Problems solved by technology
Therefore, after a period of use, most of the sliders will wear out a deep ravine in the middle, causing the sliders to be scrapped and need to be replaced, and only one-fifth of the scrapped sliders are used, resulting in a great waste of sliders
On the other hand, four M6 countersunk head bolts are used to connect the slider and the collector bracket to the connecting plate. In addition, a high-strength spring is used to compress the slider and the grinding conductor. When replacing, tools are required to connect the slider to the grinding conductor. The conductance is pulled apart, and then the connecting plate and the slider are disassembled as a whole, and then reinstalled after the slider is replaced, which takes a long time and low operating efficiency

specific Embodiment approach
[0074] Through repeated research on the field use of the crane collector slider, the slider and the connecting plate are made into a disc shape, so that the slider can be rotated and adjusted with the center position as the origin. The specific implementation is as follows:
[0075] (1) Process a countersunk pin hole with a diameter of 12mm at the center of the slider and uniformly process small through holes with a diameter of 7mm at the concentric circle position at 30°.
[0076] (2) A hole of the same size as the slider is processed at the center of the connecting plate, and it can be matched with a small through hole with a diameter of 7mm on the slider, and four positioning pins with a diameter of 7mm and a height of 10mm are evenly welded and processed in the vertical direction of the slide line .
[0077] (3) The assembly connection between the slider and the connecting plate is connected by a 12mm countersunk head pin bolt through the middle connecting hole, and a pre...

The invention discloses a current collector sliding device. The current collector sliding device comprises a connecting plate and a sliding block, wherein the connecting plate and the sliding block are provided with a matched connecting structure, and the connecting structure can enable the sliding block to be connected to the connecting plate in different attitudes. In this scheme, the connectingattitude of the sliding block relative to the connecting plate can be adjusted through the connecting structure, so that the adjustment of the friction contact position of the sliding block and a friction electricity track is achieved, the friction contact surface of the sliding block and the friction electricity track is not limited to the same position any more, the friction contact position ofthe sliding block is greatly increased, and thus the utilization rate of the sliding block is effectively increased. The invention further discloses a bridge crane applying the current collector sliding device.
Description
technical field [0001] The invention relates to the technical field of power trolley lines, in particular to an overhead crane and a collector sliding device thereof. Background technique [0002] Overhead cranes are widely used in major heavy industry enterprises. It is responsible for the hoisting and transshipment of large objects. It is the transportation hub of enterprise logistics and an indispensable equipment in production activities. The power supply mode of each bridge crane basically adopts the power supply mode of the power trolley line. In order not to affect the power supply quality due to the dust accumulation on the ground conductor and ensure its good contact, a certain After the pressure, it transmits electric energy with the conduction friction of the mill installed parallel to the traveling track of the crane. [0003] In actual application, due to the narrow contact surface of the grinding conductor, the contact area between the slider and the grinding ...
