Description

Technical Field

[0001] The invention relates to the technical field of construction equipment, and in particular to a chain hoist. Background Art

[0002] With the rapid development of the construction industry, hoists are increasingly widely used in various construction equipment. The existing ones have a large overall weight and volume, which is not conducive to on-site installation, disassembly and transportation. Moreover, the overall structural stability after installation is poor, which is easy to cause construction accidents during construction. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a chain hoist with small overall weight and volume, convenient on-site installation, disassembly and transportation, and high structural stability after installation.

[0004] The embodiment of the present application provides a chain hoist, including a box body, a driving device, a driving sprocket, a guide wheel, a cruise wheel, a lifting chain and a derailleur plate. The box body includes a left box body and a right box body; the left box body and the right box body are provided with a connecting flange; the left box body and the right box body are fixedly connected by bolts, and the left box body and the right box body are symmetrically provided with a plurality of connecting holes on the right side, and the plurality of connecting holes are convenient for being fixedly connected with the lifting object by bolts; the driving sprocket, the guide wheel, the cruise wheel and the derailleur plate are placed in the box body, and the driving device is placed on one side of the box body and fixedly connected to the box body by bolts. There are multiple cruise wheels, which are symmetrically distributed on both sides of the guide wheel, and the driving sprocket is placed at the center of the two cruise wheels on one side. The lifting chain is meshed with the guide wheel and the driving sprocket, and passes through the chain slot of the box body at one end, and passes through the chain slot of the box body at the other end through the guide wheel and the driving sprocket.

[0005] In a chain hoist provided by an embodiment of the present application, a plurality of guide wheels can be provided, which are symmetrically arranged on one side of the driving sprocket. The cruise ship is provided with four guide wheels symmetrically distributed on both sides of the guide wheel.

[0006] A chain hoist provided in an embodiment of the present application has needle bearings on both sides of a guide wheel and a driving sprocket to reduce friction during operation.

[0007] In a possible implementation of the present application, the upper and lower ends of the lifting chain are anchored on the building object, and the box is connected to the lifting object by bolts. When the driving sprocket rotates, the box is driven to move and lift up and down. Since the two ends of the lifting chain are tightened and anchored, the lifting process is more stable and not easy to shake.

[0008] In a possible implementation of the present application, a chain derailleur plate is provided on one side of the chain outlet slot of the box body to prevent the chain from hinged during the lifting process, thereby enabling a more stable lifting operation. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] Chain hoists are increasingly widely used in various construction equipment. The existing ones have a large overall weight and volume, which is not conducive to on-site installation, disassembly and transportation. Moreover, the overall structural stability after installation is poor, which can easily cause construction accidents during construction.

[0019] The chain hoist in the embodiment of the present application has a new structural design. The two ends of the lifting chain are tightened and anchored to the building object to prevent shaking during the lifting process. Compared with other hoists on the market, the lifting is more stable. Due to the simple structure and fewer parts required, its size is smaller and it is convenient for transportation and carrying.

[0020] Reference Figure 1 The embodiment of the present application provides a chain hoist, including a box body, a driving device, a driving sprocket 5, a guide wheel 10, a cruise ship 7, a lifting chain 9 and a chain plate 8; wherein,

[0021] Reference Figure 2 The box body includes: a left box body 3 and a right box body 4, the left box body 3 and the right box body 4 are provided with a connecting flange 31, and the right sides of the left box body 3 and the right box body 4 are symmetrically provided with a plurality of connecting holes 33, and the plurality of connecting holes 33 are convenient for being fixedly connected with the lifting object by bolts; the upper and lower ends of the left box body 3 and the right box body 4 are respectively provided with a chain outlet groove 32;

[0022] Reference Figures 1 to 3 The driving sprocket is arranged in the box body; the driving sprocket 5 is fixedly connected to the reduction device 2 through a key; the driving sprocket 5 is provided with needle bearings 6 at both ends along the central axis; the guide wheel 10 is arranged in the box body; the guide wheel 10 is symmetrically arranged on one side of the driving sprocket 5; the cruise ship 7 is symmetrically arranged in the box body; the cruise ship 7 is symmetrically distributed on both sides of the guide wheel 10; the lifting chain 9 is meshed with the guide wheel 10 and the driving sprocket 5, and passes through the chain groove 32 of the box body at one end, and passes through the guide wheel 10 and the driving sprocket 5 to pass through the chain groove 32 of the box body at the other end.

[0023] It can be understood that the driving device is fixed to the box by bolts, the two ends of the lifting chain 9 are anchored on the building object, and the box is connected to the lifting object by bolts. When the driving sprocket 5 rotates, it drives the box to move up and down to implement up and down lifting. Since the two ends of the lifting chain are tightened and anchored, the lifting process is more stable and not easy to shake.
