Description

Technical Field

[0001] This utility model belongs to the technical field of road construction machinery and equipment, specifically relating to a lateral material transfer device for a paver. Background Technology

[0002] A paver is a construction equipment mainly used for paving base and surface asphalt materials in highways, roads, bridges, parking lots and other places. Its core function is to evenly lay and compact asphalt and other paving materials to form a smooth and flat road surface structure. During operation, the paver holds the material in the hopper, distributes it laterally through the diffusion spiral, and then compacts it by the traction screed, finally providing a road surface that meets the design requirements. However, during the paving construction process, the paver needs to stop frequently to wait for the transport vehicle to pour the bulk material into the paver hopper. The paver pushes the transport vehicle forward, affecting the paving efficiency. At the same time, frequent stops can easily lead to discontinuous paving and the possible appearance of joints. Traditional transfer devices have the following core problems: (1) Installation and disassembly are time-consuming and labor-intensive: using bolt fixing or welding, a single disassembly and assembly takes 2 hours, which seriously affects the construction efficiency; (2) Insufficient lateral transfer capacity: only supports lateral conveying at a fixed height, which cannot adapt to the multi-angle material placement needs of widening road sections, which can easily lead to material accumulation or shortage.

[0003] Therefore, with the development of mechanization and intelligence in road construction, there is an urgent need for a material transfer device that is quick to install and disassemble, highly compatible, and low-loss, in order to solve the pain points of traditional equipment in terms of disassembly and assembly efficiency, working condition adaptability, and material conveying accuracy, and to meet the higher requirements of modern engineering for construction efficiency and quality.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] See Figure 1-5A paver lateral material transfer device includes a scraper extension section 1 of the paver scraper, a conveyor frame 2 located directly below the scraper extension section 1, a transition frame fixedly connected to one end of the conveyor frame 2, and a folding frame 3 hinged to the end of the transition frame away from the conveyor frame 2. The folding frame 3 can rotate and fold towards the conveyor frame 2. An active roller 4 is provided between the ends of the conveyor frame 2, and driven rollers 5 are respectively provided between the middle of the transition frame and the ends of the folding frame 3. Multiple conveyor belt roller groups 6 are spaced along the length of the conveyor frame 2 and the folding frame 3, wherein the roller group 6 is a V-shaped roller group structure in the prior art. A support frame 7 and a mounting frame 8 are spaced apart at the upper end of the conveyor frame 2. A drive mechanism 9 that can drive the active roller 4 to rotate is provided on the support frame 7. A rotating mechanism 10 that allows the conveyor frame 2 to rotate is provided on the side of the mounting frame 8 near the transition frame. A traction mechanism 11 that allows the folding frame 3 to be raised and lowered is provided at the upper end of the mounting frame 8.

[0022] The preferred rotating mechanism 10 includes a guide positioning post 1001, a loose sleeve 1002, a C-frame 1003, and a hydraulic telescopic cylinder 1004. Two mounting ears 12 are fixedly provided at height intervals on the side of the paver near the scraper extension section 1, with the mounting ears 12 welded to the side of the paver near the scraper extension section 1. The guide positioning post 1001 is vertically positioned between the two mounting ears 12, each with a through hole. The guide positioning post 1001 is positioned on the mounting ear 12 between the two through holes, and a pin is fixedly connected to the upper end of the guide positioning post 1001 to prevent it from falling downwards. This design facilitates the detachment of the guide positioning post 12. Loose sleeves 1002 are respectively fitted on the upper and lower sides of the guide positioning post 1001, wherein the loose sleeves 1002 can be rotated on the guide positioning post 1004. The C-frame 1003 rotates on its side, with both ends of the C-frame 1003 fixedly connected to one side of the two loops 1002. The two loops 1002, on the side away from the C-frame 1003, are fixedly connected to the mounting frame 8 via connecting blocks. The connecting blocks are perpendicular to the C-frame 1003. Two bushings are spaced apart on the side of the C-frame 1003 away from the loops 1002, and a shaft is rotatably connected between the two bushings. The hydraulic telescopic cylinder 1004 is rotatably mounted on one side of the paver. The output end of the hydraulic telescopic cylinder 1004 is movably connected to the shaft. During construction, the hydraulic telescopic cylinder 1004 is activated, which pushes the C-frame 1003, thereby allowing the conveyor frame 2 to move along the guide positioning column 1001 in the direction of the scraper extension section 1 until the middle of the conveyor frame 2 is directly below the scraper extension section 1.

[0023] The preferred mounting frame 8 has a positioning component on the side away from the rotating mechanism 10. The positioning component includes a positioning insert plate 13 and a positioning pin 14. The positioning pin 14 consists of three vertically spaced pins and a flat plate welded to the top of the three pins. A U-shaped fixing groove 15 is fixed on the paver directly above the scraper extension section 1. The positioning insert plate 13 is fixed on one side of the mounting frame 8 and can be inserted into the U-shaped fixing groove 15. The U-shaped fixing groove 15 and the positioning insert plate 13 are respectively provided with one through hole opposite to the other. The positioning insert plate 13 and the U-shaped fixing groove 15 are fixed by the positioning pin 14. In use, when the positioning insert plate 13 moves into the U-shaped fixing groove 15, the positioning pin 14 is inserted into the through hole, which can further ensure the stability of the entire device when conveying materials.

[0024] The preferred mounting frame 8 is equipped with positioning components on both the upper and lower sides, and two U-shaped fixing grooves 15 are fixed on the paver directly above the scraper extension section 1, which can further ensure the stability of the device.

[0025] The preferred traction mechanism 11 includes a hydraulic rotary cylinder 1101, a traction shaft 1102, and a traction rope 1103. The traction shaft 1102 is horizontally rotatably mounted on the top of the mounting frame 8. The hydraulic rotary cylinder 1101 is fixed on the top of the mounting frame 8, and its output end is connected to one end of the traction shaft 1102. The two sides of the folding frame 3 are respectively connected to the traction ropes 1103, and the ends of the two traction ropes 1103 are respectively twisted onto the traction shaft 1102. In use, the hydraulic rotary cylinder 1101 is started, which drives the traction shaft 1102 to rotate, so that the traction ropes 1103 can be wound up and down to adjust the lifting and lowering of the folding frame 3, thus meeting the requirements of multi-angle material conveying.

[0026] The preferred folding frame 3 has two traction ropes 1103 spaced apart on both sides, and the ends of the four traction ropes 1103 are twisted onto the traction shaft 1102, which can further stabilize the folding frame 3.

[0027] The preferred folding frame 3 is fixed with hooks on both sides. One end of a turnbuckle 1104 is connected to the hook and the other end is connected to the traction rope 1103. The turnbuckle 1104 can be adjusted to tighten the traction rope 1103 when necessary.

[0028] The preferred drive mechanism 9 includes a hydraulic motor 901, two sprockets, and an annular chain 902. The hydraulic motor 901 is fixed on the support frame 7. The two sprockets are respectively sleeved on the output end of the hydraulic motor 901 and the rotating shaft of the drive roller 4. The two sprockets are linked by the annular chain 902. When conveying materials, the hydraulic motor 901 is started and its rotation drives the annular chain 902 to rotate, which in turn drives the drive roller 4 to rotate, thereby driving the conveyor belt 16 to rotate and realize the conveying of materials.

[0029] The preferred hydraulic telescopic cylinder 1004, hydraulic rotary cylinder 1101 and hydraulic motor 901 are connected to the paver's hydraulic system to achieve power source from the paver's hydraulic system without the need for an additional power unit.

[0030] The preferred hydraulic telescopic cylinder 1004, hydraulic rotary cylinder 1101 and hydraulic motor 901 are connected to the controller via signal lines, and the controller is connected to the paver control system.

[0031] The working principle of this utility model is as follows: When construction requires lateral material conveying, the hydraulic telescopic cylinder 1004 is activated, which pushes the C-shaped frame 1003, thereby allowing the conveying frame 2 to move along the guide positioning column 1001 along the scraper extension section 1 until the middle of the conveying frame 2 is directly below the scraper extension section 1. Further, when the two positioning plates 13 move into the U-shaped fixing groove 15 respectively, the positioning pin 14 is inserted into the through hole to fix the positioning plates 13. Then, the height of the folding frame 3 is adjusted to meet the material conveying angle. During adjustment, the hydraulic rotating cylinder 1101 is activated, which drives the traction shaft 1102 to rotate, thereby realizing the release and retraction of the traction rope 1103 to adjust the lifting and lowering of the folding frame 3. When the paver is moving to a new location or when construction is completed, first control the start of the hydraulic rotary cylinder 1101 to rotate and pull the traction rope 1103 to retract, which in turn pulls the folding frame 3 to rotate toward the conveyor frame 2 to complete the folding and unfolding. Then, pull out the two positioning pins 14 to make the two positioning plates 13 movable. Next, control the start of the hydraulic telescopic cylinder 1004 to pull the C-shaped frame 1003, which in turn moves the conveyor frame 2 away from one end of the scraper extension section 1 and makes one end of the folding frame 3 close to the other side of the paver to complete the unfolding and unfolding.

[0032] This device, through its quick-assembly and disassembly-free design, multi-angle conveying, and high compatibility, solves the problems of cumbersome disassembly and assembly, inflexible material placement, and poor versatility of traditional transfer equipment, achieving a comprehensive improvement in construction efficiency, material placement accuracy, and equipment utilization. Furthermore, this device is suitable for various asphalt and cement-stabilized soil paving projects, as well as interlayer backfilling for New Jersey guardrails, and is particularly advantageous in projects with tight schedules and complex conditions, possessing broad market promotion value and promising industry application prospects.
