Abstract
The utility model provides a structure equal to a double pole disconnecting switch in a tunnel. A single pole disconnecting switch I of the structure equal to the double pole disconnecting switch is connected to a master operation mechanism through a driving connecting lever, a transmission rod, and a mechanism rocking arm assembly in sequence to form one single pole disconnecting switch. The structure also includes a single pole disconnecting switch II and a slave operation mechanism. The single pole disconnecting switch II is connected with the slave operation mechanism through the driving connecting lever, the transmission rod, the mechanism rocking arm assembly in sequence to form anther single pole disconnecting switch. A contact point of a contactor of a control loop of the master operation mechanism and a contact point of a connector of a control loop of the slave operation mechanism are in serial connection, so as to enable synchronization motion of the master operation mechanism and the slave operation mechanism, to drive the single pole disconnecting switch I and the single pole disconnecting switch II at the same time. The structure which is simple, and high in stability when being mounted in the tunnel, low in production cost, and short in production period, fulfills a function of mounting a double pole disconnecting switch in a tunnel, has no safety hidden trouble, and achieves standardized production for each component.
Description
Technical field
The utility model relates to the structure that is equivalent to bipolar isolation switch in a kind of tunnel.
Background technology
Tunnel is a kind of common building in railway construction engineering, and shape is rendered as semicircle more.Because the design requirement of railway contact line specialty, often can be by driving connecting lever on the arc wall in tunnel, the bipolar isolation switch 1 that drive link and mechanism's rocker arm assembly installing contact net are used, due to narrow space in tunnel, and the weight of bipolar isolation switch is large, the space that overall dimension takies is many, so while bipolar isolation switch being installed in the tunnel wall in reserved isolating switch installation cave, not only cannot guarantee the traffic space of train, the safe insulation of isolating switch is apart from waiting all technical, and bipolar isolation switch has taken too much rescue passage with motor-operating mechanism 2, its mounting means has also affected the resistance to overturning of isolating switch, these problems are used all to the operation in later stage and have been left very large potential safety hazard.As shown in Figure 1.Therefore we need a kind of form that is equivalent to bipolar isolation switch to meet the requirement that bipolar isolation switch is installed in tunnel.
Summary of the invention
The object that the utility model is is to provide the structure that is equivalent to bipolar isolation switch in a kind of tunnel, is beneficial in tunnel, reasonably arrange bipolar isolation switch, not only will realize the function of bipolar isolation switch, and will meet every safety standard.
For achieving the above object, the technical solution adopted in the utility model is to provide the structure that is equivalent to bipolar isolation switch in a kind of tunnel, wherein: this structure that is equivalent to bipolar isolation switch includes single-pole isolator ⅠHe active operation mechanism, described single-pole isolator I is successively by driving connecting lever, drive link to be connected with active operation mechanism with mechanism rocker arm assembly, and a single-pole isolator of formation; Also include single-pole isolator ⅡHe slave operation mechanism, described single-pole isolator II is successively by driving connecting lever, drive link to be connected with slave operation mechanism with mechanism rocker arm assembly, and another single-pole isolator of formation; The control loop of described active operation mechanism is connected with the contacts of contactor of the control loop of slave operation mechanism, can make active operation mechanism and slave operation mechanism synchronization action, drives single-stage isolated switch and single-pole isolator II simultaneously.
Effect of the present utility model is that the bipolar isolation switch of installing in tunnel is simple in structure, and stability is high, has met the function that bipolar isolation switch is installed in tunnel, and there is not potential safety hazard, each part-subassemble standardization is produced, and design cost and low cost of manufacture are with short production cycle etc.

Embodiment
To being equivalent to the structure of bipolar isolation switch in tunnel of the present utility model, be illustrated by reference to the accompanying drawings.
The structure collectivity that is equivalent to bipolar isolation switch in tunnel of the present utility model is that the installation form of installing with two single-pole isolators embodies, and active operation mechanism 5 is responsible for receiving the divide-shut brake instruction that control desk sends; Slave operation mechanism 6 follows active operation mechanism 5 and moves together, and these two operating mechanisms all have independently divide-shut brake signal and fault-signal, when operation, only need 5 one divide-shut brake signals to active operation mechanism, just can guarantee that these two isolating switches carry out divide-shut brake action simultaneously, have met the specification requirement of bipolar isolation switch.
In the tunnel of utility model of the present utility model, be equivalent to the structure of bipolar isolation switch as shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the bipolar isolation switch 1 of installing in original tunnel is resolved into single-pole isolator I 3 and the rear partial installation of single-pole isolator II 4, single-pole isolator I 3 is joined active operation mechanism 5, and single-pole isolator II 4 is joined slave operation mechanism 6.
The object of said structure is that the shared bulk of bipolar isolation switch 1 is larger; often can invade the traffic space of train or can not guarantee safe insulation distance; and the shared bulk of single-pole isolator I 3 and single-pole isolator II 4 is very little, can meet every installation requirement that isolating switch is installed in tunnel.Active operation mechanism 5 and slave operation mechanism 6 are interrelated by electrical connection, and all main button or knobs of making are arranged in active operation mechanism 5, and the control loop of slave operation mechanism 6 is connected with the contacts of contactor of the control loop of active operation mechanism 5.When active operation mechanism 5 receives the divide-shut brake instruction that effector sends, slave operation mechanism 6 can follow active operation mechanism 5 and move together, drive single-pole isolator I 3 and single-pole isolator II 4 simultaneously, guarantee that these two isolating switches synchronously carry out divide-shut brake action, have realized the function of bipolar isolation switch.In addition, active operation mechanism 5 and slave operation mechanism 6 all have independently opening and closing state signal and fault diagnosis signal, so just can monitor very accurately the state of single-pole isolator I 3 and single-pole isolator II 4 each time domains, avoid the generation of accident.
