Abstract
The invention discloses a device for controlling the central verticality of a cooling tower. The key technical scheme is that: the device comprises a hanging disk, rollers and pull ropes, wherein a laser plumb aligner is arranged in the center of a base plate of the cooling tower; a receiving target is arranged in the center of the lower surface of the hanging disk; a camera is arranged below the hanging disk outside one side of the receiving target, is opposite to the receiving target in an inclined manner, and is electrically connected with a monitoring instrument on a construction flat frame; a shell for covering the laser plumb aligner is arranged on the base plate of the cooling tower; and light-transmitting glass is arranged at the top end of the shell. Compared with the prior art, the device has the outstanding advantages of high detection precision, convenience in adjustment and high efficiency.
Description
Technical field:
The present invention relates to a kind of measuring technique, particularly a kind of cooling tower central vertical degree control device.
Background technology:
Need in the double-curve cooling column architectural process at any time tower body to be detected, guarantee that tower body remains in the accuracy rating of designing requirement.Existing detection control method is at first on the tower base plate, to find out central point, suspention one hanging scaffold in the cooling tower mouth; This hanging scaffold is in the center of tower body; Whether artificial center at hanging scaffold overlaps with central point on the tower base plate with plumb bob, when plumb bob departs from the base plate central point, tower mouth off-design center is described; Can move to the design centre this moment through the hanging scaffold that suspention was received or put to reel; The mechanism that moves hanging scaffold is, forward and backward a, left side and right place tower base plate central point outside respectively are provided with a manual reel, and its other end is connected with four reels respectively an end of stay cord is connected this pulley on the tower body platform of restricting respectively with hanging scaffold after; According to hanging scaffold adjustment position, thereby guarantee to cool off in the accuracy rating that tower body is controlled at design code.Thisly measure the off-centered method of tower body with plumb bob, to be that precision is low be difficult for reaching design standard to its shortcoming, and in that to measure adjustment process efficient low.
Summary of the invention:
The purpose of this invention is to provide the high and high a kind of cooling tower central vertical degree control device of efficient easy to adjust of a kind of certainty of measurement.Technical solution of the present invention is; Comprise hanging scaffold, reel and stay cord; It is characterized in that: be provided with a laser plummet in the base plate center of cooling tower; Soffit center at hanging scaffold is provided with receiving target, and it is tiltedly right mutually with receiving target that camera is installed in the below of the outer hanging scaffold of receiving target one side, and this camera is electrically connected with the monitor that construction is put down on the frame.On the cooling tower base plate, be provided with a housing with the laser plummet cover within it, the top of this housing is the glass of printing opacity.The present invention and prior art relatively have the high and high remarkable advantage of efficient easy to adjust of accuracy of detection.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
In conjunction with following embodiment the present invention is described in detail; Be provided with a laser plummet 2 in the center of cooling tower base plate 1; Hanging scaffold 10 soffit centers are provided with receiving target; It is tiltedly right with receiving target on the outer rim of hanging scaffold, to be provided with camera 7, and the monitor 9 on the special-purpose level bridge 8 of this camera and cooling tower construction electrically connects.The present invention does not change the translation mechanism of hanging scaffold.
Operation of the present invention and detection method are; In the time need detecting (receiving target of cape is in the center of tower body) to the cooling tower mouth; At first make the unlatching laser plummet, laser beam is mapped on the receiving target, and the constructor of the special-purpose level bridge of hydraulic construction can be observed promptly through monitor that the laser beam of being seen off by the camera transmission overlaps with the receiving target central point or direction that departs from and depart from and the amount that departs from; When departing from and exceeding the design permissible value; Personnel on the staffing cooling tower base plate of construction on the level bridge, the rotation through reel 4 drives stay cord 5 moves hanging scaffold, up to laser beam with till the receiving target central point overlaps; The hanging scaffold of constructor according to this time is the template position of center of circle adjustment cast tower body, and the tower body 6 of cast is controlled in the accuracy rating of design code.In order to protect laser plummet; Housing 3 is set on the cooling tower base plate laser is hung down accurate cover within it; The top of this housing is a transparent glass; The laser beam that laser plummet is sent can shine on the receiving target, above above-mentioned light transmission glass plate, is provided with protective screening, prevents that the junk of tower top from damaging glass plate.
Claims (2)
1. cooling tower central vertical degree control device; Comprise hanging scaffold, reel and stay cord; It is characterized in that: be provided with a laser plummet in the base plate center of cooling tower; Soffit center at hanging scaffold is provided with receiving target, and it is tiltedly right mutually with receiving target that camera is installed in the below of the outer hanging scaffold of receiving target one side, and this camera is electrically connected with the monitor that construction is put down on the frame.
2. a kind of cooling tower central vertical degree control device as claimed in claim 1, it is characterized in that: on the cooling tower base plate, be provided with a housing with the laser plummet cover within it, the top of this housing is the glass of printing opacity.
