Transfer box for high-precision electrical instruments

Abstract

The invention discloses a transfer box for high-precision electrical instruments, and relates to the technical field of transportation of high-precision instruments. In order to solve the problems that when an existing transportation device carries on a long-distance road surface or an uneven road surface, an internal instrument still bears large vibration, the fixing effect is poor due to the fact that a simple buckle or a manually-screwed pressing block is adopted as a fixing mode, clamping force is not easy to control, fixing is not firm if the clamping force is too small, and equipment is likely to be crushed if the clamping force is too large. Therefore, the problem that the transported instrument is damaged is solved. A plurality of springs are arranged between the upper surface of a fixed plate and the lower surface of a movable plate in the length direction, the lower surface of a limiting plate is connected with the inner bottom face of the box body through an elastic element, when the instrument is carried on a long distance or an uneven road surface, certain vibration can be filtered out through the elastic element, and the safety of the transported instrument is effectively guaranteed; damage to the instrument is avoided; and in addition, it can be guaranteed that the clamping force between the fixing plate and the limiting plate on the transported instrument is moderate. The device is suitable for transporting instruments.

Description

Technical Field

[0001] This invention relates to the field of transportation technology for high-precision instruments, and more specifically to a transfer box for high-precision electrical instruments. Background Technology

[0002] The inspection and maintenance of electrical automation equipment is a crucial link in ensuring production continuity. This process requires the use of various precision testing instruments and tools. These devices are often heavy, structurally complex, and expensive, and are highly sensitive to vibration and impact. Current technologies for handling and protecting such equipment typically suffer from the following drawbacks: First, inconvenient handling: most protective devices lack integrated, convenient moving mechanisms, or the moving mechanisms lack shock absorption capabilities. During long-distance transport or on uneven surfaces, the internal equipment still experiences significant vibration. Second, outdated fixing methods: simple clips or manually tightened blocks are commonly used, resulting in low fixing efficiency and difficulty in controlling clamping force. Too little force leads to insecure fixing, while too much force may damage the equipment. Third, limited shock absorption: existing shock absorption designs are mostly passive and typically only address bottom vibrations, offering poor buffering against multi-directional impacts and vibrations, making it difficult to effectively protect precision instruments. The published patent, "A Protective Device", with publication number CN210041023U, although it has basic shock-absorbing springs, its mobility and the degree of automation and intelligence of the clamping mechanism are insufficient, which cannot meet the needs of efficient and safe modern maintenance operations.

[0003] In summary, existing transport devices still subject internal instruments to significant vibrations during long-distance or uneven road transport. Furthermore, the securing methods are limited to simple clips or manually tightened blocks, resulting in poor fixation and difficulty in controlling the clamping force. Too little clamping force leads to insecure fixation, while too much force may damage the equipment, thus causing damage to the transported instruments. Summary of the Invention

[0004] This invention addresses the problem that existing transport devices still subject internal instruments to significant vibrations during long-distance or uneven road transport. Furthermore, the securing methods are limited to simple clips or manually tightened blocks, resulting in poor fixation and difficulty in controlling the clamping force. Too little clamping force leads to insecure fixation, while too much force may damage the equipment, thus causing damage to the transported instruments. Therefore, this invention proposes a transport box for high-precision electrical instruments.

[0005] The present invention provides a transfer box for high-precision electrical instruments, comprising a fixed support 3, a motor 4, a controller 5, a box body 6, a guide rail 7, a threaded rod 8, a moving plate 9, a fixed plate 10, a limiting plate 13, a spring 14, a slider 17, and a lead screw nut 18.

[0006] A fixed support 3 is provided on the middle of both sides of the upper surface of the housing 6, and a motor 4 is provided on each fixed support 3. The output shaft of the motor 4 passes through the through hole 15 on the fixed support 3 and the outer shell of the housing 6 in sequence, and is connected to one end of the threaded rod 8 through a coupling. A screw nut 18 is provided on the threaded rod 8. A guide rail 7 is provided on the middle of both sides of the interior of the housing 6 along the height direction, and a slider 17 is provided on each guide rail 7. The slider 17 is connected to one end of the outer surface of the corresponding screw nut 18. The other end of the outer surface of one screw nut 18 is connected to one end of the moving plate 9, and the other end of the outer surface of the other screw nut 18 is connected to the other end of the moving plate 9. The moving plate 9 is located inside the housing 6. A fixed plate 10 is provided below the moving plate 9. Multiple springs 14 are provided along the length direction between the upper surface of the fixed plate 10 and the lower surface of the moving plate 9.

The lower surface of the limiting plate 13 is connected to the inner bottom surface of the housing 6 through an elastic element. A controller 5 is provided at the center of the front of the housing 6.

[0007] Furthermore, a roller assembly 1 is provided at each of the four corners of the lower surface of the box 6;

[0008] Furthermore, a handle 2 is provided on the upper side of the box 6 along the width direction;

[0009] Furthermore, a rubber pad 11 is provided on the lower surface of the fixing plate 10 and the upper surface of the limiting plate 13 respectively;

[0010] Furthermore, a guide groove 12 is machined at each of the four corners inside the housing 6, and the right-angled part of the movable plate 9 is slidably connected with the guide groove 12.

[0011] Furthermore, a bearing 16 is provided between the outer surface of the output shaft of the motor 4 and the inner wall of the through hole 15 on the fixed support 3;

[0012] Furthermore, the controller 5 is a Siemens micro PLC controller, which is used to synchronously control the rotation direction and rotation speed of the two motors 4.

[0013] Furthermore, during use, the cabinet door of the housing 6 is opened, and the instrument to be transported is placed on the upper surface of the limiting plate 13 inside the housing. Then, the controller 5 controls the two motors 4 to rotate in the same direction and at the same speed, thereby driving the threaded rod 8 to rotate. At this time, the lead screw nut 18 moves downward along the threaded rod 8. In addition, a guide rail 7 is provided on the middle of both sides of the interior of the housing 6 along the height direction, and a slider 17 is provided on each guide rail 7. The slider 17 is connected to one end of the outer surface of the lead screw nut 18 at the corresponding position.

One end of the movable plate 9 is connected to the other end of the outer surface of the other screw nut 18, which is connected to the other end of the movable plate 9, so that the movable plate 9 moves downward at a uniform speed inside the box 6; in addition, a fixed plate 10 is provided below the movable plate 9, and multiple springs 14 are provided along the length direction between the upper surface of the fixed plate 10 and the lower surface of the movable plate 9, so that the fixed plate 10 contacts the outer surface of the instrument being transported, thereby generating a certain pre-tightening force on the instrument being transported, preventing the instrument being transported from moving up, down, left, and right inside the box 6, and completing the fixation of the instrument being transported inside the box 6;

[0014] Multiple springs 14 are provided along the length direction between the upper surface of the fixed plate 10 and the lower surface of the movable plate 9. The lower surface of the limiting plate 13 is connected to the inner bottom surface of the box 6 through elastic elements. When transported over long distances or on uneven roads, these elastic elements can filter out a certain amount of vibration, effectively ensuring the safety of the transported instrument and preventing damage to the instrument.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This invention overcomes the shortcomings of existing technologies by controlling two motors to rotate in the same direction and at the same speed through a controller, thereby driving the threaded rod to rotate. At this time, the lead screw nut moves downward along the threaded rod. Furthermore, a guide rail is provided on each of the two sides of the inner cavity along the height direction, and a slider is provided on each guide rail. The slider is connected to one end of the outer surface of the lead screw nut at the corresponding position. The other end of the outer surface of one lead screw nut is connected to one end of the moving plate, and the other end of the outer surface of the other lead screw nut is connected to the other end of the moving plate, thereby causing the moving plate to move downward at a uniform speed inside the cavity. A fixed plate is provided below the moving plate, and the upper surface of the fixed plate is aligned with the lower surface of the moving plate along the length... Multiple springs are installed along the direction to ensure that the fixing plate contacts the outer surface of the instrument being transported, thereby generating a certain pre-tightening force on the instrument and preventing it from moving around inside the box. This secures the instrument within the box. Furthermore, multiple springs are installed along the length of the fixed plate between the upper surface and the lower surface of the moving plate. The lower surface of the limiting plate is connected to the inner bottom of the box via elastic elements. When transporting the instrument over long distances or on uneven surfaces, these elastic elements filter out some vibrations, effectively ensuring the safety of the instrument and preventing damage. This also ensures that the clamping force between the fixed plate and the limiting plate on the instrument is moderate. Attached Figure Description
