[0027] The beneficial effect of the present invention is that the present invention can replace the traditional single steel wire rope with two steel wire ropes for fixed force transmission by setting a balance beam device. The setting of the two steel wire ropes greatly reduces the difficulty of wire rope threading and balancing.

[0028] The balance beam is a basic structure in mechanical manufacturing, which is used to solve the problems of balance and support in mechanical systems. The present invention provides a new balance structure for the fixed winch hoist of the steel gate of the water conservancy and hydropower project. The balance beam can disperse the load in the mechanical system, making the load more uniform, and reducing the situation where some parts are damaged by excessive load alone. It is used to replace the traditional balance pulley device, and improves the shortcomings of the traditional balance beam, such as single-point adjustment, inability to change the angle of the wire rope, and easy friction between the wire rope and the structural parts.

[0029] The rope guide mechanism on the balance beam device of the present invention is adapted to the movement of the wire rope in the axial direction of the drum, so that the angle at which the wire rope enters the drum and the fixed pulley can be maintained at an optimal level, and the number of rope winding layers of the wire rope can be greatly increased, so as to increase the pulley ratio and reduce the single-wire tension of the wire rope.

[0030] A special-shaped pulley is used in the rope locking mechanism of the balance beam in the present invention. The fan-shaped structure of the pulley is designed to ensure the uniformity of the force on its structural parts under different heavy-load conditions, ensuring that the force strength of its balance structural parts is not reduced under the heavy-load adjustment state. Generally, when the balance beam is tilted to a certain angle, the vertical force strength of its rods will be greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Example 1: Figure 1 to Figure 4As shown, the fixed winch type gate hoist with a balance beam in this embodiment includes a winch bracket, a drum assembly, a hook and a balance beam device, wherein the hook has a first movable pulley and a second movable pulley.

[0037] In this example, the drum assembly is installed on the winch bracket, and the drum assembly includes a first drum and a second drum, and the first drum and the second drum are coaxially connected.

[0038] In this embodiment, the balance beam device includes a balance beam and a support plate 9 arranged in parallel with each other, wherein the middle of the balance beam is connected to the middle of the support plate 9 via a bracket 6, and the middle of the support plate 9 is supported on the winch bracket via a fulcrum mechanism. When the balance beam device is in an initial balanced state, the balance beam thereon is parallel to the axis of the drum group.

[0039] In this example, the length of the balance beam is matched with the axial length of the reel group, and the balance beam is equipped with a first guide rope mechanism 71 and a second guide rope mechanism 72. The first guide rope mechanism 71 and the second guide rope mechanism 72 are respectively located on both sides of the bracket 6 and are respectively installed on the balance beam so as to be movable back and forth along the axis of the balance beam through the locking sleeve 3.

[0040] In this example, the first guide rope mechanism 71 has a first guide channel, in which two rollers 12 are parallel to each other, and the first steel wire rope 10 passes through the guide channel from the area between the two rollers 12; the second guide rope mechanism 72 has a second guide channel, in which two rollers 12 are parallel to each other, and the second steel wire rope 11 passes through the guide channel from the area between the two rollers 12.

[0041] In this embodiment, a driving mechanism for driving the first guide rope mechanism 71 and the second guide rope mechanism 72 to move is provided corresponding to the first guide rope mechanism 71 and the second guide rope mechanism 72, and the driving mechanism makes the movement of the first guide rope mechanism 71 adapt to the movement of the first steel wire rope 10 in the axial direction of the first drum (the moving speed and the moving direction are adapted, such as when the steel wire rope moves d in the axial direction of the drum when it wraps around the drum from the left end to the right end of the drum, and at the same time, the first guide rope mechanism 71 moves d from left to right), so that the movement of the second guide rope mechanism 72 adapts to the movement of the second steel wire rope 11 in the axial direction of the second drum.

[0042] The present embodiment includes 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 parallel to the length direction of the balance beam, the transmission shaft 1 is parallel to the guide shaft 2, and the transmission shaft 1 is provided with left and right sections of external threads, the left and right sections of external threads are opposite and symmetrical, the transmission shaft is connected to the external power mechanism 8, and the transmission shaft is driven by the external power mechanism 8 to rotate around its axis.

[0043] In this example, the first guide rope mechanism 71 and the second guide rope mechanism 72 are respectively installed on the guide shaft 2 and the transmission shaft 1 through a locking sleeve 3, and the locking sleeve 3 is provided with guide holes adapted to the two guide shafts 2 and threaded holes adapted to the external threads on the transmission shaft 1. Since the left and right sections of the external threads on the transmission shaft 1 are opposite and symmetrical, the movement of the guide rope mechanisms on both sides is symmetrical.

[0044] In this embodiment, wire rope lockers 5 are installed at both ends of the support plate 9 in the length direction through the special-shaped pulley mechanism 4. Since the special-shaped pulley is not a simple balance beam device, its structure is a fan-shaped structure, which combines the uniform force of the circular pulley and the balancing effect of the rod balance beam. The pulley has a large rotation angle, so that the problem of uneven force caused by the different lengths of the wire ropes on both sides can be adjusted.

[0045] In this example, a first steel wire rope 10 is provided corresponding to the first drum, one end of the first steel wire rope is fixed to the steel wire rope locker 5 at one end of the balance beam device, and the other end of the first steel wire rope is fixed to the first drum after passing through the first movable pulley and the first rope guide mechanism 71; a second steel wire rope 11 is provided corresponding to the second drum, one end of the second steel wire rope is fixed to the steel wire rope locker 5 at the other end of the balance beam device, and the other end of the second steel wire rope is fixed to the second drum after passing through the second movable pulley and the second rope guide mechanism 72.

[0046] In this embodiment, the external power mechanism 8 drives the rope guide mechanisms on both sides to move along the length direction of the balance beam via the transmission shaft 1, so that the positions of the rope guide mechanisms and the corresponding steel wire ropes on the corresponding drums basically correspond to each other, so as to better wind the steel wire ropes around the drums, ensure that the rope skipping angle of the steel wire ropes is more reasonable, and can be well wound.

[0047] In this example, the external power mechanism 8 can be a motor, which is equipped with a control unit for controlling its rotation speed and direction. The control unit determines the rotation speed and direction of the motor based on preset control rules combined with the speed and angle of the reel rotation.

[0048] Embodiment 2: The structure of this embodiment is basically the same as that of Embodiment 1, and the only difference is that the hook in this embodiment includes a first hook and a second hook, wherein the first hook has a first movable pulley, and the second hook has a second movable pulley.
