Description

Technical Field

[0001] The utility model relates to the technical field of lifting and supporting tools, in particular to an electric lifting and supporting trolley for a circuit breaker. Background Art

[0002] When installing circuit breakers into a cabinet, their weight makes handling them inconvenient and dangerous. Therefore, manufacturers with frequent assembly operations often design electric lift trolleys that can transport and lift circuit breakers of various models and specifications over short distances for easy installation. These electric lift trolleys typically use a crane (or manual labor) to lift the circuit breaker onto a transfer trolley (the trolley's plane is parallel to the cabinet's circuit breaker placement surface). The trolley is then pushed into the cabinet. This method is time-consuming, labor-intensive, and unsafe, making it prone to accidents such as circuit breakers falling. Utility Model Content

A linear bearing 61 is provided in a slide cylinder 62 for being sleeved on the sliding shaft 4. A locking pin plate 7 is also provided on the support plate 6 to limit the movement of the support plate 6 relative to the sliding shaft 4.

[0017] As a further configuration of the above solution, the lifting platform 3 is further provided with a first crossbeam 51 and a second crossbeam 52 , the first crossbeam 51 is provided with a pin plate slide groove 54 , and the second crossbeam 52 is provided with a pin plate shift groove 55 .

[0018] As a further arrangement of the above scheme, the locking pin plate 7 includes a latch plate 70, a mounting plate 71, a tension spring 72, a hinged rod 73, a distance adjustment handle 74 and a reset tension spring 75. The latch plate 70 passes through the mounting plate 71, and its two ends are respectively aligned with the pin plate slide groove 54 and the pin plate gear groove 55 for insertion.

[0019] As a further configuration of the above solution, the two ends of the tension spring 72 are respectively connected and fixed to the latch plate 70 and the mounting plate 71 , and based on the elastic restoring force, the latch plate 70 is pulled relative to the second beam 52 to move the latch plate gear slot 55 .

[0020] As a further configuration of the above solution, a waist-shaped groove 53 is further provided on the second crossbeam 52 , and a slider 63 is provided on the supporting plate 6 to slide in the waist-shaped groove 53 .

[0021] As a further configuration of the above scheme, the mobile seat 1 is provided with a battery compartment 11, a mobile bracket 12, a sliding wheel 13 and a universal wheel assembly with a brake device. The universal wheel assembly is arranged on the side of the battery compartment 11. A control panel 21 and a switch button 22 connected to the battery compartment 11 are provided on the support frame 2. A power unit for lifting and lowering the platform 3 is also provided in the support frame 2.

[0022] The utility model of the circuit breaker electric lifting trolley, such as Figure 1-4 As shown, the trolley of this embodiment includes a lifting platform 3 for lifting the circuit breaker.
