Description

Technical Field

[0001] The invention belongs to the field of reservoir box culvert construction equipment, and in particular relates to a reservoir box culvert foundation excavation construction equipment. Background Art

[0002] During the construction of a pumped-storage reservoir, it is necessary to lay a box culvert. For example, a box culvert for drainage will be laid at the bottom of the reservoir slag dump. Before laying the box culvert, foundation excavation is required to form a trench first. The box culvert is cast in sections in the trench, and then backfilled. The two side walls of the trench form inclined slopes, which are mainly to prevent soil collapse from causing harm to workers and the box culvert being cast in place, and to facilitate the entry of workers and building materials into the trench when the box culvert is cast in place. The existing equipment for excavating trenches is an excavator. The excavator first excavates a trench with a square cross-section along the forward direction of the trench, which is relatively efficient. However, when excavating the slopes on the two vertical side walls of the trench, the excavator bucket cannot continuously dig along a slope, and repeated subtle adjustments and point-by-point digging are required, which is very inefficient, resulting in low overall trench excavation efficiency. Summary of the Invention

[0003] The object of the present invention is to provide a reservoir box culvert foundation excavation construction device. The present invention has the advantage of improving the overall trench excavation efficiency.

[0004] The technical solution of the present invention is: a reservoir box culvert foundation excavation construction equipment, including a base plate, pressure plates are provided on both sides of the base plate, a driving mechanism is provided on the pressure plate, a through hole is provided on the front of the pressure plate, a plate chain conveyor is provided in the through hole, the frame of the conveyor is fixed to the pressure plate, a scraping plate is provided on the plate chain of the conveyor, the outer end of the scraping plate is wavy, and multiple scraping plates move to form a hook digging surface, which is on the inner side of the pressure plate.

[0005] In the aforementioned reservoir box culvert foundation excavation construction equipment, the driving mechanism includes an inclined frame plate, the upper end of the frame plate is hinged to the inner side wall of the upper part of the pressure plate, a first oil cylinder is provided between the frame plate and the pressure plate, and the lower ends of the two frame plates are hinged together.

[0006] In the aforementioned reservoir box culvert foundation excavation construction equipment, the bottom of the base plate is provided with multiple concave areas, rollers are provided in the concave areas, and a first rotating shaft is provided on the rollers, and the two ends of the first rotating shaft respectively pass through the two side walls of the concave areas.

[0007] In the aforementioned reservoir box culvert foundation excavation construction equipment, a guide plate with its front end inclined inward is provided on the front side of the pressure plate.

[0011] In the aforementioned reservoir box culvert foundation excavation construction equipment, the chain plates provided with the scraping plates and the chain plates provided with the cutting plates are arranged at intervals.

[0012] Compared with the existing technology, the present invention cooperates with an excavator to perform foundation excavation. First, the excavator excavates a trench with a square cross-section. Then, the two vertical side walls of the trench are constructed. During construction, the pressure plate is driven to rotate outward by a cylinder. During the rotation of the pressure plate, two conveyors drive the scraping plate to rotate, scraping the soil upward to form a flat slope, which has high excavation efficiency. At the same time, the pressure plate is used to compact the slope, making it firm and less prone to collapse. The slope excavation angle can be smaller, and the excavation work volume is also smaller, further improving the excavation efficiency. Therefore, the present invention has the advantage of improving the overall excavation efficiency of the trench. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and examples, but they are not intended to limit the present invention.

[0021] Example. A reservoir box culvert foundation excavation construction equipment, such as Figure 1 As shown, it includes a base plate 1, with pressure plates 2 on both sides of the base plate 1, a driving mechanism on the pressure plate 2, a through hole 3 on the front of the pressure plate 2, a plate chain conveyor 4 in the through hole 3, the frame of the conveyor 4 is fixed to the pressure plate 2, and a scraping plate 5 is provided on the plate chain of the conveyor 4. The outer end of the scraping plate 5 (i.e., the soil scraping end) is wavy, and multiple scraping plates 5 move to form a hook digging surface, which is on the inner side of the pressure plate 2.

[0022] The driving mechanism includes an inclined skeleton plate 6, which is welded from multiple square steel pipes. The upper end of the skeleton plate 6 is hinged to the inner side wall of the upper part of the pressure plate 2. A plurality of side-by-side first oil cylinders 7 are provided between the skeleton plate 6 and the pressure plate 2, and the lower ends of the two skeleton plates 6 are hinged together.

[0023] The bottom of the base plate 1 is provided with a plurality of recessed areas 8, each of which is provided with rollers 9. A first rotating shaft 10 is provided on the rollers 9, and the ends of the first rotating shaft 10 pass through the two side walls of the recessed areas 8. The rollers 9 facilitate movement of the present invention. Placing the rollers 9 in the recessed areas 8 reduces the distance between the base plate 1 and the bottom surface of the trench, allowing for a greater excavation depth on the slope and improving the excavation effect.

[0024] The front side of the pressing plate 2 is provided with a guide plate 11 with its front end tilted inwards. The guide plate 11 is used for guiding the present invention when it moves forward.

[0025] The two skeleton plates 6 are hingedly connected by a second rotating shaft 12. A plurality of first connecting plates 17 are provided on the second rotating shaft 12. The first connecting plate 17 is fixed to the bottom of one of the skeleton plates 6. A second connecting plate 18 fixed to the other skeleton plate 6 is provided on one side of the first connecting plate 17. The second rotating shaft 12 passes through all the first connecting plates 17 and all the second connecting plates 18 in sequence. A plurality of bearings 13 are provided on the second rotating shaft 12. A second oil cylinder 14 fixed to the base plate 1 is provided below the bearing 13. The output end of the second oil cylinder 14 is connected to the bearing 13.

[0026] The inner side of the pressing plate 2 is provided with a vibration motor 15. The vibration motor 15 is used for further compacting the slope, and the vibration motor 15 is only turned on when the pressing plate 2 compacts the slope.

[0027] A part of the chain plates of the conveyor 4 is provided with a horizontal stripping plate 5 , and the remaining chain plates are provided with a plurality of vertical cutting plates 16 , and the height of the cutting plates 16 is greater than that of the stripping plate 5 .

[0028] The chain plates provided with the stripping plates 5 and the chain plates provided with the cutting plates 16 are arranged at intervals.

[0029] Working principle: After a trench with a square cross section is excavated by an excavator, the present invention is placed in the trench for secondary construction and is pulled along the trench by the excavator or other power vehicles.

[0030] The second oil cylinder 14 and the first oil cylinder 7 extend, driving the pressure plate 2 to flip outward through the skeleton plate 6. The conveyor 4 drives the scraping plate 5 and the cutting plate 16 to rotate. The cutting plate 16 loosens the soil and acts as a comb, removing any large rocks in the soil. The scraping plate 5 scrapes the loosened soil upward. When the second oil cylinder 14 and the first oil cylinder 7 are extended to their maximum position, a slope is formed. After the second oil cylinder 14 and the first oil cylinder 7 retract, the entire device moves forward a distance. The second oil cylinder 14 and the first oil cylinder 7 extend again, scraping out another slope. At the same time, the pressure plate 2 contacts and compacts the previously scraped slope. The vibration motor 15 further increases the compaction force. Because the outer end of the scraping plate 5 is wavy, the slope scraped out by the scraping plate 5 is wavy, which can be squeezed more tightly by the pressure plate 2.

[0031] In the process of continuous advancement, new slopes are constantly excavated, and the new slopes are compacted in the next process of advancement.
