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

[0016] This utility model discloses a lifting device for flammable and explosive materials. The object to be lifted moves along a movable guide into a bracket. The movable guide is located in a water tank. The water in the tank cleans and lubricates the movable guide, reducing dust adhesion and keeping it moist, which helps reduce friction between the movable guide and the object being lifted, significantly reducing the explosion risk of energetic solid materials. At least one end of the water tank is equipped with a water-stopping component that can float up and down. When the object needs to move to or away from the movable guide, it can be squeezed to make the water-stopping component sink, thus allowing it to pass smoothly.

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 8 This illustration shows an embodiment of the lifting device for flammable and explosive materials according to the present invention. The lifting device for flammable and explosive materials in this embodiment includes a support 1 and a bracket 2. The support 1 is provided with a lifting drive component 3 for driving the bracket 2 to rise and fall. The bracket 2 is provided with a moving guide component 21 and a positioning component 22 for preventing the object to be lifted from moving along the moving guide component 21. The moving guide component 21 is disposed in a water tank 24, and at least one end of the water tank 24 is provided with a water-stop component 25 that can float up and down. See details. Figure 5 and Figure 7 The movable guide 21 can be a guide rail, guide column, etc. When the object being lifted enters from one end of the water tank 24 and exits from the other end, water-stopping components 25 need to be installed at both ends of the water tank 24. However, when the object being lifted enters and exits from the same end of the water tank 24, water-stopping components 25 can be installed at only one end of the water tank 24. 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, etc. Springs or other components can be installed below the water-stopping component 25 to achieve up-and-down floating, resulting in a simple and reliable structure.

[0033] In this embodiment, the lifting device for flammable and explosive materials moves the object being lifted along the moving guide 21 into the bracket 2. The moving guide 21 is located in a water tank 24. The water in the water tank 24 cleans and lubricates the moving guide 21, reducing dust adhesion to it and keeping it moist, which helps reduce friction between the object being lifted and significantly reduces the explosion risk of energetic solid materials. At least one end of the water tank 24 is equipped with a water-stopping element 25 that can float up and down. When the object being lifted needs to move to or leave the moving guide 21, it can be pushed down by the water-stopping element 25, allowing it to pass smoothly and reducing friction and pressure between the object being lifted and the water-stopping element 25, thus significantly reducing the explosion risk of energetic materials. After the object being lifted passes, the water-stopping element 25 floats up, reducing water overflow from the water tank 24 and keeping the moving guide 21 submerged in water. After the object to be lifted is positioned on the bracket 2, the positioning component 22 positions the object to prevent it from moving accidentally during lifting. Finally, the lifting drive component 3 drives the bracket 2, the object to be lifted, and other components to lift as a whole. The structure is simple, highly automated, and reliable, which helps to reduce labor intensity and improve efficiency.

[0034] See details Figure 2 and Figure 3 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 moving guide 21. When the object to be lifted needs to move along the moving guide 21, the piston rods of the first positioning cylinder 221 and the second positioning cylinder 222 retract to avoid obstruction. After the object 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 moving guide 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.

[0035] In a preferred embodiment, both the first positioning cylinder 221 and the second positioning cylinder 222 are arranged vertically. The bracket 1 is equipped with a first limit switch 11 and a second limit switch 12, with the first limit switch 11 located on one side of the first positioning cylinder 221 and the second limit switch 12 located on one side of the second positioning cylinder 222. The vertical arrangement of the first positioning cylinder 221 and the second positioning cylinder 222 fully utilizes the vertical space of the bracket 2. In other embodiments, the first positioning cylinder 221 and the second positioning cylinder 222 can also be arranged horizontally on the side of the moving guide 21, but this would increase the width of the bracket 2. The first limit switch 11 can limit the lowest position of the piston rods of the first positioning cylinder 221 and the second positioning cylinder 222, while the second limit switch 12 limits the highest position of the piston rods of the first positioning cylinder 221 and the second positioning cylinder 222, further improving reliability. Of course, the first limit switch 11 and the second limit switch 12 can also be interchanged. Compared to electric motors, the first positioning cylinder 221 and the second positioning cylinder 222 are more suitable for use with energetic materials to avoid explosions.

[0036] See details Figure 3 , Figure 4 and Figure 8 In this embodiment, a lifting guide assembly 4 is provided between the bracket 1 and the support 2. The lifting guide assembly 4 provides guidance for the lifting movement of the support 2, making the lifting process more stable and smooth, and preventing deviation.

[0037] Furthermore, in this embodiment, the lifting guide assembly 4 includes lifting guide members 41 disposed on both sides of the lifting drive member 3 and guide sleeves 42 disposed on the bracket 2, with the guide sleeves 42 sleeved around the outer periphery of the lifting guide members 41. Preferably, the lifting guide members 41 are guide posts, which, in conjunction with the guide sleeves 42, provide good guidance, making the lifting process smoother and more stable, and preventing deviation. Of course, in other embodiments, the lifting guide members 41 can also be guide rails, slides, etc., and the guide sleeves 42 can also be rollers, sliders, etc., which will not be elaborated further.

[0038] Furthermore, in this embodiment, an oil-free bushing (not shown in the figure) is provided inside the guide sleeve 42. Providing an oil-free bushing between the guide sleeve 42 and the lifting guide member 41 can further improve the motion accuracy, reduce frictional resistance, and lower the risk of explosion.

[0039] Furthermore, in this embodiment, the bracket 2 is provided with a first sealing seat 23, and the support 1 is provided with a second sealing seat 13. The second sealing seat 13 is located above the first sealing seat 23. A corrugated sealing cover 51 is connected between the second sealing seat 13 and the first sealing seat 23. The guide sleeve 42 is located inside the corrugated sealing cover 51. A corrugated sealing tube 52 is provided on the outer periphery of the lifting guide 41. The lower end of the corrugated sealing tube 52 is connected to the support 1, and the upper end of the corrugated sealing tube 52 is connected to the first sealing seat 23. See details. Figure 4 The corrugated sealing cover 51 and the corrugated sealing tube 52 can form closed spaces on the upper and lower sides of the guide sleeve 42 respectively, preventing entry into the gap between the guide sleeve 42 and the lifting guide 41, thereby preventing the explosion of energetic materials when subjected to friction and compression, and further improving safety. Correspondingly, the connection between the lifting drive 3 and the first sealing seat 23 is also located inside the corrugated sealing cover 51, and the corrugated sealing cover 51 and the corrugated sealing tube 52 can extend and retract without hindering the lifting movement of the bracket 2. The structure is reasonable and effective.

[0040] See details Figure 6 and Figure 8 In this embodiment, the bracket 1 is provided with a first adjusting plate 14, and a second adjusting plate 15 is provided on the first adjusting plate 14. The first adjusting plate 14 is provided with a first waist-shaped adjusting hole 141, and the second adjusting plate 15 is provided with a second waist-shaped adjusting hole 151. The second waist-shaped adjusting hole 151 is arranged perpendicularly to the first waist-shaped adjusting hole 141. The lifting guide 41 is provided on the second adjusting plate 15. The position of the lifting guide 41 can be adjusted in four directions (front, back, left, and right) by the first adjusting plate 14 and the second adjusting plate 15, thereby compensating for manufacturing errors, keeping the lifting guides 41 on both sides parallel, ensuring the accuracy of the lifting movement of the bracket 2, reducing friction, and further improving safety.

[0041] Furthermore, in this embodiment, the second adjusting plate 15 is provided with a spherical washer 16 for installing the lifting guide 41, which facilitates small-range adjustment of the installation angle of the lifting guide 41, thereby compensating for manufacturing errors, keeping the lifting guides 41 on both sides parallel, ensuring the accuracy of the lifting movement of the bracket 2, reducing friction, further improving safety, and the structure is simple and effective.

[0042] In a preferred embodiment, the lifting drive component 3 is a hydraulic cylinder, which integrates a hydraulic lock and a throttle valve 31. Compared to an electric motor, a hydraulic cylinder is more suitable for handling energetic materials, preventing explosions. The integration of a hydraulic lock and throttle valve 31 into the hydraulic cylinder helps prevent oil leakage at the hydraulic cylinder joint or rupture of the oil pipe, thus preventing the bracket 2 from falling and further enhancing safety.

[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.
