[0004] In the existing storage box for the main hook of a marine derrick crane, a support strip is provided at the bottom. However, in order to ensure the stability of the position of the main hook in the storage box, the bolt contacts the main hook and forms a certain acting force, making it difficult to manually insert and pull out the bolt, and the degree of automation of the plugging and unplugging operation is low. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that in order to ensure the stability of the position of the main hook in the storage box, the bolt of the existing storage box contacts the main hook and forms a certain acting force, making it difficult to manually insert and pull out the bolt, and the degree of automation of the plugging and unplugging operation is low.

[0011] Further, the control board is also provided with an on button and an off button, and the control board is also configured to:

[0012] After the lifting hook enters the box, operate the on button to power on the control board and turn on the pressure sensor; after the pin shaft is inserted in place, operate the off button to power off the control board;

[0013] Before the lifting hook exits the box, operate the on button to power on the control board and turn on the pressure sensor; after the pin shaft is pulled out in place, operate the off button to power off the control board.

[0014] Further, the set pressure is any pressure value between 0 and 0.25t.

[0015] Further, the preloading mechanism is a manual hydraulic jack, and the preloading mechanism has an unloading state and a pressing device. In the unloading state, the pressing part of the preloading mechanism is lower than or flush with the upper end face of the avoidance hole; in the pressing state, the pressing part of the preloading mechanism is higher than the upper end face of the avoidance hole.

[0016] Further, the shape of the surrounding plate is a funnel shape that is wider at the top and narrower at the bottom, and the inner contour of the surrounding plate close to the accommodating cavity is in concave-convex fit with the lifting hook.

[0017] Further, the through hole is arranged in the middle of the side plate, there are two pressure sensors, and the two pressure sensors are symmetrically arranged on both sides of the through hole, and the detected pressure is the sum of the pressures detected by the two pressure sensors.

[0018] Furthermore, a wooden layer is fixed to the inner walls of the two side panels and the enclosure, and bolts are connected between the wooden layer and the side panels and between the wooden layer and the enclosure. The wooden layer is provided with countersunk holes, and nuts are installed in the countersunk holes, and the nuts are threadably matched with the bolts.

[0019] Furthermore, the pin support includes two end plates and two webs, the two end plates are arranged at intervals along the extension direction of the slide groove, the plate surfaces of the two webs are arranged parallel to the extension direction of the slide groove, one web is fixedly connected to the upper parts of the two end plates and fixedly connected to the lower side of the slide groove, and the other web is fixedly connected to the lower parts of the two end plates and fixedly connected to the deck.

[0020] Furthermore, the pin shaft bracket also includes a mounting tube, which is fixedly arranged between the two end plates and fixedly connected to the two webs respectively. The driver is an electric hydraulic push rod, and the driver is inserted into the mounting tube. One of the end plates is provided with a push rod through hole, and a connecting rod is connected between the rod body end of the driver and the pin shaft.

[0021] Furthermore, the upper parts of the two side panels are provided with upper flanges, and the two upper flanges are arranged gradually away from each other from bottom to top, and the upper part of the enclosure is provided with two outer flanges, and the two outer flanges are arranged gradually away from each other from bottom to top.

[0022] Compared with the prior art, the marine lifting hook storage box of the present invention has the following beneficial effects: the marine lifting hook storage box adopts the design form of a storage box body, a pin shaft, a pin shaft bracket, a driver, a pre-lifting mechanism and a control panel, the storage box body includes two spaced side panels and a panel fixedly connected between the two side panels, the two side panels and the panel form a storage cavity with an upper opening. The storage box body can be used for the lifting hook to be placed in the storage cavity, the two side panels and the panel together play a reliable limiting role for the lifting hook, ensuring that the lifting hook can be effectively prevented from shaking and displacement under the bumpy working conditions of the ship.

[0023] Among them, both side plates are provided with through holes, and the two through holes coaxially penetrate the accommodating cavity. The pin shaft bracket is installed on the outside of the storage box body. The pin shaft bracket is provided with a slide groove, which is connected with the through hole. The slide groove and the two through holes form a pin shaft channel extending along the same axis, ensuring the linear motion accuracy of the pin shaft during the insertion and extraction process, and avoiding deflection and jamming. The driver is installed on the pin shaft bracket, and the driver is connected to the pin shaft in a transmission manner. The driver drives the pin shaft to move along the pin shaft channel in a translational manner to insert or pull out the through hole. When the pin shaft is inserted into the through hole, the pin shaft cooperates with the pin hole of the lifting hook, which can form a locking and restraining effect on the lifting hook, thereby improving the storage stability of the lifting hook.

[0024] In addition, the pre - pressing mechanism is arranged on the lower side of the enclosing plate. The pre - pressing mechanism has a pressing part. An avoidance hole opposite to the pressing part is opened in the lower part of the enclosing plate. A pressure sensor is arranged on the side of the enclosing plate facing the accommodating cavity. The control board is electrically connected to the pressure sensor and the driver respectively. The control board is configured to: receive the pressure signal detected by the pressure sensor, and when the detected pressure is less than the set pressure, control the driver to drive the pin to insert or pull out. That is to say, the pre - pressing mechanism assists in supporting the lifting hook through the pressing part when the lifting hook has been placed in the box. During this process, most of the gravity of the lifting hook is transferred to the pre - pressing mechanism, reducing the contact force between the lifting hook and the pin. At the same time, the frictional resistance during the insertion and extraction movement of the pin is reduced, enabling the driver to drive the pin to complete the insertion or extraction action smoothly. After the pin is inserted, the pre - pressing mechanism is released, and the strong contact force between the pin and the lifting hook can be restored, thus ensuring the storage stability and a higher degree of automation of the insertion and extraction operations.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Such as Figures 1 to 6As shown in the figure, a storage box for a marine lifting hook according to an embodiment of the present invention includes a storage box body 1, a pin shaft 2, a pin shaft bracket 3, a driver 4, a preloading mechanism 5, and a control board 6. The storage box body 1 includes two side plates 11 and an enclosing plate 12. The two side plates 11 are arranged at intervals, and the enclosing plate 12 is fixedly connected between the two side plates 11. The two side plates 11 and the enclosing plate 12 form an accommodating cavity 10 with an upper opening; through holes 13 are formed in both side plates 11, and the two through holes 13 coaxially penetrate the accommodating cavity 10; the pin shaft bracket 3 is installed on the outside of the storage box body 1, the pin shaft bracket 3 is provided with a sliding groove 31, the sliding groove 31 communicates with the through hole 13, the sliding groove 31 is in guiding cooperation with the pin shaft 2, and the pin shaft 2 is inserted and matched with the two through holes 13.

[0038] The driver 4 is installed on the pin shaft bracket 3, and the driver 4 is in transmission connection with the pin shaft 2; the preloading mechanism 5 is arranged on the lower side of the enclosing plate 12, the preloading mechanism 5 has a pressing part 51, an avoidance hole 14 opposite to the pressing part 51 is formed in the lower part of the enclosing plate 12, and the pressing part 51 is used to assist in supporting the lifting hook 7 to reduce the insertion and extraction resistance of the pin shaft 2; a pressure sensor 15 is arranged on the side of the enclosing plate 12 facing the accommodating cavity 10, and the control board 6 is electrically connected to the pressure sensor 15 and the driver 4 respectively; the control board 6 is configured to: receive the pressure signal detected by the pressure sensor 15, and when the detected pressure is less than the set pressure, control the driver 4 to drive the pin shaft 2 to perform insertion or extraction actions.

[0039] The storage box for the marine lifting hook adopts the design form of the storage box body 1, the pin shaft 2, the pin shaft bracket 3, the driver 4, the preloading mechanism 5, and the control board 6. The storage box body 1 includes two side plates 11 arranged at intervals, and an enclosing plate 12 fixedly connected between the two side plates 11. The two side plates 11 and the enclosing plate 12 form an accommodating cavity 10 with an upper opening. The storage box body 1 provides an accommodating cavity 10 for the lifting hook 7 to be placed therein. The two side plates 11 and the enclosing plate 12 together play a reliable limiting role on the lifting hook 7, ensuring that the lifting hook 7 can be effectively prevented from shaking and displacing under the bumpy working conditions of the ship's navigation.

[0040] Among them, through holes 13 are formed in both side plates 11, the two through holes 13 coaxially penetrate the accommodating cavity 10, the pin shaft bracket 3 is installed on the outside of the storage box body 1, the pin shaft bracket 3 is provided with a sliding groove 31, the sliding groove 31 communicates with the through hole 13, and the sliding groove 31 and the two through holes 13 form a pin shaft channel extending along the same axis, ensuring the straight-line motion accuracy of the pin shaft 2 during the insertion and extraction process and avoiding skew jamming. The driver 4 is installed on the pin shaft bracket 3, the driver 4 is in transmission connection with the pin shaft 2, and the driver 4 drives the pin shaft 2 to translate along the pin shaft channel to insert into or extract from the through hole 13. When the pin shaft 2 is inserted into the through hole 13, the pin shaft 2 is in pin hole fit with the lifting hook 7, which can form a locking and restraining effect on the lifting hook 7, thereby improving the storage stability of the lifting hook 7.

[0041] In addition, the pre - pressing mechanism 5 is arranged on the lower side of the enclosure plate 12. The pre - pressing mechanism 5 has a pressing part 51. An avoidance hole 14 opposite to the pressing part 51 is formed in the lower part of the enclosure plate 12. A pressure sensor 15 is arranged on the side of the enclosure plate 12 facing the accommodating cavity 10. The control board 6 is electrically connected to the pressure sensor 15 and the driver 4 respectively. The control board 6 is configured to: receive the pressure signal detected by the pressure sensor 15, and when the detected pressure is less than the set pressure, control the driver 4 to drive the pin shaft 2 to insert or pull out. That is to say, when the lifting hook 7 has been placed in the box, the pre - pressing mechanism 5 supports the lifting hook 7 by the pressing part 51. During this process, most of the gravity of the lifting hook 7 is transferred to the pre - pressing mechanism 5, reducing the contact force between the lifting hook 7 and the pin shaft 2. At the same time, the frictional resistance during the insertion and extraction movement of the pin shaft 2 is reduced, enabling the driver 4 to drive the pin shaft 2 to complete the insertion or extraction action smoothly. After the pin shaft 2 is inserted, the pre - pressing mechanism 5 is released, and the strong contact force between the pin shaft 2 and the lifting hook 7 can be restored, thus ensuring the storage stability and a higher degree of automation of the insertion and extraction operation.

[0042] In this embodiment, as Figure 7 shown, the control board 6 is also provided with a start button 61 and a shutdown button 62. The control board 6 is further configured to:

[0043] After the lifting hook 7 enters the box, operate the start button 61 to power on the control board 6 and turn on the pressure sensor 15; after the pin shaft 2 is inserted in place, operate the shutdown button 62 to power off the control board 6; before the lifting hook 7 exits the box, operate the start button to power on the control board 6 and turn on the pressure sensor 15; after the pin shaft 2 is pulled out in place, operate the shutdown button 62 to power off the control board 6. The starting nodes of the control board 6 are: one, after the lifting hook 7 enters the box and the pin shaft 2 is not inserted; two, before the lifting hook 7 exits the box and the pin shaft 2 is not pulled out. Before the lifting hook 7 enters the box and after it exits the box, the control board 6 is in a power - off state. Even if the detected pressure of the pressure sensor 15 is less than the set pressure, the pin shaft 2 will not be driven to insert or pull out.

[0044] Specifically, the set pressure is any pressure value between 0 and 0.25t. That is to say, the pre - pressing mechanism 5 bears most of the gravity of the lifting hook 7, thus significantly reducing the contact force between the lifting hook 7 and the pin shaft 2.

[0045] As a further preferred solution, the pre - pressing mechanism 5 is a manual hydraulic jack. The pre - pressing mechanism 5 has an unloading state and a pressing device. In the unloading state, the pressing part 51 of the pre - pressing mechanism 5 is lower than or flush with the upper end face of the avoidance hole 14; in the pressing state, the pressing part 51 of the pre - pressing mechanism 5 is higher than the upper end face of the avoidance hole 14. By repeatedly lifting and pressing the handle 52 of the manual hydraulic jack, the pressing part 51 can be gradually raised to the required supporting position, and operating the pressure relief valve can lower the pressing part 51 to the unloading state.

[0046] Among them, the shape of the enclosing plate 12 is a funnel shape that is wider at the top and narrower at the bottom. The inner contour of the enclosing plate 12 close to the accommodating cavity 10 is in concave-convex fit with the lifting hook 7. The shape matching degree between the funnel-shaped enclosing plate 12 and the lifting hook 7 can play an effective centering and positioning role. Moreover, the through hole 13 is arranged in the middle of the side plate 11. There are two pressure sensors 15, and the two pressure sensors 15 are symmetrically arranged on both sides of the through hole 13. The detected pressure is the sum of the pressures detected by the two pressure sensors 15. With the design of the two pressure sensors 15 being symmetrically arranged left and right, the reliability of the pressure detection result is higher.

[0047] As a further preferred solution, cushion wood layers 16 are fixed on the inner walls of the two side plates 11 and the enclosing plate 12. Bolts 162 are connected between the cushion wood layer 16 and the side plate 11, and between the cushion wood layer 16 and the enclosing plate 12. The cushion wood layer 16 is provided with counterbores 161, and nuts 163 are accommodated and installed in the counterbores 161. The nuts 163 are in threaded fit with the bolts 162. The cushion wood layer 16 relieves the hard contact between the lifting hook 7 and the storage box body 1, and plays a role in shock absorption and force balance.

[0048] Specifically, the pin shaft bracket 3 includes two end plates 32 and two web plates 33. The two end plates 32 are arranged at intervals along the extension direction of the sliding groove 31. The plate surfaces of the two web plates 33 are arranged parallel to the extension direction of the sliding groove 31. One web plate 33 is fixedly connected to the upper parts of the two end plates 32 and is fixedly connected to the lower side of the sliding groove 31, and the other web plate 33 is fixedly connected to the lower parts of the two end plates 32 and is fixedly connected to the deck.

[0049] And, the pin shaft bracket 3 further includes an installation pipe 34. The installation pipe 34 is fixedly arranged between the two end plates 32 and is fixedly connected to the two web plates 33 respectively. The driver 4 is an electric hydraulic push rod. The driver 4 is inserted into the installation pipe 34. A push rod through hole 321 is provided on one end plate 32. A connecting rod 41 is connected between the rod body end of the driver 4 and the pin shaft 2. The structural design of the pin shaft bracket 3 is simple, which can ensure the position stability of the sliding groove 31. Combining with the installation pipe 34 realizes the reasonable installation purpose of the driver 4 and avoids the problem of easy structural interference.

[0050] In addition, upper flanges 111 are provided on the upper parts of the two side plates 11, and the two upper flanges 111 are arranged to gradually move away from each other from bottom to top. Two outer flanges 121 are provided on the upper part of the enclosing plate 12, and the two outer flanges 121 are arranged to gradually move away from each other from bottom to top. The upper flanges 111 of the two side plates 11 and the outer flanges 121 of the enclosing plate 12 form a guiding flared opening with an upward opening, which can allow the lifting hook 7 to smoothly and accurately enter the storage box body 1.

[0051] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
