Abstract
The utility model relates to a coiling block of a mine elevator. The coiling block of the mine elevator comprises a main shaft. A cylinder shell is externally arranged on the main shaft. Multiple connection plates are axially arranged on the main shaft. Two sides of each connection plate are connected with clamping plates through bolts. A supporting plate is arranged in two corresponding clamping plates in a clamped mode. Through holes are formed in the supporting plate. The clamping plates are connected with the supporting plate through bolts. The supporting plate is welded with the cylinder shell. As a sleeve is removed, the supporting plate is used fro replacing a supporting spoke and an oval through hole is formed in the supporting plate to reduce weight, rotational inertia of the coiling block of the mine elevator is greatly reduced and easy to control. The supporting plate is used for replacing the supporting spoke and the supporting plate is continuously welded with the cylinder shell so that strength is high, deformation due to welding is little and large deformation of the cylinder shell due to concentrated stress is avoided. As the supporting plate is arranged on the main shaft in a clamped mode through bolts and welded with the cylinder shell, uneven inner stress due to welding of two sides of the supporting plate is avoided, the strength of the supporting plate is large and the supporting plate is not prone to breakage, safe and reliable.
Description
Technical field
The utility model relates to a kind of mine hoist reel.
Background technology
Mine hoist is a kind of ground that is installed in, and drives the elevating gear of lifting container along pit shaft or ramp operation by means of steel rope.The reel of existing mine hoist comprises main shaft, outside main shaft, be provided with barrel shell, on main shaft, be provided with stay bearing plate to be connected barrel shell with barrel shell end positions corresponding position, between main shaft and barrel shell, be provided with sleeve, on sleeve, be provided with the support spoke, described sleeve and support between the spoke, support between spoke and the barrel shell and weld.Shortcoming in this structure is: 1, owing to sleeve is set as supporting media, the rotor inertia of mine hoist reel is big, and is wayward.2, support intermittently welding between spoke and the barrel shell, solder joint is many, stress is big, the deformation that produces in welding process accumulates, and causes barrel shell to be out of shape significantly.3, support upper and lower all employing of spoke and be welded to connect, the internal stress inequality, and it is low to support spoke intensity, and easily rupture in its junction.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly is connected firmly, not yielding, mine hoist reel that rotor inertia is little, easy to control, safe and reliable.
The utility model is achieved in that
A kind of mine hoist reel, comprise main shaft, outside main shaft, be provided with barrel shell, its special character is: described main shaft upper edge is axially arranged with a plurality of connecting panels, there are clamping plate both sides at each connecting panel by bolted connection, are folded with stay bearing plate in cooresponding two clamping plate, are provided with through hole on stay bearing plate, described clamping plate and stay bearing plate are by bolted connection, and described stay bearing plate and barrel shell weld.
Described through hole is a Long Circle, with economical with materials, and cost-cutting.
The beneficial effects of the utility model are:
1, owing to reduced sleeve, and adopt stay bearing plate to replace supporting spoke, and offer elliptical hole with expendable weight on stay bearing plate, the rotor inertia of mine hoist reel reduces greatly, and is easy to control.
2, adopt stay bearing plate to replace supporting spoke, successive welding between stay bearing plate and the barrel shell, the intensity height, the deformation that causes during welding is little, has avoided stress to concentrate and has caused barrel shell to be out of shape significantly.
3, owing to establish stay bearing plate by bolt clip on main shaft, described stay bearing plate and barrel shell welding avoided stay bearing plate to cause the internal stress inequality because of the both sides welding, and stay bearing plate intensity are big, and easy fracture is not safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Among the figure: main shaft 1, connecting panel 101, clamping plate 2, bolt 3, stay bearing plate 4, through hole 401, barrel shell 5.
The specific embodiment
As shown in the figure, this mine hoist reel has a main shaft 1, is axially arranged with a plurality of connecting panels 101 in described main shaft 1 upper edge.Both sides at each connecting panel are connected with clamping plate 2 by bolt 3, in cooresponding two clamping plate 2, be folded with stay bearing plate 4, on stay bearing plate 4, along the circumferential direction be evenly equipped with a plurality of through holes 401, in the present embodiment, described through hole 401 is a Long Circle, described clamping plate 2 are connected by bolt 3 with stay bearing plate 4, are welded with barrel shell 5 on the described stay bearing plate 4.
Claims (2)
1. mine hoist reel, comprise main shaft, outside main shaft, be provided with barrel shell, it is characterized in that: described main shaft upper edge is axially arranged with a plurality of connecting panels, there are clamping plate both sides at each connecting panel by bolted connection, are folded with stay bearing plate in cooresponding two clamping plate, are provided with through hole on stay bearing plate, described clamping plate and stay bearing plate are by bolted connection, and described stay bearing plate and barrel shell weld.
2. mine hoist reel according to claim 1 is characterized in that: described through hole is a Long Circle.
