Description

Technical Field

[0001] The present invention belongs to tooling, and particularly relates to a high-precision track adjustment auxiliary tooling. Background Art

[0002] The acceptance of nuclear power plant track installation includes requirements such as straightness, levelness, and allowable deviation range of track joints. With the high standards and strict requirements of nuclear power standards, the adjustment accuracy of nuclear power tracks has been gradually improved.

[0003]

[0004] At home and abroad, the adjustment of crane tracks is to fix the tracks through track pressing plates, and track straightness adjustment devices are set on the left and right sides for adjustment. The straightness of the tracks is measured by a total station, and adjusted by adjusting the jackscrews on the left and right sides. The elevation of the tracks is commonly measured by a level, and the tracks are adjusted by adding cushion blocks under the tracks. The span of the tracks can be checked by a steel tape or an infrared measuring instrument. There are many measuring instruments, and many tracks are not equipped with track straightness adjustment devices, and can only be adjusted left and right by a hammer or a crowbar, resulting in large adjustment errors.

[0005] The existing track level adjustment tooling (CN204135120U) uses adjusting jackscrews to achieve left and right adjustment of the tracks, ensuring the final installation accuracy of the tracks; and in combination with the method of adjusting the straightness of the tracks, in China, a vernier caliper and a total station are usually used for combined adjustment. First, each 2m of the track is evenly divided into a measurement point. The construction personnel fix the vernier caliper above the track at the measurement point position for track centering, and the surveyor uses a total station for measurement; the human operation error is large, and each point needs to be repeatedly measured and adjusted, resulting in a large construction intensity for the personnel; for the straightness adjustment, a wooden mallet and a crowbar are used to move the track left and right, and the offset amount cannot be controlled; for the track level adjustment, a crowbar is used to lift and cushion blocks are added under the track, which is likely to cause the track position to shift. The existing measurement methods have the following disadvantages: (1) large construction intensity; (2) many human operation errors; (3) unable to simultaneously achieve up, down, left, and right direction adjustments; (4) unable to achieve high-precision adjustment. Summary of the Invention

[0006] The content of the present invention is to provide a high-precision track adjustment auxiliary tooling in view of the defects of the prior art.

[0007] The present invention is implemented as follows: A high-precision track adjustment auxiliary tooling, which includes a lifting tooling arranged on the track, a ball prism tooling for carrying the ball prism, a prism tooling for carrying the prism, a straightness tooling for measuring straightness, and a target piece tooling for carrying the target piece. The target piece tooling is arranged at the central position of the track. The lifting tooling is arranged on one side of the target piece tooling, and the ball prism tooling, the prism tooling, and the straightness tooling are sequentially arranged on the other side of the target piece tooling. Among them, the ball prism tooling is the closest to the target piece tooling, and the straightness tooling is the farthest from the target piece tooling.

[0008] A high-precision track adjustment auxiliary tooling as described above, wherein the lifting tooling includes a portal frame, a jackscrew and a lifting end are arranged on the top surface of the portal frame. There are two lifting ends in total, and one jackscrew is arranged. The jackscrew and the lifting end longitudinally penetrate the top surface of the portal frame. Corresponding through slots are opened on the two side walls of the portal frame, and a screw rod and a nut are arranged in each through slot. The screw rods and nuts on both sides form a clamping device.

[0009] A high-precision track adjustment auxiliary tooling as described above, wherein the ball prism tooling includes a cuboid upper support plate, a lower cylinder is arranged below the upper support plate. There are two lower cylinders, which are evenly arranged below the upper support plate. The lower cylinder is fixedly connected to the upper support plate by bolts. An upper handle is arranged on the upper part of the upper support plate, and a spirit level is also arranged on the upper part of the upper support plate.

[0010] A high-precision track adjustment auxiliary tooling as described above, wherein the prism tooling includes an upper support plate with a "concave" cross-section. A screw rod penetrating the upper support plate is arranged on the side wall of the upper support plate, and the screw rod is fixed on the upper support plate by a nut.

[0011] A high-precision track adjustment auxiliary tooling as described above, wherein the straightness tooling includes a track pressing plate bottom plate, a self-made pressing plate is arranged on the track pressing plate bottom plate. The track pressing plate bottom plate and the self-made pressing plate are fixedly connected by a pressing plate bolt and a nut. A gasket is also arranged between the pressing plate bolt and the self-made pressing plate. The self-made pressing plate is provided with an "L"-shaped protrusion, and a bolt is arranged at this protrusion position, and a nut is arranged on the bolt.

[0012] A high-precision track adjustment auxiliary tooling as described above, wherein the target piece tooling includes an L-shaped steel, and a target piece is arranged on the L-shaped steel.

[0014] A high-precision track adjustment auxiliary tooling as described above, wherein there are multiple track pressing plates, which are evenly arranged on the track.

[0015] The remarkable effects of the present invention are as follows: (1) The tooling can achieve the adjustment of the track height difference and levelness, with low requirements for personnel operation. Compared with the measurement method using vernier calipers, the fixing and alignment operations of the calipers are reduced. The tooling fixes the track for adjustment, and the track position is locked, so the track cannot move. The personnel operation is simple. Since the track installation accuracy is high and fine adjustment is required repeatedly, the construction time is long. Using this tooling can effectively shorten the construction time, reduce the personnel input, and lower the work intensity of construction workers;

[0016] (2) After the tooling is in place, it is directly fixed, reducing the human operation error, improving the installation quality while reducing the measurement time;

[0017] (3) The tooling can simultaneously achieve the adjustment of the track in four directions: up, down, left, and right, for multi-directional measurement;

[0018] (4) By controlling the number of rotation turns of the bolts, the feed amounts of the track in the up, down, left, and right directions can be accurately controlled, realizing fine adjustment and precise adjustment operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] A high-precision track adjustment auxiliary tooling, which consists of a screw, a nut and an upper support plate. The threaded holes on the upper support plate are used to fix the prism. The side nut is welded to the side support plate. The level bubble on the prism can judge whether the tooling is level. It realizes automatic centering and alignment by closely adhering to the track on one side. The side bolts fix the tooling and cooperate with the total station to measure the straightness. The difference in the straightness of the two tracks is the track span. The prism tooling needs to be used in cooperation with the prism and the total station for measurement;

[0028] The ball prism tooling, which consists of a lower cylinder, an upper handle, an upper support plate, a level bubble and bolts. The upper support plate and the upper handle are positioned through the holes in the top plate and welded and fixed after the position is confirmed. The lower cylinder and the bolts are fixed on the upper support plate, and the level bubble is installed. It realizes track centering by rotation. The ball prism tooling needs to be used in cooperation with the ball prism and the total station;

[0029] The straightness tooling, which consists of a self-made pressing plate, nuts and bolts. The nuts are welded on the smooth holes of the pressing plate, and the bolts are fixed in the nuts. Before adjustment, the bolts, washers and nuts supporting the track pressing plate need to be assembled with the tooling. The straightness tooling is located on both sides of the track. Use a wrench to screw the bolts laterally into the top support track, and the track moves under force to realize left and right adjustment;

[0030] The lifting tooling, which consists of a gantry, a jackscrew, a screw, a nut and a lifting end. Before track adjustment, a lifting tooling is arranged and welded and temporarily fixed at the front and rear ends of the track end. The gantry is welded and fixed by 3 plates, and the side nuts are spot-welded and fixed. The up and down movement of the jackscrew is realized by adjusting the position of the nut. Use a wrench to screw the bolts laterally into the track to realize the lateral push of the track. The track is pressed tightly by the jackscrew pressing down. The lifting end is supported on the gantry by rotating the nut to limit the position, realizing the up and down movement of the track. In summary, the lifting tooling can realize the movement of the track in four directions: up, down, left and right;

[0031] The target plate tooling, which consists of an L-shaped steel and a target plate. The center of the L-shaped target plate corresponds to the center of the track. The target plate is pasted at the center of the L-shaped target plate. At the measurement point, one side of the L-shaped steel is closely adhered to the side of the track, and the center position of the target plate is checked to be located at the center of the track. After coincidence, it is used in cooperation with the total station for track straightness measurement and adjustment.

[0032] Tooling Introduction

[0033] Aiming at the track technical requirements, a high-precision track adjustment auxiliary tooling design is carried out, mainly including: prism tooling, ball prism tooling, straightness tooling, lifting tooling and target plate tooling.

[0034] Prism tooling: The center of the hole corresponds to the center of the track. The left end is closely adhered to the track. There is a water droplet on the prism. The prism is leveled by adjusting the jackscrew through the prism tooling to realize centering and alignment.

[0035] Ball prism tooling: A rotating tooling. The lower cylinder is jammed with the track, and the ball prism is automatically centered to achieve prism alignment. The levelness of the tooling itself can be checked through the horizontal bubble at the center of the upper surface of the tooling.

[0036] Straightness tooling: The bottom fixing ring is a provided item. The tooling consists of a fixed support and bolts. Before use, place the straightness adjustment tool on the fixing ring and adjust the straightness of the track through the setscrew.

[0037] Lifting tooling: The tooling realizes track lifting through two pawls, the middle bolt realizes track clamping, and the adjusting setscrews on both left and right sides realize the adjustment of track straightness.

[0038] Target piece tooling: For the automatic manipulator of the spent fuel storage pool, the top section of the guide rail is 60mm, and the top section of the load-bearing rail is 70mm. Two target piece toolings need to be prepared. Due to the need to frequently change positions during on-site construction, the guide rail and load-bearing rail target piece toolings are not integrated. Press the L-shaped tooling tightly against the side and top of the track, and the center of the target piece automatically aligns with the center of the track. The structural principle can be modified for matching according to different top sections of the track for application.

[0039] This application can achieve the following effects:

[0040] 1. Reduce the construction intensity of personnel. The tooling measurement at the same point saves 1 minute compared with manual measurement.

[0041] 2. Reduce the operation error of personnel and optimize the fixing and alignment operations of the caliper.

[0042] 3. Multi-directional adjustment to achieve adjustment in the up, down, left, and right directions.

[0043] 4. High-precision adjustment. Control the movement offset according to the number of turns of the bolt screwed in. The tooling fixes the track and the track cannot move.
