Description

Technical Field

[0001] This utility model belongs to the field of road construction, specifically a concrete road paving device. Background Technology

[0002] Concrete pavement paving is a crucial step in road construction, and its quality directly affects the road's performance and lifespan. During concrete pavement paving, specialized paving equipment is required to evenly spread the concrete on the road surface, ensuring a certain degree of flatness and thickness.

[0003] A paving system typically consists of a traction mechanism and a paving mechanism. The traction mechanism, usually a tractor unit, provides the power for the entire paving system, propelling it across the road surface. The paving mechanism is responsible for spreading and initially leveling the concrete. Its core component is the paving slab assembly, and factors such as the shape, size, position, and angle of the paving slab assembly significantly impact the paving quality.

[0004] Currently, while existing concrete pavement pavers on the market have achieved height adjustment and orientation change functions to some extent, some pavers use simple mechanical structures for height adjustment. The adjustment process is not flexible enough, making it difficult to achieve precise height control and adapt quickly to the construction needs of roadbeds with different heights. This results in frequent machine stops for adjustments during construction, affecting construction efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a concrete pavement paving device to solve the issues of inflexible height adjustment, difficulty in precise control, and inability to quickly adapt to the construction needs of roadbeds at different heights in the prior art, thereby affecting construction efficiency.

[0006] Concrete pavement paving equipment, including a traction mechanism and a paving mechanism:

[0007] The traction mechanism includes a tractor unit, and a hydraulic landing gear is installed on one side of the tractor unit;

[0008] The paving mechanism includes a fixed frame assembly mounted on a hydraulic lifting frame, and a paving plate assembly is mounted on the fixed frame assembly.

[0009] The fixing frame assembly includes a fixing frame body and a set of outer support plates. The set of outer support plates are symmetrically installed on both sides of the fixing frame body via short columns. A set of positioning columns is also fixed between the fixing frame body and the outer support plates. A positioning rod is also slidably embedded in the fixing frame body. A spring is fixed to one end of the positioning rod, and a push block is fixed to the outside of the positioning rod.

[0010] The paving slab assembly includes a U-shaped frame, on one side of which a paving slab is mounted, and a set of positioning grooves and positioning holes are symmetrically provided on the U-shaped frame;

[0011] The positioning rod is slidably embedded in the fixed frame body, and the spring drives the positioning rod to move and then abut against the outer support plate;

[0012] The positioning pin is embedded in the positioning groove, and the positioning rod passes through the positioning hole.

[0013] Preferably, the fixed frame body is provided with a guide rod inside, and the push block is slidably embedded in the guide rod.

[0014] Preferably, the outer support plate is a C-shaped reinforcing plate, and a group of the outer support plates are symmetrically fixed to both sides of the fixing frame body by short columns. The short columns are fixedly connected to the fixing frame body and the outer support plates by welding.

[0015] Preferably, the U-shaped frame and the paving slab are fixed together by welding.

[0016] Preferably, the hydraulic landing gear includes a hydraulic cylinder and a landing gear body. The landing gear body is hinged to the tractor vehicle, one end of the hydraulic cylinder is hinged to the tractor vehicle, and the other end of the hydraulic cylinder is hinged to the landing gear body.

[0017] The mounting frame assembly is mounted on the landing gear body;

[0018] The lifting and lowering of the fixed frame assembly is achieved by driving the landing gear body to rotate around the hinge point through the extension and retraction of hydraulic cylinder one.

[0019] Preferably, the landing gear body is also equipped with a second hydraulic cylinder for driving the fixed frame assembly to rotate;

[0020] When the piston rod of hydraulic cylinder two extends or retracts, it applies a torque to the fixed frame assembly, thereby driving the fixed frame assembly to rotate around its rotational connection point with the landing gear body, thus changing the paving orientation of the paving slab assembly.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The lifting frame body rotates around the hinge point by the extension and retraction of the hydraulic cylinder, thereby realizing the lifting and lowering of the fixed frame assembly and the paving mechanism. This allows the concrete pavement paving device to flexibly and accurately adjust the height of the paving plate assembly according to different construction scenarios and pavement height requirements, ensuring that it is always in the optimal working position. This greatly improves the adaptability and convenience of construction, effectively avoids paving quality problems caused by unsuitable height, and improves the flatness and uniformity of pavement.

[0023] By installing a hydraulic cylinder two on the landing gear body, the piston rod extends and retracts to apply torque to the fixed frame assembly, driving the fixed frame assembly to rotate around the rotational connection point with the landing gear body, thereby changing the paving orientation and angle of the paving slab assembly. This not only facilitates the paving slab assembly to operate at a suitable paving angle to meet the paving requirements of different road shapes and orientations, but also allows workers to easily clean the paving slab during construction breaks, reducing the impact of concrete residue on subsequent paving quality, and further improving construction efficiency and paving quality.

[0032] 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.

[0033] like Figures 1 to 6As shown:

[0034] Example 1: This utility model provides a concrete pavement paving device, including a traction mechanism 1 and a paving mechanism 2:

[0035] The traction mechanism 1 includes a tractor 11, and a hydraulic landing gear 12 is installed on one side of the tractor 11.

[0036] like Figure 2 As shown, the paving mechanism 2 includes a fixed frame assembly 21 mounted on the hydraulic lifting frame 12, and a paving plate assembly 22 is mounted on the fixed frame assembly 21;

[0037] like Figure 4 As shown, the fixing frame assembly 21 includes a fixing frame body 211 and a set of outer support plates 212. The set of outer support plates 212 are symmetrically installed on both sides of the fixing frame body 211 via short columns. A set of positioning columns 213 are also fixed between the fixing frame body 211 and the outer support plates 212. A positioning rod 214 is also slidably embedded in the fixing frame body 211. A spring 215 is fixed to one end of the positioning rod 214. A push block 216 is also fixed to the outside of the positioning rod 214.

[0038] like Figure 3 and Figure 6 As shown, the paving slab assembly 22 includes a U-shaped frame 221, on one side of which a paving slab 222 is installed. A set of positioning grooves 223 and positioning holes 224 are symmetrically opened on the U-shaped frame 221.

[0039] like Figure 5 As shown, the positioning rod 214 is slidably embedded in the fixed frame body 211, and the spring 215 drives the positioning rod 214 to move and then abut against the outer support plate 212;

[0040] The positioning pin 213 is embedded in the positioning groove 223, and the positioning rod 214 passes through the positioning hole 224.

[0041] Specifically, such as Figure 5 As shown, a guide rod is provided inside the fixed frame body 211, and the push block 216 is slidably embedded in the guide rod.

[0042] Specifically, such as Figure 4 As shown, the outer support plate 212 is a C-shaped reinforcing plate. A set of outer support plates 212 are symmetrically fixed to both sides of the fixing frame body 211 by short columns. The short columns are fixedly connected to the fixing frame body 211 and the outer support plates 212 by welding.

[0043] Specifically, the U-shaped frame 221 and the paving plate 222 are fixed together by welding.

[0044] As can be seen from the above, during operation, the tractor 11 serves as the power source, driving the entire device to move. The hydraulic lifting frame 12 installed on one side can flexibly adjust its height to adapt to the needs of different construction scenarios, ensuring that the paving mechanism 2 is in a suitable working position, providing stable support for subsequent paving operations, and greatly improving the convenience and flexibility of construction.

[0045] When the paving mechanism 2 is installed, the positioning rod 214 slides in the fixed frame body 211 and abuts against the outer support plate 212 under the drive of the spring 215. At the same time, the positioning column 213 is inserted into the positioning groove 223 and the positioning rod 214 passes through the positioning hole 224. This structure allows the paving plate assembly 22 to be stably installed on the fixed frame assembly 21.

[0046] By pushing the push block 216, the positioning rod 214 can be moved, which facilitates the installation and disassembly of the paving slab assembly 22, greatly improving the replacement efficiency. Workers can replace the paving slab assembly 22 with one of appropriate length according to actual needs.

[0047] like Figure 7 As shown:

[0048] Example 2: This example is basically the same as the previous example, except that the hydraulic landing gear 12 includes a hydraulic cylinder 121 and a landing gear body 122. The landing gear body 122 is hinged to the tractor 11, one end of the hydraulic cylinder 121 is hinged to the tractor 11, and the other end of the hydraulic cylinder 121 is hinged to the landing gear body 122.

[0049] The mounting bracket assembly 21 is mounted on the landing gear body 122;

[0050] The lifting and lowering action of the fixed frame assembly 21 is achieved by driving the landing gear body 122 to rotate around the hinge point through the extension and retraction of the hydraulic cylinder 121.

[0051] Specifically, a hydraulic cylinder 123 for driving the fixed frame assembly 21 to rotate is also installed on the landing gear body 122. The fixed frame assembly 21 can also be rotated around the landing gear body 122 by a motor drive.

[0052] When the piston rod of hydraulic cylinder 2 123 extends or retracts, it applies a torque to the fixed frame assembly 21, thereby driving the fixed frame assembly 21 to rotate around its rotational connection point with the landing gear body 122, thereby changing the paving orientation of the paving slab assembly 22.

[0053] As can be seen from the above, during operation, hydraulic cylinder 121 begins to function. Through its structure, which is hinged at one end to the tractor 11 and at the other end to the landing gear body 122, it drives the landing gear body 122 to rotate around the hinge point with the tractor 11 during extension and retraction, thereby realizing the lifting and lowering action of the fixed frame assembly 21. This allows the paving mechanism 2 to flexibly adjust its own height according to different construction scenarios and road height requirements, ensuring that the paving plate assembly 22 is in the optimal working position, effectively improving the adaptability and convenience of construction.

[0054] When it is necessary to rotate the paving plate assembly 22, the piston rod of the hydraulic cylinder 123 is extended or retracted, thereby applying a torque to the fixing frame assembly 21, causing the fixing frame assembly 21 to rotate around its rotational connection point with the landing gear body 122; as the fixing frame assembly 21 rotates, the angle of the paving plate assembly 22 installed on it also changes, thereby facilitating it to be in a suitable paving angle, and also facilitating the workers to clean the paving plate 222.

[0055] The embodiments of this utility model are given for the purpose of illustration and description. Although the embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Any changes, modifications, substitutions and variations made by those skilled in the art to the above embodiments within the scope of this utility model should be included within the protection scope of this utility model.
