Abstract
The invention provides a large-scale suspended box cofferdam location fair lead and a location method thereof, and the structure of the invention is a steering device and also a transition device of a fixed seat and a connection plate, wherein, one end of the steering device is connected with the fixed seat through a transverse axis pin; the other end of the steering device is connected with one end of the connection plate through a vertical axis pin; the other end of the connection plate utilizes a plurality of groups of axis pins to combine a traction box through which a fair lead traction rope can pass; the axis pin and a steel sleeve are the bearings of the traction box which is at the end of the connection plate. The location method is as follows: arranging a fixed seat on the outer wall of the suspended box cofferdam; connecting the fixed seat, the steering device and the connection plate through axis pins to form a complete tensile system which can rotate flexibly; installing the traction rope in place by the axis pin traction box after the installation of the fair lead; adjusting the suspended box cofferdam to a specified location and realizing precise location. The invention has the advantages of simple structure, convenient operation, definite stress and low cost which can be used for precise location of other large-scale steel structure devices on the water and on the land, thus having greater promotion value.
Description
Technical field
The present invention relates to location, the suspension box-cofferdam fairlead apparatus of all kinds, various tonnages, be connected with chock, realized the accurate location of suspension box-cofferdam, belonged to technical field of civil engineering by the holder that is arranged on the suspension box-cofferdam outer wall.
Background technology
The movable fairlead of heavy steel cofferdam positioning wire cable is one always at present problem to be solved, the habitually in the past consistent practice is on steel cofferdam, if holder connects angle pulley again and waits and realize that the steel wire cable turns to adjusting, this kind method is applicable to the minor diameter wire rope
This device is prone to the phenomenon of wire rope job-hopping simultaneously, for major diameter steel wire cable
As adopt this kind mode need cast major diameter
Wheel shank, processing cost are higher.
Summary of the invention
The objective of the invention is to overcome above-mentioned existing safety defect, outer wall is provided with holder in original suspension box-cofferdam, utilize bearing pin to be connected with transfer, transfer is connected with equipment such as junction plate, pull ropes by bearing pin again, and form can about, about adjust direction and pinpoint large-scale suspended box cofferdam is located chock.Use this device not only can save unnecessary in the past construction cost, and it is dangerous to reduce construction, shortens the construction period.
Technical solution of the present invention: large-scale suspended box cofferdam location chock, it is characterized in that comprising holder, transfer, junction plate, horizontal bearing pin, vertical bearing pin, bearing pin, steel sleeve, wherein transfer is the transition apparatus of holder and junction plate, and an end of transfer is connected with holder by horizontal bearing pin; The other end of transfer is connected with an end of junction plate by vertical bearing pin, and the other end of junction plate utilizes some groups of bearing pins to form can wear the traction case of leading the cable pull rope, and bearing pin and steel sleeve are the bearings of the traction case of junction plate termination.
The localization method of large-scale suspended box cofferdam location chock is characterized in that this method comprises the steps:
One, at the suspension box-cofferdam outer wall holder is set;
Two, utilize horizontal bearing pin holder, transfer and junction plate to be connected, make it to form a complete tension system with vertical bearing pin;
Three, after chock installed, the vertical bearing pin traction case by chock was in place pull rope, by the traction of hoist engine or other plant equipment the appointment address is adjusted in the suspension box-cofferdam, realizes accurately location.
Advantage of the present invention: outer wall is provided with holder in original suspension box-cofferdam, utilize bearing pin to be connected with transfer, transfer is connected with equipment such as junction plate, pull ropes by bearing pin again, and form can about, about adjust direction and pinpoint large-scale suspended box cofferdam is located chock.Use this device not only can save unnecessary in the past construction cost, and it is dangerous to reduce construction, shortens the construction period.Simple in structure, easy to operate, stressed clear and definite, with low cost, through suitably improving, also can be applicable to waterborne, the land accurate location project of other large-scale steel structure equipment, have bigger promotional value.
Description of drawings
Accompanying drawing 1 is the main TV structure schematic diagram (the A-A cut-away view among Fig. 2) of large-scale suspended box cofferdam location chock.

Among the figure 1 is holder, the 2nd, transfer, the 3rd, junction plate, the 4th, horizontal bearing pin, the 5th, vertical bearing pin, the 6th, bearing pin, the 7th, steel sleeve.
The specific embodiment
Described holder 1 is the utensil that is provided with at the suspension box-cofferdam outer wall, makes it to form integral body with the cofferdam, plays the effect of " hanger ".
Described transfer 2 is heavily to be crucial position in the whole utensil, the transition apparatus of holder 1 and junction plate 3, and the one end is connected with holder 1 by horizontal bearing pin 4; The other end is connected with junction plate 3 by vertical bearing pin 5, thus about the realization, about the direction adjustment.
Described junction plate 3 is equivalent to the terminal of whole chock, and an end is connected with transfer 2 by bearing pin 5; The other end utilizes some groups of C bearing pins 6 to make can wear the traction case of leading the cable pull rope.C bearing pin 6 and steel sleeve 7 are the bearing of the traction case of junction plate 3 terminations.
This device has the bearing pin of three kinds of specifications, and effect is separately all arranged in device.Laterally bearing pin 4 be transfer 2 with holder 1 between the horizontal bearing pin that is connected, can realize rotating up and down by it; Vertical bearing pin 5 be transfer 2 with junction plate 3 between the vertical bearing pin that is connected, can realize left-right rotation by it; A bearing pin 6 and steel sleeve 7 are the bearing of the traction case of junction plate 3 terminations, can make by it and lead the cable pull rope and move around preferably in the case in traction.In use convenient flexibly for this device, all bearing pins, steel sleeve, perforate inwall all need polish and hold out against processing.
