Description

Technical Field

[0001] The utility model relates to the technical field of tunnel lining repair, in particular to a temporary supporting device for a tunnel reinforcement structure. Background Art

[0002] After being put into operation, completed tunnels may develop various degrees of defects, with lining cracking, voids, block loss, and water leakage being the most common. Tunnel defects can reduce the mechanical properties of the tunnel structure, affecting the stability of the tunnel lining, shortening its service life, and in severe cases, endangering traffic safety. Therefore, tunnel lining repairs typically involve attaching steel strips to the lining, forming a ring-shaped structure attached to the lining and anchored with anchor rods. To apply pressure to the steel strips and ensure rapid attachment to the lining, temporary support devices are used to support them. These devices are then removed upon completion.

[0003] However, existing support devices typically utilize a simple support rod structure, requiring the rod to be tapped during installation and removal to engage or disengage the steel belt between the platform. This presents the following drawbacks: 1. The tapping process can easily scratch the steel belt and / or cause wear on the end of the support rod; 2. The ring-shaped steel belt reduces the contact area between the steel belt and the end of the support rod; and 3. The support rod is difficult to securely tilt to the platform, resulting in the steel belt being supported only in a vertical position, limiting its practicality. Utility Model Content

[0023] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] In the embodiment of the present utility model, Figure 1-Figure 3 As shown, the temporary support device of the tunnel reinforcement structure includes: a base 1, a drive assembly 2 and a support assembly 3; the drive assembly 2 includes a first drive part 201 and a second drive part 202 that are rotatably connected, and the first drive part 201 is movably provided on the base 1, and is used to drive the second drive part 202 to rotate forward and reverse relative to the first drive part 201; the support assembly 3 includes a plurality of first telescopic rods 301 and a plurality of second telescopic rods 302, and the first telescopic rods 301 and the second telescopic rods 302 are independently provided on the first drive part 201 and the second drive part 202, and the first telescopic rod 301 extends in the up and down direction, and the second telescopic rod 302 rotates with the second drive part 202, so that the second telescopic rod 302 is arranged parallel to or inclined relative to the first telescopic rod 301.

[0025] Specifically, in the embodiment of the present utility model, the base 1 is used to be installed on a platform (the platform can be a lifting platform or other construction platform for the base 1 to be installed); Figure 1 、 Figure 2 As shown, the base 1 in this embodiment is an I-shaped base 1 constructed from multiple fixing rods. Each fixing rod is enlarged and thickened to enhance the structural strength and stability of the base 1. Of course, the fixing rods can be detachably connected or integrally formed. Furthermore, the reinforcement rods in contact with the platform are provided with multiple reinforcement seats to further enhance the stability of the base 1.

[0026] In the embodiment of the present invention, the driving component 2 is defined as a first driving part 201 and a second driving part 202 that rotate relative to each other. The first driving part 201 can move relative to the base 1, thereby driving the second driving part 202 to rotate forward and reverse, so as to change the angle between the two driving parts.

[0027] In an embodiment of the present invention, a first telescopic rod 301 and a second telescopic rod 302 are respectively provided at the first drive unit 201 and the second drive unit 202. The two telescopic rods are independent and stationary relative to their respective drive units. Specifically, the second drive unit 202 can link the second telescopic rod 302 to rotate forward and reverse relative to the first telescopic rod 301, thereby enabling the first telescopic rod 301 and the second telescopic rod 302 to be arranged parallel or at an angle. Since the first telescopic rod 301 is arranged in the vertical direction, it is used to vertically support the steel belt. When the two telescopic rods are arranged parallel, the two drive blocks are arranged in the front-to-back direction, so the two telescopic rods can support the steel belt in the front-to-back direction. Conversely, when the two telescopic rods are arranged at an angle, the two support rods can be tangent to the steel belt and support it at different positions on the steel belt, thereby applying pressure and supporting it in different directions. Furthermore, the rotating second telescopic rod 302 can adapt to the endless steel belt and rotate according to the shape of the steel belt, thereby improving the versatility of the present device. Of course, the first telescopic rod 301 and the second telescopic rod 302 can be set to multiple, used to support the steel belt from different directions, increasing the support points of the device; furthermore, the two telescopic rods are hydraulically or electrically retractable, so that they can be retracted and retracted according to the distance from the steel belt, and can replace the traditional knocking installation and disassembly method, with a high degree of automation, saving installation and disassembly time.

[0028] In this embodiment, the first driving part 201 and the second driving part 202 are arranged in a one-to-one correspondence with the first telescopic rod 301 and the second telescopic rod 302, so that the second driving part 202 can link the second telescopic rod 302 to rotate forward and reverse relative to the first telescopic rod 301, so that the two telescopic rods are arranged in parallel or at an angle, so as to support the steel belt from different directions, increase the supporting area with the steel belt, and enable the steel belt to be firmly fixed to the lining; in addition, the second telescopic rod 302 is installed on the base 1 through the two driving parts, and the telescopic rod is separated from the platform by the two driving parts and the base 1. Even if the second telescopic rod 302 is installed at an angle, it can still be in full contact with the steel belt, which is convenient for installation and disassembly; at the same time, the use of the telescopic rod can make it easier to tighten or release the steel belt by the telescopic rod itself when aligning the steel belt, which makes operation easier.

[0029] like Figure 3As shown, in one embodiment, the first driving portion 201 slides back and forth on the base 1 and is provided with a guide protrusion 203. The second driving portion 202 is provided with an arcuate guide groove 204 along its rotation path, for the guide protrusion 203 to extend into the arcuate guide groove 204. Specifically, in order to drive the second driving portion 202 to rotate forward and reverse, this embodiment forms a guide protrusion 203 integrally on the first driving portion 201 and provides an arcuate guide groove 204 on the second driving portion 202, so that the guide protrusion 203 extends into the arcuate guide groove 204. During the reciprocating sliding process of the first driving portion 201, the second driving portion 202 can be pulled to rotate by the cooperation of the guide protrusion 203 and the arcuate guide groove 204. At the same time, the arcuate guide groove 204 is an arcuate structure, which has the same rotation path as the second driving portion 202 (arranged concentrically), so as to easily define the rotation arc of the second driving portion 202.

[0030] Furthermore, if Figure 3 As shown, in one embodiment, the base 1 is detachably provided with a slide 4, and the first driving part 201 is slidably provided on the slide 4. Specifically, in order to enable the first driving part 201 to slide back and forth on the base 1, this embodiment provides a slide 4 on the base 1, and the slide 4 and the base 1 are respectively provided with matching slide grooves and sliders. Under the action of external force, the slider can slide back and forth in the slide groove to link the first driving part 201 to slide back and forth. Figure 3 As shown, the second driving portion 202 is rotatably provided on the slide seat 4 and forms a hinge point, so that the second driving portion 202 can rotate around the hinge point under the guidance of the guide protrusion 203 and the arc-shaped guide groove 204.

[0031] Preferably, in order to facilitate the storage and folding of the device, a detachable connection method is adopted between the base 1 and the slide 4 in this embodiment. Specifically, the base 1 is connected to the base 1 through an installation component 5, and the installation component 5 includes a first clamping block 501 and a second clamping block 502 arranged at intervals, and a locking screw 503 threadedly connected to the first clamping block 501 and the second clamping block 502. The first clamping block 501 and the second clamping block 502 are respectively located at the opposite end surfaces of the base 1 and clamp the base 1 therebetween. By screwing the locking screw 503 in or out, the spacing between the two clamping blocks can be changed, thereby clamping or releasing the base 1 therebetween, so that the slide 4 can be detachably installed on the base 1. A locking nut is provided on the outer surface of the locking screw 503 to limit its position.

[0032] like Figure 1 、 Figure 3As shown, in one embodiment, the slide 4 is provided with a threaded rod 6, which passes through the first drive portion 201, and whose axis extends in the sliding direction of the first drive portion 201. Specifically, in order to drive the first drive portion 201 to slide back and forth on the slide 4, this embodiment provides a threaded rod 6, so that the first drive portion 201 is sleeved on the threaded rod 6, and the first drive portion 201 is moved back and forth along a straight line through the rotation of the threaded rod 6. In other words, the threaded rod 6 and the first drive portion 201 are equivalent to the screw and slide 4 used in conjunction; alternatively, the first drive portion 201 can be driven by a cylinder provided on the base 1, and the cylinder is extended and retracted to drive the first drive portion 201 to slide.

[0033] like Figure 3 As shown, in one embodiment, a spring 7 is disposed on the outer sleeve of the threaded rod 6, with both ends of the spring 7 respectively contacting the first drive unit 201 and the slide 4. Specifically, to provide a shock-absorbing or buffering effect, this embodiment disposes a spring 7 between the first drive unit 201 and the slide 4. The spring 7 is sleeved on the threaded rod 6, allowing the spring 7 to be stretched or compressed during the movement of the first drive unit 201. This spring 7 is a shock-absorbing spring 7.

[0034] like Figure 3 As shown, in one embodiment, the first drive unit 201 and / or the second drive unit 202 are provided with a plurality of connecting sleeves 8, into which the first telescopic rod 301 and / or the second telescopic rod 302 are threaded. Specifically, to facilitate installation and folding and storage of the device, this embodiment provides connecting sleeves 8 on both the first drive unit 201 and the second drive unit 202, allowing each telescopic rod to be threaded into a corresponding connecting sleeve 8, thereby achieving a removable connection between the telescopic rod and the first drive unit 201. Furthermore, to enhance the versatility of the device and enable multi-directional support of the steel belt, the number of sleeves can be adjusted as needed. Furthermore, the connecting sleeves 8 provided on the first drive unit 201 allow the first telescopic rod 301 to be selectively inserted into a corresponding connecting sleeve 8, thereby reducing or preventing the first telescopic rod 301 from obstructing the rotation of the second telescopic rod 302, thereby preventing the formation of a rotational dead angle.

[0035] like Figure 1 、 Figure 2 As shown, in one embodiment, a gasket 9 is provided at the end of the first telescopic rod 301 and the end of the second telescopic rod 302 to increase the contact area and friction with the steel belt.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
