The brake glide quantity detector of the crane is an integrated mechanical and electronic software instrument which is compact, portable and simple in operation. The brake glide quantity of the crane can be quickly measured on the ground; the principle and the method of the instrument are simple and reliable; and the detector can be widely applied to measuring the brake glide quantity of various cranes with high measurement accuracy and good real-time property.
Description
Technical field
The utility model relates to a kind of detecting instrument that is exclusively used in the brake slide figureofmerit of various hoisting machinery lifting mechanism.
Background technology
Crane brake slide amount is an important indicator of crane safety performance, need often detect.Provide two kinds of conventional sense methods in the standard of crane safety calibrating at present, method 1: adopting diameter is the 1mm wire rope, one end is a little stone roller, the other end links to each other with the microswitch of fixing (contact is normally closed), normally closed contact is connected in the decline loop of controlling with contactor, the quality of stone roller should be enough to make switch motion, cut off the decline circuit, little stone roller is placed on the load (counterweight) during measurement, when rated load so that shelves are when dropping to a certain position at a slow speed, little stone roller separates with load, the circuit that descends this moment is cut off immediately, load begins the braking that descends immediately, after treating that rated load is stopped, record the vertical range between little stone roller and the load, be descending braking distance, its mean value is got in tie-in three times.Method 2: adopt the measuring instrument of " measuring wheel+incremental-rotating coder+counter " combination, detect the descending braking distance of lifting mechanism.Counter circuit with measuring instrument links to each other with controller earlier, guarantees rated load with in descending at a slow speed, and the unison counter that controller is got back to the outage of zero-location control circuit counts from zero.During detection measuring wheel is touched in (touch should be not more than 60N) reel ends outer radius, after rated load stops with the braking that descends at a slow speed, read the count value K of counter, as the raw data of conversion braking distance.
The instrument and the method measuring accuracy of above-mentioned detection crane brake slide amount are low, and real-time is poor, and are not easy to operation.
The utility model content
Conventional crane brake slide amount detecting instrument measuring accuracy is low, real-time is poor in order to solve, be not easy to problems such as operation, and the utility model provides a kind of crane brake slide amount detector.
The technical scheme that the utility model is adopted for achieving the above object is: crane brake slide amount detector, it is characterized in that: comprise computing machine (1), video camera (2), wireless data transmission and control device (3) and height gauge (5), video camera (2) is connected with computing machine (1).
Described video camera (2) is made of optical imagery camera lens and image-forming component.
The transmission data pattern of described wireless data transmission and control device (3) has wireless and wired two kinds.
Described height gauge (5) is the ruler that has the measurement length of scale.
Crane brake slide amount detector of the present utility model is compact portable, the soft integrated instrument of ray machine zooming simple to operate, can finish the surveying work of crane brake slide amount fast on ground, the principle of instrument method is simple and reliable, be widely used in the measurement of the brake slide amount of various crane, the measuring accuracy height, real-time is good.
Description of drawings
Fig. 1 is the composition structural drawing of the utility model crane brake slide amount detector;
Embodiment
Crane brake slide amount detector as shown in Figure 1, comprise computing machine 1, video camera 2, wireless data transmission and control device 3 and height gauge 5, video camera 2 is installed on the tripod 4, and video camera 2 is connected with computing machine 1, to computing machine 1 screen output measurement image.Wireless data transmission and control device 3 have wired and wireless two kinds of data-transmission modes, are connected with computing machine 1 by wired or wireless mode, are mainly used in the real-time control of crane electrical control cubicles brake loop.Height gauge 5 is fixed on the height gauge fixed mount 6, and height gauge 5 is the ruler that has the measurement length of scale.Video camera 2 is for comprising the specialized camera of imaging lens and CCD or cmos imaging element.
Operation and implementation process are as follows: height gauge 5 is fixed on the Crane Load that has hoisted, height gauge 5 will show the height value of load apart from ground in real time, then video camera 2 image-capturing apparatus are installed, make it can the in real time clear scale value of observing height gauge 5 on computing machine 1 screen.Wireless data transmission is connected respectively on computing machine 1 and the crane electrical control cubicles brake loop with the transmitting terminal and the receiving end of control device 3, but realization is by the closure state of computing machine 1 application software real-time radio control crane brake loop.Send instruction and carry out picture catching by computing machine 1 application program, closed brake loop was braked after the wireless receiving termination was received instruction, from image, can read h1 on the height gauge data of braking point, treat to catch the height gauge image once more and read h2 on the altitude information after load is stablized, the brake slide amount is Δ h=h1-h2.
Claims (4)
1. crane brake slide amount detector, it is characterized in that: comprise computing machine (1), video camera (2), wireless data transmission and control device (3) and height gauge (5), video camera (2) is connected with computing machine (1).
2. crane brake slide amount detector according to claim 1, it is characterized in that: described video camera (2) is made of optical imagery camera lens and image-forming component.
