Specific embodiments
[0030] The following will further elaborate on the present utility model in conjunction with the accompanying drawings and specific embodiments.
[0031] As Figure 1-6 shown, a fiber - oriented STC ultra - high toughness concrete vibrating paver includes a front support mechanism and a rear support mechanism arranged front and rear along the traveling direction of the paver; a feeding component and a vibration component are arranged on the front support mechanism, and a leveling component is arranged on the rear support mechanism; the front support mechanism is connected to the rear support mechanism; the feeding component includes a feeding hopper and a blanking plate, the feeding hopper has a feeding port and a discharging port, an inclined blanking plate is fixedly connected to the discharging port of the feeding hopper, and a plurality of baffles are arranged on the upper surface of the blanking plate; the vibration component includes a vibration generator extending along the left - right direction and a fixed bracket for fixing the vibration generator to the bottom of the blanking plate, the vibration generator spans across the bottom of the blanking plate and abuts against the bottom of the blanking plate; the paver further includes a plurality of vibrating pipes, and the vibrating pipes are arranged behind the front support mechanism.
[0032] As Figure 4-5 shown, the vibration generator includes a cylindrical shell and a camshaft arranged inside the cylindrical shell, and a plurality of axially - arranged inward - protruding protrusions are evenly distributed on the inner wall of the cylindrical shell; the vibration component further includes an external motor, the output end of the external motor is connected to the camshaft, and when the camshaft rotates, the camshaft strikes the protrusions to generate vibration.
[0033] Specifically, the protrusions of the camshaft are made of a relatively soft plastic material, and the distance from the highest point of the protrusion of the camshaft to the axis is slightly greater than the distance from the highest point of the protrusion of the cylindrical shell to the axis; the shell of the vibration generator abuts against the bottom of the blanking plate. When the external motor is started, the motor drives the camshaft to rotate, and the protruding part of the camshaft strikes the protrusions on the inner wall of the cylindrical shell, thereby generating vibration. The vibration wave is transmitted to the blanking plate through the cylindrical shell and the fixed bracket. The vibration wave can improve the fluidity of the concrete, make the concrete flow more smoothly during blanking on the blanking plate, improve the blanking efficiency, and at the same time can also play a role in pre - vibration, reducing the subsequent vibration time.
[0034] In addition, different types of concrete have different fluidities. The power of the external motor can be adjusted as needed to regulate the frequency and intensity of the vibration waves, enabling the paver to be equally applicable to the paving operations of different types of concrete and improving the scope of application.
[0035] In this embodiment, the fixed bracket includes two side plates fixed before and after the cylindrical vibration generator and a bottom plate fixed at the bottom of the cylindrical vibration generator. The two side plates are fixed to the bottom of the feeding tray by bolts, the bottom plate is fixedly connected to the side plates, and 4 diagonal braces for supporting and fixing the cylindrical shell are also provided on the bottom plate.
[0036] As Figure 1-3 shown, the front support mechanism includes a square frame structure provided at the bottom. The square frame structure includes multiple longitudinal beams arranged along the traveling direction of the paver and multiple cross beams; columns for supporting the hopper are provided above the square frame structure; the cross beam at the rearmost end of the square frame structure supports the end outlet of the feeding tray; two tires are respectively detachably installed on the left and right sides of the square frame structure.
[0037] Two extended cantilevers extending rearward are also provided at the rear end of the square frame structure. The rear support mechanism includes two square steel pipes arranged in parallel along the traveling direction, and the two square steel pipes are respectively fixedly connected to the two extended cantilevers by bolts.
[0038] In this embodiment, styrene-butadiene rubber tires are used, greatly improving the passability of the concrete paver, enabling the concrete paver to be applicable to the operating environments of different terrains, and further expanding the scope of application of the paver.
[0039] The shape of the feeding tray is an isosceles trapezoid, and multiple baffles are provided on the upper surface. The baffles evenly divide the upper surface of the feeding tray into multiple concrete flow channels. Multiple vibrating pipes are arranged uniformly in the left-right direction on the cross beam at the rearmost end of the square frame structure, and the vibrating pipes are inclined from the front upper direction to the rear lower direction.
[0040] Specifically, the feeding tray is inclined from the front upper direction to the rear lower direction. The baffles divide the feeding tray into multiple concrete flow channels. The vibrating pipes are arranged on the cross beam below the outlet of the concrete flow channels, and the vibrating pipes are inclined from the front upper direction to the rear lower direction. When the concrete falls from the concrete flow channels, the vibrating pipes are inserted into the falling concrete at this time and vibrate it. In addition, multiple baffles are provided on the upper surface of the feeding tray, which not only enables the concrete to be evenly distributed during the falling process, but also enables the STC ultra-high toughness concrete added with fiber reinforcement materials to have the fiber reinforcement materials combed and oriented under the action of the baffles and vibration waves when passing through the concrete flow channels, so that most of the fiber reinforcement materials in the concrete after falling have relatively consistent directions, improving the paving quality.
[0041] The leveling assembly includes an auger shaft, a first leveling shaft, and a second leveling shaft that are successively arranged between two square steel pipes from front to back.
[0042] Specifically, the auger shaft of the leveling assembly can preliminarily distribute and level the falling concrete. The first leveling shaft rolls the preliminarily distributed and leveled concrete, and the second leveling shaft performs secondary rolling on the preliminarily rolled concrete, improving the paving quality of the paver.
[0043] As Figure 6 shown, the bottom of the hopper is inclined from the front upper direction to the rear lower direction, and the discharge port is arranged at the rear lower part of the bottom of the feeding port; a cover plate is also arranged on the top of the hopper.
[0044] Specifically, the bottom of the hopper is inclined, and the inclination angle relative to the horizontal plane is 6 degrees. The discharge port is arranged at the position where the hopper is connected to the feeding tray. The cover plate can prevent sundries from entering the hopper and improve the quality of the concrete.
[0045] The working process of the present utility model is as follows:
[0046] The prepared ultra-high toughness concrete is introduced into the hopper from the feeding port. The concrete flows out from the discharge port of the hopper under its own weight and flows into the feeding tray, and is evenly distributed by the baffle to the concrete flow channel. At this time, the external motor of the vibration assembly starts to drive the camshaft to start the vibration generator, and the vibration wave is transmitted to the feeding tray through the cylindrical shell and the fixed bracket. The vibration wave can improve the fluidity of the concrete, making the concrete flow more smoothly in the concrete flow channel. The baffle of the feeding tray combs the direction of the reinforcing fiber material, and at the same time, the feeding tray and the vibration assembly play a role in pre-vibrating the concrete. When the concrete flows down to the ground from the concrete flow channel, the vibrating pipe is inserted into the concrete at this time for vibrating operation to reduce the phenomenon of voids and unevenness, and then it is leveled three times through the auger shaft, the first leveling shaft, and the second leveling shaft of the leveling assembly, so as to obtain a flat concrete platform.
[0047] Generally speaking, the present utility model is provided with a feeding assembly and a vibration assembly on the front support mechanism, improves the fluidity of the concrete through the vibration wave, sets a vibrating pipe at the rear of the square frame structure, and sets a leveling assembly on the rear support mechanism, enabling the paver to realize three major functions of smooth sliding feeding, automatic vibration, and automatic leveling, and can also comb the direction of the reinforcing fiber material, thereby improving the construction efficiency and quality and reducing the labor cost; SBR rubber tires are arranged on both sides of the square frame structure, enabling the paver to have good passability and be applicable to different terrain working environments; The structure of the present utility model is simple, the materials are easy to obtain, and most of the components are connected by high-strength bolts, making the disassembly and assembly convenient, facilitating operation, and further reducing the cost.
[0048] The above embodiments are the preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present utility model shall be equivalent replacement methods and are all included in the protection scope of the present utility model.
