Description

Technical Field

[0001] This utility model relates to the field of brake pad clamp technology, specifically to a brake pad installation clamp for a marine anchor winch. Background Technology

[0002] Anchor winches are used for mooring lines and anchor chain deployment / retrieval on ships. Brake pads, as components of these winches, are consumable materials and are mostly replaced during ship repairs. Brake pads with poor installation quality or wear exceeding 25% of their thickness should be replaced, directly affecting the ship's maneuverability and safety. Medium-sized ships typically have around a dozen anchor winch brake pads. Medium-sized shipyards repair approximately 250 ships annually. The demand for replacing and installing anchor winches brake pads is high and profitable, but the timeframes are short, and most are urgent. Delayed installation can affect anchor chain deployment / retrieval of anchor / mooring lines, consequently impacting undocking and departure. Therefore, high-quality and rapid completion is essential.

[0003] Currently, the brake pads are tightly bonded to the inner wall of the steel brake band. This is usually achieved by embedding multiple countersunk copper screws into the brake pads at least 30% of their thickness and tightening them evenly from the inside out. This ensures that when the braking system is activated and tightened, the brake pads are pressed tightly against the brake hub along with the steel band, using friction to slow down and stop the anchor and cable being dragged by the anchor winch.

[0004] Marine arc-shaped strip gates are mostly 1000-2000mm in diameter, with a relatively long arc. The thickness, strength, toughness, and elasticity of the gate pad itself require a certain degree of fit and tightness. This necessitates a good tangency between the fixing screw points and the arc. Currently, the main construction process uses a multi-point fastening and segmented construction method, employing multiple clamps and fixtures to fix the mounting holes point by point. This method is inefficient, produces low quality, and cannot meet production requirements, assembly precision requirements, or labor costs. Utility Model Content

[0005] To address the problems in the background art, this utility model proposes a marine anchor winch brake pad installation fixture, which improves work efficiency and achieves the effect of cost reduction and efficiency improvement.

[0006] To solve the above problems, this utility model adopts the following technical solution: a marine anchor winch brake pad installation clamp, comprising a clamp body, a rotating push rod, and an arc-blade pressing device. The clamp body is a C-shaped hook piece, and the opening of the clamp body is used to engage the brake band and the brake pad. Both the brake band and the brake pad are arc-shaped strips. The brake band and the brake pad are fixed together by multiple countersunk copper screws. A through hole is opened on the front side of the clamp body. The arc-blade pressing device includes an arc-shaped template and a semi-threaded sleeve. The arc-shaped template and the multiple countersunk copper screws are spaced apart. The rear arc surface of the arc-shaped template fits against the front side of the brake pad. The semi-threaded sleeve is welded to the front side of the arc-shaped template. The inner end of the rotating push rod passes through the through hole and can be threadedly connected to the semi-threaded sleeve.

[0007] Furthermore, the number of the arc-shaped templates is two, and the two arc-shaped templates are arranged in parallel and spaced apart. Each of the two arc-shaped templates has a plurality of positioning holes. The arc blade pressing device also includes two connecting rods, the two ends of which are inserted into the corresponding positioning holes of the two arc-shaped templates to connect and fix the two arc-shaped templates.

[0008] Furthermore, both connecting rods are magnetic rods, and there is a magnetic force between the two arc-shaped templates and the two magnetic rods.

[0009] Furthermore, there are three types of arc-shaped templates, with arc radii of 500mm, 755mm, and 900mm respectively.

[0010] Furthermore, the rotating push rod includes a lead screw head and a handle. The inner end of the lead screw head has a detachable stepped structure, and the outer end of the lead screw head is vertically connected to the handle.

[0011] The beneficial effects of this utility model are as follows: This utility model, through the combined action of the clamp body, rotating push rod, and arc-shaped pressing device, can clamp and fix the arc-shaped elongated brake pad and brake band, while avoiding the screw holes on the brake pad and brake band. Compared to traditional installation clamps, this utility model eliminates the need for dozens of clamping structures for multi-point fixation, resulting in lower operational difficulty and better clamping effect. It ensures more balanced force distribution at multiple points and more uniform contact between the arc-shaped surfaces. Due to the fewer clamps required, the matching accuracy of the through holes between the brake pad and brake band is higher. Because there is no positional interference between the arc-shaped template structure and the countersunk copper screws and screw holes, this utility model ensures the perpendicularity of the holes and the free screwing in and out of the countersunk copper screws. This improves the efficiency of brake pad assembly and disassembly, achieving cost reduction and efficiency improvement. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This invention, through the combined action of the clamp body 1, the rotating push rod 2, and the arc-shaped pressing device 3, can clamp and fix the arc-shaped elongated brake pad 5 and brake band 4, while avoiding the screw holes on the brake pad 5 and brake band 4. Compared with traditional installation clamps, this invention eliminates the need for dozens of clamping structures for multi-point fixation, resulting in lower operational difficulty and better clamping effect. It ensures more balanced force distribution at multiple points and more uniform contact between the arc-shaped surfaces. Due to the fewer clamps required, the through-hole matching accuracy between the brake pad 5 and brake band 4 is higher. Because there is no positional interference between the structure of the arc-shaped template 7 and the countersunk copper screw 6 and screw holes, this invention ensures the perpendicularity of the holes and the free screwing in and out of the countersunk copper screw 6. This improves the efficiency of brake pad 5 assembly and disassembly, achieving cost reduction and efficiency improvement.

[0021] Specifically, such as Figures 1 to 5As shown, a mounting clamp for a marine anchor winch brake pad 5 includes a clamp body 1, a rotating push rod 2, and an arc-shaped pressing device 3. The clamp body 1 is a C-shaped hook. The opening of the clamp body 1 is used to engage the brake band 4 and the brake pad 5. Both the brake band 4 and the brake pad 5 are arc-shaped strips. The brake band 4 and the brake pad 5 are fixed together by multiple countersunk copper screws 6. A through hole is opened on the front side of the clamp body 1. The arc-shaped pressing device 3 includes an arc-shaped template 7 and a semi-threaded sleeve 8. The arc-shaped template 7 and the multiple countersunk copper screws 6 are spaced apart. The rear arc surface of the arc-shaped template 7 fits against the front side of the brake pad 5. The semi-threaded sleeve 8 is welded to the front side of the arc-shaped template 7. The inner end of the rotating push rod 2 passes through the through hole and can be threadedly connected to the semi-threaded sleeve 8.

[0022] Furthermore, there are two arc-shaped templates 7, which are arranged in parallel and spaced apart. Each arc-shaped template 7 has multiple positioning holes 9. The arc-shaped blade pressing device 3 also includes two connecting rods 10, both ends of which pass through the corresponding positioning holes 9 of the two arc-shaped templates 7 to connect and fix them. By having the two arc-shaped templates 7 directly contact the arc surface of the brake pad 5, the clamping effect is ensured. Because the two arc-shaped templates 7 are separated by countersunk copper screws 6, interference with the position of the countersunk copper screws 6 is avoided, ensuring that the countersunk copper screws 6 can be tightened normally.

[0023] Furthermore, both connecting rods 10 are magnetic rods, and there is a magnetic force between the two arc-shaped templates 7 and the two magnetic rods. Because there is a magnetic force between the two magnetic rods and the two arc-shaped templates 7, after one arc-shaped template 7 is fixed, the attraction force of the two magnetic rods can fix the other arc-shaped template 7, improving the stability of the device. Of course, the two connecting rods 10 can also be stainless steel round bars. The two connecting rods 10 connect the two arc-shaped templates 7 together, and when subjected to clamping force, the two connecting rods 10 ensure that the two arc-shaped templates 7 have the same stress state.

[0024] Furthermore, there are three types of arc-shaped templates 7, with arc radii of 500mm, 755mm, and 900mm respectively. Arc-shaped templates 7 with different arc radii can be used for the installation and removal of brake pads 5 with different arc radii.

[0025] Furthermore, the rotating push rod 2 includes a lead screw head 11 and a handle 12. The inner end of the lead screw head 11 has a detachable stepped structure, and the outer end of the lead screw head 11 is vertically connected to the handle 12. The detachable stepped structure of the lead screw head allows for quick replacement to match different sizes of half-thread sleeves 8, improving practicality.

[0026] In use, this invention, through the combined action of the clamp body 1, the rotating push rod 2, and the arc-shaped pressing device 3, can clamp and fix the arc-shaped elongated brake pad 5 and brake band 4, while avoiding the screw holes on the brake pad 5 and brake band 4. Compared with traditional installation clamps, this invention eliminates the need for dozens of clamping structures for multi-point fixation, resulting in lower operational difficulty and better clamping effect. It ensures more balanced force distribution at multiple points and more uniform contact between the arc-shaped surfaces. Due to the fewer clamps required, the through-hole matching accuracy between the brake pad 5 and brake band 4 is higher. Because there is no positional interference between the structure of the arc-shaped template 7 and the countersunk copper screw 6 and screw holes, this invention ensures the perpendicularity of the holes and the free screwing in and out of the countersunk copper screw 6. This improves the efficiency of brake pad 5 assembly and disassembly, achieving cost reduction and efficiency improvement.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
