[0032] Embodiment 1

[0033] The existing bipolar telescopic device has a complex structure, occupies a large area in the horizontal direction, and cannot be well arranged in the limited stage space. In addition, the existing bipolar telescopic device cannot achieve the synchronous extension and retraction of the primary and secondary mobile frames, which is limited in use function and cannot meet the use conditions of multiple scenes.

[0034] In view of this, an embodiment of the utility model provides a bipolar synchronous reciprocating telescopic device, including: a chassis 100, a primary movable frame 200 and a secondary movable frame 300, the chassis 100 is fixedly arranged, the primary movable frame 200 is horizontally moved relative to the chassis 100 through a first transmission mechanism, a second transmission mechanism is arranged between the chassis 100, the primary movable frame 200 and the secondary movable frame 300, the second transmission mechanism has a traction circuit 410 and a reset circuit 420 which are independent of each other, the secondary movable frame 300 is pulled out in a horizontal direction relative to the primary movable frame 200 through the traction circuit 410, and the secondary movable frame 300 is reset and retracted in a horizontal direction relative to the primary movable frame 200 through the reset circuit 420.

[0035] The primary mobile frame 200 is horizontally moved relative to the chassis 100 and extended outwards through the first transmission mechanism, and at the same time, the secondary mobile frame 300 is extended outwards relative to the primary mobile frame 200 under the action of the traction circuit 410 of the second transmission mechanism, thereby realizing the synchronous traction extension of the primary mobile frame 200 and the secondary mobile frame 300. The primary mobile frame 200 is horizontally moved inwards relative to the chassis 100 through the first transmission mechanism, and at the same time, the secondary mobile frame 300 is retracted inwards relative to the primary mobile frame 200 under the action of the reset circuit 420 of the second transmission mechanism, thereby realizing the synchronous reset and retraction of the primary mobile frame 200 and the secondary mobile frame 300. It can be seen from the above working process that the bipolar synchronous reciprocating telescopic device can realize the synchronous traction extension and synchronous reset and retraction of the primary mobile frame 200 and the secondary mobile frame 300, and can meet the use under multiple scene conditions. In addition, the bipolar synchronous reciprocating telescopic device has a simple overall structure, occupies little space in the horizontal direction, and can be well arranged in a limited stage space.

[0036] In an optional manner of this embodiment, the first transmission mechanism includes a gear 510 and a rack 520 that mesh with each other, the rack 520 is fixedly disposed on the chassis 100 , and the gear 510 is disposed on the primary moving frame 200 .

[0037] For details, please see Figure 1 The gear 510 is driven to rotate by the reduction motor gear 510 box, the reduction motor gear 510 box is fixedly set on the primary moving frame 200, the gear 510 is meshed with the rack 520, the rack 520 is fixedly set on the chassis 100, and the length of the rack 520 is not less than the telescopic distance of the primary moving frame 200.

[0038] The first transmission mechanism adopts meshing transmission of gear 510 and rack 520, which has simple structure and convenient arrangement, and realizes horizontal movement of primary moving frame 200 relative to chassis 100 to extend outward or retract inward. Of course, the first transmission mechanism can also adopt other transmission modes such as meshing transmission between gears 510, which is not limited here.

[0039] In an optional manner of this embodiment, the second transmission mechanism includes a fixed block 610, a traction steering wheel group, a fixed frame 630 and a traction rope 640. The fixed block 610 is fixedly arranged on the chassis 100, the traction steering wheel group is arranged at both ends of the first-level moving frame 200, the fixed frame 630 is arranged on the second-level moving frame 300, and one end of the traction rope 640 is fixed to the fixed block 610, passes through the traction steering wheel, and the other end is connected to the fixed frame 630.

[0040] See also Figure 1The traction steering wheel group includes a first traction steering wheel 621 arranged at the first end of the primary mobile frame 200 and a second traction steering wheel 622 arranged at the second end of the primary mobile frame 200. The fixed block 610 has a first fixed end 611 and a second fixed end 612 arranged oppositely. The fixed frame 630 has a first extended end 631 and a second extended end 632 arranged oppositely. The first fixed end 611, the first traction steering wheel 621, the first extended end 631 and the traction rope 640 therebetween jointly form a traction loop 410. The second fixed end 612, the second traction steering wheel 622, the second extended end 632 and the traction rope 640 therebetween jointly form a reset loop 420. The fixed frame 630 is fixed to the secondary mobile frame 300 and is located near the middle of the secondary mobile frame 300. The position of the fixed block 610 is adapted to the fixed frame 630, is located below the primary mobile frame 200, and is fixed to the chassis 100.

[0041] See also Figure 2 When the primary moving frame 200 moves to the left under the positive meshing of the gear 510 and the rack 520, the primary moving frame 200 first extends outwards. At the same time, the traction rope 640 between the first traction steering wheel 621 and the first fixed end 611 in the traction circuit 410 becomes longer. Since the total length of the traction rope 640 in the traction circuit 410 remains constant, the fixed frame 630 will be moved to the left relative to the primary moving frame 200 by the force of the traction rope 640, so that the secondary moving frame 300 extends outwards relative to the primary moving frame 200, realizing the synchronous traction and extension of the primary moving frame 200 and the secondary moving frame 300. At this time, the reset circuit 420 only plays a follow-up role and does not have power transmission. Similarly, when the primary moving frame 200 moves to the right under the action of the reverse meshing of the gear 510 and the rack 520, the primary moving frame 200 is first retracted inwards. At the same time, the traction rope 640 between the second traction steering wheel 622 and the second fixed end 612 in the reset circuit 420 becomes longer. Since the total length of the traction rope 640 in the reset circuit 420 remains constant, the fixed frame 630 will be moved to the right relative to the primary moving frame 200 by the force of the traction rope 640, so that the secondary moving frame 300 is retracted inwards relative to the primary moving frame 200, realizing the synchronous reset and retraction of the primary moving frame 200 and the secondary moving frame 300. At this time, the traction circuit 410 only plays a follow-up role and does not have power transmission.

[0042] In an optional manner of this embodiment, the chassis 100 is provided with a plurality of primary load-bearing wheel groups, and the primary mobile frame 200 is connected to the primary load-bearing wheel groups.

The first mobile frame 200 is symmetrically provided with a first main beam, which is an H-shaped steel. The cross section of the first main beam is an open C shape, and the rim surface of the first running wheel 720 fits the C-shaped cross section.

[0045] In an optional manner of this embodiment, the primary mobile frame 200 is provided with a plurality of secondary load-bearing wheel groups, and the secondary mobile frame 300 is connected to the secondary load-bearing wheel groups.
