Description

An external locking device for a spring hanger

technical field

The utility model relates to an external hanging locking device for a spring hanger, which belongs to the category of installation and adjustment of a pipe support and hanger, and is widely used in the fields of electric power and energy.

Background technique

At present, the locking of the spring hanger mainly adopts the following two methods: (1) open holes on both sides of the upper part of the cylinder and the corresponding positions of the spring pressure plate at the same time and install locking pins; (2) insert a spacer into the opening groove of the cylinder and use The strip is fixed and the locking device is removed after the pipe installation work is complete. With the extension of the service time of the pipeline, the spring pressure plate will deviate from the initial installation position. When the hanger component on the lower side of the turnbuckle screw needs to be adjusted or damaged and needs to be replaced, it is necessary to avoid adjusting the spring height again after the repair work is completed. Locked, but since the spring has deviate from the initial locking position at this time, the original locking device cannot be used for locking. The general method is to use a chain hoist and a wire rope to fix the spring, or use oxygen-acetylene flame to cut the scrap steel plate to process the block on site. Putting the spring into the opening slot greatly increases the workload of adjustment and brings adverse effects to the maintenance work of the hanger.

The technical scheme adopted by the present utility model to solve the above problems is: an external locking device for a spring hanger, which is characterized in that it includes a snap ring, a screw rod and a hanger clamp; the snap ring is provided with two pairs, and the two pairs of the snap ring The side is provided with a through hole matching the size of the screw rod, and the two pairs of snap rings are fixed on the upper and lower sides of the spring hanger through the screw rod and the locking nut; A hole, the hanger clamp is connected to the screw rod through a thread.

Further, the snap ring is an annular structure with a gap, and the snap ring is evenly arranged with four snap blocks along the circumferential direction, and the snap blocks are arranged close to the outer wall of the spring hanger.

Further, a threaded through hole matching the size of the suspender of the spring hanger is provided in the middle position of the suspender clamp, and the suspender clamp is connected with the suspender through a thread for locking the position of the suspender.

Further, there are two screw rods, the surface of which is a full threaded structure, and each screw rod is equipped with two locking nuts.

Further, the hanger clamp can be disassembled into two parts along the line connecting the circle centers of the threaded through holes on both sides, and is locked by bolts to form an integral structure.

Further, the installation process of the boom clamp takes precedence over the snap ring and the screw rod, and the boom clamp is first installed on the boom during use.

Compared with the prior art, the utility model has the following advantages and effects: the locking device has a simple structure and is easy to use, is externally hung on the spring cylinder, does not require additional focus points, fully utilizes the structural stability of the spring cylinder itself, and can Lock the spring at any height position. Due to the detachable feature of the hanger clamp, the spring can be directly locked without removing the hanger assembly, reducing the workload of hanger adjustment and construction.
