Description
Technical field
The present invention relates to machine manufacture and electronic security(ELSEC) monitoring equipment technical field, be specifically related to a kind of tower machine jacking control monitor unit.
Background technology
Tower crane hydraulic jacking system realizes increasing or reducing standard knot by jacking and decline tower crane stock, makes tower crane raise along with depth of building change or to reduce, thus meets the vertical transport needs of differing heights building.But in jacking and decline process, also occur that tower machine overthrow accident is maximum.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, propose a kind of tower machine jacking control monitor unit, described management system is according to the jacking of tower machine or remove the object that standard knot job execution requires to realize supervision, prevents tower machine from jacking and decline process, occurring overthrow accident.
Technical scheme of the present invention is: a kind of tower machine jacking control monitor unit, comprise wheel bracket, master control system, Sensor output protecting pipe and guide wheel bench board, described wheel bracket is arranged on guide wheel bench board, described wheel bracket is provided with guide wheel, described Sensor output protecting pipe is fixed on guide wheel bench board, Sensor output is provided with in the inside of described Sensor output protecting pipe, be connected with sensor at Sensor output near one end of guide wheel, connect described master control system at the other end of Sensor output.
Warning device is provided with in described master control system.
Air velocity transducer is provided with in described master control system.
The present invention has following beneficial effect:
1) the present invention can detect automatically to the jacking of tower machine standard knot and unloading process, can automatic alarm.
2) the present invention can detect potential safety hazard in real time, by automatically detecting replacement manual detection, improves the safety of tower machine operation.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is the main TV structure schematic diagram of the present invention.
Fig. 2 is plan structure schematic diagram of the present invention.
In figure, 1, guide wheel; 2, wheel bracket; 3, Sensor output protecting pipe; 4, guide wheel bench board; 5, standard knot column; 6, sensor; 7, Sensor output.
Detailed description of the invention:
Shown in Fig. 1 and Fig. 2, the present invention includes wheel bracket 2, master control system, Sensor output protecting pipe 3 and guide wheel bench board 4, described wheel bracket 2 is arranged on guide wheel bench board 4, described wheel bracket 2 is provided with guide wheel 1, described Sensor output protecting pipe 3 is fixed on guide wheel bench board 4, Sensor output 7 is provided with in the inside of described Sensor output protecting pipe 3, be connected with sensor 6 at Sensor output 7 near one end of guide wheel 1, connect described master control system at the other end of Sensor output 7.Warning device is provided with in described master control system.
In the course of the work, the present invention can realize detecting potential safety hazard in real time in the jacking of tower machine and demolishing process, observing, can watch procedure for displaying by automatically detecting alternative special messenger in driver's cab.Described system can detect the wind scale of jacking or demolishing process, and wind scale should meet less than 4 grades, reports to the police more than more than 4 grades; When crane arm rotates to the front of jacking stock, system provides distance braking signal, and top swing type mechanism is braked by navigating mate, and feeds back " execution " signal; Make piston rod stretch out 20-30mm when starting hydraulic efficiency pressure system, device sends danger signal, and navigating mate stops oil cylinder upward movement, and system is after obtaining oil cylinder danger signal, and prompting driver makes amplitude variation trolley outwards run from arm root, and shows miles of relative movement; Bottom stock, surrounding installs four detecting elements, and when the gap when between bottom guide wheel and tower body main chord is about 2mm, system sends amplitude variation trolley stop signal; Hydraulic efficiency pressure system is started in prompting makes piston rod continue upward movement, when device detects that climbing pawl rests on marking time of standard knot, after determining bearing pin and marking time and be separated completely, system can send oil cylinder piston retraction signal, tower crane hydraulic jacking system realizes increasing or reducing standard knot by jacking and decline tower crane stock, make tower crane raise along with depth of building change or to reduce, thus meet the vertical transport needs of differing heights building.But in jacking and decline process, also occur that tower machine overthrow accident is maximum.This covering device is exactly according to the jacking of tower machine or removes the object that standard knot job execution requirement realizes supervision.Standard knot column 5 is provided with tower machine standard knot, when standard knot increased by needs, to start on this device after " jacking " button, show the position of current wind speed and rotary disk, crane arm is rotated to the direction of introducing tower-body standard section (crane arm be positioned on climbing support directly over overhanging framework).Send danger signal after lift oil tank bar moving 20-30mm, and show " adjusting little truck position ", when the gap when between bottom guide wheel and tower body main chord is about 2mm, system sends " luffing parking " signal.Start hydraulic efficiency pressure system, make to climb pawl and rest on marking time of tower body.System sends " receipts cylinder " signal, namely completes the supernumerary segment work of a joint standard knot.When dismounting standard knot, press the laggard line operate of " dismounting " button on this device.
The present invention has the following advantages:
1) the present invention can detect automatically to " jacking " and " dismounting " of the standard knot 5 of tower machine;
2) by four sensors 6 bottom stock, detect the gap between the guide wheel 1 of bottom and tower body main chord, tower machine upper center of gravity is dropped on the position of jacking cylinder beam, guarantees not produce skew, record the trim position of amplitude variation trolley simultaneously;
3) by the signal that sensor 6 is measured, detect two activities of climbing support and climb pawl and hang over exactly and mark time in the arc groove of top.
