Description

Technical Field

[0001] The utility model relates to the technical field of electric outriggers, in particular to a special electric outrigger for a tractor trailer. Background Art

[0002] Tractor trailers are an indispensable means of transport in the transportation industry. They are connected by a tractor-trailer, forming a combination that can be both driven as a whole and flexibly separated. This design enables tractor-trailers to efficiently complete various cargo transport tasks.

[0003] Outriggers for tractor trailers (particularly semitrailer outriggers) play a vital role in the transportation industry. Their primary functions can be summarized as follows: Support: When a semitrailer is detached from the tractor, the outriggers support the front of the trailer, bearing the weight of the trailer and its cargo, ensuring it remains securely on the ground. Stabilization: The outriggers ensure balance and stability when loading and unloading cargo or awaiting dispatch, preventing sway or tilting due to uneven ground or wind, thereby protecting the cargo and the vehicle. Safety: The outriggers can withstand heavy loads and wear, providing strong support for transport personnel and playing a crucial role in transportation safety. Protection: The outriggers also protect the trailer from accidental movement or collisions when not in use, providing a degree of protection. Adaptability: The outriggers are designed to be flexible and adaptable to varying ground conditions and operational requirements, providing stable support on both flat warehouse floors and rugged field conditions.

[0004] The outriggers are usually installed at the front end of the semi-trailer frame to provide support after the semi-trailer is separated from the tractor. They are mostly used for cargo packing at container ports and various logistics centers, dispatching of tractors, etc. However, the outriggers are generally installed and supported manually when in use, which is time-consuming, labor-intensive, and has low work efficiency. Therefore, there is an urgent need for an electric outrigger specifically for tractor trailers to solve the above problems. Summary of the Invention

[0005] In response to the problems that current outriggers are time-consuming and labor-intensive and have low work efficiency when in use, the utility model proposes an electric outrigger specially designed for a tractor trailer. The outrigger is electrically driven, which saves time and effort, can effectively improve work efficiency, does not require manual operation by staff, and reduces the labor intensity of staff.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is a special electric outrigger for tractor trailers, comprising an outrigger body, a drive motor installed on the outrigger body, a motor brake installed on the drive motor, and an adjustment handle, a non-return mechanism, a power interface, a power switch and a control button installed on the outrigger body. When in use, the outrigger body is first supplied with electric energy through the power interface, the supply and interruption of electric energy is controlled by the power switch, and the drive motor is controlled to start by the control button, so that the drive motor drives the outrigger body to rise or fall. When the outrigger body reaches the specified height, the drive motor is braked by the motor brake, and the outrigger body is locked by the non-return mechanism, so that the outrigger body can achieve a supporting effect. The overall operation is simple and easy to use. At the same time, the lifting height of the outrigger body can be adjusted by the adjustment handle, so that the outrigger is suitable for tractor trailers of different heights, and the scope of application is wider.

[0007] Furthermore, an oil filling port is installed on the support leg body, through which the support leg body can be lubricated and maintained.

[0008] Furthermore, a current overload protector is connected in series between the power interface and the drive motor, and the drive motor can be protected from overload by the current overload protector.

[0009] Furthermore, a power indicator light is connected in series to the power switch, so that the staff can observe the power-on status through the power indicator light.

[0010] Furthermore, a rotating base is provided at the bottom of the leg body. By rotating the base, the leg body is adapted to be used on uneven ground, and has a wider range of applications.

[0011] Furthermore, a self-locking elastic pin is provided on the anti-return mechanism, which can prevent the support leg from falling through the self-locking elastic pin, thereby further improving the safety of the support leg.

[0012] The beneficial effects of the utility model are:

[0013] The electric outrigger brakes the driving motor through the motor brake and locks the outrigger body through the anti-return mechanism, allowing the outrigger body to achieve a supporting function. The overall operation is simple and easy to use. At the same time, the height of the outrigger body can be adjusted by adjusting the handle, making the outrigger suitable for tractor trailers of different heights and having a wider range of applications.

[0017] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0018] like Figure 1 As shown, in this embodiment, the utility model proposes an electric outrigger specially used for tractor trailers, including an outrigger body 1, an oil filling port 3 is installed on the outrigger body 1, and the oil filling port 3 is used to facilitate lubrication and maintenance of the outrigger body 1, and a rotating base is provided at the bottom of the outrigger body 1, and the rotating base makes the outrigger body 1 suitable for rugged and uneven ground, and has a wider range of applications, a driving motor 9 is installed on the outrigger body 1, and a motor brake 10 is installed on the driving motor 9, and an adjustment handle 2, a non-return mechanism 6, a power interface 4, a power switch 8 and a control button 11 are also installed on the outrigger body 1, and a self-locking elastic pin is provided on the non-return mechanism 6, which can prevent the outrigger from falling, thereby further improving the safety of the outrigger (the non-return mechanism 6 is common knowledge known to people in this field and will not be elaborated on here).

[0019] The adjusting handle 2 is installed on the side of the leg body 1 and is fixed by a nut. When adjustment is needed, the nut is loosened to raise or lower the adjusting handle 2 to control the degree of raising of the leg body 1. After the adjustment height is determined, the nut is tightened again to lock the adjusting handle 2. A proximity switch is installed on the adjusting handle 2. By adjusting the position of the proximity switch, when the driving motor 9 drives the leg body 1 to rise or fall, the moving part of the leg body 1 will trigger the proximity switch, cut off the power to the driving motor 9, and stop adjusting the leg body 1.

[0020] Specifically, the leg body 1 includes a pillar, which is installed on a rotating base, and a top rod is connected to the upper part of the pillar. A driving motor 9 is installed on the pillar, and a gear is installed on the output end of the driving motor 9 through a reducer. A rack is provided on the top rod, and the rack is meshed with the gear. The gear is driven to rotate by the driving motor 9, and the rack is driven by the gear to move up and down, thereby driving the top rod to move up and down, thereby realizing the raising or lowering of the leg body 1. A sliding groove is provided on the side of the pillar, and the adjusting handle 2 is slidably connected on the inner side of the sliding groove, and the adjusting handle 2 is locked by a nut. A protrusion is provided on the top rod, and the protrusion can trigger the proximity switch. When the protrusion triggers the proximity switch, the driving motor 9 stops running. By adjusting the height of the adjusting handle 2, the raising or lowering height of the top rod can be limited.

[0021] A current overload protector 5 is connected in series between the power interface 4 and the drive motor 9. The current overload protector 5 can protect the drive motor 9 from overload. A power indicator light 7 is also connected in series to the power switch 8. The power indicator light 7 allows staff to observe the power-on status. When in use, first, the power interface 4 is used to provide power to the outrigger body 1, and the power switch 8 is used to control the supply and interruption of power. The control button 11 is used to control the drive motor 9 to start, so that the drive motor 9 drives the outrigger body 1 to rise or fall. When the outrigger body 1 reaches the specified height, the drive motor 9 is braked by the motor brake 10, and the anti-return mechanism 6 is used to lock the outrigger body 1, so that the outrigger body 1 can achieve the supporting function. The overall operation is simple and easy to use. At the same time, the lifting height of the outrigger body 1 can be adjusted by adjusting the handle 2, so that the outrigger is suitable for tractor trailers of different heights, and the scope of application is wider (the internal circuit connection of the electric outrigger is common knowledge for those skilled in the art and will not be described in detail here).

[0022] In addition, as a preference, the legs can be manually operated by staff without power supply.

[0023] Specifically, first use a tool to open the tail cover of the drive motor 9, use a wrench to release the motor brake 10, and then use the wrench to rotate the shaft of the drive motor 9 counterclockwise to drive the support leg to rise. At this time, the support leg can only be raised and cannot be retracted; if the support leg needs to be retracted, it is necessary to use a tool to open the sealing cover of the anti-return mechanism 6, and then the staff will pull out the self-locking elastic pin inside the anti-return mechanism 6, and then use a wrench to rotate the shaft of the drive motor 9 clockwise to drive the support leg to retract. After the retraction is completed, the self-locking elastic pin is inserted into the anti-return mechanism 6 to ensure the normal use of the anti-return mechanism 6.

[0024] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
