Detailed Description

In the following description, numerous technical details are set forth in order to provide a better understanding of the present application. However, it will be understood by those skilled in the art that the technical solutions claimed in the present application may be implemented without these technical details and with various changes and modifications based on the following embodiments.

The following outlines some of the innovative points of the embodiments of the present application:

the lifting track comprises a fixed frame 1, a lifting frame 2, a safety collision fence mechanism 3, an equal-height supporting column 4, a lifting driving device 5, a vertical locking mechanism 6 and a horizontal locking mechanism 7.

The fixed frame 1 is a fixed steel structure in the whole lifting rail, and comprises a first fixed frame 101 and a second fixed frame 102 which are respectively erected at the left side and the right side of the lifting frame. The first and second fixed frames are each provided at the center thereof with a C-shaped guide rail 110 extending in the vertical direction, and the two C-shaped guide rails 110 are disposed to face each other for embedding a composite guide wheel structure on the lifting frame therein and traveling in the longitudinal direction. Each fixed frame is provided with a horizontal locking mechanism on two sides respectively in the direction parallel to the track, namely, the two fixed frames have 4 horizontal locking mechanisms in total and are used for locking the lifting frame when the lifting frame is at a high position, so that the levelness and elevation of a track surface are ensured, and the trolley is ensured to be transited on the high-position track stably. The horizontal locking mechanism is preferably 4 horizontal locking cylinders (71.

The hoisting frame 2 is a part displaceable in the longitudinal direction. As shown in fig. 1 and 4, the lifting frame is fitted at the top with two parallel rails (201, 202) for supporting the stokehold carriage and limiting its trajectory. At a position between the two rails, parallel to the rails, two vertical locking mechanisms 6, preferably vertical locking cylinders (61. When the trolley travels to the lifting frame, the oil cylinder of the locking mechanism jacks up to lock the trolley, so that the safety of the stokehole trolley is ensured when the lifting frame is lifted. Two sides of the lifting frame are provided with a composite guide wheel (211, 212) and a composite guide wheel (221. When the lifting frame is mounted on the fixed frame, the composite guide wheels on each side respectively cooperate with the C-shaped guide rails 110 on the adjacent fixed frame, and the longitudinal lifting or lowering of the lifting frame is achieved by the sliding of the composite guide wheels therein.

The height positioning sensor 8 is vertically arranged near the track and used for positioning the height of the platform; including a vertical displacement sensor 81 for transmitting a platform height signal and a position proximity switch 82 for transmitting a height confirmation signal.

As shown in fig. 1 and 3, 4 equal-height supporting columns 9 are located at the bottom of the lifting frame to support the lifting frame, that is, when the track body is used at a low position (standard position) and the furnace front car is handed over, four ends of the lifting frame are supported, the levelness and elevation of the track surface are ensured, and the trolley is ensured to be smoothly transited to the lifting frame. The lifting driving device 5 is positioned at the central position of the bottom of the lifting frame and provides a lifting force for the lifting frame. The lifting drive 5 is preferably a jacking cylinder.

The safety fence mechanism 3 is a link mechanism composed of three rods, as shown in fig. 1 and 4. The collision fence 301 is horizontally erected on two fixed frames. One end of the first sliding rod 302 is hinged with the lifting frame 2, and the other end is hinged with the collision fence 301; one end of the second sliding rod 303 is connected with the collision rail 301, and the other end is hinged with a fixed frame 1. When the lifting frame is lifted upwards, the first sliding rod jacks up the collision fence 301, and the collision fence is turned upwards by taking one end part as a vertex, namely is opened. Through the link mechanism, the collision rail is closed as shown in the figure when the track is at a low position, so that a trolley on the track at the high position is prevented from falling onto the low track, or a transfer trolley or a stokehold trolley is prevented from falling; when the rail is at the high position, the collision fence is opened, and a trolley on the rail at the high position can drive onto the equipment.

Example 1: use the lift track of this application to promote low level stokehold car to high-order. When the stokehole car is stopped on the track of the lifting frame 2, the vertical locking oil cylinder (61. At this time, the safety fence mechanism 3 is in a closed state, that is, the striker 301 is transversely arranged between the steel structures of the fixed frame, so as to prevent the furnace front car from falling, as shown in fig. 6. Under the lifting force of the jacking oil cylinder (namely the lifting driving device 5), the composite guide wheel slides upwards in the C-shaped guide rail longitudinally, the whole lifting frame rises, and when the position of the sequence positioning proximity switch 82 is reached, the lifting frame stops rising, namely the height positioning sensor confirms that the high position is reached. The horizontal locking oil cylinder (71; 72; 73. At this time, the fence 301 is already in the open state by the jacking-up of the first slide bar 302, i.e., the fence 301 is raised, as shown in fig. 7. The vertical locking oil cylinder 3 retracts, and the stokehole vehicle travels.

Example 2: use the lift track of this application to transport and come from high-order stokehold car. The empty lifting frame is at a low position, and the safety collision fence mechanism is at a closed state at the moment, so that the furnace front vehicle at a high position is prevented from falling. Under the lifting force provided by the jacking oil cylinder, the lifting frame is arranged on the jacking oil cylinder, the composite guide wheel longitudinally slides upwards in the C-shaped guide rail, the whole lifting frame is lifted, and when the position of the sequence positioning approach switch 82 is reached, the lifting frame stops lifting, namely, the height positioning sensor confirms that the high position is reached. The horizontal locking oil cylinder (71; 72; 73. At this time, the fence 301 is already in the open state by the jacking-up of the first slide bar 302, i.e., the fence 301 is raised, as shown in fig. 7. The stokehole vehicle positioned at a high position enters the track. The horizontal locking cylinders (71.
