Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, and in particular to a protective device for chemical safety production. Background Technology

[0002] Chemical safety protection devices are equipment or systems specifically designed to prevent, monitor and control potential hazards in chemical production processes. Protective devices are needed to protect containers containing chemical raw materials during the transfer of chemical raw materials.

[0003] A search of Chinese patent CN218808028U reveals a protective device for chemical safety production, comprising a buffer seat with a groove in its inner cavity. Weakening cylinders are fixedly connected to both sides of the inner wall of the groove. An air vent is provided on one side of the top of the inner cavity of each weakening cylinder. A pushing piston is movably connected to the inner cavity of the weakening cylinder, and a pushing column is fixedly connected to the inner side of the pushing piston. This protective device for chemical safety production achieves good protective effect by moving the buffer plate through the movement of the transport box. The movement of the buffer plate causes the buffer spring to compress and deform. Simultaneously, the movement of the transport box moves the moving seat, which in turn moves the pushing column. The movement of the pushing column then moves the pushing piston, and the movement of the moving seat further compresses and deforms the support spring. This achieves the advantage of good protective effect and solves the problem of poor protective effect in existing chemical safety material transport devices.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] Although the above-mentioned device can provide horizontal protection for containers containing chemical raw materials, if the container is subjected to vertical forces, the container will exert a force perpendicular to the installation direction of the locking screw, which can easily lead to damage to the locking screw and reduce the protective performance of the device. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a protective device for chemical safety production, which can support the container according to its direction of movement when it experiences bumps, thereby improving the protection of the container.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a protective device for chemical safety production, including a conveying seat, a placement seat, a positioning ring, and a container disposed inside the conveying seat. The placement seat is movably installed inside the lower part of the conveying seat, the positioning ring is disposed inside the upper part of the conveying seat, the container is movably installed inside the placement seat, a buffer mechanism is provided on the conveying seat, and a support mechanism is provided between the conveying seat and the placement seat.

[0008] Supporting institutions include:

[0009] Hydraulic chamber 1, support rod 1, and piston plate 1 are included. Hydraulic chamber 1 is embedded in the transport seat. Support rod 1 is movably installed on the top of hydraulic chamber 1 and passes through the top wall of hydraulic chamber 1 and is fixedly connected to the placement seat. Piston plate 1 is fixedly installed on the bottom of support rod 1.

[0010] Hydraulic chamber two, support rod two, and piston plate two are respectively embedded in the transport seat. Hydraulic chamber two is embedded in and movably installed inside hydraulic chamber two. Piston plate two is fixedly installed at the bottom of support rod two. Hydraulic pipes are fixedly installed between hydraulic chamber two and hydraulic chamber one.

[0011] Hydraulic chamber three, support rod three, and piston plate three are all fixedly installed on the bottom wall of the placement seat. Support rod three is embedded in the interior of hydraulic chamber three, and the bottom of support rod three is fixedly connected to the transport seat. Piston plate three is fixedly installed on support rod three and located inside hydraulic chamber three. A hydraulic groove is opened between hydraulic chamber one, transport seat, and support rod three, and the hydraulic groove penetrates the side walls of hydraulic chamber one and support rod three.

[0012] In some embodiments, the piston plate divides the interior of the hydraulic chamber into two parts, with hydraulic oil filling both the upper and lower parts of the hydraulic chamber.

[0013] In some embodiments, a return spring is sleeved on the second support rod, and the return spring is connected to the inner wall of the second piston plate and the second hydraulic chamber, respectively. The hydraulic pipe connects the interior of the second hydraulic chamber and the first hydraulic chamber.

[0014] In some embodiments, the buffer mechanism includes two sets of movable slots, movable blocks, movable rods, and buffer springs. The movable slots are formed on the side walls of the transport seat, and the movable blocks are movably installed inside the movable slots and fixedly connected to the positioning rings.

[0015] In some embodiments, the movable rod is fixedly installed on the top of the movable groove, the movable rod passes through the upper and lower walls of the movable block, and the buffer spring is fixedly sleeved on the movable rod and connected to the inner walls of the movable block and the movable groove respectively.

[0016] In some embodiments, the bottom of the transport seat is provided with casters for movement, and the positioning ring is fixedly sleeved on the side wall of the container by bolts.

[0017] Compared with existing technologies, the significant advantages of this invention are:

[0018] This invention, through the design of a support mechanism, allows the container to move. If bumps occur, the container generates an up-and-down force. When the container moves the placement seat downwards, support rod one moves downwards inside hydraulic chamber one, causing piston plate one to compress the hydraulic oil in the lower part of hydraulic chamber one. The compressed hydraulic oil then moves through hydraulic pipes to hydraulic chamber two. Once inside hydraulic chamber two, the hydraulic oil compresses piston plate two, causing it to move support rod two upwards. This upward movement of support rod two brings it into contact with the bottom wall of the placement seat, generating an upward force on the placement seat. The bottom is supported to counteract the downward force generated by the container due to bumps. When the container moves upward, the support rod and piston plate move upward inside the hydraulic chamber and squeeze the hydraulic oil. The hydraulic oil can then move into the hydraulic chamber three through the hydraulic groove. After entering the hydraulic chamber three, the hydraulic oil squeezes the piston plate three, causing the piston plate three to move upward. Since the support rod three is fixed to the transport seat, the hydraulic chamber three applies a downward force to the placement seat, thereby counteracting the upward force generated by the container due to bumps. This achieves the effect of supporting the container according to the direction of its movement when bumps occur, improving the protection of the container. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] This utility model provides an improved protective device for chemical safety production. The technical solution of this utility model is as follows:

[0027] like Figures 1 to 3 As shown, a safety protection device for chemical production includes a transport seat 1, a placement seat 2, a positioning ring 4, and a container 3 disposed inside the transport seat 1. The transport seat 1 is a hollow rectangular structure with casters for movement at its bottom. The placement seat 2 is a hollow cylindrical structure and is movably installed inside the lower part of the transport seat 1. The positioning ring 4 consists of two semi-circular rings and is disposed inside the upper part of the transport seat 1. The container 3 is used to store chemical materials and is movably installed inside the placement seat 2. The positioning ring 4 is fixedly sleeved on the side wall of the container 3 by bolts. A buffer mechanism is provided on the transport seat 1, and a support mechanism is provided between the transport seat 1 and the placement seat 2.

[0028] The support mechanism includes a hydraulic chamber 9, a support rod 10, a piston plate 11, a hydraulic chamber 2 12, a support rod 2 13, a piston plate 2 14, a return spring 15, a hydraulic chamber 3 17, a support rod 3 18, and a piston plate 3 19. The hydraulic chamber 9 is a hollow cylindrical structure, embedded in the transport seat 1. The support rod 10 is a cylindrical structure, movably mounted on the top of the hydraulic chamber 9 and passing through the top wall of the hydraulic chamber 9, and fixedly connected to the placement seat 2. The piston plate 11 is a circular plate with the same size as the interior of the hydraulic chamber 9, fixedly mounted on the bottom of the support rod 10. The piston plate 11 divides the interior of the hydraulic chamber 9 into two parts, both of which are filled with hydraulic oil. There are multiple hydraulic chambers 12, 13, 14, 15, 17, 18, and 19. Hydraulic chambers 12 are hollow cylindrical structures, and multiple hydraulic chambers 12 are respectively embedded in the transport seat 1. Support rods 13 are movably embedded inside hydraulic chambers 12. Piston plates 14 are circular plates of the same size as the inside of hydraulic chambers 12 and are fixedly installed at the bottom of support rods 13. Return springs 15 are movably sleeved on support rods 13 and connected to the inner walls of piston plates 14 and hydraulic chambers 12. Hydraulic pipes 16 are fixedly installed between multiple hydraulic chambers 12 and hydraulic chambers 19. The hydraulic pipes 16 are cylindrical tubes and connect to... Inside hydraulic chambers 2 (12) and 1 (9), hydraulic chamber 3 (17) is a hollow cylindrical structure. Multiple hydraulic chambers 3 (17) are fixedly installed on the bottom wall of the placement seat 2. Support rod 3 (18) is a cylindrical structure, embedded inside hydraulic chamber 3 (17), and its bottom is fixedly connected to the transport seat 1. Piston plate 3 (19) is a circular plate with the same size as the inside of hydraulic chamber 3 (17), fixedly installed on support rod 3 (18) and located inside hydraulic chamber 3 (17). A hydraulic groove 20 is provided between hydraulic chamber 1 (9), transport seat 1, and support rod 3 (18). The hydraulic groove 20 penetrates the side walls of hydraulic chamber 1 (9) and support rod 3 (18), allowing communication between the interiors of hydraulic chamber 1 (9) and hydraulic chamber 3 (17). The mechanism is designed so that when the transport seat 1 moves the container 3, if there is any bumping, the container 3 will generate an up-and-down force. When the container 3 moves the placement seat 2 downwards, the support rod 10 will move downwards inside the hydraulic chamber 9, and then drive the piston plate 11 to squeeze the hydraulic oil in the lower part of the hydraulic chamber 9. After being squeezed, the hydraulic oil will move through the hydraulic pipe 16 to the inside of the hydraulic chamber 12. When the hydraulic oil moves into the hydraulic chamber 12, it will squeeze the piston plate 14. After being squeezed, the piston plate 14 will drive the support rod 13 to move upwards. The upward movement of the support rod 13 will bring it into contact with the bottom wall of the placement seat 2, thereby generating an upward force to support the bottom of the placement seat 2.This counteracts the downward force generated by the bumps in container 3. When container 3 moves upward, the support rod 10, carrying the piston plate 11, moves upward inside the hydraulic chamber 9, compressing the hydraulic oil. The hydraulic oil then moves through the hydraulic groove 20 into the hydraulic chamber 17. Once inside the hydraulic chamber 17, the hydraulic oil compresses the piston plate 19, causing it to move upward. Since the support rod 18 is fixed to the transport seat 1, the hydraulic chamber 17 exerts a downward force on the placement seat 2, thus counteracting the upward force generated by the bumps in container 3.

[0029] The buffer mechanism includes two sets of movable slots 5, movable blocks 6, movable rods 7, and buffer springs 8. The movable slots 5 are rectangular slots located on both sides of the transport seat 1. The movable blocks 6 are rectangular blocks movably installed inside the movable slots 5 and fixedly connected to the positioning rings 4. The movable rods 7 are cylindrical structures fixedly installed at the top of the movable slots 5 and pass through the upper and lower walls of the movable blocks 6. The buffer springs 8 are fixedly sleeved on the movable rods 7 and connected to the inner walls of the movable blocks 6 and the movable slots 5, respectively. Through the buffer mechanism, the container 3 is only subjected to upward or downward forces. When the container 3 moves downward or upward, the positioning rings 4 drive the movable blocks 6 to move inside the movable slots 5. The movement of the movable blocks 6 can compress the buffer springs 8. After being compressed, the buffer springs 8 release a force opposite to that of the container 3, thereby buffering the movement of the container 3, reducing the travel distance of the container 3, and thus protecting the container 3.

[0030] The specific working method is as follows:

[0031] With the support mechanism in place, when the transport seat 1 moves the container 3, if there is any bumping, the container 3 will generate an up-and-down force. When the container 3 moves the placement seat 2 downwards, the support rod 10 will move downwards inside the hydraulic chamber 9, and then drive the piston plate 11 to squeeze the hydraulic oil at the bottom of the hydraulic chamber 9. After being squeezed, the hydraulic oil will move through the hydraulic pipe 16 to the inside of the hydraulic chamber 2. After the hydraulic oil moves into the hydraulic chamber 2, it will squeeze the piston plate 2. After being squeezed, the piston plate 2 will drive the support rod 2 13 to move upwards. The upward movement of the support rod 2 13 will then contact the bottom of the placement seat 2. The wall contact generates an upward force that supports the bottom of the placement seat 2, thus counteracting the downward force generated by the container 3 due to bumps. When the container 3 moves upward, the support rod 10, along with the piston plate 11, moves upward inside the hydraulic chamber 9 and squeezes the hydraulic oil. The hydraulic oil can then move through the hydraulic groove 20 to the inside of the hydraulic chamber 17. Once inside the hydraulic chamber 17, the hydraulic oil squeezes the piston plate 19, causing it to move upward. Since the support rod 18 is fixed to the transport seat 1, the hydraulic chamber 17 applies a downward force to the placement seat 2, thus counteracting the upward force generated by the container 3 due to bumps.

Matters not covered in this utility model are common knowledge to those skilled in the art.
