[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not 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 efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 In this embodiment, a steel bar transportation device with good limiting performance includes a trolley 1 and a placing plate 2. A limiting mechanism 3 and an auxiliary mechanism 5 are set on the top of the placing plate 2, and an unloading mechanism 4 is set between the trolley 1 and the placing plate 2.

[0028] The limiting mechanism 3 includes a motor 301, and the motor 301 is fixedly installed on the front side wall of the placing plate 2. A bidirectional threaded rod 1 302 located inside the placing plate 2 is fixedly installed at the output shaft of the motor 301, and a bidirectional threaded rod 2 303 is rotatably installed inside the placing plate 2. A transmission assembly 304 is arranged between the bidirectional threaded rod 1 302 and the bidirectional threaded rod 2 303. The outer surfaces of the bidirectional threaded rod 1 302 and the bidirectional threaded rod 2 303 are threadedly connected with two moving blocks 305, and the tops of the four moving blocks 305 are fixedly installed with connecting rods 306, and the tops of the four connecting rods 306 are fixedly installed with limiting plates 307.

[0029] The transmission assembly 304 includes a pulley 1, a pulley 1 is fixedly installed on the bidirectional threaded rod 1 302, a pulley 2 is fixedly installed on the bidirectional threaded rod 2 303, and a transmission belt is installed between the pulley 1 and the pulley 2.

[0030] When the motor 301 drives the bidirectional threaded rod 1 302 to rotate, it drives the pulley 1 to rotate, the pulley 1 drives the transmission belt to rotate, and the transmission belt drives the pulley 2 to rotate, thereby driving the bidirectional threaded rod 2 303 to rotate at the same time.

[0031] Two openings are provided on the top of the placement plate 2 , and the top ends of the four connecting rods 306 pass through the corresponding openings and extend to the bottoms of the corresponding limiting pieces 307 . Both openings are adapted to the connecting rods 306 .

[0032] By setting the opening, when the bidirectional threaded rod 1 302 and the bidirectional threaded rod 2 303 rotate, the two moving blocks 305 on their outer surfaces can be driven to move relative to each other, thereby driving the two limiting pieces 307 to move relative to each other through the connecting rod 306 to fix the steel bars.

[0033] By providing four limiting pieces 307 , with two of each piece forming a group, both sides of the steel bar can be clamped simultaneously, thereby improving the fixing effect.

[0034] The auxiliary mechanism 5 includes a vertical plate 501, and the tops of the two limit plates 307 are both connected with vertical plates 501. A horizontal plate 1 502 is fixedly installed on the top of one of the vertical plates 501, and a horizontal plate 2 503 is fixedly installed on the top of the other vertical plate 501. A plug-in cavity 504 is provided on the side of the horizontal plate 2 503 close to the horizontal plate 1 502, and the plug-in cavity 504 is adapted to the horizontal plate 1 502. The horizontal plates 1 502 can move back and forth in the plug-in cavity 504, and a group of positioning holes 505 are provided at equal distances on the left and right sides of the vertical plate 501.

[0035] The tops of the four limiting plates 307 are each provided with a receiving cavity 6 that is compatible with the vertical plate 501, and the left and right sides of the two limiting plates 307 are each provided with a screw hole 7, and the four screw holes 7 are all threadedly connected with nuts 8, and the two groups of positioning holes 505 are both compatible with the nuts 8.

[0036] Every two vertical plates 501 can be inserted into the corresponding limiting plates 307 through the accommodating cavity 6, and the two horizontal plates 502 can be inserted into the corresponding horizontal plates 503 through the insertion cavity 504, so as to realize the installation of the auxiliary mechanism 5 between the two limiting plates 307, and the auxiliary mechanism 5 is fixed between the two limiting plates 307 by inserting the nut 8 into the positioning hole 505.

[0037] In addition, there are multiple positioning holes 505 that are evenly distributed. The positioning holes 505 are compatible with the nuts 8, which can achieve the adjustment and fixation of the auxiliary mechanism 5 at different heights. The top of the steel bar is fixed by the two vertical plates 501 contacting the two ends of the top of the steel bar, thereby further improving the stability during fixation.

[0038] The unloading mechanism 4 includes a hydraulic cylinder 401, which is fixedly installed on the top of the cart 1. The driving end of the hydraulic cylinder 401 is hinged with a slider 402. The bottom of the placement plate 2 is provided with a slide groove 403 that is compatible with the slider 402. A support frame 404 is provided between the cart 1 and the placement plate 2.

[0039] There are two support frames 404 , and the placement plate 2 is hinged between the two support frames 404 . The bottoms of the two placement plates 2 are fixedly mounted to the top of the cart 1 .

[0040] Through the sliding cooperation between the slider 402 and the slide groove 403, when the hydraulic cylinder 401 is driven, the placement plate 2 can be turned over between the two support frames 404, thereby realizing automatic unloading.

[0041] A baffle is fixedly installed on the top left end of the placement plate 2 to prevent the steel bars from sliding off the left side of the placement plate 2 during unloading.

[0042] A power supply is fixedly installed on the top of the cart 1 , and the power supply is electrically connected to the motor 301 and the hydraulic cylinder 401 .

[0043] During implementation, follow these steps:

[0044] 1) By starting the motor 301, the motor 301 drives the bidirectional threaded rod 1 302 to rotate, and under the action of the transmission assembly 304, the bidirectional threaded rod 2 303 is also driven to rotate;

[0045] 2) Then, when the bidirectional threaded rod 1 302 and the bidirectional threaded rod 2 303 rotate, the two movable blocks 305 on their outer surfaces move in opposite directions. The two movable blocks 305 respectively drive the two limit plates 307 connected thereto to move relative to each other, thereby clamping and fixing the two sides of the steel bar between the two limit plates 307;

[0046] 3) According to the distance between the two limiting pieces 307, the horizontal plate 1 502 is inserted into the horizontal plate 2 503 through the insertion cavity 504, and the distance between the two vertical plates 501 is adjusted. Thereafter, the depth of the two vertical plates 501 inserted into the limiting pieces 307 is adjusted according to the height at which the steel bars need to be fixed. After adjusting to the appropriate position, the screw holes 7 are aligned with the corresponding positioning holes 505, and the position of the auxiliary mechanism 5 is fixed by inserting the nuts 8 into the positioning holes 505, so that the horizontal plate 1 502 and the horizontal plate 2 503 are pressed against the top of the steel bars to fix the top ends of the steel bars;

[0047] 4) Finally, the device is transported to the unloading site. The hydraulic cylinder 401 is extended to drive the slider 402 to slide to the left in the slide 403, so that the placement plate 2 rotates on the two support frames 404 to an inclined state. The limiting plate 307 is loosened and the auxiliary mechanism 5 is removed to release the limit on the steel bars, and the steel bars automatically slide to the right from the placement plate 2.

[0048] To sum up, this steel bar transportation device with good limiting performance can clamp and fix the left and right ends of the steel bar under the action of the limiting mechanism 3, so that the steel bar is stably limited on the top of the placement plate 2; through a motor 301, each two limiting plates 307 can be driven to move relative to each other, thereby achieving stable clamping of the two ends of the steel bar, thereby improving stability during transportation.

[0049] Moreover, by setting up the auxiliary mechanism 5, the top of the steel bars stacked to different heights can be fixed. Combined with the limiting mechanism 3 to fix the two sides of the steel bars, the two sides and the top of the steel bars can be fixed at the same time, further enhancing the fixing effect of the steel bars. Moreover, the auxiliary mechanism 5 can be removed and will not hinder the steel bars from being placed on the placement plate 2.

[0050] Furthermore, by setting up an unloading mechanism 4, the inclination angle of the placement plate 2 can be adjusted; when the inclination of the placement plate 2 changes, the steel bars on it can automatically slide down along the inclined surface, realizing an automatic unloading function without human intervention, which greatly simplifies the unloading process and improves operational efficiency.
