A kind of belted electronic balance scale rack device
Technical field
The utility model relates to a kind of belted electronic balance scale rack device, is particularly useful for the feed Weighing of the continuous convey materials of belt conveyor.
Background technology
At present, be used for the belted electronic balance of belt conveyor material continuous-feeding weighing, simple lever, double lever, multiple version such as floated are arranged; Wherein floated structure has forms such as many carrying rollers and single mount roller again, the form middle idler roller of the single mount roller that two LOAD CELLS support is generally the formula of rigidly fixing with being connected of LOAD CELLS, this version is because steel construction both sides parallelism error forms certain structurally internal stress, sometimes this internal stress can't finely discharge, be easy to generate the location, thereby influenced accuracy and long-time stability that belt conveyer scale finally measures the result.
Summary of the invention
Technical matters: the purpose of this utility model is the weak point that overcomes in the prior art, and a kind of compact conformation is provided, and internal stress free, does not have the location, and Installation and Debugging are simply easy, the belted electronic balance scale rack device that measuring accuracy is high.
Technical scheme: belted electronic balance scale rack device of the present utility model, comprise the parallel roll axle or the groove profile carrier roller support that are located on the conveyor frame, the both sides of conveyor frame are respectively equipped with LOAD CELLS, the two ends of described parallel roll axle or groove profile carrier roller support are respectively equipped with a sphere oscillating bearing, the sphere oscillating bearing is fixed on LOAD CELLS one end through set nut, the other end of LOAD CELLS is provided with through the fixing back-up block of set bolt, and back-up block is fixed on the conveyor frame through attachment bolt.
Be provided with the spill pad between described sphere oscillating bearing and the LOAD CELLS; Described back-up block is provided with caging bolt.
Beneficial effect: adopt be installed in above the conveyor frame about two steel construction back-up blocks, and by the LOAD CELLS on two steel construction back-up blocks about being located at respectively, be provided with caging bolt below each LOAD CELLS back-up block, the sphere oscillating bearing respectively is equipped with at LOAD CELLS cylindrical end and parallel roll axle or flute profile roller rack two ends, it is on the cylindrical cantilevered LOAD CELLS that the protruding spherical surface body endoporus of sphere oscillating bearing directly is associated in the end, utilize set nut oscillating bearing to be locked at an end of LOAD CELLS, thread connection parallel roll axle or groove profile carrier roller support on the sphere oscillating bearing concave spherical surface body, because oscillating bearing is recessed, can free universal rotation between the protruding spherical surface body, thereby eliminate parallel roll axle or the not parallel structurally internal stress that causes in groove profile carrier roller support two ends and band conveyor frame both sides, the stress that makes LOAD CELLS bear convey materials load is in optimum condition.Be best suited for the feed Weighing of the continuous convey materials of belt conveyor, it is simple in structure, and the adaptive zone wide region is big, LOAD CELLS did not have the location, and Installation and Debugging are simply easy, and measuring accuracy is accurate, maintenance workload is few, and long service life has practicality widely.

Among the figure: 1-parallel roll axle, 2-groove profile carrier roller support, 3-sphere oscillating bearing, 4-LOAD CELLS, 5-spill pad, 6-set nut, 7-set bolt, 8-caging bolt, 9-back-up block, 10-attachment bolt, 11-conveyor frame.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Embodiment one, belted electronic balance scale rack device as shown in Figure 1 mainly are made up of parallel roll axle 1, sphere oscillating bearing 3, LOAD CELLS 4, spill pad 5, set nut 6, set bolt 7, caging bolt 8, back-up block 9, attachment bolt 10.Wherein back-up block 9 is two, by about be fixed on above the conveyor frame 11 by attachment bolt 10 respectively, one end of LOAD CELLS 4 is fixed on the back-up block 9 by set bolt 7, the cylinder axis of the other end of LOAD CELLS 4 connects the protruding spherical surface body endoporus of sphere oscillating bearing 3, the cylinder axis end of LOAD CELLS 4 is threaded, set nut 6 is locked at LOAD CELLS 4 ends with sphere oscillating bearing 3, thread connection parallel roll axle 1 on the concave spherical surface body of sphere oscillating bearing 3, because the sphere oscillating bearing is recessed, can free universal rotation between the protruding spherical surface body, thereby eliminate parallel roll axle 1 two ends and the not parallel structurally internal stress that causes in band conveyor frame 11 both sides, the location of crossing that the error in mounting position of two LOAD CELLS back-up blocks 9 on conveyor frame 11 brings for LOAD CELLS 4 about can eliminating influences; Caging bolt 8 on the back-up block 9 can be to LOAD CELLS 4 overload protection in addition.Shown in Figure 2, spill pad 5 is contained between sphere oscillating bearing 3 and the LOAD CELLS 4, and the number of degrees that the concave spherical surface body that its concave surface limits sphere oscillating bearings 3 towards sphere oscillating bearing 3 turns to limit the horizontal force that belt movement brings simultaneously.Parallel roll scale frame respectively is equipped with the sphere oscillating bearing on its parallel roll axle two ends,
Embodiment two, basic identical with embodiment one, belted electronic balance scale rack device as shown in Figure 3, mainly form, omit with embodiment one same section by groove profile carrier roller support 2, sphere oscillating bearing 3, LOAD CELLS 4, spill pad 5, set nut 6, set bolt 7, caging bolt 8, back-up block 9, attachment bolt 10.Flute profile carrying roller scale frame respectively is equipped with the sphere oscillating bearing on its flute profile roller rack two ends, it is on the cylindrical cantilevered LOAD CELLS that two sphere oscillating bearing endoporus directly are associated in the end respectively, by set nut 6 oscillating bearing is locked at LOAD CELLS 4 one ends, the other end of LOAD CELLS 4 is associated on the back-up block 9 by set bolt 7, and back-up block 9 is fixed on the band conveyor by attachment bolt 10; Back-up block 9 is provided with the caging bolt 8 that is used for the LOAD CELLS overload protection.
