Description

Technical Field

[0001] The utility model relates to the technical field of dry quenching coke elevators, in particular to a position limiting and anti-collision sensing device for dry quenching coke elevators. Background Art

[0002] In the coking industry, dry coke quenching (CDQ) units are increasingly becoming the mainstream red coke quenching unit on the market. The elevator is a crucial piece of hardware within the entire CDQ unit. The elevator is required to lift the coke drum containing red coke along the guide rails of the hoisting derrick to the CDQ furnace entrance and load the red coke into the CDQ furnace via a loading device. The hoisting derrick is generally about 38 meters above the ground, so many U-shaped limiters are installed on the hoisting derrick to control the hoist's lifting and lowering processes. The U-shaped limiters are 25mm wide. During actual production operations, the width of the guide rails of the hoisting derrick gradually deforms, causing the coke drum to sway left and right during ascent or descent. This can damage the limit sensing unit and the limit device. In severe cases, all limit devices on the entire derrick are damaged, damaging the equipment and causing a series of control system failures, resulting in economic losses.

[0003] To address these issues, a limit and anti-collision sensing device for CDQ elevators is urgently needed. This device can extend the service life of the U-shaped limiter and reduce the equipment's failure rate. This improves production efficiency, saves equipment maintenance costs for the company, and significantly improves the reliability and safety of the CDQ elevator, providing a safer and more efficient production operation. Summary of the Invention

DETAILED DESCRIPTION

[0020] In order to make the technical solution of the present invention easier to understand, the technical solution of the present invention is now clearly and completely described in conjunction with the accompanying drawings using specific embodiments.

[0021] Example 1:

[0022] like Figure 1-6 As shown, the embodiment of the present invention Figure 1-6 The utility model is a position limiting and anti-collision sensing device for a dry quenching coke hoist, comprising a hoisting tower frame 1 and a coke tank 2, wherein:

[0023] A plurality of limit sensor brackets 3 are provided on the side of the lifting tower derrick 1 close to the lifting route of the coke tank 2. The limit sensor brackets 3 are equipped with U-shaped electronic induction sensors 4. Limit sensing devices 5 are provided on both sides of the coke tank 2 frame.

[0024] The position limit sensing device 5 includes a position limit sensing block 501 , a position limit sensing portion of the position limit sensing block 501 is provided with a metal screen 502 , a rubber protective cover 503 is provided on the outer cover of the metal screen 502 , and a tin foil protective cover 504 is wrapped around the position limit sensing block 501 .

[0025] The limit sensor bracket 3 includes a pair of horizontal fixing brackets 301, one end of the pair of horizontal fixing brackets 301 is fixedly connected to the vertical fixing bracket 302, and the vertical fixing bracket 302 is fixedly installed on the inner side of the lifting tower derrick 1. A sliding groove 303 is provided in the pair of horizontal fixing brackets 301, and a spring fixing block 304 is fixedly provided on the side of the sliding groove 303 close to the vertical fixing bracket 302. One side of the spring fixing block 304 is connected to one end of the spring 305, and the other end of the spring 305 is connected to the slider 306. The slider 306 is fixedly connected to one end of the sensor connecting rod 307, and the other end of the sensor connecting rod 307 is fixedly connected to the sensor fixing bracket 308. The sensor fixing bracket 308 is equipped with a U-shaped electronic induction sensor 4.

[0026] An anti-collision rubber pad 309 is provided on one side of the spring fixing block 304 close to the spring 305 .

[0027] The lifting tower derrick 1 is provided with a plurality of motors, and the motors are electrically connected to the U-shaped electronic induction sensors 4 .

[0028] The metal screen 502 is provided with two layers of rubber protective covers 503 on the outside.

[0029] When the device is in use, after the coke drum 2 is installed in the lifting tower derrick 1, it is lifted. When the limit sensing devices 5 provided on both sides of the coke drum 2 pass through the limit sensor bracket 3, due to gravity, the coke drum 2 shakes left and right, causing the limit sensing devices 5 to collide with the U-shaped electronic induction sensor 4 installed on the limit sensor bracket 3;

[0030] When a collision occurs, the two layers of rubber protective cover 503 wrapped around the limit sensing block 501 and the tin foil protective cover 504 included on the entire outside of the limit sensing block 501 will protect the limit sensing block 501 and reduce the force of the collision. At this time, the collision force will drive the U-shaped electronic sensing sensor 4 to move to one side. At this time, the slider 306 connected to the sensor connecting rod 307 will compress the spring 305, allowing the U-shaped electronic sensing sensor 4 to move in the direction of the collision. At this time, the collision force will be eliminated, thereby achieving the effect of the protection device.

[0031] A sliding groove 303 is provided in the transverse fixing bracket 301 on the limit sensor bracket 3, which, together with the use of the spring 305, can achieve a certain buffering effect so that the device will not suffer sudden damage when encountering external forces.

[0032] The design of the spring fixing block 304 increases elasticity and can absorb a portion of the power when an accident occurs. This buffering mechanism reduces the impact force caused by the collision, thereby reducing damage to the entire system.

[0033] A bump rubber 309 with high friction coefficient and good elastic property is arranged near the spring fixing block 304, which can effectively reduce the impact force in the collision.

[0034] The outer part of the limiting sensing block 501 is protected by a metal screen 502 and a multi-layer rubber protective sleeve 503, which can enhance its durability. These materials can effectively resist the impact of external objects and avoid direct damage to the sensor in the event of an accident.

[0035] The tin foil protective sleeve 504 can reduce electromagnetic interference and static accumulation, ensuring the normal operation of the sensor. This design ensures that the sensor can still reliably detect the position in extreme working conditions and prevent misoperation.

[0036] It should be noted that the embodiments described herein are only some embodiments of the present application, not all implementation modes of the present application. The embodiments are only exemplary and their role is only to provide a more intuitive and clear way to understand the content of the present application, and not to limit the technical solutions of the present application. Without departing from the concept of the present application, all other embodiments that can be thought of by those skilled in the art without creative labor, and other simple replacements and various changes of the technical solutions of the present application, all belong to the protection scope of the present application.
