Problems solved by technology

[0005] On the one hand, the index line of the rack must be drawn manually before the measurement, but the efficiency of manual marking is low and the error is large, so the index line cannot be determined accurately and quickly, so that the measurement efficiency of the tooth thickness is low and the error is large. Big
On the other hand, due to the complicated process of manual scribing and the need to use a tooth thickness caliper to measure after scribing, the existing tooth thickness measurement process is relatively complicated.

Embodiment 1

[0031] In order to facilitate the description of the embodiment, the following briefly introduces the leg rack. Such as figure 1 As shown, the rack 1 includes a rack plate 11 and a pair of menisci 12 symmetrically arranged on the top surface and the bottom surface of the rack plate 11 . A plurality of teeth 13 are provided on the left side and the right side of the rack plate 11 , and tooth grooves 14 are formed between two adjacent teeth 13 . The inclined surface of the tooth 13 forming the tooth groove 14 is the tooth surface 15 , the top of the tooth 13 is the tooth crest 16 , and the two parallel side surfaces of the tooth 13 are the tooth sides 17 . Such as figure 2 As shown, the addendum height H1 is the distance between the index line L1 of the rack 1 and the addendum line L2. The tooth thickness S is the distance between two intersection points P1 and P2 where the index line L1 intersects the tooth surfaces 15 on both sides of the tooth 13 .

Embodiment 2

[0043] The embodiment of the present invention provides a method for measuring the tooth thickness of the leg rack, see Image 6 , the method includes:

[0044] Step 301: Insert the tooth surface support plate of the tooth thickness measuring tool into the tooth groove of the rack and abut against the tooth surface of the rack;

[0045] Step 302: Determine the intersection line of the bottom surface of the tooth side support plate and the plane parallel to the tooth side support plate, so as to determine the index line of the rack;

[0046] Step 303: According to the determined graduation line, use the scale on the tooth side backing plate to read the size of the tooth thickness.

[0047] The beneficial effects brought by the embodiments of the present invention are: on the one hand, since the height of the tooth surface abutment plate in the direction perpendicular to the tooth top abutment plate is equal to the height of the tooth top of the rack, that is, the top surface o...

Abstract

The invention discloses a spud leg rack thickness measuring tool and measuring method and belongs to the field of ocean drilling platform lifting systems. The tool includes a rack top backup plate, a rack surface backup plate and a rack side backup plate. The rack top backup plate is in fixed connection to one end of the rack side backup plate and is perpendicular to the one end of the rack side backup plate. The other end of the rack side backup plate is provided with scales. The rack surface backup plate is arranged between the rack side backup plate and the rack top backup plate and is in separate fixed connection to the rack side backup plate and the rack top backup plate. The rack surface backup plate has a height in the direction perpendicular to the rack top backup plate higher than a rack top of a spud leg. The method includes the following steps: attaching closely the rack top backup plate of the tool to the rack surface of the spud leg; determining the reference line of the spud leg; based on the reference line, using the scale on the rack side backup plate to read the rack thickness. According to the invention, the reference line can be rapidly and accurately determined through the bottom surface of the rack surface backup plate, so that the efficiency is increased and the measuring is easy to operate.

Description

technical field [0001] The invention relates to the field of offshore platform lifting systems, in particular to a tool for measuring the tooth thickness of a leg rack. Background technique [0002] The lifting system is one of the key equipment of the jack-up offshore platform. The lifting system is installed at the junction of the main body of the platform and the legs, and mainly realizes the relative movement of the main body of the platform and the legs up and down, or fixes the main body of the platform at a certain position of the legs. The rack and pinion lifting system is widely used in various jack-up offshore platforms due to its advantages of fast lifting speed and high degree of automation. The rack and pinion lifting system has very strict precision requirements for the size of the leg rack. The tooth thickness of the leg rack refers to the distance between the index line of the rack and the two intersection points where the tooth surfaces on both sides of an...
