[0002] The slope refers to the slope surface with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. The development and excavation of the roadbed mainly adopts the blasting method. The rock is broken by the shock wave generated by the blasting and the pressure generated by the expansion of the gas.

[0003] In order to avoid road collapse during blasting, the slopes are protected by supporting equipment. Currently, due to the differences in the areas of the slopes themselves, the overall area of ​​the supporting equipment is relatively large, which is not only inconvenient for transportation but also for later storage and processing. The angles of the slopes are also different, which makes it difficult for the protective plates on the supporting equipment to fit closely to the slopes, leaving gaps between the slopes and the protective plates, making it difficult for the supporting equipment to protect the slopes.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A slope pre-splitting blasting support structure, comprising a support 1 located on both sides of the slope, and a positioning column 1 3 extending into the ground is integrally connected to the support 1, pillars 2 extending to the slope are connected to both ends of the support 1 by screws, and a positioning column 2 4 extending into the slope is integrally connected to the pillar 2, a pressure plate 5 is placed between the two pillars 2, the pillar 2 is installed at the two ends of the support 1 by screws, so that the angle between the support 1 and the pillar 2 can be adjusted according to the angle of the slope, and then the support 1 and the pillar 2 are limited by the positioning column 1 3 and the positioning column 2 4 respectively, and the pressure plate 5 can press the pillar 2 after installation;

[0021] The support 1 is provided with a card slot 1 6 and a card slot 2 7, the card slot 2 7 is horizontally arranged at both sides of the card slot 1 6, the guide rod 14 is vertically arranged, the pressure plate 5 is integrally connected with a handle, the card slot 1 6 is placed with a card plate 8, and the card plate 8 is integrally connected with a symmetrically arranged connection ear 1 9;

[0022] The second card slot 7 is provided with a base 11, and the base 11 is integrally connected with a second symmetrically arranged connecting ear 12. Before protecting the slope, the specifications of the card plate 8 and the base 11 can be selected according to the width of the slope, so that the card plate 8 and the base 11 can support slopes of different specifications after installation. The first connecting ear 9 is threadedly connected with a locking bolt 10 detachably connected to the support 1, and the second connecting ear 12 is threadedly connected with a locking bolt 13 detachably connected to the support 1;

[0023] A symmetrically arranged guide rod 14 is fixedly installed in the cardboard 8, a guide block 15 is slidably sleeved on the guide rod 14, and a protective plate 16 for protecting the slope is integrally connected between the two guide blocks 15, and a limit seat 17 is fixedly installed on the protective plate 16. The handrail on the limit seat 17 can be pulled by a mechanical arm or a crane, so that the two protective plates 16 can slide in the cardboard 8. When sliding, the protective plate 16 drives the guide block 15 to slide on the guide rod 14, so that the protective plate 16 extends out of both sides of the cardboard 8 and applies pressure to the slope below;

[0024] A self-locking shaft 18 driven by an external device is rotatably mounted on the base 11, and a limit plate 19 is wound up on the self-locking shaft 18. The base 11 is a concave structure, the self-locking shaft 18 is horizontally arranged, and a limit column 20 extending into the limit seat 17 is integrally connected to the limit plate 19. It is supplemented that the self-locking shaft 18 is opened and closed by an external device, which is a prior art. The limit plate 19 can be wound up or unfolded by the forward and reverse rotation of the self-locking shaft 18, and the limit plate 19 is made of a steel coil. It should be noted that the support 1 is mainly protected by the card plate 8 and the two protective plates 16 for the slope below, and the gap between the extended protective plate 16 and the limit column 20 is small.

[0025] The limit seat 17 and the protective plate 16 extend to one side outside the card plate 8, and a handrail is fixedly installed on the limit seat 17. The limit seat 17 is threaded with a fixing bolt that is detachably connected to the limit column 20. When the protective plate 16 extends out of the positions on both sides of the card plate 8, the self-locking shaft 18 immediately rotates and unfolds the limit plate 19. When the limit plate 19 is unfolded, the limit column 20 moves and extends into the limit seat 17, and then the limit seat 17 and the limit column 20 are connected through the fixing bolt, so that the protective plate 16 and the limit plate 19 are fitted with the slope below after connection, thereby supporting and protecting the slope below, so that the safety of the slope can be guaranteed during the later blasting.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] Transport the support 1 to the slope by a crane or a mechanical arm;

[0028] After the support 1 is placed on the slope, the positioning column 1 3 extends into the ground to limit the two supports 1, so that the two supports 1 can be located on both sides of the slope;

[0029] The pillars 2 are installed on both ends of the support 1 by screws, so that the two pillars 2 can extend to the top and bottom of the slope respectively, and the two pillars 2 extend to the ground of the slope through the positioning pillars 4;

[0030] The pressure plate 5 is installed on the pillar 2 so that the pressure plate 5 can apply pressure to the top and bottom of the slope for protection. The operator selects the specifications of the clamping plate 8 and the base 11 according to the specifications of the slope;

[0031] Place the card plate 8 in the card slot 1 6, and then place the base 11 in the card slot 2 7, use the locking bolt 10 to connect the connecting ear 1 9 to the support 1, and use the locking bolt 2 13 to connect the connecting ear 2 12 to the support 1;

[0032] The handrail is connected to the upper handrail by a crane or a mechanical arm and the handrail is pulled. When the handrail moves, the limit seat 17 and the protective plate 16 slide in the clamping plate 8. When the protective plate 16 moves, the guide block 15 slides on the guide rod 14. When the self-locking shaft 18 is rotated by an external device, the limit plate 19 is unfolded. When the limit plate 19 moves, the limit column 20 is extended into the limit seat 17. The limit seat 17 and the limit column 20 are connected by a fixing bolt.

[0033] Repeat the above steps to pull the lower handrail so that another limiting column 20 can extend into the lower limiting seat 17;

[0034] When the limiting column 20 extends into the limiting seat 17, the clamping plate 8, the protection plate 16 and the limiting plate 19 can support and protect the slope when covering, so that blasting operation can be carried out on the slope.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
