In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
a special tool for disassembling and assembling a coupling shaft of a ship lock anti-arc door comprises a left first positioning plate, a right first positioning plate, a front second positioning plate and a rear second positioning plate, wherein the first positioning plate and the second positioning plate are detachably connected to form a frame structure; a bracket is arranged in the frame structure, and an arc-shaped groove matched with the coupling shaft of the anti-arc door is arranged on the bracket; a jack is fixed on one side of the frame structure and is opposite to the coupling shaft of the anti-arc door.
The first positioning plates are of a square structure, and the front and the rear second positioning plates are arranged at intervals.
The first positioning plate is detachably connected with the second positioning plate through a bolt and a connecting plate.
The bracket comprises at least two groups of positioning plates with arc-shaped grooves, all the positioning plates are arranged side by side and are connected into a whole through a fixing plate, and the fixing plate is fixed or detachably connected with the frame structure.
The utility model relates to a special frock of lock anti-arc door allies oneself with door shaft dismouting has following technological effect: the first positioning plate and the second positioning plate are detachably connected through the bolt, so that the structure is greatly simplified on the premise of ensuring the tensile strength, and the first positioning plate and the second positioning plate are convenient to mount in place; two second locating plates on the width direction are bearing plates, a beam is added on the two second locating plates on one side of the bearing plates to improve the tensile strength, a bearing plate is added on the bearing plates to be used by a jack, and the bracket is used for locating the position of the coupling shaft of the anti-arc door when the anti-arc door is installed back. The device solves the problems that the disassembly and assembly of the coupling shaft of the conventional anti-arc door are long in time consumption, large in work difficulty, high in site danger and the like, is simple in structure, safe, reliable and convenient to construct, is convenient for quick disassembly and assembly during maintenance of the coupling shaft of the anti-arc door, shortens the maintenance time of the coupling shaft of the anti-arc door, and improves the maintenance efficiency of the ship lock.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is the schematic structural diagram of the coupling shaft of the middle anti-arc door of the present invention.
In the figure: the positioning device comprises a first positioning plate 1, a second positioning plate 2, a bolt 3, a bracket 4, a reverse arc door coupling shaft 5, a jack 6, a bearing plate 7, a shaft sleeve 8, a connecting plate 9, a positioning plate 10 and a fixing plate 11.
Detailed Description
As shown in fig. 1, a special tool for disassembling and assembling a coupling shaft of a ship lock anti-arc door comprises a left first positioning plate 1, a right first positioning plate 1, and a front second positioning plate 2 and a rear second positioning plate 2. The first positioning plate 1 is of a square structure, and two groups of connecting plates 9 with holes are welded on the left side and the right side of the first positioning plate 1 respectively. The connecting plate 9 facilitates the bolt-type connection between the first positioning plate 1 and the second positioning plate 2. The second positioning plate 2 is a simple rectangular plate body and is a bearing plate. The front and the rear second positioning plates 2 are two groups, and the two groups of second positioning plates 2 are arranged at intervals and detachably connected with the first positioning plate 1 through a connecting plate 9 and a bolt 3 to form a frame structure. The spacing distance between the two second positioning plates 2 on the same side is larger than the diameter of the reverse arc door coupling shaft 5, so that the reverse arc door coupling shaft 5 can be conveniently ejected or installed in the later period.
Install bracket 4 in the frame construction, bracket 4 includes two sets of locating plates 10 of taking the arc wall, and two locating plates 10 are arranged side by side and all link into a whole through fixed plate 11 from top to bottom, and fixed plate 11 can adopt the bolt can dismantle with frame construction and connect also bolted connection, also fixable connection. An arc-shaped groove is formed in one side of the positioning plate 10, the arc-shaped groove can be used for positioning the reverse arc door coupling shaft 5 conveniently in later-stage installation, and the shaft sleeve 8 can be jacked into the arc-shaped groove conveniently and quickly.
The working principle and the process are as follows:
disassembling: six plates of the left and right first positioning plates 1 and the front and rear second positioning plates 2 are connected through eight bolts 3 and surround the installation station where the reverse arc door connecting shaft 5 is located. The bottom of the jack 6 is arranged at the position of the bearing plate 7, and the jack 6 is fixed on the bearing plate 7 through the connecting plate. The other end of the jack 6 is arranged at the position of the reverse arc door coupling shaft 5 and is right opposite to the reverse arc door coupling shaft 5, and the shaft sleeve 8 at the position of the reverse arc door coupling shaft 5 is propped against the second positioning plate 2. The handle of the jack 6 is shaken, and the reverse arc door coupling shaft 5 overcomes the friction force between the reverse arc door coupling shaft and the shaft sleeve 8 to be ejected out of the shaft hole under the action of horizontal force.
And (3) repacking: the reverse arc door connecting shaft 5 is positioned through the bracket 4, and then the handle of the jack 6 is shaken to enable the reverse arc door connecting shaft 5 to overcome the friction force between the reverse arc door connecting shaft and the shaft sleeve 8 to be pushed into the shaft hole under the action of horizontal force.
