Description

Technical Field

[0001] This invention belongs to the field of ship lift maintenance technology, and specifically relates to a water seal punching clamping device and a water seal punching method. Background Technology

[0002] When replacing the C-shaped water seal of the sealing frame at the upper and lower gates of the ship lift, the old water seal must be removed first, and then the new water seal must be initially placed in position. The installation holes for the new water seal must then be drilled on-site according to the positions of the installation holes on the water seal mounting base. Because the water seal is placed on top of the water seal mounting base, it obstructs the installation holes on the base, making it impossible to accurately position the new water seal when drilling from top to bottom. Furthermore, due to site conditions and the limitations of the water seal mounting base structure, the new water seal cannot be drilled from bottom to top through the installation holes on the base. Currently, the common drilling method is for workers to visually estimate the approximate position of the holes on the water seal mounting base and then drill holes in the water seal based on experience. This method has the problem of deviation between the drilled hole position and the hole position on the water seal mounting base, making bolt installation of the water seal and the mounting base difficult and hindering the normal use of the water seal. Additionally, the deviation in the drilled hole position can cause the drill to directly hit the water seal mounting base, resulting in damage to both the drill and the mounting base. Summary of the Invention

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Reference Appendix Figure 1 - Appendix Figure 4 As a preferred embodiment of the present invention, this embodiment provides a water seal drilling clamping device, including a trapezoidal back plate 1, on which a plurality of locking screws 2 are provided, and at least two sets of D-shaped clamps 3 are connected to the trapezoidal back plate 1. The D-shaped clamp 3 includes a D-shaped clamp body 301, on which a sliding groove for sliding on the trapezoidal back plate 1 is constructed. The D-shaped clamp body 301 is slidably connected to the trapezoidal back plate 1, and the D-shaped clamp body 301 has two... The connecting end has a threaded connection to a screw 302 on one of the connecting ends. The upper cylinder of the D-shaped clamp body 301 has a threaded hole that mates with the screw 302. By rotating the screw 302, the distance between the bottom of the screw 302 and the D-shaped clamp body 301 can be adjusted, thereby clamping and fixing the water seal on the water seal mounting base. The screw 302 is used to clamp the water seal to be installed after rotation. A drilling device 4 is movably connected to the trapezoidal back plate 1. The drilling device 4 is located between the two sets of D-shaped clamps 3.

[0026] In the above embodiment, the drilling device 4 includes an L-shaped bracket 401 and a horizontal bracket 402 slidably connected to the L-shaped bracket 401. The L-shaped bracket 401 has a trapezoidal groove for connecting with the trapezoidal back plate 1. A positioning pin 401a is provided at the end of the L-shaped bracket 401. A drill mounting cylinder 402c is connected to the end of the horizontal bracket 402, and the drill mounting cylinder 402c is located directly above the positioning pin 401a. The horizontal bracket 402 consists of a T-shaped groove 402a, a connecting plate 402b, a drill mounting cylinder 402c, and a spring mounting cylinder 402d, and is used to place the drill 5 and guide the drill 5 to drill downwards.

[0027] In the above embodiment, the D-shaped clamp 3 is arranged on both sides of the drilling device 4, which can reliably clamp and fix the water seal B at the position to be drilled, and prevent the water seal B from sliding and misaligning with the water seal mounting base A during drilling.

[0028] In some embodiments, the L-shaped bracket 401 is provided with a spring mounting sleeve 401b, and the horizontal bracket 402 is provided with a spring mounting sleeve 402d. A spring 403 is fixedly connected between the two spring mounting sleeves. The spring 403 is installed in the spring mounting sleeves of the L-shaped bracket 401 and the horizontal bracket 402. When drilling, the worker pushes the horizontal bracket 402 downward with the electric drill 5 to compress the spring 403. After drilling is completed, the spring 403 resets, causing the electric drill 5 to move upward away from the drilling position.

[0029] In some preferred embodiments, to prevent the electric drill 5 from hitting the base plate of the L-shaped bracket 401 when drilling the water seal, a limiting block 401c is also fixedly connected to the L-shaped bracket 401. The limiting block 401c is used to limit the lowest position of the downward displacement of the horizontal bracket 402.

[0030] Refer to the attached diagram when using it. Figure 5 and attached Figure 6After the old water seal is removed and the new water seal is placed on the water seal mounting base, first, adjust the drilling device 4 and the D-shaped clamp 3 to the appropriate positions on the trapezoidal back plate 1 according to the actual site conditions. After adjusting the positions, tighten them with the locking screw 2. Then, align the positioning pin 401a with the mounting hole of the water seal mounting base to determine the installation position of the clamping drilling device. Then, rotate the screw 302 in the D-shaped clamp 3 to clamp the water seal and the water seal mounting base with the screw 302 and the D-shaped clamp body 301, and install the clamping drilling device in place with the water seal drilling position as the reference. Finally, the worker places the electric drill 5 in the electric drill mounting cylinder 402c and pushes the horizontal support 402 downward to drill the water seal. After drilling, the worker holds the electric drill 5 and removes the downward pressure on the horizontal support 402. The horizontal support 402 returns to its original position under the action of the spring 403, and the electric drill 5 leaves the drilling position, completing the water seal drilling. Because the clamping and punching device clamps and fixes the water seal and positions it accurately, each hole can be punched repeatedly on site to obtain a better punching effect.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
