Abstract

The utility model provides a connecting device for weighing sensors. The utility model is composed of fastening screws 2, a joint 3, a seat plate 5, pin roll subassemblies 4, a conical surface washer 6, a spherical washer 7, regulating nuts 8, a hanging rod 9, etc. The utility model has definite flexibility and can be used under the condition of installation positions with low precision. The utility model does not affect the accuracy of the weight checking of a sensor and can protect the sensor from damage. The utility model can be widely used in occasions that a weighing sensor is hung by a material bucket for measuring.

Description

A kind of coupling arrangement of LOAD CELLS

The utility model relates to a kind of coupling arrangement of LOAD CELLS.

The coupling arrangement of LOAD CELLS in the past is a rigidity, but Transfer of Shear, thereby the installation position is equipped with higher geometric position accuracy requirement, otherwise just have shearing, and harmful to LOAD CELLS, also make sensor can not accurately reflect actual measurement weight simultaneously; The coupling arrangement that also useful wire rope is done, though be flexible, elasticity is big, and bounce-back is arranged when weighing, and also makes accurately and timely reading of LOAD CELLS.

The purpose of this utility model be to provide a kind of can be under the precision of general installation site; can guarantee that LOAD CELLS only is subjected to pulling force, is not subjected to shearing; thereby can protect LOAD CELLS to avoid the infringement of shearing, can make LOAD CELLS detect LOAD CELLS coupling arrangement accurately again.

The coupling arrangement of a kind of LOAD CELLS of the utility model has mainly adopted sphere, conical surface contact to pay, also adopted mutual vertically arranged arc surface pin hinge, thereby making is rigidly connected becomes and flexibly connects, do not transmit the shearing that causes owing to the installation site deviation and only transmit pulling force, when weighing, do not have bounce-back simultaneously yet.

The coupling arrangement of a kind of LOAD CELLS that the utility model provides is compared with LOAD CELLS coupling arrangement in the past and is had the following advantages:

1. owing to adopted mutual vertically arranged arc surface pin hinge, making is rigidly connected becomes and flexibly connects, do not transmit the shearing that causes owing to the installation site deviation, thereby can protect LOAD CELLS to avoid the infringement of shearing, LOAD CELLS is detected accurately;

2. owing to adopted the contact of sphere, the conical surface to pay, play self centering effect, make the LOAD CELLS all the time can be vertically stressed, thus not high to the geometric position accuracy requirement of installing;

3. compare with flexible connecting device (being connected) in the past,, when weighing, do not have bounce-back, thereby guarantee accurately and timely reading of LOAD CELLS though the coupling arrangement of the LOAD CELLS that the utility model provides is flexible as wire rope.

Below in conjunction with accompanying drawing the coupling arrangement of a kind of LOAD CELLS of the utility model is done detailed description.

Accompanying drawing is the wiring layout of the coupling arrangement of a kind of LOAD CELLS of the utility model, also is the specification digest accompanying drawing.

This also is embodiment of the present utility model.

1 is LOAD CELLS in the accompanying drawing, and 2 is trip bolt, and 3 is joint, and 4 is Assembly of pin, and 5 is seat board, and 6 is taper faced washer, and 7 is spheric washer, and 8 is setting nut, and 9 is suspension rod, and 10 is hopper.One end of joint 3 screws in the connecting screw of LOAD CELLS 1 upper end and by trip bolt 2 tightenings, the other end of joint 3 is connected with the connecting hole that suspension rod 9 is fastened into them by Assembly of pin 4, the dome arc of joint 3 these end connecting holes is corresponding with the concave arc of Assembly of pin 4, and the dome arc radius of the connecting hole of joint 3 is less than the concave arc radius of Assembly of pin 4, suspension rod 9 passes seat board 5, put taper faced washer 6 and spheric washer 7, by setting nut 8 tightenings; The lower end of LOAD CELLS 1 is to be connected with another set of trip bolt 2, joint 3, Assembly of pin 4, taper faced washer 6, spheric washer 7, setting nut 8 and suspension rod 9 with the same mode in upper end, the axis normal of the axis of the Assembly of pin 4 of different is lower end and the Assembly of pin 4 of upper end, and the seat board 5 of upper end is replaced by the otic placode of the hopper 10 of lower end.

The hole dome arc and Assembly of pin 4 concave arcs of the end that the joint 3 of the coupling arrangement of a kind of LOAD CELLS of the utility model is connected with suspension rod 9 are corresponding, and the dome arc radius of the connecting hole of joint 3 can swing these two web members around the axis rotation of Assembly of pin 4 and the axis direction trace of normal pin shaft assembly 4 less than the concave arc radius of Assembly of pin 4.Because such circular arc pin hinge is connected with two pairs; be connected to the two ends up and down of LOAD CELLS 1; and the axis of two Assembly of pin 4 becomes to be arranged vertically; thereby just be equivalent to a universal joint; make coupling arrangement integral body have certain flexibility; can protect LOAD CELLS to avoid the infringement of shearing, can guarantee that LOAD CELLS detects accurately simultaneously again.

The seat board 5 of the coupling arrangement of a kind of LOAD CELLS of the utility model is fixed on the platform that civil engineering provides, there is lateral error unavoidably in the civil engineering platform, out-of-level after making seat board 5 install, at this moment since contacting of having that taper faced washer 6 and spheric washer 7 constituted pay can self-centering, make suspension rod 9 can keep vertical all the time; Equally, the otic placode of hopper 10 has also used the identical conical surface, sphere contact to pay with the connection of the suspension rod 9 of LOAD CELLS 1 lower end, the deviation that produces is not overlapped and influence LOAD CELLS 1 and vertically be subjected to gravity the making error of hopper 10 and when vibration like this, thereby whole coupling arrangement is not high to the geometric position accuracy requirement of installation.
