Abstract
The utility model relates to a weight-number displaying multifunction controlling instrument for a crane, which comprises the existing control display and a sensor which is provided with two pin shafts, one pin shaft is connected with a central shaft, the other end of the central shaft is provided with a nut, and the central shaft is wound with a spring. The utility model is characterized in that a draw plate is arranged in a groove of the central shaft, a guide shaft and an electric displacement sensor are installed on the draw plate, and the guide shaft is provided with a collision block. A radial thrust bearing and a radial ball bearing are installed between the central shaft and a casing. The utility model has convenient installation and no installation error, and the utility model has twist prevention function for a steel cable.
Description
The utility model relates to the safety guard that crane load shows, controls.
Known to the applicant, a kind of weight sensor killer is arranged now, the hoisting capacity of hoisting crane there is control action.This killer reflects the pull of steel wire weight of heavy that promptly hoists indirectly with the tension of test hoist rope, produces displacement at the tension effect lower spring of steel rope, sends electric command signal by this displacement, makes lift heavy obtain restriction.But this displacement is an amount of nonlinearity, so it is become comparatively difficulty of numeric display, simultaneously owing to be subjected to the influence of installation site precision, its displacement changes greatly, therefore must debug to the erecting stage, and also more complicated of debugging work.
The purpose of this utility model provides a kind of hoisting crane weight digital display and shows the multi-functional control instrument, and it can remedy the above-mentioned deficiency of existing apparatus.
The utility model comprises an existing control telltale and a sensor, the latter has 2 bearing pins, a bearing pin is connected with center shaft, the other end of center shaft is equipped with nut, be wound with spring on the center shaft, it is characterized in that in the groove of center shaft arm-tie being housed, guide shaft and electronic displacement sensor are contained on the arm-tie, and collision block is housed on the guide shaft.
The utility model is easy for installation, no installation error, and steel rope had the anti-function of turning round.
Below by embodiment and description of drawings the utility model.
Accompanying drawing 1 is the structural representation of the utility model sensor.
Accompanying drawing 2 is its cutaway view.
The utility model is made up of existing digital display type controller and sensor.This sensor has 2 bearing pins (1) and (10), and bearing pin (10) is connected with the center shaft that has otic placode (8), and the other end of center shaft (8) is equipped with circular nut (12), is wound with spring (13) on center shaft (8), and arm-tie (6) is housed in the groove of center shaft (8).At center shaft (8) radial-thrust bearing (16) and radial ball bearing (15) are housed between spring (13) and arm-tie (6) upward.Guide shaft (2) and electronic displacement sensor (3) are contained on the arm-tie (6) by nut (7) and (9) respectively.Guide shaft (2) is equipped with 2 collision blocks (4) by screw.Electronic displacement sensor (3) is connected with digital display controller (not drawing among the figure) by cable (11).
When using the utility model, sensor casing (14) is connected with the crane arm of hoisting crane by its bearing pin (1), is connected with crane rope by another bearing pin (10).Steel wire pulling force on acting on bearing pin (10) by center shaft (8) and on circular nut (12) when passing to spring (13), after having overcome spring force, produce a displacement, this displacement is delivered on the arm-tie (6), so guide shaft (2) all obtains identical displacement with electronic displacement sensor (3).If this displacement has reached the limit of hoisting capacity; just open the micro-switch (5) of sensor by collision block (4); thereby played the safety control defencive function that hoisting capacity is given the police, reports to the police and limited the biggest lifting capacity; by electronic displacement sensor (3) this displacement is become electric signal simultaneously; pass to the digital display controller that places in the driver's cab by cable (11) again, the latter can demonstrate the lift heavy amount of hoisting crane.The control display instrument can send multiple different electrical equipment command signal and sound and light signal simultaneously, and hoisting crane is had speed limit, gives safe, control defencive function alert, that report to the police.The utility model has machinery, electronics double protection functions.
Because 1 radial-thrust bearing (16) and radial ball bearing (15) are installed between center shaft (8) and the casing (14), center shaft (8) is so can freely rotate it in addition to the anti-function of turning round of steel rope in casing.
The utility model can be used for various tower cranes and various elevator machinery and erecting equipment, need not field adjustable.
Claims (2)
1. a hoisting crane weight digital display shows the multi-functional control instrument, comprise an existing control telltale and a sensor, the latter has 2 bearing pins (1) and (10), a bearing pin (10) is connected with center shaft (8), the other end of center shaft (8) is equipped with nut (12), is wound with spring (13) on the center shaft (8), it is characterized in that being equipped with in the groove of center shaft (8) arm-tie (6), guide shaft (2) and electronic displacement sensor (3) are contained on the arm-tie (6), and collision block (4) is housed on the guide shaft (2).
2. controller as claimed in claim 1 is characterized in that installing 1 radial-thrust bearing (16) and radial ball bearing (15) between center shaft (8) and casing (14).
