Description

TECHNICAL FIELD

[0001] The present application relates to the underwater screed construction technical field, and particularly relates to an underwater screed with obstacle processing function and a construction method. BACKGROUND

[0002] At present, in the underwater operation process of the underwater screed, the stone is mainly dropped through the distribution pipe. In this process, sometimes high stone blocks (for example, high stone blocks on the working surface which have been separated from the seabed in the early stage of rock drilling but still remain on the working surface) are encountered, which will interfere with the distribution pipe of the underwater screed. The current solution is to use a special rock drilling ship or a tugboat to break the high stone blocks, which is time-consuming, laborious and high in cost. SUMMARY

[0003] The present application aims to overcome the deficiency that high stone blocks are encountered during the movement of the distribution pipe and interfere with the distribution pipe in the background art, and to provide an underwater screed with obstacle processing function.

[0004] In a first aspect, the present application provides an underwater screed with obstacle processing function, comprising: a screed main frame; a stone digging device, comprising a digging arm and a bucket connected to the front end of the digging arm, the digging arm is arranged on the screed main frame, and the digging arm can move horizontally and longitudinally relative to the screed main frame.

[0005] The underwater screed with obstacle processing function provided by the present application is characterized in that a stone digging device is arranged on the screed main frame, the stone digging device comprises a digging arm, and a bucket is arranged at the front end of the digging arm. When a stone block that may interfere with the distribution pipe is encountered, the bucket is moved to a predetermined position by moving the digging arm horizontally and longitudinally relative to the screed main frame, and the stone block is dug up. Then, the stone block is moved to another position by moving the digging arm horizontally and longitudinally relative to the screed main frame, so as to achieve the purpose of assisting in obstacle removal during the underwater operation of the underwater screed.

[0006] Preferably, a horizontal and longitudinal movement mechanism is arranged on the screed main frame, the horizontal and longitudinal movement mechanism can move horizontally and longitudinally relative to the screed main frame, the stone digging device is connected to the horizontal and longitudinal movement mechanism, a distribution pipe is arranged on the horizontal and longitudinal movement mechanism, and the distribution pipe and the digging arm can move horizontally and longitudinally together with the horizontal and longitudinal movement mechanism.

[0007] The digging arm and the material pipe are integrated on the same horizontal and vertical moving mechanism, which can move horizontally and vertically relative to the main frame of the leveling machine to drive the digging arm and the material pipe to move horizontally and vertically relative to the main frame of the leveling machine, thereby reducing at least one set of horizontal and vertical moving mechanism and effectively controlling the increase of the load of the digging arm and the bucket on the main frame of the leveling machine.

[0008] Preferably, the digging arm is connected with the horizontal and vertical moving mechanism through a rotating assembly, and the digging arm can rotate relative to the horizontal and vertical moving mechanism through the rotating assembly.

[0009] By arranging the rotating assembly, the bucket can not only move horizontally and vertically, but also rotate horizontally, so that the bucket is more flexible during construction.

[0010] Preferably, the rotating assembly is arranged outside the material pipe to prevent the rotating assembly and the material pipe from interfering with each other.

[0011] Preferably, the material pipe comprises an upper pipe and a lower pipe, the upper pipe is detachably inserted into the inside of the lower pipe, and the rotating assembly is arranged outside the upper pipe.

[0012] Since the upper pipe and the lower pipe are detachably connected, the upper pipe and the lower pipe can be separated, so that the upper pipe and the lower pipe can be separated before the submersible leveling machine is launched, the whole formed by the upper pipe, the digging arm and the bucket is hoisted to the upper side of the submersible leveling machine, and then the upper pipe is inserted into the lower pipe, so that the digging arm and the bucket do not affect the stability of the submersible leveling machine during launching.

[0013] Preferably, the rotating assembly comprises a base arranged outside the upper pipe and a rotating upper support, and the base and the rotating upper support are rotatably connected through a first rotating bearing.

[0014] Preferably, the digging arm root part is a fork with two side walls, the two side walls are located on opposite sides of the material pipe away from the end of the bucket, and the side walls are connected with the rotating assembly to reduce the overturning moment of the digging device on the horizontal and vertical moving mechanism.

[0015] Preferably, a first telescopic mechanism is further arranged, the digging arm is vertically hinged with the rotating assembly, one end of the first telescopic mechanism is connected with the rotating assembly, the other end of the first telescopic mechanism is connected with the digging arm, and the first telescopic mechanism can drive the digging arm to vertically swing relative to the rotating assembly.

[0016] Preferably, a material guide hose is further arranged, and the lower end of the material guide hose extends into the material pipe through the top of the material pipe.

[0017] Preferably, the bucket can knock the material guide hose.

[0018] The underwater screed machine with the obstacle processing function has the advantages that after the stones enter the feeding bin, the stones are conveyed by the feeding conveying device to the position corresponding to the feeding port of the material guide hose and enter the feeding port of the material guide hose, and then the stones enter the material distribution pipe through the material guide hose for distribution. In the above process, since the lower end of the material guide hose extends into the material distribution pipe from the top of the material distribution pipe, the stones can be accurately conveyed into the material distribution pipe for distribution through the material guide hose based on the deformation of the material guide hose even if there is a certain deviation in the vertical direction between the discharging position of the feeding conveying device and the feeding position of the top of the material distribution pipe. This greatly reduces the difficulty of the operator in operating the feeding conveying device to vertically align the material distribution pipe, thereby effectively reducing the skill requirement for the operator and reducing the labor cost.

[0019] However, in the above process, the material guide hose is prone to deformation, so when the material guide hose is stuck with the stones, the position where the material guide hose is stuck with the stones can be knocked by the excavator bucket, so that the material guide hose can be kept unobstructed.

[0020] Preferably, the excavator bucket can knock the material distribution pipe.

[0021] Preferably, the excavator bucket can knock the material guide hose and the material distribution pipe.

[0022] Preferably, the screed machine main frame comprises two second cross beams arranged at intervals.

[0023] The transverse and longitudinal movement mechanism comprises a transverse movement mechanism and a longitudinal movement mechanism arranged on the transverse movement mechanism. The transverse movement mechanism is arranged between adjacent second cross beams and can move transversely relative to the second cross beams. The longitudinal movement mechanism is used to drive the excavator arm to move longitudinally.

[0024] In a second aspect, the application further provides a construction method based on the underwater screed machine with the obstacle processing function. The construction method comprises the following steps: S1. The excavator bucket excavates the obstacle, and the excavator bucket rotates vertically upward relative to the excavator arm; S2. The excavator arm drives the excavator bucket and the obstacle to move relative to the screed machine main frame until the excavator bucket can extend outside the screed machine main frame; S3. The excavator arm is rotated to drive the excavator bucket and the obstacle to rotate and extend outside the screed machine main frame; S4. The excavator bucket rotates vertically downward relative to the excavator arm to dump the obstacle in the excavator bucket outside the screed machine main frame.

[0025] The construction method described in this application is based on an underwater screed machine with obstacle removal function. During the operation of the underwater screed machine, when encountering rocks that may interfere with the material placement pipe, the excavator arm moves horizontally and vertically relative to the main frame of the screed machine to move the bucket to a predetermined position and dig up the rocks. Then, the excavator arm moves horizontally and vertically relative to the main frame of the screed machine to move the rocks to a position outside the main frame of the screed machine, so as to achieve the purpose of assisting in obstacle removal during underwater operations of the underwater screed machine.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: The underwater screed machine described in this application, which also has obstacle removal capabilities, has a rock-digging device installed on its main frame. The rock-digging device includes a digging arm and a bucket at the front end of the digging arm. When encountering rocks that may interfere with the material delivery pipe, the digging arm moves horizontally and vertically relative to the main frame of the screed machine to move the bucket to a predetermined position and dig up the rocks. Then, the digging arm moves horizontally and vertically relative to the main frame of the screed machine to move the rocks to other positions, thereby achieving the purpose of assisting in obstacle removal during underwater operations.

When encountering rocks that may interfere with the material placing pipe 7, the digging arm 101 moves horizontally and vertically relative to the main frame 100 of the screed machine to move the digging bucket 102 to a predetermined position and dig up the rocks. Then, the digging arm 101 moves horizontally and vertically relative to the main frame 100 of the screed machine to move the rocks to other positions, so as to achieve the purpose of assisting in obstacle removal during underwater operations of the underwater screed machine.

[0043] In a preferred embodiment, a material distribution pipe 7 is provided on the main frame 100 of the leveling machine, and the top and bottom of the material distribution pipe 7 are both open.

10. A construction method, characterized in that, The underwater leveling machine with obstacle removal function as described in any one of claims 1-9 includes the following steps: S1. The bucket (102) digs up the obstacle, and the bucket (102) rotates vertically upward relative to the arm (101); S2. The excavator arm (101) drives the bucket (102) and the obstacle to move relative to the main frame (100) of the leveler until the bucket (102) can extend out of the outside of the main frame (100) of the leveler; S3. Rotate the arm (101) to drive the bucket (102) and the obstacle to rotate and extend outward from the main frame (100) of the leveler; S4. The bucket (102) rotates vertically downward relative to the arm (101) to dump the obstacles in the bucket (102) onto the outside of the leveler frame (100).
