Technical Field

[0001] This utility model relates to the field of mud gate cylinder pin technology, and in particular to a traction-type mud gate cylinder pin device. Background Technology

[0002] A mud gate is a structure used on dredgers to unload mud. It is usually located at the bottom of the hull and the mud is unloaded directly when the mud gate is opened. In the prior art, to solve the problem of maintaining the high pressure of the high-pressure oil pump of the mud gate cylinder hydraulic system during navigation, the mud gate cylinder is generally positioned by manually pushing the mud gate cylinder positioning pin.

[0003] However, the mud-gate hydraulic cylinder pin is heavy, requiring one person to push on one side and another to pull on the other to insert or remove the pin. This results in high labor intensity for workers, time-consuming and labor-intensive operation, low work efficiency, and high labor costs. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a traction-type mud gate cylinder pin device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A towing-type mudgate cylinder pin device includes a sleeve fixed to the deck, and further includes:

[0007] The support base includes a main support plate and a secondary support plate respectively disposed on both sides of the sleeve, and both the main support plate and the secondary support plate are provided with slots.

[0008] The socket is formed on the sleeve, and the bottom walls at both ends of the socket are flush with the support surfaces of the main support plate and the secondary support plate, respectively.

[0009] The pin body passes through the insertion hole and slides on the support seat, and is used to position the piston rod of the mud cylinder inside the sleeve.

[0010] And a traction unit, which is detachably mounted on either side of the support base via a slot, for pulling the pin body to slide on the support base.

[0011] Preferably, the traction unit includes a housing that engages with the slot, a drum rotatably connected within the housing, a pull rope wound around the drum, and a gear drive for driving the drum to rotate and wind up the pull rope. The end of the pull rope away from the drum is connected to the pin body.

[0012] Preferably, the outer shell includes a U-shaped shell and square blocks fixed on both sides of the U-shaped shell, the square blocks being snapped into slots.

[0013] Preferably, the free end of the pull rope away from the drum is connected to a hook, and the pin body is fixed with a pull ring that is hooked and connected to the hook.

[0014] Preferably, the gear drive includes a drive rod rotatably connected to the housing, a rotating handle disposed at the end of the drive rod, a small gear disposed on the drive rod, and a large gear disposed on the drum and meshing with the small gear.

[0015] Preferably, the pull rope is made of steel wire rope, and the surface of the pin body is provided with a polytetrafluoroethylene wear-resistant coating.

[0016] Compared with the prior art, this utility model provides a traction-type mud gate cylinder pin device, which has the following beneficial effects:

[0017] 1. This traction-type mud gate cylinder pin device uses a drive unit to rotate the drum to wind up the pull rope, which in turn pulls the pin body. This method is time-saving and labor-saving, improves the work efficiency of workers, and reduces labor costs.

[0018] 2. The traction-type mud gate cylinder pin device sets the gear drive component to mesh with a small gear and a large gear, thereby driving the drum connected to the large gear to rotate, meeting the high torque requirements, realizing labor-saving low-speed transmission, and reducing the labor intensity of workers.

[0019] 3. The traction-type mud gate cylinder pin device uses a square block to engage the outer casing in a slot, so that when the gear transmission component drives the drum to rotate, the outer casing will not rotate with the drum, thus ensuring the normal operation of the pin body traction work.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0028] like Figures 1 to 4 As shown, this embodiment proposes a traction-type mudgate cylinder pin device, including a sleeve 1 fixed on the deck, and further including: a support base 2, a insertion hole 3, a pin body 5, and a traction part 6. The support base 2 includes a main support plate 201 and a secondary support plate 202 respectively disposed on both sides of the sleeve 1. The main support plate 201 and the secondary support plate 202 are each provided with a slot 4. The insertion hole 3 radially penetrates the side wall of the sleeve 1, and the bottom walls of the openings at both ends of the insertion hole 3 are flush with the support surfaces of the main support plate 201 and the secondary support plate 202 respectively. The pin body 5 penetrates the insertion hole 3 and slides on the support base 2 for positioning the piston rod of the mudgate cylinder inside the sleeve 1; and the traction part 6 is detachably installed on either side of the support base 2 through the slot 4 for traction of the pin body 5 to slide on the support base 2.

[0029] Furthermore, the traction unit 6 includes a housing 601 that engages with the slot 4, a drum 602 rotatably connected inside the housing 601, a pull rope 603 wound around the drum 602, and a gear drive for driving the drum 602 to rotate and wind the pull rope 603. The end of the pull rope 603 away from the drum 602 is connected to the pin body 5.

[0030] Specifically, when the pin body 5 needs to be moved out of the insertion hole 3, the operator engages the traction unit 6 in the slot 4 of the main support plate 201. By controlling the gear drive, the gear drive drives the drum 602 to rotate on the outer shell 601. The drum 602 winds up the pull rope 603, which transmits the pulling force to the pin body 5, moving the pin body 5 from the insertion hole 3 to the main support plate 201. When the pin body 5 needs to be moved from the main support plate 201 into the insertion hole 3 for the limit locking work of the mud gate cylinder, the traction unit 6 is switched from the slot 4 of the main support plate 201 to the slot 4 of the auxiliary support plate 202. The gear drive drives the drum 602 to wind up the pull rope 603, achieving the traction displacement of the pin body 5. The operation is time-saving and labor-saving, which can improve the work efficiency of the operator and reduce labor costs. Moreover, there is no need to add an extra cylinder or hydraulic cylinder to drive the pin, further reducing costs.

[0031] It should be noted that, in order to prevent the gear drive from rotating and causing the outer shell 601 to rotate, the outer shell 601 includes a U-shaped shell 6011 and square blocks 6012 fixed on both sides of the U-shaped shell 6011, so that the square blocks 6012 are engaged in the slot 4 to limit the outer shell 601. One end of the slot 4 is provided with an opening to facilitate the quick movement of the square blocks 6012 in or out.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, a hook 6031 is connected to the free end of the pull rope 603 away from the drum 602, and a pull ring 501 that is hooked and connected to the hook 6031 is fixed on the pin body 5; by hooking and cooperating with the hook 6031 and the pull ring 501, the staff does not need to tie the free end of the pull rope 603 to the pin body 5, which effectively improves the work efficiency of the staff.

[0033] like Figure 3 and Figure 4As shown, in a preferred embodiment, based on the above method, the gear drive component further includes a drive rod 7 rotatably connected to the housing 601, a rotating handle 701 disposed at the end of the drive rod 7, a small gear 702 disposed on the drive rod 7, and a large gear 703 disposed on the drum 602 and meshing with the small gear 702; the gear drive component is configured to mesh and transmit power between the small gear 702 and the large gear 703, thereby driving the drum 602 connected to the large gear 703 to rotate, meeting the high torque requirement, realizing labor-saving low-speed transmission, and reducing the labor intensity of workers.

[0034] like Figure 1 As shown, in a preferred embodiment, based on the above method, the pull rope 603 is further made of steel wire rope, and the surface of the pin body 5 is coated with polytetrafluoroethylene wear-resistant coating; the steel wire rope has high breaking strength and can withstand high loads in repeated traction operations, avoiding the risk of breakage and ensuring stable and reliable insertion and extraction processes; the galvanized steel wire rope has excellent corrosion resistance in humid and salt spray marine environments and is not prone to rusting after long-term use; its flexibility also takes into account fatigue resistance, making it suitable for high-frequency retrieval and release operations; polytetrafluoroethylene has an extremely low coefficient of friction, which can significantly reduce the sliding resistance of the pin body 5 during movement.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
