Abstract
Description
Technical Field
[0001] The utility model relates to a device for preventing a sintering machine trolley from reversing, belonging to the technical field of metallurgical equipment. Background Art
[0002] The sintering machine system uses exhaust sintering to sinter the iron-containing materials, flux, fuel, etc. into blocks by adding water and pelletizing the mixture for use in the blast furnace. As the main equipment of the sintering system, the stable operation rate of the sintering machine directly affects the operating efficiency of the sintering system.
[0003] There are belt sintering machines, ring sintering machines and walking beam sintering machines. The walking beam sintering machine does not run continuously. After the trolley runs to the right position, a ferry is needed to transport the next trolley to run alternately. When the ferry transfers the trolley, the previous trolley is prone to slipping, affecting the continuous operation of the walking beam sintering machine.
[0004] Therefore, how to effectively prevent the walking sintering machine trolley from reversing has become an urgent problem to be solved by relevant technicians. Utility Model Content
[0005] The utility model aims to provide a device for preventing a sintering machine trolley from reversing, which can effectively prevent a step-type trolley from reversing after operation, causing the next trolley to be unable to operate normally, and solve the problems existing in the background technology.
[0006] The technical solution of the utility model is:
[0007] A device for preventing a sintering machine trolley from reversing comprises a trolley, trolley wheels and a trolley running track. The trolley is a stepping trolley. A stop block is arranged on the trolley running track. The stop block is a right triangle or a right trapezoid. The hypotenuse of the right triangle or the oblique waist of the right trapezoid faces the running direction of the trolley. The stop block is rotatably connected to the trolley running track through a pin shaft. A compression spring is arranged between the stop block and the trolley running track, and a limit block is arranged under the stop block.
[0008] One end of the compression spring is connected to the stop block, and the other end of the compression spring is connected to the trolley running track.
[0009] The compression spring is located on the vertical side of the right triangle or on one side of the straight waist of the right trapezoid.
[0010] The height of the stop block is smaller than the radius of the trolley wheel.
[0011] The limiting block below the stop block is fixed on the trolley running track.
[0012] The limiting block and the pin shaft below the stop block are both close to the acute angle below the right triangle or the right trapezoid.
[0013] The portion where the hypotenuse of the right triangle or the oblique waist of the right trapezoid contacts the trolley running track is in an arc shape.
[0014] The beneficial effects of the utility model are: simple structure, low cost, and can effectively prevent the step-type trolley from slipping after running and reversing to cause the next trolley to be unable to operate normally, thereby improving the operating efficiency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a schematic diagram of the structure of the utility model;
[0016] In the figure: 1, trolley, 2, trolley wheel, 3, trolley running track, 4, stop block, 5, compression spring, 6, pin shaft, 7, limit block. DETAILED DESCRIPTION
[0017] The present invention will be further described below by way of examples with reference to the accompanying drawings.
[0018] See attached Figure 1 A device for preventing a sintering machine trolley from reversing comprises a trolley 1, trolley wheels 2 and a trolley running track 3. The trolley 1 is a stepping trolley, and a stop block 4 is arranged on the trolley running track 3. The stop block 4 is a right triangle or a right trapezoid, and the hypotenuse of the right triangle or the oblique waist of the right trapezoid faces the running direction of the trolley 1. The stop block 4 is rotatably connected to the trolley running track 3 through a pin shaft 6. A compression spring 5 is arranged between the stop block 4 and the trolley running track 3, and a limit block 7 is arranged under the stop block 4.
[0019] In this embodiment, refer to the attached Figure 1 The specific production and operation process is as follows:
[0020] (1) Material preparation
[0021] The stopper 4 is a right-angled trapezoid, made of 20mm thick iron plate, and its size is based on the design of the trolley wheel 2 and the trolley running track 3, including an upper bottom, a lower bottom and two waists, one of which is a straight waist (a right-angle waist) and the other is an oblique waist. The upper half of the oblique waist is an arc that matches the wheel 2, as shown in the attached Figure 1 shown.
[0022] The compression spring 5 has a length of 100 mm and the limit block 7 has a size of 100 mm*50 mm*20 mm.
[0023] (2) Installation method
[0024] The stop block 4 is installed on the trolley running track 3 through the pin shaft 6, so that the oblique waist of the stop block 4 faces the direction of the trolley 1, as shown in the attached Figure 1As shown, the arrow indicates the running direction of the trolley 1; a limit block 7 is reinforced on the acute angle side of the right-angled trapezoid below the stop block 4 to ensure that the stop block 4 cannot run in the reverse direction; a compression spring 5 is installed on the rotating side of the stop block 4, i.e., the straight waist side.
[0025] (3) Working process
[0026] The arrow indicates the running direction of the trolley 1. When the trolley is running, gravity is used to press on the stop block 4. When the stop block 4 rotates, the rear wheels can run normally. After the trolley wheels run, the stop block 4 returns to the starting position under the action of the compression spring 5. When the trolley wheels run in the opposite direction, the stop block 4 cannot rotate under the action of the limit block 7, which plays a role in blocking the trolley from running.
[0027] The beneficial effects of the utility model are:
[0028] The structure is simple and the cost is low. It can effectively prevent the stepping trolley from slipping after running and reversing, causing the next trolley to be unable to operate normally, thereby improving the operating efficiency of the equipment.
