To mesh.

本願発明全体の機械作動順序は：
１、モーター２２を起動し、モーター２２が作動し伝動軸２１を駆動し回転させ、これによってスライド歯車５５が駆動されて回転し、スライド歯車５５と噛合するように連結された従動歯車１９が連動し回転し、そして従動軸２０と従動軸２０にある第二リール１７と第一リール１８が連動し回転し、第二リール１７と第一リール１８が回転することで第一引き紐３９と第二引き紐６１を引き、これによって二つの移動板３５が前後両側へ引かれ、ベース３６の内部構造が露出され、検査と修理に便利を与える。
２、昇降空間６２の前壁にある押しブロック４２と接触するまで前側の移動板３５が移動したとき、押しブロック４２が前方へ移動し細紐１５と紐４０を引き、引っ張られた細紐１５が位置制限台形ブロック１３を引き位置制限溝１２から離脱させ、移動ブロック１１が制限を失い固定軸３７で上下にスライドでき、紐４０が引っ張られてスライド歯車５５を右方へ引き動かし、スライド歯車５５が従動歯車１９との噛合状態から離脱し回転歯車２６と噛み合い、従動軸２０が回転を停止し、スライド歯車５５と噛合するように連結された回転歯車２６が回転し始める。
３、回転歯車２６が回転して回転軸２４と回転軸２４の右端にある第三リール２９及び第四リール３２を駆動し回転させ、これによって麻縄３０と電線３１がゆっくりと緩み、移動ブロック１１とベース３６が固定軸３７で下方へスライドし始め、ベース３６がプッシュブロック５７との接触状態から離脱したとき、プッシュブロック５７が自身の重力と伸縮ばね５９の弾力によって下方へ移動して二本の引き紐４７を緩め、二つの台形ブロック４４が引き紐４７の引く力を失って下方へ移動し二つの位置制限穴４８の中に入り、移動板３５が前記復帰ばね３８の作用によって復帰することは制限される。
４、ベース３６が検査と修理に適切な位置まで降下したときに、モーター２２を止め、検査と修理が終わったらモーター２２を逆回転させ、これによって第三リール２９と第四リール３２が逆回転し麻縄３０と電線３１をきつく繰り入れ、ベース３６が改めて上方へ引き動かされて復帰し、ベース３６の上端面が改めてプッシュブロック５７と当接し、これによって二本の引き紐４７が引っ張られ、引き紐４７によって二つの台形ブロック４４を上方へ引き動かして位置制限穴４８から離れさせ、二つの移動板３５が台形ブロック４４の制限を失って復帰ばね３８の弾力によって復帰し、二つの移動板３５は復帰する過程に第一引き紐３９と第二引き紐６１を引き動かし復帰させることができる。
５、前側の移動板３５が押しブロック４２から離れ、押しブロック４２が弾性ばね４３の作用によって右方へ移動し復帰し、細紐１５と紐４０が緩み、スライド歯車５５が紐４０の引く力を失って収縮ばね５４の作用によって左方へ移動し復帰し、位置制限台形ブロック１３が細紐１５の引く力を失って弾力ばね１４の作用によって右方へ移動し、位置制限台形ブロック１３が改めて位置制限溝１２の中に入り移動ブロック１１の移動を制限し、従動軸２０が止められ、操作全体が終了する。 The order of mechanical operation of the entire invention of the present application is:
1. The motor 22 is started, the motor 22 operates to drive and rotate the transmission shaft 21, whereby the slide gear 55 is driven and rotated, and the driven gear 19 connected so as to mesh with the slide gear 55 is interlocked. The driven shaft 20 and the second reel 17 and the first reel 18 on the driven shaft 20 rotate in conjunction with each other, and the second reel 17 and the first reel 18 rotate to rotate the first pull string 39 and the first reel. The two-pull string 61 is pulled, which pulls the two moving plates 35 to both front and rear sides, exposing the internal structure of the base 36, providing convenience for inspection and repair.
2. When the moving plate 35 on the front side moves until it comes into contact with the push block 42 on the front wall of the elevating space 62, the push block 42 moves forward, pulls the fine string 15 and the string 40, and the thin string 15 is pulled. Pulls the position limiting trapezoidal block 13 away from the position limiting groove 12, the moving block 11 loses the limit and can slide up and down on the fixed shaft 37, the string 40 is pulled and the slide gear 55 is pulled to the right, and the slide gear The 55 disengages from the meshing state with the driven gear 19 and meshes with the rotary gear 26, the driven shaft 20 stops rotating, and the rotary gear 26 connected so as to mesh with the slide gear 55 begins to rotate.
3. The rotary gear 26 rotates to drive and rotate the rotary shaft 24 and the third reel 29 and the fourth reel 32 at the right end of the rotary shaft 24, whereby the hemp rope 30 and the electric wire 31 slowly loosen and move blocks. When 11 and the base 36 start to slide downward on the fixed shaft 37 and the base 36 is released from the contact state with the push block 57, the push block 57 moves downward due to its own gravity and the elasticity of the telescopic spring 59. Loosen the pull string 47 of the book, the two trapezoidal blocks 44 lose the pulling force of the pull string 47 and move downward to enter the two position limiting holes 48, and the moving plate 35 returns by the action of the return spring 38. There are restrictions on what you can do.
4. When the base 36 is lowered to a position suitable for inspection and repair, the motor 22 is stopped, and when the inspection and repair are completed, the motor 22 is rotated in the reverse direction, whereby the third reel 29 and the fourth reel 32 are rotated in the reverse direction. The hemp rope 30 and the electric wire 31 are tightly pulled in, the base 36 is pulled upward again and returned, and the upper end surface of the base 36 is again in contact with the push block 57, which pulls the two drawstrings 47. The pull string 47 pulls the two trapezoidal blocks 44 upward to separate them from the position limiting hole 48, and the two moving plates 35 lose the limitation of the trapezoidal block 44 and are restored by the elasticity of the return spring 38, and the two moving plates The 35 can pull and return the first pull string 39 and the second pull string 61 in the process of returning.
5. The moving plate 35 on the front side separates from the push block 42, the push block 42 moves to the right by the action of the elastic spring 43 and returns, the thin string 15 and the string 40 loosen, and the slide gear 55 pulls the string 40. The position-restricting trapezoidal block 13 loses the pulling force of the string 15 and moves to the right by the action of the elastic spring 14, and the position-restricting trapezoidal block 13 moves to the left by the action of the contraction spring 54 and returns. The movement of the moving block 11 is restricted by entering the position limiting groove 12 again, the driven shaft 20 is stopped, and the entire operation is completed.
