Description
Technical field
The utility model relates to a kind of testers, more particularly, to a kind of modified attachment coefficient tester.
Background technique
The ratio of attachment coefficient, that is, adhesive force and bus or train route normal pressure.
Tester rack rear is mainly fixed on a fixed object with cable type chain by test attachment coefficient before
On, for chain fixed form in braking, rack meeting front and back play keeps braking forces measuring inaccurate, repeatability is bad, and there are also improved
Space.
Utility model content
The purpose of the utility model is to provide one kind, and there is effective realization rack to be fixed, and improves braking forces measuring
The modified attachment coefficient tester of the effect of accuracy.
The above-mentioned purpose of utility model of the utility model has the technical scheme that
A kind of modified attachment coefficient tester, regulating mechanism including weighted plate, above weighted plate are connected to tune
The frame in mechanism is saved, and organic frame is installed on frame, and rack two sides are provided with handwheel and are connected to handwheel with fixed
The support rod of position rack.
By using above-mentioned technical proposal, effectively rack can be carried out by the setting of weighted plate, regulating mechanism, frame
Support can position rack by handwheel and the support rod setting of rack two sides.
The utility model is further arranged to: modified attachment coefficient tester further include be disposed in proximity to handwheel side with
Arrestment mechanism for located hand wheel.
By using above-mentioned technical proposal, handwheel can be determined when needed by the setting of arrestment mechanism
Position, avoids handwheel from moving under the effect of external force.
The utility model is further arranged to: the arrestment mechanism includes cylinder and is connected to cylinder to be controlled by cylinder
It is moved to the locating rod that handwheel is positioned.
By using above-mentioned technical proposal, it is effectively increased when needed by the setting of cylinder and locating rod
To the locating effect of handwheel.
The utility model is further arranged to: further including the fixed block for being fixedly connected on cylinder.
By using above-mentioned technical proposal, the positioning to locating rod is effectively realized by the setting of fixed block, to mention
The high stability of locating rod when in use.
The utility model is further arranged to: being equipped with aviation socket on the frame and is positioned by screw.
By using above-mentioned technical proposal, by aviation socket be provided with efficacious prescriptions electrical equipment needing electricity consumption
When can be timely electric.
The utility model is further arranged to: the quantity of screw is surroundings that are several and being distributed in aviation socket.
Aviation socket has been effectively ensured since screw is distributed in the surrounding of aviation socket by using above-mentioned technical proposal
Stability when in use.
Detailed description of the invention
Fig. 1 is a kind of modified attachment coefficient tester structural schematic diagram of the utility model.
In figure, 1, weighted plate；2, regulating mechanism；3, frame；4, aviation socket；5, rack；6, handwheel；11, support rod；7,
Arrestment mechanism；8, cylinder；9, locating rod；10, fixed block.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Referring to Fig.1, be a kind of modified attachment coefficient tester disclosed by the utility model, including weighted plate 1, be located at plus
The regulating mechanism 2 of 1 top of weight plate, the frame 3 being connected on regulating mechanism 2, and organic frame 5 is installed on the frame 3, and in rack
5 two sides are provided with handwheel 6 and are connected to handwheel 6 with the support rod 11 of positioning frame 5.
Modified attachment coefficient tester further includes being disposed in proximity to 6 side of handwheel with the brake for located hand wheel 6
Structure 7, the arrestment mechanism 7 are included cylinder 8 and are connected to cylinder 8 and are determined be controlled by that cylinder 8 is moved to that handwheel 6 positioned
Position bar 9.
To improve the stability of cylinder 8 when in use, modified attachment coefficient tester further includes being fixedly connected on cylinder 8
Fixed block 10.
It charges, aviation socket 4 is installed on frame 3 and is determined by screw when needed for the convenience of the user
Position, the quantity of screw are surroundings that are several and being distributed in aviation socket 4.
The implementation principle of the present embodiment are as follows:
Two racks, 5 balanced support wheel after rack 5 is changed to two handwheels 6 and rotates support rods 11, under support rod 11
There is a plane of constraint in face, and after 5 Level tune of rack is good, 11 plane of constraint of support rod is fixed on the iron plate of one piece of rectangle,
The bottom surface of iron plate glues sand and is allowed to have higher coefficient of friction with ground,
When detection, put on iron plate twice or so more than or equal to analysis of wheel vertical normal pressure weight object (or station
Upper one or two of people), guarantee that the frictional force on iron plate and ground is greater than the frictional force of wheel and roller, rack 5 is just in braking in this way
Will not front and back play, normal pressure remains unchanged, and PVvalue testing is accurate, reproducible, easy to operate.It additionally can be by two
6 support rod 11 of handwheel changes the outfit into two adjustable bearing split bearing roller supports as supporting-point.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
