Description

Concrete sampler Technical Field

[0001] This utility model relates to the field of concrete sampling technology, specifically a concrete sampler. Background Technology

[0002] Concrete is a common building material, mainly composed of cement, sand, gravel, and water mixed in a certain proportion. Its characteristic is that it gradually hardens after being mixed with water, forming a strong and durable structure, and is widely used in the construction of houses, bridges, roads, and other projects. Concrete has advantages such as low cost, high compressive strength, and high plasticity, making it an indispensable basic engineering material in modern society.

[0003] According to the search results, Chinese patent document, publication number CN 222635837 U, relates to the field of concrete testing technology, specifically a concrete sampler that is more convenient to use and improves practicality. It includes a sampling box with a storage slot inside. An edge is fixedly provided on the top of the outer wall of the sampling box, and a base plate is fixedly provided on the bottom. A frame is slidably installed in the middle of the outer side of the sampling box. Several springs are provided between the frame and the edge. Several first impact blocks are provided at the bottom of the frame, and several second impact blocks corresponding vertically to the first impact blocks are provided at the top of the base plate. First handles are provided on both sides of the edge, and second handles corresponding vertically to the first handles are provided on both sides of the frame.

[0004] When this device removes solidified concrete blocks by vibration, if the vibration frequency of the equipment is inappropriate or the concrete hardening is uneven, cracks or local fragmentation may appear inside the sample, or even cause edge chipping, destroying the integrity of the sample's shape. Such damage not only affects the structural stability of the concrete block itself, but may also cause deviations in the test data of key indicators such as strength and durability during subsequent testing, directly affecting the accuracy of the project quality assessment. In view of this, we provide a concrete sampler. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a concrete sampler.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete sampler, comprising a sample preparation component, wherein multiple sample preparation base plates are slidably connected to the inner wall of the sample preparation component, and multiple guide grooves are provided on both sides of the outer wall of the sample preparation component; a pressing top plate is sleeved on the outer wall of the sample preparation component, and multiple guide components are provided on the inner wall of the pressing top plate; a semi-circular ring lifting bracket is rotatably connected inside the sample preparation component, and multiple limiting ball heads are fixedly connected to both sides of the outer wall of the semi-circular ring lifting bracket; multiple vertical guide rails are fixedly connected to both sides of the inner wall of the sample preparation component, and multiple tension springs are sleeved at the bottom of the inner cavity of the sample preparation component.

[0007] As described above, the outer wall of the vertical guide rail passes through one side of the interior of the sample preparation base plate, and the interior side of the sample preparation base plate is slidably connected to the outer wall of the vertical guide rail.

[0008] As described above, the outer wall of the bottom end of the tension spring is welded to the bottom end of the inner wall of the sample preparation component, and the top end of the outer wall of the tension spring is welded to the bottom surface of the sample preparation base plate.

[0009] As described above, the outer wall of the bottom end of the limiting ball head is in close contact with and abuts against the bottom end of the inner wall of the sample preparation component.

[0010] As described above, the outer wall of the guide component is in close contact with the inner wall of the guide groove, and the outer wall of the guide component is slidably connected to the inner wall of the guide groove, and the top surface of the guide component abuts against the top of the inner wall of the guide groove.

[0011] The aforementioned semi-circular lifting bracket is a semi-circular ring structure with an upward opening, and circular caps are symmetrically arranged at both ends of the semi-circular lifting bracket.

[0012] As described above, the top surface of one side of the semi-circular lifting bracket abuts and fits against the center of the bottom surface of the sample preparation base plate, and the top surface of the other side of the semi-circular lifting bracket abuts and fits against one side of the bottom surface of the pressing top plate.

[0013] Compared with existing technologies, this concrete sampler has the following advantages:

[0014] I. This utility model involves introducing the concrete sample into the groove on the top surface of the sample preparation component. After it has completely solidified, the pressing plate is pressed vertically downward along the inner wall of the guide groove, and the sample preparation base plate is lifted along the outer wall of the vertical guide rail using the semi-circular lifting bracket. This allows the concrete sample to naturally separate from the inner wall of the sample preparation component. The entire demolding process requires no vibration or impact, and the force during the process is uniform and controllable. This effectively avoids edge cracking or internal cracking caused by vibration and impact in traditional devices, ensuring the integrity of the sample shape and preventing deviations in the sample's quality from affecting subsequent test results.

[0015] Second, after demolding, the tension spring automatically rebounds, driving the sample preparation base plate to reset downwards. The limiting ball head, through locking constraint, ensures that the sample preparation base plate accurately returns to its initial position each time it falls back, thus guaranteeing the accuracy of subsequent sample preparation.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0023] 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.

[0024] As shown in Figures 1-5, this utility model provides a technical solution: a concrete sampler, including a sample preparation component 1, multiple sample preparation base plates 2 are slidably connected to the inner wall of the sample preparation component 1, and multiple guide grooves 101 are provided on both sides of the outer wall of the sample preparation component 1. A pressing top plate 201 is sleeved on the outer wall of the sample preparation component 1, and multiple guide components 202 are provided on the inner wall of the pressing top plate 201. A semi-circular ring lifting bracket 203 is rotatably connected inside the sample preparation component 1, and multiple limiting ball heads 204 are fixedly connected to both sides of the outer wall of the semi-circular ring lifting bracket 203. Multiple vertical guide rails 102 are fixedly connected to both sides of the inner wall of the sample preparation component 1, and multiple tension springs 103 are sleeved at the bottom of the inner cavity of the sample preparation component 1.

[0025] The concrete sample to be prepared is introduced into the slot on the top surface of the sample preparation component 1. After it has completely solidified, the pressing top plate 201 is pressed vertically downward along the inner wall of the guide slide 101. The semi-circular lifting bracket 203 is used to lift the sample preparation base plate 2 along the outer wall of the vertical guide rail 102, so that the concrete sample can be naturally separated from the inner wall of the sample preparation component 1.

[0026] As shown in Figure 2, the outer wall of the vertical guide rail 102 passes through one side of the interior of the sample preparation base plate 2, and the interior side of the sample preparation base plate 2 is slidably connected to the outer wall of the vertical guide rail 102.

[0027] By extending through one side of the sample preparation base plate 2 via the outer wall of the vertical guide rail 102, the movement trajectory of the sample preparation base plate 2 within the sample preparation assembly 1 can be restricted, making the movement of the sample preparation base plate 2 as smooth and stable as possible.

[0028] As shown in Figure 3, the bottom outer wall of the tension spring 103 is welded to the bottom inner wall of the sample preparation component 1, and the top of the outer wall of the tension spring 103 is welded to the bottom surface of the sample preparation base plate 2.

[0029] After fixing the two ends of the tension spring 103 to the sample preparation assembly 1 and the sample preparation base plate 2 respectively, the sample preparation base plate 2 can be reset after sample preparation.

[0030] As shown in Figure 3, the outer wall of the bottom end of the limiting ball head 204 is in close contact with the bottom end of the inner wall of the sample preparation component 1 and they abut against each other.

[0031] The limiting ball head 204, through its locking constraint with the inner wall of the sample preparation component 1, can limit the lowest position of the sample preparation base plate 2 when it falls back.

[0032] As shown in Figure 5, the outer wall of the guide component 202 is tightly fitted to the inner wall of the guide groove 101, and the outer wall of the guide component 202 is slidably connected to the inner wall of the guide groove 101. The top surface of the guide component 202 abuts against the top of the inner wall of the guide groove 101.

[0033] By utilizing the cooperation between the guide component 202 and the guide groove 101, the highest and lowest positions of the pressing top plate 201 on the outer wall of the sample preparation component 1 can be limited, thus preventing it from detaching from the sample preparation component 1.

[0034] As shown in Figures 2-5, the semi-circular ring lifting bracket 203 is a semi-circular ring structure with an upward opening, and circular caps are symmetrically arranged at both ends of the semi-circular ring lifting bracket 203.

[0035] The semi-circular lifting bracket 203 has symmetrical circular caps on both ends, which makes it more stable and smooth when it comes into contact with the sample preparation base plate 2 and the outer wall of the pressing top plate 201.

[0036] As shown in Figures 2-5, the top surface of one side of the semi-circular lifting bracket 203 abuts against and fits against the center of the bottom surface of the sample preparation base plate 2, and the top surface of the other side of the semi-circular lifting bracket 203 abuts against and fits against one side of the bottom surface of the pressing top plate 201.

[0037] When the top plate 201 is pressed, the semi-circular lifting bracket 203 rotates and lifts the sample preparation base plate 2, so that the sample preparation base plate 2 rises evenly along the outer wall of the vertical guide rail 102.

[0038] Working principle: The vertical guide rail 102 penetrates one side of the sample preparation base plate 2 through its outer wall, restricting the movement trajectory of the sample preparation base plate 2 within the sample preparation assembly 1, ensuring smooth and stable movement. After fixing both ends of the tension spring 103 to the sample preparation assembly 1 and the sample preparation base plate 2 respectively, the sample preparation base plate 2 can be reset after sample preparation. The limiting ball head 204, through its locking constraint with the inner wall of the sample preparation assembly 1, restricts the sample preparation base plate 2 to its lowest position upon return. The cooperation between component 202 and guide groove 101 can limit the highest and lowest positions of pressing top plate 201 on the outer wall of sample preparation component 1, preventing it from detaching from sample preparation component 1. The semi-circular ring lifting bracket 203 is symmetrically provided with circular caps at both ends, which can make it more stable and smooth when in contact with sample preparation base plate 2 and outer wall of pressing top plate 201. When pressing top plate 201 applies force, semi-circular ring lifting bracket 203 rotates and lifts sample preparation base plate 2, so that sample preparation base plate 2 rises evenly along the outer wall of vertical guide rail 102.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
