Description

Technical Field

[0001] The utility model relates to the technical field of safety ropes, in particular to an oxidation ditch safety rope hanging device. Background Art

[0002] The oxidation ditch is a variation of the activated sludge process. Its aeration tank is a closed ditch type, so it is different from the traditional activated sludge process in hydraulic flow. It is a circulating flow aeration ditch connected end to end, and sewage infiltrates into it to be purified. The earliest oxidation ditch was not made of reinforced concrete, but an earth ditch with slope protection, which was intermittently watered and aerated.

[0003] Sludge and debris often accumulate on the inside of the oxidation pond, which requires manual cleaning. When workers perform cleaning operations in the pond, they often wear safety ropes for protection. One end of the safety rope is locked on the guardrail next to the oxidation pond through a buckle. However, since common guardrails have cross-supported rods, the buckle of the conventional safety rope cannot directly cross the cross guardrails. When the workers change the cleaning position, they need to remove the safety rope buckle, move it and then buckle it again, which is inconvenient to operate and affects the cleaning efficiency.

[0004] Therefore, a safety rope suspension device for an oxidation ditch which is easy to move and has a stable connection is needed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] See also Figure 1-5 As shown, the utility model provides the following technical solutions: an oxidation ditch safety rope hanging device comprises a connecting railing 1, on which a supporting railing 2 is fixed;

[0026] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5Specifically, the outer side of the connecting railing 1 is movably sleeved with a lock assembly 3, and the lock assembly 3 includes a supporting arc rod 31 and a connecting arc rod 32, both of which are arc-shaped and connected at both ends. The supporting arc rod 31 is sleeved on the outer side of the connecting railing 1, and a rotation groove 311 is opened on the inner side of one end of the supporting arc rod 31, and a connecting hole 312 is opened at one end of the rotating groove 311. A docking groove 313 is opened at the other end of the supporting arc rod 31, and a rotating rod 321 is fixedly provided at one end of the connecting arc rod 32, and the rotating rod 321 is inserted into the inner side of the rotating groove 311, and the rotating rod 321 passes through the connecting hole 312. A limiting ring 322 is fixedly provided on the outer side of one end of the rotating rod 321, and the limiting ring 322 is located on the inner side of the rotating groove 311. The rotation rod 321 can be stably limited, and a fixing spring 323 is fixed on one side wall of the limiting ring 322. The fixing spring 323 is sleeved on the outer side of the rotation rod 321, and one end of the fixing spring 323 is fixed to the inner wall of the rotation groove 311. Because it is fixed, when the rotation rod 321 drives the other end of the fixing spring 323 to rotate, the spring follows the rotation to generate a rebound force, which can reset the docking plate 324 to the inner side of the docking groove 313 after moving. The other end of the connecting arc rod 32 is fixedly provided with a docking plate 324, and the docking plate 324 is movably engaged with the inner side of the docking groove 313. A safety rope 4 is connected to the outer side of the supporting arc rod 31; a tying arc rod 33 is fixedly provided on the outer wall of the supporting arc rod 31, and reference is made to the attached drawing. Figure 5 One end of the safety rope 4 is connected to the tying arc rod 33; one end of the tying arc rod 33 is provided with a rope buckle 41, and the rope buckle 41 is sleeved on the outside of the tying arc rod 33; the width of the connecting arc rod 32 is greater than the rod diameter of the supporting railing 2, which is convenient for installing the lock buckle. In this scheme, the lock buckle is installed on the connecting railing 1, and the connecting safety rope 4 is used for staff to clean the pool. When the staff moves, the safety rope 4 moves. When the lock buckle moves to the intersection of the railing, the staff can swing the safety rope 4 to drive the connecting arc rod 32 to hit the railing, so that it rotates and passes over the connecting arc rod 32, and then resets under the action of the fixed spring 323, so that the lock buckle can easily pass over the intersection of the railing and the connection is stable at the same time, which is convenient for the movement operation of the safety rope 4 and the cleaning work.

[0027] Reference Figure 5 As shown, specifically, magnetic slots 314 are symmetrically provided on the inner walls on both sides of the docking slot 313, and magnetic blocks 325 are fixedly provided on the two side walls of the docking plate 324. The magnetic blocks 325 are magnetically engaged with the inner side of the magnetic slots 314. This solution uses magnetic engagement to enable one end of the connecting arc rod 32 to be stably engaged with one end of the supporting arc rod 31 to avoid easy falling off and causing unstable connection between the lock and the railing, thereby having high safety.

[0028] Reference Figure 5As shown, specifically, the inner wall of the docking groove 313 is arc-shaped, the outer wall of the docking plate 324 is arc-shaped, and the inner size of the docking groove 313 is adapted to the size of the docking plate 324; this solution uses the arc-shaped docking groove 313 and the arc-shaped docking plate 324 to enable the docking plate 324 to be easily moved left and right on the inner side of the docking groove 313, thereby facilitating the opening and closing of the installation lock.

[0029] Reference Figure 1 As shown, specifically, the length of the supporting arc rod 31 is greater than the length of the connecting arc rod 32; after the lock buckle is sleeved on the outside of the railing, when the safety rope 4 is pulled, the supporting arc rod 31 can always be sleeved on the outside of the railing, avoiding the situation where the connection between the supporting arc rod 31 and the connecting arc rod 32 is easily unstable when the connection is subjected to force.

[0030] The working principle and use process of the utility model are as follows: when the staff is cleaning the oxidation ditch of the sewage treatment, the staff rotates the connecting arc rod 32 of the lock buckle, and then sets the supporting arc rod 31 to the outside of the connecting railing 1, and the safety rope 4 on the supporting arc rod 31 is used for the staff to work safely. As the staff moves, the safety rope 4 is driven to move. When the lock buckle of the safety rope 4 moves to the intersection of the supporting railing 2 and the connecting railing 1 and cannot move, the staff can lift the safety rope 4 for a section, so that the lock buckle at one end of the safety rope 4 naturally droops, so that the connecting arc rod 32 is located on one side of the supporting railing 2. The staff swings the safety rope 4 so that the connecting arc rod 32 hits the supporting railing 2, so that the connecting arc rod 32 rotates and passes over the supporting railing 2, so that the safety rope 4 can move smoothly, which is convenient for cleaning.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
