Description

Technical Field

[0001] This application relates to the field of elevators, and more particularly, to a hydraulic construction elevator equipped with a safety protection mechanism. Background Art

[0002] Construction elevators are usually referred to as construction hoists, but the definition of construction hoists is broader, and construction platforms also belong to the construction hoist series. A simple construction elevator consists of a car, a driving mechanism, standard sections, wall attachments, a chassis, a fence, an electrical system, etc. It is a construction machine often used for carrying people and goods in construction. Due to its unique box structure, it is both comfortable and safe to ride. Construction elevators are usually used in conjunction with tower cranes on construction sites.

[0003] The structure of the product can refer to a safety protection device for a construction elevator disclosed in Chinese Patent Document 202311152399.0, which solves the problems that it is difficult to adapt and install the safety protection device of the construction elevator on any elevator, and the assembled safety protection structure is usually prone to falling off, resulting in accidents. A safety protection device for a construction elevator includes a lifting mechanism. At a position near the front side of the top of the lifting mechanism, a protection door mechanism is movably inserted. At the rear side of the protection door mechanism, a protection outer frame mechanism is movably inserted. At the rear side of the protection outer frame mechanism, an elevator chassis is movably installed. Through the setting of the lifting mechanism, the four end corners of the lifting platform can be inserted into the internal insertion chute, so that the U-shaped base and the positioning rod are installed at the four end corner positions of the lifting platform with any size, enabling the device to be adapted to the installation of lifting platforms with different sizes and facilitating the installation and combination of the device for elevators of different models or sizes.

[0004] However, in this patent, since it is only transported by a suspension rope, it may cause shaking during the ascending process, thus affecting safety. And when materials are sent into the box, due to the possible presence of some impurities, if they are not filtered, it will affect the quality of the materials.

[0005] Now, a hydraulic construction elevator equipped with a safety protection mechanism is provided. Summary of the Invention

[0006] This part of the content of this application is used to briefly introduce concepts, which will be described in detail in the subsequent detailed implementation part. This part of the content of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0007] To solve the technical problems mentioned in the above background art section, some embodiments of the present application provide a hydraulic construction elevator with a safety protection mechanism, including: a base; four support rods fixedly connected to the four corners of the bottom of the base; two mounting frames symmetrically fixedly connected to the base; chutes opened on the mounting frames; two sliders slidably mounted on the chutes; a connecting rod fixedly connected between the sliders; a lifting assembly arranged on the base for lifting the connecting rod; two pull ropes symmetrically fixedly connected to the connecting rod; a box body arranged below the connecting rod, with the other ends of the pull ropes fixedly connected to the box body, and two side plates of the box body respectively hinged to the box body; fixing bolts threadedly connected to the side plates of the box body, and the fixing screws threadedly connected to the box body; a limiting groove opened on the base and corresponding to the box body; two filter nets symmetrically arranged on the base, the filter nets being inclined, with the inclination directions of the two filter nets being opposite, and the filter nets corresponding to the box body; a feeding assembly arranged on the base and corresponding to the filter nets; a shaking assembly arranged on the base and used for shaking the filter nets.

When the materials enter the box body, the first servo motor can be started. Under the action of the first servo motor, the lead screw rotates. Under the action of the disc and the belt, the two lead screws rotate simultaneously, so that the slider drives the connecting rod to rise. And under the action of the pull rope, the box body rises. And under the action of the limiting strip being limited on the limiting cavity, the box body is prevented from shaking, with a safety factor. And when the feeding reaches a certain position, the two side plates of the box body can be opened through the fixing bolts to discharge the materials in the box body.

[0009] Furthermore, the lifting assembly includes a first servo motor, which is fixedly connected to the bottom of the base.
