Description

Technical Field

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

[0002] The mud gate pin is an important component of the dredging equipment on a dredger, related to the fixing, opening, and closing of the mud gate. The mud gate pin is a relatively heavy metal block, and the base on which the mud gate pin is placed is about 1.5 meters above the deck surface, a height that is difficult to exert force at.

[0003] The existing method of moving the hydraulic cylinder pin requires one person to push from one side and another person to pull from the other to insert or remove the pin. This results in high labor intensity, time-consuming and labor-intensive operation, low work efficiency, and high labor costs for the workers. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a rack and pinion type mudgate cylinder pin device.

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

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

[0007] A support base, which is fixed on the sleeve and is used to support the pin body, the support base includes a first support and a second support respectively disposed on both sides of the sleeve;

[0008] A positioning hole is provided on the sleeve, and the bottom wall of the positioning hole opening is flush with the support surface of the support base.

[0009] And the tooth condition, which is connected to the end of the pin body;

[0010] The first support is rotatably equipped with a drive gear that meshes with the toothed gear.

[0011] Preferably, a rotating rod is rotatably connected to the first support, the rotating rod is fixedly connected to the drive gear, and a rocker arm is fixedly provided at the end of the rotating rod.

[0012] Preferably, the tooth condition includes a rack plate vertically slidably connected to a first support and a swing rod movably connected between the rack plate and the pin body via a rotating shaft. The rack plate is meshed with a drive gear, and a limiting frame slidably connected to the rack plate is fixed on the first support.

[0013] Preferably, the first support and the second support have the same structure, both including a main frame body fixedly connected to the sleeve and a number of auxiliary wheels equidistantly arranged on the main frame body by means of pins.

[0014] Preferably, a reinforcing rib is fixed between the main frame and the outer wall of the sleeve.

[0015] Preferably, the surface of the pin body is provided with a polytetrafluoroethylene wear-resistant coating.

[0016] Compared with the prior art, the present invention provides a rack and pinion type mudgate cylinder pin device, which has the following advantages:

[0017] 1. This rack and pinion type mud gate cylinder pin device uses a drive gear and a gear mechanism to drive the pin body forward and backward. A single person can quickly insert and remove the pin body, saving time and effort, improving the work efficiency of workers and reducing labor costs.

[0018] 2. The rack-and-pinion mudgate cylinder pin device is designed so that the gears are movably connected by the rack plate and the swing rod. This allows the drive gear to mesh with the rack plate in the vertical direction, enabling the swing rod to drive the pin body to move horizontally. Without changing the structure of the pin body, this avoids the rack plate from being too long in the horizontal direction when the pin is pulled out due to horizontal meshing with the drive gear, which would affect the workers' activities on the deck, prevent workers from being injured by collisions, and ensure a safe working environment for the workers.

[0019] 3. The rack and pinion type mudgate cylinder pin device reduces the contact area between the pin body and the support seat by having the support seat contact the pin body through the auxiliary wheel, thereby reducing the resistance when the pin body and the support seat move. In addition, the auxiliary wheel rotates freely when the pin body moves, which changes the sliding friction into rolling friction, reducing the wear of the support seat and the pin body, improving the service life of the device, extending the maintenance cycle of the device, and thus reducing maintenance costs.

[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 rack and pinion type mudgate cylinder pin device, including a sleeve 2 fixed on the deck 1, and further including: a support 3, a positioning hole 5, and a gear condition 6. The support 3 is fixed on the sleeve 2 and is used to support the pin body 4. The support 3 includes a first support 301 and a second support 302 respectively disposed on both sides of the sleeve 2. The positioning hole 5 is opened on the sleeve 2, and the bottom wall of the opening of the positioning hole 5 is flush with the support surface of the support 3. The gear condition 6 is connected to the end of the pin body 4. Among them, a drive gear 7 that meshes with the gear condition 6 is rotatably disposed on the first support 301.

[0029] Specifically, the pin body 4 is placed on the support base 3 and inserted into the positioning hole 5 to limit the mud gate cylinder. By controlling the rotation of the drive gear 7, the drive gear 7 meshes with the gear condition 6, so that the gear condition 6 drives the pin body 4 to move forward and backward. A single person can quickly insert and remove the pin body 4, which saves time and effort, improves the work efficiency of the staff, and reduces labor costs.

[0030] It should be noted that, in order to facilitate the driving of the drive gear 7, a rotating rod 701 is rotatably connected to the first support 301. The rotating rod 701 is fixedly connected to the drive gear 7, and a rocker arm 702 is fixedly provided at the end of the rotating rod 701. By rotating the rocker arm 702, the operator can drive the drive gear 7 on the rotating rod 701 to rotate, thereby enabling the drive gear 7 to mesh with the gear condition 6 and realize the forward or backward movement of the pin body 4 on the support 3.

[0031] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the tooth condition 6 further includes a rack plate 601 vertically slidably connected to the first support 301 and a swing rod 602 movably connected between the rack plate 601 and the pin body 4 via a rotating shaft. The rack plate 601 is meshed with the drive gear 7, and a limiting frame 8 is fixed on the first support 301 and slidably connected to the rack plate 601.

[0032] The design of the tooth condition 6, which is movably connected by the rack plate 601 and the swing rod 602, allows the vertical meshing of the drive gear 7 with the rack plate 601 to achieve the horizontal displacement of the swing rod 602 driving the pin body 4. Without changing the structure of the pin body 4, this design avoids the situation where the rack plate 601 and the drive gear 7 mesh in the horizontal direction, causing the overall length of the rack plate 601 and the pin body 4 to be excessively long in the horizontal direction after the pin body 4 is pulled out, thus affecting the activities of the workers on the deck 1. This effectively avoids collision injuries to the workers and ensures a safe working environment for them.

[0033] like Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the first support 301 and the second support 302 have the same structure, both including a main frame 9 fixedly connected to the sleeve 2 and a plurality of auxiliary wheels 901 equidistantly arranged on the main frame 9 by means of pins; the support base 3 uses the auxiliary wheels 901 to contact the pin body 4, reducing the contact area between the pin body 4 and the support base 3, thereby reducing the resistance when the pin body 4 and the support base 3 move, and the auxiliary wheels 901 rotate freely when the pin body 4 moves, so that the sliding friction is converted into rolling friction, reducing the wear of the support base 3 and the pin body 4, improving the service life of the device, extending the maintenance cycle of the device, and thus reducing the maintenance cost.

[0034] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a reinforcing rib plate 10 is further fixed between the main frame 9 and the outer wall of the sleeve 2; the setting of the reinforcing rib plate 10 facilitates the improvement of the structural stability between the support base 3 and the sleeve 2, and avoids breakage and damage at the connection between the support base 3 and the sleeve 2.

[0035] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the surface of the pin body 4 is further provided with a polytetrafluoroethylene wear-resistant coating; polytetrafluoroethylene has an extremely low coefficient of friction, which can significantly reduce the sliding resistance of the pin body 4 during movement, reduce its wear degree, and ensure its service life.

[0036] 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.
