Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery signal transmission technology, specifically to a rapid docking device for signal transmission carriers. Background Technology

[0002] Large tractor implements may require various forms of energy during operation, such as mechanical energy, hydraulic energy, and electrical energy. Mechanical energy generally refers to the torque transmitted from the tractor, which is the primary energy source for implement operation. Normal operation of implements also requires control signals to control their various movements, which necessitates the use of hydraulic or electrical signals.

[0003] Currently, there are connectors on the market that allow for quick connection or disconnection of hydraulic lines. These consist of male and female parts; when the male and female parts are connected, the line is open; when disconnected, the line is closed. However, they can only connect one line at a time, and the male and female connectors can only be manually connected. Agricultural implements typically require multiple hydraulic and electrical circuits to control cylinders or actuators. When connecting multiple hydraulic circuits, the male and female connectors require a specific order for each circuit, which is time-consuming. Incorrect connection order can cause the implement to malfunction or even damage it. Furthermore, quick-connect couplings also require disconnecting each circuit individually. The electrical connections are similarly complex. Therefore, there is an urgent market need for a device that can transmit both hydraulic and electrical signals while enabling rapid connection and disconnection. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a rapid docking device for signal transmission carriers that can quickly connect or disconnect multiple signal sources.

[0005] To solve the above-mentioned technical problems, one of the technical solutions adopted by this utility model is: A rapid docking device for signal transmission carriers includes: A front connector assembly, the front connector assembly including a front connector mounting plate, two or more hydraulic female plugs mounted on the front connector mounting plate, a guide sleeve mounted on the front connector mounting plate, a guide shaft slidably mounted inside the guide sleeve, the outer end of the guide shaft extending out of the guide sleeve and fixedly connected to a support plate, and a docking drive mechanism mounted on the support plate for driving the front connector mounting plate to move axially along the guide shaft; The rear connector assembly includes a rear connector mounting plate, on which a hydraulic male connector is mounted that can be plugged into the hydraulic female connector in a one-to-one correspondence; the rear connector mounting plate is also equipped with a guide positioning shaft that mates with the guide sleeve.

[0006] As a preferred technical solution, an electrical control socket module is mounted on the front connector mounting plate, and an electrical control plug module that can be plugged into the electrical control socket module is mounted on the rear connector mounting plate. Of course, the electrical control module can be replaced with different modules as needed, and can connect to various types of signals such as electrical signals, data signals, or optical signals.

[0007] As a preferred technical solution, the electrical control socket module is provided with a guide seat, and the electrical control plug module is provided with a guide pin that cooperates with the guide seat.

[0008] As a preferred technical solution, the hydraulic female plug is fixedly installed on the front connector mounting plate by a female plug locking nut, and a female plug retaining spring is provided on the outside of the female plug locking nut.

[0009] As a preferred technical solution, the hydraulic male plug is fixedly installed on the rear connector mounting plate by a male plug locking nut, and a male plug retaining spring is provided on the outside of the male plug locking nut.

[0010] As a preferred technical solution, each of the hydraulic male plugs is surrounded by a floating rubber sleeve.

[0011] As a preferred technical solution, a rain cover is installed on the top of the front connector mounting plate or the rear connector mounting plate.

[0012] As a preferred technical solution, the rear connector mounting plate is provided with hanging ears on both sides, and a hanging shaft is provided below the hanging ears.

[0013] As a preferred technical solution, the docking drive mechanism is a hydraulic cylinder, and the piston rod end of the hydraulic cylinder is fixedly connected to the front connector mounting plate.

[0014] To solve the technical problem described in this application, the present invention can also adopt a second technical solution, in which the hydraulic female plug is mounted on the rear connector mounting plate, and the hydraulic male plug is mounted on the front connector mounting plate. The specific technical solution is as follows: A rapid docking device for signal transmission carriers includes: A front connector assembly, the front connector assembly including a front connector mounting plate, two or more hydraulic male plugs mounted on the front connector mounting plate, a guide sleeve mounted on the front connector mounting plate, a guide shaft slidably mounted inside the guide sleeve, the outer end of the guide shaft extending out of the guide sleeve and fixedly connected to a support plate, and a docking drive mechanism mounted on the support plate for driving the front connector mounting plate to move axially along the guide shaft; The rear connector assembly includes a rear connector mounting plate, on which a hydraulic female connector is mounted that can be plugged into the hydraulic male connector in a one-to-one correspondence; and a guide positioning shaft that mates with the guide sleeve is mounted on the rear connector mounting plate.

[0015] Obviously, the second technical solution can also solve the technical problem described in this application and has the same technical effect as the first solution, and it also falls within the protection scope of this utility model.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: (1) In use, the front connector assembly is installed on the front mounting part of the device that enables the connection between the implement and the tractor, or on other devices. The rear connector assembly is installed on the rear mounting part of the device that enables the connection between the implement and the tractor, or on other devices. After the front and rear mounting parts are roughly positioned, the front and rear connector assemblies are at the same horizontal level. In this state, the front connector mounting plate is pushed to move axially by the docking drive mechanism. Under the guidance of the guide positioning shaft and the guide bushing, the front and rear connector mounting plates are initially positioned. When the front connector mounting plate continues to move forward, the hydraulic female plug and the hydraulic male plug first contact and dock, and then the electric control plug module and the electric control socket module begin to dock. When the hydraulic plug is connected, the guide pin of the electric control plug module is inserted into the guide seat of the electric control socket module to complete the connection and form a passage. This can realize the automatic connection between the front and rear connector assemblies, thereby realizing the transmission of multiple hydraulic signals and electrical signals. After the front connector mounting plate moves back and resets, the front and rear connector assemblies can be automatically separated without manual intervention, which can greatly improve the connection and separation efficiency.

[0017] (2) Different hydraulic and electrical control modules can be installed according to different requirements such as pressure and flow rate. Residual pressure connection is allowed. Hydraulic quick couplings and electrical control modules are easy to repair and replace.

[0018] (3) The structure is compact and occupies little space. After docking, it can self-lock to prevent accidental disconnection. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0022] In the description of this utility model, it should be noted that the terms "front" and "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. 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 element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figure 1 and Figure 2 As shown, the signal transmission carrier quick docking device includes a front connector assembly 100 and a rear connector assembly 200. When the front connector assembly 100 and the rear connector assembly 200 are combined, they can realize the transmission of multiple hydraulic signals and electrical signals.

[0024] Among them, reference Figure 3 and Figure 4The front connector assembly 100 includes a front connector mounting plate 101, on which two or more hydraulic female connectors 102 are mounted. In this embodiment, eight are used as an example, but other numbers are also possible and should all fall within the protection scope of this utility model. The hydraulic female connectors 102 can be selected according to actual needs such as pressure and flow rate. Specifically, each hydraulic female connector 102 is fixedly mounted on the front connector mounting plate 101 by a female connector locking nut 103. A female connector retaining ring 104 is provided on the outside of the female connector locking nut 103 to prevent the nut from loosening. It should be noted that the qualifier "female connector" in the terms "female connector locking nut" and "female connector retaining ring" is defined for the sake of convenience and does not indicate a specific structure. "Female connector locking nut" indicates a locking nut, and "female connector retaining ring" indicates a retaining ring, and so on.

[0025] A guide sleeve 105 is installed on the front connector mounting plate 101. A guide shaft 106 is slidably installed inside the guide sleeve 105. The outer end of the guide shaft 106 extends out of the guide sleeve 105 and is fixedly connected to a support plate 107. A docking drive mechanism 108 for driving the front connector mounting plate 101 to move axially along the guide shaft 106 is installed on the support plate 107. In this embodiment, the docking drive mechanism 108 is a hydraulic cylinder, and the piston rod end of the hydraulic cylinder is fixedly connected to the front connector mounting plate 101 by a nut.

[0026] refer to Figure 5 and Figure 6 The rear connector assembly 200 includes a rear connector mounting plate 201. The rear connector mounting plate 201 is equipped with hydraulic male connectors 202 that can be plugged into the hydraulic female connectors 102 one-to-one. Specifically, each hydraulic male connector 202 is fixedly mounted on the rear connector mounting plate 201 by a male connector locking nut 210. A male connector retaining ring 211 is provided on the outside of the male connector locking nut 210 to prevent the nut from loosening. The hydraulic male connectors 202 and hydraulic female connectors 102 are well-known structures in the art and will not be described in detail here. Each hydraulic male connector 202 is surrounded by a floating rubber sleeve 205 to calibrate the mating deviation between the hydraulic male connector 202 and the hydraulic female connector 102, preventing leakage and vibration. The rear connector mounting plate 201 is equipped with a guide positioning shaft 203 that mates with the guide sleeve 105. The head end of the guide positioning shaft 203 preferably has a tapered design for guiding and positioning.

[0027] See again Figure 3 and Figure 5The front connector mounting plate 101 is also equipped with an electrical control socket module 109, and the rear connector mounting plate 201 is equipped with an electrical control plug module 204 that can be plugged into the electrical control socket module 109. The electrical control socket module 109 is installed in a pre-drilled hole on the front connector mounting plate 101 via a floating device, and the electrical control plug module 204 is fixed in a pre-drilled hole on the rear connector mounting plate 201 by threads. The electrical control plug module 204 has guide pins 209 on both sides, and the electrical control socket module 109 has guide seats on both sides. The guide seats are equipped with floating devices to calibrate the mating deviation between the electrical control plug module 204 and the electrical control socket module 109. Of course, the electrical control module can be replaced with different modules as needed, and can connect to various signal types such as power, data, and fiber optics.

[0028] refer to Figure 5 A rain cover 206 is installed on the top of the rear connector mounting plate 201. Of course, the rain cover can also be installed on the top of the front connector mounting plate 101, which also has the effect of waterproofing and rain protection. Both should be within the protection scope of this utility model.

[0029] In this embodiment, the rear connector mounting plate 201 is provided with hanging ears 207 on both sides, and a cylindrical hanging shaft 208 is provided below the hanging ears 207. The hanging ears facilitate installation on other devices, and the hanging shaft 208 facilitates coarse positioning with other docking devices so as to achieve the front connector assembly and the rear connector assembly at the same horizontal height.

[0030] See again Figure 1 and Figure 2 The working principle of this utility model is as follows: In use, the front connector assembly 100 is installed on the front mounting part of the device that enables the connection between the implement and the tractor, or on another device. The rear connector assembly 200 is installed on the rear mounting part of the device that enables the connection between the implement and the tractor, or on another device. When the front and rear mounting parts are engaged, the front connector assembly 100 and the rear connector assembly 200 are roughly positioned at the same horizontal level. In this state, the movement of the hydraulic cylinder is controlled by the hydraulic valve. When the hydraulic cylinder extends, it pushes the front connector mounting plate 101 to move axially, and the guide positioning shaft 20... 3. Under the guidance of the guide sleeve 105, the front connector mounting plate 101 and the rear connector mounting plate 201 are initially positioned. When the front connector mounting plate 101 continues to move forward, the hydraulic female plug 102 and the hydraulic male plug 202 first make contact and dock. Then, the electric control plug module 204 and the electric control socket module 109 begin to dock. When the hydraulic plug is connected, the guide pin 209 of the electric control plug module 204 is inserted into the guide seat of the electric control socket module 109 to complete the connection and form a passage, thereby realizing the transmission of multiple hydraulic signals and electrical signals, and the cylinder self-locks to prevent disengagement.

[0031] During separation, the hydraulic cylinder is controlled to retract by controlling the hydraulic valve. After the front connector mounting plate 101 moves back to its original position, the electrical control plug module 204 separates from the electrical control socket module 109, and the hydraulic female plug 102 separates from the hydraulic male plug 202. In this way, the front connector assembly and the rear connector assembly can be automatically separated without manual intervention, which can greatly improve the connection and separation efficiency.

[0032] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model, such as swapping the installation of the hydraulic female plug and the hydraulic male plug, or swapping the installation of the electrical control plug module and the electrical control socket module, should fall within the protection scope of this utility model.
