Embodiment

[0058] This embodiment provides a long-stroke heavy drag chain running device, such as figure 1 with 2 As shown, it is suitable for supporting and driving the drag chain 3 to reciprocate. The drag chain 3 includes an upper segment 31 of the drag chain, a steering ring segment 33 of the drag chain and a lower segment 32 of the drag chain, and the long-stroke heavy drag chain running device includes guide rails 1, Supporting wheel support 2 and driving mechanism.

[0059] Rail 1, such as Figure 13 As shown, it includes a first guide groove 11 for the rolling fit of the first support roller 21 and a second guide groove 12 for the rolling fit of the third support roller 29 .

[0060] The support roller bracket 2 is arranged between the upper section 31 of the drag chain and the lower section 32 of the drag chain, and includes a support roller assembly, a connecting rod 25 , a third support roller 29 and a fourth support roller 63 .

[0061] Such as Figure 4-6 As shown, the ...

Abstract

The invention provides a long-stroke heavy drag chain operating device. The long-stroke heavy drag chain operating device comprises a guide rail and a supporting roller bracket. The supporting rollerbracket is arranged between an upper drag chain segment and a lower drag chain segment and is provided with first supporting rollers matched with the guide rail and second supporting rollers suitablefor supporting the upper drag chain segment. As the upper drag chain segment is in rolling connection to the second supporting rollers, compared with the prior art, the friction force between the supporting roller bracket and the upper drag chain segment is reduced, so that on the one hand, the supporting roller bracket is unlikely to deform, conditions that a drag chain is derailed and a drag chain body is damaged are prevented effectively, the service life is prolonged and the maintenance and replacement costs are lowered, and on the other hand, the driving force for drag chain operation isreduced.

Description

technical field [0001] The invention relates to the technical field of towlines, in particular to a long-stroke heavy-duty towline running device. Background technique [0002] Drag chains are suitable for reciprocating motions and are widely used in the fields of automation equipment such as CNC machine tools, robotic arms, lifting and transportation equipment, and automated warehouses. They can pull and protect built-in cables, oil pipes, air pipes, and water pipes. [0003] The towline is formed by splicing several chain links. The long-distance heavy-duty towline is generally two to three hundred meters or longer. The towline can be divided into three parts during the movement: the lower section of the towline, the steering ring section of the towline and the upper section of the towline , the lower section of the towline is laid flat on the support frame of the towline, the upper section of the towline is stacked on the top of the lower section of the towline due to lon...
