[0004] When gate is obliquely arranged, and needs to be overhauled, multiple pull rods need to be assembled on site and cooperate with gate machine or winch arranged on dam for hoisting, which is large in workload and low in work efficiency, and during hoisting process, gate cannot move parallel to gate slot, hoisting steel wire rope will interfere with gate slot, gate will be blocked or steel wire rope will be severely worn, which can easily cause operation failure and safety problem. Especially when hoisting lift is large, the center of gravity of vertical hoisting winch is high, and it is more likely to be unstable and fall, which can cause serious threat to surrounding personnel and equipment.

[0005] Therefore, conventional vertical hoisting winch is usually only applicable to specific vertical hoisting operation scene, and its applicability is greatly limited for operation requiring horizontal movement of heavy object or multi-angle hoisting. In actual engineering, many hoisting tasks often need to combine multiple hoisting modes, which makes vertical hoisting winch unable to meet actual demand in many cases. UTILITY MODEL CONTENTS

[0021] As Figure 2 shown, drive mechanism includes motor 3, the output of motor 3 is connected with the high-speed shaft of speed reducer 4 by shaft coupling, and the low-speed shaft of speed reducer 4 is the output of the drive mechanism.The components included in drive mechanism can be increased or reduced according to actual needs, expand the applicable scene of the utility model inclined hoisting winch.

[0022] Reel 2 is axially divided into first winding area and second winding area, and the both ends of steel wire rope 1 are wound in first winding area and second winding area respectively.Winding the both ends of steel wire rope 1 in area can prevent the both ends of steel wire rope 1 from being entangled with each other when tightening or loosening rotation, causing safety problems.

[0023] Balance mechanism 5 is a balance pulley block, and the axis of the pulley in the balance pulley block is perpendicular to the axis of reel 2.Steel wire rope 1 is wound around the balance pulley block, and when the both ends of steel wire rope 1 are unevenly stressed due to the tightening or loosening of reel 2, the length of the both ends of steel wire rope 1 can be adjusted by the rotation of the pulley itself, balancing the stress on the both ends of steel wire rope 1.

[0024] Hoisting mechanism 6 is a movable pulley block, which can make the hoisting action of steel wire rope 1 more smooth and not prone to jamming.The lower end of movable pulley block is fixed with a lifting hook, which can hook the lifting ring fixedly installed on the upper end of the gate, or the lower end of movable pulley block is directly hinged to the upper end of the gate to be hoisted, to improve the safety of the entire lifting operation process.

[0025] The working principle of the utility model inclined hoisting winch is as follows:

[0026] As Figure 3 shown, the utility model inclined hoisting winch is fixedly installed on the base platform built above the dam body during use.Rack 7 is a frame structure for supporting the drive mechanism and hinged balance mechanism of the winch, and the drive mechanism is the power input of the entire winch, which controls and drives the rotation of reel 2 and retracts and releases steel wire rope 1.

[0027] When the inclined setting dam gate needs to be lifted, the motor 3 of the driving mechanism is started, the speed is adjusted through the reducer 4, the drum 2 is driven to rotate, at this time, the two ends of the steel wire rope 1 on the two winding areas rotate at the same speed and are tightened, due to the pulling of the steel wire rope 1, the balance mechanism hinged at the lower end of the rack 7 is tilted, the lifting mechanism movably connected to the upper end of the gate is also tilted, so that the inclination angle of the steel wire rope 1 is consistent with the gate, and the force on the two ends of the steel wire rope 1 is balanced through the rotation of the balance pulley set. With the pulling of the steel wire rope 1, the gate is lifted along the inclined direction, avoiding the mutual interference of the steel wire rope 1 and the gate slot.

[0028] When the gate is completely lifted out of the gate slot, the gate, the balance mechanism and the lifting mechanism are restored to the vertical state.

[0029] Embodiment 1

[0030] The inclined lifting winch in this embodiment includes a rack 7 and a driving mechanism fixed on the upper surface of the rack 7, the output end of the driving mechanism is coaxially connected with a drum 2, the lower end of the rack 7 is hinged with a balance mechanism 5, a steel wire rope 1 is wound on the drum 2, the steel wire rope 1 passes through a lifting mechanism 6 suspended below the rack 7 and the balance mechanism 5 in turn, and then passes through the lifting mechanism 6 again, and returns to be wound on the drum 2, the two ends of the steel wire rope 1 are fixed on the drum 2.

[0031] The driving mechanism is the power source of the inclined lifting winch, which converts electrical energy, chemical energy or hydraulic energy into mechanical energy through devices such as motors, internal combustion engines or hydraulic motors to provide power for the rotation of the drum 2. The drum 2 is driven by the driving mechanism to lift or lower the weight by winding or releasing the steel wire rope. The driving mechanism generates a traction force large enough to meet the lifting needs of different weights.

[0032] The driving mechanism can adjust the rotation speed of the drum 2 of the winch, so as to control the lifting or lowering speed of the weight. By adjusting the output power or rotation speed of the driving mechanism, different speed lifting operations can be realized to meet the requirements of different working conditions.

[0033] The driving mechanism can control the forward and reverse rotation of the drum 2 of the winch, so as to realize the lifting and lowering of the weight. By changing the direction of the driving mechanism, the drum can rotate clockwise or counterclockwise to realize the winding or releasing of the steel wire rope 1.

[0034] When selecting the steel wire rope, according to the weight of the hoisted object, the hoisting method and other factors, the minimum breaking force required by the steel wire rope is calculated, according to the minimum breaking force required, the steel wire rope specification table is consulted, and the steel wire rope with appropriate diameter is selected. Generally speaking, the larger the diameter, the stronger the carrying capacity of the steel wire rope, but it will also increase the cost and weight. According to the specific requirements of the hoisting operation and the safety factor, the steel wire rope with appropriate strength grade is selected. Generally, the safety factor should not be less than the specified value to ensure the safety of the hoisting operation.

[0035] When working, the driving mechanism drives the drum 2 to rotate, tightens the steel wire rope 1, and the balance mechanism 5 and the lifting mechanism 6 are tilted, which is consistent with the tilting direction of the gate, reduces the friction between the gate and the groove, and the steel wire rope will not contact and rub with the edge of the groove, which greatly ensures the safety of lifting.

[0036] Embodiment 2

[0037] The inclined hoisting winch in this embodiment includes a frame 7 and a driving mechanism fixed on the upper surface of the frame 7, the output end of the driving mechanism is coaxially connected with the drum 2, the lower end of the frame 7 is hinged with the balance mechanism 5, the steel wire rope 1 is wound on the drum 2, the steel wire rope 1 passes through the lifting mechanism 6 and the balance mechanism 5 suspended below the frame 7 in turn, and then passes through the lifting mechanism 6 again, and returns to be wound on the drum 2, both ends of the steel wire rope 1 are fixed on the drum 2.

[0038] The driving mechanism includes a motor 3, the output end of the motor 3 is connected with the high-speed shaft of the speed reducer 4 through a shaft coupling, and the low-speed shaft of the speed reducer 4 is the output end of the driving mechanism.

[0039] When in use, the motor 3 is started, the required rotating speed is adjusted through the shaft coupling to drive the speed reducer 4, the rotation of the drum 2 is controlled, the steel wire rope 1 is tightened, and the balance mechanism 5 is tilted in the hoisting direction.

[0040] The specific components included in the driving mechanism can be increased or decreased according to actual needs.

[0041] The driving mechanism can also include an overload protection, which can realize its function through an electrical control system or a mechanical device, such as a thermal relay, an overload clutch, etc. These devices can automatically cut off the power supply or separate the transmission parts when overloaded, and the driving mechanism will automatically stop working to protect the winch and the driving mechanism from being damaged.

[0042] The shaft coupling and the speed reducer 4 in this embodiment can also be replaced according to actual needs to improve the transmission efficiency and carrying capacity.

[0043] The shaft coupling can be a rigid shaft coupling or an elastic shaft coupling according to the transmission torque between the motor 3 and the speed reducer 4 and the relative displacement of the two shafts.

[0044] According to the power and speed of the hoist winch, the required torque to be transmitted is calculated, and the rated torque should be greater than the required torque to be transmitted. If there is relative displacement between the two shafts, an elastic coupling that can compensate for the relative displacement should be selected, and if the alignment of the two shafts is required to be higher, a rigid coupling can be selected.

[0045] The reducer 4 is provided to reduce the high speed of the motor 3 to a lower speed suitable for actual needs, while the torque can be increased to improve the lifting power of the winch. The reducer reduces the high speed of the motor to a speed suitable for the drum of the winch through a larger transmission ratio, and at the same time, according to the principle of constant power, the torque of the output shaft of the reducer is increased accordingly.

[0046] The reducer 4 can also match the speed and torque requirements of different components, including the motor, brake, drum and other components in the winch system, each of which has different requirements for speed and torque. The reducer can play a coordinating role to make the movement between components more matched and improve the overall performance of the system. At the same time, through reasonable design of the reduction ratio, the reducer can control the speed change of the winch drum, making the lifting and lowering process of the heavy object more stable, reducing impact and vibration, and protecting the equipment and the hoisted object.

[0047] When selecting a suitable reducer 4, the required parameters should be determined first, and then the working environment should be considered.

[0048] The input parameters of the reducer are determined according to the motor power and speed of the winch. Ensure that the reducer can withstand the output power of the motor and match the speed of the motor. Then, according to the working requirements of the winch, determine the required output torque and speed, the output torque should meet the requirements of lifting heavy objects, and the output speed should be adapted to the speed of the drum. Finally, according to the requirements of the input speed and the output speed, calculate the required transmission ratio, which determines the degree of reduction of the reducer and affects the lifting speed and capacity of the winch.

[0049] If the winch works in high temperature or low temperature environment, the reducer that can adapt to the corresponding temperature range should be selected. In high temperature environment, the reducer with good heat dissipation performance should be selected; in low temperature environment, the reducer that can operate normally at low temperature should be selected. If the winch works in a humid or dusty environment, a reducer with good protection performance should be selected. A reducer with good sealing performance can be selected to prevent water and dust from entering the interior and affecting the normal operation of the reducer.

[0050] Example 3

[0051] The inclined hoisting winch in the embodiment comprises a rack 7 and a driving mechanism fixed on the upper surface of the rack 7, the output end of the driving mechanism is coaxially connected with the winding drum 2, the lower end of the rack 7 is hingedly connected with the balancing mechanism 5, the steel wire rope 1 is wound on the winding drum 2, the steel wire rope 1 passes through the hoisting mechanism 6 and the balancing mechanism 5 in turn and is suspended below the rack 7, and then passes through the hoisting mechanism 6 again and is returned to be wound on the winding drum 2, and the two ends of the steel wire rope 1 are fixed on the winding drum 2.

[0052] The driving mechanism comprises a motor 3, the output end of the motor 3 is connected with the high-speed shaft of the speed reducer 4 through a shaft coupling, and the low-speed shaft of the speed reducer 4 is the output end of the driving mechanism.

[0053] The winding drum 2 is axially divided into a first winding area and a second winding area, and the two ends of the steel wire rope 1 are wound in the first winding area and the second winding area respectively.

[0054] The winding drum 2 simultaneously winds the two ends of the steel wire rope in the same direction, which is easy to cause the rope to be tangled, the two steel wire ropes interfere with each other on the winding drum, and the two steel wire ropes can cross, overlap or even knot, so that the steel wire rope is unevenly stressed and the service life is reduced.

[0055] In the embodiment, the winding drum 2 is divided into different areas, which can guide the two ends of the steel wire rope 1 to accurately enter the correct position of the winding drum, prevent the two ends of the steel wire rope 1 from being tangled when rotating, and improve the safety of the hoisting process.

[0056] The winding drum is the core component of the winch, and when the winding drum is inclined, the winding drum needs to adapt to the inclined winding of the steel wire rope. The surface groove of the winding drum can also be specially designed, for example, the groove depth is deepened, the spiral angle of the groove is changed, etc., to ensure that the steel wire rope can be stably wound on the winding drum in an inclined state, and to avoid phenomena such as rope skipping and rope tangling.

[0057] The winding drum 2 can also be equipped with other guiding devices to guide the two ends of the steel wire rope 1 to accurately enter the correct position of the winding drum 2. The guiding device can be a pulley, a guide wheel or a guide pipe, etc., which can limit the movement track of the steel wire rope, so that it can only be wound on the winding drum according to the predetermined direction.

[0058] The strength of the winding drum can also be enhanced during actual use. Since the direction and size of the force of the steel wire rope on the winding drum are different from those during vertical hoisting when the winding drum is inclined, the winding drum needs to bear greater lateral force and bending stress. Therefore, the material and structure of the winding drum will be strengthened, thicker steel plates can be used, and reinforcing ribs can be added to improve the strength and rigidity of the winding drum, so as to ensure that the winding drum can work normally and is not easy to deform or be damaged during the inclined hoisting process.

[0059] Embodiment 4

[0060] The inclined hoisting winch in the embodiment comprises a rack 7 and a driving mechanism fixed on the upper surface of the rack 7, the output end of the driving mechanism is coaxially connected with the winding drum 2, the lower end of the rack 7 is hingedly connected with the balancing mechanism 5, the steel wire rope 1 is wound on the winding drum 2, the steel wire rope 1 passes through the hoisting mechanism 6 and the balancing mechanism 5 in turn and is suspended below the rack 7, and then passes through the hoisting mechanism 6 again and is returned to be wound on the winding drum 2, and the two ends of the steel wire rope 1 are fixed on the winding drum 2.

[0061] The driving mechanism comprises a motor 3, the output end of the motor 3 is connected with the high-speed shaft of the speed reducer 4 through a shaft coupling, and the low-speed shaft of the speed reducer 4 is the output end of the driving mechanism.

[0062] The winding drum 2 is axially divided into a first winding area and a second winding area, and the two ends of the steel wire rope 1 are wound on the first winding area and the second winding area respectively.

[0063] The balancing mechanism 5 is a balancing pulley block, and the axis of the pulley in the balancing pulley block is perpendicular to the axis of the winding drum 2.

[0064] The balancing pulley block is hingedly connected with the rack 7 and does not move with the weight, and is usually composed of a rim, a hub and an axle. The rim is the outer peripheral part of the pulley and is used for winding the steel wire rope 1, the hub is the part connecting the rim and the axle and is usually made of high-strength material to bear a large load, and the axle is the supporting part of the pulley and is hingedly connected with the rack to enable the pulley to rotate freely.

[0065] The working principle of the balancing pulley block is to change the direction and size of the force by rotating the pulley. When the steel wire rope passes through the pulley, according to the principle of force balance, the forces acting on the two ends of the rope are equal in size and opposite in direction. If a force is applied to one end of the rope, the force will be transmitted to the other end through the fixed pulley, thereby achieving force transmission and direction change.

[0066] The balancing pulley block is hingedly connected with the rack 7 and plays a guiding role in the direction of the steel wire rope 1, guiding the steel wire rope 1 to incline and move in the correct direction, the rotation of the balancing pulley block not only balances the forces acting on the two ends of the steel wire rope 1, but also reduces the friction and wear between the steel wire rope and the balancing mechanism 5, disperses the tension of the steel wire rope and improves the safety of hoisting.

[0067] The balancing mechanism 5 can also be provided as other guiding assemblies capable of adjusting the inclination angle to meet different hoisting requirements and inclination angles.

[0068] Embodiment 5

[0069] The inclined hoisting winch in the embodiment comprises a frame 7 and a driving mechanism fixed on the upper surface of the frame 7, the output end of the driving mechanism is coaxially connected with the winding drum 2, the lower end of the frame 7 is hingedly connected with the balancing mechanism 5, the winding drum 2 is wound with the steel wire rope 1, the steel wire rope 1 passes through the hoisting mechanism 6 and the balancing mechanism 5 in turn and is suspended below the frame 7, and then passes through the hoisting mechanism 6 again and is returned to be wound on the winding drum 2, and the two ends of the steel wire rope 1 are fixed on the winding drum 2.

[0070] The driving mechanism comprises the motor 3, the output end of the motor 3 is connected with the high-speed shaft of the speed reducer 4 through a shaft coupling, and the low-speed shaft of the speed reducer 4 is the output end of the driving mechanism.

[0071] The winding drum 2 is axially divided into a first winding area and a second winding area, and the two ends of the steel wire rope 1 are wound in the first winding area and the second winding area respectively.

[0072] The balancing mechanism 5 is a balancing pulley block, and the axis of the pulley in the balancing pulley block is perpendicular to the axis of the winding drum 2. The hoisting mechanism 6 is a movable pulley block, the lower end of the movable pulley block is fixed with a lifting hook, and the lifting hook is provided with a safety device.

[0073] The movable pulley block can reduce the friction between the steel wire rope 1 and the hoisting mechanism during hoisting and reduce the abrasion of the steel wire rope 1. A plurality of guide grooves for the steel wire rope can be arranged on the surface of the movable pulley as needed, so that the steel wire rope can slide more stably according to the guide.

[0074] When selecting the lifting hook, the weight, shape, size and other factors of the hoisted object need to be considered. At the same time, attention should also be paid to the quality of the lifting hook, and a lifting hook with reliable quality and stable performance should be selected to ensure the safety of hoisting operation. The lifting hook can be single or double, and when the gate is large and heavy, a double hook can be selected for hoisting.

[0075] The lower end of the movable pulley block can also be directly hingedly connected to the upper end of the gate to be hoisted.

[0076] Directly hingedly connecting the movable pulley block to the upper end of the gate can reduce the connecting components between the hoisting equipment and the gate, making installation and maintenance more convenient.

[0077] Moreover, since complex lifting tools and connecting components are not needed, the steel wire rope 1 can be directly connected to the movable pulley block, improving the efficiency of installation and maintenance, and avoiding the possibility of the gate unhooking, further improving the safety of the hoisting process.

[0078] The movable pulley block should be selected according to the hoisting weight and requirements to ensure that its carrying capacity meets the requirements. Generally, pulleys made of high-strength steel are selected, which have good wear resistance and carrying capacity. The diameter and strength of the steel wire rope should match the movable pulley block and the hoisting weight, and the fixed bolts should meet the strength requirements.

[0079] The upper end of the gate needs to have sufficient strength to bear the action of the movable pulley set and the lifting force. When designing and installing the movable pulley set, the structure of the upper end of the gate needs to be evaluated to ensure that it can bear the load during lifting. The movable pulley set is installed at the center of the upper end of the gate to ensure the balance of the gate.

[0080] The upper end of the gate can also be reinforced or additional support structures can be added to improve its load-bearing capacity.
