Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety protection shed technology, specifically a safety protection shed for underground support. Background Technology
[0002] In underground operations such as mining and tunnel excavation, complex and variable geological conditions pose constant threats to the lives of workers and the normal operation of equipment due to hazards such as roof collapse and rockfall. Therefore, underground support safety shelters are crucial facilities for ensuring the safety of underground operations, and their performance directly affects whether underground operations can be carried out safely and efficiently.
[0003] Currently, most commercially available underground support safety canopies employ relatively simple support structures. Some canopies rely solely on single steel pipe supports and wooden plank flooring. When subjected to significant impact, they struggle to effectively distribute pressure, leading to excessive stress at a single point, which can cause deformation or even collapse of the support structure, thus failing to provide reliable safety for underground operations. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a safety protection shed for downhole support.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A safety protection canopy for underground support includes:
[0007] First supporting steel pipe;
[0008] The second support steel pipe is axially adjustable and inserted into the first support steel pipe;
[0009] I-beams are fixed to the top of the second supporting steel pipe;
[0010] Several pieces of wood are arranged at equal intervals along the axial direction at the top of the I-beam;
[0011] An auxiliary component is horizontally positioned on the timber between the I-beams; the auxiliary component has a top bearing portion and a bottom pressing portion, the bearing portion and the pressing portion being spaced apart; adjacent timbers are respectively embedded in the bearing portion and the pressing portion, and the timber located in the pressing portion bears the vertical pressure of the timber located in the bearing portion, so as to disperse the pressure when the timber is impacted.
[0012] Preferably, it also includes multiple pin holes, arrayed in the second support steel pipe;
[0013] A fixing pin passes through a pin hole at the top of the first support steel pipe and at a selected position to fix the first support steel pipe and the second support steel pipe.
[0014] Preferably, the auxiliary component adopts a serpentine structure with a top opening and a bottom opening.
[0015] Preferably, the contact surfaces of the wood with the bearing part and the pressing part are provided with matching grooves, and the auxiliary parts are embedded in the grooves to make the wood joints tight.

[0017] Preferably, the auxiliary component is located in the middle of several pieces of wood to improve the integrity and load-bearing uniformity of the pieces of wood.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. Efficiently disperses impact force: Through the serpentine structure of the auxiliary parts and the spaced design of the load-bearing part and the pressing part, adjacent wood can transfer vertical pressure to each other, dispersing the impact force to multiple woods and avoiding excessive force on a single point, which could lead to component damage.
[0020] 2. Flexible adaptation to different heights: The second support steel pipe can be axially adjusted and inserted into the first support steel pipe. With the fixing structure of pin holes and fixing pins, the support height can be flexibly adjusted according to different underground environments to ensure the applicability of the protective canopy.
[0021] 3. Enhance overall stability: The vertical support structure composed of the first and second supporting steel pipes, combined with the lateral bearing capacity of the I-beams, the overall improvement of the wood by auxiliary components, and the circumferential auxiliary support at the bottom of the auxiliary legs, the synergistic effect of multiple components enhances the overall stability of the protective shed.
[0022] 4. Ensure operational safety: The components work together to distribute pressure and provide stable support, which can effectively cope with situations such as increased roof pressure and rockfall impact, and evenly transmit pressure to the underground surface, providing reliable safety protection for underground workers and equipment and reducing the risk of safety accidents.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model. Example
[0030] like Figure 1-4 As shown, a safety protection canopy for underground support includes:
[0031] First supporting steel pipe 1: As the basic supporting component of the protective shed, it provides a stable supporting base.
[0032] The second support steel pipe 2 is axially adjustable and inserted into the first support steel pipe 1. By adjusting its extension length, it can adapt to different downhole working environments. The second support steel pipe 2 has multiple pin holes 6 arranged in an array for fixing to the first support steel pipe 1.
[0033] I-beam 3: Fixed to the top of the second supporting steel pipe 2, it provides a lateral load-bearing and supporting structure for the protective shed, enhancing the overall stability.
[0034] Wood 4: Arranged equidistantly along the axial direction at the top of the I-beam 3, serving as the main load-bearing and protective component. Its contact surface with the auxiliary component 5 has a matching groove to ensure a tight fit.
[0035] Auxiliary component 5: It is horizontally arranged on the timbers 4 between the I-beams 3, and adopts a serpentine structure with openings at the top and bottom. It has a top bearing part 51 and a bottom pressing part 52, which are spaced apart. The auxiliary component 5 is located in the middle of several timbers 4, which can effectively improve the integrity and load uniformity of several timbers 4, and disperse the pressure when the timbers 4 are subjected to impact.
[0036] Pin hole 6: The array is opened in the second support steel pipe 2 and is used in conjunction with the fixing pin 7 to fix the first support steel pipe 1 and the second support steel pipe 2.
[0037] Fixed pin 7: Through the pin hole 6 at the top of the first supporting steel pipe 1 and the selected position, the first supporting steel pipe 1 and the second supporting steel pipe 2 are fixedly connected to ensure the stability of the supporting structure.
[0038] Auxiliary support legs 8: Multiple auxiliary support legs 8 are arrayed and installed around the bottom of the first support steel pipe 1, providing auxiliary support to the first support steel pipe 1 and further enhancing the stability of the protective shed.
[0039] When situations such as increased roof pressure or rockfall impact occur underground, the timbers 4, which are equidistantly arranged along the axial direction at the top of the I-beam 3, will bear the impact force first. At this time, the auxiliary component 5, which is horizontally set in the middle of the timbers 4, has a unique serpentine structure with a top bearing part 51 and a bottom pressing part 52 arranged at intervals. Adjacent timbers 4 are respectively embedded in the bearing part 51 and the pressing part 52.
[0040] Under impact, the timber 4 located in the bearing section 51 transmits the vertical pressure to the timber 4 located in the pressing section 52. In this way, the impact force is distributed to multiple timbers 4, preventing individual timbers 4 from being damaged due to excessive pressure. Simultaneously, the first supporting steel pipe 1 and the second supporting steel pipe 2 are fixed together by fixing pins 7 and pin holes 6, forming a stable vertical support structure that can effectively withstand and transmit the pressure on the timbers 4 and the I-beam 3. The second supporting steel pipe 2 is adjustablely inserted into the first supporting steel pipe 1, ensuring that the protective canopy maintains stable support in different downhole environments.
[0041] The I-beam 3 is fixed to the top of the second supporting steel pipe 2, providing lateral load-bearing and support for the protective canopy. Together with the timber 4 and auxiliary components 5, it disperses the impact force, ensuring that the entire protective canopy is subjected to uniform stress. The auxiliary support legs 8, arrayed and installed circumferentially at the bottom end of the first supporting steel pipe 1, further enhance the overall stability of the protective canopy, ensuring that when the protective canopy is impacted, the pressure can be effectively dispersed to the underground surface, thereby protecting the safety of underground workers and equipment.
[0042] Efficiently disperses impact force: Through the serpentine structure of the auxiliary component 5 and the spaced design of the bearing part 51 and the pressing part 52, adjacent wood pieces 4 can transfer vertical pressure to each other, dispersing the impact force to multiple wood pieces 4, avoiding excessive force on a single point that could damage the component.
[0043] Flexible adaptation to different heights: The second support steel pipe 2 can be axially adjusted and inserted into the first support steel pipe 1. With the fixing structure of the pin hole 6 and the fixing pin 7, the support height can be flexibly adjusted according to different underground environments to ensure the applicability of the protective canopy.
[0044] Enhancing overall stability: The vertical support structure formed by the first support steel pipe 1 and the second support steel pipe 2, combined with the lateral bearing capacity of the I-beam 3, the overall improvement of the integrity of the wood 4 by the auxiliary component 5, and the circumferential auxiliary support of the auxiliary leg 8 at the bottom, the synergistic effect of multiple components enhances the overall stability of the protective shed.
[0045] Ensuring operational safety: The components work together to distribute pressure and provide stable support, effectively dealing with situations such as increased roof pressure and rockfall impacts, and evenly transmitting pressure to the underground surface, providing reliable safety protection for underground workers and equipment, and reducing the risk of safety accidents.
[0046] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
