Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a safety lifting device for building operations. Background Technology

[0002] There are various types of safety lifting devices used in construction operations. These include construction hoists, simple lifting platforms, and electric suspended platforms. One existing type of electric scaffolding is suitable for exterior wall construction, interior decoration, door and window installation, and steel structure construction. In use, the scaffolding is moved to the construction position. A stable base is installed on all four sides of the scaffolding's lower end. Rotating the rotating rod brings the base into contact with the ground, preventing scaffolding from swaying and improving its safety.

[0003] However, when installing the support rods used to fix the chassis, the support rods and diagonal braces need to be bolted to the side of the scaffold, which is inconvenient to dismantle and has low construction efficiency. Therefore, it is necessary to provide a safe lifting device for construction operations to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a safe lifting device for construction operations, in order to solve the problem mentioned in the background art that when installing the support rod for fixing the chassis, the support rod and the diagonal tie rod need to be bolted to the side of the scaffold, which is inconvenient to dismantle and has low construction efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a safety lifting device for construction operations, comprising:

[0007] An electric scaffolding, comprising columns, support rods, diagonal braces, and U-shaped connectors, wherein the support rods are connected to the side of the columns, one end of the diagonal braces is rotatably connected to one end of the upper surface of the support rods, and the U-shaped connectors are rotatably connected to the other end of the diagonal braces;

[0008] The connecting assembly includes a square tube, a through hole, a T-shaped insert, a spring, a connecting tube, a first waist hole, and a second waist hole. The square tube is fixed to the middle and lower end of the side of the column. The through hole is opened in the middle of the side of the square tube. The T-shaped insert is inserted into the through hole. The spring is sleeved on the T-shaped insert, with one end fixed to the T-shaped insert and the other end fixed to the side of the square tube. One end of the connecting tube is welded to one end of the U-shaped connector. The first waist hole is opened in the middle of the side of the connecting tube, and the second waist hole is opened in the middle of one end of the support rod.

[0009] Furthermore, one end of the support rod with the second waist hole is inserted into the square tube at the lower end of the column, and the connecting tube is inserted into the square tube in the middle of the column.

[0010] Furthermore, the T-shaped inserts located on the middle and lower square tubes are respectively inserted into the first waist hole and the second waist hole.

[0011] Furthermore, the electric scaffold also includes a base, which is fixed to the lower end of the column, and the upper middle part of the base is slidably connected to the working platform.

[0012] Furthermore, it also includes a reinforcement component, which includes a support tube, a first groove, a second groove, and a limiting block. The support tube is sleeved on the square tube, the first groove is opened at one end of the support tube, the second groove is opened at the other ends of both sides of the support tube, and the limiting block is fixed on both sides of one end of the square tube.

[0013] Furthermore, the first groove is located outside the T-shaped insert and the spring, and the second groove is movably connected to the outside of the limiting block.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through the set connecting components, allows for the removal of the support rod and diagonal tie rod. One end of the support rod and connecting pipe is inserted into the upper and lower square tubes. Then, the T-shaped insert rod in the through hole is pulled up in sequence, pushing the support rod and connecting pipe into the square tube. Releasing the T-shaped insert rod causes the spring to retract, driving the T-shaped insert rod to be inserted into the first waist hole and the second waist hole respectively. At this point, the position of the chassis can be adjusted. This setting facilitates quick disassembly of the support rod and diagonal tie rod, which helps to improve construction efficiency.

[0016] II. In this utility model, after the support rod and diagonal tie rod are installed by setting the reinforcement components, the support tube is pulled to drive the first groove and the second groove to move until the end of the second groove is in contact with the limiting block. This setting can increase the connection length between the square tube and the support rod and diagonal tie rod, and improve the connection stability. Attached Figure Description
