Abstract
The invention discloses a method for pre-placing a skid on a portal frame in ship construction, which is based on a device comprising the following steps: the clamping head is provided with a u-shaped structure and is used for being clamped at the upper part of the portal; the bolt is in threaded connection with the chuck, and the screw can abut against the gantry; the elastic part is fixed on one side of the chuck; the method comprises the following steps: placing the two devices on the upper part of the portal frame, so that the u-shaped structure is clamped on the portal frame, and the elastic parts of the two devices are oppositely arranged; tightening a bolt so that the bolt abuts against the gantry; a skid is placed between the two devices. The invention realizes the one-time determination of the positions of the portal frame and the skid by pre-placing and fixing the skid in advance, avoids the determination of the position of the skid after the portal frame is placed stably, improves the working efficiency of constructors and ensures the safety of the constructors.
Description
Technical Field
The invention belongs to the field of segmental transportation in ship construction, and particularly relates to a method for pre-placing a skid on a portal frame in ship construction.
Background
When resting on a portal after a staged stripping, it is often necessary to place skids on the portal in order to prevent paint damage and to avoid rigid contact. Because the paddings cannot be fixed on the gantry, when the gantry is moved to the lower part of the subsection after the subsection is lifted, the paddings need to be manually placed on the gantry and the position of the paddings needs to be adjusted, so that serious potential safety hazards exist. Patent CN201720804782.3, a but portal of putting lumber skid in advance, need be with ordinary portal transformation, because the part of its increase can not be dismantled, the portal upper surface is uneven when need not to use the lumber skid, and is unable general, has certain defect.
Disclosure of Invention
The invention provides a method for pre-placing a skid on a portal frame in ship construction, aiming at the problems in the prior art, and partial embodiments of the invention can solve the problems.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for pre-laying skid on a portal in shipbuilding, the method being based on a device comprising: the clamping head is provided with a u-shaped structure and is used for being clamped at the upper part of the portal; the bolt is in threaded connection with the chuck, and the screw can abut against the gantry; the elastic part is fixed on one side of the chuck; the method comprises the following steps: placing the two devices on the upper part of the portal frame, so that the u-shaped structure is clamped on the portal frame, and the elastic parts of the two devices are oppositely arranged; tightening a bolt so that the bolt abuts against the gantry; a skid is placed between the two devices.
Preferably, the elastic part is a rubber pad.
Preferably, before the portal frame is placed at the determined position, the placing position of the skid on the portal frame is confirmed, and the device is installed on the portal frame according to the placing position of the skid.
Preferably, the skid is removed after use.
Compared with the prior art, the invention has the beneficial effects that: through putting in advance and fixed skid, realize the disposable definite of portal and skid position, avoided putting the position of confirming the skid again behind the steady portal, improved constructor's work efficiency to constructor's safety has been guaranteed.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention.
As shown in fig. 1 to 5, the present embodiment provides a chuck adapted to pre-set a skid before being lifted by a sectional crane, comprising: the device comprises a common door frame, a clamping head, a bolt, a rubber pad and a skid. The positions of the chuck and the skid can be moved along the upper surface of the portal frame, and the position of the skid can be fixed by screwing the bolt after the chuck and the skid are adjusted in place.
Compared with the existing portal frame, the portal frame has the advantages that the positions of the portal frame and the skid are determined at one time by pre-placing and fixing the skid in advance, the situation that the position of the skid is determined after the portal frame is placed stably is avoided, the working efficiency of constructors is improved, and the safety of the constructors is ensured.
Another embodiment discloses a method for pre-placing skid on a portal frame in ship construction, which is based on a device comprising: the chuck is provided with a u-shaped structure and is used for being clamped at the upper part of the portal; the bolt is in threaded connection with the chuck, and the spiral can abut against the gantry; the elastic part is fixed on one side of the chuck; the method comprises the following steps: placing the two devices on the upper part of the portal frame to enable the u-shaped structure to be clamped on the portal frame, wherein the elastic parts of the two devices are arranged oppositely; screwing the bolt to enable the bolt to abut against the portal; a skid is placed between the two devices.
The elastic part is a rubber pad.
Before the portal frame is placed at the determined position, the placing position of the skid on the portal frame is confirmed, and the device is installed on the portal frame according to the placing position of the skid.
And after the skid is used, the device is disassembled.
Although the present invention has been described in detail with respect to the above embodiments, it will be understood by those skilled in the art that modifications or improvements based on the disclosure of the present invention may be made without departing from the spirit and scope of the invention, and these modifications and improvements are within the spirit and scope of the invention.
