Description

The slip ring collector of the cantilever rotation mechanism of the circular crane manipulator

The utility model relates to a slip ring collector used for power supply of electrical equipment on a circular crane.

At present, the cantilever rotating mechanism of the circular crane manipulator imported in China uses flexible cables to directly connect the electrical equipment on the rotating mechanism with the electrical equipment on the fixed mechanism, and set a limit switch at the position of ±325° of the rotating mechanism to supply power. run. This power supply mode limits the rotation range of the manipulator cantilever, which is very inconvenient to operate. In addition, once the limit switch fails, it is easy to cause an accident of twisting and breaking the cable.

The purpose of this utility model is to provide a power supply device that can freely rotate the cantilever of the manipulator of the circular crane in the range of ±n×360° and work safely and reliably, so as to achieve the purpose of convenient and reliable operation and improve the working efficiency of the manipulator.

The purpose of this utility model is achieved in that the slip ring collector of the manipulator cantilever rotating mechanism of the ring crane is made up of two parts, a rotatable mechanism and a fixed mechanism. In the rotatable mechanism, there is a slip ring core connected with the cantilever rotary drive mechanism, and several insulating rings are sheathed on the slip ring core in turn, each insulating ring is covered with a conductive slip ring, and each insulating ring There are several through holes corresponding to each other on the side wall and the slip ring core barrel, the feeding flexible wire of the electrical equipment on the cantilever passes through the through holes of the slip ring core barrel and the insulating ring, and is connected with the conductive slip ring through a wire connector; In the fixed mechanism, there are several fixed insulating rods of collector brushes connected with the tower column of the circular crane, and several collector brushes corresponding to the conductive slip rings in the rotatable mechanism are installed on each fixed insulating rod of collector brushes Each collector brush holder is equipped with a collector brush, and the flexible wire in the tower column of the circular crane is connected to the collector brush holder through a wire connector; the collector brush in the fixed mechanism and the corresponding rotating mechanism The conductive slip ring is always in contact.

Since the power supply measure of the utility model is realized through the contact state between the collector brush in the fixing mechanism and the conductive slip ring in the corresponding rotating mechanism, it is not affected by the rotation of the manipulator cantilever, so that the reliable rotation range of the manipulator cantilever The expansion from ±325° to ±n×360° improves the operating performance and work efficiency of the manipulator of the circular crane, and also eliminates the potential accident of twisting and breaking the cable due to direct connection of the cable.

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1-6, the utility model is made up of two parts of rotatable mechanism and fixed mechanism. In the rotatable mechanism, there is a slip ring core barrel 1 connected with the cantilever rotation drive mechanism, and thirteen insulating rings 3 are sequentially sleeved on the slip ring core barrel 1 (this embodiment only takes thirteen as an example, in the figure Not all are drawn), and a conductive slip ring 2 is sleeved on each insulating ring 3. The inside of the insulating ring 3 is a stepped hole, and the outside is a two-step shaft-shaped sleeve, and the diameter of the lower outer step 15 is the same as that of the upper inner hole 14 . When the thirteen insulating rings 3 are sleeved on the annular core barrel 1, twelve annular insulating grooves are formed between the insulating rings 3, and a conductive slip ring 2 is arranged in each insulating groove. There are two through holes corresponding to each other on the side wall of each insulating ring 3 and the slip ring core barrel 1, and a wire protection insulating sleeve 9 is sleeved in the through holes, and is bonded and fixed with an adhesive. The feeding flexible wire 10 of the electrical equipment on the cantilever 13 passes through the wire protection insulating sleeve 9 and is connected to the conductive slip ring 2 through the wire connector 4 . In the fixing mechanism, there are four collector brush fixed insulating rods 5 connected with the tower column 12 of the ring crane, and each collector brush fixed insulating rod 5 is equipped with three collector brush holders 6 and conductive slides in the rotatable mechanism. The rings 2 are staggered and corresponding, so that the same conductive slip ring 2 has only one collector brush holder 6 corresponding to it. The collector brush holder 6 is a V-shaped structure, with a tension spring 16 on the inside and an elastic pressure piece 17 on the outside. Elastic pressure piece 17 is pressed on the collector brush 7 that is connected with its end. The flexible wire 10 in the tower column 12 of the circular crane passes through the wire protection insulating sleeve 11 at the connection between the tower column 12 and the collector, is fixed with a buckle, and is connected with the brush holder 6 through the wire connector 4 . There is a protective cover 8 connected to the tower column 12 of the circular crane around the fixed insulating rod 5 of the brush. Around the protective cover 8 and at a position corresponding to the brush holder 6, there is an installation and adjustment panel that can be opened. holes for easy brush replacement and pressure adjustment. The collector brush 7 in the fixed mechanism and the conductive slip ring 2 in the corresponding rotating mechanism are always in reliable contact, so that the flexible wire 10 in the tower column 12 and the flexible wire 10 of the electrical equipment on the cantilever are always kept in a safe and reliable conduction state.
