Description

Technical Field

[0001] This invention relates to a broken rail structure for a fireproof and explosion-proof system. Background Technology

[0002] One of the main raw materials for brewing is grains (such as wheat, rice, and corn). These grains generate a large amount of dust during processing. When the dust reaches a certain concentration in the air, it may cause an explosion when it encounters a source of ignition or high temperature. The fermentation process of brewing produces alcohol and carbon dioxide. Alcohol is a flammable substance, which increases the risk of explosion when it encounters a source of ignition. Therefore, fire prevention and explosion protection measures are taken in brewing production lines. For example, fireproof roller shutters are installed between the production area and the office area or warehouse. Fireproof roller shutters can be quickly lowered in the event of a fire to prevent the fire from spreading to the office area or warehouse, protecting personnel safety and important materials.

[0003] In brewing production lines, yeast (koji) must first be made, then manually transported to fermentation containers for fermentation. These fermentation tanks are of a certain height. If only manual transport is used, only a small amount of yeast can be carried to the top of the tank at a time and poured into the fermentation vessel. This method of yeast transport is inefficient and affects the overall production schedule. To improve efficiency, existing technologies incorporate overhead logistics (EMS) conveying equipment, including suspended conveyor tracks and self-propelled trolleys. The self-propelled trolleys automate the transport of the fermentation tanks. However, since the conveyor tracks are suspended, and fireproof roller shutters need to be pulled to the ground in case of fire, a key technical problem that needs to be solved in existing brewing production lines is how to allow the self-propelled trolleys to pass smoothly under the fireproof roller shutters during normal production and how to ensure the fireproof roller shutters are lowered without interfering with the conveyor tracks in case of fire. Summary of the Invention

[0004] This invention provides a broken track structure for a fireproof and explosion-proof system, which allows a self-propelled trolley to pass smoothly under a fireproof roller shutter during normal brewing production, and enables the fireproof roller shutter to be lowered smoothly without interfering with the conveyor track in the event of a fire.

[0005] To solve the above problems, the broken rail structure of the fireproof and explosion-proof system provided by the present invention adopts the following technical solution:

[0006] The fireproof and explosion-proof system includes a broken rail structure comprising a first fixed rail, a second fixed rail, and a movable rail extending in the same direction. The movable rail is positioned between the first and second fixed rails and slides in a guide engagement with the second fixed rail. A drive unit is provided on the second fixed rail, and the drive end of the drive unit is connected to the movable rail to drive the movable rail to move back and forth. When the drive unit drives the movable rail to a position aligned with the end of the second fixed rail, a passage for the fireproof roller shutter door to fall is formed between the end of the movable rail away from the second fixed rail and the corresponding end of the first fixed rail. When the drive unit drives the movable rail to a position aligned with the end of the first fixed rail, a self-propelled trolley can pass through the first fixed rail, the movable rail, and the second fixed rail.

[0007] Beneficial effects: This invention drives the movable track to move through a driving component, enabling the movable track to connect with the first and second fixed tracks during normal brewing production, ensuring that the self-propelled trolley can smoothly pass through each track; in the event of a fire, the movable track is disconnected from the first fixed track, forming a passage for the fireproof roller shutter to be lowered, ensuring that the fireproof roller shutter can normally perform its fireproof function.

[0008] Furthermore, the upper and lower wing plates of the movable track are each integrally formed with two spaced guide plates, and the corresponding two guide plates form a first U-shaped guide groove with the corresponding wing plate on the movable track; the upper and lower wing plates of the second fixed track are each provided with two guide slots for the corresponding guide plates to be inserted, and the portions of the upper and lower wing plates of the second fixed track located between the two guide slots are inserted into the first U-shaped guide groove; a reinforcing support plate is connected to the lower wing plate of the second fixed track, and the reinforcing support plate is used to support and contact the guide plates on the lower wing plate of the movable track when the movable track moves.

[0009] Beneficial effects: By connecting the guide slot with the first U-shaped guide groove, the movable track has good guidance when moving and will not deviate. The reinforced support plate can enhance the structural strength at the break point between the first fixed track and the second track, ensuring that the trolley can pass smoothly and stably.

[0010] Furthermore, the outer edges of the two guide plates located on the upper side are flush with the outer edge of the upper wing plate of the movable track, and the outer edges of the two guide plates located on the lower side are flush with the outer edge of the lower wing plate of the movable track; the guide port is L-shaped.

[0011] Beneficial effect: The guide slot is located at the outer edge of the second fixed track, while the self-propelled trolley passes through the inner side of the guide slot, which can avoid affecting the normal movement of the self-propelled trolley.

[0012] Furthermore, the driving component is an electric cylinder, and the movable track is provided with a connecting plate that is fixedly connected to the telescopic rod of the electric cylinder.

[0013] Beneficial effects: Electric cylinders have a simple structure and can precisely control speed, position and force, making the movement of the moving track more stable and accurate.

[0014] Furthermore, a guide plate is connected to the upper wing plate of the movable track, and the connecting plate is vertically connected to the guide plate. A second U-shaped guide groove is provided on the side of the guide plate near the second fixed track. The second U-shaped guide groove passes through the upper wing plate of the movable track in the vertical direction. A guide block is connected to the upper wing plate of the second fixed track and slides in accordance with the second U-shaped guide groove. When the driving component drives the movable track to move to a position aligned with the end of the second fixed track, the guide block abuts against the bottom of the second U-shaped guide groove, the upper and lower wing plates of the second fixed track abut against the bottom of the corresponding first U-shaped guide groove, and the guide plate body abuts against the bottom of the corresponding guide socket.

[0015] Beneficial effect: Further improves the stability of the moving track.

[0016] Furthermore, at least two parallel and spaced reinforcing plates are connected between the guide plate and the connecting plate.

[0017] Beneficial effects: Ensures the structural strength of the guide plate and improves the stability of the drive components during operation.

[0018] Furthermore, when the driving component drives the movable track to a position aligned with the end of the first fixed track, the guide plate makes support contact with the upper wing plates of both the first and second fixed tracks.

[0019] Beneficial effects: When the guide plate and the reinforcing plate are used together, the force exerted by the automatic trolley on the moving track can be distributed to different positions when the trolley passes through the moving track, thereby improving the stability of the entire structure.

[0020] Furthermore, the end of the guide plate near the first fixed track has a chamfer.

[0021] Beneficial effect: When the moving track is restored, the chamfer can reduce the friction between the guide plate and the upper wing plate of the first fixed track. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0032] Embodiment 1 of the broken rail structure of the fireproof and explosion-proof system provided by the present invention:

[0033] like Figure 1 and Figure 2 As shown, the broken rail structure of the fireproof and explosion-proof system includes a first fixed rail 1, a second fixed rail 2, and a movable rail 3 extending in the same direction. Both the first fixed rail 1 and the second fixed rail 2 are I-beam rails. The movable rail 3 is located between the first fixed rail 1 and the second fixed rail 2 and slides in a guide engagement with the second fixed rail 2.

[0034] Specifically, such as Figure 5As shown, a fixing plate 17 is vertically welded to the upper wing plate of the second fixed track 2, and a driving component is fixed on the fixing plate 17. In this embodiment, the driving component is an electric cylinder 7 commonly used in the prior art.

[0035] like Figure 3 As shown, the movable track 3 includes an I-beam shaped track body. Two spaced-apart guide plates 4 are integrally formed on the upper and lower flanges of the track body. The outer edges of the two upper guide plates 4 are flush with the outer edges of the upper flange of the track body, and the outer edges of the two lower guide plates 4 are flush with the outer edges of the lower flange of the movable track 3. First U-shaped guide grooves 9 are formed between the two upper guide plates and the upper flange of the track body, and between the two lower guide plates and the lower flange of the track body.

[0036] The upper and lower wing plates of the second fixed track 2 are each provided with two guide slots 5 for the corresponding guide plates 4 to be inserted. The guide slots 5 are L-shaped. The portions of the upper and lower wing plates of the second fixed track 2 located between the two guide slots 5 are correspondingly inserted into the first U-shaped guide groove 9 mentioned above.

[0037] A guide plate 14 is connected to the upper wing plate of the movable track 3. A connecting plate 18, which is vertically welded to the guide plate 14 and arranged opposite to the fixed plate 17, is also connected to the telescopic rod of the electric cylinder 7. Two parallel and spaced reinforcing plates 15 are welded to the side of the connecting plate 18 facing away from the fixed plate 17 and the guide plate 14. A second U-shaped guide groove 10 is provided on the side of the guide plate 14 near the second fixed track 2. The second U-shaped guide groove 10 passes through the upper wing plate of the movable track 3 in the vertical direction. A guide block 12 is connected to the upper wing plate of the second fixed track 2 and slides in a guide-sliding fit with the second U-shaped guide groove 10. The end of the guide plate 14 near the first fixed track 1 also has a chamfer 16. A reinforcing support plate 13 is connected to the lower wing plate of the second fixed track 2. The reinforcing support plate 13 is used to maintain contact with the guide plate body 4 on the lower wing plate of the movable track 3 when the movable track 3 moves.

[0038] The electric cylinder 7 can drive the movable track 3 to move back and forth along the second fixed track 2, and the electric cylinder 7 can drive the movable track 3 to two extreme positions. The first extreme position is when the movable track 3 moves to a position aligned with the end of the second fixed track 2, such as... Figure 2As shown, at this time, the end of the movable track 3 furthest from the second fixed track 2 forms a passage 6 for the fireproof roller shutter door to fall between the corresponding end of the first fixed track 1 and the movable track 3. The movable track 3 is disconnected from the first fixed track 1. The guide block 12 abuts against the bottom of the second U-shaped guide groove 10. The portions of the upper and lower wing plates of the second fixed track 2 located between the two guide slots 5 abut against the bottom of the corresponding first U-shaped guide grooves 9. The guide plate 4 abuts against the bottom of the corresponding guide slot 5. The second extreme position is when the movable track 3 moves to a position aligned with the end of the first fixed track 1, as shown. Figure 1 As shown, the guide plate 14 is in contact with the upper wing plates of the first fixed track 1 and the second fixed track 2, and the reinforcing support plate 13 is in contact with the guide plate body 4. The self-propelled trolley can pass normally on the first fixed track 1, the movable track 3 and the second fixed track 2.

[0039] When the brewing production line is operating normally, such as Figure 1 As shown, the movable track 3 is in its second extreme position, the fireproof roller shutter door is in the retracted state, and the electric cylinder 7 is in the extended state. The self-propelled trolley can smoothly pass through the first fixed track 1, the movable track 3, and the second fixed track 2. In the event of a fire in the brewing production line, the electric cylinder 7 retracts, driving the movable track 3 towards the second fixed track 2 until the movable track 3 moves to its first extreme position. At this point, the movable track 3 disconnects from the first fixed track 1, forming a passage 6 for the fireproof roller shutter door to pass through. Figure 2 As shown, the fireproof roller shutter door is driven by an electric device and automatically lowers to pass through the aforementioned passage 6 to block smoke and ensure personnel safety.

[0040] Embodiment 2 of the broken rail structure of the fireproof and explosion-proof system provided by the present invention:

[0041] The main difference between this embodiment and Embodiment 1 is that in Embodiment 1, the driving component is an electric cylinder. In this embodiment, the driving component is a hydraulic cylinder. Of course, in other embodiments, the driving component can also be a pneumatic cylinder. Alternatively, in other embodiments, the driving component is a drive motor, in which case a transmission structure is provided between the drive motor and the movable track. For example, the output end of the drive motor is connected to a gear, and the guide plate is provided with a rack that meshes with the gear. When the drive motor is turned on, the gear rotates, and the drive rack drives the movable track to move.

[0042] Embodiment 3 of the broken rail structure of the fireproof and explosion-proof system provided by the present invention:

[0043] The main difference between this embodiment and Embodiment 1 is that in Embodiment 1, the guide port is L-shaped, and the guide plate is flush with the outer edge of the corresponding upper or lower wing plate. In this embodiment, the guide port is U-shaped, and correspondingly, there is a certain distance between the guide plate and the outer edge of the corresponding upper or lower wing plate. However, to avoid the guide port affecting the movement of the self-propelled vehicle, the guide port is located outside the wheel travel path of the self-propelled vehicle.
