Description

Technical Field

[0001] The invention relates to the technical field of road test and detection, in particular to a water-stable core sample end surface leveler. Background Art

[0002] At present, with the improvement of highway grades, water-stable base layers are widely used. The design of water-stable base layers mainly relies on indoor mold forming. The samples are standardized and the data produced is stable.

[0003] Because water-stabilized core samples are weak and somewhat loose, they can break and fall during cutting. This results in unevenness on both ends of the core samples under uniaxial compression, leading to a dispersion of strength values ​​within a batch, with the coefficient of variation easily exceeding 15%. Therefore, neither cutting nor grinding can meet the requirements. According to T0805-1994, "Test Procedure for Unconfined Compressive Strength of Inorganic Binder Stabilized Materials for Highway Engineering," in the "Test Procedure for Inorganic Binder Stabilized Materials for Highway Engineering," 3.4, use a scraper to smooth both top surfaces of the specimen. If necessary, use fast-setting cement mortar to smooth the top surface.

[0004] Since most current water-stable aggregate bases are made of water-stable crushed stone, scrapers cannot be used to level them. Smoothing the top surface with quick-setting cement mortar can result in significant operator error, resulting in uneven, substandard bearing surfaces. In this situation, a device was necessary to quickly smooth both top surfaces of the water-stable specimen to meet technical requirements, thus addressing the equipment gap in this testing method.

[0005] Therefore, we proposed a water-stable core-like end face flattener. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] The embodiment of the present application solves the problem that the water-stabilizing core sample is not strong enough and is not dense enough, which causes damage and falling of the material during the cutting process; and the problem that the two end surfaces of the core sample are uneven in uniaxial compression resistance. The water-stabilizing material can form two water-stabilizing core samples with flat end surfaces in the circular sleeve formed by the pad block 101, the leveling block 201 and the two arc-shaped clamping plates 3.

[0033] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] Example 1

[0035] The embodiment of the present invention discloses a water-stable core sample end surface smoother.

[0036] According to the attached Figure 1-5As shown, it includes a base 1 and a movable base 2. A pad 101 is fixedly installed at the geometric center of the upper surface of the base 1. A first transmission assembly is provided inside the base 1. Two movable sleeves 102 are provided on the upper surface of the base 1. Moving rods 103 are movably inserted into the interior of the two movable sleeves 102. The top ends of the two movable rods 103 extend outward.

[0037] A leveling block 201 is installed at the bottom of the moving base 2, and the leveling block 201 is located directly above the pad 101. A second transmission assembly is assembled between the moving base 2 and the top ends of the two moving rods 103.

[0038] An arc-shaped clamping plate 3 is installed on the opposite side of the two movable sleeves 102. The two arc-shaped clamping plates 3 are pressed against each other to form a circular sleeve shape, and the pad 101 and the leveling block 201 are respectively fitted with the bottom inner wall and the top inner wall of the circular sleeve formed by the two arc-shaped clamping plates 3, and two overflow holes 301 that pass through the inside and outside are provided at the connection between the two arc-shaped clamping plates 3.

[0039] A certain amount of water-stabilizing material can be poured into the mold formed by the two arc-shaped splints 3 and the pad 101, and then the movable seat 2 is pushed downward so that the leveling block 201 squeezes the water-stabilizing material until the leveling block 201 fits against the top inner wall of the circular sleeve formed by the two arc-shaped splints 3, and in the process of the leveling block 201 squeezing the water-stabilizing material, the excess mortar between the two arc-shaped splints 3 can flow out from the multiple overflow holes 301, so that the water-stabilizing material can form two water-stabilizing core samples with flat end faces in the circular sleeve formed by the pad 101 and the leveling block 201 and the two arc-shaped splints 3; after the water-stabilizing core sample is formed, the bolts on the adjacent fastening blocks 302 on the outer surfaces of the two arc-shaped splints 3 are opened to separate the two arc-shaped splints 3, so that the water-stabilizing core sample between the two arc-shaped splints 3 can be taken out, and then the water-stabilizing core sample can be subjected to a strength test.

[0040] Four connecting rods 202 are fixedly connected to the lower surface of the movable base 2, and the bottom ends of the four connecting rods 202 are fixedly connected to the upper surface of the leveling block 201;

[0041] A handle 203 is fixedly connected to the upper surface of the movable base 2. The movable base 2 can be easily pulled by the handle 203 so that the movable base 2 can drive the leveling block 201 to move vertically.

[0042] Two arcuate bars 104 are fixedly connected to the outer surface of the movable sleeve 102, and two sets of mounting blocks 105 are symmetrically fixedly connected to the outer surface of the arcuate clamping plate 3. The ends of the arcuate bars 104 are inserted between the two mounting blocks 105 and fixedly connected by bolts.

[0043] By setting the arc strip 104 and multiple mounting blocks 105, the end of the arc strip 104 is inserted between the two mounting blocks 105 and fixedly connected by bolts. Therefore, when the arc splint 3 is damaged, the bolts can be opened, thereby facilitating the replacement of the arc splint 3.

[0044] A plurality of fastening blocks 302 are fixedly connected to the outer surface of the arc-shaped clamping plate 3 , and two adjacent fastening blocks 302 are fixedly connected by bolts.

[0045] Working principle: During use, the movable base 2 is pulled upward, thereby driving the leveling block 201 to move upward, and causing the two movable rods 103 to move upward in the two movable sleeves 102 respectively until they move to a suitable height;

[0046] At this time, the two arc-shaped splints 3 are pressed against each other to form a circular sleeve shape, and the pad 101 is in contact with the bottom inner wall of the circular sleeve formed by the two arc-shaped splints 3. At this time, the adjacent fastening blocks 302 on the outer surfaces of the two arc-shaped splints 3 are fastened by bolts;

[0047] Then, a certain amount of water-stabilizing material can be poured into the mold formed by the two arc-shaped splints 3 and the pad 101, and then the movable seat 2 is pushed downward so that the leveling block 201 squeezes the water-stabilizing material until the leveling block 201 fits against the top inner wall of the circular sleeve formed by the two arc-shaped splints 3. In the process of the leveling block 201 squeezing the water-stabilizing material, the excess mortar between the two arc-shaped splints 3 can flow out from the multiple overflow holes 301, so that the water-stabilizing material can form two water-stabilizing core samples with flat end surfaces in the circular sleeve formed by the pad 101, the leveling block 201 and the two arc-shaped splints 3;

[0048] After the water-stabilizing core sample is formed, the bolts on the adjacent fastening blocks 302 on the outer surfaces of the two arc-shaped splints 3 are opened to separate the two arc-shaped splints 3, so that the water-stabilizing core sample between the two arc-shaped splints 3 can be taken out, and then the water-stabilizing core sample can be subjected to a strength test.

[0049] Example 2

[0050] The embodiment of the present invention discloses a water-stable core sample end surface smoother.

[0051] According to the attached Figure 1-4 As shown, it includes a base 1 and a movable base 2. A pad 101 is fixedly installed at the geometric center of the upper surface of the base 1. A first transmission assembly is provided inside the base 1. Two movable sleeves 102 are provided on the upper surface of the base 1. Moving rods 103 are movably inserted into the interior of the two movable sleeves 102. The top ends of the two movable rods 103 extend outward.

[0052] A leveling block 201 is installed at the bottom of the moving base 2, and the leveling block 201 is located directly above the pad 101. A second transmission assembly is assembled between the moving base 2 and the top ends of the two moving rods 103.

[0053] An arc-shaped clamping plate 3 is installed on the opposite side of the two movable sleeves 102. The two arc-shaped clamping plates 3 are pressed against each other to form a circular sleeve shape, and the pad 101 and the leveling block 201 are respectively fitted with the bottom inner wall and the top inner wall of the circular sleeve formed by the two arc-shaped clamping plates 3, and two overflow holes 301 that pass through the inside and outside are provided at the connection between the two arc-shaped clamping plates 3.

[0054] By setting the first transmission assembly and the second transmission assembly, when one of the movable sleeves 102 and the movable rod 103 is pulled to move, the other movable sleeve 102 and the movable rod 103 are moved at the same time through the two first movable bars 4 and the second movable bars 5. On the one hand, it is convenient for the separation and merging of the two arc-shaped splints 3, and can be quickly positioned to fit with the pad 101. On the other hand, the two first movable bars 4 prevent the movable seat 2 and the two second movable bars 5 from moving in one direction as a whole, and the movable seat 2 cannot move with any of the second movable bars 5. The horizontal position of the movable seat 2 and the leveling block 201 is always positioned. Regardless of the separation or merging of the two arc-shaped splints 3, the leveling block 201 is always directly above the two arc-shaped splints 3, which facilitates the leveling block 201 to squeeze the water-stabilizing material, thereby making the leveling block 201 fit with the top inner wall of the circular sleeve formed by the two arc-shaped splints 3.

[0055] The first transmission assembly includes two first movable bars 4, a cavity 401 is provided inside the base 1, and the two first movable bars 4 are slidably connected to the inner wall of the cavity 401. Two sliding grooves 402 are symmetrically provided on the upper surface of the base 1, and the two sliding grooves 402 are connected to the cavity 401. The upper surfaces of the ends of the two first movable bars 4 are fixedly connected with sliders 403, and the two sliders 403 are respectively slidably connected to the inner walls of the two sliding grooves 402, and the bottom ends of the two movable sleeves 102 are respectively fixedly connected to the upper surfaces of the two sliders 403.

[0056] A first rotating shaft 404 is rotatably connected to the inner wall of the cavity 401, and a first transmission gear 405 is fixedly sleeved on the outer surface of the first rotating shaft 404. Two first transmission racks 406 are respectively meshed and connected on both sides of the first transmission gear 405, and the two first transmission racks 406 are respectively fixedly connected to the sides of the two first movable bars 4.

[0057] The second transmission assembly includes two second movable bars 5. The movable seat 2 is provided with a through slot extending left and right. The two second movable bars 5 are slidably connected to the inner wall of the through slot, and the ends of the two second movable bars 5 are fixedly connected to the top ends of the two movable rods 103 respectively.

[0058] A second rotating shaft 501 is rotatably connected to the inner wall of the through groove, and a second transmission gear 502 is fixedly sleeved on the outer surface of the second rotating shaft 501. Two second transmission racks 503 are respectively engaged and connected on both sides of the second transmission gear 502, and the two second transmission racks 503 are respectively fixedly connected to the sides of the two second movable bars 5.

[0059] Working Principle: During use, the two sides of the first transmission gear 405 on the outer surface of the first rotating shaft 404 are respectively engaged with the two first transmission racks 406, and the two first transmission racks 406 are respectively fixedly connected to the sides of the two first movable bars 4, so that the two first movable bars 4 can only move towards each other or away from each other, and the movement distance is the same;

[0060] At the same time, two second transmission racks 503 are respectively meshed and connected to the two sides of the second transmission gear 502 on the outer surface of the second rotating shaft 501, and the two second transmission racks 503 are respectively fixedly connected to the sides of the two second movable bars 5, so that the two second movable bars 5 can only move towards each other or away from each other, and the movement distance is the same;

[0061] Therefore, when one of the movable sleeves 102 and the movable rod 103 is pulled to move, the other movable sleeve 102 and the movable rod 103 are moved at the same time through the two first movable bars 4 and the second movable bar 5. On the one hand, it is convenient for the separation and merging of the two arc-shaped splints 3, and can be quickly positioned to fit with the pad 101. On the other hand, the two first movable bars 4 prevent the movable seat 2 and the two second movable bars 5 from moving in one direction as a whole, and the movable seat 2 cannot move with any of the second movable bars 5. The horizontal position of the movable seat 2 and the leveling block 201 is always positioned. Regardless of the separation or merging of the two arc-shaped splints 3, the leveling block 201 is always directly above the two arc-shaped splints 3, which facilitates the leveling block 201 to squeeze the water-stabilizing material, thereby making the leveling block 201 fit with the top inner wall of the circular sleeve formed by the two arc-shaped splints 3.

[0062] In summary:

[0063] During use, the movable base 2 is pulled upward, thereby driving the leveling block 201 to move upward, and causing the two movable rods 103 to move upward in the two movable sleeves 102 respectively until they move to a suitable height;

[0064] At this time, the two arc-shaped splints 3 are pressed against each other to form a circular sleeve shape, and the pad 101 is in contact with the bottom inner wall of the circular sleeve formed by the two arc-shaped splints 3. At this time, the adjacent fastening blocks 302 on the outer surfaces of the two arc-shaped splints 3 are fastened by bolts;

[0065] Then, a certain amount of water-stabilizing material can be poured into the mold formed by the two arc-shaped splints 3 and the pad 101, and then the movable seat 2 is pushed downward so that the leveling block 201 squeezes the water-stabilizing material until the leveling block 201 fits against the top inner wall of the circular sleeve formed by the two arc-shaped splints 3. In the process of the leveling block 201 squeezing the water-stabilizing material, the excess mortar between the two arc-shaped splints 3 can flow out from the multiple overflow holes 301, so that the water-stabilizing material can form two water-stabilizing core samples with flat end surfaces in the circular sleeve formed by the pad 101, the leveling block 201 and the two arc-shaped splints 3;

[0066] After the water-stabilizing core sample is formed, the bolts on the adjacent fastening blocks 302 on the outer surfaces of the two arc-shaped splints 3 are opened to separate the two arc-shaped splints 3, so that the water-stabilizing core sample between the two arc-shaped splints 3 can be taken out, and then the water-stabilizing core sample can be subjected to a strength test.

[0067] Because both sides of the first transmission gear 405 on the outer surface of the first rotating shaft 404 are respectively engaged with the two first transmission racks 406, and the two first transmission racks 406 are respectively fixedly connected to the sides of the two first movable bars 4, the two first movable bars 4 can only move towards each other or away from each other, and the movement distance is the same;

[0068] At the same time, two second transmission racks 503 are respectively meshed and connected to the two sides of the second transmission gear 502 on the outer surface of the second rotating shaft 501, and the two second transmission racks 503 are respectively fixedly connected to the sides of the two second movable bars 5, so that the two second movable bars 5 can only move towards each other or away from each other, and the movement distance is the same;

[0069] Therefore, when one of the movable sleeves 102 and the movable rod 103 is pulled to move, the other movable sleeve 102 and the movable rod 103 are moved at the same time through the two first movable bars 4 and the second movable bar 5. On the one hand, it is convenient for the separation and merging of the two arc-shaped splints 3, and can be quickly positioned to fit with the pad 101. On the other hand, the two first movable bars 4 prevent the movable seat 2 and the two second movable bars 5 from moving in one direction as a whole, and the movable seat 2 cannot move with any of the second movable bars 5. The horizontal position of the movable seat 2 and the leveling block 201 is always positioned. Regardless of the separation or merging of the two arc-shaped splints 3, the leveling block 201 is always directly above the two arc-shaped splints 3, which facilitates the leveling block 201 to squeeze the water-stabilizing material, thereby making the leveling block 201 fit with the top inner wall of the circular sleeve formed by the two arc-shaped splints 3.
