Description

Technical Field

[0001] The utility model relates to the technical field of tunnel separation structures, in particular to a tunnel separation structure and a ventilation and transportation double-row tunnel with variable diameters. Background Art

[0002] Metal mine underground tunnels, especially mine tunnels, are generally equipped with two safety exits, which are mainly used for transportation and ventilation. Due to the metallogenic conditions, special ventilation tunnels are generally not set up in the mine. However, due to the large number of metal mine excavation and mining projects, the air volume distribution is often insufficient. Therefore, when the mine ventilation volume does not match the design, the wind speed is significantly reduced, and the workers' body temperature rises significantly during operation.

[0003] In response to this situation, mines generally equip local ventilators with soft and hard air ducts for relay ventilation. However, when local ventilators are used in transport tunnels, the wind flow is often unstable, resulting in unstable air volume and pressure delivered to the mining face. At the same time, the existence of local ventilators occupies part of the space in the transport tunnel. If the air duct is too large, it will affect the transport space of the tunnel. If the air duct is too small, it will limit the ventilation effect. This conflict is particularly obvious when using hard air ducts.

[0004] In response to the above-mentioned problems, it is necessary to change the layout of the tunnels. It is necessary to design an improved tunnel separation structure and a variable-diameter ventilation and transportation double-row tunnel, which can not only separate independent ventilation tunnels on the basis of the original tunnels to achieve effective control of ventilation quality, but also flexibly change the cross-sectional dimensions of the transportation tunnels without affecting the transportation in the mine, so as to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a tunnel partition structure and a ventilation and transportation double-row tunnel with variable diameter.

[0007] The moving direction of the partition template and the sliding direction of the high-toughness partition cloth are arranged to be the same.

[0008] As a further improvement of the utility model, the movable structure includes a movable track arranged at the bottom of the original tunnel and a movable slide rail slidably connected to the movable track; the partition template, the movable track and the movable slide rail constitute a movable panel wall to realize the movement of the partition template in the width direction of the tunnel.

[0009] As a further improvement of the utility model, the movable slide rail is vertically arranged at the bottom of the partition template, and a supporting triangle plate is arranged between the partition template and the movable slide rail.

[0010] As a further improvement of the present invention, fixed pulleys slidably connected to the high-toughness partition cloth are provided at the upper and lower ends of the partition template, and the movement of the partition template drives the sliding and folding of the high-toughness partition cloth.

[0011] As a further improvement of the utility model, the lane separation structure also includes a partition cloth fixing pin arranged on the wall of the ventilation lane, and the partition cloth fixing pin fixes the upper and lower ends of the high-toughness partition cloth on the ventilation lane.

[0012] As a further improvement of the utility model, the partition cloth fixing pins are divided into upper fixing pins and lower fixing pins; based on the positioning function of the upper fixing pins, the lower fixing pins and the fixed pulleys symmetrically arranged above and below, the high-toughness partition cloth separates the airflow of the ventilation alley and the transport alley.

[0013] As a further improvement of the utility model, when the length of the tunnel is too long, a plurality of groups of partition templates are arranged to divide the tunnel.

[0014] As a further improvement of the present invention, the setting height of the partition template is close to the height of the original lane; the setting length of the movable track is greater than half of the original lane width.

[0015] In order to achieve the above-mentioned purpose of the utility model, the utility model also provides a variable-diameter ventilation and transportation double-lane lane, which includes the above-mentioned lane separation structure;

[0016] Based on the original lane, the lane separation structure divides the original lane into two parts: a ventilation lane and a transportation lane;

[0017] The high-toughness partition cloth is driven to slide and fold by the movement of the partition template, thereby achieving diameter change between the ventilation lane and the transport lane.

[0018] As a further improvement of the utility model, a ventilator and a ventilator fixing device are installed at the upper opening of the ventilation tunnel.

[0019] As a further improvement of the present invention, when the high-toughness partition cloth is in a folded state and the partition template is close to the ventilator, the cross-section of the ventilation tunnel is the minimum cross-sectional area of ​​the ventilation tunnel.

[0020] The beneficial effects of the utility model are:

[0021] 1. The variable-diameter double-lane ventilation and transportation lanes provided by the utility model realize dual-purpose ventilation and transportation lanes based on the lane separation structure, effectively avoiding functional confusion. At the same time, it avoids the problem of unreasonable layout of local fans, improves the ventilation effect, and can adjust the local ventilation system in time according to on-site needs. Thirdly, through flexible layout methods, the functions of the transportation lanes are liberated, the essential functions of the transportation lanes are further optimized, and the utilization efficiency and reliability of the transportation lanes are improved.

[0022] 2. The variable-diameter double-row ventilation and transportation tunnel provided by the utility model is mainly used for the temporary construction of special ventilation tunnels to alleviate the problem of insufficient ventilation wind speed in the mine. It has four technical advantages: First, based on the tunnel separation structure, an independent ventilation tunnel is set up, and the wind speed is adjusted when the tunnel wind volume remains unchanged, so as to achieve the purpose of reducing the perceived temperature. Second, the installation limitations of local ventilators are optimized. There is no need to install local ventilators and supporting air ducts, which can better protect the ventilation system during the mine transportation process and optimize the ventilation efficiency. Third, the influence of ventilation wind speed on dust in the transport tunnel is eliminated, so that the ventilation system can be better optimized. Fourth, the tunnel space is effectively utilized. Through the variable-diameter tunnel, on the one hand, the ventilation problem can be improved, and on the other hand, when space is needed for transportation, sufficient space can be provided for the transport tunnel by changing the diameter, and when no transportation is carried out, the ventilation can be adjusted as needed.

[0030] See also Figure 1 to Figure 2 As shown, the utility model provides a tunnel partition structure in a double-row tunnel for ventilated transportation with variable diameter, which includes a partition template 3, a high-toughness partition cloth 2, a movable slide rail 5, a movable track 6, a partition cloth fixing pin 7, a fixed pulley 1 and a supporting triangle plate 4.

[0031] The partition template 3 is used to divide the original tunnel into two parts: a ventilation tunnel 8 and a transportation tunnel 9.

[0032] The high-toughness partition cloth 2 is slidably connected to the partition template 3 .

[0033] The moving direction of the partition template 3 and the sliding direction of the high-toughness partition cloth 2 are set to be the same.

[0034] The movable track 6 is arranged at the bottom of the lane, and the movable slide rail 5 is slidably connected to the movable track 6 to realize the movement of the partition template 3 in the width direction of the lane.

[0035] The movable slide rail 5 is vertically arranged at the bottom of the partition template 3, and a supporting triangular plate 4 is arranged between the partition template 3 and the movable slide rail 5. The movable slide rail 5 drives the partition template 3 to move, so as to realize the bidirectional diameter change between the ventilation lane 8 and the transport lane 9.

[0036] Fixed pulleys 1 are provided at the upper and lower ends of the partition template 3 and are slidably connected to the high-toughness partition cloth 2 , so as to enable the high-toughness partition cloth 2 to slide and fold.

[0037] The wall of the ventilation tunnel 8 is provided with partition cloth fixing pins 7 , and the partition cloth fixing pins 7 fix the two ends of the high-toughness partition cloth 2 on the ventilation tunnel 8 .

[0038] In some specific embodiments, the separator cloth fixing pin 7 is divided into an upper fixing pin and a lower fixing pin; based on the positioning function of the upper fixing pin, the lower fixing pin and the fixed pulley 1 symmetrically arranged above and below, the high-toughness separator cloth 2 separates the airflow of the ventilation channel 8 and the transport channel 9.

[0039] A ventilator 10 and a ventilator fixing device are installed at the upper opening of the ventilation tunnel 8.

[0040] When the high-toughness partition cloth 2 is in a folded state and the partition template 3 is close to the ventilator 10, the cross-section of the ventilation tunnel 8 is the minimum cross-sectional area of ​​the ventilation tunnel.

[0041] The height of the partition template 3 is close to the height of the original lane; the length of the movable track 6 is greater than half of the lane width.

[0042] When the tunnel is long, several groups of partition templates 3 of predetermined lengths are arranged to partition the long tunnel.

[0043] The utility model provides a variable-diameter ventilation and transportation double-row lane, which mainly uses a lane dividing structure to divide the original transportation lane into two parts, one is the transportation lane, and the other is the ventilation lane.

[0044] The premise of using this variable-diameter ventilation and transportation double-lane lane is to appropriately expand the span of the original lane and use the lane separation structure to divide the original lane into a transportation lane and a ventilation lane. The transportation lane continues to play its original transportation function, and the ventilation lane is equipped with a ventilator and a ventilator fixing device at the top to play the function of a dedicated ventilation lane.

[0045] The tunnel separation structure is the main structure for this type of tunnel to function, and is mainly composed of 7 parts, namely, a fixed pulley 1 fixed on the partition plate, a high-toughness partition cloth 2, a partition template 3, a supporting triangle plate 4, a movable slide rail 5, a movable track 6, and a partition cloth fixing pin 7.

[0046] Among them, the fixed pulley 1 fixed on the partition plate is mainly used for the sliding and folding of the high-toughness partition cloth 2. The high-toughness partition cloth 2 is mainly used to separate the airflow of the ventilation lane 8 and the transportation lane 9. The partition template 3, the supporting triangle plate 4, the movable slide rail 5, and the movable track 6 form a movable plate wall to achieve the purpose of variable diameter of the lane. The partition cloth fixing pin 7 fixes the high-toughness partition cloth 2 on the ventilation lane, which not only plays the role of fixing the high-toughness partition cloth 2, but also determines the minimum cross-sectional area of ​​the ventilation lane.

[0047] Example 1

[0048] Embodiment 1 of the present invention provides a variable-diameter double-lane ventilation transport tunnel. Based on the original tunnel conditions, a tunnel separation structure is used to separate the tunnels. The specific configuration is as follows:

[0049] When the air flow rate allocated to the A mining area is reduced, the wind speed in the original transport lane is reduced when it is used for ventilation, and it cannot meet the ventilation needs of the mining area. At this time, the two lanes of the mining area are converted into variable-diameter ventilation and transportation double-lane lanes.

[0050] By moving the movable slide rail 5, the partition template 3 is driven to move on the movable track 6, so that the high-toughness partition cloth 2 is folded, so as to achieve the purpose of changing the cross-sectional size of the dedicated ventilation tunnel. While ensuring that the air volume remains unchanged, the reasonable air flow speed is adjusted to improve the ventilation system.

[0051] When the B mining area adjacent to the A mining area is closed and separated, the wind flow is not adjusted in time, resulting in an increase in the air intake of the A mining area. The cross-section of the dedicated ventilation tunnel can be appropriately increased to achieve the purpose of reducing the wind speed.

[0052] Example 2

[0053] Embodiment 2 of the present invention provides a variable-diameter ventilation transport double-lane laneway. Based on the original lane conditions, a lane separation structure is used to separate the lanes. The specific configuration is as follows:

[0054] When using a variable-diameter ventilated transport double-lane tunnel, if large transport vehicles need to pass through, the transport tunnel section is insufficient, or the passing distance is insufficient, the transport tunnel 9 section can be expanded by moving the partition template 3. After the large vehicle passes, the partition template 3 can be moved to restore it to its original state, which greatly reduces labor, financial and other costs, and effectively achieves cost reduction and efficiency improvement.

[0055] The use of tunnel separation structures can make the cross-sectional span of the transport tunnel more flexible and more effectively play its essential function.

[0056] In summary, the utility model provides a tunnel partition structure and a variable-diameter ventilation and transportation double-row tunnel. The tunnel partition structure includes a partition template 3, a high-toughness partition cloth 2, a movable slide rail 5, a movable track 6, a partition cloth fixing pin 7, a fixed pulley 1 and a supporting triangle plate 4. The variable-diameter ventilation and transportation double-row tunnel provided by the utility model mainly uses the tunnel partition structure to divide the original transportation tunnel into two parts, one is the transportation tunnel, and the other is the ventilation-only tunnel. The premise of using the variable-diameter ventilation and transportation double-row tunnel is to appropriately expand the span of the original tunnel, and use the tunnel partition structure to divide the original tunnel into a transportation tunnel and a ventilation-only tunnel. The transportation tunnel continues to play its original transportation function, and a ventilator and a ventilator fixing device are installed at the top of the ventilation tunnel to play the function of a dedicated ventilation tunnel. Based on the tunnel partition structure, ventilation and transportation are dual-purpose in one tunnel, which effectively avoids mixed functions. At the same time, it avoids the problem of unreasonable layout of local fans, improves the ventilation effect, and can adjust the local ventilation system in time according to on-site needs. Thirdly, through the flexible layout, the functions of the transport lanes are liberated, the essential functions of the transport lanes are further optimized, and the efficiency and reliability of the transport lanes are improved. Thirdly, the lane separation structure used in this type of lane can be operated by one person, which is of great help to safe and efficient production and significantly saves manpower.

Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
