[0021] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not used to limit the present application.
[0022] In order to better understand the technical solutions of the present application, the following will be described in detail in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0024] The elevator safety assessment methods formulated by national assessment standards and relevant local standards in other cities have the following problems: First, there is no objective judgment criterion from the assessment result to the overall conclusion; second, the assessment conclusion is too single and does not comprehensively consider the risks brought by standard updates and changes, and the assessment conclusion is often questioned; third, the assessment method and project settings are not reasonable enough, resulting in doubts about the fairness and scientific nature of the assessment conclusion, and it cannot meet the implementation of the national old elevator renewal and transformation policy work; fourth, the economic weight in the application of the result "old renewal" is not considered. Therefore, how to solve the problem that there is no objective judgment criterion from the assessment result to the overall conclusion in the existing elevator safety assessment method has become an urgent problem to be solved.
[0025] The present application performs update parameter calculation according to the target weights corresponding to each component and the component replacement parameters corresponding to each component to obtain a first elevator update index; performs update parameter calculation according to the total number of elevator landing doors, the total number of car door replacements, and the total number of elevator car doors of the elevator to be evaluated to obtain a second elevator update index; determines the target elevator update result according to the first elevator update index, the second elevator update index, and the elevator update index threshold; and obtains the elevator safety assessment result according to the target elevator update result and the elevator assessment conclusion strategy. By comprehensively considering the calculation formulas of the economic weights of each component of the elevator, the overall replacement conditions of the components, and the whole elevator update conditions, the consistency and scientific nature of the assessment conclusion are improved, and the objective conversion from the assessment conclusion to the result is realized.
[0026] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an elevator safety assessment device capable of realizing the above functions. The following takes the elevator safety assessment as the execution subject as an example to illustrate this embodiment and the following embodiments.
[0027] Based on this, the embodiments of the present application provide an elevator safety assessment method. Refer to Figure 1 , Figure 1 which is a schematic flow chart of the first embodiment of the elevator safety assessment method of the present application.
[0028] In this embodiment, the elevator safety assessment method includes steps S10 to S40: Step S10, perform updated parameter calculation according to the target weight corresponding to each component and the component replacement parameter corresponding to each component to obtain the first elevator update index; It should be noted that in this embodiment, the risk level is determined by comprehensively considering the possible injuries (severity) caused by the considered dangerous situations and the probability level of injury occurrence. Based on the evaluated risk level, the risk is evaluated by determining the corresponding "risk category", and then the specific action measures to be taken are determined, that is, risk analysis and assessment are carried out on related items such as the elevator electrical system, traction system, guiding system, car system, door system, weight and balance system, safety protection system, working area and civil engineering, traction test and function test, hydraulic system test and function test, etc. The risk level is determined based on the failure state of the components, and "risk evaluation index classification" is realized according to different degrees of failure.
[0029] It can be understood that the target weight refers to the economic weight corresponding to the overall replacement of the component, the component replacement parameter refers to the condition factor for the overall replacement of the component, and the first elevator update index refers to one of the whole elevator update indexes for traction-driven elevators, only considering the arithmetic sum of the economic weights corresponding to each component or part to be replaced.
[0030] In specific implementation, by according to the economic weight corresponding to the overall replacement of the component and the condition factor for the overall replacement of the component, and then combining the economic weight corresponding to each preventive measure for each component, the formulation factor of the preventive measure, the serial number of each proposed preventive measure, the serial number divided by component or distribution interval, and the equivalent exhaust stack height, calculate the arithmetic sum of the economic weights corresponding to each component or part to be replaced only, and then obtain the first elevator update index.
[0031] It should be noted that in this embodiment, the economic weights of each component of the evaluation equipment, the overall replacement conditions of the components, and the whole elevator update conditions are calculated through a data model. When the equipment under evaluation is a traction-driven elevator, the calculation method is as follows: If the factor of years is not considered, the whole elevator update index of the traction-driven elevator is calculated according to formula (1).
[0032] ........(1) In the formula: UC1 - one of the whole elevator update indexes for traction-driven elevators, only considering the arithmetic sum of the economic weights corresponding to each component or part to be replaced; P i (P j ) —— The economic weight corresponding to the preventive measures for each component e i (e j ) —— The factor for formulating preventive measures. When the preventive measures for a certain sequence are formulated, then e i (e j ) = 1; Otherwise, e i (e j ) = 0; i(j) —— The sequence code of each formulated preventive measure k —— The sequence code divided by component or distribution range i(j) ∈ k —— The equivalent exhaust stack height, in meters (m) α k —— The condition factor for overall component replacement. When the equipment to be evaluated meets the replacement condition of this component, or due to other non - quantifiable factors, it is considered that this component needs to be replaced as a whole after evaluation, then α k = 1; Otherwise, α k = 0; U k —— The economic weight corresponding to overall component replacement
[0033] Step S20, perform updated parameter calculation according to the total number of elevator landing doors, the total number of car door replacements, and the total number of elevator car doors of the elevator to be evaluated, and obtain the second elevator update index It can be understood that the total number of elevator landing doors refers to the total number of landing doors of the elevator to be evaluated, the total number of car door replacements refers to the number of doors involving the proposed car door or its (zero) components, the total number of elevator car doors refers to the total number of car doors of the elevator to be evaluated, and the second elevator update index refers to one of the traction drive elevator whole - machine update indexes, which only considers the arithmetic sum of the economic weights corresponding to the aging of non - proposed replacement components or parts
[0034] In specific implementation, by calculating the arithmetic sum of the economic weights corresponding to each non - proposed replacement component or part according to the total number of landing doors of the elevator to be evaluated, the number of doors involving the proposed car door or its (zero) components, and the total number of car doors of the elevator to be evaluated, the second elevator update index is obtained
[0035] Step S30, determine the target elevator update result according to the first elevator update index, the second elevator update index, and the elevator update index threshold It can be understood that the elevator update index threshold refers to the reference value of the traction drive elevator whole - machine update index, that is, the product of the sum of the weights corresponding to full component replacement and the update index coefficient. The target elevator update result includes the elevator overall update result and the elevator renovation and maintenance results
[0036] In a specific implementation, the arithmetic sum of the economic weights corresponding to each component or part to be replaced is calculated, and the arithmetic sum of the economic weights corresponding to each component or part not to be replaced is calculated. The sum value of the first elevator update index and the second elevator update index is obtained, and then compared with the reference value of the traction drive elevator whole machine update index. Finally, according to the comparison result, the result of whether the traction drive elevator is to be updated as a whole, that is, the target elevator update result, is obtained.
[0037] In a feasible implementation manner, step S30 may include steps A11 to A12: Step A11, obtaining a target elevator update index according to the first elevator update index and the second elevator update index; It should be noted that the target elevator update index refers to the sum value of the first elevator update index and the second elevator update index. The arithmetic sum of the economic weights corresponding to each component or part to be replaced is calculated, and the arithmetic sum of the economic weights corresponding to each component or part not to be replaced is calculated to obtain the target elevator update index.
[0038] Step A12, comparing the target elevator update index with the elevator update index threshold value to obtain a target elevator update result.
[0039] It can be understood that the sum value of the first elevator update index and the second elevator update index is compared with the reference value of the traction drive elevator whole machine update index, and then according to the comparison result of the sum value of the first elevator update index and the second elevator update index and the reference value of the traction drive elevator whole machine update index, the result of whether the traction drive elevator is to be updated as a whole is determined.
[0040] In a feasible implementation manner, step A12 may include steps B11 to B13: Step B11, comparing the target elevator update index with the elevator update index threshold value to obtain an elevator index comparison result; It can be understood that the elevator index comparison result refers to the comparison result of the sum value of the first elevator update index and the second elevator update index and the reference value of the traction drive elevator whole machine update index.
[0041] In a specific implementation, to determine whether the conditions for the overall update of the traction drive elevator are met, the sum value of the first elevator update index and the second elevator update index is compared with the reference value of the traction drive elevator whole machine update index, and the comparison result of the sum value of the first elevator update index and the second elevator update index and the reference value of the traction drive elevator whole machine update index is obtained.
[0042] Step B12: When the comparison result of the elevator indicators shows that the updated indicators of the target elevator are not less than the elevator update indicator threshold, determine that the target elevator update result is the overall elevator update result. It can be understood that the overall elevator update result refers to the result that meets the conditions for the overall update of the traction drive elevator.
[0043] In a specific implementation, when the comparison result of the elevator indicators shows that the sum of the first elevator update indicator and the second elevator update indicator is not less than the reference value of the overall update indicator of the traction drive elevator, it indicates that the elevator has no repair value and it is recommended to perform an overall update. That is, determine that the target elevator update result is the result that meets the conditions for the overall update of the traction drive elevator.
[0044] Step B13: When the comparison result of the elevator indicators shows that the updated indicators of the target elevator are less than the elevator update indicator threshold, determine that the target elevator update result is the elevator renovation and repair result.
[0045] It can be understood that the elevator renovation and repair result refers to the result that does not meet the conditions for the overall update of the traction drive elevator, that is, the result of renovating and repairing the elevator as needed.
[0046] In a specific implementation, when the comparison result of the elevator indicators shows that the sum of the first elevator update indicator and the second elevator update indicator is less than the reference value of the overall update indicator of the traction drive elevator, it indicates that corresponding suggestions are put forward according to the construction category. That is, determine that the target elevator update result is the result that does not meet the conditions for the overall update of the traction drive elevator.
[0047] It should be noted that a reference value needs to be set for the overall elevator update indicator to define whether an overall update is required. Generally: ...........(2) In the formula: UC 基准1 —— The reference value of the overall update indicator of the traction drive elevator, that is, the product of the sum of the weights corresponding to the replacement of all components and the update indicator coefficient; 0.5 —— The update indicator coefficient. Finally, the overall update conditions of the traction drive elevator can be analyzed according to formula (3): ........(3) In a feasible implementation manner, steps C11~C12 may also be included before step S30: Step C11: When the elevator changes the landing door scenario, calculate according to the total number of landing door replacements, the total number of elevator floors, and the height correction factor to obtain the landing door correction factor. It can be understood that the elevator car door replacement scenario refers to the scenario of replacing only part of the car doors. The total number of car doors replaced refers to the number of doors involving the replacement of car doors or their (zero) components. The total number of floors of the elevator refers to the total number of floors of the elevator to be evaluated. The height correction factor refers to the lift height correction factor, and the lift height correction factor is to consider the influence of the lift height of the elevator on its operating efficiency, energy consumption, and the wear degree of key components. The car door correction factor is used to adjust the differences brought about by different car door designs in elevator evaluation.
[0048] In specific implementation, in the scenario of replacing only part of the car doors, calculations are carried out through the number of doors involving the replacement of car doors or their (zero) components, the total number of floors of the elevator to be evaluated, and the lift height correction factor to obtain the correction factor for adjusting the differences brought about by different car door designs in elevator evaluation, that is, the car door correction factor.
[0049] In a feasible implementation manner, before step C11, steps D11 - D12 can also be included: Step D11, obtain the rated speed and rated load of the elevator to be evaluated; It can be understood that the rated speed refers to the maximum speed designed for the elevator under normal operating conditions, and the rated load refers to the maximum weight allowed to be loaded in the elevator car.
[0050] Step D12, determine the height correction factor according to the preset height factor mapping relationship, the rated speed, and the rated load.
[0051] It can be understood that the preset height factor mapping relationship refers to the pre - set mapping relationship between the rated speed and the rated load and the lift height correction factor.
[0052] In specific implementation, based on the pre - set mapping relationship between the rated speed and the rated load and the lift height correction factor, combined with the maximum speed designed for the elevator to be evaluated under normal operating conditions and the maximum weight allowed to be loaded in the elevator car, the corresponding lift height correction factor is determined.
[0053] Step C12, correct the initial update index threshold according to the car door correction factor to obtain the elevator update index threshold.
[0054] It can be understood that the initial update index threshold refers to the uncorrected benchmark value of the elevator whole - machine update index in the scenario of replacing only part of the car doors, and the elevator update index threshold refers to the corrected benchmark value of the elevator whole - machine update index.
[0055] In a specific implementation, based on the correction factor used to adjust the differences caused by different landing door designs in elevator evaluation, the benchmark value of the elevator complete machine update index that is not corrected in the scenario of only replacing some landing doors is corrected to obtain the corrected benchmark value of the elevator complete machine update index.
[0056] It should be noted that for a more scientific and reasonable calculation, a correction factor β for the lifting height needs to be introduced, and this correction factor β depends on the rated speed and rated load of the elevator to be evaluated. As shown in Table 1, the correction factor β can be obtained by looking up Table 1.
[0057] Table 1:
[0058] It should be noted that for the case of only replacing some landing doors, the correction factor of the landing door needs to be further corrected, and a correction factor is introduced. When the number of landing doors x to be replaced = 1, then = 1; when the number of landing doors to be replaced is equal to the total number of floors, that is, x = m, then = is established. A linear equation is established, and the economic weight correction factor of the landing door corresponding to any number of landing doors to be replaced is calculated according to formula (4).
[0059] .....................(4) In the formula: x - the number of doors involving the replacement of landing doors or their (zero) components; m - the total number of floors of the elevator to be evaluated; - the correction factor of the landing door; - the correction factor of the lifting height.
[0060] Step S40, obtain the elevator safety assessment result according to the target elevator update result and the elevator evaluation conclusion strategy.
[0061] It can be understood that the elevator evaluation conclusion strategy refers to the strategy of generating the elevator safety assessment conclusion in the mode of a single conclusion + supplementary description, and the elevator safety assessment result refers to the result of evaluating whether there are safety risks in the elevator.
[0062] In specific implementation, according to the result of whether the traction-driven elevator is updated as a whole, a strategy of generating the elevator safety assessment conclusion by combining a single conclusion + supplementary description is adopted to generate the corresponding elevator safety assessment conclusion, and then the result of evaluating whether there are safety risks in the elevator is obtained. For example, if the update result of the target elevator is that the traction-driven elevator is updated as a whole, it is then determined that the suggestion in the elevator safety assessment conclusion is that after safety assessment, no risk factors listed in this document are found; if the update result of the target elevator is that the traction-driven elevator does not need to be updated as a whole, then the suggestions in the elevator safety assessment conclusion are determined according to the construction category, including: replacing with a new elevator, carrying out renovation, and carrying out major repairs, etc. Specifically: in this embodiment, the following conclusions are used in the safety assessment report: After safety assessment, no risk factors listed in this document are found.
[0063] After safety assessment, there are risks in the ××× system or component. Considering the component replacement situation, technical conditions and costs, it is recommended: 1) Replace with a new elevator; 2) Carry out renovation; 3) Carry out major repairs; 4) Carry out general repairs; 5) Strengthen the use management and maintenance.
[0064] Since this elevator was manufactured before the implementation of relevant new standards / safety technical specifications, it is not equipped with a ××× device (function) that meets the requirements.
[0065] Considering the risks brought by the standard update changes comprehensively, the assessment conclusion is more standardized. Adopting the single conclusion + supplementary description mode aims to let the user unit know the "reasons for the need to update the component (or function)", and it cannot be directly associated with the regular inspection conclusion, making the assessment conclusion standardized.
[0066] It should be noted that as Figure 2 shown, the safety assessment in this embodiment includes procedures such as establishing an assessment team, assessment preparation, on-site safety assessment, issuing a safety assessment report, and closed-loop management of assessment and rectification. And the economic weight reference table for each component of the traction-driven elevator is shown in Table 2.
[0067] Table 2:
[0068] In this embodiment, by performing updated parameter calculation based on the target weights corresponding to each component and the component replacement parameters corresponding to each component, a first elevator update index is obtained; by performing updated parameter calculation based on the total number of elevator landing doors, the total number of car door replacements, and the total number of elevator car doors of the elevator to be evaluated, a second elevator update index is obtained; a target elevator update result is determined according to the first elevator update index, the second elevator update index, and the elevator update index threshold; and an elevator safety assessment result is obtained according to the target elevator update result and the elevator assessment conclusion strategy. By comprehensively considering the calculation formulas for the economic weights of each component of the elevator, the overall component replacement conditions, and the overall elevator update conditions, the consistency and scientificity of the assessment conclusion are improved, and the objective conversion from the assessment conclusion to the result is realized.
[0069] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar content as that in the above-mentioned first embodiment can be referred to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 3 , in step S20 of the elevator safety assessment method, steps S21 to S23 are further included: Step S21, determining the elevator aging factor according to the mapping relationship between the elevator service life and the aging factor; It can be understood that the elevator service life refers to the length of time experienced by the elevator since it was put into use, the aging factor mapping relationship refers to the mapping relationship between the elevator service life and the aging factor, and the elevator aging factor refers to a coefficient used to correct the deviation of the weight calculation caused by the difference in the service life of the elevator and its components.
[0070] In specific implementation, through the mapping relationship between the elevator service life and the aging factor, the aging factor corresponding to the length of time experienced by the elevator since it was put into use is found, and then a coefficient used to correct the deviation of the weight calculation caused by the difference in the service life of the elevator and its components, that is, the elevator aging factor, is obtained. The corresponding table of the elevator service life and the aging factor is shown in Table 3.
[0071] Table 3:
[0072] Step S22, calculating the component weights according to the total number of elevator landing doors, the total number of car door replacements, and the total number of elevator car doors of the elevator to be evaluated, to obtain the elevator component weights; It can be understood that the elevator component weights include the arithmetic sum of the economic weights of non-replacement components or parts in other components or intervals except landing doors and car doors, the arithmetic sum of the economic weights of non-replacement landing doors or their parts, and the arithmetic sum of the economic weights of non-replacement car doors or their parts.
[0073] In a specific implementation, the component weights of the elevator are calculated respectively according to the total number of landing doors of the elevator to be evaluated, the number of doors involving the proposed replacement of the car door or its (zero) components, and the total number of car doors of the elevator to be evaluated. Then, the arithmetic sum of the economic weights of the non-proposed replacement components or parts, the arithmetic sum of the economic weights of the non-proposed replacement landing doors or their parts, and the arithmetic sum of the economic weights of the non-proposed replacement car doors or their parts in other components or intervals except for landing doors and car doors are obtained. The above calculation results are summarized to obtain the elevator component weights.
