Description

Technical Field

[0001] The utility model relates to the technical field of underwater base bed filling equipment, in particular to a conduit riprap machine. Background Art

[0002] Underwater gravel bed laying and leveling is a crucial process in the construction of gravity-based hydraulic structures, bridge foundations, and tunnel sinking tubes. During underwater gravel bed laying and leveling operations, direct stone dumping makes it difficult to control the location of the stone in the water, resulting in uneven thickness in the dumped area. Therefore, a stone dumping device is required to adjust the dumping position. For example, document CN210238519U discloses an underwater stone dumping and leveling device. This device can adjust the height of a guide tube so that the bottom of the tube approaches the desired filling location on the seabed. This reduces the distance the gravel travels from the bottom of the tube to the seabed, preventing the gravel from being disturbed by the current and allowing it to fall directly to the desired filling location. However, the stone dumping device can only move along the length of the ship. If the next dumping point is not aligned with the current dumping point, the ship must be moved multiple times to adjust the position of the guide tube, which is inconvenient. Utility Model Content

[0025] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0026] like Figure 1-5 As shown, an embodiment of the present invention provides a conduit riprap machine, which is mounted on a running track 6. The running track 6 is arranged on the hull and parallel to the length of the hull. The conduit riprap machine includes a guide pipe 1, a chassis 4, a mounting base 2, and a control cabinet storing a control program. The guide pipe 1 is assembled from multiple pipe sections, and adjacent pipe sections are connected and fixed by bolts. The guide pipe 1 is longitudinally arranged on the mounting base 2, and the mounting base 2 is provided with a winch 3 for driving the guide pipe 1 to move longitudinally.

[0027] An ultrasonic sensor 9 is provided on the bottom pipe section of the material guide pipe 1;

[0028] A traveling mechanism 5 that can move along a traveling track 6 is provided at the bottom of the chassis 4 (the traveling mechanism 5 is driven by a motor reducer to rotate a sprocket, and the motor reducer is electrically connected to the control cabinet. The traveling mechanism 5 has various embodiments in the prior art, and the specific structure of the traveling mechanism 5 is not described in detail here);

[0029] The chassis 4 is provided with a hydraulic telescopic device 7 for driving the mounting base 2 to move laterally. The ultrasonic sensor 9, the hoist 3, the traveling mechanism 5 and the hydraulic telescopic device 7 are all electrically connected to the control cabinet.

[0030] The ultrasonic sensor 9 transmits its distance from the seabed to the control cabinet, so that the control cabinet can measure the vertical distance between the seabed and the bottom end of the guide pipe 1 and the flatness information of the seabed in the area near the guide pipe 1 in real time during the movement of the guide pipe 1 (there are many embodiments of using ultrasonic sensors 9 to measure distance and flatness in the prior art. The specific measurement method is not the technical problem to be solved by this application and will not be described here).

[0031] Specifically, the control cabinet controls the winch 3 to insert the guide pipe 1 into the seawater and keep a certain distance from the seabed base bed, the ultrasonic sensor 9 detects the flatness information of the seabed base bed, the control cabinet controls the walking mechanism 5 to move the guide stone riprap along the walking track 6, and controls the hydraulic telescopic device 7 to move the mounting base 2 laterally, and moves the guide pipe 1 to above the position where the seabed base bed needs to be filled, and the control cabinet controls the winch 3 to move the guide pipe 1 downward, so that the bottom end of the guide pipe 1 is close to the position where the seabed base bed needs to be filled, reducing the distance of the gravel falling from the bottom end of the guide pipe 1 to the seabed base bed, thereby preventing the gravel from being disturbed by the ocean current and deviating from the position to be filled; in addition, it is easy to imagine that the control cabinet can also use the bottom end of the guide pipe 1 to perform scraping construction on the seabed base bed by controlling the movement of the guide pipe 1; in a further improved embodiment, a scraper is also installed at the end of the guide pipe 1 to improve the effect of the scraping construction.

[0032] In order to optimize the assembly process of the guide pipe 1, there are at least two length specifications of the pipe segments, so that the guide pipe stone throwing machine can adjust the number of pipe segments of different lengths according to the specific construction conditions and construction environment; obviously, using more longer pipe segments can simplify the assembly process of the guide pipe 1, and using more shorter pipe segments can reduce the difficulty of transporting the pipe segments.

[0033] To improve the driving effect of the winch 3 on the guide pipe 1, the outer wall of the guide pipe 1 is provided with a lifting lug 8. The winch 3 is connected to the lifting lug 8 via a lifting rope, thereby driving the guide pipe 1 to move longitudinally. To enhance the stability of the guide pipe 1 during longitudinal movement, there are two lifting lugs 8, which are symmetrically arranged along the outer axis of the guide pipe 1. The number of winches 3 and the number of lifting lugs 8 are the same. When the guide pipe 1 is used to level the seabed, the pipe body between the position of the lifting lug 8 and the bottom end of the guide pipe 1 will be subjected to shear force, which may damage the connection between the pipe sections and cause the guide pipe 1 to bend. As a preferred embodiment of the present invention, the lifting lug 8 is provided on the bottommost pipe section of the guide pipe 1.

[0034] The mounting seat 2 is fixedly connected to a slide rail 21, which is slidably mounted inside the chassis 4. The movable end of the hydraulic telescopic device 7 is fixedly connected to the slide rail 21, so that the hydraulic telescopic device 7 pushes the mounting seat 2 and the guide tube 1 to move laterally through the slide rail 21 (the movement method of the hydraulic telescopic device 7 to push the object to move laterally has multiple embodiments in the prior art, and the specific structure of the hydraulic telescopic device 7 is not described here). However, relying solely on the hydraulic telescopic device 7 to fix the lateral position of the guide tube 1 is not reliable enough and will also affect the service life of the slide rail 21. In a preferred embodiment of the present utility model, a plurality of pin holes 22 are equidistantly opened on the slide rail 21 (in a more specific embodiment, the distance between each adjacent two pin holes 22 is 0.8m), and a claw 41 is provided on the chassis 4, which is embedded in the pin hole 22 by the claw 41, so that the relative position of the slide rail 21 and the chassis 4 is fixed (the fixing method of the claw 41 and the pin hole 22 has multiple embodiments in the prior art, and the specific structure of the claw 41 and the pin hole 22 is not described here).

[0035] During the stone throwing process, the gravel falls into the guide pipe 1 from the top of the guide pipe 1 through external mechanical equipment such as excavators and loaders. In order to make the gravel better enter the guide pipe 1, as a preferred embodiment of the present invention, a conduit hopper 10 is provided at the top of the guide pipe 1 to provide guidance for the gravel to fall into the guide pipe 1.

[0036] In summary, the guide tube riprap machine, through the provided walking mechanism 5, walking track 6 and hydraulic telescopic device 7, enables the guide tube 1 to move in all directions in a horizontal position, thereby bringing convenience to the staff.

[0037] The above-described embodiments merely represent implementation methods of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
