Description

Technical Field

[0001] This utility model relates to a waste coke elevator that can reduce operational failures and facilitate maintenance, belonging to the technical field of coking coal production equipment. Background Technology

[0002] In steel enterprises, after automatic sampling of coke, the waste coke is transported to the coke conveyor belt by a vertically lifting waste material elevator, achieving waste recycling. The bucket of this waste material elevator is directly connected to the lifting wire rope, and the pulley system uses channel steel rails and ordinary traveling wheels. The pulley system is directly installed on the side wall of the bucket, and the ordinary traveling wheels slide within the channel steel rails. During operation, due to the weight of the bucket and the waste coke, as well as the friction of the pulleys, the steel plates on the side wall of the bucket deform severely, and the pulleys deviate significantly from the channel steel rails. This increases the load on the winch, making operation difficult and leading to frequent malfunctions. This seriously affects the normal use of the waste material elevator and the smooth operation of production. Utility Model Content

[0033] This utility model consists of a lifting frame 1, a winch 2, a wire rope 3, a top hanging wheel 4, a guide pulley 5, a round steel slide rail 6, a lifting hopper frame 7, a hopper 8, and a pulley device 9.

[0034] Figure 1 , 2 As shown in Figure 3, the lifting frame 1 is an upright cuboid frame. A winch 2 is installed on the upper end of the lifting frame 1, and a wire rope 3 is wound around the drum of the winch 2. Round steel slides 6 are installed on the inner wall of the lifting frame 1 on opposite front and rear sides. A lifting hopper frame 7 is located between the round steel slides 6. The lower end of the wire rope 3 is connected to the upper end of the lifting hopper frame 7, and the hopper 8 is fixedly connected in the lifting hopper frame 7. Pulley devices 9 are installed at the front and rear of the lifting hopper frame 7, respectively, and the pulley devices 9 are in sliding engagement with the round steel slides 6 on the front and rear sides. In use, the winch 2 pulls the lifting hopper frame 7 upwards via the wire rope 3. The pulley devices 9 of the lifting hopper frame 7 slide along the round steel slides 6, and the lifting hopper frame 7 lifts the hopper 8.

[0035] Figure 1 , 2 As shown in Figure 3, a top sheave 4 is fixed to the front end of the winch 2 at the upper end of the lifting frame 1. The wire rope 3 of the winch 2 is redirected to a vertical direction via the top sheave 4. A guide pulley 5 is installed on the lifting frame 1 below the top sheave 4. The wire rope groove of the guide pulley 5 is aligned with the wire rope groove of the top sheave 4. The guide pulley 5 is located above the front end of the arc-shaped slide 12 of the round steel slide 6. The wire rope 3 is located at the center of the round steel slide 6 via the wire rope grooves of the top sheave 4 and the guide pulley 5. The lower end of the wire rope 3 is connected to the lifting bucket frame 7. When the lifting bucket frame 7 is lifted upwards, the wire rope 3 moves outwards with the lifting bucket frame 7. The function of the guide pulley 5 is to restore the outwardly moved wire rope 3 to the center position opposite to the top sheave 4 along the guide pulley 5.

[0036] Figure 1 , 2As shown in Figure 3, the round steel slide 6 consists of a front slide 10, a rear slide 11, and an arc-shaped slide 12. Each of the front slide 10, rear slide 11, and arc-shaped slide 12 consists of two parallel round steel bars. The front slide 10 and rear slide 11 are fixedly connected to the front and rear of the lifting frame 1, respectively. The upper end of the front slide 10 is the discharge port 13 of the lifting frame 1. The upper end of the rear slide 11 is connected to the lower end of the arc-shaped slide 12. The arc of the arc-shaped slide 12 faces the rear outer side of the lifting frame 1. The front end of the arc-shaped slide 12 is above the upper end of the front slide 10, and the front end of the arc-shaped slide 12 is located in the middle of the two sides of the upper end of the lifting frame 1.

[0037] Figure 1 , 2 As shown in Figure 3, the upper end of the front slide 10 of the round steel slide 6 has a limiting block 14, which is opposite to the pulley device 9 at the front of the lifting hopper frame 7 after it has risen. When the pulley device 9 at the front of the lifting hopper frame 7 moves to the position of the limiting block 14, the limiting block 14 blocks the pulley device 9, and the front of the lifting hopper frame 7 stops at this position. The wire rope 3 continues to pull the lifting hopper frame 7, and the lifting hopper frame 7 will flip with the limiting block 14 as the fulcrum to realize the unloading operation.

[0038] Figure 1 , 2 As shown in Figure 3, a tilting baffle 15 is fixed on the outer side of the hoist frame 1 above the discharge port 13 at the upper end of the front slide 10 of the round steel slide 6. The distance between the tilting baffle 15 and the front end of the arc-shaped slide 12 matches the length of the hopper 8. When the lifting hopper frame 7 is tilted, the tilting baffle 15 blocks the front end of the tilting lifting hopper frame 7 to prevent it from tilting and falling. A top limiter 16 is fixed on the tilting baffle 15, and a bottom limiter 17 is fixed on one side of the lower end of the round steel slide 6. The top limiter 16 and the bottom limiter 17 are respectively connected to the switching circuit of the winch 2. When the upper end of the rising lifting hopper frame 7 and the bottom surface of the falling lifting hopper frame 7 come into contact with the top limiter 16 and the bottom limiter 17 respectively, the top limiter 16 and the bottom limiter 17 are triggered to control the rotation of the winch 2.

[0039] Figure 1 , 2 As shown in Figure 3, a buffer pad 18 is installed on the bottom surface of the lifting frame 1, and the buffer pad 18 is opposite to the bottom surface of the lifting hopper frame 7. The buffer pad 18 can cushion the falling lifting hopper frame 7 and prevent it from being damaged by impact.

[0040] Figure 1 , 4As shown in Figure 5, the lifting hopper frame 7 consists of a base plate 19, a tilting support plate 20, two side plates 21, and a hanger 22. The base plate 19 is a square plate, and the tilting support plate 20 is a rectangular plate. The lower end of the tilting support plate 20 is connected to the front end of the base plate 19, and the plate surface of the tilting support plate 20 is tilted forward. The two side plates 21 are triangular, and their two sides are welded to the two side edges of the base plate 19 and the tilting support plate 20, respectively. The hanger 22 is an N-shaped frame. The lower ends of the two side rods of the hanger 22 are connected to the plate surfaces of the two side plates 21 through short shafts 23, respectively. The horizontal bar of the hanger 22 has a hanger 24 at its center, and the lower end of the wire rope 3 is connected to the hanger hole 24.

[0041] Figure 4 , 5 The display shows that pulley fixing plates 25 are vertically welded to the upper front sides and the lower rear sides of the lifting hopper frame 7. The pulley fixing plates 25 are square plates, and the four corners of the pulley fixing plates 25 have screw holes that connect to the pulley device 9.

[0042] Figure 1 , 6 As shown in Figure 7, the hopper 8 has a square cone structure, with its top surface larger than its bottom surface. The top surface of the hopper 8 is open, and the height of its side walls matches the upper end of the tilting support plate 20 of the lifting hopper frame 7. The bottom surface of the hopper 8 is fixedly connected to the base plate of the lifting hopper frame 7 by connecting bolts. Placing the hopper 8 in the lifting hopper frame 7 avoids deformation and damage to the hopper 8 caused by the wire rope 3 directly pulling it, and also facilitates the maintenance or replacement of the hopper 8.

[0043] Figure 8 , 9 The pulley device 9 consists of a fixed plate 26 and a mounting base 27. The bottom surface of the fixed plate 26 is square, and its screw holes correspond to the screw holes of the pulley fixing plate 25 of the lifting hopper frame 7. Connecting bolts 28 connect the fixed plate 26 to the pulley fixing plate 25 of the lifting hopper frame 7. The front end of the fixed plate 26 is connected to the mounting base 27, which has a vertical sliding groove 29 at its front end. The sliding groove 29 is elongated, and its inner wall has a semi-circular cross-section. The arc of the semi-circle matches the outer diameter of the round steel slide rail 6 of the lifting frame 1. The sliding groove 29 at the front end of the mounting base 27 clamps the outer circumference of the round steel slide rail 6, and the sliding groove 29 at the front end of the mounting base 27 and the round steel slide rail 6 are in sliding engagement. The pulley device 9 slides along the round steel slide rail 5 via the sliding groove 29 at the front end of the mounting base 27.

[0044] Figure 8 , 9As shown in figures 10, 11, 12, 13, and 14, the fixed plate 26 of the pulley device 9 is a stepped flat cylinder. A bearing 30 is fitted around the circumference of the upper flat cylinder. The rear end of the clamping seat 27 is cylindrical, with a circular hole on its end face. The diameter of this hole matches the outer circumference of the bearing 30 fitted around the upper cylinder of the fixed plate 26. The bearing 30 at the front end of the fixed plate 26 and the inner wall of the circular hole at the rear end of the clamping seat 27 are in a rotating fit. A retaining ring 31 is fitted onto the cylindrical part of the fixed plate 26 at the rear end of the bearing 30. The fixed plate 26 and the clamping seat 27 are connected by the bearing 30, allowing them to rotate axially and preventing damage to the pulley device 9 caused by the swinging of the lifting hopper frame 7. A roller frame 32 and ball bearings 33 are installed in the sliding groove 29 at the front end of the clamping seat 27. The sliding groove 29 clamps the round steel slide rail 6 through the roller frame 32 and ball bearings 33, reducing frictional resistance and ensuring smooth sliding.

[0045] Figure 15 , 16 The roller frame 32 has two bent plates at each end, with screw holes in the center of each plate. The two bent plates are clamped on the side walls of the sliding groove 29 at the front end of the holder 27. The front end face of the sliding groove 29 has screw holes that are opposite to the screw holes of the plates of the roller frame 32. The fixing bolts 35 fix the two plates of the roller frame 32 to the front end faces of the side walls of the sliding groove 29. There are multiple rings 34 between the two plates, which are connected by connecting pieces. The multiple rings 34 are placed along the inner wall of the sliding groove 29. Multiple balls 33 are stuck between the rings 34 and the inner wall of the sliding groove 29. The inner diameter of the ring 34 is smaller than the diameter of the ball 33. The top surface of the ball 33 is located outside the ring 34 and contacts the outer circumference of the round steel of the round steel slide 6. The ball 33 and the inner wall of the sliding groove 29 of the holder 27 and the outer circumference of the round steel of the round steel slide 6 are in rolling fit.

[0046] The usage process of this utility model is as follows:

[0047] First, waste coal and coke are discharged into hopper 8. Then, winch 2 is started, and wire rope 3 pulls up the lifting hopper frame 7. The lifting hopper frame 7 rises along the round steel slide rail 6. When the pulley device 9 at the front of the lifting hopper frame 7 moves to the position of the limiting block 14 at the front end of the arc-shaped slide rail 12 of the round steel slide rail 6, the limiting block 14 blocks the pulley device 9, and the front of the lifting hopper frame 7 stops at this position. The wire rope 3 continues to pull up the lifting hopper frame 7, and the lifting hopper frame 7 will flip with the limiting block 14 as the fulcrum and begin to discard the material. At the same time as discarding the material, the top limiter 16 issues a command, and winch 2 rotates in the opposite direction. The lifting hopper frame 7 and hopper 8 descend to the bottom under the action of gravity. When they touch the bottom limiter 17, winch 3 stops running and enters the next waste collection state.

[0048] When the ball bearings 33 or rollers 32 installed on the pulley device 9 are worn, remove the connecting bolts 28 of the pulley fixing plate 25 that connects the pulley device 9 and the lifting hopper frame 7, remove the pulley device 9, and replace its vulnerable parts.
