[0001] This utility model relates to the field of material safety lifting technology, specifically to a building material safety lifting device. Background Technology

[0002] The building material lifting device is a fixed mechanical conveying equipment, mainly suitable for the continuous vertical lifting of powdery, granular and small block materials.

[0003] However, in the operation of existing lifting devices, when the lifting box is on the ground, the ground provides support for the lifting box. When the lifting box is at its highest point, the bottom of the lifting box cannot provide support. Relying solely on the traction force from above is insufficient to ensure the stability of the lifting box, resulting in low safety. Utility Model Content

[0004] The purpose of this invention is to provide a safe lifting device for building materials, so as to solve the problem of low stability when the lifting box is at a high position as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a building material safety lifting device, comprising:

[0006] A safety hoist, wherein a hydraulic cylinder is installed at the bottom of the hoisting box, and a door assembly is installed at the inlet and outlet ends of the hoisting box;

[0007] A stabilizing component includes a hydraulic cylinder, a connecting rod fixedly mounted on the output end of the hydraulic cylinder, a movable insert plate fixedly connected to the end of the connecting rod away from the hydraulic cylinder, guide blocks inserted inside both sides of the movable insert plate, a fixing plate inserted inside the end of the movable insert plate away from the connecting rod, and mounting blocks fixedly mounted on both sides of the middle position of the fixing plate.

[0008] Preferably, the gate assembly includes a fixing rod, a door frame is connected to the middle outer wall of the fixing rod, a filter screen is fixedly installed inside the door frame, torsion springs are provided on the upper and lower outer peripheries of the fixing rod, and a limit plate abuts against the outer wall of the door frame near the fixing rod.

[0009] Preferably, the hydraulic cylinder is fixedly connected to the lifting box of the safety hoist, and the sliding position of the movable insert plate is provided with a groove corresponding to the size of the guide block.

[0010] Preferably, the movable insert plate has a groove corresponding to the size of the fixed plate, and the mounting block is fixedly connected to the support frame of the safety hoist.

[0011] Preferably, the fixed rod is fixedly connected to the lifting box of the safety hoist, and the door frame is rotatably connected to the fixed rod.

[0012] Preferably, the two ends of the torsion spring are fixedly connected to the door frame and the safety hoist, respectively, and the movable insert plate is slidably connected to the guide block.

[0013] Preferably, the limiting plate is fixedly connected to the lifting box of the safety hoist, and the guide block is fixedly connected to the safety hoist.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The new building material safety lifting device, through the setting of the stabilizing component, when the lifting box of the safety lifting machine is at a high position, before unloading, the hydraulic cylinder is started. The output end of the hydraulic cylinder drives the connecting rod to move, the connecting rod drives the moving insert plate to move, and the moving insert plate is sleeved on the outer wall of the fixed plate. By using the lever principle, a certain supporting force is provided for the lifting box of the safety lifting machine, ensuring the stability of the lifting box and the safety of workers when unloading.

[0016] (2) The new building material safety lifting device has a door frame component. The traditional lifting box does not have a box door. Now, when loading materials, the door frame can be directly pushed into the lifting box of the safety lifting machine to rotate. When the door frame is not pushed, the door frame returns to the initial state under the elastic force of the torsion spring. The door frame is limited by the limit plate and cannot rotate to the outside of the lifting box, which ensures the safety of the material during lifting and avoids the material falling accidentally.

[0026] The stabilizing component 02 includes a hydraulic cylinder 21, which provides power. Activating the hydraulic cylinder 21 can drive the connecting rod 22 to move. The connecting rod 22 is fixedly installed at the output end of the hydraulic cylinder 21. A movable insert plate 23 is fixedly connected to the end of the connecting rod 22 away from the hydraulic cylinder 21. The movable insert plate 23 is fitted onto the outer wall of the fixed plate 25. Using the lever principle, a certain supporting force is provided for the lifting box of the safety hoist 01.

Mounting blocks 26 are fixedly installed on both sides of the middle position of the fixed plate 25.

[0027] Furthermore, the door frame assembly 03 includes a fixing rod 31, with a door frame 32 connected to the middle outer wall of the fixing rod 31. A filter screen 33 is fixedly installed inside the door frame 32. Torsion springs 34 are installed on the outer periphery of the upper and lower ends of the fixing rod 31. The torsion springs 34 provide elastic force. Under the elastic force of the torsion springs 34, the door frame 32 returns to its initial state. The outer wall of the door frame 32 near the fixing rod 31 abuts against a limit plate 35. The limit plate 35 plays a limiting role and can prevent the door frame 32 from rotating on the outside of the lifting box.

[0028] Furthermore, the hydraulic cylinder 21 is fixedly connected to the lifting box of the safety hoist 01 to ensure the stability of the hydraulic cylinder 21. The hydraulic cylinder 21 provides power, and starting the hydraulic cylinder 21 can drive the connecting rod 22 to move.

[0029] Furthermore, the movable insert plate 23 has a groove corresponding to the size of the fixed plate 25. The movable insert plate 23 is fitted onto the outer wall of the fixed plate 25. Using the lever principle, it provides a certain support force for the lifting box of the safety hoist 01. The mounting block 26 is fixedly connected to the support frame of the safety hoist 01 to ensure the firmness of the mounting block 26.

[0030] Furthermore, the fixed rod 31 is fixedly connected to the lifting box of the safety hoist 01 to ensure the stability of the fixed rod 31, and the door frame 32 is rotatably connected to the fixed rod 31.

[0031] Furthermore, the two ends of the torsion spring 34 are fixedly connected to the door frame 32 and the safety hoist 01, respectively. The torsion spring 34 provides elastic force. Under the action of the elastic force of the torsion spring 34, the door frame 32 returns to the initial state. The movable insert plate 23 is slidably connected to the guide block 24. The guide block 24 plays a guiding role for the movable insert plate 23.

[0032] Furthermore, the limiting plate 35 is fixedly connected to the lifting box of the safety hoist 01, and the limiting plate 35 plays a limiting role to prevent the outside of the lifting box of the door frame 32 from rotating. The guide block 24 is fixedly connected to the safety hoist 01 to ensure the firmness of the guide block 24 position.

[0033] Working principle: During use, the door frame 32 is first pushed directly into the lifting box of the safety hoist 01 with the material. After loading, the door frame 32 returns to its initial state under the elastic force of the torsion spring 34. When the lifting box of the safety hoist 01 is at a high position, before unloading, the hydraulic cylinder 21 is activated. The output end of the hydraulic cylinder 21 drives the connecting rod 22 to move, and the connecting rod 22 drives the moving insert plate 23 to move. The moving insert plate 23 is fitted onto the outer wall of the fixed plate 25. The above is the complete working principle of this utility model.
