Abstract
The utility model discloses a practical tool of adjustment round pin axle, it relates to an instrument of adjustment round pin axle. The device comprises a rotating handle, a connecting plate and cylindrical pins, wherein the cylindrical pins are arranged at two ends of one side of the connecting plate, and the rotating handle is connected with the center of the other side of the connecting plate; the tail end of the rotating handle is vertically provided with a handle. The utility model has the advantages of reasonable design, convenient operation is reliable, has saved time and cost, and the practicality is strong, solves adjustment pin axle adjustment and dismouting difficulty problem.
Description
Technical Field
The utility model relates to an adjustment tool, concretely relates to adjustment pin axle's practical tool.
Background
In order to correct the lateral deviation generated in the assembling and using processes of the telescopic boom of a certain crane, manufacturers generally arrange adjusting pin shafts at two sides of the outer boom symmetrically. The outer diameter of the pin shaft is provided with threads, the outer end face of the pin shaft is provided with 2 threaded holes, and the three-dimensional structure of the pin shaft is shown in figure 1. When the inner suspension arm deviates laterally, the inner suspension arm can be corrected by adjusting the relative positions of the left and right side adjusting pin shafts. If the inner hanging arm deviates to the left side, the left side adjusting pin shaft can be screwed inwards; if the inner hanging arm deviates to the right side, the right side adjusting pin can be screwed inwards. The inner boom is offset to the left as shown in fig. 2a, and the inner boom adjusted by the pin is shown in fig. 2 b. In the past, no special tool is used for adjusting the pin shaft, and the pin shaft is usually screwed in by 2 screw rods and then rotated by another stressing rod. The operation method is time-consuming and labor-consuming, and easily causes bolt damage and loss.
To sum up, the utility model designs a practical tool of adjustment round pin axle.
Disclosure of Invention
The utility model aims at providing a practical tool of adjusting pin axle, structural design is reasonable, and convenient operation is reliable, has saved time and cost, and the practicality is strong, solves adjusting pin axle adjustment and dismouting difficulty problem.
In order to achieve the above purpose, the present invention is realized by the following technical solution: a practical tool for adjusting a pin shaft comprises a rotating handle, a connecting plate and cylindrical pins, wherein the cylindrical pins are arranged at two ends of one side of the connecting plate, and the rotating handle is connected with the center of the other side of the connecting plate; the tail end of the rotating handle is vertically provided with a handle.
Preferably, the cylindrical pin is matched with the adjusting pin shaft.
The utility model has the advantages that: the utility model has the advantages of reasonable design, reduced the time of dismouting bolt (save about 2 min), reduced the cost that the dismouting in-process produced because of the bolt damage. The special tool is simple and convenient to operate and high in working efficiency.
Drawings
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments;
FIG. 1 is a three-dimensional structure of a conventional pin (A, threaded hole at the end; B, external thread)
FIG. 2a is a schematic diagram of the leftward deviation of the inner boom (inner boom C, outer boom D, adjustment pin E);
FIG. 2b is a schematic view of the inner boom being offset to the left;
fig. 3 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
Referring to fig. 3, the following technical solutions are adopted in the present embodiment: a practical tool for adjusting a pin shaft comprises a rotating handle 1, a connecting plate 2 and cylindrical pins 3, wherein the cylindrical pins 3 are arranged at two ends of one side of the connecting plate 2, and the rotating handle 1 is connected with the center of the other side of the connecting plate 2; the handle 4 is vertically arranged at the tail end of the rotating handle 1.
The dismounting or adjusting method of the adjusting pin shaft of the embodiment is as follows: firstly, two cylindrical pins 3 are inserted into two threaded holes of the adjusting pin shaft, then a handle on the rotating handle 1 is held, and then the adjusting pin shaft is rotated through the rotating handle 1, so that the assembling and disassembling or adjusting work of the adjusting pin shaft can be completed.
By using the cylindrical pin tool, the time for dismounting the bolt is reduced (about 2min is saved), and the cost caused by the damage of the bolt in the dismounting process is reduced. The special tool is simple and convenient to operate and high in working efficiency.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
