Detailed description of the invention
The exemplary embodiments embodying feature & benefits of the present invention will describe in detail in the following description.Be understood that the present invention can have various changes in different embodiments, it neither departs from the scope of the present invention, and explanation wherein and accompanying drawing are the use when explain in itself, and is not used to limit the present invention.
In order to effectively or better solve, the installation existed in prior art is numerous and diverse, Heavy Weight, the troublesome technical matters of maintenance, the present invention is the principle of work according to offsetting steel rope deflection generation power all around, between four electronic scaless 15, add two divider assemblies 91,92, substitute three girt limiting devices 16,17,18 of prior art completely.The feature that the present invention weighs divider be simple and compact for structure, practical, inexpensive, easy to maintenance, lightweight, be easy to check.
The hoisting crane of the embodiment of the present invention, has the electronic weighing system of the embodiment of the present invention, also has the weighing divider of the embodiment of the present invention.The electronic weighing system of the embodiment of the present invention, then have the weighing divider of the embodiment of the present invention.And the electronic weighing system of the embodiment of the present invention comprises the weighing divider 91,92 of electronic scales 15 and the embodiment of the present invention.
Below the weighing divider of the embodiment of the present invention is specifically introduced, as shown in Fig. 3, Fig. 8 and Fig. 9, the weighing divider of the embodiment of the present invention is made up of a pair divider assembly 91,92, it is arranged between four electronic scaless 15, as shown in Figure 3, divide equally distribution in the lateral direction, namely a pair divider assembly 91,92 is roughly by the trisection of distance between left and right of electronic scales 15, and in the longitudinal direction, under the first deployment scenarios as shown in Figure 8, the fore-and-aft cearance of divider assembly 91,92 roughly decile electronic scales 15, as shown in Figure 4.
Below for divider assembly 91, first introduce single divider assembly, and then introduce the positioned opposite of two divider assemblies 91,92.
As shown in Figure 5, weigh assembly 91 and comprise interior block piece 5, outer block piece 6, bolt 3, bolt 4, nut 7 and nut 8.
As shown in Figure 7, interior block piece 5, comprises vertical connected horizontal part 52 and vertical component effect 51; Outer block piece 6 comprises horizontal part 62 and vertical component effect 61, and wherein horizontal part 52 is parallel with horizontal part 62, and vertical component effect 61 is parallel with vertical component effect 51; Here, angle steel is the extraordinary material of block piece 5 and outer block piece 6 in being formed, but also can form interior block piece 5 and outer block piece 6 with two block plate vertical weldings.
As shown in Figure 7, bolt 3, bolt 4 are adjustment parts, the head of bolt 3 is resisted against the outside face of horizontal part 52, and be spirally connected with the negative thread in the tapped bore offered on horizontal part 62, to adjust gap, the front and back h between horizontal part 52 and horizontal part 62, the object of gap h before and after adjustment, is the outside face keeping the head of bolt 3 to be resisted against horizontal part 52, offsets the power of fore-and-aft direction with actv.; Interior block piece 5 mentioned here and outer block piece 6 are that in being, the side of 270 degree of angles is outward with 90 of angle steel degree of angle sides.Identical, the head of bolt 4 is resisted against the outside face of vertical component effect 51, and be bolted in the negative thread of the tapped bore that vertical component effect 61 is offered, to adjust the gap, left and right between vertical component effect 51 and vertical component effect 61, with the outside face keeping the head of bolt 3 to be resisted against vertical component effect 51, offset the power of left and right directions with actv..Here, gap, front and back h is such as 10mm, and gap, left and right is also such as 10mm, but gap, front and back h and gap, left and right do not require inevitable equal.
In order to ensure precision, the bolt head processing of bolt 3,4 is flat, and when tightening, the head of bolt 3,4 holds out against the outside face of horizontal part 52 and vertical component effect 51 respectively.In the present invention, bolt 3 and bolt 4 also can either be fixedly connected on outer block piece 6 with other, and the adjustment part that can adjust again gap between interior block piece 5 and outer block piece 6 replaces.
As shown in Figure 7, bolt 3,4 is respectively equipped with nut 7,8, nut 7,8 is tightened against the outside face of horizontal part 52 and vertical component effect 51 respectively.The effect of nut 7,8 prevents bolt 3,4 from loosening.Weighing divider of the present invention, nut 7,8 also can be welded on the outside face of horizontal part 62 and vertical component effect 61, and at this moment the tapped bore of horizontal part 62 and vertical component effect 61 just can replace with unthreaded hole, like this can simplified processing process.
As shown in Figure 3, when connecting, can be that the top of interior block piece 5 is fixedly connected with (such as welding) in the assembly pulley bearing 11 of lifting mechanism, the bottom of outer block piece 6 be fixedly connected with (such as welding) plane 12 on trolley frame.Also can be the assembly pulley bearing 11 that the top of outer block piece 6 is fixedly connected on lifting mechanism, and the bottom of interior block piece 5 be fixedly connected on plane 12 on trolley frame.
Introducing the positioned opposite of two divider assemblies 91,92 below again, both can be left and right mirror-image arrangement as shown in Figure 8, also can be rotational symmetry layout as shown in Figure 9.When left and right mirror-image arrangement as described in Figure 8, the horizontal part 52,62 of a pair divider assembly 91,92 is all coplanar relation, vertical component effect 51,61 is then parallel relation, and at this moment, the left view of the divider assembly 91 shown in Fig. 6 is also the front view of divider assembly 92 simultaneously.When rotational symmetry is as described in Figure 9 arranged, be equivalent to the mirror image before and after being tried again by the divider assembly 92 in Fig. 8, at this moment, the horizontal part 52,62 of a pair divider assembly 91,92 is all parallel relation, and vertical component effect 51,61 is also parallel relation.At this moment, the left view of the divider assembly 91 shown in Fig. 6 is also the right elevation of divider assembly 92 simultaneously, and the front view of the shown divider assembly 91 shown in Fig. 5 is also the back view of divider assembly 92 simultaneously.Further, its axisymmetric axis of symmetry, can be the geometric centre by plane on trolley frame 12 and the straight line vertical with plane on trolley frame 12.
The weighing divider of the embodiment of the present invention, not only instead of the girt limiting device 16,17,18 of prior art completely, and low price, compact conformation.The present invention has good applicability for the top sheave group 20 that hoisting capacity is little for the structure that trolley frame cannot be arranged.
Technical scheme of the present invention is disclosed as above by preferred embodiment.The change that those skilled in the art do when should recognize the scope and spirit of the present invention disclosed in the claim do not departed from appended by the present invention and retouching, within the protection domain all belonging to claim of the present invention.
