Abstract
Description
Technical Field
[0001] This application relates to a transport vehicle, and more particularly to an easy-to-operate side-tipping unloading trolley. Background Technology
[0002] A handcart is a transport vehicle that is pushed and pulled by human power. Handcarts come in one-wheeled, two-wheeled, three-wheeled, and four-wheeled versions. Although material handling technology has continuously developed, handcarts remain an indispensable transport tool to this day. Handcarts are widely used in production and daily life because they are inexpensive, easy to maintain, convenient to operate, and lightweight. They can work in places where motor vehicles are inconvenient to use and are very convenient for moving lighter items over short distances.
[0003] Most existing trolleys use the front of the bucket as a fulcrum when unloading. The bucket is tilted from back to front during unloading. Since the bucket is relatively long in the front-to-back direction, it needs to be tilted at a large angle in order to smoothly discharge the material. This causes the center of gravity of the trolley to shift upwards by a large distance, which makes the trolley prone to tipping over and injuring users.
[0004] Therefore, in the prior art, some trolleys are designed with a side-tipping structure. The main advantage of this structure compared to the aforementioned scheme is that the left and right length of the trolley is shorter than the front and back length, so the change in the height of the center of gravity is less when it tipes over. As a result, the trolley is relatively more stable and the probability of the trolley tipping over is reduced.
[0005] However, tipping carts often present the problem of not being able to completely empty the material. If only one person is working, the cart can only be returned to its original position, and then the remaining material can be gradually shoveled out with tools. This is not only inefficient, but also leaves residual material in the cart, making it difficult to remove the material completely. In order to completely remove the material from the cart, two people are needed to work together: one person keeps the cart tipped over while the other person uses tools to shovel and scrape out the remaining material.
[0006] Therefore, it is necessary to design an easy-to-operate side-tipping unloading trolley that allows a single person to easily remove residual materials from the hopper. Summary of the Invention
[0007] The purpose of this application is to provide an easy-to-operate side-tipping unloading trolley with controllable tilt angle of the hopper for easy removal of residual materials.
[0008] This application is implemented as follows: an easy-to-operate side-tilting unloading trolley includes a chassis consisting of handrails and a base plate spaced between the two handrails. Suspension frames are symmetrically arranged on both sides of the rear of the chassis, and traveling wheels are installed at the bottom of the two suspension frames. A trolley bucket that can be tilted to one side is installed on the chassis. A follower rod is provided on at least one end face of the front and rear ends of the trolley bucket. An adjustment device for adjusting the tilting angle of the trolley bucket is fixed on the handrail on the side of the follower rod. The adjustment device includes a limiting plate fixedly connected to the handrail. A first sliding groove is opened on the limiting plate. The follower rod moves in the first sliding groove as the trolley bucket rotates. A first limiting plate that can rotate left and right is provided at the limiting plate. The leftward travel of the follower rod in the first sliding groove is blocked and limited by the first limiting plate.
[0009] The upper side of the limiting plate of the adjusting device has an arc-shaped first slide groove, and the lower side of the first slide groove has a concentrically arranged arc-shaped second slide groove. The lower part of the first limiting plate has a first insertion hole corresponding to the second slide groove. The first positioning rod is a rod with external threads. The first positioning rod passes through the first insertion hole and the second slide groove. One end is screwed with a locking nut, and the other end is fixed with a chuck. The chuck contacts the front side of the limiting plate.
[0010] A second limiting plate that can be adjusted to rotate left and right is provided at the limiting plate. The rightward travel of the follower rod in the first slide groove is blocked and limited by the second limiting plate.
[0011] The first and second limiting plates have the same structure and are coaxially arranged. The axis is located at the concentric point of the first and second sliding grooves. The first and second limiting plates are respectively provided on their opposite ends, and the positions of the first and second locking grooves correspond to the first sliding groove.
[0012] The handrail is located at the concentric point of the first slide groove and the second slide groove. The first limiting plate and the second limiting plate rotate around the handrail as an axis. The first bushing and the second bushing are fixedly connected to the lower ends of the first limiting plate and the second limiting plate, respectively, and the first bushing and the second bushing are in contact with the handrail.
[0013] The lower part of the second limiting plate has a second insertion hole corresponding to the second slide groove. The second positioning rod is a rod with external threads. The second positioning rod passes through the second insertion hole and the second slide groove. One end of the second positioning rod is screwed with a locking nut, and the other end is fixed with a clamp. The clamp contacts the front side of the limiting plate.
[0014] The first and second limiting plates can be located on the same side or both sides of the limiting plate and are coaxially arranged.
[0015] Symmetrical first limiting plates are provided on both sides of the limiting plate. The upper ends of the two first limiting plates are higher than the limiting plate and connected to form a first U-shaped plate. A second limiting plate is provided on the outer or inner side of each first limiting plate. The upper ends of the two second limiting plates are higher than the limiting plate and connected to form a second U-shaped plate.
[0016] A rotatable sleeve is fitted onto the handrail between the two bottom plates. The outer surface of the sleeve is fixedly connected to one side of the bottom of the truck bed. Limiting tubes are fixed on the handrails on both sides of the sleeve.
[0017] By implementing the above technical solution, this application limits the maximum tilting angle of the truck bed through an adjustment device and positions the tilted truck bed using a second limiting plate, allowing one person to complete the loading and unloading operations. During unloading, the tilting angle of the truck bed can be adjusted as needed, and the truck bed can be prevented from tilting backwards, improving operational safety. Attached Figure Description

The appearance of the above words in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0034] Example: Figure 1-7 As shown, the easy-to-operate side-tilting unloading trolley includes a chassis 5 consisting of handles 7 and base plates spaced apart between the handles 7. Suspension frames 8 are symmetrically arranged on both sides of the rear of the chassis 5. The bottom of the two suspension frames 8 is equipped with wheels 10. A trolley 2 that can be tilted to one side is installed on one of the handles 7. At least one end face of the front and rear ends of the trolley 2 is provided with a follower rod 1. An adjustment device for adjusting the tilting angle of the trolley is fixed on the handle 7 on the side of the follower rod 1. The adjustment device includes a limiting plate 11 fixedly connected to the handle 7. A first sliding groove 20 is opened on the limiting plate 11. The follower rod 1 moves in the first sliding groove 20 as the trolley 2 rotates. A first limiting plate 12 that can rotate left and right is provided at the limiting plate 11. The leftward travel of the follower rod 1 in the first sliding groove 20 is blocked and limited by the first limiting plate 12.
[0035] Furthermore, such as Figure 4 , 5 As shown in Figures 6 and 7, the upper side of the limiting plate 11 of the adjusting device has an arc-shaped first sliding groove 20, and the lower side of the first sliding groove 20 has a concentrically arranged arc-shaped second sliding groove 19. The lower part of the first limiting plate 12 has a first insertion hole 18 corresponding to the second sliding groove 19. The first positioning rod is a rod with external threads, which passes through the first insertion hole 18 and the second sliding groove 19. One end is screwed with a locking nut, and the other end is fixed with a chuck. The chuck contacts the front side of the limiting plate 11. When the locking nut is loosened, the locking nut gradually disengages from the first limiting plate 12, thereby reducing the frictional resistance on the first limiting plate 12. This allows the first limiting plate 12 to be rotated and adjusted so that it covers a certain part of the first sliding groove 20, thereby blocking the follower rod 1. After adjustment, tighten the locking nut so that the locking nut and the clamping head form a tension state on the first positioning rod, thereby increasing the friction between the locking nut and the first limiting plate 12, and between the clamping head and the limiting disc 11, thus completing the positioning of the first limiting plate 12.
[0036] Furthermore, the first limiting plate 12 is used to limit the leftward travel of the follower rod 1. In order to prevent the truck bed 2 from accidentally overturning during the unloading process, a second limiting plate 6 is required to limit the rightward movement of the follower rod 1 after the truck bed 2 has been overturned into place. The second limiting plate 6, which can be adjusted by left and right rotation, is provided at the limiting plate 11. The rightward travel of the follower rod 1 in the first slide groove 20 is blocked and limited by the second limiting plate 6.
[0037] The first limiting plate 12 and the second limiting plate 6 have the same structure and are coaxially arranged. This axis is located at the concentric point of the first sliding groove 20 and the second sliding groove 19. The first limiting plate 12 and the second limiting plate 6 have a first locking groove 15 and a second locking groove 16 respectively on their opposite ends. The positions of the first locking groove 15 and the second locking groove 16 correspond to the first sliding groove 20. The two sides of the follower rod 1 can enter the first locking groove 15 and the second locking groove 16 respectively, so that the first limiting plate 12 and the second limiting plate 6 form a stable left and right clamping structure for the follower rod 1.
[0038] In the embodiments of this application, the handrail 7 is located at the concentric point of the first slide groove 20 and the second slide groove 19, and the first limiting plate 12 and the second limiting plate 6 rotate about the handrail 7. The first bushing 21 and the second bushing 22 are respectively fixedly connected to the lower ends of the first limiting plate 12 and the second limiting plate 6, and the first bushing 21 and the second bushing 22 are sleeved with the handrail 7.
[0039] The lower part of the second limiting plate 6 has a second insertion hole 17 corresponding to the second sliding groove 19. The second positioning rod 23 is a rod with external threads, which passes through the second insertion hole 17 and the second sliding groove 19. One end of the second positioning rod 23 is screwed with a locking nut, and the other end is fixed with a clamp. The clamp contacts the front side of the limiting plate 11. When the locking nut is loosened, the locking nut gradually disengages from the second limiting plate 6, thereby reducing the frictional resistance on the second limiting plate 6. This allows the second limiting plate 6 to be rotated and adjusted so that it covers a certain part of the first sliding groove 20, thus preventing the follower rod 1 from moving in the opposite direction. After adjustment, the locking nut is tightened so that the locking nut and the clamp form a tension on the second positioning rod 23, thereby increasing the friction between the locking nut and the second limiting plate 6, and between the clamp and the limiting plate 11, thus completing the positioning of the second limiting plate 6.
[0040] The positional relationship between the first limiting plate 12, the second limiting plate 6, and the limiting plate 11 can be as follows:
[0041] like Figure 5 As shown, the first limiting plate 12 and the second limiting plate 6 can be located on the same side of the limiting plate 11 and are coaxially arranged;
[0042] like Figure 6As shown, the first limiting plate 12 and the second limiting plate 6 can be located on both sides of the limiting plate 11 and are coaxially arranged.
[0043] like Figure 7 As shown, to enhance the stability of the limiting position, symmetrical first limiting plates 12 are provided on both sides of the limiting plate 11. The upper ends of the two first limiting plates 12 are higher than the limiting plate 11 and connected to form a first U-shaped plate. A second limiting plate 6 is provided on the outside of each first limiting plate 12. The upper ends of the two second limiting plates 6 are higher than the limiting plate 11 and connected to form a second U-shaped plate.
[0044] like Figure 3 As shown, a rotatable sleeve 13 is fitted onto the handrail 7 between the two bottom plates. The outer surface of the sleeve 13 is fixedly connected to one side of the bottom of the truck bed 2. Limiting tubes (not shown in the figure) are fixed on the handrail 7 on both sides of the sleeve 13. The limiting tubes are fitted onto the handrail 7.
[0045] like Figure 1 , 2 As shown in Figure 3, bearings 9 are installed at the lower ends of the two suspension frames 8, and axles 4 are installed between the two bearings 9. Wheels 10 are installed at both ends of the axles 4. Front supports 14 are symmetrically arranged on both sides of the front bottom surface of the chassis 5. The front supports 14 and the wheels 10 provide front and rear support for the chassis 5, allowing the chassis to stand relatively stably on the ground.
[0046] To facilitate the upward lifting and flipping of the truck bed 2, a handle 3 is provided on the outer wall of the truck bed 2.
[0047] In use, the first limiting plate 12 is first adjusted and positioned, that is, the maximum tilting angle of the truck bed 2 during unloading is adjusted. After the goods are transported to the designated position, the handle 3 is lifted upwards to tilt the truck bed 2 towards the unloading side. The follower rod 1 moves along the first sliding groove 20 as the truck bed 2 tilts until one side of the follower rod 1 enters the first slot 15 and stops moving. At this point, the truck bed 2 reaches its maximum tilting angle. Then, the second limiting plate 6 is rotated towards the follower rod 1 until the second slot 16 contacts the follower rod 1. The locking nut on the second positioning rod 23 is tightened to position the second limiting plate 6, thereby limiting the left and right travel of the follower rod 1. This achieves the positioning of the tilting of the truck bed 2, ensuring that the truck bed 2 maintains a certain tilting angle during unloading to facilitate unloading.
[0048] After unloading is completed, loosening the locking nut on the second positioning rod 23 releases the positioning of the second positioning rod 23, allowing the follower rod 1 to move in the opposite direction, thereby allowing the truck bed 2 to reverse and reset. The first limit plate 12 generally does not need to rotate and can maintain its positioning state after the initial adjustment.
[0049] This application limits the maximum tilting angle of the truck bed 2 using an adjustment device and positions the tilted truck bed 2 using a second limiting plate 6, allowing one person to complete the loading and unloading operations. During unloading, the tilting angle of the truck bed 2 can be adjusted as needed, and the reverse tilting of the truck bed 2 can be prevented, improving operational safety.
[0050] The above technical features constitute the embodiments of this application, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the needs of different situations.
