Description

Technical Field

[0001] This utility model belongs to the field of radar repair, and in particular, it is a parking device for a radar repair vehicle. Background Technology

[0002] Radar antennas are important radar components. Due to their large weight, a radar repair cart was created as a dedicated repair platform to reduce the need for transporting the antennas between different repair stations. The radar repair cart can be directly and securely mounted on the radar repair cart, which is equipped with casters for easy movement of the radar antennas.

[0003] The casters under the radar repair vehicle allow it to move, but during repair and testing phases, the vehicle needs to have good braking stability. While casters with brakes can be used to park the repair vehicle, these only restrict the rolling motion of the casters, and the contact area between the casters and the ground is small, resulting in unsatisfactory braking performance. Adding helical supports under the radar repair vehicle provides better braking, but requires rotating each helical support individually, making the operation extremely cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide a parking device for a radar repair vehicle. By pressing down on the handle, multiple downward supports can be quickly obtained, thereby achieving the fixation and stability of the parking position.

[0005] The technical solution to achieve the purpose of this utility model is as follows: a parking device for a radar repair vehicle, including a frame, a handle component, a connecting rod component, and a brake component; the handle component is rotatably connected to the frame, the end of the handle component is rotatably connected to the connecting rod component, the end of the connecting rod component is hinged to the frame, and the bottom of the connecting rod component is connected to the brake component. Through the movement of the connecting rod component, the brake component is driven to adjust its angle, thereby realizing the parking of the radar repair vehicle.

[0006] Compared with the prior art, the significant advantages of this utility model are:

[0007] (1) The parking device of the radar repair vehicle designed in this utility model can brake by simply pressing down the handle and cancel the brake by lifting the handle, which simplifies the operation and is very efficient.

[0008] (2) The parking device of the radar repair vehicle designed in this utility model provides support and friction in four directions at the same time, resulting in a good parking effect.

[0009] (3) The parking device of the radar repair vehicle designed in this utility model can form a self-locking mechanism when the lever is pulled down, and the system has good stability. When the handle is rotated to the bottom, the force between the handle component 2 and the connecting rod component 3 remains perpendicular. No matter how much reverse force the brake component 4 applies to the vertical connecting rod 3-4, it will not cause the parking function to fail.

[0010] (4) The damper installed in this device can effectively absorb excess support stroke and maintain the balance of the support.

[0011] (5) The contact area between the device and the bottom surface is made of rib material, which has high friction and good parking effect.

[0012] (6) The handle of the device is attracted to the frame by a strong magnet, which not only does not affect the pushing of the frame, but also facilitates the use of the parking function at any time. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-9 The present invention will be further described in detail with reference to specific embodiments.

[0023] A parking device for a radar repair vehicle includes: a frame 1, a handle assembly 2, a linkage assembly 3, and a brake assembly 4.

[0024] The frame 1 is welded from angle steel, with a mounting plate on top for mounting the radar antenna and casters on the bottom for moving the radar repair vehicle.

[0025] Handle component 2 includes: grip bar 2-1, side plate 2-2, connecting plate 2-3, transition block 2-4, strong magnet 2-5, fixed shaft 2-6, fixed seat 2-7, and drive shaft 2-8.

[0026] Side plates 2-2 are fixedly installed at both ends of the grip bar 2-1 by screws;

[0027] The two ends of the connecting plate 2-3 are fixedly installed between the two side plates 2-2 by the transition block 2-4. The connecting plate 2-3 is made of steel plate bent into an L shape (the cross section is L-shaped). The strong magnet 2-5 is installed on the connecting plate 2-3, and when the grip bar 2-1 is in the highest position, the strong magnet 2-5 is attracted to the frame body 1.

[0028] The fixed shaft 2-6 is installed between the two side plates 2-2, and the stepped shafts at both ends are rotatably connected to the fixed seat 2-7. The fixed seat 2-7 is fixedly installed on the frame body 1 by screws. The fixed shaft 2-6 is the rotating shaft of the handle component 2 around the frame body 1.

[0029] The drive shaft 2-8 is installed between the two side plates 2-2, and the stepped shafts at both ends are hinged to the horizontal connecting rod 3-1.

[0030] Linkage component 3 includes: horizontal link 3-1, connecting rod 3-2, pad block 3-3, and vertical link 3-4.

[0031] like Figure 4 As shown, one end of the horizontal connecting rod 3-1 is machined with a waist-shaped long slot hole, and the stepped shaft at the end of the drive shaft 2-8 is installed in the long slot hole to realize the rotation relative to the waist-shaped long slot and the movement within the waist-shaped long slot; the long slot of the horizontal connecting rod 3-1 can automatically compensate to avoid interference when the drive shaft 2-8 rotates around the axis of the fixed shaft 2-6.

[0032] The other end of the horizontal link 3-1 is hinged to the frame body 1. A pad 3-3 is installed between the horizontal link 3-1 and the frame body 1. The pad 3-3 can adjust the distance between the horizontal link 3-1 and the frame body 1, while avoiding direct contact between the horizontal link 3-1 and the frame body 1, which would result in excessive rotational resistance.

[0033] like Figure 5 As shown, horizontal connecting rods 3-1 are arranged in pairs and installed in parallel and symmetrically on both sides of the frame body 1.

[0034] The connecting rod 3-2 is positioned between the two horizontal connecting rods 3-1 and its two ends are rotatably connected to the horizontal connecting rods 3-1.

[0035] The vertical connecting rod 3-4 is installed in the middle of the connecting rod 3-2. The upper end is fixed to the connecting rod 3-2 by screws, and the lower end is connected to the brake component 4.

[0036] like Figure 6 and Figure 7 As shown, the brake component 4 includes: a fixing plate 4-1, a first connecting shaft 4-2, a bridge plate 4-3, a damper 4-4, a reinforcing sleeve 4-5, a second connecting shaft 4-6, and a connecting disc 4-7.

[0037] The fixing plate 4-1 is fixedly installed on the frame body 1 with screws.

[0038] The bridge plate 4-3 is hinged to the fixed plate 4-1 via the first connecting shaft 4-2.

[0039] The damper 4-4 is fixedly installed on the outside of the bridge plate 4-3 by screws.

[0040] The tendon sleeve 4-5 is fixedly installed on the lowest end face of the damper 4-4 to increase the friction with the ground.

[0041] A boss is machined on the inner end face of bridge plate 4-3, and an oblong hole is machined on the side of the boss. The boss of bridge plate 4-3 mates with the slot of connecting plate 4-7, and the side is hinged by the second connecting shaft 4-6. When connecting plate 4-7 moves up and down under the action of vertical connecting rod 3-4, the second connecting shaft 4-6 moves within the oblong hole of bridge plate 4-3 for automatic compensation, avoiding interference or jamming.

[0042] The structure consisting of the fixed plate 4-1, the first connecting shaft 4-2, the bridge plate 4-3, the damper 4-4, and the reinforcing sleeve 4-5 is arranged in four groups in four directions below the frame body 1.

[0043] The damper 4-4 has an automatic axial compensation function. When the applied force exceeds the limit, it automatically adjusts the extension length to prevent the frame 1 from being lifted up due to excessive downward force. When braking, the connecting plate 4-7 moves upward under the action of the vertical connecting rod 3-4, causing the bridge plate 4-3 to rotate around the fixed plate 4-1. This causes the damper 4-4 and the reinforcing sleeve 4-5 to make contact with the bottom surface, thereby achieving parking of the radar repair vehicle through friction.

[0044] The present invention discloses a parking device for a radar repair vehicle, the working principle of which is as follows:

[0045] 1. After moving the radar repair vehicle to the designated location, when the parking function is required, press down the grip lever 2-1. The handle component 2 will rotate around the fixed shaft 2-6, causing the drive shaft 2-8 to move upward. The upward movement of the drive shaft 2-8 will drive the horizontal connecting rod 3-1 to rotate around the axis of the pad 3-3, causing the vertical connecting rod 3-4 to move upward. The upward movement of the vertical connecting rod 3-4 will simultaneously cause one end of the four bridge plates 4-3 hinged to the connecting plate 4-7 to move upward. The simultaneous upward movement of one end of the four bridge plates 4-3 will cause the bridge plates 4-3 to rotate around the axis of the connecting shaft 4-2, thereby causing the other end of the bridge plates 4-3 to move downward, thus achieving contact and support between the reinforcing sleeve 4-5 and the ground. When the grip lever 2-1 is pressed down to the bottom, the drive shaft 2-8 is directly above the fixed shaft 2-6, the horizontal connecting rod 3-1 is in a horizontal state, and the vertical force between the handle component 2 and the connecting rod component 3 forms a self-locking mechanism. As the vertical connecting rod 3-4 moves upward, the damper 4-4 installed at the other end of the bridge plate 4-3 will gradually absorb the excess support stroke, so that the reinforcing sleeve 4-5 is always in contact with the ground and maintains the support balance.

[0046] 2. When the parking brake function needs to be canceled, simply lift the grip lever 2-1 upwards. The handle component 2 will rotate around the fixed shaft 2-6, thereby causing the drive shaft 2-8 to move downwards. The downward movement of the drive shaft 2-8 will cause the horizontal connecting rod 3-1 to rotate around the axis of the pad 3-3, thereby causing the vertical connecting rod 3-4 to move downwards. The downward movement of the vertical connecting rod 3-4 will simultaneously cause one end of each of the four bridge plates 4-3 hinged to the connecting plate 4-7 to move downwards, causing the other end of the bridge plates 4-3 to move upwards simultaneously. The damper 4-4 installed at the other end of the bridge plates 4-3 will gradually release the absorbed excess support stroke until the reinforcing sleeve 4-5 leaves the ground. After lifting the grip lever 2-1 to the highest position, the strong magnet 2-5 installed on the connecting plate 2-3 will be attracted to the frame 1, maintaining the parking brake canceled state, and the radar repair vehicle can be moved.
