Description

Technical Field

[0001] The utility model relates to the technical field of underwater riprap, in particular to an underwater riprap positioning device. Background Art

[0002] In underwater construction or geological exploration, it is often necessary to locate underwater rocks for subsequent operations. However, due to the complexity of the underwater environment, traditional positioning devices are often unable to accurately locate the position of the rocks, thus affecting the effect of construction or exploration.

[0003] The patent with the announcement number CN215518782U discloses a high-precision underwater riprap device, including a hull, a fixed seat fixedly connected to one side of the hull, a hydraulic cylinder fixedly connected to one side of the fixed seat, a fixed frame fixedly connected to one end of the hydraulic rod of the hydraulic cylinder, a motor fixedly connected to one side of the fixed frame, a worm fixedly connected to one end of the motor output shaft, a threaded rod movably connected to one side of the fixed frame, one end of the threaded rod passes through the fixed frame and is fixedly connected to a worm gear, and the worm gear is engaged with the worm gear, a sliding rod movably connected to one side of the threaded rod, and a limited position slot is provided on one side of the fixed frame. The patent can enable the device to accurately position the riprap through the feeding pipe, thereby improving the riprap effect of the device, and can also facilitate the staff to adjust the position of the riprap through the sliding rod, thereby improving the flexibility of the device. However, the patent still has the following defects: ① The rotation angle of the feed pipe is limited. When the hull is long, since the feed pipe cannot move, it is still necessary to move the hull to carry out underwater stone throwing operations at different positions, and it is impossible to achieve stone throwing work in a larger range; ② After the feed pipe rotates to a certain angle, an excavator is required to load the stones into the feed pipe along an inclined angle, which increases the difficulty of construction operations; ③ The lower end of the feed pipe is lower than the bottom of the ship, and the rotation angle of the feed pipe is limited, so it cannot be placed horizontally. When the ship is sailing near the coast, it is possible to run aground on a reef and there is a risk of being unable to continue moving.

[0004] In view of this, how to change the shortcomings of the above situation has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Reference Figure 1-4 The utility model provides an underwater riprap positioning device, which is installed on a hull 17 and is used for positioning riprap operations. The specific structure includes a connecting frame 1, a slide rail 2, a sliding seat 3 and a feeding pipe 4. Among them, the connecting frame 1 is fixedly connected to the hull 17, the slide rail 2 is arranged along the circumference of the hull 17, the slide rail 2 is fixedly connected to the lower surface of the connecting frame 1, the sliding seat 3 is slidably connected to the slide rail 2, and the sliding seat 3 can slide relatively along the extension direction of the slide rail 2. The upper end of the feeding pipe 4 is connected to the sliding seat 3, and the feeding pipe 4 can guide the stone so that the stone can accurately fall to a suitable position, thereby accurately positioning the stone, avoiding the error between the landing point of the stone and the calculation caused by the swing of the water flow when the stone falls, causing difficulties for subsequent construction, and improving the riprap effect of the device.

[0030] In use, the blanking pipe 4 is in a vertical state, and the sliding seat 3 and the blanking pipe 4 can move along the direction of the slide rail 2. On the one hand, it is convenient to guide the stones to different positions without the need for the hull 17 to move during this process; on the other hand, the blanking pipe 4 can be moved to a handling position close to the stones, thereby reducing the displacement of stone handling and improving work efficiency.

[0031] Preferably, the utility model further includes a sleeve 5 and a connecting rod 7. The sleeve 5 is arranged parallel to the slide rail 2, and the sleeve 5 is fixedly connected to the sliding seat 3. A chute 6 is arranged along the length direction of the sleeve 5; one end of the blanking pipe 4 close to the chute 6 is hinged to the sliding seat 3; a connecting rod 7 is hinged to the lower part of one end of the blanking pipe 4, and a sliding rod 8 is vertically and fixedly connected to the end of the connecting rod 7 far from the blanking pipe 4. The sliding rod 8 is slidably connected to the chute 6 in a brakeable manner. During the sliding process of the sliding rod 8 on the chute 6, the blanking pipe 4 can be switched between a horizontal state and a vertical state. When the blanking pipe 4 is in a horizontal state, the whole blanking pipe 4 is located above the bottom of the ship at this time, and when the ship is running, there will be no phenomenon that the ship cannot pass due to hitting a reef caused by the blanking pipe 4; when the blanking pipe 4 is in a vertical state, the guiding of the stones can be realized, and underwater stone throwing operation can be carried out at this time.

[0032] Specifically, the cross-section of the sleeve 5 in the vertical direction of the utility model is in a "冂" shape, the middle part of a stop rod 9 is hinged to the side wall of the sleeve 5. When the sliding rod 8 slides to the end of the chute 6 close to the blanking pipe 4, the blanking pipe 4 is in a vertical state, and one end of the stop rod 9 flips downward under the action of its own gravity, and at the same time, the other end of the stop rod 9 flips upward to realize the blocking of the sliding rod 8.

[0033] Optionally, a collecting groove 10 is arranged at the upper end of the blanking pipe 4. The collecting groove 10 is in an inverted trapezoid shape. The upper end of the collecting groove 10 is hinged to the sliding seat 3, and a connecting ear 11 is fixedly connected to the lower end of the collecting groove 10. The connecting ear 11 is hinged to one end of the connecting rod 7.

[0034] In order to realize the horizontal placement of the blanking pipe 4, a connecting ring 12 is fixedly connected to the lower end of the blanking pipe 4. One end of a connecting rope 13 is connected to one end of the slide rail 2, and the other end of the connecting rope 13 is connected to a buckle 14. The buckle 14 is detachably connected to the connecting ring 12. Since the upper end of the collecting groove 10 is hinged to the sliding seat 3, the blocking of the sliding rod 8 by the stop rod 9 is released, so that the sliding rod 8 slides on the chute 6. By means of tools such as an excavator on the hull 17, the lower end of the blanking pipe 4 is driven to flip upward, and the connection between the buckle 14 and the connecting ring 12 is stopped. At this time, the blanking pipe 4 can be in a horizontal state.

[0035] Specifically refer to Figure 3-4 As shown, two slide rails 2 of the utility model are provided, and the two slide rails 2 are arranged in parallel. The sliding seat 3 is slidably connected to the two slide rails 2.

[0036] The slide rail 2 is an I-beam, and two sets of single-sided wheels 15 are rotatably connected to the slide seat 3. The two sets of single-sided wheels 15 are rotatably connected to the sides of the two slide rails 2 that are away from each other, and the wheel edges of the single-sided wheels 15 abut against the I-beam. A reduction motor 16 is installed on the slide seat 3, and the reduction motor 16 is transmission-connected to at least one of the single-sided wheels 15. The reduction motor 16 is connected to a power source through a controller, and can be controlled by the controller to realize forward and reverse rotation, thereby driving the slide seat 3 to slide bidirectionally along the slide rail 2. This belongs to the prior art and will not be repeated here.

[0037] Preferably, the connecting frame 1 is a triangular connecting frame, the horizontal rod of the triangular connecting frame is fixedly connected to the upper surfaces of the two slide rails 2, the vertical rod of the triangular connecting frame is used to be fixedly connected to the hull 17, and several connecting frames 1 are arranged at intervals along the length direction of the slide rails 2.
