Detailed Description
The present invention is described in detail below with reference to various embodiments, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should be able to make modifications and substitutions on the functions, methods, or structures of these embodiments without departing from the scope of the present invention.
As shown in fig. 1, 2 and 3, an embodiment of the present invention provides a lifting transmission device, which includes: a fixed pulley block 10, a movable pulley block 20, a transmission steel wire rope 30 and a power mechanism 40.
In the embodiment, the fixed pulley block 10 and the movable pulley block 20 are arranged, so that the number of steel wire ropes capable of being stressed is increased, and the elastic deformation of the steel wire ropes is effectively reduced.
Specifically, the crown block assembly 10 includes: a first fixed sheave 11, a second fixed sheave 12, a third fixed sheave 13, a fourth fixed sheave 14, and a fifth fixed sheave 15.
The first fixed pulley 11 and the second fixed pulley 12 are symmetrically arranged and can independently operate. The third fixed sheave 13 and the fourth fixed sheave 14 are disposed symmetrically left and right, and are disposed side by side with the first fixed sheave 11 and the second fixed sheave 12. Meanwhile, the third fixed sheave 13 and the fourth fixed sheave 14 can be independently operated. Further, the fifth fixed pulley 15 is located below the third fixed pulley 13 and the fourth fixed pulley 14.
Further, the movable pulley block 20 is located below the fifth fixed pulley 15, and includes: a first movable sheave 21 and a second movable sheave 22; the first movable sheave 21 and the second movable sheave 22 are collectively fitted over a wheel shaft. At this time, one end of the transmission wire rope 30 is pulled by the power mechanism 40, and the other end thereof passes around the first fixed pulley 11, the third fixed pulley 13, the first movable pulley 21, the fifth fixed pulley 15, the second movable pulley 22, the fourth fixed pulley 14, and the second fixed pulley 12 in this order. So set up, through addding a set of fixed pulley for the wire rope quantity that can atress increases, and then has reduced wire rope's elastic deformation effectively. Meanwhile, the fifth fixed pulley 15 in the fixed pulley group 10 can also play a role in dynamic balance, thereby being beneficial to avoiding elastic deformation of the steel wire rope.
The lifting transmission device further includes an auxiliary wire rope 50, the auxiliary wire rope 50 is connected in parallel with the transmission wire rope 30 which is wound around the fifth fixed pulley 15, and the auxiliary wire rope 50 is wound around the pressing block 70 which is positioned above the fifth fixed pulley 15. So when making around the wire rope fracture of fifth fixed pulley 15, the goods that hoist can take place to fall, and then has increased the security of goods lifting operation.
Specifically, the auxiliary wire rope 50 is connected in parallel to the transmission wire rope 30 that passes around the fifth fixed sheave 15, and the auxiliary wire rope 50 passes around the pressing block 70 located above the fifth fixed sheave 15. Thus, when the steel wire rope around the fifth fixed pulley 15 is broken, the auxiliary steel wire rope 50 is in a tensioning state and is pressed on the pressing block 70, and then the hoisted goods are continuously pulled, so that the goods cannot fall off, and the safety of goods hoisting operation is improved.
In one embodiment, both ends of the auxiliary rope 50 are connected in parallel to the driving rope 30 wound around the fifth fixed sheave 15 by the rope clamps 60. Preferably, either end of the auxiliary rope 50 is connected to the corresponding position of the driving rope 30 by two rope clamps 60.
Wherein, the wire rope clamp 60 includes: a rope clamp seat 61 and a U-shaped pressure rod 62.
The rope holder 61 has two rope grooves arranged side by side, and the transmission steel wire rope 30 and the auxiliary steel wire rope 50 are respectively accommodated in the corresponding rope grooves and are pressed and fixed by a U-shaped press rod 62 with two ends connected to the rope holder 61. In order to connect the U-shaped pressing rod 62 with the rope clamp seat 61, external threads are arranged at two ends of the U-shaped pressing rod 62, so that the U-shaped pressing rod 62 can be connected with the rope clamp seat 61 in a threaded manner.
In addition, in order to keep the auxiliary wire rope 50 attached to the pressing block 70 at all times, the auxiliary wire rope 50 is also connected to the pressing block 70 through at least one fixing block 80. At this time, the fixing block 80 has a rope groove for accommodating the auxiliary steel wire rope 50, and both ends of the fixing block 80 are connected to the pressing block 70 by bolts.
The lifting transmission device further comprises a rope breakage detection switch 90 which can detect whether the steel wire rope is broken or not in real time so as to give an alarm in time. Specifically, the rope breakage detecting switch 90 has a roller contact, and the roller contact abuts against the transmission wire rope 30 that is wound around the fifth fixed pulley 15. Thus, the roller contact can synchronously roll along with the contacted transmission steel wire rope 30. And the rope breakage detection switch 90 can send out an alarm signal when the roller contact is separated from the transmission steel wire rope 30 against which the roller contact abuts. Therefore, when the transmission steel wire rope 30 is broken, the roller contact is separated from the transmission steel wire rope, and then the roller contact performs certain actions. At this time, the rope breakage detecting switch 90 is set to emit an alarm signal in accordance with the action of the roller contact.
The power mechanism 40 is used for driving the movable pulley block 20 to move through the transmission steel wire rope 30, and further driving the goods to lift. The power mechanism 40 includes: a sheave 41, a speed reducer 42, and a motor 43. The motor 43 is in transmission connection with the rope wheel 41 through the speed reducer 42, and the rope wheel 41 is provided with a rope groove suitable for winding the transmission steel wire rope 30.
As shown in fig. 4, another embodiment of the present invention further provides a stacker crane, including: a mast 100 and a lift actuator 200 as described above, the lift actuator 200 being integrated into the mast 100.
In summary, in the lifting transmission device of the present invention, the fixed pulley block and the movable pulley block are arranged, so that the number of steel wire ropes capable of being stressed is increased, and the elastic deformation of the steel wire ropes is effectively reduced. Meanwhile, the fifth fixed pulley in the fixed pulley group can also play a role in dynamic balance, and further the elastic deformation of the steel wire rope can be avoided. The auxiliary steel wire rope is additionally arranged on the lifting transmission device, so that when the steel wire rope which bypasses the fifth fixed pulley is broken, the lifted goods can fall, and the safety of goods lifting operation is improved. The lifting transmission device is also provided with a rope breakage detection switch, and can detect whether the steel wire rope is broken in real time so as to alarm in time.
