Description

Technical Field

[0001] The present invention relates to the technical field of anti-wind safety devices for cranes, and particularly to a self-connecting and interlocking device for cranes. Background Art

[0002] There are a large number of goods to be hoisted and transported at port terminals. Currently, cranes are used to hoist the goods, and there are multiple cranes operating on the same track at the same time. In the event of a sudden strong wind at the terminal, multiple cranes on the same track need to be individually anchored. However, the anti-wind effect of individually anchoring the cranes is poor, and serious safety problems are likely to occur. Summary of the Invention

[0003] The purpose of the present invention is to provide a self-connecting and interlocking device for cranes to solve at least one of the above problems existing in the prior art.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A self-connecting and interlocking device for cranes includes a first interlocking device. The first interlocking device includes a first mounting seat, a ratchet wheel, a hook, and a ratchet trigger device. The first mounting seat is used for fixedly connecting with the crane. The ratchet wheel is rotatably connected to the first mounting seat. One end of the hook is rotatably connected to the first mounting seat. The ratchet wheel is located behind the hook. A pulling rope is wound around the rotating shaft of the ratchet wheel, and the end of the pulling rope is connected to the other end of the hook. The ratchet trigger device includes a braking pawl and a pawl driving component for driving the braking pawl to disengage from the ratchet wheel. The rotating shaft of the ratchet wheel rotates counterclockwise to wind up the pulling rope, and the braking pawl is used to limit the clockwise rotation of the ratchet wheel.

[0006] In this technical solution, by rotating the ratchet wheel counterclockwise, the rotating shaft of the ratchet wheel winds up the pulling rope to realize the pulling of the hook. The hook is in a lifted state, and the first interlocking device can be docked with the second interlocking device. During the process of the first interlocking device and the second interlocking device moving towards each other, the pawl driving component is triggered, and the pawl driving component drives the braking pawl to disengage from the ratchet wheel. Since the pulling rope is wound around the rotating shaft of the ratchet wheel and the other end of the pulling rope is connected to the hook, under the action of the gravity of the hook, the pulling rope will drive the ratchet wheel to rotate clockwise, thereby realizing the release of the pulling rope. At the same time, the hook also rotates from the lifted state to the state of being hooked to the corresponding hook groove of the second interlocking device. This design enables the first interlocking device to cooperate with the second interlocking device to connect multiple cranes on the same track to each other to form an integrated body to resist the influence of strong winds, thereby improving the safety of the cranes in a strong wind environment.

[0007] Of course, when possible, the corresponding hook grooves and trigger blocks can also be directly installed on the adjacent crane, and the interconnection effect with the adjacent crane can also be achieved only through the cooperation of the first interlocking device with a simple hook groove and the corresponding trigger block.

[0008] Furthermore, the first interlocking device further includes a first telescopic device, which is arranged on the first mounting seat. The first mounting seat has a length direction X, and the extending direction of the first telescopic device is parallel to the direction X. Since the first interlocking device has the first telescopic device, it can play a role in buffering the docking during the docking process with the adjacent second telescopic device, and can cooperate with the adjacent second telescopic device to automatically connect two adjacent cranes on the same track into one body.

[0009] Furthermore, in order to better trigger the braking pawl, simplify the structural design and facilitate assembly, the pawl driving assembly includes a trigger rod, which is horizontally slidably connected to the first mounting seat. The middle part of the braking pawl is rotatably connected to the first mounting seat, the lower end of the braking pawl is movably connected to one end of the trigger rod, the upper end of the braking pawl abuts against the braking surface of the ratchet tooth, the other end of the trigger rod is the trigger end, and the trigger end extends out of the first mounting seat.

[0010] Furthermore, in order to provide a first base with a stable structure and convenient for matching and installing various components, the first mounting seat includes a first base and first extension arms symmetrically arranged on both sides of the first base. The first telescopic device is located between the two first extension arms. One end of the first telescopic device is fixedly connected to the first base. There is a first fixing device for fixing the first telescopic device between the two first extension arms. The free end of the first telescopic device extends out of the free end of the first extension arm. The hook is arranged at a position close to the free end of the first extension arm, and the ratchet is arranged at a position close to the first base.

[0011] Furthermore, in order to facilitate the rotation operation of the ratchet, the ratchet is connected with a rotation handle. Of course, it can also be other automatic driving methods.

[0012] Furthermore, in order to achieve a more stable interconnection effect, hooks are rotatably connected to both first extension arms. Two pull ropes are respectively wound around the rotation shaft of the ratchet. The end parts of the two pull ropes are respectively connected to the two hooks.

[0013] Furthermore, in order to more stably install the rotation shaft of the ratchet, mounting brackets are respectively arranged on the two first extension arms, and the rotation shaft of the ratchet is rotatably connected to the mounting brackets.

[0014] Further, to facilitate the winding of the pulling rope, a winding wheel is provided on the rotating shaft of the ratchet wheel, and the pulling rope is wound around the winding wheel. Specifically, the pulling rope can be a steel wire or a chain.

[0015] Further, to achieve a better interconnection and adaptation effect with the first interlocking device, a second interlocking device is further included. The second interlocking device includes a second mounting seat and a trigger block. The second mounting seat is used for fixedly connecting with the crane, and the trigger block is used for driving the pawl driving assembly. A hook groove is provided on the second mounting seat. After the first interlocking device and the second interlocking device are docked, the hook is hooked with the hook groove.

[0016] Further, to have a better buffering effect between the first interlocking device and the second interlocking device during the interlocking docking process, the second interlocking device further includes a second telescopic device. The second telescopic device and the trigger block are both arranged on the second mounting seat. The second mounting seat has a length direction X, the extending direction of the second telescopic device is parallel to the direction X, and the second telescopic device abuts against the first telescopic device.

[0017] Further, to provide a second base with a stable structure and convenient for matching and installing various components, the second mounting seat includes a second base and second extension arms symmetrically arranged on both sides of the second base. The second telescopic device is located between the two second extension arms. One end of the second telescopic device is fixedly connected to the second base. A second fixing device for fixing the second telescopic device is provided between the two second extension arms. The free end of the second telescopic device extends out of the free end of the second extension arm. The hook groove is arranged at a position close to the free end of the second extension arm. To achieve a more stable buffering effect, both the first telescopic device and the second telescopic device are buffer cylinders.

[0018] The beneficial effects of the present invention are as follows: In this technical solution, by rotating the ratchet wheel counterclockwise, the rotating shaft of the ratchet wheel winds up the pulling rope to realize the pulling of the hook. The hook is in a lifted state. The first interlocking device can be docked with the second interlocking device. During the process of the first interlocking device and the second interlocking device moving towards each other, the pawl driving assembly is triggered, and the pawl driving assembly drives the braking pawl to disengage from the ratchet wheel. Since the pulling rope is wound around the rotating shaft of the ratchet wheel and the other end of the pulling rope is connected to the hook, under the action of the gravity of the hook, the pulling rope will drive the ratchet wheel to rotate clockwise, thereby realizing the release of the pulling rope. At the same time, the hook also rotates from the lifted state to the state of being hooked with the hook groove corresponding to the second interlocking device. This design can connect multiple cranes on the same track with each other through the cooperation of the first interlocking device and the second interlocking device to form an integral body to resist the influence of strong winds, thereby improving the safety of the crane in a strong wind environment.

Detailed implementation

[0024] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the present invention in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention.

[0025] Embodiment 1:

[0026] As Figures 1 - 4 shown, this embodiment provides a self - connecting interlocking device for a crane, including a first interlocking device. The first interlocking device includes a first mounting seat, a first telescoper 1, a ratchet 2, a hook 3 and a ratchet trigger device. The first mounting seat is used for fixedly connecting with the crane. The first telescoper 1 is arranged on the first mounting seat. The first mounting seat has a length direction X, and the extending direction of the first telescoper 1 is parallel to the direction X. The ratchet 2 is rotatably connected to the first mounting seat. One end of the hook 3 is rotatably connected to the first mounting seat. The ratchet 2 is located behind the hook 3. A pulling rope 5 is wound around the rotating shaft 4 of the ratchet 2, and the end of the pulling rope 5 is connected to the other end of the hook 3. The ratchet trigger device includes a braking pawl 6 and a pawl driving assembly for driving the braking pawl 6 to disengage from the ratchet 2. The rotating shaft 4 of the ratchet 2 rotates counterclockwise to wind up the pulling rope 5, and the braking pawl 6 is used to limit the clockwise rotation of the ratchet 2.

[0027] In this technical solution, since the first interlocking device has a first telescopic device 1, during the docking process with the adjacent second telescopic device 19, it can play a role in buffering the docking, and can cooperate with the adjacent second telescopic device 19 to automatically connect two adjacent cranes on the same track into one body. Specifically, by rotating the ratchet wheel 2 counterclockwise, the rotating shaft 4 of the ratchet wheel 2 winds up the pulling rope 5, realizing the pulling of the hook 3. The hook 3 is in a lifted state. The first interlocking device can be docked with the second interlocking device. During the docking process, the first telescopic device 1 abuts against the second telescopic device 19 of the second interlocking device and is gradually compressed until the pawl driving assembly is triggered. The pawl driving assembly drives the braking pawl 6 to disengage from the ratchet wheel 2. Since the pulling rope 5 is wound around the rotating shaft 4 of the ratchet wheel 2 and the other end of the pulling rope 5 is connected to the hook 3, under the gravity of the hook 3, the pulling rope 5 will drive the ratchet wheel 2 to rotate clockwise, thereby realizing the release of the pulling rope 5. At the same time, the hook 3 also rotates from the lifted state to the state of being hooked to the hook groove 21 corresponding to the second interlocking device. This design can connect multiple cranes on the same track with each other through the cooperation of the first interlocking device and the second interlocking device to form a whole to resist the influence of strong winds, thereby improving the safety of the crane in a strong wind environment.

[0028] Of course, if possible, the corresponding hook groove 21 and trigger block 20 can also be directly installed on adjacent cranes, and the effect of interconnecting with adjacent cranes can also be achieved only through the cooperation of the first interlocking device with the simple hook groove 21 and the corresponding trigger block 20.
