Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cable burying, and particularly relates to a portable cable auxiliary laying device. BACKGROUND

[0002] When laying an underground cable, a trench is generally first dug, the cable is laid on the trench bottom, and then the overburden is backfilled. There are two common ways to dig the trench: one is to directly dig the trench on the land, and the other is to first loosen the soil with a slightly larger width, and then dig the trench in the loosened soil. The second way is not only less difficult, but also the front loosening mechanism can use existing loosening vehicles, and only a separate trench digging device for loosened soil is needed, which is lower in research and development difficulty, use difficulty and cost pressure.

[0003] There are two common ways to dig a trench in loosened soil: one is to roll by a solid metal wheel, and the other is to throw the soil in the trench to both sides of the trench. Since the cable needs to be backfilled after laying, the second way is more suitable.

[0004] This way is not difficult, but there is a more significant problem, that is, since the cable burying has a certain requirement for the depth of the trench, but not for the width, the stability of the deep and narrow trench wall in the loosened soil is poor during the interval between the two steps of trench digging and laying, and the soil on both sides is easy to collapse and fill the trench bottom in advance, thereby causing the actual burying depth to be substandard.

[0005] In addition, this portable auxiliary laying device is generally a separate mechanism temporarily installed at the rear of an existing loosening vehicle, so how to drive and connect will significantly affect the convenience of using the device, which is also a problem that needs to be considered in the design of the device. SUMMARY

[0006] In view of the above situation, in order to simplify the structure, the application provides a portable cable auxiliary laying device, which integrates the two originally independent steps of trench digging and cable laying, which can not only simplify the structure and operation steps, but also avoid the problem of deep trench sidewall collapse; the present application utilizes the movement of the cable release to automatically drive the reverse rotation of the split digging assembly, thereby automatically achieving the technical effect of trench digging before burying.

[0007] Through the automatic closing and unfolding of the split digging assembly, the split digging assembly is automatically closed when it travels to the excavation working area (to excavate the target position), and is automatically unfolded when it leaves the excavation working area (both the soil can be thrown to both sides, and the swing shovel can also avoid damaging the cable surface).

[0008] Moreover, the elastic deformation of the elastic buckle allows the cable to be buckled into the elastic buckle and establish a stable rolling connection with the buckle guide wheel, and since the excavation resistance of the soft soil is small, the release of the cable can stably drive the excavation and burying mechanism to rotate; solve the connection stability problem when the outer gear ring rotates with the cable.

[0009] The technical scheme adopted by the present application is as follows: the present application provides a portable cable auxiliary laying device, comprising a rack, an excavation and burying mechanism, a height adjusting mechanism and a winding assembly, the excavation and burying mechanism is arranged on the height adjusting mechanism, the height adjusting mechanism is arranged on the rack, and the winding assembly is arranged on the rack.

[0013] Through the structural design of the center gear and the outer gear ring, the external turntable can be reversely rotated at a speed greater than that of the cable release, so that a trench for burying the cable can be dug in the soft soil by the separate excavation assembly before the cable reaches the pre-burying position.

[0014] As a further preferred of the present application, the separate excavation assembly comprises a swing base and a swing shovel, the swing base is fixedly connected to the external turntable, a spring base is arranged on the swing base, the swing shovel is rotatably arranged on the swing base, both ends of the swing shovel are respectively provided with a shovel blade part and a shovel root part, and a spring sheet is arranged between the spring base and the shovel root part.

[0018] Since the cable has a tensioning tendency, when the cable and the outer gear ring are combined, the cable can overcome the elastic force of the elastic buckle and enter the elastic buckle, and the cable and the buckle guide wheel establish a stable rolling connection relationship; in the case of rolling connection between the buckle guide wheel and the cable, the cable can easily enter the elastic buckle, so as to realize the rolling contact between the cable and the outer gear ring, and further enable the release of the cable to drive the rotation of the outer gear ring.

[0019] Among them, the elastic sheet and the elastic buckle are elastic metal materials.

[0048] As shown in Figures 1 to 12 The present application provides a portable cable auxiliary laying device, comprising a rack 1, a digging and burying mechanism 2, a height adjusting mechanism 3 and a winding assembly 4, the digging and burying mechanism 2 is arranged on the height adjusting mechanism 3, the height adjusting mechanism 3 is arranged on the rack 1, and the winding assembly 4 is arranged on the rack 1.

[0049] The digging and burying mechanism 2 comprises a special-shaped partition fork 5, a driven rotating assembly 6, a reversing assembly 7 and a digging assembly 8, the special-shaped partition fork 5 is arranged on the height adjusting mechanism 3, the driven rotating assembly 6 is rotatably arranged in the special-shaped partition fork 5, the reversing assembly 7 is rotatably arranged in the special-shaped partition fork 5, and the digging assembly 8 is annularly and uniformly arranged on the reversing assembly 7.

[0050] The digging and burying mechanism 2 can be driven through the release process of the cable 29, so as to automatically realize the trench digging in the soft soil and the burying of the cable 29.

[0051] The special-shaped partition fork 5 is arranged on the height adjusting mechanism 3, the special-shaped partition fork 5 is provided with a central hole 9, the reversing assembly 7 comprises a central gear 16 and an outer rotating disc 31, the central gear 16 is provided with a central shaft 20, the digging and burying mechanism 2 is rotatably arranged in the central hole 9, and the outer rotating disc 31 is fixedly connected to two ends of the central shaft 20.

[0052] Through the structural design of the central gear 16 and the outer gear ring 12, the outer rotating disc 31 can be reversely rotated at a speed greater than that of the cable 29 release, so that a trench for burying the cable 29 can be dug in the soft soil by the digging assembly 8 before the cable 29 reaches the pre-burying position.

[0053] The digging assembly 8 comprises a swing base 17 and a swing shovel 18, the swing base 17 is fixedly connected to the outer rotating disc 31, the swing base 17 is provided with a spring base 30, the swing shovel 18 is rotatably arranged on the swing base 17, two ends of the swing shovel 18 are respectively provided with a shovel blade part 21 and a shovel root part 32, and the spring base 30 and the shovel root part 32 are provided with a spring 19.

[0054] The entire movement track of the trenching assembly 8 is divided into a closed area and an expanded area by the special partitioning fork 5, the trenching assembly 8 can excavate soft soil in the closed area, and the excavated sand is thrown to both sides of the trench in the expanded area; moreover, the cable 29 laid can be prevented from being damaged by the swinging shovel 18 by keeping the expanded state.

[0055] The special partitioning fork 5 is also provided with eccentric holes 10 arranged in a ring shape and uniformly distributed, and the reverse assembly 7 further comprises an idler gear 15, which is rotatably arranged in the eccentric holes 10, and the idler gear 15 and the center gear 16 are in meshing transmission.

[0056] The driven rotating assembly 6 comprises a support ring 11, an outer gear ring 12 and an elastic buckle 13, the support ring 11 is fixedly connected to the inner wall of the special partitioning fork 5, the support ring 11 and the center gear 16 are coaxially arranged, the outer gear ring 12 is rotatably arranged on the support ring 11, the outer gear ring 12 and the idler gear 15 are in meshing transmission, and the elastic buckle 13 is arranged in a ring shape and uniformly distributed on the outer wall of the outer gear ring 12, and the end of the elastic buckle 13 is symmetrically provided with a buckle guide wheel 14.

[0057] Since the cable 29 has a tensioning tendency, when the cable 29 is combined with the outer gear ring 12, the cable 29 can overcome the elastic force of the elastic buckle 13 and enter the elastic buckle 13, and a stable rolling connection relationship between the cable 29 and the buckle guide wheel 14 is established; in the case of rolling connection between the buckle guide wheel 14 and the cable 29, the cable 29 can easily enter the elastic buckle 13, so as to realize the rolling contact between the cable 29 and the outer gear ring 12, and further enable the release of the cable 29 to drive the outer gear ring 12 to rotate.

[0058] The elastic sheet 19 and the elastic buckle 13 are made of elastic metal material.

[0059] The height adjusting mechanism 3 comprises a transversely arranged fork 22, a fork shaft 23 and a push rod assembly 24, the fork shaft 23 is fixedly connected to the rack 1, one end of the transversely arranged fork 22 is rotatably arranged on the fork shaft 23, and the center shaft 20 is rotatably arranged at the other end of the transversely arranged fork 22.

[0060] By the active extension and contraction of the telescopic push rod 25, the swinging of the transversely arranged fork 22 can be controlled, so as to control the excavation depth of the trench and the burying depth of the cable 29.

[0061] The push rod assembly 24 comprises the telescopic push rod 25 and a hinged device 26, the telescopic push rod 25 is arranged on the special partitioning fork 5, and the top end of the telescopic push rod 25 is connected to the rack 1 through the hinged device 26.

[0062] The winding assembly 4 comprises a winding shaft 27 and a winding disc 28, the winding shaft 27 is arranged on the rack 1, the winding disc 28 is rotatably arranged on the winding shaft 27, and the cable 29 is wound on the winding disc 28.

[0063] The rolling contact between the cable 29 and the buckle guide wheel 14, the unwinding part of the cable 29 can enter the inside of the elastic buckle 13 through the elastic deformation of the elastic buckle 13.

[0064] As shown in the figure, the angle range where α is located represents the working range of trench excavation, the arc-shaped arrow represents the rotation direction of the external rotating disc 31 and the sub-excavation assembly 8, the horizontal arrow represents the moving direction of the traction vehicle, and the dotted trajectory on the rightmost side represents the layer-by-layer scraping type of excavation form of the swing shovel 18; Figure 13

[0065] In the angle range where α is located, the cable 29 enters the elastic buckle 13 and maintains rolling contact with the buckle guide wheel 14, and the cable 29 and the outer ring gear 12 are in close contact and rolling contact; in the remaining range, the cable 29 is located outside the elastic buckle 13, and the cable 29 is also not in close contact with the outer ring gear 12;

[0066] In the angle range where α is located, the swing shovel 18 is in a closed state, and this area is also the excavation working area of the swing shovel 18; in the remaining range, the swing shovel 18 is in an unfolded state under the support of the special-shaped sub-fork 5, and this area is not the excavation working area of the swing shovel 18.

[0067] In specific use, the device is installed on the original soil loosening vehicle through the rack 1, one end of the cable 29 is released for a distance and fixed to the ground, and then the traction vehicle is started, so that the device can be driven together with the front soil loosening mechanism to move away from the fixed point of the cable 29, and in the process of vehicle movement, the cable 29 will be first tensioned and close to the outer ring gear 12 due to the resistance of the rotation of the winding disc 28 on the winding shaft 27, so that the cable 29 in the angle range of α will make the elastic buckle 13 elastically deform and enter the inside of the elastic buckle 13, so as to establish a rolling connection relationship with the buckle guide wheel 14. Figure 10

[0068] Since there is no relative sliding between the buckle guide wheel 14 and the cable 29, when the traction vehicle moves, the cable 29 continuously releases and unwinds, and through the clamping of the elastic buckle 13 to the cable 29, the outer ring gear 12 can be rotated.

[0069] Since the excavation resistance of soft soil is small, and the construction method of the present scheme is to gradually excavate a small amount of times by multiple sub-excavation assemblies 8, the release of the cable 29 can stably drive the excavation burying mechanism 2 to rotate.

[0070] ​​The outer gear ring 12 meshes with the idler gear 15, and the idler gear 15 meshes with the center gear 16, so that when the outer gear ring 12 rotates, the center gear 16 rotates in the opposite direction and at a speed greater than that of the outer gear ring 12, and rotates with the outer rotary disc 31 and the trenching assembly 8 on both sides;

[0071] The swing shovel 18 in the angle range of α is in a closed state, and the swing shovel 18 in the remaining range is in an unfolded state, that is, in front of the direction of travel, the closed swing shovel 18 excavates a trench, and after leaving the angle range of α, the swing shovel 18 is unfolded under the support of the special-shaped sub-fork frame 5, which can avoid collision damage to the cable 29 and throw the excavated sand to both sides; Figure 10

[0072] Subsequently, the cable 29 is laid in the trench just excavated.

[0073] When the depth of excavation and burial needs to be adjusted, the extension and retraction of the telescopic push rod 25 is actively controlled, the swing angle of the transverse fork frame 22 is controlled, and the longitudinal height of the trenching and burying mechanism 2 is adjusted.

[0074] As another new embodiment of the present application: after laying, the floating soil just excavated on both sides can be gathered towards the trench again through the bulldozing plate at the tail, so as to bury the cable 29.

[0075] It should be noted that the relational terms herein such as first and second and the like are used only to differentiate one entity or operation from another, and do not necessarily require or imply that these entities or operations exist in any actual relationship or order. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus including a series of elements includes not only those elements, but also other elements not explicitly listed or inherent to such a process, method, article or apparatus.

[0076] The above describes the present application and its embodiments, which are not limited, and the drawings only show one of the embodiments of the present application, and the actual structure is not limited thereto. In general, if a person skilled in the art is inspired by it, without departing from the purpose of the present application, similar structural modes and embodiments can be designed without creativity, which should belong to the protection scope of the present application.​
