Description

Technical Field

[0001] The present application relates to the technical field of lifting equipment, and specifically discloses an electric hoist lifting device. Background Art

[0002] Electric hoist is a kind of lifting equipment installed on overhead crane and gantry crane. Electric hoist has the characteristics of small size, light weight, simple operation and easy use. It is used in industrial and mining enterprises, warehouses, docks and other places.

[0003] Existing building construction typically requires the construction of molds. For example, to construct structures like air conditioning panels and outdoor bay windows, the molds must be constructed and concrete poured in-situ, allowing the concrete to solidify within the molds to form the panels and bay windows. Due to the height of the buildings, electric hoists are typically used to hoist the molds. Currently, electric hoists typically use a hook attached to a rope, which is then used to tie the object to be hoisted. The rope is then attached to the hook for hoisting.

[0004] For long plate-like components or steel structure components, it is usually necessary to tie ropes at both ends of the components and then hang the ropes on the hooks of the electric hoist, causing the ropes of the tied components to be in an inclined state. In order to prevent the ropes from sliding along the surface of the component, the ropes need to be wrapped around the component multiple times and protected with anti-slip pads and other components. As a result, in the process of lifting long plate-like components or steel structure components, the entire process is cumbersome and complicated, and the efficiency is low. Therefore, in view of this, the inventor provides an electric hoist lifting device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that in the process of traditional electric hoists lifting long plate-shaped components or steel structure components, the binding process of the components is cumbersome and complicated, resulting in reduced lifting efficiency.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides an electric hoist lifting device, including a connecting rod arranged on the lifting rope of the electric hoist, a connecting block vertically slidably connected to the connecting rod, a first hook arranged on the connecting block, a horizontal plate detachably connected to the first hook and a second hook symmetrically arranged on both sides of the horizontal plate, a cavity is provided in the connecting block, the bottom of the connecting rod extends into the cavity and is provided with a sliding roller, and both ends of the horizontal plate are provided with hanging ropes that fit the surface of the sliding roller.

[0007] The principles and effects of this basic solution are:

[0008] Compared with the prior art, the present invention sets a connecting rod and a connecting block so that the first hook hangs the cross plate, and the cross plate hangs the two second hooks at the same time. Therefore, when the electric hoist is used to lift the long plate-like components or steel structure components, the two ends of the components are tied with ropes respectively and the ropes are hung to the two second hooks respectively. Then, by starting the electric hoist, the hanging rope is tightened and the cross plate is lifted upward, and the long plate-like components or steel structure components can be lifted. At the same time, due to the cooperation between the hanging rope and the sliding roller, the sliding roller can be kept at the center of the hanging rope when moving upward, thereby maintaining the balance of force on the two ends of the cross plate, avoiding the tilting of the cross plate, and ensuring the stability of the long plate-like components or steel structure components during the lifting process.

[0009] Furthermore, the bottom of the connecting rod extends into the cavity and is provided with a connecting plate. A return spring is provided between the top of the connecting plate and the top surface of the cavity, sleeved around the circumference of the connecting rod. Lugs for mounting the sliding roller are symmetrically provided at the bottom of the connecting plate. The provision of the connecting plate and the elastic fit of the return spring facilitate contact between the connecting rod and the connecting block, while also preventing the connecting rod from separating from the connecting block. The lugs provide a foundation for mounting the sliding roller.

[0010] Furthermore, the sliding roller is vertically slidably connected to the cavity, and vertical slide grooves are symmetrically provided on both sides of the cavity. The sliding roller is coaxially connected to a sliding rod, and the ends of the sliding rod are respectively slidably connected to the slide grooves on both sides. The cooperation between the slide groove and the sliding rod can limit and guide the relative sliding of the connecting rod and the connecting block.

[0011] Furthermore, a fixed roller is located directly above the sliding roller within the cavity. When the hanging rope is tightened, the sliding roller and the fixed roller come into contact and squeeze the hanging rope. The sliding and fixed rollers cooperate to squeeze and lock the hanging rope, preventing it from shaking during the lifting process and ensuring smooth lifting of long plate-like components or steel structures.

[0012] Furthermore, the fixed roller is provided with connecting shafts fixedly connected to the inner wall of the cavity at both ends, and the ear plates are symmetrically provided with through grooves for allowing the connecting shafts to pass through. The connecting shafts and through grooves are provided to prevent the connecting ear plates from colliding with the fixed roller during vertical movement.

[0013] Furthermore, an elastic pad is provided on the outer wall of the sliding drum. When the hanging rope is tightened, the elastic pad is squeezed by the fixed drum and the sliding drum. The elastic pad can further improve the locking effect of the hanging rope, thereby further improving the stability during the lifting process of long plate-like components or steel structures.

[0014] Furthermore, the top of the connecting rod extends out of the cavity and is provided with a limit plate, which is connected to the lifting rope of the electric hoist. The limit plate can limit the position of the connecting rod. BRIEF DESCRIPTION OF THE DRAWINGS
