Description

Technical Field

[0001] The utility model relates to the technical field of port and navigation engineering construction, in particular to a hoisting structure for port and navigation engineering construction. Background Art

[0002] The capping block is one of the prefabricated components commonly used in port and navigation engineering construction. At the port and navigation engineering construction site, it is often necessary to use the port and navigation engineering construction lifting structure to lift it so as to transport it to the designated area.

[0003] After searching, it is found that in order to prevent the top block from rotating during the lifting process, lifting rings are usually set at the four corners of the top block, and two movable electric hoists connected with hooks are set at both ends of the lifting frame of the lifting structure used for port and shipping engineering construction. Since two electric hoists are used, the two electric hoists need to be maintained separately during maintenance. Since the electric hoists are at a high place, in order to facilitate maintenance, the two electric hoists need to be moved to one end of the lifting frame. Once the electric hoists cannot be moved, the staff needs to move to the two ends of the lifting frame one after another to maintain the two electric hoists separately, which is inconvenient.

[0006] As an improvement, the hanging bracket is provided with a first bolt threadedly connected to the mounting plate.

[0007] As an improvement, the longitudinal section of the driving rod is square, and a first bearing connected to the base is provided on the surface of the driving rod.

[0008] As an improvement, the longitudinal section of the plug-in block is square, and the surface of the bidirectional lead screw is provided with a second bearing connected to the base.

[0009] As an improvement, the first motor and the second motor are both electrically connected to a controller, and the first motor and the second motor are both provided with a second bolt threadedly connected to the base.

[0018] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0019] A hoisting structure for port and navigation engineering construction, comprising a hoisting frame 6 connected with an adjustment assembly, a mounting plate 7 being provided at the bottom end of the hoisting frame 6, a first bolt being threadedly connected to the mounting plate 7 being provided on the hoisting frame 6, the adjustment assembly comprising a first rope 5 connected to the mounting plate 7, a base 3, a driving rod 12 rotatably connected to the base 3, a bidirectional lead screw 10, a slider 4 being threadedly connected to the bidirectional lead screw 10 and slidably connected to the base 3, a winding wheel 11 for winding up the first rope 5 being provided on the surface of the driving rod 12, the longitudinal section of the driving rod 12 being square, and a first bearing being provided on the surface of the driving rod 12 connected to the base 3 to reduce friction during rotation;

[0020] One end of the base 3 is detachably connected to the first motor 8 and the second motor 9, and the first motor 8 and the second motor 9 are both electrically connected to the controller. The first motor 8 and the second motor 9 are both brake motors. The first motor 8 and the second motor 9 are both provided with a second bolt threadedly connected to the base 3. The first motor 8 is driven and connected to the first socket plugged into the driving rod 12, and the second motor 9 is driven and connected to the second socket. One end of the bidirectional lead screw 10 is provided with a socket block plugged into the second socket, and the longitudinal section of the socket block is square. The surface of the bidirectional lead screw 10 is provided with a second bearing connected to the base 3 to reduce friction during rotation. The bottom end of the slider 4 is provided with a second rope 2, and the bottom end of the second rope 2 is provided with a hook 1. The second rope 2 is located at both ends of the slider 4, and the slider 4 is located at both ends of the bidirectional lead screw 10. The bottom end of the base 3 is provided with a slide groove slidably connected to the slider 4 to facilitate guiding the slider 4.

[0021] Working principle: Figure 1 As shown, remove the first bolt, then move the mounting plate 7 downward to separate it from the hanging frame 6, then hang the hanging frame 6 on other equipment and fix it thereto, and make the bottom end of the hanging frame 6 below the bottom end of the other equipment, put the mounting plate 7 in position, then pass the first bolt through the hanging frame 6 to connect it with the mounting plate 7, when in use, drive the winding wheel 11 to retract and release the first rope 5 by controlling the rotation of the first motor 8 to move the base 3 to a suitable height, and drive the bidirectional lead screw 10 to rotate by the second motor 9 to control the spacing between the two sliders 4, so as to facilitate the hoisting of pressure top blocks of different lengths;

[0022] When maintenance is required, the winding wheel 11 releases part of the first rope 5 by controlling the rotation of the first motor 8, so that the base 3 moves down, making it convenient for the staff at a low place to reach the first motor 8 and the second motor 9. The two motors are installed on one side of the base 3. When maintaining the motor, it is only necessary to move to the side close to the motor, without running between the two sides, which is convenient for maintenance. When the first motor 8 and the second motor 9 need to be removed, first remove the second bolt, and then move the first motor 8 and the second motor 9 away from the base 3. At this time, the first socket will be disengaged from the drive rod 12, and the second socket will be disengaged from the socket block.

[0023] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
