Description

Technical Field

[0001] This utility model relates to the field of pipeline backfilling technology, specifically to a backfilling and compaction device for pipeline axle corners. Background Technology

[0002] In water conservancy construction sites, pipe installation is inevitable. Pipes have curved surfaces, and the backfilling quality is particularly difficult to guarantee at the pipe's underside. The pipe's underside refers to the gap at the bottom of the pipe's curved surface.

[0003] Existing technology uses manual methods to backfill pipelines. During the multiple compaction processes in the narrow space of the pipeline axle, the workers' backfilling and compaction movements are restricted due to the axle being at the bottom of the pipeline, and the low position makes it difficult to exert force. This results in high labor intensity and low efficiency for the workers. Utility Model Content

[0004] The purpose of this invention is to provide a backfilling and compaction device for pipe haunches to solve the problems in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A backfill compaction device for pipe axle corners includes a base, a fixed bracket mounted on the base, one or more hydraulic push rods mounted on the fixed bracket, and the one or more hydraulic push rods are connected to a backfill pressure plate; the front of the backfill pressure plate is used for compression backfilling, and a vibration motor is mounted on the back of the backfill pressure plate.

[0006] Furthermore, there are four hydraulic push rods, which are respectively connected to the four corners of the backfill pressure plate.

[0007] Furthermore, the specific connection structure of the hydraulic push rod connected to the backfill pressure plate is as follows: a sleeve is provided on the backfill pressure plate, the piston rod of the hydraulic push rod is located inside the sleeve, a first spring is provided inside the sleeve, one end of the first spring is connected to the inner wall of the sleeve, the other end of the first spring is connected to the limiting block, and the limiting block is fixedly connected to the piston rod of the hydraulic push rod.

[0008] Furthermore, the base is equipped with casters at its bottom.

[0009] Furthermore, the base is provided with a pedal, and the bottom of the pedal is connected to two or more connecting rods. The connecting rods pass through the base and are connected to a fixing plate, which is located below the base. The bottom of the fixing plate is provided with multiple fixing rods. The bottom of the pedal is also connected to a second spring, which is connected to the base.

[0010] Furthermore, the backfill plate is provided with a vertically sliding unfolding plate, with both the upper and lower ends of the unfolding plate extending out of the backfill plate; the backfill plate is provided with a strip-shaped locking groove, and a locking bolt is provided in the strip-shaped locking groove, which is used to lock the unfolding plate.

[0011] Furthermore, a push handle is installed on the fixed bracket.

[0012] Compared with the prior art, this utility model has the following advantages and beneficial effects: By installing hydraulic push rods on the base, the backfill plate is pushed to compact the soil. Compared to manual backfilling, the hydraulic push rods and backfill plate can operate at a lower position, fitting the position of the axle. The linear movement of the hydraulic push rods results in smaller backfilling movements, making it easier to backfill within the pipe axle. After the backfilling work is completed, the backfill plate presses against the pipe and the backfilled soil. A vibration motor continuously vibrates the backfill plate to compact the soil, thereby reducing the labor intensity of workers and improving the efficiency of backfilling and compaction.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0019] like Figure 1 , Figure 3As shown, a backfill compaction device for a pipe axle includes a base 1, a fixed bracket 2 installed on the base 1, and one or more hydraulic push rods 3 installed on the fixed bracket 2. The one or more hydraulic push rods 3 are connected to a backfill pressure plate 4. The front of the backfill pressure plate 4 is used for pressing backfill, and a vibration motor 5 is installed on the back of the backfill pressure plate 4.

[0020] The base 1 and the fixed bracket 2 form the main body of this utility model. When backfilling and compaction are required, the base 1 is moved to a suitable position, and then the corresponding controller is operated to control the start of the hydraulic push rod 3 and the vibration motor 5. The process is carried out in steps: the soil is manually poured between the pipe armpit and the backfilling plate 4, and then the hydraulic push rod 3 is started to backfill the soil to the pipe armpit. After the backfilling is completed, the backfilling plate 4 is pressed onto the soil at the pipe bend, and the vibration motor 5 is started. The vibration force generated by the vibration motor 5 compacts the soil, completing the compaction operation and ensuring the strength of the compaction. The backfill plate 4 is pushed by a hydraulic pusher 3 to compact the soil. Compared to manual backfilling, the hydraulic pusher 3 and backfill plate 4 can operate at a lower position, fitting the position of the pipe axle. The linear movement of the hydraulic pusher 3 results in minimal backfilling action, facilitating backfilling within the pipe axle. After backfilling, the backfill plate 4 presses against the pipe and the backfilled soil. A vibration motor 5 continuously vibrates the backfill plate 4, compacting the soil and reducing the labor intensity of workers, thus improving the efficiency of backfilling and compaction. This invention is commonly used on construction sites where there is ample horizontal space to place it during pipe backfilling, facilitating horizontal backfilling of the pipe axle.

[0021] Furthermore, there are four hydraulic push rods 3, which are respectively connected to the four corners of the backfill plate 4. The four hydraulic push rods 3 connected to the four corners of the backfill plate 4 ensure the stability of the backfill plate 4 during the pushing process.

[0022] like Figure 4As shown, further, the specific connection structure of the hydraulic push rod 3 connected to the backfill plate 4 is as follows: a sleeve 6 is provided on the backfill plate 4, the piston rod of the hydraulic push rod 3 is located inside the sleeve 6, a first spring 7 is provided inside the sleeve 6, one end of the first spring 7 is connected to the inner wall of the sleeve 6, and the other end of the first spring 7 is connected to the limiting block 8, which is fixedly connected to the piston rod of the hydraulic push rod 3. The vibration motor 5 is installed on the backfill plate 4, and the backfill plate 4 and the hydraulic push rod 3 are elastically connected through the first spring 7; the vibration generated by the vibration motor 5 is transmitted to the base 1 and the fixed bracket 2 through the hydraulic push rod 3. The base 1 and the fixed bracket 2 are used to determine the foundation orientation of the backfill compaction, and the vibration will affect the position of the base 1 and the fixed bracket 2. The elastic connection of the first spring 7 prevents the vibration motor 5 from directly transmitting to the base 1 and the fixed bracket 2. The vibration motor 5 drives the backfill plate 4 to vibrate, while the vibration affecting the base 1 and the fixed bracket 2 is relatively small. The first spring 7 is a damped spring that can absorb and dissipate vibration force through deformation, preventing the vibration force from being transmitted to the hydraulic push rod 3 and causing damage. For the backfilling plate 4, after the vibration motor 5 stops working, absorbing and dissipating the vibration force can stop the vibration of the backfilling plate 4 in a short time.

[0023] Furthermore, the base 1 is equipped with rollers 9 at its bottom, which facilitates the transfer of this utility model.

[0024] like Figure 2 As shown, the base 1 is further equipped with a pedal 10. Two or more connecting rods 11 are connected to the bottom of the pedal 10. The connecting rods 11 pass through the base 1 and are connected to a fixing plate 12, which is located below the base 1. Multiple fixing rods 13 are provided at the bottom of the fixing plate 12. A second spring 14 is also connected to the bottom of the pedal 10 and is connected to the base 1. When the worker steps on the pedal 10, the pedal 10, connecting rods 11, and fixing plate 12 move downwards together, causing the fixing rods 13 at the bottom of the fixing plate 12 to insert into the ground, thus fixing the base 1 and preventing it from moving due to the vibration of the rollers 9 or the vibration motor 5. After the backfilling and compaction work is completed, the worker releases the pedal 10. The second spring 14, under its elastic force, lifts the pedal 10, causing the fixing rods 13 to detach from the ground.

[0025] Furthermore, the backfill pressure plate 4 is provided with a vertically sliding unfolding pressure plate 15, with both the upper and lower ends of the unfolding pressure plate 15 extending out of the backfill pressure plate 4. The backfill pressure plate 4 is provided with a strip-shaped locking groove 16, within which a locking bolt 17 is installed. The locking bolt 17 is used to lock the unfolding pressure plate 15. When dealing with pipes of different heights, the unfolding pressure plate 15 can be adjusted vertically, and then fixed and locked using the locking bolt 17.

[0026] Furthermore, a push handle 18 is installed on the fixed bracket 2, which facilitates the movement of this utility model by the staff.
