Description

Technical Field

[0001] The invention relates to the field of winch-type gate hoists, in particular to a winch-type gate hoist and a control system thereof. Background Art

[0002] A winch is a small and light lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects. It is also called a winch. The winch can lift vertically, pull horizontally or tilt heavy objects. There are three types of winches: manual winches, electric winches and hydraulic winches. Electric winches are the main type. It can be used alone or as a component of machinery for lifting, road construction and mine hoisting. The winch-type gate hoist is generally composed of multiple sets of winches and gates to form a gate opening and closing system with winches as the main component.

[0003] At present, the winch-type gate hoist in the prior art still has some shortcomings. Most of the winch-type gate hoists are operated by manual control during use, so the degree of automation is insufficient. In the gates of water conservancy projects, the gates are generally hoisted by multiple groups of winches. Therefore, the operating conditions of the multiple groups of winches need to be unified to avoid the expansion of faults caused by the failure of individual winches. Therefore, the control system of the winch-type gate hoist is needed to control and supervise the operation process of the winch-type gate hoist.

[0004] In view of the above technical problems, this application proposes a solution. Summary of the invention

[0005] In the present invention, during the operation of the winch, data is collected from multiple groups of winches at the same time, and the collected results are subjected to data quantification processing. The processed data are used to judge the operating conditions of the multiple groups of winches by means of parallel comparison, so as to ensure that the states of the multiple groups of winches are unified when lifting the gate at the same time, and to avoid gate control problems caused by failures of individual winches. Static analysis is performed on the operating process and static process of the winch-type gate hoist, so as to quantitatively judge whether the operating process of the winch-type gate hoist meets the standard requirements. During the operation of the winch-type gate hoist, the winch-type gate hoist control system performs operation detection and control on the multiple groups of winches in the multiple gate hoists, so as to ensure that the working conditions of the multiple groups of winches are consistent during the operation of the winch, ensure the stable operation of the winch-type gate hoist and the hydraulic gate, solve the problem of lack of an effective control system to ensure the uniform operating conditions of the multiple groups of winches when the winch-type gate hoist is running, and propose a winch-type gate hoist and its control system.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A winch-type gate hoist, comprising a base plate, a bearing seat is fixedly mounted on the upper surface of the base plate, a winding roller is rotatably connected to the bearing seat by means of a bearing, a driving module and a reducer are also fixedly mounted on the upper surface of the base plate, an output end of the driving module is connected to an input end of the reducer via a coupling, one end of the winding roller is fixedly connected to a driven wheel, the driven wheel is rotatably connected to the inside of a reduction housing, the reduction housing is fixedly mounted on the upper surface of the base plate, a driving wheel is rotatably connected to the other end of the reduction housing, the driven wheel and the driving wheel are meshed and connected via a chain, the driving wheel is fixedly connected to the output end of the reducer, and the driving wheel is driven to rotate via the driving module;

[0008] The upper surface of the bottom plate is also rotatably connected to a pulley roller via a bearing structure, a steel cable is hung on the outer surface of the pulley roller, and a steel cable is wound around the outer surface of the winding roller.

[0009] A winch-type hoist control system includes a load collection and protection unit, a load comparison unit, an operation process analysis unit, a travel unified comparison unit and a locking control unit. The load collection and protection unit can collect the load of the winch, and analyze the collected load to determine whether the load has reached a dangerous value, and generate a load overload signal or a load normal signal. At the same time, the load collection and protection unit sends the collected load to the load comparison unit;

[0010] After the load comparison unit obtains the load, it compares the load position and the load value to generate a load comparison signal, outputs the load comparison signal through an output device, and sends the load comparison signal to the operation process analysis unit;

[0011] The unified stroke comparison unit is used to count the steel cable strokes of the winch and to perform quantitative analysis on the counted steel cable strokes. The unified stroke comparison unit compares the strokes of multiple winches in parallel and generates a unified stroke signal or a stroke difference signal according to the parallel comparison result.

[0012] The locking control unit is used to control the locking of the winch, and perform winch travel detection in the state of locking control to obtain the travel distance, and if the travel distance in the locked state is greater than the required locking distance, a locking abnormal signal is generated, and if the travel distance in the locked state is less than or equal to the required locking distance, a locking normal signal is generated;

[0013] The operation process analysis unit can obtain the load through the load acquisition protection unit, and collect the running speed of the winding roller, collect the load and the running speed, and generate an operation analysis result.

[0014] As a preferred embodiment of the present invention, the load acquisition protection unit obtains the traction force output by the driving module through the coupling, amplifies the traction force through the reducer and the gear ratio of the driven wheel and the driving wheel, obtains the traction force after amplification, and records it as the load. The load acquisition protection unit compares the load with the preset safety load. If the load is less than the preset safety load, a normal load signal is generated. If the load is greater than or equal to the preset safety load, a high load signal is generated.

[0015] After generating the overload signal, the load acquisition protection unit transmits the overload signal to the display device through the signal port.

[0016] As a preferred embodiment of the present invention, the load comparison unit labels all running winches and records them as i, i=1, 2, 3..., n. The load comparison unit identifies the acquired load and records it as load Fi. The load comparison unit calculates all loads Fi to obtain an average load F0.

[0017] The load comparison unit calculates the difference between the average load F0 and each group of loads Fi to obtain a load deviation fi. The load comparison unit compares the load deviation fi with a preset deviation threshold f0. If the load deviation fi is less than or equal to the preset deviation threshold f0, the i-th group of winches is recorded as a winch with normal load. If the load deviation fi is greater than the preset deviation threshold f0, the i-th group of winches is recorded as a winch with abnormal load.

[0018] The load comparison unit compares the number of hoists with normal loads and hoists with abnormal loads, and generates a comparison pass signal if the number of hoists with abnormal loads is less than a preset value, and generates a comparison abnormal signal if the number of hoists with abnormal loads is greater than the preset value, wherein the comparison abnormal signal and the comparison pass signal are load comparison signals;

[0019] After the operation process analysis unit obtains the comparison abnormality signal, the operation of the winch is stopped and a warning reminder is generated. After the operation process analysis unit obtains the comparison pass signal, the operation of the winch is allowed.

[0020] As a preferred embodiment of the present invention, when the unified travel comparison unit performs statistics on the steel cable travel of the winch, the travel of the steel cable is recorded as S, and the travel of the steel cables of different winches is recorded as Si. The unified travel comparison unit performs error processing on the steel cable travel Si of each winch to obtain the steel cable travel range Hi, Hi = *Si, where q is a preset error range, q = 0.02;

[0021] The unified travel comparison unit compares the steel cable travel ranges Hi, and records the steel cable travel ranges Hi with the largest number of the same as the standard travel range, and records the steel cable travel ranges Hi different from the standard travel range as the abnormal travel range. If the number of abnormal travel ranges is greater than a preset value, a travel difference signal is generated; if the number of abnormal travel ranges is less than or equal to the preset value, a unified travel signal is generated.

[0022] As a preferred embodiment of the present invention, the method for the unified stroke comparison unit to determine whether the rope stroke ranges Hi are the same is:

[0023] The steel cable travel range Hi is recorded as a set, and at least two sets of sets are compared. If there is a common intersection between the sets involved in the comparison, the steel cable travel ranges Hi involved in the comparison are recorded as the same.

[0024] As a preferred embodiment of the present invention, after the operation process analysis unit obtains the operating speed and load, it calculates the operating power according to the operating speed and load. If the operating power is greater than the preset load power, a high-load operation alarm is generated and a reminder is given through an audible and visual alarm device. If the operating power is less than or equal to the preset load power, no response is given.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In the present invention, during the operation of the winch-type gate hoist, the operation of multiple groups of winches in the multiple gate hoists is monitored and controlled by the winch-type gate hoist control system to ensure that the working conditions of the multiple groups of winches are consistent during the operation of the winches, ensure the stable operation of the winch-type gate hoist and the water conservancy gate, and extend the service life of the winch-type gate hoist.

[0027] 2. In the present invention, during the operation of the winches, data is collected from multiple groups of winches at the same time, the collected results are subjected to data quantification processing, and the processed data are used to judge the operating conditions of the multiple groups of winches by means of parallel comparison, thereby ensuring that the states of the multiple groups of winches are unified when lifting the gate at the same time, thereby avoiding problems with gate control due to failures of individual winches.

[0028] 3. In the present invention, by statically analyzing the operation process and stationary process of the winch-type gate hoist, it is quantitatively judged whether the operation process of the winch-type gate hoist meets the standard requirements. According to the judgment results, it is convenient for management personnel to maintain and manage the winch-type gate hoist in a timely manner, thereby improving the control stability of the winch-type gate hoist in emergency situations.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The upper surface of the base plate 1 is also rotatably connected to a pulley roller 6 through a bearing structure, a steel cable is hung on the outer surface of the pulley roller 6, and a steel cable is wound around the outer surface of the winding roller 2. Multiple sets of winch-type gate hoists are installed above the gate, and the gate is raised and lowered by multiple sets of winch-type gate hoists.

[0039] Embodiment 2:

[0040] See also Figure 1 - Figure 4As shown, a winch-type gate hoist control system includes a load collection and protection unit, a load comparison unit, an operation process analysis unit, a unified stroke comparison unit and a locking control unit. The load collection and protection unit can collect the load of the winch. The load collection and protection unit obtains the traction force output by the drive module 4 through the coupling 5, amplifies the traction force through the reducer 3 and the gear ratio of the driven wheel 9 and the driving wheel 10, obtains the traction force after amplification, records it as the load, and analyzes it according to the collected load. The load collection and protection unit compares the load with the preset safety load. If the load is less than the preset safety load, a normal load signal is generated. If the load is greater than or equal to the preset safety load, a high load signal is generated. At the same time, the load collection and protection unit sends the collected load to the load comparison unit. After generating the high load signal, the load collection and protection unit transmits the high load signal to the display device through the signal port, which serves to remind the management personnel to check.

[0041] The load comparison unit numbers all the running winches and records them as i, i=1, 2, 3..., n. After the load comparison unit obtains the load, it identifies the obtained load and records it as load Fi. The load comparison unit calculates all loads Fi and obtains the average load F0. The load comparison signal is generated by comparing the load position and the load value, and the load comparison signal is output through the output device. At the same time, the load comparison signal is sent to the operation process analysis unit. The specific load comparison process is as follows:

[0042] Step 1: The load comparison unit calculates the difference between the average load F0 and each group of loads Fi to obtain the load deviation fi. The load comparison unit compares the load deviation fi with the preset deviation threshold f0. If the load deviation fi is less than or equal to the preset deviation threshold f0, the i-th group of winches is recorded as a winch with normal load. If the load deviation fi is greater than the preset deviation threshold f0, the i-th group of winches is recorded as a winch with abnormal load.

[0043] Step 2: The load comparison unit compares the number of hoists with normal loads and hoists with abnormal loads. If the number of hoists with abnormal loads is less than a preset value, a comparison pass signal is generated. If the number of hoists with abnormal loads is greater than the preset value, a comparison abnormal signal is generated. The comparison abnormal signal and the comparison pass signal are the load comparison signal.

[0044] Step 3: After the operation process analysis unit obtains the comparison abnormal signal, the winch is stopped and a warning reminder is generated. After the operation process analysis unit obtains the comparison pass signal, the winch is allowed to run.

[0045] The unified travel comparison unit is used to count the steel cable travel of the winch and perform quantitative analysis on the counted steel cable travel. The unified travel comparison unit compares the travels of multiple winches in parallel and generates a unified travel signal or a travel difference signal according to the parallel comparison result. When the unified travel comparison unit counts the steel cable travel of the winch, the steel cable travel is recorded as S and the steel cable travels of different winches are recorded as Si. The unified travel comparison unit performs error processing on the steel cable travel Si of each winch to obtain the steel cable travel range Hi, Hi = 1 ± q * Si, where q is a preset error range, q = 0.02;

[0046] The unified travel comparison unit compares the wire rope travel ranges Hi, and records the wire rope travel ranges Hi with the largest number of the same travel ranges as the standard travel ranges, and records the wire rope travel ranges Hi different from the standard travel ranges as abnormal travel ranges, and generates a travel difference signal if the number of abnormal travel ranges is greater than a preset value, and generates a unified travel signal if the number of abnormal travel ranges is less than or equal to the preset value;

[0047] The method for the travel uniform comparison unit to determine whether the cable travel range Hi is the same is as follows:

[0048] The steel cable travel range Hi is recorded as a set, and at least two sets of sets are compared. If there is a common intersection between the sets involved in the comparison, the steel cable travel ranges Hi involved in the comparison are recorded as the same.

[0049] The locking control unit is used to control the locking of the winch, and to detect the winch travel in the locked state to obtain the travel distance. If the travel distance in the locked state is greater than the required locking distance, a locking abnormality signal is generated. If the travel distance in the locked state is less than or equal to the required locking distance, a locking normal signal is generated to avoid the winch from rotating in the locked state and causing the gate to shift. At the same time, after generating the locking abnormality signal, the locking control unit can sound an alarm by means of an audible and visual alarm.

[0050] The operation process analysis unit can obtain the load through the load collection and protection unit, and collect the operating speed of the winding roller 2. After the operation process analysis unit obtains the operating speed and load, the operating power is calculated according to the operating speed and load. If the operating power is greater than the preset load power, a high-load operation alarm is generated and a reminder is given through the sound and light alarm device. If the operating power is less than or equal to the preset load power, no response is given.

[0051] In the present invention, during the operation of the winch, data is collected from multiple groups of winches at the same time, and the collected results are subjected to data quantification processing. The processed data are used to judge the operating conditions of the multiple groups of winches by means of parallel comparison, ensuring that the states of the multiple groups of winches are unified when lifting the gate at the same time, avoiding problems in gate control due to failure of individual winches, and performing static analysis on the operating process and static process of the winch-type gate hoist to quantitatively judge whether the operating process of the winch-type gate hoist meets the standard requirements. During the operation of the winch-type gate hoist, the winch-type gate hoist control system performs operation detection and control on the multiple groups of winches in the multiple gate hoists, ensuring that the working conditions of the multiple groups of winches are consistent during the operation of the winch, and ensuring the stable operation of the winch-type gate hoist and the hydraulic gate.
