Description

Technical Field

[0001] This utility model belongs to the technical field of road engineering maintenance equipment, and relates to a material loading device for maintenance vehicles. Background Technology

[0002] In the maintenance of infrastructure such as roads and bridges, maintenance vehicles play a crucial role. They can perform a series of operations such as road repair and maintenance to ensure smooth and safe traffic. The loading device of the maintenance vehicle, as an important component of the maintenance vehicle, is responsible for transporting repair materials into the maintenance vehicle for processing. Its work efficiency and stability directly affect the overall progress of the maintenance operation.

[0003] Currently, the mainstream working method of the feeding device used in existing maintenance vehicles is to lift the hopper to a certain height through a corresponding lifting mechanism, and then control the hopper to flip, thereby pouring the material loaded inside into the maintenance vehicle for subsequent processing.

[0004] However, in actual use, these existing feeding devices have many defects, affecting the efficiency and effectiveness of maintenance operations. On the one hand, the materials used in maintenance operations, such as asphalt mixtures and cement slurry, often have a certain degree of viscosity. When the hopper is guiding the material, the material is very easy to stick to the inner wall of the hopper. With the increase of the number of uses, more and more material will stick, which will affect the loading capacity of the hopper and the subsequent feeding accuracy. More seriously, in some cases, the material cannot be completely poured out of the hopper, which requires manual cleaning, which increases labor costs and delays the progress of maintenance operations.

[0005] On the other hand, during outdoor maintenance operations, due to the complex and diverse working environment, maintenance vehicles are sometimes limited by factors such as terrain and space, and cannot directly drive to the material accumulation area. In this case, the ideal solution is to separate the hopper from the elevator so that the hopper can be manually or with the help of other small equipment to be transported to the material accumulation area for loading. Then, the hopper filled with material can be installed back onto the elevator for feeding. However, in existing feeding devices, the hopper and elevator are usually fixedly connected or integrated, and cannot be separated. This makes it difficult to carry out feeding work smoothly when the maintenance vehicle cannot get close to the material accumulation area, which seriously affects the efficiency of maintenance operations and cannot meet the needs of operations under complex working conditions. Utility Model Content

[0006] The technical problem this utility model aims to solve is that in some cases, materials cannot be completely poured out of the hopper, requiring manual cleaning, which increases labor costs and delays the progress of maintenance work. The hopper and the elevator are usually fixedly connected or integrated, making separation impossible. This makes it difficult to carry out the feeding work smoothly when the maintenance vehicle cannot approach the material accumulation area, seriously affecting the efficiency of maintenance work.

[0007] The present invention discloses a material loading device for a maintenance vehicle, comprising a maintenance vehicle body and a lifting machine body. The lifting machine body is mounted on the maintenance vehicle body, and a hopper is provided on the side of the lifting machine body away from the maintenance vehicle body. A connecting mechanism is provided between the hopper and the lifting machine body, which is used for separating and installing the lifting machine body and the hopper. A pushing mechanism is provided inside the hopper, which is used to assist in unloading materials. Evenly distributed heightening support legs are fixedly connected to the bottom of the hopper.

[0008] Preferably, the connecting mechanism includes a fixing plate, and the fixing plate is fixedly connected to the side of the lifting machine body away from the maintenance vehicle body. The fixing plate is L-shaped, and a hanging ring is sleeved on the side wall of the fixing plate. A U-shaped plate is fixedly connected to the side of the hanging ring away from the fixing plate. A pull rod is provided on the inner side of the U-shaped plate, and the two ends of the pull rod pass through the U-shaped plate and the hanging ring respectively and are movably connected to the U-shaped plate and the hanging ring.

[0009] Preferably, the pushing mechanism includes a lifting plate, which is slidably connected to the inner side of the hopper. An internal threaded ring is symmetrically fixedly connected to the top of the lifting plate. A screw is threadedly connected to the inner side of the internal threaded ring. An ear plate is rotatably connected to the top of the screw. The side of the ear plate away from the screw is fixedly connected to the inner side of the hopper. The bottom end of the screw passes through the hopper and is movably connected to the hopper.

[0010] Preferably, the connecting mechanism further includes a positioning groove, on the side of the fixed plate opposite to the U-shaped plate, the positioning groove is provided, the end of the pull rod opposite to the hanging ring extends into the positioning groove, a circular plate is fixedly connected to the end of the pull rod near the hanging ring, a spring is sleeved on the end of the pull rod, and the two ends of the spring are fixedly connected to the circular plate and the U-shaped plate respectively.

[0011] Preferably, the feeding mechanism further includes a synchronous pulley, a synchronous pulley is fixedly connected to the bottom end of the screw, a synchronous belt is installed between the two synchronous pulleys, a drive motor is installed on one side of the hopper near the bottom, a grooved pulley is fixedly connected to the output end of the drive motor and the bottom of the adjacent synchronous pulley, and a transmission belt is installed between the two grooved pulleys.

[0012] Furthermore, the end of the pull rod opposite the fixed plate is inclined, and the end of the pull rod away from the hanging ring is fixedly connected to a pull ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model, through the cooperation between the hopper, hanging ring, U-shaped plate, pull rod, spring and pull ring, can realize the separation and installation between the elevator body and the hopper, and can lock them after installation. It can effectively solve the problem that the feeding work is difficult to carry out smoothly when the maintenance vehicle cannot approach the material accumulation area.

[0015] This invention utilizes the cooperation between a hopper, a lifting plate, a screw, a synchronous wheel, a drive motor, and a grooved wheel to enable the drive motor to raise or lower the lifting plate via two screws, thereby pushing the material out of the hopper. This effectively solves the problem of materials not being completely discharged from the hopper, requiring manual cleaning and increasing labor costs. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1

[0029] like Figures 1 to 8 As shown, the device includes a maintenance vehicle body 21 and a hoist body 1. The hoist body 1 is mounted on the maintenance vehicle body 21. A hopper 2 is provided on the side of the hoist body 1 away from the maintenance vehicle body 21. A connecting mechanism is provided between the hopper 2 and the hoist body 1. The connecting mechanism is used for separating and installing the hoist body 1 and the hopper 2. A pushing mechanism is provided inside the hopper 2. The pushing mechanism is used to assist in pouring materials. The bottom of the hopper 2 is fixedly connected with evenly distributed heightening support legs 20.

[0030] like Figures 6-8 As shown, the connecting mechanism includes a fixed plate 7. The fixed plate 7 is fixedly connected to the side of the hoist body 1 away from the maintenance vehicle body 21. The fixed plate 7 is L-shaped. A hanging ring 3 is sleeved on the side wall of the fixed plate 7. A U-shaped plate 4 is fixedly connected to the side of the hanging ring 3 away from the fixed plate 7. A pull rod 5 is provided inside the U-shaped plate 4. The two ends of the pull rod 5 pass through the U-shaped plate 4 and the hanging ring 3 respectively and are movably connected to the U-shaped plate 4 and the hanging ring 3. The connecting mechanism also includes a positioning groove 8. A positioning groove 8 is opened on the side of the fixed plate 7 opposite to the U-shaped plate 4. The end of the pull rod 5 opposite to the hanging ring 3 extends into the positioning groove 8. A circular plate 9 is fixedly connected to the end of the pull rod 5 near the hanging ring 3. A spring 6 is sleeved on the end of the pull rod 5. The two ends of the spring 6 are fixedly connected to the circular plate 9 and the U-shaped plate 4 respectively. The end of the pull rod 5 opposite to the fixed plate 7 is inclined. A pull ring 10 is fixedly connected to the end of the pull rod 5 away from the hanging ring 3.

[0031] The top of the fixing plate 7 has a chamfer, which makes it easier for the top of the fixing plate 7 to slide into the hanging ring 3 when connected. The connecting mechanism allows the elevator body 1 and the bucket 2 to be installed and disassembled. When disassembling, the pull rod 5 needs to be pulled to separate from the positioning groove 8, and the fixing plate 7 will fall and the hanging ring 3 will disengage as the elevator body 1 continues to descend. This eliminates the need for workers to manually lift the bucket 2 to disassemble, effectively improving the convenience of use.

[0032] Example 2

[0033] like Figures 2-5 As shown, the feeding mechanism includes a lifting plate 11, which is slidably connected to the inner side of the hopper 2. An internal threaded ring 12 is symmetrically fixedly connected to the top of the lifting plate 11. A screw 13 is threadedly connected to the inner side of the internal threaded ring 12. An ear plate 14 is rotatably connected to the top of the screw 13. The side of the ear plate 14 away from the screw 13 is fixedly connected to the inner side of the hopper 2. The bottom end of the screw 13 passes through the hopper 2 and is movably connected to the hopper 2. The feeding mechanism also includes a synchronous wheel 15. A synchronous wheel 15 is fixedly connected to the bottom end of the screw 13. A synchronous belt 16 is installed between the two synchronous wheels 15. A drive motor 17 is installed on one side of the hopper 2 near the bottom. A grooved wheel 18 is fixedly connected to the output end of the drive motor 17 and the bottom of the adjacent synchronous wheel 15. A transmission belt 19 is installed between the two grooved wheels 18.

[0034] The material pushing mechanism can push the material in the hopper 2 outward when needed. In addition, the gap between the lifting plate 11 and the inner wall of the hopper 2 is small, so when the lifting plate 11 moves upward, it can also scrape the inner wall of the hopper 2 to avoid excessive material adhering to the inner wall of the hopper 2. The two screws 13 rotate in the same direction, so the internal thread ring 12 needs to match the screw 13 to avoid the lifting plate 11 tilting. In addition, the lifting plate 11 and the inner wall of the hopper 2 are provided with sliders and grooves to further stabilize the stability of the lifting movement of the lifting plate 11.

[0035] Working Principle: In use, the elevator body 1 is first installed on the maintenance vehicle body 21. When loading materials, the hopper 2 can be separated from the elevator body 1. To achieve this separation, the elevator body 1 controls the hopper 2 to descend. During descent, the pull ring 10 pulls the pull rod 5, compressing the spring 6 and causing the pull rod 5 to disengage from the positioning groove 8. After the elevator body 1 lowers the hopper 2 and it contacts the ground, the elevator body 1 continues to descend, causing the fixing plate 7 on the elevator body 1 to disengage from the hanging ring 3. This achieves separation of the hopper 2 from the elevator body. The purpose of separation is to move hopper 2 to the place where it is needed. After filling hopper 2 with material, hopper 2 is moved back to its original position. Then, by controlling the elevator body 1, the fixed plate 7 is raised, so that the fixed plate 7 is inserted from the bottom of the hanging ring 3. When the elevator body 1 drives hopper 2 to rise, the pull ring 10 is released. At the same time, the rebound force of the spring 6 pushes the circular plate 9 and the pull rod 5 to move towards the fixed plate 7, so that the pull rod 5 enters the positioning groove 8. In this way, the hanging ring 3 can be fixed on the fixed plate 7, so that hopper 2 will not detach from the elevator body 1 and fall into the maintenance vehicle body 21 when the material is loaded and turned.

[0036] The hopper 2 is lifted above the maintenance vehicle body 21 by the elevator body 1 and then tilted to pour the material into the maintenance vehicle body 21. When the material is difficult to pour out, the drive motor 17 can be started to rotate forward by controlling the power supply. The drive motor 17 drives the synchronous pulley 15 and the screw 13 to rotate through the grooved pulley 18 and the transmission belt 19. Through the cooperation of the screw 13 and the internal threaded ring 12, the lifting plate 11 rises when the screw 13 rotates forward, so that the lifting plate 11 can push the material in the hopper 2 outward, which is convenient to use. After the material in the hopper 2 has been poured out, the drive motor 17 can be reversed by controlling the external power supply. The screw 13 can be reversed, causing the lifting plate 11 to descend. When the lifting plate 11 descends to its limit position, the drive motor 17 is turned off. Then, the hoist body 1 is controlled to drive the hopper 2 to descend to the initial position. The above operation can effectively solve the problem that in some cases, the material cannot be completely poured out of the hopper, requiring manual cleaning, which increases labor costs and delays the progress of maintenance work. The hopper and the hoist are usually fixedly connected or integrated, and cannot be separated. This makes it difficult to carry out the feeding work smoothly when the maintenance vehicle cannot get close to the material accumulation area, which seriously affects the efficiency of maintenance work.

[0037] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
