[0025] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0026] In the present disclosure, unless otherwise specified, directional words such as "inside and outside" refer to the "inside and outside" relative to the own contour of the corresponding component, and "top and bottom" refer to the "top and bottom" of the present disclosure along the height direction when in use. In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another, and do not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0027] According to a specific embodiment of the present disclosure, a tunnel roof support device is provided, referring to Figures 1 to 3 As shown in the figure, the tunnel roof support device includes a support plate 5 and a mounting seat 1. The support plate 5 is installed on the mounting seat 1 through a first support structure and a second support structure. The first support structure is arranged at the center of the support plate 5. There are multiple second support structures. The multiple second support structures are arranged around the first support structure and at intervals along the circumference of the support plate 5. The support plate 5 is used to abut against the tunnel roof.

[0028] Through the above technical scheme, in the tunnel roof support device provided by the present invention, the first support structure is arranged at the center of the support plate 5, and can support the central position of the support plate 5. Multiple second support structures are arranged at intervals along the circumference of the support plate 5, which can not only support the support plate 5 around one circle, but also share the pressure borne by the first support structure, thereby ensuring the support effect of the support plate 5 and eliminating safety hazards.

[0029] It should be noted that the number of the second supporting structures can be two, three, four, etc. Figure 1 and Figure 4 Only two examples are used to facilitate understanding, and the present disclosure does not make specific limitations on this.

[0030] In the tunnel roof support device provided in the present disclosure, the first support structure can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 1 and Figure 2 As shown in , the first support structure may include a first telescopic rod 8013 and a first elastic member 8014. The two ends of the first telescopic rod 8013 may be fixed to the mounting seat 1 and the supporting plate 5, respectively. The first elastic member 8014 may be sleeved on the first telescopic rod 8013, and the two ends may abut against the mounting seat 1 and the supporting plate 5, respectively. The first elastic member 8014 is sleeved on the first telescopic rod 8013, so the first elastic member 8014 can be elastically deformed along the axial direction of the first telescopic rod 8013. In this way, the first elastic member 8014 can support the supporting plate 5 to ensure the supporting effect of the supporting plate 5 on the tunnel roof; and when the supporting plate 5 is displaced, it can play a role in reducing the impact of heavy objects on the supporting plate 5 to prevent the tunnel roof support device from being damaged. In the present disclosure, by providing the first telescopic rod 8013, the support plate 5 can be moved up and down along the axial direction of the first telescopic rod 8013, thereby preventing the position of the support plate 5 from being offset, thereby improving the reliability of the tunnel roof support device.

[0031] In addition, the first elastic member 8014 can be constructed in any suitable manner. As an exemplary embodiment, the first elastic member 8014 can be constructed as a strong spring, which is not specifically limited in the present disclosure. Figure 5 and Figure 6 As shown in, a connecting rod 8016 and a baffle 8012 can be arranged below the support plate 5, and the two ends of the strong spring are respectively abutted against the baffle 8012 and the mounting seat 1, wherein the length of the connecting rod 8016 and the position of the baffle 8012 can be set according to actual needs, thereby controlling the compression degree of the strong spring, ensuring the supporting effect of the strong spring on the support plate 5, and ensuring the reliability of the first supporting structure.

[0032] In the tunnel roof support device provided in the present disclosure, the first telescopic rod 8013 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 1 and Figure 2 As shown in , the first telescopic rod 8013 can be constructed as a hydraulic rod. In this way, the hydraulic rod can provide a certain supporting effect on the supporting plate 5, and at the same time, the first elastic member 8014 can make the supporting plate 5 more stable.

[0033] In the tunnel roof support device provided in the present disclosure, the second support structure can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 1 and Figure 2 As shown in , the second support structure may include a rotating rod 804 and a connecting assembly. The first end of the rotating rod 804 can be rotatably mounted on the support plate 5, and the second end can be slidably mounted on the mounting seat 1. The connecting assembly can be installed between the mounting seat 1 and the second end along the sliding direction of the rotating rod 804. When the support plate 5 above the second support structure is deformed, the second end of the rotating rod 804 can slide on the mounting seat 1 to press the connecting assembly. In this embodiment, the second end of the rotating rod 804 can be tilted toward the circumference of the mounting seat 1, so that the force of the rotating rod 804 acting on the mounting seat 1 in the vertical direction can be dispersed, which is beneficial to the structural stability of the tunnel roof support device.

[0034] In the tunnel roof support device provided in the present disclosure, the connection assembly can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 1 , Figure 2 and Figure 4 As shown in , the second end can be rotatably mounted with a slider 805, the mounting seat 1 can be provided with a slide groove 801, the slider 805 can be slidably mounted in the slide groove 801, the connecting assembly can include a second telescopic rod 807 and a second elastic member 808, the two ends of the second telescopic rod 807 can be fixed to the slider 805 and the groove wall of the slide groove 801 respectively, and the second telescopic rod 807 can be arranged along the extension direction of the slide groove 801, the second elastic member 808 can be sleeved on the second telescopic rod 807, and the two ends can be respectively abutted against the slider 805 and the groove wall. Among them, the second elastic member 808 is sleeved on the second telescopic rod 807, so the second elastic member 808 can be elastically deformed along the axial direction of the second telescopic rod 807, so that the second elastic member 808 can support the slider 805 to support the support plate 5 through the rotating rod 804 to ensure the support effect of the support plate 5 on the tunnel roof; and can also play a role in slowing down the moving speed of the support plate 5 when the support plate 5 is displaced.

[0035] In addition, both ends of the second telescopic rod 807 are respectively fixed to the slider 805 and the slide groove 801, and the second telescopic rod 807 is arranged along the extension direction of the slide groove 801. On the one hand, it can ensure that the slider 805 slides along the extension direction of the slide groove 801, and on the other hand, it can prevent the slider 805 from slipping out of the slide groove 801.

[0036] In the tunnel roof support device provided in the present disclosure, the support plate 5 can be arranged in any suitable manner. As an exemplary embodiment, refer to Figure 1 and Figure 3 As shown in , the number of support plates 5 can be multiple, and a mounting groove 4 can be formed on the mounting seat 1, and multiple support plates 5 can be installed in the mounting groove 4 at intervals. In this way, compared with only setting one support plate 5, the support effect of using multiple support plates 5 is better. Specifically, multiple support plates 5 can better fit the shape of the tunnel roof, and at the same time, multiple support plates 5 can support various positions of the tunnel roof at the same time, so that the load-bearing performance of the tunnel roof support device is better. In addition, the provision of multiple support plates 5 can improve the economy of the tunnel roof support device. Specifically, when the support plate 5 is aged or damaged, only the corresponding support plate 5 needs to be replaced. In addition, the provision of the mounting groove 4 enables the first support structure and the second support structure to be arranged in the mounting groove 4 to protect the first support structure and the second support structure.

[0037] Among them, the area formed by multiple support plates 5 can be adapted to the shape of the part on the tunnel roof that needs to be supported. The accompanying drawings only use two support plates 5 as a schematic diagram to facilitate understanding and do not constitute a limitation to the present disclosure.

[0038] In the tunnel roof support device provided by the present disclosure, in order to further improve the reliability of the tunnel roof support device, as an exemplary embodiment, reference is made to Figure 1 and Figure 3 As shown in , the tunnel roof support device may also include a monitoring component, which may include a sensor 10, a sensing element 11, a controller and an audible and visual alarm device. One of the sensor 10 and the sensing element 11 may be installed on the mounting seat 1, and the other may be installed on the support plate 5. The sensing element 11 is used to sense the sensor 10, and the sensing element 11 and the audible and visual alarm device may be electrically connected to the controller. In this way, if the sensor 10 exceeds the sensing range of the sensing element 11, the sensing element 11 cannot sense the signal sent by the sensor 10, and the controller will control the audible and visual alarm device to alarm to prompt the staff. Among them, the sensor 10 exceeds the sensing range of the sensing element 11, indicating that the displacement of the support plate 5 exceeds the limit, that is, the tunnel roof at the corresponding position has undergone a more serious deformation.

[0039] In the present disclosure, the sensing range of the sensing element 11 can be reasonably set according to the specific requirements of the construction site. As an exemplary embodiment, the signal emitted by the installed sensor 10 can be transmitted to the center of the sensing range of the sensing element 11. The sensing range of the sensing element 11 can be set to 20 cm, that is, when the displacement of the support plate 5 away from or toward the mounting seat 1 exceeds 10 cm, the sound and light alarm device in the detection component can alarm to prompt the staff. In other embodiments, the sensing range of the sensing element 11 can also be selected to be 10 cm, 30 cm, etc., and the present disclosure does not make specific restrictions on this.

[0040] In the tunnel roof support device provided by the present disclosure, in order to further improve the reliability of the tunnel roof support device, as an exemplary embodiment, reference is made to Figure 1 As shown in , a mounting frame 9 may be provided between any two adjacent support plates 5, the mounting frame 9 may be vertically mounted on the bottom wall of the mounting groove 4, a sensor 10 may be installed on the side of the mounting frame 9 facing the support plate 5, and a sensing element 11 may be installed on the side of the support plate 5 facing the mounting frame 9. By providing the mounting frame 9, it is convenient to install the sensor 10 to monitor in real time whether the displacement of the support plate 5 exceeds the limit.

[0041] In the tunnel roof support device provided by the present disclosure, the sound and light alarm device can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 1 and Figure 3 As shown in , the sound and light alarm device may include a buzzer 3 and an alarm light 2, and the buzzer 3 and the alarm light 2 may be mounted on the outer side of the mounting base 1. In this way, it is convenient for the staff to find the prompts of the alarm light 2 and the buzzer 3 in time.

[0042] In the tunnel roof support device provided in the present disclosure, as an exemplary embodiment, reference is made to Figure 1 As shown in , the tunnel roof support device may also include a plurality of leg structures, which may be arranged at intervals along the circumference of the mounting seat 1. The leg structures may include a base 7 and at least one jack 6, and the two ends of the jack 6 may be connected to the base 7 and the bottom of the mounting seat 1, respectively. In this way, the jack 6 can drive the mounting seat 1 to move up and down, so that the tunnel roof support device is suitable for tunnels of different heights. In addition, by providing the base 7, the contact area between the jack 6 and the ground can be increased, and the pressure can be reduced.

[0043] During use of the tunnel roof support device provided by the present invention, it is necessary to first move the device to the position requiring support, and then use the jack 6 to lift the mounting seat 1 so that the support plate 5 abuts against the tunnel roof. If the sound and light alarm device sounds an alarm, the mounting seat 1 is lowered using the jack 6 to facilitate the operation of the staff.
