Description

Technical Field

[0001] This utility model relates to the technical field of steel wire strength testing equipment, specifically a steel wire strength testing device for a mine hoist. Background Technology

[0002] Mine hoists are key pieces of equipment in mining production used for the vertical or inclined transport of minerals, equipment, and personnel. They are widely used in underground mining fields such as coal mines, metal mines, and non-metal mines. The main driving method of mine hoists relies on the dragging of steel wire ropes. During the production of steel wire ropes, it is necessary to test the tensile strength of the steel wires using strength testing equipment. However, in existing technologies, the steel wire ropes need to be bound during testing, but the relatively rounded surface of the steel wire ropes makes binding inconvenient and prone to pull-out during testing. Therefore, improvements to the existing technology are needed. Utility Model Content

[0017] Please see Figure 1-5 A power box 3 is fixedly installed on the upper end of the drive column 2. A connection hole 10 is opened inside the mounting base 9, into which a steel wire rope can be inserted. The clamping frame 15 contacts the support frame 11. The threaded frame 14 is slidably connected to the mounting plate 7. The threaded frame 14 can drive the clamping frame 15 to move. Two symmetrically distributed guide bars 17 are fixedly connected to the upper end of the mounting plate 7. Both guide bars 17 are slidably connected to the threaded frame 14. The guide bars 17 can guide the movement of the threaded frame 14.

[0018] Please see Figure 1-5The stabilizing mechanism 8 includes a limiting wheel 81. The limiting wheel 81 is fixedly connected to the outer side of the screw 13. A fixing frame 82 is fixedly connected to the outer side of the mounting plate 7. A handle frame 83 is slidably connected inside the fixing frame 82.
