Description

Technical Field

[0001] The utility model relates to a steel conductive sliding block of a crane, more specifically, it relates to a double-sided steel conductive sliding block device. Background Art

[0002] The traditional steel conductive slider device is a block with a length of 150mm, a width of 100mm, and a thickness of 25mm. Four 6mm holes are opened at the four corners. Bolts are passed from the bottom of the conductive slider upward through the copper plate and fixed with nuts on it. Since the front of the steel conductive slider is designed as an arc shape and the back is a quadrilateral corner, the front of the steel conductive slider is in an arc shape during the contact and conduction process between the steel busbar and the front of the steel conductive slider. The overhead crane will not be blocked by the unevenness of the steel busbar during movement. On the contrary, if the back is a quadrilateral corner, the overhead crane will be blocked during movement, causing damage to the steel busbar and breakage of the steel conductive slider. When the front of the steel slider is worn to a certain amount of loss, it needs to be replaced, otherwise there is a risk of device breakage. However, the replaced device is only worn by half or even less than half of the thickness, resulting in incomplete utilization of the device and increased device use costs. Utility Model Content

DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the embodiments, but does not constitute any limitation to the utility model. Any limited modifications made by anyone within the scope of the claims of the utility model are still within the scope of the claims of the utility model.

[0017] See also Figure 1-Figure 3The utility model discloses a double-sided steel conductive slider device, comprising an upper steel conductive slider 1 and a lower steel conductive slider 2. The upper steel conductive slider 1 and the lower steel conductive slider 2 are both provided with mounting grooves, and the upper steel conductive slider 1 covers the lower steel conductive slider 2, so that the two mounting grooves enclose an inner cavity 5. Through holes 3 are both provided at the end corners of the upper steel conductive slider 1 and the lower steel conductive slider 2. By screwing the fixing bolts inserted in the through holes 3 3 on the copper plate, the installation of the double-sided steel conductive slider device is realized, and the fixed connection between the upper steel conductive slider 1 and the lower steel conductive slider 2 is also realized.

[0018] A wear-resistant insulating frame 4 is provided in the inner cavity 5. In the present embodiment, the wear-resistant insulating frame 4 is composed of two wear-resistant vertical plates 42 and two wear-resistant horizontal plates 41, a stop channel 11 is provided between the two wear-resistant horizontal plates 41, and through holes 6 are provided at both ends of the two wear-resistant vertical plates 42. Furthermore, the wear-resistant insulating frame 4 is welded by steel plates, that is, the two wear-resistant vertical plates 42 and the two wear-resistant horizontal plates 41 are all steel plates. And a boron nitride insulating layer is provided on the periphery of the steel plate. Since boron nitride has good wear resistance and insulation, it can effectively cope with the friction of the steel busbar to protect the double-sided steel conductive slider device and avoid the problem that the double-sided steel conductive slider device is easily broken due to excessive friction. In addition, the boron nitride insulating layer is supported by the steel plate inside, which can improve the overall load-bearing capacity of the wear-resistant insulating frame 4 and ensure the overall rigidity of the double-sided steel conductive slider device.

[0019] In addition, a talc filler 8 is provided in the wear-resistant insulating frame 4, and the talc filler 8 is fixedly connected to the wear-resistant insulating frame 4 to form a connector that matches the inner cavity 5. When the connector is manufactured, the wear-resistant insulating frame 4 can be placed in a mold of the same size as the inner cavity 5, and then a mixture of talc powder and its adhesive is injected and cured to obtain an integral connector. When the steel busbar contacts and rubs with the connector, the talc powder produced by the talc filler 8 can reduce friction, thereby reducing the wear of the wear-resistant insulating frame 4.

[0020] A stop channel 11 is provided in the wear-resistant insulating frame 4, and the width of the stop channel 11 is smaller than the diameter of the steel busbar. With such a configuration, when the steel busbar contacts the wear-resistant insulating frame 4, the contact area between the steel busbar and the steel conductive slider is greatly reduced, thereby reducing its conductive performance; and due to the generation of talcum powder, the conductivity between the steel busbar and the steel conductive slider is further reduced, resulting in too low power supply for the equipment, making it difficult or even impossible for the equipment to operate, thereby intuitively reminding the staff that the double-sided steel conductive slider device is excessively worn.

[0021] In this embodiment, the upper steel conductive slider 1, the lower steel conductive slider 2 and the wear-resistant insulating frame 4 are connected by bolts. Specifically, the wear-resistant insulating frame 4 is provided with a plurality of through holes 1 6, and the upper steel conductive slider 1 is provided with a plurality of through holes 2 7 corresponding to the through holes 1 6. The through holes 2 7 are provided with countersunk holes for placing the heads of the bolts to prevent the bolts from protruding from the surface of the upper steel conductive slider 1. The lower steel conductive slider 2 is provided with a plurality of threaded holes 9 corresponding to the through holes 1 6. Bolts threadedly connected to the threaded holes 9 are inserted into the through holes 2 7 and the through holes 1 6.

[0022] The working principle of the utility model is: after the upper steel conductive slider 1, the lower steel conductive slider 2 and the wear-resistant insulating frame 4 are connected by bolts, the double-sided steel conductive slider device is installed on the copper plate. If the lower steel conductive slider 2 contacts the steel busbar, the lower steel conductive slider 2 is worn out first during the use of the equipment. When the lower steel conductive slider 2 is worn out and the steel busbar contacts the wear-resistant insulating frame 4, the contact area between the lower steel conductive slider 2 and the steel busbar is reduced and talcum powder exists between the two, which leads to a reduction in power supply, making it difficult or even impossible for the equipment to operate. At this time, the staff can remove the double-sided steel conductive slider device from the copper plate after powering off the equipment, and clean the talcum powder on the steel busbar, and then install the double-sided steel conductive slider device on the copper plate to make the upper steel conductive slider 1 contact the steel busbar.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
