Detailed Description

The following description of the preferred embodiments of the present invention is provided in conjunction with the accompanying drawings and will be described in detail.

As shown in fig. 1, an embodiment of the present invention provides a suspension connection 100 for mounting a module 200 to a tunnel roof. Specifically, an embedded steel plate 300 is arranged on the top of the tunnel, a plurality of H-shaped steels 400 extending in the vertical direction (i.e., the Z direction) are arranged on the embedded steel plate 300, two connection points are arranged on the module 200, and are sequentially arranged in the length direction (i.e., the X direction) of the module 200, two lifting lugs 201 are arranged at each connection point in the Y direction (i.e., the direction perpendicular to the X direction on the horizontal plane), and the suspension connection mechanism 100 is fixedly connected with the lifting lugs 201, so that the module 200 is fixed on the suspension connection mechanism 100; the suspension connection mechanism 100 is also located between the two H-shaped steels 400 and is fixedly connected with the two H-shaped steels 400, thereby suspending the module 200 on the top of the tunnel.

As shown in fig. 2, when the tunnel roof vibrates, the vibration is transmitted to the H-beam 400 through the embedded steel plate 300, then transmitted to the suspension link 100 from the H-beam 400, and then transmitted to the module 200 from the suspension link 100, resulting in instability of the module 200, and since the H-beam 400 is welded to the embedded steel plate 300, they are supported by the suspension link 100 and the module 200 as a whole with the tunnel roof, so that the stability of the module 200 is determined by the suspension link 100.

As shown in fig. 3 and 4, the suspension connection mechanism 100 includes a cross beam 110 and a base 120, a slide table seat 121 fixed in position relative to the base 120 is disposed on the base 120, for example, the slide table seat 121 may be integrally formed with the base 120 to fix the relative position of the two, a sliding table 130 is slidably disposed on the slide table seat 121, and the cross beam 110 is disposed on the sliding table 130; as shown in fig. 5, 6 and 7, the upper surface of the slide table base 121 is an inclined surface whose height (i.e., Z-direction position) changes uniformly along the X-direction, that is, the upper surface is inclined to the horizontal plane and has different heights along the Z-direction of the X-direction, the lower surface of the slide table 130 and the upper surface of the slide table base 121 are matched with each other, and both together form a contact surface between the slide table base 121 and the slide table 130; the sliding table 130 can slide on the sliding table base 121 along the X direction and the Y direction, when the sliding table 130 slides along the X direction, because the contact surface of the sliding table 130 and the sliding table base 121 is an inclined surface, the Z-direction height of the sliding table 130 can also change when the sliding table slides along the X direction, that is, the X-direction position and the Z-direction position of the sliding table 130 can be simultaneously adjusted when the sliding table 130 slides along the Y direction, and the Y-direction position of the sliding table 130 relative to the base 120 can be adjusted when the sliding table 130 slides along the Y direction. When the installation, the base 120 is fixed on the H-beam 400, and the module 200 is fixed on the beam 110, so that the module 200 can be suspended on the top of the tunnel, and the positions of the beam 110 and the module 200 can be adjusted by sliding the sliding table 130, thereby facilitating the installation and compensating the settlement by adjusting the position in the Z direction.

As shown in fig. 5 to 7, the sliding table 130 is provided with a first kidney-shaped hole 131 and a second kidney-shaped hole 132, the sliding table base 121 is provided with a hole 121a (which is an unthreaded hole), the first screw 171 sequentially passes through a threaded hole (not shown) in the cross beam 110 and the first kidney-shaped hole 131 of the sliding table 130 and then is inserted into the hole 121a, so that the cross beam 110 and the sliding table base 121 are fixedly connected, and the sliding table 130 is switchable between a slidable state and a fixed state within a movement range defined by the first screw 171 and the first kidney-shaped hole 131. Bolts 172 (shown in fig. 3 and 4) are inserted into threaded holes (not shown) on the slide base 121 after passing through holes (which are unthreaded holes and not shown) on the cross beam 110 and the second kidney-shaped holes 132 in sequence, so that the cross beam 110 and the slide base 130 are fixedly connected. During installation, the first screw 171 and the bolt 172 may be pre-installed, that is, the first screw 171 passes through the threaded hole of the cross beam 110 and the first kidney-shaped hole 131 and then is inserted into the hole 121a, but the first screw 171 and the threaded hole of the cross beam 110 are not completely locked, the bolt 172 passes through the cross beam 110 and the second kidney-shaped hole 132 and then is inserted into the threaded hole of the slide pedestal 121, but the bolt 172 and the threaded hole of the slide pedestal 121 are not completely locked; because the diameters of the first screw 171 and the bolt 172 are smaller than those of the first kidney-shaped hole 131 and the second kidney-shaped hole 132, the sliding table 130 is in a slidable state and can move relative to the first screw 171 and the bolt 172, the threaded hole in the cross beam 110, which is matched with the first screw 171, and the unthreaded hole in the cross beam 172, which is matched with the bolt 172, are both common round holes, and the hole 121a is also a common round hole, so that relative movement cannot occur between the cross beam 110 and the first screw 171 and between the base 120 and the first screw 171, and thus, when the sliding table 130 moves relative to the first screw 171 and the bolt 172, relative movement also occurs relative to the cross beam 110 and the base 120 (including the sliding table seat 121), and the movement direction is the extending direction of the first kidney-shaped hole 131 and the second kidney-shaped hole 132, and in this embodiment, is the X direction; when the sliding table 130 moves in the X direction under the action of an external force, the Z-direction position of the sliding table 130 changes because the contact surface between the sliding table 130 and the sliding table base 121 is an inclined surface, and the Z-direction position of the cross beam 110 changes along with the sliding table 130, so that the Z-direction position of the module 200 is adjusted to perform settlement compensation. After the adjustment, the first screw 171 and the bolt 172 can be tightened to lock the first screw 171 with the threaded hole on the cross beam 110, and the bolt 172 with the threaded hole on the slide base 121, so that the cross beam 110, the slide table 130 and the slide base 121 are fixed, the slide table 130 is in a fixed state, and the slide table 130 can not slide any more. In this embodiment, there are two first kidney-shaped holes 131 respectively located at two sides of the sliding table 130 in the Y direction, and four second kidney-shaped holes 132 respectively located at four corners of the sliding table 130. The first and second waist- shaped holes 131 and 132 may be equal in size.

It can be understood that the amount of movement of the Z-direction position of the slide table 130 is determined by the amount of movement of the X-direction position and the inclination angle of the upper surface of the slide table base 121, so that the movement range of the Z-direction position can be changed by adjusting the size of the inclination angle and the movement range of the X-direction position, and since the first screw 171 is always kept still when the slide table 130 moves along the X direction, the length of the first kidney-shaped hole 131 along the X direction is the movement range of the slide table 130. For example, in an exemplary embodiment, the inclination angle is 8 °, the length of the first kidney-shaped hole 131 is 55mm, and the maximum distance that the sliding table 130 can move in the Z direction is 55 × tan8 ° ≈ 7.7mm, i.e., the sliding table 130 can realize Z-direction height adjustment within 7.7 mm.

A slight gap (e.g., 2 mm) may exist between the first screw 171 and the first kidney-shaped hole 131 in the Y direction, so that the Y-direction position of the slide table 130 may be finely adjusted by the first Y-direction adjusting bolt 143 even after the first screw 171 and the bolt 172 are pre-installed.

The first bracket 141 may be a U-shaped frame such that the first bracket 141 is engaged with both Y-directional sidewalls of the slide table 130 to receive portions of the X-directional side and both Y-directional sidewalls of the slide table 130 therein. In this embodiment, two first adjusting assemblies 140 may be disposed on two sides of the sliding table 130 in the X direction, two first brackets 141 are respectively engaged with four side walls of the sliding table 130, and the sliding table 130 moves between the two U-shaped brackets.
