Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a pipe hoisting device. Background Technology

[0002] As is well known, in recent years, with the progress of urbanization in China, large-scale buildings have been increasingly used, and pipeline systems are an important component of these buildings. In existing technologies, for large-diameter pipes, such as HVAC pipeline networks, prefabricated pipe sections are generally used, which are hoisted to the installation site and spliced ​​to obtain the corresponding pipeline. During operation, lifting equipment is usually used to suspend the pipes.

[0003] After the pipeline is suspended, the lifting device supports the pipeline. For example, in the pipeline lifting device disclosed in CN210029809U, the pipeline is suspended by fastening straps. If the pipeline is slightly tilted at this time, the staff needs to adjust the position of the lifting device. At this time, the lifting device supports the pipeline and cannot be moved directly. The pipeline needs to be lowered and the position of the lifting device adjusted, which seriously affects the work efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pipe hoisting device that facilitates the adjustment of the hoisting position and improves work efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pipe hoisting device, comprising a hoisting tool for installing a pipe, the hoisting tool comprising a support frame and a connecting frame disposed on the top of the support frame, wherein several rollers that can contact the outer wall of the pipe are rotatably connected to the support frame, the support frame slides more smoothly along the pipe axis, and several set screws for fixing the pipe are provided on the support frame.

[0006] Furthermore, several of the aforementioned top screws and support brackets are connected by threads.

[0007] Furthermore, the support frame is provided with a fixing plate, and several additional set screws are threadedly connected to the fixing plate.

[0008] Furthermore, each of the set screws has a top block installed at one end near the pipe, and a screwing block is provided at the other end of each set screw.

[0009] Furthermore, the end face of the top block is curved, flat, or inclined.

[0010] Furthermore, the support frame and the connecting frame are hinged together by a connecting shaft.

[0011] Furthermore, a lifting ring is provided at the top of the connecting frame.

[0012] Compared with the prior art, the present invention provides a pipe hoisting device, which has the following beneficial effects:

[0013] This type of pipe hoisting device uses a set screw to fix the pipe in place when it is normally suspended. When the position of the hoist is adjusted, the set screw is loosened and the hoist is moved along the pipe axis. Due to the rollers, the hoist can slide more smoothly, making it easier to adjust the position of the hoist. The pipe does not need to be lowered during the adjustment process, thus effectively improving work efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5This utility model discloses a pipe hoisting device, including a hoist for installing a pipe 10. The hoist includes a support frame 1 and a connecting frame 2 set on the top of the support frame 1. Several rollers 5 are rotatably connected to the support frame 1 and can contact the outer wall of the pipe 10. The support frame 1 slides more smoothly along the axis of the pipe 10. Several set screws 7 are provided on the support frame 1 for fixing the pipe 10. Several set screws 7 are threaded to the support frame 1. A fixing plate 6 is provided on the support frame 1. Several set screws 7 are threaded to the fixing plate 6. Tightening the set screws 7 fixes the pipe 10. When adjusting the position of the hoist, the set screws 7 are loosened and the hoist is moved along the axis of the pipe 10. Due to the setting of the rollers 5, the hoist can slide more smoothly.

[0022] In order to further increase the contact area between the set screw 7 and the pipe 10, a top block 9 is installed at one end of each set screw 7 near the pipe 10. The end face of the top block 9 is curved, flat or inclined. A screwing block 8 is provided at the other end of each set screw 7.

[0023] The support frame 1 and the connecting frame 2 are hinged together by the connecting shaft 4. The connecting frame 2 can swing more flexibly when suspended. The top of the connecting frame 2 is equipped with a lifting ring 3.

[0024] In summary, when using this pipe hoisting device, the pipe 10 is installed in the support frame 1, and then the set screw 7 is tightened to fix the pipe 10. Then the pipe 10 is suspended. If the pipe 10 is found to be slightly tilted, the set screw 7 is loosened and the hoisting device is moved to adjust the position of the hoisting device. After the adjustment is completed, the set screw 7 is used to fix the pipe 10.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
