Abstract
The utility model relates to a drag chain, which comprises two chains arranged in parallel, wherein the chain is formed by connecting a plurality of chain blocks in sequence, the two ends of each chain block are respectively provided with a slot and an insertion part which are mutually matched, and the side wall of each slot is provided with a center pin which runs through the insertion part; a support rod is arranged between the two chains, and a sleeve is rotatably arranged on the outer side of the support rod. The utility model discloses a drag the outside installation sleeve pipe that the chain passes through the support frame, the sleeve pipe is rotatable, and cable, oil pipe etc. that significantly reduce rub with the support frame, and it is complete to protect cable, oil pipe etc., increase of service life, the operation is more safe and reliable.
Description
Technical Field
The utility model relates to a chain technical field especially indicates a drag chain.
Background
The drag chain, also known as a wire and cable protection drag chain, is a device for binding a cable or an electric wire or an air compression pipe and an oil pressure pipe to facilitate the rotation and the movement of the drag chain, is suitable for being used in reciprocating occasions, and can play a role in traction and protection of the built-in cable, oil pipe, air pipe, water pipe and the like. At present, the structure and the function of a common drag chain are simple, when the drag chain is dragged, a support frame of the drag chain often rubs with a cable, an oil pipe and the like inside, so that the cable, the oil pipe and the like are easily worn and broken, oil leakage and electric leakage are caused, and potential safety hazards are easily caused.
Disclosure of Invention
The utility model provides a drag chain to overcome the problem that current structure function is simple can't be to protection such as cable, oil pipe.
The utility model adopts the following technical scheme:
a drag chain comprises two chains arranged in parallel, wherein each chain is formed by sequentially connecting a plurality of chain blocks, two ends of each chain block are respectively provided with a slot and an insertion part which are mutually matched, and the side wall of each slot is provided with a center pin penetrating through the insertion part; a support rod is arranged between the two chains, and a sleeve is rotatably arranged on the outer side of the support rod.
In a further improvement, the sleeve is a steel pipe.
In a further improvement, the two ends of the center pin are connected with covers.
In a further improvement, the outer wall of the sleeve is covered with a soft cushion layer.
From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: the utility model discloses a drag the outside installation sleeve pipe that the chain passes through the support frame, the sleeve pipe is rotatable, and cable, oil pipe etc. that significantly reduce rub with the support frame, and it is complete to protect cable, oil pipe etc., increase of service life, the operation is more safe and reliable.
Drawings
Fig. 1 is a schematic view of a partial three-dimensional structure of a towing chain of the present invention.
Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
Referring to fig. 1, a drag chain comprises two chains 1 arranged in parallel, wherein the chains 1 are formed by sequentially connecting a plurality of chain blocks 10, two ends of each chain block 10 are respectively provided with a slot 102 and an insertion part 101 which are mutually matched, the insertion part 101 of each chain block 10 is inserted into the slot 102 of the adjacent chain block 10, the side wall of each slot 102 is provided with a center pin 2 penetrating through the insertion part 101, two ends of the center pin 2 are connected with covers 21, the two ends of each center pin 2 are buckled by the covers 21 and fixed on the chain blocks 10, a support rod 11 is arranged between the two chains 1, and the outer side of the support rod 11 is rotatably provided with a sleeve 12. The sleeve 12 is a steel pipe, a cushion layer 121 is covered on the outer wall of the sleeve 12, and the cushion layer 121 is made of rubber. When the drag chain pulls the cable, sleeve 12 rotates along with the cable removes on sleeve 12, the friction between the cable that significantly reduces and bracing piece 11, and the protection cable is difficult for brokenly the skin.
The utility model discloses a drag chain 1 through the outside installation sleeve 12 of support frame, sleeve 12 is rotatable, the cable that significantly reduces, oil pipe etc. and support frame friction, and it is complete to protect cable, oil pipe etc. increase of service life, the operation is more safe and reliable.
The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
