Description

Technical Field

[0001] This utility model relates to the field of concrete strength testing technology, and in particular to a concrete strength compressive crushing testing device. Background Technology

[0002] Concrete strength is one of the important indicators for evaluating concrete quality. Currently, commonly used methods for testing concrete strength include rebound hammer testing, ultrasonic testing, and core drilling. During pressure testing, multiple batches of test samples need to be manually loaded.

[0003] Existing concrete strength testing devices suffer from problems such as the need for manual operation of material feeding, which is time-consuming, labor-intensive, and has low testing efficiency.

[0004] Therefore, a concrete strength compressive crushing test device is needed. Utility Model Content

[0005] The present invention proposes a concrete strength compressive crushing test device, which solves the problems of existing concrete strength test devices that require manual operation for feeding, which is time-consuming, labor-intensive, and has low feeding and testing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A concrete strength compressive crushing test device includes a guide rail frame, a feeding rack welded to the top of the guide rail frame, and a test sample slidably placed on the top of the guide rail frame.

[0008] A slide rail is provided below the guide rail frame, a sliding frame is slidably installed on the outer side of the slide rail, several fixed shafts are installed on the top of the sliding frame, a push rod is rotatably installed in the middle of the fixed shaft, a rotating shaft is installed at the bottom of the sliding frame, and a control mechanism is rotatably connected to the outer side of the rotating shaft.

[0009] Preferably, a testing platform is fixed to the left end of the guide rail frame, a pressure detector is installed on the side of the testing platform, a translation mechanism is installed on the rear side of the testing platform, and a guide frame is integrally provided on the front side of the testing platform.

[0010] Preferably, the test samples are stacked vertically along the inside of the feed rack, and the test samples are slidably disposed between the test samples and the guide rail rack.

[0011] Preferably, the control mechanism includes a transmission rod, with a rotating rod rotatably connected to the end of the transmission rod, and the output end of the rotating rod connected to the tail end of the motor.

[0012] Preferably, the sliding frame forms a sliding structure between the slide rail and the guide rail frame, and the sliding frame forms a transmission structure between the transmission rod and the rotating rod, and the push rod forms a rotation structure between the fixed shaft and the sliding frame.

[0013] Preferably, the translation mechanism includes a hydraulic rod, the output end of which is connected to a push plate, and guide rods are symmetrically arranged at both ends of the rear side of the push plate.

[0014] Preferably, the push plate forms a sliding structure with the testing table via a hydraulic rod, and the guide rod and the push plate are integrally integrated.

[0015] This utility model proposes a concrete strength compressive crushing testing device. Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting up a control mechanism, the test items are placed sequentially inside the feed rack. When the bottom motor controls the rotating rod to drive the transmission rod, it can control the top sliding frame to move horizontally back and forth at a uniform speed along the inside of the slide rail. When the equipment moves to the left, the shorter side of the L-shaped push rod at the top moves to the left, pushing the test item to move horizontally to the left along the guide rail frame, completing the sequential feeding operation. At the same time, by moving the sliding frame in the opposite direction, the push rod at the top moves and rotates slightly around the fixed axis when the push rod contacts the next test item, so that the push rod passes around the next test item at the bottom to its rear. This ensures that the next test item can be pushed by the push rod when the equipment moves forward again, thus maintaining a stable feeding and testing operation of the test items and improving efficiency.

[0017] 2. By setting up a translation mechanism, when the test item is pushed to the top of the test table, it can be pressed down by a pressure detector. After the test is completed, the push plate is pushed forward by a hydraulic rod, so that the push plate pushes the test item on the top of the test table, thereby cleaning the surface of the test table. It can be used in conjunction with the conveying device to perform efficient and stable testing operations, which is more time-saving and labor-saving, and facilitates pressure testing operations.

Detailed Implementation

[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] Please see Figure 1-4 This utility model provides a technical solution: a concrete strength compressive crushing test device, including a guide rail frame 1, a feeding rack 2 welded to the top of the guide rail frame 1, and a test sample 3 slidably placed on the top of the guide rail frame 1;

[0025] A slide rail 4 is provided below the guide rail frame 1. A slide frame 5 is slidably installed on the outer side of the slide rail 4. Several fixed shafts 6 are installed on the top of the slide frame 5. A push rod 7 is rotatably installed in the middle of the fixed shaft 6. A rotating shaft 8 is installed at the bottom of the slide frame 5. A control mechanism 9 is rotatably connected to the outer side of the rotating shaft 8.

[0026] Furthermore, a testing platform 10 is fixed to the left end of the guide rail frame 1, a pressure detector 11 is installed on the side of the testing platform 10, a translation mechanism 12 is installed on the rear side of the testing platform 10, and a guide frame 13 is integrally provided on the front side of the testing platform 10.

[0027] Furthermore, the test items 3 are stacked vertically along the inside of the feed rack 2, and the test items 3 are slidably set between the guide rail frame 1, which facilitates automatic, uniform and continuous feeding and testing operations.

[0028] Furthermore, the control mechanism 9 includes a transmission rod 901, with a rotating rod 902 rotatably connected to the end of the transmission rod 901, and the output end of a motor 903 connected to the tail end of the rotating rod 902. By setting up the control mechanism 9, the test items 3 are placed sequentially inside the feed rack 2. When the bottom motor 903 controls the rotating rod 902 to drive the transmission rod 901, it can control the top sliding frame 5 to move horizontally back and forth at a uniform speed along the inside of the slide rail 4. When the equipment moves to the left, the shorter side of the L-shaped push rod 7 at the top moves to the left, pushing the test item 3 to move horizontally to the left along the guide rail frame, completing the sequential feeding operation. At the same time, by moving the sliding frame 5 in the opposite direction, the push rod 7 at the top moves and rotates slightly around the fixed axis 6 when the push rod 7 contacts the next test item 3, so that the push rod 7 passes around the next test item 3 at the bottom to its rear, ensuring that the next test item 3 can be pushed by the push rod 7 when the equipment moves forward again, thus maintaining the stable feeding and testing operation of the test items 3 and improving efficiency.

[0029] Furthermore, the sliding frame 5 forms a sliding structure with the guide rail 4 and the guide rail frame 1, and the sliding frame 5 forms a transmission structure with the transmission rod 901 and the rotating rod 902. The push rod 7 forms a rotation structure with the sliding frame 5 through the fixed shaft 6. This can control the top sliding frame 5 to move horizontally and reciprocally at a uniform speed along the inside of the guide rail 4, ensuring that when the equipment moves forward again, the push rod 7 can push the next inspection item 3, thus maintaining the stable feeding and inspection operation of the inspection item 3 and improving efficiency.

[0030] Furthermore, the translation mechanism 12 includes a hydraulic rod 1201, the output end of which is connected to a push plate 1202, and guide rods 1203 are symmetrically arranged at both ends of the rear side of the push plate 1202. By setting the translation mechanism 12, when the test item 3 is pushed to the top of the test table 10, it can be pressed down by the pressure detector 11. After the test is completed, the hydraulic rod 1201 pushes the push plate 1202 forward, so that the push plate 1201 pushes the test item 3 on the top of the test table 10, thereby cleaning the surface of the test table 10. It can cooperate with the conveying device to perform efficient and stable testing operations, which is more time-saving and labor-saving, and convenient for pressure testing operations.

[0031] Furthermore, the push plate 1202 forms a sliding structure with the test table 10 through the hydraulic rod 1201, and the guide rod 1203 is integrated with the push plate 1202. The push plate 1202 pushes the test item 3 on the top of the test table 10 to clean the surface of the test table 10, and can cooperate with the conveying device to perform efficient and stable testing operations.

[0032] Working principle: First, the test items 3 are placed sequentially inside the feed rack 2. When the bottom motor 903 controls the rotating rod 902 to drive the transmission rod 901, it can control the top sliding frame 5 to move horizontally back and forth at a uniform speed along the inside of the slide rail 4. When the equipment moves to the left, the shorter side of the L-shaped push rod 7 at the top moves to the left, pushing the test item 3 to move horizontally to the left along the guide rail frame 1, completing the sequential feeding operation. At the same time, the push rod 7 at the top moves by moving the sliding frame 5 in the opposite direction. When the push rod 7 contacts the next test item 3, it rotates slightly around the fixed axis 6, so that the push rod 7 passes around the next test item 3 at the bottom to its rear. This ensures that the next test item 3 can be pushed by the push rod 7 when the equipment moves forward again, thus maintaining the stable feeding and testing operation of the test items 3 and improving efficiency.

[0033] Next, when the test item 3 is pushed to the top of the test table 10, it can be pressed down by the pressure detector 11. After the test is completed, the hydraulic rod 1201 pushes the push plate 1202 forward, so that the push plate 1202 pushes the test item 3 on the top of the test table 10, thereby cleaning the surface of the test table 10. It can be used in conjunction with the conveying device to perform efficient and stable testing operations, which is more time-saving and labor-saving, and convenient for pressure testing operations.

[0034] 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.
