Description

Intelligent dock bridge for loading and unloading containers

Technical Domain

The invention relates to the technical field of container cranes. More specifically, the present invention relates to an intelligent quay bridge for loading and unloading containers.

Prior art

Quay cranes, also known as quay container cranes, are equipment used to load and unload containers on container ships at the quay. In order to reduce the cost of goods in maritime traffic and load more goods on board, container ships have been upgraded from the third-generation 2500 TEU Panama-type container ships to the fourth-generation, fifth-generation and sixth-generation 7000 TEU container ships, with the acceleration of large-scale speed, to the current era of 10,000 TEU container ships.

Quay bridges are mainly a type of fixed rear beams and are constructed in such a way that in the operating state (operating conditions for loading and unloading containers), the front beam is horizontally connected to the rear beam, and in the non-operating state (including non-operating conditions and storm conditions), the front beam is lifted. According to the wheel pressure distribution of conventional quay bridges, the existing quay bridges have a large wheel pressure on the sea side in the operating state and a large wheel pressure on the land side in the non-operating state. With the improvement of loading and unloading capacity, the wheel pressure of the quay bridge also increases.

In the prior art, for most types of beam structures, solid web box-shaped beam structures are used. The solid web box-shaped structural beams are mainly square cubes or cubic column structures. The quay bridges with solid web beams are not only heavy and energy-consuming, but also due to the large windward area of the solid web beams, the wind load on the quay bridge is large, which has a negative impact on the overall structure of the quay bridge, and at the same time also produces a larger operating wheel pressure. Therefore, with the improvement of the loading and unloading capacity, the wind resistance also needs to be further improved.

In order to achieve these and other purposes according to the present invention, an intelligent quay bridge for loading and unloading containers is provided, comprising: . a quay bridge body, . a pair of oblique support structures, each oblique support structure comprising an oblique strut, connecting ends rotatably arranged at both ends of the oblique strut, and a pair of connecting seats diagonally arranged oppositely on a rectangular frame formed by a sea-side column and a land-side column of the quay bridge body, the both connecting ends being movably connected to the pair of connecting seats, 20 . a windbreak structure, which comprises a plurality of windbreak units respectively arranged on a front beam and a rear beam of the quay bridge body, each of the windbreak units comprising: . a base, which is arranged on the front beam or the rear beam, 25 . a universal telescopic member, which is disposed inside the base, the universal telescopic member being driven by a drive member to rotate and stretch, . a spindle having a lower end disposed on the universal telescopic member, the spindle being provided with a limit cap, 30 . a damping member, which is movably sleeved on the spindle along the axial direction of the spindle, and . a wind blade, which has an inverted cone shape, the wind blade being movably sleeved on the spindle and being located between the limit cap and the damping member.

Preferably, the pair of connecting seats has a connecting cavity therein, a bottom of the connecting cavity is arc-shaped, and the connecting cavity is filled with rubber particles, and one end of the connecting ends is a bearing and is fixed to the oblique spacer, and the other end of the connecting ends is spherical and extends into the connecting cavity to abut against the bottom of the connecting cavity.

Preferably, the base has the shape of a truncated cone with a small upper portion and a large lower portion, and the sides of the longitudinal cross-section of the base are in the form of an arc of a circle hollowed out at the center.

Preferably, the universal telescopic element comprises four electric cylinders distributed in a rectangle, four first springs whose lower ends are respectively fixed to the movable ends of the four electric cylinders, and a mounting plate fixed to the upper ends of the first four springs, the pin being fixed to the mounting plate.

Preferably, the spindle is provided along itself in an opposing manner with a pair of channels parallel to the axial direction of the spindle, and the damping member comprises a pair of spring plates sleeved on the spindle and a second spring, both ends of which are respectively fixed to the pair of spring plates, the spring plates being provided at their side wall with transverse threaded through holes into which a bolt, one end of which extends into the channels, is respectively screwed.

Preferably, a top of the boundary cap is spherical in shape.

The present invention comprises at least the following beneficial effects.

Firstly, the oblique support structure of the present invention still adopts a stable structure forming a triangle, but the connecting end is provided at the connecting place, which allows a certain degree of freedom of movement, cushioning the pressure and releasing the torque constraints, and ultimately greatly reducing the wheel pressure, thereby adapting to the needs of improving the loading and unloading capacity of the quay bridge.

Secondly, the bearing provides a relative rotational degree of freedom between the connecting end and the oblique spacer, the adaptation of the arc shape at the bottom of the connecting cavity to the spherical shape of the connecting end provides a sliding degree of freedom between the connecting end and the connecting seat, and the filled rubber particles have the effect of limiting and damping the sliding distance and sliding speed between the connecting end and the connecting seat, which can not only ensure the stability between the sea-side column, the land-side column and the oblique support structure, but also play a role in pressure cushioning and torque stress release, thereby ultimately significantly reducing the wheel pressure.

Third, according to the present invention, the wind blade is designed as an inverted cone-shaped structure, which realizes that when the wind blade rotates under the action of the wind, it will always produce a downward force, which acts on the second spring, and finally acts on the front beam or the rear beam through the force transmission, thereby improving the stability of the entire quay bridge. By combining with the universal telescopic member, the angle of the wind blade can be changed according to the current wind direction and the condition of the quay bridge (the angle between the front beam and the rear beam), and the stability maintaining effect of the wind blade can be further improved.

Other advantages, objects and features of the present invention will become apparent in part from the description which follows, and in part will be understood by those skilled in the art through investigation and practice of the present invention.

As shown in FIGS. 1 to 3, the interpretation of the drawings in the description of the present invention is as follows: sea-side column 1, land-side column 2, front beam 3, rear beam 4, oblique support structure 100, oblique spacer 11, connecting end 12, connecting seat 13, connecting cavity 14, rubber particles 15, rubber layer 16, windproof structure 200, base 21, universal telescopic member 22, pin 23, limit cap 24, damping member 25, wind blade 26, electric cylinder 201, first spring 202, mounting plate 203, spring plate 204, second spring 205, bolt 206, annular blade 27.

As shown in Figures 1 to 3, the present invention provides an intelligent quay bridge for loading and unloading containers, comprising: . a quay bridge body, which is a common quay bridge in the prior art, with a front beam 3, a rear beam 4, a seaside column 1 and a landside column 2, . a pair of oblique support structures 100, each oblique support structure 100 comprising an oblique strut 11, connecting ends 12 rotatably arranged at both ends of the oblique strut 11, and a pair of connecting seats 13 diagonally arranged oppositely on a rectangular frame formed by a sea-side column 1 and a land-side column 2 of the quay bridge body, the two connecting ends 12 being movable connected to the pair of connecting seats 13. In the prior art, connecting columns are fixedly diagonally arranged between the sea-side column 1 and the land-side column 2 of the quay bridge, forming two triangular fixed structures, which can improve the stability of the connection between the sea-side column and the land-side column 2, but with the improvement of the loading and unloading capacity, the fixed connecting structure cannot buffer the pressure and torque stress, resulting in an increase in the wheel pressure, which is not conducive to the safety of the quay bridge. The oblique support structure 100 of the present invention still adopts a stable structure forming a triangle, but the connecting end 12 is provided at the connecting place, which allows a certain degree of freedom of movement, cushioning the pressure and releasing the torque constraints, and ultimately greatly reducing the wheel pressure, thereby adapting to the needs of improving the loading and unloading capacity of the quay bridge.

In particular, the pair of connecting seats 13 has a connecting cavity 14 therein, a bottom of the connecting cavity 14 is arc-shaped, and the connecting cavity 14 is filled with rubber particles 15, one end of the connecting ends 12 is a bearing and is fixed to the oblique spacer 11, and the other end of the connecting ends 12 is spherical and extends into the connecting cavity 14 to abut against the bottom of the connecting cavity 14.

The bearing provides a relative rotational degree of freedom between the connecting end 12 and the oblique spacer 11, the adaptation of the arc shape at the bottom of the connecting cavity 14 to the spherical shape of the connecting end 12 provides a sliding degree of freedom between the connecting end 12 and the connecting seat 13, and the filled rubber particles 15 have the effect of limiting and damping the sliding distance and sliding speed between the connecting end 12 and the connecting seat 13, which can not only ensure the stability between the sea-side column 1, the land-side column 2 and the oblique support structure 100, but also play a role in buffering pressure and releasing torque stress, thereby ultimately significantly reducing the wheel pressure.

In particular, a rubber layer 16 is applied at an opening of the connecting cavity 14 to reduce the abrupt collision between the connecting end 12 and the connecting cavity 14;

. a windbreak structure 200, which comprises a plurality of windbreak units respectively arranged on a front beam 3 and a rear beam 4 of the quayside bridge body.

The position of the windbreak units is arranged according to the stress support points of the front beam 3 and the rear beam 4 of each quay deck, the specific arrangement being the best position near the stress support point.

Each windproof unit includes:

. a base 21, which is arranged on the front beam 3 or the rear beam 4, and which is intended to be used for installing and fixing the main components of the windbreak assembly.

In particular, the base 21 has the shape of a truncated cone with a small upper part and a large lower part, and the sides of the longitudinal cross-section of the base 21 are in the form of an arc of a circle hollowed out in the center.

Base 21 is mounted and fixed on the front beam 3 or the rear beam 4. Base 21 is at altitude and is strongly affected by the wind.

The outer contour designed to be arc-shaped has a wind guide downwind, thereby reducing the effect of being affected by wind;

. a universal telescopic element 22, which is arranged inside the base 21, the universal telescopic element 22 being driven by a drive element to rotate and stretch.

The universal telescopic element 22 has some upward and downward mobility in four positions, front, rear, left and right.

In particular, the universal telescopic element 22 comprises four electric cylinders 201 distributed in a rectangle, four first springs 202 whose lower ends are respectively fixed to the movable ends of the four electric cylinders 201, and a mounting plate 203 fixed to the upper ends of the first four springs 202.

Four electric cylinders 201 constitute the driving element. If one of the electric cylinders 201 is started, the corresponding position of the mounting plate 203 is driven to rise or fall. With the cooperation of the four electric cylinders 201, the mounting plate 203 can be made to be left high and right low, left low and right high, front high and rear low, front low and rear high, and different angles obtained by the combination of different states, as well as a horizontal state; . a pin 23 of which a lower end is arranged on the universal telescopic member 22, the pin 23 being provided with a limit cap 24. In particular, the pin 23 is fixed to the mounting plate 203. In particular, the top of the limit cap 24 is spherical, and the outer contour designed to be spherical has a wind guide downwind, thereby reducing the effect of being affected by wind; . a damping member 25, which is movably sleeved on the pin 23 along the axial direction of the pin 23, and which is intended to be used for transmitting the force of the wind blade 26. In particular, the pin 23 is provided along itself in an opposite manner with a pair of channels parallel to the axial direction of the pin 23. The damping member 25 comprises a pair of spring plates 204 sleeved on the pin 23 and a second spring 205, both ends of which are respectively fixed to the pair of spring plates 204, the spring plates 204 being provided at their side wall with transverse threaded through holes onto which a bolt 206, one end of which extends into the channels, is respectively screwed. When the damping member 25 is subjected to downward pressure, it will compress the spring plate 204 at the upper end, the spring plate 204 at the upper end compresses the second spring 205, the second spring 205 then continues to transmit the applied force to the spring plate 204 at the lower end, the force finally acts on the front beam 3 or the rear beam 4, thereby improving the stability of the entire dock bridge. The arrangement of the chutes can limit the sliding of the spring plate 204 up and down only in the direction of the pin 23 without rotation. a wind blade 26, which has an inverted cone shape, the wind blade 26 being movably sleeved on the pin 23 and being located between the limit cap 24 and the damping member 25. By designing an inverted cone-shaped structure, it can be realized that when the wind blade 26 is rotated by the wind, it will always produce a downward force, thereby acting on the second spring 205, and finally acting on the front beam 3 or the rear beam 4 by transmitting the aforementioned force, thereby improving the stability of the entire quayside bridge. By combining with the universal telescopic member 22, the angle of the wind blade 26 can be changed according to the current wind direction and the condition of the quayside bridge (the angle between the front beam 3 and the rear beam 4), and the stability maintaining effect of the wind blade 26 can be further improved. In particular, the base 21 is open at its top, and an open portion of the base 21 is sealingly connected to the spring plates 204 located at the upper end via an annular blade 27, which is corrugated and is both flexible and elastic. The annular blade 27 has a waterproof effect to protect the internal components of the base 21 from rain erosion, and it will not affect the operation of the internal components of the base 21.

In the above-mentioned technical solution, when the quayside bridge loads containers, etc. or the container moves on the quay deck (driven by the quay deck trolley), the wheel pressure of the quay deck will increase significantly, but under the action of the oblique support structure 100, the bearing provides a relative rotational degree of freedom between the connecting end 12 and the oblique spacer 11, the adaptation of the arc shape at the bottom of the connecting cavity 14 to the spherical shape of the connecting end 12 provides a sliding degree of freedom between the connecting end 12 and the connecting seat 13, and the filled rubber particles 15 have the effect of limiting and damping the sliding distance and sliding speed between the connecting end 12 and the connecting seat 13, which can not only ensure the stability between the sea-side column 1, the land-side column 2 and the oblique support structure 100,

but also play a role in pressure damping and torque stress release, thereby ultimately significantly reducing wheel pressure.

When the quayside bridge is affected by wind (especially wind with high wind levels), it will have an impact on the coastal bridge and affect the stability of the quayside bridge. For example, when the quayside bridge is subjected to a side wind (perpendicular to the direction from the sea side to the land side), it directly affects the front beam 3 and the rear beam 4, which have a large force area and have the greatest impact on the stability. However, when the windbreak structure 200 is set up, the greater the wind, the greater the rotation speed of the wind blade 26, and the greater the downward force generated, it can act downward on the spring plate 204, be transmitted through the second spring 205, and finally act on the quayside bridge. When the rotation speed of the wind blade 26 reaches a certain value, the second spring 205 is forcibly compressed and finally acts on the quayside bridge. In both cases, the side wind can be converted into a downward force and applied to the quay bridge, which is equivalent to increasing the weight of the quay bridge, thereby improving the windproof capacity and stability of the quay bridge. Due to the changes in the wind direction of the port throughout the year, by combining with the universal telescopic member 22, the direction of the pin 23 can be adjusted, thereby adjusting the direction of the rotation center of the wind blade 26, so that the wind effect is maximally converted into the stabilizing effect of the quay bridge.

Although the embodiments of the present invention have been described above, they are not limited to the applications listed in the specification and implementations, and can be fully applied to various fields suitable for the present invention, and further modifications can be easily implemented by those skilled in the art. Therefore, the present invention is not limited to the specific details and illustrations shown and described herein without departing from the general concept defined by the claims and by the equivalent scope.
