Abstract
The utility model relates to a hand-power elevating mechanism, in particular to a hand-power elevating mechanism that is associated to the electric elevating mechanism, which comprises a hand-pull chain, a hand-pull chain wheel, a motor axle and a lower cover; wherein, the hand-pull chain wheel is engaged with the hand-pull chain, the hand-pull chain wheel is fixed through the lower cover and the motor axle, the chain-wheel clutch-block base is fixed on a chain-wheel connecting plate, the trolley rack is contacted the micro-active switch, a cylinder pressure spring is positioned between the chain-wheel clutch block and the chain-wheel clutch-block base; the trolley is positioned on a rotating axle, and the rotating axle is arranged in the groove of the rotating-axle rack. The utility model has the advantages of that the transformation of the electric power and manual power is realized through the micro-active switch without the elements such as the clutch; adopting of the trolley, rotating axle and the roller rack is able to make the hand-power elevating mechanism be positioned on the horizontal direction and the vertical direction without influencing the application of the hand-pull chain; application of the hand-pull chain is able to drive the motor axle that is engaged with the chain-wheel clutch block through the hand-pull chain wheel, chain-wheel clutch-block base and the chain-wheel clutch block so as to realize the hand-power elevating function. Therefore, the utility model is much more convenient and reliable to mount and utilize, which has a promising application prospect.
Description
Technical field
The utility model relates to a kind of hoisting mechanism that pulls, particularly relate to a kind of be associated with electric hoisting mechanism pull hoisting mechanism.
Background technology
At present, existing industrial upgrading door pull hoisting mechanism because the critical piece upper rminal disc is made by nylon material, in current use, shortcoming to some extent on intensity, more obvious when northern area uses winter especially.In addition, original hoisting mechanism that pulls can only level be installed, and makes the use that pulls hoisting mechanism be subjected to bigger restriction.
Summary of the invention
In view of above problem, the purpose of this utility model is: provide a kind of that effectively address the above problem be associated with electric hoisting mechanism pull hoisting mechanism.
In order to reach above purpose, the utility model has adopted following technical scheme: it comprises and pulls chain, pulls chain sprocket wheel, motor shaft, lower cover, pull the chain sprocket wheel and pull the chain engagement, pulling the chain sprocket wheel fixes by lower cover and motor shaft, sprocket wheel clutch block is fixed on the sprocket wheel gusset piece, turning rolls contacts with microswitch, and cylindrical compression spring is between sprocket wheel clutch block and sprocket wheel clutch block; Roller is installed in the rotating shaft, and rotating shaft is installed in the groove of rotating shaft frame.
The utility model has the advantages that by microswitch realize electronic with manually between need not parts such as clutch and change; Utilize roller, rotating shaft and turning rolls to realize to make to pull hoisting mechanism can not influence the use that pulls chain in the arrangement of level and vertical direction; And utilize and to pull chain by pulling chain sprocket wheel and sprocket wheel clutch block, sprocket wheel clutch block, drive the motor shaft with the engagement of sprocket wheel clutch block, realize pulling enhanced feature.Therefore, the utility model is installed and used convenient reliable, and prospect is widely used.
Description of drawings
As shown in Figure 1, be main-vision surface structural representation of the present utility model;
As Fig. 2 institute, be not A-A face view of the present utility model.
The specific embodiment
The utility model mainly comprises: bearing (1), roller shaft (2), rotating shaft (3,5), rotating shaft frame (4), roller (6), pull chain (7), sprocket wheel gusset piece (8), sprocket wheel setting-up piece (9), lower cover (10), pull chain sprocket wheel (11), sprocket wheel clutch block (12), sprocket wheel clutch block (13), cylindrical compression spring (14), motor shaft (15), bearing (16), microswitch (17), microswitch support (18), turning rolls (19).
As shown in the figure, pull chain sprocket wheel (11) and pull chain (7) engagement, it is fixing by lower cover (10) and motor shaft (15) to pull chain sprocket wheel (11), sprocket wheel clutch block (12) is fixed on the sprocket wheel gusset piece (8), turning rolls (19) contacts with microswitch (17), and cylindrical compression spring (14) is positioned between sprocket wheel clutch block (13) and the sprocket wheel clutch block (12).
During work, pulling pulls chain (7), moves in the groove on rotating shaft frame (4) in rolling in the rotating shaft (5) and rotating shaft (5) by roller (6), can make pull hoisting mechanism pull the pulling of chain (7) horizontal direction or vertical direction; And by roller (6), rotating shaft frame (4) and rotating shaft (5), turning rolls (19) and microswitch (17) are disengaged, by the microswitch deenergization, realize the electronic interlocking between the mechanism when manual switch, simultaneously by being fixed on the bearing (1) on the turning rolls (19), sprocket wheel clutch block (13) is pressed to sprocket wheel clutch block (12), the stressed contraction of cylindrical compression spring (14) between sprocket wheel clutch block (13) and the sprocket wheel clutch block (12), sprocket wheel clutch block (13) inner ring spline and motor shaft (15) engagement, this moment, output torque was by pulling chain (7), pull chain sprocket wheel (11), sprocket wheel clutch block (12), bearing (16) and sprocket wheel clutch block (13) are passed to motor shaft (15), thereby realize pulling enhanced feature.
When stopping to pull, because pressure is removed, cylindrical compression spring (14) will restore to the original state, make sprocket wheel clutch block (13) and motor shaft (15) break away from engagement, make turning rolls (19) contact microswitch (17) simultaneously, microswitch (17) closure, by the power supply power supply, realize manually to electronic conversion.
Claims (1)
1, a kind of hoisting mechanism that pulls, it comprises and pulls chain, pulls chain sprocket wheel, motor shaft, lower cover, it is characterized in that: pull chain sprocket wheel (11) and pull chain (7) engagement, it is fixing by lower cover (10) and motor shaft (15) to pull chain sprocket wheel (11), sprocket wheel clutch block (12) is fixed on the sprocket wheel gusset piece (8), turning rolls (19) contacts with microswitch (17), and cylindrical compression spring (14) is positioned between sprocket wheel clutch block (13) and the sprocket wheel clutch block (12); Roller (6) is installed in the rotating shaft (5), and rotating shaft (5) is installed in the groove of rotating shaft frame (4).
