Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Examples
The embodiment provides an elevator guide rail distribution and guide rail bracket positioning method, which is suitable for a concrete shaft and comprises the following steps:
a. arranging guide rails according to the total height of the hoistway, wherein the length of the first guide rail or the last two guide rails can be changed, and other guide rails are 5m guide rails;
the length of the first guide rail is more than or equal to 3m (because the distance between the first-grade guide rail brackets is 0.6m, the height of the counterweight guardrail is at least 2m specified by the national standard, and the counterweight guardrail is arranged between the first-grade guide rail brackets and the second-grade guide rail brackets, the distance between the second-grade guide rail brackets is at least 2m, considering that the height of the guide rail bracket and the guide rail connecting surface is 100 h, half of the height of the guide rail connecting plate is more than or equal to 0.12, so that the height is 0.6+2+0.1+0.12 which is more than or equal to 3m because the height is 2.82 which is rounded upwards), 3m guide rails or 3.5m guide rails or 4m guide rails or 5m guide rails can be selected, the length of the last guide rail or the last two guide rails is more than 1m, and 1.5m guide rails or 2.5m guide rails or 3m guide rails or 3.5m guide rails or 4m guide rails or 5m guide rails can be selected;
for example, if the total height of the hoistway is 43m, the guide rails are arranged to be 3-5-5-5-5-5-5-5 or 5-5-5-5-5-5-3, and considering the installation of the counterweight guardrail, the short guide rail is generally placed on the first guide rail;
when the guide rails are arranged, if the last guide rail is less than or equal to 1m, the lengths of the last two guide rails can be changed, for example, the total height of a hoistway is 41m, and the guide rail arrangement is 5-5-5-5-5-5-3-3;
the most 5m guide rails (the length of the guide rail in the industry is 1m or 1.5m or 2.5m or 3m or 3.5m or 4m or 5m) have the advantages that the number of the installed guide rails and the number of guide rail connecting plates can be reduced, and if the types of the guide rails are too many, an installer is troublesome to find the guide rails (the weight of one T75 guide rail is about 40 kg);
the implementation method comprises the following steps: inputting the total height of the hoistway and the length of a first guide rail, and analyzing the arrangement of the guide rails by the system, wherein the method comprises the following steps (the following formula only expresses the judgment of one guide rail, and the judgment formulas of other guide rails are changed along with the change of the position of the guide rail);
a1, inputting the length of the first guide rail and the total height of the shaft.
a2, setting 60 guide rails in a row (the height of the shaft is 300m at most, and the height of the shaft on the market can be basically and completely covered), so the rest guide rails are 555 … (till the 60 th guide rail);
a3, according to the input total height of the shaft, using the following formula: IF ($ K $2-SUM ($ G $128: G128))/5000>1,5000, CEILING ($ K $2,500) -SUM ($ G $128: G128)) determines the length of the rail at the location (formula resolution: total height of the hoistway minus the SUM of the height from the first rail to the rail at the location divided by 5000, IF the result is greater than 1, the length of the rail is 5000, otherwise the length of the rail is the total height of the hoistway minus the SUM of the height from the first rail to the rail at the location);
a4, since 60 guide rails are set, the actual total height of the hoistway is not so high, and therefore, the length of the guide rail at the position may be 0 or a negative value calculated according to the above formula, so that if function is used to mask the negative value and 0, and at the same time, considering that the hoistway height is not an integral multiple of 500 (for example, if the last guide rail is 3.2m, the formula is determined and changed to 3.5m), the formula is: IFERROR (CEILING (IF (F127>0, F127, "),500),");
a5, considering that if the length of the top guide rail is less than or equal to 1m, it is basically determined that the top guide rail bracket can only be installed with one-step guide rail bracket, and according to the design principle of at least two guide rail brackets of one guide rail, one-step guide rail bracket is added on the top guide rail, unreasonably, so that the formula of borrowing a little length from the penultimate (5m long guide rail) is obtained (the current formula is that when the length of the top guide rail is 1m, the length of the penultimate guide rail is the average value of the lengths of the two steps of guide rails, and the length of the penultimate guide rail is the sum of the lengths of the remaining two guide rails minus the length of the penultimate guide rail) as follows: IF (E127 ═ 5000, IF (E126> ═ 1500, E127, IF (E126<1500, CEILING ((E126+ E127)/2,500))), IF (E127<1500, SUM (E127: E128) -D128, IF (AND (E127< >4500, E127< > "" ">"), E127, IF (E127 ═ 4500,5000, IF (E127 ═ AND "")))));
a6, after the length of each guide rail is determined, the VBA of the EXCEL is used for assigning the length value of the guide rail in the column to another column of cells:
b. the guide rail support is arranged according to the guide rail arrangement, the distance between the first guide rail supports is 0.6m, the distance between the other guide rail supports is 2.4m according to the design value, and the arrangement and assignment process of the guide rail supports is as follows:
the first gear guide rail bracket interval is 0.6m, the other gear guide rail bracket intervals are 2.4m, the maximum number of guide rail brackets is set to be 123 gears (basically, all floor heights in the industry can be covered), and the guide rail brackets are assigned by EXCEL VBA:
c. judging whether the guide rail bracket is interfered with the guide rail connecting plate or not;
c1, because the guide rail is connected by the guide rail connecting plate, in order to prevent the guide rail bracket and the guide rail connecting plate from interfering, the specific position of the guide rail connecting plate must be known (the following formula only expresses the position of a certain guide rail connecting plate, and the judgment formula of the positions of other guide rail connecting plates changes along with the change of the guide rail position), and the lower limit position of the specific guide rail connecting plate is as follows: B128-Q5/2, and the upper limit position is as follows: f (B127< > ", I127+ $ Q $5,");
c2, the guide rail brackets are arranged according to the upper guide rail bracket, the lower limit of the guide rail bracket is SUM (L127: $ L $128), the upper limit of the guide rail bracket is N127+ $ L $2, when the upper limit of the guide rail bracket is between the upper limit and the lower limit of a certain gear guide rail connecting plate, the guide rail bracket and the guide rail connecting plate are judged to be interfered, and a judgment formula is (only one gear guide rail bracket is interfered to judge, other gear guide rail brackets are interfered, and the formula can be correspondingly changed due to different positions of the guide rail brackets):

only when the lower limit and the upper limit of the guide rail bracket are not between the upper limit and the lower limit of the guide rail connecting plate, the guide rail bracket and the guide rail connecting plate are judged not to be interfered, and the formula is as follows: IF (AND (P127 is "no interference", Q127 is "no interference"), "no interference", or "interference") (the formula is only to judge that a certain stage of the guide rail bracket interferes, AND whether other stages of the guide rail brackets interfere, AND the formula changes accordingly depending on the positions of the guide rail brackets);
c3, for the interference part, the system judges that the human is insensitive to the result, therefore, when judging that the guide rail bracket of a certain gear is interfered, the system displays the interference in red, and the color judgment operation is input in the format judgment;
c4, when assigning the guide rail bracket distance, according to whether a certain guide rail bracket is the last guide rail bracket or not, the concrete formula is as follows: IF (AND ($ K $2> R128, $ K $2< ═ R127), "guide rail bracket spacing up to the last gear" & ($ K $2-R128), L127);
c5, if the distance between the last-gear guide rail brackets is more than 0.6m but less than 2.4m, the distance between the last-gear guide rail brackets is 0.6m, the distance between the last-gear guide rail brackets is newly increased to be the length of the original last-gear guide rail minus 0.6m, if the distance between the last-gear guide rail brackets is less than 0.6m, the distance between the last-gear guide rail brackets is changed to be 0.6m, and the distance between the last-gear guide rail brackets is correspondingly subtracted to be a difference value of 0.6 (for example, if the distance between the first-gear guide rail brackets is 1.6m, the distance between the new last-gear guide rail brackets is 0.6m, the distance between the new last-gear guide rail brackets is 1m, if the distance between the last-gear guide rail brackets is 0.5m, the distance between the new last-gear guide rail brackets is 0.6m, and the distance between the new last-gear guide rail brackets is 2.3m), the formula is: IF (AND (COUNT (S127) < >1, T127>600), T127-600, IF (AND (COUNT (S128) < >1, T128>600),600, IF (AND (COUNT (S127) ═ 1, COUNT (S126) < >1, ($ K $2-R127) < $ 600), T127+ $ K $2-R127-600, T127))) (since the floor height is varied, the guideway support at each location may be the top guideway support for the system, AND thus the decision formula for the different locations may also vary);
c6, adjusting the distance between the guide rail brackets with interference parts according to the judgment result until the system does not have interference judgment of the red parts, wherein, the point to be noticed is that the assignment is that the distance between the guide rail brackets of the last two gears calculated by a formula is input according to the position of the top guide rail of the subsequent judgment, the assignment is that the distance between the guide rail brackets of the first gear is 0.6m, and the distance between the guide rail brackets of the other two gears is 2.4m, and then the problem of interference is judged again after the manual input;
d. judging the grade number of the guide rail bracket on each guide rail, so that each guide rail is at least provided with two grades of guide rail brackets for fixation;
