Problems solved by technology

[0007] According to the above working principle, the force on the pivot pin sensor is only related to the angle of the wire rope bypassing the guide pulley, and there is no problem of uneven force measurement caused by the change of the weight of the wire rope due to the change of the lifting height in the first technique
However, due to the change of the angle of the wire rope on the guide pulley, the actual component force is too small
The signal amplification accompanied by its sensor makes the error larger, which is also not conducive to accurately detecting the change of the actual lifting weight

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 , figure 2 , image 3 The new weighing device structure of the shipbuilding gantry crane shown in has a pulley frame 1 on which a fixed pulley shaft 6 is fixed, and no less than two fixed pulleys 9 are symmetrically sheathed on the fixed pulley shaft 6 . On the fixed pulley shaft 6 and positioned at the center of the fixed pulley, a weighing pulley frame 7 is overcoated, and the weighing pulley frame 7 lower ends are provided with a weighing pulley 4 . The center of the weighing pulley 4 is equipped with a pin-type sensor 5 that is also used as a pulley shaft, and a bushing II 3 is set between the sensor 5 and the pulley 4, and the bushing II 3 can ensure the mutual assembly of the weighing pulley 4 and the sensor 5 size. In order to prevent the sensor 5 from moving axially, a baffle 8 is provided on the side of the...

Abstract

The invention discloses a novel weighing device structure of a shipbuilding gantry crane, characterized in that: the structure is provided with a pulley yoke, a fixed pulley shaft is fixed on the pulley yoke, no less than two fixed pulleys are sleeved on the fixed pulley shaft symmetrically; a weighing pulley yoke is sleeved on the fixed pulley shaft and arranged between the fixed pulleys, the lower end of the weighing pulley yoke is provided with a weighing pulley; the center of the weighing pulley is provided with a shaft pin sensor which can simultaneously serve as a pulley shaft, between the sensor and the pulley is sleeved with a shaft sleeve II, the side surface of the sensor is provided with a baffle plate, and the baffle plate is fixed on the weighing pulley yoke; a shaft sleeve I is sleeved on the sensor, and the bearing in the weighing pulley is arranged in the shaft sleeve I. The weighing device can weigh accurately, and is not affected by lifting height and the arrangement structure of lifting mechanism when weighing.

Description

technical field [0001] The invention specifically relates to a weighing device structure, in particular to a novel weighing device structure of a shipbuilding gantry crane. Background technique [0002] At this stage, when the shipbuilding gantry crane weighs the hoisted heavy objects, it generally uses a bearing type weighing device or a pivot pin type weighing device for weighing. [0003] Bearing-type weighing device, that is, a bearing-type sensor is installed on the supporting seat of the lifting drum to realize weighing detection. The main parts of this weighing device are bearing cover, bearing seat, sensor and base, and bearing, axle sleeve, through cover and stuffy cover are arranged in the bearing seat to install the reel shaft and use. The reel shaft rotates in the bearing seat, and the load of the reel shaft is transmitted to the bearing seat through the bearing when lifting heavy objects. [0004] Its working principle: When the hoisting mechanism lifts the lo...
