Description

Technical Field

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

[0002] In chemical production processes, protective devices such as guardrails are used in areas such as reactor operating areas, high-pressure equipment areas, or hazardous chemical storage tank areas. The core function of guardrails is to form a safe buffer zone through physical isolation, effectively preventing personnel from accidentally entering hazardous work areas and blocking chemical splashes from accidental equipment leaks, thereby ensuring operational safety.

[0003] In use, the guardrail consists of multiple pieces, which are assembled together to form a barrier, preventing unauthorized personnel from entering the work area and ensuring work safety. While multiple guardrail pieces work together to achieve the desired protection, they require manual handling during use, which is time-consuming and labor-intensive. Therefore, current technology often installs casters at the base of the guardrail, facilitating its flexible movement.

[0004] In the aforementioned prior art, although installing casters at the bottom of the guardrail can facilitate transportation, the guardrail with casters is prone to displacement due to accidental collisions between personnel or equipment, or in strong winds; therefore, the guardrail with casters has insufficient stability. Utility Model Content

[0005] The purpose of this invention is to provide a chemical safety protection device that minimizes the problem of insufficient protection stability during the chemical safety protection process.

[0006] The aforementioned chemical safety protection device includes a guardrail body. The bottom of the base of the guardrail body has a slot, and a positioning block is installed in the slot. A pull rod is installed in the column of the guardrail body. The top of the base has a through hole that connects the top and bottom. One end of the pull rod passes through the through hole into the slot and connects to the positioning block, and the other end is provided with a locking block. A stopping component is provided on the column to stop the locking block above it. When the locking block is stopped, the positioning block is located in the slot.

[0007] Furthermore, the stop assembly includes a fixing block, which is fixed to the outer side wall of the column, and a limiting plate located below the locking block is hinged to the top of the fixing block.

[0008] Furthermore, a tension spring is provided between the fixing block and the limiting plate, and in the natural state of the tension spring, the limiting plate and the fixing block are attached together.

[0009] Furthermore, a handle is fixed to the top of the limiting plate.

[0010] Furthermore, the tie rod, positioning block, locking block, and stop assembly are provided in two sets, which are respectively installed between the two bases and the posts on the guardrail body.

[0011] Furthermore, the two levers form a "door" shaped structure.

[0012] Furthermore, the bottom of the positioning block is provided with an anti-slip pad.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention features a slot at the bottom of the base on the guardrail body, with a positioning block inside the slot. A pull rod is installed inside the upright of the guardrail body, and the pull rod is connected to the positioning block. Therefore, pushing the pull rod downwards moves the positioning block downwards, allowing it to contact the ground. This aligns the bottom of the positioning block and the caster wheel with the ground. The positioning block not only restricts the caster wheel's rotation but also increases the contact area with the ground, thus increasing friction and allowing the guardrail body to be placed more stably on the ground. This avoids the instability problem of wheeled guardrails in existing technologies that are prone to movement. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0024] Example

[0025] This embodiment describes a chemical safety protection device, such as... Figure 1 , Figure 6 and Figure 7 As shown, the guardrail includes a guardrail body 1, which is a known existing technology. The guardrail body 1 consists of casters 1.1, bases 1.2, posts 1.3, connecting rods 1.4, connecting rings 1.5, vertical bars 1.6, and horizontal bars 1.7. There are two posts 1.3 (left and right), and two bases 1.2 (left and right). The two posts 1.3 are fixed to the tops of the two bases 1.2 respectively. Each base 1.2 has four casters 1.1 installed at its bottom, arranged in a rectangular pattern. There are two horizontal bars 1.7, one above the other, fixed between the two posts 1.3. Several vertical bars 1.6 are fixed between the two horizontal bars 1.7. The connecting rod 1.4 is fixed to the outer wall of the left post 1.3, and the connecting ring 1.5 is fixed to the outer wall of the right post 1.3. This structure is a known existing structure and will not be described further. In use, as... Figure 7 In the middle of the position, prepare several guardrail bodies 1, insert the connecting rod 1.4 on one guardrail body 1 into the connecting ring 1.5 on another guardrail body 1, and the several guardrail bodies 1 can be connected together; when several guardrail bodies 1 are connected together, they can form a fence. In the chemical production process, the guardrail bodies 1 can effectively prevent personnel from accidentally entering the dangerous work area, thereby ensuring work safety.

[0026] like Figure 1 As shown, the bottom of the base 1.2 on the guardrail body 1 has a slot, and a positioning block 3 is installed in the slot. A pull rod 2 is installed in the post 1.3 on the guardrail body 1. The top of the base 1.2 has a through hole that runs vertically through the top and bottom. One end of the pull rod 2 passes through the through hole into the slot and connects with the positioning block 3, and the other end is equipped with a locking block 4. According to Figure 1The slot is located in the center of the bottom of the base 1.2, and the casters 1.1 are installed on the left and right sides of the bottom of the base 1.2. The column 1.3 has a hollow structure inside, so the pull rod 2 can be placed inside the column 1.3. After one end of the pull rod 2 is fixed to the positioning block 3, the other end of the pull rod 2 passes through the upper end of the column 1.3 and is located above the column 1.3. In use, by pulling the other end of the pull rod 2 up and down, the positioning block 3 can be moved up and down. When the positioning block 3 moves downward and contacts the ground, because the casters 1.1 are in contact with the ground, the positioning block 3 is in contact with the ground. Friction generated by surface contact restricts the normal rolling of the caster wheel 1.1. Therefore, when the guardrail body 1 is installed in the designated position, the design of the positioning block 3 moving downward to contact the ground increases the contact area between the guardrail body 1 and the ground, making the guardrail body 1 more stable on the ground. This avoids the problem of insufficient stability caused by only the caster wheel 1.1 contacting the ground. When it is necessary to move the guardrail body 1, the positioning block 3 can be moved upward by pulling the lever 2, which will move the positioning block 3 away from the ground. At this time, the caster wheel 1.1 can be used to move the design to the required location.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a fixing block 8 is provided on the column 1.3, and the fixing block 8 is fixed to the outer wall of the column 1.3. The top of the fixing block 8 is hinged to a limiting plate 5 located below the locking block 4; this section of the solution constitutes a stopping assembly for stopping the locking block 4 above the column 1.3. When the locking block 4 is stopped, the positioning block 3 is located in the slot; according to Figure 2 In the orientation, the right side wall of the fixing block 8 is fixed to the outer side wall near the top of the column 1.3, and the left side wall of the limiting plate 5 is hinged to the left side wall of the fixing block 8 by a hinge or pivot, so the limiting plate 5 can be flipped left and right.

[0028] At this point, because the limiting plate 5 is located below the locking block 4, the limiting plate 5 can restrict and block the locking block 4, preventing the locking block 4 from moving downwards; according to Figure 1In the orientation, when the locking block 4 is above the limiting plate 5, the bottom of the positioning block 3 is away from the ground, and the rest is located in the slot. Therefore, the positioning block 3 is located in the slot when the locking block 4 is in the stop state. When the positioning block 3 is in the slot, the guardrail body 1 can be pushed to the position of use by the universal wheel 1.1. After the guardrail body 1 is moved to the position of use, one operator can pull the lever 2 upward to move the locking block 4 upward. Since the limiting plate 5 and the fixing block 8 are hinged and can be flipped left and right, another operator can flip the limiting plate 5 to the left. After the limiting plate 5 is flipped to the left, the limiting plate 5 can be moved away from the bottom of the locking block 4, so it does not block the locking block 4. Then, the lever 2 is pushed downward to move the locking block 4 and the positioning block 3 downward. At this time, the positioning block 3 can contact the ground. When the positioning block 3 contacts the ground, it increases the friction between the guardrail body 1 and the ground. This limits the movement of the guardrail body 1 to a suitable position, preventing instability caused by the casters 1.1. When the guardrail body 1 needs to be moved, the lever 2 is pulled upwards, causing the positioning block 3 and the locking block 4 to move upwards. After the locking block 4 moves upwards, the limiting plate 5 is flipped back to below it, preventing downward movement. This limit also restricts the upward movement of the lever 2, which in turn limits the upward movement of the positioning block 3. Therefore, the positioning block 3 is positioned away from the ground. Once the positioning block 3 is away from the ground, it no longer restricts the casters 1.1, allowing the casters 1.1 to move the guardrail body 1.

[0029] During implementation, when the locking block 4 is located on the left outer wall of the pull rod 2, the stop assembly is located on the left column 1.3 of the pull rod 2; of course, the locking block 4 can also be located on the right outer wall of the pull rod 2. When the locking block 4 is located on the right outer wall of the pull rod 2, the stop assembly is located on the right column 1.3 of the pull rod 2.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a tension spring 7 is provided between the fixing block 8 and the limiting plate 5. In its natural state, the limiting plate 5 and the fixing block 8 are fitted together. When specifically installing the tension spring 7, it is preferable that grooves are provided on one side wall between the fixing block 8 and the limiting plate 5. One end of the tension spring 7 is fixed in the groove on the fixing block 8, and the other end is fixed in the groove on the limiting plate 5. In use, as... Figures 3-5In this position, the locking block 4 is located below the limiting plate 5, and the positioning block 3 can contact the ground. When it is necessary to move the guardrail body 1, the lever 2 needs to be pulled to move the positioning block 3 upward. After the positioning block 3 moves upward, it can avoid restricting the universal wheel 1.1. During the process of pulling the lever 2 upward, the locking block 4 will contact the bottom of the limiting plate 5. During the contact process, it continues to move upward, and the locking block 4 can push the limiting plate 5 open and flip it over. At this time, the tension spring 7 is pulled, that is, as Figure 5 As can be seen from the orientation, after the locking block 4 fully pushes open the limiting plate 5, the locking block 4 can move above the limiting plate 5 (i.e., as shown in the image). Figure 1 (in the middle position), at this time, the limit plate 5 that has been pushed open can be pulled back to the top of the fixing block 8 under the action of the tension spring 7. Therefore, the limit plate 5 can be pulled to the bottom of the locking block 4 to limit the locking block 4. Therefore, through the design of the tension spring 7, it is not necessary to manually flip the limit plate 5 to make it located at the bottom of the locking block 4, which makes operation easier.

[0031] like Figure 1 and Figure 3 As shown, a handle 6 is fixed to the top of the limiting plate 5; when it is necessary to remove the locking block 4 from... Figure 1 The orientation in the middle moves to Figure 3 When the position is in the middle, the lever 2 needs to be pulled upward first to move the limiting plate 5 away from the bottom of the locking block 4, so that the locking block 4 can move to the bottom of the limiting plate 5. When moving the limiting plate 5, the operating handle 6 can be used to more conveniently drive the limiting plate 5 to rotate and move, thus increasing the convenience of the operation process.

[0032] like Figure 1 As shown, there are two sets of tie rod 2, positioning block 3, locking block 4 and stop assembly. The two sets are respectively installed between the two bases 1.2 and the posts 1.3 on the guardrail body 1. The two sets are arranged symmetrically. The installation method and principle of the two sets are the same, so they will not be described in detail. Through the design of the two sets, positioning blocks 3 can be set at the bottom of the base 1.2. Therefore, the design of the two positioning blocks 3 can further increase the friction between the guardrail body 1 and the ground, and further improve the stability of the guardrail body 1 during use.

[0033] like Figure 1 As shown, the two pull rods 2 form a "door" shape; therefore, by connecting the two pull rods 2 together, when one of the pull rods 2 is pulled up or down, the two positioning blocks 3 can be moved down or up simultaneously, increasing the convenience during use; the height of the guardrail body 1 in this design can be selected from 1.05m to 1.2m, so by limiting the height, it is easy to move the positioning blocks 3 by holding the top position of the pull rod 2.

[0034] The bottom of the positioning block 3 is equipped with an anti-slip pad, which can be made of rubber or silicone. Therefore, the design of the anti-slip pad may increase the friction between the positioning block 3 and the ground, thereby further improving stability.

[0035] Workflow: First, move multiple guardrail panels 1 to the location where enclosure is needed, such as around high-voltage equipment; then... Figure 7 In the orientation of the guardrail body 1, several guardrail body sections 1 are connected together. Then, one worker pulls the lever 2 on one side of the guardrail body 1 to move it upward, which moves the locking block 4 upward away from the limiting plate 5. At this time, other workers (one or two) pull the two handles 6 on the other side of the guardrail body 1 to flip the limiting plate 5, so that the limiting plate 5 flips away from under the locking block 4. Then, the worker who pulled the lever 2 to move it upward releases the lever 2. At this time, because the limiting plate 5 has moved away from the bottom of the locking block 4, the locking block 4 on the lever 2 is no longer restricted by the limiting plate 5. Therefore, the locking block 4, the lever 2, and the positioning block 3 can move downward. During the downward movement, the positioning block 3 can contact the ground. Therefore, the positioning block 3 can restrict the free movement of the caster wheel 1.1. The rolling mechanism avoids the problem of insufficient protective stability of the guardrail body 1 caused by the existing omnidirectional wheel 1.1. When it is necessary to adjust the position of the guardrail body 1, the pull rod 2 is pulled upward, which drives the locking block 4 to move upward. During the upward movement of the locking block 4, the limiting plate 5 can be pushed open. After the locking block 4 pushes the limiting plate 5 open and moves above the limiting plate 5, the limited plate 5 returns to its original state under the action of the tension spring 7. Therefore, the limiting plate 5 can restrict the locking block 4 from moving downward. At this time, it can restrict the pull rod 2 and the positioning block 3 from moving downward. When the positioning block 3 can no longer move downward, the positioning block 3 will not affect the use of the omnidirectional wheel 1.1. It is then convenient to use the omnidirectional wheel 1.1 to drive the guardrail body 1 to move in order to adjust the position of the guardrail body 1.
