[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0021] See also Figure 1-4 The utility model provides the following technical solutions: a marine hydraulic lifting device for lifting heavy objects, comprising a support base 6, a first hydraulic component 3 is installed on one side of the support base 6 at an edge position, a second hydraulic component 7 is installed on the side of the support base 6 away from the first hydraulic component 3 at an edge position, a support platform 1 is installed on the top of the first hydraulic component 3 and the second hydraulic component 7, a plurality of pulleys 4 are arranged below the support base 6, a clamping lighting device 2 is arranged on the outside of the support platform 1, and the support base 6 and the plurality of pulleys 4 are connected by an auxiliary fixing device 5.

[0022] Specifically, the clamping lighting device 2 includes a mounting frame 21, a moving block 22, a vertical plate 23, a screw 24, a lighting assembly 25 and a rubber layer 26. The mounting frame 21 is provided on the outside of the support platform 1, and two vertical plates 23 are installed above the mounting frame 21. The inner side of the vertical plate 23 is installed with a screw 24 through a thread. The moving blocks 22 are installed on both sides adjacent to each other between the two screws 24 through bearings. The rubber layer 26 is installed on both sides adjacent to each other between the two moving blocks 22, and the lighting assembly 25 is installed above the moving block 22.

[0023] By adopting the above technical solution, the staff can clamp and fix the heavy object to a certain extent through the cooperation of the screw 24 and the moving block 22 when necessary, thereby reducing the possibility of the heavy object falling during the work process.

[0024] Specifically, the clamping lighting device 2 further includes screws 27 , and the supporting platform 1 and the mounting frame 21 are connected via two screws 27 .

[0025] By adopting the above technical solution, the staff can connect or separate the support platform 1 and the mounting frame 21 by using two screws 27 when needed, thereby facilitating the staff to install and remove the mounting frame 21 and other structures.

[0026] Specifically, the lighting assembly 25 includes a lighting lamp 251 and a transparent shell 252 . The transparent shell 252 is installed above the moving block 22 , and a plurality of lighting lamps 251 are installed inside the transparent shell 252 .

[0027] By adopting the above technical solution, the staff can provide certain auxiliary lighting through the cooperation of the lighting lamp 251 and the transparent shell 252 when needed, so as to better cope with the needs of some situations where there is insufficient light.

[0028] When this embodiment is used, when the ship needs to use the device to lift heavy objects, the staff installs the mounting frame 21 on the supporting platform 1 by clamping the two screws 27 in the lighting device 2, and then pushes the device to move the device to the working position through each pulley 4, and then places the heavy object between the two rubber layers 26 above the mounting frame 21, and rotates the two screws 24 respectively. The screws 24 are threadedly connected to the vertical plate 23, and the screws 24 are bearing-connected to the moving block 22. The outer bottom surface of the moving block 22 is tightly attached to the outer top surface of the mounting frame 21, so the two screws 24 respectively drive the two moving blocks 22 and the rubber layer 26 thereon to move, thereby clamping and fixing the heavy object. The staff can start the lighting lamps 251 in the two lighting assemblies 25 for auxiliary lighting, and the transparent shell 252 plays a role in protecting the lighting lamps 251. Then the staff manipulates the first hydraulic assembly 3 and the second hydraulic assembly 7 on the support base 6 to drive the support platform 1 and other structures to rise, thereby lifting the heavy object and performing work. Example 2

[0029] The difference between this embodiment and embodiment 1 is that the auxiliary fixing device 5 includes a fixed frame 51, a lifting plate 52, an electric telescopic rod 53, an inserting cone 54 and a suction cup 56; the support base 6 and the multiple pulleys 4 are connected through the fixed frame 51; multiple suction cups 56 are provided between the multiple pulleys 4; multiple inserting cones 54 are provided between the multiple pulleys 4 and on one side of the multiple suction cups 56; two lifting plates 52 are provided on the inner side of the fixed frame 51; the fixed frame 51 and the two lifting plates 52 are connected by two electric telescopic rods 53.

[0030] By adopting the above technical solution, the staff can fix the position of the device to a certain extent through the cooperation of structures such as the cone 54 or the suction cup 56 when necessary, thereby reducing the possibility of accidental movement of the device due to external vibration, external force collision or ground tilt.

[0031] Specifically, the auxiliary fixing device 5 further includes a threaded block 55 , and the suction cup 56 and the inserting cone 54 are both installed with a threaded block 55 on one side close to the lifting plate 52 .

[0032] By adopting the above technical solution, the staff can connect or separate the suction cup 56 and the inserting cone 54 from the two lifting plates 52 through the threaded block 55 when needed, thereby facilitating the staff to load and unload the suction cup 56 and the inserting cone 54.

[0033] When this embodiment is in use, when the device is working, if the ground is smooth, the staff can start the electric telescopic rod 53 above each suction cup 56 in the fixing frame 51 of the auxiliary fixing device 5, thereby driving each suction cup 56 to descend through the lifting plate 52 and each threaded block 55 until the suction cup 56 is adsorbed on the ground. If the ground is muddy, the staff can start the electric telescopic rod 53 above each cone 54 in the fixing frame 51, thereby driving each cone 54 to descend through the lifting plate 52 and each threaded block 55 until the cone 54 is inserted into the ground, thereby fixing the position of the device to a certain extent, thereby reducing the possibility of accidental movement of the device due to external vibration, external force collision or ground tilt.

[0034] In the present invention, the structures and principles of the support platform 1, the first hydraulic assembly 3 consisting of a gallows, an upper chute, a lower chute, a slider, a support block, a hydraulic cylinder and a locking mechanism, the pulley 4, the support base 6, and the second hydraulic assembly 7 consisting of a gallows, an upper chute, a lower chute, a slider, a support block, a hydraulic cylinder and a locking mechanism have been disclosed in a hydraulic lifting platform with a locking mechanism disclosed in Chinese patent application No. 202020181541.X. Its working principle is that when an object needs to be lifted, the object is placed on the upper end of the support platform, and then the control switch of the hydraulic cylinder is turned on. The piston rod of the hydraulic cylinder is extended, driving the slider in the lower slide groove to move to the left. Since the inner hinge and the outer hinge are hinged to form an "X"-shaped hinge, when the slider drives the outer hinge to move toward the inner hinge, the angles of the inner and outer hinges are also changing. At this time, the slider in the upper slide groove will also move in the same direction as the slider in the lower slide groove. When the angles between the upper and lower angles of the inner and outer hinges are reduced, since the lengths of the inner and outer hinges remain unchanged, the heights of the upper ends of the inner and outer hinges from the support base increase, thereby raising the height of the support platform and bringing the objects to the specified height. After the hydraulic platform rises to the specified height (end point), it needs to be in a static state, sometimes for unloading and sometimes for loading. At this time, in order to achieve the static state of the working platform at a certain height, the hydraulic cylinder is usually locked by the valve locking of the hydraulic cylinder itself (the hydraulic oil does not release and does not flow in reverse). However, if the object on the supporting platform is heavy, relying solely on the locking of the hydraulic cylinder will damage the hydraulic cylinder and pose a safety hazard. Therefore, after reaching the specified height, the inner and outer hinges are locked through the locking mechanism, and the fixing bolts are tightened in the screw holes. At this time, the rubber pads at the ends of the fixing bolts will be It will be tightly squeezed in the anti-slip groove on the surface of the telescopic plate, so that the telescopic plate is tightly and firmly fixed in the fixed sleeve. Since the length cannot be changed, the inner hinge and the outer hinge can be tightly locked and fixed, avoiding the locking by simply relying on the hydraulic cylinder; when the support platform needs to be lowered, the operation is the same as the above-mentioned raising of the object position. First, the piston rod of the hydraulic cylinder is controlled to contract, so that the sliders in the upper and lower slide grooves slide toward one side of the hydraulic cylinder, so that the inner hinge and the outer hinge also rotate around the middle connection point. Finally, the position of the support platform gradually decreases, driving the object at the upper end to drop to the specified height.

[0035] The working principle and use process of the present invention are as follows: when the ship needs to use the device to lift heavy objects, the staff installs the mounting frame 21 on the supporting platform 1 by clamping the two screws 27 in the lighting device 2, and then pushes the device to move the device to the working position through each pulley 4, and then places the heavy object between the two rubber layers 26 above the mounting frame 21, and rotates the two screws 24 respectively. The screws 24 are threadedly connected to the vertical plate 23, and the screws 24 are connected to the moving block 22 with bearings, and the outer bottom surface of the moving block 22 is tightly attached to the outer top surface of the mounting frame 21, so the two screws 24 respectively drive the two moving blocks 22 and the rubber layers 26 thereon to move, thereby clamping and fixing the heavy object. The staff can start the lighting lamps 251 in the two lighting assemblies 25 for auxiliary lighting, and the transparent shell 252 plays a role in protecting the lighting lamps 251. Then the staff operates the first hydraulic assembly 3 and the second hydraulic assembly 7 on the support base 6 to drive the support platform 1 and other structures to rise, and then lift the heavy objects to carry out the work; when the device is working, if the ground is a smooth surface, the staff can start the electric telescopic rod 53 above each suction cup 56 in the fixed frame 51 of the auxiliary fixing device 5, thereby driving each suction cup 56 to descend through the lifting plate 52 and each threaded block 55 until the suction cup 56 is adsorbed on the ground. If the ground is a muddy ground, the staff can start the electric telescopic rod 53 above each cone 54 in the fixed frame 51, thereby driving each cone 54 to descend through the lifting plate 52 and each threaded block 55 until the cone 54 is inserted into the ground, thereby fixing the position of the device to a certain extent, thereby reducing the possibility of accidental movement of the device due to external vibration, external force collision or ground tilt.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
