Description

Technical Field

[0001] This utility model relates to the field of methane chloride loading and unloading technology, specifically to a safety auxiliary device for methane chloride loading and unloading vehicles. Background Technology

[0002] Chlorinated methane is a product in which hydrogen atoms in methane molecules are replaced by chlorine atoms. It is an important chemical raw material and organic solvent, belonging to the bulk chlorine-based products. It can be prepared by direct chlorination of methane or methanol process, and is widely used in chemical and manufacturing industries, pharmaceuticals and pesticides, electronics and semiconductors.

[0003] Currently, chloromethane is stored and transported in oil drums. When loading and unloading these drums, forklifts and cranes are used to lift them from under the vehicle or load them into the vehicle using lifting clamps. However, in existing technologies, the lifting and moving of these drums by forklifts and cranes can cause them to shake, potentially leading to them falling off and releasing chloromethane vapors. This increases the pressure inside the drum and could cause an explosion. Therefore, a safety auxiliary device for loading and unloading chloromethane is proposed. This device uses a frame, chain, and lifting clamps to lift the drum containing chloromethane, and then uses a sleeve and support rod to hold the drum in place, preventing it from shaking during lifting and unloading. Utility Model Content

[0006] The structural base is provided with a protective component at the bottom between the shafts. The protective component includes a sleeve fixed to the bottom of the structural base by a flange. A first spring is provided at the top of the sleeve. A support rod is sleeved at the bottom of the sleeve. A pressure plate is fixed at the bottom of the support rod by a flange. A fixing component is provided on one side of the sleeve.

[0007] By adopting the above technical solution, the lifting clamps are hooked on both sides of the oil drum containing methane chloride, the frame is fixed to a forklift or lifting equipment, and the oil drum can be lifted by the chain. After the first spring pushes the support rod down and fixes it, the support rod and the sleeve support the lifted oil drum to prevent it from shaking.

[0008] Specifically, a lifting ring is provided at the top of the frame, a fixing bolt is connected to one end of the frame through a threaded groove, and a rubber pad is glued to the top inside the frame.

[0009] Specifically, the top of the support rod inside the sleeve is fixed to a limit block by bolts, and the bottom of the first spring is fixed to the top of the limit block by bolts.

[0010] Specifically, the support rod has equidistant locking holes on one side, and the pressure plate has an anti-slip pad glued to the bottom.

[0011] Specifically, the fixing assembly includes a cylinder that is fixed to one side of the sleeve by bolts, a pin rod that is sleeved through the inside of the cylinder, and a second spring that is sleeved inside the pin rod on the outside of the cylinder.

[0012] Specifically, a limiting ring is fixedly sleeved on the outer side of one end of the second spring, and one end of the pin is connected to a structural block through a threaded groove.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] After the oil drum containing chloromethane is lifted using a frame, chain, and clamps, it is then secured with a sleeve and support rod to prevent swaying during lifting, loading, and unloading. Figure 1-5 As shown, the safety auxiliary device for loading and unloading methane chloride trucks according to this utility model includes a frame 1, a structural seat 2 fixed to the bottom of the frame 1 by bolts, a shaft 201 rotatably connected to both ends inside the structural seat 2, a fixing ring 202 sleeved on the outside of the shaft 201, a chain 4 provided at the bottom of the fixing ring 202, and a lifting clamp 5 provided at the bottom end of the chain 4.

[0024] The structural base 2 is provided with a protective component 3 at the bottom between the shafts 201. The protective component 3 includes a sleeve 301 fixed to the bottom of the structural base 2 by a flange. A first spring 303 is provided at the top of the sleeve 301. A support rod 302 is sleeved at the bottom of the sleeve 301. A pressure plate 305 is fixed at the bottom of the support rod 302 by a flange. A fixing component 6 is provided on one side of the sleeve 301.

[0025] When in use, hook the lifting clamp 5 onto both sides of the oil drum containing methane chloride, fix the frame sleeve 1 to the forklift or lifting equipment, and the oil drum can be lifted by the chain 4. After the first spring 303 pushes the support rod 302 down and fixes it, the support rod 302 and the sleeve 301 support the lifted oil drum to prevent it from shaking.

[0026] For example, such as Figure 2 As shown, the present invention also includes a lifting ring 102 at the top of the frame sleeve 1, a fixing bolt 101 connected to one end of the frame sleeve 1 through a threaded groove, and a rubber pad 103 glued to the top of the inner side of the frame sleeve 1.

[0027] When in use, the lifting ring 102 makes it easy to hang the frame sleeve 1 on the lifting equipment, and tightening the fixing bolt 101 can fix the frame sleeve 1 on the forklift fork. The rubber pad 103 plays a role in preventing slippage.

[0028] For example, such as Figure 4 As shown, the present invention also includes a limit block 304 fixed to the top of the support rod 302 inside the sleeve 301 by bolts, and the bottom of the first spring 303 is fixed to the top of the limit block 304 by bolts.

[0029] In use, the first spring 303 pushes the support rod 302 downward through the limiting block 304, and the limiting block 304 can prevent the support rod 302 from falling out of the sleeve 301.

[0030] For example, such as Figure 4 As shown, the present invention also includes, on one side of the support rod 302, there are equidistant slots 307, and the bottom of the pressure plate 305 is glued with an anti-slip pad 306.

[0031] During use, the locking hole 307 facilitates the insertion of the pin 602, and the anti-slip pad 306 is used to prevent slippage between the pressure plate 305 and the oil drum.

[0032] For example, such as Figure 4 , Figure 5 As shown, the present invention also includes a fixing component 6, which includes a cylindrical body 601 fixed to one side of the sleeve 301 by bolts. A pin rod 602 is sleeved through the inside of the cylindrical body 601, and a second spring 603 is sleeved inside the pin rod 602 located outside the cylindrical body 601.

[0033] In use, the second spring 603 pushes the pin rod 602 to move, and the pin rod 602 is inserted into the locking hole 307 to fix the support rod 302 after it moves up and down.

[0034] For example, such as Figure 5 As shown, the present invention also includes a limiting ring 604 fixedly sleeved on the outer side of one end of the second spring 603, and a structural block 605 connected to one end of the pin rod 602 through a threaded groove.

[0035] When in use, the limiting ring 604 can prevent the pin rod 602 from falling out of the cylinder 601, and the pin rod 602 can be pushed and pulled by holding the structural block 605.

[0036] In use, personnel can place the frame sleeve 1 on the forklift fork and tighten the fixing bolts 101 to fix the frame sleeve 1 on the forklift fork and prevent it from falling off. Alternatively, the frame sleeve 1 can be suspended on the lifting equipment by the lifting rings 102. The lifting clamps 5 are hooked on both sides of the oil drum containing methane chloride. The forklift or lifting equipment can pull the lifting clamps 5 and the oil drum upward by the chain 4 to lift the oil drum containing methane chloride.

[0037] After the oil drum containing methane chloride is lifted, hold the structural block 605 and pull the pin rod 602 so that one end of it leaves the corresponding locking hole 307. The first spring 303 pushes the support rod 302 down through the limiting block 304 so that the pressure plate 305 presses on the oil drum.

[0038] When the structural block 605 is released, the second spring 603 pushes the pin rod 602 to move through the limiting ring 604, so that one end is inserted into the corresponding locking hole 307, which can fix the downward moving support rod 302. The support rod 302 and the sleeve 301 support the lifted oil drum, making it less likely to shake when it is lifted, loaded and unloaded.

[0039] The outer sides of the frame sleeve 1, sleeve 301, support rod 302, and chain 4 are all coated with protective paint to prevent corrosion and static electricity.
