Abstract
The special pulley for cable laying in the saddle-shaped well comprises a pulley block and a support, wherein the pulley block is in an arc structure and comprises an arc pulley frame which is parallel to each other and pulleys which are arranged in the arc pulley frame in a sliding way; the support is formed by sequentially connecting an adjustable well edge fixing support, a support adjusting sleeve and a well edge fixing clamp. The utility model discloses make according to cable and cable shaft structure, the assembly pulley presents the arc, accords with the cable atress characteristics, reduces frictional force when laying, low in cost, easy operation, and convenient to use avoids the cable to receive the damage when laying in the pit, practices thrift the manpower, can effectively improve cable laying cable's in the pit work efficiency.
Description
Technical Field
The utility model relates to a can be used for the isolated plant of cabling in the cable shaft, especially relate to the special coaster of cable laying in the shape of a saddle well.
Background
At present when carrying out cable shaft cable laying work in the pit, the mode that adopts the cable directly to lay in the well through the cable shaft to go on usually, this kind of traditional mode makes the unable fixed pulley of circular shape cable well head, can direct contact cable well edge when cable laying transports, increase and pull frictional force, it reaches cable sheath and internal insulation easily to hinder, the artifical degree of difficulty of laying has been strengthened, thereby inconvenience has been caused to the construction, reduce cable laying work efficiency, damage cable insulating properties, also buried the potential safety hazard for the safe operation of cable in the future.
Disclosure of Invention
In order to solve the problem, the utility model provides an can effectually avoid cable sheath and inside damage to reduce the resistance, for improving the special coaster of cable laying in the saddle shape well that efficiency was established in the work of cable laying in the well, its technical scheme as follows:
the special pulley for cable laying in the saddle-shaped well comprises a pulley block and a support, wherein the pulley block is in an arc structure and comprises an arc pulley frame which is parallel to each other and pulleys which are arranged in the arc pulley frame in a sliding way; the support is formed by sequentially connecting an adjustable well edge fixing support, a support adjusting sleeve and a well edge fixing clamp.
Two ends of the arc pulley frame are fixedly arranged on the adjustable well edge fixing support.
The support adjusting sleeve is provided with adjusting holes at intervals.
The adjustable well edge fixing support is provided with assembling holes at two ends, and the assembling holes are movably connected with the support adjusting sleeve through adjusting holes so as to adjust the length of the adjustable well edge fixing support.
The front end of the support adjusting sleeve is provided with a well edge fixing clamp, and the front end of the well edge fixing clamp is provided with a fixing screw in a penetrating mode and used for adjusting the opening and closing distance of the well edge fixing clamp.
The utility model has the advantages of effect: the pulley block is arc-shaped, meets the stress characteristics of the cable, reduces friction force during laying, is low in manufacturing cost, simple to operate and convenient to use, avoids the cable from being damaged during underground laying, saves manpower, and can effectively improve the working efficiency of underground cable laying.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
in the figure, 1 pulley, 2 pulley frames, 3 adjustable well edge fixing supports, 4 support adjusting sleeves, 5 adjusting holes, 6 well edge fixing clamps and 7 fixing screws.
Detailed Description
Example 1
As shown in fig. 1, the saddle-shaped pulley special for cable laying in the well is composed of a pulley 1, a pulley frame 2, an adjustable well edge fixing support 3, a support adjusting sleeve 4, an adjusting hole 5, a well edge fixing clamp 6 and a fixing screw 7; pulley 1 is fixed on pulley frame 2, is furnished with four adjustable well edge fixed bolster 3 on the pulley frame 2, and the support comprises support adjusting sleeve 4, well edge fixation clamp 6, is furnished with regulation hole 5 on the support adjusting sleeve 4, has set screw 7 on the well edge fixation clamp 6.
When the cable laying device works, an operator uses the saddle-shaped pulley special for cable laying in the well to lay cables in the well. Firstly, the length of the well edge fixing support 3 is adjusted through the adjusting hole 5 according to the size of a cable well mouth, after the well edge fixing support is adjusted to a proper length, the well edge fixing clamp 6 is firmly and reliably fixed on the well edge of the cable well through the fixing screw 7, and cables can be laid in the well through the saddle-shaped special pulley for cable laying in the well.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
