Description

Technical Field

[0001] This utility model relates to the field of blasting technology, and in particular to a blasting safety protection barrier. 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. To prevent flying rocks, gravel, and other objects from injuring people or damaging equipment, protective barriers are usually set up to isolate the blasting area from the external environment.

[0003] Existing protective fencing consists of protective panels and supporting components. The supporting components are located at the rear of the protective panels. When stones fly to the front of the protective panels, they create a backward impact force, and the supporting components support the panels, improving the protective effect of the fence. As stones come into contact with the front of the protective panels, they accumulate there, gradually reducing the supporting effect of the components and thus diminishing the protective effectiveness of the fence. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a blasting safety protection fence to improve the protective effect of the fence.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A blasting safety protective enclosure includes a base, a baffle plate on the top side of the base, and a support assembly on the rear side of the baffle plate. The support assembly consists of a support base and a hydraulic cylinder. The support base is connected to the top side of the base, the fixed end of the hydraulic cylinder is connected to the base, and the driving end of the hydraulic cylinder is connected to the rear side of the baffle plate. An upward-opening receiving groove is formed on the top side of the base, and the receiving groove is located on the front side of the baffle plate. The front side of the baffle plate is formed as an arc-shaped surface, and the bottom end of the baffle plate is located at the opening of the receiving groove. The center of the arc-shaped surface is located on the front side of the baffle plate.

[0007] The baffle blocks the rocks generated by blasting, and the support components support the baffle to improve its stability. Rocks that collide with the baffle roll down the curved surface to the bottom of the baffle and are stored in the receiving groove, which reduces the phenomenon of rocks accumulating in front of the baffle and improves the protective effect of the enclosure.

[0008] Optionally, a receiving member is provided in the receiving groove. The receiving member is horizontally positioned in the receiving groove and abuts against the inner wall of the receiving groove. An elastic member is vertically positioned between the receiving member and the receiving groove. The two ends of the elastic member are respectively connected to the bottom side of the receiving member and the bottom of the receiving groove. In the initial state, the elastic member is in a free state, and the top side of the receiving member is flush with the top side of the base.

[0009] When a stone falls onto the receiving component, the receiving component slides down, and the elastic element is compressed, making it easier for the stone to enter the receiving groove. This reduces the phenomenon of stones accumulating on the front side of the baffle and improves the protective effect of the enclosure.

[0010] Optionally, multiple elastic elements are provided, and the multiple elastic elements are provided at the four corners of the receiving element.

[0011] This improved the stability of the receiving components.

[0012] Optionally, the bottom of the receiving groove is provided with a telescopic drive assembly that drives the receiving member to reciprocate in the vertical direction.

[0013] The telescopic drive assembly can push the stones in the receiving tank upwards, making it easier for workers to clean the stones from the receiving tank.

[0014] Optionally, the telescopic drive assembly includes a telescopic drive component and a telescopic rod. The fixed end of the telescopic drive component is connected to the bottom of the receiving groove, and the driving end of the telescopic drive component is connected to the telescopic rod. The telescopic drive component drives the end of the telescopic rod away from the telescopic drive component to reciprocate in the vertical direction.

[0015] Optionally, the receiving element is an upward-opening receiving groove. In the initial state, the opening of the receiving groove is flush with the top side of the base, and the outer side wall of the receiving groove abuts against the inner side wall of the receiving groove.

[0016] Optionally, a buffer layer is provided on the front side of the baffle.

[0017] The buffer layer protects the surface of the baffle, reduces damage to the baffle surface, reduces stone bounce, and improves the accuracy of stone entering the receiving groove.

[0018] The beneficial effects of this utility model are as follows: the baffle blocks the rocks generated by blasting, the support component supports the baffle to improve its stability, the rocks that collide with the baffle roll down the curved surface to the bottom of the baffle and fall above the receiving component, the receiving component slides down and the elastic element is compressed, which makes it easier for the rocks to enter the receiving groove, reducing the phenomenon of rocks accumulating in front of the baffle, and the telescopic drive component can push the rocks in the receiving groove upward, which makes it easier for workers to clean the rocks in the receiving groove and improves the protective effect of the enclosure.

[0022] Please see Figure 1 This utility model provides a blasting safety protection barrier.

[0023] A blasting safety protective enclosure includes a base 1, a baffle 2 on the top side of the base 1, a support assembly on the rear side of the baffle 2, and an upward-opening receiving groove 5 on the top side of the base 1. The receiving groove 5 is located on the front side of the baffle 2, and extends along the left-right direction of the base 1. The length of the receiving groove 5 is greater than the length of the baffle 2. The front side of the baffle 2 is configured as an arc-shaped surface 21, with the bottom end of the baffle 2 located at the opening of the receiving groove 5. The center of the arc-shaped surface 21 is located on the front side of the baffle 2. The blasting generates rocks that act as a barrier, and the support components support the baffle 2 to improve its stability. Rocks that collide with the baffle 2 roll off the curved surface 21 to the bottom of the baffle 2 and enter the receiving groove 5 for storage. This reduces the accumulation of rocks in front of the baffle 2 and improves the protective effect of the enclosure. A buffer layer 22 is provided on the front of the baffle 2. The buffer layer 22 protects the surface of the baffle 2, reduces damage to the surface of the baffle 2, reduces rock rebound, and improves the accuracy of the rocks entering the receiving groove 5.

[0024] The support assembly consists of a support base 3 and a hydraulic cylinder 4. The support base 3 is fixedly connected to the top side of the base 1. The fixed end of the hydraulic cylinder 4 is detachably connected to the base 1 by a locking bolt. The driving end of the hydraulic cylinder 4 is fixedly connected to the rear side of the baffle 2. By driving the baffle 2 through the hydraulic cylinder 4, the distance between the bottom side of the baffle 2 and the receiving groove 5 can be adjusted.

[0025] A receiving member 6 is provided inside the receiving groove 5. The receiving member 6 is horizontally positioned inside the receiving groove 5, and its four sides abut against the inner wall of the receiving groove 5. Multiple elastic members 7 are vertically arranged between the receiving member 6 and the receiving groove 5. The two ends of the elastic members 7 are fixedly connected to the bottom side of the receiving member 6 and the bottom of the receiving groove 5, respectively. The multiple elastic members 7 are respectively located at the four corners of the receiving member 6, which improves the stability of the receiving member 6. In this embodiment, the elastic members 7 are compression springs, and the receiving member 6 is a receiving groove with its opening facing upward. In the initial state, the elastic members 7 are in a free state, the opening of the receiving groove is flush with the top side of the base 1, and the outer side wall of the receiving groove abuts against the inner side wall of the receiving groove 5. When a stone falls on top of the receiving member 6, the receiving member 6 slides down, and the elastic members 7 are compressed, which facilitates the stone entering the receiving groove 5, reduces the phenomenon of stone accumulation on the front side of the baffle 2, and improves the protective effect of the enclosure.

[0026] The bottom of the receiving trough 5 is provided with a telescopic drive assembly that drives the receiving component 6 to reciprocate vertically. The telescopic drive assembly includes a telescopic drive component 8 and a telescopic rod 9. The fixed end of the telescopic drive component 8 is connected to the center of the bottom of the receiving trough 5, and the driving end of the telescopic drive component 8 is connected to the telescopic rod 9. The telescopic drive component 8 drives the end of the telescopic rod 9 away from the telescopic drive component 8 to reciprocate vertically. When the elastic element 7 is compressed to the bottom side of the receiving trough and abuts against the top of the telescopic rod 9, the explosion stops. The telescopic drive component 8 drives the telescopic rod 9 to move upward, thereby pushing the stones in the receiving trough upward, making it easier for workers to clean the stones in the receiving trough 5. In this embodiment, the telescopic drive component 8 is a telescopic cylinder.
