Abstract
The utility model discloses a vernier caliper used for measuring height of a Marshall test piece, and belongs to a vernier caliper with scales and used for direct reading. A vernier caliper body is composed of a main ruler and a slidable vernier attaching to the main ruler. A pair of outer ring contacts are arranged at the lower ends of the main ruler and the vernier. The outer ring contacts can bypass a Marshall test mold and contact a surface of a Marshall test piece, and thus the height of the Marshall test piece can be measured directly. When the measuring method through the provided vernier caliper is compared with a traditional measuring method for a Marshall test piece without mold release, the outer ring contacts can bypass a Marshall test mold and contact a surface of a Marshall test piece, and the height of the Marshall test piece without mold release can be measured directly. Workload is lowered greatly, and test errors are decreased.
Description
Technical field
The utility model relates to a kind of for measuring the vernier caliper of marshal piece height.
Background technology
In the existing asphalt standard of China, lot of experiments all needs moulding marshal piece, first needs to measure its height after marshal piece moulding.Measure at present demoulding marshal piece height not and be all and adopt the front end pit gauge part of vernier caliper to measure respectively the difference in height on test specimen surface and die trial top, and then highly deduct the poor sum of both heights with die trial.Not only complex operation of this kind of measuring method, and twice measurement increased test error.
Utility model content
The purpose of this utility model is to overcome above-mentioned technical disadvantages, provides a kind of simple for measuring the vernier caliper of marshal piece height, and this vernier caliper can be measured not demoulding marshal piece height convenient, accurately.
For achieving the above object, the utility model adopts following technical scheme: comprise vernier caliper body; On vernier caliper body, be provided with the outer shroud contact that can directly contact with the marshal piece surface being arranged in Marshall die trial.
Described vernier caliper body can be made up of along the vernier of main scale slip with being arranged on main scale main scale, and outer shroud contact is arranged on respectively on main scale and vernier.
The length of described main scale is 200mm.
Described main scale, vernier and outer shroud contact are made by high-carbon steel.
Described outer shroud contact comprises feeler lever part and U-shaped contact part; One end of feeler lever part is fixedly connected with main scale or vernier respectively, the other end of feeler lever part is fixedly connected with a side end of U-shaped contact part, the opening that is arranged on respectively two U-shaped contact parts on main scale and vernier is oppositely arranged, and the end face of opening with feeler lever part to flushing; The end side of U-shaped contact part is as measuring contact.
When the contact of described U-shaped contact part is interlocked mutually, vernier caliper reading is zero; When the contact of U-shaped contact part is in contact with one another through Marshall die trial and marshal piece, the height that reading is marshal piece.
Compared with prior art, the utlity model has following beneficial effect:
Traditional not demoulding marshal piece measuring method is to adopt vernier caliper front end pit gauge to measure the difference in height on test specimen surface and die trial top, and then highly deducts the poor sum of both heights with die trial and obtain.The utility model is provided with unique outer shroud contact, and outer shroud contact can walk around die trial and marshal piece is in contact with one another, and directly can measure height of specimen, has greatly simplified workload compared to traditional measuring method, has reduced test error; Simultaneously, because there is depression points on marshal piece surface, traditional measurement method is State selective measurements point by rule of thumb, the contact of point between point, easily cause measurement data and True Data to differ larger, and marshal piece height measure the outer shroud contact of special vernier caliper have long-pending compared with large contact surface, can forming surface and the contacting of face, without the problem of consideration State selective measurements point.
Further, the utility model not only can convenient, accurately be measured not demoulding marshal piece height, and can serve as common calliper use.
Further, the utility model main scale length is 200mm, completely enough measures large Marshall sample height.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The schematic diagram that Fig. 2 is the utility model in the time measuring demoulding marshal piece not.
Wherein, 1 is vernier caliper body; 2 is main scale; 3 is vernier; , 4 is contact part; 5 is marshal piece; 6 is Marshall die trial; 7 is feeler lever part.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1, the utility model comprises vernier caliper body 1; On vernier caliper body 1, be provided with the outer shroud contact that can directly contact with marshal piece 5 surfaces that are arranged in Marshall die trial 6, vernier caliper body 1 can be made up of along the vernier 3 of main scale slip with being arranged on main scale 2 main scale 2, outer shroud contact is arranged on respectively on main scale 2 and vernier 3, and the length of main scale 2 is 200mm; Vernier caliper body 1 and outer shroud contact are made by high-carbon steel.Outer shroud contact comprises feeler lever part 7 and U-shaped contact part 4; One end of feeler lever part 7 is fixedly connected with main scale 2 or vernier 3 respectively, the other end of feeler lever part 7 is fixedly connected with a side end of U-shaped contact part 4, the opening that is arranged on respectively two U-shaped contact parts 4 on main scale 2 and vernier 3 is oppositely arranged, and the end face of opening with feeler lever part 7 to flushing; The end side of U-shaped contact part 4 is as measuring contact, and when the contact of U-shaped contact part 4 is interlocked mutually, vernier caliper reading is zero; When the contact of U-shaped contact part 4 is in contact with one another through Marshall die trial 6 and marshal piece 5, reading is the height of marshal piece 5.
The course of work of the present utility model is:
As shown in Figure 1, in the time of the mutual interlock of outer shroud contact, vernier caliper reading is zero; As shown in Figure 2,4 outer shroud contacts can walk around Marshall die trial and marshal piece is in contact with one another, and can directly measure not demoulding marshal piece height, and now vernier caliper reading is marshal piece height.
