Description

Technical Field

[0001] The present invention belongs to the technical field of slope protection, and specifically relates to a slope protection device for thermal pipeline construction in a complex environment. Background Technique

[0002] During the construction of thermal pipelines in a complex environment, problems such as tight construction periods and high construction difficulties are often faced. However, as a key component of the urban heating system, the construction progress and efficiency of thermal pipelines directly affect the heating guarantee of the entire city.

[0003] During the construction of thermal pipelines, before the construction of thermal pipelines, it is first necessary to excavate the soil in the pipeline laying area. During this process, the depth and width of the excavation will be determined according to the design requirements and geological conditions. During the excavation process, as the soil is gradually removed, the slope gradually forms. Construction workers will gradually adjust the excavation direction and depth according to the predetermined slope and soil conditions to ensure that the slope gradient meets the design requirements.

[0004] In the construction of thermal pipelines in a complex environment, the angles of the slopes are often different. If the angle of the protection device remains fixed, it will be very difficult to adapt to slopes of different angles. If the protection device cannot adapt to the slope angle, it will greatly increase the construction difficulty. Construction workers may need to spend more time and energy to adjust and fix the device, and may even need to customize a device with a special shape to adapt to the slope angle. Therefore, a slope protection device for thermal pipeline construction in a complex environment is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a slope protection device for thermal pipeline construction in a complex environment to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A slope protection device for thermal pipeline construction in a complex environment, including a bottom plate, a fixed ear is fixedly connected to the upper surface of the bottom plate, a rotating shaft is rotatably connected inside the fixed ear, a first fixed frame is fixedly connected to the surface of the rotating shaft, a first gear is fixedly connected to the surface of the rotating shaft, a fixed shell is fixedly connected to the upper surface of the bottom plate, a first rotating shaft is rotatably connected inside the fixed shell, second gears are fixedly connected to both ends of the first rotating shaft, and the second gears are meshed with the first gear, and a driving structure is arranged inside the fixed shell.

[0007] Preferably, a chute is fixedly connected to the upper surface of the bottom plate, a rack is movably connected inside the chute, the rack is meshed with the second gear, a baffle is movably connected inside the chute, a limiting component is fixedly connected to the upper surface of the bottom plate, the surface of the limiting component is movably connected to the inside of the baffle, and an adjusting structure is arranged on the upper surface of the bottom plate.

[0008] Preferably, an articulated shaft is threadedly connected to the inside of the upper end of the first fixing frame. The surface of the articulated shaft is rotatably connected to a second fixing frame. Retaining structures are provided inside both the first fixing frame and the second fixing frame. First fixing nails are movably connected to the surfaces of the first fixing frame and the second fixing frame.

[0009] Preferably, the driving structure includes a first bevel gear fixedly connected to the surface of the first rotating shaft. A second rotating shaft is rotatably connected to the inside of the fixed housing. A second bevel gear is fixedly connected to the rear of the second rotating shaft. The second bevel gear meshes with the first bevel gear. An eccentric drive disk is fixedly connected to the front section of the second rotating shaft.

[0010] Preferably, the adjusting structure includes a fixed block fixedly connected to the upper surface of the bottom plate. A first threaded adjusting rod is rotatably connected to the inside of the left fixed block. The surface of the first threaded adjusting rod is threadedly connected to the inside of the front baffle. A second threaded adjusting rod is rotatably connected to the inside of the right fixed block. The surface of the second threaded adjusting rod is threadedly connected to the inside of the rear baffle.

[0011] Preferably, the retaining structure includes hanging columns threadedly connected to the inside of the first fixing frame and the second fixing frame. A connecting strip is detachably installed inside the hanging columns. Retaining plates are fixedly installed on the surfaces of the hanging columns.

[0012] Preferably, a limiting column is fixedly connected to the inner surface of the fixed ear. One end side of the limiting column is flush with one end side of the first fixing frame.

[0013] Preferably, circular holes are formed in both the left and right parts of the bottom plate. Second fixing nails are movably connected to the inside of the circular holes.

[0014] The beneficial effects of the present invention are as follows: 1. By rotating the eccentric drive disk in the present invention, the rotation of the eccentric drive disk drives the second rotating shaft to rotate inside the fixed housing, and then drives the rotation of the second bevel gear. However, since the second bevel gear meshes with the first bevel gear, it drives the first rotating shaft to rotate inside the fixed housing. Thus, due to the meshing of the second gear and the first gear, it drives the rotating shaft to rotate inside the fixed ear, and then the retaining structure arranged above the rotating shaft is used for slope protection. This device only needs to rotate the eccentric drive disk to realize the change of the inclination angle of the first fixing frame, so as to meet the protection of different slopes. Therefore, it has strong practicability and simple operation.

[0015] 2. In the present invention, through the mutual meshing of the second gear and the rack, and since the rack slides inside the chute and the baffle also slides inside the chute, by adjusting the second threaded adjusting rod, the excessive backward movement of the rack is prevented, thereby protecting the second gear and the rack, preventing the second gear from suddenly receiving a rotational force due to the center of gravity shift of the retaining structure, and after the device is installed, preventing the retaining structure from rotating forward due to the landslide of the soil slope. The front baffle plays a resistance role on the rack, thereby improving the stability of the slope protection.

[0016] 3. In the present invention, the second fixing frame is embedded inside the first fixing frame, and by inserting and rotating the hinge shaft, the second fixing frame and the first fixing frame become hinged. Then, a retaining structure is installed inside the first fixing frame and the second fixing frame, and the slope is protected by the retaining structure. Subsequently, the first fixing nails are driven into the soil slope inside both the first fixing frame and the second fixing frame. The second fixing frame can be connected in multiple groups to achieve the protection of different slope lengths. This device uses a quick-disassembly method to protect different slope lengths, and the second fixing frame and the first fixing frame form a hinged relationship, thereby accommodating the unevenness of the slope and increasing the practicality of the device.

Detailed implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 8 shown, the embodiment of the present invention provides a slope protection device for thermal pipeline construction in a complex environment, including a bottom plate 1. A fixed ear 2 is fixedly connected to the upper surface of the bottom plate 1. A rotating shaft 3 is rotatably connected inside the fixed ear 2. A first fixing frame 4 is fixedly connected to the surface of the rotating shaft 3. A first gear 5 is fixedly connected to the surface of the rotating shaft 3. A fixed shell 6 is fixedly connected to the upper surface of the bottom plate 1. A first rotating shaft 7 is rotatably connected inside the fixed shell 6. Second gears 8 are fixedly connected to both ends of the first rotating shaft 7. The second gears 8 are meshed with the first gear 5. A driving structure is arranged inside the fixed shell 6.

[0021] When the staff needs to protect the slope, the bottom plate 1 is installed at the bottom of the slope. By rotating the eccentric drive disc 19, the rotation of the eccentric drive disc 19 drives the second rotating shaft 17 to rotate inside the fixed shell 6, and then drives the rotation of the second bevel gear 18. However, since the second bevel gear 18 is meshed with the first bevel gear 16, the first rotating shaft 7 is driven to rotate inside the fixed shell 6. Then, since the second gear 8 is meshed with the first gear 5, the rotation of the first gear 5 is driven. Then, since the first gear 5 is fixedly connected to the surface of the rotating shaft 3, the rotating shaft 3 is driven to rotate inside the fixed ear 2. Then, since the first fixing frame 4 is fixedly connected to the surface of the rotating shaft 3, the angle of the retaining structure arranged inside the first fixing frame 4 is adjusted.

[0022] Among them, the upper surface of the bottom plate 1 is fixedly connected with a chute 9. A rack 10 is movably connected inside the chute 9. The rack 10 meshes with the second gear 8. A baffle 11 is movably connected inside the chute 9. The upper surface of the bottom plate 1 is fixedly connected with a limiting component 12. The surface of the limiting component 12 is movably connected with the inside of the baffle 11. The upper surface of the bottom plate 1 is provided with an adjusting structure.

[0023] As the second gear 8 rotates, since the second gear 8 meshes with the rack 10, and the rack 10 slides inside the chute 9. However, due to the certain weight of the retaining structure, when the first fixing frame 4 rotates backward from the vertical state, due to the meshing of the first gear 5 and the second gear 8, and the meshing of the rack 10, the rack 10 is driven to move backward. At this time, the second threaded adjusting rod 22 can be adjusted to limit the backward movement of the rack 10. And after the protective device is installed, by adjusting the first threaded adjusting rod 21, the slope is prevented from tipping over.

[0024] Among them, the upper end inside of the first fixing frame 4 is threadedly connected with a hinge shaft 13. The surface of the hinge shaft 13 is rotatably connected with a second fixing frame 14. Retaining structures are arranged on the inner sides of the first fixing frame 4 and the second fixing frame 14. The surfaces of the first fixing frame 4 and the second fixing frame 14 are both movably connected with first fixing nails 15.

[0025] Due to the uncertainty of the slope, when the slope is relatively long, the second fixing frame 14 is embedded inside the first fixing frame 4, and the hinge shaft 13 is inserted into the junction of the second fixing frame 14 and the first fixing frame 4 and rotated. Since one end of the hinge shaft 13 is threadedly connected with one end of the first fixing frame 4, a hinge relationship is formed between the first fixing frame 4 and the second fixing frame 14. Before installing the second fixing frame 14, the hanging post 23 is threadedly rotated into the inside of the second fixing frame 14. Secondly, the retaining plate 25 is installed, then the connecting strip 24 is installed. Subsequently, the second fixing frame 14, the hanging post 23 and the retaining plate 25 on the other side of the connecting strip 24 are installed. And multiple second fixing frames 14 are installed according to the slope length. The hinge shaft 13 is also threadedly connected with the upper end of the second fixing frame 14.

[0026] Among them, the driving structure includes a first bevel gear 16 fixedly connected to the surface of the first rotating shaft 7. A second rotating shaft 17 is rotatably connected inside the fixed shell 6. A second bevel gear 18 is fixedly connected to the rear part of the second rotating shaft 17. The second bevel gear 18 meshes with the first bevel gear 16. An eccentric driving disc 19 is fixedly connected to the front section of the second rotating shaft 17.

[0027] By rotating the eccentric driving disc 19, the second rotating shaft 17 is driven to rotate inside the fixed shell 6, and then the first bevel gear 16 is driven to rotate, thereby driving the first rotating shaft 7 rotatably connected inside the fixed shell 6 to rotate.

[0028] Among them, the adjusting structure includes a fixing block 20 fixedly connected to the upper surface of the bottom plate 1. A first threaded adjusting rod 21 is rotatably connected inside the left fixing block 20. The surface of the first threaded adjusting rod 21 is threadedly connected to the inside of the front baffle 11. A second threaded adjusting rod 22 is rotatably connected inside the right fixing block 20. The surface of the second threaded adjusting rod 22 is threadedly connected to the inside of the rear baffle 11.

[0029] By adjusting the fixing block 20, the position of the front baffle 11 inside the sliding groove 9 is changed to prevent the first fixing frame 4 from rotating forward around the rotating shaft 3. By rotating the second threaded adjusting rod 22, the position of the rear baffle 11 inside the sliding groove 9 is changed to prevent the first fixing frame 4 from moving backward along the rotating shaft 3.

[0030] Among them, the soil retaining structure includes hanging columns 23 threadedly connected inside the first fixing frame 4 and the second fixing frame 14. A connecting strip 24 is detachably installed inside the hanging columns 23. A soil retaining plate 25 is fixedly installed on the surface of the hanging columns 23.

[0031] By sequentially installing the hanging columns 23, the soil retaining plates 25, and the connecting strips 24, and then connecting the first fixing frame 4 and the second fixing frame 14, the rapid disassembly and installation of the soil retaining structure are realized. Moreover, the soil retaining plate 25 has a good water drainage effect. If there is a lot of groundwater in the slope, it is easy to be discharged.

[0032] Among them, a limiting column 26 is fixedly connected to the inner surface of the fixing ear 2. One end side of the limiting column 26 is flush with one end side of the first fixing frame 4.

[0033] The first fixing frame 4 is limited by the limiting column 26 to avoid the first fixing frame 4 rotating forward around the rotating shaft 3 and thus causing a collision with the fixing shell 6.

[0034] Among them, round holes 27 are opened on both the left and right sides of the bottom plate 1. A second fixing nail 28 is movably connected inside the round holes 27.

[0035] Through the design of the round holes 27, the second fixing nail 28 can be inserted into the round holes 27, and the fixed connection between the bottom of the slope and the bottom plate 1 is realized through the second fixing nail 28.

[0036] Working principle and usage process: When the staff needs to protect the slope, install the bottom plate 1 at the bottom of the slope. By rotating the eccentric drive disk 19, the rotation of the eccentric drive disk 19 drives the second rotating shaft 17 to rotate inside the fixed shell 6, and then drives the rotation of the second bevel gear 18. However, since the second bevel gear 18 meshes with the first bevel gear 16, it drives the first rotating shaft 7 to rotate inside the fixed shell 6. Then, since the second gear 8 meshes with the first gear 5, it drives the rotation of the first gear 5. Then, since the first gear 5 is fixedly connected to the surface of the rotating shaft 3, it drives the rotating shaft 3 to rotate inside the fixed ear 2. Then, since the first fixing frame 4 is fixedly connected to the surface of the rotating shaft 3, it drives the angle adjustment of the retaining structure arranged inside the first fixing frame 4.

[0037] With the rotation of the second gear 8, since the second gear 8 meshes with the rack 10 and the rack 10 slides inside the chute 9. However, since the retaining structure has a certain weight, when the first fixing frame 4 rotates backward from the vertical state, due to the meshing of the first gear 5 and the second gear 8 and the meshing of the rack 10, it drives the rack 10 to move backward. At this time, the second threaded adjustment rod 22 can be adjusted to limit the backward movement of the rack 10. And after the protective device is installed, by adjusting the first threaded adjustment rod 21, the slope can be prevented from tipping over.

[0038] Due to the uncertainty of the slope, when the slope is relatively long, insert the second fixing frame 14 into the first fixing frame 4 and insert and rotate the hinge shaft 13 at the junction of the second fixing frame 14 and the first fixing frame 4. Since one end of the hinge shaft 13 is threadedly connected to one end of the first fixing frame 4, a hinge relationship is formed between the first fixing frame 4 and the second fixing frame 14. Before installing the second fixing frame 14, threadedly rotate the hanging post 23 into the second fixing frame 14, then install the retaining plate 25, then install the connecting strip 24, and then install the second fixing frame 14, the hanging post 23 and the retaining plate 25 on the other side of the connecting strip 24. And install multiple second fixing frames 14 according to the slope length. The hinge shaft 13 is also threadedly connected to the upper end of the second fixing frame 14.

[0039] By rotating the eccentric drive disk 19, it drives the second rotating shaft 17 to rotate inside the fixed shell 6, and then drives the rotation of the first bevel gear 16, thereby driving the first rotating shaft 7 rotatably connected inside the fixed shell 6 to rotate.

[0040] By adjusting the fixed block 20, the position of the front baffle 11 inside the chute 9 can be changed to prevent the first fixing frame 4 from rotating forward with the rotating shaft 3 as the axis. By rotating the second threaded adjustment rod 22, the position of the rear baffle 11 inside the chute 9 can be changed to prevent the first fixing frame 4 from moving backward with the rotating shaft 3 as the axis.

[0041] By successively installing the hanging column 23, the retaining plate 25, and the connecting strip 24, and then connecting the first fixing frame 4 and the second fixing frame 14, the rapid disassembly and installation of the retaining structure can be achieved. Moreover, the retaining plate 25 has a good water drainage effect, and if there is a lot of groundwater in the slope, it is easy to be discharged.

[0042] The first fixing frame 4 is limited by the limiting column 26 to prevent the first fixing frame 4 from rotating forward around the rotating shaft 3, thus avoiding collision with the fixed shell 6.

[0043] Through the design of the round hole 27, the second fixing nail 28 can be inserted into the inside of the round hole 27, and the fixed connection between the bottom of the slope and the bottom plate 1 can be realized through the second fixing nail 28.
