Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering construction and maintenance technology, and in particular to a device for reinforcing and strengthening tunnel lining. Background Technology

[0002] With the rapid development of transportation infrastructure construction, tunnel engineering is increasingly widely used in railways, highways, and urban rail transit. However, due to factors such as complex geological conditions, groundwater erosion, repeated vehicle loads, and construction defects, tunnel linings are prone to defects such as cracks, spalling, and water leakage. Currently, tunnel lining reinforcement relies heavily on manual or semi-mechanized operations. Traditional methods have many limitations: manual operation is inefficient, labor-intensive, and it is difficult to ensure the uniformity of reinforcement force and construction accuracy; existing mechanical devices often have simple structures and poor adaptability to the complex curved surfaces of tunnel linings, easily leading to reinforcement blind spots; in addition, problems such as local stress concentration and poor bonding of reinforcement materials frequently occur during the reinforcement process, making it difficult to maintain the reinforcement effect and requiring frequent maintenance. Therefore, a tunnel lining reinforcement device is proposed. Utility Model Content

[0005] A fixing component, installed on the support component, is used to adapt to and adjust the working posture and position of the device;

[0006] in:

[0007] The base has a support assembly at its top, which includes a vertical support member. A multi-stage telescopic rod is installed at the top of the vertical support member. A sliding member is fixedly connected to the output end of the multi-stage telescopic rod. The base has a guide rail, and the sliding member is slidably adapted to the guide rail.

[0008] As a further preferred embodiment of this technical solution: the sliding member is equipped with a transmission member, the outer side of the transmission member is provided with a first adapter block, the side of the first adapter block away from the transmission member is hinged with a connecting rod, the side of the connecting rod away from the first adapter block is hinged with a second adapter block, and the side of the second adapter block away from the connecting rod is equipped with a reinforcing plate.

[0010] As a further preferred embodiment of this technical solution: the fixing component includes a fixing block, one side of the fixing block is mounted on a reinforcing plate, a reinforcing rod is hinged to the side of the fixing block away from the reinforcing plate, a transition groove is hinged to the side of the reinforcing rod away from the fixing block, a threaded rod is provided on the transition groove, a rotating rod is installed on one side of the threaded rod, a cylindrical component is connected to the side of the threaded rod away from the rotating rod, and a limit component is installed on the cylindrical component.

[0011] As a further preferred embodiment of this technical solution: a limiting block is installed in the middle of the reinforcing rod, an auxiliary component is hinged to the side of the limiting block away from the reinforcing rod, and a second transition groove is hinged to the side of the auxiliary component away from the limiting block, with the cylindrical component passing through the second transition groove.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] I. This utility model employs an electric or hydraulic multi-stage telescopic rod and sliding components in conjunction with a guide rail to achieve rapid and precise positioning of the reinforcing plate in three-dimensional space. Five sets of reinforcing plates constitute a multi-station operation unit, with a cross-encircling layout, enabling simultaneous reinforcement of multiple areas of the lining. Compared to traditional single-station operations, this increases efficiency by over 50% and significantly shortens the construction cycle. The chain drive structure evenly distributes the thrust of the telescopic rod to the reinforcing plate, avoiding localized stress concentration in the lining. The diamond composite wear-resistant protrusions on both sides of the reinforcing plate, which are sandblasted and roughened, significantly enhance the interlocking force with the lining through micro-mechanical interlocking. Combined with constant pressure bonding, this effectively prevents the reinforcing material from falling off, increasing the load-bearing capacity of the lining structure by more than 30% and significantly extending the service life of the tunnel.

[0017] II. This utility model achieves efficient and precise operation: the fixing component achieves fine-tuning of the reinforcement plate's posture through threaded rod-cylindrical transmission, combined with the multi-directional degrees of freedom of the hinge structure, which can adaptively conform to the complex shapes of the tunnel lining, such as curved and concave surfaces; the triangular stabilizing structure enhances the torsional resistance of the reinforcement rod, ensuring that the reinforcement plate is always perpendicular to the lining surface, and can still guarantee reinforcement accuracy in irregular cross-sections or defective areas, while the limiting sleeve provides stable guidance for the transmission components, avoiding jamming and offset during force transmission; each hinge point and transmission component adopts redundant design, and limiting structures are set in key parts, which can still maintain stable operation in harsh environments such as tunnel vibration and humidity, reduce equipment failure rate, and extend maintenance cycle by more than 40%.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1-3 As shown, this embodiment of the utility model provides a device for reinforcing and strengthening tunnel linings, including a base 1 and a support assembly 15 installed on the base 1, and further including:

[0029] Fixed component 26 is installed on support component 15 and is used to adapt to the working posture and position of the adjustment device;

[0030] in:

[0031] The top of the base 1 is provided with a support component 15, which includes a vertical support member 2. A multi-stage telescopic rod 3 is installed at the top of the vertical support member 2. A sliding member 5 is fixedly connected to the output end of the multi-stage telescopic rod 3. The base 1 is provided with a guide rail 4, and the sliding member 5 is slidably adapted to the guide rail 4.

[0032] In this embodiment, the present invention, when in operation, adjusts the position and posture of the working end through the sliding member 5 and the telescopic rod, so that the pasting tool can accurately fit the lining, ensuring the flatness and adhesion of the carbon fiber cloth.

[0033] Specifically, the sliding member 5 is equipped with a transmission member 7, and a first adapter block 8 is provided on the outer side of the transmission member 7. A connecting rod 9 is hinged to the side of the first adapter block 8 away from the transmission member 7. A second adapter block 10 is hinged to the side of the connecting rod 9 away from the first adapter block 8. A reinforcing plate 11 is installed on the side of the second adapter block 10 away from the connecting rod 9.

[0034] In this embodiment, when the present invention is in operation: the transmission component 7, the adapter block, the connecting rod 9 and the reinforcing plate 11 form a chain transmission structure. The force output by the multi-stage telescopic rod 3 is transmitted to the transmission component 7 through the sliding component 5, and then evenly distributed to the reinforcing plate 11 through the hinged adapter block and connecting rod 9. This allows the reinforcing plate 11 to apply the reinforcing force evenly to the lining surface, preventing local stress concentration from causing lining damage, and improving the stability of the reinforcement.

[0035] Specifically, a limiting sleeve 14 is sleeved on the outer side of the transmission component 7. One side of the limiting sleeve 14 is fixedly connected to the base 1. Several grooves 12 and protrusions 13 are provided on both sides of the reinforcing plate 11. The transmission component 7 is provided with a receiving groove 6. The vertical support component 2 is located in the receiving groove 6. Five of each of the first adapter block 8, the second adapter block 10, and the reinforcing plate 11 are provided.

[0036] In this embodiment, the present invention is specifically designed to work with five of the following components: one of the transition blocks 8, one of the transition blocks 10, and five of the reinforcing plates 11, forming a multi-station work unit. During tunnel lining reinforcement work, multiple reinforcing plates 11 can simultaneously reinforce different areas, greatly improving work efficiency.

[0037] Specifically, the fixing component 26 includes a fixing block 16. One side of the fixing block 16 is mounted on the reinforcing plate 11. A reinforcing rod 17 is hinged to the side of the fixing block 16 away from the reinforcing plate 11. A transition groove 18 is hinged to the side of the reinforcing rod 17 away from the fixing block 16. A threaded rod 22 is provided on the transition groove 18. A rotating rod 23 is mounted on one side of the threaded rod 22. A cylindrical member 24 is connected to the side of the threaded rod 22 away from the rotating rod 23. A limit member 25 is mounted on the cylindrical member 24.

[0038] In this embodiment, the present invention operates as follows: the rotating rod 23 drives the threaded rod 22 to rotate, the cylindrical part 24 moves along the axial direction of the threaded rod 22, and the limiting part 25 adjusts the hinge angle of the reinforcing rod 17, thereby controlling the displacement and pressure output of the reinforcing plate 11.

[0039] Specifically, a limiting block 19 is installed in the middle of the reinforcing rod 17. An auxiliary component 20 is hinged to the side of the limiting block 19 away from the reinforcing rod 17. A transition groove 21 is hinged to the side of the auxiliary component 20 away from the limiting block 19. A cylindrical component 24 passes through the transition groove 21.

[0040] In this embodiment, the auxiliary component 20, the limiting block 19, and the transition groove 21 form a triangular stable structure during operation, which enhances the anti-torsion and anti-eccentricity of the reinforcing rod 17 in three-dimensional space. When working on irregular curved surfaces of tunnel lining, the posture can be adaptively adjusted to ensure that the reinforcing plate 11 is always perpendicular to the lining surface, avoiding bending or displacement of the reinforcing rod 17 due to lateral force, and ensuring the accuracy of the reinforcement operation.

[0041] Specifically, the two sets of reinforcing plates 11 are arranged in a cross pattern to form an encircling reinforcement working space that adapts to the curved surface structure of the tunnel lining, and the diameter of the limiting sleeve 14 is larger than the diameter of the transmission component 7.

[0042] In this embodiment, when the present invention is in operation: the diameter of the limiting sleeve 14 is larger than that of the transmission component 7, which not only provides sufficient sliding space for the transmission component 7 to avoid jamming due to excessive frictional resistance, but also forms a stable guide through clearance fit.

[0043] Specifically, the protrusion 13 is made of diamond composite wear-resistant material and its surface is roughened by sandblasting to enhance the mechanical interlocking force and reinforcement effect with the tunnel lining.

[0044] In this embodiment, the present invention, when in operation, involves surface sandblasting and roughening treatment to significantly increase the contact surface area between the protrusion 13 and the lining, forming a microscopic mechanical interlocking structure. Combined with the applied reinforcing force, this significantly enhances the interlocking force between the two, ensuring that the reinforcing plate 11 is tightly attached to the lining, preventing the reinforcing material from falling off, and effectively improving the long-term stability of the tunnel structure.

[0045] Specifically, the multi-stage telescopic rod 3 is an electric telescopic rod or a hydraulic telescopic rod, with a stroke control accuracy of ≤±0.5mm and a maximum output thrust of ≥50kN.

[0046] In this embodiment, the specific utility model, during operation, can precisely adjust the distance between the reinforcing plate 11 and the lining by controlling the stroke of the multi-stage telescopic rod 3, ensuring that the reinforcing material is bonded with constant pressure, and avoiding problems such as hollowing and wrinkling caused by uneven pressure.

[0047] Working principle: First, the device is placed on the support frame. Through the extension and retraction of the multi-stage telescopic rod 3 and the displacement of the sliding member 5 on the guide rail 4, the three-dimensional spatial position and posture of the reinforcing plate 11 are precisely adjusted to fit the curved surface of the tunnel lining. Then, the rotating rod 23 in the fixed component 26 drives the threaded rod 22 to rotate, which drives the cylindrical member 24 to move axially and adjust the hinge angle of the reinforcing rod 17. During operation, the thrust output by the multi-stage telescopic rod 3 is transmitted to the transmission component 7 through the sliding member 5, and then through the chain consisting of the first adapter block 8, the connecting rod 9, and the second adapter block 10. The transmission structure evenly distributes the force to five sets of cross-laid reinforcing plates 11, forming an encircling reinforcement space. The limiting sleeve 14 provides stable guidance for the transmission component 7, preventing force transmission deviation. The diamond composite wear-resistant protrusions 13 on both sides of the reinforcing plate 11, which are roughened by sandblasting, tightly engage with the lining surface to ensure that the reinforcing plate 11 is firmly attached. At the same time, the limiting block 19, auxiliary component 20 and the transition groove 21 in the middle of the reinforcing rod 17 form a triangular stable structure to ensure that the reinforcing plate 11 is always perpendicular to the lining surface, thereby improving the efficiency and quality of tunnel lining reinforcement.

[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
