Description

Technical Field

[0001] This utility model belongs to the field of transportation equipment technology, specifically a bulk container based on a front-end crane. Background Technology

[0002] Currently, containers are widely used in bulk cargo transportation to load bulk materials such as coal and ore. Containers are frequently used for loading and unloading bulk materials into train cars. Existing container unloading methods include top-discharge and side-discharge, which require tipping the container over during unloading, allowing the bulk material to spill from the top or side into the train car. During unloading inside the train car, the bulk material falls from a considerable distance, creating turbulence and causing a violent dispersion of fine particulate matter, resulting in significant air pollution and impacting the health of on-site workers. Therefore, it is necessary to design a device that can control the unloading of the container from the bottom using a bottom locking mechanism, thereby reducing dust generation during unloading. Utility Model Content

[0003] To address the above technical problems, this utility model provides a device that can control the bottom of the container for unloading through a bottom locking device, thereby reducing dust generation during unloading, in order to solve the problem of excessive dust generated when unloading containers from the top and sides using existing front-loading containers.

[0004] To solve the above technical problems, the technical solution of this utility model is as follows: a bulk container based on a reach stacker, including a container body and a reach stacker. The reach stacker is detachably connected to the top of the container body. Hydraulic cylinders with downward-facing output ends are fixedly connected to both sides of the reach stacker. The container body has interlayers on both side walls and a door hinged to the bottom. A rotating shaft is rotatably connected to the middle of the interlayer, and a triangular head is provided at the bottom of the rotating shaft. The door has holes that mate with the triangular head. A telescopic box is fixedly connected to the top of the interlayer, and a sliding groove is fixedly connected to the side wall. The telescopic box is slidably connected to a slide rod. A spring is fixedly connected between the protruding part of the slide rod and the bottom of the telescopic box. An L-shaped connecting rod is rotatably connected to the side wall of the interlayer via a crossbar. One end of the L-shaped connecting rod is slidably connected to the lower end of the slide rod, and the other end is slidably connected to a push rod. A slider is fixedly connected to the middle of the push rod, and the output end is hinged to the rotating shaft via a linkage mechanism. The slider is slidably connected to the slide groove. A limit mechanism is fixedly connected between the box door and the side wall of the box body. The top of the slide rod is located directly below the output end of the hydraulic cylinder.

[0005] Furthermore, the limiting mechanism includes a limiting groove, in which a limiting slider is slidably connected. One end of the limiting slider is hinged to a limiting rod, and the other end of the limiting rod is hinged to the box door.

[0006] Furthermore, the box door is configured as a double-door structure with holes in the middle of both doors for the triangular head to pass through and rotate.

[0007] Furthermore, the top of the rotating shaft is rotatably connected to the side wall of the housing via a bearing, and the bottom is rotatably connected to the rigid frame at the bottom of the housing.

[0008] Furthermore, the telescopic box is configured with a structure that is thinner at the top and thicker at the bottom, and the upper end of the slide rod is provided with an annular protrusion, which is slidably connected in the thicker cavity at the lower end of the telescopic box.

[0009] Furthermore, the L-shaped connecting rod has strip-shaped holes at both ends, and both the sliding rod and the push rod are connected to the strip-shaped holes at both ends of the L-shaped connecting rod through round rods.

[0010] This utility model has the following advantages compared with the prior art:

[0011] 1. This utility model, by setting up a sandwich layer on both sides of the container body, with a transmission mechanism installed in the sandwich layer and a triangular head at the bottom for locking, enables bottom unloading of the container by front-mounted crane. When unloading in the train car, the container is first placed into the train car, then the bottom locking device is opened, and the container is slowly raised by slowly lifting the front-mounted crane, allowing the loose material to slowly fall along the inner wall of the container, thus achieving relatively static unloading and greatly reducing dust generation. By setting a hydraulic cylinder at the position of the slide bar, with the output end of the hydraulic cylinder opposite to the top position of the slide bar, the bottom door of the container can be locked and opened by the hydraulic cylinder.

[0012] 2. This utility model achieves a change in the direction of force transmission by setting an L-shaped connecting rod. The connecting rod mechanism facilitates the rotation of the rotating shaft by 90 degrees. The limiting mechanism prevents the door from opening vertically downwards at a 90-degree angle to the bottom surface of the box, which would make closing the door after unloading inconvenient. It also facilitates closing the bottom door. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 5The illustrated bulk container based on a reach stacker includes a container body 1 and a reach stacker 2. The reach stacker 2, also known as a container reach crane, consists of three parts: an engineering machinery chassis, a telescopic boom, and a container spreader. The container spreader is snapped into the top of the container body 1, which is open at the top. Four latches are located at the four corners of the container body 1, and corresponding latches are located at the four corners of the reach stacker 2. Lifting is achieved through the detachable connection between the latches and the latches. This structure is prior art, and the reach stacker 2 is also prior art, so it will not be described in detail in this application. To provide power, hydraulic cylinders 16 with downward-facing output ends are installed on both sides of the container spreader of the reach stacker 2. The hydraulic pipes of the hydraulic cylinders 16 are connected to the hydraulic system on the reach stacker 2. The connection provides power to the hydraulic cylinder. The hydraulic cylinder 16 is located inside the side of the front-facing crane 2, with its output end extending out and positioned at the same level as the top of the slide rod 13. The extension of the hydraulic cylinder 16 allows it to contact the top of the slide rod 13, ensuring that the output end of the hydraulic cylinder 16 contacts the top of the slide rod 13 and pushes the slide rod 13 downwards. Simultaneously, it drives the rotating shaft 4 to rotate 90 degrees. To facilitate the installation of the locking mechanism, a layer 10 is provided on one side wall of the housing 1. To improve the support force at the bottom of the housing 1, a rigid frame is provided at the bottom. The doors 3 are hinged to the sides of the rigid frame via horizontally arranged rotating rods. To achieve self-locking, a rotating shaft 4 is rotatably connected in the middle of the layer 10. A triangular head 41 is provided at the bottom of the rotating shaft 4. The triangular protrusions on both sides have the same thickness as the diameter of the rotating shaft 4, ensuring they can pass through the narrow hole at the top of the box door 3. The box door 3 has a hole that mates with the triangular head 41. The hole is designed so that its upper end matches the diameter of the rotating shaft 4, and its lower end is conical, ensuring that the triangular head 41 does not rub against the upper hole after rotating 90 degrees. To facilitate the rotation of the rotating shaft 4, a stop block is fixedly connected to one side wall at the upper end of the rotating shaft 4. The stop block is fixedly connected to the rear side wall of the rotating shaft 4. To enable the rotating shaft 4 to have an automatic rotation function, a telescopic box 14 is fixedly connected to the top of the interlayer 10, and a slide groove 7 is fixedly connected to the side wall. A slide rod 13 is slidably connected inside the telescopic box 14, and a spring is fixedly connected between the protruding part of the slide rod 13 and the bottom of the telescopic box 14. Spring 15, under the action of the spring force, allows the slide rod 13 to spring back upward after the applied pressure is released, thereby driving the push rod 9 to move to the right, causing the rotating shaft 4 to rotate 90 degrees. To facilitate the change of the direction of force transmission, an L-shaped connecting rod 11 is rotatably connected to the side wall of the interlayer 10 via a crossbar 12. One end of the L-shaped connecting rod 11 is slidably connected to the lower end of the slide rod 13, and the other end is slidably connected to the push rod 9. To ensure that the push rod 9 moves in the horizontal direction, a slider 8 is fixedly connected to the middle of the push rod 9, and the output end is hinged to the stop block. To avoid motion interference when the rotating shaft 4 rotates, a linkage mechanism is provided at the hinge point between the push rod 9 and the stop block. The linkage mechanism consists of a long rod and a short rod. A long rod is hinged to the output end of the push rod 9, and a short rod is hinged to the other end of the long rod.The short rod is hinged to the stop block, ensuring that the hinge point between the short rod and the long rod does not collide with the side wall of the interlayer 10. The slider 8 is slidably connected to the slide groove 7, facilitating the left and right movement of the push rod 9. To prevent the opening angle of the two door panels from exceeding ninety degrees when the box door 3 is opened for unloading, thus preventing the box door 3 from failing to close after unloading, a limiting mechanism is fixedly connected between the box door 3 and the side wall of the box body 1. The limiting mechanism can limit the opening angle of the box door 3 to no more than ninety degrees when it is opened.

[0021] It should be noted that, in order to facilitate closing the container door 3 after unloading, a bracket is provided to cooperate with the door 3. The bracket is a rectangular bracket welded from square steel pipes, with two stops fixedly connected to the middle of the upper end of the bracket. The two stops are on the same plane. After unloading is completed, the reach crane is operated to move the container above the bracket, and then the container is gradually lowered until the lower side of the open door 3 at the bottom of the container contacts the stops of the bracket. The container is then lowered until the bottom door 3 is closed. At this point, the output end of the hydraulic cylinder 16 retracts, the triangular head 41 resets, and the door 3 is locked. Alternatively, the door 3 can be closed directly on a flat surface, in which case the flat surface will replace the support function of the bracket.

[0022] In order to better close the box door 3 after the unloading is completed, a limiting mechanism is set to limit the maximum opening angle of the box door 3 to not exceed 90 degrees. The limiting mechanism includes a limiting groove 17, a limiting slider 5 is slidably connected in the limiting groove 17, a limiting rod 6 is hinged to one end of the limiting slider 5, and the other end of the limiting rod 6 is hinged to the box door 3.

[0023] To facilitate unloading, the container door 3 is designed as a double-door structure with holes in the middle of both doors 3 for the triangular head 41 to pass through and rotate. When the two doors 3 are closed, a complete hole is formed in the middle that can cooperate with the triangular head 41.

[0024] In order to minimize the frictional force during rotation, the top of the rotating shaft 4 is rotatably connected to the side wall of the housing 1 via a bearing, and the bottom is rotatably connected to the rigid frame at the bottom of the housing 1.

[0025] To ensure that the slide rod 13 retracts when it is pressed down, the telescopic box 14 is designed with a narrower top and a wider bottom. The upper end of the slide rod 13 has an annular protrusion that slides within the wider cavity at the lower end of the telescopic box 14. The top of the slide rod 13 is located directly below the output end of the hydraulic cylinder 16. It should also be noted that the spring 15 is a consumable component; it should be replaced promptly during routine maintenance of the container to ensure the proper functioning of the device.

[0026] In order to avoid motion interference when the L-shaped connecting rod 11 rotates around the crossbar 12, strip holes are provided at both ends of the L-shaped connecting rod 11. The slide rod 13 and the push rod 9 are both connected to the strip holes at both ends of the L-shaped connecting rod 11 through round rods.

[0027] It should be noted that in this embodiment, the lengths of the slide bar 13, L-shaped connecting rod 11, push rod 9, and crank-slider mechanism are adaptively adjusted according to the actual size of the container, and it is necessary to ensure that the slide bar 13 is lowered to a certain height so that the rotating shaft 4 rotates 90 degrees.

[0028] The specific working process of this utility model is as follows:

[0029] When a container loaded with bulk cargo needs to be unloaded, first engage the container spreader of the front crane 2 with the container body 1, so that the output end of the hydraulic cylinder 16 is aligned with the top of the slide rod 13. Place the container body 1 into the bottom of the train car. At this time, activate the extension of the hydraulic cylinders 16 on both sides, causing the output end of the hydraulic cylinder 16 to push the slide rod 13 downward. At this time, the spring 15 is compressed, and the lower end of the slide rod 13 pushes the right end of the L-shaped connecting rod 11 downward. At this time, the left end of the L-shaped connecting rod 11 rotates upward, thereby pushing the push rod 9 to move to the left. The output end of the push rod 9 drives the linkage mechanism to move. The long rod and the short rod of the linkage mechanism are folded and hinged relative to each other. The push rod 9 pushes the long rod to move to the left, and the long rod pushes the short rod to move. The short rod is hinged to the rotating shaft through the stop block, thereby driving the rotating shaft 4 to rotate 90 degrees and keeping the hydraulic cylinder 16 at its extended length. At this time, the protruding part of the triangular head 41 rotates to the longitudinal position, and the container door 3 is no longer affected by the triangular head. Supported by 41, the container slowly opens, gradually lifting the container body 1. The container door 3 opens slowly under the weight of the internal bulk materials, allowing the bulk materials to fall into the train car until the goods are completely unloaded. The container is then lifted out of the train car. Due to the limiting mechanism, the opening angle of the two doors 3 is less than 90 degrees. The container body 1 is placed on the bracket that matches the door 3, and the container body 1 is slowly lowered. After the door 3 contacts the bracket stop, it begins to close under force until the door 3 is closed. At this point, the hydraulic cylinder 16 retracts, and the slide bar 13 moves upward under the elastic force of the spring 15, causing the rotating shaft 4 to rotate 90 degrees. The triangular head 41 continues to engage with the hole in the door 3 to lock the door 3. By following the above steps, the bulk materials can be unloaded from the bottom of the container, and the container body 1 can be slowly lifted by the front crane to achieve static unloading, thereby reducing the spread of dust.
