Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower engineering, and particularly relates to a buried pipe device for water conservancy and hydropower engineering. Background Technique

[0002] Water conservancy and hydropower engineering is the general term for various projects aimed at controlling, utilizing, and protecting surface water resources and groundwater resources. The pipes used in water conservancy and hydropower engineering are generally buried underground. During the construction process, it is usually necessary to first dig a trench, and then use a buried pipe device to place the pipe into the trench for laying, and then bury the pipe after laying.

[0003] Chinese Patent with publication number CN216951975U discloses a buried pipe device for water conservancy and hydropower engineering, which includes a support platform. A blanking mechanism is arranged at the bottom of the support platform, and an adjusting mechanism is arranged on the outer surface of the support platform.

[0004] For the above-mentioned disclosed technology, after the pipes are placed and connected in the trench, it is still necessary for construction workers to backfill the trench manually or by construction machinery. When the existing trench is excavated, the excavated soil is often piled on both sides of the trench. Therefore, when personnel backfill it, they need to operate back and forth on both sides of the trench, which is inconvenient for the staff to work.

[0005] Therefore, a buried pipe device for water conservancy and hydropower engineering is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a buried pipe device for water conservancy and hydropower engineering to solve the problems raised in the above background technique.

[0007] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0008] A buried pipe device for water conservancy and hydropower engineering includes a trolley. A pipe handling mechanism is arranged on the top surface of the trolley, and a sling is arranged at the end of the pipe handling mechanism. Suspension rods are respectively inserted into both side walls of the sling. The buried pipe device further includes: a plurality of groups of pipe placement racks, which are arranged in an array on the top surface of the trolley; a tail frame, which is arranged at the tail of the trolley; a soil burying component, which is arranged inside the tail frame, and the position of the soil burying component is controlled by the tail frame to backfill the soil on both sides of the trench after burying the pipe.

[0009] Further, the pipe handling mechanism includes a gantry, which is fixedly installed on the top surface of the trolley. An electric push rod is installed on the gantry to push the U-shaped seat at its end to move horizontally. A motor is fixedly installed on one side wall of the U-shaped seat, and the output end of the motor is connected to a rotating shaft and used to drive the rotating shaft to rotate. A plurality of winches are fixedly sleeved on the surface of the rotating shaft, and hoisting steel cables are wound around the surfaces of the plurality of winches. The bottom end of the hoisting steel cable is fixedly installed with the top of the sling.

[0010] Further, the tail frame includes a bearing plate fixedly installed at the tail of the trolley, and through grooves are formed on the surface of the bearing plate. A rotating arm is rotatably installed on the top surface of the bearing plate, and a fastening bolt is inserted into the rotating arm. The fastening bolt is slidably arranged inside the through groove, and a folding arm is hingedly installed at the end of the rotating arm.

[0011] Further, the soil burying component includes a double-shaft motor, which is fixedly connected to the folding arm. Both output ends of the double-shaft motor are coaxially installed with extended shafts, and spiral augers are fixedly sleeved on the surfaces of the two extended shafts.

[0012] Further, one end of the pipe placement rack is in an inclined structure, and the other end is in an L-shaped structure.

[0013] Further, the rotation directions of the two spiral augers are opposite. When burying the pipe, the two spiral augers are respectively located on both sides of the trench, and the soil on both sides of the trench is backfilled into the trench by the rotation of the two spiral augers.

[0014] The beneficial effects of the present invention are as follows:

[0015] The device is moved to one side of the trench through the trolley. The lifting rods are inserted into both sides of the sling, so that the lifting rods are located inside the pipe orifices, and then the pipe can be lifted. By configuring the trolley with a pipe handling mechanism and a sling, the on-site handling process of the pipe is simplified, and manual handling is saved. By unfolding the tail frame, the soil burying component is located above. Moving the trolley enables the soil on both sides of the trench to be backfilled into the trench through the soil burying component, realizing direct and accurate covering of the backfill soil. There is no need for workers to frequently transport soil back and forth on both sides of the trench, greatly reducing the physical labor intensity and improving the operation efficiency.

[0026] As Figures 1 to 4 shown, a buried pipe device for water conservancy and hydropower projects includes a trolley 1. A pipe handling mechanism 3 is provided on the top surface of the trolley 1, and a sling 4 is provided at the end of the pipe handling mechanism 3. Suspension rods 41 are respectively inserted into the two side walls of the sling 4. The buried pipe device further includes: a pipe placement rack 2, configured in multiple groups and arranged in an array on the top surface of the trolley 1; a tail frame 5, provided at the tail of the trolley 1; a soil burying component 6, provided inside the tail frame 5, and the position of the soil burying component 6 is controlled by the tail frame 5 to backfill the soil on both sides of the trench after the pipe is buried.

[0027] In this embodiment, the pipes to be buried are stacked on the top surface of the pipe placement rack 2. The device is moved to one side of the trench through the trolley 1. The suspension rods 41 are inserted into both sides of the sling 4 so that the suspension rods 41 are located inside the pipe orifices, thereby enabling the pipes to be lifted and transported into the trench. By unfolding the tail frame 5, the soil burying component 6 is located above. The trolley 1 is moved so that the soil on both sides of the trench can be backfilled into the trench through the soil burying component 6.

[0028] In some practical applications, the pipe handling mechanism 3 includes a gantry 301 fixedly installed on the top surface of the trolley 1. An electric push rod 302 is installed on the gantry 301 to push the U-shaped seat 303 at its end to move horizontally. The movable part of the electric push rod 302 and the gantry 301 are movably inserted. A motor 304 is fixedly installed on one side wall of the U-shaped seat 303, and the output end of the motor 304 is connected to a rotating shaft 305 and is used to drive the rotating shaft 305 to rotate. A plurality of winches 306 are fixedly sleeved on the surface of the rotating shaft 305, and hoisting steel cables 307 are wound around the surfaces of the plurality of winches 306. The bottom end of the hoisting steel cable 307 and the top of the sling 4 are fixedly installed. More specifically, through the telescopic movement of the electric push rod 302, the sling 4 is horizontally moved. The motor 304 drives the rotating shaft 305 and the winches 306 to rotate. By the rotation of the winches 306, the hoisting steel cables 307 are wound and unwound, so as to adjust the vertical position of the sling 4 and lift the pipes into the trench.

[0029] In some practical applications, the tailstock 5 includes a bearing plate 501 fixedly installed at the tail of the trolley 1, and a through groove 502 is formed on the surface of the bearing plate 501. A rotating arm 503 is rotatably installed on the top surface of the bearing plate 501, and a fastening bolt 504 is inserted into the rotating arm 503. The fastening bolt 504 is slidably arranged inside the through groove 502, and a folding arm 505 is hingedly installed at the end of the rotating arm 503. More specifically, the position between the rotating arm 503 and the bearing plate 501 can be fixed by the fastening bolt 504. The folding arm 505 is unfolded so that the folding arm 505 and the rotating arm 503 are flush with each other, and the soil burying component 6 is located above the trench. It should be noted that after the folding arm 505 is unfolded and flush with the rotating arm 503, a limiting part or a limiting piece should be provided between the two, which is the prior art and is not specifically shown in the figure to ensure the unfolding angle of the folding arm 505 and the storage of the folding arm 505.

[0030] In some practical applications, the soil burying component 6 includes a double-shaft motor 601, which is fixedly connected to the folding arm 505. Both output ends of the double-shaft motor 601 are coaxially installed with extension shafts 602, and spiral augers 603 are fixedly sleeved on the surfaces of the two groups of extension shafts 602. More specifically, the double-shaft motor 601 drives the two groups of extension shafts 602 and the spiral augers 603 to rotate, and the spiral augers 603 rotate to backfill the soil on both sides of the trench into the trench to bury the pipeline.

[0031] In some practical applications, based on one or more of the above embodiments, one end of the pipeline placement rack 2 is of an inclined structure, and the other end is provided with an L-shaped structure. More specifically, since one end of the pipeline placement rack 2 is inclined, when a group of pipelines at the other end of the pipeline placement rack 2 are lifted, other pipelines can roll to the other end of the pipeline placement rack 2 under the action of gravity and are limited by the L-shaped structure.

[0032] In some practical applications, the rotation directions of the two groups of spiral augers 603 are opposite. When burying the pipeline, the two groups of spiral augers 603 are respectively located on both sides of the trench, and the two groups of spiral augers 603 rotate to drive the soil on both sides of the trench to be backfilled into the trench. More specifically, the two groups of spiral augers 603 with opposite rotation directions can gather the soil on both sides of the trench into the trench to achieve backfilling and burying.

[0033] In summary: Stack the pipes to be buried on the top surface of the pipe placement rack 2. Move the device to one side of the trench by means of the trolley 1. Insert the hanging rods 41 into both sides of the sling 4 so that the hanging rods 41 are located inside the pipe orifices, thereby enabling the pipes to be lifted and transported into the trench. Expand the tail frame 5 so that the soil burying assembly 6 is located above. Move the trolley 1 so that the soil on both sides of the trench can be backfilled into the trench through the soil burying assembly 6, achieving precise coverage of the backfill soil directly. There is no need for workers to frequently carry soil back and forth on both sides of the trench, greatly reducing the physical labor intensity and improving the operation efficiency.

[0034] The above are only embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
