Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically to a concrete strength testing device for road construction. Background Technology

[0002] Chinese utility model patent CN214794207U discloses a concrete strength testing device, including a trolley, a stamping assembly, a clamping assembly, a testing platform, and a driving assembly. The stamping assembly is mounted on the trolley via a U-shaped frame, the testing platform is mounted on the trolley below the stamping assembly, and the clamping assembly is mounted on the testing platform and connected to the driving assembly.

[0003] The concrete strength testing equipment disclosed in this patent document can test the strength of the laid concrete road during the road construction process.

[0004] The specific testing method is as follows: using the same concrete road construction process, the concrete is poured into the construction frame. After the concrete test block has cured and formed, the construction frame is removed. Then, the concrete test block is transported to the strength testing device. The tester manually places the concrete test block on the strength testing device and manually aligns it. Pressure is applied to the concrete test block until it breaks. After breaking, the broken concrete test block is moved to the waste area.

[0005] However, while the clamping assembly in this patent document can accommodate concrete test blocks of different sizes, the pressing assembly in the testing device continuously applies pressure to the concrete test block, and the downward force of this pressure is continuously applied to the wheels of the trolley, as described in the patent document. Figure 1 As shown, the wheels of the car have limited load-bearing capacity and cannot withstand large loads of impact.

[0006] Based on this, a concrete strength testing device for road construction is proposed. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this utility model provides a concrete strength testing device for road construction, which solves the problem mentioned in the background art: Although the clamping component in the concrete strength testing device disclosed in Chinese Utility Model No. CN214794207U can adapt to concrete test blocks of different sizes, the pressing component in this testing device continuously applies pressure to the concrete test block, and the downward force of the pressing component continuously acts on the wheels of the trolley. However, the load-bearing capacity of the trolley wheels is limited and it is difficult to withstand the large load of the pressing force.

One top end of each slider extends outward from its corresponding guide groove. C-shaped clamping arms are fixedly installed on the inner side walls of both sliders.

[0014] A stamping mechanism, which is mounted on a flatbed cart;

[0015] The stamping mechanism includes an inverted U-shaped fixing frame, which is fixedly installed at the top center of the flatbed cart. A hydraulic cylinder is fixedly installed on the top of the inverted U-shaped fixing frame. The hydraulic rod of the hydraulic cylinder passes through the top of the inverted U-shaped fixing frame downward and extends into the inner cavity of the inverted U-shaped fixing frame. A stamping base is fixedly installed at the end of the hydraulic rod of the hydraulic cylinder.

[0016] Two sets of hydraulic vehicle body support mechanisms are installed on both sides of the flatbed truck. The two sets of hydraulic vehicle body support mechanisms can lift the flatbed truck upward and lift the four omnidirectional casters off the ground.

[0017] Preferably, internal threaded sleeves are fixedly installed on the outer walls of both ends of the two C-shaped clamping arms, and the inner cavities of the two sets of internal threaded sleeves are connected to the inner cavities of the corresponding C-shaped clamping arms.

[0018] Each of the internal threaded sleeves is threadedly fitted with a threaded clamping rod, and a handwheel is fixedly installed at one outer end of each threaded clamping rod, while an abutment is fixedly installed at one inner end of each threaded clamping rod.

[0019] Preferably, each handwheel has multiple levers distributed circumferentially, and all four sets of levers are integrally formed with the corresponding handwheel.

[0020] Preferably, the motor is a geared motor.

[0021] Preferably, the stamping base is rectangular.

[0022] Preferably, both sets of hydraulic vehicle body support mechanisms include hydraulic lifting cylinders. The two hydraulic lifting cylinders are respectively located on opposite side walls of the flatbed vehicle, and the hydraulic rods of the two hydraulic lifting cylinders are both downward-facing. Support plates are fixedly installed at the ends of the hydraulic rods of the two hydraulic lifting cylinders.

[0023] Preferably, each of the two hydraulic lifting cylinders is fixedly mounted with a cylinder body fixing seat, and both cylinder body fixing seats are fixedly connected to the side wall of the flatbed cart.

[0024] Preferably, guide rods are fixedly installed at both ends of the upper surface of the two support plates, and guide bases are provided on both sets of guide rods. Both sets of guide bases are fixedly connected to the side wall of the flatbed truck.

[0025] Each of the guide rods can slide on its corresponding guide base.

[0026] (III) Beneficial Effects

[0027] This utility model provides a concrete strength testing device for road construction, which has the following beneficial effects:

[0028] I. In this utility model, two sets of hydraulic vehicle body support mechanisms are respectively installed on both sides of the flatbed cart. The two sets of hydraulic vehicle body support mechanisms can lift the flatbed cart upwards and lift the four omnidirectional casters off the ground. When the two sets of hydraulic vehicle body support mechanisms lift the flatbed cart upwards and the four omnidirectional casters are off the ground and not in contact with the ground, the downward pressure of the stamping mechanism during the stamping test can be avoided from acting directly on the four omnidirectional casters. At the same time, when the two sets of hydraulic vehicle body support mechanisms lift the flatbed cart and support the testing equipment, the downward pressure of the stamping mechanism during the stamping test can be borne by the two sets of hydraulic vehicle body support mechanisms, thereby improving the stability of the testing equipment and enabling the testing equipment to withstand a large load of stamping pressure.

[0029] Second, in this utility model, when the hydraulic rod of each hydraulic lifting cylinder extends downward, it can cause the corresponding support plate to move downward. When the two support plates contact the ground at the same time, the two hydraulic lifting cylinders continue to work. At this time, due to the reaction force from the ground, the trolley will be lifted upward, and the four omnidirectional casters will leave the ground and separate from the ground. At this time, the overall force of the testing equipment is transferred from the four omnidirectional casters to the two sets of hydraulic vehicle body support mechanisms, thereby improving the stability of the testing equipment during the stamping test.

[0030] III. In this utility model, guide rods are fixedly installed at both ends of the upper surface of the two support plates, and guide bases are provided on both sets of guide rods. Both sets of guide bases are fixedly connected to the side wall of the flatbed cart.

[0031] Each guide rod can slide on its corresponding guide base, which makes the force on both ends of the two support plates more balanced and also makes the two support plates more stable.

[0032] IV. In this utility model, when the motor drives the left and right screws through its output shaft, the forward or reverse rotation of the left and right screws can make the two screw nuts move closer or further apart. At the same time, when the two screw nuts are moving, they can drive the movement of the corresponding sliders. The C-shaped clamps installed on the sliders can move synchronously with the movement of the sliders.

[0033] Therefore, the two symmetrically arranged C-shaped clamping arms can move closer or further away with the two lead screw nuts;

[0034] The two C-shaped clamping arms can clamp the concrete test block to be tested. When the two C-shaped clamping arms are close to each other, they can clamp and fix the concrete test block. Therefore, under the action of the clamping mechanism, concrete test blocks of different sizes can be clamped.

[0035] V. In this utility model, when the concrete test block is clamped and fixed between two C-shaped clamping arms, the two C-shaped clamping arms can clamp and fix the concrete test block from both sides. At the same time, rotating the corresponding handwheel will drive the corresponding threaded clamping rod. Each threaded clamping rod can move in the corresponding internal thread sleeve. Each threaded clamping rod will clamp and fix the edge of the concrete test block through the corresponding abutment, thereby enabling the clamping mechanism to clamp and fix concrete test blocks of different sizes.

[0036] VI. In this utility model, when the hydraulic cylinder is started, it can move the stamping base downward through its hydraulic rod until it presses against the clamped concrete test block. When the stamping base continues to press down, the tester observes the compressive bearing limit of the concrete test block.

[0037] Therefore, the strength bearing capacity of concrete specimens can be tested through a stamping mechanism.

[0038] VII. In this utility model, through the cooperation between the clamping mechanism and the stamping mechanism, not only can the strength of concrete test blocks be tested, but also concrete test blocks of different sizes can be clamped and fixed.

[0039] 8. In this utility model, each set of handles allows the testing personnel to easily rotate the corresponding handwheel. Attached Figure Description

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Example 1

[0049] like Figure 1-6 As shown, this utility model provides a technical solution:

[0050] A concrete strength testing device for road construction includes a flatbed cart 1, with omnidirectional casters 2 fixedly installed at each of the four corners of the bottom of the cart 1, and a pusher frame 3 fixedly installed on one side of the top of the cart 1. It also includes:

[0051] Clamping mechanism 4 is installed on the flatbed cart 1;

[0052] The clamping mechanism 4 includes an inverted U-shaped base 41, which is fixedly installed on the top of the trolley 1. Guide grooves 42 are symmetrically opened on both sides of the top of the inverted U-shaped base 41. A motor 43 is fixedly installed in the middle of one side wall of the inverted U-shaped base 41. The output shaft of the motor 43 extends into the inner cavity of the inverted U-shaped base 41. A left-hand and right-hand screw 44 is rotatably installed in the middle of the inner cavity of the inverted U-shaped base 41. The left-hand and right-hand screw 44 has two symmetrically arranged threaded parts, and the two symmetrically arranged threaded parts of the left-hand and right-hand screw 44 correspond to the two guide grooves 42 respectively. A screw nut 45 is threadedly installed on each of the two symmetrically arranged threaded parts of the left-hand and right-hand screw 44. A slider 46 is fixedly installed on each of the two screw nuts 45. The top end of each slider 46 extends outward from the corresponding guide groove 42. A C-shaped clamping arm 47 is fixedly installed on the inner side wall of each slider 46.

[0053] When the motor 43 drives the left and right screws 44 through its output shaft, the forward or reverse rotation of the left and right screws 44 can make the two screw nuts 45 move closer or further apart. At the same time, when the two screw nuts 45 are moving, they can drive the movement of the corresponding sliders 46. The C-shaped clamps 47 installed on the sliders 46 can move synchronously with the movement of the sliders 46.

[0054] Therefore, the two symmetrically arranged C-shaped clamping arms 47 can move closer or further away with the two lead screw nuts 45;

[0055] The concrete test block 7 to be tested can be clamped between the two C-shaped clamping arms 47. When the two C-shaped clamping arms 47 are close to each other, the concrete test block 7 can be clamped and fixed. Therefore, under the action of the clamping mechanism 4, concrete test blocks 7 of different sizes can be clamped.

[0056] The stamping mechanism 5 is mounted on the flatbed carriage 1;

[0057] The stamping mechanism 5 includes an inverted U-shaped fixing frame 51, which is fixedly installed at the top center of the flatbed trolley 1. A hydraulic cylinder 52 is fixedly installed on the top of the inverted U-shaped fixing frame 51. The hydraulic rod of the hydraulic cylinder 52 passes through the top of the inverted U-shaped fixing frame 51 and extends into the inner cavity of the inverted U-shaped fixing frame 51. A stamping base 53 is fixedly installed at the end of the hydraulic rod of the hydraulic cylinder 52.

[0058] The inverted U-shaped fixing frame 51 is used to support and fix the hydraulic cylinder 52. When the hydraulic cylinder 52 is started, it can move the stamping base 53 downward through its hydraulic rod until it is pressed onto the clamped concrete test block 7. When the stamping base 53 continues to press down, the tester observes the compressive bearing limit of the concrete test block 7.

[0059] Therefore, through the cooperation between the clamping mechanism 4 and the punching mechanism 5, not only can the strength of the concrete test block 7 be tested, but also concrete test blocks 7 of different sizes can be clamped and fixed.

[0060] Two sets of hydraulic vehicle body support mechanisms 6 are installed on both sides of the flatbed trolley 1. The two sets of hydraulic vehicle body support mechanisms 6 can lift the flatbed trolley 1 upwards and lift the four omnidirectional casters 2 off the ground. When the two sets of hydraulic vehicle body support mechanisms 6 lift the flatbed trolley 1 upwards and the four omnidirectional casters 2 are off the ground and not in contact with the ground, the downward pressure of the stamping test of the stamping mechanism 5 can be avoided from acting directly on the four omnidirectional casters 2. At the same time, when the two sets of hydraulic vehicle body support mechanisms 6 lift the flatbed trolley 1 and support the testing equipment, the downward pressure of the stamping test of the stamping mechanism 5 can be borne by the two sets of hydraulic vehicle body support mechanisms 6, thereby improving the stability of the testing equipment.

[0061] Example 2

[0062] like Figure 1-6 As shown, improvements are made based on Example 1:

[0063] In order to better clamp and fix concrete test blocks 7 of different sizes, in this embodiment, internal thread sleeves 48 are fixedly installed on the outer walls of both ends of the two C-shaped clamping arms 47, and the inner cavities of the two sets of internal thread sleeves 48 are connected to the inner cavities of the corresponding C-shaped clamping arms 47.

[0064] Each internal threaded sleeve 48 is threadedly fitted with a threaded clamping rod 49. A handwheel 410 is fixedly mounted on one outer end of each threaded clamping rod 49, and an abutment 412 is fixedly mounted on one inner end of each threaded clamping rod 49. Figure 2 and Figure 5 As shown, when the concrete specimen 7 is clamped and fixed between the two C-shaped clamping arms 47, the two C-shaped clamping arms 47 can clamp and fix the concrete specimen 7 from both sides. At the same time, the corresponding handwheels 410 are rotated respectively. Each handwheel 410 will drive the corresponding threaded clamping rod 49. Each threaded clamping rod 49 can move in the corresponding internal thread sleeve 48. Each threaded clamping rod 49 will clamp and fix the edge of the concrete specimen 7 through the corresponding abutment 412, thereby enabling the clamping mechanism 4 to clamp and fix concrete specimens 7 of different sizes.

[0065] In order to make it easier for the inspector to rotate the handwheel 410, in this embodiment, each handwheel 410 is further provided with multiple handles 411 distributed circumferentially. The four sets of handles 411 are integrally formed with the corresponding handwheel 410, and each set of handles 411 can facilitate the inspector to rotate the corresponding handwheel 410.

[0066] In order to enable the motor 43 to rotate in both forward and reverse directions, and also to increase the torque of the motor 43, in this embodiment, the motor 43 is further configured as a servo geared motor.

[0067] In order to enable the stamping base 53 to have a variety of different geometries, in this embodiment, the stamping base 53 is rectangular, or it can be disc-shaped or other geometries (not shown in the figure).

[0068] Example 3

[0069] like Figure 1-6 As shown, improvements are made based on Example 1:

[0070] In order to optimize the specific structure of the hydraulic body support mechanism 6, in this embodiment, both sets of hydraulic body support mechanisms 6 further include hydraulic lifting cylinders 61. The two hydraulic lifting cylinders 61 are respectively set on the opposite side walls of the flatbed 1, and the hydraulic rods of the two hydraulic lifting cylinders 61 are both set downward. Support plates 62 are fixedly installed at the ends of the hydraulic rods of the two hydraulic lifting cylinders 61. When the hydraulic rod of each hydraulic lifting cylinder 61 extends downward, it can make the corresponding support plate 62 move downward. When the two support plates 62 contact the ground at the same time, the two hydraulic lifting cylinders 61 continue to work. At this time, due to the reaction force from the ground, the flatbed 1 will be lifted upward, and the four omnidirectional casters 2 will leave the ground and separate from the ground. At this time, the overall force of the testing equipment is transferred from the four omnidirectional casters 2 to the two sets of hydraulic body support mechanisms 6, thereby improving the stability of the testing equipment during the stamping test.

[0071] Both support plates 62 are made of high-strength steel plates.

[0072] In order to fix the two hydraulic lifting cylinders 61, in this embodiment, cylinder body fixing seats 65 are fixedly installed on the cylinder barrels of the two hydraulic lifting cylinders 61, and the two cylinder body fixing seats 65 are fixedly connected to the side wall of the flatbed trolley 1.

[0073] In order to make the force on both ends of the two support plates 62 more balanced and to make the stability of the two support plates 62 better, in this embodiment, guide rods 63 are fixedly installed on both ends of the upper surface of the two support plates 62, and guide bases 64 are provided on both sets of guide rods 63. Both sets of guide bases 64 are fixedly connected to the side wall of the board car 1.

[0074] Each guide rod 63 can slide on its corresponding guide base 64.

[0075] In summary, the workflow of this utility model is as follows:

[0076] like Figure 1-6 As shown, when the motor 43 drives the left and right screws 44 through its output shaft, the forward or reverse rotation of the left and right screws 44 can make the two screw nuts 45 move closer or further apart. At the same time, when the two screw nuts 45 are moving, they can drive the movement of the corresponding sliders 46. The C-shaped clamps 47 installed on the sliders 46 can move synchronously with the movement of the sliders 46.

[0077] Therefore, the two symmetrically arranged C-shaped clamping arms 47 can move closer or further away with the two lead screw nuts 45;

[0078] The concrete test block 7 to be tested can be clamped between the two C-shaped clamping arms 47. When the two C-shaped clamping arms 47 are close to each other, the concrete test block 7 can be clamped and fixed. Therefore, under the action of the clamping mechanism 4, concrete test blocks 7 of different sizes can be clamped.

[0079] More specifically:

[0080] To better clamp and fix concrete test blocks 7 of different sizes, each internal threaded sleeve 48 is threadedly fitted with a threaded clamping rod 49. A handwheel 410 is fixedly installed at one outer end of each threaded clamping rod 49, and an abutment 412 is fixedly installed at one inner end of each threaded clamping rod 49. Figure 2 and Figure 5 As shown, when the concrete specimen 7 is clamped and fixed between the two C-shaped clamping arms 47, the two C-shaped clamping arms 47 can clamp and fix the concrete specimen 7 from both sides. At the same time, the corresponding handwheels 410 are rotated respectively. Each handwheel 410 will drive the corresponding threaded clamping rod 49. Each threaded clamping rod 49 can move in the corresponding internal thread sleeve 48. Each threaded clamping rod 49 will clamp and fix the edge of the concrete specimen 7 through the corresponding abutment 412, thereby enabling the clamping mechanism 4 to clamp and fix concrete specimens 7 of different sizes.

[0081] The inverted U-shaped fixing frame 51 is used to support and fix the hydraulic cylinder 52. When the hydraulic cylinder 52 is started, it can move the stamping base 53 downward through its hydraulic rod until it is pressed onto the clamped concrete test block 7. When the stamping base 53 continues to press down, the tester observes the compressive bearing limit of the concrete test block 7.

[0082] Therefore, through the cooperation between the clamping mechanism 4 and the punching mechanism 5, not only can the strength of the concrete test block 7 be tested, but also concrete test blocks 7 of different sizes can be clamped and fixed.

[0083] Two sets of hydraulic vehicle body support mechanisms 6 are respectively installed on both sides of the flatbed trolley 1. The two sets of hydraulic vehicle body support mechanisms 6 can lift the flatbed trolley 1 upward and lift the four omnidirectional casters 2 off the ground. When the two sets of hydraulic vehicle body support mechanisms 6 lift the flatbed trolley 1 upward and the four omnidirectional casters 2 are off the ground and do not contact the ground, the downward pressure of the stamping test of the stamping mechanism 5 can be avoided from acting directly on the four omnidirectional casters 2. At the same time, when the two sets of hydraulic vehicle body support mechanisms 6 lift the flatbed trolley 1 and support the testing equipment, the downward pressure of the stamping test of the stamping mechanism 5 can be borne by the two sets of hydraulic vehicle body support mechanisms 6, thereby improving the stability of the testing equipment.

[0084] Specifically:

[0085] Both sets of hydraulic vehicle body support mechanisms 6 include hydraulic lifting cylinders 61. The two hydraulic lifting cylinders 61 are respectively set on the opposite side walls of the flatbed trolley 1, and the hydraulic rods of the two hydraulic lifting cylinders 61 are both set downward. The ends of the hydraulic rods of the two hydraulic lifting cylinders 61 are fixedly installed with support plates 62. When the hydraulic rod of each hydraulic lifting cylinder 61 extends downward, it can make the corresponding support plate 62 move downward. When the two support plates 62 contact the ground at the same time, the two hydraulic lifting cylinders 61 continue to work. At this time, due to the reaction force from the ground, the flatbed trolley 1 will be lifted upward, and the four omnidirectional casters 2 will leave the ground and separate from the ground. At this time, the overall force of the testing equipment is transferred from the four omnidirectional casters 2 to the two sets of hydraulic vehicle body support mechanisms 6, thereby improving the stability of the testing equipment during the stamping test.

[0086] Furthermore, both support plates 62 are made of high-strength steel plates;

[0087] More specifically:

[0088] In order to make the force on both ends of the two support plates 62 more balanced and to make the stability of the two support plates 62 better, guide rods 63 are fixedly installed on both ends of the upper surface of the two support plates 62. Guide bases 64 are provided on both sets of guide rods 63, and both sets of guide bases 64 are fixedly connected to the side wall of the flatbed trolley 1.

[0089] Each guide rod 63 can slide on its corresponding guide base 64.
