Abstract
Disclosed is a laser display and supervision device for declination angles of a crane lift hook. The objective of the arrangement is to display and supervise with laser the direction and dimension of declination angles of a crane lift hook in the process of lifting. The invention is characterized in that: a reference laser generator hingedly connected by a ball is arranged below the exterior side of a protective clamping plate of a movable pulley block which is connected with the lift hook; a lift hook declination angle laser generator is arranged above the exterior side of the protective clamping plate of the movable pulley block; when a lift hook declination angle is zero degree, the center line of a laser beam downwardly transmitted by the lift hook declination angle laser generator overlaps the center line of a plumbed laser beam upwardly transmitted by the reference laser generator; when a lift hook declination angle appears, the lift hook declination angle beam deviates from the reference laser beam, and the red color and the blue color make the direction and declination degree of the declination angle be clearly revealed; laser beam images of the direction and dimension of declination angles are displayed and reproduced on a screen in a control chamber during lifting through a wireless receiver in the control chamber of the crane and through a wireless camera which is arranged on the exterior side of the protective clamping plate of the movable pulley block through hinged connection by the ball.
Description
The drift angle laser display of technical field hoist lifting hook and monitor unit (this device, lower with) belong to crane hanging component monitoring technique field, and exactly it is a kind of device of monitoring crane vertical lifting.
background technology runabout crane or crane (crane, lower same), horizontally-arranged vertical weight is lifted when vertical, subsidiary engine is lifted the ratio that send speed and main frame hoisting speed, should equal the slope of main and auxiliaries suspension centre line, lifting when subsidiary engine send speed not catch up with or when too fast, suspension hook all can produce the drift angle, when also having the lifting of double-machine lifting crane weight asynchronous, suspension hook also can produce the drift angle, and the crane poor stability requires vertical lifting, yet in reality, the driver can't judge but that weight lifts or two independent suspension centres and above while (are not only two-shipper when stressed, the multimachine lifting, also has the unit sliding method, during rotary process lifting weight), whether its suspension hook is in plumbness, and will be by the lifting director, control according to monitoring the information conductor driver that lifted weight thing vertical lifting person provides, not only untimely but also inaccurate
summary of the invention is in view of lifting or two independent suspension centres and the stressed lifting of above while are that a large amount of the existence (lifts operation because be not only, also comprise the operation of part single crane hoisting), and main in vertical weight lifting, between the subsidiary engine suspension centre, the slope of line is in continuous change, especially the more difficult control of lifting under big-elevation ... thereby set up demonstration, monitor the setting of crane vertical lifting, overcome the risk that lifts middle out of plumb lifting, exploitation both had been suitable for all single crane hoistings, also be suitable for lifting operation, change the supervision setting of crane, with provide according to being the task of top priority for eliminating the suspension hook drift angle, therefore this device namely arises at the historic moment.
This device is compared with 200910112531.9 crane vertical lifting laser monitoring devices [P], following characteristics are arranged: because the core of controlling the crane vertical lifting is to control the drift angle of its suspension hook, this device is namely realized the direct supervision to the hoist lifting hook drift angle, provide foundation for control eliminating the suspension hook drift angle simultaneously, this is large characteristics of this device; This installs another characteristics, when using laser as crane vertical lifting benchmark, shows again the deflection of hoist lifting hook with dynamic Laser, and is directly perceived, distinct; Three of characteristics, this device reference laser producer and suspension hook drift angle laser generator need height or the length of Emission Lasers light beam, and be irrelevant with length of boom, angle in crane lifting; Four of characteristics, this device have hoist lifting hook drift angle laser writer, hoist lifting hook drift angle laser display post, hoist lifting hook drift angle laser monitoring device, the hoist lifting hook drift angle laser horizontal magnification monitor unit of multiple pattern for the crane apolegamy
This section deletion
One of this device, hoist lifting hook drift angle laser display post.Be characterized in, will connect, launch the vertical reference laser producer of laser beam up all the time through ball strand, be installed in the lower position in the running block retaining clip plate outside that links with hoist lifting hook; With suspension hook drift angle laser generator, be installed in the top position in the running block retaining clip plate outside that links with hoist lifting hook, and when satisfying 0 ° of hoist lifting hook drift angle, the laser beam line of centers that suspension hook drift angle laser generator is launched down, the laser beam line of centers of launching up with reference laser producer vertical coincides.
Two of this device, hoist lifting hook drift angle laser monitoring device.Be characterized in, the running block retaining clip plate outside that is linking with hoist lifting hook, when hoist lifting hook drift angle laser display post is set, wireless camera after the ball strand connects is set, install wireless receiver in the crane operation chamber, laser beam image with hoist lifting hook drift angle laser display post in lifting shows is reproduced on the screen of driver operation chamber.
Three of this device, hoist lifting hook drift angle laser horizontal magnification monitor unit.Be characterized in, the running block retaining clip plate outside that is linking with hoist lifting hook, when hoist lifting hook drift angle laser display post is set, wireless camera after the ball strand connects is set, and install wireless receiver in the crane operation chamber, laser beam image with hoist lifting hook drift angle laser display post in lifting shows after picture slope treater is separately with the image horizontal magnification, is shown on the screen of driver operation chamber.
