Description

Technical Field

[0001] This utility model relates to the field of data acquisition equipment technology, specifically a data acquisition device that is easy to move. Background Technology

[0002] In today's digital age, data acquisition equipment is widely used in many fields such as industrial production monitoring, environmental data collection, and scientific research data acquisition. As various industries continue to increase their demands for data accuracy and real-time performance, the performance of data acquisition equipment faces even greater challenges.

[0003] According to announcement number CN 211083299 U, a mobile data acquisition device that is easy to move includes a support plate, a support frame fixedly connected to the bottom of the support plate, a motor fixedly connected to the support frame, and a drive gear fixedly connected to the output shaft of the motor.

[0004] This device uses a motor. When the motor is started, it drives a rotating shaft, which in turn drives a drive gear. The drive gear, via a chain, drives a driven gear, which in turn drives the rotating shaft, which in turn drives rollers. This makes the data acquisition equipment easier to move. Powered by electricity, it saves manpower and improves work efficiency. A first spring and shock-absorbing components reduce vibrations during movement, cushioning the equipment and preventing damage. However, the device lacks height adjustment functionality, making it unsuitable for data acquisition at different heights. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a data acquisition device that is easy to move, including a base, universal wheels that are symmetrically and fixedly connected to the bottom of the base, a push handle that is fixedly connected to the right side of the top of the base, a limit lifting mechanism that is provided on the top of the base, a shock absorption and buffer mechanism that is provided on the top of the limit lifting mechanism, a fixed seat that is provided on the top of the shock absorption and buffer mechanism, and a data acquisition device that is fixedly connected to the top of the fixed seat.

[0007] The limiting lifting mechanism includes a fixed cover, which is fixedly connected to the top of the base. The fixed base has heat dissipation holes on both the front and rear sides. A fixed plate is fixedly connected to the top of the inner wall of the fixed cover. A servo motor is fixedly connected to the front of the fixed plate.

[0009] Preferably, the top of the lifting frame has a hole that matches the limiting rod, and the lifting plate is slidably connected to the surface of the limiting rod through the hole. The limiting rod limits the lifting plate, so that the lifting plate moves up and down as the screw rotates.

[0010] Preferably, the top of the base has a groove that matches the lifting column, and the surface of the lifting column is slidably connected to the groove, with the limiting pressure plate located below the base.

[0011] Preferably, the shock absorption and buffer mechanism includes a fixed frame, which is symmetrically fixedly connected to the top of the fixed cover in the front, back, left and right directions. Four fixed frames are symmetrically arranged with sliding rods on the top left and right sides. A fixed ring is fixedly connected to the surface of the sliding rod near the bottom.

[0015] Preferably, the shock-absorbing spring is model D001.

[0016] Compared with the prior art, this utility model provides a data acquisition device that is easy to move, and has the following beneficial effects:

[0017] 1. This easily movable data acquisition device employs a servo motor-driven worm gear transmission for its limit lifting mechanism, which in turn rotates the screw, causing the lifting frame to slide up and down along the limit rod, thus achieving precise adjustment of the data acquisition device's height. This structure not only offers stable transmission and excellent self-locking performance but also meets the data acquisition needs of different heights and scenarios, such as ground data acquisition and high-altitude equipment data monitoring, making it widely applicable.

[0018] 2. This portable data acquisition device features a shock absorption mechanism in which sliding rods, fixing rings, shock-absorbing springs, and damping rods work together to form a multi-stage shock absorption system. When the device encounters bumps or vibrations during movement, the shock-absorbing springs absorb most of the impact force, while the damping rods consume energy to suppress the spring's rebound oscillation, effectively reducing the impact of vibration on the data acquisition unit, protecting internal precision components from damage, extending the device's service life, and ensuring the accuracy and stability of data acquisition.

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Please see Figure 1-4 This utility model provides a technical solution: a data acquisition device that is easy to move, including a base 1, with universal wheels 2 fixedly connected symmetrically to the bottom of the base 1 in the front, back, left and right directions, a push handle 3 fixedly connected to the top right side of the base 1, a limit lifting mechanism 4 provided on the top of the base 1, a shock absorption and buffer mechanism 5 provided on the top of the limit lifting mechanism 4, a fixed seat 6 provided on the top of the shock absorption and buffer mechanism 5, and a data acquisition device 7 fixedly connected to the top of the fixed seat 6.

[0032] The limiting lifting mechanism 4 includes a fixed cover 41, which is fixedly connected to the top of the base 1. The fixed base 6 has heat dissipation holes 42 on both the front and rear sides. A fixed plate 43 is fixedly connected to the top of the inner wall of the fixed cover 41. A servo motor 44 is fixedly connected to the front of the fixed plate 43. A worm gear 45 is fixedly connected to the output end of the servo motor 44. A screw 46 is rotatably connected to the top of the inner wall of the fixed cover 41. A worm wheel 47 is fixedly connected to the surface of the screw 46 near the top. A lifting frame 48 is threadedly connected to the surface of the screw 46. Limiting rods 49 are symmetrically fixedly connected to the top of the fixed cover 41. Lifting columns 411 are symmetrically fixedly connected to the bottom of the lifting frame 48. Limiting pressure plates 412 are fixedly connected to the bottom of the four lifting columns 411.

[0033] The bottom end of the screw 46 is rotatably connected to the top of the base 1, the worm 45 meshes with the worm wheel 47, and the bottom end of the limiting rod 49 is fixedly connected to the top of the base 1.

[0034] The top of the lifting frame 48 has a hole that matches the limiting rod 49, and the lifting plate is slidably connected to the surface of the limiting rod 49 through the hole. The limiting rod 49 limits the lifting plate, so that the lifting plate moves up and down with the rotation of the screw 46.

[0035] The top of the base 1 has a groove that matches the lifting column 411, and the surface of the lifting column 411 is slidably connected to the groove. The limiting pressure plate 412 is located below the base 1.

[0036] Example 2

[0037] Please see Figure 5-6 Furthermore, based on Example 1, a shock-absorbing and buffering mechanism 5 is obtained.

[0038] The shock absorption and buffer mechanism 5 includes a fixed frame 51, which is symmetrically fixed to the top of the fixed cover 41. The four fixed frames 51 are symmetrically arranged with slide rods 52 on the top left and right. A fixed ring 53 is fixedly connected to the surface of the slide rod 52 near the bottom. A shock-absorbing spring 54 is fixedly connected to the bottom of the fixed ring 53. A mounting plate 55 is fixedly connected to the top of the slide rod 52. A damping rod 56 is fixedly connected to the bottom of the mounting plate 55.

[0039] The top of the four fixing brackets 51 has holes that match the sliding rods 52, and the sliding rods 52 are connected to the holes by sliding up and down through the surface of the sliding rods 52.

[0040] The bottom end of the shock-absorbing spring 54 is fixedly connected to the bottom of the inner wall of the fixing frame 51, the bottom end of the damping rod 56 is fixedly connected to the bottom of the inner wall of the fixing frame 51, and the top of the mounting plate 55 is fixedly connected to the bottom of the fixing seat 6.

[0041] In actual operation, when this device is in use, the casters 2 at the bottom of the device can rotate freely 360 degrees. When the operator pushes the push handle 3 on the top right, the casters 2 roll under force, allowing the device to move easily in different directions and on different ground surfaces, quickly reaching the data acquisition work location. When the height of the data acquisition unit 7 needs to be adjusted, the servo motor 44 is powered on and starts, its output driving the worm gear 45 to rotate. Since the worm gear 45 meshes with the worm wheel 47, the rotation of the worm gear 45 drives the worm wheel 47 to rotate, which in turn causes the screw 46 to rotate. When the screw 46 rotates, the lifting frame 48, which is threaded to it, is limited by the limiting rod 49 and moves up and down linearly along the limiting rod 49. At the same time, the lifting column 411 at the bottom of the lifting frame 48 slides in the groove at the top of the base 1, further ensuring the stability of the lifting process. The descent of the lifting frame 48 causes the entire device to move upward, bringing the fixed base 6 and the data acquisition unit 7 to a suitable height to meet the data acquisition needs of different scenarios. Furthermore, once the equipment is moved to the designated position, the servo motor 44 can be controlled to lower the lifting column 411 and the limiting plate 412, pressing it firmly against the ground to fix the equipment and enhance its stability during operation. If bumps or vibrations occur during equipment movement, the fixing seat 6 will cause the mounting plate 55 to shift. At this time, the slide rod 52 slides up and down within the hole at the top of the fixing frame 51, and the damping spring 54 below the fixing ring 53 is compressed or stretched, converting some of the vibration energy into the elastic potential energy of the damping spring 54, thus providing initial vibration damping. Simultaneously, the damping rod 56 dissipates vibration energy through the movement of its internal damping medium, suppressing the rebound oscillation of the damping spring 54, further reducing the impact of vibration on the data acquisition unit 7. Through the coordinated work of both, vibration transmission is effectively reduced, protecting the precision components inside the data acquisition unit 7.
