An establishing method for plumb line, comprises the following steps:
Select the plumb line that two identical, be respectively the first plumb line and the second plumb line, this plumb line comprises cotton rope and is connected to the weight of this cotton rope wherein one end;
Same level is arranged two location points that level interval is H, be respectively primary importance point and second place point, the first plumb line is fixed on primary importance point, and the second plumb line is fixed on second place point, and the weight of two plumb lines is all along gravity direction hanging;
Be provided with traction connecting line between the weight of the first plumb line and the second vertical line, traction connecting line one end is connected with the weight of the first plumb line, and this traction connecting line other end is connected with the weight of the second plumb line;
Make the steady arm that length is greater than H, this steady arm is provided with two slots;
Being installed on by steady arm between the first plumb line and the second plumb line bottom and being positioned at above weight, two plumb lines block respectively and are placed in two slots of steady arm, and after the weight of two plumb lines is stable, two plumb lines form heavy vertical planes.
The length of described traction connecting line is less than H.
Two slots on described steady arm are symmetrical arranged.
Spacing on described steady arm between two slots is greater than H.
Spacing on described steady arm between two slots equals H.
Described steady arm selects lightweight section bar to make.
The inventive method construction is simple, require lower to construction environment, can fast and accurate stable plumb line, apply when being particluarly suitable for lift-mounting in elevator, the installation accuracy of effective raising cage guide, elevator is run more energy-conservation, comfortable and safe, in the serviceable life of effective raising elevator, reduce the failure rate of elevator.

Accompanying drawing 2 is the plan structure schematic diagram of steady arm in the present invention.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the invention will be further described.
Disclosed herein a kind of establishing method of plumb line, apply when being particluarly suitable for lift-mounting in elevator.Application this method, can fast and accurate stable plumb line, thus makes the installation accuracy of cage guide obtain effective guarantee.
An establishing method for plumb line, comprises the following steps:
Step 1, selects the plumb line that two identical, is respectively the first plumb line and the second plumb line, and this plumb line comprises cotton rope and is connected to the weight of this cotton rope wherein one end.
Step 2, same level is arranged two location points that level interval is H, be respectively primary importance point and second place point, the first plumb line is fixed on primary importance point, second plumb line is fixed on second place point, and the weight of two plumb lines is all along gravity direction hanging.These two location points can move, individually can move, also can move together simultaneously, only need ensure that the spacing between these two location points is default H distance, then two plumb lines are fixed tightly on this two positions point respectively, and allow weight suspend in midair downwards.
Step 3, is provided with traction connecting line between the weight of the first plumb line and the second vertical line, traction connecting line one end is connected with the weight of the first plumb line, and this traction connecting line other end is connected with the weight of the second plumb line.The length of traction connecting line is preferably set to and is less than H, and the distance between the weight ensureing the first plumb line and the second plumb line is less than H, and usual difference is in 150 millimeter.By traction connecting line, the weight of the first plumb line with the second plumb line is connected, the tractive force between two weights of two plumb lines is made to be greater than the natural torsion of plumb line self, thus weight is no longer rotated, keep transfixion relative to ground, be convenient to the stable of plumb line.
Step 4, make the steady arm that length is greater than H, this steady arm is provided with two slots.This steady arm selects lightweight section bar to make usually, is easy to carry and takes.When arranging slot, be generally symmetrical arranged on two short sides of steady arm.Spacing on steady arm between two slots is greater than H, or equals H.Steady arm can be location-plate, or angle bar is made, or is made up of cylindrical tubing, does not limit at this.
Step 5, steady arm to be installed between the first plumb line and the second plumb line bottom and to be positioned at above weight, two plumb lines block respectively and are placed in two slots of steady arm, namely the first plumb line card is placed in one of them slot, second plumb line then blocks and is placed in another slot, and plumb line can flexible rotating in slot.Adjust the level angle of steady arm simultaneously, as required by steady arm tilted upward certain angle, make the level interval between the first plumb line above steady arm and the second plumb line equal H, obtain by actual measurement.After stablizing when heavily hanging down, fix the first plumb line and the second plumb line in the horizontal direction respectively, and plumb line still can be twitched in the vertical direction up and down.First plumb line and the second plumb line form a heavy vertical plane, with this heavy vertical plane for reference place, can construct, and keep the accuracy in heavily vertical direction.
As shown in figure 1 and 2, in the specific implementation, as lift-mounting main guide rail in elevator, be first two location point E and F of H at top setting space, first plumb line 21 and the second plumb line 22 are separately fixed at an E and put on F, the then downward hanging of weight of the first plumb line 21 and the second plumb line 22.The traction connecting line 4 that length is less than H is set between the first plumb line and the weight of the second plumb line, makes the tractive force between two weights of two plumb lines be greater than the natural torsion of plumb line self, thus weight is no longer rotated, keep transfixion relative to ground.Make steady arm 3, this steady arm 3 is provided with two slots 23 and 24, and the space D between two slots is greater than or equal to H.In the present embodiment, the space D between two slots is greater than H.First plumb line 21 card is placed in slot 23, second plumb line 22 card is placed in slot 24, adjust the level angle of steady arm simultaneously, as required by steady arm tilted upward certain angle, make the level interval between the first plumb line above steady arm and the second plumb line equal H, obtain by actual measurement.When after stable weight, just fix the first plumb line and the second plumb line in the horizontal direction, two plumb lines can not be moved in the horizontal direction, can vibration up and down in the vertical direction.Now the first plumb line and the second plumb line form a heavy vertical plane, and this heavy vertical plane is object of reference, during construction with this heavy vertical plane for object of reference is constructed, construction is simple, and precision is high when lift-mounting guide rail.
By above method, two plumb lines are set when construction, and utilize corresponding steady arm to be clamped by these two plumb lines, be limited location, make two plumb lines formation as the heavy vertical plane of object of reference, constructability.
It should be noted that, the above for arrange the technical scheme that two plumb lines realize the position determining plumb line fast simultaneously under construction environment, in different construction environments, as required, also more than four plumb lines can be set simultaneously, every two corresponding settings, realize the object determining plumb line fast.Under the prerequisite not departing from creation design of the present invention, any apparent replacement is all within protection scope of the present invention.
