Description

Technical Field

[0001] The utility model relates to the technical field of aircraft, in particular to an anchor parking leg mechanism. Background Art

[0002] In the ground equipment of a moored airship, a support mechanism is required to support the mooring platform and level the mooring platform at the same time. A mooring tower for connecting the airship is often arranged on the mooring platform. Since the airship is easily affected by wind when moored, it is necessary to enhance the anti-overturning ability of the mooring platform. Existing mooring platforms include fixed type and mobile type. The support mechanism of the fixed moored airship mooring platform is usually fixedly connected to the ground and can bear a large vertical load, but it cannot be transferred and moved; the support mechanism of the mobile moored airship mooring platform is usually fixedly connected to the anchor parking vehicle, which can level the mooring platform and adapt to vehicle transportation, but the horizontal load-bearing capacity of the support mechanism is poor. Therefore, in order to improve the mobility and stability of the support mechanism, a leg mechanism that can be folded and can help increase the anti-overturning ability of the support mechanism during mooring is required. Summary of the Utility Model

[0003] The utility model aims to provide an anchor parking leg mechanism to provide a leg mechanism that can be folded and can help increase the anti-overturning ability of the support mechanism during mooring.

[0004] To achieve the above object, the utility model adopts the following technical scheme: an anchor parking leg mechanism, which includes a support arm, a support arm mounting seat and two locking mechanisms. The support arm is rotatably connected to the support arm mounting seat. The support arm mounting seat is mounted on the support mechanism. When the support arm is perpendicular to the support mechanism and when the support arm is folded with the support mechanism, the support arm is respectively clamped and limited by a locking mechanism. A leg part is provided at one end of the support arm away from the support arm mounting seat. The leg part includes a hydraulic telescopic rod and a support. The support is hinged to the bottom of the hydraulic telescopic rod, and the upper end of the hydraulic telescopic rod is fixedly connected to the support arm.

[0005] The beneficial effects of this solution are as follows:

[0006] By setting the locking mechanism to limit the support arm, it is ensured that the support arm can be firmly locked in both the open and folded states, preventing structural instability caused by accidental loosening, such as the vibration during transportation.

[0007] After the support arm is unfolded, the hydraulic telescopic rod drives the support base to slide downward until it touches the ground. The hydraulic telescopic rod can adjust its length as needed to adapt to the height differences of different ground surfaces, ensuring stable support of the mooring platform on different terrains. In addition, the support base is hinged to the bottom of the hydraulic telescopic rod, enabling the support base to adaptively adjust according to the angle and unevenness of the ground, thereby ensuring full contact between the support base and the ground and improving the stability of the support. Through the cooperation of the hydraulic telescopic rod and the support base, the support arm can effectively disperse the load after unfolding, reducing the risk of the equipment tipping over on uneven ground.

[0008] Preferably, as an improvement, the locking mechanism includes a lock pin mounting seat, a sliding lock pin, and a spring. The lock pin mounting seat is also provided with a spring seat. The spring is placed inside the spring seat. One end of the sliding lock pin is inserted into the spring seat and abuts against the spring. A slide bar is fixed to this end of the sliding lock pin. A chute for the slide bar to slide is opened on the spring seat to limit the sliding lock pin.

[0009] The beneficial effects are as follows: The sliding lock pin is clamped with the support arm under the action of the spring force, realizing quick and simple automatic locking, reducing the complexity of the operation, and improving the efficiency of the process of unfolding or folding the support arm. When it is necessary to release the clamping, pull the slide bar by hand to make the slide bar slide along the chute to overcome the spring force, and then the support arm can be taken out. No additional tools or the assistance of multiple people are required, and a single person can complete it, improving the work efficiency. At the same time, the chute can limit the sliding direction and sliding distance of the sliding lock pin to ensure that the sliding lock pin slides within the set distance range.

[0010] Preferably, as an improvement, the lower surface of the sliding lock pin is an inclined surface.

[0011] The beneficial effects are as follows: When the support arm moves to the locking position, the inclined surface of the sliding lock pin will contact the support arm and automatically slide into the clamping position under the push of the spring. The setting of the inclined surface reduces the frictional resistance, enabling the sliding lock pin to slide more smoothly to the locking position.

[0012] Preferably, as an improvement, both the support base and the hydraulic telescopic rod are rotationally connected through spherical hinge parts. The spherical hinge part includes a limit mounting plate and a spherical end connected to the hydraulic telescopic rod. The support base includes a mounting part and a bottom plate provided at the bottom of the mounting part. A spherical groove for mating with the spherical end is opened on the mounting part. The limit mounting plate and the upper surface of the mounting part are fixedly connected by bolts to limit the spherical end in the spherical groove. Angle sensors are also provided on the hydraulic telescopic rods.

[0013] The beneficial effects are as follows: By setting the connection of the spherical hinge parts, the support base can always stably adhere to the ground when the hydraulic telescopic rod extends, ensuring the stability of the support arm placed on the ground. Angle sensors are also provided on the hydraulic telescopic rods, which can detect the inclination angle of each support base. When the support base is about to reach the tipping critical value, the angle sensor can sense it in time, facilitating reminding the operator to make adjustments and preventing the occurrence of tipping accidents.

[0014] Preferably, as an improvement, a photoelectric alarm is further provided on the hydraulic telescopic rod, and pressure sensors are provided at the bottom of the support, and the pressure sensors are electrically connected to the photoelectric alarm.

[0015] The beneficial effect is that when multiple pressure sensors sense uneven pressure and there is a risk of tipping, the photoelectric alarm can quickly give an alarm to remind the operator to take measures to avoid accidents.

[0016] Preferably, as an improvement, clamping plates are fixed on both sides of the support arm, and openings for the sliding locking pins to pass through are provided at the ends of the clamping plates.

[0017] Preferably, as an improvement, a plurality of reinforcing plates are further provided at the connection between the bottom plate and the installation part. Description of the Drawings

[0022] The following is a further detailed description through specific embodiments:

[0023] The reference numerals in the accompanying drawings of the specification include: support arm 1, support arm mounting seat 2, hydraulic telescopic rod 3, support 4, locking pin mounting seat 5, sliding locking pin 6, spring 7, spring seat 8, sliding rod 9, sliding groove 10, mounting plate 11, spherical end 12, mounting part 13, bottom plate 14, clamping plate 15, reinforcing plate 16, bolt 17.

[0024] Embodiment 1

[0025] Embodiment 1 is basically as Figures 1-4 shown, as Figure 1 and Figure 2An anchor parking outrigger mechanism shown in the figure includes an outrigger arm 1, an outrigger arm mounting seat 2 and two locking mechanisms. The outrigger arm 1 is rotatably connected to the outrigger arm mounting seat 2. The outrigger arm mounting seat 2 is fixedly installed on the support mechanism through bolts 17. When the outrigger arm 1 is perpendicular to the support mechanism and when the outrigger arm 1 is folded together with the support mechanism, it is respectively clamped and limited by a locking mechanism. At one end of the outrigger arm 1 away from the outrigger arm mounting seat 2, outrigger legs are provided. The outrigger legs include a hydraulic telescopic rod 3 and a support 4. The support 4 is hinged to the bottom of the hydraulic telescopic rod 3, and the upper end of the hydraulic telescopic rod 3 is fixedly connected to the outrigger arm 1.

[0026] As Figure 4 shown, the locking mechanism includes a lock pin mounting seat 5, a sliding lock pin 6 and a spring 7. A spring seat 8 is also provided on the lock pin mounting seat 5. The spring 7 is placed in the spring seat 8. One end of the sliding lock pin 6 is inserted into the spring seat 8 and abuts against the spring 7. A slide bar 9 is also fixed to this end of the sliding lock pin 6. A slide groove 10 for the slide bar 9 to slide is opened on the spring seat 8 to limit the sliding lock pin 6. The sliding lock pin 6 is clamped with the outrigger arm 1 under the elastic force of the spring 7, realizing fast and simple automatic locking, reducing the complexity of operation, and improving the efficiency of the outrigger arm 1 during the unfolding or folding process; when it is necessary to release the clamping, pull the slide bar 9 by hand, so that the slide bar 9 slides along the slide groove 10 to overcome the elastic force of the spring 7, and the outrigger arm 1 can be taken out. No additional tools or the assistance of multiple people are required, and a single person can complete it, improving the work efficiency; at the same time, the slide groove 10 can limit the sliding direction and sliding distance of the sliding lock pin 6 to ensure that the sliding lock pin 6 slides within the set distance range. The lower surface of the sliding lock pin 6 in this embodiment is an inclined surface. When the outrigger arm 1 moves to the locking position, the inclined surface of the sliding lock pin 6 will contact the outrigger arm 1 and automatically slide into the clamping position under the push of the spring 7. The setting of the inclined surface reduces the frictional resistance and enables the sliding lock pin 6 to slide more smoothly to the locking position; As Figure 3 shown, clamping plates 15 are fixed on both sides of the outrigger arm 1, and through holes for the sliding lock pin 6 to pass through are opened at the ends of the clamping plates 15.

[0027] The support 4 and the hydraulic telescopic rod 3 are both rotatably connected through spherical hinge parts. The spherical hinge parts include a limit mounting plate 11 and a spherical end 12 connected to the hydraulic telescopic rod 3. The support 4 includes a mounting part 13 and a bottom plate 14 provided at the bottom of the mounting part 13. A spherical groove matching with the spherical end 12 is opened on the mounting part 13. The limit mounting plate 11 and the upper surface of the mounting part 13 are fixedly connected through bolts 17 to limit the spherical end 12 in the spherical groove. Angle sensors are also provided on the hydraulic telescopic rods 3. By setting the connection of the spherical hinge parts, the support 4 can always stably adhere to the ground when the hydraulic telescopic rod 3 extends, ensuring the stability of the outrigger arm 1 placed on the ground. Angle sensors are also provided on the hydraulic telescopic rods 3, which can detect the inclination angle of each hydraulic telescopic rod 3. When the support 4 is about to reach the tipping critical value, the angle sensor can sense it in time, facilitating the reminder for the operator to make adjustments and preventing the occurrence of tipping accidents. As Figure 2As shown, in this embodiment, a plurality of reinforcing plates 16 are further provided at the connection between the bottom plate 14 and the mounting portion 13 to ensure the connection strength of the connection and improve the service life of the connection.

[0028] The specific implementation process is as follows:

[0029] After the support arm 1 is unfolded, the hydraulic telescopic rod 3 drives the support 4 to slide downward until it abuts against the ground. The hydraulic telescopic rod 3 can adjust its length as needed to adapt to the height difference of different ground surfaces, ensuring stable support of the mooring platform on different terrains. In addition, the support 4 is hinged to the bottom of the hydraulic telescopic rod 3, enabling the support 4 to adaptively adjust according to the angle and unevenness of the ground, so as to ensure full contact between the support 4 and the ground and improve the stability of the support. Through the cooperation of the hydraulic telescopic rod 3 and the support 4, the support arm 1 can effectively disperse the load after being unfolded, reducing the risk of the equipment tipping over on uneven ground. In this embodiment, a locking mechanism is provided to limit the support arm 1, ensuring that the support arm 1 can be firmly locked in both the open and closed states, preventing structural instability caused by accidental loosening, such as vibration during transportation.

[0030] Embodiment 2

[0031] The difference between Embodiment 2 and Embodiment 1 is that in this embodiment, a photoelectric alarm is further provided on the hydraulic telescopic rod 3, and pressure sensors are provided at the bottom of the supports 4. The pressure sensors are electrically connected to the photoelectric alarm. When the plurality of pressure sensors sense uneven pressure and there is a risk of tipping, the photoelectric alarm can quickly issue an alarm to remind the operator to take measures to avoid accidents.
