Description

Technical Field

[0001] The utility model relates to the technical field of core sample measurement auxiliary equipment, in particular to a device for measuring the appearance size of a core sample. Background Art

[0002] With the development of civil engineering, engineering coring testing is becoming more and more common. Usually, a core sample specimen is drilled from a concrete structure. The specimen is cylindrical. In order to test the compressive strength after coring, there are high requirements for the size of the drilled core sample. Therefore, the appearance of the core sample needs to be inspected. Any deviation will cause inaccurate test.

[0003] In the existing technology, during the coring inspection process of concrete structures in the civil engineering field, although the diameter, height and verticality of core sample specimens can be measured by various rulers, most of the measurements are done manually one by one. The measurement efficiency is low, and continuous single measurements are prone to introduce errors. The fatigue and irritability caused by repetitive work of the workers lead to inaccurate measurements, which leads to problems in subsequent tests. Utility Model Content

[0009] Preferably, a through slot is provided in the middle of the transverse scale, and the lower swing piece is located in the through slot.

[0010] Through the above technical solution, the verticality detection component is integrated into the support block, which saves space and can move with the support block. The verticality can be measured while measuring the diameter. Only by observing the position of the upper pointer on the protractor can the verticality of the object be quickly understood. Multiple measurement tasks can be completed in a short time while ensuring the accuracy and reliability of the measurement results.

[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention is further described in detail below with reference to the accompanying drawings.

[0028] A device for measuring the external dimensions of a core sample, such as Figure 1-6As shown, it includes a supporting base plate 1, a supporting column 2 and an adjustable horizontal measuring ruler 3. The supporting base plate 1 is detachably mounted with the supporting column 2. The adjustable horizontal measuring ruler 3 is slidably connected to the supporting column 2 through a slider 5. A level 4 is provided on the supporting base plate 1. Adjustable feet 8 are installed at the four corners of the supporting base plate 1. The adjusting feet 8 are bolted to the supporting base plate 1 and can be adjusted at any time. When used with the level 4, it can ensure that the entire device is in a horizontal state, thereby improving the accuracy of the measurement. The supporting column 2 and the adjustable horizontal measuring ruler 3 are both marked with scales. The adjustable horizontal measuring ruler 3 is provided with The verticality detection component 32 completes the intuitive detection of the diameter and verticality of the core sample through the adjustable horizontal measuring ruler 3 and the verticality detection component 32 thereon, and detects the height of the core sample in conjunction with the scale on the support column 2. The support column 2 is square as a whole, and has a threaded protrusion at the bottom, which is bolted to the support base plate 1. A capping block 6 is detachably installed on the support column 2. The capping block 6 is mushroom-shaped and bolted to the top surface of the support column 2, which can prevent the adjustable horizontal measuring ruler 3 from falling out due to the worker's failure to control the force during adjustment. All components of the device are in a detachable state for easy storage and transportation.

[0029] The adjustable transverse measuring ruler 3 includes a transverse scale 31, a support block 33 and a lap rod 34. The lap rod 34 is installed in the support block 33. The support block 33 and the lap rod 34 are slidably installed on the transverse scale 31. The verticality detection component 32 is movably installed on the support block 33 through the lap rod 34. The transverse scale 31 is slidably connected to the support column 2 through the slider 5. The support block 33 is provided with an adjustment slot that is compatible with the verticality detection component 32. There are two adjustment slots, and they are chamfered. The transverse scale 31 and the support column 2 are arranged vertically. The verticality detection component 32 can swing on the lap rod 34 and move with the support block 33 until it fits with the core sample, thereby measuring the verticality of the core sample.

[0030] The slider 5 and the transverse scale 31 are integrated into one piece. The slider 5 is adapted to the support column 2 and is arranged on the support column 2 in a square shape. A locking bolt 7 is installed on the slider 5. The slider 5 is in a free sliding state, and the transverse scale 31 slides with it. When the core sample is placed, the slider 5 is naturally placed on the top surface of the core sample for detection. When the core sample is replaced, the slider 5 is firmly locked by the two locking bolts 7, and is unlocked again after the core sample is replaced. In order to avoid the verticality detection component 32 sliding down with the transverse scale 31 without core sample support, it may collide with the supporting base plate 1 and be damaged.

[0031] The verticality detection assembly 32 includes a protractor 321, an upper pointer 322 and a lower swing member 323. The protractor 321 is located in the center of the top surface of the support block 33. The lower swing member 323 is movably installed on the bridge rod 34. An upper pointer 322 is installed on the top of the lower swing member 323. The upper pointer 322 passes through an adjustment slot and is attached to the protractor 321. The two adjustment slots are located on both sides of the protractor 321. The number of upper pointers 322 is preferably two, which pass through opposite adjustment slots respectively. In the normal state, the lower swing member 323 is parallel to the support column 2 due to gravity factors, and the upper pointer 322 points to 90 degrees. The two ends of the adjustment slot are chamfered to facilitate the upper pointer 322 to swing and point in a wider range.

[0032] A through slot is provided in the middle of the transverse scale 31, and the lower swing piece 323 is located in the through slot. The through slot of the transverse scale 31 is a vertical through slot, and a through slot is also provided in the transverse direction to form a cross through slot. The lap rod 34 passes through the transverse through slot and is connected to the support block 33, thereby driving the verticality detection component 32 to slide on the transverse scale 31. The lower swing piece 323 is passed through by the lap rod 34 and hung on the transverse scale 31. The through slot is adapted to the lower swing piece 323 to ensure that it is in the center position, providing accurate verticality detection.

[0033] Working principle: The staff assembles the measuring device, screws the support column 2 into the support base plate 1, and further sets the adjustable horizontal measuring ruler 3 on the support column 2 through the slider 5, and secures it to the end of the support column 2 by tightening the bolts, and further tightens the capping block 6 to complete the assembly;

[0034] Twist the adjusting foot 8 to make the entire device horizontal. At this time, the verticality detection component 32 is parallel to the support column 2 and points to 90 degrees. At this time, the staff places the core sample on the support chassis and makes it close to the support column 2. At this time, release the tightening bolts, so that the horizontal measuring ruler automatically slides down until it abuts against the core sample, and reads its height according to the scale on the support column 2. At this time, the sliding support block 33 reads the diameter while making the lower swing piece 323 of the verticality detection component 32 stick to the core sample wall until it is parallel to the vertical axis of the core sample. The lower swing piece 323 drives the upper pointer 322 to adjust. At this time, read the angle between the protractor 321 and the upper pointer 322 for verticality detection.
