[0057] The embodiments of the present invention provide a winch selection method. Referring to Figure 2 , Figure 2 it is a schematic flowchart of the first embodiment of a winch selection method of the present invention.
[0058] In this embodiment, the winch selection method includes the following steps:
[0059] Step S10: Determine the maximum load of a single lifting device according to a pre-set grid model and the mast layout position.
[0060] It should be noted that the execution subject of this embodiment may be the winch selection device, and the winch selection device may be an electronic device such as a personal computer, a tablet computer, a server, or other devices that can implement the same or similar functions. This embodiment does not limit this. In this embodiment and the following embodiments, the winch selection method of the present invention will be described by taking the winch selection device as an example.
[0061] It should be noted that the grid model may be a "1:1" spatial model constructed according to the pre-designed grid design data, and the mast layout position may be the position where the mast is laid out in the grid model. According to the grid model and the mast layout position, the force loads at each mast layout position can be calculated, and then the lifting loads of each lifting device can be obtained according to the force loads and the number of lifting devices set at each mast layout position. The maximum value of the lifting loads of each lifting device is the maximum load of a single lifting device.
[0062] In specific implementation, in order to quickly and reasonably determine the maximum load of a single lifting device, step S10 in this embodiment may include:
[0063] Determine the grid weight and grid contour according to the pre-set grid model;
[0064] Determine the mast force information at each mast layout position according to the mast layout position, the grid weight and the grid contour;
[0065] Obtain the maximum value in the mast force information to obtain the maximum force information;
[0066] Determine the maximum load of a single lifting device according to the number of lifting devices at each mast layout position and the maximum force information.
[0067] It should be noted that since the grid model is a "1:1" spatial model constructed based on the pre-designed grid design data, and the grid design data may include data such as the grid material used and the grid structure, the grid weight and grid contour can be determined according to the grid model.
[0068] In specific implementation, the grid model can be constructed using a pre-set grid design software. Among them, the pre-set grid design software may be MST series space structure design software, for example: MST2016 or MST2020. Determining the mast force information at each mast layout position according to the mast layout position, the grid weight and the grid contour may be to calculate the grid weight and grid contour through the pre-set grid design software, then mark the mast layout position in the pre-set grid design software, and set a simulated mast at the mast layout position according to the on-site mast parameters, and finally calculate the mast force information at each mast layout position through the pre-set grid design software.
[0069] It should be noted that the maximum load of a single lifting device can be determined by dividing the maximum force information by the number of lifting devices at the mast layout position, so as to obtain the maximum load of a single lifting device.
[0070] It can be understood that the number of lifting devices set at each mast layout position is the same. Therefore, the lifting load of a single lifting device at the maximum force information is the maximum load of a single lifting device.
[0071] Step S20: Select a target sling according to the maximum load and the equipment parameters of the lifting device, and obtain the lifting load corresponding to the target sling.
[0072] It should be noted that the lifting device can be a lifting pulley block, and the equipment parameters of the lifting device can include parameters such as the number of working lines of the pulley block, the efficiency of the pulley block, and the efficiency of the guiding pulley. According to the maximum load of a single lifting device and the equipment parameters of the lifting device, the minimum performance parameters of the applicable steel wire rope can be calculated. According to the performance parameters, the specification parameters of the minimum applicable sling can be determined, so as to select the target sling. The sling can be a steel wire rope, and different specifications of slings have different lifting loads, that is, the maximum load within the safe range of the sling. Obtaining the lifting load corresponding to the target sling can be to find the corresponding lifting load in the preset sling load specification mapping table according to the specification parameters of the target sling. Among them, the specification parameters of the target sling can include the diameter of the steel wire rope, the calculation coefficient, etc., and the preset sling load mapping table can be set in advance by the management personnel of the winch selection equipment according to the steel wire rope use specifications.
[0073] Step S30: Search for selectable winches in the preset winch information database to obtain the first winch set.
[0074] It should be noted that the preset winch information database can be a pre-set database, which stores various winch parameters in advance. The winch parameters can include parameters such as winch type, winch price, winch specification, fast rotation load of the drum, and slow rotation load of the drum.
[0075] In actual use, due to special construction requirements and construction price considerations, not all winches can be used at the construction site. Searching for selectable winches in the preset winch information database to obtain the first winch set can be to determine the selectable winch type and price range according to the construction requirements, search for winch information in the preset winch information database where the winch type is the same as the selectable winch type and the winch price is within the price range, and construct the first winch set according to the found winch information.
[0076] Step S40: Remove the winches with the corresponding fast-rotation load of the drum less than or equal to the lifting load from the first set of winches to obtain a second set of winches.
[0077] It should be noted that the fast-rotation load of the drum can be the maximum load allowed on the drum of the winch during fast rotation when in use. If the fast-rotation load of the drum corresponding to the winch is less than or equal to the lifting load, it means that when lifting the grid frame, the load of the winch may exceed the fast-rotation load of the drum, and danger may occur. Therefore, the winches with the corresponding fast-rotation load of the drum less than or equal to the lifting load can be removed from the first set of winches, and then the modified first set of winches can be used as the second set of winches.
[0078] For example: Assume that the maximum load is 1.725t, and the first set of winches includes electric winches of four specifications: 1t, 3t, 5t, and 8t. Among them, the fast-rotation load of the drum of the 1t electric winch is less than 1.725t. Therefore, the 1t electric winch can be removed from the first set of winches, and then a second set of winches can be obtained. The second set of winches includes electric winches of three specifications: 3t, 5t, and 8t.
[0079] Of course, in actual use scenarios, when the fast-rotation load of the drum of some winches meets the use requirements, the allowable load of the winch and the slow-rotation load of the drum during operation may not meet the use requirements. Preferably, the winches in the first set of winches can also be screened in combination with the allowable load of the winch and the slow-rotation load of the drum.
[0080] Furthermore, due to the uncertainty of the construction site, various factors may cause the lifting load to exceed the calculated lifting load. If the first set of winches is only filtered based on the lifting load at this time, it may cause the load of the winch to exceed the fast-rotation load of the drum of the target winch during actual construction, thus resulting in danger. To avoid this situation, before step S40 of this embodiment, it may further include:
[0081] Obtain a preset tolerance, and determine a tolerance load according to the preset tolerance and the lifting load;
[0082] Correspondingly, step S40 may include:
[0083] Remove the winches with the corresponding fast-rotation load of the drum less than or equal to the tolerance load from the first set of winches to obtain a second set of winches.
[0084] It should be noted that the preset fault tolerance can be a fixed value pre-set by the management personnel of the selected equipment of the winch, or a proportional value. When the preset fault tolerance is a fixed value, determining the fault tolerance load according to the preset fault tolerance and the lifting load can be to add the preset fault tolerance and the lifting load to obtain the fault tolerance load. When the preset fault tolerance is a proportional value, determining the fault tolerance load according to the preset fault tolerance and the lifting load can be to multiply the preset fault tolerance and the lifting load to obtain the fault tolerance value, and then add the fault tolerance value and the lifting load to obtain the fault tolerance load.
[0085] It can be understood that after determining the fault tolerance load according to the preset fault tolerance and the lifting load, filtering the winches in the first winch set according to the fault tolerance load can make the drum fast rotation loads corresponding to the winches in the finally obtained second winch set all exceed a part of the lifting load of the target sling rope, increasing the fault tolerance, so as to avoid the danger caused by the uncertainty of the construction site and ensure the safety of the construction site.
[0086] For example: Suppose the maximum load is 1.725t and the preset fault tolerance is 0.2t, then the fault tolerance load is 1.925t. The first winch set includes electric winches of four specifications: 1t, 3t, 5t, and 8t. Among them, the drum fast rotation load of the 1t electric winch is less than 1.725t, and the drum fast rotation load of the 3t is 1800 kg, that is, 1.8t. Then, the winches of 1t and 3t specifications need to be removed from the first winch set. At this time, the second winch set obtained includes electric winches of 5t and 8t specifications.
[0087] Step S50: Select a target winch from the second winch set.
[0088] It can be understood that the drum fast rotation loads of the winches in the second winch set are all greater than the lifting load of the target sling rope, that is, the winches in the second winch set all meet the requirements of the construction site. Therefore, a target winch can be selected from the second winch set.
[0089] In actual use, selecting a target winch from the second winch set can be to randomly select a winch from the second winch set as the target winch.
[0090] Furthermore, in order to minimize the construction cost as much as possible while ensuring the safe and normal progress of the construction, step S50 in this embodiment may include:
[0091] Sort the winches in the second winch set in ascending order according to the corresponding drum fast rotation loads to obtain a sorting result;
[0092] Take the winch ranked first in the sorting result as the target winch.
[0093] It should be noted that the higher the fast-rotation load of the winch drum, the higher the price of the winch. All winches in the second winch set can ensure the safe and normal progress of the construction. At this time, in order to reduce the construction cost, the winch with the lowest price in the second winch set can be selected for construction, that is, the winch with the lowest fast-rotation load of the winch drum is selected for construction. Therefore, the winches in the second winch set can be sorted according to the fast-rotation load of the winch drum from small to large to obtain the sorting result, and then the winch ranked first in the sorting result is used as the target winch.
[0094] In this embodiment, the maximum load of a single lifting device is determined according to the pre-set grid model and the mast layout position; the target sling is selected according to the maximum load and the device parameters of the lifting device, and the lifting load corresponding to the target sling is obtained; the available winches are searched in the pre-set winch information library to obtain the first winch set; the winches with the corresponding fast-rotation load of the winch drum less than or equal to the lifting load are removed from the first winch set to obtain the second winch set; the target winch is selected from the second winch set. Since the relevant parameters can be determined according to the grid model and the mast layout position to determine the target sling, and then a suitable winch is selected according to the lifting load of the target sling, the user only needs to set the grid model and the mast layout position to automatically select a suitable winch, which can avoid the uncertainty of manually selecting a winch.
[0095] Reference Figure 3 , Figure 3 is a schematic flowchart of the second embodiment of a method for selecting a winch according to the present invention.
[0096] Based on the above first embodiment, step S20 of the method for selecting a winch in this embodiment includes:
[0097] Step S201: Determine the running rope tension according to the maximum load and the device parameters of the lifting device.
[0098] It should be noted that the running rope can be the sling with the fastest speed during the operation of the lifting device. The running rope tension can be the tension of the sling with the fastest speed during the operation of the lifting device. The device parameters of the lifting device can include parameters such as the number of working lines of the pulley block, the efficiency of the pulley block, and the efficiency of the guiding pulley.
[0099] In actual use, step S201 of this embodiment can include:
[0100] Calculate the running rope tension according to the maximum load and the device parameters of the lifting device through a pre-set tension calculation formula;
[0101] The pre-set tension calculation formula is:
[0102] S = T / n / η / η0
[0103] Wherein, S is the running rope tension, T is the maximum load, n is the number of working lines of the pulley block, η is the efficiency of the pulley block, and η0 is the efficiency of the guiding pulley.
[0104] Step S202: Determine the critical value of the breaking force according to the running rope tension and the standard safety factor.
[0105] It should be noted that the standard safety factor can be the safety factor of the wire rope corresponding to the sling rope, and the standard safety factor can be pre-set by the management personnel of the equipment selected by the winch according to the type of wire rope used at the construction site. Determining the critical value of the breaking force according to the running rope tension and the standard safety factor can be multiplying the running rope tension by the standard safety factor to obtain the critical value of the breaking force.
[0106] Step S203: Select a target sling rope from the preset rope information table according to the critical value of the breaking force.
[0107] It should be noted that the preset rope information table can include the specification parameters of various wire ropes that can be used at the construction site. The specification parameters of the wire rope can include parameters such as the breaking force of the wire rope, the diameter of the wire rope, and the price of the wire rope. Selecting a target sling rope from the preset rope information table according to the critical value of the breaking force can be selecting a wire rope with a corresponding wire rope breaking force greater than the critical value of the breaking force in the preset rope information table as the target sling rope.
[0108] In a specific implementation, in order to minimize the construction cost as much as possible while ensuring the normal progress of the construction, step S203 in this embodiment may include:
[0109] Search for ropes in the preset rope information table whose corresponding rope breaking forces are greater than the critical value of the breaking force to obtain a set of candidate ropes;
[0110] Sort the ropes in the set of candidate ropes according to the corresponding rope breaking forces from small to large to obtain a rope sorting result;
[0111] Take the rope ranked first in the rope sorting result as the target sling rope.
[0112] It should be noted that first, it is necessary to ensure that the wire rope selected as the target sling rope meets the actual construction requirements. Therefore, it is possible to search for ropes in the preset rope information table whose corresponding rope breaking forces are greater than the critical value of the breaking force, and then construct a set of candidate ropes according to the found ropes. At this time, all the ropes in the set of candidate ropes meet the actual construction requirements.
[0113] In actual use, the larger the diameter of the wire rope, the higher the corresponding rope breaking force. Correspondingly, the unit price of the wire rope is also higher. In order to reduce the construction cost, it is necessary to select the rope with the lowest price among the wire ropes that meet the construction conditions, that is, the rope with the smallest rope breaking force. Therefore, the ropes in the set of candidate ropes can be sorted according to the corresponding rope breaking forces from small to large to obtain the rope sorting result; then the rope ranked first in the rope sorting result is used as the target sling rope.
[0114] Step S204: Obtain the lifting load corresponding to the target sling rope.
[0115] It should be noted that obtaining the lifting load corresponding to the target sling rope can be to look up the corresponding lifting load in the preset sling load specification mapping table according to the specification parameters of the target sling rope. Among them, the specification parameters of the target sling rope can include the wire rope diameter, calculation coefficient, etc., and the preset sling load mapping table can be set in advance by the management personnel of the winch selection equipment according to the wire rope use specifications.
[0116] In this embodiment, the running rope tension is determined according to the maximum load and the equipment parameters of the lifting equipment; the critical breaking force value is determined according to the running rope tension and the standard safety factor; the target sling rope is selected from the preset rope information table according to the critical breaking force value; the lifting load corresponding to the target sling rope is obtained. Since the target sling rope is selected according to the running rope tension that can represent the maximum running tension of the winch, the selected target sling rope can meet the actual construction requirements, so that the finally selected winch is more reasonable, and the reliability of the winch selection method of the present invention is improved.
[0117] In addition, an embodiment of the present invention also proposes a storage medium, on which a winch selection program is stored. When the winch selection program is executed by a processor, the steps of the winch selection method as described above are implemented.
[0118] Refer to Figure 4 , Figure 4 which is the structural block diagram of the first embodiment of the winch selection device of the present invention.
[0119] As Figure 4 shown, the winch selection device proposed by the embodiment of the present invention includes:

[0121] A data selection module 20, configured to select a target sling rope according to the maximum load and the equipment parameters of the lifting equipment, and obtain the lifting load corresponding to the target sling rope;
[0122] The data query module 30 is used to search for available winches in a preset winch information library to obtain a first set of winches;
[0123] The data filtering module 40 is used to remove winches with a corresponding fast-reverse load of the drum less than or equal to the lifting load from the first set of winches to obtain a second set of winches;
[0124] The winch selection module 50 is used to select a target winch from the second set of winches.
[0125] In this embodiment, the maximum load of a single lifting device is determined according to a preset grid model and the mast layout position; a target sling is selected according to the maximum load and the device parameters of the lifting device, and the corresponding lifting load of the target sling is obtained; available winches are searched in a preset winch information library to obtain a first set of winches; winches with a corresponding fast-reverse load of the drum less than or equal to the lifting load are removed from the first set of winches to obtain a second set of winches; a target winch is selected from the second set of winches. Since relevant parameters can be determined according to the grid model and the mast layout position to determine the target sling, and then a suitable winch is selected according to the lifting load of the target sling, the user only needs to set the grid model and the mast layout position to automatically select a suitable winch, which can avoid the uncertainty of manually selecting a winch.
[0126] Further, the data filtering module 40 is further used to obtain a preset tolerance amount, and determine a tolerance load according to the preset tolerance amount and the lifting load;
