Description

Technical Field

[0001] This utility model relates to the field of malt transport equipment door opening and closing technology, specifically a device for opening and closing the door of a malt transport tilting container. Background Technology

[0002] In containerized transport of bulk malt, a common loading method involves using a container tilter to tilt a standard container 90 degrees vertically, opening the door upwards, and then loading the malt through the loading pipe. Once full, the door is closed, and the container is tilted back to a horizontal position for transport. This method is fast and maximizes container capacity utilization. However, once the container is upright, the door becomes heavy due to gravity. Current practices involve using a manual hoist hook above the loading pipe, which operators pull to open the door. This process is not only labor-intensive, increasing workload and reducing efficiency, but also poses serious safety hazards. Operators may forget to remove the manual hoist hook after loading and operate the tilter directly, causing damage to the hook, loading pipe, and door during tilting, potentially leading to more serious accidents. Therefore, a new auxiliary device needs to be designed to simplify door opening and closing operations, effectively prevent misoperation, and ensure equipment and personnel safety. Utility Model Content

[0003] This invention provides a device for opening and closing the doors of a malt transport container, which solves the problem that the opening and closing of the doors of existing bulk malt containers is manually operated when loading malt, which increases labor intensity, reduces work efficiency, and poses serious safety hazards.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for opening and closing the door of a malt transport container, comprising a container tilting device, a container, and a bulk material pipe. The container tilting device is used to tilt the container, and the bulk material pipe is used to transport malt into the container. A mounting bracket is fixedly installed on the top of the factory building, above the container tilting device. Mounting plates are arranged opposite each other on both sides of the bulk material pipe, and the mounting plates are fixedly connected to the mounting bracket. A mounting column is vertically installed on the mounting plate, and the mounting column is stepped. An electric hoist is detachably installed at the bottom of the mounting column, and a hook is installed at the bottom of the chain of the electric hoist. The hook is detachably connected to the container door for opening the container door. A proximity switch is located at the bottom of the mounting bracket near the mounting column. The proximity switch is electrically connected to the container tilting device. The electric hoist drives the device to replace manual labor, improving efficiency, supporting remote control, avoiding safety hazards of high-altitude operations, and determining the opening and closing status of the container door through the proximity switch, thereby triggering the container tilting device and reducing the risks caused by improper operation.

[0005] As a supplement to the technical solution described in this utility model, the proximity switch is fixedly mounted on the lower side of the mounting plate by a fixed bracket. The fixed bracket is provided with a long strip-shaped mounting groove, and the proximity switch can be moved up and down along the mounting groove for adjustment.

[0006] As a supplement to the technical solution described in this utility model, an installation ring is fixedly provided at the lower end of the installation column, and a U-shaped shackle is provided inside the installation ring. The U-shaped shackle and the installation ring are detachably connected, which facilitates the installation of the electric hoist.

[0007] As a supplement to the technical solution described in this utility model, the upper end of the electric hoist is fixedly provided with an installation shaft, which is detachably connected to a U-shaped shackle. The bolt on the U-shaped shackle passes through the installation shaft to fix the electric hoist on the U-shaped shackle.

[0008] As a supplement to the technical solution described in this utility model, a fixing sleeve is threadedly connected to the upper part of the mounting column, and a spring is sleeved on the mounting column between the fixing sleeve and the mounting plate. The mounting column is kept raised by the spring force. When the mounting column is subjected to a downward force and moves down, the proximity switch can send a stop signal.

[0009] As a supplement to the technical solution described in this utility model, the mounting bracket includes two horizontal beams arranged side by side, the two ends of the two horizontal beams are connected by a first vertical beam, a second vertical beam is arranged in the middle of the two horizontal beams, the material distribution pipe is fixedly arranged on the second vertical beam, and the mounting bracket is fixed to the top of the factory building to support and fix other components. It has high structural strength and is easy to process.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] With a simple structure and convenient operation, this device replaces the heavy labor previously required for manually operating the container doors in a semi-automatic manner. Operators only need to activate the device to open and close the doors, significantly reducing operation time and physical exertion, thereby greatly improving the overall efficiency of loading and unloading operations. Through proximity switches, accidents caused by forgetting to remove the hooks from the container doors during the overturning process, such as equipment damage or personnel injury, are effectively prevented, reducing the danger and labor intensity of manual operation and improving operational safety and efficiency. This solution addresses the problem of existing bulk malt containers requiring manual operation for opening and closing doors, which increases labor intensity, reduces operational efficiency, and poses serious safety hazards.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] The present invention relates to a device for opening and closing the door of a tilting container used in malt transportation, such as... Figure 1-6As shown, the system includes a container tilting device 1, a container 2, and a bulk material pipe 3. The container tilting device 1 is used to tilt the container 2, and the bulk material pipe 3 is used to feed malt into the container 2. A mounting bracket 4 is fixedly installed on the top of the factory building, above the container tilting device 1. Mounting plates 5 are arranged opposite each other on both sides of the bulk material pipe 3, and the mounting plates 5 are fixedly connected to the mounting bracket 4. A mounting column 6 is vertically installed on the mounting plate 5, and the mounting column 6 is stepped. An electric hoist 7 is detachably installed at the bottom of the mounting column 6. The electric hoist 7 can be purchased directly from the market. Since the electric hoist 7 is existing technology, its structure will not be described in detail. The brand of the electric hoist 7 can be found in KO. The electric hoist 7 has a hook 8 installed at the bottom of its chain. The hook 8 can be purchased directly from the market and is equipped with an anti-disengagement hook. The hook 8 can be detachably connected to the container door 21 to open the container door 21. A proximity switch 9 is located at the bottom of the mounting bracket 4 near the mounting column 6. The proximity switch 9 is electrically connected to the container tilting device 1. The electric hoist 7 drives the device to replace manual labor, improving efficiency, supporting remote control, and avoiding safety hazards of working at height. The proximity switch 9 determines the open or closed state of the container door 21 and triggers the container tilting device 1, reducing the danger and labor intensity of manual operation and improving the safety and efficiency of operation.

[0022] In this embodiment, as Figure 5 As shown, the proximity switch 9 is fixedly mounted on the lower side of the mounting plate 5 by a fixing bracket 10. The fixing bracket 10 is provided with a long strip-shaped mounting groove 101, and the proximity switch 9 can be moved up and down along the mounting groove 101 for adjustment.

[0023] In this embodiment, as Figure 3 As shown, an installation ring 11 is fixedly provided at the lower end of the installation column 6, and a U-shaped shackle 12 is provided inside the installation ring 11. The U-shaped shackle 12 and the installation ring 11 are detachably provided to facilitate the installation of the electric hoist 7.

[0024] In this embodiment, as Figure 3 As shown, the upper end of the electric hoist 7 is fixedly provided with an installation shaft 71. The installation shaft 71 is detachably connected to the U-shaped shackle 12. The bolt on the U-shaped shackle 12 passes through the installation shaft 71 to fix the electric hoist 7 on the U-shaped shackle 12.

[0025] In this embodiment, as Figure 3 and Figure 4As shown, a fixing sleeve 61 is threadedly connected to the upper part of the mounting post 6. A spring 13 is sleeved on the mounting post 6 between the fixing sleeve 61 and the mounting plate 5. The mounting post 6 is kept raised by the force of the spring 13. When the electric hoist 7 or the U-shaped shackle 12 is subjected to a downward force, the spring 13 is compressed when the mounting post 6 moves down. The proximity switch 9 can send a stop signal. When the force is removed, the spring 13 can provide a rebound force to reset the mounting post 6, which plays a buffering role.

[0026] In this embodiment, as Figure 2 As shown, the mounting bracket 4 includes two horizontal beams 41 arranged side by side. The two ends of the two horizontal beams 41 are connected by a first vertical beam 42. A second vertical beam 43 is arranged in the middle of the two horizontal beams 41. The material distribution pipe 3 is fixedly arranged on the second vertical beam 43. The mounting bracket 4 is fixed on the top of the factory building and is used to support and fix other components. It has high structural strength and is easy to process.

[0027] In this embodiment, as Figure 1 As shown, the crossbeam 41, the first vertical beam 42, and the second vertical beam 43 are all made of channel steel and welded into a mounting bracket 4, which is fixed to the load-bearing beam on the top of the factory building. The bulk material pipe 3 is welded and fixed on the second vertical beam 43. The mounting bracket 4 is located directly above the container tipping device 1. A mounting plate 5 is welded on the mounting bracket 4. The mounting plate 5 is made of stainless steel and has through holes. The mounting column 6 and the mounting ring 11 are fixedly connected by welding or threaded connection. Then, the mounting column 6 is passed through the through hole of the mounting plate 5 and a spring 13 is sleeved on it. The fixing sleeve 61 is screwed on the top of the mounting column 6. The U-shaped shackle 12 passes through the mounting ring 11. The mounting shaft 71 of the electric hoist 7 is placed in the middle of the U-shaped shackle 12. The bolt passes through the mounting shaft 71 to fix the electric hoist 7 on the U-shaped shackle 12. The proximity switch 9 is installed on the lower side of the mounting plate 5 through the fixing bracket 10. The position of the proximity switch 9 is adjusted by using the long strip mounting groove 101 on the bracket so that the sensing end of the switch senses the lower end of the mounting column 6. The proximity switch 9 is connected to the control box of the container tilting device 1. The proximity switch 9 is normally closed. When the proximity switch 9 senses the lower end of the mounting column 6, its contacts remain closed and the control circuit is normally connected. When the proximity switch 9 does not sense the lower end of the mounting column 6, it directly cuts off the control circuit and the oil pump motor 15 stops running.

[0028] In this embodiment, as Figure 6 As shown, the power supply is connected to the oil pump motor 15 via the first circuit breaker 16, the main contact of the contactor 171, and the thermal relay 18. When the main contact of the contactor 171 is closed, the oil pump motor 15 is powered on and runs. When the main contact of the contactor 171 is open, the oil pump motor 15 is de-energized and stops. The power supply is supplied to the intermediate relay 20 via the second circuit breaker 19 and the DC24V switching power supply 14. The proximity switch 9 is connected to this circuit.

[0029] Start-up procedure: Press the start button 21, the current energizes the coil of contactor 17, the main contact 171 of the contactor closes, the oil pump motor 15 starts, and at the same time the auxiliary contact 172 of the contactor self-locks. After releasing the start button 21, the coil of contactor 17 can still be energized, and the oil pump motor 15 continues to run.

[0030] Stop procedure: Press the stop button 22 to cut off the control circuit of the contactor 17 coil, the main contact 171 of the contactor opens, and the oil pump motor 15 stops due to power failure; if the thermal relay 18 operates due to overload of the oil pump motor 15, its thermal relay contact 181 opens, which will also cut off the coil circuit of the contactor 17, and the oil pump motor 15 stops, thus achieving overload protection.

[0031] Emergency stop procedure: The proximity switch 9 is normally closed. When the proximity switch 9 is activated (the contact is open), the intermediate relay 20 is de-energized, the intermediate relay contact 201 is opened, the coil circuit of the cutting-off contactor 17 is cut off, and the oil pump motor 15 is de-energized and stops.

[0032] In this embodiment, as Figure 1 As shown, the container tilting device 1 is used to tilt the container 2 by 90 degrees. The operator hooks the hook 8 of the electric hoist 7 to the designated position of the container door 21. The electric hoist 7 is started through the control box, so that its chain is tightened and it begins to lift. The lifting of the hook 8 drives the container door 21 to open upward. During this process, the pulling force of the electric hoist 7 is only equivalent to the weight of the container door 21, and it will not cause the spring 13 to be compressed significantly. The normally closed proximity switch 9 does not operate. After the malt is loaded into the container through the bulk material pipe 3, the electric hoist 7 lowers the hook 8, and the container door 21 closes by its own weight, disengaging the hook 8 from the container door 21. If the hook 8 does not disengage after the container door 21 is closed, the container tilting device 1 is operated. The huge pulling force generated by the container door 21 and the hook 8 compresses the spring 13. The electric hoist 7 moves the mounting column 6 downward through the mounting ring 11 and the U-shaped shackle 12. The mounting column 6 is in the shape of a stepped shaft, and the diameter of the lower end of the mounting column 6 is larger than the diameter of the upper end. When the mounting column 6 moves downward, the proximity switch 9 cannot sense the lower end of the mounting column 6. When the proximity switch 9 is activated (the contact is open), the intermediate relay 20 is de-energized, the intermediate relay contact 201 is opened, the coil circuit of the cutting contactor 17 is cut off, and the oil pump motor 15 is de-energized and stops.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
