.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is a road surface crushing device for municipal use, including a housing 1, on which a crushing mechanism 2 and an auxiliary mechanism 3 are provided;

[0028] The crushing mechanism 2 includes a tilting assembly, a pulley assembly, and a crushing assembly. The tilting assembly includes a rotating shaft 21 rotatably connected to the inner wall of the outer casing 1. Several half gears 22 are fixedly connected to the outer wall of the rotating shaft 21. A motor 23 is fixedly connected to the right side of the outer casing 1. The output end of the motor 23 is fixedly connected to the right end of the rotating shaft 21. A first fixing rod 24 is fixedly connected to the inner wall of the outer casing 1. Several gears 25 are rotatably connected to the outer wall of the first fixing rod 24. Several winding drums 26 are fixedly connected to the outer wall of the first fixing rod 24. The several half gears 22 mesh with the gears 25.

[0029] Among them, such as Figure 3 , Figure 4 and Figure 5 As shown, the pulley assembly includes suspension ropes 27 fixedly connected to the inner walls of several winding drums 26. A second fixing rod 28 is fixedly connected to the inner wall of the outer casing 1. Several pulleys 29 are rotatably connected to the outer wall of the second fixing rod 28. Several connecting holes 210 are provided on the inner wall of the outer casing 1. The left side of several winding drums 26 is fixedly connected to the right side of gear 25. The outer walls of several suspension ropes 27 are slidably connected to the inner walls of pulleys 29. The crushing assembly includes several grooves 211 opened on the front of the outer casing 1. A breaker hammer 212 is slidably connected to the inner wall of several grooves 211. The ends of several suspension ropes 27 extend to the inner wall of the grooves 211 and are fixedly connected to the top surface of the breaker hammer 212. A fixing plate 213 is fixedly connected to the inner wall of the outer casing 1.

[0030] By setting up the crushing mechanism 2, the rotating shaft 21 is driven by the motor 23 to rotate, which drives the staggered and oppositely oriented half gears 22. This causes several breaker hammers 212 to continuously rise and fall alternately under the pull of the suspension rope 27, smashing the road surface to crush it. This not only ensures that the impact points are evenly distributed during the operation of the device, but also disperses the direct impact force of the rising and falling of the breaker hammers 212 on the device, reducing wear and tear on the equipment and extending its service life to a certain extent.

[0031] Among them, such as Figure 2 , Figure 3 and Figure 5As shown, the auxiliary mechanism 3 includes a leveling component and an auxiliary component. The leveling component includes a receiving frame 31 fixedly connected to the bottom surface of the outer shell 1. A roller 32 is rotatably connected to the inner wall of the receiving frame 31. Several protrusions 33 are fixedly connected to the outer wall of the roller 32. A brush guard 34 is fixedly connected to the bottom surface of the outer shell 1. The auxiliary component includes spring grooves 35 all opened on the inner wall of several sliding grooves 211. Limiting rods 36 are fixedly connected to the inner wall of several spring grooves 35. Sliding sliders 37 are slidably connected to the outer wall of several limiting rods 36. The front of several sliders 37 is fixedly connected to the back of the breaker hammer 212. Springs 38 are fixedly connected to the top surface of several sliders 37. The top of several springs 38 is fixedly connected to the inner wall of the spring grooves 35.

[0032] By setting up auxiliary mechanism 3, the elastic force of spring 38 is used to drive the breaker hammer 212 to rise in conjunction with the crushing mechanism 2. By compressing spring 38, some mechanical energy is stored. After the hoisting rope 27 is released, the spring 38 returns to its original state and releases the force through slider 37, which is applied to the breaker hammer 212. Combined with gravity impact on the road surface, the breaker hammer crushes the road surface. Compared with gravity impact alone, the combination of elastic force and gravity increases the kinetic energy to a certain extent, which further enhances the impact force of the device on the road surface, making it easier to complete the road surface crushing operation and further improving the practicality of the device.

[0033] A specific application of this embodiment is as follows: By setting up the crushing mechanism 2, the device is first installed on the transport equipment via the fixing plate 213. After the device is moved to the road that needs to be modified, the roller 32 contacts the road. At this time, the drive motor 23 drives the rotating shaft 21 to rotate, causing several half gears 22 on the rotating shaft 21 to rotate around the rotating shaft 21. Since several half gears 22 are all meshed with the gear 25, several half gears 22 drive the winding drum 26 fixed on it to rotate through the gear 25. The rotation of the winding drum 26 winds up the suspension rope 27 fixed at one end, so that the breaker hammer 212 fixed to the end of the suspension rope 27 is pulled upward and lifted in the slide groove 211 by the limiting support of the second fixing rod 28 and the pulley 29. The sawtooth on the half gear 22 is designed to be half-toothed, so that when a half gear 22 meshes with the gear 25 and the sawtooth is finished, the arc-shaped side faces the gear 25, so that the gear 25 is not Under the action of the engagement limit, the breaker 212, under the action of gravity, drives the breaker 27 wound on the take-up drum 26 to pull out and straighten. With the help of the spring elastic potential energy and gravitational potential energy of the auxiliary mechanism 3, the breaker 212 is smashed onto the road surface, impacting the road surface and breaking it. The half gears 22 are designed to face opposite directions and be arranged in a staggered manner, so that several breaker hammers 212 smash onto the road surface in an alternating manner, ensuring the balanced operation of the device. The motor 23 drives the rotating shaft 21 to rotate, which drives the staggered and opposite-directed half gears 22. Under the pull of the breaker rope 27, several breaker hammers 212 continuously rise and fall in an alternating manner to smash the road surface, breaking it up. This not only ensures that the impact points are evenly distributed during the operation of the device, but the staggered operation can also disperse the direct impact force of the breaker hammers 212 rising and falling on the device, reducing wear and tear on the equipment and extending its service life to a certain extent.

[0034] By setting up auxiliary mechanism 3, when the crushing mechanism 2 drives the breaker 212 to rise in the chute 211, the breaker 212 drives the slider 37 to compress the spring 38 under the limit of the limit rod 36. This allows the breaker 212 to fall with gravity when the crushing mechanism 2 releases it. Combined with the elastic recovery of the spring 38, the elastic potential energy and gravitational potential energy act on the breaker 212 together, enhancing its impact on the ground to a certain extent. After the crushing mechanism 2 completes the crushing of the ground, the resulting blocky gravel is further crushed by the roller 32 under the support of the protrusion 33 and the receiving frame 31, forming smaller particles that are spread on the road surface for subsequent maintenance. The road surface reconstruction includes the installation of a brush guardrail 34, which reduces the amount of dust that may be stirred up when the breaker hammer 212 of the crushing mechanism 2 strikes the ground, thus preventing dust from entering the outside air. The system utilizes the elastic force of the spring 38, which, in conjunction with the crushing mechanism 2, drives the breaker hammer 212 upwards. By compressing the spring 38, some mechanical energy is stored. After the suspension rope 27 is released, the spring 38 returns to its original state, releasing its force through the slider 37, which is then applied to the breaker hammer 212. This, combined with gravity impact, breaks up the road surface. Compared to using only gravity impact, the combination of elastic force and gravity increases kinetic energy to a certain extent, further enhancing the impact force of the device on the road surface. This facilitates better completion of road surface breaking operations and further improves the practicality of the device.
