[0002] In the prior art, the circuit breaker carrying trolley is generally installed on the circuit breaker as an accessory of the circuit breaker. At this time, the circuit breaker and the trolley are fixedly connected by bolts. In this case, the circuit breaker and the trolley are not easy to separate; or The circuit breaker and the trolley are connected and separated by the cooperation of the turntable and the worm. In this case, the power to operate the device is decomposed, so that the operation efficiency is low

Embodiment Construction
[0018] Preferred embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Through the accompanying drawings and corresponding descriptions, those skilled in the art will understand the features and advantages of this aspect.
[0019] figure 1 It is a schematic diagram of the combination of the circuit breaker 3 and the circuit breaker trolley 1. Circuit breaker 3 can be in the test position ( figure 1 ) and the working position. Such as figure 1 As shown, the circuit breaker 3 may comprise a floor 31 in which an opening 32 may be provided. The bottom of the circuit breaker 3 may be provided with an opening (not shown), which may be used to accommodate a driving protrusion (such as image 3 shown and will be described in detail below). The trolley can be fixedly installed on a switch cabinet (not shown), and installed together with the circuit breaker 3 from below the circuit breaker 3 . The trolley can...

The invention relates to a device for automatically separating a circuit breaker from a trolley and combining the circuit breaker with the trolley. The device comprises a lead screw, a lead screw fixing bracket, a driving block and a guide device, wherein the lead screw fixing bracket is fixedly installed relative to a trolley main body for supporting the lead screw; the lead screw has a first end part and a handle insertion hole is formed in the first end part; the driving block sleeves the lead screw and is internally provided with a thread which is used for being joined with the lead screw; a driving bump for penetrating through an elongated slot which is formed in the top of the trolley and being joined in an opening in the bottom of the circuit breaker for combining the circuit breaker with the trolley is arranged on the driving block so as to drive the circuit breaker to move between a test position and a work position; the guide device is used for enabling the driving block to move between a combining position and a separating position when being connected with the driving block, the combining position corresponds to the position of the driving block when the circuit breaker is combined with the trolley, and the separating position corresponds to the position of the driving block when the circuit breaker is separated from the trolley. The invention further relates to a method for operating the device.
Description
technical field [0001] The invention relates to a disengagement-combination device, in particular to a device for automatically disengaging and combining a circuit breaker and a trolley, as well as a method of using the device. Background technique [0002] In the prior art, the circuit breaker carrying trolley is generally installed on the circuit breaker as an accessory of the circuit breaker. At this time, the circuit breaker and the trolley are fixedly connected by bolts. In this case, the circuit breaker and the trolley are not easy to separate; or The circuit breaker and the trolley are connected and separated by the cooperation of the turntable and the worm. In this case, the power to operate the device is decomposed, so that the operation efficiency is low. Contents of the invention [0003] The invention provides a device for automatically separating and combining a circuit breaker and a trolley, comprising: a screw rod; a screw fixing bracket fixedly installed re...
