Description

Technical Field

[0001] The invention relates to the technical field of mine hoisting equipment, and in particular to a compact hoist drum. Background Art

[0002] The well drilling hoist plays an important role during the entire shaft construction. After completing the well drilling task, the well drilling hoist often needs to be moved to the next construction site for operation. In order to improve the installation and disassembly efficiency of the well drilling hoist, an easy-to-relocate well drilling hoist will be used. This hoist is installed as a whole on a large integral base, and a simple house is set around the base. It is transported by truck and can be placed in place by simply lifting it by a crane at the work site, saving manpower and material resources and shortening the disassembly and assembly time. However, the easy-to-relocate well drilling hoist generally adopts an ordinary drum structure, the brake disc and drum have large external dimensions, and the disc brake device has a large layout size, resulting in the hoist system and the overall base occupying a large space and a large weight, which increases the difficulty of passing and load-bearing capacity during transportation. At the same time, the raw materials are consumed more, making the overall cost of the system high. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a compact hoist drum, in which the hoist system and the overall base occupy less space, are lighter in weight, and are convenient for disassembly, assembly and transportation.

The reel body III includes a left plate III, a right plate III, a cylinder shell III and a right wheel hub. The left plate III and the right plate II are connected by bolts to arrange the reel body III on the right end of the reel body II. The right wheel hub is concentrically arranged with the left plate III in the inner hole of the left plate III. The brake disc is connected to the left side plate I and the right side plate III respectively through bolts, and the brake disc is arranged on the outer ends of the reel body I and the reel body III respectively.

[0005] Specifically, rib plates I are evenly arranged along the circumference between the left plate I and the right plate I and on the inner wall of the cylinder shell I.

[0006] Specifically, rib plates II are evenly arranged between the outer circumference of the cylinder shell I and the right side plate I.

[0007] Specifically, rib plates III are evenly arranged between the left plate III and the right plate III and on the inner wall of the cylinder shell III along the circumference.

[0008] Specifically, rib plates IV are evenly arranged between the outer circumference of the cylinder shell III and the left side plate III.

[0009] Specifically, a waist-shaped rope outlet hole is provided on the left side plate III, and a clamp is provided at a position corresponding to the waist-shaped rope outlet hole.

[0010] Specifically, 2 to 4 waist-shaped manholes are provided on the right side plate I and the left side plate III.

[0012] Due to the adoption of the above-mentioned technical solution, the present invention has the following advantages: The compact hoist drum of the present invention adopts a three-section optimized structure. The outer diameter of the drum shell of the left and right sections of the drum is smaller than the outer diameter of the drum shell of the middle section of the drum. Compared with ordinary drums, the outer circle size of the brake disc is smaller, and the disc brake device is arranged more compactly, reducing the space occupied by the entire hoist system and the overall base, making the weight of the hoist and the overall base lighter without weakening the lifting capacity, reducing the difficulty of transportation, and at the same time reducing the use of raw materials and reducing equipment investment costs.
