Description

Technical Field

[0001] The present invention relates to the technical field of elevator equipment, and particularly relates to an elevator guide rail rust removal device. Background Art

[0002] When an elevator is equipped with sliding guide shoes, in order to reduce the friction of the guide shoes, an oil cup is installed on the guide shoes, and lubricating oil is stored in the oil cup to lubricate the guide rail at any time. While lubricating the guide rail, the working surface of the guide rail is also isolated from the air under the protection of the lubricating oil, playing a role in preventing the guide rail from rusting. For elevators equipped with roller guide shoes, the materials of the guide shoe rollers are nylon and rubber. If the guide rail is also rust-proofed with lubricating oil, the rollers will be soaked in the lubricating oil for a long time, and the lubricating oil will corrode the nylon and rubber of the rollers. Therefore, for the guide rail of the elevator equipped with roller guide shoes, the working surface of the guide rail is directly exposed to the air for a long time, and the working surface of the guide rail will rust, and the rust powder will stick to the guide rail, which may affect the running comfort of the elevator and the action performance of the safety clamp. At present, manual rust removal is usually used for rust removal of elevator guide rails, with low rust removal efficiency, affecting the normal operation of the elevator, and the safety of manual operation inside the elevator shaft is relatively low. Summary of the Invention

[0003] To achieve the above objectives, the present invention is realized through the following technical solutions: An elevator guide rail rust removal device specifically includes:

[0004] A clamping seat, which has a rectangular structure and a grinding chute opened on one side of the clamping seat. Both sides of the inner wall of the grinding chute are fixedly connected with fixed seats, and a grinding device is fixedly connected to the side of the fixed seat away from the inner wall of the grinding chute. A connecting bracket is fixedly connected to the top of the clamping seat;

[0005] A control seat, which has a square control seat body and a controller arranged on the top of the control seat. The controller is fixedly connected to the top of the control seat. A control device is fixedly connected to one side of the control seat. The side of the control seat away from the control device is fixedly connected to the inner wall of the grinding chute. There are two groups of control seats and they are symmetrically distributed inside the grinding chute;

[0006] The grinding device includes:

[0007] A grinding box, which has a box structure and a telescopic rod arranged inside the grinding box. One end of the telescopic rod is fixedly connected to the inner wall of the grinding box. One side of the grinding box penetrates and is fixedly connected with a support sleeve. A grinding head is slidably connected to the inner wall of the support sleeve. One end of the grinding head extends into the grinding box and is fixedly connected with a grinding push plate. The side of the grinding push plate away from the grinding head is fixedly connected to the telescopic rod;

[0008] The extrusion pad has an elastic columnar structure, and an alarm switch is arranged on one side of the extrusion pad. The alarm switch is fixedly connected to the extrusion pad. The alarm switch is electrically connected to an alarm. The side of the extrusion pad away from the alarm switch is fixed on the inner wall of the grinding box on the side away from the telescopic rod. An extrusion pad and an alarm switch are provided. As the grinding head wears, in order to press the grinding head against the side of the elevator guide rail, the telescopic rod needs to continuously increase the extension distance, and at the same time drive the grinding push plate to continuously move in the direction of the alarm switch. When the grinding head wears to a certain extent, the grinding push plate presses the alarm switch, and the alarm switch alarms through the alarm to remind the maintenance personnel to replace the grinding head, which facilitates timely replacement after the grinding wears to a certain extent and enables the grinding head to always maintain a good grinding effect.

[0009] This device is installed at the bottom of the elevator car through a connecting bracket, and the clamping seat is covered on the elevator guide rail through a grinding chute, so that the grinding devices inside the grinding chute are distributed on both sides of the elevator guide rail. When grinding is required, the telescopic rod drives the grinding push plate to move, and the grinding push plate drives the grinding head to move, so that the grinding head is pressed against both sides of the elevator guide rail. As the elevator car moves, it drives the grinding head to move on the elevator guide rail, and the elevator guide rail can be ground by the grinding head, eliminating the need for manual grinding, avoiding affecting the normal operation of the elevator, and eliminating the need for maintenance personnel to enter the elevator shaft, with good use safety.

[0010] Preferably, the side of the grinding box away from the support sleeve is fixedly connected to the inner wall of the grinding chute. Multiple support sleeves are provided and evenly distributed on the grinding box.

[0011] Preferably, guide chutes are provided on both sides of the inner wall of the grinding box. Guide sliders are fixedly connected to both ends of the grinding push plate. The side of the guide slider away from the grinding push plate extends into the guide chute and is slidably connected to the inner wall of the guide chute. The guide chute and the guide slider are provided. When the telescopic rod drives the grinding push plate to move, the guide slider and the guide chute can be used for limiting, avoiding tilting of the grinding push plate, enabling each grinding head on the grinding push plate to fully contact the elevator guide rail, and facilitating the full utilization of each grinding head on the grinding push plate.

[0012] Preferably, the grinding head includes a mounting seat. A threaded groove is formed on one side of the mounting seat. A grinding block is threadedly connected to the inner wall of the threaded groove. A cross groove is formed on one side of the grinding block. A cross slider is slidably connected to the inner wall of the cross groove. One end of the cross slider is fixedly connected to a compression spring. The end of the compression spring away from the cross slider is fixedly connected to the inner wall of the cross groove. The grinding head is provided. When one side of the grinding block inside the grinding head contacts the elevator guide rail, the grinding block wears, and at the same time the cross slider also wears. When the grinding block and the cross slider need to be replaced after being worn to a certain extent, insert a cross tool into the cross groove and squeeze the cross slider into the cross groove. After the cross tool is inserted and rotated to drive the grinding block to rotate, the grinding block can be taken out from the threaded groove, which is convenient for replacing the grinding block and the maintenance operation is convenient.

[0013] Preferably, the side of the mounting seat away from the threaded groove is fixedly connected to a grinding push plate. The mounting seat is arranged inside a support sleeve and is slidably connected to the inner wall of the support sleeve.

[0014] Preferably, the control device includes a control box. An elastic push rod is fixedly connected to one side of the inner wall of the control box. A control chute is formed on one side of the control box. A fixed frame is fixedly connected to the inner wall of the control chute. A friction plate is slidably connected to the inner wall of the fixed frame. One end of the friction plate is fixedly connected to a control spring. The end of the control spring away from the friction plate is fixedly connected to the inner wall of the control chute. An extrusion switch is fixedly connected to one side of the inner wall of the control chute close to the control spring. The control device is provided. When the surface of the elevator guide rail is smooth, the frictional force between the guide rail and the friction plate is small, and the force of the frictional force driving the friction plate to squeeze the control spring is small. When the surface of the elevator guide rail rusts, the frictional force between the guide rail and the friction plate increases, the degree of compression of the control spring increases, and the distance between the friction plate and the extrusion switch decreases. When the surface of the guide rail is corroded to a certain extent, that is, when the frictional force increases to a certain extent, at this time the friction plate compresses the control spring and touches the extrusion switch, and the extrusion switch can control the telescopic rod to extend through the controller. The telescopic rod can drive the grinding head to grind the surface of the elevator guide rail, which is convenient to automatically control whether to grind according to the corrosion degree of the surface of the elevator guide rail, without manual operation, easy to use, and there is no need for the grinding head to always contact the surface of the elevator guide rail, which is convenient to reduce the wear degree of the grinding head and extend the service life of the grinding head.

When the surface of the elevator guide rail is smooth, the frictional force between the guide rail and the friction plate is small, and the force driving the friction plate to squeeze the control spring is small. When the surface of the elevator guide rail is rusty, the frictional force between the guide rail and the friction plate increases, the degree of compression of the control spring increases, and the distance between the friction plate and the extrusion switch decreases. When the surface of the guide rail is corroded to a certain extent, that is, when the frictional force increases to a certain extent, at this time, the friction plate compresses the control spring and touches the extrusion switch.
