Description

Technical Field

[0001] This utility model relates to the field of paver technology, and in particular to an intelligent lifting canopy for a paver. Background Technology

[0002] A paver is a construction device mainly used for paving various materials for the base and surface layers of highways. It mainly includes a walking system, a hydraulic system, a material conveying system, and auxiliary systems. Among these, the paver canopy is a very important part of the auxiliary system. Its main function is to provide shade and rain protection for the operator's cab, thereby providing the operator with a good working space to better complete the road paving work.

[0003] During operation, pavers need to be transported by flatbed trucks. During transport, the height of the paver plus its canopy often exceeds traffic regulations. Therefore, the canopy needs to be retracted to comply with these regulations. However, current technology often relies on manual methods to raise and lower the canopy support, which is inefficient, time-consuming, and labor-intensive. Utility Model Content

[0004] This utility model provides an intelligent lifting canopy for a paver, which solves the problems of time-consuming, labor-intensive, and inefficient lifting of the paver canopy mentioned in the background art.

[0005] This utility model provides an intelligent lifting canopy for a paver, including a paver body, a chimney hinged to the front of the body, and a foundation canopy installed above the body. The foundation canopy includes a foundation canopy body and telescopic columns hinged to the four corners below the foundation canopy body. The two telescopic columns located at the front of the body are each connected to the body via a first connector, and the two telescopic columns located at the rear are each connected to the body via a second connector. Two horizontal beams are also arranged parallel to each other at the bottom of the foundation canopy body, and the horizontal beams are hinged to the chimney via connecting rods. A lifting electric push rod is also installed at the rear of the body, with its output end hinged to the second connector and its other end hinged to the body. An extension canopy is also installed below the foundation canopy, and a control component is also provided on the body.

[0006] Optionally, the second connecting member includes a support with a hollow internal structure and a connecting plate disposed between the two inner side walls of the support. Two L-shaped connecting rods are symmetrically arranged on the side of the connecting plate near the inside of the support. The long side of the L-shaped connecting rod is hinged to the support, and the short side is hinged to the output end of the lifting electric push rod. A fixing rod is also provided on the connecting plate, and two telescopic columns at the rear of the machine body are fixedly connected to the connecting plate through the fixing rod.

[0007] Optionally, a pin is used as the connecting element when hinged.

[0008] Optionally, the first connector includes a U-shaped base fixed to the machine body. The two side plates of the U-shaped base have mounting holes, and a rotating shaft is provided in the mounting holes. The telescopic column at the front of the machine body is rotatably connected to the U-shaped base through the rotating shaft.

[0009] Alternatively, the crossbeams may be parallel to the shorter side of the foundation canopy.

[0010] Optionally, the extended canopy includes two extended canopy bodies and two extended electric actuators. The fixed end of each extended electric actuator is fixedly installed on a crossbeam, and the output end is fixedly installed on the extended canopy body. The two crossbeams are also equipped with slide rails for the extended canopy bodies to slide on, and the extended canopy bodies are slidably connected to the slide rails. The two short sides of the base canopy body are also provided with grooves for the extension and retraction of the extended canopy bodies.

[0011] Optionally, the extension electric actuator installed on each extension canopy has its fixed end mounted on a crossbeam away from the extension canopy.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this utility model.

[0028] like Figure 1-6 As shown, this utility model provides an intelligent lifting canopy for a paver, including a paver body 2. A chimney 21 is hinged to the front of the body 2. A foundation canopy 1 is also installed above the body 2. The foundation canopy 1 includes a foundation canopy 11 and telescopic columns 12 hinged to the four corners below the foundation canopy 11. The two telescopic columns 12 located at the front of the body 2 are each connected to the body 2 through a first connector 13, and the two telescopic columns 12 located at the rear are each connected to the body 2 through a second connector 14. Two crossbeams 15 are also arranged parallel to each other at the bottom of the foundation canopy 11. The crossbeams 15 are hinged to the chimney 21 through connecting rods 16. A lifting electric push rod 17 is also installed at the rear of the body 2. The output end of the lifting electric push rod 17 is hinged to the second connector 14, and the other end is hinged to the body 2. An extension canopy 3 is also installed below the foundation canopy 1. A control component is also provided on the body 2.

[0029] When the paver's intelligent lifting canopy is in use, the control component intelligently controls various parts of the canopy. The specific lifting process is as follows: When the canopy needs to be raised, the control component issues a lifting command. Then, the lifting electric push rod 17 extends and pushes the second connecting member 14. The second connecting member 14 then drives the telescopic columns 12 from a horizontal state to a vertical state. The two telescopic columns 12 connected to the second connecting member 14 drive the base canopy 11 from its original transport state (i.e.,...). Figure 1 The state shown by the light-colored lines at the lower position changes to the unfolded working state located directly above the unit 2 (i.e., Figure 1 (The dark lines indicate the higher position). The rising base canopy 11 causes the two telescopic columns 12, located in front of the machine body 2 and connected to the first connecting piece 13, to also become vertical. When the base canopy 1 is fully in the working position, the extension canopy 3 can be further extended to expand the area of ​​the entire canopy for sunshade and rain protection. During the process of the base canopy 11 rising to the working state, the crossbeam 15 below it drives the chimney 21 to change from the original transport state to the vertical state through the connecting rod 16.

[0030] When the paver needs to be transported, the canopy needs to be switched from a vertical working state to a transport state. The canopy lowering process is as follows: the control component issues a lowering command, then the extended canopy 3 retracts, and then the lifting electric push rod 17 is also retracted. The retracted lifting electric push rod 17 drives the second connecting member 14 to rotate, and the second connecting member 14 drives the two telescopic columns 12 connected to it to return from the vertical state to the horizontal state. The telescopic column 12 connected to the first connecting member 13 also rotates to the horizontal state. During the process of the telescopic column 12 returning to the initial position, the base canopy 11 and the chimney 21 also return to the initial transport state.

[0031] The intelligent lifting canopy for pavers provided by this utility model achieves rapid conversion of the canopy from transportation state to working state through the integrated design of the basic canopy 1, the telescopic columns 12 hinged at the four corners, the lifting electric push rod 17, the extension canopy 3, and the control components. This reduces the intensity of manual operation and improves the lifting efficiency.

[0032] like Figure 5 and Figure 6 As shown, the second connecting member 14 further includes a support 141 with a hollow internal structure and a connecting plate 142 disposed between the two inner side walls of the support 141. Two L-shaped connecting rods 143 are symmetrically arranged on the side of the connecting plate 142 near the interior of the support 141. The long side of the L-shaped connecting rod 143 is hinged to the support 141, and the short side is hinged to the output end of the lifting electric push rod 17. A fixing rod 144 is also provided on the connecting plate 142, and the two telescopic columns 12 at the rear of the machine body 2 are fixedly connected to the connecting plate 142 through the fixing rod 144. Furthermore, the connecting member used for hinged connection is a pin 18.

[0033] The process of the lifting electric actuator 17 driving the second connecting member 14 and the corresponding telescopic column 12 to lift is as follows: The output end of the lifting electric actuator 17 extends, pushing the short side of the L-shaped connecting rod 143 upward, causing the L-shaped connecting rod 143 to rotate around the pin 18 mounted on the second connecting member 14. The L-shaped connecting rod 143 then drives the connecting plate 142 fixed on it to rotate, and finally the connecting plate 142 drives the corresponding telescopic column 12 to rise through the fixed rod 144. The process of lowering is the reverse of the lifting process and will not be described in detail here.

[0034] It should be noted that the connecting plate 142 is fixedly connected to the two L-shaped connecting rods 143. Figure 6 The diagram is presented in a disassembled manner to clearly illustrate its structure.

[0035] The linkage structure of the support 141, connecting plate 142, and L-shaped connecting rod 143 of the second connector 14 ensures stable transmission between the lifting electric push rod 17 and the telescopic column 12, thereby enhancing the mechanical reliability of the canopy lifting process. Connecting the various hinged parts via pins 18 simplifies the structural assembly and maintenance process and reduces installation complexity.

[0036] like Figure 4 As shown, the first connector 13 further includes a U-shaped base 131 fixed on the body 2. The two side plates of the U-shaped base 131 are provided with mounting holes 132. A rotating shaft 133 is provided in the mounting holes 132. The telescopic column 12 at the front of the body 2 is rotatably connected to the U-shaped base 131 through the rotating shaft 133.

[0037] The telescopic column 12 installed on the first connector 13 is rotatably connected to the U-shaped base 131 via the pivot 133. When the base canopy 11 is lifted by the telescopic column 12 installed on the second connector 14, the base canopy 11 will then drive the telescopic column 12 installed on the first connector 13 to move to a vertical position, thereby providing support for the base canopy 11.

[0038] The U-shaped base 131 and the rotating shaft 133 of the first connector 13 enable flexible rotational support of the front telescopic column 12, thereby improving the stability of the front structure during the lifting and lowering of the base canopy 1.

[0039] like Figure 2 As shown, the crossbeam 15 is parallel to the short side of the base canopy 11. Furthermore, the extended canopy 3 includes two extended canopies 31 and two extended electric actuators 32. The fixed end of each extended electric actuator 32 is fixedly mounted on a crossbeam 15, and the output end is fixedly mounted on an extended canopy 31. Slide rails 33 are also mounted on the two crossbeams 15 for sliding the extended canopies 31, and the extended canopies 31 are slidably connected to the slide rails 33. Grooves 34 for extending and retracting the extended canopies 31 are also provided on the two short sides of the base canopy 11.

[0040] Once the base canopy 11 is raised to the designated position, the extension canopy 3 can be deployed to further increase the area of ​​the canopy for sun and rain protection. The deployment process is as follows: the extension electric actuator 32 is activated, pushing the extension canopy 31 to slide along the slide rail 33 and extend out of the base canopy 11 from the groove 34. During the process of the extension electric actuator 32 pushing the extension canopy 31, the deployment area of ​​the extension canopy 31 can be determined according to the specific usage environment.

[0041] By extending the canopy 3 with its sliding rail 33, extending electric push rod 32, and groove 34, the canopy 31 can be smoothly extended and retracted, thus flexibly expanding the shading area and adapting to the needs of different construction scenarios.

[0042] like Figure 2 As shown, further, the extension electric actuator 32 installed on each extension canopy 31 has its fixed end installed on the crossbeam 15 away from the extension canopy 31.

[0043] The fixed end of the extension electric actuator 32 on each extension tent 31 is installed on the crossbeam 15 away from the extension tent 31, thereby increasing the installation area of ​​the corresponding extension tent 31, that is, increasing the area of ​​the installable extension tent 31, so that the area covered by the subsequent extension tent 31 after it is unfolded is larger.

[0044] Furthermore, the four telescopic columns 12 include two electric actuator supports and two non-powered supports. Furthermore, the two telescopic columns 12 connected to the second connector 14 are electric actuator supports.

[0045] The two telescopic columns 12 connected to the second connector 14 are set as electric push rod supports. When all four telescopic columns 12 are in a vertical state, the two electric push rod supports are activated, causing the base canopy 11 to rise, thereby increasing the operating space for workers and improving their ease of operation.

[0046] Furthermore, the control components include: a main controller integrated into the body 2 for providing power and coordinating the action logic of each structure; a control box for receiving instructions and distributing signals to each structure; and a manual controller for sending lifting instructions.

[0047] The control components can be purchased commercially, which is well known to those skilled in the art, and will not be described in detail here.

[0048] The complete working principle of the intelligent lifting canopy for the paver provided by this utility model is as follows:

[0049] like Figure 1-6 As shown, the intelligent lifting canopy of the paver is used as follows: The control component intelligently controls each part of the canopy. The specific lifting process is as follows: When the canopy needs to be raised, the control component issues a lifting command. Then, the lifting electric push rod 17 extends and pushes the short side of the L-shaped connecting rod 143 upwards, causing the L-shaped connecting rod 143 to rotate around the pin 18 mounted on the second connecting member 14. The L-shaped connecting rod 143 then drives the fixed connecting plate 142 to rotate, and finally, the connecting plate 142, through the fixed rod 144, drives the corresponding telescopic column 12 from a horizontal state to a vertical state. At this time, the two telescopic columns 12 connected to the second connecting member 14 drive the basic canopy 11 from its original transport state to an unfolded working state located directly above the machine body 2. During the upward movement of the basic canopy 11, it will also drive the telescopic column 12 mounted on the first connecting member 13 to move to a vertical state, thus providing support for the basic canopy 11. During the process of the basic canopy 11 being raised to the working state, the crossbeam 15 below it drives the chimney 21 to change from the original transport state to the vertical state through the connecting rod 16.

[0050] Once all four telescopic columns 12 are in a vertical position, activate the two electric push rod supports to raise the base canopy 11 to the designated position. Then activate the extension electric push rod 32 to push the extension canopy 31 to slide along the slide rail 33 and extend from the base canopy 11 through the groove 34 to increase the canopy's coverage area.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
