Technical Field
[0001] The utility model relates to the technical field of escalator step transmission guide rail systems, in particular to an escalator step guide rail with an oil guiding function. Background Art
[0002] As a fixed power transmission equipment for transporting passengers, escalators are widely used in crowded places such as airports, high-speed railway stations, subway stations and shopping malls, mainly for the purpose of transporting passengers. The steps, as the carrier for transporting passengers, are pulled by the step chain and circulate in the escalator path, and the main and auxiliary wheels of the steps run on the guide rails.
[0003] In order to ensure the normal operation of the equipment and the designed service life of the parts, lubrication of the step chain is essential. However, the lubricating oil of the escalator step chain will flow along the step guide to the escalator steps on the return side. The lubricating oil flowing to the steps will not only pollute the steps and affect the appearance of the escalator, but also pollute the environment. In addition, since there is oil on the step tread, the anti-slip performance of the step tread will be reduced, and there is a risk of passengers falling. Therefore, we need to propose an escalator step guide with oil guide function to solve the above problems. Utility Model Content
[0004] The utility model aims to provide an escalator step guide rail with an oil guiding function, thereby preventing lubricating oil from contaminating the steps, improving the appearance of the escalator, reducing pollution to the environment, and ensuring that the anti-skid performance of the step tread is not affected, so as to solve the problems raised in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an escalator step guide rail with an oil guiding function, comprising a guide rail body installed on both sides of the escalator, the guide rail body comprising a first mounting surface, a second mounting surface and a working surface, the working surface is provided with an oil guiding groove for guiding lubricating oil, the oil guiding groove divides the working surface into a main wheel working area and an auxiliary wheel working area, and one end of the main wheel working area away from the oil guiding groove is connected to the first mounting surface, and one end of the auxiliary wheel working area away from the oil guiding groove is connected to the second mounting surface.
[0006] Preferably, an arc-shaped protrusion is provided at the connection between the first mounting surface and the main wheel working area, and a folded edge is provided at the other end of the first mounting surface.
[0007] Preferably, the connection between the second mounting surface and the auxiliary wheel working area is set as an arc angle, the cross-section of the second mounting surface is set in an L shape, and there is a gap between the first mounting surface and the second mounting surface.
[0008] Preferably, the cross-section of the oil guide groove is arc-shaped, and the oil guide groove is located in the middle of the working surface.
[0009] Preferably, the cross-section of the main wheel working area is arranged in a straight line, and the main wheel working area and the auxiliary wheel working area are arranged flush.
[0010] Preferably, the cross-section of the main wheel working area is arranged in an inverted L-shape, and the lower end of the main wheel working area is flush with the auxiliary wheel working area.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The utility model mainly comprises a guide rail body consisting of a first mounting surface, a second mounting surface and a working surface, wherein the working surface comprises a main wheel working area and an auxiliary wheel working area, and an oil guide groove is arranged between the main wheel working area and the auxiliary wheel working area. When the step chain is filled with lubricating oil, the lubricating oil flows to the main wheel working area and then flows along the oil guide groove to the oil box at the lower part, but does not flow to the auxiliary wheel working area, thereby preventing the lubricating oil of the step chain from flowing along the side of the auxiliary wheel working area to the escalator steps on the return side and polluting the steps. This not only reduces environmental pollution, but also ensures that the anti-skid performance of the step tread is not affected, thereby improving the safety of passengers.

[0020] like Figure 3 As shown, during installation, the guide rail body 5 is installed at both ends of the escalator step 1, so that the step main wheel 3 is located in the main wheel working area 7, the step auxiliary wheel 2 is located in the auxiliary wheel working area 8, and the oil guide groove 6 is located between the step main wheel 3 and the step auxiliary wheel 2. An oil box is provided at the lower part of the escalator and at the end of the oil guide groove 6. When the lubricating oil is filled into the step chain 4, the lubricating oil flows to the main wheel working area 7 and then flows along the oil guide groove 6 to the lower oil box, and will not flow to the auxiliary wheel working area 8, so that the lubricating oil of the step chain 4 will not flow along the side of the auxiliary wheel working area 8 to the escalator step 1 on the return side and pollute the steps. This can not only reduce environmental pollution, but also ensure that the anti-slip performance of the step tread is not affected, thereby improving the safety of passengers.

[0023] The cross section of the oil guide groove 6 is arc-shaped and is located in the middle of the working surface, so that the lubricating oil dripping from the step chain 4 can be guided to the oil box at the bottom of the escalator for collection by using the oil guide groove 6 .
[0024] The cross section of the main wheel working area 7 is arranged in a straight line, and the main wheel working area 7 and the auxiliary wheel working area 8 are arranged flush, so that the bending resistance of the guide rail body 5 is improved, the guide rail has better rigidity and is not easy to deform, and is suitable for use in escalators with an inclination angle of 35°.
