Description

Technical Field

[0001] The utility model relates to the technical field of dredging, and in particular to a mobile disturbance dredging platform stabilizing device. Background Art

[0002] After a long period of time, the siltation in harbors, docks and riverbeds will gradually become serious, especially in areas where ships are sailing, which will seriously affect the navigation safety of ships. Therefore, it is necessary to dredge the harbors or docks with serious siltation. Mobile dredging platforms are one of the equipment used for dredging.

[0003] The existing mobile dredging platforms generally use the hull to drive the suction head to mechanically disturb the silt below the harbor or dock, or use high-pressure gas to impact the silt, so that the silt is re-suspended through mechanical or pneumatic disturbance and floats to the water surface and then flows away with the water flow to achieve dredging. However, in dredging by this method, the suction head is only rotated by the traction of a traction rope to adjust the height, so that the suction head has space for free movement in the vertical direction. As a result, during the dredging process, if a higher silt pile or a larger water flow impact is encountered, the suction head will shake up and down to a large extent, thereby affecting the dredging effect.

DETAILED DESCRIPTION

[0022] 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.

[0023] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0024] like Figures 1 to 4 As shown, the utility model provides a mobile disturbance dredging platform stabilizing device, including a hull 1, a traction device 2 and a mounting groove 3 are arranged at the tail of the hull 1, a connecting rod 4 is rotatably connected to the inner wall of the mounting groove 3, a disturbance rake head 5 is arranged at the end of the connecting rod 4, and the traction device 2 is used to pull the connecting rod 4 to rotate around the connection between the connecting rod 4 and the hull 1, and limited limit devices 6 for abutting against the upper surface of the connecting rod 4 are commonly arranged on the two opposite inner side walls of the mounting groove 3, and the limited limit device 6 is used to limit the activity space of the disturbance rake head 5 when working.

[0025] When the utility model is used, the hull 1 moves on the water surface, and the connecting rod 4 is pulled by the traction device 2 to rotate around the connection with the hull 1, so as to adjust the height of the disturbance rake head 5 to adapt to different siltation conditions on the bottom of the harbor or dock and other areas, so that the disturbance rake head 5 can effectively contact the silted mud and mechanically disturb the mud or pneumatically disturb the mud, that is, spray high-pressure gas, or a combination of both, so that the silt is suspended again and floats to the water surface, so that the mud follows the water flow and completes the dredging of the harbor or dock and other areas, wherein the disturbance rake head 5 is a prior art, which generally involves the rotation of a spiral plate to disturb the mud and the spraying of air through an air pipe to impact the mud, etc., and can refer to the corresponding structure on the existing drag-suction ship, and the specific technical principle will not be elaborated in detail here.

[0026] After the position of the disturbance rake head 5 is adjusted, the limited limit device 6 is abutted against the top of the connecting rod 4, so that the movement space of the connecting rod 4 in the vertical direction is limited under the traction force of the traction device 2 and the pressure of the limited limit device 6, thereby limiting the activity space of the disturbance rake head 5 during work, ensuring the stability of the disturbance rake head 5 during work, and avoiding the problem that the disturbance rake head 5 shakes greatly when it is impacted by water flow or contacts with silt piles, thereby affecting the dredging effect.

[0027] The limited limit device 6 includes two slides 601 which are respectively slidably arranged on two opposite side walls in the installation groove 3, each slide 601 is provided with a fixing device 602, each fixing device 602 is provided with a pressure plate 603 which is slidably connected to the slide 601, and each pressure plate 603 is located above the connecting rod 4 and can move freely in the fixing device 602 in the vertical direction, and a lifting device 611 connected to the slide 601 is provided on the hull 1, and the lifting device 611 is used to control the movement of the slide 601 in the vertical direction.

[0028] When the limited limit device 6 is in use, the fixing device 602 is used to push the pressure plate 603 to abut against the top of the connecting rod 4, so that the connecting rod 4 is fixed under the action of the upward traction force of the traction device 2 and the downward pressure of the pressure plate 603, thereby limiting the vertical movement space of the connecting rod 4, and then limiting the vertical movement space of the disturbance rake head 5 when working.

[0029] When the connecting rod 4 is pulled by the traction device 2 to adjust the height of the disturbance rake head 5, the fixing device 602 moves upward to away from the pressure plate 603, so that the pressure plate 603 slides on the slide plate 601 through the top pressure of the connecting rod 4 when the connecting rod 4 moves. When the position adjustment of the disturbance rake head 5 is completed, the fixing device 602 pushes the pressure plate 603 to abut against the top of the connecting rod 4 to limit the activity space of the disturbance rake head 5, thereby ensuring the stability of the disturbance rake head 5 during operation and avoiding large shaking of the disturbance rake head 5 when it is impacted by water flow or contacts with silt pile.

[0030] The fixing device 602 includes a threaded rod 604 and a sliding rod 605 which are arranged parallel to the vertical direction on the slide plate 601. The threaded rod 604 is threadedly connected with a locking plate 606 which is slidably sleeved with the sliding rod 605, and the locking plate 606 is located above the pressure plate 603, which is sleeved on the threaded rod 604 and the sliding rod 605.

[0031] The fixing device 602 drives the threaded rod 604 to rotate through a driving device such as a motor, thereby driving the locking plate 606 to slide up and down along the threaded rod 604 and the sliding rod 605 to move away from the pressing plate 603 or push the pressing plate 603 to press down the connecting rod 4.

[0032] The bottom of the locking plate 606 is connected to a buffer plate 608 via a spring 607 . A plurality of limiting posts 609 are vertically arranged on the buffer plate 608 , and the limiting posts 609 vertically penetrate the locking plate 606 upward to the other side.

[0033] When the buffer plate 608 is against the pressure plate 603, the pressure plate 603 is against the top of the connecting rod 4 through the elastic force of the spring 607 and the spiral drive of the threaded rod 604 during rotation. At this time, the spring 607 is gradually compressed so that the pressure plate 603 has a certain buffer space, avoiding damage to the locking plate 606 caused by excessive contact pressure, and making the connecting rod 4 have a smaller activity space in the vertical direction. The movement of the connecting rod 4 is buffered by the spring 607, reducing the damage caused by the impact of the connecting rod 4 and the disturbance rake head 5 on the locking plate 606 when they shake, which not only extends the service life, but also avoids the problem of excessive shaking of the disturbance rake head 5 affecting the dredging effect.

[0034] A plurality of pressing rollers 610 are rotatably connected to the bottom of the pressing plate 603 at equal intervals.

[0035] By abutting the top of the connecting rod 4 with the pressure roller 610, the sliding friction between the connecting rod 4 and the pressure plate 603 is converted into rolling friction between the pressure roller 610 and the connecting rod 4, thereby reducing the friction resistance, facilitating the connecting rod 4 to press the pressure plate 603 and allowing the pressure plate 603 to move along the connecting rod 4, and also reducing the wear on the connecting rod 4 and the pressure plate 603.

[0036] The traction device 2 includes a traction roller 201 and a bracket 202 arranged on the hull 1 . The traction roller 201 is connected to a traction rope 203 . The bracket 202 is provided with a guide roller 204 . The traction rope 203 is connected to the connecting rod 4 via the guide roller 204 .

[0037] The traction roller 201 is driven to rotate by a driving device such as a motor, so that the traction rope 203 is wound or released, so that the connecting rod 4 is rotated upward or downward under the traction of the traction rope 203 and the action of its own gravity and the gravity of the disturbance rake head 5, thereby realizing the adjustment of the height of the disturbance rake head 5.

Any technical personnel in this field may make slight changes or modifications to other equivalent embodiments without departing from the scope of the technical means disclosed in the content of the utility model, but they should still be regarded as technologies or embodiments that are essentially the same as the utility model.
