Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and more specifically, it relates to a portable on-site testing and inspection device. Background Technology

[0002] With increasingly stringent requirements for construction processes at construction sites, relevant construction companies have reached unprecedented levels of quality control. Tensile strength, as one of the key indicators for measuring a material's ability to resist deformation and eventual failure under external forces, is crucial. When metals and other materials are subjected to external forces, their deformation and eventual fracture follow certain physical laws. The tensile test process involves carefully processing metal materials into specimens that meet specific specifications. These specimens are then placed in advanced tensile testing and inspection instruments and subjected to gradually increasing tensile forces until the specimen eventually fractures. Therefore, a portable on-site testing and inspection device is needed to test and inspect the strength of reinforcing bars.

[0003] Existing portable field testing and inspection devices have several drawbacks. During the tensile testing of reinforcing bars, debris ejected from the device can easily cause safety accidents. Furthermore, the device's fixing points are prone to detachment during tensile testing, affecting the testing results. The device's anti-detachment effect needs to be improved. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a portable on-site testing and inspection device to solve the issues that, during existing tensile testing of reinforcing bars, debris ejected can easily cause safety accidents; the device's fixing points are prone to detachment during tensile testing of reinforcing bars, affecting the device's testing effectiveness; and the device's anti-detachment effect needs improvement.

[0005] This utility model of portable on-site testing and inspection device is achieved through the following specific technical means:

[0006] A portable field testing device includes a base and a mounting base;

[0007] A set of hydraulic telescopic rods is fixedly installed on the top of the fixed base. A set of push plates is fixedly installed on the outer end of the drive shaft of the hydraulic telescopic rods. There are two sets of mounting bases in total. One set of mounting bases is slidably installed on the left end of the fixed base, and the other set of mounting bases is snapped on the right end of the fixed base. A set of telescopic spring rods is also fixedly installed on the left end of the fixed base. Two sets of movable frames are threaded on the top of the mounting base. A set of arc-shaped blocks is fixedly installed on the top of the movable frames. A set of fixed blocks slides obliquely on the inner end of the arc-shaped blocks. Anti-slip teeth are fixedly installed on the outer end of the fixed blocks. The left end of the push plate is in contact with the right end face of the left mounting base. Reinforcing bars are fixedly installed between the fixed blocks.

[0008] In at least some embodiments, a set of guide rods is fixedly installed on the top of the mounting base, and a set of guide holes are opened at the inner end of the movable frame, and the guide holes at the inner end of the movable frame are slidably installed on the guide rods at the top of the mounting base.

[0009] In at least some embodiments, a set of support rods is fixedly installed at the inner end of the arc-shaped block, the support rods are inclined, and a set of connecting plates is fixedly installed at the outer end of the fixed block. The connecting plates are provided with sliding holes, and the sliding holes of the connecting plates at the outer end of the fixed block are slidably installed on the support rods at the inner end of the arc-shaped block.

[0010] In at least some embodiments, the left end of the fixed base is provided with a guide groove, the right end of the fixed base is provided with a positioning slot, the bottom of the mounting base is fixedly installed with a guide block, and the guide block on the left mounting base is slidably installed on the guide groove at the left end of the fixed base, and the guide block on the right mounting base is snapped into the positioning slot on the fixed base and fixedly connected together by bolts.

[0011] In at least some embodiments, a set of elastic elements is sleeved on the support rod at the inner end of the arc-shaped block, and the outer end of the elastic elements is in contact with the inner end face of the connecting plate on the fixed block.

[0012] In at least some embodiments, a set of double-ended screws is rotatably mounted on the mounting base, and a set of threaded holes are opened at the outer end of the movable frame, and the threaded holes at the outer end of the movable frame are respectively threaded onto the two ends of the double-ended screws on the mounting base.

[0013] A portable field testing device includes a base and a portable field testing device. A set of protective housings is rotatably mounted on the outer end of the base. The protective housings are transparent and a controller is also mounted on the protective housings.

[0014] Compared with the prior art, the portable field testing and detection device of this utility model has the following advantages:

[0015] The mounting base, in conjunction with the protective housing, facilitates the sliding installation of the guide block on the left mounting base onto the guide groove at the left end of the fixed base. The guide block on the right mounting base engages with the positioning slot on the fixed base. After both ends of the rebar are secured, the hydraulic telescopic rod pushes the left mounting base outward via the push plate to perform a tensile test on the rebar. The protective housing at the outer end of the base protects the device during testing, preventing debris from flying out during the tensile test and causing safety accidents. The fixed blocks are slidably installed onto the guide rod at the top of the mounting base via the guide hole at the inner end of the moving frame. The threaded holes at the outer end of the moving frame are threaded onto both ends of the double-ended screw on the mounting base. Rotating the double-ended screw moves the fixed blocks on the two sets of arc-shaped blocks inward for tensile testing. Conversely, moving the arc-shaped blocks outward causes the fixed blocks to move inward relative to each other, further clamping and securing the rebar, improving the device's fixation effect and providing better anti-detachment performance.

[0028] A portable field testing device includes a base 5 and a portable field testing device. A set of protective housings 501 are rotatably mounted on the outer end of the base 5. The protective housings 501 are transparent and a controller is also mounted on them. A guide groove 101 is provided on the left end of the fixed base 1, and a positioning slot 103 is provided on the right end of the fixed base 1. A guide block 201 is fixedly mounted on the bottom of the mounting base 2. The guide block 201 on the left side of the mounting base 2 is slidably mounted on the guide groove 101 on the left end of the fixed base 1, and the guide block 201 on the right side of the mounting base 2 is engaged in the positioning slot 103 on the fixed base 1. The components are fixed together with bolts. Specifically, the guide block 201 on the left mounting base 2 is slidably installed on the guide groove 101 at the left end of the fixed base 1, and the guide block 201 on the right mounting base 2 is snapped into the positioning groove 103 on the fixed base 1. After both ends of the reinforcing bar 4 are fixed, the hydraulic telescopic rod 3 pushes the left mounting base 2 outward through the push plate 301 to conduct a tensile test on the reinforcing bar 4. The protective shell 501 at the outer end of the base 5 can protect the device during the test, preventing the safety accident caused by debris jumping out during the tensile test of the reinforcing bar 4.

[0029] Example 2: Based on Example 1, as follows Figures 4 to 6As shown, a set of guide rods 202 are fixedly installed on the top of the mounting base 2. A set of guide holes 2041 are opened at the inner end of the movable frame 204, and the guide holes 2041 at the inner end of the movable frame 204 are slidably installed on the guide rods 202 at the top of the mounting base 2. A set of double-ended screws 203 are rotatably installed on the mounting base 2. A set of threaded holes 2042 are opened at the outer end of the movable frame 204, and the threaded holes 2042 at the outer end of the movable frame 204 are threaded onto the mounting base 2. At both ends of the double-ended screw 203, a set of support rods 2051 are fixedly installed at the inner end of the arc-shaped block 205. The support rods 2051 are inclined. A set of connecting plates 2062 are fixedly installed at the outer end of the fixing block 206. The connecting plates 2062 have sliding holes, and the sliding holes of the connecting plates 2062 at the outer end of the fixing block 206 are slidably installed on the support rods 2051 at the inner end of the arc-shaped block 205. A set of elastic elements 2052 are sleeved on the support rods 2051 at the inner end of the arc-shaped block 205. The outer end of the elastic element 2052 contacts the inner end face of the connecting plate 2062 on the fixed block 206. Specifically, the guide hole 2041 at the inner end of the movable frame 204 is slidably installed on the guide rod 202 at the top of the mounting base 2, and the threaded hole 2042 at the outer end of the movable frame 204 is threaded onto both ends of the double-ended screw 203 on the mounting base 2. Rotating the double-ended screw 203 causes the fixed blocks 206 on the two sets of arc-shaped blocks 205 to move inward to fix the reinforcing bar 4. The sliding hole of the connecting plate 2062 at the outer end of the fixing block 206 is slidably installed on the support rod 2051 at the inner end of the arc-shaped block 205, and the support rod 2051 is inclined. With the cooperation of the elastic element 2052 on the support rod 2051, when the device performs a tensile test on the reinforcing bar 4, the arc-shaped block 205 moves outward, which allows the fixing block 206 to move inward relatively, so as to further clamp and fix the reinforcing bar 4, further improve the fixing effect of the device, and have a better anti-detachment effect.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In use, after both ends of the reinforcing bar 4 are fixed, the hydraulic telescopic rod 3 pushes the left mounting base 2 outward through the push plate 301. In conjunction with the pressure sensor at the left end of the push plate 301, a tensile test is performed on the reinforcing bar 4. The protective shell 501 at the outer end of the base 5 provides protection for the device during testing. When the double-headed screw 203 is rotated to move the fixing blocks 206 on the two sets of arc blocks 205 inward to perform a tensile test on the reinforcing bar 4, the arc blocks 205 move outward, which causes the fixing blocks 206 to move inward relative to each other, further clamping and fixing the reinforcing bar 4, further improving the fixing effect of the device, and having a better anti-detachment effect.
