Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline axil corner backfilling and compacting, in particular to a pipeline axil corner backfilling and compacting device. Background Art

[0002] During water conservancy construction, pipelines must be installed, consisting of numerous pipes. Specifically, the pipes used to dispatch water resources are often large-diameter and installed above ground. However, due to their cylindrical structure, the contact surface between the pipes and the horizontal ground is too small, resulting in low pipe support stability.

[0003] Therefore, in order to strengthen the stability of pipeline installation on the ground, the existing technology often fills the corners between the pipeline and the ground with soil. After the soil is filled in the corners, it needs to be compacted. This method ensures that the corners of the pipeline are supported by the compacted soil layer structure, thereby significantly improving the stability of the pipeline.

[0004] However, since the corner position between the large-diameter pipeline and the ground is relatively narrow, in the prior art, operators use a vibrator to compact the soil structure at an angle toward the corner position.

[0005] However, first of all, this method is difficult to construct. Specifically, because the axillary corner position is relatively narrow, once the tilt direction of the vibrator is not well controlled, it is difficult to fully compact the soil layer at the axillary corner position. Secondly, the pipeline structure is too long, resulting in a relatively large amount of compaction work. Finally, the efficiency of manual compaction is very low, and in order to ensure the stability of the soil layer after the axillary corner is compacted, it is often necessary to compact repeatedly, resulting in a very large overall workload. In the actual work process, a large amount of manpower is required during the compaction operation of the pipeline axillary corner, resulting in a significant increase in the cost of construction, and because the pipeline is long and the compaction speed is slow, it seriously affects the progress of the project. Therefore, how to make a pipeline axillary corner backfill compaction device that can solve the problems of the existing technology has become a technical problem to be solved. Utility Model Content

[0006] The present invention is based on the above technical problems and proposes a pipeline axil corner backfill compaction device to solve the problems existing in the above background technology.

[0007] In view of this, the utility model proposes a pipeline axil corner backfill compaction device, which includes: a crawling mechanism crawling on the pipeline, and hinged axil corner compaction mechanisms are respectively installed on both sides of the crawling mechanism; the crawling mechanism includes an arc-shaped climbing frame, and the axil corner compaction mechanism includes a connecting seat fixedly connected to the arc-shaped climbing frame, the connecting seat is hinged with a length adjustment rod, the length adjustment rod is detachably installed with a vibration motor, and the vibration motor is fixedly installed with a vibration compaction plate; the length adjustment rod includes an adjustment rod portion hinged on the connecting seat, and the adjustment rod portion is locked on the connecting seat by a locking structure; during the compaction process, the crawling mechanism crawls on the pipeline, and under the action of the vibration motor, the vibration compaction plate continuously vibrates and compacts the soil layer toward the axil corner of the pipeline.

[0008] Furthermore, the connecting seat is fixedly connected to the hinge seat, and the adjusting rod is hinged on the hinge seat through a fixed pin.

[0009] Furthermore, the length adjustment rod also includes a telescopic tube portion slidably connected to the adjustment rod portion, and the telescopic tube portion locks the adjustment rod portion through a plurality of locking screws; the telescopic tube portion is detachably fixedly connected to the vibration motor.

[0010] Furthermore, the locking structure includes a long adjustment slide opened on the adjustment rod, and the bottom of the connecting seat is fixedly connected with an inclined through screw, and the through screw passes through the long adjustment slide; the through screw is threadedly connected with a pair of nuts positioned on both sides of the adjustment rod.

[0011] Furthermore, the climbing mechanism also includes an inner conflict roller fixedly connected to the inner side wall of the arc-shaped climbing frame, and the inner conflict roller is distributed in an arc shape on the arc-shaped climbing frame.

[0012] Furthermore, the inner friction roller includes a roller fixing frame, and the roller fixing frame is rotatably connected to a friction wheel that rolls on the side wall of the pipe; the roller fixing frame is fixedly connected to a connecting screw, and the inner side wall of the arc-shaped climbing frame is fixedly connected to a threaded seat that is threadedly connected to the connecting screw.

[0013] Furthermore, the crawling mechanism also includes a plurality of driving roller assemblies fixedly connected to the outer side wall of the arc-shaped climbing frame; the driving roller assemblies roll against the outer side wall of the pipe.

[0014] Furthermore, the driving roller assembly includes a T-shaped wheel frame, and the two sides of the T-shaped wheel frame are rotatably connected to the external interference rollers; the two sides of the T-shaped wheel frame are fixedly installed with motors that drive the external interference rollers.

[0015] Furthermore, a sliding screw rod slidably connected to the T-shaped wheel frame is fixedly connected to the outer side wall of the arc-shaped climbing frame, and a contact nut for contacting and pressing the T-shaped wheel frame is threadedly connected to the sliding screw rod.

[0016] The utility model proposes a pipeline axil corner backfill compaction device, which has the following advantages compared with the existing technology:

[0017] 1. During operation, driven by the motor, friction is generated between the rotating outer friction roller and the pipe, thereby achieving crawling. During the crawling process, smooth movement is achieved under the arc-shaped distribution limit of the inner friction roller.

[0018] This method greatly improves the efficiency of compaction at the axillary corners, and enables back-and-forth movement on the pipe (the motor uses a forward and reverse motor) to achieve repeated compaction.

[0019] 2. During operation, the operator flips the length adjustment lever until the vibrating compaction plate is perpendicular to the soil structure filled at the pipe's axil angle. Then, the operator loosens the locking screw and slides the adjustment lever until the vibrating compaction plate is pressed against the soil structure. After locking, the operator turns on the vibration motor. At this time, under the action of the vibration motor, the vibrating compaction plate continuously vibrates and compacts the soil layer (using the vibration motor to generate vibration force on the vibrating compaction plate and compact the soil layer through vibration is one of the conventional applications of vibration motors in the prior art). The continuous crawling of the crawling mechanism achieves continuous compaction, and the crawling process continues, thereby greatly improving the compaction effect of the pipe's axil angle.

[0020] 3. The use of the utility model in the process of compacting the pipe axillary corners can greatly reduce manpower input, improve construction efficiency, reduce construction costs, and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the contents disclosed below.

[0029] The following combination Figures 1 to 5 The technical solution of the utility model is further explained.

[0030] The first embodiment, as Figures 1 to 5 A device for backfilling and compacting pipe corners is shown. It includes a crawling mechanism that crawls on a pipe 1, with hinged corner compacting mechanisms mounted on either side of the crawling mechanism. Specifically, by automatically crawling on the pipe 1 and compacting as it goes, the device eliminates the need for manual operation. This significantly improves efficiency and reduces labor costs for compacting the corners of long pipes 1.

[0031] Specifically, the climbing mechanism includes an arc-shaped climbing frame 21, which also includes an inner friction roller 26 fixedly connected to the inner side wall of the arc-shaped climbing frame 21. The inner friction roller 26 is distributed in an arc shape on the arc-shaped climbing frame 21. Specifically, the inner friction roller 26 includes a roller fixing frame, on which a friction wheel that rolls against the side wall of the pipeline 1 is rotatably connected; the roller fixing frame is fixedly connected to a connecting screw, and a threaded seat that is threadedly connected to the connecting screw is fixedly connected to the inner side wall of the arc-shaped climbing frame 21.

[0032] The crawling process is achieved by the inner friction roller 26. Under the limitation of the inner friction roller 26, the crawling stability is maintained. Specifically, the arc-shaped inner friction roller 26 is adapted to the shape of the pipe 1. Under the arc-shaped distribution, the movement trajectory is kept from deviating during the crawling process and the subsequent vibration compaction process.

[0033] The above-mentioned climbing mechanism also includes a plurality of driving roller assemblies fixedly connected to the outer wall of the arc-shaped climbing frame 21; the driving roller assemblies are similarly distributed in an arc shape. Specifically, the driving roller assemblies roll against the outer wall of the pipeline 1.

[0034] The specific structure of the driving roller assembly is as follows: the driving roller assembly includes a T-shaped wheel frame 22, and the two sides of the T-shaped wheel frame 22 are respectively rotatably connected to the outer contact rollers 23; the two sides of the T-shaped wheel frame 22 are respectively fixedly installed with motors 24 that drive the outer contact rollers 23.

[0035] Specifically, similar to the existing method, one side of the outer contact roller 23 is rotatably connected to the T-shaped wheel frame 22 via a rotating shaft, and the output shaft of the motor is fixed to the other side of the outer contact roller 23 .

[0036] At the same time, a connecting seat is welded on the outer side wall of the T-shaped wheel frame 22, and the motor is fastened to the connecting seat by a screw to achieve fixed installation of the motor 24.

[0037] During operation, driven by the motor 24, frictional power is generated between the rotating outer friction roller 23 and the pipe 1, thereby achieving crawling. During crawling, smooth movement is achieved under the arc-shaped distribution limit of the inner friction roller 26.

[0038] This method greatly improves the efficiency of compaction at the axillary corners, and enables back-and-forth movement on the pipe 1 (the motor 24 uses a forward and reverse motor 24 ) to achieve repeated compaction.

[0039] At the same time, to maintain the stable contact pressure of the outer contact roller 23 against the pipe 1, a sliding screw 25 is fixedly connected to the outer wall of the curved climbing frame 21 and is slidably connected to the T-shaped wheel frame 22. The sliding screw 25 is threadedly connected to a contact nut 251 that contacts and presses the T-shaped wheel frame 22. The operator screws the contact nut 251 downward to push the T-shaped wheel frame 22 until the outer contact roller 23 on the T-shaped wheel frame 22 contacts and presses tightly against the pipe 1, maintaining the stability of the movement and avoiding the defect that the outer contact roller 23 is prone to slipping due to insufficient contact pressure.

[0040] The second embodiment, as Figures 1 to 5 As shown, the difference from the above embodiment is that in order to achieve compaction of the axillary corners of the pipeline 1, the axillary corner compaction mechanism includes a connecting seat 36 fixedly connected to the arc-shaped climbing frame 21 (the connecting seat 36 is fixed by vertical welding), the connecting seat 36 is hinged with a length adjustment rod, the length adjustment rod is detachably mounted with a vibration motor 32, and the vibration motor 32 is fixedly mounted with a vibration compaction plate 31.

[0041] Specifically, similar to the existing method, the vibration motor 32 is fixedly installed on the vibration compacting plate 31 through the U-shaped rod 321.

[0042] Specifically, the length adjustment rod includes an adjustment rod portion 34 hinged on the connecting seat 36, and the adjustment rod portion 34 is locked on the connecting seat 36 through a locking structure; during the compaction process, the crawling mechanism crawls on the pipe 1, and under the action of the vibration motor 32, the vibration compaction plate 31 continuously vibrates and compacts the soil layer toward the axillary corner of the pipe 1.

[0043] Specifically, the connecting seat 36 is fixedly connected to the hinge seat 35 , and the adjusting rod 34 is hinged on the hinge seat 35 via a fixed pin.

[0044] At the same time, the length adjustment rod also includes a telescopic tube portion 33 that is slidably connected to the adjustment rod portion 34 (a column cavity is opened in the adjustment rod portion 34, and the adjustment rod portion 34 slides in the column cavity), and the telescopic tube portion 33 locks the adjustment rod portion 34 through a plurality of locking screws; the telescopic tube portion 33 and the vibration motor 32 are detachably fixedly connected (specifically, the length adjustment rod is fixedly connected to the upper mother mounting plate 38. The mother mounting plate 38 is fastened to the frame plate 322 of the vibration motor 32 by bolts).

[0045] During operation, the operator flips the length adjustment rod until the vibrating compaction plate 31 is perpendicular to the soil structure filled at the corner of the pipe 1. Then, the operator loosens the locking screw and slides the vibrating compaction plate 31 to adjust the length until it is pressed against the soil structure. After locking, the vibration motor 32 is turned on. At this time, under the action of the vibration motor 32, the vibrating compaction plate 31 continuously vibrates and compacts the soil layer (using the vibration motor 32 to generate a vibration force on the vibrating compaction plate 31 and compacting the soil layer through vibration is one of the conventional applications of the vibration motor 32 in the prior art). The continuous crawling of the crawling mechanism achieves continuous compaction and continuous crawling, thereby greatly improving the compaction effect of the corner of the pipe 1.

[0046] The third embodiment, as Figures 1 to 5 As shown, the difference from the above embodiment is that: when the length adjustment rod is flipped to a certain angle, in order to keep the length adjustment rod and the vibration compaction plate 31 in a fixed posture, the above locking structure includes a long adjustment slide 341 opened on the adjustment rod portion 34, and the bottom of the connecting seat 36 is fixedly connected with an inclined through screw 37, and the through screw 37 passes through the long adjustment slide 341; the through screw 37 is threadedly connected with a pair of nuts 371 positioned on both sides of the adjustment rod portion 34.

[0047] During the flipping process of the length adjustment rod, the adjustment rod 34 moves relative to the through screw 37, and the through screw 37 passes through the long adjustment slide 341. Then the operator screws the nut 371 toward the adjustment rod 34 until it is squeezed and positioned on both sides of the adjustment rod 34.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
