Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting equipment technology, specifically a limit detection device for a dry quenching coke elevator. Background Technology
[0002] In the dry quenching production process of coking plants, the dry quenching elevator system is a crucial component and a key piece of equipment. The stable operation of the elevator system directly affects the safe and stable operation of the dry quenching process. During use, multiple limit switches need to be installed on the surface of the elevator frame to ensure stable operation. During the initial and final travel periods of the elevator's movement, significant swaying occurs due to inertia. If the swaying amplitude is large, it can easily cause the limit switches to mis-activate, resulting in the loss or interruption of limit signals due to the swaying, leading to abnormal alarms and other abnormal phenomena. A greater impact is the decreased sensitivity of the limit switches, causing abnormal signals. Therefore, to address these issues, a limit detection device for dry quenching elevators is proposed. Utility Model Content
[0003] The purpose of this invention is to provide a limit detection device for a dry quenching coke elevator to solve the problems mentioned in the background art.

[0006] The lifting frame is equipped with a lifting platform inside. Limit switches are fixedly connected to the lifting frame on the upper and lower sides of the lifting platform. A docking plate is fixedly connected to the outer side of the contact rod of the lower limit switch. A detection mechanism is provided below the docking plate. An indicator light is fixedly connected to the lifting frame on one side of the detection mechanism.
[0007] The detection mechanism includes a detection frame, a sliding plate, and a detection body. The sliding plate is slidably connected inside the detection frame, and the detection body is fixedly connected above the sliding plate. An indicator light is installed on one side of the detection body, and a connecting rod is fixedly connected to the top of the detection body.
[0008] As an optional solution of the limit detection device for a dry quenching coke elevator described in this utility model, the number of the connecting rods is two sets, and the heights of the connecting rods are set at different heights.

[0010] In the dry quenching production operation process of the coking plant, the dry quenching hoist system is an important link of the whole dry quenching and belongs to a class of key equipment. Whether the hoist system can work stably directly affects the safe and stable operation of the dry quenching. When the hoist is in use, a plurality of limit switches need to be installed on the surface of the lifting frame to ensure the stable use of the hoist.

Once the shaking amplitude is large, the limit switch is easily misstarted, the limit signal is lost due to shaking, and abnormal phenomena such as hoist abnormal alarm are caused.

In use, the power supply is turned on, the detection mechanism is installed below the limit switch below, and the detection mechanism is installed in a member independent of the lifting frame, so that vibration is avoided due to the influence of the limit switch. When the limit switch shakes in actual use, the abutting plate on one side of the limit switch contacts the two groups of communication rods.

At this time, the communication rod is back and forth conducted, the display lamp is flickering, the warning effect is more obvious, and the detection effect on the limit switch can be effectively achieved.
[0011] As an optional scheme of the limiting detection device for the dry quenching hoist, the detection body includes a fixed frame and a battery, the inside of the fixed frame is provided with the battery, one side of the battery is fixedly connected with a second connecting line, the other end of the second connecting line is fixedly connected with the communication rod, the other side of the battery is fixedly connected with a contact plate, the other side of the contact plate is provided with a rotating plate in rotating connection with the fixed frame, the outside of the rotating plate is fixedly connected with a first connecting line, the other end of the first connecting line is fixedly connected with the communication rod, and the bottom of the fixed frame is in sliding connection with the top plate.
[0012] As an optional scheme of the limiting detection device for the dry quenching hoist, the side surface of the fixed frame is fixedly connected with a second spring, and the other end of the second spring is fixedly connected with the rotating plate.
[0013] As an optional scheme of the limiting detection device for the dry quenching hoist, the outside of the second connecting line is provided with a display lamp.
[0014] When the lifting platform contacts the limit switch, the abutting plate outside the limit switch excessively extrudes the communication rod, at this time, the detection body moves downward, and the first spring is compressed, at this time, the top plate can push the rotating plate and the contact plate apart, at this time, the circuit is disconnected, and the display lamp does not continuously flicker, thereby avoiding false alarms.
