Technical Field
The invention belongs to the field of hydraulic engineering assembly and construction, and particularly relates to a method for installing a multi-hinge gate with hinges below the gate.
Background
The hydraulic turn-down flat plate sluice is widely applied to urban landscape hydraulic engineering and has the functions of water regulation and water supplement. When the gate is opened, the gate is submerged in water, and the influence on the surrounding landscape is little. As shown with reference to fig. 1.
For the gate of the hydraulic downward-turning flat plate sluice, a main beam at the bottom of the gate is usually provided with a plurality of supporting and hinging shaft holes with larger diameters. The plurality of hinges are coaxially arranged, the weight of the rotating hinges is large, and the requirement on installation accuracy is high. The technical requirement is high, the coaxial tolerance requirement of the actual axis and the theoretical axis of the finally installed hinge hole is high and is not more than 0.2mm/m, and the maximum allowable coaxial tolerance of a plurality of hinge rotating points of the gate is small and is not more than 3 mm. Because the gate width is the same with the drill way width, the distance between the door leaf and the gate wall is small, and an installer cannot stand, thereby influencing the installation operation of the side structure of the gate.
The conventional measuring method for the coaxiality of a plurality of reamed holes of the large gate has the following defects that the method comprises instrument observation, laser positioning and the like: the theodolite (or the total station) is used for erecting and observing at the axis of one end, the observation precision is high, the space between the gate and the gate wall is narrow, the requirement for erecting the instrument cannot be met, and the instrument erected in the middle cabin at intervals is difficult to observe from the back view point, position and adjust, measure and observe and the like; the laser pointer is used for fixing the axis, and the precision control is insufficient due to the fact that laser spots are too thick.
Disclosure of Invention

According to an aspect of the present invention, there is provided a method of installing a multi-branched gate, a bottom of which is provided with N first branch hinge holes, wherein the method comprises the steps of:
setting a point on a first gate wall and a second gate wall which need to be provided with a gate as a datum point of a first hinge hole;
hoisting the gate to an installation position, and connecting the datum points on the first gate wall and the second gate wall by piano wires to ensure that the piano wires penetrate through the first hinge holes and do not touch the edges of the first hinge holes;
a bracket for lifting the piano wire upwards is arranged in the middle of the two adjacent first hinge holes, the top of the bracket is adjusted to be horizontal, and the height of the top of the bracket is adjusted to be consistent with that of the reference point;
adjusting the axis of the first hinge hole: uniformly taking more than three detection points on the circumference of each first hinged hole, measuring the distance from each detection point to the piano wire, and adjusting the position of the gate until the difference between the distances from all the detection points to the piano wire meets the design requirement;
adjusting the position of the support hinge seat: enabling the second branch hinge hole on each branch hinge seat to be coaxial with the first branch hinge hole of the corresponding gate;
shaft penetrating: and penetrating the support hinge shaft into the corresponding first support hinge hole and the second support hinge hole.
The installation method of the multi-hinged gate of the invention utilizes the piano wire as the through wire, and the brackets are arranged at intervals to support the piano wire and compensate the sagging amount of the piano wire, thereby achieving the effect of indicating the axis of the piano wire. The technical requirements are met, the coaxiality tolerance of the actual axis and the theoretical axis after all the hinge holes of the gate are finally installed is not more than 0.2mm/m, and the coaxiality tolerance of the hinge rotating points at the position of 25m, the whole length and 6 positions is not more than 3 mm. The installation method is simple to operate and convenient to install.
In some embodiments, a piano wire positioning pulling device is mounted on the gate wall on one side; one end of the piano wire is connected with a datum point on the other side of the gate wall, and the other end of the piano wire is connected with the piano wire positioning and drawing device; and adjusting the piano wire positioning and drawing device to enable the extension line of the piano wire to pass through the datum point on the gate wall on one side.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Finally, it should also be noted that, in this document, relational terms such as first and second, counterclockwise and clockwise are only used to distinguish one entity or operation from another entity or operation without necessarily requiring or implying any actual such relationship or order between such entities or operations. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 2 schematically shows the sequence of installation of the segments of a multi-branched hinged gate of the present invention.
Before the gate is transported to an installation site, the whole gate is longitudinally split into a left page 11, a right page 12 and a middle page, and the middle page is transversely split into a bottom section 13, a middle section 14 and a top section 15.
Referring to fig. 2, the installation sequence of each part of the slit gate is as follows: left side page 11, right side page 12, bottom link 13, middle link 14, and top link 15.
The split type gate can avoid the problems of too small gap between the gate and the gate wall and inconvenient installation, and can also solve the problem of difficult transportation caused by the overlarge whole volume and weight of the gate.
The lower end of the left side page 11 is provided with a first hinge hole 31, the lower end of the right side page 12 is provided with a first hinge hole 31, and the bottom block of the middle page is provided with four first hinge holes 31. The arrangement can ensure that the branch hinge holes are positioned on the same gate cutting block as much as possible on the basis of avoiding the problem of inconvenient installation due to too small gap between the gate 10 and the gate wall, thereby reducing the workload of coaxial adjustment of the first branch hinge hole 31.
When the axes of the first hinge holes 31 are adjusted, the superposition error between the axes of the first hinge holes 31 of the left side page 11 and the right side page 12 and the piano line can be adjusted to meet the design requirement, the superposition error between the axes of the first hinge holes 31 at the two ends of the bottom block 13 of the middle page and the piano line can be adjusted to meet the design requirement, and finally the superposition error between the axes of the first hinge holes 31 in the middle of the middle page and the piano line can be adjusted to meet the design requirement. The order of the left page 11 and the right page 12 is not required to be adjusted, and can be adjusted according to needs.
Because the bottom section 13 is provided with the four first supporting hinge holes 31, when one of the four first supporting hinge holes 31 is adjusted, the four first supporting hinge holes 31 can affect each other, so that the gate needs to be adjusted repeatedly until the coaxiality of the four first supporting hinge holes 31 on the bottom section 13 meets the design requirement, and then the bottom section 13, the left side page 11 and the right side page 12 of the gate are reinforced by spot welding according to the drawing reinforcing requirement.
After the distances between the axes of the first hinge holes 31 of the left side leaf 11, the right side leaf 12 and the bottom section 13 of the gate and the piano line are adjusted to meet the design requirements, spot welding reinforcement is carried out among the left side leaf 11, the right side leaf 12 and the bottom section 13. Thereby, deformation of the shutter 10 due to the operation in the subsequent mounting process can be reduced.
The support hinge seat 30 can be in place before the gate is hoisted, and can deviate to avoid interfering with the gate in hoisting, and support hinge installation is carried out after the bottom section is adjusted. The supporting hinge seat 30 can be temporarily fixed after being placed at a temporary position, and the temporary position can be shifted 200 mm and 300 mm to the outer river side from the set position. Because the pivot seat 30 has a certain inclination angle, the interference between the pivot seat 30 and the rear flange of the gate pivot plate can be avoided in the vertical hoisting process of the gate.
Fig. 3 to 5 schematically show a connection structure of a multi-hinge gate and a hinge support of the present invention.
Referring to fig. 3 to 5, six first hinge holes 31 are uniformly formed in the bottom of the gate 10, correspondingly, a hinge support 30 is disposed below each first hinge hole 31, and a second hinge hole 32 coaxial with the first hinge hole 31 is disposed on each hinge support 30.
After each pair of the first hinge hole 31 and the second hinge hole 32 is coaxially adjusted, a support hinge shaft 33 is inserted into the corresponding first hinge hole 31 and the second hinge hole 32, and a stop shaft plate 34 is mounted.
Only when the six first hinge holes 31 are coaxially aligned, the gate 10 can be smoothly turned.
After the shaft penetrating is completed, the middle section 14 and the top section 15 of the middle page are installed, and the middle section 14 and the top section 15 are connected with the bottom section 13, the left page 11 and the right page 12 through welding.
Fig. 6 schematically shows the relative positions of a plurality of hinged doors and piano wire cradles according to an embodiment of the present invention.
Referring to fig. 6, a reference point 45 is set on each of the first and second gate walls 21 and 22 where the gate 10 is to be installed as the first hinge hole 31 of the gate.
The gate is transported to the installation site and hoisted into position, and the fiducials 45 on the gate walls on both sides are connected by the piano wire 50 so that the piano wire 50 passes through each first hinge hole 31 of the gate without touching the edge of each first hinge hole 31. The diameter of the first hinge hole 31 is 400 mm.
The bracket 40 for lifting the piano wire 50 upwards is arranged in the middle of the two adjacent first hinge holes 31, the top of the bracket 40 is adjusted to be horizontal by matching with a level, and the top of the bracket 50 is adjusted to be consistent with the height of the reference point 45 by matching with a theodolite. The smoothness of the upper surface of the bracket 40 is required to be achieved
In the above, the piano wire can freely slide in the radial direction on the upper surface of the cradle 40.
The bracket 40 for supporting the piano wire is arranged at a certain distance, so that the problem that the drop amount of the middle position of the piano wire is too large when the piano wire is erected in a large span can be solved.
Six first hinge holes 31 are formed in the shutter 10, and a bracket 40 may be installed at a midpoint between every two first hinge holes 31 to assist in adjusting the height of a piano wire installed thereon, and a total of five brackets 40 are provided.
The piano wire sag calculation formula:
(x) sag (mm);
l is the distance (m) between two base points of the piano wire;
x is the distance (m) from the calculation site to the base point (the amount of sag reaches the maximum when X ═ 0.5L);
ρ is the weight per unit length of the piano wire, and 0.6mm of the piano wire ρ is 2.22(g/m)
m is a pulling force (30 kg is taken as the pulling force with the diameter of 0.6 mm);
0.99 is a correction value (when L <10m, the correction value is 1).
In this example, a 0.6mm diameter piano wire was used. According to the above formula, if the bracket 40 is not provided between the two reference points to support the piano wire: l is 26m, X is 0.5L;
the maximum sag f (26) max of the piano wire is 2.22 × 13 × 13/(2 × 30 × 0.99) 6.32(mm), which is not satisfactory.
Referring to fig. 6, a bracket 40 is disposed between every two first hinge holes 31, and a total of five brackets 40 are disposed, where a distance L between the two brackets is 5.2m, and X is 2.6.
The maximum sag f (5.2) max of the piano wire is 2.22 × 2.6 × 2.6/(2 × 30 × 1) is 0.25(mm), and the requirement can be satisfied.
In another embodiment, 0.6mm diameter piano wire is used. According to the above formula, if no support of the bracket 40 is provided between the two reference points: l is 25m, X is 0.5L;
the maximum sag f (25) max of the piano wire is 2.22 × 12.5 × 12.5/(2 × 30 × 0.99) 5.84(mm), which is not satisfactory.
If four brackets 40 are provided as the supporting points between the two reference points, the distance L between the adjacent two brackets is 5m, and X is 0.5L.
The maximum amount of sagging f (5) max of the piano wire is 2.22 × 2.5 × 2.5/(2 × 30 × 1) is 0.23(mm), and the requirement can be satisfied.

The longitudinal adjusting means 49 comprises a nut fixedly provided on the ear plate 44 and a screw adapted to the nut, an upper end of the screw being in contact with the lateral adjusting means 48, and the height of the lateral adjusting means 48 being adjustable. The lateral adjustment means 48 comprises a lateral bolt which passes through two elongated holes provided in the ear plates 44, respectively. A first guide wheel 41 is arranged in the middle of the transverse bolt, and a second guide wheel 42 hinged with the lug plates 44 is arranged between the two lug plates 44. Lateral adjustment device 48 can adjust the left-right position of first guide wheel 41.
The first guide wheel 41 is further provided with a pointer 43, a lateral adjusting device 48 and a longitudinal adjusting device 49, so that the end point of the pointer 43, the contact point of the piano wire 50 with the first guide wheel 41 and the reference point 45 on the second gate wall 22 are positioned on the same straight line.
After one end of the piano wire 50 is connected to a reference point on the first gate wall 21, the other end thereof goes around the first guide wheel 41 from top to bottom and then the second guide wheel 42 from top to bottom, and the tail end thereof is connected to a weight 60. Thus, the piano wire can always keep a certain tension.
Fig. 10 schematically shows an axis line adjusting method of a first hinge hole in a method of installing a multi-hinge gate according to an embodiment of the present invention.
When the axis of the first hinge hole 31 is adjusted, three or more probe points are uniformly taken on the circumference of each first hinge hole 31, the distance from each probe point to the piano wire 50 is measured, and the difference between the distances from all the probe points to the piano wire 50 by adjusting the position of the shutter 10 meets the design requirement. The measurement direction of the probing point on the circumference of the first hinge hole 31 where the distance to the piano wire is the largest is the axis deviation direction of the first hinge hole 31.
Referring to fig. 10, four probing points a1, a2, A3 and a4 are uniformly located on the circumference of one of the first hinge holes 31 of the shutter, a distance from a1 to the piano wire 50 is a1, a distance from a2 to the piano wire is a2, a distance from A3 to the piano wire is A3, and a distance from a4 to the piano wire is a 4. Where the length of A3 is obviously the longest, the direction of the line connecting the piano line and A3 is closest to the direction of the axis deviation of the first hinge hole 31. The shutter may be moved leftward so that the axis of the first hinge hole 31 is close to the piano line. The method is repeatedly and gradually adjusted, so that the difference of the distances from all the detection points of the first branch hinge holes 31 to the piano wire meets the design requirement.
