In technique scheme, also comprise: detecting device is connected to controller, first distance measuring equipment (DME) 5 and second distance measuring equipment (DME) 6; After counterweight oil cylinder 1 and counterweight hook 2 is connected; Send acknowledgment signal in place to controller, after second height 61 reaches the first predetermined threshold value scope, send first acknowledgment signal to controller; Confirm that clump weight leaves bench board 4; And after first height 51 reaches the second predetermined threshold value scope, send second acknowledgment signal to controller, confirm counterweight oil cylinder 1 withdrawal fully.In this technical scheme, the mode of operation of counterweight oil cylinder, clump weight is pass by in real time, so that carry out next step action, both saved the time of artificial affirmation, also can avoid meeting accident.
In technique scheme, also comprise: read out instrument, be connected to controller, receive first altitude signal, second altitude signal and the clump weight altitude signal of self-controller, and show.In this technical scheme, for the data in the working process, can be presented in real time on the telltale, check for the staff.In the process that shows, can adopt the relevant digital data of direct demonstration, also can adopt and convert digital numerical value into patterned mode, and, realize understanding the counterweight process through real-time cartoon scene.
And because the quantity of each clump weight of installing 3 is inconsistent; Therefore and order is indefinite, and convenient on using can all be installed a distance measuring equipment (DME) at the lower surface of each clump weight 3; Shown in Fig. 4 B, clump weight 31 has been installed distance measuring equipment (DME) 601, clump weight 32 has been installed distance measuring equipment (DME) 602.For the distance measuring equipment (DME) on the clump weight 31 601; In the process that clump weight 32 is assembled; What measure is the distance 6011 between clump weight 31 and the clump weight 32, and the distance measuring equipment (DME) 602 on the clump weight 32, what obtain then is the distance 6021 between clump weight 32 and the bench board 4.Can know that along with the rising of clump weight 32, distance 6011 will be dwindled thereupon; Distance 6021 then increases thereupon; When clump weight 32 be assembled finish after, then distance 6011 is 0, certainly owing to install and possibly have certain error; Should then be the second distance 61 among Fig. 4 A that is equivalent to that need obtain apart from 6021 near certain numerical value in one of the 0 less number range.
When being installed to the clump weight lower surface, for the ease of enforcement, cooresponding signalling methods can adopt communication.
In technique scheme, also comprise: the lower surface of clump weight is provided with a groove, and second distance measuring equipment (DME) 601 or 602 is arranged in the groove.In this technical scheme; Because clump weight adopts closely overlapped way to install and put; Therefore for the distance measuring equipment (DME) that is mounted is not damaged, can be installed in the groove on the lower surface of clump weight, contact with other clump weights or bench board between avoiding.
More than be described with reference to the accompanying drawings the technical scheme of the utility model, considered in the correlation technique, only can detect whether counterweight has been installed, and can't obtain concrete numerical value.Therefore, the utility model provides a kind of counterweight detecting device and a kind of weight-lifting equipment, can measure the height of counterweight, thereby learn the weight of the counterweight of having installed, and realizes easily the judgement of the lifting performance of hoisting crane and the selection of operating mode.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
