[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.
[0027] like Figures 1 to 6 As shown, a lifting frame for underwater equipment installation is mounted on a frame 1. Slides 2 are symmetrically installed on the surface of the frame 1 along the height direction. The slides 2 are connected to the frame 1 via several connecting blocks 3 distributed along the height direction. A fixed rod 4, aligned with the direction of the slides 2, is installed between two slides 2. A slider 5 is fixedly connected to the fixed rod 4. The slider 5 guides the fixed rod 4 as it moves up and down along the slides 2. Sleeves 6, which cooperate with the two slides 2, are provided at both ends of the slider 5. The slides 2 pass through the corresponding sleeves 6 and are slidably connected to them. Thus, the slider 5 can move up and down along the slides 2, driving the fixed rod 4 to move up and down along the slides 2. A motor (not shown) is provided at the bottom of the slider 5 to drive the slider 5 to move up and down along the slides 2. It is understood that the motor falls within the scope of existing technology, and its structure will not be described in detail in this embodiment.
[0028] To improve the efficiency of the slider 5 sliding along the slide 2, lubricant is sprayed inside the sleeve 6 during use to reduce the friction between the sleeve 6 and the slide 2.
[0029] In actual use, the underwater equipment to be installed is fixed on the slider 5. The slider 5 moves up and down along the slide rail 2 so that the underwater equipment to be installed follows the slider 5 up and down along the slide rail 2, thereby transferring the underwater equipment to be installed to a designated height position for installation. During this process, the fixing rod 4 provides support. Therefore, the fixing rod 4 should have sufficient strength.
[0030] In practical use, the fixing rod can be divided into several sections, and each section can be fixedly connected by flanges. This allows for the selection of fixing rods of different lengths according to actual needs.
[0031] To ensure that the underwater equipment to be installed can be securely fixed on the slider 5, the slider 5 is provided with fixing holes 7 for connecting and fixing the underwater equipment. After the cable or wire rope is fixed to the underwater equipment to be installed, it passes through the fixing holes 7, so that the underwater equipment to be installed can be securely fixed on the slider 5.
[0032] The bottom end of the fixing rod 4 extends downward through the slider 5 and is fixedly connected to the fixing plate 8 by fasteners, which can be fixing screws. When the underwater equipment to be installed descends to the specified height along the slide 2 with the slider 5, the fixing rod 4 needs to be fixedly connected to the fixing plate 8 at the specified position by fasteners. Then, the underwater equipment to be installed is removed from the slider 5 and installed at the specified position. Generally, the fixing plate 8 is usually the deck of a ship or other flat plate at other positions on the ship, depending on the actual work requirements.
[0033] After the underwater equipment to be installed is completed, loosen the fasteners to separate the fixing rod 4 from the fixing plate 8, start the motor, and the slider 5 will drive the fixing rod 4 to rise along the slide 2 to complete the retrieval of the fixing rod 4 and the slider 5.
[0034] To facilitate the lifting and lowering of multiple sets of underwater equipment, multiple lifting frames can be installed on the end face of the frame 1 in this embodiment, which can improve the lifting efficiency of underwater equipment and the subsequent installation efficiency.
[0035] The working principle of this embodiment is as follows:
[0036] The underwater equipment to be installed is secured to the slider 5 with a cable or wire rope, which passes through the fixing hole 7 on the slider 5. The motor is started, and the slider 5, along with the fixing rod 4, descends along the slide rails 2 on both sides of the surface of the frame 1. When the underwater equipment on the slider 5 reaches the designated height, the motor is turned off, and the bottom end of the fixing rod 4 is fixedly connected to the fixing plate 8 with fasteners, so that the bottom of the underwater equipment is placed on the fixing plate 8. The operator then installs the underwater equipment. After installation, the fasteners are loosened to separate the fixing rod 4 from the fixing plate 8, the cable or wire rope is untied, and the motor is started again, so that the slider 5, along with the fixing rod 4, rises along the slide rails 2 on both sides of the surface of the frame 1, completing the retrieval operation of the fixing rod 4 and the slider 5.
[0037] A support frame 9 is installed at the bottom of the surface of the frame 1. The bottom of the slide 2 passes through the support frame 9 and is fixed on the support frame 9. The support frame 9 limits the height of the slider 5 as it descends along the slide 2. When the slider 5 descends to the position of the support frame 9 along the slide 2, it stops descending. At this time, the bottom of the fixing rod 4 can contact the fixing plate 8 as the slider 5 descends. At this time, the fixing rod 4 and the fixing plate 8 are fixedly connected by fasteners.
[0038] The upper end face of the support frame 9 is provided with limit rings 10 at both ends. The bottom of the slide 2 can pass through the limit rings 10 and be fixedly connected to the support frame 9. When the slider 5 descends along the slide 2 to the position of the limit ring 10, it stops descending. Furthermore, the underwater equipment to be installed on the slider 5 has a certain weight. It is necessary to avoid the pressure on the support frame 9 caused by the direct contact between the slider 5 and the support frame 9, which may cause damage to the support frame 9. Therefore, the limit rings 10 can also provide a buffer for the contact between the slider 5 and the support frame 9.
[0039] A support plate 11 is installed circumferentially on the outer wall of the fixed rod 4. When the slider 5 descends along the slide 2 to the position of the limit ring 10, the support plate 11 can jointly bear the pressure of the underwater equipment to be installed on the slider 5. Therefore, it is necessary to ensure that when the slider 5 descends to the position of the support frame 9, the top of the support plate 11 on the outer wall of the fixed rod 4 is flush with the top of the limit ring 10.
[0040] When the underwater equipment to be installed is lowered to the designated installation position along the slide 2 with the slider 5, the bottom end of the fixing rod 4 is fixed to the fixing plate 8 by fasteners. In order to ensure that the fixing rod 4 does not shake, the fixing rod 4 needs to be fixed as a whole. Therefore, the top end of the fixing rod 4 is fixedly connected to the outside through the telescopic component.
[0041] Specifically, the telescopic assembly includes a clamp 12, a connecting rod 13, and a telescopic sleeve 14. The clamp 12 is fitted onto the outer wall of the fixed rod 4 by fixing screws. The clamp 12 can be fitted onto the outer wall of the fixed rod 4 according to the actual situation. The connecting rod 13 is integrally set with the clamp 12 and is set perpendicular to the fixed rod 4. One end of the connecting rod 13 is inserted into the telescopic sleeve 14, and the connecting rod 13 and the telescopic sleeve 14 are slidably engaged and relatively locked by a fastener. The relative position of the connecting rod 13 and the telescopic sleeve 14 also needs to be selected according to the actual situation of the fixed rod 4 and the external fixed position. The telescopic sleeve 14 has fixing grooves 15 at both ends. After the connecting rod 13 and the telescopic sleeve 14 are slidably engaged and relatively locked, the telescopic sleeve 14 is fixed to the external fixed position. At this time, the fixing screws or other fasteners pass through the fixing grooves 15 to fix the telescopic sleeve 14 to the outside, thus completing the overall fixing of the fixed rod 4.
[0042] To facilitate adjustment of the insertion depth of the connecting rod 13 into the telescopic sleeve 14, the connecting rod 13 and the telescopic sleeve 14 are installed and fixed by means of sliding engagement and relative locking of the fastener. Specifically, the connecting rod 13 is provided with several connecting holes 16, and the telescopic sleeve 14 is provided with several telescopic grooves 17. The telescopic grooves 17 cooperate with the connecting holes 16, and the fastener passes through the telescopic grooves 17 and the connecting holes 16 so that the connecting rod 13 and the telescopic sleeve 14 slide engagement and relative locking.
[0043] The top of the fixed rod 4 is fixedly installed with a lifting hole 18. When the underwater equipment needs to be replaced or repaired, the underwater equipment is fixed on the slider 5, the hook of the crane is hooked onto the lifting hole 18, and then the crane lifts the fixed rod 4 so that the slider 5 is lifted out together with the fixed rod 4, thereby completing the removal of the underwater equipment and replacing or repairing it.
[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
