Detailed Implementation

[0040] The core of this application is to provide an equipment maintenance device to improve the convenience of maintaining a copier-printer multifunction printer.

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] In related fields, especially in the main control room of a nuclear power plant, to ensure the multifunction printer 60 meets seismic resistance requirements, it is typically placed in a multifunction printer cabinet 50 to prevent uncontrollable displacement under seismic loads that could damage other equipment. Because the multifunction printer 60 is heavy and placed on a tray 51 of considerable height, it is difficult to move it manually during maintenance. Furthermore, due to limited space, it is not possible to install ramps to assist in the entry and exit of the multifunction printer 60.

[0043] Therefore, such as Figure 1 As shown in the figure, this application discloses an equipment maintenance device, including a support component 10, a moving device 20, an adjustment mechanism 30, and a handrail 40. The adjustment mechanism 30 can realize the lifting and lowering of the platform 12, compensate for manufacturing and installation errors of the copier-printer cabinet 50, and ensure that the platform 12 and the tray 51 inside the copier-printer cabinet 50 are aligned without any height difference, thereby ensuring that the copier-printer 60 can be smoothly pulled out and pushed in, and improving the convenience of maintaining the copier-printer 60.

[0044] The following will combine Figures 1 to 13 The equipment maintenance device disclosed in the embodiments of this application will be explained and described in detail.

[0045] Among them, such as Figures 1 to 3 As shown, the support assembly 10 may include a chassis 11 and a platform 12 movably mounted on the chassis 11. During transportation, equipment such as the multifunction printer 60 can be placed on the platform 12, and the support assembly 10 can be moved by the moving device 20 mounted on the chassis 11, thereby realizing the transportation and maintenance of equipment such as the multifunction printer 60. At the same time, the handrail 40 detachably mounted on the support assembly 10 facilitates the movement of the multifunction printer 60, and the equipment maintenance device can be placed together with the multifunction printer 60 in the multifunction printer cabinet 50 by removing the handrail 40.

[0046] To facilitate the pulling out or pushing of devices such as the multifunction printer 60 from the tray 51 inside the multifunction printer cabinet 50, such as... Figure 1As shown, the platform 12 can be raised and lowered by the adjustment mechanism 30 set on the chassis 11 so that the platform 12 is flush with the tray 51 inside the copier and printer cabinet 50. This compensates for manufacturing and installation errors of the copier and printer cabinet 50 and ensures that there is no height difference between the platform 12 and the tray 51 inside the copier and printer cabinet 50, so that the copier and printer 60 can be pulled out and pushed in smoothly, thereby improving the convenience of maintenance of the copier and printer 60.

[0047] In some embodiments, such as Figure 4 As shown, the adjustment mechanism 30 may include a lifting bracket 31 and an adjusting screw 32 capable of driving the lifting bracket 31 to rise and fall. The lifting bracket 31 may include a pair of first connecting rods 311 and second connecting rods 312, which are hinged together by a connecting shaft 313. For ease of understanding, the two ends of the first connecting rod 311 are defined as the first end and the second end, and the two ends of the second connecting rod 312 are also defined as the first end and the second end, respectively. The first end of the first connecting rod 311 can be connected to the chassis 11, and the second end of the first connecting rod 311 can be connected to the platform 12. The first end of the second connecting rod 312 can be connected to the platform 12, and the second end of the second connecting rod 312 can be connected to the chassis 11. The first ends of the first connecting rod 311 and the first ends of the second connecting rod 312 are located on the same side, so that the first connecting rod 311 and the second connecting rod 312 are arranged crosswise. Meanwhile, the first ends of the two first connecting rods 311 can be hinged to each other via the first connecting rod 3112, and the first ends of the two second connecting rods 312 can be hinged to each other via the second connecting rod 3122. The adjusting screw 32 can be connected to the first connecting rod 3112 between the first ends of the two first connecting rods 311 via a Y-shaped bracket, so that by rotating the adjusting screw 32, the first ends of the two first connecting rods 311 can be moved toward or away from the second ends of the first connecting rods 311, thereby enabling the second ends of the first connecting rods 311 and the first ends of the second connecting rods 312 to drive the platform 12 to perform lifting and lowering actions.

[0048] In some embodiments, such as Figure 4 As shown, the first end of the first link 311 may be provided with a first guide wheel 3111, and the first end of the second link 312 may be provided with a second guide wheel 3121, and as... Figure 5 and Figure 7 As shown, the chassis 11 is provided with a first guide groove 111 that mates with the first guide wheel 3111, and the platform 12 is provided with a second guide groove 121 that mates with the second guide wheel 3121. This allows the first guide wheel 3111 and the second guide wheel 3121 to roll within the first guide groove 111 and the second guide groove 121 respectively when the second end of the first connecting rod 311 and the first end of the second connecting rod 312 drive the platform 12 to rise or fall. This reduces friction and ensures the stability of the platform 12's lifting and lowering. Figure 11 As shown.

[0049] In some embodiments, such as Figure 4 As shown, a first ear plate 3113, which can be hinged to the first end of the first connecting rod 3111, is fixed on the side of the first connecting rod 3112 near the second end of the first connecting rod 311. Meanwhile, as... Figure 7 As shown, a second hinge seat 126 is provided on the platform 12, which can be hinged to the second end of the first connecting rod 311. First guide wheels 3111 are rotatably disposed at both ends of the first connecting rod 3112. Four first guide wheels 3111 can be used, and the four first guide wheels 3111 are symmetrically disposed at both ends of the first connecting rod 3112. Figure 5 and Figure 8 As shown, there are two first guide grooves 111 that are adapted to the first guide wheel 3111, and the first guide grooves 111 can adopt a U-shaped structure. The openings of the two first guide grooves 111 are positioned opposite each other on both sides of the bottom of the chassis 11, so that when the second end of the first connecting rod 311 and the first end of the second connecting rod 312 drive the platform 12 to rise and fall, the first guide wheel 3111 can roll within the corresponding first guide groove 111, thereby reducing friction and ensuring the stability of the platform 12's lifting and lowering. Figure 11 As shown.

[0050] In some embodiments, such as Figure 4 As shown, a second lug 3123, which can be hinged to the first end of the second connecting rod 3122, is fixed on the side of the second connecting rod 3122 near the second end of the second connecting rod 3122. Meanwhile, as... Figure 5 As shown, a first hinge seat 116 is provided on the chassis 11, which can be hinged to the second end of the second connecting rod 312. Second guide wheels 3121 are rotatably disposed at both ends of the second connecting rod 3122. Four second guide wheels 3121 can be used, and the four second guide wheels 3121 are symmetrically disposed at both ends of the second connecting rod 3122. Figure 7 As shown, there are two second guide grooves 121 that are adapted to the second guide wheels 3121, and the second guide grooves 121 can adopt a U-shaped structure. The openings of the two second guide grooves 121 are positioned opposite each other on both sides of the bottom of the platform 12, so that when the second end of the first connecting rod 311 and the first end of the second connecting rod 312 drive the platform 12 to rise and fall, the second guide wheels 3121 can roll within the corresponding second guide grooves 121, thereby reducing friction and ensuring the stability of the platform 12's lifting and lowering. Figure 11 As shown.

[0051] In some embodiments, such as Figure 5 and Figure 8As shown, an adjustment interface 115 that mates with the adjustment screw 32 can be provided at the bottom of the chassis 11. The adjustment interface 115 may have an internal thread. By rotating the adjustment screw 32, the adjustment screw 32 engages with the internal thread of the adjustment interface 115, thereby moving the adjustment screw 32. This allows the first ends of the two first connecting rods 311 to move towards or away from the second ends of the first connecting rods 311, thus enabling the second ends of the first connecting rods 311 and the first ends of the second connecting rods 312 to drive the platform 12 to perform lifting and lowering actions.

[0052] In some embodiments, such as Figure 4 As shown, one or more return springs 33 may be provided between the first end of the first connecting rod 311 and the chassis 11, that is, one, two or more return springs 33 may be used. For example, Figure 8 As shown, one end of the reset spring 33 is connected to the first connecting rod 3112 between the two first connecting rods 311, and the other end of the reset spring 33 is connected to the chassis 11. Thus, the platform 12 can be rapidly lowered by the elastic force of the reset spring 33, while improving the overall stability of the adjustment mechanism 30.

[0053] like Figure 11 As shown, for ease of understanding, the lengths of the first link 311 and the second link 312 are defined as S, the moving distance of the first guide wheel 3111 and the second guide wheel 3121 is defined as L, and the initial height of the platform 12 is defined as H1, and the lifting height of the platform 12 is defined as H2. Based on geometric relationships, we can obtain... It should be noted that the force F is generated by the adjusting screw 32 of the rotary adjusting mechanism 30.

[0054] For example, the length S of the first link 311 and the second link 312 is 600mm, the initial height H1 of the platform 12 is 120mm, and the lifting height H2 of the platform 12 is 170mm, according to the formula... We can obtain L≈12.47mm, that is, the first guide wheel 3111 and the second guide wheel 3121 moved 12.47mm in the direction of force F, and the height increased by 50mm.

[0055] In some embodiments, such as Figure 9 As shown, the handrail 40 may have two parallel connecting arms 41, and one or more reinforcing rods may be connected between the two connecting arms 41, i.e., there may be one, two, or more reinforcing rods, to improve the overall strength and stability of the handrail 40. Meanwhile, as... Figure 9 and Figure 10 As shown, the connecting arm 41 has a plug-in end 411 at its end, and a ball lock 4111 can be provided on the outer peripheral surface of the plug-in end 411, and as... Figure 5As shown, a handrail interface 112 that mates with the connecting arm 41 is provided on the chassis 11. When the insertion end 411 of the handrail 40 is inserted into the handrail interface 112, the ball lock 4111 can retract into the insertion end 411 until the insertion end 411 of the handrail 40 is fully inserted. Then, the ball lock 4111 pops out and mates with the end face of the handrail interface 112 to lock the handrail 40.

[0056] In some embodiments, such as Figure 10 As shown, symmetrically arranged oblong holes 4112 are provided on the outer peripheral surface of the plug-in end 411, and the oblong holes 4112 can extend axially along the plug-in end 411. Simultaneously, a reset pin 4113 is inserted at the position of the oblong hole 4112, and a reset elastic element 4114 is provided inside the plug-in end 411. One end of the reset elastic element 4114 abuts against the reset pin 4113, and the other end of the reset elastic element 4114 abuts against the plug-in end 411, so that when the ball lock 4111 retracts, the reset pin 4113 compresses the reset elastic element 4114, and the reset pin 4113 moves from the side of the oblong hole 4112 near the ball lock 4111 to the side of the oblong hole 4112 away from the ball lock 4111. Meanwhile, as... Figure 5 As shown, a slot 1121 for engaging the reset pin 4113 is provided on the peripheral wall of the handrail interface 112. When disassembling the handrail 40, simply press the ball lock 4111. The reset pin 4113 compresses the reset elastic element 4114, and the reset pin 4113 moves from the side of the waist-shaped hole 4112 near the ball lock 4111 to the side of the waist-shaped hole 4112 away from the ball lock 4111. At this time, the insertion end 411 of the handrail 40 can be easily pulled out under the elastic force of the reset elastic element 4114, thereby achieving the purpose of quickly disassembling the handrail 40.

[0057] In some embodiments, such as Figure 6 As shown, the platform 12 may have a support surface 122 for supporting equipment, and a receiving groove is provided on the support surface 122 for placing a tool for tightening the adjusting screw 32. A movable cover plate 123 may be provided at the opening of the receiving groove, and the cover plate 123 may adopt a rotating door structure, that is, the cover plate 123 may rotate along the central axis connected to the edge of the opening of the receiving groove, thereby realizing the opening and closing of the cover plate 123. When the cover plate 123 is in the closed state, the cover plate 123 can be located on the same plane as the support surface 122, thereby avoiding interference with the placement of the equipment on the support surface 122.

[0058] In some embodiments, such as Figure 7As shown, in order to ensure the stability of the platform 12 during lifting, multiple guide rods 124 can be provided on the side of the platform 12 away from the support surface 122. That is, there can be two, three, four or more guide rods 124. The chassis 11 is provided with guide holes 114 that are adapted to the guide rods 124. Thus, the guide rods 124 can slide and cooperate with the guide holes 114 to provide guidance for the lifting of the platform 12 and ensure the stability of the platform 12 during lifting.

[0059] In some embodiments, such as Figure 7 As shown, multiple buffer elements 125 can be provided on the side of the platform 12 away from the support surface 122, that is, there can be two, three, four or more buffer elements 125. When the platform 12 is lowered to its lowest point, it can contact the chassis 11 through the buffer elements 125, thereby achieving the effect of buffering and shock absorption. The buffer elements 125 can be rubber pads, etc., which are not limited here.

[0060] In some embodiments, such as Figure 5 As shown, multiple support screws 113 can be provided on the chassis 11, that is, two, three, four or more support screws 113 can be used. When the platform 12 is raised to a certain height, the support screws 113 can be rotated to make the support screws 113 abut against the platform 12, thereby achieving a double support effect for the platform 12, ensuring that the platform 12 will not suddenly drop and cause danger even after the adjustment structure 30 fails.

[0061] In some embodiments, such as Figure 6 As shown, multiple reserved holes can also be provided on both sides of the platform 12, which facilitates the installation of auxiliary parts such as guardrails, making the equipment maintenance device applicable to multiple scenarios and improving the applicability of the equipment maintenance device.

[0062] In some embodiments, such as Figure 5 As shown, the moving device 20 may include a pair of directional wheels 21 and locking casters 22. The directional wheels 21 and casters 22 may be located at the bottom of both ends of the chassis 11, with the casters 22 located at the end of the chassis 11 closest to the handle 40. The locking casters 22 ensure that the equipment maintenance device is prevented from moving during maintenance, thus ensuring a stable and safe maintenance process.

[0063] In some embodiments, such as Figure 12 As shown, the height h1 of the tray 51 of the copier / printer cabinet 50 is 154mm. Figure 3 As shown, the minimum height Hmin of the equipment maintenance device platform 12 is 140mm (the maximum height Hmax is 180mm), which meets the manufacturing and installation tolerance range of ±10mm. Meanwhile, as... Figure 12 As shown, the width B of the multifunction printer / copier 60 is 620mm, and as... Figure 2 As shown, the platform 12 of the equipment maintenance device has a width C of 620mm. Figure 12 As shown, the internal width b of the copier / printer cabinet 50 is 932mm, allowing the equipment maintenance device to enter the copier / printer cabinet 50 together with the copier / printer 60. Furthermore, there is a 312mm clearance between the copier / printer 60 and the copier / printer cabinet 50 in the width direction. Figure 13 As shown, the internal depth d of the copier and printer cabinet 50 is 966mm. Figure 3 As shown, the length D of the equipment maintenance device is 750mm, which allows the equipment maintenance device to be placed in the copier / printer cabinet 50 at the same time as the copier / printer 60 after the handrail 40 is removed, making it convenient for equipment maintenance and use.

[0064] The equipment maintenance device disclosed in this application embodiment can raise and lower the platform 12 via an adjustment mechanism 30 mounted on the chassis 11, ensuring that the platform 12 and the tray 51 inside the copier / printer cabinet 50 are aligned without any height difference, so that the copier / printer 60 can be smoothly pulled out and pushed in. Simultaneously, the moving device 20 can move the support component 10, thereby facilitating maintenance of the copier / printer 60. Furthermore, the detachable handle 40 mounted on the support component 10 allows for easy movement of the copier / printer 60, and by removing the handle 40, the equipment maintenance device can be placed together with the copier / printer 60 inside the copier / printer cabinet 50.

[0065] The equipment maintenance device disclosed in this application embodiment can raise and lower the platform 12 through the adjustment mechanism 30, which can compensate for manufacturing and installation errors of the copier and printer cabinet 50, and ensure that the platform 12 and the tray 51 inside the copier and printer cabinet 50 are connected without any height difference, thereby ensuring that the copier and printer 60 can be pulled out and pushed in smoothly, and improving the convenience of maintenance of the copier and printer 60.
