Description

Technical Field

[0001] The utility model relates to the technical field of mining engineering, in particular to a rockfall protection structure for mining quarrying equipment. Background Art

[0002] Mines include coal mines, metal mines, non-metallic mines, building materials mines and chemical mines, etc. There is a risk of rockfall on the surface of the mountain in the mine. Rockfall is the simplest and most common form of landslide. Any mountain will continue to experience rockfalls of varying sizes under the influence of gravity, wind or other factors. Rockfalls occurring during mine management will cause disasters and result in loss of property and life.

[0003] The existing rockfall protection devices for quarrying equipment are equipped with protective nets, metal mesh coverings and other structures. When falling rocks hit the protective structure, the impact force can be dispersed, thereby reducing the damage to the protective structure itself and its supporting foundation. However, there are also shortcomings. The adaptability is too low and it cannot be used in various working environments. For this reason, we propose a rockfall protection structure for quarrying equipment to solve the above problems. Utility Model Content

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4In the utility model, a rockfall protection structure for mining quarrying equipment includes a base 1, the upper surface of the base 1 is connected with a connecting block 13, the upper surface of the connecting block 13 is rotatably connected with a rotating shaft 14, the outer surface of the rotating shaft 14 is connected with a first baffle 12, the inner wall of the first baffle 12 is slidably connected with a second baffle 10, the left and right sides of the first baffle 12 are each provided with a group of card grooves 16, the left and right sides of the second baffle 10 are each provided with a card block 15, and the front of the second baffle 10 is equipped with two handles 11, the upper surface of the base 1 is connected with two first U-shaped blocks 6, the inner wall of each first U-shaped block 6 is hinged with a lower support 7, and the front of the first baffle 12 is connected with two second U-shaped blocks 9.

[0023] A set of conical feet 2 are installed on the bottom surface of the base 1. The installation of the conical feet 2 can make the structure more stable. Two slots 5 are provided on the upper surface of the base 1.

[0024] The right side of the base 1 is connected to two first connecting pieces 3, and the left side of the base 1 is connected to two second connecting pieces 4. The two connecting pieces can be connected to other protective structures to make them more stable.

[0025] The inner wall of each second U-shaped block 9 is hinged with an upper support 8, and the end of each lower support 7 away from the first U-shaped block 6 is provided with a U-shaped groove 22. Through the design of the rotating connection, the upper support 8 can rotate on the inner wall of the U-shaped groove 22, and the angle can be adjusted or folded for better transportation. The end of each upper support 8 away from the first baffle 12 is hinged on the inner wall of the U-shaped groove 22.

[0026] The left and right sides of each upper support 8 are hinged with a stop block 21. The combination of the stop block 21 and the stop groove 23 can limit the movement range of the upper support 8 on the lower support 7 to prevent excessive displacement of the support due to excessive impact force, thereby ensuring the stability of the protective structure. The left and right sides of each lower support 7 are provided with a stop groove 23.

[0027] A group of connecting columns 19 are threadedly connected to the back of the first baffle 12, and a metal mesh 20 is commonly connected to the back of the group of connecting columns 19. The metal mesh 20 can effectively intercept falling rocks and prevent them from directly hitting the baffle or personnel and equipment below, thereby improving the safety of the overall protective structure.

[0028] A group of springs 18 are connected to the back of the metal mesh 20. The springs 18 can provide elastic buffering. When falling rocks impact the protective mesh 17, the springs 18 can absorb and disperse the impact force, reducing the direct impact on the overall structure. The backs of a group of springs 18 are commonly connected to the protective mesh 17.

[0029] The working principle of the utility model is: the conical support foot 2 is inserted into the ground to fix the whole, and is connected to other equipment or protective devices through the first connecting piece 3 and the second connecting piece 4 to form a whole, and the protective plate is opened by rotating the rotating shaft 14 on the connecting block 13, and the rotation of multiple U-shaped blocks supports the protective plate. After it is supported, the stop block 21 is inserted into the stop groove 23 to completely fix it. In different environments, the second baffle plate 10 can be pulled up by the handle 11, and the second baffle plate 10 is limited by the card slot 16 and the card block 15. There are threaded holes on the back of the second baffle plate 10 for installing the protective net 17. When rockfall occurs, the first thing that the rockfall touches is the protective net 17 or the metal net 20. These nets provide buffering through the spring 18 to reduce the impact force of the rockfall.
