Description

Technical Field

[0001] The invention belongs to the field of scraper conveyors, and specifically relates to a mobile scraper conveyor. Background Art

[0002] At present, there are two main types of coke conveyors used on the coke blocking and pushing machines of the coking plant of the steel company: the first type uses multiple scraper conveyors for joint transportation. After the material is fed from the No. 1 scraper, it is first horizontally lifted and then enters the No. 2 scraper, to the No. 3 scraper, and finally unloaded. The No. 4 scraper returns part of the leaked material to the No. 1 scraper. This set of ash conveying system has the disadvantages of long ash conveying cycle, high equipment cost, high maintenance cost and difficulty, and large space occupation. When encountering large pieces of coke, it is easy to cause the chain to get stuck. The conveying chain is very long. After long-term use, the chain is stretched and seriously worn.

[0003] The second is the tipping bucket conveying. After the material is discharged from the guide plate of the furnace frame, it enters the receiving hopper below. There is a large amount of cooling water in the hopper to cool the coke. After the material is received, the hydraulic cylinder drives the hopper to flip upward and pour the material into the right discharge trough, and then the trolley moving up from below takes the material away. This ash conveying system is used on the improved pushing and blocking coke car, which reduces the conveying chain, increases the space in front of the furnace, and reduces the equipment cost and maintenance cost. However, this equipment also has the following disadvantages: when the receiving bucket flips, more water and some floating materials will be spilled outside due to shaking. In addition, the equipment is fully open, and a large amount of smoke and steam will float in the air during the feeding process, which does not meet environmental protection requirements. Summary of the invention

[0004] In order to solve the problem that the existing scraper conveyor is not stable enough and easily damaged during use, the present invention provides a mobile scraper conveyor, which can realize all actions such as receiving, moving and conveying materials, and is fully closed. The equipment is light in weight and runs smoothly, reducing the probability of conveyor failure.

[0005] In order to achieve the above object, the present invention is achieved through the following technical solutions:

[0006] A mobile scraper conveyor includes a shell, characterized in that: the shell is arranged obliquely upward from left to right, the left end of the shell is a feed port, and the right end is a discharge port, a pair of tail sprockets and a pair of head sprockets are rotatably mounted on both sides of the left and right ends of the shell, the outer rings of the tail sprocket and the head sprocket are respectively covered with transmission chains, and a scraper is installed between the chains; the head sprockets are respectively fixedly mounted on the head shaft, the two ends of the head shaft are respectively rotatably mounted on the shell through the first bearing, the head shaft is fixedly mounted with an auxiliary sprocket, the rightmost end of the shell is installed with a motor, and the protruding shaft end of the motor An auxiliary sprocket is fixedly mounted, and the outer rings of the two auxiliary sprockets are respectively mounted with auxiliary chains; more than two pulleys are installed on the body on the side of the shell, one end of the wire rope is fixed to the left end of the shell, and the other end thereof passes through the pulleys from left to right in sequence and then goes down from the rightmost pulley to be connected to the end of the extension rod of the hydraulic cylinder; guide rails are respectively arranged on the body on both sides of the shell, and rollers and guide wheels are respectively installed on both sides of the shell, and when the wire rope pulls the shell, the rollers roll along the top and bottom surfaces of the guide rails respectively, and the guide wheels roll along the side walls of the guide rails respectively.

[0007] It is further characterized by:

[0008] The first bearing is mounted on a movable plate, a slider is provided on the movable plate, and the slider can be moved along a slide groove on the baffle plate in the same direction as the auxiliary sprocket. One end of the screw rod is connected to the movable plate, and the other end passes through the screw rod seat on the shell, and a nut is sleeved on the end of the screw rod. The baffle plate is mounted on the outer side of the shell, and a sealing strip is pressed between the baffle plate and the shell.

[0009] The rollers are rotatably mounted on one end of the roller shaft through bearings, and an inner fixing plate and an outer fixing plate are mounted on the other end of the roller shaft. The side wall of the housing is clamped and fixed between the inner fixing plate and the outer fixing plate, and an adjustment pad is arranged between the inner fixing plate and the outer fixing plate.

[0010] The guide wheel shaft passes through the guide wheels respectively to rotatably mount the guide wheels on the guide wheel seats, one side of the guide wheel seats is mounted on a mounting plate, and the mounting plate is mounted on the side of the housing;

[0011] The transmission chain is a small pitch roller chain;

[0012] The tail sprockets are rotatably mounted on the tail shaft via bearings, and both ends of the tail shaft are fixedly mounted on the housing;

[0013] The shell is fully covered and has two smoke exhaust pipes welded thereon.

[0014] The beneficial effects of the present invention are as follows: the material enters the equipment from the leftmost end, and the rotation of the motor drives the transmission chain and the scraper to scrape the coke from the feed port at the tail of the machine to the discharge port at the head of the machine diagonally upward. When there is no more material at the feed port, the wire rope pulls the shell to move as a whole, retracts it, and waits for the next material to be transported. It can realize all actions such as receiving, moving, and conveying materials, and is fully closed. The equipment is light in weight, runs smoothly, and reduces the probability of conveyor failure. The sealing strip, the first bearing, and the tensioning screw are integrated into one, which reduces the volume required. Only the nut needs to be rotated to drive the screw and the first bearing to move, and the head shaft and the head sprocket will tighten the transmission chain accordingly, so as to achieve the tension of the transmission chain and ensure the transmission effect. The rollers on both sides of the shell realize the movement of the equipment along the diagonal upward direction, and the guide wheels ensure the stable operation of the equipment. A small pitch roller chain is used in the design, with small rolling friction running resistance, small chain rotation radius, and high strength. The tail shaft ensures that the transmission chains on both sides are twisted synchronously and are not prone to bending. BRIEF DESCRIPTION OF THE DRAWINGS
