Abstract
Description
Technical Field
[0001] This application relates to the field of building construction, specifically to a hoisting device with a parapet wall protection device. Background Technology
[0002] In lifting mechanisms, suspended platforms are a common type of equipment, primarily using steel wire ropes as the lifting and load-bearing components. The safety performance of the steel wire rope directly affects the safety performance of the entire equipment. Throughout the lifespan of the steel wire rope, wear between the concrete structure and the rope can cause partial breakage and splitting of the wire strands, potentially leading to the complete breakage of the rope, thus posing a significant threat to safe production. Currently, in most construction processes, the steel wire rope is directly in contact with the parapet wall or roof corner of the concrete structure. However, the movement of the steel wire rope through these areas causes considerable wear. Utility Model Content
[0003] The purpose of this utility model is to provide a hoisting device with a parapet wall protection device, in order to solve the technical problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A hoisting device with a parapet wall protection device includes an electric hoisting assembly and a protective frame secured to the parapet wall. The electric hoisting assembly includes a motor and a hoisting rope. The protective frame comprises an inverted U-shaped frame symmetrically arranged on both sides and angle steel protective components for connecting the two inverted U-shaped frames. The slots of the two angle steel protective components are respectively secured to the two external corners of the upper surface of the parapet wall. The inverted U-shaped frame includes vertical rods and right-angled triangular limiting frames located on both sides of the parapet wall, and a horizontal rod connecting the two vertical rods and the right-angled triangular limiting frames on the upper surface of the parapet wall. A fixed pulley is provided on the angle steel protective component located inside the parapet wall, and an ear plate is provided on the angle steel protective component located outside the parapet wall. The hoisting rope passes between the two ear plates.
[0006] More preferably, a pad is connected to the lower part of the vertical rod, the motor is fixed on the pad, and the pad is fixed on the roof panel.
[0007] Furthermore, the outer angle steel protective component is fixedly connected to the right-angled triangular limit frames on both sides, and the right-angled triangular limit frames are bolted to the crossbar. The right-angled triangular limit frames are fixed at different positions on the crossbar to make the distance between the right-angled triangular limit frames and the vertical bar adjustable.
[0008] Furthermore, the outer angle steel protective piece is detachably connected to the right-angled triangular limit frame on both sides, and a limit rod is also provided between the ear plates on both sides.
[0009] Furthermore, an oblique reinforcing rod is provided between the vertical rod and the pad block.
[0010] In addition, the inverted U-shaped frame is made of channel steel.
[0011] More preferably, the outer corner of the angle steel protective component is an arc-shaped joint.
[0012] Compared with the prior art, this utility model has the following features and beneficial effects:
[0013] This application effectively prevents the wire rope from moving left or right. A separate wire rope or limiting rod passes through the fixing hole in the ear plate to prevent the wire rope from exceeding the fixing plate, providing good safety performance. When the angle steel protective component is installed at a corner, the angle steel is bent at a right angle and can fit tightly against the parapet wall or roof corner. The structure and installation are simple; only the anti-wear device needs to be placed at the corner of the parapet wall, making it economical and practical. It can also be recycled and reused after construction. Attached Figure Description

[0019] Example 1
[0020] A hoisting device with a parapet wall protection device, such as Figure 1 and 2As shown, the system includes an electric hoisting assembly 1 and a protective frame 3 secured to the parapet wall 2. The electric hoisting assembly 1 includes a motor 11 and a hoisting rope 12, which is generally a steel wire rope. The protective frame 3 includes an inverted U-shaped frame symmetrically arranged on both sides and an angle steel protective member 31 for connecting the two inverted U-shaped frames. The slots of the two angle steel protective members are opposite each other and secured to the two external corners of the upper end face of the parapet wall 2. The inverted U-shaped frame includes vertical rods 32 and right-angled triangular limit frames 33 located on both sides of the parapet wall 2, and a horizontal rod 34 connecting the two vertical rods 32 and the right-angled triangular limit frames 33 on the upper end face of the parapet wall 2. The angle steel protective member 31 located on the inner side of the parapet wall 2 is provided with a fixed pulley 36. The hoisting rope passes through the fixed pulley 36 and then passes between the two ear plates 37 and hangs down to hoist the object.
[0021] The angle steel protective component 31 located on the outside of the parapet wall 2 is provided with ear plates 37. The suspension rope 12 passes between the ear plates 37 on both sides. The motor 11 can be integrated with the protective frame body 3. Specifically, the lower part of the vertical rod 32 is connected to a pad 35. The motor is fixed on the pad 35. The pad 35 is fixed on the roof panel. The pad 35 and the roof panel are connected by expansion bolts or pre-drilled holes with bolts. Only the pad is fixedly connected to the building structure. The protective frame body 3 only needs to be clamped to the parapet wall. Specifically, the outer angle steel protective component 31 is fixedly connected to the right-angled triangular limit frame 33 on both sides. The right-angled triangular limit frame 33 is bolted to the horizontal bar 34. The right-angled triangular limit frame 33 is fixed at different positions on the horizontal bar 34 to make the distance between the right-angled triangular limit frame 33 and the vertical rod 32 adjustable to adapt to the parapet wall structure of different widths, so that the entire protective frame body is tightened on the entire parapet wall.
[0022] Example 2
[0023] Based on Embodiment 1, the outer angle steel protective component 31 is detachably connected to the right-angled triangular limit frame 33 on both sides, which facilitates the replacement of the angle steel protective component 31. A limit rod is also provided between the ear plates 37 on both sides. The limit rod can prevent the wire rope from jumping out of the limit component. An oblique reinforcing rod 38 is provided between the vertical rod 32 and the pad 35. The inverted U-shaped frame is made of channel steel. The external corner of the outer angle steel protective component 31 is an arc-shaped joint to prevent the absolute right angle from abrading the hoisting rope. The thickness and height of the parapet wall generally do not change much. The distance between the right-angled triangular limit frame 33 and the vertical rod 32 is adjustable, and the thickness of the pad is adjustable to increase the adaptability of the entire hoisting equipment.
