Description

Technical Field

[0001] The present invention relates to the technical field of roadbed culvert reinforcement, and in particular to a supporting and reinforcing device for a roadbed culvert and a use method thereof. Background Art

[0002] In road construction, culverts are important structures for drainage and crossing obstacles, and are widely used in high-fill roadbed sections. With the increase of service life, repeated traffic loads and the settlement and deformation of the high-fill soil itself, the culvert structure is prone to damage, especially the inner wall of the culvert is under great pressure, and cracks, deformation and even collapse often occur, which seriously affects the drainage and bearing capacity of the culvert, and thus endangers road traffic safety.

[0003] The existing culvert space is narrow. When the culvert needs to be supported and reinforced, it is difficult to transport large and heavy supporting equipment into the culvert. The narrow space limits the equipment's entry and exit and operational flexibility. Workers often can only rely on simple tools and use pure manual methods to build temporary supports. This not only consumes a lot of manpower and time, but also the support effect is uneven. It is difficult to accurately adapt to the complex inner wall curve of the culvert and cannot provide stable and reliable reinforcement force. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention proposes a support and reinforcement device for a roadbed culvert and a method of using the same to solve the above problems.

[0005] A support and reinforcement device for a roadbed culvert includes a mounting frame, a mounting plate provided on the mounting frame, a support mechanism fixedly connected to the upper surface of the mounting plate, the support mechanism including a mounting shell, support plates symmetrically provided on both sides of the mounting shell, and the symmetrical layout ensures balanced force transmission and prevents tilting of the device due to eccentric loading.

[0006] The support plates are rotatably connected to support columns on both sides. The bottom ends of the support columns are movably connected to a drive mechanism. The top ends of the support columns are fixedly connected to a curved top plate. The curved top plates of different thicknesses can be replaced to adapt to culvert top walls of different heights. The curved top plate fits the culvert curve, increasing the contact area.

[0007] Furthermore, the mounting frame serves as a core skeleton, carrying components such as the upper mounting shell, support plate, drive mechanism, and bottom hydraulic cylinder, ensuring the stability of the overall structure and preventing the device from deforming or becoming unstable when subjected to stress.

[0008] Furthermore, the driving mechanism includes a reciprocating screw arranged inside the mounting shell, the two ends of the reciprocating screw being rotatably connected to the inner wall of the mounting shell, and also includes a sliding seat, the surface of the sliding seat being provided with a positioning groove, the positioning groove being matched with the reciprocating screw thread, so that the sliding seat moves along the reciprocating screw.

[0009] Furthermore, the driving mechanism enables the support height of the curved top plate to be flexibly adjusted according to the stress and deformation conditions of the culvert at different stages, such as increase in fill height and change in foundation settlement.

[0010] Furthermore, a drive motor is used to drive the reciprocating screw rod, and then the lifting height of the arc top plate is accurately controlled through the connecting rod, ensuring that the reinforced structure is always in the best working condition and adapting to the dynamic changes of the culvert structure in real time.

[0011] Furthermore, a second sliding groove is provided on the surface of the sliding seat, and the circumferential edge of the mounting shell is slidingly matched with the second sliding groove.

[0012] Furthermore, a first sliding groove is provided on the surface of the mounting shell, the first sliding groove is matched with a sliding block, and the sliding block is provided on the inner surface of the second sliding groove.

[0013] Furthermore, it also includes a connecting rod, the two ends of which are rotatably connected to the bottom end of the support column and the surface of the sliding seat respectively.

[0014] Furthermore, either end of the reciprocating screw is connected to a driving motor for driving the reciprocating screw to rotate, and a rubber pad is provided on the top of the arc-shaped top plate to increase friction.

[0015] Furthermore, the bottom of the installation frame is equipped with moving wheels, which makes it easier to move and position the device in narrow culverts, reducing manpower handling.

[0016] Furthermore, a telescopic cylinder is installed inside the mounting frame, and an output end of the telescopic cylinder is fixedly connected to an anti-skid plate.

[0017] Furthermore, through the synergistic effect of the curved top plate on the top and the anti-skid plate on the bottom, the culvert is reinforced from top to bottom at the same time. The curved top plate fits the top of the culvert, evenly dispersing the pressure of the fill above, avoiding local stress concentration that may cause damage to the top of the culvert; the anti-skid plate enhances friction from the bottom and provides supporting reaction force, effectively resisting the vertical settlement and lateral displacement of the culvert, and comprehensively improving the bearing capacity of the culvert in a high-fill roadbed environment.

[0018] A method of use, comprising the following steps:

[0019] Initial positioning and transportation: Push the reinforcement device into the culvert through the moving wheels at the bottom and place it at the bottom center of the section to be reinforced. At this time, the curved top plate is in the low position, and a certain gap is left between the rubber pad and the top of the culvert. The hydraulic cylinder is retracted and the anti-slip plate is close to the installation plate.

[0020] Bottom fixing: Start the hydraulic cylinder to push the anti-skid plate downward to press the bottom surface of the culvert;

[0021] Top support adjustment: Start the drive motor to drive the reciprocating screw to rotate, drive the sliding seat to move toward each other along the slide groove, and at the same time push the support column upward through the connecting rod to lift the arc-shaped top plate until the outer rubber pad fits tightly against the top of the culvert;

[0022] Dynamic adjustment: control the forward and reverse rotation of the drive motor, fine-tune the height of the arc top plate, adjust the extension and contraction of the hydraulic cylinder, and optimize the contact pressure between the anti-skid plate and the bottom surface.

[0023] Compared with the prior art, this application has the following beneficial effects:

[0024] The reciprocating screw drives the sliding seat to move horizontally toward each other, pushing the connecting rod to make the support column rotate synchronously to adapt to the inclination angle of the culvert top wall, and at the same time triggering the extension of the support column to realize the vertical jacking of the curved top plate, finally achieving dynamic adaptive support under one-button operation. The contact area between the curved top plate and the rubber pad is large, so that the stress is evenly dispersed. The forward and reverse rotation of the motor automatically compensates for the fill settlement. The double slide constraint and symmetrical layout eliminate the risk of overloading, ensure the stability of the culvert, facilitate installation and commissioning, improve the reinforcement efficiency, and solve the problems of low efficiency and weak reinforcement of traditional manual reinforcement.

[0035] Example 1

[0036] like Figure 1-2 A support and reinforcement device for a roadbed culvert is described, comprising a mounting frame 1, a mounting plate 2 being provided on the mounting frame 1, a support mechanism 7 being fixedly connected to the upper surface of the mounting plate 2, the support mechanism 7 comprising a mounting shell 3, support plates 4 being symmetrically provided on both sides of the mounting shell 3, the symmetrical layout ensuring balanced force transmission and preventing tilting of the device due to eccentric loading.

[0037] The support plate 4 is rotatably connected to support columns 5 on both sides. The bottom end of the support column 5 is movably connected to a drive mechanism. The top end of the support column 5 is fixedly connected to a curved top plate 6. By changing the curved top plate 6 of different thicknesses to adapt to the culvert top wall of different heights, the curved top plate 6 conforms to the culvert surface, increasing the contact area.

[0038] The mounting frame 1 serves as the core skeleton, carrying components such as the upper mounting shell, support plate, drive mechanism, and bottom hydraulic cylinder, ensuring the stability of the overall structure and preventing the device from deformation or instability when subjected to stress.

The top ends of the support columns 5 are fixedly connected to a curved top plate 6. By replacing the curved top plates 6 with different thicknesses, the culvert top walls of different heights can be adapted. Alternatively, the support columns 5 can be replaced with retractable ones. By adjusting the retractable support columns 5, the curved top plate 6 can be made to fit the culvert surface, thereby increasing the contact area.

[0045] The mounting frame 1 serves as the core skeleton, carrying components such as the upper mounting shell, support plate, drive mechanism, and bottom hydraulic cylinder, ensuring the stability of the overall structure and preventing the device from deformation or instability when subjected to stress.

[0046] The driving mechanism includes a reciprocating screw 71 arranged inside the mounting shell 3, and the two ends of the reciprocating screw 71 are rotatably connected to the inner wall of the mounting shell 3. It also includes a sliding seat 72, and a positioning groove 14 is opened on the surface of the sliding seat 72. The positioning groove 14 is threadedly engaged with the reciprocating screw 71, so that the sliding seat 72 moves along the reciprocating screw 71.

[0047] The driving mechanism enables the support height of the curved top plate to be flexibly adjusted according to the stress and deformation conditions of the culvert at different stages, such as increase in fill height and change in foundation settlement.

[0048] The reciprocating screw is driven by a drive motor, and the lifting height of the arc top plate is precisely controlled through the connecting rod, ensuring that the reinforced structure is always in the best working condition and can adapt to the dynamic changes of the culvert structure in real time.

[0050] A first sliding groove 8 is provided on the surface of the mounting shell 3 . The first sliding groove 8 is matched with a slider 13 . The slider 13 is provided on the inner surface of the second sliding groove 15 .

[0051] It also includes a connecting rod 74, the two ends of which are rotatably connected to the bottom end of the support column 5 and the surface of the sliding seat 72 respectively.

[0052] Either end of the reciprocating screw rod 71 is connected to a driving motor 73 for driving the reciprocating screw rod 71 to rotate. A rubber pad 9 is provided on the top of the arc-shaped top plate 6 to increase friction.

[0053] The bottom of the mounting frame 1 is provided with a moving wheel 10, which facilitates the positioning of the device in a narrow culvert and reduces the need for manual handling.

[0054] A telescopic cylinder 11 is installed inside the installation frame 1 , and an output end of the telescopic cylinder 11 is fixedly connected to an anti-slip plate 12 .

[0055] Example 3

[0056] A method for using a support and reinforcement device for a roadbed culvert comprises the following steps:

[0057] 1. Initial state, transportation positioning stage;

[0058] Device form: the moving wheel 10 contacts the bottom surface of the culvert, and the anti-skid plate 12 is retracted to the high position by the telescopic cylinder 11; the driving motor 73 stops rotating, and the sliding seat 72 is located at the initial end of the reciprocating screw rod 71; the connecting rod 74 is in an inclined state, the support column 5 is retracted, and the arc-shaped top plate 6 is in the lowest position, leaving a gap with the top of the culvert.

[0059] Movement process: The installation frame 1 is manually pushed, and the device is moved to the predetermined reinforcement position in the culvert by rolling the moving wheels 10.

[0060] 2. Bottom fixing stage;

[0061] Hydraulic cylinder action: start the telescopic cylinder 11, and its output end pushes the anti-slide plate 12 to move vertically downward;

[0062] The anti-skid plate 12 presses the bottom surface of the culvert, the moving wheel 10 is lifted off the ground, and the bottom of the device is completely fixed.

[0063] The friction between the anti-skid plate 12 and the ground forms a bottom anchor point to resist the reaction force during subsequent lifting.

[0064] 3. Top support adjustment stage;

[0065] Step 1: Start the driving mechanism: The driving motor 73 rotates forward, driving the reciprocating screw 71 to rotate. The reciprocating screw 71 pushes the left and right sliding seats 72 to move toward each other along the screw axis through thread engagement, and moves toward the center of the mounting shell 3.

[0066] The second sliding groove 15 of the sliding seat 72 is in sliding engagement with the circumferential edge of the mounting shell 3;

[0067] The slider 13 slides in the first sliding groove 8 and the second sliding groove 15, limiting the sliding seat 72 to only horizontal movement without radial deviation.

[0068] Step 2: The connecting rod pushes the support column: the sliding seat 72 moves inward horizontally, driving the bottom end of the connecting rod 74 to move inward synchronously; the top end of the connecting rod 74 pushes the bottom end of the support column 5. Since the support column 5 is hinged to the support plate 4, the support column 5 rotates upward with the hinge point as the axis.

[0069] Step 3: Expand the support column: When the support column 5 rotates upward, the telescopic section inside it, such as the hydraulic or mechanical sleeve structure, is stretched synchronously under tension; the top of the support column 5 pushes the arc-shaped top plate 6 to rise vertically until the rubber pad 9 fits tightly against the curved surface of the culvert top wall.

[0070] 4. Dynamic adjustment stage;

[0071] Height fine-tuning: The driving motor 73 rotates slightly forward and reverse to drive the sliding seat 72 to move slightly, and the rotation angle of the support column 5 is accurately controlled by the connecting rod 74, thereby adjusting the lifting height of the arc-shaped top plate 6.

[0072] Bottom pressure optimization: adjust the extension of the telescopic cylinder 11 to change the pressing force of the anti-slip plate 12 on the bottom surface of the culvert to avoid overload or sliding.

[0073] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
