Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a material lifting device for building engineering. Background Technology

[0002] Construction engineering refers to the construction activities of various buildings and structures to meet human needs for residence, production, life and public use. In construction activities, a large amount of materials often need to be transported. In order to reduce the consumption of human resources, a material lifting device for construction engineering is needed.

[0003] Chinese patent provides a material lifting device for construction engineering, publication number CN215101719U, which includes a base, a support, a top plate, a motor, a rope winding drum, guide rods, and a lifting base. The base is connected to the top plate via the support. Guide rods are provided on both sides of the support, and a vertically movable lifting base is mounted on the guide rods. A hopper is placed on the lifting base. The motor is located at the center of the top plate, and the output shaft of the motor is connected to a drive gear. Rope winding drums are provided on both sides of the motor.

[0004] The aforementioned device facilitates material transport and unloading, effectively reducing the labor intensity of workers and improving work efficiency. However, when using this device, the material can only be transported vertically, and the transport path cannot be changed according to the actual use scenario. Furthermore, it is difficult to ensure the stability of the material during transport along different paths. Utility Model Content

[0005] The main objective of this invention is to provide a material lifting device for construction engineering, which can effectively solve the technical problem in the background technology that the material conveying can only be carried out vertically and the conveying path cannot be changed according to the actual use scenario.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A material lifting device for construction engineering includes two base plates. Two connecting plates are fixedly installed on the adjacent surfaces of the two base plates. Two rotating blocks are fixedly installed on the top of the rear connecting plate. A connecting frame is rotatably connected to the adjacent surfaces of the two rotating blocks. A motor is fixedly installed on the left side of the top of the connecting frame. A screw is fixedly installed at the output end of the motor.

[0008] As a further embodiment of this utility model, a sliding rod is fixedly installed on the right side of the top of the connecting frame, and two connecting blocks are provided on the top of the connecting frame, with a material box rotatably connected to the adjacent surfaces of the two connecting blocks.

[0009] As a further embodiment of this utility model, the outer wall of the left connecting block is threadedly connected to the screw, and the outer wall of the right connecting block is slidably connected to the sliding rod.

[0010] As a further embodiment of this utility model, a telescopic frame is slidably connected to the top of the connecting frame, a fixed plate is slidably connected to the top of the telescopic frame, a support plate is rotatably connected to the outer wall of the fixed plate, and the support plate is fixedly connected to the bottom of the material box.

[0011] As a further embodiment of this utility model, the top of the fixing plate is provided with fastening bolts, and the fastening bolts are threadedly connected to the fixing plate and the support plate.

[0012] As a further embodiment of this utility model, the outer walls of the two base plates are provided with grooves, the outer walls of the grooves are provided with support rods, and the outer walls of the support rods are rotatably connected to two connecting strips, and the connecting strips are rotatably connected to the outer walls of the connecting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This material lifting device for construction projects can drive a screw to rotate through the output end of a motor. When the screw rotates, the connecting block on the left side can move up and down, and the connecting block on the right side can slide up and down through a sliding rod, thereby moving the material box up and down. During the movement of the material box, the telescopic frame will also extend and retract synchronously to ensure the stability of the material box during transportation. The support plate can be rotated through the fixed plate, and after the bottom of the material box is parallel to the ground, the fastening bolts can be tightened to fix the fixed plate and the support plate at a certain angle, so that the material box can remain parallel to the ground in both vertical and inclined transportation, and avoid tipping over.

[0015] 2) This material lifting device for construction projects can make the connecting frame no longer perpendicular to the ground by placing the support rods into different grooves, thereby changing the transportation direction of the material box from vertical to oblique upward. It can adapt to different working environments. When vertical transportation is difficult, oblique upward transportation can improve the material transportation efficiency.
