Description

Technical Field

[0001] This utility model belongs to the field of equipment monitoring technology, specifically an excavator with a communication tag. Background Technology

[0002] In order to automatically record data such as the amount of goods loaded by the excavator and the number of transport trips by the truck when the excavator is loading the truck, a monitoring system is installed on the excavator and the truck. By installing short-range wireless communication devices on the excavator and the truck, if the wireless communication device on the excavator establishes a communication connection with the wireless communication device on a truck, it means that the two are very close, and thus it means that the excavator is loading the truck.

[0003] The invention patent with authorization announcement number CN115075328B discloses a confirmation device and method for loading excavators onto trucks. By setting up an excavator monitoring device and a truck monitoring device, the excavator can automatically determine the truck it is loading onto. Through matching via a first short-range wireless communication module and a second short-range wireless communication module, it can accurately determine which truck the excavator is loading onto. Even in dense loading sites where excavators are very close together, it can accurately determine the loading matching relationship between the excavator and the truck.

[0004] In practical use, the excavator's communication tag (i.e., the first short-range wireless communication module) is fixed to the excavator's bucket cylinder, while the truck's communication tag (i.e., the second short-range wireless communication module) is fixed to the top of an upward-extending pole on the side of the truck cab. Due to national construction safety regulations, for the safety of truck drivers, excavators are not allowed to load trucks in front of the truck cab. Therefore, when loading trucks with an excavator, there are several... Figure 1 The seven location scenarios are shown. The communication tag settings described above apply to three scenarios: the excavator loading from the left rear of the truck, the right rear of the truck, and directly behind the truck. Figure 1 Cases (c), (f), and (g) are relatively adaptable and communication is smooth. However, for the four scenarios where the excavator is loading on the left or right side of the truck cab (also known as "reverse loading"), or loading in the middle of the left or right side of the truck, the communication is not as smooth. Figure 1 In cases (a), (b), (d), and (e), the structure such as the bucket arm and the excavator body can block the communication tag between the excavator and the truck, resulting in poor communication and frequent "communication failure" and inability to match. Utility Model Content

[0005] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide an excavator equipped with a communication tag, so as to enable the excavator and the truck's communication tag to be successfully matched in any loading scenario.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An excavator with a communication tag includes a body, a boom, a stick, and a bucket. The boom, stick, and bucket are all driven by hydraulic cylinders. A communication tag is fixed on the excavator. The communication tag is fixed on at least one of the bucket cylinder, boom, stick, and bucket hydraulic pipe. The communication tag includes a first tag and a second tag that are symmetrically arranged on the excavator. The included angle between the first tag and the second tag is an obtuse angle.

[0007] As a limitation of this utility model: the included angle between the first label and the second label is 120°.

[0008] As a limitation of this utility model: the first label and the second label are respectively fixed on the two bucket oil pipes on both sides of the bucket cylinder.

[0009] As a limitation of this utility model: the first label and the second label are fixed to the bucket oil pipe by clamps, and an angle adjustment device for adjusting the label angle is fixed between the corresponding label and the clamp.

[0010] As a limitation of this utility model: the angle adjustment device includes a base fixed on the clamp, and a label fixing seat rotatably connected to the base. The base has a plurality of first fixing holes arranged in a circumferential array, and the label fixing seat has a second fixing hole. The angle adjustment device also includes a threaded fastener that passes through both the second fixing hole and the first fixing hole.

[0011] As a limitation of this utility model: the communication tag also includes a third tag fixed on the bucket cylinder and positioned forward.

[0012] As a limitation of this utility model, the communication tag is any one of Bluetooth module, WIFI module, LoRa module, 433M, wireless module, and UWB module.

[0013] As a limitation of this utility model: the third label is fixed to the cylinder body of the bucket cylinder by a clamp.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0015] This invention, through a rational design of the communication tag's position on the excavator, ensures smooth matching between the excavator and truck's communication tags in any loading scenario. The first and second tags are positioned at an obtuse angle, allowing their signals to completely cover the excavator's bucket's left front, right front, and front sides. This guarantees compatibility in four loading scenarios: the excavator is loading on the left or right side of the truck cab, or in the middle of the left or right side of the truck. Figure 1The invention relates to the communication between the excavator and the truck in four scenarios (a), (b), (d), and (e), while also ensuring communication between the excavator and the truck in other scenarios. Furthermore, the invention includes a third tag facing directly forward to further enhance the signal strength, especially when the excavator is loading from the left rear, right rear, or directly behind the truck (corresponding to...). Figure 1 In cases (c), (f), and (g), the label directly in front can also serve as a double insurance, further ensuring communication between the excavator and the truck.

[0016] In summary, this utility model enables the communication tags of the excavator and the truck to match smoothly in any loading scenario, and is applicable to the communication matching between the excavator and the truck when the excavator is loading the truck. Attached Figure Description

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the excavator with communication tags described herein is a preferred embodiment and is only used for illustration and explanation of the present invention, and does not constitute a limitation thereof.

[0030] The directional terms or positional relationships used in this utility model, such as "up," "down," "left," and "right," are based on the positional relationships in the accompanying drawings of this utility model. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model. Example

[0031] This implementation example Figure 2 , Figure 3 The image shows an excavator with a communication tag, including a body, boom 1, stick 2, and bucket 3. The boom 1 is driven by a boom cylinder, the stick 2 by a stick cylinder, and the bucket 3 by a bucket cylinder 4. To enable these cylinders to operate, hydraulic pipes for supplying hydraulic oil are connected to both sides of each cylinder. To more clearly illustrate the structure of this embodiment, Figure 2 The diagram only shows the excavator structure related to the location of the communication tag, such as the boom 1 and bucket 3, and the structure of the excavator is not limited to this embodiment.

[0032] A communication tag is fixed on the excavator. The communication tag can be selected from any one of the following modules: Bluetooth, WIFI, LoRa, 433M wireless, or UWB. In this embodiment, the communication tag includes a first tag 5 and a second tag 6 symmetrically mounted on the excavator. The first tag 5 and the second tag 6 are respectively fixed to two bucket hydraulic pipes on both sides of the bucket cylinder. The first tag 5 and the second tag 6 are positioned facing the left front and right front of the excavator, respectively, forming an angle of 120°. Of course, the angle between the first tag 5 and the second tag 6 can be adjusted as needed, as long as it is an obtuse angle that allows the signal to cover the left front, right front, and front of the excavator. Besides the bucket hydraulic pipes, the first tag 5 and the second tag 6 can also be symmetrically mounted on at least one of the following components: the bucket cylinder 4, the stick 2, and the boom 1. That is, the first tag 5 and the second tag 6 can be symmetrically mounted on the same component, or they can be mounted on different components, as long as the first tag 5 and the second tag 6 are symmetrically mounted.

[0033] The first label 5 and the second label 6 are fixed to the bucket oil pipe by clamps. To facilitate adjustment of their orientation, an angle adjustment device for adjusting the label angle is fixed between the corresponding label and the clamp. Figure 3 As shown, the angle adjustment device includes a base 7 fixed on the clamp, and a label fixing seat 8 rotatably connected to the base 7. The base 7 has a plurality of first fixing holes 9 arranged in a circumferential array, and the label fixing seat 8 has a second fixing hole 10. The angle adjustment device also includes a threaded fastener (not shown in the figure) that passes through both the second fixing hole 10 and the first fixing hole 9. By using the threaded fastener to simultaneously pass through the second fixing hole 10 and different first fixing holes 9, the angle of the first label 5 and the second label 6 can be adjusted and fixed.

[0034] It should be noted that since the optimal included angle between the first label 5 and the second label 6 is 120°, when it is not necessary to adjust the included angle between the first label 5 and the second label 6, the angle adjustment device can be omitted, and the first label 5 and the second label 6 can be directly fixed to the bucket oil pipe or other positions by clamps. When it is necessary to adjust the included angle between the first label 5 and the second label 6, the angle adjustment device can be set as needed.

[0035] Furthermore, to enhance signal coverage directly in front, the communication tag also includes a third tag 11 fixed to the bucket cylinder 4 and positioned facing forward. The third tag 11 is fixed to the cylinder body of the bucket cylinder 4 by a clamp and faces forward of the excavator. Since the boom 1 is made of welded steel plates and has a relatively large thickness, the third tag 11 needs to be installed simultaneously when the first tag 5 and the second tag 6 are symmetrically installed on the boom 1.

[0036] When the excavator is loading the truck on the left and right sides of the cab, or in the middle of the left and right sides of the truck, that is... Figure 1 In scenarios (a), (b), (d), and (e), communication between the excavator and the truck is primarily ensured by the first tag 5 and the second tag 6. This communication occurs when the excavator is loading the truck from the left rear, right rear, or directly behind the truck. Figure 1 In scenarios (c), (f), and (g), communication between the excavator and the truck can be guaranteed by the first tag 5 and the second tag 6. If the signal is poor, it can also be further guaranteed by the third tag 11, so that the excavator can communicate smoothly with the truck's communication tag when loading the truck at various locations.
