Description

Technical Field

[0001] This utility model belongs to the field of hoisting technology, and in particular relates to a high-level hoisting machine that can prevent deformation of the intermediate section during hoisting. Background Technology

[0002] High-level bucket elevators specifically refer to bucket elevators with a high longitudinal lifting height, widely used in mining, rice and flour processing, construction, and port terminals. The main components of an elevator include an upper and lower head for loading and unloading, a middle casing for connection and sealing, running components housed within the middle casing, and a drive unit located in the upper head. Due to varying application scenarios, in addition to the upper and lower head and drive unit, the number of components in the middle casing and the length of the running components are often customized to meet specific requirements. Finally, assembly takes place on-site at the actual application location.

[0003] Chinese patent document CN212607482U discloses a sealing structure for a telescopic intermediate section of a hoist. This telescopic intermediate section is installed between the intermediate section and the tail section of the hoist. The telescopic intermediate section includes an upper part and a lower part, which are movably connected by a guide mechanism. Several sealing structures are provided at the movable connection between the upper and lower parts of the telescopic section. Each sealing structure includes an insert plate assembly and a socket assembly. The insert plate assembly has a sealing insert plate installed at the bottom of the upper part of the telescopic section. The socket assembly includes an outer sealing side plate and an inner sealing side plate arranged symmetrically. A first gap is formed between the outer and inner sealing side plates for the insertion of the sealing insert plate. The removable sealing structure achieves sealing at the connection of the telescopic section, effectively preventing dust leakage. Additionally, a pair of limiting strip structures are added to limit and seal the sealing insert plates.

[0004] Similar to the intermediate section of the hoist described in the aforementioned patent, the intermediate section requires hoisting using a crane during assembly. The conventional method is to directly lift it by using a hook to hold it above the round hole on the upper flange. However, the small contact area between the hook and the flange's round hole leads to stress concentration, easily causing flange deformation and resulting in poor sealing after subsequent assembly. Furthermore, while meeting the basic strength requirements for road transport and the intermediate section itself, individual intermediate sections are often quite tall. Manual labor is required to use ladders or raise the hook to secure it to the upper flange, thus presenting operational inconvenience. Utility Model Content

[0005] To overcome the technical problem in existing hoisting technologies where the hook gets caught in the round hole on the upper flange during the hoisting process of the intermediate section, which is not only inconvenient to operate but also causes flange deformation, one objective of this utility model is to provide a high-level hoist that can prevent deformation of the intermediate section during hoisting. This is achieved by setting a central flange protruding outwards in the middle of the intermediate section, and installing a removable flexible shroud at the lower end of the central flange. The shroud is positioned low for easy manual operation, allowing hoisting from the middle of the intermediate section. Simultaneously, the flexible shroud evenly distributes the force to all parts of the central flange, effectively preventing deformation of the intermediate section.

[0006] To achieve the above objectives, the present invention employs the following technical solution: a high-level hoist capable of preventing deformation of intermediate sections during lifting, comprising a longitudinally arranged tail section, a head section, and multiple intermediate sections disposed between the tail section and the head section; each intermediate section comprises a sheet metal tube body, two end flanges respectively disposed at both ends of the sheet metal tube body, and a central flange disposed in the middle of the outer periphery of the sheet metal tube body; wherein, a flexible shroud is detachably connected to the lower end of the central flange; selectable interlocking buckles are provided between the two ends of the shroud; at least one sling for connecting a crane hook is provided on the shroud.

[0007] Furthermore, the cross-section of the sheet metal tube is rectangular; a first support column is longitudinally arranged in each of the four corners of the sheet metal tube; the upper end of the first support column extends to the top of the sheet metal tube; a receiving area is arranged in the lower part of each of the four corners of the sheet metal tube; between two adjacent sheet metal tubes, the upper first support column abuts against the lower first support column.

[0008] Furthermore, the sling is provided with multiple positioning parts; each positioning part includes a positioning plate that is laterally slidably connected to the sling, two U-shaped hooks that are symmetrically arranged and longitudinally slidably connected to both sides of the positioning plate, and a hanging ring that is rotatably connected between the two U-shaped hooks; the opening of the U-shaped hook faces upward, and the width of the sling is greater than the opening depth of the U-shaped hook; the hanging ring is used to connect the sling.

[0009] Specifically, the upper end of the positioning plate is provided with an L-shaped hook, the end of which is located away from the sheet metal tube; multiple evenly distributed through holes are provided through the middle flange; the L-shaped hook can be selectively installed in the corresponding through hole.

[0010] Specifically, the U-shaped hook has an outwardly extending ear on the side away from the sheet metal tube; a pin is provided between the two outwardly extending ears to be rotatably connected to the hanging ring; and a longitudinal sliding groove is provided on the positioning plate to be longitudinally slidably connected to the pin.

[0011] Furthermore, the sheet metal tube body is provided with a plurality of evenly distributed reinforcing ribs along its outer periphery; the reinforcing ribs are integrally formed on the sheet metal tube body by bending sheet metal.

[0012] Specifically, the sheet metal tube body includes two welded tubes; the end flange and the middle flange are respectively disposed at both ends of the welded tubes.

[0013] Furthermore, the slings are four in number, and a molded frame is provided above each of the four slings. The molded frame is located on the hook. The intermediate section is located inside the molded frame.

[0014] Optionally, the lock is a rope tensioner.

[0015] Optionally, the latch is two selectable interlocking latches.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model has a central flange on the outer periphery of the middle section. When the middle section is lifted for installation, the force of the band surrounding the lower end of the central flange is evenly distributed throughout the central flange to prevent the middle section from being deformed by pressure. At the same time, the operating position is low, which is convenient for manual operation.

[0018] 2. This utility model has a first support column inside the intermediate section to facilitate the alignment and assembly between two adjacent intermediate sections; it also has reinforcing ribs on the outer periphery of the intermediate section and a second support column on the end flange, which increases the structural strength of the intermediate section and is suitable for hoists with higher heights.

[0019] 3. This utility model features a positioning plate that can be inserted into the central flange and a U-shaped hook that can slide relative to the positioning plate on the webbing. The positioning plate can prevent the webbing from detaching from the central flange due to stretching deformation or the stretching of the webbing caused by the movement margin of the buckle, thus improving safety. At the same time, the U-shaped hook causes the webbing to deform upward, so that the webbing is completely attached to the lower end of the central flange, dispersing the local force, making the force more uniform, and preventing deformation.

[0020] 4. The girder of this utility model adopts a modular design. The positioning plate and U-shaped hook are integrated with the girder and will not detach, making it easy to use. It can also adjust the relative position of the positioning plate according to the specific use situation, and is suitable for hoisting various types of intermediate sections.
