Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a device for opening a foundation pit in building engineering. Background Technology

[0002] As is well known, foundation pit excavation equipment is a specialized piece of equipment used in building construction for excavating foundation pits. It mainly uses mechanical structures to break up, transport, and shape the soil for foundation pit excavation. It typically includes a power system, excavation mechanism, walking device, and control components. It can complete earthwork excavation, slope trimming, and other operations according to the design dimensions, depth, and geological conditions of the foundation pit. This equipment is widely used in foundation construction scenarios such as housing construction, municipal engineering, and transportation facilities. It can effectively improve the efficiency of foundation pit excavation and ensure that construction proceeds according to design specifications. It is an important piece of equipment for achieving mechanized operations in modern building foundation engineering.

[0003] The existing excavation equipment technology has the following problems: In the actual application of existing excavation equipment for pit excavation in construction, there are still certain shortcomings. The buckets of existing excavation equipment are mostly integrated designs. As the buckets of excavation equipment are constantly excavated for pits, the protruding shovel blocks at the front of the bucket will deform or even break over time, requiring the entire bucket to be replaced, resulting in a waste of resources. In addition, installation is troublesome and the practical performance is low. An existing patent (publication number: CN212248420U) discloses a pit excavation device for construction, including a cab and a base. The cab is mounted on the upper outer wall of the base, and an engine box is installed on the base at the rear of the cab. An excavating boom is installed on the base on the left side of the cab. During excavation, prolonged digging can cause the shovel to wear and deform due to collision. This utility model's pit excavation device uses a bucket with a T-shaped sliding rod and a sliding groove to facilitate the smooth sliding of the insert frame inside the bucket. The insert plate can be smoothly inserted into the insert frame through the plate groove inside the frame, combining and connecting the shovel plate and the bucket. Finally, it is fixed by corresponding fastening nuts and fastening holes. This allows the shovel plate to be easily disassembled and replaced when the shovel is damaged, avoiding the waste of resources caused by replacing the entire bucket.

[0004] To address the aforementioned issues, existing patents have provided solutions. However, during the excavation of foundation pits, especially when digging soil on the foundation, the soil contains not only mud and sand, but also large objects such as stones and debris. Due to the lack of a structure for pre-separating the soil and stones during the excavation process, the subsequent separation of soil and stones becomes more complicated, reducing the flexibility of pre-processing excavated materials during the excavation process.

[0005] Therefore, a device for excavating foundation pits in building engineering is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a foundation pit opening device for construction engineering, which can solve the problem that the existing structure lacks a preliminary separation of soil and rocks during the foundation pit opening process, thus increasing the complexity of subsequent soil and rock separation operations and reducing the flexibility of material pretreatment during foundation pit opening.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a foundation pit excavation device for construction engineering, comprising an engineering vehicle, an adjustment mechanism, and an excavation mechanism. The adjustment mechanism is located on the rear side of the top of the engineering vehicle, and the excavation mechanism is located on the rear side of the adjustment mechanism. The excavation mechanism includes a conveyor track, a conveyor belt, a soil screen, and an excavating shovel. The conveyor track is located inside the adjustment mechanism, the conveyor belt is located inside the conveyor track, the soil screen is snapped onto the inner side of the conveyor belt, and the excavating shovel is fixedly connected to the surface of the conveyor belt.

[0008] Preferably, the adjustment mechanism includes a guide component and a separation component, the guide component being located on the rear side of the top of the engineering vehicle, and the separation component being located on the rear side of the guide component.

[0009] Preferably, the guiding assembly includes a robotic arm body, an adjusting motor, and an adjusting block. The robotic arm body is fixedly connected to the rear side of the top of the engineering vehicle. The adjusting motor is located on the side of the robotic arm body away from the engineering vehicle. The adjusting block is rotatably connected to the inner side of the robotic arm body on the side away from the engineering vehicle. The side of the adjusting block closest to the adjusting motor is fixedly connected to the output end of the adjusting motor.

[0010] Preferably, the separation assembly includes a positioning frame, an electric rotating rod assembly, a separation baffle, and a blocking plate. The positioning frame is fixedly connected to the surface of the adjusting block. The electric rotating rod assembly is located inside the positioning frame. The separation baffle is fixedly connected to the inside of the positioning frame. The blocking plate is fixedly connected to the side of the separation baffle away from the engineering vehicle. The surface of the electric rotating rod assembly is fixedly connected to the inner side of the conveyor belt. The surface of the blocking plate contacts the front side of the inner side of the conveyor belt.

[0011] Preferably, the joints of the robotic arm body are equipped with an assist motor, and the surface of the assist motor is equipped with a protective shell.

[0012] Preferably, a guide arc plate is fixedly connected to the inner side of the separation baffle, and the surface of the guide arc plate is provided with guide texture.

[0013] Preferably, a centralized interception plate is fixedly connected to both sides of the excavating shovel, and the centralized interception plate is inclined.

[0014] Preferably, a soil loosening shovel is fixedly connected to the surface of the conveyor belt, and the soil loosening shovel is designed in a V-shape.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This application, by setting up an opening mechanism, allows the conveyor belt to cooperate with the conveyor plate belt, the soil screen, and the digging shovel. Driven by the adjustment mechanism, the conveyor belt can drive the conveyor plate belt to move in a cycle. As the conveyor plate belt drives the digging shovel, the continuous cycle continuously feeds the soil in contact with it onto the soil screen. Guided by the digging shovel, the soil is transported to the separation point of the adjustment mechanism. Through the continuous transport of soil by the soil screen, most of the soil can fall through the mesh of the screen's own mesh structure into the separation point of the adjustment mechanism. Stones and debris that cannot pass through the mesh are transported to the end of the conveyor belt and the conveyor plate belt's cycle, achieving preliminary separation of soil, sand, dust, stones, and debris in the soil. 2. This application, by setting up an adjustment mechanism, allows the guiding component to cooperate with the separation component. The engineering vehicle is an intelligent tracked mobile structure remotely controlled by an intelligent control system, which can automatically move the entire structure of the adjustment mechanism to the required location for excavation. Through its built-in intelligent control system, the entire structure of the adjustment mechanism is automatically controlled. The robotic arm can drive the adjustment motor and adjustment block to move the separation component to the required location for excavation. The adjustment motor drives the axial rotation of the adjustment block to adaptively adjust the tilt angle of the separation component, allowing the positioning frame to move the entire structure of the excavation mechanism to the required location for excavation. The electric rotating rod group drives the conveyor track to move cyclically, enabling the excavation mechanism to excavate the soil in the excavation pit. The baffle can block the mesh of the screen on the inner front side of the conveyor belt, allowing the screen to move to the separation baffle away from the baffle, allowing soil and sand to fall into the separation baffle from the mesh. The separation baffle then transports the soil and sand to both sides, ultimately achieving preliminary separation of soil, sand, stones, and debris in the soil. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: A foundation pit excavation device for construction engineering includes an engineering vehicle 1, an adjustment mechanism 2, and an excavation mechanism 3. The adjustment mechanism 2 is located on the rear side of the top of the engineering vehicle 1, and the excavation mechanism 3 is located on the rear side of the adjustment mechanism 2. The excavation mechanism 3 includes a conveyor track 31, a conveyor belt 32, a soil screen 33, and an excavator 34. The conveyor track 31 is located inside the adjustment mechanism 2, the conveyor belt 32 is located inside the conveyor track 31, the soil screen 33 is snapped into the inner side of the conveyor belt 32, and the excavator 34 is fixedly connected to the surface of the conveyor belt 32.

[0020] In this embodiment: by setting the opening mechanism 3, the conveyor belt 31 can cooperate with the conveyor belt 32, the soil screen 33 and the digging shovel 34. With the adjustment mechanism 2, the conveyor belt 31 can drive the conveyor belt 32 to move in a cycle. Thus, when the conveyor belt 32 drives the digging shovel 34 to move, the soil in contact with it is continuously shoveled onto the soil screen 33 by the continuous cycle. Under the guidance of the digging shovel 34, the shoveled soil is transported to the separation point of the adjustment mechanism 2. After the continuous transport of soil by the soil screen 33, most of the soil can fall into the separation point of the adjustment mechanism 2 through the mesh structure of the soil screen 33 itself, while stones and debris that cannot pass through the mesh are transported to the end of the cycle of the conveyor belt 31 and the conveyor belt 32, realizing the preliminary separation of soil, sand and dust and stones and debris in the soil.

[0021] Specifically, such as Figure 2 As shown, the adjustment mechanism 2 includes a guide component 21 and a separation component 22. The guide component 21 is located on the rear side of the top of the engineering vehicle 1, and the separation component 22 is located on the rear side of the guide component 21.

[0022] Specifically, such as Figure 3 As shown, the guide assembly 21 includes a robotic arm body 211, an adjusting motor 212, and an adjusting rotating block 213. The robotic arm body 211 is fixedly connected to the rear side of the top of the engineering vehicle 1. The adjusting motor 212 is located on the side of the robotic arm body 211 away from the engineering vehicle 1. The adjusting rotating block 213 is rotatably connected to the inner side of the side of the robotic arm body 211 away from the engineering vehicle 1. The side of the adjusting rotating block 213 close to the adjusting motor 212 is fixedly connected to the output end of the adjusting motor 212.

[0023] Specifically, such as Figure 4 As shown, the separation assembly 22 includes a positioning frame 221, an electric rotating rod assembly 222, a separation baffle 223, and a blocking plate 224. The positioning frame 221 is fixedly connected to the surface of the adjusting block 213. The electric rotating rod assembly 222 is located inside the positioning frame 221. The separation baffle 223 is fixedly connected to the inside of the positioning frame 221. The blocking plate 224 is fixedly connected to the side of the separation baffle 223 away from the engineering vehicle 1. The surface of the electric rotating rod assembly 222 is fixedly connected to the inside of the conveyor belt 31. The surface of the blocking plate 224 contacts the front side of the inside of the conveyor belt 32.

[0024] In this embodiment: by setting the adjustment mechanism 2, the guiding component 21 can cooperate with the separation component 22. The engineering vehicle 1 is an intelligent tracked mobile structure remotely controlled by an intelligent control system in the prior art. It can drive the entire structure of the adjustment mechanism 2 to automatically move to the required position for opening the foundation pit. Through its own intelligent control system, the entire structure of the adjustment mechanism 2 is automatically controlled. The robotic arm body 211 can drive the adjustment motor 212 and the adjustment rotating block 213 to move the separation component 22 to the required position for opening the foundation pit. The adjustment motor 212 drives the axial rotation of the adjustment rotating block 213, which can adjust the tilt angle of the separation component 22 appropriately. The positioning frame 221 can move the entire structure of the opening mechanism 3 to the desired location of the foundation pit. The electric rotating rod assembly 222 drives the conveyor belt 31 to move cyclically, enabling the opening mechanism 3 to excavate the foundation pit soil. The blocking plate 224 can block the mesh of the screen 33 on the inner front side of the conveyor belt 32, allowing the screen 33 to move away from the blocking plate 224 to the separation baffle 223, allowing soil and dust to fall into the separation baffle 223 from the mesh. The separation baffle 223 then transports the soil and dust to both sides, ultimately achieving the preliminary separation of soil, dust, stones, and debris in the soil.

[0025] Specifically, such as Figure 3As shown, the joint of the robotic arm body 211 is equipped with an assist motor 214, and the surface of the assist motor 214 is equipped with a protective shell.

[0026] Specifically, such as Figure 4 As shown, a guide arc plate 225 is fixedly connected to the inner side of the separation baffle 223, and the surface of the guide arc plate 225 is provided with guide texture.

[0027] In this embodiment: by setting up an assist motor 214 and a guide arc plate 225, the assist motor 214 can cooperate with the robotic arm body 211. The assist motor 214 provides auxiliary transmission to the joints of the robotic arm body 211, which can further increase the accuracy of the robotic arm body 211 during operation. In addition, the protective shell on the surface of the assist motor 214 can protect the assist motor 214 and improve its service life. The guide arc plate 225 can cooperate with the separation baffle 223. The guide arc plate 225 is an arc-shaped guiding structure. Through the guiding texture on the surface and the arc structure design, the mud and sand falling into the separation baffle 223 can be further guided to both sides.

[0028] Specifically, such as Figure 5 As shown, a centralized interception plate 35 is fixedly connected to both sides of the excavator shovel 34, and the centralized interception plate 35 is set in an inclined shape.

[0029] Specifically, such as Figure 5 As shown, a loosening shovel plate 36 is fixedly connected to the surface of the conveyor belt 31, and the loosening shovel plate 36 is designed in a V-shape.

[0030] In this embodiment: by setting a centralized interception plate 35 and a loosening shovel plate 36, the centralized interception plate 35 can cooperate with the digging shovel 34. The centralized interception plate 35 can use its own inclined structure to assist in guiding and limiting the soil shoveled into the digging shovel 34, further increasing the stability of the digging shovel 34 when transporting soil. The loosening shovel plate 36 can cooperate with the conveyor belt 31. When the loosening shovel plate 36 comes into contact with the soil that is in contact with the conveyor belt 31, it can use its own V-shaped design to assist in shoveling the soil, thereby loosening the soil that is about to come into contact with the digging shovel 34 and improving the efficiency of the digging shovel 34 in digging soil.

[0031] Working principle: First, the engineering vehicle 1 drives the adjustment mechanism 2 and the excavation mechanism 3 as a whole structure, moving to the desired location for excavation according to a preset program via a remotely controlled intelligent control system. Then, the robotic arm 211 drives the adjustment motor 212 and the adjustment block 213 to the soil at the desired excavation location. The adjustment motor 212 then drives the adjustment block 213 to rotate, adjusting the tilt angle of the positioning frame 221 to a suitable angle for excavation. Finally, the electric rotating rod assembly 222 drives the conveyor belt 31 to move cyclically. The conveyor belt 31 then drives the conveyor plate belt 32 to move the soil screen 33 and the excavating shovel 34 together. As the excavator moves step by step, the excavator shovel 34 will then deliver soil to the soil screen 33 upon contact with the soil. The soil screen 33 will then move along the baffle plate 224 toward the separation baffle plate 223. As it moves away from the baffle plate 224 and onto the separation baffle plate 223, the soil and dust will gradually fall into the separation baffle plate 223 due to the vibration generated by the movement of the soil screen 33. The soil that falls into the separation baffle plate 223 will gradually move to both sides with the vibration. The remaining stones and debris in the soil will continue to move with the excavator shovel 34 and the soil screen 33 to the end of the cyclical movement of the conveyor belt 31 and the conveyor plate belt 32 and fall down until the excavation of the foundation pit is completed.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
