The plastic cable spool comprises a take-up
wheel main body, a ratchet wheel, a sector gear and a pullback spring, wherein
the sector gear is composed of a circumferential part and a tooth shaped part,
the ratchet wheel is rotatable fixed on the take-up wheel main body, and its
spring fixing end is separately connected with one end of two pull back
springs. In the take-up state, the two pull back springs are symmetrically
arranged with respect to the spring fixing end of the ratchet wheel.
During the construction process, the laying
of plastic cable spool cannot be fully mechanized, and the manual operation is
heavy. In addition, most cables use VV35mm2, VV50mm2 or even VV70mm2. This
large diameter power plastic cable spool is coiled on a disc when leaving the
factory, which cannot be moved by manpower. It can only be manually removed on
the ground and pulled through the pipe by manpower. In order to keep consistent
with the pace of wire head traction, a certain length of plastic wire reel should
be removed from the reel before the traction work starts, and several
construction personnel should monitor the setting out.
Do the following
steps to improve quality:
1. Statistical quality control stage of
cable spool.
The characteristic of this stage is to use
the statistical principle to carry out quality control between production
processes, prevent nonconformities and inspect the quality of products. In
terms of mode, the responsible person is also transferred from full-time
inspection personnel to professional quality control engineers and technicians.
2. Cable spool quality inspection stage.
The control box shall be strictly inspected
to ensure the quality of products transferred to the next process and
delivered. The characteristics of full-time inspection are "separation of
three powers", that is, standards are formulated; someone is responsible
for manufacturing; There are full-time personnel to inspect the quality of
products. The essence of this practice is to divide waste products into different
grades. Although this has a certain effect on the factory quality
The payoff reel is made of steel plate,
reinforcement and channel steel (the blanking size is determined by itself).
Its structural design is as follows: channel steel is symmetrically placed into
a circle as the bottom fixed support foot, and two steel plates are used to
make a rotary disc. The upper part is a rotary disc surface, the lower part is
a fixed disc surface. The fixed disc surface is welded to the channel steel
surface, and a steel bar is used to make a central rod. One end of the thread
can be screwed into the central bearing screw opening of the rotary disc, one
end is made into a ring buckle to facilitate the lifting of mechanical
equipment.
The equipment is simple in structure,
reasonable in design and convenient in handling, which not only solves many
problems mentioned above, but also enables the paying off operation to realize
semi mechanized operation. More importantly, due to its small and flexible
size, the payoff reel can be placed near the laying pipe orifice, and the
traction wire head can directly enter the pipe.
