Description

Technical Field

[0001] The invention relates to the technical field of compaction equipment, and in particular to an underwater block stone bed automatic control compaction system with a hydraulic drive mechanism. Background Art

[0002] In wharf construction, gravity wharfs have the dual functions of wharf structure and retaining structure, and are widely used with a long history of use. Underwater block stone bed tamping is an important process in gravity wharf construction. The quality of block stone bed tamping is related to the settlement of the wharf foundation during construction and after construction, and is the focus of quality control of gravity wharf. The construction specification requires that the riprap bed be tamped by half tamping in the longitudinal and transverse directions, with one hammer at each point, and divided into one initial tamping and one repeated tamping, or multiple tamping times. The number of tamping times is determined by trial tamping.

[0003] The existing underwater riprap bed compaction method often uses a grab dredger, replacing the grab with a rammer for compaction, or uses a flat barge as a work boat, and installs a crawler crane (or a strong rammer) on the deck of the barge. The rammer is lifted to a certain height (about 2-4m) by a single rope and then quickly dropped, so that the rammer is quickly rammed to the bed like a free fall. Both of these compaction methods achieve longitudinal and transverse adjacent half-ramming through the rotation angle of the boom and the amplitude of the boom, and the ramming points are arranged in an arc.

[0004] The above compaction methods all have disadvantages: the construction cost of grab dredger is high, crawler crane and dynamic compaction machine are expensive, and it is not conducive to the positioning of compaction points.

[0034] Embodiment 1

[0035] like Figure 1-2 As shown, the present invention discloses an underwater block stone bed automatic control tamping system with a hydraulic drive mechanism, specifically comprising a barge 9, a rammer 1 and a rammer lifting mechanism 10 for lifting or lowering the rammer 1, the rammer lifting mechanism 10 comprising a machine base 6, characterized in that two mutually parallel and spaced guide rails 11 are fixed on the barge 9, the machine base 6 is slidably connected to the two guide rails 11, and the tamping system further comprises a hydraulic drive mechanism 13 for driving the machine base 6 to slide. The tamping system comprises a barge 9, a rammer 1 and a rammer lifting mechanism 10, the rammer lifting mechanism 10 can lift the rammer 1 to a certain height and then put it down, the rammer 1 moves under the action of gravity until it hits the underwater block stone bed, and under the drive of the hydraulic drive mechanism 13, the rammer lifting mechanism 10 slides on the two guide rails 11, and the position of the rammer 1 can be adjusted as needed, thereby adjusting the tamping point position of the rammer 1, and the positioning of the tamping point is very convenient, ensuring the construction quality, and the tamping efficiency is high.

[0036] As a preferred solution, the guide rail 11 is an I-beam, and a sliding mechanism is provided at the bottom of the machine base 6 , which enables the machine base 6 to slide on the guide rail 11 more smoothly.

[0037] like Figure 2 As shown, in this embodiment, the sliding movement mechanism includes two groups of left sliding movement components 17 and two groups of right sliding movement components 18. The two groups of left sliding movement components 17 are arranged at the left end of the base 6, and the two groups of left sliding movement components 17 are respectively arranged on the two guide rails 11 at the left end of the base 6. The two groups of right sliding movement components 18 are arranged at the right end of the base 6, and the two groups of right sliding movement components 18 are respectively arranged on the two guide rails 11 at the right end of the base 6. The hydraulic drive mechanism 13 includes Two push hydraulic cylinders 20 and two clamping assemblies 19, the two push hydraulic cylinders 20 are arranged at the right end of the machine base 6, and the two push hydraulic cylinders 20 correspond to the two right sliding dynamic assemblies 18 one by one, the movable rod of the push hydraulic cylinder 20 is connected to the right sliding dynamic assembly 18, the fixed part of the push hydraulic cylinder 20 is hinged to the right end of the machine base 6, and the clamping assembly 19 is arranged in the right sliding dynamic assembly 18, and the clamping assembly 19 is used to lock the right sliding dynamic assembly 18 and fix it on the guide rail 11. The clamping assembly 19 locks the right sliding dynamic assembly 18 and fixes it on the guide rail 11, and the two push hydraulic cylinders 20 use this as a fixed support point to push or pull the machine base 6. It can be set according to the PLC program. After each tamping point is hit, the hydraulic push-pull rod moves once, and the cylinder stroke is 50cm, and there is no need to manually scale the guide rail 11.

[0038] like Figure 5 As shown, in this embodiment, the clamping assembly 19 includes two clamping hydraulic cylinders 21 arranged opposite to each other and a vertically arranged pressing hydraulic cylinder 22, and a clamping plate 23 is arranged on the movable rods of the two clamping hydraulic cylinders 21 and the pressing hydraulic cylinder 22. The two clamping hydraulic cylinders 21 arranged opposite to each other drive the clamping plates 23 to move toward each other until they press against the two outer side surfaces of the guide rail 11, and the pressing hydraulic cylinder 22 drives the clamping plates 23 to move downward until they press against the top surface of the guide rail 11, and the right sliding motion assembly 18 is locked on the guide rail 11 by clamping the three sides of the guide rail 11.

[0039] like Figure 3-4 As shown, in this embodiment, the left sliding motion component 17 or the right sliding motion component 18 includes a reverse buckle seat 14, and two guide wheels 25 that are arranged opposite to each other and can rotate around their own axes are arranged in the reverse buckle seat 14, and the outer side surfaces of the two guide wheels 25 are in contact with the two outer side surfaces of the guide rail 11. The structure in which the outer side surfaces of the guide wheels 25 are in contact with the two outer side surfaces of the guide rail 11 enables the base 6 to slide on the guide rail 11 more steadily and smoothly. During the sliding process of the base 6, the guide wheels 25 can rotate around their own axes. There is sliding friction between the guide wheels 25 and the boss, and the friction between the two is smaller, which can reduce the wear between the two and increase the service life.

[0040] like Figure 1As shown, in this embodiment, the lifting and tamping mechanism 10 also includes a main engine boom 3, a lifting wire rope 2 and a hoisting winch 5. The lower end of the main engine boom 3 is connected to the machine base 6, the inner end of the lifting wire rope 2 is fixedly connected to the hoisting winch 5, the outer end of the lifting wire rope 2 is fixedly connected to the tamping hammer 1, and the middle part of the lifting wire rope 2 is slidably connected to the upper end of the main engine boom 3. The lifting wire rope 2 can be retracted or released by the hoisting winch 5, so as to lift or lower the tamping hammer 1, and the upper end of the main engine boom 3 supports the lifting wire rope 2.

[0041] like Figure 1 As shown, in this embodiment, the lower end of the main engine boom 3 is hinged to the machine base 6, and the tamping system further includes a support rod 4, the upper end of which is hinged to the main engine boom 3, and the lower end of which can be horizontally moved relative to the machine base 6 and positioned on the machine base 6. The main engine boom 3 and the support rod 4 form a variable amplitude mechanism, which moves the lower end of the support rod 4 in the horizontal direction, and the upper end of the support rod 4 can pull the main engine boom 3 to swing, so that the upper end of the main engine boom 3 moves in the horizontal direction, thereby driving the rammer 1 to move in the horizontal direction. This structure can more conveniently adjust the tamping point position of the rammer 1 and improve the accuracy of the tamping point position adjustment.

[0042] like Figure 6 As shown, in this embodiment, a luffing beam 7 extending in the horizontal direction is fixed on the machine base 6, and a plurality of sockets 7a distributed in the horizontal direction are provided on the luffing beam 7. A hoop 8 is hingedly connected to the lower end of the support rod 4, and the hoop 8 is fixed to the luffing beam 7 by a latch. In this structure, under the traction of a traction device such as a luffing winch, the hoop 8 is moved along the luffing beam 7 to achieve luffing, and the hoop 8 is fixed to the luffing beam 7 by a latch to achieve positioning of the lower end of the support rod 4.

[0043] Embodiment 2

[0044] like Figure 7 As shown, the structure and principle of this embodiment are basically the same as those of the first embodiment, except that a screw rod 15 extending in the horizontal direction is fixed on the machine base 6, a hoop 8 is hinged at the lower end of the support rod 4, the hoop 8 is threadedly connected to the screw rod 15, and a first drive motor 16 for driving the screw rod 15 to rotate is fixed on the machine base 6. In this structure, the screw rod 15 is rotated under the drive of the first drive motor 16, so that the hoop 8 moves in the horizontal direction to achieve amplitude change.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
