图2是本发明一个安全联锁装置实施例中的过渡分段绝缘装置和安全控制装置的结构示意图。Fig. 2 is a structural schematic diagram of the transition segment insulation device and the safety control device in an embodiment of the safety interlock device of the present invention.

如图1或2所示,本发明的移动式接触网安全联锁装置中的过渡分段绝缘装置20由两侧汇流排21及其相向端端部之间的合成绝缘子22组成,呈现“Z”型结构;所述过渡分段绝缘装置20安装在轨道正上方,位于两段移动式接触网10之间。As shown in Fig. 1 or 2, the transition segment insulation device 20 in the mobile catenary safety interlock device of the present invention is composed of bus bars 21 on both sides and composite insulators 22 between the opposite ends thereof, presenting a "Z ” type structure; the transition section insulation device 20 is installed directly above the track, and is located between two sections of the mobile catenary 10 .

进一步地,由于某股道上的两段移动式接触网的位置固定,因此其间的“Z”型结构过渡分段绝缘装置也可以固定安装在两段移动式接触网之间并位于轨道正上方,固定安装的方式可以是从厂房顶部吊装或其它固定安装方式。Furthermore, since the positions of the two sections of mobile catenary on a certain track are fixed, the "Z" structure transition section insulation device in between can also be fixedly installed between the two sections of mobile catenary and located directly above the track, The fixed installation method can be hoisting from the top of the factory building or other fixed installation methods.

由于轨道车检修调试现场需要借助起重机等辅助设备,固定安装的过渡分段绝缘装置不可避免地会对辅助设备的作业过程产生干扰。因此,进一步地,过渡分段绝缘装置20的位置非固定,可以安装在伸缩式机构的一端,伸缩式机构的另一端固定在轨道一侧的立柱上;工作时,伸缩式机构伸开将所述过渡分段绝缘装置20移动至轨道正上方的两段移动式接触网10之间;不工作时,伸缩式机构收缩,过渡分段绝缘装置离开轨道正上方,便于检修辅助设备正常作业。Since auxiliary equipment such as cranes are needed for rail vehicle maintenance and commissioning, the fixedly installed transition section insulation device will inevitably interfere with the operation process of auxiliary equipment. Therefore, further, the position of the transition segment insulation device 20 is not fixed, and can be installed on one end of the telescopic mechanism, and the other end of the telescopic mechanism is fixed on the column on one side of the track; The transition section insulation device 20 moves between the two sections of the mobile catenary 10 directly above the track; when not working, the telescopic mechanism shrinks, and the transition section insulation device leaves the top of the track to facilitate the normal operation of the maintenance auxiliary equipment.

如图1或2所示,过渡分段绝缘装置两侧汇流排21的两外端均具有与移动式接触网汇流排13的重叠区域14,所述汇流排重叠区域14的长度小于过渡分段绝缘装置单侧汇流排21的长度。As shown in Figure 1 or 2, the two outer ends of the busbars 21 on both sides of the transition segment insulation device have an overlapping area 14 with the mobile catenary bus bar 13, and the length of the bus bar overlapping area 14 is shorter than that of the transition segment The length of the bus bar 21 on one side of the insulation device.

如图2所示,本发明提供的移动式接触网安全联锁装置,其中的安全控制装置30包括外部撞块31和组合模块32,所述组合模块32包括电磁锁模块327、内部撞块321和326、行程开关、复位弹簧323、电绝缘层325和328;当移动式接触网10摆出到位或超限时,外部撞块31撞击挤压电磁锁模块327,电磁锁模块327和内部撞块产生横向移动,内部撞块撞击到位行程开关滚轮,行程开关被触发,电气联锁控制系统相应给出摆出到位或超限信号。As shown in Figure 2, in the mobile catenary safety interlocking device provided by the present invention, the safety control device 30 includes an external collision block 31 and a combined module 32, and the combined module 32 includes an electromagnetic lock module 327, an internal collision block 321 And 326, travel switch, back-moving spring 323, electrical insulation layer 325 and 328; When the mobile catenary 10 was put in place or exceeded, the external bumper 31 impacted and extruded the electromagnetic lock module 327, the electromagnetic lock module 327 and the inner bumper Lateral movement occurs, the internal bumper hits the roller of the travel switch in place, the travel switch is triggered, and the electrical interlock control system gives a corresponding signal of swing out in place or overrun.

进一步地,组合模块32中的行程开关包括到位行程开关322和超限行程开关324。Further, the travel switch in the combination module 32 includes a travel switch 322 in place and a travel switch 324 beyond the limit.

如图1或2所示,根据本发明的移动式接触网安全联锁装置,其中的安全控制装置30位于汇流排重叠区域14,其中,所述外部撞块31通过焊接、螺栓连接或其它连接方式固定安装在移动式接触网汇流排11的末端上侧,所述组合模块32通过焊接、栓接方式或其它连接方式固定安装在所述过渡分段绝缘装置20两侧汇流排21的末端下侧。外部撞块31和组合撞块32位于相应汇流排的末端,至于在汇流排末端上侧还是下侧的安装位置可以不做限定,因为外部撞块31和组合撞块32的安装位置并不妨碍轨道交通车上受电弓与接触线的正常滑动接触。摆出到位:当移动式接触网10的摆臂11连同其间的汇流排13在摆出过程(0-90°)中,位于汇流排13末端的外部撞块31,通过挤压位于过渡分段绝缘装置汇流排21末端的组合模块32中的电磁锁模块327,使电磁锁模块327和内部撞块321产生横向移动,当内部撞块321在横向移动过程中撞击到到位行程开关322的滚轮时,到位行程开关322被触发,表示该段移动式接触网摆出到位(90°),同时给电气联锁控制系统一个摆出到位信号,此时电磁锁模块327通电工作,其产生的强大吸力紧紧吸住移动式接触网汇流排末端的外部撞块31,从而使移动式接触网与过渡分段绝缘装置锁紧。锁紧后,工作人员看到电气联锁控制系统给出的摆出到位信号,操作隔离开关给摆出到位的移动式接触网进行送电作业。As shown in Figure 1 or 2, according to the mobile catenary safety interlocking device of the present invention, the safety control device 30 is located in the overlapping area 14 of the busbar, wherein the external collision block 31 is connected by welding, bolting or other Fixedly installed on the upper side of the end of the mobile catenary busbar 11, the combined module 32 is fixedly installed under the ends of the busbar 21 on both sides of the transition section insulation device 20 by welding, bolting or other connection methods side. The outer bumper 31 and the combination bumper 32 are located at the end of the corresponding bus bar. As for the installation position on the upper side or the lower side of the bus end, there is no limit, because the installation position of the outer bumper 31 and the combined bumper 32 does not hinder The normal sliding contact between the pantograph and the contact wire on the rail transit vehicle. Swing out in place: When the swing arm 11 of the mobile catenary 10 together with the bus bar 13 in between is in the swing out process (0-90°), the outer bumper 31 at the end of the bus bar 13 is located at the transition section by extrusion The electromagnetic lock module 327 in the combined module 32 at the end of the bus bar 21 of the insulating device causes the electromagnetic lock module 327 and the internal collision block 321 to move laterally. When the internal collision block 321 hits the roller of the limit switch 322 during the lateral movement , the in-position travel switch 322 is triggered, indicating that the section of the mobile catenary is in place (90°), and at the same time, a signal is sent to the electrical interlock control system. At this time, the electromagnetic lock module 327 is powered on, and the strong suction generated by it Tightly suck the external striker 31 at the end of the mobile catenary busbar, so that the mobile catenary and the transition section insulation device are locked. After locking, the staff sees the swing out signal given by the electrical interlock control system, and operates the isolating switch to carry out the power transmission operation to the swing out mobile catenary.

摆出超限:当检测移动接触网到位的行程开关(图中未标示)发生故障时,或者由于人为误操作,导致接触网摆臂继续摆动,其末端的外部撞块31会继续挤压过渡分段绝缘装置尾端的电磁锁模块327,使内部撞块326产生横向移动,进而撞击超限行程开关324的滚轮,超限行程开关324被触发,表示该段移动式接触网的摆臂越过安全的工作位置,摆出超限,此时给电气联锁控制系统一个超限信号,此时隔离开关无法操作,不能进行送电作业。Swing out of limit: When the limit switch (not shown in the figure) that detects the position of the mobile catenary fails, or due to human misoperation, the swing arm of the catenary continues to swing, and the external impact block 31 at the end will continue to squeeze the transition The electromagnetic lock module 327 at the tail end of the section insulation device causes the internal collision block 326 to move laterally, and then hits the roller of the over-limit travel switch 324, and the over-limit travel switch 324 is triggered, indicating that the swing arm of this section of the mobile catenary has crossed the safety zone. When the working position is set out of limit, an over-limit signal is given to the electrical interlock control system. At this time, the isolating switch cannot be operated and the power transmission operation cannot be performed.

进一步地,当超限行程开关324触发后,表示移动式接触网摆出超限,此时自动报警装置40(图中未示出)进行声光报警,提醒现场操作人员出现接触网超限问题,引起作业人员注意并进行紧急处理。自动报警装置的位置可根据现场需要设置,可以位于隔离开关附近,自动报警装置40工作说明超限,则隔离开关此时无法操作,不能进行送电作业。Further, when the over-limit stroke switch 324 is triggered, it means that the mobile catenary swings out of the limit.
