Description

Technical Field

[0001] This utility model belongs to the technical field of safety protection devices, and in particular relates to a safety protection device for openings in production sites. Background Technology

[0002] Openings in the production site refer to openings that exist in the project itself or are required by the process during production. These openings may cause people and materials to fall, and the fall height is usually greater than or equal to 2 meters, posing a potential threat to the safety of on-site workers.

[0003] In production sites, these openings must be effectively protected to prevent people or objects from falling in, which requires the use of safety protection devices. Existing safety protection devices often place guardrails around the openings, and to prevent the guardrails from swaying, adjacent guardrails need to be spliced ​​together. The existing splicing method is cumbersome, time-consuming and labor-intensive, and cannot quickly block the openings, so the effect is not good enough. The problem with the above technology is that adjacent guardrails cannot be spliced ​​or removed quickly, and the openings cannot be blocked quickly. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a safety protection device for openings in production sites that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a safety protection device for openings in a production site includes a protective component and a blocking component. The protective component includes two fixed frames, a guardrail, multiple connecting posts, and reflective stickers. The opposite ends of the two fixed frames are respectively attached to the left and right sides of the guardrail. The multiple connecting posts are fixed inside the guardrail and are evenly distributed. The rear side of the reflective sticker is fixedly connected to the bottom of the front side of the guardrail. The blocking component is located at the bottom of the rear side of the guardrail. The blocking component includes a blocking plate, a rotating block, and a support block. The front side of the support block is fixedly connected to the bottom of the rear side of the guardrail. The surface of the rotating block is movably connected to the interior of the support block. The bottom of the rotating block is fixedly connected to the front side of the top of the blocking plate. The bottom of the blocking plate is attached to the ground. Protrusions are fixedly connected to both sides of the guardrail. The left protrusion has a cavity inside. The cavity contains a positioning component and a moving component. The surfaces of the two protrusions are respectively inserted into and attached to the interiors of the two fixed frames.

[0006] The protective components are used to prevent workers from coming into contact with the opening;

[0007] The blocking component is used to block the opening.

[0008] To secure the guardrail to the mounting bracket, the positioning assembly preferably includes a positioning block, a return spring, a rotating rod, and a mating block. The surface of the positioning block is movably connected to the interior of the cavity. The right side of the positioning block is fixedly connected to the left side of the return spring. The right side of the return spring is fixedly connected to the bottom right side of the cavity's inner wall. The right side of the rotating rod is abutted against the top left side of the positioning block. The bottom inside the rotating rod is movably connected to the surface of the mating block. The left side of the mating block is connected to the bottom left side of the cavity's inner wall. Through the positioning assembly, the left side of the positioning block can sequentially penetrate the protrusion and the mounting bracket, extending into the interior of the mounting bracket. The return spring provides both fixing and rebound functions. The positioning block, through the return spring, secures the guardrail to the mounting bracket.

[0009] To allow the guardrail to be separated from the fixing frame, preferably, the movable component includes a push rod, a sliding block, and a tension spring. The surfaces of the push rod and the sliding block are movably connected to the interior of the cavity. The bottom of the push rod is fixedly connected to the top of the sliding block. The bottom of the tension spring is fixedly connected to the left side of the top of the sliding block. The top of the tension spring is fixedly connected to the top of the inner wall of the cavity. The bottom of the sliding block is in contact with the top of the rotating rod surface. By using the movable component, the positioning block can be moved out of the interior of the fixing frame, thereby allowing the guardrail to disengage from the fixing frame. The tension spring provides a rebound effect, allowing the push rod and the sliding block to automatically return to their original positions after movement.

[0010] To improve the movement effect of the positioning block, preferably, a control block is fixedly connected to the bottom of the positioning block, and two U-shaped blocks are slidably connected to the surface of the control block. The bottom of the two U-shaped blocks is fixedly connected to the bottom of the inner wall of the cavity. The control block and the two U-shaped blocks play a limiting role, so that the control block and the two U-shaped blocks can only move to the left or right, thereby improving the use effect.

[0011] To limit the movement range of the sliding block and the push rod, preferably, a limiting block is fixedly connected to the left side of the sliding block, and a limiting rod is slidably connected inside the limiting block. The top of the limiting rod is fixedly connected to the left side of the top of the cavity inner wall. Through the limiting block and the limiting rod, the sliding block and the push rod can only move vertically upward or downward, thus playing a limiting role.

[0012] In order to fix the blocking plate after it is rotated upward, preferably, mounting blocks are fixedly connected to both sides of the rotating block. Both mounting blocks can be fixedly connected to the bottom of the rear side of the guardrail by bolts. When the guardrail is removed or moved, the blocking plate drives the rotating block to rotate upward and the two mounting blocks rotate. Then, the two mounting blocks are fixed to the guardrail by bolts to fix the blocking plate.

[0013] To improve the connection between the guardrail and the fixing frame, preferably, L-shaped blocks are fixedly connected to the top and bottom of both sides of the guardrail. The surfaces of the multiple L-shaped blocks are respectively inserted into the top and bottom of the front side of the two fixing frames.

[0024] like Figures 1 to 5As shown in the figure, this utility model provides a safety protection device for openings in production sites, including a protective component 1 and a blocking component 2. The protective component 1 includes two fixing frames 101, a guardrail 102, multiple connecting posts 103, and reflective stickers 104. The opposite ends of the two fixing frames 101 are respectively attached to the left and right sides of the guardrail 102.

The rear side of the reflective stickers 104 is fixedly connected to the bottom of the front side of the guardrail 102. The blocking component 2 is disposed at the bottom of the rear side of the guardrail 102. The blocking component 2 includes a blocking plate 201, a rotating block 202, and a support block 203. The front side of the support block 203 is fixedly connected to the bottom of the rear side of the guardrail 102. The surface of the rotating block 202 is movably connected to the interior of the support block 203. The bottom of the rotating block 202 is fixedly connected to the front side of the top of the blocking plate 201. The bottom of the blocking plate 201 is in contact with the ground. Protrusions 3 are fixedly connected to both the left and right sides of the guardrail 102. A cavity 4 is opened inside the left protrusion 3. A positioning component 5 and a moving component 6 are arranged inside the cavity 4. The surfaces of the two protrusions 3 are respectively inserted and connected to the interior of the two fixing frames 101 and fit together. The protective component 1 is used to prevent workers from contacting the opening. The blocking component 2 is used to block the opening. In order to fix the guardrail 102 to the fixing frame 101, the positioning component 5 includes a positioning block 501, a return spring 502, a rotating rod 503 and a mating block 504. The surface of 501 is movably connected to the interior of cavity 4. The right side of positioning block 501 is fixedly connected to the left side of return spring 502. The right side of return spring 502 is fixedly connected to the bottom right side of the inner wall of cavity 4. The right side of rotating rod 503 is in contact with the top left side of positioning block 501. The bottom inside of rotating rod 503 is movably connected to the surface of mating block 504. The left side of mating block 504 is connected to the bottom left side of the inner wall of cavity 4. Through positioning assembly 5, the left side of positioning block 501 can sequentially pass through protrusion 3 and fixing frame 101 and extend into the interior of fixing frame 101. Return spring 502 plays a fixing and rebounding role. Positioning block 501 fixes guardrail 102 to fixing frame 101 through return spring 502. In order to make guardrail 102 Separated from the fixed frame 101, the movable component 6 includes a push rod 601, a sliding block 602, and a tension spring 603. The surfaces of the push rod 601 and the sliding block 602 are movably connected to the interior of the cavity 4. The bottom of the push rod 601 is fixedly connected to the top of the sliding block 602. The bottom of the tension spring 603 is fixedly connected to the left side of the top of the sliding block 602. The top of the tension spring 603 is fixedly connected to the top of the inner wall of the cavity 4. The bottom of the sliding block 602 is in contact with the top surface of the rotating rod 503. By using the movable component 6, the positioning block 501 can be moved out of the fixed frame 101, thereby disengaging the guardrail 102 from the fixed frame 101. The tension spring 603 provides a springback function, allowing the push rod 601 and the sliding block 602 to automatically return to their original positions after movement.To improve the movement of the positioning block 501, a control block 7 is fixedly connected to the bottom of the positioning block 501. Two U-shaped blocks 8 are slidably connected to the surface of the control block 7. The bottoms of the two U-shaped blocks 8 are fixedly connected to the bottom of the inner wall of the cavity 4. The control block 7 and the two U-shaped blocks 8 serve as limiters, allowing the control block 7 and the two U-shaped blocks 8 to move only to the left or right, thus improving the usability. To limit the movement range of the sliding block 602 and the push rod 601, a limiting block 9 is fixedly connected to the left side of the sliding block 602. A limiting rod 10 is slidably connected inside the limiting block 9. The top of the limiting rod 10 is fixedly connected to the left side of the top of the inner wall of the cavity 4. The limiting block 9 and the limiting rod 10 allow the sliding block 602 and the push rod 601 to move only vertically upwards or downwards, thus serving as limiters. To allow the blocking plate 201 to rotate upwards and then be fixed, two U-shaped blocks 8 are fixedly connected to both sides of the rotating block 202. Mounting blocks 11, both of which can be fixedly connected to the bottom rear side of the guardrail 102 by bolts. When the guardrail 102 is removed or moved, the blocking plate 201 drives the rotating block 202 to rotate upwards, causing the two mounting blocks 11 to rotate as well. The two mounting blocks 11 are then fixed to the guardrail 102 by bolts, thus securing the blocking plate 201. To improve the connection between the guardrail 102 and the fixing frame 101, L-shaped blocks 12 are fixedly connected to the top and bottom of both sides of the guardrail 102. The surfaces of the multiple L-shaped blocks 12 are respectively inserted into the top and bottom of the front side of the two fixing frames 101. After the multiple L-shaped blocks 12 are inserted into the interior of the two fixing frames 101, the multiple L-shaped blocks 12 move vertically downwards with the weight of the guardrail 102, thereby stabilizing the connection between the guardrail 102 and the fixing frame 101.

[0025] The working principle of this utility model:

[0026] When the guardrail 102 needs to be removed, by pressing down and moving the sliding block 602 downwards, the sliding block 602 will press the rotating rod 503 downwards. The rotating rod 503 will press the positioning block 501 and move it to the right, causing the positioning block 501 to move out of the inside of the fixing frame 101. At this time, the guardrail 102 can be moved upwards. The movement of the guardrail 102 will cause the L-shaped block 12 and the protrusion 3 to move upwards inside the fixing frame 101. Then, the guardrail 102 is moved forward, thereby disengaging from the fixing frame 101. The blocking plate 201 is then rotated upwards by the rotating block 202 and the support block 203. The rotating block 202 will drive the mounting block 11 to rotate, and then the mounting block 11 will be fixed to the guardrail 102 by bolts, thus removing the guardrail 102. When protection of the opening is required, first fix the bottom of the fixing frame 101 to the ground with bolts, remove the bolts fixing the mounting block 11 to the guardrail 102, rotate the blocking plate 201 downwards, and insert the guardrail 102, along with the L-shaped block 12 and the protrusion 3, into the interior of the fixing frame 101. Then, let the guardrail 102 fall down. The movement of the sliding block 602 will cause the tension spring 603 to deform. Release the lever 601, and the sliding block 602 will cause the lever 601 to spring back to its original position through the tension spring 603. The movement of the positioning block 501 will cause the return spring 502 to deform. At the same time as releasing the lever 601, the positioning block 501 will spring back to the interior of the fixing frame 101 through the return spring 502, and the rotating rod 503 will spring back to its original position, thus fixing the guardrail 102 to the fixing frame 101.
