Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a fully automatic rapid sampling device for steel bar raw materials at a construction site. Background Art

[0002] With the continuous improvement of the intelligent level of the construction industry, the application of intelligent equipment in various types of engineering construction is becoming more and more extensive. As an indispensable part of construction projects, steel bar engineering has been widely used in the fields of housing construction, roads, bridges and municipal public works, and its performance directly affects the quality and safety of the project. During the construction process, sampling and testing of raw steel bars are usually performed to assess whether they meet the construction standards. Therefore, the sampling and testing of raw steel bars are closely related to the quality and safety of the project. However, traditional steel bar sampling methods are difficult to achieve fast, accurate and automated sampling when the steel bars arrive at the construction site, resulting in complicated operating procedures, low on-site sampling efficiency, long testing cycles, and a large amount of human resources. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a fully automatic rapid sampling device for steel bar raw materials at a construction site, so as to at least solve some of the above technical problems.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] A fully automatic rapid sampling device for steel bar raw materials at a construction site comprises a steel bar cutter with a steel bar cutter blade and a wireless control switch, the wireless control switch having a built-in wireless signal receiver, and further comprising a plurality of height-adjustable brackets distributed side by side, an arc-shaped support plate provided on the height-adjustable bracket with its head located directly below the steel bar cutter blade, and an automatic sample alignment device provided on two adjacent height-adjustable brackets, located at the tail ends of the arc-shaped support plates, and wirelessly connected to the wireless signal receiver on the wireless control switch, wherein the arc-shaped support plate is provided with a scale along its length.

[0006] Furthermore, the automatic sample positioning device includes a pair of brackets installed on two height-adjustable brackets, a sample baffle slidably installed on the pair of brackets and adapted to the sampling steel bars on the arc-shaped support plate, and a positioning mechanism provided on the pair of brackets for positioning the sample baffle; the positioning mechanism is wirelessly connected to the wireless signal receiver on the wireless control switch.

[0007] Furthermore, the bracket includes two supports respectively installed on two height-adjustable brackets, and connecting rods with both ends respectively installed on the two supports; a pair of through holes are opened on the sample baffle, and the two connecting rods are respectively slid through one through hole.

[0008] Furthermore, the positioning mechanism includes an infrared emitting device arranged on one support, and an infrared receiving device arranged on another support and adapted to the infrared emitting device; the infrared receiving device has a built-in wireless signal transmitter adapted to the wireless signal receiver, and the infrared emitting device and the infrared receiving device are respectively located on the two supports.

[0009] Furthermore, the sample baffle can slide freely along the length direction of the two connecting rods, and the sliding direction of the sample baffle is consistent with the length direction of the arc-shaped supporting plate.

[0010] Furthermore, when the sampling steel bar pushes the sample baffle to move along the length direction of the connecting rod to the sampling position of the sampling steel bar, the sample baffle is located between the infrared emitting device and the infrared receiving device.

[0011] Furthermore, a reset mechanism is provided on the bracket, which includes a reset spring passed through the connecting rod, one end of the reset spring is connected to the sample baffle, and the other end is connected to the corresponding support, and the sample baffle and the positioning mechanism are respectively arranged at both ends of the reset spring.

[0012] Furthermore, the height-adjustable bracket includes a pair of rectangular outer tubes, a pair of rectangular inner tubes, and a supporting cross bar for supporting the arc-shaped support plate; a pair of rectangular inner tubes are respectively welded to the two ends of the supporting cross bar, and a pair of rectangular inner tubes are respectively inserted into a rectangular outer tube, and a fastening mechanism is provided between the rectangular inner tube and the rectangular outer tube.

[0013] Furthermore, the fastening mechanism includes a threaded through hole opened on the rectangular outer tube, a bolt threadedly connected to the threaded through hole, a sliding groove corresponding to the threaded through hole opened on the rectangular inner tube, and the screw end of the bolt passes through the threaded through hole and presses against the sliding groove.

[0014] Furthermore, a rectangular base is welded to the bottom of the rectangular outer tube.

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

[0016] 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.

[0017] The present invention tailors a curved steel plate with a scale as a steel bar support plate according to the sampling length of the steel bar raw material, and provides a telescopically adjustable height-adjustable bracket at the lower part of the curved support plate. Since the height of the steel bar cutting machine blade is different on the construction site, the height-adjustable bracket can be adjusted in real time according to the position of the steel bar cutting machine blade. The sampling length of the steel bar raw material is fixed, and an infrared emitting device and a receiving device are installed on both sides of the scale position on the curved support plate that meets the standard sampling length. The receiving device has a built-in wireless signal transmitter. When the steel bar raw material passes through the steel bar cutting machine blade and reaches the upper part of the curved support plate, the end of the steel bar will push the sample baffle located on the curved support plate. The compressed return spring moves forward, and when the steel bar pushes the sample baffle to move to the scale position of the standard sampling length, the sample baffle will block the infrared beam emitted by the infrared ray. At this time, the infrared receiving device cannot receive the infrared light, and the built-in wireless signal transmitter of the infrared receiving device will send a signal to the built-in wireless signal receiver of the wireless control switch on the steel bar cutting machine. After receiving the signal through the wireless signal receiver, the wireless control switch controls the steel bar cutting machine to cut the steel bar. The cut steel bar raw material is the sampling specimen. After the sampling specimen is removed, the return spring will push the sample baffle back to its original position, thereby achieving the purpose of cyclic, reciprocating and automated sampling. During the entire sampling process, the control of the steel bar raw material specimen length and the steel bar cutting machine does not require manual assistance. Therefore, the above-mentioned fully automatic rapid sampling device can quickly, accurately and automatically solve the problem of steel bar raw material sampling at the construction site.

[0029] 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.

[0030] Example 2.

[0031] like Figures 1-6As shown, the present invention provides a fully automatic rapid sampling device for steel bar raw materials at a construction site, comprising a steel bar cutter 1 with a steel bar cutter blade 3 and a wireless control switch 2, wherein the wireless control switch 2 has a built-in wireless signal receiver 6. The device also includes a plurality of height-adjustable brackets 11 arranged side by side, an arc-shaped support plate 4 disposed on the height-adjustable brackets 11 with its head positioned directly below the steel bar cutter blade 3, and an automatic sample alignment device disposed on two adjacent height-adjustable brackets 11, located at the rear ends of the arc-shaped support plates 4, and wirelessly connected to the wireless signal receiver 6 on the wireless control switch 2.

[0032] The automatic sample positioning device includes a pair of brackets 21 installed on two height-adjustable brackets 11, a sample baffle 13 slidably installed on the pair of brackets 21 and adapted to the sampling steel bars 18 on the arc-shaped support plate 4, and a positioning mechanism provided on the pair of brackets 21 for positioning the sample baffle 13; the positioning mechanism is wirelessly connected to the wireless signal receiver 6 on the wireless control switch 2.

[0033] Based on Example 1, this Example 2 provides a more preferred structure of the automatic sample positioning device, specifically: the automatic sample positioning device includes a pair of brackets 21 installed on two height-adjustable brackets 11, a sample baffle 13 slidably installed on the pair of brackets 21 and adapted to the sampling steel bar 18 on the arc-shaped support plate 4, and a positioning mechanism provided on the pair of brackets 21 for positioning the sample baffle 13; the positioning mechanism is wirelessly connected to the wireless signal receiver 6 on the wireless control switch 2. During sampling, the sampling steel bar 18 pushes the sample baffle 13 to slide along the length direction of the arc-shaped support plate 4. When the positioning mechanism locates the sampling steel bar 18 to reach the sampling length position, it transmits the information to the wireless control switch 2 via a wireless signal. When the wireless control switch 2 receives the information, it controls the steel bar cutting machine 1 to cut the sampling steel bar 18, thereby obtaining a sampling steel bar whose sampling length meets the sampling requirements.

[0034] Example 3.

[0035] like Figures 1-6 As shown, the present invention provides a fully automatic rapid sampling device for steel bar raw materials at a construction site, comprising a steel bar cutter 1 with a steel bar cutter blade 3 and a wireless control switch 2, wherein the wireless control switch 2 has a built-in wireless signal receiver 6. The device also includes a plurality of height-adjustable brackets 11 arranged side by side, an arc-shaped support plate 4 disposed on the height-adjustable brackets 11 with its head positioned directly below the steel bar cutter blade 3, and an automatic sample alignment device disposed on two adjacent height-adjustable brackets 11, located at the rear ends of the arc-shaped support plates 4, and wirelessly connected to the wireless signal receiver 6 on the wireless control switch 2.

[0037] The bracket 21 includes two supports 22 respectively mounted on two height-adjustable brackets 11, and connecting rods 23 with both ends respectively mounted on the two supports 22; a pair of through holes 24 are opened on the sample baffle 13, and the two connecting rods 23 are respectively slidably passed through one through hole 24.

[0038] Based on Example 2, this Example 3 provides a more preferred structure for the bracket 21, specifically: the bracket 21 includes two supports 22 respectively mounted on two height-adjustable brackets 11, and a connecting rod 23 with two ends respectively mounted on the two supports 22; a pair of through holes 24 are formed on the sample baffle 13, and two connecting rods 23 are respectively slidably inserted into one through hole 24. The two ends of the sample baffle 13 are respectively inserted into a connecting rod 23 through corresponding through holes 24, and can slide freely along the length of the connecting rod 23. During the sampling process, when the raw steel bar passes through the blade of the steel bar cutting machine and reaches the upper part of the arc-shaped support plate, the end of the steel bar pushes the sample baffle located on the arc-shaped support plate to slide along the length of the connecting rod 23. When the positioning mechanism locates the sample bar 18 at the sampling length position through the sample baffle 13, the positioning mechanism transmits the information to the wireless control switch 2 via a wireless signal. When the wireless control switch 2 receives the information, it controls the steel bar cutting machine 1 to cut the sample bar 18, thereby obtaining a sample bar whose sampling length meets the sampling requirements.

[0039] Example 4.

[0040] like Figures 1-6 As shown, the present invention provides a fully automatic rapid sampling device for steel bar raw materials at a construction site, comprising a steel bar cutter 1 with a steel bar cutter blade 3 and a wireless control switch 2, wherein the wireless control switch 2 has a built-in wireless signal receiver 6. The device also includes a plurality of height-adjustable brackets 11 arranged side by side, an arc-shaped support plate 4 disposed on the height-adjustable brackets 11 with its head positioned directly below the steel bar cutter blade 3, and an automatic sample alignment device disposed on two adjacent height-adjustable brackets 11, located at the rear ends of the arc-shaped support plates 4, and wirelessly connected to the wireless signal receiver 6 on the wireless control switch 2. The arc-shaped support plates 4 are provided with scales 19 along their lengths.

[0041] The automatic sample positioning device includes a pair of brackets 21 installed on two height-adjustable brackets 11, a sample baffle 13 slidably installed on the pair of brackets 21 and adapted to the sampling steel bars 18 on the arc-shaped support plate 4, and a positioning mechanism provided on the pair of brackets 21 for positioning the sample baffle 13; the positioning mechanism is wirelessly connected to the wireless signal receiver 6 on the wireless control switch 2.

[0042] The bracket 21 includes two supports 22 respectively mounted on two height-adjustable brackets 11, and connecting rods 23 with both ends respectively mounted on the two supports 22; a pair of through holes 24 are opened on the sample baffle 13, and the two connecting rods 23 are respectively slidably passed through one through hole 24.

[0043] The positioning mechanism includes an infrared emitting device 16 provided on a support 22, and an infrared receiving device 14 provided on another support 22 and adapted to the infrared emitting device 16; the infrared receiving device 14 has a built-in wireless signal transmitter 25 adapted to the wireless signal receiver 6, and the infrared emitting device 16 and the infrared receiving device 14 are respectively located on two brackets 21.

[0044] Based on Example 3, this Example 4 provides a more preferred structure of the positioning mechanism, specifically: the positioning mechanism includes an infrared emitting device 16 provided on a support 22, and an infrared receiving device 14 provided on another support 22 and adapted to the infrared emitting device 16; the infrared receiving device 14 has a built-in wireless signal transmitter 25 adapted to the wireless signal receiver 6, and the infrared emitting device 16 and the infrared receiving device 14 are respectively located on two brackets 21.

[0045] The two ends of the sample baffle 13 are respectively passed through a connecting rod 23 through corresponding through holes 24, and can slide freely along the length direction of the connecting rod 23. During the sampling process, when the steel bar raw material passes through the blade of the steel bar cutting machine and reaches the upper part of the arc-shaped support plate, the end of the steel bar will push the sample baffle on the arc-shaped support plate to slide along the length direction of the connecting rod 23. The infrared emitting device 16 emits an infrared light beam 15 in real time to illuminate the infrared receiving device 14. The infrared light beam 15 emitted by the infrared emitting device 16 is perpendicular to the length direction of the arc-shaped support plate 4, and the length of the scale corresponding to the infrared light beam 15 on the arc-shaped support plate 4 is the sampling length of the sampling steel bar 18. When the sample baffle 13 is pushed down between the infrared emitting device 16 and the infrared receiving device 14 by the sampling steel bar, it can just block the infrared light beam 15. At this time, the infrared receiving device 14 cannot receive the irradiation of the infrared light beam, so it transmits a wireless signal to the wireless signal receiver 6 built into the wireless control switch 2 through the wireless signal transmitter 25. When the wireless control switch 2 receives the signal transmitted by the wireless signal transmitter 25 through the wireless signal receiver 6, it controls the steel bar cutting machine 1 to cut the sampling steel bar 18.

[0050] The sample baffle 13 can slide freely along the length direction of the two connecting rods 23 , and the sliding direction of the sample baffle 13 is consistent with the length direction of the arc-shaped supporting plate 4 .

[0051] Based on Example 3, this Example 5 provides a more preferred structure for the sample baffle 13, specifically: the sample baffle 13 can slide freely along the length direction of the two connecting rods 23, and the sliding direction of the sample baffle 13 is consistent with the length direction of the arc-shaped support plate 4. The two ends of the sample baffle 13 are respectively penetrated on a connecting rod 23 through corresponding through holes 24, and can slide freely along the length direction of the connecting rod 23. During the sampling process, when the steel bar raw material passes through the blade of the steel bar cutting machine and reaches the upper part of the arc-shaped support plate, the end of the steel bar will push the sample baffle located on the arc-shaped support plate to slide along the length direction of the connecting rod 23. When the positioning mechanism locates the sampling steel bar 18 to the sampling length position through the sample baffle 13, it transmits the information to the wireless control switch 2 through a wireless signal. When the wireless control switch 2 receives the information, it controls the steel bar cutting machine 1 to cut the sampling steel bar 18, and a sampling steel bar with a sampling length that meets the sampling requirements can be obtained.

The infrared emitting device 16 emits an infrared light beam 15 in real time to illuminate the infrared receiving device 14. The infrared light beam 15 emitted by the infrared emitting device 16 is perpendicular to the length direction of the arc-shaped support plate 4, and the length of the scale corresponding to the infrared light beam 15 on the arc-shaped support plate 4 is the sampling length of the sampling steel bar 18. When the sample baffle 13 is pushed down between the infrared emitting device 16 and the infrared receiving device 14 by the sampling steel bar, it can just block the infrared light beam 15. At this time, the infrared receiving device 14 cannot receive the irradiation of the infrared light beam, so it transmits a wireless signal to the wireless signal receiver 6 built into the wireless control switch 2 through the wireless signal transmitter 25.

[0075] Example 10.

[0076] like Figures 1-6 As shown, the present invention provides a fully automatic rapid sampling device for steel bar raw materials at a construction site, comprising a steel bar cutter 1 with a steel bar cutter blade 3 and a wireless control switch 2, wherein the wireless control switch 2 has a built-in wireless signal receiver 6. The device also includes a plurality of height-adjustable brackets 11 arranged side by side, an arc-shaped support plate 4 disposed on the height-adjustable brackets 11 with its head positioned directly below the steel bar cutter blade 3, and an automatic sample alignment device disposed on two adjacent height-adjustable brackets 11, located at the rear ends of the arc-shaped support plates 4, and wirelessly connected to the wireless signal receiver 6 on the wireless control switch 2. The arc-shaped support plates 4 are provided with scales 19 along their lengths.

[0077] The height-adjustable bracket 11 includes a pair of rectangular outer tubes 10, a pair of rectangular inner tubes 7, and a supporting cross bar 5 for supporting the arc-shaped support plate 4; a pair of rectangular inner tubes 7 are respectively welded to the two ends of the supporting cross bar 5, and a pair of rectangular inner tubes 7 are respectively inserted into a rectangular outer tube 10, and a fastening mechanism is provided between the rectangular inner tube 7 and the rectangular outer tube 10.

[0078] A rectangular base 12 is welded to the bottom of the rectangular outer tube 10 .

[0079] This embodiment 10, based on the structure of embodiment 8, provides a more preferred structure for the rectangular outer tube 10. Specifically, a rectangular base 12 is welded to the bottom of the rectangular outer tube 10. Rectangular base 12 is provided with bolt holes and is secured to the ground using bolts that fit into the holes. This effectively ensures the overall stability of the height-adjustable bracket 11, thereby ensuring that rebar sampling can proceed normally and stably, without compromising sampling accuracy.

[0080] The present invention can effectively enhance the adaptability of various steel bar cutting machines at the construction site by adopting an adjustable rectangular support, making on-site steel bar sampling more convenient.

[0081] The invention can effectively improve the accuracy of steel bar sampling by using the arc-shaped supporting plate with scale, and ensure the sampling quality of the test piece.

[0082] The wireless control switch, wireless signal receiver, wireless signal transmitter, infrared receiving device, infrared beam and infrared transmitting device of the present invention form a wireless control device for a steel bar cutting machine, which can effectively reduce the sampling and detection cycle and waste of human resources, improve the efficiency and automation level of steel bar sampling, and meet the safety and quality requirements of on-site construction.

[0083] The present invention enables the sampling of steel bar raw materials at the construction site to be carried out quickly and cyclically through the graduated arc-shaped supporting plate, sample baffle, reset spring, support and connecting rod, making the sampling of steel bar raw materials at the construction site more convenient and economical.

[0084] 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.

[0085] The present invention tailors a curved steel plate with a scale as a steel bar support plate according to the sampling length of the steel bar raw material, and provides a telescopically adjustable height-adjustable bracket at the lower part of the curved support plate. Since the height of the steel bar cutting machine blade is different on the construction site, the height-adjustable bracket can be adjusted in real time according to the position of the steel bar cutting machine blade. The sampling length of the steel bar raw material is fixed, and an infrared emitting device and a receiving device are installed on both sides of the scale position on the curved support plate that meets the standard sampling length. The receiving device has a built-in wireless signal transmitter. When the steel bar raw material passes through the steel bar cutting machine blade and reaches the upper part of the curved support plate, the end of the steel bar will push the sample baffle located on the curved support plate. The compressed return spring moves forward, and when the steel bar pushes the sample baffle to move to the scale position of the standard sampling length, the sample baffle will block the infrared beam emitted by the infrared ray. At this time, the infrared receiving device cannot receive the infrared light, and the built-in wireless signal transmitter of the infrared receiving device will send a signal to the built-in wireless signal receiver of the wireless control switch on the steel bar cutting machine. After receiving the signal through the wireless signal receiver, the wireless control switch controls the steel bar cutting machine to cut the steel bar. The cut steel bar raw material is the sampling specimen. After the sampling specimen is removed, the return spring will push the sample baffle back to its original position, thereby achieving the purpose of cyclic, reciprocating and automated sampling. During the entire sampling process, the control of the steel bar raw material specimen length and the steel bar cutting machine does not require manual assistance. Therefore, the above-mentioned fully automatic rapid sampling device can quickly, accurately and automatically solve the problem of steel bar raw material sampling at the construction site.

[0086] The steel bar cutting machine 1, steel bar cutting machine blade 3, wireless control switch 2, wireless signal receiver 6, wireless signal transmitter 25, infrared emitting device 16, and infrared receiving device 14 used in the present invention are all existing known products and can be directly purchased and used on the market. The structure, circuit, control principle, etc. of the above products are all existing known technologies.
