Description

Technical Field

[0001] The present invention relates to the technical field of coking equipment, and particularly to a detachable traveling crane rail connector and a usage method thereof. Background Art

[0002] With the development of the metallurgical industry, many changes have taken place in the layout of coke ovens and the coke quenching methods. In the current coke oven layout, when there are multiple coke ovens and the full dry quenching method is adopted, there are various coke quenching options for coke. However, in the coking mobile equipment supporting the coke oven, there are certain problems with the operation of the coke quenching car. Due to the process design requirements, usually only one group of coke quenching cars runs on the coke quenching line during production. Once a vehicle has a major failure, since the standby vehicle is placed in an off-line position, on-line transfer cannot be achieved, and the standby vehicle needs to be transferred through a car transfer table.

[0003] When the coke quenching car is operating, when it passes through the joint of the track on the car transfer table and the original track, it will generate a strong impact vibration. This vibration causes strong impact damage to the wheel bearings, resulting in equipment damage, increasing the maintenance or vehicle replacement time, and seriously affecting the stable operation of production.

[0004] Traditional methods for solving the track joint problem, such as welding the track joints (thermit welding or manual welding) to achieve seamless connection, are not applicable in this scenario because the car transfer table needs to frequently switch the standby vehicle, and the track joints must be designed in a detachable and connectable manner. Therefore, the existing technology has deficiencies in meeting the requirements of smooth operation of the coke quenching car and detachable track joints. Summary of the Invention

[0005] The purpose of the present invention is to provide a detachable traveling crane rail connector and a usage method thereof to solve the problems existing in the above-mentioned prior art, with a simple structure, convenient use, effectively reducing impact vibration, and effectively ensuring the safe and stable operation of the coke quenching car.

[0006] To achieve the above purpose, the present invention provides the following solution:

DETAILED DESCRIPTION OF THE INVENTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] The purpose of the present invention is to provide a detachable traveling track connector and a usage method thereof to solve the problems existing in the above-mentioned prior art, with a simple structure, convenient use, effectively reducing impact vibration, and effectively ensuring the smooth operation of the coke quenching car.

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Embodiment 1

[0029] This embodiment provides a detachable traveling track connector 100, as Figures 1 to 4 shown, including: a transfer car track joint 1, a track connector body 2, a coke oven area track joint 3, and a connecting member. The transfer car track joint 1 is provided with a first inclined surface; both ends of the track connector body 2 are respectively provided with a second inclined surface and a third inclined surface; the coke oven area track joint 3 is provided with a fourth inclined surface; the connecting member is detachably and fixedly connected to the transfer car track joint 1, the track connector body 2, and the coke oven area track joint 3 respectively, so that the first inclined surface and the second inclined surface correspond and are parallel to each other and form a first inclined gap between the first inclined surface and the second inclined surface, the third inclined surface and the fourth inclined surface correspond and are parallel to each other and form a second inclined gap between the third inclined surface and the fourth inclined surface. By setting the structure of inclined surface docking and forming an inclined gap, the traditional track connection method (linear joint docking method) is changed. When the vehicle wheels pass by, compared with the traditional track joint form, this inclined gap design changes the contact mode between the wheels and the track joint, from line contact to approximate point contact, which is more conducive to realizing the smooth transition of the vehicle through the track joint, reducing impact vibration, protecting the wheel bearings, extending the service life of the equipment, and ensuring the safe and stable operation of the traveling crane. At the same time, the detachable connection method meets the requirement of flexible disassembly and assembly of the track connection when the transfer car 5 transfers spare vehicles.

[0030] In a preferred solution of this embodiment, a first vertical surface and a second vertical surface are respectively arranged at two ends of the first inclined surface, and a third vertical surface and a fourth vertical surface are respectively arranged at two ends of the second inclined surface. The first vertical surface and the third vertical surface are corresponding and parallelly arranged, and the second vertical surface and the fourth vertical surface are corresponding and parallelly arranged. The vertical surface structures arranged correspondingly and parallelly at both ends of the inclined surface play a role of temporarily positioning and guiding the inclined surface. When installing the track connector, it can make the docking of the car transfer track joint 1 and the track connector body 2 more accurate and rapid, improving the installation efficiency and installation accuracy. On the other hand, this structure can enhance the stability at the joint. When the vehicle is running on the track, the vertical surface can bear a part of the lateral force and longitudinal force from the vehicle, preventing the track joint from undergoing unnecessary displacement or misalignment under the action of the vehicle, and further ensuring the reliability and stability of the track connection.

[0031] In a preferred solution of this embodiment, a fifth vertical surface and a sixth vertical surface are arranged at two ends of the third inclined surface, and a seventh vertical surface and an eighth vertical surface are arranged at two ends of the fourth inclined surface. The fifth vertical surface and the seventh vertical surface are corresponding and parallelly arranged, and the sixth vertical surface and the eighth vertical surface are corresponding and parallelly arranged. Similarly, rapid and accurate positioning can be achieved, facilitating the installation and debugging of components. Moreover, during the operation of the vehicle, the vertical surface structure can enhance the integrity and stability of the track connection, bear part of the force from the vehicle, and avoid affecting the driving safety due to joint loosening or misalignment during the long-term use of the track, further improving the reliability and robustness of the entire track system.

[0032] In a preferred solution of this embodiment, the second inclined surface and the third inclined surface are symmetrically arranged with respect to the central plane of the track connector body 2. The symmetrical arrangement enables the track connector body 2 to have better balance and symmetry when connecting with the track joints at both ends. From a mechanical perspective, when the vehicle travels through the track, the forces exerted on the track connector from the two side tracks and the vehicle can be more evenly distributed, avoiding local excessive wear or stress concentration caused by uneven force. Thereby, the service life of the track connector is prolonged, the consistency and stability of the track connection performance are ensured, and a more reliable support is provided for the smooth operation of the vehicle.

[0033] In a preferred solution of this embodiment, the connecting member includes two connecting plates 4, a plurality of first connecting bolts 9, a plurality of first connecting nuts, a plurality of second connecting bolts 7, a plurality of second connecting nuts, a plurality of third connecting bolts 8 and a plurality of third connecting nuts. A plurality of first through holes, a plurality of second through holes and a plurality of third through holes are sequentially arranged on the connecting plate 4. The first connecting bolt 9 is used to pass through the first through hole and the car transfer track joint 1 and is threadedly connected to the first connecting nut to fix the two connecting plates 4 on both sides of the car transfer track joint 1. The second connecting bolt 7 is used to pass through the second through hole and the track connector body 2 and is threadedly connected to the second connecting nut to fix the two connecting plates 4 on both sides of the track connector body 2. The third connecting bolt 8 is used to pass through the third through hole and the coke oven area track joint 3 and is threadedly connected to the third connecting nut to fix the two connecting plates 4 on both sides of the coke oven area track joint 3. The cooperation of a plurality of bolts, nuts and the connecting plate 4 with corresponding through holes realizes a firm and detachable connection between various components. This connection method not only facilitates the installation and disassembly operations of the track connector body 2 on site and can quickly meet the needs of the car transfer table 5 for moving and transferring spare vehicles. Moreover, by fixing with a plurality of bolts and nuts from both sides, the stability and reliability of the connection can be effectively improved, and under working conditions such as the vibration and impact of frequent vehicle operation, it is ensured that the track connection part will not loosen and disconnect, ensuring the safe operation of the entire track system.

[0034] In a preferred solution of this embodiment, the number of the first fixing bolts is two, the number of the second fixing bolts is two, and the number of the third fixing bolts is two. The number of the first through holes on one connecting plate 4 is two, the number of the second through holes is two, and the number of the third through holes is two. The clear setting of the number of the connecting bolts and the through holes on the connecting plate 4 optimizes the connection structure and strength. The arrangement of two bolts can ensure the connection stability while avoiding the complexity and cost increase caused by excessive bolts. At the same time, the appropriate distribution of the number of bolts can make the fastening forces received by each part of the track connection evenly distributed, preventing problems such as joint loosening caused by insufficient local fastening force or track deformation caused by excessive local fastening force, so as to ensure the long-term stable and reliable operation of the entire track connection system.
