Description

Technical Field

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

[0002] Construction material hoisting equipment is used to lift materials from the ground to the required height or position on a construction site. It plays a vital role on construction sites, effectively reducing labor costs and improving work efficiency, making it an indispensable piece of equipment in modern construction. For example, utility model patent CN218114875U discloses a building material hoist, including a mounting base, casters, and a column. The casters are installed at the bottom of the mounting base, the column is fixedly installed on the upper surface of the mounting base, a support tower wheel is fixedly installed on the top of the column, and a mounting plate is fixedly installed on the right surface of the column. This building material hoist, by placing material on the upper surface of the hoisting plate, when the material compresses the drive plate, the drive plate will compress the bottom of the second side plate, thereby clamping the material on the upper side of the second side plate and limiting the material from the front and rear sides of the hoisting plate. By activating the double-headed hydraulic rod, the clamping arm can be driven, which in turn drives the first side plate, so that the first side plate limits the material from the left and right sides of the hoisting plate, thus fixing the material. However, in the existing technology, when the device reaches the designated position, there is no limiting mechanism, making it difficult to limit the wheels. This can lead to instability when the device is in place. Furthermore, when the device is in use, there is no supporting mechanism, making it difficult to support components such as connecting plates, which can also cause instability during operation. Therefore, improvements are needed. Utility Model Content

[0020] Please see Figures 1-5A building material lifting device includes a floor 1, a hydraulic cylinder 2 fixedly installed at the upper end of the floor 1, a connecting plate 3 fixedly connected to the upper end of the hydraulic cylinder 2, a connecting column 4 fixedly connected to the upper end of the floor 1, the connecting column 4 contacting the connecting plate 3, a sliding block 5 slidably connected inside the connecting column 4, the sliding block 5 being fixedly connected to the connecting plate 3, a connecting rod 6 slidably connected inside the sliding block 5, both ends of the connecting rod 6 being fixedly connected to the connecting column 4, a support mechanism 7 provided on the connecting column 4, wheels 8 provided at the lower end of the floor 1, and a limit mechanism 9 provided on the floor 1.

[0021] Please see Figure 2 , Figure 4 The support mechanism 7 includes a motor 71. The motor 71 is fixedly mounted on the outside of the connecting column 4. The rotating shaft of the motor 71 is rotatably connected to the connecting column 4. A screw 72 is fixedly connected to the rotating shaft of the motor 71. A bearing 73 is fixedly sleeved inside the connecting column 4. The screw 72 is fixedly sleeved inside the inner ring of the bearing 73. By designing the bearing 73, the screw 72 can be supported to rotate. The screw 72 is rotatably connected to the connecting column 4. A threaded block 74 is threadedly connected to the outside of the screw 72. A movable plate 75 contacts the inside of the connecting column 4. The movable plate 75 is fixedly connected to the threaded block 74. The upper end of the movable plate 75... A slider 76 is fixedly connected, and a guide rod 77 is slidably connected inside the slider 76. The two ends of the guide rod 77 are fixedly connected to the connecting column 4. By designing the guide rod 77, the slider 76 can be guided. The connecting column 4 is slidably connected to the slider 76. A limiting tooth 78 is fixedly connected to the outside of the moving plate 75, and a connecting tooth 79 is fixedly connected to the outside of the sliding block 5. By rotating the screw 72 and the threaded block 74, a threaded movement occurs. The movement of the threaded block 74 drives the limiting tooth 78 and other components to move. The limiting tooth 78 moves into the connecting tooth 79, thereby supporting the connecting plate 3 and other components, making the device stable in use.

[0022] Please see Figure 5 The limiting mechanism 9 includes a connecting groove 91. The wheel 8 has a connecting groove 91 inside. A locking block 92 is slidably connected inside the connecting groove 91. A sliding plate 93 is fixedly connected to the end of the locking block 92 away from the connecting groove 91. A connecting block 94 is fixedly connected to the side of the sliding plate 93 away from the locking block 92. A moving ring 95 is fixedly connected to the side of the connecting block 94 away from the sliding plate 93. By designing the moving ring 95, the locking block 92 can be moved. A guide rod 96 is fixedly connected inside the floor 1. The guide rod 96 is slidably connected to the sliding plate 93. A locking groove 97 is opened inside the sliding plate 93. An elastic locking block 98 is locked inside the locking groove 97. The elastic locking block 98 is fixedly connected to the guide rod 96. The sliding plate 93 is slidably connected to the floor 1. By moving the sliding plate 93 towards the wheel 8, the movement of the sliding plate 93 drives the locking block 92 and other components to move. The locking block 92 moves into the connecting groove 91, thereby limiting the wheel 8 and making the device stable in the designated position.

[0023] The specific implementation process of this utility model is as follows: When the device reaches the designated position, the moving ring 95 moves towards the wheel 8.

The movement of the sliding plate 93 drives the slot 97 and the locking block 92 to move. The slot 97 moves and separates from the elastic locking block 98. The locking block 92 moves into the connecting groove 91, thereby making the slot 97 engage with another elastic locking block 98, thereby limiting the wheel 8 and making the device stable in the designated position.

[0024] When the device is in use, the material is placed on the designated position on the connecting plate 3, and then the hydraulic cylinder 2 is activated. The hydraulic cylinder 2 drives the connecting plate 3 to move upward. The upward movement of the connecting plate 3 causes the material and the sliding block 5 to move upward. The upward movement of the sliding block 5 causes the connecting tooth 79 to move upward. After the connecting plate 3 and other components move upward to the designated position, the drive motor 71 is activated. The motor 71 drives the screw 72 to rotate. The rotation of the screw 72 causes threaded movement with the threaded block 74, which in turn causes the threaded block 74 to have relative displacement. The movement of the threaded block 74 causes the moving plate 75 to move. The movement of the moving plate 75 causes the slider 76 and the limiting tooth 78 to move. The limiting tooth 78 moves into the connecting tooth 79, thereby supporting the connecting plate 3 and other components and making the device stable in use.
