Description

Technical Field

[0001] This new type belongs to special tools, and specifically relates to a special tool for installing the internal gear shaft in a transfer machine. Background Technique

[0002] A total of two transfer machines are set in the out-of-pile refueling system. One is the transfer room transfer machine, which is installed in the transfer room and is used to transfer new components from the new component conversion barrel to the lifting bucket of the in-pile charging elevator, and to transfer spent components from the lifting bucket of the in-pile discharging elevator to the spent component conversion barrel. The other is the cleaning room transfer machine, which is installed in the cleaning room and is used to transfer spent components.

[0003] Before installing the rotating shaft of the transfer machine, the internal gear shaft needs to be inserted into the gripper and the rack transmission device. Before inserting the internal gear shaft, it is necessary to check whether the key, internal gear, etc. are installed in place. The external shape of the internal gear shaft is a stepped shaft with a relatively small change in shaft diameter. The installation position is narrow, and the unilateral clearance is about 7 mm. It is impossible to place the internal gear shaft in the installation hole by clamping, and when the internal gear shaft is in the installation position state, there is no lifting lug installation hole or other structure on the upper end face, so it is impossible to place the internal gear shaft in the installation hole through the upper end face. Therefore, this task cannot be completed in the conventional way. Content of the Utility Model

[0014] In the figure: 1, inner pliers handle; 2, outer pliers handle; 3, locking nut; 4, locking bolt; 5, connecting pin shaft; 6, embedded chuck; 7, lock pin Detailed Implementation Modes

[0015] A special tool for installing the gear shaft in a transfer machine, the device includes: inner pliers handle 1, outer pliers handle 2, locking nut 3, locking bolt 4, connecting pin shaft 5, embedded chuck 6, lock pin 7; the inner pliers handle 1 is cooperatively installed with the outer pliers handle 2 through the connecting pin shaft 5; the locking nut 3 is cooperatively installed with the locking bolt 4; the embedded chuck 6 is respectively welded to the inner pliers handle 1 and the outer pliers handle 2.

[0016] Further, the connecting pin shaft 5 is respectively connected through the pin shaft holes on the inner pliers handle 1 and the outer pliers handle 2, and the inner pliers handle 1 forms the maximum distance with the outer pliers handle 2 through its own limit boss, and uses the lever principle to ensure that the maximum angle is formed between the lower parts of the inner chuck 1 and the outer pliers handle 2.

[0017] Further, the locking bolt 4 is respectively cooperated with the locking nut 3 through the bolt holes on the inner pliers handle 1 and the outer pliers handle 2, and locks the maximum distance formed by the limit boss of the inner pliers handle 1 and the upper part of the outer pliers handle 2.

[0018] Further, the embedded chuck 6 is respectively welded to the lower parts of the inner pliers handle 1 and the outer pliers handle 2, the thickness of the embedded chuck 6 is 5 mm, which is less than the width of the relief groove of the internal gear shaft of 8 mm, and the maximum diameter of the embedded chuck 6 is the same as the inner diameter of the relief groove of the internal gear shaft.

[0019] Further, there is a lock pin 7 on the locking bolt 4.

[0020] A specific example is given below.

[0021] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments will be clearly and completely described below in combination with the installation process of the internal gear shaft in the transfer machine. The described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0022] It should be understood that the orientation and positional relationships indicated by terms such as "upper" and "lower" are based on the orientation or positional relationships shown in the figures, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the components referred to must have a specific orientation. Therefore, it should not be construed as a limitation to this application.

[0023] As Figure 1 shown, the inner clamp handle 1 and the outer clamp handle 2 are respectively welded to the embedded chuck 6 according to the designed shape, and the connecting pin shaft 5 connects the inner clamp handle 1 and the outer clamp handle 2 through the pin hole.

[0024] Step 1: Before installing the internal gear, separate the upper parts of the inner clamp handle 1 and the outer clamp handle 2 to make the lower parts form the minimum distance.

[0025] Step 2: Insert the special tool, the embedded chuck 6, into the internal gear until it reaches the position of the relief groove.

[0026] Step 3: Combine the upper parts of the inner clamp handle 1 and the outer clamp handle 2, and make the lower parts of the inner clamp handle 1 and the outer clamp handle 2 form the maximum distance through their own limit bosses, that is, clamp the outer edge of the embedded chuck 6 at the position of the relief groove.

[0027] Step 4: Pass the locking bolt 4 through the bolt holes on the inner clamp handle 1 and the outer clamp handle 2, install the locking nut 3, and install the anti-loosening pin 7.

[0028] Step 5: Pass the lifting belt through the lifting holes on the upper parts of the inner clamp handle 1 and the outer clamp handle 2, and connect the sling.

[0029] Step 6: After hoisting in place, remove the sling and the special tool, and the hoisting work is completed.

[0030] Through the structural analysis of the internal gear shaft and in combination with the actual on-site installation conditions, this application utilizes the relief groove below the internal gear shaft, whose diameter is 16 mm larger than the pitch circle diameter of the gear teeth, that is, the depth of the relief groove is 8 mm. Therefore, using the lower end face of the gear as the support surface, a set of special tools is designed for the installation of the internal gear shaft. Using this special tool solves the problem that it is impossible to hoist in place due to the narrow installation space, and greatly improves the construction efficiency of the team.
