[0027] In use of the embodiment, in order to solve the technical problem that the cantilever unloading platform in the prior art has a fixed length, so that the space for materials is limited, and the unloading platform is difficult to effectively meet the use requirement for some long or large materials, and greatly affects the actual use effect of the unloading platform, the embodiment provides a telescopic cantilever unloading platform. The platform comprises a steel beam frame 1, a support table 2 movably arranged on the steel beam frame 1 along the length direction of the steel beam frame 1, a first telescopic plate 5 and a second telescopic plate 6 movably arranged on the lower surface of the support table 2 along the length direction of the support table 2 and moving towards or away from each other. Specifically, when the length of the support table 2 needs to be adjusted to meet different use requirements, the bidirectional screw rod 13 is rotated, the bidirectional screw rod 13 drives the fixed block 11 threadedly connected with the two ends of the bidirectional screw rod 13 to move towards or away from each other along the length direction of the bidirectional screw rod 13, the fixed block 11 drives the push-pull arm 12 hingedly connected with the fixed block 11 to rotate in the process of moving, and the same group of push-pull arms 12 drives the first telescopic plate 5 and the second telescopic plate 6 to move towards or away from each other in the process of rotating, so as to increase or shorten the length of the support table 2 and meet different use requirements. Therefore, the telescopic length of the support table 2 can be adjusted, and the length of the cantilever part can be flexibly adjusted under the condition that the anchoring length in the structure meets the requirements, so that the construction requirement is greatly met.

[0028] In the embodiment, the moving mode of the support table 2 on the steel beam frame 1 is that the slide rail 3 is welded on the steel beam frame 1 along the length direction of the steel beam frame 1, and the slide strip 4 matched with the slide rail 3 is welded at the part of the bottom of the support table 2 in contact with the slide rail 3, so as to ensure that the slide strip 4 of the support table 2 moves on the slide rail 3 of the steel beam frame 1, reduce the friction resistance in the moving process of the support table 2, thereby reducing the power for driving the support table 2 to move and saving labor. At the same time, the cooperation of the slide rail 3 and the slide strip 4 can also ensure that the support table 2 moves stably along a straight line.

[0029] In the embodiment, in order to enhance the stability of the overall structure, the triangular reinforcing frame 19 is fixedly connected to the bottom of one end of the steel beam frame 1. The two corners of the bottom side of the reinforcing frame 19 are respectively welded with the lower surface of the steel beam frame 1, so as to form a triangular structure between the reinforcing frame 19 and the steel beam frame 1. A plurality of support cross bars can be welded between the reinforcing frames 19, so as to increase the stability of the reinforcing frame 19 and further increase the stability of the overall structure.

[0030] The other end side wall of the steel beam frame 1 is fixedly connected with a plurality of support seats, the plurality of support seats are symmetrically welded on the two side walls of the steel beam frame 1, a support 20 is welded on each support seat, a mounting seat 21 is fixedly connected to the top end of each support 20, so as to facilitate the reinforcement of the device. The support 20 is welded and fixed with the side wall of the steel beam frame 1 through the support seat, which can increase the contact area between the support 20 and the side wall of the steel beam frame 1, thereby ensuring the stability of the connection between the two, and further increasing the stability of the device.

[0031] In order to ensure that the bidirectional screw rod 13 can stably rotate and drive the fixed block 11 to move, in the embodiment, two fixed seats 10 are fixedly connected to the lower surface of the support table 2 at both ends of the center line, and the bidirectional screw rod 13 is rotatably connected with the fixed seat 10 through a bearing.

[0032] In the embodiment, a driving assembly is connected to one end of the bidirectional screw rod 13 after penetrating the fixed seat 10. The driving assembly can be a driving motor 14, and the output end of the driving motor 14 is connected with the end of the bidirectional screw rod 13. The driving assembly can also be manually driven, and a wrench is detachably connected to one end of the bidirectional screw rod 13 penetrating the fixed seat 10 for rotation.

[0033] In order to ensure the stability of the first telescopic plate 5 and the second telescopic plate 6 during movement, thereby controlling the first telescopic plate 5 and the second telescopic plate 6 to quickly and stably approach or move away from each other, the telescopic length of the support table 2 is adjusted, and the length of the cantilever part can be flexibly adjusted when the structural anchoring length meets the requirements, thereby greatly meeting the construction requirements. In the embodiment, a limiting assembly is arranged between the support table 2 and the first telescopic plate 5 and the second telescopic plate 6. Specifically, a plurality of uniformly distributed limiting grooves 16 are formed in the lower surface of the support table 2 along the width direction, and a plurality of limiting columns 15 are fixedly connected to the upper surfaces of the first telescopic plate 5 and the second telescopic plate 6 and are inserted and matched with the limiting grooves 16. The limiting column 15 is inserted into the limiting groove 16 and can move along the limiting groove 16, and the first telescopic plate 5 and the second telescopic plate 6 can be quickly and stably approached or moved away from each other under the support and limitation of the limiting column 15 and the limiting groove 16.

[0034] In the embodiment, a plurality of rollers can be arranged on the upper surface of the limiting column 15 along the length direction, thereby reducing the friction between the limiting column 15 and the limiting groove 16, reducing the friction loss and the force required to drive the first telescopic plate 5 and the second telescopic plate 6 to move.

[0035] As further description of the above embodiment, the support table 2 is fixedly connected with symmetrically arranged side baffles 8 on both sides, the side baffles 8 are recessed inward to form clamping grooves 18 near one end of the first telescopic plate 5.

[0036] In use of the embodiment, two side baffles 8 are symmetrically welded on both sides of the support table 2, and a front baffle 7 is welded at the end of the first telescopic plate 5, so that the front baffle 7 and the side baffles 8 can form a U-shaped fence to prevent material loss or harm to surrounding personnel caused by falling during material stacking, and improve the stability during material stacking and the safety during use of the device.

[0037] In order to ensure that the U-shaped fence formed between the front baffle 7 and the side baffles 8 can still play a blocking protection role for the material during the movement of the first telescopic plate 5 to adjust the length of the support table 2, in the embodiment, clamping grooves 18 are formed inward at the ends of the side baffles 8, and clamping plates 17 matched with the clamping grooves 18 are connected on both sides of the front baffle 7 and clamped in the clamping grooves 18. When the first telescopic plate 5 moves, the front baffle 7 drives the two clamping plates 17 to slide in the clamping grooves 18 of the side baffles 8, so that the length of the fence structure can be adjusted with the length of the overhanging part, greatly improving the practicability of the device.

[0038] In the embodiment, in order to ensure that the clamping plates 17 can be clamped in the clamping grooves 18, a moving groove is left between the clamping plates 17 and the bottom surface of the first telescopic plate 5.

[0039] In the embodiment, the end of the second telescopic plate 6 is fixedly connected with two symmetrically arranged push rods 9.

[0040] In summary, in the utility model, the rotation of the push-pull arm can simultaneously push and pull the first telescopic plate and the second telescopic plate to move, so that the first telescopic plate and the second telescopic plate can approach or move away from each other, thereby adjusting the telescopic length of the support table, achieving flexible adjustment of the length of the overhanging part under the condition that the anchoring length in the structure meets the requirements, and greatly meeting different construction requirements. Therefore, the utility model effectively overcomes the shortcomings in the prior art and has high industrial utilization value.
