Technical Field

[0001] This utility model relates to the field of cone and hammer fall protection technology, specifically a cone and hammer fall protection device. Background Technology

[0002] Protective devices are equipment that prevents objects from being damaged, and that protect people or things from harm or danger. The detachment of cones and hammers refers to measures taken to prevent the accidental detachment of cone-shaped or hammer-shaped tools from their predetermined positions or connections during a specific project or operation. During inspection, cones and hammers need to be dropped from a 1-meter-high support, and protective devices are used to prevent them from falling to other positions when they detach.

[0003] The existing technical solution has the following drawbacks: When the cone and hammer fall-off protection device is used, the protection device is welded to the outside of the base plate for protection. Because the protection device is welded to the outside of the base plate, it is difficult to disassemble and replace the protection device. Therefore, we propose a cone and hammer fall-off protection device to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a cone and hammer fall-off protection device to solve the problem that the cone and hammer fall-off protection device mentioned in the background art is difficult to disassemble and replace because the protection device is welded to the outside of the base plate.

[0005] To achieve the above objectives, the present invention provides the following technical solution: As a preferred technical solution of the present invention, a cone and hammer fall-off protection device includes a base plate, an mounting plate installed on the middle side of its upper end, a bracket connected to the upper right side of the mounting plate, and a placement column connected to the upper left side of the mounting plate. Also includes: The first guardrail is set on the upper rear side of the base plate, and a movable structure is connected inside the base plate. The movable structure includes a blocking plate, a limiting block and a limiting rod. The blocking plate is installed inside the base plate, a limiting block is installed on the lower inner side of the blocking plate, and a limiting rod is connected to the middle outer side of the blocking plate. The second guardrail is installed on the upper front side of the base plate, and a fixing plate is installed on the middle rear side of the second guardrail. An installation structure is connected to the outer side of the fixing plate, and the installation structure includes a connecting plate, a spring and a moving rod. The connecting plate is installed on the outer side of the fixing plate, and a spring is provided on the outer front end of the connecting plate. A moving rod is connected through the middle of the spring.

[0006] Preferably, the upper front side of the first guardrail is further provided with a mounting connecting plate, and a connecting mounting block is fixedly installed on the lower outer side of the mounting connecting plate, and a connecting fixing rod is movably connected to the middle of the connecting mounting block.

[0007] Preferably, the fixing plate and the first guardrail are slidably connected.

[0008] Preferably, the blocking plate and the limiting block are fixedly connected, and the limiting block and the bottom plate are engaged.

[0009] Preferably, the blocking plate and the limiting rod are connected by a thread, and the vertical cross-section of the blocking plate is a "Z" shaped structure.

[0010] Preferably, the movable rod and the connecting plate are telescopically sliding connected, and the inner front end of the movable rod is inclined.

[0011] Preferably, the connecting mounting block and the first guardrail are connected by a snap-fit ​​connection, and the vertical cross-section between the connecting mounting block and the mounting connecting plate forms a "π" shaped structure.

[0012] Preferably, the connecting mounting block and the connecting fixing rod are connected by a thread, and the connecting fixing rod is symmetrically distributed about the center line of the mounting connecting plate.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: the cone and hammer fall-off protection device is provided with an installation structure that can limit the movement between guardrails, thereby playing an assembly role between guardrails, and is also provided with a movable structure that can move the blocking plate, thereby playing a limiting role for the guardrails. 1. By installing the second guardrail on the upper front side of the base plate, the second guardrail drives the fixing plate to engage with the front middle side of the first guardrail. Then, the connecting plate is installed on the middle front side of the first guardrail, and the connecting plate engages with the middle front side of the first guardrail. This allows the connecting plate to engage with the outside of the fixing plate, which in turn pushes the moving rod to slide outward. The spring drives the moving rod to slide inward, allowing the moving rod to engage with the rear outer side of the fixing plate. This facilitates limiting the movement between the first and second guardrails. 2. By installing the mounting connecting plate on the upper front side of the first guardrail, the mounting connecting plate drives the connecting fixing rod to engage with the upper front side of the first guardrail and the upper rear side of the second guardrail respectively. By rotating the connecting fixing rod, the connecting fixing rod is threaded on the upper outer side of the mounting connecting plate, thereby making the connecting fixing rod threaded in the middle of the connecting mounting block. This allows the connecting fixing rod to be threaded on the inner front side of the first guardrail and the inner rear side of the second guardrail respectively, facilitating further limiting the movement between the first and second guardrails. 3. By engaging the baffle plate on the upper outer side of the base plate, the baffle plate drives the limiting block to slide inward inside the base plate, thereby engaging the baffle plate on the outer side of the first guardrail and the outer side of the second guardrail. Rotating the limiting rod causes the limiting rod to be threaded on the outer side of the middle part of the baffle plate, thereby threading the limiting rod inside the base plate, which facilitates limiting the first and second guardrails, thus providing protection when the cone and hammer fall off.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1-7The present invention provides the following technical solution: A cone and hammer fall-off protection device includes: a base plate 1, a mounting plate 2, a placement column 3, a bracket 4, a first guardrail 5, a fixing plate 6, a mounting connecting plate 7, a blocking plate 8, a second guardrail 9, a limiting block 10, a limiting rod 11, a connecting plate 12, a spring 13, a moving rod 14, a connecting mounting block 15, and a connecting fixing rod 16. When using it for work, specifically such as Figure 1 , Figure 4 and Figure 5 As shown, a second guardrail 9 is installed at the front end of the first guardrail 5, a fixing plate 6 is fixedly installed at the middle of the rear end of the second guardrail 9, a connecting plate 12 is installed at the front middle of the first guardrail 5, a spring 13 is fixedly installed on the outer side of the front end of the connecting plate 12, and a moving rod 14 is connected through the middle of the spring 13. The first guardrail 5 is manually installed on the upper rear side of the base plate 1, and then the second guardrail 9 is manually installed on the upper front side of the base plate 1. This causes the second guardrail 9 to engage with the fixing plate 6 at the middle front end of the first guardrail 5. Then, the connecting plate 12 is installed on the front middle side of the first guardrail 5, causing the connecting plate 12 to slide forward on the outer side of the first guardrail 5. This causes the fixing plate 6 to push the moving rod 14 against the connecting plate 12. The front outer side of the first guardrail 5 slides outward, thereby causing the first guardrail 5 to push the moving rod 14 to slide outward on the front outer side of the connecting plate 12, so that the connecting plate 12 is engaged with the rear side of the fixed plate 6, thereby causing the connecting plate 12 to be engaged with the front side of the middle of the first guardrail 5, thereby causing the pushing force of the first guardrail 5 on the moving rod 14 to disappear, so that under the elastic action of the spring 13, the spring 13 drives the moving rod 14 to slide inward on the front outer side of the connecting plate 12, thereby causing the moving rod 14 to slide inward on the front of the first guardrail 5, thereby causing the moving rod 14 to be engaged with the rear outer side of the fixed plate 6, which facilitates the limiting of the first guardrail 5 and the second guardrail 9; Specific examples Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, mounting plates 7 are installed on the upper front side of the first guardrail 5 and the upper rear side of the second guardrail 9. A connecting mounting block 15 is fixedly installed on the lower outer side of the mounting plate 7. A connecting fixing rod 16 is movably connected inside the middle of the connecting mounting block 15. The mounting plate 7 is manually installed on the upper front side of the first guardrail 5, causing the connecting plate 7 to engage with the connecting fixing rod 16 on the upper front side of the first guardrail 5 and the upper rear side of the second guardrail 9 respectively. Then, the connecting fixing rod 16 is manually turned, causing it to be threaded onto the upper outer side of the mounting plate 7, thus connecting the connecting fixing rod 16 to the connecting mounting block 15. The middle part of 5 is threaded, and then the connecting fixing rod 16 and the connecting mounting block 15 are threaded together to make the connecting fixing rod 16 move downward under the action of the thread. This allows the connecting fixing rod 16 to be threaded together on the inner front side of the first guardrail 5 and the inner rear side of the second guardrail 9, which facilitates further limiting the distance between the first guardrail 5 and the second guardrail 9. Then, the mounting plate 2 is fixedly installed on the middle side of the upper end of the base plate 1. The placement column 3 is set on the left side of the upper end of the mounting plate 2, and the bracket 4 is set on the right side of the mounting plate 2. The object to be detected is placed on the upper outer side of the placement column 3, and then the cone and hammer are dropped from 1 meter away through the clamping structure set on the bracket 4 to detect the object. Specific examples Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a blocking plate 8 is movably connected to the outer side of the upper end of the base plate 1, a limiting block 10 is fixedly installed on the inner side of the lower end of the blocking plate 8, and a limiting rod 11 is movably connected to the outer side of the middle part of the blocking plate 8. The blocking plate 8 is manually placed on the outer side of the upper end of the base plate 1 and pushed inward, so that the blocking plate 8 slides inward on the inner side of the base plate 1 under the action of the thrust. This causes the blocking plate 8 to drive the limiting block 10 to slide inward inside the base plate 1, and then the blocking plate 8 slides inward until it engages with the first guardrail 5 and the second guardrail 9 respectively. Then the limiting rod 11 is manually turned so that the limiting rod 11 is threadedly connected to the outer side of the middle part of the blocking plate 8, so that the limiting rod 11 moves downward and is threadedly connected inside the base plate 1. This facilitates the limiting of the first guardrail 5 and the second guardrail 9, thus playing a protective role when the cone and hammer fall off.
