[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, the first embodiment of the present invention is a safety protection device for underground pipelines crossing a narrow foundation pit, comprising a supporting rope 5, a crossing frame 2, a suspension rope 7 and a suspension structure. Two crossing frames 2 are provided, and the two crossing frames 2 are fixed on both sides of the foundation pit. The two crossing frames 2 are respectively supported at both ends of the supporting rope 5, and the top end of the suspension rope 7 is connected to the supporting rope 5. The suspension structure is installed at the bottom end of the suspension rope 7, and the suspension structure is used to suspend the pipeline.

[0026] By setting up spanning frames 2 on both sides of the foundation pit, then using supporting ropes 5 to span across the two spanning frames 2, and using suspension ropes 7 and suspension structures to suspend different positions of the pipeline in the foundation pit, the effect of protecting the pipeline is achieved, avoiding disturbance of the pipeline during the foundation pit construction process, accelerating the construction progress, having good economic and social benefits, and being suitable for promotion and application in the field of construction engineering.

[0027] A positioning anchor 1 is provided at the bottom of the spanning frame 2. By positioning the anchor 1, the spanning frame 2 can be more stably erected on both sides of the foundation pit.

[0028] A ground wire pulley 3 is installed on the spanning frame 2, and the ground wire pulley 3 is supported at the bottom end of the supporting rope 5. Specifically, the ground wire pulley 3 can be replaced by a positioning wheel, and the supporting rope 5 is supported by the ground wire pulley 3. In the process of tightening the supporting rope 5, the ground wire pulley 3 can be rotated to better adapt to the tightening of the supporting rope 5.

[0029] Both ends of the supporting rope 5 are connected to the pull-wire anchors 4. By providing the pull-wire anchors 4, the two ends of the supporting rope 5 can be fixed, so that the supporting rope 5 is in a taut state and can be effectively supported by the two ground pulleys 3.

[0030] The guy wire anchor 4 and the supporting rope 5, and the suspension rope 7 and the supporting rope 5 are connected by a chain hoist 6. By operating the chain hoist 6 between the guy wire anchor 4 and the supporting rope 5, the supporting rope 5 can be tightened. By operating the chain hoist 6 between the suspension rope 7 and the supporting rope 5, the height of the suspension structure can be adjusted, and the height of the suspended pipeline can be adjusted at the same time.

[0031] The hanging structure includes a wire buckle 8 and a rope clamp 9. The rope clamp 9 is used to tighten the wire rope for bundling the pipeline, and the wire buckle 8 is used to connect the wire rope for bundling the pipeline with the hanging rope 7. Specifically, a woven bag or a sack can be wrapped around the outside of the hanging point of the pipeline, and then a template is set at the bottom of the sack for support, and then the sack and the wooden board are bundled as a whole with a wire rope, and then the hanging structure and the chain hoist 6 are used to lift the hanging structure, and then the pipeline is lifted.

[0032] like Figures 2 to 5 As shown, in the second embodiment of the suspension structure, the suspension structure includes a clamping arm 10, a rotating shaft 11 for rotatably connecting the two clamping arms 10, the bottom end of the suspension rope 7 is connected to the top end of the two suspension arms, and a clamping block 12 is provided at the bottom of the opposite sides of the two clamping arms 10.

[0033] During operation, the suspension device is lowered to the vicinity of the pipeline using the suspension rope 7, and then the two clamping arms 10 are opened, the two clamping blocks 12 are moved to both sides of the pipeline, and then the two clamping blocks 12 are manually operated to clamp the pipeline from both sides. Afterwards, the suspension device is lifted by operating the chain hoist 6, and at this time, under the self-locking effect of gravity, the suspension structure can lift the pipeline and stably clamp it.

[0034] The inner side surface of the clamp block 12 is an arc surface, and when the clamp block 12 clamps the pipeline, the lower surface of the clamp block 12 is in a state where the inner end is tilted downward. By such an arrangement, after the suspension structure clamps the pipeline on the ground, the suspension structure is directly placed on the ground. At this time, the gravity effect cooperates with the state of the lower surface of the clamp block 12, so that the gravity effect can make the suspension structure clamp the pipeline more stably and keep the suspension structure clamping the pipeline.

[0035] A rotating plate 13 is rotatably connected to the clamping arm 10 at a position above the rotating shaft 11, and a suspension shaft 14 for connecting the suspension rope 7 is rotatably connected between the top ends of the two rotating plates 13. The suspension rope 7 is lifted upward by the suspension shaft 14, and at this time, the suspension shaft 14 simultaneously pulls the top ends of the two rotating plates 13 upward, so that the bottom ends of the two rotating plates 13 swing relative to each other, and the two rotating plates 13 cause the two clamping arms 10 to rotate, so that the two clamping blocks 12 stably clamp the pipeline from both sides of the pipeline.

[0036] Furthermore, a guide plate 15 is fixedly installed at the end of the rotating shaft 11, and the end of the suspension shaft 14 is slidably set in the guide plate 15. Arc plates 16 with the rotating shaft 11 as the center are fixedly installed on both sides of the guide plate 15. A slot 17 is set on the inner surface of the arc plate 16. The top sliding sleeve of the clamping arm 10 is provided with an insert block 18, and the bottom of the insert block 18 is provided with a spring 19 whose bottom end is connected to the clamping arm 10. When the clamping block 12 clamps the pipeline, the insert block 18 is inserted into the slot 17.

[0037] Specifically, when the clamping block 12 does not clamp the pipeline, the top of the plugging block 18 abuts against the inner surface of the arc plate 16, and at this time, the spring 19 is compressed. In the process of the bottom ends of the two clamping arms 10 swinging relative to each other to clamp the pipeline, the clamping arms 10 drive the two plugging blocks 18 to move inward on the inner surface of the arc plate 16. When the clamping block 12 clamps the pipeline, the plugging block 18 is aligned with the slot 17. At this time, the plugging block 18 is automatically inserted into the slot 17 under the elastic action of the spring 19, and the slot 17 cooperates with the plugging block 18 to lock the clamping arm 10, so that in the process of hanging the pipeline, the suspension structure stably maintains the clamping state of the pipeline.

[0038] The clamping arm 10 includes an upper part and a lower part which are distributed vertically. The top of the upper part is inclined inwards. The insert block 18 is slidably mounted on the top of the upper part. The bottom end of the spring 19 is fixedly connected to the upper part.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
