[0017] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0018] See also Figure 1-Figure 5 A freight elevator for lifting long materials for construction, comprising a support frame 1, a loading plate 101 and a first driving assembly, wherein the loading plate 101 is located inside the support frame 1, the loading plate 101 is U-shaped, and is used to carry the materials to be lifted, a first driving assembly is arranged on the support frame 1, and the first driving assembly is used to drive the loading plate 101 to perform lifting and lowering movements, a conveyor belt 3 is installed on the loading plate 101, and the conveyor belt 3 is used to transport the materials in the left and right directions, a counterweight block 4 is slidably connected to the bottom of the loading plate 101, and is used to adjust the center of gravity of the loading plate 101 according to the transfer of the materials, and a second driving assembly is arranged at the bottom of the loading plate 101, and the second driving assembly is used to drive the counterweight block 4 to move in the left and right directions.

[0019] A mounting plate 601 is fixedly connected to the bottom of the loading plate 101, and a U-shaped clamping rod 602 is symmetrically slidably connected to the mounting plate 601 front and back. A bidirectional electric push rod 603 is installed between the two U-shaped clamping rods 602 at the bottom of the loading plate 101, and the two telescopic rods of the bidirectional electric push rod 603 are respectively connected to the two U-shaped clamping rods 602. A plurality of clamping slots 102 matching the U-shaped clamping rods 602 are opened on the support frame 1. After the loading plate 101 rises to the specified position, the U-shaped clamping rod 602 is driven by the bidirectional electric push rod 603 to move and clamp into the clamping slot 102, so as to realize the locking of the loading plate 101 and improve the stability of the freight elevator.

[0020] The second driving assembly includes a motor 501 and a screw rod 502. The screw rod 502 is rotatably connected to the bottom of the mounting plate 601, and the counterweight block 4 is threadedly connected to the screw rod 502. The motor 501 is installed at the bottom of the carrier plate 101, and one end of the screw rod 502 is drivingly connected to the output shaft of the motor 501. A guide rod 503 is provided at the bottom of the mounting plate 601, and the counterweight block 4 is slidably connected to the guide rod 503.

[0021] The first driving assembly includes a hydraulic cylinder 201, a lifting rod 202, a sprocket 203 and a chain 204. The two hydraulic cylinders 201 are respectively located at the front and rear sides of the support frame 1. The top of the hydraulic cylinder 201 is fixedly connected with the lifting rod 202, and the lifting rod 202 is slidably connected to the support frame 1. The left and right sides of the lifting rod 202 are connected with sprockets 203, and the chains 204 are wound around the sprockets 203. The two ends of the chain 204 are respectively connected to the carrier plate 101 and the bottom plate of the support frame 1. Through the telescopic movement of the hydraulic cylinder 201, the lifting rod 202 is driven to slide up and down along the support frame 1, thereby driving the carrier plate 101 to rise and fall smoothly through the chain 204.

[0022] The left and right ends of the loading plate 101 are rotatably connected with guardrails 701, and the front and rear ends of the upper part of the guardrail 701 are slidably connected with wedge-shaped blocks 702. The wedge-shaped blocks 702 and the guardrail 701 are connected with elastic members 703. The loading plate 101 is provided with a card slot 103 matching the wedge-shaped blocks 702. The wedge-shaped blocks 702 are fixedly connected with a pull block 704 for manually operating the extension and retraction of the wedge-shaped blocks 702 on the guardrail 701. When the guardrail 701 needs to be locked, the guardrail 701 is rotated inwardly, and the wedge-shaped blocks 702 are connected to the loading plate 101. When the guardrail 701 is unlocked, the pulling block 704 on the same guardrail 701 is manually moved in a direction toward each other, so that the two wedge-shaped blocks 702 on the guardrail 701 are contracted at the same time, and the engagement state between the wedge-shaped blocks 702 and the second slot 103 is released, so that the guardrail 701 can be freely rotated.

[0023] A plurality of rollers 8 are rotatably connected to the guardrail 701. When the guardrail 701 is extended outward and the material moves on the guardrail 701, the rollers 8 can reduce the friction between the material and the guardrail 701 by rolling, thereby improving the smoothness of the material transfer.

[0024] Working principle: Initially, the loading plate 101 is located at the bottom of the support frame 1, and the material enters and exits from left to right. The left guardrail 701 opens outward and contacts the ground to facilitate the entry of materials, and the right guardrail 701 remains locked on the right side of the loading plate 101.

[0025] When in use, a part of the material is moved from the left side guardrail 701 to the conveyor belt 3, and then the whole material is conveyed by the conveyor belt 3 until it is completely in the loading plate 101. Then, by rotating the left side guardrail 701 inward, the wedge-shaped block 702 thereon will automatically shrink when it contacts the loading plate 101, and compress the elastic member 703. When the wedge-shaped block 702 rotates with the left side guardrail 701 to face the second card slot 103, the wedge-shaped block 702 is elastically acted upon by the elastic member 703 and is inserted into the second card slot 103, completing the locking of the left side guardrail 701. The carrier 101 is driven to rise to the target position by the first driving assembly. Specifically, the hydraulic cylinder 201 works to make the lifting rod 202 slide upward along the support frame 1, thereby driving the carrier 101 to rise smoothly through the chain 204. When the carrier 101 reaches the target position, the two telescopic rods of the two-way electric push rod 603 are extended to push the two U-shaped clamping rods 602 into the corresponding clamping slots 102 on the support frame 1, thereby locking the carrier 101, improving the stability and reliability of the freight elevator in the subsequent material transfer process, and reducing the burden of the first driving assembly.

[0026] After the carrier 101 reaches the target position, the wedge-shaped block 702 on the right side guardrail 701 is retracted into the guardrail 701 by manually moving the pull block 704, the locking state of the right side guardrail 701 is released, the corresponding elastic member 703 is compressed, and then the right side guardrail 701 is rotated to open until it contacts the target ground to prepare for material unloading. At this time, the wedge-shaped block 702 will return to its original position under the action of the elastic member 703, and then the conveyor belt 3 is started to transport the material from the right side guardrail 701 to the specified position. In this process, the motor 501 drives the screw rod 502 to rotate, and the rotation of the screw rod 502 drives the counterweight block 4 to move along the guide rod 503. The position of the counterweight block 4 is adjusted according to the transfer of the material, thereby ensuring the balance of the center of gravity of the carrier 101 and preventing it from tilting.

[0027] In addition, when the material passes through the guardrail 701 during the transfer process, the roller 8 on the guardrail 701 can reduce the friction between the guardrail 701 and the material, making the material smoother during the transfer process.

[0028] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
