Specific embodiment:
Spoir elevator of the present invention, it is characterised in that: including pedestal (1), the middle part connecting elements (2) being located on pedestal (1) and
The top connecting elements (3) connecting with intermediate attachment member, the pedestal (1) include two round steel in cross-shaped welding
Pipe (1-2) and four channel steels (1-1) being welded between round steel pipe (1-2) two-by-two, wherein between first group of round steel pipe two-by-two
In addition it is welded with the 5th channel steel (1-1-1), that first slot of root in four channel steels between first group of the round steel pipe two-by-two
It is connected with intermediate channel steel (1-1-3) between steel (1-1-2) and the 5th channel steel (1-1-1), the first channel steel (1-1-2), the 5th
Channel steel (1-1-1) connect with intermediate channel steel (1-1-3) to be formed it is I-shaped；The middle part connecting elements (2) includes lower bracket (2-
1), square floor (2-2), disk (2-3) and sleeve (2-4)；The square floor (2-2) is bolted to the first channel steel (1-
1-2), the 5th channel steel (1-1-1) connect the i-shaped beams upper surface formed, the lower bracket (2- with intermediate channel steel (1-1-3)
It 1) is tubular rod, lower end is welded on square floor (2-2), and the disk (2-3) is welded on the upper end of lower bracket (2-1),
The sleeve (2-4) passes through in the middle part of disk (2-3) and is welded and fixed；The top connecting elements (3) include upper bracket (3-1),
Capstan winch pedestal (3-2) and promotion boom (3-3), the upper bracket (3-1) are in pipe sleeve shape, are socketed in sleeve (2- by bearing
4) on, square tube is welded in first side of upper bracket (3-1), as the capstan winch pedestal (3-2) of hand capstan (4), second side welding
It is promoted boom (3-3), promotes boom upper end and weld two pulley baffles (5) and be mounted between two pulley baffles (5)
Pulley (6).
During transportation, entire elevator can be split into pedestal (1), middle part connecting elements (2), top connecting elements
(3) three entirety reduce the solid space and single component weight of its occupancy, facilitate entrucking transport and artificial (5 kilometers of short distance
It is interior) it carries.
Elevator is matched before use, need to cover upper bracket (3-1) on lower bracket sleeve (2-4) by two bearings (7)
It closes, upper bracket (3-1) can circumferentially rotate on lower bracket (2-1), and after the completion of realizing that hanging basket (5) are promoted, the earthwork is directly shifted
To the function on hole side, to prevent operator in the personal risk of near coal-mine operation.
The present invention can be fixed on hole side by easy means, when eliminating the promotion of current artificial digging pile spoir, operator,
Equipment crashes into the security risk in hole, while novel spoir lifting machinery prevents hanging object from crashing into hole, make for autonomous brake function
Entire spoir lifting construction process more specification, safety, controllably.
During setting up elevator, round steel pipe (1-2) interpolation spreading steel pipe (1-3) of above-mentioned pedestal, to be inserted by control
The length of spreading steel pipe (1-3) makes the midpoint (A) of the overhanging farthest point line of long steel pipe (1-3) fall in elevator lifting range (B)
In addition, it can cancel in this way to the counterweight for promoting drive end unit, keep entire dress by elevator service load and self weight
The stability set avoids elevator because counterweight is unreasonable, and overthrow accident occurs.
Further, the lower part of above-mentioned sleeve (2-4) has step, to be used to support lower bearing inner ring, the upper bracket
The tubular inner wall upper and lower end of (3-1), which is respectively provided with, extends out step, to be used to support the outer ring of upper and lower bearing, the upper bracket
The clamp nut that the upper surface that the top of (3-1) is located at upper bearing (metal) is covered with gasket and connect with sleeve (2-4) threaded upper ends
(8), to prevent the play of elevator in axial direction.
Further, above-mentioned upper and lower bearing selects thrust ball bearing (7-2) and deep groove ball bearing (7-1) respectively.Two axis
It holds and selects thrust ball bearing (7-2) and deep groove ball bearing (7-1) that can both make to mention in the earthwork using this combination respectively
Upper and lower bracket mating part can bear biggish axial force when elevator is dynamic, and can be in earthwork rotational motion, circumferencial direction rotation
Compare flexibly, in addition this combination is relatively common in engineer application, can further promote the reliability of whole device.
Further, above-mentioned disk (2-3) has the outer rim for protruding from lower bracket (2-1), has 3 limits in the outer rim
11(-135 ° of notch, 0 °, 135 ° of position), the periphery wall of the upper bracket (3-1) is welded with night bolt (9), the night bolt
(9) lower end can limit in spacing breach.When elevator is when doing lifting motion, the pin shaft of night bolt falls in 0 ° of notch
In, it can prevent elevator upper and lower part from generating circumferentially opposed movement, promote the stability of whole device.Promoting fortune simultaneously
It is dynamic complete after circular motion in, the circle on top can be circumferentially rotated in the range of being limited in 0 ± 135 °, prevent top without
The rotation of limitation generates security risk.
Further, the wirerope of above-mentioned hand capstan (4) winding output bypasses pulley (6), and is connected with hanging basket (10).
Hand capstan (4) has ratchet friction plate protective device, and for wirerope one ends wound on capstan winch, the other end passes through suspension hook and hanging basket
(10) it connects, when avoiding operator's work fatigue, when operation error, capstan winch has active brake function, prevents hanging object from dropping
Injure the risk of operating personnel in cheating by a crashing object.
Humanization designing of the present invention, it is convenient for disassembly and assembly, it is convenient for manual handling, it is easy to operate, it need to only pass through easy means
It is fixed in hole side to use, and has the function that spoir is transferred to hole side, be particularly suitable for small-sized, dispersion, and be commonly located at
The form of construction work of the artificial digging pile of remote districts, in addition when operator's work fatigue, operation error, which has master
Dynamic brake function prevents hanging object tenesmus from injuring operating personnel in hole by a crashing object.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification, is all covered by the present invention.
