Description

A construction device and method for a foundation cap of a power transmission line. Technical Field

[0001] This invention relates to the field of power facilities, specifically to a construction device and method for a foundation pier of a transmission line. Background Technology

[0002] With the rapid development of power construction in my country, more and more power transmission lines need to pass through mountainous or hilly areas. A significant characteristic of these areas is the widespread distribution of rock foundations. Therefore, selecting the appropriate foundation type is crucial for constructing environmentally friendly transmission lines. Tower foundations, as an important component of transmission line engineering, account for a large proportion of the overall cost, construction period, and labor consumption. Therefore, optimizing and innovating the foundation design of transmission lines in mountainous areas is of great significance. In mountainous or hilly areas with thick soil layers and a thick overburden layer above the rock, the connection frame between the tower and the foundation is close to the soil. Due to limitations in corrosion and rust prevention, its applicability is restricted, and it is prone to corrosion in long-term high-humidity environments, affecting the safety of the tower. For those skilled in the art, how to effectively prevent corrosion of communication tower connection frames is a technical problem that needs to be solved.

[0003] Chinese patent application CN114457836A discloses an embedded truss foundation anchor for transmission lines, comprising a precast reinforced concrete support and a precast concrete foundation. The precast reinforced concrete support is assembled onto the precast concrete foundation, and the precast concrete foundation is fixed to the rock stratum by anchor bolts. The reinforced concrete support includes an internal steel reinforcement skeleton and an outer concrete anti-rust layer. The precast reinforced concrete support is used to fix and connect the transmission tower.

[0004] While the above solution can prevent corrosion of the communication tower connecting frame, during construction, the tower needs to be pre-buried in the soil, which requires digging corresponding placement pits for the foundation. Most of the placement pits are dug manually, and the soil at the excavation site is mostly piled up around the perimeter, making it impossible to pour all of it into the pit at once during backfilling, which increases the workload. If a traditional chain grooving machine is used to groove, only strip-shaped grooves can be opened, while the placement grooves used to set the foundation are quadrilateral recesses, which cannot be achieved by using a chain grooving machine alone. Summary of the Invention

[0005] To address the aforementioned issues, a construction device and method for power transmission line foundation piers are provided. A chain-type trenching machine is started, and a probe plate is retracted by a pushing device. The chain-type trenching machine creates strip-shaped trenches on the ground surface. The soil excavated by the chain-type trenching machine is collected by a discharge and collection device. The pushing device pushes the probe plate out. The chain-type trenching machine continues trenching along one side of the strip-shaped trench. The probe plate positioned on one side of the chain-type trenching machine ensures that soil does not fall into the strip-shaped trench during trenching. When the probe plate contacts the bottom of the strip-shaped trench, a pressure monitoring device detects the pressure on the probe plate. When the pressure value detected by the pressure monitoring device exceeds a pre-set pressure value, the pushing device retracts the probe plate, ensuring that the probe plate does not obstruct the normal trenching operation of the chain-type trenching machine. This allows the device to automatically complete the excavation of the foundation pier placement trench.

[0011] Preferably, the guiding device includes a guide shell, a first slide, and a third pressure sensor; the first slide is fixedly mounted on the side wall of the chain grooving machine along the length of the chain grooving machine; the guide shell is fixedly mounted on the first slide, and the guide shell and the detection plate cover the lower part of the chain grooving machine; the third pressure sensor is located at the end of the guide shell.

The chain grooving machine continues to create grooves along one side of the strip-shaped groove. The detection plate on one side of the chain grooving machine ensures that soil does not fall into the strip-shaped groove during grooving. When the detection plate contacts the bottom of the strip-shaped groove, the pressure monitoring device detects the pressure on the detection plate. When the pressure value detected by the pressure monitoring device exceeds a preset pressure value, the pushing device retracts the detection plate, ensuring that the detection plate does not obstruct the normal grooving operation of the chain grooving machine. This allows the device to automatically complete the excavation of the foundation placement groove. Attached Figure Description

Detailed Implementation

[0034] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0035] Referring to Figures 1 and 2: A construction device for a transmission line foundation abutment includes a housing 1 and an excavating device 2. The excavating device 2 includes a chain trencher 21, a detection plate 22, a pressure monitoring device 23, a pushing device 24, and a material discharge and collection device 25. The chain trencher 21 is rotatably disposed inside the housing 1 and can excavate surface soil. The detection plate 22 is slidably disposed on one side of the chain trencher 21 along its length and can limit soil slippage at the end of the chain trencher 21. The pressure monitoring device 23 is disposed at the end of the detection plate 22 and can monitor the pressure value when the detection plate 22 contacts the soil. The pushing device 24 is disposed on the side of the pressure monitoring device 23 away from the detection plate 22 and can drive the detection plate 22 to slide along the length of the chain trencher 21. The material discharge and collection device 25 is disposed below the chain trencher 21 and can collect the soil excavated by the chain trencher 21.

[0036] The lower part of the outer casing 1 is equipped with a vehicle body, which can move independently. When the vehicle body moves, it moves the outer casing 1 along with it. During excavation, since the chain trencher 21 can only dig one trench at a time, if a square groove is to be dug, the chain trencher 21 needs to dig repeatedly. When starting the first trench, the chain trencher 21 starts, and the probe plate 22 is driven back by the pusher 24. The chain trencher 21 opens a strip-shaped trench on the ground surface. At this time, the probe plate 22 is not in contact with the soil. The soil excavated by the chain trencher 21 is collected by the discharge collection device 25. The pusher 24 pushes the probe plate 22 out. The chain trencher 21 continues to open along the length of the strip-shaped trench on one side. Since the probe plate 22 is set on one side of the chain trencher 21, the probe plate 22 can prevent the soil from slipping into the already dug groove on one side when the chain trencher 21 is excavating. Inside the trench, when the probe plate 22 contacts the bottom of the strip trench, the pressure monitoring device 23 detects the pressure on the probe plate 22. If the pressure monitoring device 23 is not installed, the probe plate 22 will block the bottom of the trench when the chain trenching machine 21 is digging, making it impossible for the chain trenching machine 21 to dig normally. However, with the pressure monitoring device 23 installed, as the pressure of the probe plate 22 in contact with the soil increases, the pressure monitoring device 23 can react accordingly by pushing the device 24. When the pressure value monitored by the pressure monitoring device 23 is greater than the preset pressure value, the pushing device 24 drives the probe plate 22 to retract, reducing the pressure of the probe plate 22 on the soil. This prevents the probe plate 22 from obstructing the chain trenching machine 21 from digging normally, allowing the device to automatically complete the excavation of the foundation placement trench.

[0037] Referring to Figures 2 and 8: The pressure monitoring device 23 includes an extension rod 231, a push plate 232, a spring 233, and a first pressure sensor 234; the extension rod 231 is fixedly disposed at the end of the probe plate 22 along the length direction of the probe plate 22; the push plate 232 is disposed on the side of the probe plate 22 where the extension rod 231 is disposed, the extension rod 231 passes through the push plate 232, and the extension rod 231 slides in cooperation with the push plate 232; there is a gap between the probe plate 22 and the push plate 232, and the spring 233 is disposed in the gap along the axis of the extension rod 231; the first pressure sensor 234 is fixedly disposed on the side of the push plate 232 close to the probe plate 22, and the two ends of the spring 233 are fixedly connected to the first pressure sensor 234 and the probe plate 22 respectively.

[0038] When the chain trencher 21 excavates the soil, the detection plate 22 located on one side of the chain trencher 21 moves along with it. When the chain trencher 21 excavates to the bottom of the trench, the end of the detection plate 22 will abut against the bottom of the trench. This will affect the normal excavation of the chain trencher 21. After the detection plate 22 contacts the soil, it slides relative to the chain trencher 21, causing the extension rod 231 to move along with it. The extension rod 231 slides relative to the push plate 232, and the gap between the detection plate 22 and the push plate 232 gradually decreases. The spring 233 inside the gap is compressed, and the reaction force generated by the spring 233 will press the first pressure sensor 234. The first pressure sensor 234 can then detect the pressure value. When the pressure value is greater than the preset value, the push device 24 will be activated. The push device 24 will drive the push plate 232 to move away from the detection plate 22. In this way, the pressure of the spring 233 will gradually decrease, and the resistance of the detection plate 22 to the bottom of the soil will also decrease. It is worth noting that the pressure of the first pressure sensor 234 needs to always maintain a monitoring value. This means that the detection plate 22 is always in contact with the soil, ensuring that the chain trenching machine 21 can trench normally while ensuring that the soil does not slip.

[0039] Referring to Figures 2 and 7: the pushing device 24 includes a first rotary driver 241, a lead screw 242, and a fixed seat 243; the lead screw 242 is disposed along the length of the probe plate 22 on the side of the pushing plate 232 away from the probe plate 22, and the end of the lead screw 242 near the pushing plate 232 is rotatably engaged with the pushing plate 232; the first rotary driver 241 is disposed on the side of the lead screw 242 away from the pushing plate 232, and the output end of the first rotary driver 241 is fixedly connected to the end of the lead screw 242 away from the pushing plate 232; the fixed seat 243 is disposed on the side of the pushing plate 232 away from the probe plate 22, the lead screw 242 passes through the fixed seat 243, and the lead screw 242 is threadedly engaged with the fixed seat 243.

[0040] When the pressure monitoring device 23 detects that the pressure of the probe plate 22 is increasing and exceeds the preset value, the first rotary driver 241 is started. The first rotary driver 241 drives the push plate 232 to move closer to the fixed seat 243 through the lead screw 242. At this time, the pressure of the spring 233 between the push plate 232 and the probe plate 22 gradually decreases, and the value detected by the first pressure sensor 234 will also gradually decrease. When the value detected by the first pressure sensor 234 is less than a certain value, the first rotary driver 241 stops running.

[0041] Referring to Figures 2, 6, and 7: the pushing device 24 further includes a slider 244, a slide rail 245, a trigger block 246, and a second pressure sensor; the slider 244 is fixedly disposed at the bottom of the first rotary driver 241; the slide rail 245 is disposed at the bottom of the slider 244 along the length direction of the probe plate 22, and the slider 244 slides in cooperation with the slide rail 245; the trigger block 246 is fixedly disposed on the slide rail 245 on the side of the slider 244 near the probe plate 22; the second pressure sensor is fixedly disposed on the trigger block, and the slider 244 can trigger the second pressure sensor; a controller is disposed on one side of the second pressure sensor, and the second pressure sensor controls the operation of the first rotary driver 241 through the controller.

[0042] After the first rotary drive 241 adjusts the position of the probe plate 22 via the lead screw 242, the probe plate 22 needs to be reset when it is no longer in use. This is because the spatial state of the chain grooving machine 21 will be different in different grooving needs. Thus, the previously used position of the probe plate 22 may not be able to effectively block one side of the chain grooving machine 21. During reset, the first rotary driver 241 drives the push plate 232 to move towards the probe plate 22 via the lead screw 242. Since the length of the lead screw 242 is fixed, the first rotary driver 241 itself will be displaced. Thus, the slider 244 and the slide rail 245 located at the lower part of the first rotary driver 241 slide relative to each other. When the slider 244 contacts the trigger block 246, the second pressure sensor located on the trigger block 246 will be pressed by the slider 244. The second pressure sensor detects the pressure and then controls the first rotary driver 241 to stop running through the controller. At this time, the probe plate 22 is in the initial position, that is, at this time when grooving, the end of the probe plate 22 that is closer to the soil is closer than the end of the chain grooving machine 21 that is closer to the soil.

[0043] Referring to Figures 2 and 3: the discharge collection device 25 includes a guide device 251, an inclined plate 252, and a collection box 253; the guide device 251 is located below the chain grooving machine 21, and the guide device 251 can discharge the soil excavated by the chain grooving machine 21; the inclined plate 252 is hinged to one side of the guide device 251; the collection box 253 is located on the side of the inclined plate 252 away from the guide device 251, and the collection box 253 is hinged to the inclined plate 252.

[0044] After the chain grooving machine 21 excavates the soil, it is guided by the guide device 251 and poured onto the inclined plate 252. Under the guidance of the inclined plate 252, the excavated soil slides into the collection box 253, thus completing the collection of the excavated soil. After the support platform is set up, the soil in the collection box 253 is poured into the groove.

[0045] Referring to Figures 3-5: The guiding device 251 includes a guide shell 2511, a first slide 2512, and a third pressure sensor; the first slide 2512 is fixedly mounted on the side wall of the chain grooving machine 21 along the length direction of the chain grooving machine 21; the guide shell 2511 is fixedly mounted on the first slide 2512, and the guide shell 2511 and the detection plate 22 enclose the lower part of the chain grooving machine 21; the third pressure sensor is located at the end of the guide shell 2511.

[0046] Because the tilt angle of the chain grooving machine 21 changes during operation, the soil needs to be guided into the collection box 253 during the excavation process. At this time, the first slide 2512 drives the guide shell 2511 to move towards the soil. When the third pressure sensor on the guide shell 2511 comes into contact with the soil, the third pressure sensor sends a signal to the controller, and the controller controls the first slide 2512 to stop running. When the chain grooving machine 21 excavates, it carries the soil out from the side wall of the groove. Then, the chain grooving machine 21 guides the soil out from the guide shell 2511. This is because the guide shell 2511 holds the chain grooving machine 21 tightly, ensuring that the soil will not slip. Guided by the guide shell 2511, the soil carried out by the chain grooving machine 21 slides into the collection box 253 through the inclined plate 252.

[0047] Referring to Figures 10 and 11: the excavation device 2 also includes a guide groove 221 and a guide block 222; the guide groove 221 is opened along the length direction of the chain grooving machine 21 on the side wall of the chain grooving machine 21; the guide block 222 is fixedly installed on the side wall of the detection plate 22 near the chain grooving machine 21, and the guide block 222 is slidably engaged with the guide groove 221.

[0048] By setting guide groove 221 and guide block 222, the detection plate 22 can slide stably on one side of the chain grooving machine 21.

[0049] Referring to Figures 1-3 and 5: the excavation device 2 also includes an adjustment device 26, which includes a second slide 261 and a second rotary driver 262; the second rotary driver 262 is fixedly mounted on the side wall of the chain grooving machine 21 and can drive the chain grooving machine 21 to rotate as a whole; the second slide 261 is vertically mounted on one side of the second rotary driver 262 and can drive the chain grooving machine 21 to move in the vertical direction.

[0050] When the second rotary driver 262 is started, it can drive the chain grooving machine 21 to rotate, and the second slide table 261 can drive the second rotary driver 262 to move in the vertical direction.

[0051] Referring to Figure 3: the discharge collection device 25 also includes wheels 2531; the wheels 2531 are fixedly installed at the bottom of the collection box 253.

[0052] When the chain grooving machine 21 grooves the soil, different spatial states of the chain grooving machine 21, that is, different tilting postures of the chain grooving machine 21, will cause the collection box 253 to move. By setting wheels 2531 at the bottom of the collection box 253, the collection box 253 can move better.

[0053] Referring to Figures 1-11: This invention also relates to a method for constructing a foundation cap for a power transmission line, the specific steps of which are as follows:

[0054] S1. The chain grooving machine 21 starts, the detection plate 22 is driven to retract by the pushing device 24, the chain grooving machine 21 opens strip-shaped grooves on the ground surface, and the soil excavated by the chain grooving machine 21 is collected by the discharge collection device 25.

[0055] S2. The pushing device 24 pushes out the probe plate 22, and the chain grooving machine 21 continues to open along the length of the strip groove on one side. When the probe plate 22 contacts the bottom of the strip groove, the pressure monitoring device 23 monitors the pressure on the probe plate 22.

[0056] S3. When the pressure value monitored by the pressure monitoring device 23 is greater than the preset pressure value, the push device 24 drives the probe plate 22 to retract.

[0057] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
