Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a chemical safety clamping device. Background Art

[0002] In the field of chemical safety, the transportation of chemical tanks is generally achieved through manual handling, which puts workers in a dangerous environment. In order to avoid this phenomenon, a clamping device is needed. By connecting the clamping device with the lifting equipment, the problem of manual handling can be replaced, thereby greatly improving the safety of workers during work.

[0003] The existing clamping device only relies on the extrusion force of the left and right clamping plates moving toward the middle to clamp the chemical barrel. This clamping method may lead to insufficient clamping friction when clamping chemical barrels with smooth surfaces, causing the chemical barrels to slip during transportation, making it difficult to ensure the stability of the clamping. In order to ensure stability, the only way is to increase the extrusion force toward the middle to make the clamping plates fit the chemical barrel more closely. This method may cause deformation and wear of the barrel body, which is not conducive to use.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a chemical safety clamping device is proposed. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1-4 As shown, a chemical safety clamping device includes a connecting rod 1, a clamping plate 2 is fixedly installed on the opposite side below the outer surface of the connecting rod 1, a suction cup 3 is installed on the opposite side of the outer surface of the clamping plate 2, the interior of the clamping plate 2 is set to be hollow, and an air hole is opened in the middle of the suction cup 3 to communicate with the interior of the clamping plate 2, an exhaust groove 4 is opened on the opposite side below the outer surface of the connecting rod 1, a cavity 5 is opened at the lower end of the inner surface of the connecting rod 1, an air pump 6 is fixedly installed on the inner surface of the cavity 5, and a connecting pipe 7 is fixedly installed on the end of the air pump 6 close to the clamping plate 2; the connecting rod 1 is set to an upright "Z" shape, the clamping plate 2 is set to a semi-arc shape, and the end of the connecting pipe 7 away from the air pump 6 passes through the connecting rod 1 and is communicated with the interior of the clamping plate 2.

[0024] By adopting the above technical solution, the connecting rod 1 can drive the clamping plate 2 to move in opposite directions to clamp the chemical barrel;

[0025] When the clamping plates 2 move towards each other to clamp the chemical barrel, the chemical barrel will squeeze the suction cup 3, so that the gas inside the suction cup 3 is discharged and it fits tightly to the surface of the chemical barrel, increasing the friction of clamping. The soft surface of the suction cup 3 can also prevent the clamping plates 2 from hard contact and squeezing with the barrel body, which may cause wear and deformation of the barrel body.

[0026] The air pump 6 extracts the internal gas of the clamping plate 2 through the connecting pipe 7, and then passes through the air holes of the suction cup 3, which can completely remove the internal air of the contact part between the suction cup 3 and the chemical barrel, thereby greatly increasing the adsorption of the suction cup 3 to the chemical barrel and improving the adsorption stability;

[0027] Furthermore, an assembly box 8 is provided above the connecting rod 1 , and movable plates 9 are slidably provided on the front and rear sides of the inner surface of the assembly box 8 .

[0028] By adopting the above technical solution, the movable plate 9 can move left and right on the front and back sides of the inner surface of the assembly box 8.

[0029] Furthermore, the movable plates 9 are arranged in a left-right distribution inside the assembly box 8, and gear blocks 10 are evenly distributed and fixedly installed on the surface of the opposite side of the movable plates 9; a drive motor 12 is fixedly installed in the middle of the upper part of the outer surface of the assembly box 8, and a gear column 11 is installed at the bottom output end of the drive motor 12 through the assembly box 8;

[0030] The gear column 11 is located inside the assembly box 8 , and the bottom end of the gear column 11 is rotatably connected to the lower middle portion of the inner surface of the assembly box 8 . The gear column 11 is meshed with the front and rear side gear blocks 10 .

[0031] By adopting the above technical solution, the driving motor 12 provides the gear column 11 with a rotating force. When the gear column 11 rotates, the gear block 10 is engaged, thereby driving the movable plate 9 to move.

[0032] Furthermore, a through cavity 13 is opened on the front and rear sides of the lower inner surface of the assembly box 8 below the movable plate 9, and the upper end of the connecting rod 1 slides through the through cavity 13 and is fixedly connected to the front and rear movable plates 9 away from the middle side.

[0033] By adopting the above technical solution, the movement of the movable plate 9 can drive the connecting rod 1 to move, thereby enabling the clamping plate 2 to complete the clamping work;

[0034] The through cavity 13 can limit the movable plate 9 through the connecting rod 1, thereby preventing the movable plate 9 from deflecting and ensuring that the connecting rod 1 can stably move left and right.

[0035] Furthermore, a "T"-shaped slider 14 is fixedly installed on the upper surface of the horizontal rod body of the connecting rod 1, and the upper surface of the horizontal rod body of the connecting rod 1 slides in contact with the lower surface of the assembly box 8, and the slider 14 is slidably arranged in a slide groove of the same shape as the slider 14 below the outer surface of the assembly box 8.

[0036] By adopting the above technical solution, the slider 14 utilizes the corresponding slide groove opened under the outer surface of the assembly box 8 to limit the movement of the connecting rod 1, thereby preventing the connecting rod 1 from tilting forward and backward, thereby preventing the movable plate 9 from tilting forward and backward, and preventing the movable plate 9 from being offset and stuck inside the assembly box 8.

[0037] Working principle: When using the chemical safety clamping device, first, the chemical barrel is located in the middle of the left and right clamping plates 2, and then the driving motor 12 drives the gear column 11 to rotate, and the tooth block 10 is engaged to make the front and rear movable plates 9 move synchronously in opposite directions, thereby driving the connecting rod 1 to move in opposite directions, so that the clamping plates 2 clamp the chemical barrel in opposite directions. When the movable plate 9 moves, the through cavity 13 limits the connecting rod 1, and the slider 14 uses the corresponding slide groove opened under the outer surface of the assembly box 8 to limit the movement of the connecting rod 1, thereby ensuring the stability of the engaged movement of the movable plate 9 and preventing the movable plate 9 from being offset and stuck inside the assembly box 8. 2 When the chemical barrel is clamped in opposite directions, the chemical barrel will squeeze the suction cup 3, so that the internal gas of the suction cup 3 is discharged and tightly fits the surface of the chemical barrel. The air pump 6 is used to extract the internal gas of the clamping plate 2 through the connecting pipe 7, so that the internal air of the contact part between the suction cup 3 and the chemical barrel can be completely extracted through the air holes of the suction cup 3, thereby increasing the adsorption of the suction cup 3 to the chemical barrel. The squeezing and clamping force of the clamping plate 2 itself, combined with the adsorption force of the suction cup 3, can greatly improve the stability of the clamping plate 2 on the chemical barrel, increase the clamping friction, and effectively prevent the chemical barrel from sliding and falling off during the clamping and transportation process. This is the working principle of the chemical safety clamping device.
