Description

Technical Field

[0001] The present application belongs to the technical field of construction engineering, and specifically relates to a hoist for construction engineering. Background Art

[0002] Construction engineering hoists, also known as material hoists, lifting towers or construction elevators, are important mechanical equipment used on construction sites to lift construction materials, personnel, tools, etc. This type of equipment is particularly important in the construction process of high-rise buildings, and can significantly improve work efficiency and reduce labor costs. Hoists can be divided into many types according to different usage scenarios, load capacity and height requirements, including tower cranes, construction elevators, material hoists, etc.

[0003] For example, the utility model patent with announcement number CN219860397U discloses a hoist for construction engineering, including a lifting mechanism and a dumping mechanism, and the dumping mechanism is installed on the lifting mechanism; the lifting mechanism includes a base, a side plate, a slide groove, a bracket, a first motor, a screw rod, a lifting block and a hopper, and the side plate is fixedly connected to the base. The utility model overcomes the shortcomings of the prior art. The fixed plate is used to install the second motor, and the second motor is installed on the side of the fixed plate away from the roller shaft. The output shaft of the second motor is fixedly connected to one end of the roller shaft, and the second motor is used to drive the roller shaft to rotate. The rotation of the roller shaft will drive the tightening or loosening of the rope thereon, wherein the rope passes through the through hole, and successively bypasses the first roller and the second roller, and is fixed on the lifting block. When the roller shaft is tightened or loosened, the hopper will produce an inclination angle with the rotation point as the axis under the action of gravity, so as to achieve the purpose of automatic dumping, which is very convenient.

[0004] However, in actual use, it was found that the device can achieve the tilting function of the hopper through the multiple sets of roller systems, which improves the convenience of material discharge;

[0005] However, when the hopper of the device is adjusted to a specific height and tilted, the support structure for carrying the internal material usually needs to extend forward to the bottom of the hopper to ensure smooth discharge of the material. However, this brings certain safety hazards in actual applications. Especially when operating outside a building, the outward extension of the support structure may not only pose a safety threat to the surrounding environment, but also there is a risk of overturning when the support structure is overloaded. For this purpose, a hoist for construction projects is provided. Utility Model Content

[0034] The implementation principle of the embodiment of the hoist for construction engineering of the present application is as follows: when operating the device, first, the operator moves it to the required position for the operation, then puts the material to be lifted into the hopper 8, and then starts the universal motor 23 in the driving adjustment mechanism 7, and the motor 23 drives the gear 24 to rotate. Since the gear 1 22 is meshed with the gear 2 24, the rotation of the gear 2 24 indirectly causes the steel wire rope 20 on the drum 19 to be wound up, so that the mounting frame 6 and the hopper 8 can be adjusted in height until they reach a suitable height;

[0035] At this time, in order to discharge the material inside the hopper 8, the operator starts the electric push rod 16, which pushes the connecting plate 12, the hydraulic telescopic cylinder 13, the T-block 10 and the hopper 8 to move forward. When the hopper 8 moves forward to the top of the supporting structure for carrying the material, the operator starts the hydraulic telescopic cylinder 13 again, and the movement of the hydraulic telescopic cylinder 13 drives the adjustment plate 2 14 to move upward. Since the hopper 8 and the adjustment plate 2 14 and the adjustment plate 1 11 are in a hinged state, the lifting of the adjustment plate 2 14 causes one end of the hopper 8 to tilt forward, so that the material inside the hopper 8 can be smoothly discharged through the front discharge port without extending the bearing structure forward to the bottom of the hopper 8, thereby improving the convenience and safety of material discharge;

[0036] After the material is discharged, the operator controls the hydraulic telescopic cylinder 13 and the electric push rod 16 to gradually reset the hopper 8 to the initial state to prepare for the next round of operation. The device has a reasonable structural design, simple and convenient operation, and realizes efficient material lifting and discharge.
