Description

Technical Field

[0001] The invention belongs to the technical field of coke oven coke pushing equipment, and in particular relates to a vibration reduction device and method for a coke pushing vehicle. Background Art

[0002] Coke is a kind of raw material that is widely used in industrial production. It is mainly used in metallurgy, electric power and other industrial sectors. It is an important raw material in metallurgical steelmaking and iron manufacturing. It is an important reducing agent in aluminum electrolysis production. It is used as a catalyst or reducing agent in certain chemical reactions. It can also be used as a raw material for carbon black. However, the main machine in the coke production process, the coke pusher, will have very large vibrations. This vibration will not only affect the working condition and life of the equipment, but also easily cause production accidents, causing the production process to be forced to stop. Therefore, an in-depth and systematic study of the causes of vibrations generated in the coke pushing process is of great significance to the production activities of today's coking industry.

[0003] The Chinese patent application number CN203794831U discloses an anti-vibration coke pushing device for a coke pushing machine suitable for a 6-meter coke oven, including a main transmission gear, a coke pushing rod, a front roller, and a rear roller; the coke pushing rod is supported by a pair of front rollers and a plurality of rear rollers, and the main transmission gear is located on the upper part of the coke pushing rod. The coke pushing rod includes a coke pushing head, a coke pushing rod body, a sliding shoe, and a stopper. The coke pushing head is located at the front end of the coke pushing rod body, the sliding shoe is located at the front position below the coke pushing rod body, and the two ends of the rack on the upper part of the coke pushing rod body are respectively equipped with stops. The sliding shoe adopts a hexagonal eccentric sleeve. The sliding shoe of the coke pushing rod of the patent can swing in the front and rear directions and in the left and right directions to adapt to the uneven condition of the bottom of the carbonization chamber and avoid excessive vibration of the coke pushing rod in all directions.

[0004] However, during the implementation of the above patent, when the sliding shoe contacts the bottom surface of the coke oven, there is a large collision, causing the coke pushing device to generate a large vibration. Summary of the invention

[0005] In view of the above problems, the present invention provides a vibration reduction device and method for a coke pushing vehicle.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A coke pushing vehicle vibration reduction device comprises an articulated seat and a mounting seat installed on a coke pushing rod, two mounting plates are fixed on the mounting seat, a No. 1 rotating shaft is rotatably arranged between the two mounting plates, a No. 1 encoder is installed on the No. 1 rotating shaft, the rear end of the No. 1 rotating shaft passes through the mounting plate and is connected with the output shaft of the No. 1 motor, the No. 1 motor is fixed to an adjacent mounting plate, the front end of the No. 1 rotating shaft passes through the mounting plate and is fixedly connected with an active bevel gear, the active bevel gear is meshingly connected with a driven bevel gear, the driven bevel gear is fixedly installed on a No. 2 rotating shaft, the No. 2 rotating shaft is rotatably installed on a fixed plate, the fixed plate is fixedly connected to an adjacent mounting plate, a sleeve is threadedly connected to the lower part of the No. 2 rotating shaft, a sliding shoe is installed at the lower end of the sleeve, and the sliding shoe Used to contact with the furnace, thereby reducing the vibration during the coke pushing process, a slider is fixedly connected to the sleeve, the slider is slidably set on a guide rail, the guide rail is fixedly installed on an adjacent mounting plate, a baffle is hinged at the rear of the mounting seat, a wire rope is connected to the lower end of the baffle, the other end of the wire rope is wound around a rolling wheel, the rolling wheel is rotatably connected to the hinge seat through rotating shafts fixed at both ends thereof, one of the rotating shafts is connected to the output shaft of the No. 2 motor, the No. 2 motor is fixedly installed on the hinge seat, the other rotating shaft extends out of the hinge seat and is equipped with a No. 2 encoder, a capacitive sensor is arranged on the lower side of the furnace entrance, the No. 1 motor, the No. 2 motor, the No. 1 encoder, the No. 2 encoder and the capacitive sensor are all electrically connected to the control console.

[0008] A coke pushing car vibration reduction method includes four stages:

[0009] In the first stage, the coke pusher driver starts the coke pusher, the coke pusher extends toward the furnace, and the vibration reduction device moves normally with the coke pusher. In this stage, the coke pusher has no vibration, the vibration reduction device does not move, and the steel cable is relaxed.

[0010] In the second stage, the vibration reduction device moves horizontally to the front of the furnace along with the coke pushing rod, and the baffle contacts the capacitive sensor at the upper end of the rear side of the furnace. After the capacitive sensor detects the signal, it transmits the signal to the control console. The control console controls the No. 1 motor and the No. 2 motor to rotate forward. The forward rotation of the No. 1 motor drives the No. 1 rotating shaft to rotate forward. The active bevel gear on the No. 1 rotating shaft drives the driven bevel gear to rotate, and then drives the No. 2 rotating shaft to rotate. Since the No. 2 rotating shaft is threadedly connected to the sleeve, and the sleeve is restricted by the slider to only move up and down, the sleeve drives the sliding shoe to descend when the No. 2 rotating shaft rotates, and the No. 2 motor rotates forward to drive the roller pair The steel wire rope is wound to realize the lifting of the baffle. In this process, the number of rotations of the No. 1 motor and the No. 2 motor is counted respectively through the No. 1 encoder and the No. 2 encoder. When the number of rotations reaches the set value, the signal value control console is transmitted, and the No. 1 motor and the No. 2 motor are controlled to stop forward rotation through the control console. When the No. 1 motor stops forward rotation, the sliding shoe just contacts the upper surface of the furnace. The sliding shoe is accurately lowered through the cooperation of the control console and the No. 1 encoder, avoiding the violent collision and impact between the sliding shoe and the furnace. When the No. 2 motor stops forward rotation, the baffle is lifted to the specified height.

[0011] In the third stage, the coke pushing car drives the coke pushing rod to continue moving forward and starts the coke pushing work. After the coke pushing is completed, the vibration reduction device extends out of the furnace together with the coke pushing rod.

[0012] In the fourth stage, the coke pushing car driver retracts the coke pushing rod and controls the No. 1 motor to reverse through the control console to lift the sliding shoe. When the sliding shoe is lifted to the initial height, the No. 1 motor is automatically stopped through the feedback of the No. 1 encoder. When the vibration reduction device withdraws from the entrance side of the furnace together with the coke pushing rod, the coke pushing car driver controls the No. 2 motor to rotate in the opposite direction through the control console to lower the baffle. When the baffle is lowered to the specified height, the No. 2 motor is automatically stopped through the feedback of the No. 2 encoder, completing the lifting of the sliding shoe and the lowering of the baffle.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The present invention innovatively solves the problem of the uncertain lowering time of the coke pushing device's sliding shoe, by approaching the furnace with a baffle to trigger the capacitive sensor to accurately send out a control signal, so that the sliding shoe can be accurately lowered in advance, and the cooperation of the No. 1 encoder and the No. 1 motor can realize the accurate control of the sliding shoe lowering height, so as to avoid the sliding shoe and the furnace floor suddenly contacting each time the coke pushing head enters the furnace, causing violent collision and impact, thereby causing the device to vibrate strongly, thereby realizing the smooth operation of the coke pushing production operation, reducing the vibration and wear of the coke pushing machine, and improving the stability of the coke pushing operation when the coke pushing machine enters the furnace, so that the entire coke pushing process is stable and efficient. At the same time, the lifting structure of the sliding shoe in the present invention is simple, and it only needs to set the lower height in advance, so that it can be applied to various types of furnace heights with an uncertain range, and no large amount of maintenance work is required. It is easy to operate and maintain, and the cost of replacement and installation on the existing coke pushing equipment is low, which has good economic benefits.

[0015] The invention has a wide application range, high economic benefits, low modification difficulty for existing old equipment, low modification cost, high reliability, and is not easily affected by environmental factors such as high temperature, dust, and closed high pressure.

A baffle 16 is hinged at the rear of the mounting seat 3, and a steel wire rope 17 is connected to the lower end of the baffle 16, and the other end of the steel wire rope 17 is wound around a roller 18, and the roller 18 is rotatably connected to the articulated seat 2 through rotating shafts fixed at both ends thereof, one of the rotating shafts is connected to the output shaft of the No. 2 motor 19, and the No. 2 motor 19 is fixedly mounted on the articulated seat 2, and the other rotating shaft extends out of the articulated seat 2 and is equipped with a No. 2 encoder 20, and a capacitive sensor 21 is arranged on the lower side of the entrance of the furnace chamber 23, and the No. 1 motor 7, the No. 2 motor 19, the No. 1 encoder 6, the No. 2 encoder 20 and the capacitive sensor 21 are all electrically connected to the control console 22.

[0022] A coke pushing car vibration reduction method includes four stages:

[0023] In the first stage, the coke pusher driver starts the coke pusher, the coke pusher rod 1 extends toward the furnace 23, and the vibration reduction device moves normally with the coke pusher rod 1. In this stage, the coke pusher has no vibration, the vibration reduction device does not move, and the steel cable is in a relaxed state.

[0024] In the second stage, the vibration reduction device moves with the coke pushing rod 1 to the front of the furnace 23, and the baffle 16 contacts the capacitive sensor 21 at the upper end of the rear side of the furnace 23. After the capacitive sensor 21 detects the signal, it transmits the signal to the control console 22. The control console 22 controls the No. 1 motor 7 and the No. 2 motor 19 to rotate forward. The No. 1 motor 7 rotates forward to drive the No. 1 rotating shaft 5 to rotate forward. The active bevel gear 8 on the No. 1 rotating shaft 5 drives the driven bevel gear 9 to rotate, and then drives the No. 2 rotating shaft 10 to rotate. Since the No. 2 rotating shaft 10 is threadedly connected with the sleeve 12, and the sleeve 12 is restricted by the slider 14 to only move up and down, the sleeve 12 drives the sliding shoe 13 to descend when the No. 2 rotating shaft 10 rotates, and the No. 2 motor 19 rotates forward to drive the roller The wheel 18 winds the steel wire rope 17 to realize the lifting of the baffle 16. In this process, the number of rotations of the No. 1 motor 7 and the No. 2 motor 19 is counted by the No. 1 encoder 6 and the No. 2 encoder 20 respectively. When the number of rotations reaches the set value, the signal value control console 22 is transmitted. The No. 1 motor 7 and the No. 2 motor 19 are controlled by the control console 22 to stop the forward rotation. When the No. 1 motor 7 stops rotating forward, the sliding shoe 13 just contacts the upper surface of the furnace 23. The sliding shoe 13 is accurately lowered by the cooperation of the control console 22 and the No. 1 encoder 6, avoiding the violent collision and impact between the sliding shoe 13 and the furnace 23. When the No. 2 motor 19 stops rotating forward, the baffle 16 is lifted to the specified height.

[0025] In the third stage, the coke pushing vehicle drives the coke pushing rod 1 to continue to move forward and the coke pushing work begins. After the coke pushing is completed, the vibration reduction device extends out of the furnace 23 together with the coke pushing rod 1.

[0026] In the fourth stage, the coke pushing car driver retracts the coke pushing rod 1 and controls the No. 1 motor 7 to reverse through the control console 22 to lift the sliding shoe 13. When the sliding shoe 13 is lifted to the initial height, the No. 1 motor 7 is automatically stopped through the feedback of the No. 1 encoder 6. When the vibration reduction device withdraws from the entrance side of the furnace 23 together with the coke pushing rod 1, the coke pushing car driver controls the No. 2 motor 19 to rotate in the opposite direction through the control console 22 to lower the baffle 16. When the baffle 16 is lowered to the specified height, the No. 2 motor 19 is automatically stopped through the feedback of the No. 2 encoder 20 to complete the lifting of the sliding shoe 13 and the lowering of the baffle 16.
