Description

Technical Field

[0001] This application belongs to the field of special vehicle leveling technology, specifically relating to an inductive outrigger, a vehicle-mounted platform, and a vehicle. Background Technology

[0002] Many military and civilian vehicle-mounted devices require reliable support from a vehicle platform, such as vehicle-mounted transmitters, vehicle-mounted radars, and large cranes. Once these devices arrive at their designated locations, the vehicle's four outriggers, equipped with a leveling system, need to extend, reliably support, and level themselves. In the leveling system, hydraulic cylinder outriggers or electric cylinder outriggers are widely used. Regardless of the type used, the leveling process must first ensure that the outriggers reliably contact the ground. Then, leveling is performed based on the horizontal alignment of the outriggers on the special vehicle to avoid "false leveling," which would lead to unreliable leveling of the special vehicle. This step is generally referred to as ground compaction assessment.

[0003] In leveling systems using electric cylinder outriggers, the feedback circuit experiences a step change due to the load variation as the outrigger extends from unloaded to loaded. Therefore, the judgment is generally based on whether the step change in the motor feedback current of each outrigger meets a preset value. In leveling systems using hydraulic cylinder outriggers, the pressure within the cylinder cavity increases due to the load variation as the outrigger extends from unloaded to loaded. Therefore, the judgment is generally based on whether the pressure difference between the large and small cavities of each cylinder outrigger meets a preset value. Both methods rely on indirect parameters for judgment, which may be affected by environmental and system factors, leading to errors and inaccurate readings, thus affecting the leveling results. Summary of the Invention

[0004] To address the technical problem that current onboard platforms for special vehicles cannot provide reliable support, this application provides an inductive outrigger, an onboard platform, and a vehicle.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0008] In some embodiments, an oil groove is provided on the inner cylindrical surface of the first limiting member, and a grease nipple is connected to the outer side of the first limiting member. The grease nipple is connected to the oil groove and is used to inject grease into the oil groove.

[0009] In some embodiments, the first limiting member has a limiting groove at its upper end, and the cylinder has a protrusion that extends into the limiting groove, thereby limiting the rotation of the cylinder through the limiting groove.

[0012] A second aspect of this application provides a vehicle platform, wherein the vehicle platform has a mounting slot on its frame, and the inductive support leg is provided in the mounting slot.

[0013] In some embodiments, the sensing component includes a proximity switch fixed to the vehicle frame, the proximity switch being used to detect the size of the sensing gap and send a signal to the control system of the special vehicle.

[0014] In some embodiments, the mounting groove is a U-shaped groove, and a baffle is provided on the outside of the U-shaped groove.

[0015] A third aspect of this application provides a vehicle having the aforementioned onboard platform.

[0016] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

Detailed Implementation

[0028] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] Please see Figure 1 and Figure 2 .

[0030] Figure 1 This is a schematic diagram of the installation of a sensor-operated outrigger according to an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a sensor outrigger in an embodiment of this application. As shown in the figure, the sensor outrigger is used to support the vehicle platform of a special vehicle. At least two sensor outriggers 200 are provided on the vehicle platform. Specifically, the arrangement is based on the structure of the vehicle platform and the overall scheme of the special vehicle leveling vehicle. Two or four sensor outriggers 200 are provided on the frame 100, and the sensor outriggers 200 are respectively arranged at both ends of the frame 100.

[0031] In some embodiments, the sensing support leg 200 includes: a support leg body 210, including a cylinder 201 and a piston rod 202 disposed in the cylinder 201 and axially movable relative to the cylinder 201, the piston rod 202 having a support end protruding relative to the bottom end of the cylinder 201; a first limiting member 231, connected to the cylinder 201 and axially movable relative to the cylinder 201, the first limiting member 231 being fixedly connected to the moving platform; and a second limiting member 232, disposed on the cylinder 201. The first limiting member 231 and the bottom end of the cylinder 201 are located between them. An elastic member 233 is disposed between the first limiting member 231 and the second limiting member 232, and the elastic member 233 is in a compressed state. A sensing component is disposed at any one of the moving platform, the first limiting member 231, and the second limiting member 232, for detecting the distance between the second limiting member 232 and the moving platform, or for detecting the distance between the second limiting member 232 and the first limiting member 231. By setting the first limiting member 231 and the second limiting member 232 to further restrict the movement trajectory of the cylinder 201, the outrigger body 210 can be smoothly transmitted. By setting the trigger-type sensing component, when the sensing outrigger 200 contacts and presses against the ground, a ground-supporting compaction signal can be directly and reliably triggered, avoiding inaccurate judgment. This device has a simple structure, is easy to use, and can reliably support the vehicle-mounted platform of special vehicles.

[0032] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of the main body of an inductive outrigger according to this embodiment. As shown in the figure, in some embodiments, the main body 210 of the outrigger is a hydraulic cylinder or an electric cylinder, and the first limiting member 231 and the second limiting member 232 are limiting flanges.

[0033] In some embodiments, the support end of the piston rod 202 is connected to a foot plate 220, which is used to support the ground.

[0034] Specifically, the cylinder 201 is not only the main structure of the inductive outrigger 200, but also the main structure for load transmission. The piston rod 202 and the cylinder 201 form a cylindrical pair. Under power drive, the piston rod 202 extends and retracts along the cylinder 201. The supporting end of the piston rod 202 is connected to the foot plate 220 by a ball joint. The foot plate 220 can rotate freely around the ball head of the outrigger piston rod 202, ensuring that the inductive outrigger 200 can adapt to different terrains when it lands.

[0035] In some embodiments, a first limiting member 231 is sleeved on the upper part of the cylinder 201, and the first limiting member 231 is fixedly connected to the frame 100. The cylinder 201 can move axially along the first limiting member 231. A second limiting member 232 is sleeved and fixed on the lower part of the cylinder 201. The elastic member 233 is a compression spring, and the elastic member 233 is sleeved on the middle part of the cylinder 201. The two ends of the elastic member 233 are respectively connected to or abut against the first limiting member 231 and the second limiting member 232. The elastic member 233 is in a compressed state. The movement direction of the cylinder 201 is restricted by the first limiting member 231; the elastic member 233 is limited by the first limiting member 231 and the second limiting member 232 and is in a compressed pre-tightened state. When the outrigger 200 is in the driving state, it is subjected to its own weight and the thrust of the elastic member 233 to overcome the upward movement tendency caused by vibration during driving and keep it stationary in the vertical direction; the pre-tightening force of the compression member is generally set to twice the weight of the outrigger 200.

[0036] Please see Figure 4 , Figure 4 For this embodiment Figure 3 A magnified view of the area marked I;

[0037] In some embodiments, an oil groove 237 is provided on the inner cylindrical surface of the first limiting member 231, and a grease nipple 236 is connected to the outer side of the first limiting member 231, the grease nipple 236 being connected to the oil groove 237.

[0038] Specifically, the inner cylindrical surface of the first limiting member 231 is provided with an oil groove 237, which can be filled with grease through the grease nipple 236, and the moving parts of the cylinder 201 that contact the first limiting member 231 are plated with a hard coating, so that they can move for a long time without wear.

[0039] In some embodiments, the two ends of the inner cylindrical surface of the first limiting member 231 are provided with sealing grooves, and a sealing ring 238 is provided in the sealing groove to perform sealing and dust prevention functions.

[0040] Please see Figure 3 ;

[0041] In some embodiments, the lower part of the cylinder 201 is provided with threads, the second limiting member 232 is threadedly connected to the lower part of the cylinder 201, and a locking disc 234 is also provided at the lower end of the second limiting member 232 to fix the second limiting member 232.

[0042] Specifically, the second limiting member 232 and the locking disc 234 can rotate up and down to adjust the compression amount of the compression spring 233. After the second limiting member 232 is adjusted into place, the locking disc 234 can be tightened to interlock with the second limiting member 232 to prevent loosening.

[0043] In some embodiments, a sensing gap is provided between the upper end of the second limiting member 232 and the lower plane of the vehicle platform, and the sensing component is used to detect the size of the sensing gap.

[0044] The second aspect of this embodiment provides a mobile platform, wherein a mounting groove is provided on the frame 100 of the mobile platform, the inductive support leg 200 passes through the mounting groove, and a baffle 110 is provided on the outside of the mounting groove.

[0045] Specifically, the mounting groove is a U-shaped groove, and the sensing leg 200 can be installed or removed horizontally from the U-shaped groove. The central axis of the sensing leg 200 is coaxial with the central axis of the mounting groove. After the sensing leg 200 is installed in place, the first limiting member 231 is screwed to the upper surface of the mounting groove and fixed by the flange fastener 235 to achieve radial constraint on the sensing leg 200. The side of the mounting groove is sealed with a baffle 110 to avoid external environmental pollution. The upper section of the cylinder 201, extending beyond the mounting groove, is provided with an annular flange, serving as a limiting structure and load-bearing point during movement.

[0046] Please see Figure 5 , Figure 5 A cross-sectional view of a sensor-operated outrigger;

[0047] In some embodiments, a sensing gap is provided between the upper end of the second limiting member 232 and the lower plane of the mounting groove. The sensing component includes a proximity switch 300, which is fixed to the vehicle frame 100. The proximity switch 300 is used to detect the size of the sensing gap and send a signal to the control system of the feature vehicle.

[0048] Specifically, the second limiting member 232 has a gap of 10mm to 20mm between it and the lower surface of the mounting groove. As the sensing outrigger 200 extends and contacts the ground, it gradually compacts. The sensing outrigger 200 is subjected to the load of the vehicle and the reaction force of the ground. While compressing the compression spring 233, it moves upward as a whole, compressing the detection gap and triggering the proximity switch 300 to generate a signal, i.e., a direct ground compaction signal. After receiving the signal, the vehicle's control system can use this as a compaction criterion, which is the compaction state of the sensing outrigger 200.

[0049] After the leveling system is completed, the second limiting member 232 directly contacts the lower end face of the mounting groove. The vertical load of the whole vehicle is transmitted to the sensing leg 200 through the second limiting member 232, and the sensing leg 200 supports the vehicle.

[0050] In some embodiments, the proximity switch 300 is disposed in the internal threaded hole of the mounting groove. The proximity switch 300 can be finely adjusted along the threaded hole to ensure a suitable sensing distance. The proximity switch 300 is disposed along the internal channel of the mounting groove to avoid damage from the external environment.

[0051] In some embodiments, the outrigger body 210 further includes: a first dust cover 203, fixed to the upper end of the cylinder 201; and a second dust cover 204, fixed to the lower end of the cylinder 201. This further prevents the impact of sand and rain. The first dust cover 203 and the second dust cover 204 are fastened to the inductive outrigger 200 by clamps 205.

[0052] Please see Figure 6 , Figure 6 This is a schematic diagram of a partial structure of a sensor-operated outrigger;

[0053] In some embodiments, the first limiting member 231 has a limiting groove at its upper end, and the cylinder 201 has a protrusion that extends into the limiting groove, thereby limiting the rotation of the cylinder 201 through the limiting groove.
