Description

Technical Field

[0001] This application relates to the technical field of pipeline laying, and in particular to a pre-embedded pipeline installation device. Background Technology

[0002] During the laying of existing pipelines, the foundation is not completely flat, so leveling work is required during the connection process. Only after leveling can the pipelines be connected and the surrounding soil be filled. Since pipelines are usually heavy, cranes or similar equipment are generally needed for assistance, but the cost of using cranes is high, making the total cost of laying the pipeline considerable. Therefore, to solve the above problems, this application provides a pre-embedded pipeline installation device. Utility Model Content

An electric hoist is installed at the middle section of the side of the gantry frame, and a sliding rod connected to the chain segment of the electric hoist is slidably connected to the vertical section of the side of the gantry frame. A load-bearing band is provided between the two sliding rods to support the pipe. The electric hoist rotates clockwise and counterclockwise to control the vertical height adjustment of the pipe.

[0005] By setting up a gantry with electric hoists on both sides, and forming a rectangular load-bearing structure between the two electric hoists via a sliding rod and a load-bearing belt, the load-bearing effect on the pipeline can be achieved. The vertical height of the pipeline can be adjusted by rotating the electric hoists clockwise and counterclockwise.

[0006] Preferably, a rotating shaft is rotatably connected at the corner position at the top of the gantry, the rotating shaft connects two adjacent gantry, the load-bearing belt passes through the two rotating shaft positions in sequence, and supports the pipeline at the position between the rotating shafts.

[0007] Preferably, a guide frame is welded to the outer side of the vertical section of the gantry, and both ends of the sliding rod are slidably embedded in the inner side of the guide frame.

[0008] Preferably, both ends of the load-bearing belt are provided with connecting buckles, and the load-bearing belt is fastened to the sliding rod through the connecting buckles.

[0009] Preferably, counterweights are welded to the bottom of each gantry, and the bottom of each counterweight is movably connected to a track wheel.

[0010] Preferably, the electric hoist is installed between two counterweights on the same side.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By setting up a gantry with electric hoists on both sides, and forming a rectangular load-bearing structure between the two electric hoists via a sliding rod and a load-bearing belt, the load-bearing effect on the pipeline can be achieved. The vertical height of the pipeline can be adjusted by rotating the electric hoists clockwise and counterclockwise. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0019] Example 1:

[0020] A pre-embedded pipe installation device, referring to Figure 1 - Figure 4 An embedded pipe installation device includes at least two gantry frames 1, which are combined to form a three-dimensional rectangular structure. Counterweights 2 are welded to the bottom of each gantry frame 1, and track wheels 3 are movably connected to the bottom of each counterweight 2.

[0021] An electric hoist 5 is installed in the middle of the side of the gantry 1. A sliding rod 7 connected to the chain segment of the electric hoist 5 is slidably connected to the vertical section of the side of the gantry 1. A load-bearing belt 8 is installed between the two sliding rods 7 to support the pipeline. The electric hoist 5 rotates clockwise and counterclockwise to control the vertical height adjustment of the pipeline.

[0022] By setting up a gantry 1, with electric hoists 5 on both sides of the gantry 1, and the two electric hoists 5 forming a rectangular load-bearing structure through a sliding rod 7 and a load-bearing belt 8, the load-bearing effect on the pipeline can be achieved. The vertical height of the pipeline can be adjusted by rotating the electric hoists 5 clockwise and counterclockwise.

[0023] A rotating shaft 4 is rotatably connected at the top corner of the gantry 1. The rotating shaft 4 connects two adjacent gantry 1s. The load-bearing belt 8 passes through the two rotating shafts 4 in sequence, and supports the pipeline between the rotating shafts 4. The load-bearing belt 8 has an M-shaped structure when viewed from the front. The pipeline is supported in the middle position, and the two higher points are located at the rotating shafts 4. The rotating shafts 4 act as fixed pulleys for steering. The bottom positions on both sides of the load-bearing belt 8 are controlled by electric hoists 5. When the bottom positions on both sides move upward, the pipeline moves downward, and when the bottom positions on both sides move downward, the pipeline moves upward.

[0024] A guide frame 6 is welded to the outside of the vertical section of the gantry 1. Both ends of the sliding rod 7 are slidably embedded in the inside of the guide frame 6. Limiting blocks are set at both ends of the sliding rod 7 to ensure that the sliding rod 7 is always in a horizontal state.

[0025] Both ends of the load-bearing belt 8 are equipped with connecting buckles 9. The load-bearing belt 8 is fastened to the sliding rod 7 through the connecting buckles 9. The connecting buckles 9 are existing safety buckle structures. Before use, the sliding rod 7 is moved up one distance, and the connecting buckles 9 are removed from the sliding rod 7. Then, one end of the pipe is lifted, and the load-bearing belt 8 is placed below the pipe. The two ends of the load-bearing belt 8 are then passed through the two rotating shafts 4 and fastened to the sliding rod 7. After both load-bearing belts 8 are connected, the electric hoist 5 pulls the sliding rod 7 downward, slightly lifting the pipe. With the action of the track wheels 3, the pipe is transferred to the buried pipe position and lowered into the foundation pit for docking. Since the excavation of the pipe foundation pit is not completed in one go, the track wheels 3 do not need to cross the foundation pit. If it is necessary to cross the foundation pit, a temporary bridge can be built using support plates to complete the transfer of the track wheels 3. The adjustment of the electric hoist 5 is controlled by the on-site personnel via remote control.

[0026] The electric hoist 5 is installed between two counterweights 2 on the same side. If there is a need to adjust the inclination of the pipe, two sets of this device structure can be used, placed at both ends of the pipe, to work together.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
