Description

Technical Field

[0001] This invention relates to the field of paver material feeding and conveying technology, and in particular to a main material feeding trolley for slope paver construction. Background Technology

[0002] In the field of water conservancy and hydropower engineering, the construction quality of asphalt paving panels for reservoirs of hydropower stations has a decisive impact on the seepage prevention performance of the dam. During the construction of the foundation pit slope structure, mechanized paving operations are typically carried out using a traction trolley to assist in pulling the paver. In slope paving operations, the asphalt concrete paver needs to reciprocate along the slope. Due to limitations in the equipment's hopper capacity, it needs to frequently travel back and forth to the top of the slope to replenish materials. Currently, the main feeding trolley used in slope paving is not convenient for quickly switching between conveying concrete and asphalt concrete when feeding materials to the paver, resulting in low material conveying and switching efficiency. After conveying concrete, the traditional hopper requires cumbersome washing and drying processes before it can be used for conveying asphalt concrete, affecting construction efficiency. Furthermore, the traditional feeding method uses a direct dumping mode, which makes the asphalt concrete prone to segregation under the impact of gravity, leading to a decrease in the uniformity of the paved layer and consequently affecting the quality of the engineering structure. Summary of the Invention

This avoids the cumbersome cleaning, drying, and oiling processes required after concrete delivery, which directly impact paving efficiency, as is the traditional method using only a hopper. The inner liner can be quickly removed for replacement, making it highly efficient and convenient. Furthermore, the discharge sleeve assists in guiding the concrete discharge, preventing segregation caused by excessive impact from a high discharge position. This ensures the quality of subsequent concrete paving. The adjustable inner liner also ensures smooth discharge of concrete through the discharge sleeve, preventing it from becoming entangled in the discharged concrete and hindering proper discharge.

[0015] In addition, by using a cut-off control device in conjunction with an infrared distance switch, the system detects when the paver moves to the paver platform and then controls the release of the two limit plates, preventing concrete or asphalt concrete from being discharged directly before the paver is in position. This avoids pollution and reduces cleaning time. It also avoids the inaccuracy of relying on manual observation of the paver's position, which is prone to misoperation. Attached Figure Description

[0023] In this embodiment, the feeding device 4 includes: a feeding hopper 401, positioning holes 4011, sliders 402, and discharge electric push rods 403. Two positioning holes 4011 are provided at the bottom of the feeding hopper 401. Sliders 402 are fixedly installed on both sides of the feeding hopper 401, and the two sliders 402 are slidably installed on the inclined track frame 1012.

The two stop plates 601 are respectively attached to the bottom of the feeding hopper 401. Two electric stop rods 602 are fixedly installed at the bottom of the feeding hopper 401, and the output shafts of the two electric stop rods 602 are respectively fixedly installed on the two stop plates 601. The quick-release guide 5 is used in conjunction with the feeding device 4 to ensure normal and stable feeding while facilitating quick switching between conveying concrete or asphalt concrete. This avoids the traditional method of conveying only by the feeding hopper 401, which requires tedious cleaning, drying, and oiling work after conveying concrete, directly affecting paving efficiency. This structure allows for quick removal of the inner liner 5. Replacement is efficient and convenient using the 03 model. The discharge sleeve 504 assists in guiding the concrete discharge process, preventing segregation due to the high impact force during direct placement and ensuring the quality of subsequent concrete paving. The liftable inner sleeve 503 ensures smooth concrete discharge through the discharge sleeve 504, preventing it from being obstructed by the discharged concrete. As concrete is discharged, the control discharge electric push rod 403 drives the quick-release frame 501 upwards, moving the inner sleeve 503 and discharge sleeve 504 upwards to ensure normal concrete discharge. When switching to asphalt concrete delivery, the inner sleeve 503 can be directly removed and replaced with a new quick-release guide component 5.

[0024] In Embodiment 2, based on Embodiment 1, the cutoff control component 6 further includes: a positioning shaft 603 and an electromagnet 604. The positioning shaft 603 is slidably inserted into each of the two cutoff plates 601, and an electromagnet 604 is fixedly mounted on each of the two positioning shafts 603. The two positioning shafts 603 are aligned with the two positioning holes 4011. The electromagnet 604 is electrically connected to the infrared distance switch 1011. The cutoff control component 6 also includes: a cutoff spring 605, which is sleeved on the positioning shaft 603 and connected between the positioning shaft 603 and the cutoff plate 601. 6. In conjunction with the infrared distance switch 1011, after the paver moves onto the paver platform 201, the two limit stop plates 601 are released to prevent concrete or asphalt concrete from being discharged directly before the paver is in position. This avoids pollution and reduces cleaning time. It also avoids the inaccuracy of relying on manual observation of the paver's position, which is prone to misoperation. Before the paver moves onto the paver platform 201, under the detection of the infrared distance switch 1011, the electromagnet 604 can be controlled to electromagnetically attract the positioning hole 4011. After the positioning shaft 603 is inserted into the positioning hole 4011, it plays a locking protection role.

[0025] The working principle of this embodiment is as follows: First, the end of the first steel cable 203 is connected to the concrete paver or asphalt concrete paver via a wire rope clip. The first winch 2021 is driven by the first reduction motor 202 to rotate, winding up the first steel cable 203 and pulling the paver. When the paver needs to replenish materials, it can be pulled onto the paver platform 201 via the first steel cable 203. At this time, the second winch 302 is driven by the second reduction motor 301 to wind up the second steel cable 303, causing the feeding hopper 401 to move upwards and feed materials into the paver. The material conveying process is as follows: When the feeding hopper 401 rises above the paver, the electric stop lever 602 can be controlled to drive the two stop plates 601 to no longer clamp the discharge sleeve 504. At this time, the discharge sleeve 504 can discharge concrete, and the guidance of the discharge sleeve 504 can prevent concrete segregation. Simultaneously, as the discharge occurs, the electric discharge lever 403 is controlled to drive the quick-assembly frame 501 to move upward, which in turn moves the inner liner 503 and the discharge sleeve 504 upward, ensuring normal concrete discharge. When it is necessary to switch to conveying asphalt concrete, directly... Remove the inner liner 503 and replace it with a new quick-release guide 5. Apply oil to the inside of the new quick-release guide 5 beforehand to prevent sticking. Switching is simple and convenient. When asphalt concrete needs to be discharged, the two stop plates 601 are driven off by the electric stop rod 602 to release the discharge sleeve 504, allowing the asphalt concrete to be discharged. After the paver moves onto the paver platform 201, the infrared distance switch 1011 detects the paver's movement and de-energizes the electromagnet 604, at which point the electromagnet 604 no longer attracts magnetic attraction. Positioning hole 4011: Under the compression of stop spring 605, positioning shaft 603 is pulled out from positioning hole 4011, at which point stop plate 601 can be moved to release clamping discharge sleeve 504. Conversely, before the paver moves onto paver platform 201, under the detection of infrared distance switch 1011, electromagnet 604 is controlled to electromagnetically attract positioning hole 4011. After positioning shaft 603 is inserted into positioning hole 4011, it plays a locking and protection role, avoiding misoperation and the problem of insufficient accuracy due to reliance on manual observation.
