Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering technology, and in particular to a rapid prototyping equipment for hydraulic tunnel lining. Background Technology

[0002] As water conservancy projects develop towards deeper, longer distances, and more complex geological conditions (such as inter-basin water transfer projects and underground power plant tunnels), higher demands are placed on the efficiency, quality, and safety of lining construction. Traditional construction methods can no longer meet the engineering requirements of "short construction period, high quality, and low risk." Therefore, it is necessary to develop rapid prototyping equipment that integrates "rapid formwork, continuous pouring, intelligent control, and adaptability to complex working conditions" to break through traditional technical bottlenecks and promote the mechanization and automation upgrade of water conservancy tunnel lining construction.

[0003] Traditional support devices used for lining hydraulic tunnels in the present technology often require manual or individual control of multiple support units, which can easily lead to uneven stress on the top support plate, causing the support to loosen and resulting in over-pouring or leakage of concrete, which in turn causes the formwork to tilt, creating serious quality and safety hazards. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rapid prototyping equipment for hydraulic tunnel lining.

[0005] This utility model is achieved by the following technical solution: a rapid prototyping device for hydraulic tunnel lining, including a support rod, a support component is provided inside the support rod, and an auxiliary component is provided at the bottom of the support component.

[0006] The support assembly includes a drive motor, a motor rotating rod fixedly connected to the output end of the drive motor, a rotating rod fixedly connected to the end of the motor rotating rod away from the drive motor, a drive gear fixedly connected to the outer wall of the rotating rod, a driven gear meshing with the outer wall of the drive gear, a support rod fixedly connected to the inner wall of the driven gear, a top support plate fixedly connected to the outer wall of the support rod, a reverse gear meshing with the outer wall of the drive gear, a rotating rod fixedly connected to the inner wall of the reverse gear, a driven gear meshing with the outer wall of the reverse gear, a support rod fixedly connected to the inner wall of the driven gear, and a top support plate fixedly connected to the outer wall of the support rod.

[0007] As a further improvement to the above solution, the outer wall of the drive motor is fixedly connected to the inner wall of the support rod, the outer wall of the motor rotating rod is rotatably connected to the inner wall of the support rod, the outer wall of the rotating rod is rotatably connected to the inner wall of the support rod, the outer wall of the support rod is rotatably connected to the inner wall of the support rod, and the support rod extends through the inner wall of the support rod.

[0008] As a further improvement to the above solution, the outer wall of the second rotating rod is rotatably connected to the inner wall of the support rod, the outer wall of the second support rod is rotatably connected to the inner wall of the support rod, and the second support rod penetrates through the inner wall of the support rod and extends thereafter.

[0009] With the above technical solution, after the drive motor starts, its output end drives the motor rotating rod to rotate. The motor rotating rod drives the rotating rod to rotate synchronously on the inner wall of the support rod, and the drive gear on the outer wall of the rotating rod rotates together with it. The drive gear meshes with the driven gear, driving the driven gear and the support rod fixed on the inner wall to rotate.

[0010] As a further improvement to the above solution, the auxiliary component includes a bottom support plate, the top of which is fixedly connected to a support housing, and the inner wall of the support housing is provided with a limiting groove.

[0011] As a further improvement to the above solution, a limiting slider is slidably connected to the inner wall of the limiting groove, the top of the limiting slider is fixedly connected to the bottom of the support rod, a lifting threaded rod is threadedly connected to the inner wall of the limiting slider, and the outer wall of the lifting threaded rod is rotatably connected to the inner wall of the support shell.

[0012] As a further improvement to the above solution, a worm gear is fixedly connected to the outer wall of the lifting threaded rod, a worm is meshed with the outer wall of the worm gear, and the outer wall of the worm is rotatably connected to the inner wall of the supporting shell.

[0013] As a further improvement to the above solution, the front of the worm gear penetrates through the inner wall of the support housing and extends therein. A second drive motor is fixedly connected to the front of the worm gear. The bottom of the second drive motor is fixedly connected to the top of the bottom support plate. A self-locking universal wheel is fixedly connected to the bottom of the bottom support plate.

[0014] Through the above technical solution, the bottom support plate provides basic support for the overall structure, and the top support shell forms the installation space. When the second drive motor starts, its output end drives the worm gear to rotate on the inner wall of the support shell. The worm gear meshes with the worm wheel, thereby driving the worm wheel and the lifting threaded rod fixed on the inner wall to rotate synchronously.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a drive motor. Upon startup, the output of the drive motor drives a rotating rod to rotate. This rotating rod then rotates synchronously within the inner wall of the support rod, while a drive gear on the outer wall of the rotating rod rotates along with it. The drive gear meshes with a driven gear, causing the driven gear and the support rod fixed to the inner wall to rotate. The support rod then moves synchronously with the top support plate fixed to the outer wall. Simultaneously, the drive gear meshes with a reverse gear, causing the reverse gear and a rotating rod fixed to the inner wall to rotate within the support rod. The reverse gear then meshes with the driven gear, driving the driven gear and the support rod fixed to the inner wall to rotate. The support rod then moves the top support plate fixed to the outer wall. Thus, through the meshing and transmission of the drive gear with the driven gear and the reverse gear, the top support plates 1 and 2 coordinate their movements to complete the support function. This solves the problems of poor synchronization, low efficiency, and weak adaptability in traditional support devices, and is particularly suitable for rapid lining construction of large-section and variable-section hydraulic tunnels, significantly improving support stability and construction efficiency.

[0017] This utility model provides basic support for the overall structure through a bottom support plate, while the top support shell forms the installation space. When the second drive motor starts, its output end drives the worm gear to rotate on the inner wall of the support shell. The worm gear meshes with the worm wheel, thereby driving the worm wheel and the lifting threaded rod fixed on the inner wall to rotate synchronously. When the lifting threaded rod rotates, it drives the limiting slider, which is threaded to the inner wall, to slide along the inner wall of the limiting groove. The top of the limiting slider is fixedly connected to the bottom of the support rod, thereby driving the support rod and the support assembly above to achieve lifting and lowering movement. The self-locking universal wheels at the bottom of the bottom support plate can realize the movement and fixation of the entire equipment. By controlling the forward and reverse rotation of the second drive motor, the support height can be adjusted. Together with the support assembly, it can achieve precise support for the tunnel lining template. Moreover, the worm gear transmission has a natural reverse self-locking characteristic. This auxiliary component, through its precise transmission, self-locking safety, and convenient movement design, solves the pain points of traditional height adjustment devices such as low accuracy, easy settlement, and difficulty in relocation. Together with the support assembly, it forms a composite function of adjustable height and variable support range, significantly improving the efficiency and safety of hydraulic tunnel lining construction.

[0029] The outer wall of the drive motor 201 is fixedly connected to the inner wall of the support rod 1, the outer wall of the motor rotating rod 202 is rotatably connected to the inner wall of the support rod 1, the outer wall of the rotating rod 203 is rotatably connected to the inner wall of the support rod 1, the outer wall of the support rod 206 is rotatably connected to the inner wall of the support rod 1, and the support rod 206 penetrates through the inner wall of the support rod 1 and extends thereafter.

[0030] The outer wall of the rotating rod 209 is rotatably connected to the inner wall of the support rod 1, and the outer wall of the support rod 211 is rotatably connected to the inner wall of the support rod 1. The support rod 211 passes through the inner wall of the support rod 1 and extends thereafter.

[0031] Auxiliary component 3 includes a bottom support plate 301, and a support housing 302 is fixedly connected to the top of the bottom support plate 301. A limiting groove 303 is formed on the inner wall of the support housing 302.

[0032] The inner wall of the limiting slide groove 303 is slidably connected to the limiting slider 304. The top of the limiting slider 304 is fixedly connected to the bottom of the support rod 1. The inner wall of the limiting slider 304 is threadedly connected to the lifting threaded rod 305. The outer wall of the lifting threaded rod 305 is rotatably connected to the inner wall of the support shell 302.

[0033] A worm gear 306 is fixedly connected to the outer wall of the lifting threaded rod 305. A worm 307 is meshed with the outer wall of the worm gear 306. The outer wall of the worm 307 is rotatably connected to the inner wall of the support housing 302.

The bottom of the second drive motor 308 is fixedly connected to the top of the bottom support plate 301. A self-locking caster wheel 309 is fixedly connected to the bottom of the bottom support plate 301.

[0035] The implementation principle of the rapid prototyping equipment for hydraulic tunnel lining in this embodiment is as follows: When the drive motor 201 starts, its output end drives the motor rotating rod 202 to rotate. The motor rotating rod 202 drives the rotating rod 203 to rotate synchronously on the inner wall of the support rod 1. The drive gear 204 on the outer wall of the rotating rod 203 rotates together with it. The drive gear 204 meshes with the driven gear 205, driving the driven gear 205 and the support rod 206 fixed on the inner wall to rotate. The support rod 206 also drives the top support plate 207 fixed on the outer wall to move synchronously. At the same time, the drive gear 204 meshes with the reverse gear 208, driving the reverse gear 208 and the rotating rod 209 fixed on the inner wall to rotate on the inner wall of the support rod 1. The reverse gear 208 then meshes with the driven gear 210, driving the driven gear 210 and the support rod 211 fixed on the inner wall to rotate. The support rod 211 drives the top support plate 212 fixed on the outer wall to move. Thus, through the meshing transmission of the drive gear 204 with the driven gear 205 and the reverse gear 208 respectively, the top support plate 207 and the top support plate 212 achieve coordinated action to complete the support function. This solves the problems of poor synchronization, low efficiency, and weak adaptability of traditional support devices, and is especially suitable for rapid lining construction of large-section and variable-section hydraulic tunnels, significantly improving support stability and construction efficiency. Furthermore, the bottom support plate 301 provides basic support for the overall structure, and its top support shell 302 forms the installation space. When the drive motor 308 starts, its output end drives the worm gear 307 to rotate on the inner wall of the support shell 302. The worm gear 307 meshes with the worm wheel 306, thereby driving the worm wheel 306 and the lifting threaded rod 305 fixed on the inner wall to rotate synchronously. When the lifting threaded rod 305 rotates, it drives the limiting slider 304, which is threaded to the inner wall, to slide along the inner wall of the limiting groove 303. The top of the limiting slider 304 is fixedly connected to the bottom of the support rod 1, thereby driving the support rod 1 and the support assembly 2 above it to achieve lifting and lowering movements. The self-locking universal wheel 309 at the bottom of the bottom support plate 301 can realize the movement and fixation of the entire equipment. By controlling the forward and reverse rotation of the drive motor 308, the support height can be adjusted. Together with the support assembly 2, it can achieve precise support for the tunnel lining template. Moreover, the worm gear transmission has a natural reverse self-locking characteristic. This auxiliary component, through its design of precision transmission, self-locking safety, and convenient movement, solves the pain points of traditional height adjustment devices such as low accuracy, easy settlement, and difficulty in relocation. Together with the support assembly, it forms a composite function of adjustable height and variable support range, significantly improving the efficiency and safety of hydraulic tunnel lining construction.
