本考案は、タワークレーンにおけるクレーンの
クライミング装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a crane climbing device in a tower crane.
［従来技術］

ミングさせる仕方とが一般に行われている。[Prior Art] In order to climb a crane by using a tower that is erected along the wall of a structure and supported by appropriate support members, conventionally, a rack member is attached to one side of the tower and a mount on which the crane is placed and fixed is used. One method is to engage the pinion gear installed on the rack with the easy member and allow the crane to climb along the side of the tower.The other is to keep the pedestal on which the crane is placed and fixed fixedly fixed to the steel cross beam of the tower at all times. The common practice is to cut the connection between the tower and the steel cross beams and allow the crane to climb through the tower.
前者は、クレーンのクライミングが容易である
反面機構が複雑なものとなり、かつ荷重がタワー
の片側に集中し、大きな転倒モーメントを生じる
欠点がある。これに対して、後者は、機構的に簡
単であり、かつ前者のようにタワーに大きな転倒
モーメントが生じない利点があるが、クレーンの
クライミングに手間取る欠点がある。 Although the former method allows the crane to easily climb, it requires a complicated mechanism and has the disadvantage that the load is concentrated on one side of the tower, resulting in a large overturning moment. On the other hand, the latter has the advantage that it is mechanically simple and does not generate a large overturning moment on the tower unlike the former, but has the disadvantage that it takes time to climb the crane.
すなわち従来のひとつの形式は、架台ビームの

であり、かつ危険を伴うものである。 In other words, one conventional method is to install a foldable support arm at the tip of the trestle beam, and always fix the support arm to the steel cross beam side of the tower, and when climbing the crane, move the support arm to the trestle side. The support arm is of a foldable type and has considerable weight, and the work of extending it to the steel cross beam side of the tower and folding it to the pedestal side is troublesome and dangerous.

公報参照）。 Another type is the one proposed by the applicant, in which a connecting member (outrigger) corresponding to the support arm of the above type is provided on the pedestal so that the drawer can be pulled out freely, and when the pedestal is fixed to the steel cross beam of the tower. The connecting member is pulled out to the steel cross beam side of the tower, and the connecting member and the steel cross beam, and the connecting piece and the pedestal are fixed by tightening bolts. When climbing the crane, the bolts are removed and the connecting member is pulled out to the trestle side. (Refer to Utility Model Publication No. 54-44352).

い、かつ多人数を必要とした。 With this type, all you have to do is slide it on the pedestal when pulling out and retracting the connecting member.
It has the advantage of being easier to work with compared to the above-mentioned folding type, but since the connecting member was previously pulled out manually, there was a risk of getting your hands caught in the pullout operation, and there were many problems with fixing. Because this was done using high-tension bolts, it was necessary to insert the core into the hole at the point where it protruded from the beam on the building side and tighten the bolt firmly, which was quite dangerous and required a large number of people.

うに引出側に油圧が印加されている。[Means for Solving the Problems] According to the present invention, a connecting member that can be slid and retracted is provided on a pedestal on which a crane is placed and fixed, and the connecting member is normally pulled out to the side of the steel frame cross beam of the tower to connect the connecting member and the steel frame. In a crane climbing device for a tower crane, in which the horizontal beam is fixed by a fixing means, and when the crane is to be climbed, the connection member and the steel cross beam are disconnected and the connecting member is retracted to the frame side. A hydraulic cylinder for pulling out and retracting the connecting member is provided between the gantry beam and the connecting member, a fixing pin is provided for connecting the gantry beam and the connecting member in the pulled out state, and the hydraulic cylinder is not pulled out. In this state, hydraulic pressure is applied to the drawer side so that the movement of the connecting member relative to the frame beam is prevented by the hydraulic pressure of the hydraulic cylinder.

For safety, the pedestal beam is fixed by a fixing pin, and pressure oil prevents relative movement between the connecting member and the pedestal beam.
そしてクライミングさせるときには、固定手段
および固定ピンを外して油圧シリンダを引込めて
別のクライミング手段により上昇させればよい。 When climbing, the fixing means and fixing pin can be removed, the hydraulic cylinder can be retracted, and another climbing means can be used to raise the device.

ことができる。 As described above, according to the present invention, when the connecting member is pulled out, the movement of the connecting member relative to the frame is prevented by the hydraulic pressure of the hydraulic cylinder. Safety and workability can be significantly improved without requiring the work of exposing the core and tightly tightening a large number of bolts.

The frame is generally designated by 4 and is roughly composed of two frame beams 5, a cross member 6 that connects the frame beams 5, a reinforcing member 7, and the like. Then, the mast 1 is mounted on this frame 4 by the Kanzashi 8 and Kanzashi bolt 9.
0 is mounted and fixed, and a revolving body and a crane main body (not shown) are attached to the top of the mast 10. Reference numeral 11 denotes a connecting member (outrigger) provided at each tip of the pedestal beam 5 so that the drawer can be freely drawn out and retracted by sliding. Reference numeral 12 denotes a hydraulic cylinder provided between the frame beam 5 and the connecting member 11, and the connecting member 11 is pulled out and retracted by the hydraulic cylinder 12 constituting this hydraulic jack.

Kanzashi Bolt 14
Fix it by. When the connecting member 11 is pulled out, the hydraulic pressure of the hydraulic cylinder 12 acts on the connecting member 11 in the drawing direction, so the movement of the connecting member 11 with respect to the frame beam 5 is prevented, and the connecting member 11 is moved as in the conventional case. In order to fix the frame 4 to the pedestal beam 5, it is not necessary to center the hole and tighten and fix it with a large number of bolts. 3 may be fixed with a small number of bolts 14. Since the connecting member 11 is pulled out using a hydraulic jack, that is, a hydraulic cylinder 12, there is no risk of getting your hands caught in the pulling operation, unlike in the case of a manual pull-out type. For safety, the fixing pin 15 is inserted between the connecting member 11 and the frame beam 5 when the connecting member 11 is pulled out.

Then, the fixing pin 15 inserted between the connecting member 11 and the pedestal beam 5 is removed, and the connecting member 11 is retracted to the pedestal 4 side by the hydraulic cylinder 12. At that time,
The pedestal 4 is held by a hydraulic cylinder (not shown) or a lifting device (also not shown) mounted on a tower.

When the pedestal 4 is pushed up (pulled up) to a predetermined height, the connecting member 11 is pulled out and fixed in the manner described above. After that, repeat this operation to climb the crane. Also, using such a beam, it is possible to climb using other types of lifting devices such as lifts and elevators.
