Detailed Description
Embodiment 1 As shown in fig. 1-4, the fixed winch hoist with the balance beam comprises a winch bracket, a winding drum set, a lifting hook, a balance beam device and the like, wherein the lifting hook is provided with a first movable pulley and a second movable pulley.
In this example, the winding drum set is mounted on the hoist bracket, and the winding drum set includes a first winding drum and a second winding drum, where the first winding drum and the second winding drum are coaxially connected.
The balance beam device in the embodiment comprises a balance beam and a supporting plate 9 which are arranged in parallel, wherein the middle part of the balance beam is connected with the middle part of the supporting plate 9 through a bracket 6, and the middle part of the supporting plate 9 is supported on a winch bracket through a fulcrum mechanism. When the balance beam device is in an initial balance state, the balance beam on the balance beam device is parallel to the axis of the winding drum group.
In this example, the length of the balance beam is adapted to the length of the axis direction of the winding drum set, the balance beam is provided with a first rope guiding mechanism 71 and a second rope guiding mechanism 72, and the first rope guiding mechanism 71 and the second rope guiding mechanism 72 are respectively located at two sides of the bracket 6 and respectively arranged on the balance beam in a way that the locking sleeve 3 can move back and forth along the axis of the balance beam.
The first rope guiding mechanism 71 in this example has a first guiding channel in which two parallel rollers 12 are arranged, the first wire rope 10 passing through the guiding channel from the area between the two rollers 12, and the second rope guiding mechanism 72 has a second guiding channel in which two parallel rollers 12 are arranged, the second wire rope 11 passing through the guiding channel from the area between the two rollers 12.
In this embodiment, a driving mechanism for driving the first rope guide 71 and the second rope guide 72 is provided corresponding to the first rope guide 71 and the second rope guide 72, and the driving mechanism adapts the movement of the first rope guide 71 to the movement of the first wire rope 10 in the first reel axis direction (the movement speed and the movement direction are adapted, for example, the wire rope moves d in the reel axis direction when the wire rope winds around the reel from the left end to the right end of the reel, and simultaneously the first rope guide 71 moves d from left to right), and adapts the movement of the second rope guide 72 to the movement of the second wire rope 11 in the second reel axis direction.
The embodiment comprises an external power mechanism 8, a transmission shaft 1 and two guide shafts 2, wherein the two guide shafts 2 are parts of a balance beam and are arranged in parallel with the length direction of the balance beam, the transmission shaft 1 is parallel to the guide shafts 2, the transmission shaft 1 is provided with left and right external threads, the left and right external threads are opposite and symmetrical, the transmission shaft is connected with the external power mechanism 8, and the transmission shaft is driven by the external power mechanism 8 to rotate around the axis thereof.
In this example, the first rope guiding mechanism 71 and the second rope guiding mechanism 72 are respectively installed on the guiding shaft 2 and the transmission shaft 1 through a locking sleeve 3, and the locking sleeve 3 is provided with guiding holes matched with the two guiding shafts 2 and threaded holes matched with external threads on the transmission shaft 1. The left external thread and the right external thread on the transmission shaft 1 are opposite and symmetrical, so that the motion of the rope guiding mechanisms at the two sides is symmetrical.
In this embodiment, two ends of the pallet 9 in the length direction are respectively provided with a wire rope locking device 5 through a special-shaped pulley mechanism 4. Because the special-shaped pulley is not a simple balance beam device, the structure of the special-shaped pulley is a fan-shaped structure, and the factors such as uniform stress of the round pulley and balance action of the rod balance beam are combined, the pulley rotation angle is larger, so that the problem that the amplitude range of uneven stress caused by different lengths of steel wire ropes on two sides is larger can be adjusted.
In this example, a first wire rope 10 is provided corresponding to a first reel, one end of the first wire rope is fixed on a wire rope locking device 5 at one end of the balance beam device, the other end of the first wire rope passes through a first movable pulley and a first rope guiding mechanism 71 and then is fixed on the first reel, a second wire rope 11 is provided corresponding to a second reel, one end of the second wire rope is fixed on the wire rope locking device 5 at the other end of the balance beam device, and the other end of the second wire rope passes through a second movable pulley and a second rope guiding mechanism 72 and then is fixed on the second reel.
According to the embodiment, the external power mechanism 8 drives the rope guiding mechanisms on two sides to move along the length direction of the balance beam through the transmission shaft 1, so that the positions of the rope guiding mechanisms and corresponding steel wire ropes on corresponding reels are basically corresponding, the steel wire ropes can be wound on the reels better, the rope skipping angle of the steel wire ropes is ensured to be more reasonable, and good winding can be realized.

Embodiment 2 this embodiment is substantially identical to embodiment 1 except that in this embodiment the hooks comprise a first hook having a first movable pulley and a second hook having a second movable pulley.
