Abstract
The utility model discloses a ladder rack locking element which comprises a bent plate. Two side faces of the plate are respectively provided with an inclined long round hole, and the long round holes in the two side faces are of a splayed structure symmetric with the bending line of the plate. The long round holes in the two sides of the ladder rack locking element can be matched with holes of an upright column or a support in a crossed mode when the upright column or the support is fixed. Enough adjusting allowance can be guaranteed and requirements of construction and installation are met. Meanwhile, after installation, when a ladder rack bears downward force, the ladder rack locking element slides downward due to vibration, so that the ladder rack locking element is tighter and tighter, the problem that fixing bolts are loosened due to severe vibration is avoided, and reliability and safety of a bridge rack are improved.
Description
Technical field
The utility model belongs to field of machining, especially relates to a kind of ladder lock firmware.
Background technique
The effect of ladder lock firmware is the device of fixed support or column, and himself necessity will have good intensity, guarantee protection himself can bearing support, column and the cable testing bridge that carries thereof with and the ability of the relevant apparatus such as cable run.
Traditional ladder lock firmware, the attachment hole on it mostly is circular hole or the criss-crossing hole being stamped to form.Though circular hole can guarantee the reliability of support or column and fix, installation precision requires too high, and common engineering project is subject to the perpendicularity of ladder lock firmware welding, and the restriction of the factors such as spacing is difficult to assurance and support or column hole supporting.In order to adapt to the needs of project installation, just change the attachment hole of ladder lock firmware into criss-crossing hole, though this perforate mode can assurance and support or column supporting fixing, but while placing the various device strenuous vibrations such as cable testing bridge in installation process,, there is certain installation hidden danger in the situation that can cause fixing bolt to slide.
Model utility content
The purpose of this utility model is to provide a kind of ladder lock firmware, when meeting construction needs, solves because strenuous vibration causes the loosening problem of fixing bolt.
For realizing the problems referred to above, the technical solution adopted in the utility model is: ladder lock firmware, the sheet material that comprises bending, is respectively equipped with the slotted hole of inclination on two sides of this sheet material, the slotted hole on two sides is symmetrical splayed shape structure along the bending line of sheet material.
Further, the angle of two of described bending sheets sides is right angle.
Further, the slotted hole on each side of described sheet material is two slotted holes that center line is parallel.
Further, described sheet material is provided with peep hole, on the bending line that is centered close to sheet material of this peep hole.
Slotted hole on two faces of ladder lock firmware, with column or support fixedly time, can intersect and coordinate with the hole of column or support, both can guarantee that it has enough adjusting surpluses, has met the needs of construction and installation, simultaneously after installation, when ladder is subject to downward power, this structure is given a shock down sliding, thereby more and more fastening, avoided becoming flexible problem because strenuous vibration causes fixing bolt, improved crane span structure reliability and Security.
Accompanying drawing explanation
Fig. 1, ladder lock firmware structural representation;
Fig. 2, ladder lock firmware mounting structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As shown in Figure 1, of the present utility model, comprise the rectangular sheet material 1 of bending, on two sides of this sheet material 1, be respectively equipped with two slotted holes 2 of inclination, the center line of the upper slotted hole of each face is parallel to each other, and the slotted hole 2 on two sides is symmetrical splayed shape structure along the bending line 3 of sheet material.
For the ease of constructing and carrying, on sheet material 1, be provided with peep hole 4, on the bending line that is centered close to sheet material 13 of this peep hole 4.At ordinary times, peep hole 4 can be used for wearing in packaging process steel wire bundle.When ladder lock firmware and column 5 or stull installation, by peep hole 4, the level state of column 5 or stull is observed, is proofreaied and correct.
As shown in Figure 2, for fixedly assembly structure schematic diagram ladder lock firmware and column 5, in installation process, ladder lock firmware is first welded and fixed with steel construction piece, then column 5 again with ladder lock firmware hole aligning, finally with bolt, fix, get final product installation.
Ladder lock firmware of the present utility model is with column or stull fixedly time, and the slotted hole 2 of inclination can intersect and coordinate with the hole of column or stull, has increased enough adjusting surpluses.After fixedly mounting with column, when ladder is subject to downward power, this structure can be more and more fastening, can not become flexible, in ocean engineering project, the installation environment of crane span structure is in long-term motion state especially, crane span structure system is when rocking up and down, between ladder lock firmware and column along with rocking, can accomplish that one is stressed, bolt is without space slidably.The ladder lock firmware of this programme can be avoided to greatest extent at vibrations in the situation thats ladder lock firmware and the loosening phenomenon of column or stull immovable point bolt, thereby guarantees the safe and stable operation of whole cable run.
Claims (5)
1. a ladder lock firmware, is characterized in that, comprises the sheet material of bending, is respectively equipped with the slotted hole of inclination on two sides of this sheet material, and the slotted hole on two sides is symmetrical splayed shape structure along the bending line of sheet material.
2. according to ladder lock firmware claimed in claim 1, it is characterized in that, the angle of two sides of described bending sheets is right angle.
3. according to the ladder lock firmware described in claim 1 or 2, it is characterized in that, the slotted hole on each side of described sheet material is two slotted holes that center line is parallel.
