[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] Example 1
[0025] This embodiment provides a detachable trolley track connector 100, such as... Figures 1-4 As shown, the system includes: a transfer platform track joint 1, a track connector body 2, a coke oven area track joint 3, and connecting parts. The transfer platform track joint 1 is provided with a first inclined surface; the two 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 parts are detachably fixed to the transfer platform track joint 1, the track connector body 2, and the coke oven area track joint 3, so that the first inclined surface corresponds to and is parallel to the second inclined surface, forming a first inclined seam between the first and second inclined surfaces; the third inclined surface corresponds to and is parallel to the fourth inclined surface, forming a second inclined seam between the third and fourth inclined surfaces. By setting the inclined surfaces to meet and form an inclined seam structure, the traditional track connection method (straight-line joint connection method) is changed. When the vehicle wheel passes over it, compared with the traditional track joint form, this inclined seam design changes the contact method between the wheel and the track joint, changing from line contact to near-point contact, which is more conducive to achieving a smooth transition of the vehicle passing 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 vehicle. Meanwhile, the detachable connection method meets the requirement of flexible disassembly and assembly of the track connection when the five pairs of spare vehicles are being transported.
[0026] In a preferred embodiment, a first vertical surface and a second vertical surface are respectively provided at both ends of the first inclined surface, and a third vertical surface and a fourth vertical surface are respectively provided at both ends of the second inclined surface. The first vertical surface and the third vertical surface are corresponding and parallel to each other, and the second vertical surface and the fourth vertical surface are corresponding and parallel to each other. The corresponding parallel vertical surface structure at both ends of the inclined surface serves two purposes. First, it provides positioning and guidance for the inclined surface. When installing the track connector, it makes the docking of the track joint 1 and the track connector body 2 more accurate and faster, improving installation efficiency and accuracy. Second, this structure enhances the stability of the joint. When the vehicle travels on the track, the vertical surface can withstand some of the lateral and longitudinal forces from the vehicle, preventing unnecessary displacement or misalignment of the track joint under the action of the vehicle, further ensuring the reliability and stability of the track connection.
[0027] In a preferred scheme of the embodiment, the two ends of the third inclined surface are provided with a fifth vertical surface and a sixth vertical surface, the two ends of the fourth inclined surface are provided with a seventh vertical surface and an eighth vertical surface, the fifth vertical surface is arranged in correspondence with and parallel to the seventh vertical surface, and the sixth vertical surface is arranged in correspondence with and parallel to the eighth vertical surface, so that quick and accurate positioning can be achieved, and the installation and debugging of components are facilitated. 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, avoid affecting the driving safety due to the loosening or misalignment of the joint during long-term use, and further improve the reliability and robustness of the entire track system.
[0028] In a preferred scheme of the embodiment, the second inclined surface and the third inclined surface are symmetrically arranged about the center plane of the track connector body 2, so that the track connector body 2 has better balance and symmetry when connected to the track joints at both ends. From the perspective of mechanics, when the vehicle drives through the track, the force from the two sides of the track and the vehicle acting on the track connector can be more evenly distributed, avoiding local excessive wear or stress concentration due to uneven force. Thus, the service life of the track connector is improved, the consistency and stability of the track connection performance are ensured, and more reliable support is provided for the smooth operation of the vehicle.
[0029] In a preferred scheme of the embodiment, the connecting piece 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. The connecting plate 4 is sequentially provided with a plurality of first through holes, a plurality of second through holes, and a plurality of third through holes. The first connecting bolt 9 is used to pass through the first through hole, the transfer platform track joint 1 is connected with the first connecting nut by screw threads, and the two connecting plates 4 are fixed on both sides of the transfer platform track joint 1. The second connecting bolt 7 is used to pass through the second through hole, the track connector body 2 is connected with the second connecting nut by screw threads, and the two connecting plates 4 are fixed on both sides of the track connector body 2. The third connecting bolt 8 is used to pass through the third through hole, the coke oven area track joint 3 is connected with the third connecting nut by screw threads, and the two connecting plates 4 are fixed on both sides of the coke oven area track joint 3. The plurality of bolts, nuts, and connecting plates 4 with corresponding through holes cooperate to achieve firm and detachable connection between components. This connection method not only facilitates the installation and disassembly of the track connector body 2 on site, but also quickly meets the needs of the transfer platform 5 for moving and transporting standby vehicles. Moreover, through the fixation from both sides by a plurality of bolts and nuts, the stability and reliability of the connection can be effectively improved, so that the track connection part is not prone to loosening and disconnection under the working conditions of frequent vehicle operation and vibration impact, and the safe operation of the entire track system is ensured.
[0030] In one preferred scheme of the embodiment, the number of first connecting bolts is two, the number of second connecting bolts is two, the number of third connecting bolts is two, the number of first through holes on one connecting plate 4 is two, the number of second through holes is two, and the number of third through holes is two. The specific setting of the number of connecting bolts and through holes on the connecting plate 4 optimizes the connection structure and strength. The arrangement of two bolts can ensure the stability of the connection while avoiding excessive bolts to increase the complexity and cost of assembly. At the same time, the appropriate distribution of the number of bolts can evenly distribute the fastening force on each part of the track connection, prevent the joint from loosening due to insufficient local fastening force, or cause track deformation due to excessive local fastening force, and thus ensure the long-term stable and reliable operation of the entire track connection system.
