Technical Field

[0001] The utility model relates to the technical field of pipeline installation equipment for pipe networks, and particularly relates to a pipe installation lifting device. Background Art

[0002] When installing outdoor trench pipes, usually due to the large pipe diameter, operators need to use methods such as padding or manual lifting for installation and welding. However, when constructing according to this method, the following problems exist:

[0003] 1. When using the methods of padding or manual lifting, when the diameter of the straight pipe is large, it is difficult to effectively control the accuracy of the lifting height.

[0004] 2. After lifting, only unreliable temporary fixation can be adopted, resulting in poor welding quality in the later stage, low primary acceptance rate, high secondary maintenance cost, and slow construction efficiency.

[0005] Therefore, in view of the above background art, there is an urgent need for a pipe installation lifting device to solve the problem of inconvenient pipe lifting when using padding or manual lifting of pipes for welding. Content of the Utility Model

The device framework is in a "冂" shape. On the opposite sides of the two vertical rods of the "冂"-shaped device framework, vertical racks are respectively installed. On the two vertical rods, protective sleeves that can slide up and down are respectively sleeved. Inside each of the two protective sleeves, a gear meshing with the corresponding rack is rotatably arranged, and on any or all of the protective sleeves, a driving mechanism for driving the rack to rotate or lock is provided. The two protective sleeves are arranged in parallel and are connected by the transmission rod. A pipe carrying mechanism is also commonly connected to the two protective sleeves. The pipe carrying mechanism hangs on one side of the protective sleeve and is used for carrying pipes.

[0009] To optimize the above technical solution, the specific measures taken further include:

[0010] Furthermore, the driving mechanism includes a drive shaft and a locking gear. The side wall of the protective sleeve has a gear-shaped slot. One side of the gear is rotatably mounted inside the protective sleeve, and the other side of the gear's central shaft extends to a connecting shaft. The connecting shaft passes through the center of the slot, and the end of the connecting shaft that passes through has a protruding rotating wing plate along the radial direction. The drive shaft is slidably sleeved on the connecting shaft, and the drive shaft has a sliding cavity inside that allows the connecting shaft and the rotating wing plate to move axially only. The locking gear is mounted on the outside of the drive shaft. The drive shaft is used to drive the locking gear to insert into or move away from the slot along the sliding cavity, and to drive the connecting shaft and the gear to rotate.

[0011] Furthermore, it also includes a lifting handle, which is installed at the end of the drive shaft away from the protective sleeve. The lifting handle is used to pull the drive shaft to slide or drive the drive shaft to rotate.

[0012] Furthermore, two rotating blades may be provided symmetrically, and a sliding cavity is correspondingly provided inside the drive shaft for the rotating blades to move axially along the drive shaft.

[0013] Furthermore, the gear is rotatably mounted inside the protective sleeve via a bearing, and the two ends of the transmission rod are respectively connected to the outer walls of the two protective sleeves.

[0014] Furthermore, both ends of the transmission rod are inserted into the interior of the protective sleeves on both sides, and the gears are rotatably mounted on them via bearings.

[0015] Furthermore, the pipe mounting mechanism includes a connecting plate and a pipe mounting lifting frame. The pipe mounting lifting frame is in the shape of a "U". The two ends of the "U"-shaped pipe mounting lifting frame are respectively mounted on the protective sleeves on both sides through the connecting plate. The pipe mounting lifting frame is used to mount the pipe.

[0016] Furthermore, the bottom center of the pipe installation lifting frame is provided with an upward-opening pipe installation arc, which is used to support the pipe.

[0017] Furthermore, the connecting plate is installed on the protective sleeve, the lower end of the connecting plate extends out of the protective sleeve and has an installation hole, and the two ends of the pipe installation lifting frame are respectively provided with through holes. The two ends of the pipe installation lifting frame are detachably connected by connecting pins passing through the corresponding through holes and installation holes.

[0019] The beneficial effects of this utility model are:

[0020] When in use, the utility model utilizes the "冂"-shaped device framework as a support. The driving mechanism drives the gear to rotate, so as to drive the two protective sleeves connected by the transmission rod and arranged in parallel to move up and down synchronously as required along the rack, thereby being able to adjust the use height of the pipeline carrying mechanism as required. And by using the pipeline carrying mechanism perpendicular to one side of the protective sleeve, the pipeline can stably pass through and be carried, waiting for subsequent installation.

The driving mechanism drives the gear to rotate, so as to drive the protective sleeve and the pipeline carrying mechanism to rise along the rack to the height required for installing the pipeline, and then the later welding operation can be carried out, thereby effectively improving the construction quality and work efficiency.

[0022] With the setting of the driving mechanism in the utility model, when it is necessary to rotate the gear to adjust the height, pull out the driving shaft, so that the clamping gear moves away along the sliding cavity and separates from the card slot. At this time, the driving shaft can be rotated as required. Under the limitation of the sliding cavity and the rotating wing plate, the driving shaft drives the connecting shaft and the gear thereon to rotate to complete the adjustment. When it is necessary to limit the protective sleeve at the adjusted height, push in the driving shaft, so that the clamping gear inserts along the sliding cavity and is clamped with the card slot. At this time, the teeth of the clamping gear are respectively clamped and limited corresponding to the tooth holes of the gear-shaped card slot, so that the gear no longer rotates, and the operation is extremely convenient and the structure is reliable.

Gears 8 meshing with the corresponding racks 5 are respectively rotatably arranged inside the two protective sleeves 6. And a driving mechanism for driving the rotation or locking of the rack 5 is provided on any one or all of the protective sleeves 6. The two protective sleeves 6 are arranged in parallel and connected by a transmission rod 4. A pipe carrying mechanism is also commonly connected to the two protective sleeves 6.

[0032] When the present utility model is in use, the "冂"-shaped device skeleton 2 is used as a support. The gear 8 is driven to rotate through the driving mechanism, so as to drive the two protective sleeves 6 connected by the transmission rod 4 and arranged in parallel to move up and down synchronously as required along the rack 5, thereby being able to adjust the use height of the pipe carrying mechanism as required. And the pipe carrying mechanism hanging on one side of the protective sleeve 6 is used to stably supply the pipe to pass through and carry, so as to wait for subsequent installation.

[0033] In this embodiment, the above-mentioned components can all be processed and designed according to the processing drawings.

[0034] As shown in the attached Figure 3As shown, in another specific embodiment based on the above, the drive mechanism includes a drive shaft 19 and a locking gear 18.
