[0002] Reinforcing steel reinforcement is an indispensable part of engineering construction, widely used in building construction, highway engineering, bridge engineering, and municipal public works projects. Sampling and testing of raw reinforcing steel is a crucial step in verifying whether it meets engineering construction standards. Therefore, the sampling and testing of raw reinforcing steel is closely related to the construction quality and safety of the project. Traditional reinforcing steel sampling methods, however, suffer from drawbacks such as long sampling cycles, low sampling efficiency, and unsatisfactory sample quality upon arrival at the site. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tool for sampling steel reinforcement raw materials, so as to at least solve some of the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A steel bar raw material sampling tool includes a steel bar cutter with a steel bar cutting blade and a wireless control switch, several height-adjustable supports arranged side by side, an arc-shaped support plate mounted on the height-adjustable supports with its head located directly below the steel bar cutting blade for supporting the sampled steel bar, and a linkage mechanism mounted on the height-adjustable supports, abutting against the sampled steel bar, for triggering the wireless control switch after the sampled steel bar reaches the sampling length; the arc-shaped support plate has graduations along its length.

[0006] Furthermore, the linkage mechanism includes a pair of brackets mounted on two height-adjustable supports, a sample baffle slidably mounted on the pair of brackets and adapted to the sampling steel bars on the arc-shaped support plate, and a transmission mechanism connecting the sample baffle and the wireless control switch.

[0007] Furthermore, the transmission mechanism includes a gear disk rotatably mounted on a height-adjustable bracket, a rack mounted on a sample baffle and meshing with one side of the gear disk, and a transmission rod with one end meshing with the other side of the gear disk and the other end connected to a wireless control switch; one end of the transmission rod is provided with teeth that mesh with the gear disk.

[0008] Furthermore, the wireless control switch is connected to a link B, the transmission rod is connected to a baffle, and the link B is connected to the baffle; there are two transmission mechanisms, with two transmission rods respectively connected to both ends of the baffle.

[0009] Furthermore, the height-adjustable bracket is equipped with guide blocks, and the transmission rod slides through the guide blocks. There are at least two guide blocks.

[0010] Furthermore, the support includes two supports respectively mounted on two height-adjustable supports, and connecting rods A respectively mounted on the two supports at both ends; a pair of through holes are provided on the sample baffle, and the two connecting rods A are respectively slidably inserted into one of the through holes.

[0011] Furthermore, the end of the sampling steel bar abuts against the sample baffle and can push the sample baffle to slide along the length of connecting rod A.

[0012] Furthermore, the support is equipped with a reset mechanism, which includes a reset spring that passes through the connecting rod A. One end of the reset spring is connected to the sample baffle, and the other end is connected to the corresponding support.

[0013] Furthermore, the height-adjustable bracket includes a pair of rectangular outer tubes, a pair of rectangular inner tubes, and a support crossbar for supporting the arc-shaped support plate; the pair of rectangular inner tubes are respectively welded to both ends of the support crossbar, and the pair of rectangular inner tubes are respectively fitted into the two rectangular outer tubes, with a fastening mechanism between the rectangular inner tubes and the rectangular outer tubes.

[0014] Furthermore, the fastening mechanism includes a threaded through hole on the rectangular outer tube, a bolt threaded into the threaded through hole, a groove on the rectangular inner tube corresponding to the threaded through hole, the end of the bolt thread passing through the threaded through hole and abutting against the groove, and a rectangular base welded to the bottom of the rectangular outer tube.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model has a simple structure, a scientific and reasonable design, and is easy to use. It can effectively improve the sampling efficiency and sample quality of steel reinforcement materials and reduce the consumption of human resources.

[0017] This invention features a custom-designed, graduated arc-shaped steel plate as a support plate for the reinforcing steel bars, with an adjustable support frame (height-adjustable bracket) at the bottom. Since the height of the cutting blades of the reinforcing steel bars varies at construction sites, the height-adjustable bracket can be adjusted in real-time according to the position of the blades. Since the sampling length of the reinforcing steel bars is fixed, when the steel bar reaches the upper part of the arc-shaped support plate through the cutting blades, the end of the steel bar pushes the sample baffle above the arc-shaped support plate forward. This forward movement of the sample baffle compresses the return spring and drives the transmission mechanism. At the end of the spring's stroke, the baffle on the transmission mechanism reaches the stroke required to activate the wireless control switch. The wireless control switch then activates the reinforcing steel bar cutter, cutting the steel bar. At this point, the sample baffle is positioned at the sampling length on the arc-shaped support plate, and the cut steel bar becomes the sample specimen. After the sample specimen is removed, the return spring returns to its initial position, thus achieving the purpose of cyclical and reciprocating sampling. Throughout the sampling process, the length of the steel reinforcement specimens and the control of the steel reinforcement cutting machine do not require manual assistance. Therefore, this invention can quickly and accurately solve the technical problems of low sampling efficiency and large sampling errors in steel reinforcement at construction sites, which lead to unstable sampling quality.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example 1.

[0031] like Figure 1-9 As shown, the present invention provides a steel bar raw material sampling tool, including a steel bar cutter 1 with a steel bar cutting blade 4 and a wireless control switch 3, and several height-adjustable supports 11 arranged side by side, an arc-shaped support plate 6 mounted on the height-adjustable support 11 with its head located directly below the steel bar cutting blade 4 for supporting the sampled steel bar 19, and a linkage mechanism mounted on the height-adjustable support 11, abutting against the sampled steel bar 19, for triggering the wireless control switch 3 after the sampled steel bar 19 reaches the sampling length; the arc-shaped support plate 6 has a scale 5 along its length direction.

[0032] This utility model has a simple structure, a scientific and reasonable design, and is easy to use. It can effectively improve the sampling efficiency and sample quality of steel reinforcement materials and reduce the consumption of human resources.

[0033] This invention features a custom-designed, graduated arc-shaped steel plate as a support plate for the reinforcing steel bars, with an adjustable support frame (height-adjustable bracket) at the bottom. Since the height of the cutting blades of the reinforcing steel bars varies at construction sites, the height-adjustable bracket can be adjusted in real-time according to the position of the blades. Since the sampling length of the reinforcing steel bars is fixed, when the steel bar reaches the upper part of the arc-shaped support plate through the cutting blades, the end of the steel bar pushes the sample baffle above the arc-shaped support plate forward. This forward movement of the sample baffle compresses the return spring and drives the transmission mechanism. At the end of the spring's stroke, the baffle on the transmission mechanism reaches the stroke required to activate the wireless control switch. The wireless control switch then activates the reinforcing steel bar cutter, cutting the steel bar. At this point, the sample baffle is positioned at the sampling length on the arc-shaped support plate, and the cut steel bar becomes the sample specimen. After the sample specimen is removed, the return spring returns to its initial position, thus achieving the purpose of cyclical and reciprocating sampling. Throughout the sampling process, the length of the steel reinforcement specimens and the control of the steel reinforcement cutting machine do not require manual assistance. Therefore, this invention can quickly and accurately solve the technical problems of low sampling efficiency and large sampling errors in steel reinforcement at construction sites, which lead to unstable sampling quality.

[0034] Example 2.

[0035] like Figure 1-9 As shown, the present invention provides a steel bar raw material sampling tool, including a steel bar cutter 1 with a steel bar cutting blade 4 and a wireless control switch 3, and several height-adjustable supports 11 arranged side by side, an arc-shaped support plate 6 mounted on the height-adjustable support 11 with its head located directly below the steel bar cutting blade 4 for supporting the sampled steel bar 19, and a linkage mechanism mounted on the height-adjustable support 11, abutting against the sampled steel bar 19, for triggering the wireless control switch 3 after the sampled steel bar 19 reaches the sampling length; the arc-shaped support plate 6 has a scale 5 along its length direction.

[0036] The linkage mechanism includes a pair of brackets 21 mounted on two height-adjustable brackets 11, a sample baffle 18 slidably mounted on the pair of brackets 21 and adapted to the sampling steel bar 19 on the arc-shaped support plate 6, and a transmission mechanism connecting the sample baffle 18 and the wireless control switch 3.

[0037] Based on Embodiment 1, this Embodiment 2 provides a more preferred structure for the linkage mechanism. Specifically, the linkage mechanism includes a pair of brackets 21 mounted on two height-adjustable supports 11, a sample baffle 18 slidably mounted on the pair of brackets 21 and adapted to the sampling steel bar 19 on the arc-shaped support plate 6, and a transmission mechanism connecting the sample baffle 18 and the wireless control switch 3. After the sampling steel bar reaches the arc-shaped support plate 6 under the action of the steel bar cutter 1, it continues to advance and abuts against the sample baffle 18. It then continues to advance and pushes the sample baffle 18 forward. The sample baffle 18 drives the transmission mechanism. When the sampling steel bar reaches the sampling length position, the transmission mechanism runs to the stroke that just triggers the action of the wireless control switch 3. Then, the wireless control switch 3 starts the steel bar cutter 1 and cuts the sampling steel bar 19. The process is simple, fast, efficient, and the sampling quality is stable.

After the sampled rebar reaches the arc-shaped support plate 6 under the action of the rebar cutter 1, it continues to advance and abuts against the sample baffle 18. It then continues to advance, pushing the sample baffle 18 forward. The sample baffle 18 drives the rack 9 forward, which meshes with the gear disc 8, causing the gear disc 8 to rotate. The gear disc 8 meshes with the transmission rod 26, thus driving the transmission rod 26 to move in the opposite direction to the sampled rebar 19. When the sampled rebar reaches the sampling length position, the transmission rod 26 moves to the stroke that just triggers the wireless control switch 3. The wireless control switch 3 then starts the rebar cutter 1 and cuts the sampled rebar 19. The process is simple, fast, efficient, and the sampling quality is stable. A rotating shaft 20 is provided on the support crossbar 10, and the gear disc 8 is rotatably mounted on the rotating shaft 20. A limiting plate 29 is provided at the top of the rotating shaft 20 to prevent the gear disc 8 from slipping off the rotating shaft 20.

There are two transmission mechanisms, and the two transmission rods 26 are respectively connected to the two ends of the baffle 2.

[0053] The height-adjustable bracket 11 is provided with guide blocks 7, and the transmission rod 26 slides through the guide blocks 7. There are at least two guide blocks 7. The sample baffle 18 is provided with a sample baffle through hole 30 that matches the transmission rod 26, and the transmission rod 26 slides through the sample baffle through hole 30.

[0054] Based on Example 3, this embodiment 5 provides a more preferred connection structure between the transmission rod 26 and the height-adjustable bracket 11.

During the sampling process, when the steel bar reaches the upper part of the arc-shaped support plate through the cutting edge of the steel bar cutter, the end of the steel bar pushes the sample baffle on the arc-shaped support plate to slide along the length of the connecting rod A23, thereby driving the transmission mechanism to operate.

[0060] Example 7.

[0064] The end of the sampling steel bar 19 abuts against the sample baffle 18 and can push the sample baffle 18 to slide along the length of the connecting rod A23.

[0065] Based on Example 6, Example 7 provides a more preferred connection structure between the sampling steel bar 19 and the sample baffle 18. Specifically, the end of the sampling steel bar 19 abuts against the sample baffle 18 and can push the sample baffle 18 to slide along the length direction of the connecting rod A23. Both ends of the sample baffle 18 are respectively inserted through corresponding through holes 24 on a connecting rod A23. During the sampling process, when the steel bar reaches the upper part of the arc-shaped support plate through the cutting edge of the steel bar cutter, the end of the steel bar pushes the sample baffle on the arc-shaped support plate to slide along the length direction of the connecting rod A23, thereby driving the transmission mechanism to operate.

[0066] Example 8.

[0067] like Figure 1-9 As shown, the present invention provides a steel bar raw material sampling tool, including a steel bar cutter 1 with a steel bar cutting blade 4 and a wireless control switch 3, and several height-adjustable supports 11 arranged side by side, an arc-shaped support plate 6 mounted on the height-adjustable support 11 with its head located directly below the steel bar cutting blade 4 for supporting the sampled steel bar 19, and a linkage mechanism mounted on the height-adjustable support 11, abutting against the sampled steel bar 19, for triggering the wireless control switch 3 after the sampled steel bar 19 reaches the sampling length; the arc-shaped support plate 6 has a scale 5 along its length direction.

[0068] The linkage mechanism includes a pair of brackets 21 mounted on two height-adjustable brackets 11, a sample baffle 18 slidably mounted on the pair of brackets 21 and adapted to the sampling steel bar 19 on the arc-shaped support plate 6, and a transmission mechanism connecting the sample baffle 18 and the wireless control switch 3.

[0071] Based on Embodiment 6, Embodiment 8 provides a more preferred structure for the support 21. Specifically, the support 21 is equipped with a reset mechanism, which includes a reset spring 16 passing through the connecting rod A23. One end of the reset spring 16 is connected to the sample baffle 18, and the other end is connected to the corresponding support 22. When the steel bar reaches the upper part of the arc-shaped support plate through the blade of the steel bar cutter, the end of the steel bar will push the sample baffle located above the arc-shaped support plate forward. The forward movement of the sample baffle will compress the reset spring and drive the transmission mechanism to start moving.

The wireless control switch starts the steel bar cutter to cut the steel bar. At this time, the sample baffle is just located at the sampling length of the steel bar on the arc-shaped support plate. The cut steel bar is the sampling specimen. After the sampling specimen is removed, the reset spring will return to the initial position, thereby achieving the purpose of cyclic and reciprocating sampling. Throughout the sampling process, the length of the steel reinforcement specimens and the control of the steel reinforcement cutting machine do not require manual assistance. Therefore, this invention can quickly and accurately solve the technical problems of low sampling efficiency and large sampling errors in steel reinforcement at construction sites, which lead to unstable sampling quality.

Specifically, the height-adjustable support 11 includes a pair of rectangular outer tubes 15, a pair of rectangular inner tubes 12, and a support crossbar 10 for supporting the arc-shaped support plate 6. The pair of rectangular inner tubes 12 are welded to both ends of the support crossbar 10, and the pair of rectangular inner tubes 12 are respectively fitted inside the two rectangular outer tubes 15. A fastening mechanism is provided between the rectangular inner tubes 12 and the rectangular outer tubes 15. The support 22 is installed on the support crossbar 10. The rectangular inner tubes 12 can freely extend and retract within the rectangular outer tubes 15. When adjusted to a suitable height, the rectangular inner tubes 12 are fixed inside the rectangular outer tubes 15 by the fastening mechanism. Other operations for rebar sampling can then be performed. This utility model features a telescopic and height-adjustable bracket at the bottom of the arc-shaped support plate. Since the height of the blade of the rebar cutter varies at the construction site, the height-adjustable bracket can be adjusted in real time according to the position of the blade. Thus, this utility model can be applied to the sampling operation of different rebar cutters, effectively expanding the scope of application of this utility model.

[0077] like Figure 1-9 As shown, the present invention provides a steel bar raw material sampling tool, including a steel bar cutter 1 with a steel bar cutting blade 4 and a wireless control switch 3, and several height-adjustable supports 11 arranged side by side, an arc-shaped support plate 6 mounted on the height-adjustable support 11 with its head located directly below the steel bar cutting blade 4 for supporting the sampled steel bar 19, and a linkage mechanism mounted on the height-adjustable support 11, abutting against the sampled steel bar 19, for triggering the wireless control switch 3 after the sampled steel bar 19 reaches the sampling length; the arc-shaped support plate 6 has a scale 5 along its length direction.

[0078] The height-adjustable bracket 11 includes a pair of rectangular outer tubes 15, a pair of rectangular inner tubes 12, and a support crossbar 10 for supporting the arc-shaped support plate 6; the pair of rectangular inner tubes 12 are respectively welded to both ends of the support crossbar 10, and the pair of rectangular inner tubes 12 are respectively fitted into the two rectangular outer tubes 15, and a fastening mechanism is provided between the rectangular inner tubes 12 and the rectangular outer tubes 15.

[0079] The fastening mechanism includes a threaded through hole 25 opened on the rectangular outer tube 15, a bolt 14 threadedly connected to the threaded through hole 25, a groove 13 corresponding to the threaded through hole 25 opened on the rectangular inner tube 12, the end of the bolt 14 passes through the threaded through hole 25 and abuts against the groove 13, and a rectangular base 17 is welded to the bottom of the rectangular outer tube 15.

[0080] Based on Embodiment 9, Embodiment 10 provides a more preferred structure for the fastening mechanism. Specifically, the fastening mechanism includes a threaded through hole 25 on the rectangular outer tube 15, a bolt 14 threaded into the threaded through hole 25, and a groove 13 on the rectangular inner tube 12 corresponding to the threaded through hole 25. The end of the bolt 14 passes through the threaded through hole 25 and abuts against the groove 13. A rectangular base 17 is welded to the bottom of the rectangular outer tube 15. The rectangular inner tube 12 can freely extend and retract within the rectangular outer tube 15. When adjusted to a suitable height, tightening the bolt 14, with the end of the bolt 14 abutting against the groove 13, fixes the rectangular inner tube 12 within the rectangular outer tube 15. This allows for other operations such as rebar sampling. This utility model features a telescopic and height-adjustable bracket at the bottom of the arc-shaped support plate. Since the height of the blade of the rebar cutter varies at the construction site, the height-adjustable bracket can be adjusted in real time according to the position of the blade. Thus, this utility model can be applied to the sampling operation of different rebar cutters, effectively expanding the scope of application of this utility model.

[0081] This utility model has a simple structure, a scientific and reasonable design, and is easy to use. It can effectively improve the sampling efficiency and sample quality of steel reinforcement materials and reduce the consumption of human resources.

[0082] This invention features a custom-designed, graduated arc-shaped steel plate as a support plate for the reinforcing steel bars, with an adjustable support frame (height-adjustable bracket) at the bottom. Since the height of the cutting blades of the reinforcing steel bars varies at construction sites, the height-adjustable bracket can be adjusted in real-time according to the position of the blades. Since the sampling length of the reinforcing steel bars is fixed, when the steel bar reaches the upper part of the arc-shaped support plate through the cutting blades, the end of the steel bar pushes the sample baffle above the arc-shaped support plate forward. This forward movement of the sample baffle compresses the return spring and drives the transmission mechanism. At the end of the spring's stroke, the baffle on the transmission mechanism reaches the stroke required to activate the wireless control switch. The wireless control switch then activates the reinforcing steel bar cutter, cutting the steel bar. At this point, the sample baffle is positioned at the sampling length on the arc-shaped support plate, and the cut steel bar becomes the sample specimen. After the sample specimen is removed, the return spring returns to its initial position, thus achieving the purpose of cyclical and reciprocating sampling. Throughout the sampling process, the length of the steel reinforcement specimens and the control of the steel reinforcement cutting machine do not require manual assistance. Therefore, this invention can quickly and accurately solve the technical problems of low sampling efficiency and large sampling errors in steel reinforcement at construction sites, which lead to unstable sampling quality.

[0083] Finally, it should be noted that the above embodiments are merely preferred embodiments used to illustrate the technical solution of this utility model, and are not intended to limit it, much less limit the patent scope of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but which still solve the same technical problem as this utility model, should be included within the protection scope of this utility model; in addition, the direct or indirect application of the technical solution of this utility model to other related technical fields are similarly included within the patent protection scope of this utility model.
