Description

Technical Field

[0001] This utility model relates to the field of tunnel support structure technology, and in particular to a tunnel support structure. Background Technology

[0002] Tunnels are generally passageways that run through mountains. They are widely used for vehicle passageways and water supply and drainage channels in water conservancy projects.

[0035] Example 1

[0036] Reference Figure 1-4 A tunnel support structure includes a base 1, a threaded sleeve 2, and a threaded rod 3. The threaded sleeve 2 is fixedly installed on the top of the base 1, and the outer side of the threaded rod 3 is threadedly connected to the inner wall of the threaded sleeve 2. The tunnel support structure also includes...

[0037] The bonding mechanism and the control mechanism are combined. There are two sets of bonding mechanisms and four sets of control mechanisms.

[0038] The support mechanism includes: a base plate 4 and a top frame 5;

[0039] The base plate 4 is fixedly installed on the top of the threaded rod 3, and the top frame 5 is fixedly installed on the top of the base plate 4.

[0040] With the above structure: by setting up a support mechanism including a base plate 4 connected to the top of the threaded rod 3, and a top frame 5 installed above the base plate 4 to provide a support surface, the threaded rod 3 and the threaded sleeve 2 cooperate to rotate to achieve overall height adjustment. Two sets of fitting mechanisms and four sets of control mechanisms work together to enable the support structure to flexibly adapt to different heights and contours of the tunnel, solving the problem of inconvenient adjustment and poor adaptability of traditional support structures, and improving practicality and ease of operation.

[0041] To achieve adjustment of the angle of the bonding plate 6, the bonding mechanism includes: the bonding plate 6, the connecting rod 7, and the sliding block 8;

[0042] The bonding plate 6 is rotatably connected to the top frame 5, the connecting rod 7 is rotatably connected to the bonding plate 6, and the connecting rod 7 is rotatably connected to the sliding block 8. The sliding block 8 is slidably connected to the top of the bottom plate 4. The bonding mechanism includes the bonding plate 6 rotatably connected to the top frame 5, the connecting rod 7 and the sliding block 8 linked together. By moving the sliding block 8 on the bottom plate 4, the connecting rod 7 pushes and pulls the bonding plate 6, changing its tilt angle, so that the bonding plate 6 can tightly fit the tunnel inner wall with different inclination angles, providing uniform support force and enhancing support stability.

[0043] To support the bonding plate 6, the control mechanism includes: a mating rod 9, a fixing rod 10, and a control sleeve 11;

[0044] The mating rod 9 is fixedly connected to the sliding block 8, and the fixing rod 10 is fixedly installed on the top of the base plate 4. The control sleeve 11 is slidably sleeved on the outside of the mating rod 9. The control sleeve 11 cooperates with the fixing rod 10. The control mechanism includes the mating rod 9 connecting to the sliding block 8, the fixing rod 10 fixing the base plate 4, the control sleeve 11 slidably sleeved on the mating rod 9 and connected to the sliding block 8 through the spring 12, and the bottom positioning block of the control sleeve 11 engaging with the positioning groove of the fixing rod 10. By moving the control sleeve 11 to release the lock, the position of the sliding block 8 can be adjusted. After locking, it is firmly fixed, realizing precise control and reliable maintenance of the angle of the bonding plate 6, ensuring the support effect.

[0045] To facilitate the installation of the sliding block 8, the top of the base plate 4 is provided with four mounting grooves arranged in a matrix. The bottom of the sliding block 8 is slidably connected to the inner wall of the mounting groove. The matrix mounting grooves on the top of the base plate 4 provide multi-directional precise guidance for the movement of the sliding block 8, ensuring smooth and accurate adjustment of the angle of the bonding plate 6.

[0046] In order to reset the control sleeve 11, a spring 12 is fixedly installed on the control sleeve 11. The spring 12 is fixedly connected to the sliding block 8. The spring 12 on the control sleeve 11 connects to the sliding block 8. The spring 12 provides a continuous thrust so that the positioning block of the control sleeve 11 can automatically press against the fixed rod 10 after unlocking, which facilitates quick engagement and locking and enhances the ease of operation.

[0047] In order to position the sliding block 8, the top of the fixed rod 10 is provided with equally spaced positioning grooves, and the bottom of the control sleeve 11 is fixedly installed with a positioning block. The bottom of the positioning block slides in contact with the inner wall of the positioning groove. The top of the fixed rod 10 is provided with equally spaced positioning grooves that slide in contact with the bottom positioning block of the control sleeve 11. The positioning block can be reliably inserted into the selected positioning groove, providing multiple stable locking positions for the sliding block 8 to adapt to different support angle requirements.

[0048] In order to enable the rotation of the base plate 4, a handle 13 is fixedly installed on the bottom of the base plate 4. The handle 13 installed on the bottom of the base plate 4 provides a convenient force application point for adjusting the overall height of the rotating threaded rod 3, which simplifies the operation and saves time and effort.

[0049] The working principle of this utility model is as follows: A support mechanism is set up, including a base plate 4 connected to the top of a threaded rod 3. A top frame 5 is installed above the base plate 4 to provide a support surface. The threaded rod 3 and the threaded sleeve 2 cooperate to rotate and achieve overall height adjustment. Two sets of bonding mechanisms and four sets of control mechanisms work together. When it is necessary to adjust the angle of the two bonding plates 6, it is only necessary to pull the two adjacent control sleeves 11 away from each other and disengage them from the two fixed rods 10. This unlocks the sliding block 8 in the bonding mechanism. The bonding mechanism includes the bonding plates 6 rotatably connected to the top frame 5. The connecting rod 7 and the sliding block 8 are linked. By moving the sliding block 8 on the base plate 4, the connecting rod 7 pushes and pulls the bonding plates 6, changing their tilt angle. The bonding plate 6 can fit tightly against the tunnel wall at different inclination angles, providing uniform support and enhancing support stability. This allows the support structure to flexibly adapt to different tunnel heights and contours, solving the problems of inconvenient adjustment and poor adaptability of traditional support structures. It improves practicality and ease of operation. After adjustment, the control sleeve 11 is released, and the sliding sleeve is reset by the spring 12, automatically engaging with the fixed rod 10. The top of the fixed rod 10 has equidistant positioning grooves that slide in contact with the positioning block at the bottom of the control sleeve 11. The positioning block reliably engages with the selected positioning groove, providing multiple stable locking positions for the sliding block 8, adapting to different support angle requirements, ensuring support effect, and being quick and convenient.
