Description

Technical Field

[0001] The utility model relates to the field of mechanical devices for lifting pipes, and specifically to a vertical lifting auxiliary device for pipes in an underground confined space. Background Art

[0002] Underground sewage treatment plants involve a large number of pipe installations. During the vertical lifting of pipes, the environment of the confined space will bring inconvenience to the vertical lifting work of the pipes. The Chinese utility model patent with the authorization publication number of 219098530U discloses a vertical lifting auxiliary device for pipes in the confined space of an underground sewage treatment plant on May 30, 2023. The device after the upper plate and the lower plate are brought closer is inserted into the pipe. By lifting the hook with a lifting device, the hook will drive the upper plate to lift upward through the rotating suspension column. The support rod connected to the upper plate will rotate around the rotating column in an opening and closing manner. The support rod drives the inclined support to lift through the rotating rod and the bolt. The corner of the inclined support rotates around the rotating column of the lower plate, and the lower part of the inclined support will be lifted until the rubber pad connected to the lower part of the inclined support is attached to the pipe wall. However, in the above-mentioned lifting auxiliary device, during the use process, the rubber pad attached to the inner wall of the pipe will inevitably be worn, which will affect the subsequent vertical lifting effect of the pipe, and there is a potential risk of the pipe falling during the vertical lifting process of the pipe.

[0040] The present utility model will be further described below through specific embodiments. Embodiment

[0041] As Figures 1 to 5 shown, this embodiment provides an auxiliary device for vertically hoisting pipelines in a limited space of an underground sewage treatment plant, including a suspension plate 1 and a limiting part 2 fixedly and slidably connected to the suspension plate 1. A hoisting ring 3 is connected to the upper end surface of the suspension plate 1. A channel 11 is arranged in the suspension plate 1 for accommodating and sliding the limiting part 2. The limiting part 2 can form different protruding distances at different positions in the channel 11 of the suspension plate 1. During use, the device is placed below a vertical pipeline, and each limiting part 2 can limit the pipeline, so that pipelines with different apertures can be hoisted.

[0042] Specifically, a plurality of channels 11 are arranged in the suspension plate 1. In this embodiment, four channels 11 are arranged in the suspension plate 1, and one side opening of each channel 11 is located on the side surface of the suspension plate 1. The four channels 11 are rotationally symmetric about the vertical central axis of the suspension plate 1.

[0043] More specifically, the channel 11 is strip-shaped, and a plurality of equally spaced first through holes 12 are arranged in the part of the suspension plate 1 above the channel 11.

[0044] Correspondingly, the limiting member 2 includes a crossbar 21 sliding in the channel 11, and a limiting plate 22 fixed to the end of the crossbar 21. The limiting plate 22 is an arc-shaped plate, arranged vertically.

[0045] Since the channel 11 is in the shape of a long strip, the cross bar 21 is adapted to the channel 11 and is also arranged in the shape of a long strip. In accordance with the first through hole 12 arranged on the part of the hanging plate 1 above the channel 11, a plurality of second through holes 23 with equal spacing are arranged on the cross bar 21; the first through hole 12 can selectively correspond to the second through hole 23 up and down to form a stopper 2 with different extension distances.

[0046] More specifically, the first through hole 12 and the second through hole 23 are both threaded holes; the corresponding first through holes 12 and second through holes 23 are connected by bolts 4, thereby forming a stopper 2 at a specified position. By using the stopper 2 that can slide in the channel 11 of the hanging plate 1, it is possible to selectively match different first through holes 12 and second through holes 23 and then fix the stopper 2 on the hanging plate 1, so that each stopper plate 22 can form a pipe retaining plate of different sizes, and in the process of laying pipes in the underground sewage treatment plant, it is possible to vertically lift pipes of different apertures. Figure 1 , Figure 4 and Figure 5 They are respectively suitable for the lifting assistance of pipes with different apertures.

[0047] In order to prevent collision during vertical pipe hoisting, a first buffer pad is arranged on the upper end surface of the hanging plate 1, a second buffer pad is arranged on the side of the limit plate 22 facing the hanging plate 1, and a third buffer pad is arranged on the upper end surface of the cross bar 21. The above buffer pads are made of rubber layers and fixed by bonding.

[0048] In order to facilitate the smooth lifting of the device after the pipeline is placed vertically, a third through hole 24 is opened on the limiting plate 22. When the pipeline is vertically hoisted, the lifting ring 3 of the lifting plate 1 is tied with a lifting rope, and the third through hole 24 of the limiting plate 22 is also tied with a lifting rope for auxiliary purpose. When the pipeline is hoisted to the specified position, the pipeline is positioned, and then the lifting rope of the lifting ring 3 is loosened, and at the same time, the lifting ropes of some third through holes 24 are loosened, and only one or two adjacent third through holes 24 are retained to maintain the binding state. At this time, the device is detached from the pipeline, and its lifting plate is suspended in a vertical direction, and then lifted upward, the device can be lifted up to prepare for the next pipeline hoisting process.

[0049] Before using the vertical lifting assistance device for pipelines in the confined space of the underground sewage treatment plant provided in this embodiment, first adjust the position of each limiting member 1 to an appropriate extended position according to the aperture of the pipeline diameter, and fix each limiting member 2 to the hanging plate 1 with bolts 4. Then place this device at the bottom of the pipeline, thread a lifting rope into the pipeline and tie it to the hanging ring 3 of the hanging plate 1; subsequently, also tie a lifting rope to the third through hole 24 on the limiting member 1. After vertically lifting the pipeline to the designated position in the underground sewage treatment plant, fix the pipeline in a manner suitable for the working conditions at that time. Then loosen the lifting rope of the hanging ring 3 and at the same time loosen the lifting ropes of some of the third through holes 24, only retaining the lifting ropes of one or two adjacent third through holes 24 in the tied state. At this time, this device is separated from the pipeline, and its hanging plate is hanging vertically. Then lift it upward, and this device can be lifted up to prepare for the lifting process of the next pipeline.

[0050] The vertical lifting assistance device for pipelines provided in this embodiment can be applied to the vertical lifting of pipelines under the confined space conditions of the underground sewage treatment plant. It can not only be suitable for the lifting of pipelines with different apertures, but also, because it is set at the bottom of the pipeline, it can support the pipeline during the lifting process and there is no potential risk of the pipeline falling off due to the pipeline detaching from this device. For each buffer pad in this device, even if it wears out, the pipeline will not detach from this device, and there will be no risk of the pipeline falling due to the wear of the buffer pad. Embodiment

[0051] The difference from Embodiment 1 is that, as Figures 6 - 7 shown, the channel 11 of the hanging plate 1 is in the shape of wider inside and narrower outside; in this embodiment, this channel 11 is in the shape of a knife handle. Correspondingly, a baffle 25 is fixedly connected to one end of the cross bar 21 of the limiting member 2 facing the center of the hanging plate to prevent the limiting member 2 from detaching from the hanging plate 1.

[0052] Before using the vertical lifting assistance device for pipelines in the confined space of the underground sewage treatment plant provided in this embodiment, the position of each limiting member 2 can be fixed to the hanging plate with bolts, or the bolts can be omitted. When the bolts are omitted, since a baffle 25 is provided at the inner end of the cross bar 21, the cross bar 21 will not detach from the hanging plate, and pipelines within a certain aperture range can be lifted using this device. The upper limit of the so-called certain aperture range refers to the aperture corresponding to when the limiting member 2 is stretched out to the maximum distance.

[0053] When the vertical lifting auxiliary device for pipelines in the confined space of the underground sewage treatment plant provided in this embodiment is in use, place this device at the bottom of the pipeline, thread a lifting rope through the pipeline and tie it to the hanging ring 3 of the hanging tray 1; subsequently, also tie a lifting rope to the third through-hole 24 on the limiting member 1. After vertically hoisting the pipeline to the designated position in the underground sewage treatment plant, fix the pipeline in a manner suitable for the working conditions at that time. Then, loosen the lifting rope of the hanging ring 3 and at the same time loosen the lifting ropes of some of the third through-holes 24, and only retain the lifting rope of one or two adjacent third through-holes 24 in the tied state. At this time, this device is detached from the pipeline, and its hanging tray is suspended in the vertical direction. Then, hoist it upward, and this device can be lifted up to prepare for the hoisting process of the next pipeline.
