Description

A type of excavation device Technical Field

[0001] This utility model relates to the technical field of municipal construction, and in particular to an excavation device. Background Technology

[0002] In the process of urban planning and construction, excavation is frequently required for laying underground pipelines and constructing roads or bridges, and the most commonly used device in this process is the excavator. As seen in existing technologies, many excavators, such as those with patent applications 201921994841.3, 202111480924.2, and 202121262953.7, are basically composed of a vehicle body, a hydraulic robotic arm, and a bucket. In use, they excavate the ground using the bucket. However, the following problems exist during use: when excavating in areas where existing buildings are being demolished, there may be embedded steel bars or other metal components remaining underground in the foundation. If the excavator bucket comes into contact with these steel bars or other metal components during excavation, it can easily damage the bucket, even causing the bucket teeth to break, reducing the bucket's lifespan and increasing equipment maintenance costs. Therefore, there is a need for an excavation device that can detect underground metal objects in advance. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides an excavation device that can detect underground metals. Workers can pre-process the underground metal parts based on their location and re-plan the excavation path to avoid them, minimizing the risk of collision between the excavator bucket and the metal parts, reducing the risk of bucket damage, reducing bucket wear, and increasing the bucket's service life. It is a convenient and highly practical excavation device.

[0004] This utility model discloses an excavation device, including an excavator with a body and a bucket; it also includes a moving mechanism and a metal detection mechanism. The moving mechanism is mounted on the body, and the metal detection mechanism is mounted on the moving mechanism. The moving mechanism is used to move the metal detection mechanism, which has the function of detecting metal objects. When excavating in the demolition area of ​​an existing building, the excavator is first moved to the area where excavation is needed. Then, the moving mechanism moves the metal detection mechanism to a position close to the ground. Simultaneously, the metal detection mechanism moves to detect underground steel bars and other embedded metal parts. Once a buried metal part is detected, the metal detection mechanism issues an alarm. Workers can then take precautions based on the location of the underground metal part, replan the excavation path to avoid it, and minimize the risk of collision between the excavator bucket and the metal part. This reduces the risk of bucket damage, reduces bucket wear, and increases the bucket's service life. It is convenient to use and highly practical.

[0005] Preferably, the metal detection mechanism includes a connecting rod and a metal detector. The connecting rod is mounted on a moving mechanism, and the metal detector is fixedly mounted on the connecting rod. When detecting underground metal objects, the moving mechanism causes the connecting rod to move the metal detector to a suitable detection position. After detection, the moving mechanism causes the connecting rod to move the metal detector to the front of the vehicle body, moving the connecting rod and the metal detector away from the area to be excavated, reducing the impact of the connecting rod and the metal detector on the bucket excavation operation and facilitating the movement of the connecting rod and the metal detector.

[0006] Preferably, the moving mechanism includes a lifting mechanism, slide rail A, slide rail B, slider A, slider B, two connecting plates, and a driving mechanism. Slide rail A and slide rail B are fixedly installed at the front and rear ends of the vehicle body, respectively. Slider A is slidably installed on slide rail A, and slider B is slidably installed on slide rail B. The two connecting plates are fixedly installed on slider A and slider B, respectively. The driving mechanism is installed on the vehicle body and slider B, and is used to drive slider B to move left and right. The lifting mechanism is installed on the left side of the two connecting plates and is located on the left side of the vehicle body. A connecting rod is installed on the lifting mechanism, and the lifting mechanism is used to raise and lower the connecting rod. When detecting underground metal objects with a metal detector, the driving mechanism is activated, causing slider B to move in the left and right direction. Slider B, through the connecting plates, causes the lifting mechanism to drive the connecting rod and the metal detector to move in the left and right direction. Since the metal detector can move in the left and right direction, the detection range of the metal detector is larger during detection, improving convenience.

[0007] Preferably, the driving mechanism includes a fixed plate, a drive motor, and a lead screw. The fixed plate is fixedly installed at the front end of the vehicle body, the drive motor is fixedly installed on the fixed plate, and the lead screw is rotatably installed on the fixed plate. The lead screw is screwed to the slider B, and the right end of the lead screw is connected to the output end of the drive motor. When it is necessary to drive the slider B to move in the left and right directions, the drive motor is turned on, and the drive motor drives the lead screw to rotate. The rotating lead screw causes the slider B to move in the left and right directions, which facilitates the left and right movement of the slider B.

[0008] Preferably, the lifting mechanism includes a support plate, a hydraulic cylinder, a lifting rod, a sliding rod, and a forward and backward moving mechanism. The support plate is fixedly installed on the left side of the two connecting plates, and the support plate is located on the left side of the vehicle body. The hydraulic cylinder is fixedly installed on the upper end of the support plate. The lifting rod and the sliding rod are both slidably installed on the support plate. The upper end of the lifting rod is connected to the output end of the hydraulic cylinder. The forward and backward moving mechanism is installed on the lower end of the sliding rod and the lifting rod. The connecting rod is installed on the forward and backward moving mechanism. When detecting underground metal objects, the hydraulic cylinder is opened, and the hydraulic cylinder drives the lifting rod to descend, which in turn lowers the forward and backward moving mechanism and the connecting rod, thereby lowering the metal detector to a position suitable for detecting underground metal. Since the height of the metal detector is adjustable, it can adjust the detection height of the metal detector according to the ground height, which facilitates the detection of underground metal objects.

[0009] Preferably, the forward and backward moving mechanism includes an electric slide rail and a sliding plate. The electric slide rail is fixedly installed at the lower end of the sliding rod and the lifting rod, and the sliding plate is installed on the electric slide rail. The electric slide rail is used to move the sliding plate forward and backward, and the connecting rod is fixedly installed at the lower end of the sliding plate. When the metal detector is used to detect underground metal objects, the electric slide rail is opened, and the electric slide rail drives the sliding plate to move in the forward and backward direction. The sliding plate moves the metal detector in the forward and backward direction through the connecting rod, which increases the detection range of the metal detector and improves convenience.

[0010] Preferably, the excavator is equipped with an indicator light; this feature improves the excavator's visibility, reminds nearby people not to approach, and enhances the safety of the excavator during operation.

[0011] Preferably, the surface of the bucket is provided with a wear-resistant coating; this improves the wear resistance of the bucket and extends its service life.

The excavator 1 is equipped with a vehicle body 2 and a bucket 3. The moving mechanism is installed on the vehicle body 2, and the metal detection mechanism is attached to the moving mechanism. The moving mechanism is used to move the metal detection mechanism, which has the function of detecting metal objects. When excavating in the demolition area of ​​an existing building, the excavator 1 is first moved to the area where the excavation work needs to be carried out. Then, the moving mechanism moves the metal detection mechanism to a position close to the ground. At the same time, the metal detection mechanism moves to detect underground steel bars and other metal embedded parts. Once a metal object is detected underground, the metal detection mechanism issues an alarm. Workers take precautions based on the location of the underground metal object and replan the excavation path to avoid it, minimizing the risk of collision between the bucket 3 on the excavator 1 and the metal object. This reduces the risk of damage to the bucket 3, reduces wear on the bucket 3, and improves the service life of the bucket 3. It is convenient to use and highly practical.

The connecting rod 4 is mounted on a moving mechanism, and the metal detector 5 is fixedly mounted on the connecting rod 4. When detecting underground metal objects, the moving mechanism causes the connecting rod 4 to move the metal detector 5 to a suitable detection position. After detection, the moving mechanism causes the connecting rod 4 to move the metal detector 5 to the front end of the vehicle body 2, so that the connecting rod 4 and the metal detector 5 are away from the area to be excavated, reducing the impact of the connecting rod 4 and the metal detector 5 on the excavation operation of the bucket 3; and facilitating the movement of the connecting rod 4 and the metal detector 5.

The lifting mechanism is installed on the left side of the two connecting plates 10, and is located on the left side of the vehicle body 2. Connecting rod 4 is installed on the lifting mechanism, and the lifting mechanism is used to raise and lower connecting rod 4. When the metal detector 5 is used to detect underground metal objects, the driving mechanism is activated, and the driving mechanism causes slider B9 to move in the left and right directions. Slider B9, through the connecting plates 10, causes the lifting mechanism to drive connecting rod 4 and metal detector 5 to move in the left and right directions. Since the metal detector 5 can move in the left and right directions, its detection range is larger, improving convenience.

[0024] As shown in Figures 3 and 4, the drive mechanism includes a fixed plate 11, a drive motor 12, and a lead screw 13.

The lead screw 13 is screwed onto the slider B9, and the right end of the lead screw 13 is connected to the output end of the drive motor 12. When it is necessary to drive the slider B9 to move in the left and right directions, the drive motor 12 is turned on, and the drive motor 12 drives the lead screw 13 to rotate. The rotating lead screw 13 causes the slider B9 to move in the left and right directions, which facilitates the left and right movement of the slider B9.

Since the height of the metal detector 5 is adjustable, its detection height can be adjusted according to the ground height, facilitating the detection of underground metal objects.
