Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of slope blasting construction, in particular to a slope pre-splitting blasting support device. Background Technique
[0002] Slope pre-splitting blasting is a controlled blasting technique. Its background technique is mainly based on the principle of stress wave propagation and reflection. By reasonably designing blasting parameters, a through crack is formed along the designed contour line in front of the main blasting area to protect the reserved rock mass and obtain a flat slope contour.
[0003] During slope pre-splitting blasting, the mountain rocks will spread outwards with the blasting. Generally, the on-site equipment will evacuate them beyond the theoretically dangerous range. However, there will always be some mountain rocks that are suitable for rolling due to their shape or are pushed by mutual impact, which will cause the mountain rocks to exceed the dangerous range, thus causing damage to the peripheral equipment. Therefore, it is necessary to propose a slope pre-splitting blasting support device. Content of the Utility Model
[0004] The purpose of the utility model is to provide a slope pre-splitting blasting support device to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A slope pre-splitting blasting support device, including a baffle. A T-shaped chute is opened on the outer side wall of the baffle. A T-shaped slider is slidably connected in the T-shaped chute. The T-shaped slider extends outside the baffle and is fixedly connected with a bulldozing plate. A fixing hole is penetrated through the bottom wall of the T-shaped chute. A fixing nail is fixedly connected to the lower surface of the T-shaped slider. A threaded hole is opened on the top wall of the T-shaped chute. A threaded rod is threadedly connected in the threaded hole. The lower end of the threaded rod extends into the T-shaped chute and is rotationally connected with the T-shaped slider through a bearing.
[0006] Preferably, the upper end of the threaded rod passes through the upper orifice of the threaded hole and extends outside the baffle, and a rotating handle is fixedly connected to the upper end of the threaded rod.
[0007] Preferably, the lower end of the fixing nail extends into the fixing hole, and the fixing nail is slidably connected in the fixing hole.
[0008] Preferably, the bulldozing plate is arranged in an L shape, and the short end of the bulldozing plate is arranged in a slope shape.
[0009] Preferably, the T-shaped chute, the fixing hole and the threaded hole are all arranged vertically.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: during use, by rotating the threaded rod to drive the T-shaped slider to descend, the T-shaped slider will drive the fixing nail and the earth pushing plate to descend. The fixing nail will be inserted into the soil, and the earth pushing plate will be buried in the soil. After the baffle is impacted, the fixing nail will support the baffle, and the baffle will push the earth pushing plate, and the earth pushing plate will gather soil to increase resistance, so that the baffle can block the rock and avoid harm to equipment personnel.

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] As Figures 1 - 4 shown, the present utility model provides the following technical solutions:
[0018] Embodiment 1: A slope pre-splitting blasting support device, including a baffle 1, a T-shaped chute 2 is opened on the outer side wall of the baffle 1, a T-shaped slider 3 is slidably connected in the T-shaped chute 2, the T-shaped slider 3 extends outside the baffle 1 and is fixedly connected with an earth pushing plate 4, a fixing hole 5 is penetrated through the bottom wall of the T-shaped chute 2, a fixing nail 6 is fixedly connected to the lower surface of the T-shaped slider 3, a threaded hole 7 is opened on the top wall of the T-shaped chute 2, a threaded rod 8 is threadedly connected in the threaded hole 7, and the lower end of the threaded rod 8 extends into the T-shaped chute 2 and is rotatably connected with the T-shaped slider 3 through a bearing;
[0019] During use, first dig a shallow pit at the installation position of the baffle 1, then rotate the threaded rod 8. The threaded rod 8 descends in the threaded hole 7. When the threaded rod 8 descends, it will push the T-shaped slider 3 to descend synchronously. The T-shaped slider 3 will drive the fixing nail 6 and the earth-pushing plate 4 to descend synchronously. The fixing nail 6 will be inserted into the soil, and the earth-pushing plate 4 will descend into the shallow pit. When the baffle 1 is impacted, the fixing nail 6 will support the baffle 1. When the impact force is large and causes the baffle 1 to retreat, the earth-pushing plate 4 will shovel up the soil and accumulate it on the earth-pushing plate 4, thereby increasing its resistance and further supporting the baffle 1, so that the baffle 1 can block the rock and prevent equipment personnel from being injured.
[0020] Embodiment 2: The technical solution of this embodiment different from that of Embodiment 1 includes:
[0021] Among them, the upper end of the threaded rod 8 passes through the upper hole opening of the threaded hole 7 and extends outside the baffle 1. A rotating handle 9 is fixedly connected to the upper end of the threaded rod 8, and the threaded rod 8 can be rotated by rotating the rotating handle 9.
[0022] Among them, the lower end of the fixing nail 6 extends into the fixing hole 5, and the fixing nail 6 is slidably connected in the fixing hole 5. During use, the fixing nail 6 can be stored in the fixing hole 5, thus facilitating the storage and transportation of the baffle 1.
[0023] Among them, the earth-pushing plate 4 is arranged in an L shape, and the short end of the earth-pushing plate 4 is arranged in a slope, so that the earth-pushing plate 4 can easily shovel up the soil through the slope.
[0024] Among them, the T-shaped sliding groove 2, the fixing hole 5 and the threaded hole 7 are all arranged vertically, so that the threaded hole 8, the T-shaped slider 3 and the fixing nail 6 can only move vertically up and down.
[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
