Description

Technical Field

[0001] The present application relates to the technical field of pavement laying equipment, and particularly relates to a self-cleaning polyurethane concrete paving device and a paver truck. Background Art

[0002] A paver is a construction equipment mainly used for paving operations of various materials on the base course and surface course of roads, and the paving work is completed by the cooperation of various different systems. The existing paving work process starts with the initial feeding of materials by a feeder or an excavator on the road, that is, the raw materials are initially arranged on the road surface passed by the paving device, and then the mixture in front of the paving device is evenly mixed by a spiral feeder or a plow.

[0003] In the related art, polyurethane concrete, which is formed by the reaction of isocyanate and polyol as a binder, has the characteristics of fast curing speed, high road performance, good durability, and thin paving layer thickness, and has become another new high-performance paving material in addition to asphalt-based and UHPC-based steel bridge deck pavings. The rapid forming of polyurethane concrete has made great contributions to shortening the opening time of large urban steel bridges to traffic.

[0004] However, this has also become a disadvantage of polyurethane concrete paving materials - the construction time is too short. Due to the limitation of the traditional paver feeding method, polyurethane concrete cannot perform a series of operations such as mixing, stirring, and paving in a short time, resulting in the condensation of polyurethane concrete in the paving device, seriously affecting the progress of the steel bridge deck paving project, and manual cleaning of the paver will also consume a large amount of manpower. Therefore, it is very necessary to manufacture a special integrated paving device for polyurethane concrete that can integrate feeding, mixing, stirring, and paving and can realize the self-cleaning function to promote the use of polyurethane concrete materials for steel bridge deck pavings.

Detailed implementation manners

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0033] The embodiments of the present application provide a self-cleaning polyurethane concrete paving device and a paving vehicle, which can solve the problems that in the related art, the paver cannot quickly distribute polyurethane concrete and the cleaning is time-consuming and laborious.

[0034] See Figures 1 to 6 As shown in the figure, in the first aspect of the embodiments of the present application, a self-cleaning polyurethane concrete paving device is provided, including:

[0035] A feeding housing 1, on which a feeding port 1-2 and a discharging port 1-3 for polyurethane concrete to pass through are provided;

[0036] A cloth feeding mechanism 2, the cloth feeding mechanism 2 includes an auger 2-2 arranged at the discharging port 1-3;

[0037] A pushing mechanism, the pushing mechanism includes an arc-shaped pushing block 3 arranged in the feeding housing 1 and a displacement assembly 1-6 for driving the arc-shaped pushing block 3 to reciprocate. The displacement assembly 1-6 can drive the arc-shaped pushing block 3 to approach and fit the auger 2-2 so that the auger 2-2 scrapes the arc-shaped pushing block 3.

[0038] On the feeding housing 1 of the self-cleaning polyurethane concrete paving device according to the embodiment of the present application, a cloth feeding mechanism 2 and a material pushing mechanism are provided. The feeding housing 1 is provided with a feeding port 1-2 and a discharging port 1-3 for the passage of polyurethane concrete. The cloth feeding mechanism 2 includes a auger 2-2 arranged at the discharging port 1-3. The material pushing mechanism includes an arc-shaped material pushing block 3 arranged in the feeding housing 1 and a displacement assembly 1-6 for driving the arc-shaped material pushing block 3 to reciprocate. The displacement assembly 1-6 can drive the arc-shaped material pushing block 3 to approach and fit against the auger 2-2 so that the auger 2-2 scrapes the arc-shaped material pushing block 3.

[0039] During specific use, by mounting the paving device on a mobile device, the arc-shaped material pushing block 3 is driven by the displacement assembly 1-6 to move away from the discharging port 1-3, ensuring that all the polyurethane concrete raw materials fed from the feeding port 1-2 can smoothly enter the feeding housing 1. By driving the arc-shaped material pushing block 3 to approach the discharging port 1-3 through the displacement assembly 1-6, the arc-shaped material pushing block 3 pushes all the polyurethane concrete raw materials in the feeding housing 1 forward towards the rotating auger 2-2. The rotating auger 2-2 quickly mixes and stirs the polyurethane concrete raw materials. At the same time, the mobile device drives the paving device to move, and the mixed and stirred polyurethane concrete is continuously pushed out for paving on the road surface, thereby achieving the purpose of rapid cloth feeding. At the same time, when the arc-shaped material pushing block 3 approaches and fits against the rotating auger 2-2, the rotating auger 2-2 scrapes off the residual polyurethane concrete at the front end of the arc-shaped material pushing block 3, saving the manpower and material resources for manual cleaning of the paving device, thus achieving the purpose of integrating feeding, mixing, stirring, and paving, and can achieve the effect of self-cleaning function, which is beneficial to the popularization of polyurethane concrete materials for steel bridge deck paving.

[0040] In some alternative embodiments: Refer to Figures 1 to 3 As shown, the embodiment of the present application provides a self-cleaning polyurethane concrete paving device. One side of the feeding housing 1 of the self-cleaning polyurethane concrete paving device close to the feeding port 1-2 extends towards the auger 2-2 to form an arc-shaped flange.

[0041] One side of the feeding housing 1 of the self-cleaning polyurethane concrete paving device according to the embodiment of the present application close to the feeding port 1-2 extends towards the auger 2-2 to form an arc-shaped flange. The arc-shaped flange and the discharging port 1-3 cooperate to form a mixing bin that semi-wraps the auger 2-2.

[0042] During specific use, the arc-shaped material pushing block 3 pushes all the polyurethane concrete raw materials in the feeding housing 1 forward into the mixing bin, so that the polyurethane concrete raw materials can be quickly mixed and stirred in the mixing bin and then pushed out for paving on the road surface. The arc-shaped flange can concentrate the raw materials to a certain extent, ensure the mixing and stirring effect, and prevent the raw materials from splashing onto the top of the feeding housing 1.

[0043] In some alternative embodiments: Refer to Figures 1 to 3As shown in the figure, an embodiment of the present application provides a self-cleaning polyurethane concrete paving device. The feeding mechanism 2 of the self-cleaning polyurethane concrete paving device further includes a first motor 2-1 for driving the auger 2-2 to rotate. The first motor 2-1 is rotatably connected to the feeding housing 1 through a machine base;

[0044] It further includes a pulling mechanism 4. The pulling mechanism 4 can drive the auger 2-2 to approach and fit against the arc-shaped flange so that the auger 2-2 scrapes the arc-shaped flange.

[0045] The feeding mechanism 2 of the self-cleaning polyurethane concrete paving device according to the embodiment of the present application further includes a first motor 2-1 for driving the auger 2-2 to rotate. The first motor 2-1 is rotatably connected to the feeding housing 1 through a machine base; it further includes a pulling mechanism 4. The pulling mechanism 4 can drive the auger 2-2 to approach and fit against the arc-shaped flange so that the auger 2-2 scrapes the arc-shaped flange. In the embodiment of the present application, the pulling mechanism 4 can be an electric cylinder arranged between the feeding housing 1 and the auger 2-2. One end of the electric cylinder is rotatably connected to the end of the auger 2-2, and the other end is rotatably connected to the feeding housing 1.

[0046] During specific use, the arc-shaped flange and the discharge port 1-3 cooperate to form a mixing bin that semi-wraps the auger 2-2. The first motor 2-1 drives the auger 2-2 to rotate, so as to quickly stir and mix the polyurethane concrete raw materials pushed to the mixing bin by the arc-shaped pushing block 3. Through the pulling mechanism 4, the auger 2-2 and the first motor 2-1 can be driven to deflect around the feeding housing 1 towards the arc-shaped flange, so that the rotating auger 2-2 can approach and fit against the arc-shaped flange, and scrape the residual polyurethane concrete on the inner surface of the arc-shaped flange, saving the manpower and material resources for manual cleaning of the paving device and realizing the self-cleaning function of the arc-shaped flange.

[0047] It should be noted that the first motor 2-1 can adopt a double-shaft extension motor. Both output ends on both sides of the double-shaft extension motor are connected to the auger 2-2. The blade spiral directions of the two augers 2-2 on both sides can be set in opposite directions to prevent the raw materials from shifting to one side during mixing and stirring, ensuring more uniform distribution of the raw material mixing; at the same time, after the first motor 2-1 adopts a double-shaft extension motor, the pulling mechanism 4 can be arranged on both sides of the feeding housing 1, which can synchronously drive the two augers 2-2 on both sides to approach and clean the inner surface of the arc-shaped flange, and further ensure more stable mixing and cleaning effects.

[0048] In some alternative embodiments: Refer to Figures 1 to 4 As shown in the figure, an embodiment of the present application provides a self-cleaning polyurethane concrete paving device. A strip-shaped guiding hole 1-1 is opened on the feeding housing 1 of the self-cleaning polyurethane concrete paving device. The pulling mechanism 4 includes a limiting rod 4-12 fixed on the arc-shaped pushing block 3 and passing through the strip-shaped guiding hole 1-1. A grasping and releasing assembly for grasping or releasing the end of the auger 2-2 is arranged on the limiting rod 4-12.

[0049] For the strip-shaped guiding hole 1-1 of the self-cleaning polyurethane concrete paving device according to the embodiment of the present application, the pulling mechanism 4 includes a limiting rod 4-12 disposed on the arc-shaped material pushing block 3 and passing through the strip-shaped guiding hole 1-1, and a grasping and releasing assembly for grasping or releasing the end of the auger 2-2 is arranged on the limiting rod 4-12.

[0050] During specific use, the displacement assembly 1-6 drives the arc-shaped material pushing block 3 to move. The arc-shaped material pushing block 3 drives the limiting rod 4-12 to move within the strip-shaped guiding hole 1-1. When the arc-shaped material pushing block 3 moves into contact with the auger 2-2, the limiting rod 4-12 restricted by the strip-shaped guiding hole 1-1 can limit the arc-shaped material pushing block 3, preventing the auger 2-2 from continuing to push forward, thereby protecting the normal stirring of the auger 2-2. When it is necessary to clean the inner surface of the arc-shaped flange, the end of the auger 2-2 is grasped by the grasping and releasing assembly, and then the arc-shaped material pushing block 3 is driven to move by the moving assembly. The arc-shaped material pushing block 3 drives the limiting rod 4-12 to move, and the limiting rod 4-12 drives the auger 2-2 and the first motor 2-1 to deflect around the feeding housing 1 towards the arc-shaped flange through the grasping and releasing assembly, so that the rotating auger 2-2 can approach and fit the arc-shaped flange to scrape the residual polyurethane concrete on the inner surface of the arc-shaped flange. After the scraping is completed, the end of the auger 2-2 is released by the grasping and releasing assembly, enabling the moving assembly to continue driving the arc-shaped material pushing block 3 away from the auger 2-2.

[0051] In some alternative embodiments: Refer to Figures 1 to 5 As shown, the embodiment of the present application provides a self-cleaning polyurethane concrete paving device. The grasping and releasing assembly of the self-cleaning polyurethane concrete paving device includes a second motor 4-4 fixed on the limiting rod 4-12. The output end of the second motor 4-4 is connected with a first gear 4-2 through a rotating shaft 4-11. A connecting frame 4-5 is connected between the rotating shaft 4-11 and the limiting rod 4-12. A second gear 4-3 meshing with the first gear 4-2 is rotatably connected to the connecting frame 4-5, and a semi-circular enclosure 4-32 for driving the auger 2-2 to move is arranged on the second gear 4-3.

[0052] The grasping and releasing assembly of the self-cleaning polyurethane concrete paving device according to the embodiment of the present application includes a second motor 4-4 fixed on the limiting rod 4-12. The output end of the second motor 4-4 is connected with a first gear 4-2 through a rotating shaft 4-11. A connecting frame 4-5 is connected between the rotating shaft 4-11 and the limiting rod 4-12. The connecting frame 4-5 is rotatably connected with a second gear 4-3 meshing with the first gear 4-2 through a short shaft 4-31, and a semi-circular enclosure 4-32 for driving the auger 2-2 to move is arranged on the second gear 4-3.

[0053] During specific use, when the arc-shaped pusher block 3 moves to contact the auger 2-2, the second motor 4-4 drives the first gear 4-2 to rotate through the rotating shaft 4-11. The first gear 4-2 drives the second gear 4-3 to rotate, and the second gear 4-3 drives the semi-circular enclosure 4-32 to deflect to an appropriate angle, so that the end of the auger 2-2 enters the inner side of the semi-circular enclosure 4-32, thereby realizing the grasping of the end of the auger 2-2. The inner side of the semi-circular enclosure 4-32 is a smooth surface, and at the same time, the auger 2-2 can rotate inside the semi-circular enclosure 4-32, and the semi-circular enclosure 4-32 does not affect the rotation of the auger 2-2;

[0054] Then, the moving component drives the arc-shaped pusher block 3 to move. The arc-shaped pusher block 3 drives the limit rod 4-12 to move. The limit rod 4-12 drives the auger 2-2 and the first motor 2-1 to deflect around the feeding machine housing 1 towards the arc-shaped flange through the semi-circular enclosure 4-32 which has an indirect connection relationship with it, so that the rotating auger 2-2 can approach and fit the arc-shaped flange, and scrape the residual polyurethane concrete on the inner surface of the arc-shaped flange;

[0055] After the inner surface of the arc-shaped flange is scraped, the second motor 4-4 controls the semi-circular enclosure 4-32 which has an indirect connection relationship with it to deflect by an appropriate angle again, so that the end of the auger 2-2 is separated from the inner side of the semi-circular enclosure 4-32, thereby realizing the release of the end of the auger 2-2, and enabling the moving component to continue driving the arc-shaped pusher block 3 away from the auger 2-2, facilitating the opening of the feeding port 1-2 for re-feeding.

[0056] It should be noted that strip-shaped guide holes 1-1 can be opened on both sides of the feeding machine housing 1. The limit rod 4-12 can pass through the two strip-shaped guide holes 1-1, thereby facilitating the setting of the grasping and releasing components on both sides of the feeding machine housing 1, realizing the synchronous grasping or release of the ends of the augers 2-2 on both sides, and ensuring that the augers 2-2 can stably deflect and approach the inner side of the arc-shaped flange.

[0057] It should be noted that when the grasping and releasing components are arranged on both sides of the feeding machine housing 1, the second motor 4-4 can be arranged on only one side. The rotating shaft 4-11 connected to the second motor 4-4 can penetrate the arc-shaped pusher block 3, so that the second motor 4-4 can drive the first gears 4-2 on both sides to rotate synchronously through the rotating shaft 4-11, and finally realize the grasping or release of the ends of the augers 2-2. At the same time, the second motor 4-4 can adopt a stepping motor, which is convenient for accurately controlling the moving angle of the semi-circular enclosure 4-32.

[0058] It should be noted that when the rotating shaft 4-11 connected to the second motor 4-4 penetrates through the arc-shaped pusher block 3, the length of the strip-shaped guide hole 1-1 needs to be appropriately extended to ensure that the rotating shaft 4-11 connected to the second motor 4-4 passes through the strip-shaped guide hole 1-1. If the rotating shaft 4-11 connected to the second motor 4-4 is closer to the discharge port 1-3 than the limit rod 4-12, the cooperation of the rotating shaft 4-11 and the strip-shaped guide hole 1-1 is used to limit the stop point where the arc-shaped pusher block 3 approaches the auger 2-2.

[0059] In some alternative embodiments: Refer to Figures 1 to 3 As shown, the embodiment of the present application provides a self-cleaning polyurethane concrete paving device. A T-shaped frame 1-7 extending above the auger 2-2 is fixed on the feeding housing 1 of the self-cleaning polyurethane concrete paving device. One end of the T-shaped frame 1-7 close to the auger 2-2 is hinged to the machine base through a pin, and a return spring 1-8 for driving the machine base to reset is arranged between the machine base and the T-shaped frame 1-7.

[0060] On the feeding housing 1 of the self-cleaning polyurethane concrete paving device of the embodiment of the present application, a T-shaped frame 1-7 extending above the auger 2-2 is fixed. One end of the T-shaped frame 1-7 close to the auger 2-2 is hinged to the machine base through a pin, and a return spring 1-8 for driving the machine base to reset is arranged between the machine base and the T-shaped frame 1-7.

[0061] During specific use, when the grasping mechanism grasps and drives the auger 2-2 close to the arc-shaped flange, the return spring 1-8 is deformed by force, so that the auger 2-2 can drive the first motor 2-1 and the machine base to deflect around the pin, ensuring that the auger 2-2 can deflect close to and fit the inner side of the arc-shaped flange for scraping.

[0062] After the grasping mechanism releases the end of the auger 2-2, the return spring 1-8 restores its deformation, so that the machine base drives the first motor 2-1 and the auger 2-2 to reset, ensuring that the auger 2-2 can continue to rotate normally after returning to its position and mix and stir the subsequent raw materials.

[0063] In some alternative embodiments: Refer to Figures 1 to 4 As shown, the embodiment of the present application provides a self-cleaning polyurethane concrete paving device. A guide rod 2-3 is fixed on one side of the feeding housing 1 of the self-cleaning polyurethane concrete paving device close to the auger 2-2. A guide groove is provided on the guide rod 2-3, and the end of the auger 2-2 passes through the guide groove.

[0064] On one side of the feeding housing 1 of the self-cleaning polyurethane concrete paving device of the embodiment of the present application, a guide rod 2-3 is provided. A guide groove is provided on the guide rod 2-3, and the end of the auger 2-2 passes through the guide groove.

[0065] During specific use, when the pulling mechanism 4 drives the auger 2-2 to deflect, the end of the auger 2-2 slides in the guiding groove. The guiding groove can limit the starting and ending points of the auger 2-2 when it deflects around the feeding housing 1. The end point of the guiding groove corresponds to the position when the auger 2-2 contacts the inner side of the arc-shaped flange. At the end point, the auger 2-2 cannot continue to approach the arc-shaped flange, thereby protecting the normal agitation of the auger 2-2.

[0066] It should be noted that when the first motor 2-1 is arranged in the middle of the feeding housing 1, guiding rods 2-3 can be fixedly installed at the ends of both augers 2-2.

[0067] In some alternative embodiments: Refer to Figure 1 and 6 As shown in

[0068] The displacement assembly 1-6 of the self-cleaning polyurethane concrete paving device in the embodiment of the present application includes a third motor 1-5 fixed on the feeding housing 1 and two mutually parallel racks 1-62. The side of the arc-shaped pushing block 3 away from the auger 2-2 is fixed to the two racks 1-62. The output end of the third motor 1-5 is fixed with a third gear 1-61 meshing with the rack 1-62 through a transmission shaft 1-64. A support block 1-63 rotatably connected to the transmission shaft 1-64 is fixed on the feeding housing 1.

[0069] During specific use, the third motor 1-5 drives the third gear 1-61 to move through the transmission shaft 1-64. The third gear 1-61 drives the arc-shaped pushing block 3 to move in the feeding housing 1 through the rack 1-62, thereby realizing the pushing of the raw materials in the feeding housing 1.

[0070] It should be noted that the third motor 1-5 can adopt a double-shaft extension motor. The output ends on both sides of the double-shaft extension motor are connected to the third gear 1-61 through the transmission shaft 1-64, ensuring that the third gears 1-61 on both sides can drive the rack 1-62 to move synchronously and stably, and further stably drive the arc-shaped pushing block 3 to move.

[0071] In some alternative embodiments: Refer to Figure 3 As shown in

[0072] The inner diameters of the arc-shaped material pushing block 3 and the arc-shaped flange of the self-cleaning polyurethane concrete paving device according to the embodiment of the present application are both equal to the diameter of the auger 2-2.

[0073] During specific use, it can ensure that the arc-shaped surfaces of the arc-shaped material pushing block 3 and the arc-shaped flange have the largest contact surface with the blades of the auger 2-2, thereby ensuring the scraping effect of the arc-shaped surfaces of the arc-shaped material pushing block 3 and the arc-shaped flange.

[0074] See Figures 1 to 6 As shown, the second aspect of the embodiment of the present application provides a paving vehicle, including:

[0075] The self-cleaning polyurethane concrete paving device of any one of the above embodiments.

[0076] The paving vehicle of the embodiment of the present application adopts the self-cleaning polyurethane concrete paving device of the above embodiment, which can realize the process of the arc-shaped material pushing block 3 retreating - feeding - the arc-shaped material pushing block 3 advancing - stirring - the arc-shaped material pushing block 3 driving the retreat of the auger 2-2 to complete the work of the entire paving device. During the entire movement process, the rapid feeding of the polyurethane concrete raw material and the self-cleaning function of the arc-shaped material pushing block 3 and the arc-shaped flange will be completed simultaneously, simplifying the complex structure of general paving equipment, cooperating to realize the rapid forming of polyurethane concrete, and eliminating the work of manually cleaning the mixing mechanism.
