Description

Automatic detection mechanism for cable plugging belt of interlocking armored submersible pump

Technical Field

The utility model relates to a chain armor submersible pump cable production technical field, concretely relates to chain armor submersible pump cable blocks up takes automatic checkout mechanism.

Background

At present, cable manufacturers at home and abroad wind the surfaces of three parallel cables by using metal belts in the production process of a chain armored submersible pump cable, and meanwhile, a tractor pulls the cables, so that a spiral armored layer is formed on the surfaces of the cables. After the metal band spirally winds the cable, the cable is pre-pressed by a group of front pressing rollers and pressed into a specified size by a group of rear pressing rollers. In the process of interlocking armor, the strap is with the surface of spiral winding at the cable to the ring is detained mutually, when the strap that is twined appears tripping, the strap can't be drawn away by the tractor by the cable, so at a set of preceding compression roller entrance of pre-compaction, appear in same position repeated winding, the diameter is bigger and bigger, produce and pile up, because the drawing of tractor this moment, accumulational strap can't pass through the certain preceding compression roller in interval along with the cable, it is crowded tighter and tighter to become, the cable is finally locked, lead to the cable to be attenuated, even by breaking. As the armoring is carried out at high speed, when an operator finds a belt blockage and then emergently stops the machine, the operator often has no time to repair the belt, so that the loss which cannot be repaired is caused, and the improvement is needed urgently.

The specific implementation mode is as follows:

the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and fig. 2, the following technical solutions are adopted in the present embodiment: the device comprises a front prepressing roll 1, a bracket 2, a rear finishing press roll 3 and a frame 11; two front prepressing rollers 1 which are symmetrical up and down are respectively screwed on an upper bracket 2 and a lower bracket 2 by utilizing bearings (each bracket 2 is composed of bracket plates which are symmetrically arranged front and back), the other bolt components of the brackets 2 are fixed on the inlet end of a frame 11, and the outlet end of the frame 11 is screwed with a rear finishing roller 3 in an up and down symmetrical way; the chain wheel mechanism also comprises a first chain wheel 4, a chain 5, a second chain wheel 6, a copper sleeve 7, a driven shaft 8, an encoder bracket 9 and an encoder 10; the outer diameter of a first chain wheel 4 is larger than that of a second chain wheel 6, the first chain wheel 4 is fixed at one end of a front prepressing roller 1 below, the first chain wheel 4 is in transmission connection with the second chain wheel 6 through a chain 5, the second chain wheel 6 is fixed on a driven shaft 8, the driven shaft 8 is screwed on and fixed on a support 2 below through a copper sleeve 7 (the driven shaft 8 and the copper sleeve 7 are screwed through a bearing, the copper sleeve 7 and the support 2 are fixedly connected in an inserting mode), the other end of the driven shaft 8 is connected with an encoder 10, the encoder 10 is fixed at the back of the support 2 below through an encoder support 9, and the encoder 10 is connected with an external controller.

The utility model discloses a theory of operation: in the production process of the interlocking armored submersible pump cable, three parallel cables 12 are wound and armored by using a metal belt 13, meanwhile, a tractor pulls the cables 12, and a spiral interlocking armor layer covers the surfaces of the three parallel cables 12;

in the traction process, the first chain wheel 4 fixed on the lower front prepressing roller 1 rotates along with the backward movement of the armored and drawn cable, the cable moves roughly, the rotation speed of the front prepressing roller 1 is slow, namely the rotation speed of the first chain wheel 4 is slow, the cable moves fast, the rotation speed of the front prepressing roller 1 is fast, namely the rotation speed of the first chain wheel 4, and the circumference of the front prepressing roller 1 is fixed and unchanged, so the rotation number of the first chain wheel 4 and the cable moving distance are in a direct proportion relation, namely the circumference of the front prepressing roller is multiplied by the rotation number = the cable moving distance; the condition is transmitted to a second chain wheel 6 through a first chain wheel 4 and a chain 5 and then transmitted to an encoder 10, the revolution number of the encoder 10 is transmitted to an external control end, and when the revolution number received by the control end meets the condition, the normal armoring process is performed; on the contrary, in the armoring process, when the chain armoring layer after passing through the front prepressing roller 1 is tripped, the wound metal belt 13 cannot be drawn away along with the cable 12, so that repeated winding is generated at the inlet of the front prepressing roller 1, further accumulation is generated, the accumulated layer cannot pass through the gap between the pair of the front prepressing rollers 1 arranged up and down, the front prepressing roller 1 rotates slowly until the front prepressing roller stops rotating, at the moment, the rotation number of the encoder 10 cannot meet the rotation number in the above conditions, the external electric control end immediately stops operating, the cable damage caused by belt blocking is avoided, the problem that an operator cannot find the belt blocking in time is solved, and the economic loss caused by a manufacturer is avoided.

After adopting above-mentioned structure, this embodiment's beneficial effect is as follows: this embodiment provides a chain armor submersible pump cable blocks up area automatic checkout mechanism, through the direct ratio relation between the distance that the gyration number of preceding precompression roller and finished cable moved, transmit the gyration number for the encoder through the sprocket chain, the gyration number that the rethread external control ware received the satisfied condition, when the gyration number received can not satisfy the direct ratio condition, then shut down immediately, avoided causing the destruction of cable because of stifled area, the problem that the operator can't discover immediately and block up the area has been solved, avoid the manufacturer to cause economic loss.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
