Abstract

The utility model provides a cable tunnel inspection shaft pulls cabling composite set, including set up respectively the well head crossbearer of well head top and below with support the crossbearer, the well head crossbearer with support the crossbearer and pass through the connecting rod connection for the motor -driven hank that promotes haulage cable grinds to be fixed on the well head crossbearer, installs the angle pulley on the support crossbearer, carries out 90 direction through the angle pulley with wire rope, pull the cabling in -process at the inspection shaft, can turn to traction force to need not install the reverse earth anchor that motor -driven hank ground, be particularly suitable for the cable laying in the cable tunnel of city, this project design is simple, low cost, and the equipment is convenient, and the effect is obvious, can solve the difficult problem in the construction.

Description

Cable tunnel inspection shaft traction cabling combination unit
[technical field]
The utility model belongs to cable construction technology, relates to a kind of cable tunnel inspection shaft traction cabling combination unit.
[background technology]
In cable laying work progress, at present not for the tractive effort guider of tunnel inspection shaft, there is no the unit equipment that can adapt to various inspection well head yet.
Site operation conventional method is: 1, destruction part checks the borehole wall, allows haulage cable with the angle of > 90 °, pulls out by force in tunnel, motor-driven grinding mill is exerted oneself increasing, steel wire rope occurs that angle is stressed, accelerates steel rope abrasion, lays increased risk.2, fixing motor-driven grinding mill needs to install earth anchor, but is hardened ground around city tunnel inspection shaft, cannot install earth anchor, make troubles to construction.3, adopt double steering pulley combination, steel wire rope need by 2 90 ° guiding, and strand mill tractive effort is about 30-40% and exerts oneself for overcoming angle with joint efforts, but power fails all to be converted into tractive effort, and the wearing and tearing of aggravation strand mill and steel wire rope, operating efficiency is low.
[utility model content]
For solving the problem, the utility model provides a kind of cable tunnel inspection shaft traction cabling combination unit, simplifies apparatus structure, improves propulsive efficiency, alleviate the wearing and tearing of strand mill and steel wire rope.
For achieving the above object, the technical solution of the utility model is as follows:
Cable tunnel inspection shaft traction cabling combination unit, comprise and be separately positioned on well head crossbearer above and below well head and supporting cross bearer, well head crossbearer is connected by connecting rod with supporting cross bearer, motor-driven grinding mill for promoting haulage cable is fixed on well head crossbearer, supporting cross bearer is provided with angle pulley, by angle pulley, steel wire rope is carried out 90 ° of guiding.
Further, described well head crossbearer and supporting cross bearer are by regulating the adjustable link of length to be connected.
Further, the coaster being arranged on cable tunnel inner support cable is comprised described in.
Further, described well head crossbearer and supporting cross bearer are made up of glass fiber compound material.
Further, described motor-driven grinding mill adopts spill take-up reel.
The utility model comprises and is arranged on well head crossbearer above and below well head and supporting cross bearer, supporting cross bearer is provided with angle pulley, changes tractive effort direction, solve tunnel inner cable and lay, horizontal direction traction problems.Motor-driven grinding mill is erected at inspection well head, vertical-lift, improves power-conversion efficiency, do not need earth anchor is installed simultaneously, simple and practical.
Further, well head crossbearer and supporting cross bearer, by the adjustable link of length can be regulated to be connected, by adjustment length of connecting rod, can be applicable to the inspection shaft type of different depth, different borehole wall thickness.Apparatus design is simple and practical, and assembling is quick, improves effect.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
In figure: 1-well head crossbearer, 2-motor-driven grinding mill, 3-supporting cross bearer, 4-angle pulley, 5-adjustable link, 6-cable, 7-coaster, 8-well head, 9-steel wire rope.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in detail:
See Fig. 1, the technical scheme that the utility model adopts is: the well head crossbearer 1 comprising the first half, fixing motor-driven grinding mill 2, and bears the effect promoting haulage cable 9.The supporting cross bearer 3 of the latter half, fix 1 angle pulley 4, by 90 °, steel wire rope guiding, well head crossbearer 1 and supporting cross bearer 3 are separately positioned on above and below well head 8, adjustable link 5, is connected and fixed lower cross frame, adapts to the tunnel construction of different depth, support whole device, holding device is stablized simultaneously.
Be in inspection shaft traction cabling process, tractive effort can be swung to, and do not need the reversal interlocking relay of motor-driven grinding mill, be particularly suitable for the cable laying in city cable tunnel, be applicable to cable tunnel inspection shaft cable laying operation, the combination unit that on-the-spot packaged type is installed, convenient and swift efficiency is high.According to site inspection well situation, can use, to inspection shaft without destruction in all size present situation, deep mixed environment at any time; Overcome the shortcoming that city hardened ground cannot install earth anchor.Improve the mode of 2 the 90 ° of angle pulleies generally adopted, simplify device, power is almost all converted into tractive effort, raises the efficiency, and alleviates the wearing and tearing of motor-driven grinding mill and steel wire rope.Inspection shaft traction cabling combination unit described in the utility model, assembles simple and practical.
In addition, be provided with the coaster 7 of carrying cable 6 in cable tunnel, described well head crossbearer 1 and supporting cross bearer 3 are made up of glass fiber compound material, and described motor-driven grinding mill 2 adopts spill take-up reel.
Before construction, the supporting cross bearer of the latter half is first put into inspection shaft, furnishing horizontal level.The well head crossbearer of the first half has been put at inspection well head simultaneously.Connect lower cross frame with regulating connecting rod, and according to inspection shaft wall thickness, regulating connecting rod position, guarantees device monolithic stability.
By the angle pulley of haulage cable in tunnel through the supporting cross bearer of the latter half, send to inspection well head and be connected with motor-driven grinding mill.
After conditioning equipment is normal, notice cable laying operation starts, and starts motor-driven grinding mill, and retracting steel wire rope, trailing cable moves horizontally in tunnel simultaneously.
The utility model structure is simple, easy to operate, safe and reliable, the time that can effectively construct, and avoids the other problems that may occur in numerous and diverse operation of maintenance and maintenance process, significantly can reduce the cost of overhaul, can promote the use of in similar industry field.
