Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of elevator guide shoes, in particular to an elevator guide shoe with an oil cup. Background Art
[0002] The guide shoe includes a nylon block that can slide between the elevator guide rail and the car. The guide shoe consists of a guide shoe head, a guide shoe body, a guide shoe seat, etc. It can fix the car on the guide rail so that the car can only move up and down. There is also an oil cup on the upper part of the guide shoe to reduce the friction between the shoe lining and the guide rail. Each elevator car is equipped with four sets of guide shoes, which are installed on both sides of the upper beam and under the safety clamp seat at the bottom of the car. Four sets of counterweight guide shoes are installed at the bottom and upper part of the counterweight beam. The guide shoes fixed on the car can move back and forth along the fixed guide rails installed on the wall of the building shaft to prevent the car from deflecting or swinging during operation.
[0003] The oil cup is used to apply lubricating oil to the elevator guide rails, which can prevent rust and reduce wear on the elevator guide rails. The existing oil cup is usually an oil pot with an oil brush underneath. The cotton thread transfers the lubricating oil to the oil brush through the cotton rope, and then the oil brush is applied to the surface of the elevator guide rail. In the prior art, the oil cup of the elevator guide rail applies the lubricating oil to the surface of the elevator guide rail through the sliding friction between the cotton rope and the guide rail. The disadvantage of this is that the sliding friction wears the cotton rope quickly, and the cotton rope will be completely consumed over time, and eventually the surface of the elevator guide rail cannot be lubricated with oil.
[0004] Therefore, it is necessary to invent an elevator guide shoe with an oil cup to solve the above problems. Utility Model Content
[0005] In order to solve the deficiencies of the prior art, the purpose of the utility model is to provide an elevator guide shoe with an oil cup, which solves the problem that in actual use, the oil cup of the elevator guide rail applies lubricating oil to the surface of the elevator guide rail through the sliding friction between the cotton rope and the guide rail, and the sliding friction causes the cotton rope to wear quickly, and the cotton rope will be completely consumed over time, and ultimately the surface of the elevator guide rail cannot be oiled and lubricated.
[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:
[0007] An elevator guide shoe with an oil cup comprises an L-shaped guide shoe bracket with a plurality of reinforcing ribs, wherein the outer side wall of the guide shoe bracket is provided with sliding blocks for sliding guide rails on the opposite sides along the length direction, and the guide shoe bracket is provided with an oil cup body located between the reinforcing ribs at the top and bottom ends of the sliding block side walls, and the bottom end of the guide shoe bracket is provided with a lubrication roller that can slide along the guide rail, and the bottom of the oil cup body is provided with an oil guide cotton strip, and the bottom of the oil guide cotton strip is connected to a strip of oil guide cotton that fits the lubrication roller.
[0008] As a preferred solution of the utility model, an observation hole for observing the oil level is provided on the outer side wall of the oil cup body, a scale is provided on one side of the observation hole, and an oil cup cover is provided on the top of the oil cup body.
[0009] As a preferred solution of the utility model, the guide shoe bracket is located on one side of the bottom end of the oil cup body and is detachably mounted with an articulated bracket, the bottom end of the articulated bracket is hinged with a roller bracket that can be synchronously extruded inward, and the bottom end of the roller bracket is provided with a rotatable lubrication roller, and the length of the lubrication roller is less than the length of the strip oil guide cotton.
[0010] As a preferred solution of the utility model, a spring connection block for pushing the lubrication roller to be rollingly connected to the guide rail is provided at one end of the roller bracket.
[0011] As a preferred solution of the utility model, the axial direction of the lubrication roller is parallel to the width direction of the guide rail.
[0012] As a preferred solution of the utility model, the top end of the strip-shaped oil-conducting cotton is detachably connected to the inside of the hinged bracket.
[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:
[0014] In the utility model, the oil cup body is installed between the reinforcing ribs of the guide shoe bracket, so that the elevator guide shoe and the oil cup are integrated together, the structure is compact, and the installation time of the equipment is saved. The spring connecting block is arranged so that the lubricating roller with lubricating oil is fitted and rolled with the elevator guide rail, and the lubricating oil is applied to the elevator guide rail. The oil guide cotton strip and the strip oil guide cotton are arranged below the oil cup, so that the strip oil guide cotton can evenly apply the lubricating oil to the side wall of the lubricating roller. The lubricating roller, the guide rail and the strip oil guide cotton are in a rolling friction relationship, and the degree of wear is low, thereby increasing the service life of the strip oil guide cotton, while ensuring the lubrication effect on the guide rail surface, and solving the problem that the cotton rope wears too quickly and cannot be effectively lubricated.
