Description

Technical Field

[0001] The utility model relates to a container structure with a self-unloading function, and in particular to a rear-turning container with a fixed bottom frame and a rear-turning box bucket. Background Art

[0002] As an internationally common cargo loading tool, containers have been widely used in railways, highways, and shipping, and are an internationally common modular transportation method. Existing containers are 20 feet, 30 feet, 40 feet, and 45 feet long; there are high-top and low-top containers; there are open-top and self-unloading containers.

[0003] At present, the transportation volume and mileage of coal and powder and granular goods are very large. Most of the coal in the existing market is transported by ordinary sluice semi-trailers, 8.6-meter rear dump trucks, and 9.6-meter ordinary vehicles, and only a small part is transported by rail. There are also some dump semi-trailers that have serious illegal private modification and transportation, which have serious spillage, unsafe, and difficult unloading problems. In recent years, the call for "bulk to container" in the industry has become increasingly louder. At the same time, along with the transformation of "bulk to container", a series of problems need to be solved, such as spillage, effective / complete self-unloading, unloading safety, and unloading requirements in different directions. Utility Model Content

[0004] In view of the above existing problems, the utility model provides a rear-flip container with a fixed chassis and a rear-flip bucket. The structure of this container is an open-top self-unloading container, and an automatic or manual tarpaulin system can be optionally installed on the top to solve the problems of loading and spilling. At the same time, the solution of the utility model is to install an electric hydraulic system on the container to achieve self-unloading of goods without moving the container body frame, thereby solving the problems of difficult and unsafe unloading. The rear-flip container with a fixed chassis and an inner flip bucket provided by the utility model effectively solves the defects and problems existing in the existing transportation and loading and unloading of powdered and granular goods such as coal, and expands the functions of the container. The container realizes the function of unloading the container to one side, and the design of each part of the structure is reasonable, simple, convenient, and the box body has better strength and stronger applicability.

[0005] Specifically, the utility model provides a rear-turnable container with a fixed chassis and a rear turn-around box, the container comprising a fixed chassis, a rear turn-around box and a lifting assembly of the rear turn-around box. The fixed chassis constitutes a bottom load-bearing frame of the container; the rear turn-around box is installed on the fixed chassis and can rotate (turn backward) around the rear of the fixed chassis; the lifting assembly is arranged at the front of the fixed chassis and provides power for the rotation of the rear turn-around box.

[0006] Furthermore, the container also includes a fixed front box plate at the front. The fixed front box plate and the fixed chassis form an integrated load-bearing frame structure, and the fixed front box plate and the rear flip box are used to accommodate the lifting assembly, and preferably form the appearance of a conventional container together with the rear flip box and the fixed chassis in the fallen state, thereby ensuring the beauty of the appearance of the entire container product, and being used to shield, protect and store internal components (such as lifting assemblies). In this regard, preferably, the fixed front box plate can have a concave cross-section, which is used to form a accommodating chamber for the lifting assembly (with the rear flip box); or, the surface of the rear flip box facing the fixed front box plate can be set to have a concave cross-section, and together with the fixed front box plate, it forms a accommodating chamber for the lifting assembly. For this reason, preferably, the fixed front box plate is also provided with a front box plate small door, which is used for, for example, maintenance, installation and commissioning of the lifting assembly. Commonly, the front box plate small door can be set as a small double-opening door on the front side.

[0007] At the same time, in order to form the above-mentioned accommodating chamber for the lifting assembly, the front part (upper part or top part) of the box body of the rear flip box has a shield plate extending forward and capable of connecting or overlapping with the fixed front box plate. The shield plate is located on the upper part of the lifting assembly and is used to shield the lifting assembly to form a hidden accommodating chamber whose contents cannot be seen from the outside (when in the falling back state). At the same time, for example, in view of the need to set a tarpaulin mechanism in conjunction with the container, the shield plate is preferably set on the upper front part of the rear flip box, so that the space between the rear flip box and the fixed front box plate is divided into a lower closed lifting assembly accommodating chamber and an upper open concave groove. At this time, the upper concave groove can be used to at least partially accommodate or assemble supporting facilities such as the tarpaulin mechanism. Furthermore, in order to prevent the rear flip box from shaking left and right relative to the load-bearing frame in the falling back state, a matching limit device is set at the junction of the shield plate and the fixed front box plate.

[0008] Preferably, at least the top end of the fixed front box board and the top of the rear side of the rear flip box (i.e., for example, the four top corners of the container) are provided with container corner fittings for lifting, so as to realize the lifting of the whole container. The shield of the rear flip box has a setting for giving way to container corner fittings at the junction with the top of the fixed front box board, so as to facilitate lifting.

[0009] Furthermore, the rear flip box has a small door and a locking mechanism; the small door is arranged on the rear side of the rear flip box (rotatably connected to the upper edge) for opening from the lower edge to unload when needed; the locking mechanism is used to lock the small door. In addition, a power door opening device can also be provided for the small door.

[0010] Furthermore, after falling, the rear flip box falls on the load beam of the fixed chassis, so that the cargo load surface of the rear flip box is attached to the crossbeam load surface of the fixed chassis. Furthermore, a limiter (such as a wedge-shaped limiter block, etc.) is provided between the bottom surface of the rear flip box and the fixed chassis, and cooperates with the beam on the chassis or the bottom surface of the box to limit the relative movement between the two when the rear flip box falls on the fixed chassis, such as front-to-back, left-to-right shaking or displacement.

[0011] Furthermore, the lifting assembly includes a hydraulic cylinder and a matching cylinder seat; two ends of the cylinder seat are rotatably connected to the front side (surface) of the rear dump box and the front part of the fixed chassis.

[0012] Further, optionally, the lifting assembly also includes a hydraulic power unit arranged at the front of the fixed chassis. Of course, it is also possible to select a tractor or a hydraulic station utilizing the front to provide power for the hydraulic cylinder.

[0013] Furthermore, the rear dump box and the fixed chassis can be rotated by a flip pin shaft arranged at the rear of the fixed chassis.

[0014] The utility model is a rear-flip container with a fixed bottom frame and a rear-flip bucket, which has the following advantages: First, the bottom of the container is made into a complete bottom-bearing frame structure with a fixed bottom frame and a fixed front box plate. Preferably, the fixed front box plate of the container body, the (lifting component) cylinder seat, the hydraulic cylinder, and the hydraulic power unit form a complete load-bearing frame structure that are integrated into a complete large frame structure, which plays the role of bearing the bottom of the container and ensuring the strength of the box body. In terms of the rear-flip and self-unloading function, the rear-flip bucket is composed of a rear-flip bucket, a small door of the rear-flip bucket, and a locking mechanism. After being lifted by the lifting component on the front side, it can reach a lifting state of 40-50 degrees to one side, so that the entire container frame can be kept stationary and all the goods can flow down to the rear and be self-unloaded. The fixed chassis is also provided with a cylinder seat, a hydraulic cylinder, a hydraulic power unit, and a flip pin. The bottom beam of the rear flip box is directly mounted on the load-bearing beam of the fixed chassis, so that the cargo-bearing surface of the rear flip box is attached to the crossbeam of the fixed chassis, which greatly improves the overall structural strength of the container. In addition, a limiting means is provided between the rear flip box and the integrated load-bearing structure to ensure the overall stability of the container product under normal non-lifting use conditions. At the same time, the setting of the fixed front box plate enables the upper container corner pieces provided on the top of the container to be connected to the fixed chassis, so that the whole container can be lifted. The utility model can be applied to containers of various lengths and heights; according to different usage scenarios, the utility model can also choose to use the front tractor or hydraulic station to take power to lift the rear flip box (at this time, the power unit is optional).

[0015] In application, when transporting ordinary goods, the container of the utility model can also be loaded and unloaded from the small door of the rear flip box, and can also be loaded and unloaded from the top; the top can also be equipped with an automatic or manual tarpaulin system to effectively prevent rain or prevent goods from spilling, achieving an environmentally friendly effect. The utility model provides a rear flip container with a fixed bottom frame and a rear flip box, which has a simple structure, high safety, and easy processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is a further description of the utility model of "a rear-turnable container with a fixed base frame and a rear-turnable box body" in conjunction with the accompanying drawings.

[0024] See also Figure 1-6 The utility model provides a rear-turnable container with a fixed base frame and a rear-turnable box, which is composed of a fixed base frame 1, a fixed front box plate 2, a cylinder seat 3, a hydraulic cylinder 4, a rear-turnable box 5, a rear-turnable box door 6, a turning pin 7, a locking mechanism 8, and a hydraulic power unit 9 (optional).

[0025] by Figure 2The present invention is described in the direction shown in the figure. The present invention forms a complete bottom load-bearing frame structure by making the bottom of the container into a fixed chassis 1. A rear flip box 5 is installed on the fixed chassis 1, which can rotate based on multiple flip pins 7 on the right side. The rear flip box 5 is provided with a rear flip box door 6 (rotatably connected) and a matching locking mechanism 8 installed on the fixed chassis 1 on the rear (right side). A shield is provided on the upper front part of the box body of the rear flip box 5, which forms a hidden lifting component accommodating chamber with the fixed front box board 2 when the box body falls. This example does not involve the cooperation with the additional tarpaulin mechanism, so the shield is set to be basically flush with the top surface of the container to provide a larger lifting component accommodating chamber. In the case of considering the installation of accessories such as the tarpaulin mechanism, the present invention can design the position of the shield to be the upper front part (or the middle and upper part) of the rear flip box 5, and the shield can also be designed to be a folding plate or a curved shape that cooperates with the fixed front box board 2 (that is, the upper concave groove is a trapezoidal cross-section or an arc cross-section, etc., which is matched as needed). At the same time, the above-mentioned shielding plates can be designed to have matching limiting means with the fixed front box plate 2, such as wedge-shaped limiting pieces and matching grooves, to prevent relative displacement.

[0026] Similarly, means such as wedge-shaped limit blocks (not shown) are also provided between the bottom surface of the rear dump box 5 and the fixed base frame 1 to prevent the box from shaking and shifting.

[0027] The fixed front box board 2 and the fixed base frame 1 form an integral load-bearing frame structure. In addition to the front panel, the fixed front box board 2 also has vertical panels on both sides, forming a concave cross-section, thereby forming a receiving chamber together with the front side of the rear dump box 5 and the shield plate to accommodate the lifting components. At the same time, in order to debug and overhaul the lifting components, the front side of the fixed front box board 2 has a front box board small door that opens in opposite directions. Furthermore, the top of the vertical columns on both sides of the fixed front box board 2 is also provided with upper container corner pieces for overall lifting.

[0028] The fixed base frame 1 is also provided with a cylinder seat 3, a hydraulic cylinder 4 and a hydraulic power unit 9 of a lifting assembly on the left side, and a flip pin 7 on the right side.

[0029] The rearward tipping process of the container is as follows: when the rear tipping bucket 5 needs to be lifted and unloaded, the locking mechanism 8 of the rear tipping bucket 5 is unlocked, the rear tipping bucket small door 6 is in a state that can be opened, and the hydraulic power unit 9 starts to work, driving the hydraulic cylinder 4 to lift, and the rear part of the rear tipping bucket 5 connected to the other end of the hydraulic cylinder 4 rotates along the flip pin 7 at the rear of the fixed chassis 1, the front part of the rear tipping bucket 5 rises, the lower edge of the rear tipping bucket small door 6 opens, and the goods are unloaded from the rear of the rear tipping bucket 5. After the rear tipping bucket 5 is unloaded, the hydraulic power unit 9 is operated to rotate the rear part of the rear tipping bucket 5 along the flip pin 7 at the rear of the fixed chassis 1, and the front part of the rear tipping bucket 5 descends. After the rear tipping bucket 5 is lifted, it is in a state of 40-50 degrees to the rear, so that all the goods can flow down from the rear and unload themselves, so that the entire container frame can be unloaded to one side without moving the entire container frame. When the rear tipping bucket 5 descends to the fixed chassis 1, the locking mechanism 8 will lock the rear tipping bucket small door 6. At this time, the rear dump box 5 is completely placed on the load-bearing beam of the bottom frame 5 .

[0030] Preferably, the upper container corner pieces arranged at the four top corners of the container are all connected to the fixed base frame 1, so that the whole container can be lifted.

[0031] In order to increase the strength of the container and make unloading convenient and reasonable, the utility model adopts a structure of a fixed chassis 1 (sub-frame) plus a rear flip box 5, a fixed front box plate 2, a cylinder seat 3, a hydraulic cylinder 4, a hydraulic power unit 9, and a flip pin 7 to form a complete load-bearing frame structure that is connected as a whole to form a complete large frame structure, which plays a role in the bottom load and box strength of the container; ordinary goods can also be loaded and unloaded from the rear flip box small door 6, and can also be loaded and unloaded from the top. The utility model rear flip box small door 6 is equipped with a locking mechanism 8 locking device of the rear flip box small door that is opened in linkage with the subsequent lifting of the flip box 5, making unloading safer. Therefore, the structural container is simple to operate, safe, practical and reliable.
