DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Example 1.

[0031] like Figure 1-9 As shown, a steel bar raw material sampling tool provided by the present invention includes a steel bar cutting machine 1 with a steel bar cutting machine blade 4 and a wireless control switch 3, and also includes a plurality of height-adjustable brackets 11 distributed side by side, an arc-shaped support plate 6 arranged on the height-adjustable bracket 11, with its head located directly below the steel bar cutting machine blade 3 and used for supporting the sampling steel bar 19, and a linkage mechanism arranged on the height-adjustable bracket 11, abutting against the sampling steel bar 19, and used for triggering the action of the wireless control switch 3 after the sampling steel bar 19 reaches the sampling length; the arc-shaped support plate 6 is provided with a scale 5 along its length direction.

[0032] The invention has a simple structure, a scientific and reasonable design, and is easy to use, and can effectively improve the sampling efficiency and sample quality of steel bar raw materials and reduce human resource consumption.

[0033] The present invention tailors a piece of arc-shaped steel plate with scales as an arc-shaped support plate for steel bars according to the sampling length of the steel bar raw material, and arranges a retractable and adjustable support frame (height-adjustable support frame) at the lower part of the arc-shaped support plate. Since the heights of the blades of the steel bar cutting machines on the construction site are different, the height-adjustable support frame can be adjusted in real time according to the position of the blades of the steel bar cutting machines, and the sampling length of the steel bar raw material is fixed. When the steel bar raw material passes through the blades of the steel bar cutting machines and reaches the upper part of the arc-shaped support plate, the end of the steel bar will push the sample baffle plate located above the arc-shaped support plate forward, and the forward movement of the sample baffle plate will compress the reset spring and drive the transmission mechanism to start moving. At the end of the spring stroke, the baffle plate on the transmission mechanism just reaches the stroke for driving the wireless control switch to act, and the wireless control switch starts the steel bar cutting machine to cut the steel bar raw material. At this time, the sample baffle plate is just located at the position of the steel bar sampling length on the arc-shaped support plate, and the cut steel bar raw material is the sampling specimen. After the sampling specimen is taken away, the reset spring will return to the initial position, thereby achieving the purpose of cyclic and reciprocating sampling. During the entire sampling process, the control of the length of the steel bar raw material specimen and the steel bar cutting machine does not require manual assistance. Therefore, the present invention can quickly and accurately solve the technical problems of low efficiency of steel bar raw material sampling at the construction site and large steel bar sampling errors leading to unstable sampling quality.

[0034] Example 2.

[0035] like Figure 1-9 As shown, a steel bar raw material sampling tool provided by the present invention includes a steel bar cutting machine 1 with a steel bar cutting machine blade 4 and a wireless control switch 3, and also includes a plurality of height-adjustable brackets 11 distributed side by side, an arc-shaped support plate 6 arranged on the height-adjustable bracket 11, with its head located directly below the steel bar cutting machine blade 3 and used for supporting the sampling steel bar 19, and a linkage mechanism arranged on the height-adjustable bracket 11, abutting against the sampling steel bar 19, and used for triggering the action of the wireless control switch 3 after the sampling steel bar 19 reaches the sampling length; the arc-shaped support plate 6 is provided with a scale 5 along its length direction.

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

[0037] Based on Example 1, this Example 2 provides a more preferred structure of the linkage mechanism, specifically: the linkage mechanism includes a pair of brackets 21 installed on two height-adjustable brackets 11, a sample baffle 18 slidably installed on the pair of brackets 21 and adapted to the sampled steel bars 19 on the arc-shaped support plate 6, and a transmission mechanism connected between the sample baffle 18 and the wireless control switch 3. After the sampled steel bar reaches the arc-shaped support plate 6 under the action of the steel bar cutting machine 1, it continues to move forward and presses against the sample baffle 18, and then continues to move forward and pushes the sample baffle 18 forward. The sample baffle 18 drives the transmission mechanism to operate. When the sampled steel bar reaches the sampling length position, the transmission mechanism runs to a stroke that just triggers the action of the wireless control switch 3, so the wireless control switch 3 starts the steel bar cutting machine 1 and cuts the sampled steel bar 19. The process is simple, fast and efficient, and the sampling quality is stable.

[0038] Example 3.

[0039] like Figure 1-9 As shown, a steel bar raw material sampling tool provided by the present invention includes a steel bar cutting machine 1 with a steel bar cutting machine blade 4 and a wireless control switch 3, and also includes a plurality of height-adjustable brackets 11 distributed side by side, an arc-shaped support plate 6 arranged on the height-adjustable bracket 11, with its head located directly below the steel bar cutting machine blade 3 and used for supporting the sampling steel bar 19, and a linkage mechanism arranged on the height-adjustable bracket 11, abutting against the sampling steel bar 19, and used for triggering the action of the wireless control switch 3 after the sampling steel bar 19 reaches the sampling length; the arc-shaped support plate 6 is provided with a scale 5 along its length direction.

After the sampling steel bar reaches the arc-shaped support plate 6 under the action of the steel bar cutting machine 1, it continues to move forward and presses against the sample baffle 18, and then continues to move forward and pushes the sample baffle 18 forward. The sample baffle 18 drives the rack 9 forward, and the rack 9 meshes with the gear plate 8, driving the gear plate 8 to rotate. The gear plate 8 meshes with the transmission rod 26, thereby driving the transmission rod 26 to run in the opposite direction of the running direction of the sampling steel bar 19. When the sampling steel bar reaches the sampling length position, the transmission rod 26 runs to a stroke that just triggers the action of the wireless control switch 3, so the wireless control switch 3 starts the steel bar cutting machine 1 and cuts the sampling steel bar 19. The process is simple, fast and efficient, and the sampling quality is stable. A rotating shaft 20 is provided on the supporting crossbar 10, and the gear plate 8 is rotatably installed on the rotating shaft 20.

At the end of the spring stroke, the baffle on the transmission mechanism just reaches the stroke that drives the wireless control switch to operate. The wireless control switch starts the steel bar cutting machine to cut the steel bar raw material. At this time, the sample baffle is just located at the position of the steel bar sampling length on the arc-shaped support plate. The cut steel bar raw material is the sampling specimen. After the sampling specimen is taken away, the reset spring will return to the initial position, thereby achieving the purpose of cyclic and reciprocating sampling. During the entire sampling process, the control of the length of the steel bar raw material specimen and the steel bar cutting machine does not require manual assistance. Therefore, the present invention can quickly and accurately solve the technical problems of low efficiency of steel bar raw material sampling at the construction site and large steel bar sampling errors leading to unstable sampling quality.

[0076] Example 10.

[0077] like Figure 1-9 As shown, a steel bar raw material sampling tool provided by the present invention includes a steel bar cutting machine 1 with a steel bar cutting machine blade 4 and a wireless control switch 3, and also includes a plurality of height-adjustable brackets 11 distributed side by side, an arc-shaped support plate 6 arranged on the height-adjustable bracket 11, with its head located directly below the steel bar cutting machine blade 3 and used for supporting the sampling steel bar 19, and a linkage mechanism arranged on the height-adjustable bracket 11, abutting against the sampling steel bar 19, and used for triggering the action of the wireless control switch 3 after the sampling steel bar 19 reaches the sampling length; the arc-shaped support plate 6 is provided with 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 supporting cross bar 10 for supporting the arc-shaped support plate 6; the pair of rectangular inner tubes 12 are respectively welded to the two ends of the supporting cross bar 10, and the pair of rectangular inner tubes 12 are respectively inserted 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 slide groove 13 corresponding to the threaded through hole 25 is opened on the rectangular inner tube 12, the screw end of the bolt 14 passes through the threaded through hole 25 and presses against the slide groove 13, and a rectangular base 17 is welded to the bottom of the rectangular outer tube 15.

[0080] On the basis of Example 9, this Example 10 provides a more preferred structure of the fastening mechanism, specifically: the fastening mechanism includes a threaded through hole 25 provided on the rectangular outer tube 15, a bolt 14 threadedly connected to the threaded through hole 25, a slide groove 13 corresponding to the threaded through hole 25 provided on the rectangular inner tube 12, the screw end of the bolt 14 passes through the threaded through hole 25 and abuts against the slide groove 13, and a rectangular base 17 is welded to the bottom of the rectangular outer tube 15. The rectangular inner tube 12 can be freely telescopically adjusted in the rectangular outer tube 15. When adjusted to a suitable height, the bolt 14 is tightened, and the screw end of the bolt 14 abuts against the slide groove 13 to fix the rectangular inner tube 12 in the rectangular outer tube 15. Other operations of steel bar sampling can be performed. The present invention is provided with a telescopically adjustable height-adjustable bracket at the lower part of the arc-shaped support plate. Since the height of the blade of the steel bar cutting machine at the construction site is different, the height-adjustable bracket can be adjusted in real time according to the position of the blade of the steel bar cutting machine. In this way, the present invention can be applied to the sampling operations of different steel bar cutting machines, which can effectively expand the scope of application of the present invention.

[0081] The invention has a simple structure, a scientific and reasonable design, and is easy to use, and can effectively improve the sampling efficiency and sample quality of steel bar raw materials and reduce human resource consumption.

[0082] The present invention tailors a piece of arc-shaped steel plate with scales as an arc-shaped support plate for steel bars according to the sampling length of the steel bar raw material, and arranges a retractable and adjustable support frame (height-adjustable support frame) at the lower part of the arc-shaped support plate. Since the heights of the blades of the steel bar cutting machines on the construction site are different, the height-adjustable support frame can be adjusted in real time according to the position of the blades of the steel bar cutting machines, and the sampling length of the steel bar raw material is fixed. When the steel bar raw material passes through the blades of the steel bar cutting machines and reaches the upper part of the arc-shaped support plate, the end of the steel bar will push the sample baffle plate located above the arc-shaped support plate forward, and the forward movement of the sample baffle plate will compress the reset spring and drive the transmission mechanism to start moving. At the end of the spring stroke, the baffle plate on the transmission mechanism just reaches the stroke for driving the wireless control switch to act, and the wireless control switch starts the steel bar cutting machine to cut the steel bar raw material. At this time, the sample baffle plate is just located at the position of the steel bar sampling length on the arc-shaped support plate, and the cut steel bar raw material is the sampling specimen. After the sampling specimen is taken away, the reset spring will return to the initial position, thereby achieving the purpose of cyclic and reciprocating sampling. During the entire sampling process, the control of the length of the steel bar raw material specimen and the steel bar cutting machine does not require manual assistance. Therefore, the present invention can quickly and accurately solve the technical problems of low efficiency of steel bar raw material sampling at the construction site and large steel bar sampling errors leading to unstable sampling quality.

[0083] Finally, it should be noted that the above embodiments are only preferred embodiments of the present invention to illustrate the technical solution of the present invention, but not to limit it, and certainly not to limit the patent scope of the present invention. Any changes or modifications that have no substantial significance on the main design concept and spirit of the present invention, which solve technical problems consistent with the present invention, should be included in the protection scope of the present invention; in addition, the direct or indirect application of the technical solution of the present invention in other related technical fields should also be included in the patent protection scope of the present invention.
