Description

A construction material lifting device

Technical Field

The utility model relates to the technical field of material lifting, in particular to a material lifting device for engineering construction.

Background Art

Building construction refers to production activities during the implementation stage of engineering construction. It is the construction process of various types of buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place of construction is called "building construction site" or "construction site", also called construction site. Materials used in construction are generally heavier objects, which are not convenient to carry by hand during construction. Therefore, when building high-rise buildings, material lifting devices are needed to facilitate the lifting of heavy materials to high-rise buildings.

To this end, the China Patent Network has disclosed a material lifting device for construction engineering with application number 201920623230.1. By adopting a spiral lifting structure, the situation where the rope structure is easy to break is avoided, the construction is safer and more reliable, and the protection of workers' personal safety is improved. The upper and lower ends of the spiral rod are rotated and fixed by base one and a rotating seat. First, the material box filled with materials is transported to the side of the lifting block. The fixing buckle is located above the fixed groove, and then the No. 2 motor is started. The No. 2 machine shaft rotates and engages with the No. 2 belt through the No. 2 belt shaft to drive the spiral rod to rotate. When the spiral rod rotates, the lifting seat spirally connected to the spiral rod will be lifted, and then unloading can be stopped on the wall surface by controlling the operation of the two motors, which reduces the difficulty of transportation and saves a lot of labor costs.

Although the above application meets the user's needs to a certain extent, there are still certain defects in the use process. The specific problems are as follows: since the materials are transported through the material box when the materials are lifted, and the material box is lifted by the cooperation between the fixing buckle and the fixing groove, when the material inside the material box is overweight, the fixing buckle is easily damaged, which reduces the safety of the movement of the material box. Based on this, the utility model designs a construction material lifting device to solve the above problems.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-4. The utility model provides a technical solution: a construction material lifting device, including a mobile base 1, a transport lifting assembly 2 is fixedly installed on the top of the mobile base 1, and the transport lifting assembly 2 includes a fixed plate 201, a load-bearing plate 202, a side baffle 203, a mounting frame 205 and a wire rope 207;

A fixed plate 201 for lifting materials is provided at the top of the mobile base 1, and a carrying plate 202 for carrying materials is slidably connected to one side of the fixed plate 201. Side baffles 203 for limiting the position of materials are provided on both sides of the top of the carrying plate 202. Mounting frames 205 are provided on both sides of the fixed plate 201. A steel wire rope 207 for stably connecting the carrying plate 202 is provided on the inner side of the mounting frame 205. The steel wire rope 207 is wound and connected to the outer side of the winding rod 206, so as to synchronously drive the steel wire rope 207 to be wound, thereby ensuring the stability of the movement of the carrying plate 202.

A limit fixing assembly 3 is fixedly installed on the top of the bearing plate 202, and the limit fixing assembly 3 includes a front baffle 301, a limit spring 302 and a positioning plate 303;

One side of the support plate 202 is hinged to a front baffle 301 for limiting the material. A limiting spring 302 is symmetrically arranged inside the support plate 202. One end of the limiting spring 302 is provided with a positioning plate 303 for positioning the material.

The transport and lifting assembly 2 further includes a connecting plate 204, a winding rod 206, a connecting rod 208, a threaded rod 209 and a driving motor 210;

Both sides of the supporting plate 202 are provided with connecting plates 204 for positioning the wire rope 207. The top of the mounting frame 205 is provided with a driving motor 210 for driving the supporting plate 202 to move. The driving motor 210 is electrically connected to the output end of the external power supply. The output shaft of the driving motor 210 is fixedly connected with a threaded rod 209. The outer side of the threaded rod 209 is threadedly connected to the supporting plate 202 to facilitate driving the supporting plate 202 and the material to move. The outer side of the threaded rod 209 is fixedly connected with a connecting rod 208 for transmission through a bevel gear set. The bevel gear set consists of three mutually meshing bevel gears. One side of the connecting rod 208 and located inside the mounting frame 205 is fixedly connected with a winding rod 206 for winding the wire rope 207.

Move the mobile base 1 to a suitable position, start the drive motor 210, and the drive motor 210 drives the threaded rod 209 to rotate. The threaded rod 209 drives the load-bearing plate 202 and the material to be lifted through the threads on the surface. At this time, the side baffle 203 slides on one side of the fixed plate 201. At the same time, the threaded rod 209 drives the connecting rod 208 to rotate through the bevel gear set, and the connecting rod 208 drives the winding rod 206 to rotate. While the load-bearing plate 202 moves, the wire rope 207 is synchronously wound to ensure the stability and safety of the movement of the load-bearing plate 202.

The limiting fixing assembly 3 also includes a limiting rod 304, a return spring 305 and a limiting groove 306;

The side baffle plate 203 is internally slidably connected with a return spring 305, and the return spring 305 is internally connected with a limit rod 304 for fixing the front baffle plate 301. The outer side of the limit rod 304 is embedded in the limit groove 306 to facilitate fixing the front baffle plate 301 and ensure the safety performance of material lifting. The limit grooves 306 are symmetrically arranged inside the front baffle plate 301.

Pull the two limit rods 304 to separate the limit rods 304 from the limit slots 306, then the front baffle plate 301 can be rotated to place the material on top of the carrying plate 202. At this time, the material squeezes the two positioning plates 303, and the limit springs 302 are deformed. The reset performance of the limit springs 302 drives the positioning plates 303 to fit the two sides of the material to position the material. After the material is fixed, the front baffle plate 301 is rotated and the limit rod 304 is pulled at the same time. The limit rod 304 squeezes the reset spring 305. When the limit rod 304 is released, the rebound force of the reset spring 305 drives the limit rod 304 to move to the inside of the limit slot 306 to fix the front baffle plate 301, thereby avoiding sliding and collision during the lifting process and ensuring the quality of the material.
