Description

Technical Field

[0001] The invention relates to the technical field of hoisting devices, and in particular to a hoisting device for a heavy-duty hatch cover structure. Background Art

[0002] A rocket is a jet propulsion device that ejects hot air backward at high speed and uses the reaction force generated to move forward. It carries its own fuel and oxidant and does not rely on oxygen in the air for combustion. It can fly both in the atmosphere and in outer space. As the rocket propellant is consumed during flight, its mass continues to decrease, and it is a variable mass flying body. Modern rockets can be used as a tool for fast long-distance transportation, such as as a vehicle for sounding, launching artificial satellites, manned spacecraft, space stations, and boosters for other aircraft. If it is used to deliver combat warheads (warheads), it constitutes a rocket weapon. Rockets are (as of 2009) the only vehicle that can enable objects to reach cosmic speed, overcome or get rid of the earth's gravity, and enter outer space, and the speed of the rocket is obtained by the operation of the rocket engine. And if you want to be able to launch a rocket at sea, you need to use a rocket launch ship. For a rocket launch ship, when the rocket's launch hatch is not in use, a hatch cover is needed to seal the hatch, so as to protect the launch hatch. When the rocket needs to be launched, in order to facilitate the launch of the rocket, a lifting device is needed to move the hatch cover to another location before the rocket is launched, so as to avoid the hatch cover from hindering the rocket launch operation.

[0003] However, the existing lifting device has a poor positioning effect. When the rocket launch ship is traveling on the sea (the rocket launch ship is easily affected by the waves and shakes during its travel on the sea), the lifting device may easily move relative to the rocket launch ship due to the shaking of the rocket launch ship. Therefore, when the lifting device shakes as a whole, it may easily affect the removal or placement of the hatch cover (mainly reflected in the docking of the hatch cover with the hatch). When placing the hatch cover, manpower is needed to accurately place the hatch cover. Therefore, not only the labor cost is increased, but also the shaking of the hatch cover in the suspended state may easily cause bumps to the surrounding staff, thereby reducing the safety of the staff to a certain extent, and further reducing the practicability of the lifting device to a certain extent.

DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] See also Figure 1-13A lifting device for a heavy-duty hatch cover structure provided by an embodiment of the present invention includes a track 10 and a car body 20 slidably arranged on the track 10, and also includes: a support frame 30, which is driven by a driving assembly 70 to enable the support frame 30 to rotate relative to the car body 20, a crossbeam frame 40 is fixedly installed on the top of the support frame 30, a transverse frame 50 is laterally slidably arranged on the crossbeam frame 40, and a clamp 60 for clamping the hatch cover is vertically slidably arranged on the transverse frame 50; a bottom plate 7018, which is driven by the driving assembly 70 so that the bottom plate 7018 can be vertically slidably arranged on the bottom surface of the car body 20, and a plurality of fixed suction cups 7019 are fixedly installed on the bottom plate 7018.

[0038] In the above technical solution, by utilizing the driving assembly 70, when the vehicle body 20 moves to the specified position along the track 10, it not only drives the support frame 30 to rotate so that the clamp 60 can rotate to the top of the hatch, but also drives the multiple fixed suction cups 7019 on the bottom plate 7018 to move downward, so that the multiple fixed suction cups 7019 can be quickly adsorbed on the hull deck, thereby achieving the effect of quickly positioning the position after movement, so that the vehicle body 20 can be in a relatively static state with respect to the hull deck, thereby minimizing the shaking of the hull, causing the vehicle body 20 to shake relative to the hull, thereby affecting the placement operation of the hatch cover.

[0039] Specifically, the driving assembly 70 includes a second motor 7001 fixedly mounted on the support frame 30, and a second circular gear 7002 is fixedly mounted on the output end of the second motor 7001; a first fixed frame 7003 is fixedly mounted on the support frame 30, and a second worm 7004 is rotatably arranged on the first fixed frame 7003, and a third circular gear 7005 meshing with the second circular gear 7002 is fixedly mounted on the second worm 7004, and a first connecting member is fixedly mounted on the bottom end of the second worm 7004. Disk 7006; a second fixing frame 7014 is also fixedly installed on the support frame 30, and a screw rod 7015 is rotatably installed on the second fixing frame 7014, and a first threaded cylinder 7017 is threadedly arranged on the screw rod 7015, and the bottom end of the first threaded cylinder 7017 is rotatably arranged on the top surface of the bottom plate 7018; a sliding rod 7020 is vertically slidably arranged on the top end of the first threaded cylinder 7017, and a second connecting disk 7021 matching the first connecting disk 7006 is fixedly installed on the top end of the sliding rod 7020.

[0040] Furthermore, a sleeve 7016 is sleeved on the circumferential surface of the screw 7015, a first sliding groove is opened on the circumferential surface of the sleeve 7016 in the circumferential direction, a second sliding groove is opened on the circumferential surface of the sleeve 7016 in the axial direction, the first sliding groove and the second sliding groove are connected, and the first threaded cylinder 7017 is slidably arranged in the first sliding groove and the second sliding groove.

[0041] In the above technical solution, by utilizing the second motor 7001 on the support frame 30, the second circular gear 7002 can be rotated under the action of the second motor 7001, and by relying on the mutual cooperation between the second circular gear 7002 and the third circular gear 7005 on the second worm 7004, the second worm 7004 on the support frame 30 can be rotated. Therefore, when the first connecting disk 7006 is connected to the second connecting disk 7021, it can drive the screw 7015 on the support frame 30 to rotate. By utilizing the sleeve 7016 on the screw 7015, since the first sliding groove and the second sliding groove are provided on the circumferential surface of the sleeve 7016, when the screw 7015 is rotating, the first threaded cylinder 7017 will be moved along the first sliding groove. The first threaded cylinder 7017 slides in the direction of the first slide groove, thereby enabling the clamp 60 on the support frame 30 to be rotated to the specified work position (i.e., the position directly above the hatch). After the first threaded cylinder 7017 moves along the direction of the first slide groove, the first threaded cylinder 7017 can slide in the direction of the second slide groove with the help of the mutual cooperation between the screw 7015 and the first threaded cylinder 7017, thereby enabling the first threaded cylinder 7017 to drive the multiple fixed suction cups 7019 on the bottom plate 7018 to slide downward, and then when the vehicle body 20 travels to the specified position along the track 10, the multiple fixed suction cups 7019 on the bottom plate 7018 can be adsorbed on the deck of the hull, thereby fixing the working position of the vehicle body 20.

[0042] Specifically, a fixed seat 7007 is fixedly installed on the support frame 30, and a rotating rod 7008 is rotatably arranged on the fixed seat 7007. A second worm gear 7009 matching with the second worm gear 7004 is fixedly installed on the circumferential surface of the rotating rod 7008, and a fourth circular gear 7010 is fixedly installed on one end of the rotating rod 7008; a second rack 7012 meshing with the fourth circular gear 7010 is slidably arranged on the fixed seat 7007, and an elastic member is arranged between the second rack 7012 and the fixed seat 7007, and the elastic member is a spring 7013; the second connecting disk 7021 and the second rack 7012 are connected by a connecting plate 7022.

[0043] In the above technical solution, by utilizing the mutual cooperation between the second worm 7004 and the second worm wheel 7009, when the second worm 7004 rotates, the second worm wheel 7009 can be rotated under the drive of the second worm 7004, so that the fourth circular gear 7010 on the rotating rod 7008 can be rotated, and by utilizing the mutual cooperation between the fourth circular gear 7010 and the second rack 7012, the second rack 7012 can move downward under the action of the fourth circular gear 7010, thereby driving The second connection plate 7021 can move downward, and the spring 7013 is in a stretched state at this time. Therefore, when the second rack 7012 moves downward to a certain position, the second connection plate 7021 can be temporarily separated from the second connection plate 7021, so that the screw rod 7015 on the support frame 30 no longer rotates (after the first connection plate 7006 and the second connection plate 7021 are completely separated, the multiple fixed suction cups 7019 on the bottom plate 7018 should have been completely adsorbed on the hull deck);

[0044] After the lifting device is used, the second motor 7001 is used again to enable the second rack 7012 to move upward under the action of the elastic force of the spring 7013, so that the fourth circular gear 7010 can re-engage with the second rack 7012, thereby achieving the effect of connecting the first connecting disk 7006 and the second connecting disk 7021 again. By using the first threaded cylinder 7017 to slide along the direction of the second slide groove and the first slide groove, the multiple fixed suction cups 7019 on the base plate 7018 can be lifted.

[0045] Furthermore, a guide rail 7011 is fixedly mounted on the fixing seat 7007 , and the second rack 7012 is slidably disposed on the guide rail 7011 .

[0046] By utilizing the guide rail 7011 , it is possible to restrict the sliding direction of the second rack 7012 .

[0048] In the above technical solution, after the first connecting disk 7006 is separated from the second connecting disk 7021, the steel cable 8004 wound on the roller 8003 can be stretched down from the roller 8003 by means of the continuous rotation of the second worm 7004 and the winding assembly 80, and the height of the clamped hatch cover can be adjusted by means of the weight of the clamp 60 itself.

[0049] Specifically, a first pulley 7023 is fixedly installed on the top of the second worm gear 7004, a connecting shaft 7024 is arranged between the support frame 30 and the crossbeam frame 40, a second pulley 7025 is fixedly installed on the circumference of the connecting shaft 7024, and the first pulley 7023 and the second pulley 7025 are connected by a first belt 7026; a first bevel gear 7027 is fixedly installed on the top of the connecting shaft 7024, and a second bevel gear 8002 meshing with the first bevel gear 7027 is fixedly installed on one end of the first rotating shaft.

[0050] In the above technical solution, by utilizing the first pulley 7023, the second pulley 7025 and the first belt 7026, the second worm 7004 can rotate while the connecting shaft 7024 on the support frame 30 can be rotated under the action of the second worm 7004, thereby achieving the effect of winding or stretching the steel cable 8004 with the help of the rotation of the second worm 7004.

[0051] Specifically, the winding assembly 80 also includes a second support plate 8005 fixedly mounted on the crossbeam frame 40, a second rotating shaft is rotatably arranged on the second support plate 8005, a third pulley 8006 is fixedly mounted on one end of the second rotating shaft, and a fourth pulley 8007 is fixedly mounted on the other end of the first rotating shaft, and the third pulley 8006 and the fourth pulley 8007 are connected via a second belt 8008 for transmission; a reciprocating screw 8009 is fixedly mounted on the circumferential surface of the second rotating shaft, a second threaded cylinder 8010 is threadedly arranged on the circumferential surface of the reciprocating screw 8009, two limit rods 8011 are fixedly mounted on the circumferential surface of the second threaded cylinder 8010, and the steel cable 8004 is slidably arranged between the two limit rods 8011.

[0052] In the above technical solution, by utilizing the reciprocating screw rod 8009, the second threaded cylinder 8010 can reciprocate along the axial direction of the reciprocating screw rod 8009, thereby assisting the steel cable 8004 with the help of two limit rods 8011 on the second threaded cylinder 8010, so that when the steel cable 8004 is wound onto the winding roller 8003, the wound steel cable 8004 can be arranged, thereby avoiding the occurrence of steel cable 8004 being entangled as much as possible, thereby facilitating the subsequent use of the steel cable 8004 on the winding roller 8003.

[0053] Furthermore, a guide rod 8012 is fixedly mounted on the second support plate 8005 , a sliding sleeve 8013 is axially slidably arranged on the guide rod 8012 , and a connecting rod is connected between the sliding sleeve 8013 and the first threaded sleeve.

[0054] In the above technical solution, by utilizing the guide rod 8012, the movement of the first thread can be limited.

[0055] Specifically, a cylinder 401 is fixedly installed on the crossbeam frame 40, and the output end of the cylinder 401 is fixedly installed on the transverse frame 50.

A plurality of guide wheels 506 are rotatably provided on the two first connecting frames 505 , and the guide wheels 506 are slidably provided on the guide rails 402 .

[0058] By utilizing the guide rail 402 and the guide wheel 506 , the moving direction of the clamp 60 can be limited.

[0059] Specifically, the clamp 60 includes a first fixed plate 6001 slidably arranged on the bottom surface of the transverse plate 501, a second connecting frame 6002 is fixedly installed on the top surface of the first fixed plate 6001, and the other end of the steel cable 8004 is fixedly connected to the top surface of the second connecting frame 6002; a plurality of scissor-type connecting members 6007 are arranged between the first fixed plate 6001 and the transverse plate 501; a second fixed plate 6003 is fixedly installed on the bottom surface of the first fixed plate 6001, and two sliding frames 6004 are arranged on the second fixed plate 6003 for colinear and reverse sliding, and sliding plates 6005 are slidably arranged at both ends of each sliding frame 6004, and electromagnetic suction cups 6006 are fixedly installed on the two sliding plates 6005; a driving mechanism for driving the two sliding frames 6004 to slide is arranged on the first fixed plate 6001 and the second fixed plate 6003.
