In the case of extreme power failure of the traditional electric hoist, it can only be operated manually. The hydraulic hoist has high environmental requirements, difficult to ensure synchronization, and difficult to repair, etc.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0031] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0032] The embodiment of the present utility model provides a multi-functional hoist driving device, as Figures 1 to 5 shown, which includes: an electric hoist 1, a first transmission rod 2 is arranged at the output end of the electric hoist 1, the other end of the first transmission rod 2 is connected to an isokinetic power divider 3, both output ends of the isokinetic power divider 3 are connected to second transmission rods 4, and the other ends of the two second transmission rods 4 are both connected to bevel gear synchronous jack cylinders 5; the axes between the two bevel gear synchronous jack cylinders 5 are perpendicular to the axis of the first transmission rod 2.

[0033] All the above-mentioned mechanisms in this application mainly use nodular cast iron and 304 stainless steel with good corrosion resistance. The electric hoist is installed on the ground, and the rest of the devices are installed underground.

[0034] The principle of this application is as follows: The electric hoist 1 receives an instruction. After rotating and driving the first transmission rod 2, the power enters the constant velocity power divider box 3. After the power is divided into two equal parts (the two powers are of the same magnitude) by the constant velocity power divider box 3, they respectively enter the bevel gear drive top cylinder 5 through the second transmission rod 4. With the forward and reverse rotation of the electric hoist 1, the extension and retraction of the bevel gear drive top cylinder 5 are driven, thereby realizing the drive of the gate.

[0035] By installing the constant velocity power divider box 3 and the bevel gear synchronous top cylinder 5 at different positions, the driving of gates in different opening states can be realized.

[0036] All the electrical parts in this application are located at the upper end of the electric hoist 1. After power failure in extreme weather, it can be manually operated through a manual device, or operated by a rechargeable torque wrench (a square hole and a torque wrench matching hole are added at the handwheel of the electric hoist 1).

[0037] The structure of this application is simple and mainly consists of components such as a motor, a reducer, a transmission mechanism, and a gate. In contrast, the structure of a hydraulic hoist is complex and includes many components such as a hydraulic pump station, a hydraulic cylinder, oil pipes, and valves. The simple structure makes the electric hoist more convenient for maintenance and repair, reducing the maintenance cost.

[0038] At the same time, the electric hoist has the following advantages:

[0039] Faults are easy to troubleshoot: The faults of the electric hoist are usually relatively easy to troubleshoot and diagnose. Due to its relatively simple control and transmission system, once a fault occurs, technicians can quickly determine the fault point by checking components such as electrical circuits, motors, and reducers. However, troubleshooting the faults of a hydraulic hoist is relatively difficult because the faults of the hydraulic system may involve multiple components such as the pump station, oil pipes, valves, and hydraulic cylinders, and professional technicians and testing equipment are required for troubleshooting.

[0040] No need for hydraulic oil: The electric hoist does not require the use of hydraulic oil, avoiding the pollution to the environment and damage to the equipment caused by hydraulic oil leakage. At the same time, it also reduces the procurement, replacement, and disposal costs of hydraulic oil. While the hydraulic hoist needs to regularly replace the hydraulic oil to ensure the normal operation of the system, which increases the maintenance cost.

[0041] In addition, for the double-link mechanism, the electric hoist has stronger synchronism, higher reliability, longer service life, and higher control accuracy than the hydraulic one.

[0042] Compared with traditional driving devices, in the case of extreme power failure, this application can choose to operate with a torque wrench instead of relying on manpower, providing more options and making the operation more intelligent and convenient. At the same time, it provides more reliable support for the inspection and maintenance of the hoist.

[0043] During specific implementation, a first universal joint 6 is provided between the two output ends of the constant velocity transfer case 3 and the second transmission rod 4.

[0044] During specific implementation, a second universal joint 7 is provided between the other ends of the two second transmission rods 4 and the bevel gear synchronous jack cylinder 5.

[0045] Functions of the first universal joint 6 and the second universal joint 7: Eliminate spatial dimension deviation; facilitate installation and disassembly; isolate and reduce vibration.

[0046] During specific implementation, the first transmission rod 2 is a concealed rod type transmission rod.

[0047] During specific implementation, the electric hoist 1 is a multi - rotation electric hoist.

[0048] During specific implementation, the bevel gear synchronous jack cylinder 5 is a mechanical bevel gear synchronous jack cylinder.

[0049] During specific implementation, a square hole and a torque wrench mating hole 101 are provided at the handwheel of the electric hoist 1, and a reaction arm device is installed through the square hole and the torque wrench mating hole.

[0050] During specific implementation, the electric hoist can be communicatively connected to a mobile terminal.

[0051] Of course, this electric hoist can also have the function of intelligent control, and can realize functions such as remote control, preset torque value alarm, and display of valve opening and torque curve. Traditional electric hoists have some limitations during operation. Manual operation is laborious and it is difficult to ensure accuracy. At the same time, remote monitoring and control cannot be achieved, and it is difficult to meet the requirements of some application scenarios that require real - time monitoring and precise control. In addition, the preset torque value cannot be set and alarmed, and important parameters such as valve opening and torque curve cannot be intuitively displayed, which is not conducive to the safe operation and maintenance management of the equipment.

[0052] According to different valves and application scenarios, a suitable torque value is preset for the reaction arm device. When the hoist reaches or exceeds the preset torque value during operation, the system will send an alarm signal to remind the operator to pay attention. This function can effectively prevent damage to the valve or hoist due to excessive force, and improve the safety and reliability of the equipment.

[0053] In addition, the electric hoist can also be equipped with a dedicated mini-program that can display the opening information of the valve and the torque curve of the hoist in real time. Operators can intuitively understand the operating status of the equipment, which is convenient for precise control and adjustment. It is seamlessly connected to the electric hoist through the reaction arm device. The reaction arm device can accurately control the torque output, improve the operation accuracy, and at the same time transmit the torque data to the hoist system to achieve more intelligent control. For example, the reaction arm device can automatically adjust the output torque according to the preset torque value to ensure the accuracy and safety of the operation.

[0054] This device is mainly applied to various gates and weir gates in municipal water conservancy facilities. It meets various opening methods of gates: upward opening, downward opening, flap type, etc. At the same time, the configured electric hoist has mature technology and powerful functions. It can achieve in-place switching, opening feedback, torque protection, limit setting, etc.

[0055] In summary, the present utility model discloses a multi-functional hoist drive device, including: an electric hoist, a first transmission rod is arranged at the output end of the electric hoist, the other end of the first transmission rod is connected to an isokinetic power divider box, both output ends of the isokinetic power divider box are connected to a second transmission rod, and the other ends of the two second transmission rods are both connected to bevel gear synchronous jacks; the axes between the two bevel gear synchronous jacks are perpendicular to the axis of the first transmission rod, so as to achieve rigid hard connection and synchronous transmission. There is no electrical synchronous control and no external factors affecting it, ensuring that there is no displacement, deviation, or distortion when the gate is running. At the same time, through different installation methods, it can easily drive the up-and-down moving gate or the flap type regulating weir gate, with wide applicability.

[0056] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The drawings show the preferred embodiments of the present application, but do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing specific embodiments, or perform equivalent replacements for some of the technical features. Any equivalent structure made directly or indirectly using the content of the specification and drawings of the present application in other related technical fields is equally within the scope of the patent protection of the present application.
