DETAILED DESCRIPTION

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 1-4 As shown, a tunnel curved side roof 1 laying device includes a main beam frame 2, a moving assembly 7 arranged under the main beam frame 2 and a plurality of variable support groups arranged on the main beam frame 2. The device is moved to the desired location for laying and installation by the moving assembly 7. The main beam frame 2 plays the main supporting role, and the plurality of variable support groups are used to support the curved side roof 1. It should be noted that in this embodiment, as shown in FIG. Figure 3 As shown, 6 groups of variable support groups are provided to support the arc-shaped side top plate 1 .

[0034] Each variable support group includes three support rods, each distributed around the main beam 2 in a circular pattern. Each support rod has a removable roller 6 mounted on its top. The axis of rotation of roller 6 is perpendicular to the main beam 2, meaning that the roller 6's rolling direction coincides with the length of the main beam 2. A first drive motor 9 is provided between the variable support groups to drive the rollers 6. The first drive motor 9 drives the rollers 6 to rotate, and the drive method is not limited. In this embodiment, a pulley is used. The rotation of roller 6 transports the curved side top plate 1 to a designated location.

[0035] Furthermore, each variable support group includes a first support rod 3 arranged vertically, a second support rod 4 and a third support rod 5 arranged in a symmetrical vertical plane; the second support rod 4 is a first hydraulic rod, and the third support rod 5 is a second hydraulic rod; the first support rod 3 is a fixed rod, and a driving motor drives the roller 6 on the top of the first support rod 3 to rotate. By changing the design of the second support rod 4 and the third support rod 5 to hydraulic rods, the arc radius between the support points on the first support rod 3, the second support rod 4 and the third support rod 5 can be changed by changing the length of the two, so as to adapt to more specifications of the curved side top plate 1, such as Figure 1 , as shown in 2, for example: the construction of a two-lane tunnel and a six-lane tunnel; of course, when this method is not adopted, different rollers 6 can also be replaced to increase adaptability. It should be noted that this change is small and the effect is not good.

[0036] In this embodiment, if Figure 3 As shown, the mobile assembly 7 is connected to the main beam 2 via a plurality of third hydraulic rods 8. The third hydraulic rods 8 can be used to raise or lower the main beam 2 relative to the mobile assembly 7 to facilitate construction; the mobile assembly 7 can be a mobile trolley, which can be commonly used in engineering, such as a steel plate trolley.

[0037] In this embodiment, the hydraulic systems of the first hydraulic rod, the second hydraulic rod and the third hydraulic rod 8 can be implemented using existing technologies, and the hydraulic pipes are arranged on the main beam 2; in addition, the first drive motor 9 drives the rollers 6 located at both ends of the main beam 2 to rotate. By rotating the rollers 6 at both ends, the effectiveness of use can be guaranteed, but it should be noted that the distance between the rollers 6 serving as driving wheels should not exceed the length of the curved side top plate 1.

[0038] Furthermore, in this embodiment, the roller 6 can be a general rubber wheel, but in order to ensure sufficient life and strength, in this embodiment, the following settings are adopted: Specifically, Figure 4 As shown, the roller 6 includes: a roller 61, a fixed plate 62 fixedly connected to the roller 61, and an anti-slip sleeve 65; the roller 61 is connected to the top of the support rod through a bearing, and the driving motor drives the roller 61 to rotate; the fixed plate 62 is arranged perpendicular to the roller 61, and two inclined surfaces 63 are provided on the outer side of the fixed plate 62, and the two inclined surfaces 63 are symmetrically arranged with the symmetry plane of the fixed plate 62; a limiting ring 64 is provided at the end of the inclined surface 63 away from the roller 61, and the diameter of the limiting ring 64 is greater than the contact width between the inclined surface 63 and the limiting ring 64; that is, the cross-section of the two inclined surfaces 63 is trapezoidal, then the diameter of the limiting ring 64 is greater than the small bottom of the trapezoid, and is connected to the small bottom at the same time; the anti-slip sleeve 65 is supported by rubber and is fully included in the setting of the limiting ring 64 and the inclined surface 63.

[0039] By setting the inclined surface 63, it is ensured that during the extension process of the second support rod 4 and the third support rod 5, the force at the effective contact point between the fixed plate 62 and the curved side top plate 1 is always directed toward the inclined surface 63, or the angle with the inclined surface 63 will not be less than 45 degrees, thereby ensuring the effective force of the roller 6 and improving its service life. The purpose of the additional limiting ring 64 is also to this. At the same time, the limiting ring ensures that the protective cover will not fall off when it is squeezed, because there is an angle between the limiting ring 64 and the inclined surface 63. When subjected to pressure from the curved side top plate 1, the anti-slip cover 65 will be squeezed within this angle to prevent slipping.

[0040] Of course, in other embodiments, only one inclined surface 63 may be used, because the upper surface will only be in contact with the curved side top plate 1 , so the lower inclined surface 63 may not be provided.

[0041] Finally, it is important to emphasize that, in this embodiment, the invention points are mainly described in detail, and no excessive explanation is given for non-invention points, which can be completed using common processes on the market, such as: rubber selection, power supply setting of the drive motor, installation method of the drive motor, installation of the hydraulic pump, etc.

[0042] Example 2

[0043] In this embodiment, the main structure is exactly the same as that of embodiment 1, with the difference being that a rotating frame is further provided. By providing the rotating frame, the main beam frame 2 is changed into a rotatable state, thereby improving the left and right swinging of the arc-shaped side top plate 1 and improving the installation range and installation efficiency.

[0044] Specifically, such as Figure 6As shown, a rotating frame is also provided, which includes: a bracket 101 and a rotating drive member; the bracket 101 is arranged between the third hydraulic rod 8 and the main beam 2, and the bracket 101 can be raised or lowered by the third hydraulic rod 8; rotating shafts 21 are provided at both ends of the main beam 2, and the rotating shafts 21 are fixed to the bracket 101 through bearings, and can be fixed by a fixed plate 22 or other means; the rotating drive member is used to drive the main beam 2 to rotate based on the bracket 101, specifically, the rotating drive member includes: a fourth hydraulic rod 106 and a fifth hydraulic rod 107, the fourth hydraulic rod 106 and the fifth hydraulic rod 107 are respectively arranged on both sides of the main beam 2, the movable end of the fourth hydraulic rod 106 is hinged to the fixed end of the first hydraulic rod, the fixed end of the fourth hydraulic rod 106 is hinged to the bracket 101, the movable end of the fifth hydraulic rod 107 is hinged to the fixed end of the second hydraulic rod, and the fixed end of the fifth hydraulic rod 107 is hinged to the bracket 101. The main beam 2 is rotated in one direction by extending the fourth hydraulic rod 106 and shortening the fifth hydraulic rod 107, and is rotated in the other direction by shortening the fifth hydraulic rod 107 and extending the fourth hydraulic rod 106; the support rods are rotated by rotating the main beam 2, thereby expanding the paving area.

[0045] In this embodiment, a method for laying a curved side roof 1 of a tunnel is also provided, comprising the following steps:

[0046] S1: Calculate the curved side roof 1 according to the tunnel design standard, and transport the tunnel curved side roof 1 laying device into the tunnel by a mobile trolley.

[0047] S2: Adjust the extension length of the first hydraulic rod and the second hydraulic rod so that the rollers 6 on the first support rod 3, the second support rod 4 and the third support rod 5 all contact the inner side of the curved side top plate 1; tie the pull rope on the curved side top plate 1; at this time, the third hydraulic rod 8 should be retracted to lower the height of the entire equipment.

[0048] S3: Drive the first motor to drive the roller 6 to rotate, and at the same time raise the third hydraulic rod 8 from the inside to the outside of the tunnel in sequence, and then manually assist in pulling the pull rope to transport the curved side top plate 1 to the appropriate position; it should be noted here that the purpose of raising the third hydraulic rod 8 from the inside to the outside is to construct an inclined plane 63, so that the two actions of raising the curved side top plate 1 and entering the tunnel can be carried out simultaneously, which greatly improves the work efficiency. It should also be emphasized that the purpose of manually pulling the pull rope is to assist traction, which mainly serves the purpose of monitoring rather than dragging. The transportation still depends on the roller 6; it should also be emphasized that the movable end of the third hydraulic rod 8 is hinged, and the fixed end is also hinged to ensure that they will not affect each other when they are raised in sequence.

[0049] S4: After the curved side roof plate 1 is moved into place, the fourth hydraulic rod 106 and the fifth hydraulic rod 107 are driven to swing left and right to lay the curved side roof plate 1, and then the gap between the curved side roof plate 1 and the tunnel is filled with cement.

[0050] After the installation is complete, reset it and repeat the process.

[0051] Example 3

[0052] In this embodiment, the main structure is the same as that of embodiment 2, except that Figure 5 As shown, the rotating drive member is different. In this embodiment, an external gear 102 is provided on the outer side of the main beam 2, and the rotating drive member includes: a first gear 103 and a second gear 104 arranged on the bracket 101, the first gear 103 and the second gear 104 are respectively engaged with the external gear 102 and are arranged on both sides of the main beam 2; a second drive motor 105, the second drive motor 105 is arranged on the bracket 101 and drives the first gear 103 to rotate; the first gear 103 is driven to rotate by the second drive motor 105, and the first gear 103 drives the main beam 2 to rotate, thereby realizing the swing of the support rod.

[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
