Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower civil engineering technology, specifically to a rapid deployment and retraction device for a water hose in tunnel drilling and blasting construction. Background Technology

[0002] In tunnel drilling and blasting construction, as the tunnel face advances, air and water supply pipelines need to be extended to the vicinity of the face to meet construction requirements. Typically, 6-meter-long welded pipes are used for these pipelines, connected by flanges. However, due to the impact of flying rocks during blasting, the pipelines within a 30-meter radius of the face are easily damaged. Therefore, this section of pipeline is usually replaced with a flexible rubber hose instead of a rigid welded pipe, allowing it to be retracted before blasting to prevent damage from flying rocks.

[0003] However, in actual construction, the following technical problems urgently need to be solved in the deployment and retraction of the feng shui hose: 1. Low hose deployment and retraction efficiency: Traditional methods mainly rely on manual operation to retract or release the hose from the working face. Due to the long length and heavy weight of the hose, manual deployment and retraction are time-consuming and labor-intensive, seriously affecting construction efficiency. 2. Chaotic construction site management: The lack of effective fixing and classification management of the hose during deployment and retraction easily leads to messy pipelines, affecting the standardized layout and civilized construction image of the construction site. 3. Prominent safety hazards: The hose is prone to entanglement with other pipelines during deployment and retraction, which not only increases the difficulty of operation but may also cause safety accidents. In addition, if the hose is not retracted in time, it is easily damaged by flying rocks from blasting, resulting in construction interruption and increased maintenance costs. 4. Short equipment lifespan: Due to frequent dragging and exposure to harsh environments, the wear rate of the hose is accelerated, and its lifespan is significantly shortened, further increasing construction costs.

[0004] To address the aforementioned issues, there is an urgent need to design a device capable of rapidly deploying and retracting the hydraulic hose. This device would effectively protect the hose from damage caused by flying rocks during blasting, improve the efficiency of hose deployment and retraction, standardize the layout of facilities at the construction site, reduce safety risks, and thus achieve efficient and standardized management of tunnel drilling and blasting construction. Utility Model Content

[0005] To solve the above problems, this utility model provides a quick-release and retraction device for ventilation and water hoses in tunnel drilling and blasting construction.

[0006] The technical solution adopted in this utility model is as follows: A rapid deployment and retraction device for a flexible hose in tunnel drilling and blasting construction includes a recovery bin track fixedly installed on one side wall inside the tunnel, a hose recovery bin frame slidably installed on the recovery bin track, and the hose recovery bin frame can move back and forth along the tunnel excavation direction via the recovery bin track. Several hanging ears are fixedly installed on the frame of the recycling bin. The hanging ears are arranged in a matrix from high to low in four layers. The air supply hose, water supply hose, and two sets of drainage hoses are respectively wrapped and stored on the four layers of hanging ears.

[0007] Furthermore, the track of the recycling bin is made of channel steel, and the inside of the channel steel is coated with grease.

[0008] Furthermore, several expansion bolts are horizontally spaced at the bottom of the recycling bin track, and the recycling bin track is fixedly installed on one side wall inside the tunnel by the expansion bolts.

[0009] Furthermore, several fixed steel bars are horizontally spaced on one side wall inside the tunnel. The fixed steel bars are in contact with the upper surface of the hose recycling bin frame, and the fixed steel bars provide upper limit for the hose recycling bin frame.

[0010] Furthermore, the lug is L-shaped and is made of two square tubes welded together.

[0011] The quick-release and retraction device for ventilation and water hoses in tunnel drilling and blasting construction provided by this utility model has the following significant advantages: 1. Improved hose deployment and retrieval efficiency: By installing multiple layers of lugs on the recycling bin frame, hoses for air supply, water supply, and drainage are categorized and wound for safekeeping, achieving orderly management and rapid deployment and retrieval. The recycling bin track uses a channel steel design with grease applied inside to reduce sliding friction, allowing the hose recycling bin frame to move easily back and forth along the tunnel excavation direction, significantly improving the operational efficiency of hose deployment and retrieval.

[0012] 2. Protect hoses from damage: The recovery bin frame can move back and forth relative to the working face via the recovery bin track, avoiding direct impact of flying rocks from blasting on the hoses, effectively extending the service life of the hoses and reducing maintenance and replacement costs.

[0013] 3. Standardize the construction site layout: The fixed installation of recycling bin tracks and fixed steel bars limits the position of the hose recycling bin frame, ensuring the stability of the hose recycling bin frame; air supply, water supply, drainage hoses are classified, wrapped and stored, avoiding the phenomenon of hoses being dragged and piled up indiscriminately, thus improving the standardization and civilized construction level of the construction site.

[0014] 4. Reduced Safety Risks: Categorized and orderly management of hoses for air supply, water supply, and drainage reduces tangling and avoids safety hazards caused by chaotic wiring. The movable recovery unit allows for rapid retraction of hoses before blasting, further reducing the potential damage risk and ensuring construction safety.

[0015] In summary, this utility model not only solves the problems of low efficiency and significant safety hazards in traditional hose retraction methods, but also achieves efficient and standardized management of construction sites through scientific design, and has broad application prospects and promotional value.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] This embodiment provides a rapid deployment and retraction device for hydraulic hoses in tunnel drilling and blasting construction. This device can effectively solve the problems of low deployment and retraction efficiency, chaotic construction site management, significant safety hazards, and easy damage to hoses in traditional construction. It significantly improves the deployment and retraction efficiency of hoses, standardizes the construction site layout, reduces safety risks, and extends the service life of hoses.

[0019] Specifically, such as Figure 1 and Figure 2 As shown, the tunnel drilling and blasting construction water hose quick deployment and retraction device includes a recovery bin track 1 fixedly installed on one side wall 3 inside the tunnel, and a hose recovery bin frame 2 slidably installed on the recovery bin track 1. The hose recovery bin frame 2 can move back and forth along the tunnel excavation direction through the recovery bin track 1.

[0020] Among them, such as Figure 1 and Figure 2 As shown, the recycling bin track 1 is constructed from two 10-meter-long channel steels welded together. The length of the channel steel can be adjusted according to actual needs. The inner wall of the channel steel is coated with grease to reduce the sliding friction of the hose recycling bin frame 2. Considering the installation and fixation of the recycling bin track 1, as... Figure 1 , Figure 2 and Figure 3 As shown, a Φ12mm expansion bolt 8 is installed every 2 meters at the lower end of the channel steel. The Φ12mm expansion bolt 8 is installed after drilling holes in the tunnel wall 3 using an impact drill. After installation, the Φ12mm expansion bolt 8 is welded to the bottom of the channel steel to fix it, thereby fixing the position of the recovery bin track 1.

[0021] like Figure 1 and Figure 2 As shown, in this embodiment, the hose recycling bin frame 2 is a frame structure welded from 50mm×50mm×3mm galvanized square tubing. Its height and width dimensions are designed according to actual needs, while its length must be less than the length of the recycling bin track 1. After the welded hose recycling bin frame 2 is placed on the recycling bin track 1, it can move back and forth along the tunnel excavation direction. Furthermore, considering the limiting issue of the hose recycling bin frame, such as... Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, multiple Φ20mm fixed steel bars 9 are horizontally spaced 2 meters apart on one side wall 3 inside the tunnel. The fixed steel bars 9 are in contact with the upper surface of the hose recycling bin frame 2. The fixed steel bars 9 limit the hose recycling bin frame 2, ensuring that the hose recycling bin frame 2 can only move back and forth and cannot move up and down to get off the recycling bin track 1.

[0022] In addition, regarding the storage of the air supply hose 5, water supply hose 6, and two sets of drainage hoses 7, such as... Figure 1 and Figure 2 As shown, in this embodiment, several hanging ears 4 are fixedly installed on the recycling bin frame. These hanging ears 4 are arranged in a matrix, with four layers from high to low. The hanging ears 4 adopt an L-shaped structure, welded from two 20mm×20mm×2mm galvanized square tubes. The hanging ears 4 are arranged in a matrix of four layers, with a vertical spacing of 300mm and a horizontal spacing of 200mm between each layer. Specifically, the first layer of hanging ears 4 is used to wind the air supply hose 5, the second layer is used to wind the water supply hose 6, and the third and fourth layers are used to wind two sets of drainage hoses 7, respectively.

[0023] like Figure 1 and Figure 2As shown, the air supply hose 5, water supply hose 6, and two sets of drainage hoses 7 are respectively wound and stored on four layers of hanging ears 4. By setting up multiple layers of hanging ears 4 and sliding rails, the hoses are classified and managed and quickly retracted, significantly improving operational efficiency. The classified winding and storage of hoses avoids random dragging and haphazard stacking, improving the standardization and civilized construction level of the construction site. During use, the hose recovery frame 2 is moved forward manually, allowing the ends of the air supply hose 5, water supply hose 6, and drainage hose 7 to extend to the vicinity of the tunnel excavation face. When blasting is required, the hose recovery frame 2 is moved backward manually, allowing the hoses to be quickly retracted before blasting, effectively reducing the risk of damage to the hoses from flying rocks.

[0024] In summary, this rapid deployment and retraction device for hydraulic hoses in tunnel drilling and blasting construction significantly improves hose deployment and retraction efficiency, standardizes construction site layout, reduces safety risks, and extends hose service life. Its simple structure and convenient operation make it particularly suitable for tunnel drilling and blasting construction scenarios.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
