Abstract
The utility model discloses a gearless locking device for a hoist, and the gearless locking device comprises a rack. The bottom inside the rack is provided with a tray; a screw jack is arranged on the tray; a travel switch is arranged at the position, which is close to a screw jack strut, on the rack; a guide bracket is vertically arranged at the position, which corresponds to the position of the screw jack strut, at the top of the rack; a guide pillar is movably sleeved in the guide bracket; the top of the guide pillar is hinged to a pin insertion plate; the pin insertion plate is provided with a locking hole suitable for a positioning hole on a reel flange plate; a positioning pin is movably inserted in the locking hole. The gearless locking device for the hoist has the advantage that an original structure of locking a gear is changed into a mode of locking the flange plate of a reel device, so that the integral locking device has a more compact structure, a light weight and a small appearance size and is convenient to operate. When the reel device hoists a gate by a steel wire rope, the gearless locking device can enable the reel device to be positioned at a random position in the range of 360 degrees; locking of the gate in locally-open and full-open states is met; working efficiency of the complete machine is improved.
Description
Technical field
The utility model relates to water conservancy project plant equipment field, especially relates to a kind of headstock gear gearless locking device.
Background technology
Lifting appliance be with intermittently, the working method that repeats, by load-engaging device hoist, decline the to migrate equipment of material.Water conservancy project lifting appliance is ingredient important in water conservancy project machinery, and main form of structure is the headstock gear of open-close sluice gate.Development along with Hydraulic and Hydro-Power Engineering comprehensive utilization, status as the lifting appliance using in gate of hydropower station and trashrack, trash rake is also more and more outstanding, has also more and more applied to water conservancy lifting appliance---headstock gear simultaneously in the waterproof conveyance system of city.In order to meet the demand of the compact to design and civic landscape layout of equipment, headstock gear requires to adopt closed-type cylindrical gearing mode (do not adopt large and small gear drive and substitute with drum coupling) more, and the office of gate opens with standard-sized sheet and adopts locking device to realize.Because the current locking device great majority of water conservancy industry opening and closing device are to carry out lock gear with straight-tooth, not only appearance and size is large for this kind of locking device, and machining accuracy is high, and is unfavorable for the locking without gear wheel state tail gates.
Summary of the invention
The utility model object is for closed-type cylindrical gearing mode, and a kind of headstock gear gearless locking device that takes up room little, easy to operate is provided.
For achieving the above object, the utility model can be taked following technical proposals:
Headstock gear gearless locking device described in the utility model, comprises frame; At described frame inner bottom part, be provided with pallet, on described pallet, be provided with jackscrew, in the frame near jackscrew pole place, be provided with travel switch; At frame top and corresponding position, jackscrew pole position, be provided with vertically upward guiding trestle, in described guiding trestle, be movably installed with lead, described lead top is hinged with wears pin plate, described wear on pin plate, offer with reel flanged plate on the lock hole that adapts of locating hole, on described lock hole, activity is fitted with alignment pin.
The described pin plate of wearing is comprised of the Weight plate in left side and the junction plate on right side, and described lock hole separates the junction plate edge that is located at right side between the upper and lower.
Described frame bottom is provided with pulley and positioner.
The frame below corresponding with described pulley position is equipped with slide rail, and described positioner is the locating clamp plate being arranged on described slide rail.
The utility model advantage is original lock gear structure to change to the mode of locking roll device flanged plate, makes integral locking apparatus structure compacter, lightweight and appearance and size is little, easy to operate.By motor, by speed reducer with high transmission ratio, drive roll device, while lifting by crane gate by the reciprocating motion of wire rope, realizing roll device 360
0the location of optional position, the office that has met gate open with full-gear under locking, improved the operating efficiency of complete machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that Fig. 1 wears the left view after pin plate locking.
The specific embodiment
As shown in Figure 1, 2, headstock gear gearless locking device described in the utility model, comprises frame 1; At frame 1 inner bottom part, be provided with pallet 2, on pallet 2, be provided with jackscrew 3, in the frame 1 near jackscrew pole place, be provided with travel switch 4; At frame 1 top and corresponding position, jackscrew pole position, be provided with vertically upward guiding trestle 5, in guiding trestle 5, be movably installed with lead 6, lead 6 tops are hinged with wears pin plate, wearing pin plate is comprised of the Weight plate 10 in left side and the junction plate 11 on right side, junction plate 11 edges on right side separate be between the upper and lower provided with reel flanged plate 7 on the lock hole that adapts of locating hole 8, on lock hole, activity is fitted with alignment pin 9; In frame 1 bottom, be provided with pulley 12 and positioner, frame 1 below corresponding with pulley 12 positions is equipped with slide rail 13, and this positioner is the locating clamp plate 14 being arranged on slide rail 13.
Its operating principle is: when roll device need to lock, pulley 12 moves along slide rail 13, adjust the relative position of guiding trestle 5, on the lock hole of offering on adjusting to junction plate 11 and reel flanged plate 7 during locating hole 8 centering, by alignment pin 9, junction plate 11 is connected to location (the uniform locating hole of 360 degree on the edge of reel flanged plate 7) with reel flanged plate 7, jackscrew 3 pole jack-up leads 6 are by 7 lockings of reel flanged plate simultaneously, locating clamp plate 14 lifts, frame 1 is fixing, travel switch 4 sends signal simultaneously, headstock gear quits work, thereby reach the object of integral locking.
