Description

Technical Field

[0001] The utility model relates to the technical field of ship lifts, and more particularly to a pre-drilling tool for water seal installation holes of a ship lift docking sealing device. Background Art

[0002] When the ship-carrying box of the vertical ship lift is docked with the upstream and downstream working gates, a docking sealing device is generally required to seal the docking gap. The docking sealing device is often set on the working gate of the gate or at the end of the ship-carrying box. Its structure generally includes a U-shaped docking sealing frame, which is driven by multiple hydraulic cylinders and can be extended or retracted. A water seal with a C-shaped cross-section and a water seal with an L-shaped cross-section are often set on the docking sealing frame. The C-type water seal is used to seal the gap between the docking sealing frame and the fixed installation end; the L-type water seal is used to press against the sealing surface on the opposite side to form a seal after the docking sealing frame is extended. The water seal material is usually cloth-reinforced rubber.

[0003] C-type and L-type water seals are usually installed by bolts and pressure plates. Due to the large number of bolt holes, in order to ensure that the hole positions match the site, new water seals are usually not equipped with installation holes when leaving the factory, so holes need to be matched on site. Generally, when installing a new water seal, first put the water seal into the installation gap and adjust the position, then use C-type clamps and other clamps to temporarily fix the water seal to the metal structure, then drill holes for the water seal using the installation holes on the metal structure, and finally install the bolts and remove the clamps.

[0004] During the long-term operation of the ship lift, the C-type water seal may crack due to aging or be punctured by hard objects such as branches, resulting in an emergency of sudden large-scale water leakage. At this time, the ship lift generally needs to stop sailing to repair or replace the water seal. At present, the on-site hole matching method used for the new water seal generally takes several days, which accounts for a large proportion of the entire water seal replacement period, which is not conducive to the rapid resumption of navigation of the ship lift to reduce the negative impact of the suspension on the social economy.

[0040] The following will be combined Figure 1-Figure 14 , a pre-drilling tool for water seal installation holes of a ship lift docking sealing device involved in the embodiment of the present application is described in detail. It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation of the present application.

[0041] Embodiment 1:

[0042] See also Figure 1-Figure 14 As shown, a pre-drilling tool for the water seal mounting holes of a ship lift docking sealing device includes a plurality of support modules 1, and the support modules are based on a support frame 1a. The lifting frame of the support module can be driven by other lifting mechanisms such as hydraulic cylinders and jacks. A C-shaped support plate 1b adapted to the cross-section of the C-shaped water seal 13 is provided on the support frame, and an arc-shaped support plate 1c is provided on each side of the arc at the bottom. An inner mounting plate 1d is provided on the top of one side wall of the C-shaped support plate, and two slide rails 1e are provided on the outer side of the other side wall. The lifting frame 1f is installed on the slide rail through a plurality of sliders 1g on both sides, an outer mounting plate 1h is provided on the top, and an electric push rod 1i is provided between the bottom and the support frame, and the electric push rod can drive the lifting frame to extend ( Figure 2 ) or retract ( Figure 1 ). Two fixed wheels 1j and two universal wheels 1k are provided at the bottom of the support frame for moving the support module, and four foot cups 1l are provided for adjusting the height and levelness of the support module.

[0043] like Figures 3 to 8 As shown, multiple support modules 1 are arranged in a U-shape on a horizontal basis in accordance with the unfolded state of the water seal, wherein the side provided with the lifting frame faces the outside of the U-shape. Multiple outer straight-segment perforated plates 2 and two outer arc-segment perforated plates 3 are bolted to the outer C-shaped clamp mounting plate 1h of each support module to form the outer perforated frame of the tooling; multiple inner straight-segment perforated plates 4 and two inner arc-segment perforated plates 5 are bolted to the inner mounting plate 1d of each support module to form the inner perforated frame of the tooling.

[0044] The gap between the inner and outer hole frames constitutes the installation space of the water seal, and the size of this space is consistent with the actual installation size of the water seal on site. The cross-section of each hole plate is L-shaped, which can increase the rigidity of the structure. Each hole plate is provided with a plurality of drill holes, the hole diameter is consistent with the bolt hole on site, and the hole position is consistent with the relative position of the actual bolt hole on site of the water seal. Each hole plate of the inner and outer hole frames is numbered. After each hole plate is installed on the support module according to the number, each drill hole corresponds to the actual hole position on site of the water seal. The upper end surface of the L-shaped cross-section of the outer hole frame is the positioning reference surface, which is used to measure and adjust the extension distance of the L-shaped water seal arc sealing surface 14a.

[0045] Multiple arc-shaped support plates 6 are installed on the arc-shaped support plates 1c of multiple support modules with large spacing, and together with the C-shaped support plate 1b, they form the arc-shaped support surface at the bottom of the tooling. Stop blocks 6a are provided at the four corners of the arc-shaped support plate to prevent the arc-shaped support plate from rotating on the arc-shaped support frame, and holes are also provided on the arc-shaped support plate to reduce weight.

[0046] like Figures 9 to 12 As shown, the outer straight section pressure plate 7, the outer arc section pressure plate 8 and the outer C-type clamp 11 are used to clamp and fix one end of the C-type water seal and the L-type water seal on the outer matching hole frame; the inner straight section pressure plate 9, the inner arc section pressure plate 10 and the inner C-type clamp 12 are used to clamp and fix the other end of the C-type water seal on the inner matching hole frame. The cross-section of the outer straight section pressure plate 7 and the outer arc section pressure plate 8 is L-shaped, which can support the bottom of the L-type water seal to facilitate the adjustment of the height of the L-type water seal. The outer C-type clamp 11 is provided with an extension column 11a, which is used to avoid the arc sealing surface 14a of the L-type water seal when clamping. Each pressure plate is provided with a through hole, and the pressure plate is provided with a number. After each pressure plate is clamped and fixed according to the number, the position of each through hole corresponds to the matching drill hole on the corresponding matching hole plate. The diameter of the through hole is larger than the diameter of the matching drill hole, so that the through hole and the matching drill hole do not need to be accurately aligned when drilling.

[0047] When the tooling is used, first unfold the C-type and L-type water seals according to the on-site installation status and install them into the gap between the inner and outer matching hole frames, then adjust the distance between the arc sealing surface of the L-type water seal and the upper end face of the outer matching hole plate to ensure that the compression margin of the arc sealing surface meets the sealing requirements when the sealing frame is pushed out after the water seal is installed. Finally, use multiple pressing plates and C-type clamps to clamp and fix the water seal to the inner and outer matching hole frames. After the water seal is fixed, the electric push rods are synchronously driven to drive the outer matching hole frame to expand and contract, which can simulate the expansion and contraction action of the water seal with the docking sealing frame. At this time, check whether there are hidden cracks, debonding and other defects in various parts of the C-type water seal. After the water seal expansion and contraction action is detected to be normal, use hollow drills and other equipment to complete the drilling of the water seal with the matching drill holes on the tooling as a guide.

[0048] The specific use method of the tooling is as follows:

[0049] 1) Press each support module Figure 3, Figure 4 and Figure 5 The position relationship is placed on a horizontal basis. Figure 3 It is a schematic diagram of the front view and top view of the tooling (without water seal, pressure plate and C-type clamp), where: Figure 3 For the main view, Figure 4 It is a top view;

[0050] Each lifting frame is in the retracted state, and then the hole plates of the inner and outer hole frames are installed on the support modules according to the numbers, and the tooling is leveled at all locations through the support block foot cups.

[0051] 2) Expand the C-type water seal according to the on-site installation status and place it in the gap between the inner and outer hole frames. Adjust the position of the C-type water seal so that the arc section at the bottom of the water seal is supported by the C-type support plate and the arc support plate. The top of the two side walls of the water seal are flush with the inner and outer hole frames. Fig.11 shown.

[0052] 3) Use each inner pressure plate and multiple inner C-type clips to clamp and fix the inner side of the C-type water seal on the inner hole frame. Install each pressure plate according to the number. When installing, pay attention to adjusting the position of the pressure plate so that each through hole basically corresponds to the corresponding drill hole on the hole plate.

[0053] 5) According to the designed distance between the L-shaped water seal sealing surface 14a and the original on-site installation positioning reference surface (generally the thrust block of the docking sealing frame), combined with the dimensions of the tooling and the L-shaped water seal, calculate the distance S from the sealing surface to the tooling positioning reference surface (the upper end surface of the L-shaped section of the outer matching hole frame).

[0054] 4) Expand the L-shaped water seal according to the on-site installation status and put it into the gap of the tooling, and put the L-shaped water seal close to the inner surface of the outer wall of the C-shaped water seal, then measure and adjust the distance from the sealing surface of each part of the L-shaped water seal to the positioning reference surface to S in sections, and finally use each outer pressure plate and multiple outer C-shaped clamps to clamp the outer side of the L-shaped water seal and the C-shaped water seal on the outer hole frame of the tooling. Each pressure plate is installed according to the number, and pay attention to adjusting the position of the pressure plate during installation so that each through hole basically corresponds to the matching drill hole on the corresponding hole plate.

[0055] 5) After the water seal is clamped and fixed on the tooling, the electric push rods 1i on all the supporting modules are synchronously driven to extend or retract the outer hole frame of the tooling as a whole, simulating the telescopic action of the water seal with the docking sealing frame. At this time, it is possible to check whether there are hidden cracks, debonding and other defects in various parts of the C-type water seal. Fig.12 , 13 shown.

[0056] 6) After checking that the water seal is expanding and contracting normally, use the drill holes on the tooling as a guide and use a hollow drill or other equipment to complete the drilling of the water seal.

[0057] In this embodiment, the support module may not be provided with a lifting frame, that is, the outer hole frame of the tooling is set to be fixed. At this time, the tooling does not have the function of simulating the extension and retraction of the docking sealing frame.

[0058] The foot cup at the bottom of the support module can be replaced by other height adjustment mechanisms, and the height adjustment mechanism may not be provided when the flatness of the horizontal foundation meets the requirements.

[0059] If a shorter orifice plate is used, that is, the spacing between the supporting modules is smaller, the degree of collapse of the C-type water seal between the modules is also smaller. At this time, the arc-shaped support plate can be omitted, or a movable bracket can be used to support the lower part of the C-type water seal.

[0060] Instead of using an L-shaped cross section, each orifice plate may use a thickened flat plate or other cross-sectional shapes with better rigidity.

[0061] The through holes on each pressing plate can be changed into long slots or notches toward the side, as long as space for matching holes can be left while the water seal is compressed.

[0062] The outer C-clamp with extension column, as well as the conventional inner C-clamp, can be replaced by other clamping tools.

[0063] The modular ship lift docking sealing device C-type and L-type water seal installation hole pre-drilling tooling includes multiple identical support modules and multiple different matching hole plates. Multiple support modules are arranged in a U-shape on a horizontal basis in accordance with the unfolded state of the water seal. The support module is provided with a C-type support plate adapted to the cross section of the C-type water seal. Multiple outer straight-section matching hole plates and two outer arc-section matching hole plates are installed on the top of the outward side wall of the C-type support plate of each support module to form a U-shaped outer matching hole frame; multiple inner straight-section matching hole plates and two inner arc-section matching hole plates are installed on the top of the inward side wall of the C-type support plate of each support module to form a U-shaped inner matching hole frame. The gap between the inner and outer matching hole frames is the installation space of the water seal. The size and relative position of each matching drill hole on the matching hole frame are consistent with the bolt installation holes of the water seal on site.

[0064] The above description is only a preferred embodiment of the present invention and is used to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
