Description

Technical Field

[0001] This utility model relates to the field of inspection vehicles, specifically a base for an inspection vehicle. Background Technology

[0002] In industrial plants, warehouse parks and other settings, inspection vehicles are important tools for achieving automated patrols and equipment monitoring. The base, as the core component that supports the vehicle body and the driving system, directly affects the driving stability and service life of the inspection vehicle. Especially in inspection environments with uneven road surfaces (such as those with gravel or depressions), the cushioning and shock absorption performance, driving efficiency and structural protection capabilities of the base become the key to ensuring the continuous operation of inspections. Currently, the shock absorption structure design of most patrol vehicle bases has defects: although equipped with buffer components such as springs and shock absorbers, corresponding limiting structures are not set. When the patrol vehicle travels over bumpy roads, the shock absorption components are prone to excessive compression or stretching beyond their effective working stroke, which not only reduces the buffering effect on the wheels (such as increasing the amplitude of vehicle body bumps), but may also cause deformation and damage to the shock absorption structure itself. At the same time, the support structure of the base (such as the bracket connecting the wheels and the base) lacks movement restraint. When the vehicle stops suddenly, turns, or passes over obstacles, the support structure is prone to excessive swaying due to inertia, colliding with the main body of the base. Long-term collisions will cause loosening of the connection points, wear of components, and in severe cases, even wheel misalignment, affecting driving safety. In terms of driving efficiency, traditional inspection vehicles mostly use a "single motor + transmission rod" to drive multiple wheels. When power is transmitted through the transmission components, energy loss is easily generated (such as gear meshing gaps and belt slippage). Especially when climbing hills or on muddy roads, a single wheel may not have enough power. Although the design of using an independent geared motor to drive a single wheel is gradually being adopted, the existing base lacks compatibility for motor installation and fixation. The connection between the motor and the base is too rigid, and vibration during driving can easily cause the motor bolts to loosen, which reduces driving stability. In addition, the base lacks wear resistance and compression protection: the bottom of the base and the exposed parts of the support structure are mostly made of ordinary steel, and key components such as the connecting shaft between the wheels and the base lack protective sleeves. The support structure is prone to contact or collision with the base, affecting the service life of the support structure or the base.

[0003] The lack of shock absorbers, the vulnerability of the support structure to collisions, and the insufficient protective performance have become important factors restricting the adaptability of inspection vehicles to complex road surfaces. Especially for inspection scenarios that require long-term and high-frequency operations, the wear and tear of the base components will lead to increased maintenance frequency and affect the continuity of inspection tasks. Therefore, there is an urgent need for an optimized inspection vehicle base that can solve the above problems by adding shock absorbers, strengthening drive stability, and improving the protective structure, thereby improving the driving reliability and service life of the inspection vehicle. Utility Model Content

[0004] The purpose of this invention is to provide a base for an inspection vehicle to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a base for an inspection vehicle, comprising a base frame, connecting frames fixedly installed around the base frame, and fixed seats installed around the base frame and below the connecting frames via bolts. An mounting frame is hinged to the outside of the fixed seats. A geared motor is mounted on one side of the mounting frame via a clamping frame, and a tire is fixedly mounted on one side of the geared motor via a coupling. Connecting plates are fixedly connected to the top of the mounting frame and near both sides. A buffer is installed between the connecting frame and the connecting plates. Two sets of limiting members are installed inside the connecting frame. Two sets of protective members are installed around the bottom of the base frame near the corners. The protective members are used to prevent the mounting frame from excessively rotating and colliding with the base frame.

[0006] Preferably, the buffer includes a notch on one side of the connecting frame, a first bolt rod passing through the inner side of the notch, a second bolt rod passing through the two connecting plates, a shock absorber rod hinged to the outer side of the first bolt rod and the second bolt rod, a shock absorber spring being fitted on the outer side of the shock absorber rod, and both the first bolt rod and the second bolt rod being installed and fixed by nuts.

[0007] Preferably, the limiting component includes two second springs fitted on the outside of the first bolt rod, with a fixing ring fixedly connected to one end of each second spring. The fixing ring is rotatably connected to the rotating ring through a connecting part and does not detach.

[0008] Preferably, the protective component includes two fixing plates, which are welded to the bottom perimeter of the base frame and near the corners, and a protective frame is fixedly connected to one side of the fixing plate.

[0009] Preferably, four guide rods arranged in a circle are fixedly connected to the other side of the connecting frame, and the ends of the guide rods are limited by screwed nuts.

[0010] Preferably, the inner side of the protective frame is fixedly connected with a plurality of evenly arranged spring pieces.

[0011] Preferably, two wear-resistant strips are fixedly connected to the other side of the mounting bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The base frame is a rectangular aluminum frame. The fixed base and the mounting frame are hinged. The buffer components installed between the mounting frame and the connecting frame can dampen the vibration of the clamping frame. This buffers the vibration amplitude of the geared motor inside the clamping frame supporting the tire. The geared motor can drive the tire to rotate independently. The limiting components can block and limit the buffer components to prevent them from shifting or shaking. The protective components can protect the mounting frame from collisions to prevent the mounting frame from moving excessively and colliding with the base, causing damage.

[0013] 2. The first bolt rod passes through the notch and inserts into one end of the shock absorber rod. The second bolt rod passes through the connecting plate and the shock absorber rod. The two ends of the shock absorber rod are hinged to the first bolt rod and the second bolt rod respectively. When vibration occurs, the tire drives the mounting frame to rotate around the fixed seat through the clamp frame. The shock absorber rod and the shock absorber spring support one end of the mounting frame, reducing the amplitude of tire vibration and improving the smoothness and stability of the base frame moving through the four tires.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] Please refer to Figure 1-4As shown, this utility model provides a base for an inspection vehicle, including a base frame 1. Connecting frames 2 are fixedly installed around the base frame 1. Fixed seats 3 are installed around the base frame 1 and below the connecting frames 2 by bolts. Mounting frames 4 are hinged to the outside of the fixed seats 3. A geared motor 6 is installed on one side of the mounting frame 4 by a clamping frame 5. A tire 7 is fixedly installed on one side of the geared motor 6 by a coupling. Connecting plates 8 are fixedly connected to the top of the mounting frame 4 and near both sides. A buffer is installed between the connecting frames 2 and the connecting plates 8. Two sets of limiting members are installed on the inner side of the connecting frames 2. Two sets of protective members are installed around the bottom of the base frame 1 and near the corners. The protective members are used to prevent the mounting frame 4 from rotating excessively and colliding with the base frame 1.

[0018] It should be added that the base frame 1 is a rectangular aluminum frame, the fixed seat 3 is hinged to the mounting frame 4, and the buffer component installed between the mounting frame 4 and the connecting frame 2 can dampen the vibration of the clamping frame 5, so as to buffer the vibration amplitude of the tire 7 supported by the geared motor 6 inside the clamping frame 5. The geared motor 6 can drive the tire 7 to rotate independently. The limiting component can block and limit the buffer component to prevent the buffer component from shifting or shaking. The protective component can protect the mounting frame 4 from collision and damage caused by excessive movement of the mounting frame 4.

[0019] Specifically, the buffer includes a notch 9 on one side of the connecting frame 2, a first bolt rod 10 passing through the inside of the notch 9, a second bolt rod 11 passing through between the two connecting plates 8, a shock absorber rod 12 hinged to the outside of the first bolt rod 10 and the second bolt rod 11, and a shock absorber spring 13 fitted on the outside of the shock absorber rod 12. The first bolt rod 10 and the second bolt rod 11 are both installed and fixed by nuts.

[0020] The first bolt rod 10 passes through the notch 9 and inserts into one end of the shock absorber rod 12. The second bolt rod 11 passes through the connecting plate 8 and the shock absorber rod 12. The two ends of the shock absorber rod 12 are hinged to the first bolt rod 10 and the second bolt rod 11 respectively. When vibration occurs, the tire 7 drives the mounting frame 4 to rotate around the fixed seat 3 through the clamp frame 5. The shock absorber rod 12 and the shock absorber spring 13 support one end of the mounting frame 4, reducing the amplitude of the tire 7's vibration and improving the smoothness and stability of the base frame 1 moving through the four tires 7.

[0021] More specifically, the limiting component includes two second springs 14 fitted on the outside of the first bolt rod 10. One end of the second spring 14 is fixedly connected to a fixing ring 15. The fixing ring 15 is rotatably connected to the rotating ring 17 through the connecting part 16 and does not detach. The other side of the connecting frame 2 is fixedly connected to four guide rods 20 arranged in a circle. The ends of the guide rods 20 are limited by screwed nuts.

[0022] It should be added that the two ends of the second spring 14 are fixedly connected to the fixed ring 15 and the notch 9 respectively. The second spring 14 can push the rotating ring 17 to fit against the outside of the shock absorber rod 12 through the fixed ring 15. The rotating ring 17 rotates inside the fixed ring 15 through the connecting part 16 and does not detach. The four guide rods 20 guide and support the fixed ring 15. The guide rods 20 are limited by nuts screwed to their ends.

[0023] Furthermore, the protective component includes two fixing plates 18, which are welded to the bottom perimeter of the base frame 1 and near the corners. A protective frame 19 is fixedly connected to one side of the fixing plate 18, and multiple evenly arranged spring pieces 21 are fixedly connected to the inner side of the protective frame 19. Two wear-resistant strips 22 are fixedly connected to the other side of the mounting frame 4.

[0024] The fixed plate 18 has a triangular cross section. The protective frame 19 on one side of the fixed plate 18 is made of rubber. Multiple spring pieces 21 can support the protective frame 19 and increase its compressive strength. The wear-resistant strip 22 on one side of the mounting frame 4 fits and buffers the protective frame 19, preventing the mounting frame 4 from colliding with or being damaged by the base frame 1.

[0025] Working principle: First, the geared motor 6 is started, which drives the tire 7 to move the base frame 1. When vibration occurs, the tire 7 drives the mounting frame 4 to rotate around the fixed seat 3 through the clamping frame 5. At this time, the shock absorber rod 12 and the shock absorber spring 13 support one end of the mounting frame 4 to reduce the amplitude of the tire 7 vibration. At the same time, the second spring 14 pushes the rotating ring 17 to fit against the outside of the shock absorber rod 12 through the fixed ring 15. Meanwhile, the rotating ring 17 rotates within the fixed ring 15 through the connecting part 16 and does not detach. At the same time, the four guide rods 20 guide and support the fixed ring 15. The mounting frame 4 rotates around the fixed seat 3. Then, the wear-resistant strip 22 on one side of the mounting frame 4 fits against the protective frame 19. At the same time, multiple spring pieces 21 support the protective frame 19.
