Description

Technical Field

[0001] This utility model relates to the field of container equipment technology, specifically a hydraulically tilting self-unloading container. Background Technology

[0002] Hydraulic self-unloading containers are a type of special logistics equipment that combines the traditional functions of container cargo transportation with a hydraulic self-unloading device. It uses a hydraulic system to drive the inside or bottom of the container to tilt to one side, so that the cargo can be automatically unloaded from the side door without relying on external lifting equipment (such as cranes or forklifts), which greatly improves unloading efficiency. It is especially suitable for the transportation and unloading of bulk, granular or blocky cargo (such as ore, grain, building materials, etc.).

[0003] Referring to the patent with publication number CN222330544U: a hydraulic side-tipping self-unloading container, when unloading, the side door automatically opens due to the tilt of the container body and the pushing of the cargo. The size of the opening is uncontrolled. When dumping granular cargo, if the tilt angle of the container body is too small, the side door opening will be small, and the dumping process will be blocked by the side door, resulting in a decrease in flow. At the same time, the side door will block the observer's view in this state, making it impossible to observe the situation inside the container from the outside, affecting the personnel's judgment of the unloading progress. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a hydraulically tilting self-unloading container that automatically fixes the side door in the open state.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A type of structure comprising a plurality of side doors arranged side-by-side on the side wall of a container, the key technology of which is that the side door structure includes:

[0007] A side door, the upper end of which is hinged to the side wall of the container, and a side door lock shaft is provided on the lower outer side of the side door;

[0008] The lifting mechanism, located above the side door, includes a base detachably mounted on the side wall of the container and a winch mounted on the base. A rope is retractable on the winch, and a hook is provided at one end of the rope. The hook is mounted on the side door lock shaft.

[0009] A top block is detachably mounted on the lower end of the base. The lower end of the top block is provided with a contact surface. The winch winds up the rope, thereby driving the side door to press against the contact surface to fix the side door in the open state.

[0010] As one embodiment of this utility model, the base includes two horizontal plates arranged vertically opposite each other and two vertical rods arranged horizontally opposite each other. The two ends of the vertical rods are respectively connected to the two horizontal plates, and through pin holes are opened on the two horizontal plates.

[0011] In one embodiment of this utility model, two mounting blocks are arranged opposite each other on the side wall of the container. The mounting blocks are vertical strips with through mounting holes. The two ends of the mounting blocks abut against the two horizontal plates respectively, and the side of the mounting blocks abuts against the longitudinal rod. The mounting holes correspond to the pin holes so as to fix the base to the two mounting blocks by inserting fixing pins.

[0012] In one embodiment of this utility model, the fixing pin passes through both horizontal plates, and a pin cap is provided at the upper end of the fixing pin, the pin cap abutting against the upper horizontal plate.

[0013] In one embodiment of this utility model, the pin cap is provided with an annular pin cap hook.

[0014] In one embodiment of this utility model, the lower horizontal plate is provided with a plurality of mounting holes, and the top block is provided with a through countersunk hole corresponding to the mounting holes. Bolt assemblies are inserted through the countersunk hole and the mounting holes to install the top block on the base.

[0015] In one embodiment of this utility model, an angle is provided between the contact surface and the side wall of the container.

[0016] The beneficial effects of adopting the above technical solution are as follows:

[0017] This invention utilizes the weight of the material and the side door itself to open the side door during container side-tipping unloading. Then, a lifting mechanism installed on the container side wall drives the contact surface between the side door and the top block to press tightly, thus fixing the side door in the open state. At this time, the side door will not sag due to its own weight after a portion of the material is unloaded, allowing the observer to constantly monitor the unloading status inside the container. Simultaneously, the opening degree of the side door in the fixed state does not change with the unloading flow rate, ensuring unloading efficiency. Attached Figure Description

[0031] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0032] like Figures 1 to 3 The hydraulically tilting self-unloading container shown includes a hydraulic cylinder 101 mounted on the vehicle body 100 and a container 200 mounted on the hydraulic cylinder 1011. See also Figure 1 Several side door structures are arranged side by side on the side wall of container 200. Each side door structure is equipped with a locking mechanism to lock the side door 201 and prevent it from opening during transportation. In this embodiment, the lifting mechanism only requires the addition of a mounting block structure to an existing container. The winch can be fixedly installed using a pin connection between the base and the mounting block.

[0033] See Figure 4The side door structure includes a side door 201 hinged to the side wall of container 200 via a hinge structure, a lifting mechanism 1 detachably installed on the side wall of container 200, and a top block 6 installed on the lifting mechanism 1. The side wall of container 200 is provided with a discharge port corresponding to the side door 201 for material unloading or handling.

[0034] See details Figure 4 The lifting mechanism 1 is located above the unloading port in the middle. It includes a base detachably mounted on the side wall of the container 200 and a winch mounted on the base. A rope 3 can be wound and released on the winch. One end of the rope 3 is equipped with a hook 4. The locking mechanism includes a horizontal side door locking shaft 202 rotatably mounted below the side door 201. The hook 4 can be directly locked onto the side door locking shaft 202 or wrapped around the side door locking shaft 202 and then engaged with itself. See also Figure 3 and Figure 4 In this embodiment, two lock shaft supports 203 are arranged opposite each other in the middle of the side door lock shaft 202. The lock shaft 203 is fixed on the side door 201 to support the rotation of the side door lock shaft 202. The space between the two lock shaft supports 203 can be used to pass through the hook 4, which plays a limiting role in the hook 4 and prevents the hook 4 from moving along the length direction of the side door lock shaft 202.

[0035] See Figure 5 and Figure 6 The winch slowly winds up rope 3 to rotate the lower part of the side door 201 upwards. When the upper part of the side door 201 rotates to abut against the lower end face of the top block 6, the side door 201 is fixed and limited. After unloading is completed, the winch slowly releases rope 3, causing the side door 201 to droop down under its own weight to close the unloading port, thus resetting.

[0036] In this embodiment, the lifting mechanism 1 can be removed during vehicle transportation by using the pin connection between the base and the mounting block, thus avoiding damage to the winch during vehicle transportation. Before unloading, the lifting mechanism 1 can be installed on the mounting block, and the hook 4 can be connected to the side door lock shaft 202 to enter the unloading state.

[0037] See details Figures 7 to 10 The base includes two horizontal plates 1-1 arranged vertically opposite each other and two vertical rods 1-2 arranged horizontally opposite each other. The two ends of the vertical rods 1-2 are respectively connected to the two horizontal plates 1-1, and the two horizontal plates 1-1 are provided with through pin holes 1-3.

[0038] Two mounting blocks 2 are arranged opposite each other on the side wall of the container 200. The mounting blocks 2 are vertical strips with through mounting holes 2-1. The two ends of the mounting blocks 2 abut against the two horizontal plates 1-1 to limit the vertical displacement of the base. The side of the mounting blocks 2 abuts against the longitudinal rod 1-2 to limit the lateral displacement of the base. The mounting holes 2-1 correspond to the pin holes 1-3, and fixing pins 5 are inserted to fix the base to the two mounting blocks 2. By inserting and removing the fixing pins 5, the base and mounting holes 2 can be quickly disassembled or fixedly connected after the vehicle is parked. With the detachable structure of the hook 4 and the side door lock shaft 202, the lifting mechanism 1 can be quickly installed or disassembled.

[0039] See Figure 7 The fixing pin 5 passes through both horizontal plates 1-1, and a pin cap 5-1 is provided at the upper end of the fixing pin 5. The pin cap 5-1 abuts against the upper horizontal plate 1-1 to prevent the fixing pin 5 from falling. A ring-shaped pin cap hook 5-2 is provided on the pin cap 5-1 to facilitate quick removal of the pin cap 5-1.

[0040] See Figures 9 to 10 The cross section of the horizontal plate 1-1 is C-shaped. A connecting plate 1-1-1 is welded to the C-shaped notch of the lower part of the horizontal plate 1-1. Multiple through mounting holes are opened on the connecting plate 1-1-1 and the horizontal plate 1-1. A through countersunk hole 6-2 is opened on the top block 6 corresponding to the mounting holes. Bolt assemblies are inserted through the countersunk hole 6-2 and the mounting holes to tighten the top block 6 onto the connecting plate 1-1-1.

[0041] See Figure 9 and Figure 10 The contact surface 6-1 is provided at an angle with the side wall of the container 200, and the position of the contact surface 6-1 corresponds to the position of the side door 201 after it has been rotated into place. By replacing the top block 6 with different angles, the side door 201 can be fixed at different angles, such as... Figure 5 and Figure 6 The contact surface used is at a 55-degree angle. After the side door 201 is opened and fixed, the angle between the side door 201 and the side wall of the container 200 is 55 degrees.

[0042] See Figures 7 to 10The winch in this embodiment includes a drive motor mounted on a base, a transmission box mounted on the base, a rotating support mounted on the base, and a take-up and release shaft. The output shaft of the drive motor is connected to the input shaft of the transmission box, one end of the take-up and release shaft is connected to the output shaft of the transmission box, and the other end of the take-up and release shaft is rotatably mounted on the rotating support. In this embodiment, the winch is a TIANXI German-style winch, model TX-A-JK200-400, equipped with a wireless remote control module. It draws power from the vehicle's power module and is controlled by a wireless remote control.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
