Description

Technical Field

[0001] The invention relates to the technical field of hatch cover tooling, in particular to a portable full-working-condition hatch cover sealing rubber installation tooling. Background Art

[0002] Common marine hatch covers are primarily categorized as lift-off, side-sliding, and folding. All of these types experience rubber degradation during use. Therefore, after a ship enters the shipyard, these aging issues require replacement. Replacement is typically performed onboard or on a dock cradle. Onboard replacement is categorized into three types: side-opening, hydraulic cylinder-folding, and hoisted stacking. Hatch covers typically remain flat on dock cradles when lowered to the ground.

[0003] In the past, the replacement of these types of hatch cover rubber was mainly completed by the inertia of the impact of iron rods. During installation, workers could only swing the iron rods upward from the bottom and hit the rubber strips, poking the rubber strips into the rubber grooves little by little. This method was not only physically demanding but also inefficient.

[0004] In order to reduce the labor intensity of workers and improve the installation efficiency of hatch cover rubber, this application designs a portable all-working condition hatch cover sealing rubber installation tool, which is not only light and flexible, but also saves time and labor. At the same time, it can be used for replacing rubber strips of various types of hatch covers under various working conditions. Summary of the Invention

[0005] The purpose of the present invention is to provide a portable full-working condition hatch cover sealing rubber installation tool to solve the problem proposed in the above background technology that the existing hatch cover rubber replacement is completed by manually hitting an iron rod through the inertia of the impact, which not only consumes physical strength but also has low efficiency.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a portable all-working-condition hatch cover sealing rubber installation tool, comprising: a support rod, the support rod is in the shape of a "7", an anti-slip plate is fixedly provided on the top of the support rod, a limit rod is provided on one side of the middle of the support rod, and handles are provided on both sides of the limit rod on the outer wall of the middle of the support rod, and a plurality of through adjustment holes are opened on the lower half of the support rod, a rotating frame is rotatably provided on the outer side of one of the adjustment holes, a long arm is provided on the outer wall of one end of the rotating frame, and a short arm is provided on the outer wall of the other end, and a pressure block is provided at one end of the short arm.

[0007] Preferably, the anti-skid plate is L-shaped, and one side of the bottom of the anti-skid plate is used to abut against the outer wall of the hatch cover. Anti-skid serrations are provided at the abutment between the bottom of the anti-skid plate and the outer wall of the hatch cover. An outward draft angle is provided at the connection between the anti-skid plate and the support rod, so that the thickness of the connection between the anti-skid plate and the support rod is increased, and a pad is provided on the top surface of the support rod.

[0008] Preferably, a rotating shaft is inserted into the adjusting hole, through holes for inserting the rotating shaft are opened on both sides of the rotating frame, and the rotating frame is sleeved on the outside of the support rod, with the rotating shaft serving as a rotating support shaft.

[0009] Preferably, a sleeve is fixed to the outside of the adjustment hole by a pin, a rotating shaft is fixed on both sides of the outer wall of the sleeve, and through holes for inserting the rotating shaft are opened on both sides of the rotating frame. The rotating frame is sleeved on the outside of the sleeve and uses the rotating shaft as a rotating support shaft.

[0010] Preferably, the upper half of the sleeve is provided with two through holes, and the through holes and the adjusting holes are internally connected with limit pins.

[0011] Preferably, the limiting pin is U-shaped, and buckles are provided at both open ends of the limiting pin.

[0012] Preferably, the outer wall of the limiting rod is provided with an external thread, a threaded sleeve is provided on the outside of the limiting rod, a fixed shaft is provided on the upper and lower outer walls of the threaded sleeve, a guide wheel is provided at one end of the fixed shaft, and the circumferential outer wall of the guide wheel abuts against one side of the outer wall of the hatch cover.

[0013] Preferably, locking nuts are provided on the outer wall of the limiting rod at both ends of the threaded sleeve.

[0014] Preferably, the short arm is L-shaped, comprising a long side and a short side, a pressing block is provided at the top end of the short side, and one end of the long side is fixedly connected to the outer wall of one end of the rotating frame.

[0015] Preferably, two sides of the rotating frame are provided with through strip grooves, and the rotating shaft is inserted into the strip grooves.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention realizes the installation of rubber strips when the portable full-working-condition hatch cover sealing rubber installation tool is used by providing the support rod, rotating frame, long arm and short arm. The rubber strips can be installed when the hatch cover is unloaded from the ship in a lifting, side-shifting or folding manner and placed on the dock cradle for repair. The jacking mode and the clamping mode can be adopted. When the clamping mode is used, one end of the anti-skid plate of the support rod is abutted against one side of the outer wall of the hatch cover, so that the rotating frame is located outside the rubber strip installation groove.

In the jacking mode, one side of the pad is placed on the ground, and the rotating frame is flipped 180 degrees so that the top surface of the pressure block faces upward. Also based on the principle of leverage, the staff continuously lifts and presses the long arm to press the rubber strip into the rubber strip installation groove through the pressure block, reducing labor intensity and improving work efficiency.

[0019] Since the thickness of hatch covers of different ship types is different, the adjustable shaft method can adjust the height of the rotating frame on the support rod by adjusting the hole and cooperating with the pin-type rotating shaft, thereby adjusting the size of the clamp opening to adapt to hatch covers of different thicknesses.

[0020] The entire device can be used for the installation of sealing rubbers for hatch covers of the lifting type, side-sliding type, and folding type. It has a wide range of applications and basically meets the requirements for installing rubber strips on hatch covers under various working conditions. It reduces the conditions for replacing rubber strips on hatch covers and the total cost of replacing rubber strips, which can greatly reduce the labor intensity of workers and improve work efficiency.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Example 1: Please refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 8 The present invention provides a technical solution: a portable, all-condition hatch cover sealing rubber installation tool, comprising: a strut 1 in the shape of a "7" (likely a character "7"). A skid plate 12 is fixedly mounted on the top of the strut 1. A limit rod 2 is provided on one side of the middle portion of the strut 1. Handles 3 are provided on the outer wall of the middle portion of the strut 1, located on both sides of the limit rod 2. A plurality of through adjustment holes 4 are formed in the lower half of the strut 1. A rotating frame 6 is rotatably mounted outside one of the adjustment holes 4. A long arm 7 is provided on the outer wall of the rotating frame 6 at one end, and a short arm 8 is provided on the outer wall of the other end. A pressure block 15 is provided at one end of the short arm 8. The skid plate 12 of the strut 1 is brought into contact with one side of the hatch cover outer wall, positioning the rotating frame 6 outside the rubber strip installation slot. Due to the rotational connection between the rotating frame 6 and the strut 1, the rotating portion of the rotating frame 6 serves as a fulcrum, and the long arm 7 and short arm 8 form a lever. By continuously lifting and pressing the long arm 7, the operator presses the rubber strip into the rubber strip installation slot via the pressure block 15, thereby reducing labor intensity and improving work efficiency.

[0032] The anti-skid plate 12 is L-shaped, and one side of the bottom of the anti-skid plate 12 is used to abut against the outer wall of the hatch cover. Anti-skid serrations are provided at the abutment between the bottom of the anti-skid plate 12 and the outer wall of the hatch cover. The connection between the anti-skid plate 12 and the strut 1 is provided with an outward draft angle, so that the thickness of the connection between the anti-skid plate 12 and the strut 1 is increased. The top surface of the strut 1 is provided with a pad 13. The pad 13 is beneficial to increase the contact area with the ground when the entire tooling is used in a jacking mode, thereby increasing the stability of the support.

[0033] A rotating shaft 9 is inserted into the adjusting hole 4, and through holes for inserting the rotating shaft 9 are opened on both sides of the rotating frame 6. The rotating frame 6 is sleeved on the outside of the support rod 1, and the rotating shaft 9 is used as the rotating support shaft. The rotating shaft 9 is directly inserted into the adjusting hole and the rotating frame 6. This connection method is simple, effective and easy to operate.

[0034] A sleeve 5 is fixed to the outside of the adjustment hole 4 by a pin, and a rotating shaft 9 is fixed on both sides of the outer wall of the sleeve 5. Through holes for inserting the rotating shaft 9 are opened on both sides of the rotating frame 6. The rotating frame 6 is sleeved on the outside of the sleeve 5, and the rotating shaft 9 is used as a rotating support shaft. The sleeve 5 is used as a support for the rotating shaft 9. Compared with directly inserting the rotating shaft 9 into the adjustment hole 4, the wear of the adjustment hole 4 can be reduced, because the sleeve 5 is limited by two adjustment holes 4 and can share the force.

[0035] The upper half of the sleeve 5 is provided with two through-holes extending therethrough, and a limit pin 10 is inserted into the through-holes and the adjustment hole 4. The limit pin 10 is U-shaped, and a buckle 11 is provided at each open end of the limit pin 10. The limit pin 10 secures the sleeve 5 to the strut 1, achieving a detachable connection of the sleeve 5 and facilitating adjustment of the position of the sleeve 5 on the strut 1. The U-shaped limit pin 10 provides more stable positioning and is also easy to remove. The buckle 11 is an iron piece that is clamped to the open end of the limit pin 10 and is used to prevent the limit pin 10 from separating from the sleeve 5 and the strut 1 when the limit pin 10 is working.

[0036] An external thread is provided on the outer wall of the limit rod 2, and a threaded sleeve is provided on the outside of the limit rod 2. Fixed shafts are provided on the upper and lower outer walls of the threaded sleeve, and a guide wheel 14 is provided at one end of the fixed shaft. The circumferential outer wall of the guide wheel 14 abuts against one side of the outer wall of the hatch cover. Locking nuts are provided at both ends of the threaded sleeve on the outer wall of the limit rod 2. By installing the guide wheel 14 on the limit rod 2, the entire tooling can be easily translated along the installation direction of the rubber strip when the rubber strip is installed, thereby improving work efficiency.

[0037] The short arm 8 is L-shaped, and the short arm includes a long side and a short side. A pressure block 15 is provided at the top of the short side, and one end of the long side is fixedly connected to the outer wall of one end of the rotating frame 6. The L-shaped design of the short arm 8 makes it convenient for the pressure block 15 to squeeze the rubber strip.

[0038] There are through strip grooves 16 on both sides of the rotating frame 6, and the rotating shaft 9 is inserted into the strip grooves 16. Through the design of the strip grooves 16 on the rotating frame 6, the position of the rotating support shaft of the rotating frame 6 can be adjusted in a small range, thereby adjusting the position of the short arm 8 so that the pressure block 15 can cover the entire width of the rubber strip.

[0039] This embodiment shows the upper and lower clamping in the clamping mode. When using the clamping mode, one end of the anti-skid plate 12 of the support rod 1 is abutted against one side of the outer wall of the hatch cover, so that the rotating frame 6 is located outside the rubber strip installation groove. Due to the rotational connection between the rotating frame 6 and the support rod 1, the rotating part of the rotating frame 6 is used as a fulcrum, and the long arm 7 and the short arm 8 form a lever principle. The staff continuously lifts and presses the long arm 7, and presses the rubber strip into the rubber strip installation groove through the pressure block 15, thereby reducing labor intensity and improving work efficiency.

[0040] Example 2: Please refer to Figure 3-Figure 4The present invention provides a technical solution: a portable, all-condition hatch cover sealing rubber installation tool, comprising: a strut 1 in the shape of a "7" (likely a character "7"). A skid plate 12 is fixedly mounted on the top of the strut 1. A limit rod 2 is provided on one side of the middle portion of the strut 1. Handles 3 are provided on the outer wall of the middle portion of the strut 1, located on both sides of the limit rod 2. A plurality of through adjustment holes 4 are formed in the lower half of the strut 1. A rotating frame 6 is rotatably mounted outside one of the adjustment holes 4. A long arm 7 is provided on the outer wall of the rotating frame 6 at one end, and a short arm 8 is provided on the outer wall of the other end. A pressure block 15 is provided at one end of the short arm 8. The skid plate 12 of the strut 1 is brought into contact with one side of the hatch cover outer wall, positioning the rotating frame 6 outside the rubber strip installation slot. Due to the rotational connection between the rotating frame 6 and the strut 1, the rotating portion of the rotating frame 6 serves as a fulcrum, and the long arm 7 and short arm 8 form a lever. By continuously lifting and pressing the long arm 7, the operator presses the rubber strip into the rubber strip installation slot via the pressure block 15, thereby reducing labor intensity and improving work efficiency.

[0041] The anti-skid plate 12 is L-shaped, and one side of the bottom of the anti-skid plate 12 is used to abut against the outer wall of the hatch cover. Anti-skid serrations are provided at the abutment between the bottom of the anti-skid plate 12 and the outer wall of the hatch cover. The connection between the anti-skid plate 12 and the strut 1 is provided with an outward draft angle, so that the thickness of the connection between the anti-skid plate 12 and the strut 1 is increased. The top surface of the strut 1 is provided with a pad 13. The pad 13 is beneficial to increase the contact area with the ground when the entire tooling is used in a jacking mode, thereby increasing the stability of the support.

[0042] A rotating shaft 9 is inserted into the adjusting hole 4, and through holes for inserting the rotating shaft 9 are opened on both sides of the rotating frame 6. The rotating frame 6 is sleeved on the outside of the support rod 1, and the rotating shaft 9 is used as the rotating support shaft. The rotating shaft 9 is directly inserted into the adjusting hole and the rotating frame 6. This connection method is simple, effective and easy to operate.

[0043] A sleeve 5 is fixed to the outside of the adjustment hole 4 by a pin, and a rotating shaft 9 is fixed on both sides of the outer wall of the sleeve 5. Through holes for inserting the rotating shaft 9 are opened on both sides of the rotating frame 6. The rotating frame 6 is sleeved on the outside of the sleeve 5, and the rotating shaft 9 is used as a rotating support shaft. The sleeve 5 is used as a support for the rotating shaft 9. Compared with directly inserting the rotating shaft 9 into the adjustment hole 4, the wear of the adjustment hole 4 can be reduced, because the sleeve 5 is limited by two adjustment holes 4 and can share the force.

[0044] The upper half of the sleeve 5 is provided with two through-holes extending therethrough, and a limit pin 10 is inserted into the through-holes and the adjustment hole 4. The limit pin 10 is U-shaped, and a buckle 11 is provided at each open end of the limit pin 10. The limit pin 10 secures the sleeve 5 to the strut 1, achieving a detachable connection of the sleeve 5 and facilitating adjustment of the position of the sleeve 5 on the strut 1. The U-shaped limit pin 10 provides more stable positioning and is also easy to remove. The buckle 11 is an iron piece that is clamped to the open end of the limit pin 10 and is used to prevent the limit pin 10 from separating from the sleeve 5 and the strut 1 when the limit pin 10 is working.

[0045] An external thread is provided on the outer wall of the limit rod 2, and a threaded sleeve is provided on the outside of the limit rod 2. Fixed shafts are provided on the upper and lower outer walls of the threaded sleeve, and a guide wheel 14 is provided at one end of the fixed shaft. The circumferential outer wall of the guide wheel 14 abuts against one side of the outer wall of the hatch cover. Locking nuts are provided at both ends of the threaded sleeve on the outer wall of the limit rod 2. By installing the guide wheel 14 on the limit rod 2, the entire tooling can be easily translated along the installation direction of the rubber strip when the rubber strip is installed, thereby improving work efficiency.

[0046] The short arm 8 is L-shaped, and the short arm includes a long side and a short side. A pressure block 15 is provided at the top of the short side, and one end of the long side is fixedly connected to the outer wall of one end of the rotating frame 6. The L-shaped design of the short arm 8 makes it convenient for the pressure block 15 to squeeze the rubber strip.

[0047] There are through strip grooves 16 on both sides of the rotating frame 6, and the rotating shaft 9 is inserted into the strip grooves 16. Through the design of the strip grooves 16 on the rotating frame 6, the position of the rotating support shaft of the rotating frame 6 can be adjusted in a small range, thereby adjusting the position of the short arm 8 so that the pressure block 15 can cover the entire width of the rubber strip.

[0048] This embodiment shows lateral clamping in the clamping mode. When the clamping mode is used, one end of the anti-skid plate 12 of the support rod 1 is abutted against one side of the outer wall of the hatch cover, so that the rotating frame 6 is located outside the rubber strip installation groove. Due to the rotational connection between the rotating frame 6 and the support rod 1, the rotating part of the rotating frame 6 is used as a fulcrum, and the long arm 7 and the short arm 8 form a lever principle. The staff continuously lifts and presses the long arm 7, and presses the rubber strip into the rubber strip installation groove through the pressure block 15, thereby reducing labor intensity and improving work efficiency.

[0049] Example 3: Please refer to Figure 5-Figure 6 The present invention provides a technical solution: a portable, all-condition hatch cover sealing rubber installation tool, comprising: a strut 1 in the shape of a "7" (likely a character "7"). A skid plate 12 is fixedly mounted on the top of the strut 1. A limit rod 2 is provided on one side of the middle portion of the strut 1. Handles 3 are provided on the outer wall of the middle portion of the strut 1, located on both sides of the limit rod 2. A plurality of through adjustment holes 4 are formed in the lower half of the strut 1. A rotating frame 6 is rotatably mounted outside one of the adjustment holes 4. A long arm 7 is provided on the outer wall of the rotating frame 6 at one end, and a short arm 8 is provided on the outer wall of the other end. A pressure block 15 is provided at one end of the short arm 8. The skid plate 12 of the strut 1 is brought into contact with one side of the hatch cover outer wall, positioning the rotating frame 6 outside the rubber strip installation slot. Due to the rotational connection between the rotating frame 6 and the strut 1, the rotating portion of the rotating frame 6 serves as a fulcrum, and the long arm 7 and short arm 8 form a lever. By continuously lifting and pressing the long arm 7, the operator presses the rubber strip into the rubber strip installation slot via the pressure block 15, thereby reducing labor intensity and improving work efficiency.

[0050] The anti-skid plate 12 is L-shaped, and one side of the bottom of the anti-skid plate 12 is used to abut against the outer wall of the hatch cover. Anti-skid serrations are provided at the abutment between the bottom of the anti-skid plate 12 and the outer wall of the hatch cover. The connection between the anti-skid plate 12 and the strut 1 is provided with an outward draft angle, so that the thickness of the connection between the anti-skid plate 12 and the strut 1 is increased. The top surface of the strut 1 is provided with a pad 13. The pad 13 is beneficial to increase the contact area with the ground when the entire tooling is used in a jacking mode, thereby increasing the stability of the support.

[0051] A rotating shaft 9 is inserted into the adjusting hole 4, and through holes for inserting the rotating shaft 9 are opened on both sides of the rotating frame 6. The rotating frame 6 is sleeved on the outside of the support rod 1, and the rotating shaft 9 is used as the rotating support shaft. The rotating shaft 9 is directly inserted into the adjusting hole and the rotating frame 6. This connection method is simple, effective and easy to operate.

[0052] A sleeve 5 is fixed to the outside of the adjustment hole 4 by a pin, and a rotating shaft 9 is fixed on both sides of the outer wall of the sleeve 5. Through holes for inserting the rotating shaft 9 are opened on both sides of the rotating frame 6. The rotating frame 6 is sleeved on the outside of the sleeve 5, and the rotating shaft 9 is used as a rotating support shaft. The sleeve 5 is used as a support for the rotating shaft 9. Compared with directly inserting the rotating shaft 9 into the adjustment hole 4, the wear of the adjustment hole 4 can be reduced, because the sleeve 5 is limited by two adjustment holes 4 and can share the force.

[0053] The upper half of the sleeve 5 is provided with two through-holes extending therethrough, and a limit pin 10 is inserted into the through-holes and the adjustment hole 4. The limit pin 10 is U-shaped, and a buckle 11 is provided at each open end of the limit pin 10. The limit pin 10 secures the sleeve 5 to the strut 1, achieving a detachable connection of the sleeve 5 and facilitating adjustment of the position of the sleeve 5 on the strut 1. The U-shaped limit pin 10 provides more stable positioning and is also easy to remove. The buckle 11 is an iron piece that is clamped to the open end of the limit pin 10 and is used to prevent the limit pin 10 from separating from the sleeve 5 and the strut 1 when the limit pin 10 is working.

[0054] An external thread is provided on the outer wall of the limit rod 2, and a threaded sleeve is provided on the outside of the limit rod 2. Fixed shafts are provided on the upper and lower outer walls of the threaded sleeve, and a guide wheel 14 is provided at one end of the fixed shaft. The circumferential outer wall of the guide wheel 14 abuts against one side of the outer wall of the hatch cover. Locking nuts are provided at both ends of the threaded sleeve on the outer wall of the limit rod 2. By installing the guide wheel 14 on the limit rod 2, the entire tooling can be easily translated along the installation direction of the rubber strip when the rubber strip is installed, thereby improving work efficiency.

[0055] The short arm 8 is L-shaped, and the short arm includes a long side and a short side. A pressure block 15 is provided at the top of the short side, and one end of the long side is fixedly connected to the outer wall of one end of the rotating frame 6. The L-shaped design of the short arm 8 makes it convenient for the pressure block 15 to squeeze the rubber strip.

[0056] There are through strip grooves 16 on both sides of the rotating frame 6, and the rotating shaft 9 is inserted into the strip grooves 16. Through the design of the strip grooves 16 on the rotating frame 6, the position of the rotating support shaft of the rotating frame 6 can be adjusted in a small range, thereby adjusting the position of the short arm 8 so that the pressure block 15 can cover the entire width of the rubber strip.

[0057] In this embodiment, in order to meet the needs of on-board construction and dock cradle construction, the designed clamp can be quickly converted into a jacking mode. In the jacking mode, one side of the pad 13 is placed on the ground, and the rotating frame 6 is flipped 180 degrees so that the top surface of the pressure block 15 faces upward. Also according to the principle of leverage, the staff continuously lifts and presses the long arm 7 to press the rubber strip into the rubber strip installation groove through the pressure block 15, thereby reducing labor intensity and improving work efficiency.

[0058] Since the thickness of hatch covers of different ship types is different, the adjustable shaft method can adjust the height of the rotating frame 6 on the strut 1 by adjusting the hole 4 and cooperating with the latch-type rotating shaft 9, thereby adjusting the size of the clamp opening to adapt to hatch covers of different thicknesses.

[0059] The entire device can be used for the installation of sealing rubbers for hatch covers of the lifting type, side-sliding type, and folding type. It has a wide range of applications and basically meets the requirements for installing rubber strips on hatch covers under various working conditions. It reduces the conditions for replacing rubber strips on hatch covers and the total cost of replacing rubber strips, which can greatly reduce the labor intensity of workers and improve work efficiency.

[0060] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
