Description

Technical Field

[0001] The utility model belongs to the technical field of the disassembly of parts of a toothed coupling for a ship lock, and particularly relates to a toothed coupling disassembly device. Background Technique

[0002] The opening and closing actions of the miter gates of large high-head ship locks are realized by miter gate hoisting machines.

[0003] The miter gate hoisting machines are mainly divided into two types: hydraulic hoisting machines and mechanical hoisting machines. The hydraulic hoisting machine mainly realizes the opening and closing functions of the miter gate under static water conditions through the reciprocating movement of hydraulic cylinders. The mechanical hoisting machine has a relatively complex structure. The miter gate hoisting machine of a certain large high-head ship lock is a four-link mechanical hoisting machine, which is composed of a motor, an elastic sleeve pin coupling, an electro-hydraulic block brake, a horizontal reducer, a toothed coupling, a vertical reducer, an open gear pair, a crank and a push-pull rod.

[0004] As a connecting component between the horizontal reducer and the vertical reducer, the toothed coupling has a long working time and high stability requirements, and it needs to be disassembled and overhauled regularly to check the damage of the gears and replace the seals. To ensure the stability of the operation of the toothed coupling, an interference fit is adopted between the internal gear sleeve and the bevel gear shaft, which makes it difficult to disassemble. At present, there is no special device to facilitate the disassembly of the internal gear sleeve and the bevel gear shaft of the toothed coupling. Content of the Utility Model

[0005] In order to solve the above technical problems, the purpose of the utility model is to provide a toothed coupling disassembly device, which can realize the convenient removal of the internal gear sleeve and the bevel gear shaft, simple operation and safe construction.

[0006] In order to realize the above technical features, the purpose of the utility model is realized as follows: a toothed coupling disassembly device includes a locking nut, a base device, a connecting screw rod, a hoop device and a connecting bolt; the hoop device is installed on the internal gear sleeve of the toothed coupling, one end of multiple groups of connecting screw rods is connected with the hoop device through threads, and the other end passes through the bolt through-hole part of the base device and is fixed with a locking nut to ensure the locking of the hoop device end; the position of the base device end can be adjusted integrally to be suitable for different models of electric hydraulic jacks, and the electric hydraulic jacks are arranged between the base device and the internal gear sleeve.

[0007] There are 12 groups of the connecting screw rods in total.

[0008] The base device includes a bottom plate, a transverse reinforcing rib, a longitudinal reinforcing rib, a bolt through-hole, a top sealing plate, an inclined sealing plate and a side sealing plate;

[0009] Multiple transverse reinforcing ribs and longitudinal reinforcing ribs are welded on the bottom plate according to a ratio;

[0010] The top surface, bottom surface, inclined surface and side surface of the base device are respectively welded with a top sealing plate, an inclined sealing plate and a side sealing plate, thereby ensuring the sealing of the entire base device;

[0011] A plurality of bolt through holes are arranged on the bottom plate in proportion, so that the connecting screw rod can pass through the base device, and constraints are applied through the locking nut to adjust the position of the base device.

[0012] The number of the transverse reinforcing ribs and the longitudinal reinforcing ribs is 3 each.

[0013] The number of the bolt through holes is 12.

[0014] The hoop device includes a hoop, threaded holes and bolt holes;

[0015] There are two hoops in total, and the inner gear sleeve of the toothed coupling is locked by the two hoops. The hoops are connected by connecting bolts through the bolt holes. A plurality of threaded holes are arranged on the hoops. The positions of the threaded holes are concentric with the bolt through holes on the base device and are threadedly connected with the connecting screw rod, so that the hoop device and the base device form an integral body.

[0016] The number of the threaded holes is 12.

[0017] The utility model has the following beneficial effects:

[0018] 1. By setting a complete set of toothed coupling disassembly device and using a large-tonnage multi-stage electric hydraulic jack as the power source, the resistance generated by the interference fit between the inner gear sleeve and the bevel gear shaft can be effectively overcome, so as to achieve the purpose of disassembling the toothed coupling.

[0019] 2. By setting a complete set of toothed coupling disassembly device, by erecting a multi-stage electric hydraulic jack and adjusting the length of the hydraulic hose, the operator can stay away from the working position of the equipment, so that the safety guarantee during the disassembly of the toothed coupling is effectively improved.

[0020] 3. By arranging bolt through holes on the base device, the distance between the base device and the toothed coupling can be adjusted by adjusting the position of the locking bolts, so as to achieve the effect that multi-size and multi-tonnage electric hydraulic jacks are all applicable.

[0021] 4. By designing the toothed coupling disassembly device as an assembled type, it can meet the classified storage of each equipment and effectively improve the space utilization rate of the equipment. Description of the Drawings
