Detailed Description
The following description of the preferred embodiments of the present invention will be made in conjunction with the drawings and the accompanying drawings to further illustrate the technical means adopted to achieve the objects of the present invention.
With reference to fig. 1 to 4, the device for pulling out pins of the present invention comprises: a body part 1, a body sliding part 2 and a pin connecting part 3; wherein,
the body part 1 is of a vertical columnar structure, the top end of the body part is provided with a detachable impacted part 10, and the bottom end of the body part is provided with a pin connecting part 3;
the body sliding part 2 is provided with a through hole, the size of the through hole is matched with the cross section of the body part 1, and the body sliding part 2 can slide up and down along the body part 1;
the pin connecting part 3 is used for connecting a pin 4 to be pulled;
when the pin is pulled out, the body sliding part 2 impacts the impacted part 10 at the top end of the body part 1 to drive the pin connecting part 3, and the pin 4 to be pulled out is pulled out.
In this embodiment, when the device is not used, the body part 1, the impacted part 10, the body sliding part 2 and the pin connecting part 3 can be detached and separated for placement.
In the present embodiment, as shown in parts a, B, C, and D in fig. 3, the pin connection part 3 includes: a special pin connector 31, a special pin connector 32, a special pin connector 33 or a pin pulling pliers 34. The size of the lower part of the special pin connectors 31, 32 and 33 can correspond to access holes with different sizes of pins, and the size of the special pin connectors depends on the internal thread size of the access holes of the pins, such as M8 multiplied by 1 (the diameter of a thread bottom ruler is 8mm, the thread pitch is 1mm), M10 multiplied by 1 and M12 multiplied by 2 (unit: mm).
In one embodiment, the pins are generally classified as cylindrical pins and conical pins, and are of various sizes, such as: among the preferred sizes (unit: mm) are Φ 8, Φ 10, Φ 12, Φ 16, Φ 20, Φ 24, Φ 36, and the like.
The size of the access hole (internal thread) of the pin is mainly determined by the customized standard, and of course, most pins belong to special pins and are manufactured according to the particularity of the used place. Generally, the access hole of the pin with the diameter of 12 can be matched with an internal thread of M8 multiplied by 1, and the access hole of the pin with the diameter of 16 can be matched with M10 multiplied by 1, and the like.
The cooperation in pin and the round pin hole of taking the access hole generally adopts transition fit, the inconvenient occasion of tearing open of mainly used, for example when the round pin hole is the blind hole, at this moment adopt afterbody area round pin hole nail just very easy dismantlement, the pin has or not the access hole and the pin size relation is little. For example: the diameters of the servomotor connecting pins on the two sides of the water inlet valve of the water pump turbine reach 300mm, and only one small access hole is formed, so that the water pump turbine water inlet valve is mainly used for facilitating transportation. And for another example, a circle of pins (24) are pressed on the movable guide vane sleeve of the pump turbine, the size of the pins is generally phi 16, a section of pin head with the size of phi 20 is arranged at the tail part, and the internal thread of the pin head for arranging the access hole is M12 multiplied by 2.
As shown in part a of fig. 3 and fig. 4, the special pin connector 31 shows an upper internal thread for connecting with the trunk 1 and a lower external thread for connecting with the pin 4 to be pulled.
In other embodiments, the connection manner of the pin connection portion 3 and the trunk portion 1 is not limited to the threaded connection, and the present invention is not limited thereto.
In one embodiment, as shown in fig. 4, a special pin connector 31 can be installed at the bottom end of the trunk 1, and when a threaded access hole is provided on the pin 4 to be pulled out, the pin can be pulled out by the following method: firstly, the special pin connector 31 matched with the access hole is connected with the pin 4 to be pulled out, and then the impacted part 10 at the top end of the body part 1 is impacted through the body sliding part 2, so that the pin 4 to be pulled out is pulled out.
In another embodiment, as shown in fig. 5 and D of fig. 3, the pin connection portion 3 further includes: the pin pulling pliers 34 can be installed at the bottom end of the trunk part 1 and used for pulling out pins without access holes, and comprises a pliers 341 and a fastening rod 342;
as shown in fig. 5, first, the pin 4 to be extracted is gripped by the gripper 341 through the fastening rod 342, and then the pin 4 to be extracted is extracted by striking the struck portion 10 at the tip end of the trunk portion 1 through the trunk sliding portion 2.
In other embodiments, the pin remover 34 may also be used to remove pins with access holes, and the invention is not limited to the specific pin type of the pin remover 34.
In a specific embodiment, the utility model discloses a pull out pin nail isolated plant can cooperate the pulley 5 (or chain block) that overhauls the place top setting to use. As shown in fig. 6, one end of the cable is connected to the body sliding portion 2, and after the direction of the force applied is changed by the pulley 5, the other end pulls the body sliding portion 2 by a manual or mechanical force, thereby pulling out the pin 4 to be pulled out by striking.
In practical application, certain special maintenance place top has just set up portable chain block or pulley when the installation, the utility model discloses a pull out pin isolated plant can cooperate chain block or pulley to use, lets pull out pin work light convenient more.
For example, in modern hydroelectric power plants and pumped storage power plants, there are 1 to 2 planned minor repairs or major repairs to the power generating unit every year, and in order to facilitate the repairs of the turbine movable guide vanes, the turbine guide bearings, the main shaft seals, the related cooling devices, etc. (in the power plant repairs, where the repairs are important works), movable chain blocks (some block integrated by electric and hand) or movable pulleys are arranged on the top of the waterwheel chamber (the turbine movable guide vanes, the turbine guide bearings, etc. are all in the waterwheel chamber). When carrying out hydraulic turbine movable guide vane and changing (in the power station maintenance work), because movable guide vane generally is 24, guide vane sleeve upper end gland has 16-24 locking pins (total pin number is 384 and adds 576), need take out these pins very hard, if adopt the utility model discloses pull out the portable calabash of pin isolated plant cooperation waterwheel room or pulley and pull out these pins, it is convenient very light, and shorten the during operation greatly.
When the pull rope is used, the pull rope is fixed on the body sliding part 2 and quickly pulled up along the body part 3, the striking part 10 is struck to generate strong impact force, the pin 4 to be pulled out is quickly pulled out, and the pull rope can change the pulling force direction through the pulley aiming at a working place with maintenance conditions (such as a movable chain block and a pulley device above a water mill room of a power station), so that the fatigue of workers is reduced.
The utility model discloses a pin nail isolated plant utilizes the mode of removing the striking to produce powerful impact force, extracts the pin rapidly, simplifies the pin nail flow of pulling out to operation flow is simple, and the use face is wider, can be furnished with the pin connector of multiple model according to the pin of difference, can lay the basis for proposing automatic pin nail technical scheme of pulling out from now on.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
