Abstract

The utility model discloses a multifunctional measuring instrument used for laying the main cable strand of a suspension bridge. The multifunctional measuring instrument comprises a reference strand, a strand to be adjusted, and a bottom leveling ruler. Vertical rulers perpendicular to the bottom leveling ruler are fixed on the two ends of the bottom leveling ruler. Concave slideways are disposed on the inner sides of the vertical rulers. A top leveling ruler capable of moving up and down along the concave slideways is disposed between the two vertical rulers. The bottom of the reference strand is tightly abutted against the top of the bottom leveling ruler. When measurement is performed, the bottom of the top leveling ruler is tightly abutted against the top of the strand to be adjusted. The bottom leveling ruler, the top leveling ruler, and the vertical rulers are all equipped with more than one horizontal level pipes and more than one vertical level pipes. The multifunctional measuring instrument achieves simple, safe, reliable, and easy and fast measurement in the construction process of laying the main cable strand of a suspension bridge and increases the accuracy of the measurement. In addition, the multifunctional measuring instrument has characteristics of easy use, low cost, easy carrying, saving a lot of manpower and material resources, and increasing work efficiency to a great extent.

Description

A kind ofly set up polymeter for the main rope of suspension bridge strand
Technical field
The utility model relates to a kind of main rope of suspension bridge strand and sets up measuring instrument, particularly a kind ofly sets up polymeter for the main rope of suspension bridge strand.
Background technology
At present in the work progress of main rope of suspension bridge strand, for determining that the survey instrument that adopts is generally huge vernier caliper or general simple guiding ruler when transferring the accurate distance of strand and general strand.Although huge vernier caliper precision is high, but due to the weight of self very heavy (the vernier caliper weight of setting up measurement for the main rope of suspension bridge strand generally is about 30kg), usually need 3 ~ 4 people's combination process, this brings great potential safety hazard for the measurement operation in high-altitude, moreover because the cooperation between several survey crews in measuring process needs highly tacit agreement, not so will greatly reduce measuring accuracy; If use simple guiding ruler to measure, survey measurements mainly relies on the visual estimation of scale is carried out, and therefore, this type of is measured operation and makes precision to be guaranteed; In addition the adjustment of the main cable strand absolute altitude of suspension bridge usually at dead of night 12 carry out to 6 of mornings, the adjustment cycle of single strand absolute altitude generally needs 2 hours, the accent rope time at night seems very urgent and precious, therefore must be precisely and rapidly for the measurement of strand relative position.
Summary of the invention
Technical problem to be solved in the utility model is, not enough for prior art, provide a kind of and set up polymeter for the main rope of suspension bridge strand, make that surveying work in main rope of suspension bridge strand erection construction process becomes simply, safety, reliable, save a large amount of manpower and materials, increase work efficiency.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind ofly set up polymeter for the main rope of suspension bridge strand, comprise Datum Strand and strand to be transferred, also comprise the bottom water leveling ruler, each fixes a perpendicular chi vertical with described bottom water leveling ruler described bottom water leveling ruler two ends, described perpendicular chi inboard is provided with the spill slideway, is provided with the upper water leveling ruler that can move up and down along the spill slideway between described two perpendicular chis; The top of described bottom water leveling ruler is close in described Datum Strand lower end; During measurement, strand described to be transferred upper end is close in described upper water leveling ruler bottom; Be equipped with horizontal level tube and an above vertical level pipe more than one on described bottom water leveling ruler, upper water leveling ruler and perpendicular chi.
The perpendicular chi of bottom water leveling ruler and side direction is fixed by fixing latching, and according to the size of physical size, the upper water leveling ruler can erect chi along side direction and freely do and move up and down.Be equipped with a horizontal level tube and two vertical level pipes on bottom water leveling ruler and upper water leveling ruler, and being equipped with a vertical level pipe and two horizontal level tubes on left side surveyor's staff and right side surveyor's staff, the effect of above level tube is that the surveyor's staff and the perpendicular chi that guarantee polymeter are in respectively the horizontal and vertical state when carrying out the range observation of suspension bridge strand.
Compared with prior art, the beneficial effect that the utility model has is: the utility model makes the surveying work in main rope of suspension bridge strand erection construction process become simple, safe, reliable and more convenient, and improved the precision of measuring, and easy to use, cost is lower, and is easy to carry; Save a large amount of manpower and materials, and improved to a great extent work efficiency.

Embodiment
As shown in figures 1 and 3, the utility model one embodiment comprises Datum Strand 6 and strand 7 to be transferred, also comprise bottom water leveling ruler 1, each fixes the perpendicular chi 2 of a side direction vertical with described bottom water leveling ruler 1 described bottom water leveling ruler 1 two ends, the perpendicular chi of described side direction 2 inboards are provided with spill slideway 16, are provided with the upper water leveling ruler 3 that can move up and down along spill slideway 16 between the perpendicular chi 2 of described two side direction; The top of described bottom water leveling ruler 1 is close in described Datum Strand 6 lower ends; During measurement, strand described to be transferred 7 upper ends are close in described upper water leveling ruler 3 bottoms; Be equipped with two horizontal level tubes 9 and a vertical level pipe 10 on the perpendicular chi 2 of described bottom water leveling ruler 1, upper water leveling ruler 3 and side direction.
As shown in Figure 2, bottom water leveling ruler 1 two ends are provided with the protruding tenon 13 in strap bolt hole 12.
As shown in Figure 3, perpendicular chi 2 one ends of side direction are provided with the spill tenon 14 with described protruding tenon 13 couplings, and spill tenon 14 both sides are provided with bolt hole 15.
Respectively be provided with two horizontal level tubes 9 and a vertical level pipe 10 on described bottom water leveling ruler 1, upper water leveling ruler 3 and perpendicular chi 2, described vertical level pipe 10 is arranged on the middle part of described two horizontal level tube 9 lines.
As shown in Figure 4, upper water leveling ruler 3 two ends are provided with convex slippery fellow 11.
When carrying out general strand and Datum Strand range observation, first perpendicular chi 2 state that both furnishing is vertical of bottom water leveling ruler 1 and side direction, tighten set bolt 4, then, the top of bottom water leveling ruler 1 is adjacent to the lower end of Datum Strand, according to the size of actual range between strand to be transferred and general strand, can upper water leveling ruler 3 is moved freely along the slideway of the perpendicular chi 2 of two side direction, adjust the size of distance, make the bottom of upper water leveling ruler 3 be adjacent to the upper end of strand 7 to be transferred.Then observe each horizontal level tube 9 and vertical level pipe 10, make the surveyor's staff of polymeter and perpendicular chi be in respectively the horizontal and vertical state with vertical direction in the horizontal direction.At last, erecting by side direction scale marker that chi and surveyor's staff carry carries out reading and can complete measurement.
