Description

Technical Field

[0001] This invention belongs to the field of ground anchor pre-embedding construction technology in power engineering, and particularly relates to a trenching machine for burying grounding electrodes in power construction. Background Technology

[0002] With the rapid development of the social economy, the demand for electricity supply is increasing, making power construction tasks increasingly arduous. Along with the large number of power engineering projects, the use of construction machinery and equipment is becoming more widespread and frequent. To achieve "mechanization replacing manpower and intelligentization reducing manpower," reduce the labor intensity of workers, improve their working environment, and realize the construction goals of "intelligentization, mechanization, and standardization," coupled with the State Grid Corporation's increasingly stringent requirements for mechanization and intelligentization from all construction units, the company has decided to comprehensively carry out technological innovation projects from the inside out. The full application of mechanization is also the company's future development direction.

[0003] In power engineering, ground anchors are a crucial construction tool. By securing them, they ensure that transmission lines do not topple or collapse during extreme weather conditions such as strong winds, rain, and snow, while also protecting line equipment from external damage. The diagram shows the side view of an existing rectangular pit for burying steel plate ground anchors. Figure 1 As shown. This method of pre-burying ground anchors mainly involves manually excavating rectangular pits and walkways. This method is labor-intensive, has low construction efficiency, and poses a risk of collapse during construction.

[0004] Therefore, based on existing ground anchors and in accordance with existing construction techniques, the applicant has developed a construction machine for burying grounding electrodes in power construction, which is intended to be used in soft soil and ordinary soil areas to complete the trenching and pit excavation work for pre-burying ground anchors. Summary of the Invention

[0019] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] like Figures 1 to 10 As shown in the figure, this embodiment provides a trenching machine for laying grounding electrodes in power construction, including an upper chassis 1, a middle chassis 8, and a lower chassis 18 arranged sequentially. The upper chassis 1 is provided with a first working platform and a second working platform, and the first working platform and the second working platform are respectively provided with an anchor pit excavation mechanism and a walkway drilling mechanism.

[0022] The anchor pit excavation mechanism includes an excavator frame 10, which is installed on the first working platform via an excavation attitude adjustment device. The attitude adjustment of the excavator frame is achieved through the excavation attitude adjustment device. The excavator frame 10 is equipped with a slide rail, through which an excavation and soil removal device is slidably connected.

[0023] Specifically, one end of the excavator frame 10 is rotatably connected to the support frame on the first working platform, and the other end of the excavator frame 10 is connected to the first working platform via an excavation lifting cylinder 19, forming an excavation posture adjustment device. The extension and retraction of the excavation lifting cylinder 19 enables the rotation of the excavator frame 10, allowing it to switch between horizontal and vertical positions, facilitating long-distance transportation and on-site relocation.

[0024] In this embodiment, the excavation and soil removal device includes a soil removal cover 4, which is installed on a slide rail and connected to a position adjustment cylinder. One end of the soil removal cover 4 serves as the excavation end, which is equipped with a soil collection box 6. Two milling wheels 15 are located at the end of the soil collection box, and each milling wheel 15 is connected to a hydraulic motor drive device 16. The other end of the soil removal cover 4 serves as the discharge end. The soil collection box 6 is connected to the discharge end via a soil removal conveyor 5.

[0025] In this embodiment, the soil extraction conveyor is a chain conveyor, and the chain plates on the chain conveyor are scoops. During operation, the soil extraction conveyor 5 and the milling wheel 15 work synchronously. The chain plates and scoops rotate in a cycle, collecting loose soil through the scoops and dumping it outside the anchor trench. The eccentric scoops are hinged to the chain plates and reliably limited. After the collected soil is dumped, it returns to its original position by its own weight, effectively reducing the volume of the recovery device and achieving high soil recovery efficiency.

[0026] Meanwhile, a slewing device is also provided between the first working platform and the upper chassis 18 to enable the first working platform to rotate relative to the upper chassis 18. The slewing device mainly uses a slewing bearing mechanism to turn the anchor pit excavation mechanism, allowing it to turn to the side of the equipment to excavate the anchor trench.

[0027] The jacking drilling mechanism includes a drilling frame 11, which is mounted on a second working platform via a drilling attitude adjustment device. The attitude of the drilling frame 11 is adjusted via the drilling attitude adjustment device. A jacking drilling device 12 is provided on the drilling frame 11.

[0028] Specifically, one end of the drilling frame 11 is rotatably connected to the support frame on the second working platform, and the other end of the drilling frame 11 is connected to the second working platform through a drilling lifting cylinder 20, forming a drilling attitude adjustment device. A slewing device may or may not be installed between the second working platform and the upper chassis as needed.

[0029] The ground anchor ropes should be installed using a trenchless method to improve the load-bearing capacity of the buried anchors. Holes should be drilled at a 45° angle vertically into the ground anchor trench, and the anchor ropes should be placed into the trench through the access hole. Therefore, the access hole excavation and soil removal device 12 adopts a drill rod structure.

[0030] The 12-type drilling and soil removal device for the horse track hole is mainly composed of a main body, a power unit, a straightening device, and a spiral drill rod.

[0031] 1) Main body: mainly composed of frame, two double-acting hydraulic cylinders, plate chain, etc.

[0032] 2) Power section: The motor reducer is connected to the frame and outputs power torque.

[0033] 3) Straightening device: The straightening device is located at the bottom of the frame and assists the drill rod to prevent tilting.

[0034] 4) Spiral drill rod: The spiral drill rod has spiral blades around its perimeter. The drilled soil is carried out by the spiral blades, ensuring that it does not deviate or slip even when encountering solid objects. Spiral drill rods are 2 meters long each.

[0035] The main features of the borehole excavation and soil removal device are: the drill rod is clamped by a hydraulic cylinder, then the drill rod is rotated to drill into the soil, and after drilling to a certain depth, the drill rod is reversed to be removed, resulting in high drilling efficiency.

[0036] Furthermore, this embodiment also incorporates lateral and longitudinal translation devices on the chassis to increase the length of the anchor trench. Since the dual-wheel milling mechanism of the excavation and soil removal device can only create anchor trenches up to 1.5m long, it cannot fully meet the needs of anchor installation during construction. The lateral and longitudinal translation devices utilize the extension and retraction of hydraulic cylinders to adjust the lateral and longitudinal displacement of the upper chassis, effectively increasing the length of the anchor trench.

[0037] The specific settings of the lateral and longitudinal translation devices are as follows: The upper chassis 1 is laterally slidably mounted on the middle chassis 8, and a lateral translation cylinder 14 is provided between the two. One end of the lateral translation cylinder 14 is connected to the upper chassis 1, and the other end is connected to the middle chassis 8. The extension and retraction of the lateral translation cylinder 14 enables the excavation and soil removal device to move laterally, increasing the trench length.

[0038] The middle chassis 8 is longitudinally slidably mounted on the lower chassis, and a longitudinal translation cylinder 9 is provided between the two. One end of the longitudinal translation cylinder 9 is connected to the middle chassis 8, and the other end is connected to the lower chassis 18. By operating the slewing device, the excavation and soil removal device is rotated 90°, so that the excavation and soil removal device is on the side of the equipment. By operating the longitudinal translation cylinder 9, the longitudinal translation of the excavation and soil removal device can be moved longitudinally, increasing the trench length.

[0039] During operation, the excavator frame 10 is first rotated to the upright position, the vehicle body is moved to position the anchor pit, and the mobile excavation and soil removal device is operated to place the milling wheel on the ground along the slide rail. The milling wheel then drills and rotates. The soil removed from the earthmoving box is transported out of the pit using a soil removal conveyor, achieving simultaneous excavation and soil removal. During milling, the milling wheel and earthmoving box move synchronously downwards along the slide rail, gradually completing the excavation in the depth direction of the anchor pit. The milling wheel can move horizontally with the vehicle body to complete the excavation requirements in the length direction of the anchor pit.

[0040] In this embodiment, support leg cylinders 2 are provided around the upper chassis 1 to ensure the stability of the equipment during operation.

[0041] This embodiment is equipped with a self-propelled mechanism on the lower chassis 18, which is conducive to accurate positioning of the anchor pit and accurate placement of the ground anchor, and facilitates movement within the site and transfer between sites.

[0042] In this embodiment, the power system 3 is arranged on the upper chassis 1. The power system 3 is driven by a hydraulic system. The hydraulic system provides power to each cylinder, motor and rotary device. The hydraulic drive has good controllability, low impact and easy control of the driving speed.

[0043] In this embodiment, an operating system 17 is also provided on the upper chassis 1 to facilitate personnel operation.

[0044] In this embodiment, the anchor pit excavation mechanism and the walkway drilling mechanism are respectively arranged on both sides of the chassis. The two sets of devices work sequentially, which facilitates the adjustment of the vehicle's power and improves working capacity. The equipment's multi-functional integrated design realizes mechanized construction of anchor trench excavation operations.

[0045] This invention combines an anchor pit excavation mechanism and a walkway drilling mechanism to achieve the operation of anchor pit excavation and walkway excavation. It integrates the construction of anchor pit excavation, anchor placement, walkway excavation, backfilling of original soil, and anchor removal in ground anchor installation, solving the construction problems of high labor intensity and low work efficiency in traditional ground anchor installation, and improving the equipment technology level of ground anchor installation.

[0046] The application of this invention enables mechanized construction of ground anchor excavation, ensuring the ground anchor is stressed and reducing vegetation damage.
