Description

Technical Field

[0001] The utility model relates to the technical field of steel industry, in particular to an automatic device for safely and accurately connecting a coke tank car. Background Art

[0002] The coke dry quenching drum (CDQ) is a specialized piece of equipment used to load the red-hot coke pushed out of the carbonization chamber. After a period of use, the drum needs to be taken offline for maintenance. To do this, the electric locomotive is driven onto the transfer platform to unload the drum. The drum is placed atop the drum car. The electric locomotive's active operation and the drum car's passive operation are achieved by dragging the drum car. One end of the rod is fixed to the electric locomotive. When the rod approaches the drum car, a person enters the vehicle's track area and lifts the other end until it fully enters the circular slot. A large bolt is then manually inserted to secure the connection, allowing the drum car to be moved.

[0003] At present, there is no automatic device installed to accurately connect the coke tank car, and the electric locomotive is in motion during the connection process, and personnel are required to perform manual connection operations, which can easily lead to poor connection and easily touch people and cause them to fall into the track and cause injury. This not only affects work efficiency but also poses a safety hazard, thereby increasing the difficulty of the tank emptying operation. Summary of the Invention

[0004] The main purpose of the utility model is to solve the above-mentioned existing technical problems and provide an automatic device for safely and accurately connecting coke tank cars.

[0005] The specific scheme of the utility model is: an automatic device for safely and accurately connecting coke tank cars, comprising a connecting piece and a connecting rod, the connecting piece and the connecting rod are detachably connected, the interior of the connecting piece is hollowed out and an opening is provided on one side, a protective mechanism is provided on the top of the connecting piece, the protective mechanism comprises a protective shell, the interior of the protective shell is hollowed out and an installation port is provided on one side, a horizontal plate is provided inside the protective shell, an electromagnet is provided on the top of the horizontal plate, a latch is magnetically connected to the bottom of the electromagnet, the top diameter of the latch is larger than the bottom diameter, a through hole a is provided on the horizontal plate and the through hole a is located below the electromagnet, a through hole b is provided on the top of the connecting piece, a through hole c is provided on the bottom end of the connecting piece, a through hole d is provided on the surface of the connecting rod, the through hole a, through hole b, through hole c and the latch are coaxial, a limit switch metal rod is installed on the side wall of the connecting piece and the limit switch metal rod is located on one side of the opening, and the limit switch metal rod is electrically connected to the electromagnet.

[0006] According to the above technical solution, the pin is magnetically fixed by an electromagnet. When the connecting rod contacts the metal rod of the limit switch, the electromagnet is powered off and demagnetized, causing the pin to fall out from under the through-hole a, and the bottom end of the pin passes through the through-hole b, through-hole c and through-hole d in sequence, thereby achieving the effect of connecting the connector and the connecting rod. Since the diameter of the top end of the pin is larger than the diameter of the bottom end, when the pin falls out of the through-hole a, the top end abuts against the through-hole a, preventing the entire pin from slipping out of the through-hole d and becoming unable to be fixed.

[0007] Furthermore, a disassembly opening is provided on the top of the protective shell, and a protective cover is threadedly connected to the top of the protective shell.

[0008] According to the above technical solution, by removing the protective cover, the internal electromagnet can be repaired or replaced through the disassembly opening.

[0009] Furthermore, baffles are provided on both sides of the opening, and the angle between the baffles and the connecting piece is 100°~120°.

[0010] According to the above technical solution, the baffle acts as a guide for the connecting rod, thereby preventing the connecting rod from severely yawing when aligning with the opening.

[0011] Furthermore, an inclined plate is provided inside the connecting member, and two side inclined plates are provided on the top of the inclined plate. The spacing between the two side inclined plates matches the connecting rod, and the angle between the inclined plate and the connecting member is 80°~100°. A through hole e is provided on the inclined plate, and the through hole e is coaxial with the through hole c.

[0012] According to the above technical solution, a guide rail can be formed by the inclined plate and the two side inclined plates, so that the connecting rod can move between the two side inclined plates, making it easier for the through hole d to be aligned with other through holes, and more accurately touching the limit switch metal rod on the side wall. At the same time, since the connecting rod is installed on the electric locomotive due to weight reasons, one end will tilt downward, so the inclined plate is provided with an angle so that it can maintain a horizontal vertical state when passing through the opening, which is convenient for fixing operations.

[0013] Compared with the existing technology, the utility model has the following advantages: the automatic device for safely and accurately connecting the coke tank car can realize accurate, fast and safe automatic connection with the connecting rod between the coke tank car, avoiding traditional manual operation, reducing the safety of operation, reflecting the practicality and reliability of the automatic device for safely and accurately connecting the coke tank car, and at the same time improving the efficiency of the tank emptying operation.

[0021] See also Figure 1-6The present embodiment is an automatic device for connecting a coke tank car safely and accurately. It is composed of a connecting piece 1 and a connecting rod 2. The connecting piece 1 is used to be welded at one end of the coke tank car, and the connecting rod 2 is arranged at one end of the electric locomotive. The connecting piece 1 is detachably connected to the connecting rod 2. The interior of the connecting piece 1 is hollowed out and an opening 3 is provided on the outside. A protective mechanism is installed on the top of the connecting piece 1. The protective mechanism includes a protective shell 4. The protective shell 4 can effectively protect the electromagnet 5 from being washed by rain when working outdoors. The interior of the protective shell 4 is hollowed out and a mounting opening 6 is hollowed out on the outside. A horizontal plate 7 is welded inside the protective shell 4. An electromagnet 5 is installed on the top of the horizontal plate 7. The bottom end of the electromagnet 5 is magnetically connected to a latch 8. The latch 8 is cylindrical and the top diameter is larger than the bottom diameter. A through hole a9 is hollowed out on the horizontal plate 7 and the through hole a9 is located below the electromagnet 5. The diameter of the through hole a9 matches the maximum diameter of the latch 8, so that the top end of the latch 8 can pass through the through hole a9 and be magnetically connected to the electromagnet 5. A through hole b10 is provided on the top of the connecting piece 1. The diameter of hole b10 is smaller than the maximum diameter of the bolt 8. Therefore, when the bolt 8 is fully inserted into all the through holes, the through hole b10 abuts against the bolt 8 to prevent it from falling out. The mounting opening 6 is located on one side of the through hole b10. When the bolt 8 is restored to be connected to the electromagnet 5, the bolt 8 can be pushed upward through the mounting opening 6 to separate it from the through hole and the electromagnet 5. The bottom end of the connector 1 is provided with a through hole c11, the surface of the connecting rod 2 is provided with a through hole d12, the through holes a9, the through holes b10, The through hole c11 is coaxial with the latch 8, which facilitates the insertion and fixation of the latch 8. A limit switch metal rod 13 is installed on the side wall of the connector 1, and the limit switch metal rod 13 is located parallel to the left side of the opening 3. The limit switch metal rod 13 is electrically connected to the electromagnet 5, so that when the limit switch metal rod 13 is touched by the connecting rod 2, the electromagnet 5 can be powered off and demagnetized. In addition, it should be noted that the limit switch metal rod 13 and the electromagnet 5 can be purchased and used directly in the market.

[0022] Furthermore, a disassembly port 14 is provided at the top of the protective shell 4, and a threaded groove 15 is provided at the outer circle of the disassembly port 14. A protective cover 16 is threadedly connected to the top of the protective shell 4. An external thread 17 is provided at the bottom end of the protective cover 16 and matches the threaded groove 15, so that the protective shell 4 is threadedly connected to the protective cover 16, which facilitates maintenance of the electromagnet 5 in the protective shell 4.

[0023] Furthermore, baffles 18 are welded on both sides of the opening 3 , and the included angle between the baffles 18 and the side wall of the connecting member 1 is 100°~120°. When the connecting rod 2 yaws, the baffles 18 can guide the connecting rod 2 into the opening 3 .

[0024] Furthermore, an inclined plate 19 is welded inside the connecting member 1, and the center line of the inclined plate 19 coincides with the center line of the bottom plate of the connecting member 1, and the inclined plate 19 extends 255 mm outward from the opening 3. Two side inclined plates 20 are provided at both ends of the top of the inclined plate 19, and a guide rail is formed between the two side inclined plates 20. The spacing between the two side inclined plates 20 matches the connecting rod 2, so that the naturally hanging connecting rod 2 is lifted upward by the inclined plate 19, so that the connecting rod 2 is in a relatively flat state when fixed by the pin 8, and the connecting rod 2 is limited by the two side inclined plates 20, so that the through hole d12 can be aligned with other through holes and better touch the limit switch metal rod 13. The angle between the inclined plate 19 and the connecting member 1 is 80°~100°, which is more convenient and accurate. A through hole e21 is hollowed out on the inclined plate 19, and the through hole e21 and the through hole c11 are on the same axis, which is convenient for the pin 8 to be inserted and fixed.

[0025] The working principle of this embodiment is as follows: during operation, the electric locomotive drives the connecting rod 2 to approach the connecting member 1. When the connecting rod 2 has serious yaw, the baffle 18 guides the connecting rod 2 into the opening 3. At the same time, the connecting rod 2 is aligned with the inclined plate 19 and moves into the opening 3, so that the connecting rod 2 is kept between the two side inclined plates 20. When the through hole d12 on the connecting rod 2 coincides with other through holes, one end of the connecting rod 2 touches the limit switch metal rod 13. At this time, the movable part of the limit switch metal rod 13 will be subjected to pressure and displaced, causing the contact between the fixed contact and the movable part to be disconnected, interrupting the circuit connection. At this time, the electromagnet 5 is de-energized and demagnetized. The top end of the pin 8 first falls out of the through hole a9 due to gravity, and the bottom end passes through the through hole b10, through hole d12 and through hole e21 in sequence, and finally passes through the connecting member. The through hole c11 at the bottom of the component 1a, when it is fully penetrated, the top of the pin 8 abuts against the through hole b10, and the connection between the connecting component 1 and the connecting rod 2 is completed, avoiding the traditional manual connection, which is not only inefficient but also dangerous, thereby improving work efficiency and safety. When the connecting component 1 and the connecting rod 2 are separated again, the pin 8 is manually extended into the installation opening 6 and lifted upward. When the pin 8 is connected to the electromagnet 5, the electromagnet 5 is energized and the electromagnet 5 is adsorbed again. At this time, the connecting rod 2 can be moved out of the connecting component 1. When disassembling for maintenance or replacing the electromagnet 5, the protective cover 16 can be rotated to remove it, and the opposite operation can be performed when reinstalling it. At the same time, when operating outdoors, the protective cover 16 and the protective shell 4 can effectively prevent the internal electromagnet 5 from being washed by rainwater, thereby improving service life and convenience of use.
