Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of busbars, and in particular relates to a steel-based composite side-sliding busbar temperature compensation device. Background Art
[0002] As we all know, busbars are a group of power transmission devices that supply power to mobile devices. Steel-based composite busbars are made of copper-steel composite, consisting of dovetail copper rods and "I" steel. Busbars mainly include guide rails and current collectors. The guide rail material is usually a metal with good conductivity, such as copper and aluminum. The slider is a component in the current collector that slides on the side of the guide rail to conduct the electrical energy on the guide rail to the hub. Due to the principle of thermal expansion and contraction of metals, temperature compensation devices are widely used in busbars. The temperature compensation device of the busbar is a device used to solve the problem of expansion and contraction changes caused by the busbar under different temperature environments.
[0003] At present, the traditional busbar temperature compensation device is composed of two overlapping guide rails, one end of which is bent downward and overlapped with the other guide rail, and then fixed with bolts to ensure that the two guide rails are arranged along the same central axis.
[0004] However, it was found during use that the busbar temperature compensation device of the above structure still has the following defects:
[0005] After long-term operation, the long-term friction between the slider surface of the collector and the guide rail causes the slider surface to wear out and become concave. The unworn area of the slider hits the overlapping part of the temperature compensation device during sliding, which can cause damage to the slider and guide rail, and even cause production accidents, causing significant losses to factories and enterprises. Utility Model Content

[0009] Preferably, the minimum length of the long telescopic hole is not less than the maximum length change caused by the thermal expansion and contraction of the guide rail, so as to ensure that the temperature compensation device can move to the maximum distance during the thermal expansion and contraction of the guide rail.
[0010] Preferably, at least two bolts are fixed in the long telescopic hole, and the straight line direction determined by the two bolts is consistent with the central axis of the guide rail, which is used to limit the busbar to perform linear movement during thermal expansion and contraction.
[0011] Preferably, the thickness of the contact portion of the temperature compensation plate with the rail head is smaller than the thickness of other portions of the temperature compensation plate, so that the temperature compensation plate and the rail head are more tightly connected, further avoiding collision between the worn slider and the temperature compensation plate.
[0012] Preferably, the end face of the guide rail is I-shaped, and the guide rail includes a rail head, a rail waist and a rail bottom. The I-shaped guide rail can ensure the wear resistance and durability of the guide rail.

[0014] Preferably, the temperature compensation plate is fixedly connected to the rail waist through bolts and fixing holes, and the temperature compensation plate is symmetrically fixed to the rail waist to ensure the stability of the temperature compensation device.

[0017] Preferably, two bolts are fixed in the long telescopic hole, and the central axes of the two bolts and the three fixing holes are in a coplanar relationship.
[0018] Compared with the prior art, the beneficial effects of the utility model are:
[0019] The utility model realizes the phenomenon that the worn collector slider hits the temperature compensation device and causes the slider or guide rail to be damaged during the use of the slider by setting a steel-based composite side-sliding busbar temperature compensation device. 2N (N is a natural number greater than 0) temperature compensation plates and a plurality of fixing holes ensure the stability of the temperature compensation device; two arc chamfers are set on the side of the temperature compensation plate close to the slider to avoid the product being too sharp and affecting the installation and later maintenance of the operator; the distance from the arc chamfer to the side of the guide rail contacting the slider is greater than the thickness of the slider, ensuring that even if the slider is worn, the slider will not hit the temperature compensation device during the sliding process, avoiding the problem of damage to the slider or guide rail caused by the collision; the minimum length of the long telescopic hole is not less than the maximum length change caused by the thermal expansion and contraction of the guide rail, so that the temperature compensation device can have the maximum movable distance and provide the strongest temperature compensation capability; at least two bolts are fixed in the long telescopic hole, and the straight line direction determined by the two bolts is consistent with the central axis of the guide rail. According to the principle of two points determining a straight line, the movement direction of the temperature compensation device can be limited to be consistent with the direction of the guide rail, ensuring the linear telescopicity of the guide rail.

[0041] During the operation of the busbar, the slider 9 slides on the outer surface of the rail head 6 to transmit electricity from the guide rail 5 to the mobile power-consuming equipment. After the slider 9 slides for a long time, the surface of the slider 9 is worn due to the friction with the guide rail 5. During the sliding process of the slider 9 after wear, the distance between the arc chamfer 4 of the temperature compensation plate 1 and the guide rail 5 on one side of the slider 9 is greater than the thickness of the slider 9, and the thickness of the contact part of the temperature compensation plate 1 with the rail head 6 is less than the thickness of other parts. The arc fits with the rail head 6, so that the temperature compensation plate 1 and the rail head 6 are more tightly connected, which can ensure that the slider 9 smoothly transitions to the temperature compensation device. , and will not collide with the temperature compensation device, thereby avoiding power supply accidents; when the guide rail 5 expands and contracts, since the minimum length of the long telescopic hole 3 is not less than the maximum length change caused by the thermal expansion and contraction of the guide rail, the temperature compensation device can compensate for the length of the guide rail 5 under the maximum length difference caused by the thermal expansion and contraction of the guide rail 5; at least two bolts are fixed in the long telescopic hole 3, and the straight line direction determined by the two bolts is consistent with the central axis of the guide rail 5, which ensures that the busbar moves in a straight line during the thermal expansion and contraction process, so that the slider 9 can slide smoothly on the guide rail 5; the end face of the guide rail 5 is I-shaped, which increases the smoothness and wear resistance of the guide rail 5.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
