Description

Technical Field

[0001] This utility model relates to the field of self-unloading truck technology, and in particular to a quick-unloading truck body. Background Technology

[0002] When loading or unloading goods in a truck bed, the truck bed must wait together for the loading or unloading of goods, which takes a lot of time, and the truck driver has to wait. In order to speed up the loading and unloading of goods, modern truck beds usually have a tilting function to facilitate quick and convenient loading and unloading of goods.

[0003] For example, Chinese patent application CN 202322637295.0 discloses a liftable and unloadable replacement truck body composed of a truck body with an openable central door on its side. Telescopic lifting devices are symmetrically arranged on both sides of the truck body near the central door, and concealed lifting devices are located on the rear edges of both sides of the truck body. The telescopic and concealed lifting devices raise or lower the truck body, effectively avoiding the waiting time for truck drivers to load and unload goods. After replacing the truck body, transportation can begin immediately, resulting in extremely high transportation efficiency. However, by suspending the truck body in mid-air, the self-weight requirement of the truck body is relatively high, and the effective volume of the truck body is greatly limited. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a quick-release carriage to solve the technical problem that the existing technology, which uses the method of raising and suspending the carriage body, has high requirements for the carriage's own weight and greatly limits the effective volume of the carriage.

[0005] To achieve the above objectives, this utility model provides a quick-release truck body, comprising a truck body and a pressure-bearing base disposed on the lower side of the truck body, a tilting frame hinged to the pressure-bearing base, the truck body being disposed within the tilting frame, and the quick-release truck body further comprising:

[0006] The top support plate, there are several top support plates, and all of the top support plates are hinged to the tilting frame. The top of the top support plate is engaged with the bottom of the carriage body through an elastic positioning member.

[0007] A support roller, which is installed between two adjacent top support plates;

[0008] Drive component one for driving the tilting frame to tilt;

[0009] Drive component two for driving several of the top support plates to perform a flipping action.

[0010] Furthermore, the elastic positioning element includes:

[0011] A connector, which is slidably and limit-mounted on the top of the top support plate;

[0012] A spring is disposed within the top support plate and abuts against the connector. The connector is connected to the lower end of the carriage body via the spring.

[0013] Furthermore, the driving component one includes:

[0014] Hydraulic cylinder one, which is movably mounted on the middle part of the pressure-bearing base via a mounting seat;

[0015] A hinge joint is installed at the lower end of the tilting frame and is rotatably mounted on the output end of the hydraulic cylinder.

[0016] Furthermore, the second driving component includes:

[0017] Hydraulic cylinder two is installed at the lower end of the tilting frame, and the tilting frame has an clearance opening;

[0018] A transmission rod is mounted on the output end of the second hydraulic cylinder;

[0019] A connecting rod, the lower end of which passes through the clearance opening and is hinged to the transmission rod, and the upper end of which is hinged to the side end of the top support plate.

[0020] Furthermore, when the output end of the second hydraulic cylinder is extended, the top support plate flips downward, and the height of the top outer edge of the support roller is higher than that of the top support plate.

[0021] Furthermore, when the output end of the second hydraulic cylinder is in the retracted state, the top support plate flips upward, and the height of the top support plate is higher than the top outer edge of the support roller.

[0022] Furthermore, a limiting angle iron is installed on one side of the tilting frame, and the side end of the limiting angle iron is in contact with the body of the carriage.

[0023] Furthermore, a movable buckle plate is installed on the other side of the tilting frame, and the side end of the movable buckle plate is attached to the other side of the carriage body.

[0024] The beneficial effects of this utility model are as follows: When using the quick-release carriage of this utility model, the first drive component drives the tilting frame to tilt, and the second drive component drives the top support plate to tilt synchronously. In the tilted state of the pressure base, the carriage body is quickly detached by the support rollers in close contact with the carriage body. The self-weight requirement of the carriage body is relatively low, and the effective volume of the carriage body is not limited, making it more adaptable. Attached Figure Description

[0035] The first aspect of this utility model proposes a quick-release carriage, such as... Figure 1-5 As shown, the system includes a carriage body 1 and a pressure-bearing base 2 located on the underside of the carriage body 1. A tilting frame 3 is hinged to the pressure-bearing base 2, and the carriage body 1 is located inside the tilting frame 3. The quick-release carriage also includes:

[0036] There are several top support plates 4, and all of them are hinged to the tilting frame 3. The top of the top support plate 4 is engaged with the bottom of the car body 1 through an elastic positioning member.

[0037] Support roller 5, which is installed between two adjacent top support plates 4;

[0038] Drive component 1 for driving the tilting frame 3 to tilt;

[0039] Drive component two is used to drive several top support plates 4 to perform a flipping action.

[0040] In this embodiment, the elastic positioning element includes:

[0041] Connector 6, the connector 6 is slidably limited and installed on the top of the top support plate 4;

[0042] A spring is located inside the top support plate 4 and rests against the connector 6. The connector 6 is connected to the lower end of the carriage body 1 via the spring.

[0043] In this embodiment, the driving component one includes:

[0044] Hydraulic cylinder 7 is movably mounted on the middle part of the pressure-bearing base 2 via mounting seat 8;

[0045] Hinged joint 9 is installed at the lower end of the tilting frame 3 and is rotatably mounted on the output end of hydraulic cylinder 7.

[0046] In this embodiment, the driving component two includes:

[0047] Hydraulic cylinder 2 10 is installed at the lower end of the tilting frame 3, and the tilting frame 3 is provided with an clearance opening 11;

[0048] Transmission rod 12 is mounted on the output end of hydraulic cylinder 2 10;

[0049] The lower end of the connecting rod 13 passes through the clearance opening 11 and is hinged to the transmission rod 12, while the upper end of the connecting rod 13 is hinged to the side end of the top support plate 4.

[0050] Working process and principle: In this embodiment, during the unloading process, the first drive component drives the tilting frame 3 to tilt, and the second drive component drives the top support plate 4 to tilt synchronously. In the tilted state of the pressure base 2, the support roller 5 and the carriage body 1 are in contact, so that the carriage body 1 can be quickly unloaded.

[0051] Specifically, the process is as follows: First, open the movable buckle plate 15 on one side of the tilting frame 3, then start the hydraulic cylinder 2 10 so that its output end drives the transmission rod 12 to slide in the clearance opening 11 on the tilting frame 3. During the sliding process, the corresponding top support plate 4 is driven to rotate synchronously through each connecting rod 13, thereby separating the plug 6 on the top support plate 4 from the bottom of the car body 1, and the bottom of the car body 1 directly contacts the support roller 5. Then, start the hydraulic cylinder 1 7 so that its output end extends and pushes the tilting frame 3 through the hinge joint 9, causing it to rotate around the hinge point with the pressure base 2. This allows the car body 1 to be quickly and automatically unloaded, which has a lower self-weight requirement for the car body 1 and the effective volume of the car body 1 is not limited, making it more adaptable.

[0052] In this embodiment, when the output end of the hydraulic cylinder 2 10 is extended, the top support plate 4 flips downward, and the height of the top outer edge of the support roller 5 is higher than that of the top support plate 4.

[0053] In this embodiment, when the output end of the hydraulic cylinder 2 10 is in the retracted state, the top support plate 4 flips upward, and the height of the top support plate 4 is higher than the top outer edge of the support roller 5.

[0054] In this embodiment, a limiting angle iron 14 is installed on one side of the tilting frame 3, and the side end of the limiting angle iron 14 is in contact with the carriage body 1.

[0055] In this embodiment, a movable buckle plate 15 is installed on the other side of the tilting frame 3, and the side end of the movable buckle plate 15 is attached to the other side of the carriage body 1.
