Description

Technical Field

[0001] This utility model relates to production equipment used in the pharmaceutical, chemical and other industries, and in particular to a hoisting device for flammable and explosive materials. Background Technology

[0002] In industries such as pharmaceuticals and chemicals, materials are frequently transferred between different workstations, typically using motors and automated methods such as rolling and sliding. However, when the transferred materials are energetic (flammable and explosive), the production environment must be in an F0 or F1 zone. Traditional automated transfer methods, whether rolling or sliding, generate friction, static electricity, and pressure, which can easily ignite energetic materials and cause safety accidents, thus failing to meet the requirements. Therefore, manual transfer is currently widely used. However, manual transfer is labor-intensive, can only transfer one material carrier at a time, resulting in low efficiency, and exposes workers to dust and pungent odors, posing health risks. Furthermore, energetic solid materials are flammable and explosive, creating safety hazards. Utility Model Content

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Figures 1 to 6 This invention illustrates an embodiment of a hoisting device for flammable and explosive materials. The device includes a hoist 1 and a bracket 2. The hoist 1 has a first guide member 11, and a transfer trolley 3 is mounted on the first guide member 11. The transfer trolley 3 has a cleaning component 31 for cleaning the first guide member 11. The bracket 2 is connected to the transfer trolley 3. The first guide member 11 can be, for example, a guide rail or guide groove. The cleaning component 31 is preferably a nozzle that sprays high-pressure airflow for cleaning. Alternatively, the cleaning component 31 can be a vacuum nozzle that uses negative pressure to absorb and concentrate dust, thus achieving the purpose of cleaning the first guide member 11. Preferably, the transfer trolley 3 and the bracket 2 are connected by a floating joint, which, compared to a rigid connection, helps to avoid mutual interference between the movements of the transfer trolley 3 and the bracket 2.

[0031] This embodiment of the hoisting device for flammable and explosive materials includes a transfer trolley 3 that can move along the first guide member 11, thereby moving the bracket 2 connected to the transfer trolley 3 and the material carrier 5 on the bracket 2. The first guide member 11 provides guidance for the transfer trolley 3, making the movement process smoother and more stable. The cleaning component 31 on the transfer trolley 3 cleans the first guide member 11, which helps prevent dust from adhering to the first guide member 11 and avoids friction and compression between the transfer trolley 3 and energetic dust during movement, thus preventing an explosion. It has good safety, a simple overall structure, a high degree of automation, and good reliability, which helps reduce labor intensity and improve efficiency.

[0032] See details Figure 4 In this embodiment, the transfer trolley 3 is provided with a traveling wheel 32 located on the top surface of the first guide member 11 and a limiting wheel 33 located on the inner side of the first guide member 11. The traveling wheel 32 enables the transfer trolley 3 to move along the first guide member 11, reducing frictional resistance, while the limiting wheel 33 plays a limiting role, preventing the transfer trolley 3 from deviating, and further improving reliability.

[0033] Furthermore, in this embodiment, the cleaning component 31 includes a first cleaning component 311 for cleaning the top surface of the first guide member 11 and a second cleaning component 312 for cleaning the inner side surface of the first guide member 11. The first cleaning component 311 and the second cleaning component 312 clean the top surface and the side surface of the first guide member 11 respectively, avoiding friction and compression between the traveling wheel 32 and the limiting wheel 33 and energetic dust, which could cause an explosion, thus ensuring good safety.

[0034] Furthermore, in this embodiment, the transfer trolley 3 is equipped with a hydraulic motor 34, the output end of which is connected to the input end of the reducer 35. The traveling wheels 32 include at least one set of drive wheels, which are connected to the output end of the reducer 35. After being reduced in speed by the reducer 35, the output end of the hydraulic motor 34 drives the drive wheels to rotate, thereby enabling the transfer trolley 3 to move along the first guide member 11. Compared to an electric motor, the hydraulic motor 34 is more suitable for energetic materials, thus avoiding the risk of explosion.

[0035] See details Figure 1 In this embodiment, the hoisting device for flammable and explosive materials also includes a cable chain 4. The hoist 1 is equipped with a support beam 12 and multiple support rollers 13 to support the cable chain 4. One end of the cable chain 4 is connected to the transfer trolley 3. The cable chain 4 facilitates the arrangement of cables, air hoses, and oil hoses, and prevents them from becoming entangled as they move with the transfer trolley 3. The support beam 12 and support rollers 13 provide reliable support for the cable chain 4, and when the cable chain 4 extends or retracts, there is rolling friction between the support rollers 13 and the cable chain 4, resulting in low frictional resistance.

[0036] See details Figure 3 , Figure 5 and Figure 6In this embodiment, the bracket 2 is provided with a second guide 21 and a positioning component 22 for preventing the material carrier 5 from moving along the second guide 21. The second guide 21 is located in a water tank 24, and at least one end of the water tank 24 is provided with a water-stopping component 25 that can float up and down. The material carrier 5 moves into the bracket 2 along the second guide 21. The water in the water tank 24 can clean and lubricate the second guide 21, reduce dust adhesion to the second guide 21, and keep the second guide 21 moist, which helps to reduce friction between it and the material carrier 5, and significantly reduces the explosion risk of energetic solid materials. At least one end of the water tank 24 is provided with a water-stopping component 25 that can float up and down. When the material carrier 5 needs to move to or away from the second guide 21, it can squeeze the water-stopping component 25 to make it sink, thereby passing smoothly and reducing friction and squeezing between the material carrier 5 and the water-stopping component 25, reducing the explosion risk. After the material carrier 5 passes through, the water-stopping component 25 floats up, reducing water overflow from the water tank 24 and keeping the second guide component 21 submerged in water. After the material carrier 5 is positioned on the bracket 2, the positioning component 22 positions the material carrier 5 to prevent accidental movement during hoisting. Preferably, the water-stopping component 25 is a water-stopping block. Of course, in other embodiments, the water-stopping component 25 can also be a baffle or the like. Springs or other components can be installed below the water-stopping component 25 to achieve vertical floating, resulting in a simple and reliable structure.

[0037] In a preferred embodiment, the second guide 21 is arranged perpendicularly to the first guide 11. After the material carrier 5 moves into place along the second guide 21, the transfer trolley 3 drives the bracket 2 and the material carrier 5 to move along the first guide 11 as a whole, thereby changing the moving direction of the material carrier 5 by 90°, which facilitates the transfer of the material carrier 5 between different workstations.

[0038] Furthermore, in this embodiment, the positioning component 22 includes a first positioning cylinder 221 and a second positioning cylinder 222, which are spaced apart along the length of the second guide member 21. When the material carrier 5 needs to move along the second guide member 21, the piston rods of the first positioning cylinder 221 and the second positioning cylinder 222 retract to avoid obstruction. After the material carrier 5 is in place, the piston rods of the first positioning cylinder 221 and the second positioning cylinder 222 extend, preventing the object from continuing to move along the second guide member 21. The structure is simple and reliable. Compared to a motor, the first positioning cylinder 221 and the second positioning cylinder 222 are more suitable for energetic materials, preventing explosions.

[0039] Furthermore, in this embodiment, both the first positioning cylinder 221 and the second positioning cylinder 222 are arranged in the vertical direction. The vertical arrangement of the first positioning cylinder 221 and the second positioning cylinder 222 fully utilizes the vertical space of the bracket 2. Of course, in other embodiments, the first positioning cylinder 221 and the second positioning cylinder 222 can also be arranged horizontally on the side of the second guide member 21, but this would increase the width dimension of the bracket 2.

[0040] Furthermore, in this embodiment, the top of the bracket 2 is provided with a cover plate 26, which is connected to the transfer trolley 3. The cover plate 26 can serve as a shield to prevent dust generated by solid materials from floating onto the first guide member 11 and the transfer trolley 3, thereby improving safety. On the other hand, it serves as a connector to realize the connection between the bracket 2 and the transfer trolley 3.

[0041] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
