In a preferred embodiment: the swing rod is rotatably pivoted on the frame.

In a preferred embodiment: the two swing rods are symmetrically arranged.

In a preferred embodiment: the outer end of the connecting rod is rotatably pivoted with the outer end of the oscillating rod, and the inner end of the connecting rod and the inner end of the oscillating rod are rotatably and slidably arranged in the groove.

In a preferred embodiment: the bicycle frame is characterized by further comprising an elastic piece, the elastic piece is tensioned between the bicycle frame and the swing rod, and the swing rod is driven to extend out of the groove by the elastic force of the elastic piece.

In a preferred embodiment: the elastic element is a torsion spring and is connected to the position where the swing rod is pivoted with the frame.

In a preferred embodiment: the groove is provided with an upper top surface and a lower bottom surface, and the lower bottom surface of the groove corresponds to the auxiliary roller and is provided with a abdicating notch.

In a preferred embodiment: and traveling wheels are respectively arranged at the positions of four corners at the bottom of the frame.

In a preferred embodiment: the auxiliary idler wheel is arranged on the rotating seat, and the rotating seat can be connected with the oscillating bar in a circumferential rotating mode.

In a preferred embodiment: the walking wheel is arranged on the rotating seat, and the rotating seat can be connected with the frame in a circumferential rotating mode.

Compared with the background technology, the technical scheme has the following advantages:

when the trolley is pushed to transport, the swing rod extends outwards, the rolling auxiliary roller is arranged in front of the trolley frame, and if the walking wheel is blocked to incline forwards, the rolling auxiliary roller can be grounded to provide front support, so that the service trolley is prevented from turning forwards. When the transfer trolley and the middle-placed cabinet are butted to get the circuit breaker, the swing rod is withdrawn into the groove, and the frame cannot be interfered. Consequently, the pendulum rod that the transportation dolly of this scheme can be opened and fold up through the setting under the condition that does not influence the transportation dolly and put the cabinet butt joint in, rolls and assists the gyro wheel and can provide the protection when the walking, has the advantage of preventing empting.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 shows the three-dimensional schematic view of the transfer trolley for the circuit breaker of the centrally installed switchgear.

Fig. 2 is a schematic top view of the centrally installed switchgear circuit breaker transfer trolley of fig. 1.

Detailed Description

Referring to fig. 1 and 2, the transfer trolley for the circuit breaker of the centrally installed switchgear comprises a frame 10, an object stage 20 arranged at the top of the frame, a handrail 30 arranged above the rear side of the frame, and a traveling wheel 40 arranged at the bottom of the frame, wherein a transversely extending groove 12 is arranged at the lower part of the front side of the frame 10, and the transfer trolley further comprises at least one swing rod 50, the inner end of the swing rod 50 is movably connected in the groove 12, an auxiliary roller 60 is arranged below the outer end of the swing rod 50, the auxiliary roller 60 is slightly higher than the traveling wheel 40, and the auxiliary roller 60 is in a ground-off state when the trolley normally travels. The swing link 50 can be wholly received in the groove 12, or the outer end swings forwards to drive the auxiliary roller 60 to move to the front of the frame 10.

When the middle cabinet is in butt joint, the swing rod 50 can be collected into the groove 12, the swing rod 50 can be pulled out of the groove 12 during normal transportation, the auxiliary roller 60 is slightly higher than the travelling wheel 40, so that the auxiliary roller 60 is suspended during normal travelling, and if the auxiliary roller 60 inclines forwards, the auxiliary roller 60 lands to form support. The auxiliary roller 60 is only slightly higher than the road wheels 40, for example, the auxiliary roller 60 is 1-5 cm from the ground.

Preferably, the inner end of the swing link 50 is rotatably pivoted to the frame 10. Thus, the operation of opening and folding the swing link 50 is more convenient.

Preferably, the two swing rods 50 are symmetrically arranged. In this way, the auxiliary rollers 60 are arranged on the two swing rods 50, so that the supporting points are more, the stress is more uniform during dumping, and the safety performance is better.

It can be understood that the device also comprises a connecting rod, the outer end of the connecting rod is pivoted with the outer end of the swing rod in a rotating mode, and the inner end of the connecting rod and the inner end of the swing rod are rotatably and slidably arranged in the groove. That is, a triangle is enclosed by a connecting rod and a swing rod and the groove of the frame, the auxiliary roller 60 is arranged at the front end point of the triangle, and when the auxiliary roller is not used, the connecting rod and the swing rod are both accommodated in the groove. The structure is stable and convenient to operate.

Preferably, the vehicle body further comprises an elastic member, the elastic member is tensioned between the vehicle frame 10 and the swing link 50, and the elastic force of the elastic member drives the swing link 50 to extend out of the groove 12. When the centrally installed switchgear is butted, the elastic force of the elastic element can be directly overcome, and the swing rod 50 is pressed into the groove 12. After the trolley is separated from the centrally installed switchgear, the elastic piece can push the swing rod 50 open, so that the swing rod 50 is in an open state when the trolley moves. Further preferably, the elastic element is a torsion spring and is connected to a position where the swing rod is pivoted with the frame.

Preferably, the groove 12 has an upper top surface and a lower bottom surface, and the lower bottom surface of the groove is provided with a relief notch corresponding to the auxiliary roller 60. Therefore, the upper side and the lower side of the groove 12 surround the swing rod 50, and the stability is better.

Preferably, the bottom of the frame 10 is provided with road wheels 40 at four corners.

Preferably, the road wheels 40 are arranged on a rotating base which is circumferentially rotatably connected with the frame 10. Thus, the moving direction of the trolley can be easily adjusted when the trolley travels.

Similarly, the auxiliary roller 60 is disposed on the rotating seat, the rotating seat is connected to the swing rod 50 in a circumferential rotating manner, and the auxiliary roller 60 can circumferentially rotate relative to the swing rod 50, so that the flexibility is better.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
