Description

Technical Field

[0001] This utility model relates to production equipment used in the pharmaceutical, chemical and other industries, and in particular to an explosion-proof push-pull device. Background Technology

[0002] In industries such as pharmaceuticals and chemicals, it is often necessary to automatically push materials to the next process, typically using motors as the drive. However, when the materials being transported are energetic solids (flammable and explosive), the production environment generally needs to be in an F0 or F1 zone, making it impossible or unsuitable to use methods involving electricity (for example, electrical sparks could cause explosions, especially with energetic solids, and dust can also easily lead to safety accidents). Therefore, manual transport is currently the most common method. However, manual transport is labor-intensive, requires only one material carrier at a time, resulting in low efficiency, and dust poses a health hazard to workers. Furthermore, the flammability and explosiveness of energetic solids present safety risks. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An explosion-proof push-pull device includes a bracket, a clamping mechanism, a positioning mechanism, and a push-pull drive component. The positioning mechanism and the push-pull drive component are mounted on the bracket, with the positioning mechanism located below the clamping mechanism. The clamping mechanism includes a first mounting base connected to the push-pull drive component, clamping arms arranged opposite to each other on both sides of the first mounting base, a clamping drive component for driving the clamping arms on both sides to move closer or further apart, and a detection component for detecting whether the clamping arms are clamped or open. The detection component includes a first detection plate mounted on the clamping arms, a second detection plate mounted on the first mounting base, and a nozzle mounted on the second detection plate, with the nozzle facing the first detection plate.

[0006] As a further improvement to the above technical solution: a corrugated sealing cover is connected between the bracket and the first mounting base, and the connection between the push-pull drive component and the first mounting base is located inside the corrugated sealing cover.

[0007] As a further improvement to the above technical solution: a spring air tube is also connected between the bracket and the first mounting base, and the spring air tube is located inside the corrugated sealing cover.

[0008] As a further improvement to the above technical solution: the first mounting base is provided with first guide rods on both sides, the first guide rods are arranged parallel to the push-pull drive component, the bracket is provided with a first guide sleeve, and the first guide rods pass through the spring air tube and the first guide sleeve.

[0009] As a further improvement to the above technical solution: the first mounting base is also provided with rollers on both sides, the bracket is provided with guide rails on both sides, the rollers are arranged correspondingly to the guide rails, and the positioning mechanism is located below the guide rails.

[0010] As a further improvement to the above technical solution: the guide rail is provided in the water tank, and at least one end of the water tank is provided with a water-stopping component that can float up and down.

[0011] As a further improvement to the above technical solution: the clamping arm is provided with a clamping groove.

[0012] As a further improvement to the above technical solution: the clamping drive component is a double-rod cylinder, and the two piston rods of the double-rod cylinder are connected to the clamping arms on both sides in a one-to-one correspondence.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] The explosion-proof push-pull device disclosed in this utility model involves a hoisting mechanism that hoists the material carrier into position, followed by a positioning mechanism that corrects and positions the hoisting mechanism. Then, a push-pull drive pushes out the clamping mechanism until the clamping arms are aligned with the uprights on both sides of the material carrier. At this point, the push-pull drive stops, and the clamping drive moves the clamping arms on both sides closer together to clamp the uprights on both sides of the material carrier. Subsequently, the push-pull drive can push (or pull) the material carrier out of the hoisting mechanism through the clamping mechanism. When it is necessary to release the material carrier, the clamping drive moves the clamping arms on both sides away from each other, separating the clamping arms from the column. Compressed gas is then sprayed from the nozzles towards the first detection plate. The first detection plate moves with the clamping arms. The smaller the distance between the first and second detection plates, the greater the pressure acting on the first detection plate; conversely, the greater the distance, the less pressure. This allows for the determination of whether the clamping arms are clamped or open, further improving the reliability of the clamping mechanism. Compared to conventional electric sensors and electric detection components, the detection component in this invention is more suitable for energetic materials, which helps prevent explosions. Compared to manual handling, the explosion-proof push-pull device disclosed in this invention has a simple overall structure, high degree of automation, and good reliability, which helps reduce labor intensity and improve efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Figures 1 to 8This illustration shows an embodiment of the explosion-proof push-pull device of this utility model. The device includes a bracket 1, a clamping mechanism 3, a positioning mechanism 4, and a push-pull drive component 5. The positioning mechanism 4 and the push-pull drive component 5 are mounted on the bracket 1, with the positioning mechanism 4 located below the clamping mechanism 3. The clamping mechanism 3 includes a first mounting base 33 connected to the push-pull drive component 5, clamping arms 34 arranged opposite to each other on both sides of the first mounting base 33, a clamping drive component 35 for moving the clamping arms 34 closer together or further apart, and a detection component for detecting whether the clamping arms 34 are clamped or open. The detection component includes a first detection plate 36 on the clamping arms 34, a second detection plate 37 on the first mounting base 33, and a nozzle 38 on the second detection plate 37, with the nozzle 38 facing the first detection plate 36. Preferably, the push-pull drive component 5 is a hydraulic cylinder, which is more suitable for energetic materials than a motor, thus preventing explosions.

[0033] In this embodiment of the explosion-proof push-pull device, during operation, after the hoisting mechanism 7 hoists the material carrier 2 into position, the positioning mechanism 4 corrects and positions the hoisting mechanism 7. Then, the push-pull drive 5 pushes out the clamping mechanism 3 until the clamping arm 34 is aligned with the uprights 21 on both sides of the material carrier 2, at which point the push-pull drive 5 stops. See details. Figure 4 The clamping drive 35 drives the clamping arms 34 on both sides to move closer together, so that the clamping arms 34 clamp the columns 21 on both sides of the material carrier 2 one by one. Subsequently, the push-pull drive 5 can push (or pull out) the material carrier 2 from the hoisting mechanism 7 through the clamping mechanism 3. When it is necessary to release the material carrier 2, the clamping drive 35 drives the clamping arms 34 on both sides to move away from each other, so that the clamping arms 34 are separated from the columns 21. The jet nozzle 38 sprays compressed gas toward the first detection plate 36. The first detection plate 36 moves with the clamping arms 34. The smaller the distance between the first detection plate 36 and the second detection plate 37, the greater the pressure on the first detection plate 36. Conversely, the larger the distance between the first detection plate 36 and the second detection plate 37, the smaller the pressure on the first detection plate 36. This allows it to be determined whether the clamping arms 34 are clamped or open, further improving the reliability of the clamping mechanism 3. Compared with conventional electric sensors and electric detection components, the detection component in this embodiment is more suitable for energetic materials, which is beneficial to preventing explosions and has good safety. Compared to manual transport, the explosion-proof push-pull device in this embodiment has a simple overall structure, a high degree of automation, and good reliability, which helps to reduce labor intensity and improve efficiency.

[0034] See details Figure 1In this embodiment, a corrugated sealing cover 61 is connected between the bracket 1 and the first mounting base 33, and the connection between the push-pull drive component 5 and the first mounting base 33 is located inside the corrugated sealing cover 61. The corrugated sealing cover 61 achieves sealing isolation at the connection between the push-pull drive component 5 and the first mounting base 33, which helps prevent energetic materials from entering and avoids the energetic materials from being squeezed and exploding when the push-pull drive component 5 pushes and pulls the clamping mechanism 3. It has good safety, and the corrugated sealing cover 61 can extend and retract with the movement of the clamping mechanism 3, so it will not hinder the movement of the clamping mechanism 3.

[0035] See details Figure 8 In this embodiment, a spring air pipe 62 is also connected between the bracket 1 and the first mounting base 33, and the spring air pipe 62 is located inside the corrugated sealing cover 61. The spring air pipe 62 can supply compressed gas to the clamping drive 35 and the jet nozzle 38, enabling the clamping drive 35 and the jet nozzle 38 to work, while preventing energetic materials from entering the interior and improving safety. The spring air pipe 62 can extend and retract with the movement of the clamping mechanism 3, so it will not hinder the movement of the clamping mechanism 3.

[0036] Furthermore, in this embodiment, the first mounting base 33 is provided with first guide rods 31 on both sides. The first guide rods 31 are arranged parallel to the push-pull drive component 5. The bracket 1 is provided with a first guide sleeve 11. The first guide rods 31 pass through the spring air tube 62 and the first guide sleeve 11. The first guide rods 31 cooperate with the first guide sleeve 11 to provide guidance for the reciprocating movement of the clamping mechanism 3, making the movement process more stable and smooth, and avoiding deviation. The first guide rods 31 pass through the spring air tube 62 to provide support for the flexible spring air tube 62 and the corrugated sealing cover 61 on the outside of the spring air tube 62, reducing the amount of sagging. This is especially suitable for working conditions where the stroke of the push-pull drive component 5 is long (in this embodiment, the stroke of the push-pull drive component 5 is about 3.2m long, and the length of the spring air tube 62 and the corrugated sealing cover 61 needs to be adapted to the stroke of the push-pull drive component 5).

[0037] See details Figure 1 In this embodiment, the first mounting base 33 has rollers 33 on both sides, and the bracket 1 has guide rails 12 on both sides, with the rollers 32 corresponding to the guide rails 12. The guide rails 12 cooperate with the rollers 32 to provide support and guidance for the clamping mechanism 3 when it is pushed out, thereby realizing two-stage guidance for the clamping mechanism 3 (the first guide rod 31 and the first guide sleeve 11 can also provide guidance), which helps to reduce the stress deformation of cantilever structural components (such as the first guide rod 31, the piston rod of the hydraulic cylinder, etc.) and further improves reliability. It should be noted that after the rollers 32 of the clamping mechanism 3 are disengaged from the guide rails 12, they can continue to roll along the carrier guide rails of the material carrier 2 (only the rollers at the bottom of the material carrier 2 are shown in the figure, and the corresponding carrier guide rails are not shown), thereby always providing support for the clamping mechanism 3, making the structure reasonable and reliable.

[0038] See details Figure 8 The guide rail 12 is disposed in the water tank 14, and the water tank 14 has a water-stopping component 15 that can float up and down at at least one end. By placing the guide rail 12 in the water tank 14, the water in the water tank 14 can wet and clean the guide rail 12 and the rollers 32 of the clamping mechanism 3, reducing static electricity and compression caused by friction. This can significantly reduce the risk of explosion when the clamping mechanism 3 moves along the guide rail 12, improve safety, facilitate automated transfer, and improve transfer efficiency. The water-stopping component 15 that can float up and down at at least one end of the water tank 14 allows the clamping mechanism 3 to move to or away from the guide rail 12 by lowering the water-stopping component 15, thereby reducing friction and compression between the clamping mechanism 3 and the water-stopping component 15 and reducing the risk of explosion. After the clamping mechanism 3 passes through, the water-stopping part 15 floats up (for example, a spring can be set below the water-stopping part 15 so that the water-stopping part 15 can float up automatically), reducing the water overflow in the water tank 14 and keeping the guide rail 12 submerged in the water. The structure is simple and has good reliability.

[0039] In a preferred embodiment, the clamping arm 34 is provided with a clamping groove 341, which facilitates the clamping arm 34 to clamp and fix the column 21 on the material carrier 2.

[0040] In a preferred embodiment, the clamping drive 35 is a double-rod cylinder, with the two piston rods of the double-rod cylinder connected one-to-one with the clamping arms 34 on both sides. Using a double-rod cylinder makes the clamping mechanism 3 more compact and occupies less space. Of course, in other embodiments, the clamping arms 34 on both sides can also be equipped with conventional cylinders. Compared to motors, cylinders are more suitable for energetic materials, avoiding the risk of explosion.

[0041] See details Figure 5 and Figure 7 In this embodiment, the positioning mechanism 4 includes a second mounting base 41, positioning posts 42 disposed on both sides of the second mounting base 41, and a positioning drive 43 for driving the second mounting base 41 to reciprocate. The positioning drive 43 is disposed on the bracket 1 and arranged parallel to the push-pull drive 5. After the hoisting mechanism 7 hoists the material carrier 2 into position, the positioning drive 43 pushes out the second mounting base 41 and the positioning posts 42 on both sides. The positioning posts 42 on both sides correct and position the hoisting mechanism 7, while preventing the hoisting mechanism 7 from moving when the clamping mechanism 3 moves the material carrier 2, thus ensuring high reliability. Preferably, the positioning drive 43 is also a cylinder. Compared with a motor, a cylinder is more suitable for energetic materials, avoiding explosions. Referring to the first mounting base 33, a corrugated sealing cover 61 is also connected between the second mounting base 41 and the bracket 1. The part where the positioning drive 43 connects to the second mounting base 41 is located inside the corrugated sealing cover 61, preventing energetic materials from entering.

[0042] Furthermore, in this embodiment, the second mounting base 41 is provided with a second guide rod 44, which is arranged parallel to both sides of the positioning drive member 43. The bracket 1 is provided with a second guide sleeve 13, and the second guide rod 44 passes through the second guide sleeve 13. The second guide rod 44 cooperates with the second guide sleeve 13 to provide guidance for the reciprocating movement of the second mounting base 41, making the movement process more stable and smooth, and avoiding deviation.

[0043] 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.
