TECHNICAL FIELD
[0001] The utility model relates to construction hoist especially intelligent construction hoist double -open door drive mechanism. BACKGROUND
[0002] The construction hoist cage feed door is single -open door, and the discharge door is double -open door, the upper part is the middle door, and the lower part is the small door. The ordinary construction hoist cage double -open door adopts the steel wire rope to connect the middle door and the small door, when the double -open door opens, the driver pushes the middle door upwards, makes the middle door run upwards, the steel wire rope links the small door and runs downwards, under the inertial action until the small door connecting plate touches the lower limit block and stops running. When the double -open door closes, the driver pulls the middle door downwards, makes the middle door run downwards, the steel wire rope links the small door and runs upwards, under the inertial action until the middle door and the small door touch and stop running. This kind of manual door opening mode has certain security risks, and the door opening effect is often not ideal. SUMMARY
[0003] The utility model provides a kind of intelligent construction hoist double -open door drive mechanism, can realize automatic open / close door, reduce security risks, improve the stability of open / close door.
[0004] To solve the above technical problems, the technical scheme of the utility model is: a kind of intelligent construction hoist double -open door drive mechanism, including middle door and the small door located in the lower part of middle door, further including chain in the side of cage, one end of the chain is connected with middle door, the other end of the chain is sequentially wound over sprocket, downward guide wheel, vertically downwards and is connected with adjusting rod, the small door is connected with connecting plate, nut is equipped on the connecting plate, the adjusting rod is connected with nut by screw thread, the top of the cage is equipped with motor connected with sprocket. The utility model principle: when intelligent construction hoist double -open door opens, motor drives sprocket rotation, drives chain movement, chain pulls middle door and runs upwards, while small door runs downwards under the action of gravity, until double -open door limit switch action, motor stops, and door opening is completed;Similarly, when intelligent construction hoist double -open door closes, motor reverses and drives chain, chain pulls small door and runs upwards, while middle door runs downwards under the action of gravity, until double -open door limit switch action, motor stops, and door closing is completed. One end of chain is connected with small door by the cooperation of adjusting rod and nut, and the tightness of chain can be adjusted by rotating adjusting rod.
[0005] As an improvement, the side of the cage is provided with a chain cover covering the chain.
[0006] As an improvement, the upper end of the chain cover is provided with a cover plate.
[0007] As an improvement, the chain cover is fixed on the cage by bolts.
[0008] As an improvement, the cage cover is a sheet metal part with multiple bends.
[0009] As an improvement, the outer side of the guide wheel is provided with a baffle.
[0010] As an improvement, the connecting plate is sleeved on the door frame of the cage, the front end of the connecting plate is connected with the upper end of the small door, and the rear end of the connecting plate is connected with the adjusting rod through a nut.
[0011] The utility model compared with prior art brings beneficial effect is:
[0012] The crane drives the middle door and the small door through the chain arranged on the side surface of the cage, realizes the automatic opening / closing door of the double-opening door, reduces the security risk, and improves the stability of the opening / closing door. BRIEF DESCRIPTION OF DRAWINGS
[0013] Figure 1 It is the schematic diagram I of cage.
[0014] Figure 2 It is the schematic diagram II of cage.
[0015] Figure 3 It is Figure 1 the enlarged view of A.
[0016] Figure 4 It is the schematic diagram of drive assembly.
[0017] Figure 5 It is the schematic diagram of chain cover. DETAILED DESCRIPTION
[0018] The utility model will be further explained in connection with the drawings of specification.
[0019] As Figure 1 , 2 shown, a kind of intelligent construction hoist double-opening door drive mechanism, including middle door 12, small door 13 located below middle door 12 and drive assembly, drive assembly drives middle door 12 and small door 13 reverse motion realizes the action of opening / closing door.
[0020] As Figures 1 to 5As shown, the driving assembly comprises a chain 4 arranged at the side of the cage 1 close to the door opening and a motor 9 arranged at the top of the cage 1; one end of the chain 4 is connected with the upper end of the middle door 12, the other end of the chain 4 is sequentially wound upwards around the sprocket 2, downwards around the guide wheel 3, and vertically downwards connected with the adjusting rod 7; the cage 1 door frame is sleeved with a connecting plate 6, the connecting plate 6 can run up and down along the door frame; the upper end of the small door 13 is connected with the front end of the connecting plate 6, the rear end of the connecting plate 6 is provided with a nut 8, the adjusting rod 7 is threadedly connected with the nut 8, the chain 4 can not only drive the small door 13 through the adjusting rod 7, the nut 8 and the connecting plate 6, but also adjust the tightness of the chain 4 by rotating the adjusting rod 7. The motor 9 drives the chains 4 on both sides through a transmission mechanism 10. The outer side of the guide wheel 3 is provided with a baffle to prevent the chain 4 from jumping off the guide wheel 3. The side of the cage 1 is provided with a chain cover 11 covering the chain 4, the chain cover 11 is fixed on the cage 1 through bolts, the upper end of the chain cover 11 is provided with a cover plate, and the cage 1 cover is a sheet metal part with multiple bends; the chain cover 11 not only has a better appearance, but also can effectively prevent falling objects from damaging the chain 4, the sprocket 2 and the guide wheel 3, etc., protect the normal operation of the double doors, and avoid danger.
[0021] The utility model principle: when the intelligent construction hoist double door opens, the motor 9 drives the sprocket 2 to rotate, drives the chain 4 to move, the chain 4 pulls the middle door 12 to run upwards, and the small door 13 runs downwards under the action of gravity simultaneously, until the double door limit switch acts, the motor 9 stops, and the opening is completed; similarly, when the intelligent construction hoist double door closes, the motor 9 reverses to drive the chain 4, the chain 4 pulls the small door 13 to run upwards, and the middle door 12 runs downwards under the action of gravity simultaneously, until the double door limit switch acts, the motor 9 stops, and the closing is completed.
