Abstract
A short carrier roller type belt running speed detection device is characterized by comprising a carrier roller shaft, bearing blocks, a speed encoder, a lower support and L-shaped fixing plates. One end of the carrier roller shaft is connected with the speed encoder by a coupler, the carrier roller shaft is mounted on the bearing blocks fixed on the lower support, the lower support can be supported on ground by adjustable supporting legs, and two ends of the lower support are connected with the L-shaped fixing plates by bolts and are fixed onto a conveying belt frame. A carrier roller is mounted on the lower side of a lower belt and is lower in stress as no load is arranged on the lower belt the length of the carrier roller is only about 1/4 of the width of the belt, and the carrier roller only contacts with the middle of the wide surface of the belt, so that dead weight of the carrier roller is reduced greatly. Accordingly, the stress condition of the carrier roller is substantially improved, the carrier roller runs stably, and service life of bearings is prolonged.
Description
Technical field:
The utility model is specifically related to a kind of short roller-type belt operating speed detection apparatus.
Background technology:
At present, short roller-type belt operating speed detection apparatus has two kinds: a kind of is that speed encoder+speed wheel (dividing two kinds of woollen goods wheel and iron tyres) is installed in down the belt top and need be fixed on the place that belt frame has crossbeam.Shortcoming: on the belt of operation fast, in case the excessive situation of shake is arranged, the speed wheel takeoffs easily to cause and throws switch, and velocity amplitude and actual value are not inconsistent, and wheel wearing and tearing easily.Second kind of speed encoder+wheel shaft type.Be installed in the belt below.Roller belt has certain bearing force, and roller can not skidded.Shortcoming: carrying roller is installed in and is subjected to the heavily stressed belt below of going up stressed bigger, and carrying roller and belt are isometric, and two is suspended on the frame, and under the effect of alternating force, the carrying roller center is stressed excessive, makes the carrying roller easy deformation, and bearing destroys easily.
Summary of the invention:
It is longer that the utility model aims to provide a kind of service life, detects the short accurately roller-type belt operating speed detection apparatus of data
The realization the technical solution of the utility model is: comprise roller carrier shaft, bearing seat, speed encoder, subiculum support, L type adapter plate, one end of roller carrier shaft is connected with speed encoder by coupler, roller carrier shaft is installed on the bearing seat, bearing seat is fixed on the subiculum support, the subiculum support is supported on the ground by the adjustable supports foot, the two ends of subiculum support are connected with L type adapter plate by bolt, and are fixed on the load-transfer device frame.When roller carrier shaft under being installed in load-transfer device below the belt and belt run-in synchronism, grating rotating during the speed encoder operation, make the staggered on off mode of light path appearance, the photoelectricity part is converted into electric pulse to optical signal and realizes calculating and being sent in the control box, makes the detection data accurate.
Adopt the adjustable support foot that the weight on the speed sensor is supported by ground, make carrying roller move more balance, alleviated the pulling force of device simultaneously, make it regulate height more easily bolt on the frame.
Speed sensor adopts L type adapter plate to be connected with the load-transfer device frame, and is easier for installation.
Carrying roller of the present utility model is installed in down the belt below, because belt zero load down, carrying roller is stressed little; And carrying roller length only be belt wide about 1/4, only the centre portion with wide of belt contacts, carrying roller deadweight alleviates greatly.For above-mentioned reasons, make that the force-bearing situation on the carrying roller is greatly improved, carrying roller operates steadily, and bearing increases service life.

The specific embodiment:
The specific embodiment of the present utility model is not limited to following embodiment, can adopt different embodiment as the case may be.
Embodiment: Fig. 1, Fig. 2, shown in Figure 3, present embodiment comprises roller carrier shaft 12, bearing seat 1, speed encoder 4, subiculum support 24, L type adapter plate 22, one end of roller carrier shaft 12 is connected with speed encoder 4 by coupler, roller carrier shaft 12 is installed on the bearing seat 1, bearing seat 1 is fixed on the subiculum support 24, subiculum support 24 is supported on the ground by adjustable supports 25 foots, and subiculum support 24 two ends are connected with L type adapter plate 22 by bolt, and are fixed on the load-transfer device frame.
Speed encoder adopts the E6B2-CWZ3E-360P/R type.
