Description
Technical field
The utility model belongs to vehicle for construction technical field, relates to a kind of rotary-vane pump type automatic oiling machine of building hoist.
Background technology
Elevator is conventional construction machinery equipment, because environment for use is severe, often needs to carry out general maintenance to key position charging-up lubricant oils such as lifter racks, up and down guide cylinder face.Charging-up lubricant oil is stained with to choose after a lubricating oil descendant arrives filling-up area by lifting climbing from oil drum by artificial club to smear in the past, and current general-purpose construction elevator has eight filling-up areas usually.Because eight filling-up areas often will refuel, by artificial climbing, there is potential safety hazard in aerial work; Artificial rod is coated with rod and smears that efficiency is low, labour intensity is large; By oil mass entirely with feeling, smearing inequality, club be stained with the lubricating oil people that provokes also no climbing to filling-up area just likely partial exfoliation, or filling-up area is due to the too many thus partial exfoliation of applying amount, cause waste, the oiling mode adopting this tradition to fall behind, about has the lubricating oil of 50% to waste because coming off.
Therefore, people have invented automatic oil injection machine of construction elevator, such as: publication number is CN201120183615.4, disclose a kind of automatic oil injection machine of construction elevator, comprise the pump housing, motor in the Chinese patent of " automatic oil injection machine of construction elevator " by name; The pump housing is provided with oil inlet and oil outlet; Motor is in transmission connection by eccentric wheel and the endoceliac movable part of pump by bent axle by retarder.
The endoceliac movable part of its pump is piston.
Its principle of work is: driven by motor retarder, retarder is in transmission connection eccentric wheel, eccentric wheel band dynamic crankshaft pumps, and bent axle is driven reciprocating motion of the pistons by eccentric wheel thus is transported to filling-up area from oil outlet after being pressurizeed by the pump housing by the lubricating oil entered from oil inlet.
Adopt the automatic oil injection machine of construction elevator of such technology certainly can realize charging-up lubricant oil, but be the drawing-in type structure that eccentric wheel band dynamic crankshaft drives the piston up-down in pumping cylinder due to what adopt, transmission link many structures relative complex, manufacturing cost are relatively high, action is steady not, reliability is high not enough, and result of use is desirable not enough.
Utility model content
For overcoming the deficiencies in the prior art, the utility model provides that a kind of structure is relatively simpler, manufacturing cost is relatively lower, stable action reliability is higher, the rotary-vane pump type automatic oiling machine of result of use more preferably building hoist.
The utility model for the technical scheme reaching above-mentioned technical purpose and adopt is: a kind of rotary-vane pump type automatic oiling machine of building hoist, comprises the pump housing, motor; The pump housing is provided with the oil inlet and oil outlet that are communicated with pump housing inner chamber; Motor is in transmission connection by retarder and the endoceliac movable part of pump; The inner chamber of the pump housing is columniform cavity; The endoceliac movable part of pump is columniform rotor; The length of rotor is equal with the columniform length of cavity; The diameter of rotor is less than the diameter of cavity; The axis of rotor and the axis parallel of cavity; Rotor is eccentric setting in cavity; Two opposite positions on the side face of rotor be axially arranged with the square straight groove equal with the length of rotor, box-shaped blade is all movably set with in two grooves, the bottom surface of two blades is provided with spring installation, and the end face of two blades is pressed against with the internal face activity of the inner chamber of the pump housing and is connected.
Described box-shaped blade is first blade and second blade; Be provided with stage clip in rotor block between the corresponding bottom surface of first blade and second blade, the both ends of the surface of stage clip lean connection with the corresponding bottom surface of first blade and second blade respectively.
The both ends of the surface of the inner chamber of the described pump housing are equipped with rounded seal.
The beneficial effects of the utility model are: the inner chamber due to the pump housing is columniform cavity; The endoceliac movable part of pump is columniform rotor; The length of rotor is equal with the columniform length of cavity; The diameter of rotor is less than the diameter of cavity; The axis of rotor and the axis parallel of cavity; Rotor is eccentric setting in cavity; Two opposite positions on the side face of rotor be axially arranged with the square straight groove equal with the length of rotor, box-shaped blade is all movably set with in two grooves, the bottom surface of two blades is provided with spring installation, and the end face of two blades is pressed against with the internal face activity of the inner chamber of the pump housing and is connected.
Because motor only has rotary motion by the whole transmission process of retarder and rotor, transmission link is few, and structure is relatively simpler, manufacturing cost is relatively lower, stable action reliability is higher, and result of use is better.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.Wherein:
Fig. 1 is schematic diagram of the present utility model.
Marker number in accompanying drawing is described as follows: oil inlet 1, first blade 2, the pump housing 3, rotor 4, first cavity 5, second blade 6, second cavity 7, stage clip 8, oil outlet 9
Detailed description of the invention
Embodiment of the present utility model, as shown in Figure 1, a kind of rotary-vane pump type automatic oiling machine of building hoist, comprises the pump housing 3, motor; The pump housing 3 is provided with the oil inlet 1 and oil outlet 9 that are communicated with the pump housing 3 inner chamber; Motor is in transmission connection by the movable part in retarder and the pump housing 3 chamber; The inner chamber of the pump housing 3 is columniform cavitys; Movable part in the pump housing 3 chamber is columniform rotor 4; The length of rotor 4 is equal with the columniform length of cavity; The diameter of rotor 4 is less than the diameter of cavity; The axis of rotor 4 and the axis parallel of cavity; Rotor 4 eccentric setting in cavity; Two opposite positions on the side face of rotor 4 be axially arranged with the square straight groove equal with the length of rotor 4, box-shaped blade is all movably set with in two grooves, the bottom surface of two blades is provided with spring installation, and the end face of two blades is pressed against with the internal face activity of the inner chamber of the pump housing 3 and is connected.
