Abstract
The utility model relates to an electronic scale of a bridge crane, comprising a mounting base, a fixed pulley group and a fixed pulley shaft; the scale is characterized in that: a weighting sensor is arranged at the supporting position at the two ends below the fixed pulley shaft, a lining sleeve is sheathed at the loading position of the fixed pulley shaft and is fixed by locking nuts; a protective bracket is arranged on the fixed pulley shaft and is connected with the weighting sensor. A loading point of the weighting sensor adopts a double-arc loading structure and the arcs are vertical to each other. The electronic scale has the characteristics that the structure is simple, the installation, processing and maintenance is convenient, the quantify precision is high, and the scale is safe and reliable and the like.
Description
Technical field
The utility model relates to a kind of electronic scales erecting device, relates in particular to the electronic scales erecting device of the crane in bridge type in a kind of large-tonnage equipment hoisting field.
Background technology
Raising along with production technology and enterprise management level, the user is also more and more higher to the operating needs of crane in bridge type electronic scales, constantly the accuracy of crane in bridge type electronic scales is had higher requirement, this has just also proposed more and more higher requirement to design, all takes into account at aspects such as synthesis precision, reliability of service, retrofit work amount, improvement project quality, improvement expenses and maintainabilitys.
The crane in bridge type electronic scales is equipped with several different methods.The electronic scales installation method of various different modes is applicable to different types of crane in bridge type version.Below trolley platform, the LOAD CELLS installation site is risen to electronic scales mounting means on the trolley platform for fixed pulley axis by force transmission shaft, power transmission side plate; Have whole trolley platform is lifted, under trolley platform LOAD CELLS is installed, the mode that is equivalent to do a platform scale is installed electronic scales or the like.For the electronic scales mounting means of large-tonnage crane in bridge type, as the crane in bridge type more than the 200t, be used for the crane in bridge type electronic scales of fixed pulley axis more than the travelling car platform and install, prior art does not also have a kind of good terms of settlement.
Summary of the invention
Main purpose of the present utility model is: develop a kind of simple in structure, convenient for installation and maintenance, the weighing precision height, dependable performance is applicable to the crane in bridge type electronic scales erecting device of fixed pulley axis more than the travelling car platform.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of crane in bridge type electronic scales erecting device, has mounting seat, fixed pulley group and fixed pulley axis, it is characterized in that: the bearing position at two ends is equipped with LOAD CELLS under fixed pulley axis, be with lining in fixed pulley axis loading place, described lining is fixed by jam nut, is provided with to protect frame on fixed pulley axis, and the described frame that protects links to each other with LOAD CELLS.LOAD CELLS is fixed on the base plate, and base plate is fixed with mounting seat again, makes it form an integral body.
The technical solution of the utility model can also be further perfect,
As preferably,
The load(ing) point of LOAD CELLS adopts vertical each other two arc loading structures.
Therefore, the beneficial effects of the utility model are: the two ends of fixed pulley axis are equipped with jam nut, are provided with on fixed pulley axis and protect frame, protect frame and are connected with sensor by lining, improved the compactedness of structure and effectively prevent the axle play; The upper surface of sensor adopts vertical each other two arc loading structures, i.e. " fish the back of the body formula " loading structure, can make between force transmission shaft and the sensor by the contact of line contact height, can not cause to load the back, guarantee the high precision and the stability of electronic scales to sensor outside drift condition because level between the sensor changes.
Therefore, the utlity model has simple in structure, installation, processing, easy to maintenance, weighing precision height, characteristics such as safe and reliable.
Description of drawings
Accompanying drawing 1 is a kind of structural front view of the present utility model;
Accompanying drawing 2 is lateral plans of Fig. 1.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Electronic scales erecting device as Fig. 1 a kind of crane in bridge type shown in Figure 2, fixed pulley group 8 is installed on the fixed pulley axis 4, two ends are equipped with sensor 3 under fixed pulley axis, fixed pulley axis loading place is with lining 6, two places are fixing by jam nut 7, be provided with above and protect frame 5, protect frame and sensor and the base plate 2 that is installed in below the sensor links to each other, support by sensor mounting seat 1.The horizontal looseness of fixed pulley axis 4, the load(ing) point of fixed pulley axis and LOAD CELLS is changed, thereby cause the reduction of weighing precision, adopt following method to guarantee the immobilizing of load(ing) point position of fixed pulley axis 4 and LOAD CELLS 3 for this reason, the one, the load(ing) point of LOAD CELLS 3 adopts " fish back of the body formula " loading structure, promptly vertical each other two arc loading structures are adopted on the surface, can make between fixed pulley axis 4 and the sensor load(ing) point by the contact of line contact height; The 2nd, on fixed pulley axis 4, install one and protect frame 5, protect frame and be fixed on LOAD CELLS 3 loading heads by jam nut 7, block fixed pulley axis 4.Prevent the horizontal looseness of fixed pulley axis by said method, guarantee that the weighing precision of electronic scales does not influence because of the horizontal looseness of fixed pulley axis.
The utility model is applicable to the electronic scales installation of large bridge cranes such as metallurgy, harbour.
