Description

Technical Field

[0001] This utility model relates to the field of protective device technology, specifically to a personnel protective device for blasting sites that is easy to deploy. Background Technology

[0002] Blasting is a technique that utilizes the compression, loosening, destruction, throwing, and killing effects produced by the explosion of explosives in air, water, soil, rock, or objects to achieve a desired purpose. It is mainly used in earthwork engineering and the demolition of metal buildings and structures. At blasting sites, appropriate protective devices are usually used to avoid injury to workers from flying rocks.

[0003] For example, a blasting site safety protection device, such as the one described in announcement number CN222211437U, involves inserting a ground-mounted rod into the soil, at which point a fixing block contacts the ground and is secured with screws. Then, a mounting plate is placed between connecting plates on another set of protective structures and secured with screws, thus completing the splicing of multiple protective structures. Simultaneously, an extension frame moves upward, at which point a slider slides to the inner top wall of the chute and its position is fixed with bolts. The extension frame, protective plate, and protective plate effectively increase the protective area. However, the aforementioned prior art has the following technical problems:

[0004] Existing protective devices are easy to insert into the soil using ground stakes at their bottom. However, these ground stakes are always exposed, which can easily cause injury to workers when they move the protective devices. In addition, the protective devices are heavy and usually need to be moved manually, which can lead to low deployment efficiency.

[0005] Therefore, we propose an easily deployable personnel protection device for blasting sites to address the problems mentioned above. Summary of the Invention

[0006] The purpose of this utility model is to provide a personnel protection device for blasting sites that is easy to deploy, in order to solve the problem mentioned in the background art that the existing protective devices on the market are easy to insert into the soil through the ground pin at the bottom. However, the ground pin is always exposed. When workers carry the protective device, the exposed ground pin can easily cause injury to the workers. At the same time, the protective device itself is heavy and usually needs to be carried manually, which can easily lead to low deployment efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a personnel protection device for blasting sites that is easy to deploy, comprising a protective base plate, a snap-fit ​​seat installed on one side of the protective base plate, and a plug-in block adapted to the snap-fit ​​seat installed on the other side of the snap-fit ​​seat, both the snap-fit ​​seat and the plug-in block having positioning holes, a guide rod being installed through the bottom of the protective base plate, and an adjusting block being connected to the guide rod, a universal guide wheel being installed at the lower end of the adjusting block, and a grounding pin being installed at the upper end of the adjusting block, and a locking nut being connected to one end of the guide rod extending out of the protective base plate.

[0008] Preferably, the outer wall of the plug block and the inner wall of the snap-fit ​​seat are in contact with each other, and the cross-section of the snap-fit ​​seat is set as a "U" shaped structure.

[0009] By adopting the above technical solution, the outer wall of the plug block and the inner wall of the card socket fit together, thereby ensuring the stability of the plug block in the card socket.

[0010] Preferably, the guide rod is rotatable on the protective substrate, and the surface of the end of the guide rod extending out of the protective substrate is provided with threads.

[0011] By adopting the above technical solution, the rotation of the guide rod on the protective base plate can drive the adjustment block on it to rotate synchronously, and the rotation of the adjustment block can be used to exchange the positions of the universal guide wheel and the grounding pin.

[0012] Preferably, the threaded section of the guide rod extending out of the protective substrate is threadedly connected to the locking nut, and the side of the locking nut facing the protective substrate is set as a rough surface.

[0013] By adopting the above technical solution, the locking nut can be made to come into contact with the protective base plate by rotating on the guide rod.

[0014] Preferably, the positioning holes on the plug block and the positioning holes on the snap-fit ​​socket correspond one-to-one.

[0015] By adopting the above technical solution, the positioning holes on the plug-in block and the snap-fit ​​base correspond one-to-one, which facilitates the subsequent fixing of the two with bolts.

[0016] Preferably, the protective substrate has a buffer side plate on its side, and the buffer side plate is connected to the protective substrate by an auxiliary spring.

[0017] By adopting the above technical solution, when the buffer side plate is hit by gravel, the elastic deformation of the auxiliary spring can play a buffering role.

[0018] Preferably, the upper end of the buffer side plate extends outward to form an inclined bend, and multiple auxiliary springs are evenly distributed between the buffer side plate and the protective base plate.

[0019] By adopting the above technical solution, the inclined bending part can be set to facilitate the protection of debris passing overhead, and the inclined structure of the bending part can make the falling debris slide down.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the personnel protection device for blasting sites that is easy to deploy has adjustable casters at the bottom of the device, which make it easy to push the device during transport and to fix it in place using pins during deployment.

[0021] 1. It is equipped with plug-in blocks and snap-fit ​​seats. The plug-in blocks and snap-fit ​​seats on the left and right sides of the protective substrate facilitate the plug-in assembly between adjacent protective substrates. At the same time, the positioning holes on the plug-in blocks and snap-fit ​​seats correspond one-to-one, which facilitates the subsequent fixing of adjacent assembled protective substrates with bolts.

[0022] 2. Equipped with universal guide wheels, the universal guide wheels at the bottom of the adjustment block facilitate the movement of the protective substrate during transport. At the same time, the grounding pin is located above the adjustment block, thus preventing the grounding pin from being exposed and causing injury to workers during the transport of the protective substrate. Therefore, the movement of the protective substrate can improve the transport speed of the protective substrate and the deployment speed of the protective device.

[0023] 3. A buffer side plate is provided. When the debris generated during the blasting process comes into contact with the buffer side plate, the buffer side plate can move, and the auxiliary spring between the buffer side plate and the protective base plate will undergo elastic deformation. The elastic deformation of the auxiliary spring can play a buffering role. At the same time, the upper end of the buffer side plate is provided with an inclined bending part, which can block the debris falling from the top, and the inclined bending part can guide the falling debris to slide down.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1: Please refer to Figures 1-6 Existing protective devices are easily inserted into the soil using ground-mounted pins at their bottom. However, these pins remain exposed, posing a risk of injury to workers during transport. Furthermore, the protective devices are heavy and typically require manual handling, leading to inefficient deployment. To address this issue, this embodiment discloses a personnel protective device for blasting sites that facilitates deployment. The device includes a protective base plate 1, a snap-fit ​​seat 2 on one side of the base plate 1, and a plug-in block 3 that mates with the snap-fit ​​seat 2 on the other side. Both the snap-fit ​​seat 2 and the plug-in block 3 have positioning holes 4. A guide rod 5 is installed through the bottom of the plate 1, and an adjusting block 6 is connected to the guide rod 5. A universal guide wheel 7 is installed at the lower end of the adjusting block 6, and a grounding pin 8 is installed at the upper end of the adjusting block 6. A locking nut 9 is connected to one end of the guide rod 5 that extends out of the protective plate 1. The outer wall of the plug-in block 3 and the inner wall of the snap-fit ​​seat 2 fit together. The cross-section of the snap-fit ​​seat 2 is set as a "U" shaped structure. The guide rod 5 can rotate on the protective plate 1. The surface of the end of the guide rod 5 that extends out of the protective plate 1 is provided with threads. The threaded section of the guide rod 5 that extends out of the protective plate 1 is threadedly connected to the locking nut 9. The side of the locking nut 9 facing the protective plate 1 is set as a rough surface. The positioning holes 4 opened on the plug-in block 3 and the positioning holes 4 opened on the snap-fit ​​seat 2 correspond one-to-one.

[0033] In the initial state, the universal guide wheel 7 is located at the lower end of the adjusting block 6, while the grounding pin 8 is located above the adjusting block 6. During subsequent handling of the protective substrate 1, the contact between the universal guide wheel 7 and the ground facilitates pushing the protective substrate 1, avoiding manual handling and increasing the deployment speed of the protective device. Furthermore, the grounding pin 8 is housed inside the protective substrate 1, preventing injury to workers from exposed grounding pins during deployment. Once the protective substrate 1 is moved to the appropriate position, rotating the guide rod 5 causes the adjusting block 6 to rotate synchronously. By rotating the adjusting block 6, the universal guide wheel 7 and the grounding pin 8 can be swapped. After adjusting the position of the grounding pin 8, tighten the locking nut 9 so that the locking nut 9 presses against the side of the protective base plate 1, thereby fixing the position of the adjusting block 6. Insert the plug 3 on the side of the protective base plate 1 into the corresponding snap-fit ​​seat 2 on the side of another protective base plate 1, and use bolts to pass through the positioning holes 4 on the snap-fit ​​seat 2 and the plug 3 to complete the fixation between the two. The grounding pin 8 at the bottom of the protective base plate 1 can be easily inserted into the soil to complete the initial fixation of the protective base plate 1.

[0034] Example 2: The technical content disclosed in this example is a further improvement on the basis of Example 1 above. The following technical content is disclosed in this example: a buffer side plate 10 is provided on the side of the protective substrate 1, and the buffer side plate 10 is connected to the protective substrate 1 through an auxiliary spring 11. The upper end of the buffer side plate 10 extends outward to form an inclined bending part, and a plurality of auxiliary springs 11 are evenly distributed between the buffer side plate 10 and the protective substrate 1.

[0035] During the blast, the workers stand behind the protective base plate 1. When the debris generated during the blast comes into contact with the buffer side plate 10, the movement of the buffer side plate 10 causes the auxiliary spring 11 to deform. The elastic deformation of the auxiliary spring 11 can thus play a buffering role. At the same time, the top of the buffer side plate 10 is provided with an inclined bending part, which can block the debris falling from above and guide the falling debris to slide down.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
