Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to a material hoist for construction sites. Background Technology

[0002] Construction engineering is a special accounting category for building and installation companies. It refers to the activities of building new, expanding, or renovating construction projects according to the requirements of building engineering design documents. Material hoists are often needed when transporting materials up and down.

[0003] The disassembly process for the soundproof covers of most existing construction site material hoists is complicated. When performing regular wear inspections, lubrication maintenance, or fault repairs on the hoisting mechanism, tools such as wrenches or welding machines are required. Maintenance personnel should not be allowed to quickly disassemble the soundproof covers in emergency situations and directly contact faulty components, which increases the time for troubleshooting and repair and increases the risk of safety accidents caused by malfunctions.

[0004] Therefore, those skilled in the art have provided a material hoist for construction sites to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a material hoist for construction sites. This equipment can block the noise generated by the hoisting mechanism from spreading to the outside, thereby reducing noise and protecting its internal equipment from external damage. It also allows maintenance personnel to quickly disassemble the soundproof cover in emergency situations, shortening the troubleshooting and repair time and reducing the risk of safety accidents caused by malfunctions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A material hoist for construction sites includes a base, with columns fixedly installed at the four corners of the upper end of the base, and a top plate fixedly installed between the four columns and located on top of it; The top plate has placement grooves on both sides of the upper end, and installation grooves on one side of each of the two placement grooves. Guide grooves are provided at the upper and lower ends of each of the two installation grooves. Sliding sleeves are slidably arranged in the four guide grooves. Each pair of sliding sleeves is fixedly connected to a locking block located in the installation groove. A threaded hole is provided in the middle of one side of each of the two locking blocks. A screw is rotatably arranged in the two threaded holes. A connecting block is placed in each of the two placement grooves. A through hole is provided on one side of each of the two connecting blocks and a locking block is engaged inside. A soundproof cover is fixedly connected between the two connecting blocks and located on its upper end.

[0007] Furthermore, a sliding groove is provided on one side of each of the four columns, a guide rod is fixedly installed inside the four sliding grooves, a slider is sleeved on the outer wall of each of the four guide rods, a lifting plate is fixedly connected between the four sliders, and a lifting ring is fixedly installed in the middle of both sides of the upper end of the lifting plate; With the above technical solution, when the winch roller rotates, the steel rope can be wound up, causing the lifting plate to move. Under the combined action of the chute, guide rod and slider, the stability of the lifting plate during the movement is ensured.

[0008] Furthermore, a first rotating seat is provided on one side of the middle of the upper part of the lifting plate, and a material hopper is rotatably arranged inside the first rotating seat.
