Description

Technical Field

[0001] The utility model belongs to the technical field related to cable trays, and particularly relates to a hanger structure for a hot-dip galvanized steel cable tray. Background Art

[0002] The hanger of a cable tray is a mechanical component. The bracket hanger is the main component for supporting the cable tray and cables, and it consists of a column, a column base, a bracket arm, etc. The cable tray has electro-galvanization, hot-dip galvanization, painting, plastic spraying, etc., and the surface treatment of the bracket arm part also has four types: electro-galvanization, hot-dip galvanization, painting, and plastic spraying. The hanger is used to suspend the cable tray for installation, but the related hanger structure still has the following drawbacks in actual use:

[0003] For a conventional hanger structure, most are connected by two vertical arms and one horizontal arm to form a U-shaped structure. The top of the vertical arm is fixed to the wall top, and the cable tray is fixed on the horizontal arm to complete the installation. This method completely relies on the vertical arm for force, and the force is also completely borne by the connection point between the vertical arm and the wall top. At most, a few diagonal braces are added to the vertical arm, but essentially, the force on the horizontal arm is not shared, and the force is still too concentrated, which is easy to be damaged, or the horizontal arm is bent due to other factors.

[0004] Secondly, there is no positioning structure for the cable tray on a conventional hanger. At most, a pressing plate is set on the cable tray to be connected with the horizontal arm to press the cable tray cover. However, based on this type of structure, the cable tray cannot be limited in the horizontal direction, and it cannot be effectively used for cable trays of different sizes. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hanger structure for a hot-dip galvanized steel cable tray. By setting a cross beam, vertical arms, horizontal arms, diagonal brace one, diagonal brace two, screw one, screw two, I-shaped slider, vertical rod, and pressing screw, the problems of overly concentrated force distribution on the horizontal support in the hanger, inability to share the force, easy damage, and lack of horizontal direction limiting function for the cable tray on the hanger are solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a hanger structure for a hot-dip galvanized steel cable tray, which includes two cross beams, vertical arms, horizontal arms, diagonal brace one, and diagonal brace two. The two cross beams are arranged side by side. A vertical arm is movably arranged under each cross beam. A horizontal arm is arranged at the lower part between two adjacent vertical arms. Shaft rods are fixed at both ends of the horizontal arm. The mutually remote ends of the two shaft rods are respectively fixed to the two vertical arms. Diagonal brace one and diagonal brace two are rotatably sleeved outside the two shaft rods, and diagonal brace one is closer to the horizontal arm, while diagonal brace two is closer to the vertical arm.

[0008] A chute is vertically penetrated and opened in the horizontal support arm, and two symmetrically distributed I-shaped sliders are slidably arranged in the chute. A vertical rod and a pressing screw are fixed to the upper end of each I-shaped slider, and the vertical rod is closer to the center of the horizontal support arm than the pressing screw. A pressing plate is sleeved outside the vertical rods and the pressing screws on the two I-shaped sliders.

[0009] Further, the cross beam has a T-shaped structure. A clamping groove is opened in the lower part of the cross beam and penetrates through the bottom end of the cross beam. A plugging ear is fixed to the upper end of the vertical support arm and extends into the clamping groove. A round hole is also penetrated and opened in the lower part of the cross beam. A stud is inserted through the round hole and the plugging ear and fixed by screwing a nut.

[0010] Further, a first through hole and a second through hole are penetrated and opened in the cross beam, and the first through hole and the second through hole are symmetrically distributed with the round hole as the center. A first screw is inserted through the first through holes on the two cross beams on the same axis, and nuts are screwed on both ends of the first screw extending out of the two cross beams. A second screw is inserted through the second through holes on the two cross beams on the same axis, and nuts are screwed on both ends of the second screw extending out of the two cross beams.

[0011] Further, a first ear plate is fixed to the upper end of each of the two first diagonal braces, and the first ear plate is sleeved on the first screw between the two cross beams. A second ear plate is fixed to the upper end of each of the two second diagonal braces, and the second ear plate is sleeved on the second screw between the two cross beams.

[0012] Further, a through groove is opened in the pressing plate. The vertical rod and the pressing screw pass through the through groove, and a nut is screwed on the pressing screw above the pressing plate.

[0013] Further, the upper part of the I-shaped slider is located above the horizontal support arm, the lower part of the I-shaped slider is located below the horizontal support arm, and the middle part of the I-shaped slider is located in the chute.

[0014] Further, a hot-dip galvanized steel bridge is arranged between the pressing plate and the horizontal support arm, and the vertical rods on the two I-shaped sliders are respectively in contact with the two side surfaces of the hot-dip galvanized steel bridge.

[0015] The utility model has the following beneficial effects:

[0016] The utility model solves the problems that the horizontal support in the hanger has too concentrated force distribution, cannot share the force, and is easy to be damaged by setting a cross beam, vertical support arms, horizontal support arms, diagonal braces I, diagonal braces II, screw I, and screw II; the horizontal support arm is connected between two vertical support arms through a shaft rod, and the vertical support arms are connected to the cross beam. A large number of holes are opened on the cross beam, and the cross beam is connected to the wall top through fasteners such as anchor nails and expansion screws. A large number of new force application points make the subsequent installation of the cable tray more stable. Secondly, diagonal braces I and diagonal braces II are added to share the force of the horizontal support arm, increase the force application points, and are connected to the corresponding screw I and screw II to avoid too concentrated force application points, thereby reducing damage.

[0017] The utility model solves the problem that the hanger lacks the function of limiting the cable tray in the horizontal direction by setting I-shaped sliders, horizontal support arms, vertical rods, and pressing screws; move the two I-shaped sliders closer to each other to contact the side wall of the cable tray on the horizontal support arm, and then press the pressing plate on the outside of the vertical rod and the pressing screw, so as to cover the cover plate of the cable tray. Then screw the nut onto the pressing screw and tighten it to relatively fix the pressing plate and the horizontal support arm, realizing the dual limiting use in the horizontal and vertical directions and adapting to cable trays of different sizes.
