Description

Technical Field

[0001] This invention relates to the field of lock valve construction, and in particular to a lock valve embedded positioning device and its construction method. Background Technology

[0002] During the construction of a ship lock, the installation and positioning of valve embedded parts is one of the core processes. Its accuracy directly affects the operational stability and sealing performance of the lock valves. The outer surface of the valve embedded part is used for valve rolling and for the installation of numerous valve seals. Therefore, the accuracy requirements for valve embedded parts are high. Currently, the industry generally uses an integrated steel frame support system for embedded part positioning. This system has the following core problems:

[0003] The integral steel frame is large in size and heavy in weight, requiring large hoisting equipment, which makes hoisting difficult and costly, and it has poor flexibility in operation in the narrow lock pit.

[0004] The steel frame and embedded parts are fixed by temporary welding. The welding process can easily cause deformation of the embedded parts, and the subsequent removal of the welding points requires extra time. At the same time, they cannot be reused for the next section of embedded parts support.

[0005] Therefore, there is an urgent need for a positioning solution for ship lock valve embedded parts that can reduce the difficulty of hoisting, improve positioning accuracy, and enable the reuse of supports, so as to solve the pain points of traditional technology. Summary of the Invention

[0018] The slider is used to connect with the middle guide rail and the side guide rail. The top of the connecting bracket is also equipped with a sling connection seat, which is connected to the lifting mechanism.

[0019] In the preferred embodiment, the lifting mechanism includes a crossbeam positioned on top of the central and side columns. A motor bracket is mounted on the crossbeam, and a winch is mounted on the motor bracket. A steel cable is positioned below the winch and connected to a sling connection seat.

[0064] In the preferred embodiment, the lifting mechanism 4 includes a crossbeam 307, which is positioned on top of the central column 1 and the side columns 2. A motor bracket 402 is also mounted on the crossbeam 307, and a winch 403 is mounted on the motor bracket 402.

[0066] The elongated hole 804 is used to connect the valve embedded part 8 to the next valve embedded part 8.

[0067] The construction method applied to the above-mentioned positioning device for embedded parts of a lock valve includes:

[0068] S1. Multiple bottom embedded parts 9 are embedded in the cast base according to the design position, which are used to install the middle column 1 and the side column 2 respectively.

[0069] S2. Use a crane to install the middle column 1 onto the bottom embedded part 9, and the side columns 2 are respectively arranged on both sides of the middle column 1;

[0070] S3. Hoist the slider 304 of the connector 3 from the top of the middle guide rail 102 and the side guide rail 206 and lower it to the lowest point.

[0071] S4. Install the lifting mechanism 4 on the top of the middle column 1 and the side column 2. Connect the steel cable 404 in the lifting mechanism 4 to the sling connection seat 305. Start the winch 403 to lift the connector 3 to a suitable position for auxiliary support.

[0072] S5. Hoist the valve embedded part 8 to one side of the embedded part bracket 202, and attach the first side plate 801 and the second side plate 802 to the right angle surface of the embedded part bracket 202.

[0073] S6. Activate one side of the telescopic cylinder 204 to make the permanent magnet attract the valve embedded part 8, and then slowly retract the telescopic cylinder 204 so that the first side plate 801 of the valve embedded part 8 fits against one side of the embedded part bracket 202.

[0074] S7. Repeat step S6 until all valve embedded parts 8 are installed. After the valve embedded parts 8 are installed, there is a reserved gap 7 between the end template 5 and the waterway template. The reserved gap 7 is used to install the splicing template of the corresponding width.

[0075] S8. Weld the splicing template to both ends of the valve embedded part 8. After the welding is completed, the construction of the lock embedded part positioning is completed.

[0076] Example 2

[0077] Further explanation in conjunction with Example 1, such as Figure 1-15 The detailed construction method for applying the structure shown to the above-mentioned lock valve embedded positioning device is as follows:

[0078] Verify all equipment in advance: test the smoothness of extension and retraction of the telescopic cylinder 204 to ensure there is no jamming; check the braking performance of the winch 403, and conduct no-load and full-load test runs to ensure that the steel cable 404 is retracted and extended smoothly; verify the adsorption reliability of the permanent magnet to avoid subsequent adsorption failure.

[0079] Rust removal and anti-rust paint are applied to the connecting seats 103 and 207 of standard section 101 and standard section 201; grease is applied to the surface of the middle guide rail 102 and the side guide rail 206 to reduce subsequent sliding resistance; prefabrication of splicing templates is carried out to ensure that the edges of the templates are smooth and can match the width of the reserved gap 7.

[0080] S1: Install bottom embedded part 9

[0081] On the already poured concrete base of the lock pit (the base strength must meet the standard), mark the installation positions of the middle column 1 and the side columns 2 according to the design drawings. Use a total station to locate and delineate the embedding area of ​​the bottom embedded part 9, place the bottom embedded part 9 into the preset groove, adjust the level, pour concrete to fix it, and cure until the strength meets the standard. After completion, check the positional accuracy of the reserved holes on the bottom embedded part 9 to ensure that they are compatible with the connecting seat 103 and the connecting seat 207.

[0082] S2: Install the central column 1 and the side columns 2

[0083] Use a crane to hoist standard section 101, align the connecting seat 103 of the bottom standard section 101 with the reserved hole of the bottom embedded part 9, and insert high-strength bolts for fixation. After each standard section 101 is assembled, check the verticality with a total station and make fine adjustments using the bottom bolts. Install standard section 207 of the side columns 2 according to the same procedure, ensuring that the distance between the two side columns 2 and the middle column 1 meets the design requirements.

[0084] After the columns are spliced ​​to the designed height, the top elevation of the middle column 1 and the side column 2 is measured. By grinding the contact surfaces of the connecting seat 103 and the connecting seat 207, the top surface height is ensured to be consistent, providing a horizontal reference for the installation of the lifting mechanism 4.

[0085] S3: Install connector 3

[0086] On the ground, insert the slider 304 into the slider slot 303 of the connecting bracket 301, check the elasticity of the spring 307, ensure that the slider 304 can slide flexibly along the slider slot 303, and apply grease to reduce wear.

[0087] Using a crane, hoist the assembled connector 3 (including the connecting bracket 301, connecting rod 302, and slot beam 306) between the central column 1 and the side column 2, aligning the slider 304 with the top entrance of the central guide rail 102 and the side guide rail 206, and slowly lower it. During the lowering process, use a pry bar to assist in adjustment, ensuring that the slider 304 is fully embedded in the guide rail without any jamming, and finally lower the connector 3 to its lowest point.

[0088] S4: Installation and commissioning of lifting mechanism 4

[0089] Hoist the crossbeam 401 to the top of the middle column 1 and the side column 2, and fix it with the top bolts of the connecting seat 103 and the connecting seat 207. Check the levelness of the crossbeam 401 to ensure that it meets the installation requirements.

[0090] A winch 403 is fixed on the motor bracket 402 of the crossbeam 401, and a steel cable 404 is threaded through it. The steel cable 404 is reliably connected to the sling connection seat 305 of the connector 3 through the fixed pulley under the crossbeam 401, and a rope clamp is used to ensure stability.

[0091] Start the winch 403, slowly raise the connector 3 to the specified height and then pause. Check the fit between the slider 304 and the guide rail and the tension of the steel cable 404. After confirming that there are no problems, lower the connector 3 to the initial position.

[0092] S5: Lifting and positioning valve embedded parts 8

[0093] Temporary lifting lugs are welded onto the support rib plate 803 of the valve embedded part 8, and a suitable crane is selected for lifting.

[0094] The valve embedded part 8 is hoisted to the outside of the embedded part bracket 202. The angle is finely adjusted by manually pulling the rope so that the first side plate 801 and the second side plate 802 are close to the right angle sides of the embedded part bracket 202, ensuring that the orientation of the docking elongated hole 804 of the support rib plate 803 meets the subsequent connection requirements.

[0095] S6: Telescopic hydraulic cylinder 204 fixed valve embedded part 8

[0096] Start the telescopic cylinder 204 on the side of the first side plate 801 corresponding to the embedded part bracket 202, so that the permanent magnet at the top of the piston rod extends along the fitting through hole 205 and approaches the first side plate 801. After turning on the power of the permanent magnet to ensure that it is firmly attracted, control the telescopic cylinder 204 to slowly retract until the first side plate 801 is in contact with the embedded part bracket 202.

[0097] Start the telescopic cylinder 204 on the side of the second side plate 802 corresponding to the embedded part bracket 202, and repeat the above adsorption and retraction operation to make the second side plate 802 fit with the embedded part bracket 202. At the same time, check the perpendicularity of the first side plate 801 and the second side plate 802 to ensure that it meets the design standards.

[0098] Maintain stable working pressure for all telescopic cylinders 204, and mark the piston rod extension length on the cylinder body for easy recalibration later.

[0099] S7: Reserved gap 7 and installation of splicing template

[0100] Check the reserved gap 7 between the valve embedded part 8 and the end template 5 and the waterway template 6. If there is a deviation, correct it by fine-tuning the telescopic cylinder 204.

[0101] Embed the prefabricated splicing template into the reserved gap 7, so that one side of the template is close to the end of the valve embedded part 8, and the other side is aligned with the end template 5 or waterway template 6. Use intermittent welding to fix the splicing template to the valve embedded part 8. After welding, remove the welding slag and check the weld quality to ensure that there is no false welding or slag inclusion.

[0102] S8: Overall inspection and construction completed

[0103] Use a total station to re-measure the axis and top surface elevation of the valve embedded part 8, check whether the support position of the connector 3 is reasonable, confirm that the pressure of the telescopic cylinder 204 is stable and the permanent magnet adsorption is reliable, and all indicators must meet the design requirements.
