Description

【考案の詳細な説明】〔産業上の利用分野〕本考案はコンクリートブロツクのような重い物
を吊上げ移動する際に使用する吊クランプの改良
に係るものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a lifting clamp used when lifting and moving heavy objects such as concrete blocks.

[Problems to be solved by conventional techniques and ideas]

従来吊クランプの挾持腕の下端挾着部には吊下
物を確固に保持する為外周面に係合歯を繞設した
係合盤を付設している。 Conventionally, a lower end clamping portion of a clamping arm of a hanging clamp is provided with an engagement plate having engagement teeth on its outer circumferential surface in order to securely hold a suspended object.

この係合盤は出願人の出願に係る実開昭61−
165986号に開示されているように、左右２個所の
係合歯の一方が摩耗したら係止盤を裏返しにする
ことにより新しい反対側を使用し、それだけ係止
盤を長期間使用している。 This engagement plate is the Utility Model Application Publication No. 61-2010 related to the applicant's application.
As disclosed in No. 165986, when one of the two left and right engaging teeth wears out, the locking plate is turned over and a new opposite side is used, allowing the locking plate to be used for a longer period of time.

本考案は、この裏返しにする厄介さを無くすと
同時に２個所ではなく４個所も使用し得るように
して係止盤の長期間使用を可能にした吊クランプ
の改良に係るものである。 The present invention relates to an improvement of a hanging clamp that eliminates the trouble of turning the clamp over, and at the same time allows the use of four locations instead of two, thereby making it possible to use the locking plate for a long period of time.

[Means for solving problems]

添付図面を参照にしてその構成を詳述すると次
の通りである。 The configuration will be described in detail with reference to the accompanying drawings as follows.

引き上げることにより左右対向状態に設けた挾
着腕１，２で重い吊下物Ａを挾着保持する吊クラ
ンプにおいて、周面に歯車歯状の係合歯３を形成
し、中心に止着軸孔４を穿設し、止着軸孔４の周
りに等しい距離で左右上下４個所に止着選択孔５
を穿設した係止盤６を挾持腕１，２の下端挾持部
１′，２′に２本の取付ボルトナツト７，８，７′，
８′と２個所の取付孔９，１０とにより係止盤６
の係合位置を４回新しい所に変更できるように固
定したことを特徴とするものである。 In a hanging clamp that clamps and holds a heavy suspended object A with clamping arms 1 and 2 provided in left and right opposing positions when pulled up, gear tooth-shaped engagement teeth 3 are formed on the circumferential surface, and a fixing shaft is provided at the center. A hole 4 is drilled, and fixing selection holes 5 are provided at four locations on the left, right, top and bottom at equal distances around the fixing shaft hole 4.
The locking plate 6 with the holes drilled therein is attached to the lower end clamping parts 1' and 2' of the clamping arms 1 and 2, and two mounting bolts and nuts 7, 8, 7',
8' and two mounting holes 9 and 10, the locking plate 6
It is characterized by being fixed so that the engagement position can be changed four times to a new position.

[Effect]

第１図の状態で使用しているうちにａ部の係合
歯が摩耗したら取付ボルトナツト７，７′をゆる
め、且つもう１本の取付ボルトナツト８，８′を
抜き、係止盤６を略90度廻動せしめ、次の止着選
択孔５と取付孔１０とを合わせ、再び取付ボルト
８を挿入し、２本の取付ボルト７，８のナツト
７′，８′を締付すると係止盤６は新しい係合歯３
で吊下物Ａを挾着することになる。 If the engaging teeth at part a wear out while being used in the condition shown in Figure 1, loosen the mounting bolts 7 and 7', and remove the other mounting bolt and nut 8 and 8', and remove the locking plate 6. Rotate 90 degrees, align the next fastening selection hole 5 with the mounting hole 10, insert the mounting bolt 8 again, and tighten the nuts 7' and 8' of the two mounting bolts 7 and 8 to lock it. The plate 6 is a new engagement tooth 3
Hanging object A will be clamped at this point.

そして再び摩耗したらまた次の位置に約90度廻
動して固定し、新しい係合歯３で挾持する。 Then, when it wears out again, it is rotated about 90 degrees to the next position, fixed, and clamped with new engagement teeth 3.

以上本考案の係合歯３はａ，ｂ，ｃ，ｄの４個
所を選択使用できる。 As described above, the engaging teeth 3 of the present invention can be selectively used at four locations a, b, c, and d.

〔Example〕

係止盤６はS45C材を使用して鋳造後焼入れす
る。 The locking plate 6 is made of S45C material and is hardened after being cast.

取付選択孔５は90度のずれ間隔で設ける。 The mounting selection holes 5 are provided at 90 degree offset intervals.

係合歯３は約90度の谷角度αを保有させ、頂部
に平面３′を形成し、外周両縁を直角に形成する。 The engaging tooth 3 has a valley angle α of about 90 degrees, has a flat surface 3' at the top, and has both outer peripheral edges formed at right angles.

[Effect of idea]

本考案は上述のように構成したから、係合歯が
摩耗したら係止盤を次の取付選択孔で止着するよ
うにすると４個所での使用が可能となり、それだ
け係止盤を長期間使用できることになる。 Since the present invention is configured as described above, if the engagement teeth wear out, the locking plate can be fixed at the next mounting selection hole, making it possible to use it in four locations, which allows the locking plate to be used for a long time. It will be possible.

その際従来品のように係止盤を裏返しにする必
要がなく、而かも取付ボルトの着脱は１本だけで
良いからその切り換えも極めて容易に行い得るこ
とになる等秀れた実用上の効果を発揮する吊クラ
ンプとなる。 At this time, unlike conventional products, there is no need to turn the locking plate upside down, and since only one mounting bolt is required to be attached and detached, switching can be done extremely easily, which has excellent practical effects. This is a hanging clamp that exhibits the following.
