Description

Technical Field

[0001] The utility model relates to the field of building construction material hoists, in particular to a building construction material hoist with a protective function. Background Art

[0002] In the field of modern construction, with the acceleration of urbanization, high-rise buildings are springing up like mushrooms after rain. Material hoists, as key equipment for vertical transportation of building materials during building construction, play an indispensable role. However, existing building construction material hoists have exposed many safety hazards and technical defects in actual application, making it difficult to meet the needs of the increasingly complex construction environment.

[0003] Traditional material hoists usually focus on realizing the vertical lifting function of materials, and have insufficient ability to deal with emergencies during transportation, especially during the rising stage of the loading frame. Due to the complex and changeable construction site environment and many uncertain factors, the loading frame often faces the risk of getting stuck. In addition, conventional hoists lack a buffer mechanism for the upward pulling force, and the powerful lifting power continues to act, causing the loading frame to bear huge impact force. This impact force can easily cause the loading frame structure to deform, the connectors to loosen or even break, which not only damages the loading frame itself, causing materials to scatter and affecting the construction progress, but also may cause the scattered materials to fall from high altitude, posing a serious safety threat to the construction personnel and equipment below, and causing major safety accidents. Therefore, it is necessary to design a building construction material hoist with protective function to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a building construction material hoist with a protective function to solve the problems raised by the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a building construction material hoist with a protective function, comprising a base, a U-shaped frame fixedly mounted on the top of the base, a slide groove being provided on both sides of the inner cavity of the U-shaped frame, a slider being slidably connected inside the slide groove, a material holding frame being fixedly mounted between the two sliders, and a cover plate being rotatably connected between the two sides of the inner cavity of the material holding frame via a bearing member;

[0006] The top of the material holding frame is fixedly mounted with a motor, and the output shaft of the motor is fixedly mounted with a rotating rod through a coupling, and a reel is fixedly mounted on the surface of the rotating rod, and a pull rope is fixedly mounted on the top of the reel, and one end of the pull rope is fixedly connected to the top of the material holding frame, and the top of the U-shaped frame is rotatably connected to the limit shaft through a bracket, and one side of the pull rope is tightly attached to the surface of the limit shaft; a sleeve is fixedly mounted on both sides of the material holding frame, a spring is welded at the bottom of the inner cavity of the sleeve, and a sliding rod is welded at the top of the spring, and a first protective plate is fixedly mounted on the top of the sliding rod, and the top of the first protective plate is rotatably connected to the second protective plate through a bearing member, and a trigger button used in conjunction with the motor is fixedly mounted on the left side of the material holding frame, and a pressing rod used in conjunction with the trigger button is fixedly mounted on the bottom of the first protective plate on the left.

[0007] Preferably, sockets are fixedly mounted on both sides of the cover plate surface, and an insertion rod is fixedly mounted on the bottom of the second protective plate.

[0008] Preferably, the bottom end of the insertion rod passes through the insertion sleeve and extends to the outside of the insertion sleeve.

[0009] Preferably, limit bars are fixedly installed on both sides of the bottom of the inner cavity of the material holding frame.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The building construction material hoist with protective function is equipped with a first protective plate and a second protective plate, so that the first protective plate and the second protective plate first contact the obstacle during the lifting process of the material holding frame. After the first protective plate and the second protective plate contact the obstacle, they can drive the sliding rod to descend. The descending sliding rod compresses the spring to achieve the effect of buffering the tensile force. At the same time, the descent of the first protective plate drives the pressing rod to descend. After the pressing rod is descended, the trigger button can be pressed. When the trigger button is pressed, the motor can stop working, thereby achieving the effect of protecting the material holding frame.

[0012] 2. This building construction material hoist with protective function can pull the second protective plate upwards. After the second protective plate rises to the outside of the sleeve, the two second protective plates can be flipped to both sides respectively. At the same time, after the insertion rod moves to the outside of the sleeve, the cover plate can be flipped forward, thereby achieving the effect of facilitating the removal of materials in the material frame.
