Description

Grab bucket device with shallow point auxiliary recognition function

Technical Field

The utility model belongs to the technical field of dredging construction equipment, and particularly relates to a grab bucket device with a shallow point auxiliary identification function.

Background

The grab ship is mainly applied to projects such as river channel dredging, wharf construction, sediment loading and transporting, water heavy object hoisting, water piling and the like, and is generally used for underwater shallow sweeping construction in the projects such as the river channel dredging. The shallow sweeping construction refers to a construction process of excavating and leveling a water bottom mud surface by removing soil at a water bottom high point position, so that the elevation of a river bottom (sea bottom) is ensured to meet the design requirement. The grab bucket ship grabs, promotes and shifts the earth of submarine high point position, reaches the aforesaid purpose of sweeping shallow construction. In the shallow-sweeping construction stage, due to the difference between the size of the shallow point at the bottom of the navigation channel and the soil quality, in the process of shallow-sweeping construction by adopting the grab ship, the phenomena of incomplete shallow-sweeping and the like caused by factors such as missing bucket arrangement or high points of harder soil quality are generated, the shallow-sweeping efficiency of the grab ship is reduced, the grab ship is frequently subjected to ship moving and anchor moving operation, and the construction cost is improved.

In the process of shallow-sweeping construction, in order to know the mud surface condition at the water bottom and guide the shallow-sweeping construction operation of the grab ship, it is a common means to adopt a water depth measuring instrument to measure the water depth so as to obtain the position data of the water bottom high point in the construction area. However, in the existing construction process, due to factors such as shallow point dispersion, frequent detection and measurement by using a water depth measuring instrument become common operations, however, in the operation of acquiring the position of the shallow point at the water bottom, the time required for measurement and analysis is long, which has a great influence on the shallow point sweeping construction efficiency of the grab ship, wastes time and labor, and reduces the operation efficiency.

The device for assisting shallow point position detection and identification is constructed on the grab bucket device of the grab bucket dredger, so that the condition of the underwater shallow point in the operation area can be sensed and judged in the process of sweeping shallow operation construction of the grab bucket dredger, and the construction operation process can be influenced rapidly and effectively. The prior art does not have the grab bucket device and needs to be developed and designed.

Detailed Description

The principle of the grab bucket device with the shallow point auxiliary identification function is described as follows:

the height design requirement of engineering projects on the mud surface at the bottom of a river (on the bottom of the sea) is difficult to meet due to uneven mud surface at the bottom of the river, the mud surface high points at the bottom of the sea (namely the positions with the actual heights higher than the designed heights) are found in a mode of carrying out shallow sweeping operation by adopting grab dredger facilities, and the silt at the mud surface high points at the bottom of the sea is grabbed above the water surface and transferred to a transport ship for transfer and conveying in a grab grabbing mode. The term "having a shallow point auxiliary recognition function" in the name of the present invention means having a function of recognizing points (positions) requiring a shallow sweeping operation, and as described above, the points (positions) requiring a shallow sweeping operation mean those "high points" on the bottom mud surface.

In order to further understand the contents, features and effects of the present invention, the following embodiments are described in detail.

Referring to fig. 1 and 2, the grab bucket device with shallow spot auxiliary recognition function of the present invention includes an upper base 2 having a fixed pulley 11 mounted at the bottom thereof and a lower base 13 having a movable pulley 4 mounted at the top thereof, in this embodiment, a pulley base 5 is mounted at the top of the lower base 13, and the movable pulley 4 is mounted on the pulley base 5.

In this embodiment, a lifting lug 1 for hanging is provided at the top center of the upper base 2. The suspension cable of the grab dredger is connected with the lifting lug 1, so that the grab dredger is integrally hung below the suspension cable, and the dredger facilities realize the lowering and lifting operation of the grab dredger by controlling the retraction and release of the suspension cable. The steel cable of another set of lifting system of the grab dredger passes through a cable hole formed in the upper base 2 and then winds between the fixed pulley 11 and the movable pulley 4 to form a pulley block, and the opening and closing of the grab are controlled by controlling the winding and unwinding of the steel cable.

The lower base 13 is hinged with a left grab bucket 8 and a right grab bucket 15 which can be opened and closed, specifically, hinged shafts 6 are arranged in the middle of the front surface and the middle of the back surface of the lower base 13, the upper parts of the front surfaces of the left grab bucket 8 and the right grab bucket 15 are hinged with the lower base 13 through the hinged shafts 6 on the front surfaces, and the upper parts of the back surfaces of the left grab bucket 8 and the right grab bucket 15 are hinged with the lower base 13 through the hinged shafts 6 on the back surfaces.

A left connection base 7 is mounted on the outer side of the left grab 8, a right connection base 14 is mounted on the outer side of the right grab 15, a left arm 3 is mounted between the left portion of the upper base 2 and the left connection base 7, and a right arm 12 is mounted between the right portion of the upper base 2 and the right connection base 14. Specifically, the upper ends of both the left and right side arms 3 and 12 are hingedly connected to the upper base 2, and the lower ends are hingedly connected to the left and right connection bases 7 and 14, respectively.

In this embodiment, the left bucket tooth 9 is installed on the bottom lip of the left grab bucket 8, the right bucket tooth 16 is installed on the bottom lip of the right grab bucket 15, the left bucket teeth 9 and the right bucket teeth 16 are arranged in a staggered manner, and when the left grab bucket 8 and the right grab bucket 15 are buckled, the left bucket teeth 9 and the right bucket teeth 16 are meshed, so that the bottom closure of the whole closed grab bucket device can be ensured.

A plurality of shallow point identification assemblies 10 are arranged between the left grab bucket 8 and the right grab bucket 15, the shallow point identification assemblies 10 are used for identifying 'high points' needing shallow sweeping operation on the underwater mud surface, and the grab bucket device is adopted for shallow sweeping operation construction after identification. The shallow point identification component 10 comprises a steel wire rope 10-6, and two ends of the steel wire rope 10-6 are detachably connected with the left grab bucket 8 and the right grab bucket 15 respectively.

The principle is as follows: when the grab bucket device is in an open state, the steel wire rope 10-6 is straightened; the grab bucket device is lowered onto a water bottom mud surface, the grab bucket device is transversely dragged to move in a translation mode on the water bottom mud surface, when the steel wire rope 10-6 is scratched to a high point protruding from the water bottom mud surface, the resistance of the grab bucket device is increased and is reflected in a control room of a grab dredger facility, an operator can read the change of the transverse movement moment of the grab bucket device from an instrument, the judgment that the high point needing shallow sweeping operation exists at the current position is made, and therefore the auxiliary identification of the position needing shallow sweeping operation is achieved.

Referring to fig. 1 and 3, it can be seen that:

the shallow point identification assembly 10 comprises two connecting shafts 10-4 which are fixedly connected with the left grab bucket 8 and the right grab bucket 15 respectively, and the root parts of the connecting shafts 10-4 are fixedly welded with the left grab bucket 8 and the right grab bucket 15. In this embodiment, the two connecting shafts 10-4 of the shallow point identification assembly 10 are fixedly installed on the same side portions of the left grab bucket 8 and the right grab bucket 15.

The connecting device also comprises two wedge-shaped outer sleeves 10-3 with connecting lug plates 10-1, shaft holes are arranged on the connecting lug plates 10-1, and the connecting shafts 10-4 are positioned in the shaft holes of the corresponding connecting lug plates 10-1 and locked by adopting pins 10-2. The wedge-shaped block 10-5 is arranged in the wedge-shaped outer sleeve 10-3, and the end part of the steel wire rope 10-6 bypasses the corresponding wedge-shaped block 10-5 and is clamped in the wedge-shaped outer sleeve 10-3 together with the wedge-shaped block 10-5. In the embodiment, the wedge-shaped block 10-5 is provided with a rope groove for the steel wire rope 10-6 to fall into, and the rope groove is arranged to position the steel wire rope 10-6 conveniently and prevent the steel wire rope from deviating from the wedge-shaped outer sleeve 10-3.

The connecting lug plate 10-1 and the wedge-shaped outer sleeve 10-3 can be integral castings, and the structural strength is guaranteed. Because the connecting shaft 10-4 is positioned in the shaft hole of the connecting lug plate 10-1, the whole combination body formed by the connecting lug plate 10-1 and the wedge-shaped outer sleeve 10-3 can rotate by taking the connecting shaft 10-4 as the center, so that the problem that the steel wire rope is blocked or the steel wire rope is repeatedly bent and easily broken in the repeated opening and closing action process of the grab bucket device is avoided.

The wedge-shaped block 10-5 and the steel wire rope 10-6 are clamped in the wedge-shaped outer sleeve 10-3, and the steel wire rope 10-6 further pulls the wedge-shaped block 10-5 along with the opening and closing actions of the grab bucket device, so that the end part of the wedge-shaped block is more tightly combined with the wedge-shaped block 10-5 and the wedge-shaped outer sleeve 10-3, the end part of the steel wire rope 10-6 is less prone to being separated, and the reliability is high.

When the steel wire rope 10-6 needs to be replaced, tools such as a steel bar and a hammer can be adopted, the wedge-shaped block 10-5 is reversely taken out from the wedge-shaped outer sleeve 10-3 from inside to outside, and the steel wire rope is re-clamped after a new steel wire rope 10-6 is replaced, so that the maintenance operation is convenient and labor-saving.

As mentioned above, the shallow point identification assemblies 10 can be arranged in a plurality of sets, and fig. 1 and 4 show that only one set of shallow point identification assemblies 10 is arranged at the front, it is conceivable that more sets of shallow point identification assemblies 10 can be arranged according to actual requirements, and in general, each set of shallow point identification assemblies 10 can be positioned between the bottom lips and the side portions close to the tip of both the left grab bucket 8 and the right grab bucket 15 (the case shown in fig. 1).

It should be noted that the shallow point identification module 10 is only used to assist in identifying and determining the position of the bottom mud surface where the shallow sweeping operation is required, and is not used to guide the degree of the shallow sweeping operation (i.e., the degree of operation of the grapple attachment at the same position where the shallow sweeping operation is performed) which is controlled on site by the grapple dredger installation.

The working process is as follows:

welding and installing the connecting shaft 10-4 of the shallow point identification assembly 10 at corresponding positions on the left grab bucket 8 and the right grab bucket 15; the shallow point auxiliary identification operation is required to be carried out, the steel wire rope 10-6 with the proper length is obtained through cutting, two end parts of the steel wire rope 10-6 respectively penetrate through the two wedge-shaped outer sleeves 10-3, and after the steel wire rope is wound on the rope groove of the wedge-shaped block 10-5, the wedge-shaped block 10-5 and the end part of the steel wire rope 10-6 are embedded into the wedge-shaped outer sleeve 10-3 and are clamped tightly; then connecting the connecting ear plate 10-1 on the corresponding wedge-shaped outer sleeve 10-3 with the connecting shaft 10-4 and locking by adopting a pin 10-2; the installation of the shallow point identification assembly 10 is now complete;

the dredger facility controls the grab bucket device to be fully opened, so that the steel wire rope 10-6 is straightened and is in a proper tensioning state; the dredger facilities lay the cable to the suspension cable, and the whole grab bucket device is lowered to the water bottom, which can be seen in fig. 4;

the dredger facility controls the suspension arm of the grab bucket device to move transversely, and correspondingly, the grab bucket device in an open state is dragged to move under the water; on a moving path, when a mud surface high point needing shallow sweeping operation exists, the steel wire rope 10-6 of the shallow point identification assembly 10 and the mud surface high point at the position are scratched, and moving resistance is increased; an operator judges that the current grab bucket device passes through the mud surface high point needing shallow sweeping operation through the meter reading and operation experience, the current shallow point identification process is stopped, and the shallow sweeping operation process is started, namely the grab bucket device is operated to grab and transfer the mud surface high point at the position until the mud surface high point at the position is removed; and repeating the shallow point identification operation and the shallow point sweeping operation to finish the shallow point sweeping operation construction in a certain area.
