Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary positioning of dampers, and in particular relates to an auxiliary positioning and installation tool for dampers. Background Art

[0002] like Figure 3 As shown in the figure, when the bridge is subjected to earthquake vibration, the dampers symmetrically located between the support frame and the cables can effectively absorb and disperse the vibration energy, prevent the bridge from excessive vibration and deformation, and protect the internal structure and facilities of the bridge from damage. However, the installation of dampers currently has the following defects: 1) The lengths of the dampers on the left and right sides are inconsistent and there is a deviation. If the deviation exceeds 5mm, it will cause uneven force on the left and right sides, and cannot absorb and disperse the vibration energy well; 2) As shown in the figure, the dampers on the left and right sides are symmetrically located between the support frame and the cables, and can effectively absorb and disperse the vibration energy, so as to avoid excessive vibration and deformation of the bridge .... Figure 4 As shown, it is impossible to accurately ensure that the damper cable clamp and the inclined cable are in a perpendicular position to each other by naked eyes, and it is also impossible to ensure that the damper axis is perpendicular to the inclined cable, resulting in twisting of the connecting pins at both ends of the damper during installation, thereby affecting the function of the damper. Utility Model Content

[0003] The utility model aims to provide a damper auxiliary positioning and installation tool, which assists positioning and is easy to operate. It solves the problems that the inconsistent lengths of the dampers on the left and right sides of the existing left and right sides lead to uneven forces on the left and right sides, and the axis of the damper is not perpendicular to the inclined cable, which leads to the twisting of the connecting pins at both ends of the damper and affects the action of the damper.

[0004] To this end, the technical solution adopted by the utility model is: a damper auxiliary positioning installation tool, including an auxiliary positioning main frame, a cable clamp cover matching the top of the auxiliary positioning main frame and a supporting frame pipe clamp cover matching the top pipe clamp of the supporting frame. The bottom of the auxiliary positioning main frame is provided with a transverse round tube for the supporting frame pipe clamp cover and the upper and lower clamps of the supporting frame top pipe clamp to be installed. The top of the auxiliary positioning main frame is provided with a cable clamp matching the cable clamp cover, and clamps the outer periphery of the cable in the vertical direction of the center line of the cable. The center line of the supporting frame is perpendicular to the horizontal plane, and the center line of the supporting frame, the center line of the cable and the center line of the auxiliary positioning main frame are coplanar. The length of the transverse round tube matches the clamp length of the supporting frame pipe clamp cover and the top pipe clamp of the supporting frame.

[0005] As a preferred embodiment of the above scheme, the cable clamp cover and the cable clamp as a whole are both bilaterally symmetrical structures with a triangular bend in the middle and left and right ends flattened. The structural design is reasonable, suitable for clamping cables of various diameters, flexible to use, and wide in application.

[0006] Further preferably, an "n"-shaped frame is provided at the bottom of the auxiliary positioning main frame, and the transverse round tube is transversely installed in an integrated manner at the open end of the "n"-shaped frame, and a through hole is left for the support frame pipe clamp cover to pass through, and the structural design is reasonable.

[0007] Further preferably, the middle portion of the auxiliary positioning main frame is a hollow square tube structure, which is simple and reasonable to operate.

[0008] Further preferably, the support frame is welded and installed on the top surface of the embedded steel plate, and the welding is firm.

[0009] Further preferably, the support frame pipe clamp cover and the support frame top pipe clamp are fixed by bolts, which are firmly fixed and easy to operate.

[0010] Further preferably, the left and right flattened ends of the cable clamp and the cable clamp cover are provided with two mounting holes at intervals, and are equipped with a screw rod which passes through the mounting holes and is fixed by tightening nuts at the ends, so that the fixing is firm and the operation is simple.

[0011] Beneficial effects of the utility model:

[0012] (1) Compared with the existing left and right dampers with inconsistent lengths, which leads to unbalanced force on the left and right sides, this solution makes the center line of the installed support frame perpendicular to the vertical projection line of the center line of the cable, so as to ensure that the dampers installed later can be installed symmetrically on both sides of the support frame. Only in this way can the length of the dampers be basically consistent, with an error of less than 5mm, and the effect of the later dampers in absorbing and dispersing vibration energy be guaranteed. The structural design is ingenious.

[0013] (2) Compared with the situation that the axis of the damper is not perpendicular to the inclined cable, which causes the connecting pins at both ends of the damper to twist and become deformed, thus affecting the function of the damper, this solution leaves a mark on the outer wall of the cable corresponding to the upper edge or lower edge of the cable clamp for positioning when the damper clamp is installed later. When the damper is installed later, the edge of the cable clamp is aligned with the mark drawn previously, so that the installation position of the damper clamp can be accurately located, thereby ensuring that the axis of the damper can be perpendicular to the inclined cable and that the connecting pins at both ends of the damper are not twisted and deformed. Therefore, the use effect of the damper can be guaranteed to the greatest extent, the failure of the damper can be avoided, and safety hazards can be effectively eliminated.

[0014] In summary, the invention has the advantages that the damper can be installed symmetrically on the left and right, the structural design is ingenious, the axis of the damper can be perpendicular to the inclined cable, and potential safety hazards are eliminated.

[0019] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:

[0020] Combination Figure 1 — Figure 2 As shown, a damper auxiliary positioning installation tool is composed of an auxiliary positioning main frame 3, a cable clamp cover 4 matched with the top of the auxiliary positioning main frame 3, and a support frame pipe clamp cover 5 matched with the top pipe clamp of the support frame 1.

[0021] The support frame 1 is measured with a level ruler or plumb bob to make it perpendicular to the horizontal plane.

[0022] The support frame 1 is welded and installed on the top surface of the embedded steel plate.

[0023] The center line of the support frame 1 is perpendicular to the horizontal plane, and the center line of the support frame 1, the center line of the cable 2, and the center line of the auxiliary positioning main frame 3 are coplanar.

[0024] A transverse round tube 32 is provided at the bottom of the auxiliary positioning main frame 3 for the support frame pipe clamp cover 5 and the upper and lower clamps of the support frame 1 top pipe clamp to be installed.

[0025] An "n"-shaped frame 33 is provided at the bottom of the auxiliary positioning main frame 3.

[0026] The middle part of the auxiliary positioning main frame 3 is a hollow square tube structure.

[0027] The transverse circular tube 32 is installed in an integral manner transversely at the open end of the "n"-shaped frame 33, and a through hole is left for the support frame pipe clamp cover 5 to pass through.

[0028] The length of the transverse circular tube 32 matches the length of the support frame pipe clamp cover 5 and the clamping hoop of the top pipe clamp of the support frame 1 .

[0029] A cable clamp 31 matching the cable clamp cover 4 is provided on the top of the auxiliary positioning main frame 3 and clamps the outer periphery of the cable 2 in a vertical direction along the center line of the cable 2 .

[0030] On the outer wall of the cable 2 corresponding to the upper edge or the lower edge of the cable clamp 31, there is a mark for positioning when the damper cable clamp is installed later.

[0031] Two mounting holes are arranged at intervals on the left and right flattened ends of the cable clamp 31 and the cable clamp cover 4, and are equipped with screw rods that penetrate the mounting holes and are fixed by tightening nuts at the ends.

[0032] The cable clamp cover 4 and the cable clamp 31 are arranged in mirror symmetry.

[0033] The cable clamp cover 4 and the cable clamp 31 are both symmetrical structures with a central triangular bend and left and right ends flattened.

[0034] The support frame pipe clamp cover 5 and the top pipe clamp of the support frame 1 are fixed by bolts.

[0035] Positioning of the support frame 1: first insert the pipe clamp at the top of the support frame 1 into the horizontal round pipe 32, cover the pipe clamp cover 5 of the support frame, and fix it with M12*60 bolts;

[0036] Clamp the cable 31 on the lower surface of the inclined cable, cover the cable clamp cover 4, insert the M12 screw, screw nuts on both ends of the screw, tighten the nuts slightly to ensure that the cable clamp 31 can be adjusted up and down, and then place the bottom surface of the support frame 1 on the top surface of the embedded steel plate.

[0037] Adjust the position to ensure the following requirements:

[0038] A. The center of the bottom surface of the support frame 1 is on the vertical projection line of the center line of the cable 2;

[0039] B. The support frame 1 is vertical to the horizontal plane, and it can be ensured by measuring with a level ruler or plumb bob;

[0040] C. Ensure that the axis of the auxiliary positioning main frame 3 is perpendicular to the center line of the cable 2 by measuring with a protractor.

[0041] After the position is adjusted, tighten the M12 screw nut and mark along the upper edge of the cable clamp 31 with a marker. The mark is used for positioning when installing the damper cable clamp later.

[0042] Fix the bottom surface of the support frame and the embedded steel plate with electric welding first, and then fully weld them.

[0043] The weld is a full circumferential weld, the effective height of the weld is greater than 7mm, and the weld has no missing welds or pores to prevent water seepage and rust in the support frame steel pipe. Attention should be paid to the process during welding to prevent the support frame 1 from being deformed due to uneven heating during welding.

[0044] Install the damper structure as follows:

[0045] Insert the upper bracket of the damper overall structure into the pipe clamp on the top surface of the support frame 1. The pipe clamp is clamped in the two limit screws of the upper bracket. Cover the pipe clamp cover, put on 4 M12×60 bolt assemblies, and do not tighten the nuts temporarily to ensure that the steel pipe of the upper bracket can rotate in the pipe clamp.

[0046] Note: The 4 pins should be inserted from top to bottom, with the cotter pin at the bottom.

[0047] Stick the inner wall of the lower cable clamp of the damper overall structure to the lower surface of the cable 2, align the upper edge of the damper cable clamp with the mark drawn before, then cover the damper cable clamp cover, and insert 4 M12×60 bolts. The nuts cannot be tightened at this time to ensure that the damper cable clamp can rotate.

[0048] Adjust the position of the cable clip to ensure the following requirements:

[0049] A. Align the upper edge of the damper cable clamp with the mark drawn previously;

[0050] B. The two dampers are arranged symmetrically with respect to the vertical projection plane of the cable, and the center distance between the damper pins is 490mm. If the deviation is found to exceed ±5mm, it is necessary to adjust and reset by pulling and pressing the damper.

[0051] C. The center lines of the two dampers are perpendicular to the inclined cables, and there is no twisting or distortion between the connecting earrings, that is, the gaps on both sides of the connecting earrings are equal.

[0052] After adjusting the position, tighten the damper cable clamp nut.

[0053] Finally, remove the welding slag and grind the weld.

[0054] All welds, damaged areas of damper paint, and bolted connections must be re-coated with heavy anti-corrosion paint in accordance with the painting process.
