Description

Technical Field

[0001] This utility model belongs to the field of municipal road paving technology, specifically relating to a municipal road paving structure. Background Technology

[0002] Municipal road paving is an important part of urban infrastructure construction, involving multiple stages and the selection of various materials. The laying and leveling of asphalt is one of the crucial stages in municipal road paving.

[0003] Chinese patent document with authorization announcement number CN222251610U discloses a municipal road paving structure, which adjusts the distance between two adjusting push plates a by rotating screw b with a handle. By rotating screw a with a handwheel, the adjusting push plate b can drive the two adjusting push plates a to rise and fall, so that the paving structure can be manually moved to spread asphalt of different widths and heights.

[0004] However, in the existing technology, the paving structure has a relatively fixed paving direction for asphalt. When it is necessary to pave asphalt evenly in multiple directions, construction workers often need to move the paving structure back and forth in multiple locations to complete the paving operation. Therefore, a paving structure for municipal roads is proposed. Utility Model Content

[0006] The technical solution adopted in this utility model is as follows:

[0007] A municipal road paving structure includes a pushing component that allows the structure to be moved conveniently and stably, an adjusting component that allows the direction of asphalt paving to be changed as needed, and a paving component that can contact the asphalt at a certain height and spread it out and flatten it is provided below the adjusting component.

[0008] The pushing assembly includes a frame, with two first axle seats fixedly installed at the front and rear of the frame, and a first rotating shaft movably connected between adjacent first axle seats;

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] like Figures 1-5 As shown, a municipal road paving structure includes a pushing component 1 that allows the structure to be moved conveniently and stably. The pushing component 1 is provided with an adjusting component 2 that allows the direction of asphalt paving on the structure to be changed as needed.

[0032] The first axle seat 103 is rotatably connected to the first rotating shaft 104; the frame 101 provides installation positions for components such as the handrail frame 102 and the locking seat 201; the handrail frame 102 allows construction personnel to easily push the frame 101; the first rotating shaft 104 with rollers 105 is installed inside the frame 101 through the first axle seat 103; the rollers 105, which can rotate together with the first rotating shaft 104, make the frame 101 easy to move; the protective shell 106 provides protection for components such as the pulley 207 of the adjustment assembly 2, which are located outside the main body of the frame 101; and the anti-tilt wheel assembly 107 improves the stability of the frame 101.

[0033] In this embodiment: the adjusting component 2 includes a rotating component that can be installed on the paving component 3 and orient it in a variable direction, a transmission component that can drive the paving component 3 to rotate when the structure moves, and a limiting component that can pave asphalt in a fixed direction for the paving component 3.

[0034] The rotating component includes two locking seats 201 fixedly installed inside the frame 101, with a turntable 202 movably mounted between the two locking seats 201. The transmission component includes a spline sleeve 211 disposed above the turntable 202. The transmission component also includes a second axle seat 203 fixedly installed above the frame 101, with a second rotating shaft 204 movably connected between the second axle seats 203. A third axle seat 205 is fixedly installed inside the frame 101, with a spline shaft 206 movably connected inside the third axle seat 205. The front end of the second rotating shaft 204 and its... Each of the first rotating shafts 104 has a pulley 207 fixedly connected to its front end, and a belt 208 is provided between the pulleys 207. The second rotating shaft 204 has a first bevel gear 209 fixedly connected to its rear end. The spline shaft 206 has a second bevel gear 210 fixedly connected to its upper end, and a spline sleeve 211 movably connected to its lower end. The limiting component includes a limiting block 212 fixedly installed in the frame 101. A positioning rod 213 is provided inside the limiting block 212 and passes through it. A knob 214 is fixedly connected to one end of the positioning rod 213.

[0035] The locking seat 201 is rotatably connected to the turntable 202. The turntable 202 and the spline sleeve 211 are both provided with the same number and diameter of screw holes. The second shaft seat 203 is rotatably connected to the second rotating shaft 204. The third shaft seat 205 is rotatably connected to the spline shaft 206. The first bevel gear 209 is meshed with the second bevel gear 210. The spline shaft 206 is slidably connected to the spline sleeve 211. The turntable 202 is integrally formed with a positioning hole. The turntable 202 is slidably connected to the positioning rod 213. The limit block 212 is connected to the positioning rod 213 by a thread.

[0036] The turntable 202 is installed in a fixed position within the frame 101 via the locking seat 201, allowing it to rotate under external force. The turntable 202 is used to install the upright 301, the second shaft 204 is installed via the second shaft seat 203, and the spline shaft 206 is installed via the third shaft seat 205. The arrangement of pulley 207, belt 208, second shaft 204, first bevel gear 209, second bevel gear 210, and spline shaft 206 allows the rotation of the first shaft 104 connected to the pulley 207 to be synchronously transmitted to the spline shaft 206 after a change of direction, enabling the spline shaft 206 to drive the spline sleeve 211 to rotate. The positioning rod 213 can be easily rotated via the knob 214, allowing it to move longitudinally relative to the limit block 212. The positioning rod 213, which can be inserted into the positioning hole of the turntable 202, restricts the rotation of the turntable 202 relative to the locking seat 201.

[0037] In this embodiment: the paving component 3 includes two uprights 301 set on the turntable 202. The upper end of the uprights 301 is movably connected to a handle 302, the lower end of the uprights 301 is movably connected to a connector 303, and a paving plate 304 is fixedly connected below the connector 303.

[0038] The turntable 202 is connected to the upright 301 by a thread, the upright 301 is slidably connected to the handle 302, and the upright 301 is rotatably connected to the connector 303.

[0039] The upright pole 301 can be easily rotated by the handle 302, so that the upright pole 301 can be raised and lowered relative to the turntable 202. The paving slab 304, which can contact and spread asphalt, can be raised and lowered together with the upright pole 301 as it is raised and lowered due to rotation, through the connector 303.

[0040] Working principle: When this structure is installed and used for municipal road paving, the construction workers will move the frame 101 by pushing it with the handrail 102, which will cause the first rotating shaft 104 and the roller 105 to rotate together. The rotation of one of the first rotating shafts 104 will be transmitted to the spline sleeve 211 through the pulley 207 connected to it and other components. In addition, when the positioning rod 213 is inserted into the positioning hole of the turntable 202, the rotation of the turntable 202 will be restricted.

[0041] Based on this, if the orientation of the paving plate 304 is not the same as the moving direction of this structure, the orientation of the paving plate 304 can be adjusted and the positioning rod 213 can be rotated to insert it into the positioning hole of the turntable 202 when the turntable 202 and the spline sleeve 211 are only in surface contact. If the paving plate 304 needs to rotate continuously when this structure moves, the two can be stably connected by bolts that match the screw holes of the turntable 202 and the spline sleeve 211. After that, the paving plate 304 will rotate at a certain speed when this structure moves.

[0042] Therefore, the orientation of the paving slab 304 can be flexibly adjusted and fixed according to the needs of asphalt paving, and can also be continuously changed when the structure moves, so as to pave asphalt more evenly in the required direction or manner.

[0043] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
