Description

Technical Field

[0001] This invention belongs to the field of shipbuilding technology, and specifically relates to a cable penetration sealing adjustment and fixing device. Background Technology

[0002] During the shipbuilding phase, through-hole components are used for cable passage. Sealing is achieved between cables and through-hole components, and between cables themselves, using stuffing boxes. Before stuffing, the spacing between cables must be greater than 8mm, and the spacing between cables and the through-hole component wall must be greater than 10mm. Sufficient spacing ensures that the stuffing boxes can fully adhere and seal.

[0003] Currently, the main method used is to install cable scrap sections at both ends. This method can ensure the required spacing between cables and between cables and the wall of the through-hole in the vicinity of the ends. However, the spacing between cables and between cables and the wall of the through-hole inside cannot be guaranteed because it cannot be visually inspected. During the subsequent sealing process, since the ends are sealed, the sealing effect of the internal area cannot be checked. However, after the ship has been in operation for a period of time, the end-face stuffing box may fail due to environmental factors such as oxidation and temperature changes, and the internal area may fail to seal due to the insufficient spacing. Moreover, this method of installing cable scrap sections at both ends is time-consuming. Because the cables are not taut and straight, the cable spacing in the vicinity of the ends changes when the stuffing box is filled after adjustment, or it may be affected by cross-operations. The risk of accidental contact and disturbance by personnel is still unavoidable, and cases of rework due to sealing failure still occur frequently. Summary of the Invention

[0005] An adjustable spacing clamp includes a frame, wherein the frame is provided with a plurality of position-adjustable locking positions for cables to pass through;

[0006] A top support device includes a connector and a top support rod. The connector is used to connect with a clamping through member. The top support rod is disposed between the connector and the adjustable spacing clamp, and the top support rod can adjust the distance between the connector and the adjustable spacing clamp.

[0007] Furthermore, the frame includes a rectangular frame formed by two parallel first rods and two parallel second rods, with first through slots arranged opposite to each other on the two first rods and second through slots on the two second rods.

[0008] The frame is provided with a plurality of first adjusting columns and second adjusting columns. The first adjusting columns are parallel to the first rod and both ends protrude from the second through slot. The second adjusting columns are parallel to the second rod and both ends protrude from the first through slot.

[0009] The first adjusting column can move along the second through groove, the second adjusting column can move along the first through groove, and the gap between the first adjusting column and the second adjusting column constitutes the locking position.

[0010] Furthermore, adjusting nuts are fitted onto the ends of the first adjusting column and the second adjusting column.

[0011] Furthermore, a nut that mates with the top support rod is fixedly provided on the outer edge of the frame, and the top support rod is connected to the frame through the nut.

[0012] Furthermore, the connector includes a clamping band that can be fitted onto the clamping through member, and the outer wall of the clamping band is fixedly provided with a connecting lug perpendicular to the top support rod, and one end of the top support rod abuts against the connecting lug.

[0013] Furthermore, the connecting ear has a skirt on the side facing the top support rod.

[0015] Furthermore, it also includes a flow guide channel, on which a suspension hook is fixedly provided, and the flow guide channel is set below the top support rod through the suspension hook.

[0016] Furthermore, the flow channel is connected to the collection bucket via a flow guide pipe.

[0018] 1. Improved efficiency, high adjustment accuracy, and simple structure of adjustable spacing fixture make it easy to operate and realize the adjustment of inter-layer spacing and inter-row spacing;

[0027] Reference Figures 1-3 The cable penetration sealing adjustment and fixing device proposed in this invention mainly includes an adjustable spacing clamp, a top support device and a flow guide groove.

[0028] Among them, such as Figure 1 As shown, the adjustable spacing fixture proposed in this application is made of stainless steel columns and a stainless steel plate frame. The stainless steel column is a flat cylindrical shape cut from 8mm in diameter to 8mm wide and 4mm thick, with threads tapped within a 40mm range at both ends. It has a vertical diameter of 200mm and a horizontal length of 400mm, and is fixed to the stainless steel plate frame at both ends with M8 butterfly nuts. The adjustment groove on the frame adopts a multi-segmented design. The stainless steel plate frame is 4mm thick, 360mm long, 160mm high, and 16mm wide, with through grooves spaced 10mm apart, 60mm long and 4mm wide, for adjusting the spacing of the stainless steel column installation.

[0029] like Figure 2 As shown, the top support device is made of stainless steel, with M5 nuts welded to the four corners of the frame, and 200mm long M5 butterfly bolts for top support. A 20mm wide and 5mm thick clamping band is provided to clamp the through component. The clamping band is fitted with four semi-circular connecting lugs with a diameter of 40mm and a thickness of 4mm. On the side of the connecting lugs facing the M5 butterfly bolts, a 4mm diameter cylinder is welded along the circumference to prevent the M5 butterfly bolts from slipping off the connecting lugs during operation.

[0030] like Figure 3 As shown, the flow channel is made of bent stainless steel plate, which is 1mm thick, 400mm long, 40mm wide, and 20mm high. It has U-shaped openings at both ends and hooks at the openings, which are hung on the bolts of the top support device and installed directly below the end face of the through-piece. A flow pipe (not shown in the attached diagram) connecting to the collection tank is installed according to the required overflow volume.

[0031] Comparison Figure 4 The working process of this invention is as follows:

[0032] Adjustable spacing clamps are installed on both ends of the cable connection piece;
