Description

Technical Field

[0001] The utility model relates to the technical field of ship lock gate maintenance, in particular to a device for removing a top pivot pull seat shaft of a ship lock gate. Background Art

[0002] Inland river locks have a high volume of traffic, and maintenance periods are very short, typically around 30 days. Repairs to the gate's top pivot often require the entire top pivot rod to be removed. This requires removing not only the top pivot shaft but also the top pivot seat shaft.

[0003] The top pivot pull seat shaft is located at the end of the top pivot slot and at the bottom. The limited space and stress conditions make it very difficult to remove quickly, significantly impacting the construction schedule. Because the pull seat shaft does not rotate during gate operation, it often rusts over a single operating cycle. Furthermore, the stress can cause it to lock with the pull rod, making it extremely difficult to remove.

[0004] Unlike the top pivot removal process, specialized removal tools are required for this location. Top pivot repair, a critical process in gate construction, is a prerequisite for the smooth execution of subsequent steps. Rapidly removing the pull seat shaft and fully removing the top pivot rod is crucial to ensuring the smooth execution of the gate project and even the overall construction schedule. Existing technologies typically utilize simple, cumbersome tools, lacking a dedicated auxiliary removal tool to significantly improve the efficiency of this process. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figure 1-3A device for removing the shaft of the top pivot seat of a ship lock gate comprises a full-thread screw 1 and a nut 2. The nut 2 is threadedly connected to the full-thread screw 1. The full-thread screw 1 is about 0.8 to 1.2 meters long, generally 1 meter long. A bearing frame 3 is provided on the full-thread screw 1. A handle 7 is provided on the upper side of the bearing frame 3 to facilitate the transport and movement of the bearing frame 3. The bearing frame 3 is in the shape of a long strip. The full-thread screw 1 passes through the bearing frame 3 and is movably connected therebetween to facilitate storage and carrying. The nut 2 is arranged on the upper side of the bearing frame 3. The height of the nut 2 can be freely adjusted depending on the size of the top pivot seat of the ship lock gate at the construction site. The height of the carrier 3 is determined by a jack 4 provided on the lower side of the carrier 3. A hydraulic jack is generally used. Two groups of jacks 4 are provided, one on each side of the full-thread screw 1. The upper part of the jack 4 is pressed against the carrier 3, and the carrier 3 is stably lifted from both sides of the full-thread screw 1. A mounting groove 31 is provided at the bottom of the carrier 3, and a mounting block 41 is provided on the top of the jack 4. The mounting block 41 is slidably connected to the mounting groove 31, which facilitates adjustment of the position of the jack 4 to adapt to the working environment and avoid obstacles. The jack 4 is detachably connected to the carrier 3, which is convenient for installation and removal and easy to carry.

[0022] A welding head 5 is provided at the lower end of the full-thread screw 1 for welding the top of the top pivot pull seat shaft to improve the drawing reliability. A connecting sleeve 6 is provided between the full-thread screw 1 and the welding head 5. The connecting sleeve 6 is threadedly connected to the full-thread screw 1, which facilitates the rapid replacement of the welding head 5, thereby increasing the service life of the equipment and facilitating maintenance.

[0023] A screw positioning shaft 11 is provided at the bottom of the full-thread screw 1, and a welding head positioning shaft 52 is provided at the top of the welding head 5. The screw positioning shaft 11 and the welding head positioning shaft 52 are offset against each other, and the screw positioning shaft 11 and the welding head positioning shaft 52 are adapted to each other and are both D-type shafts, realizing circumferential rotation positioning and constraint to avoid relative rotation between the full-thread screw 1 and the welding head 5. A shoulder 51 adapted to the connecting sleeve 6 is provided on the welding head 5 to limit axial movement between the full-thread screw 1 and the welding head 5. A welding groove 53 is provided at the bottom of the welding head 5 to improve the welding reliability of the top pivot pull seat shaft.

[0024] In this embodiment, the welding head 5 is welded to the top of the top pivot pull seat shaft, and the welding head 5 is installed on the full-thread screw 1 through the connecting sleeve 6. The connection and fixation between the full-thread screw 1 and the welding head 5 are achieved through the screw positioning shaft 11 and the welding head positioning shaft 52 to ensure a rigid connection;

[0025] On the lower side of the carrier frame 3, the jack 4 is installed through the mounting block 41 and the mounting slot 31. The position of the jack 4 is adjusted according to the gate environment. The full-thread screw 1 passes through the carrier frame 3 and is tightened through the nut 2. The upper and lower ends of the jack 4 are respectively against the carrier frame 3 and the top pivot seat. Pressure is applied to lift the carrier frame 3, thereby driving the full-thread screw 1 to move upward and pull the top pivot seat shaft. During this period, the jack 4 and the nut 2 are continuously adjusted to ensure that the top pivot seat shaft is quickly pulled out to improve maintenance efficiency. After dismantling is completed, the weld can be cut and the welding head 5 can be reused to reduce the cost of use.
