Abstract
The utility model discloses a three-pulley type weight sensor, which belongs to the field of tower crane parameter measuring devices. The three-pulley type weight sensor comprises pulleys and lateral plates, wherein the three pulleys are arranged between the two lateral plates, a shaft type weight sensor is further disposed between the lateral plates, and the pulleys are made of wear resistant materials Cr12. The two lateral plates are fixed with anti-rotating clamp plates. One side of a middle pulley shaft on the lateral plates is provided with an anti-rotating clamp plate. Each anti-rotating clamp plate is a rectangular metal plate, and the edges of each anti-rotating clamp plate contact with the shaft end of the middle pulley shaft. The three-pulley type weight sensor utilizes a three-pulley structure, has more mounting positions, is more flexible in mounting mode, utilizes the Cr12 wear-resistant materials to manufacture the pulleys, strengthens wear resistance of the pulleys, prolongs service life, and further guarantees safety of a tower crane.
Description
Technical field
The utility model relates to a kind of weight sensor, specifically is a kind of three pulley-type weight sensors that are applied to the tower machine.
Background technology
In the hoisting device field, accurately induce heavy amount and signal passed to control module most important to the safe operation of hoisting device.Existing weight sensor mostly is that bearing-type, plate ring are pull-type, pillar etc., the bearing-type sensor requires reducing gear one side that the axle housing support is arranged, the plate ring is pull-type to require wire rope winding place that not running rope must be arranged, reserve the power taking space when pillar requires the hoisting device design, these characteristics cause being subjected to the restriction of objective condition when using these sensors.ZL200820230495.7 discloses a kind of three pulley force cells, though solved the problem that the sensor exists, because of the pulley of its use is to adopt nylon material to make, wearing quality is good inadequately, fall short of serviceable life, has very big danger when the tower machine moves under rugged surroundings.
Summary of the invention
The purpose of this utility model is to provide the three pulley-type weight sensors that a kind of wearing quality is good, safety coefficient is high.
Three pulley-type weight sensors described in the utility model comprise pulley, side plate, and wherein three pulleys are installed in the middle of two side plates, and the axonia weight sensor also is set in the middle of the side plate, and described pulley adopts high-abrasive material to make.Pulley is all fixedlyed connected with side plate with axle type weight sensor, when wire rope is exerted pressure to middle pulley, simultaneously side plate there is a pulling force, side plate has relative motion trend with axle type weight sensor, cause a type weight sensor to be subjected to the pulling force effect, produce electric signal, pass to ECU (Electrical Control Unit) by connected output cable and shown.
In the said apparatus, the high-abrasive material that described pulley adopts is Cr12.Because of hoisting weight is bigger, the wire rope tensile force is big, and pulley weares and teares easily, and for guaranteeing the security of tower machine operation, pulley must be selected the good material of wearing quality for use, so the utility model adopts the Cr12 of high abrasion to make pulley.
For the rotation of preventing limited slip wheel loading process axis influences measurement result, the utility model is fixed with antiturning fastener board on biside plate.Described antiturning fastener board is a rectangular metal plate, and its edge contacts with intermediate pulley axle axle head.Antiturning fastener board can be a rectangular steel plates, also can be the rectangular slab of other material.Be screwed in the pulley spindle axle head outside, be close to pulley spindle.
The utility model adopts three pulley structures, raising line is walked around in the middle of pulley, by side plate axle type weight sensor is applied power, therefore make that the installation site of weight sensor is more, mounting means is more flexible, and the Cr12 making pulley of the utility model employing high abrasion, has strengthened the wearing quality of pulley, increase serviceable life, guaranteed the security of tower machine more.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
Embodiment of the present utility model comprises pulley 1,3,5, side plate 2, wherein three pulleys 1,3,5 are installed in the middle of two side plates 2, axonia weight sensor 8 also is set in the middle of the side plate 2, two side plates 2 are used bolt, described pulley 1,3,5 adopts high-abrasive material Cr12 to make, and is fixed with antiturning fastener board 4 on the biside plate 2.Antiturning fastener board 4 is a rectangular steel plates, is positioned at the pulley spindle outside, and its edge contacts with intermediate pulley axle axle head.Side plate 2 is provided with mounting hole 6.
Mounting means one as shown in Figure 3, welding one erecting frame 11 on the vertical frame of tower cap 9, with screw this device is fixed on (position of erecting frame 11 will make two pulleys 1,5 up and down of this device just in time paste mutually with raising line 10) on the erecting frame 11, raising line 10 passes in the middle of three pulleys 1,3,5, when slinging weight, raising line 10 tensions, intermediate pulley 3 is stressed, make a type weight sensor 8 stressed and be translated into electric signal by side plate 2, pass to main control unit by connected output cable 7 and differentiate weight of heavy.
Mounting means two as shown in Figure 4, welding one erecting frame 11 on the top boom of balance arm 14 roots, with screw this device is fixed on the erecting frame 11, after raising line 10 is walked around angle sheave 12 on the balance arm 13, pass in the middle of three pulleys 1,3,5, axle type weight sensor 8 induced signal processes are with installation mode one.
