Description

Technical Field

[0001] This utility model relates to the field of underground construction equipment, specifically to an in-situ suspension protection device for underground pipelines. Background Technology

[0002] Subway construction is a top priority in urban rail transit development, with the vast majority of subway stations being underground. Subway stations often contain underground pipelines. Given the depth and wide span of subway stations, these pipelines are subject to significant bending moments during construction, potentially causing damage that could disrupt residents' lives and hinder construction. Therefore, protecting underground pipelines is an unavoidable challenge during subway station construction. Current construction methods involve relocating these pipelines outside the station structure before commencing construction.

[0003] However, when dealing with large-diameter, long-span underground pipelines such as urban water supply pipelines and power lines, the relocation of such underground pipelines is subject to problems such as long construction periods, numerous connection procedures and complicated formalities for water and power outages, and high investment costs. At the same time, the pipeline relocation construction process requires the temporary occupation of municipal roads, which also has a significant impact on traffic.

[0004] Existing technologies often protect underground pipelines by installing pipeline suspension protection devices. For example, utility model patent CN221196383U discloses an underground pipeline suspension protection device, including a suspension beam and several suspension mechanisms. The suspension beam is erected on the top of both sides of the station pit. Each suspension mechanism includes a hanging plate, a pull plate, and a support plate. The hanging plate is connected to the suspension beam, and pull plates are fixedly connected to both ends of the hanging plate. A support plate is fixedly connected between the ends of the two pull plates away from the hanging plate. However, this solution is difficult to adapt to pipelines of different diameters, and there may be ground subsidence around the pit during construction. This solution also makes it difficult to adjust the suspension height according to the construction conditions. Utility Model Content

[0029] like Figures 1-2 As shown in the preferred embodiment of this utility model, an in-situ suspension protection device for underground pipelines includes a suspension beam 100 and a hoisting assembly, with the hoisting assembly located at the bottom of the suspension beam 100; the suspension beam 100 is a Bailey beam.

[0030] The hoisting assembly includes a lifting mechanism and a support frame 200, wherein the support frame 200 is connected to the lifting mechanism;

[0031] The support frame 200 includes a U-shaped support mother frame and a U-shaped support sub-frame. One end of the support mother frame is a first support frame 210, and the other end is a second support frame 220. The first support frame 210 and the second support frame 220 are provided with sliding grooves. The two ends of the support sub-frame are respectively inserted into the sliding grooves of the first support frame 210 and the second support frame 220. The first support frame 210 and the second support frame 220 form a rectangular support frame 200. The underground pipeline 300 passes through the support frame 200 and is suspended by the support frame 200 and the lifting mechanism.

[0032] One end of the support subframe is an adjustment frame 230, and the other end is an insertion frame 240; the adjustment frame 230 is provided with a plurality of adjustment holes; the adjustment frame 230 is inserted into the slide groove of the first support frame 210, and the insertion frame 240 is inserted into the slide groove of the second support frame 220.

[0033] The support frame 200 also includes fixing bolts 250. The first support frame 210 is provided with fixing holes. The fixing bolts 250 pass through the fixing holes and the adjusting holes on the adjusting frame 230 to fix the support frame 200 to the lifting mechanism. The overall width of the support frame 200 can be adjusted by adjusting the length of the support sub-frame inserted into the support mother frame to accommodate underground pipelines 300 of different diameters.

[0034] The lifting mechanism includes two sets of lead screw adjustment assemblies 400 and a support beam 410; each end of the support beam 410 is provided with a connecting rod, and the two sets of lead screw adjustment assemblies 400 are respectively connected to the connecting rod at one end.

[0035] The support beam 410 is also provided with threaded holes. The fixing bolts 250 pass through the fixing holes on the first support frame 210, the adjusting holes on the adjusting frame 230, and the threaded holes on the support beam 410 to fix the support frame 200 to the support beam 410. The support frame 200 is fixed to the support beam 410, and the lead screw adjusting assemblies 400 at both ends of the support beam 410 drive the support frame 200 to rise or fall, so as to adapt to different pit heights.

[0036] The lead screw adjustment assembly 400 includes a lead screw 430, a slider, and a connecting rod; the slider includes a first slider 440 and a second slider 450, the first slider 440 and the second slider 450 are respectively disposed on both sides of the lead screw 430, and the threads on both sides of the lead screw 430 are in opposite directions; a rotating handle 480 is provided at both ends of the lead screw 430.

[0037] The connecting rod includes a first connecting rod 460 and a second connecting rod 470. One end of the first connecting rod 460 is hinged to the first slider 440, and the other end is hinged to the connecting rod on the support beam 410. One end of the second connecting rod 470 is hinged to the second slider 450, and the other end is hinged to the connecting rod on the support beam 410.

[0038] The lifting mechanism also includes two fixed plates 420, which are connected to the bottom of the suspension beam 100. The two ends of the lead screw 430 pass through the fixed plates 420 respectively, and the two sets of lead screw adjustment assemblies 400 suspend the support frame 200 at the bottom of the suspension beam 100.

[0039] In actual use, the main support frame and the sub-support frame are fitted onto the underground pipeline 300, and the length of the sub-support frame extending into the main support frame is adjusted according to the diameter of the underground pipeline 300. After adjusting to the appropriate length, the support frame 200 is fixed to the support beam 410 by passing the fixing bolts 250 through the fixing holes on the first support frame 210 and the adjusting holes on the adjusting frame 230. The rotary handle 480 is adjusted according to the actual working conditions to drive the lead screw 430 to rotate. Since the threads on both sides of the lead screw 430 rotate in opposite directions, the sliders on both sides will move inward or outward simultaneously with the clockwise or counterclockwise rotation of the lead screw 430. When the sliders on both sides move inward simultaneously, the connecting rod drives the support beam 410 to rise; when the sliders on both sides move outward simultaneously, the connecting rod drives the support beam 410 to fall, thus achieving height adjustment.

[0040] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
