Between, reduce the maintenance cost of oil pumper.
What the purpose of this utility model was realized in：
A kind of belt stress, it is made up of base, rotating shaft, support bar, spring and tensioning wheel, the sectional view of described base
Shape is inverted concave shape, and two sides of concave shape are provided with screwed hole, by screwing bolt in screwed hole, by base
It is fixed on oil pumping unit base；Described rotating shaft is welded on the upper plane of base；The bottom of the support bar is welded on rotating shaft
Together, rotated by axle of direction where rotating shaft, the top connection tensioning wheel of support bar；The bottom connecting bolt of the spring, top
Portion's connection support bar；The tensioning wheel and belt contacts, and rotated around itself.
Above-mentioned belt stress, described spring are extension spring, and described support bar side is provided with annular external part, extension spring
In extended state, the top-hung of extension spring is hooked on annular external part, and bottom is hung on bolt.
Above-mentioned belt stress, the top of the support bar are provided with the cylinder projection in vertical support bar place direction；
Described tensioning wheel is made up of roller, bearing and catch；The roller and bearing outer ring interference fit connect, cylinder it is raised with
Bearing inner race interference fit connection, catch is annular, is fixedly mounted on the both ends of roller.
Beneficial effect：The utility model belt tensioner for oil pumping machine is arranged on oil pumping unit base, roller is pushed down and takes out
Oil machine belt, support bar is held by the pulling force of spring, the pulling force of spring is delivered to roller and compresses belt of oil pumping machine by support bar,
So as to realize the technical purpose of belt tension, be advantageous to improve belt operating efficiency, extend belt usage time, reduce oil pumper
Maintenance cost.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model belt stress.
In figure：1 base, 11 screwed holes, 12 bolts, 2 rotating shafts, 3 support bars, 31 annular external parts, 32 cylinders projection, 4
Spring, 5 tensioning wheels, 51 rollers, 52 bearings, 53 catch, 6 belts.
Embodiment
The utility model embodiment is described in further detail below in conjunction with the accompanying drawings.
The belt stress of the present embodiment, structural representation are as shown in Figure 1.The belt stress is by base 1, rotating shaft 2, branch
Strut 3, spring 4 and tensioning wheel 5 form, and the sectional view of described base 1 is inverted concave shape, two sides of concave shape
Screwed hole 11 is provided with, by screwing bolt 12 in screwed hole 11, base 1 is fixed on oil pumping unit base；Described
Rotating shaft 2 is welded on the upper plane of base 1；The bottom of the support bar 3 welds together with rotating shaft 2, using the place direction of rotating shaft 2 as
Axle rotates, the top connection tensioning wheel 5 of support bar 3；The bottom connecting bolt 12 of the spring 4, top connection support bar 3；Institute
Tensioning wheel 5 and belt contacts are stated, and are rotated around itself.
Above-mentioned belt stress, described spring 4 are extension spring, and the described side of support bar 3 is provided with annular external part 31,
Extension spring is in extended state, and the top-hung of extension spring is hooked on annular external part 31, and bottom is hung on bolt 12.
Above-mentioned belt stress, the top of the support bar 3 are provided with the cylinder projection in the place direction of vertical support bar 3
32；Described tensioning wheel 5 is made up of roller 51, bearing 52 and catch 53；The roller 51 connects with the outer ring of bearing 52 interference fit
Connect, cylinder projection 32 connects with the inner ring of bearing 52 interference fit, and catch 53 is annular, is fixedly mounted on the both ends of roller 51.
The operation principle of the utility model belt stress is：The utility model belt tensioner for oil pumping machine is arranged on
On oil pumping unit base, roller 51 is pushed down the belt 6 of oil pumper, hold support bar 3 by the pulling force of spring 4, support bar 3 is by bullet
The pulling force of spring 4 is delivered to roller 51 and compresses belt 6, so as to realize the technical purpose of the tensioning of belt 6.
Test situation：
In order to verify the technique effect of the utility model belt stress, tested in certain oil field team,：
D2 well groups：On May 26th, 2016 uses the utility model belt stress in 22-11.2 wells
D13 well groups：August uses the utility model belt stress on 25th in 12-9.4 wells within 2016.
Result of the test is：
Raw hide band average life is 15 days, can be extended to 19 days, extended 4 days by using belt stress.
It can also be used 5 days to experiment on 12-10.4 wells using in the belt A 4000 for unloading pine down from well.
Result above shows that the utility model belt tensioner for oil pumping machine realizes the technical purpose of belt tension, improves
Belt operating efficiency, extends belt usage time, reduces the maintenance cost of oil pumper.
