Description

Technical Field

[0001] The utility model relates to the technical field of material lifting, in particular to a material lifting machine for construction engineering. Background Art

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. "Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's production, living, learning, and public activities. During the construction process of construction engineering, it is often necessary to use hoists to transport materials, so as to conveniently lift the materials needed for construction, such as steel bars, cement, and plates.

[0003] Prior art CN202022421883.7, a construction material hoist, drives a threaded rod to rotate through the rotation of a motor. Since the threaded rod is threadedly connected to the lifting platform, the lifting platform will move up or down on the surface of the threaded rod, thereby achieving the effect of lifting the material. By starting the hydraulic rod, the pushing platform can move along the slide groove to one side of the base through the extension of the hydraulic rod, so that construction workers can directly remove materials from the lifting platform. This design can prevent construction workers from accidentally falling from a height when leaning out to take objects.

[0004] However, when the hoist is used to lift materials that are stacked too high, the materials piled on the top may easily fall when the hoist reaches a specified height and stops; therefore, it does not meet existing needs. In this regard, we propose a construction material hoist. Utility Model Content

[0005] The utility model aims to provide a construction material elevator to solve the problem that when the elevator proposed in the above background technology lifts materials stacked too high, the materials piled on the top are easily caused to fall when the elevator stops at a specified height.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a construction material hoist, comprising a base, a support frame is fixedly provided on the upper end of the base, a threaded rod is connected to one side of the bottom end of the support frame through a motor drive, a sliding rod is fixedly provided on one side of the threaded rod, a lifting platform is connected between the outer surfaces of the threaded rod and the sliding rod, baffles are fixedly connected to both sides of the upper end of the lifting platform, grooves are provided at the upper ends of the baffles on both sides, and an extension plate is slidably connected inside the groove and extends through and to the outer side of the upper end of the baffle.

[0007] Preferably, one end of the lifting platform close to the support frame is threadedly connected to the outer surface of the threaded rod, and the other end of the lifting platform close to the support frame is slidably connected to the outer surface of the sliding rod.

[0008] Preferably, the bottom end of the groove is rotatably connected to a bidirectional threaded rod via a rotating shaft, and both sides of the outer surface of the bidirectional threaded rod are threadedly connected to threaded blocks.

[0009] Preferably, both sides of the bottom end of the extension plate near the middle are fixedly connected with hinge seats, and a connecting rod is hinged between the outer surface of the threaded block and the hinge seat.

[0010] Preferably, one end of the bidirectional threaded rod extends through and to the outside of the baffle and is fixedly connected to a turning handle, a movable groove is provided inside one end of the turning handle, and a spring pin is movably connected inside the movable groove and extends through and to the outside of the turning handle, and a plurality of limiting grooves are provided on the outer surface of the baffle close to the turning handle, and one end of the spring pin extends through and to the outside of the turning handle and is plugged into the corresponding limiting groove.

[0011] Preferably, the support frame is located away from one side of the lifting platform, and a counterweight is provided at the upper end of the base.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model places materials on the lifting platform, and then pulls the spring pin according to the height of the material accumulation to make it disengage from the clamping connection with the limit groove, and then rotates the turning handle to drive the two-way threaded rod to rotate. When the two-way threaded rod rotates, the threads drive the threaded blocks on both sides to approach each other, and then the threaded blocks are hinged with the extension plate through the connecting rod, so that the extension plate is pushed to move up along the groove and extend out of the outside of the baffle, so that the baffle cooperates with the extension plate to increase the shielding height, and by releasing the pulling on the spring pin, the spring pin is clamped with the corresponding limit groove, thereby limiting the rotation of the two-way threaded rod and limiting the position of the extension plate.

By starting the motor 4 to drive the threaded rod 5 to rotate, the lifting platform 7 can be raised or lowered along the sliding rod 6.

[0022] The bottom end of the groove 801 is rotatably connected to a bidirectional threaded rod 11 through a rotating shaft, and thread blocks 12 are threadedly connected to both sides of the outer surface of the bidirectional threaded rod 11.

[0023] By placing the material on the lifting platform 7, and then pulling the spring pin 15 according to the height of the material accumulation, it is disengaged from the clamping connection with the limit groove 802, and then the handle 10 is rotated to drive the bidirectional threaded rod 11 to rotate.
