In an optional embodiment, the device for removing a steel platform in water in a narrow space comprises: the two winches 8 are respectively arranged on the support platform 3; the first pulleys are fixedly connected to the support platform 3; the first traction rope 7 penetrates through the first pulleys, two ends of the first traction rope 7 are connected to the two winches 8 respectively, and the sliding platform 2 is connected to the first traction rope 7. The hoist 8 is used as the drive, and first haulage rope 7 is the driving medium, and first pulley plays and makes the direction of drive power change, pulls sliding platform 2 through hoist 8 and slides on support platform 3.
The slidable working principle of the sliding platform 2 is as follows: the first traction rope 7 is a steel wire rope, the middle part of the first traction rope is welded and fixed on the sliding platform 2, the direction of the first traction rope 7 is arranged in the left-right direction in the drawing 1, two ends of the first traction rope 7 penetrate through two first pulleys fixed at the left end and the right end of the support platform 3 respectively and are connected to two winches 8, and the sliding of the sliding platform 2 on the support platform 3 is realized through the respective work of the two winches 8.
In an optional embodiment, the device for removing a steel platform in water in a narrow space further comprises: the counter weight water tank 9, counter weight water tank 9 can dismantle connect in the one end of keeping away from the surface of water on the supporting platform 3, counter weight water tank 9 is equipped with water filling port 11 and outlet 12. The counter weight water tank 9 plays the effect to the counter weight of whole device, when carrying out the construction operation, through water filling port 11 to counter weight water tank 9 water injection, increase weight, after the construction is accomplished, through the water in the 12 discharge counter weight water tanks 9 of outlet, convenient to detach and transportation. The counterweight water tank 9 is fixedly connected to the support platform 3 through bolts, and a base is welded to the bottom of the counterweight water tank 9 and is connected with the support platform 3 through bolts. The setting of base can play a buffering protection's effect to the water tank.
As will be understood by those skilled in the art, when the sliding platform 2 slides the lifting device 1 to the position on the water of the support platform 3, due to the self weight of the lifting device 1 and when lifting the steel platform member, the weight of the position on the water is heavy, and a part of the weight of the support platform 3 on the shore is relatively light, so that the whole device is unbalanced, which easily causes a part of the support platform 3 on the shore to tilt.

In this embodiment, as shown in fig. 2, the stopper 14 is disposed on the left side of the rack platform 3, and the pusher 5 is disposed on the right side of the rack platform. Since the sliding platform 2 is started on the left side without the hoisting steel platform member 20, it is light in weight and can be directly driven by the hoist 8. However, when the steel platform member 20 is hoisted on the right side of the sliding platform 2, the sliding platform 2 is subjected to the maximum static friction force when being started, and the working resistance of the winch 8 is large, so the pushing device 5 is arranged on the right side, the pushing device 5 can provide thrust to the sliding platform 2, the sliding platform 2 slides, and the winch 8 drives the sliding platform 2 to slide.
In an alternative embodiment, the supporting legs 6 are hydraulic rods or electric push rods. The supporting legs 6 are telescopic and can stretch into the water to play a role in supporting the support platform 3. It will be appreciated that the support legs 6 are provided in plurality to provide support for the stand platform 3.
In an alternative embodiment, as shown in fig. 3 and 4, the lifting device 1 comprises: the hoisting support is fixedly connected to the sliding platform 2; a hoisting manipulator 23 for grabbing the steel platform; the second pulleys are respectively and fixedly arranged on the hoisting bracket; the two driving devices 22 are fixedly arranged on the hoisting bracket; and the second traction rope 21 penetrates through the second pulley, two ends of the second traction rope 21 are respectively connected to the two driving devices 22, and the hoisting manipulator 23 is connected to the second traction rope 21.
The driving device provides driving force, the second traction rope 21 serves as a transmission piece, the hoisting manipulator 23 hoists the steel platform component 20, and the second pulley is installed on the hoisting support and used for changing the direction of the driving force. The sliding principle of the hoisting manipulator 23 on the hoisting support is consistent with that of a sliding platform.
The concrete operation method of the underwater steel platform dismantling device in the narrow space comprises the following steps: the dismantling device is erected firstly, then the underwater steel platform is dismantled into steel platform components 20, the steel platform components 20 are hoisted by the hoisting device 1, the steel platform components 20 are placed on the sliding platform 2, and after the steel platform components 20 are hoisted or when the steel platform components 20 on the sliding platform 2 reach the maximum placing amount, the steel platform components are transported to the shore by the sliding platform 2, so that the dismantling of the underwater steel platform is completed.
In an optional embodiment, the lifting device 1 is provided with a plurality of lifting devices on the sliding platform 2, and is used for quickly lifting the steel platform. The hoisting speed of the plurality of hoisting devices 1 is increased.
