Description

Technical Field

[0001] This utility model relates to the field of curbstone unloading auxiliary technology, specifically a curbstone unloading auxiliary carriage. Background Technology

[0002] As an important component of road edges, curb stones are mainly used to separate sidewalks from roadways and protect the road edge structure. They are usually made of materials such as concrete and stone, with a single stone weighing 50-150kg and having a long strip structure (mostly 50-100cm in length). During road construction, curb stones need to be transported to the construction site by truck and then unloaded from the truck to the designated location, which is one of the key links in road construction.

[0003] When using existing technology, the curb stones are lifted off the transport vehicle by hoisting equipment, eliminating the need for manual handling, which is safe and labor-saving.

[0004] However, in actual use, due to the large size of the hoisting equipment and its inconvenience in moving it, it is only suitable for open spaces. It is difficult to carry out operations in narrow road construction areas (such as roads in old urban areas and roads inside residential areas), and the equipment rental cost is high. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an auxiliary carriage for unloading curb stones, which solves the problems that, in actual use, the lifting equipment is large in size, inconvenient to move, only suitable for open spaces, and difficult to operate in narrow road construction areas (such as old city roads and internal roads of residential areas), and the equipment rental cost is high.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a curbstone unloading auxiliary carriage, comprising a mounting shell, a roller installed inside the mounting shell, a baffle fixedly connected to the outer wall of the mounting shell, a hanging rod installed on one side of the baffle, the outer wall of the roller rotatably connected to the inner wall of the mounting shell via a bearing, a connecting rod fixedly connected to the inner wall of the roller, the outer wall of the connecting rod movably connected to the inner wall of the mounting shell, and a linkage device installed on the outer wall of the connecting rod.

[0007] Preferably, the linkage device includes a sprocket, the inner wall of which is fixedly connected to the outer wall of the connecting rod, and a chain is engaged with the outer wall of the sprocket.

[0008] Preferably, the outer wall of the chain is provided with a fixed shell, the outer wall of the fixed shell is fixedly connected to the outer wall of the baffle, a reducer is fixedly connected to the outer wall of the fixed shell, and the output end of the reducer is fixedly connected to one end of the connecting rod through a sealed bearing passing through one end of the fixed shell.

[0009] Preferably, the lower part of the outer wall of the hanging rod is provided with a thread, the outer wall of the thread is threadedly connected to a fixing block, the outer wall of the fixing block is rotatably connected to a connecting block through a pin, and the outer wall of the connecting block is fixedly connected to the outer wall of the baffle.

[0010] Preferably, a limiting block is fixedly connected to the end of the baffle away from the hanging rod, an auxiliary plate is rotatably connected to the side of the limiting block via a pin, a pin is fixedly connected to the bottom of the auxiliary plate, a fixing plate is fixedly connected to the end of the auxiliary plate that passes through the limiting block, and the outer wall of the fixing plate is fixedly connected to the outer wall of the limiting block by bolts.

[0011] Beneficial effects This utility model provides an auxiliary carriage for unloading curb stones. It offers the following advantages: The auxiliary carriage, through the cooperation of a hanging rod, mounting shell, and rollers, uses the hanging rod to mount the carriage on the side of the vehicle. The mounting shell and rollers allow the curb stone to slide down from above. Driven by a linkage device, each roller rotates at the same speed, ensuring stability during unloading. This solves the problems of large size, inconvenient movement, and suitability only for open areas, making it difficult to operate in narrow road construction areas (such as old city roads or internal roads of residential areas), as well as high equipment rental costs.

[0012] By combining the hanging rod, connecting block, and baffle, and utilizing the threads on the hanging rod, the length of the hanging rod on the connecting block can be adjusted. This allows the auxiliary mounting device to be installed on transport vehicles of different heights, thereby increasing the overall usability of the device and solving the problem of its large size and inconvenience in actual use.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In actual use, due to the large size of the hoisting equipment, it is inconvenient to move and can only be used in open areas. It is difficult to carry out operations in narrow road construction areas (such as roads in old urban areas and roads inside residential areas), and the equipment rental cost is high.

[0017] In view of this, the present invention provides an auxiliary carriage for unloading curb stones, which solves the problems that, in actual use, the lifting equipment is large in size, inconvenient to move, only suitable for open spaces, difficult to carry out operations in narrow road construction areas (such as old city roads and internal roads of residential areas), and has high equipment rental costs.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0019] Example 1: By Figure 1-4 It is known that a curbstone unloading auxiliary carriage includes a mounting shell 1, a roller 2 installed inside the mounting shell 1, a baffle 3 fixedly connected to the outer wall of the mounting shell 1, a hanging rod 7 installed on one side of the baffle 3, the outer wall of the roller 2 being rotatably connected to the inner wall of the mounting shell 1 through a bearing, a connecting rod 10 fixedly connected to the inner wall of the roller 2, the outer wall of the connecting rod 10 being movably connected to the inner wall of the mounting shell 1, and a linkage device installed on the outer wall of the connecting rod 10; In the specific implementation process, it is worth noting that the outer wall of the roller 2 is equipped with a rubber anti-slip sleeve with sufficiently deep treads to increase the friction between the roller 2 and the curb. When using the auxiliary slide, the hanging rod 7 is hung on the side of the vehicle to effectively support the auxiliary slide and make it more stable during operation. The baffle 3 can block the curb and prevent it from deviating and falling from both sides of the slide during the descent, thus avoiding danger to the workers. The connecting rod 10 and the linkage device connect all the rollers 2 on the auxiliary slide together, which makes it easy to control the rotation speed of the rollers 2 and effectively control the sliding speed of the curb. Moreover, the mounting shell 1 and the baffle 3 are made of high-strength steel structure so that they will not deform under the weight of the curb. Similarly, the hanging rod 7 should be made of a stronger alloy to support the entire device. Furthermore, the linkage device includes a sprocket 11, the inner wall of which is fixedly connected to the outer wall of the connecting rod 10, and a chain 12 is engaged with the outer wall of the sprocket 11. In the specific implementation process, it is worth noting that the teeth on the outer wall of the sprocket 11 can mesh with the gaps on the chain 12. In this way, under the meshing of the sprocket 11 and the chain 12, the rollers 2 used on the carriage rotate synchronously, which is convenient for controlling the descent speed of the curbstone. At the same time, it is worth noting that the shape of the sprocket 11 and the chain 12 is not shown in the figure. It depends on the actual situation. Moreover, only their installation position is shown in the figure. It is worth noting that in this case, multiple sprockets 11 are used for synchronous transmission via a chain 12 to ensure the "three similarities" of all sprockets 11: Same module and same pitch: The core parameters of sprocket 11 and chain 12 must be completely matched (e.g., if the pitch of chain 12 is 12.7mm, the pitch of all sprockets 11 must also be 12.7mm), otherwise it will cause chain 12 to jam and sprocket 11 to skip teeth. Same rotation plane: The tooth planes of all sprockets 11 must be strictly aligned (error ≤ 0.1mm / 100mm wheelbase), which can be calibrated by a laser alignment instrument to prevent chain 12 from failing prematurely due to "uneven wear"; Same steering requirements: Determine the rotation direction of sprocket 11 according to the transmission direction to ensure that the chain 12 is evenly stressed and has no additional lateral tension; In addition, it is necessary to precisely control the center distance and arrangement of the sprockets 11 to ensure that the tension of the chain 12 is appropriate. If necessary, a tensioning device can be added to optimize the installation accuracy of the sprockets 11, and regular maintenance and lubrication are required to ensure the synchronization of multiple sprockets 11 through the chain 12. Furthermore, a fixed shell 4 is provided on the outer wall of the chain 12. The outer wall of the fixed shell 4 is fixedly connected to the outer wall of the baffle 3. A reducer 5 is fixedly connected to the outer wall of the fixed shell 4. The output end of the reducer 5 is fixedly connected to one end of the connecting rod 10 through a sealed bearing penetrating one end of the fixed shell 4. In the specific implementation process, it is worth noting that the fixed shell 4 will enclose the sprocket 11 and chain 12, so that the two will not be affected by external interference and malfunction during operation. The reducer 5 is connected to one of the connecting rods 10. Under the drive of the sprocket 11 and chain 12, the rotation speed of all rollers 2 is controlled by the reducer 5, thereby controlling the sliding speed of the curbstone. The reducer 5 can be a shaft-end planetary sprocket reducer damper, with the outer wall fixed to the surface of the fixed shell 4 and the shaft end fixed to the end of one of the connecting rods 10. This prevents the speed from being too fast and causing the curbstone to slide too far due to inertia, which could endanger the workers. When the curbstone is placed on the carriage and slides down the carriage, it can be manually supervised and supported to ensure that the curbstone does not deviate or fall.

[0020] Example 2: From Figure 1-4 It can be seen that a thread 8 is provided on the lower part of the outer wall of the hanging rod 7, and a fixing block 9 is threadedly connected to the outer wall of the thread 8. A connecting block 13 is rotatably connected to the outer wall of the fixing block 9 through a pin, and the outer wall of the connecting block 13 is fixedly connected to the outer wall of the baffle 3. In the specific implementation process, it is worth noting that the groove of thread 8 is relatively deep. This can prevent the pressure difference between the hanging rod 7 and the fixing block 9 from causing damage to thread 8 and affecting its rotation. When installing the carriage, according to the height of the vehicle, the hanging rods 7 on both sides are rotated the same number of turns and hung on the vehicle's guardrail. The carriage body is tilted under the action of the connecting block 13 and the fixing block 9. In this way, the curb will slide according to the inclination of the carriage body. It is worth noting that when placing the carriage, the ground under the carriage must be flat to avoid instability when placing the carriage. Furthermore, a limiting block 14 is fixedly connected to the end of the baffle 3 away from the hanging rod 7. An auxiliary plate 6 is rotatably connected to the side of the limiting block 14 via a pin. A pin 16 is fixedly connected to the bottom of the auxiliary plate 6. A fixing plate 15 is fixedly connected to the end of the auxiliary plate 6 that passes through the limiting block 14. The outer wall of the fixing plate 15 is fixedly connected to the outer wall of the limiting block 14 via bolts. In the specific implementation process, it is worth noting that after the carriage is installed on the side of the vehicle, the auxiliary plate 6 at the bottom of the main body is pressed against the ground, and the pin 16 at the bottom is inserted into the ground. This can fix it. After it is placed, the fixing plate 15 is fixed to the limiting block 14 with bolts to fix the position of the auxiliary plate 6. The auxiliary plate 6 is made of high-density rubber. When the curb slides onto the auxiliary plate 6, the elasticity of the auxiliary plate 6 will protect it and reduce the force of the curb contacting the ground, thereby protecting it.
