Description

Technical Field

[0001] The present invention belongs to the technical field of pavers, and in particular relates to a high-speed paver. Background Art

[0002] A slip film paver is a device that can move along the paving direction on the surface and automatically spread concrete on the surface.

[0003] Conventional slipform paving machines typically include a pair of side forms that are used to maintain the shape and height of the finished concrete structure.

[0004] For example, patent document CN 112211073A discloses a slipform paver. It specifically discloses the following technical features: "A slipform paver device is configured to move across a ground surface in a paving direction for forming concrete into a finished concrete structure. The slipform paver device can include: a main frame; a slipform paver mold supported by the main frame; and at least one side formwork assembly configured to close the slipform paver mold on at least one side of the slipform paver mold to form a transverse concrete side surface on the finished concrete structure."

[0005] These types of slipsheet pavers present a practical problem in operation. The side panels move with the paver, and they cannot be removed before the concrete has lost its fluidity, otherwise the concrete will flow to either side of the paving direction. To address this, the paver is typically moved at an unusually slow speed, ensuring that the concrete will not resume moving until it has lost its fluidity. This results in slower paving speeds, and efficiency needs to be improved. Summary of the Invention

[0006] An embodiment of the present invention provides a high-speed paver to solve the problems in the prior art.

[0007] The embodiment of the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] A high-speed paver of the present invention includes a main frame 1 that can move along the paving direction. A funnel 2 is provided on the main frame 1 for carrying concrete and transporting concrete to the ground. A spiral feeding assembly 3, a vibrating assembly 4, a rotary smoothing assembly 5 and a roller smoothing assembly 6 are sequentially provided on the main frame 1 behind the funnel 2. Side formwork assemblies 7 are provided on both sides of the main frame 1. The side formwork assemblies 7 can be engaged with the ground to shape the concrete. The side formwork assemblies 7 are composed of multiple separate side plates 71 and are fixed to the ground in an orderly manner as the main frame 1 advances. Before the concrete loses its fluidity, the side plates 71 left on the ground can prevent the concrete from flowing outward. The main frame 1 can increase the forward speed without having to wait until the concrete loses its fluidity before advancing as in the prior art, thereby improving construction efficiency.

[0030] In this embodiment, the adjacent side panels 71 are penetrated by the pin 72, so that all the side panels 71 are connected into a long strip. The side panels 71 can rotate because of the pin 72, and then can be wound on the disk 73. At the same time, the side panels 71 are of a concave-convex design, with one side convex and the other concave. The convex and concave parts of the adjacent side panels 71 can match. When the side panels 71 are pulled apart from the disk 73 and fixed to the ground, the adjacent side panels 71 can be seamlessly connected to each other to ensure that the concrete will not leak. The disk 73 is fixed to the main frame 1 and moves with the main frame 1. The disk 73 is rotatably fixed to the main frame 1. During construction, the first side panel 71 or the first few are manually placed on the ground. The subsequent side panels 71 can be automatically pulled out from the disk 73 as the main frame 1 moves forward and thus fixed to the ground. During a construction cycle, that is, before a road is completely paved, if the side panels 71 are insufficient, the empty disc 73 can be removed and replaced with a new disc 73. The first side panel 71 on the new disc 73 is connected to the last side panel 71 of the previous side panel 71 by using the pin 72 to form a whole, and construction can continue.

[0031] In this embodiment, the side formwork assembly 7 further includes a guide assembly, which is composed of at least one guide roller 74 . The side plate 71 pulled out from the disk 73 can be guided to rest against the side of the concrete by the traction of the guide roller 74 .

[0032] In this embodiment, the side formwork assembly 7 also includes a plurality of ground nails 75, which are placed in a nail barrel 76 and are taken out from the nail barrel 76 one by one through a groove wheel 77. The taken out ground nails 75 fall vertically to the ground along the groove on the groove wheel 77. A hydraulic cylinder 78 is provided on the main frame 1. The output end of the hydraulic cylinder 78 can move downward along the groove on the groove wheel 77 to press the ground nails 75 into the ground, and the ground nails 75 are pressed against the back of the side panel 71 to prevent it from falling.

[0033] In this embodiment, the groove wheel 77 is installed at a corner of the nail barrel 76, and the axis of the groove wheel 77 is perpendicular to the horizontal plane. A motor 79 is provided on the top of the nail barrel 76 to drive the groove wheel 77 to rotate. The groove wheel 77 partially penetrates into the nail barrel 76. There are two grooves on the groove wheel 77, which can continuously bring the ground nails 75 in the nail barrel 76 out of the nail barrel 76. After the ground nails 75 are brought out of the nail barrel 76, they can fall to the ground along the groove. A circle of hoop 710 is provided on the part of the groove wheel 77 located outside the nail barrel 76. The hoop 710 is fixed on the nail barrel 76. The purpose of the hoop 710 is to prevent the ground nails 75 from falling off from the side of the groove.

[0034] In this embodiment, an arc-shaped push rod 711 is provided inside the nail barrel 76, and both ends of the push rod 711 extend out of the nail barrel 76. A guide sleeve 712 is fixed on the two walls outside the nail barrel 76 adjacent to the groove wheel 77. A guide rod 713 is movably fixed in the guide sleeve 712. The two guide rods 713 are respectively connected to the ends of the push rod 711 extending out of the nail barrel 76. A spring 714 is provided between the push rod 711 and the guide sleeve 712. The spring 714 is sleeved on the guide rod 713. Under the thrust of the spring 714, the push rod 711 moves linearly toward the groove wheel 77, thereby pushing the ground nail 75 in the nail barrel 76 toward the groove wheel 77, so that the ground nail 75 can be stuck on the groove wheel 77.

[0035] In this embodiment, the spiral distribution assembly 3 includes a spiral shaft 31 that can be raised and lowered and rotated. The spiral shaft 31 has spiral grooves with opposite rotation directions. The concrete falling from the funnel 2 can move to both sides through the spiral grooves on the spiral shaft 31, thereby making the distribution more uniform.

[0036] In this embodiment, the vibrating assembly 4 includes a plurality of elevating vibrating rods 41 , which can vibrate and compact the concrete to improve its strength and ensure the quality of the concrete.

[0037] In this embodiment, the rotary trowel assembly 5 includes a plurality of liftable rotary trowels 51 , which can smooth the concrete surface.

[0038] In this embodiment, the roller smoothing assembly 6 includes a plurality of pressing rollers 61, which can improve the smoothness of the concrete.

[0039] In this embodiment, the roller smoothing assembly includes a plurality of pressure rollers, which can improve the smoothness of the concrete.

[0040] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible.
