Description

Technical Field

[0001] The utility model relates to the technical field of sintering equipment, and particularly relates to a rapid replacement device for a sintering machine trolley. Background Art

[0002] During the sintering operation, the sintering machine trolley is in a high-temperature environment and operates continuously in a long-term cycle. Its operation intensity is high, and the probability of failure is relatively high. Common problems are mostly damage to the grate bars and heat insulation parts of the trolley, bearing wear, wheel loosening, outward flashing of the railing, fracture or missing of the girder bolts, shaft runout, etc. The replacement and repair of the trolley after a failure are problems faced by each iron and steel enterprise. Currently, the replacement of the trolley mainly relies on a crane for lifting operations. During the lifting operation of the crane, 7 - 8 people need to cooperate. The trolley is heavy and large in size, which brings difficulties to the lifting operation, and accidents such as injury to people or damage to equipment are likely to occur, with great potential safety hazards. In addition, the replacement time of the trolley by the lifting method is long. At this time, the sintering process of the materials on other trolleys in the sintering section is in a continuous state, which is likely to cause overburning of the materials, affecting the strength of the sintered materials and subsequent smelting operations. When replacing in the sintering section, it will also cause the induced draft fan to draw in cold air from the vacant position of the trolley, and when it meets the high-temperature gas in the induced draft system, it is easy to cause water vapor condensation, affecting the subsequent equipment.

[0003] The utility model is used to overcome the defects of the existing technology and provide a rapid replacement device for a sintering machine trolley to solve the problems mentioned in the background art.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0005] A rapid replacement device for a sintering machine trolley includes a mobile platform and a first track. The mobile platform is provided with rollers matching the first track; the mobile platform and the first track are located below the turning-back section of the trolley running track, and the first track is perpendicular to the trolley running track; the turning-back section of the trolley running track is a discontinuous two-section structure, successively composed of a first turning-back section and a second turning-back section.

[0006] The first turning-back section and the second turning-back section of the trolley running track are inclined, with a high point at the discontinuous part, and extending from the discontinuous part to both sides, the track height gradually decreasing.

[0019] The present utility model will be further described in detail below in conjunction with the drawings and embodiments.

[0020] As Figures 1-4 shown, the present utility model includes a mobile platform 1 and a first track 2. A roller matching the first track 2 is arranged on the mobile platform 1. The mobile platform 1 and the first track 2 are located below the turning section of the trolley running track 3, and the first track 2 is perpendicular to the trolley running track 3.

[0021] The turning section of the trolley running track 3 is a discontinuous two-section structure, which is successively composed of a first turning section 3-1 and a second turning section 3-2. That is, there is a gap on the turning section of the trolley running track 3. The distance between the first turning section 3-1 and the second turning section 3-2, that is, the length of the gap, is the length of a trolley. A filling track 1-1 is arranged on the mobile platform 1. The filling track 1-1 is perpendicular to the first track 2, matches the gap at the discontinuous part of the trolley running track 3, and is movably connected to the first turning section 3-1 and the second turning section 3-2.

[0022] A standby track is arranged on one side of the trolley running track 3. The standby track is used to transfer and place the repaired trolley and the replaced faulty trolley. The repaired trolley is placed in an inverted manner with the wheels facing up on the standby track.

[0023] The trolley running track is a circular track. The upper half section is a sintering section, and the lower half section is a turning section. Replace at the turning section

[0024] The standby track can be designed with the following scheme: The standby track is composed of a second track 4. The second track 4 is perpendicular to the first track 2 and can be connected to the filling track 1-1. Two groups of the second track 4 are arranged on both sides of the first track 2 respectively. A ramp track can be arranged on the side of the second track 4 to be connected to it for the convenience of the trolley to go up and down. The wheels of the repaired trolley are inverted on the second track 4, and it can be in a standby state when the sintering machine trolley has no fault. Therefore, its flipping and inversion are prepared in advance when the sintering machine trolley has no fault, which does not affect the replacement time of the trolley. When the trolley is repaired and placed in standby, it can be placed in an inverted state by the overhead crane.

[0025] When replacing the trolley: First step, the repaired trolley is first placed on a group of second tracks 4. Second step, the faulty trolley is run to the filling track 1-1. Third step, the filling track 1-1 carrying the faulty trolley is removed from the discontinuous part of the trolley running track 3 and connected to another group of second tracks 4. Fourth step, the faulty trolley is moved to the second track 4. Fifth step, the repaired trolley is moved from the second track 4 to the filling track 1-1. Sixth step, the filling track carrying the repaired trolley is moved to the turning section of the trolley running track 3.

[0026] Each of the above-mentioned first track 2, trolley running track 3, and second track 3 includes 2 mutually parallel tracks.

[0027] The trolley needs to be positioned on the filling track 1-1, and the following design can be adopted: A positioning component 5 is provided on the filling track 1-1. The positioning component 5 is composed of a guiding cylinder 5-1, a guide rod 5-2, and a driving mechanism; The guiding cylinder 5-1 is arranged on the side of the filling track 1-1, and a vertical guiding hole is provided thereon. The guide rod 5-2 is matched with the guiding hole. The lower end of the guide rod 5-2 is connected to the driving mechanism, and the upper end of the guide rod 5-2 is provided with an arc surface. When the guide rod 5-2 rises, the arc surface is in pressing contact with the circumferential surface of the wheel of the trolley 6 to form a stop for the wheel of the trolley 6.

[0028] The selection of the driving mechanism and the layout of the positioning component can adopt the following design: The driving mechanism is a worm and gear mechanism, an electric cylinder, or a hydraulic cylinder; 2 groups of positioning components are arranged on a single track of the filling track 1-1 to position the front and rear wheels of the trolley 6 respectively.

[0029] To prevent the trolley on the trolley running track 3 from being pushed towards the discontinuous part, the following thrust prevention component can be set: Thrust prevention components are provided at the ends of the first turning section 3-1 and the second turning section 3-2. The structure of the thrust prevention component is the same as that of the positioning component 5, and is used to thrust and position the wheels of the trolley close to the discontinuous part of the turning section of the trolley running track 3.

[0030] To achieve the thrust on the trolley at the discontinuous part of the trolley running track 3, the first turning section 3-1 and the second turning section 3-2 can also be inclined. The discontinuous part is the high point, and the height of the trolley running track 3 gradually decreases from the discontinuous part to both sides. The inclination angle of the inclined setting should not be too large. The included angle between the first turning section 3-1, the second turning section 3-2 and the horizontal plane can be between 2-3 degrees.

[0031] The driving of the mobile platform can adopt the following design: A driving motor, a speed reducer, and a gear are sequentially arranged on the mobile platform 1. A rack is arranged between the two tracks of the first track 2. The rack is arranged parallel to the first track 2 and meshes with the gear. The driving motor drives the mobile platform 1 to move on the first track 2.
