Description
Technical Field
The present invention relates to assemblies for container spreaders, and more particularly to a self-retracting reel for use on a container spreader.
Background
In normal operation of a container terminal or a cargo yard, a spreader is required to complete the gripping of a container or the transfer of cargo.
Generally, the lower part of a main machine is required to be connected with an upper frame, then the upper frame is connected with a lifting appliance, the main machine directly supplies power and signals to the upper frame, and a cable with the power and signals is provided for the lifting appliance on the upper frame.
The cable that the host computer provided power and signal for putting on shelf generally has tens meters, needs to be deposited by the container to lead to the cable to shake the range too big and fracture and collide with other wire ropes simultaneously at the host computer operation in-process, cause the risk. Generally, there are two types of cables for storing cables, i.e., a cable storage frame and a cable buffer.
However, some cranes have different connection modes, and are directly connected with a lifting appliance through a lifting hook and the like, and power supply and control signals of the lifting appliance are directly provided by cables coming off a host (namely a gantry crane), a gantry crane and the like instead. The cable is also required to be stored by the container, so that the cable is prevented from being broken due to overlarge shaking amplitude in the operation process of the main machine and colliding with other steel wire ropes at the same time, and risks are avoided. However, the cable storage frame and the cable buffer used on the original shelf cannot adapt to the working conditions on site sometimes. The cable storage frame has the limit of the lowest height and the lifting speed cannot be too fast, and when the cable buffer is used, the cable buffer is suitable for a host with the higher lifting speed, and meanwhile, parameters such as the diameter of the cable need to be verified, so that the use limit is more.

Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that variations and modifications can be made by persons skilled in the art without departing from the spirit of the invention. All falling within the scope of the present invention.
Referring to fig. 1 to 4, the present invention provides a self-retracting reel for a container spreader, including:
the winding drum body 1 is used for storing and winding and unwinding cables;
the power pack 2 is used for transmitting electric energy to the winding drum body 1, and the power supply is continuous and reliable; the power pack 2 uses slip ring wiring.
The spring group 3 is connected to the winding drum body 1, and when the winding drum body 1 is electrified and rotated to release the cable, the spring group 3 stores energy; when the reel body 1 needs to withdraw the cable, the spring group 3 releases energy as power to drive the reel body 1 to reversely withdraw the cable, so that electric energy is not consumed, the operation is flexible and reliable, and the cable abrasion is small.
The winding drum body 1 comprises a wire coil 11 for winding a cable and a main shaft 12 arranged at the circle center position of the wire coil 11.
The outer shell 31 is also provided with a scroll spring 33, the inner ring 331 of the scroll spring 33 is sleeved on the surface of the main shaft 12 in the outer shell 31, the scroll spring 33 transmits power in one direction, and a reversible structure is arranged, so that the scroll spring 33 cannot be broken due to reverse rotation.
The reversible structure comprises a key groove 34 arranged on the surface of the main shaft 12, a wedge-shaped flat key 35 connected with the inner ring of the volute spring 33 and corresponding to the key groove 34, and a small compression spring 36 arranged between the wedge-shaped flat key 35 and the key groove 34. When the main shaft 12 rotates counterclockwise as shown in fig. 4, the wedge-shaped flat key 35 presses the wedge-shaped flat key 35 into the key groove 34 under the action of the inner ring of the spiral spring 33 without rotating the inner ring of the spiral spring 33; otherwise, the rotation is driven, and the volute spring 33 works. However, the reversible structure is mainly used for preventing the spiral spring 33 from being broken under the condition that the cable is suddenly pulled to be broken after the cable is tightened.
One or two, in this embodiment two, volute springs 33 may be installed in parallel with the main shaft 12 in the axial direction, as required.
When the winding drum body 1 is paying off, the main shaft 12 is rotated through the wire disc 11, the inner ring 331 is driven to tighten the spiral spring 33, and kinetic energy is stored.
When the winding drum body 1 receives the cable, the kinetic energy released by the spiral spring 33 stored with the kinetic energy rotates the inner ring 331, drives the main shaft 12, and finally drives the wire coil 11 to wind the cable.
The self-recovery type winding drum is installed and debugged as follows:
1) when the cable winding and unwinding device is installed, the axis line of the winding drum body 1 is perpendicular to the motion track line of the cable winding and unwinding;
2) before the slip ring is connected, a megohmmeter is used for detecting whether two ends are communicated or not (see fig. 1, a cover plate with an electrical sign mark is disassembled to show a connecting terminal), and the connecting terminal is connected with a power supply channel with the number of wires and the number of cores. Meanwhile, the resistance between each path of channel and the resistance to the ground of the channel are required to be detected, and the insulation resistance value is more than 2 megaohms;
3) before the cable is coiled on the winding drum body 1, one end of the cable needs to penetrate into the U-shaped clamp and the waterproof joint on the wire coil 11, each core wire end of the cable is connected into the wiring terminal in the winding drum body 1, and the other end of the cable is connected into a power supply (or a mobile device). The other connecting terminal is connected with a cable, and the other end of the cable is connected with the mobile equipment (or a power supply);
4) adjustment of the winding force during installation: the cable drum for winding enough cable is closest to the mobile device, the drum body 1 (paying-off direction) is rotated to enable the spiral spring 33 to have certain pretightening force, the drum body 1 is stabilized, the cable is fixed by a clamp, and wiring is performed.
As shown in fig. 5, the operating state of the cable 4 after the installation of the winding drum body 1, wherein the two cable 4 states (a) and (b) are reasonable states, and the two cable 4 states (c) and (d) are avoided as much as possible, if the guide wheel 5 needs to be additionally installed, the guide wheel 5 must be flexibly rotated.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above described embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
