Description

Technical Field

[0001] This utility model relates to the field of mass spectrometer technology, and in particular to a retractable heavy-duty platform for mass spectrometers. Background Technology

[0002] Ultra-high resolution quadrupole tandem Fourier transform mass spectrometry (FT-ICR-MS) is a cutting-edge instrument in scientific research, used to analyze the composition and structure of complex organic mixtures. It can separate minute changes in mass signal with extremely high mass resolution, thereby identifying the precise molecular formula and structure of trace components in the mixture.

[0040] The following is for reference. Figures 1-5 This describes a retractable heavy-duty mass spectrometer platform 100 according to an embodiment of the present invention.

[0041] like Figures 1 to 3 As shown, the retractable heavy-duty platform 100 for a mass spectrometer according to an embodiment of the present invention includes: a base 10, a support platform 20, a guide assembly 30, and a telescopic drive component 40. The base 10 includes two crossbeams 11, both of which extend along a first direction and are spaced apart in a second direction, which is perpendicular to the first direction and parallel to the horizontal plane. The support platform 20 is disposed between the two crossbeams 11 and is used to connect the mass spectrometer 200. A guide assembly 30 is provided between the support platform 20 and adjacent crossbeams 11. The telescopic drive component 40 is disposed on the base 10 and connected to the support platform 20 to drive the support platform 20 to move relative to the crossbeams 11 along the first direction under the guidance of the guide assembly 30.

[0042] The base 10 can refer to a supporting structure, and can be, but is not limited to, alloy steel, stainless steel, aluminum alloy, and composite materials, etc. The base 10 includes two crossbeams 11, the shape of which can be, but is not limited to, L-shaped plates and flat plates, etc. The two crossbeams 11 are spaced apart in a second direction, which is perpendicular to the first direction and parallel to the horizontal plane. (See reference...) Figure 3 For example, the first direction can refer to the front-back direction, and the second direction can refer to the left-right direction.

[0043] The support platform 20 can refer to the structure used to connect the crossbeam 11, and can be, but is not limited to, alloy steel, stainless steel, aluminum alloy, and composite materials, etc. The support platform 20 can be welded to the side cover 230 of the mass spectrometer 200 to ensure the reliability of the connection between the support platform 20 and the side cover 230 of the mass spectrometer 200.

[0044] The guide component 30 can refer to a structure that can move in a second direction.

[0045] The telescopic drive component 40 can refer to the component that drives the support platform 20 to move along the first direction. The connection method with the support platform 20 can be, but is not limited to, welding, bolting, riveting, etc.

[0046] According to the embodiment of the present invention, the retractable heavy-duty platform 100 for mass spectrometer drives the support platform 20 to move relative to the crossbeam 11 in a first direction under the guidance of the guide component 30 through the telescopic drive component 40, thereby driving the detector 210 and the side cover 230 to move relative to the superconducting magnet 220 in the first direction, realizing the free separation of the detector 210 and the superconducting magnet 220, and improving the reliability of the retractable heavy-duty platform 100 for mass spectrometer.

[0047] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 The guide assembly 30 includes a fixed rail 31, a first slide rail 32, and a second slide rail 33. The fixed rail 31 is disposed on the crossbeam 11 and extends along a first direction; the first slide rail 32 extends along the first direction and slides in cooperation with the fixed rail 31; the second slide rail 33 extends along the first direction and slides in cooperation with the first slide rail 32, and the second slide rail 33 is connected to the support platform 20.

[0048] The fixed rail 31 and the second slide rail 33 can be flat plates, and the first slide rail 32 can be an "I" shaped plate. The fixed rail 31, the first slide rail 32 and the second slide rail 33 have similar lengths in the first direction.

[0049] In the above technical solution, the design of fixed rail 31, first slide rail 32, and second slide rail 33 enables two-stage movement, increases the guiding stroke of the guiding component 30, expands the range within which the detector 210 and superconducting magnet 220 can be freely separated, and improves the reliability of the mass spectrometer's retractable heavy-duty platform 100. Simultaneously, it eliminates the need to lengthen the crossbeam 11, saving space. Furthermore, compared to the traditional single slide rail which must bear the entire load's friction and lateral torque, this design distributes the load through two-stage slide rails, reducing wear on individual sliding interfaces, extending service life, and further improving the reliability of the mass spectrometer's retractable heavy-duty platform 100.

[0050] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5The first slide rail 32 has grooves 32a at both ends in the second direction. The upper and lower groove walls of the grooves 32a are provided with first guide grooves 32b. The fixed rail 31 has second guide grooves 31a at both ends. The second slide rail 33 has third guide grooves 33a at both ends. Rolling elements 34 are provided between the first guide grooves 32b and the second guide grooves 31a, and between the first guide grooves 32b and the third guide grooves 33a.

[0051] Rolling element 34 can refer to a rolling component, which can be, but is not limited to, balls, rollers, and bearings, etc.

[0052] In the above technical solution, rolling elements 34 are provided between the first guide groove 32b and the second guide groove 31a, and between the first guide groove 32b and the third guide groove 33a. The rolling elements 34 can reciprocate along the first direction between the first guide groove 32b and the second guide groove 31a, and between the first guide groove 32b and the third guide groove 33a, converting the traditional sliding friction between the first slide rail 32 and the fixed rail 31 and the first slide rail 32 into rolling friction. This can reduce the driving force required for the telescopic drive element 40, and also enable the guide assembly 30 to achieve smooth and labor-saving telescopic movement, thereby allowing the detector 210 and the superconducting magnet 220 to separate freely.

[0053] In some embodiments of this utility model, the first guide groove 32b, the second guide groove 31a and the third guide groove 33a are semi-circular grooves, and the rolling element 34 is a ball.

[0054] In the above technical solution, the first guide groove 32b, the second guide groove 31a, and the third guide groove 33a are semi-circular grooves, and the rolling element 34 is a ball. The semi-circular groove and the ball form point contact, which can realize low-friction linear motion, ensuring that the first slide rail 32 and the fixed rail 31 can move relative to each other, thus improving the reliability of the guide assembly 30. At the same time, the semi-circular groove can be machined by standard milling cutter or grinding process, which can reduce costs.

[0055] In some embodiments of this utility model, reference is made to Figures 3 to 5 The first slide rail 32 is provided with a first limiting member 321 and a second limiting member 322. The first limiting member 321 and the second limiting member 322 are located at both ends of the first slide rail 32 in a second direction and are spaced apart along the first direction. The crossbeam 11 has a front side and a rear side arranged along the first direction. The first limiting member 321 can be limited and cooperated with the front end of the fixed rail 31, and the second limiting member 322 can be limited and cooperated with the rear end of the second slide rail 33.

[0056] The connection between the first limiting member 321 and the second limiting member 322 and the first slide rail 32 can be, but is not limited to, welding, bolting, riveting, etc. For example, the connection between the first limiting member 321 and the second limiting member 322 and the first slide rail 32 can be a bolt connection, which facilitates disassembly.

[0057] In the above technical solution, the design of the first limiting member 321 and the second limiting member 322 can prevent the second slide rail 33 from retracting excessively from the first slide rail 32, thereby avoiding the second slide rail 33 from falling off and improving the reliability of the guide assembly 30.

[0058] In some embodiments of this utility model, reference is made to Figure 3 The base 10 also includes a first bottom support 12 and a second bottom support 13. The first bottom support 12 and the second bottom support 13 are located at both ends of the crossbeam 11 in a first direction. The telescopic drive member 40 is located on the first bottom support 12 and is located on the lower side of the support platform 20. One end of the telescopic drive member 40 extends to near the second bottom support 13.

[0059] In the above technical solution, through the design of the first bottom support 12 and the second bottom support 13, the first bottom support 12 and the second bottom support 13 are respectively fixed to both ends of the crossbeam 11, forming a rectangular closed-loop frame with the two crossbeams 11, which improves the structural strength of the base 10 and further improves the reliability of the mass spectrometer retractable heavy-duty platform 100. At the same time, the telescopic drive component 40 is set on the first bottom support 12 and located on the lower side of the support platform 20. One end of the telescopic drive component 40 extends close to the second bottom support 13, which can reduce the length of the base 10 in the first direction, thereby reducing the volume of the mass spectrometer retractable heavy-duty platform 100.

[0060] In some embodiments of this utility model, reference is made to Figures 1 to 3 The mass spectrometer retractable heavy-duty platform 100 includes a connecting seat 50, which is located at one end of the first bottom support 12 away from the crossbeam 11 and is configured to connect a bracket 240 to a superconducting magnet 220.

[0061] The connection between the connector 50 and the support 240 of the superconducting magnet 220 can be, but is not limited to, welding, bolting, riveting, etc. For example, the connection between the connector 50 and the support 240 of the superconducting magnet 220 can be a bolt connection, which is convenient for disassembly.

[0062] In the above technical solution, the connecting seat 50 can be used to connect the base 10 to the support 240 of the superconducting magnet 220, so as to prevent the base 10 and the superconducting magnet 220 from moving relative to each other, and ensure that the end of the telescopic drive 40 close to the support 240 of the superconducting magnet 220 is relatively stationary, thereby improving the reliability of the telescopic heavy-duty platform 100 of the mass spectrometer.

[0063] In some embodiments of this utility model, reference is made to Figures 2 to 4 The telescopic drive component 40 is a motor push rod.

[0064] In the above technical solution, the telescopic drive component 40 is a motor push rod. The motor converts high-speed rotation into low-speed, high-torque output through a gear set or planetary reducer, driving the lead screw and nut mechanism to achieve linear motion, enabling the free separation of the detector 210 and the superconducting magnet 220. The motor push rod can be equipped with a Hall sensor or encoder to monitor displacement in real time, and, in conjunction with a PLC, achieve a positioning accuracy of ±0.1mm, improving the reliability of the mass spectrometer's telescopic heavy-duty platform 100. Simultaneously, the motor push rod has a simple structure, reducing cost, maintenance difficulty, and space occupation.

The receiving groove 20a includes a first groove 20b, a second groove 20c and a third groove 20d. The first groove 20b and the second groove 20c extend along a first direction and are spaced apart in a second direction. The third groove 20d is located at one end of the first groove 20b and the second groove 20c near the first bottom support 12 and connects the first groove 20b and the second groove 20c.

[0066] In the above technical solution, through the design of the first groove 20b, the second groove 20c and the third groove 20d, the internal space can be used to place components such as wires, thereby improving the space utilization rate of the mass spectrometer's retractable heavy-duty platform 100.

[0067] In some embodiments of this utility model, reference is made to Figure 2 At least two support limiting members 21 are provided at both ends of the second direction and both ends of the first direction of the support platform 20.
