Description
Technical field
The present invention relates to a kind of survey tool in rolling stock field more particularly to a kind of abrasion residual thickness measurements of brake shoe
Ruler.
Background technology
With the utilization and development of domestic railway freight-car, the cost of car operation increasingly obtains the concern of insider.
Brake shoe is typical wear part, studies its workmanship for contributing to understand brake shoe in the abrasion situation during, also can
The replacing construction of brake shoe is more reasonably determined so as to reduce brake shoe replacement amount.Brake shoe abrasion loss has directly with vehicle distance travelled
Relation is connect, by the detection that brake shoe same position thickness before and after certain distance is run to vehicle, you can the thickness for obtaining brake shoe becomes
Amounts of thickness variation under change amount and unit mileage.However, iron tyre lorry brake shoe shape is complex, and specified point must be examined
It surveys, so needing the brake shoe Thickness sensitivity amount instrument of design specialized.
The content of the invention
In view of the above-mentioned problems, the object of the present invention is to provide it is a kind of can be to two positions in end, middle part of brake shoe at
The brake shoe abrasion residual thickness measuring scale of thickness.
To achieve the above object, the present invention uses following technical scheme：A kind of brake shoe wears away residual thickness measuring scale, special
Sign is：It includes a reference arm, a sliding slot arm, a sliding seat, a vernier seat and a vernier scale；The reference arm includes a master
Support arm and be in the upper arm, middle arm and the underarm that are wholely set with the main support arm；It is fixed to be fixedly connected in the bottom of the upper arm on one
Position leg；It is fixedly connected in the front end of the underarm and positions leg；The front side of the forward terminal of the middle arm and the lower positioning leg
Face is on watt back of the body circular arc of brake shoe；The sliding slot arm is included in the transverse arm and an oblique arm being wholely set；The transverse arm
Rear end is fixedly connected by a cushion block with the front end of the upper arm；Open up an arc groove on the oblique arm, the arc groove with
Watt back of the body circular arc of brake shoe is concentric；The sliding seat is slidably connected by positioning pin and the arc groove；The vernier seat, which is fixed, to be connected
It is connected on the one side of the sliding seat；The vernier scale is arranged on along watt radially sliding for circular arc of the back of the body for brake shoe in the vernier seat.
The end that leg and lower positioning leg are positioned on described sets a block simultaneously.
Reinforcing rib is provided between the lower positioning leg and the reference arm underarm.
The present invention has the following advantages due to taking above technical scheme：1st, the present invention due to set a reference arm and
One sliding slot arm, and sliding slot arm is slidably connected a sliding seat by an arc groove, is slidably connected on sliding seat by a vernier seat
One vernier scale, therefore can be stuck in by reference arm on brake shoe, while the thickness of brake shoe is measured using vernier scale, work as cunning
When dynamic seat is in the upper end extreme position of arc groove, vernier scale can measure the thickness on brake shoe top；When sliding seat is in arc
During the lower end extreme position of slot, vernier scale can measure the thickness in the middle part of brake shoe.2nd, the present invention is due in upper positioning leg and lower fixed
The end of position leg sets a block simultaneously, therefore when reference arm is stuck on brake shoe, it is not easy to it is slipped from brake shoe.3rd, this hair
It is bright due to it is lower positioning leg and reference arm underarm between be provided with reinforcing rib, have the preferable rigidity of structure, firm and durable.
4th, the configuration of the present invention is simple, easy to use, and high certainty of measurement, through actual verification precision up to 0.1mm.

Specific embodiment
The present invention is described in detail below with reference to the accompanying drawings and embodiments.
As described in Fig. 1~4, the present invention includes a reference arm 1, a sliding slot arm 2, a sliding seat 3, a vernier seat 4 and a trip
Scale 5.
As shown in figure 5, reference arm 1 include a main support arm 11 and be wholely set with main support arm 11 upper arm 12, middle arm 13 and
Underarm 14.Positioning leg 16 on one is fixedly connected in the bottom of upper arm 12.Positioning leg 17 is fixedly connected in the front end of underarm 14.
The leading flank of the forward terminal of middle arm 13 and lower positioning leg 17 is on watt back of the body circular arc of brake shoe.
As shown in fig. 6, sliding slot arm 2 is included in the transverse arm 21 and an oblique arm 22 being wholely set.The rear end of transverse arm 21 passes through
One cushion block 6 is fixedly connected with the front end of 1 upper arm 12 of reference arm.An arc groove 23, arc groove 23 and lock are offered on oblique arm 22
Watt watt the back of the body circular arc it is concentric.
As shown in Figure 1, sliding seat 3 is slidably connected by two positioning pins 7 with arc groove 23.Vernier seat 4 is fixedly connected on cunning
The one side of dynamic seat 3.Vernier scale 5 is slidably arranged in along a watt radial direction for back of the body circular arc in vernier seat 3.
In the use of the present invention, reference arm 1 is stuck on brake shoe, wherein, the bottom of upper positioning leg 16 rides over the top of brake shoe
On facial planes, the front end of the front end of middle arm 13 and lower positioning leg 17 is against watt back of brake shoe, and adjustment sliding seat 3 is in arc groove
Position in 23, while measured using vernier scale 5.When sliding seat 3 is in the upper end extreme position of arc groove 23, vernier
Ruler 5 can be used for measuring the thickness on brake shoe top；When sliding seat 3 is in the lower end extreme position of arc groove 23, vernier scale 5 can
With the thickness for being used for measuring in the middle part of brake shoe.
In the above-described embodiments, can one block 8 be set simultaneously in the end of upper positioning leg 16 and lower positioning leg 17, so
When reference arm 1 is stuck on brake shoe, block 8 can prevent the present invention from being slipped from brake shoe.
In the above-described embodiments, reinforcing rib 9 can be added between lower positioning 1 underarm 14 of leg 17 and reference arm, to increase
The stiffness of structure.
The present invention is only illustrated with above-described embodiment, and structure, installation position and its connection of each component are all can have
Changed.On the basis of technical solution of the present invention, improvement or equivalent that all principles according to the present invention carry out individual part
Conversion, should not exclude outside protection scope of the present invention.
