Description

Technical Field

[0001] The utility model relates to the technical field of butt joint plate welding construction in the plane stage during ship welding, and particularly relates to a ratchet type welding operation butt joint locking tool. Background Technique

[0002] In the ship manufacturing industry, during the butt joint plate construction in the plane stage, the traditional method is to weld baffles on an iron platform multiple times and manually cooperate with a crowbar to slowly move the steel plate to the welding position and then weld the steel plate. This welding method not only requires manual cooperation and complex operations during the welding process, but also causes weld scars and crowbar marks on the steel plate. After welding, it also requires manual labor, grinding, and repair welding, which is time-consuming and laborious.

[0003] Currently, there is an urgent need for a locking tool suitable for the ship plane welding stage, which can pull, butt joint, and lock two steel plates to be welded through the tool, avoiding manual operation and facilitating the welding operation. Summary of the Invention

[0004] In order to solve the above technical problems and be able to use machinery to pull, butt joint, and lock two steel plates to be welded, making the ship plane welding operation simple and improving the efficiency, the utility model provides a ratchet type welding operation butt joint locking tool, which is characterized in that it includes a left support pipe, a right support pipe, and a ratchet fixedly arranged between the left support pipe and the right support pipe. A left lead screw and a right lead screw are respectively threadedly connected to the inside of the left end of the left support pipe and the inside of the right end of the right support pipe. The left lead screw and the right lead screw can respectively rotate inside the left support pipe and the right support pipe to perform telescopic movement, and the thread directions of the left lead screw and the right lead screw are opposite. The left lead screw is a left-handed thread lead screw, and the right lead screw is a right-handed thread lead screw.

[0005] At the ends of the left lead screw and the right lead screw, tension plates are connected, and the tension plates are fixed on the surfaces of two steel plates to be welded during use.

[0006] A detachable ratchet wrench is sleeved on the ratchet. Rotating the ratchet wrench can drive the ratchet to rotate, and then drive the left support pipe and the right support pipe to rotate, retract the left lead screw and the right lead screw into the left support pipe and the right support pipe, thereby driving the tension plates to displace inwards, realizing the function of tightening two steel plates to be welded.

[0007] The ratchet is fixedly sleeved and welded on a ratchet sleeve. The left end of the ratchet sleeve is welded to the left support pipe, and the right end is welded to the right support pipe, that is, the ratchet is fixedly connected to the left support pipe and the right support pipe and does not need to be disassembled.

[0008] The ratchet wrench includes a circular ratchet sleeve at the top and a wrench handle at the lower part. The ratchet sleeve and the wrench handle are integrally formed. The inner diameter of the right opening of the ratchet sleeve is the same as the outer diameter of the ratchet. A retaining ring is provided on the left side surface of the ratchet sleeve. The outer edge of the retaining ring is welded to the inner edge of the left side surface of the ratchet sleeve. The inner diameter of the retaining ring is smaller than the outer diameter of the ratchet and larger than the outer diameter of the ratchet sleeve. After the ratchet wrench is sleeved into the left end of the left support pipe and moved to the right until the right opening of the ratchet sleeve is sleeved around the ratchet, at this time, the retaining ring on the left side surface of the ratchet sleeve is blocked by the left side surface of the ratchet, so that the ratchet sleeve cannot continue to move to the right.

[0009] On the outer side of the left side surface of the ratchet sleeve, a fixing nut is further provided. The fixing nut is screwed tightly on the ratchet sleeve through threads. The fixing nut is used to limit the leftward displacement of the ratchet sleeve.

[0010] A hollow pawl installation groove is provided inside the top end of the wrench handle, and a pawl is installed inside. The lower part of the ratchet sleeve is provided with a pawl through hole. The pawl passes through the pawl through hole and is connected to the ratchet inside the ratchet sleeve.

[0011] The lower end of the wrench handle is connected with a folding handle. The folding handle and the lower end of the wrench handle are pivotally connected through a handle connecting shaft. A fixing nut is installed between the folding handle and the wrench handle. After the fixing nut is loosened, 90-degree folding of the folding handle can be realized.

[0012] An anti-slip sleeve is installed at the lower end of the folding handle.

[0013] The pawl is fixed in the pawl installation groove by a press riveting fixing shaft. A pawl steel ball and a spring are installed below the pawl. The upper end of the spring presses the pawl steel ball against the pawl, and the lower end of the spring supports on the inner bottom surface of the pawl installation groove.

[0014] The utility model has the following advantages:

[0015] 1. It enables the flat-stage joint plate work and the steel plate welding work to use machinery to pull, butt and lock two steel plates to be welded. The operation is simple, the labor is reduced, and the efficiency is improved.

[0016] 2. The handle can be folded (for convenient use) and detached (for convenient transportation and storage).

[0017] 3. The ratchet wrench is convenient for disassembly and convenient for maintenance.

[0018] 4. The ratchet and the support pipe are designed as a whole, improving the overall stability of the support pipe. Description of the Drawings
