An all-directional maintainable equipment integrated installation structure

Abstract

When the equipment is installed on the wall outside the cabin, maintenance can only be carried out after the obstructions are removed outside the cabin when the equipment is replaced as a whole or the forward module of the equipment is maintained. This type of equipment maintenance often requires large tooling such as cranes, slings, and obstruction disassembly and assembly tools. It is also subject to the influence of weather conditions, is time-consuming, labor-intensive, and full of uncertainty. In order to overcome the deficiencies in the prior art, the present invention proposes an omnidirectional maintainable equipment integrated installation structure. Under the premise of meeting the requirements of wall-mounted installation outside the cabin, through the innovative design of a rotating transition strip, the overall replacement of the equipment and maintenance of all modules can be achieved in the cabin without removing the obstructions on the outside of the equipment or entering the shelter outside the cabin, which greatly improves the maintainability of the wall-mounted detection equipment.

Description

Technical Field

[0001] The invention belongs to the field of mechanical structures, and in particular relates to an omnidirectional maintainable equipment integrated installation structure. Background Art

[0002] With the improvement of various detection technologies, the structure of detection equipment is becoming more and more complicated, and a single device often has multiple internal modules that need to be maintained. Among them, a type of external detection equipment represented by photoelectric detection equipment, thermal imaging instruments, radars, etc. requires that the detection surface must face the outside of the cabin, so most of them are installed by hanging on the side holes of the cabin wall, with the detection surface facing outward, and installing a shield or shelter that does not affect the detection performance on the outermost layer.

[0003] The wall-mounted installation methods of this type of detection equipment can be divided into two types: inside the cabin and outside the cabin. In some scenarios, only the wall-mounted installation outside the cabin can be considered. When the entire equipment is replaced or the forward module of the equipment is maintained, it is necessary to remove the shielding outside the cabin before maintenance can be carried out. This type of equipment maintenance often requires large tooling such as cranes, hoists, and shielding disassembly and assembly tools. It is also affected by weather conditions, which is time-consuming, labor-intensive and full of uncertainty. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention proposes an omnidirectional maintainable equipment integrated installation structure. Under the premise of meeting the requirements of wall-mounted installation outside the cabin, through the innovative design of rotating transition strips, there is no need to remove the obstructions on the outside of the equipment or enter the shelter outside the cabin. The overall replacement of the equipment and maintenance of all modules can be achieved in the cabin, which greatly improves the maintainability of the wall-mounted detection equipment.

[0005] The present invention discloses an omnidirectional maintainable equipment integrated installation structure, the scheme architecture and structural composition of which are shown in FIG1 , and is composed of a cabin wall (1), equipment (2) and a shielding object (3); wherein the equipment (2) comprises an equipment frame (2-1), a front-end module (2-2), a rear-end module (2-3), an upper transition strip (2-4), a limit block (2-5), an upper pin shaft (2-6), a screw (2-7), a lower transition strip (2-8), an anti-wear sheet (2-9) and a lower pin shaft (2-10).

[0006] During integrated installation, the device (2) is first mounted on the cabin wall (1) outside the cabin, and then the shielding object (3) is installed on the cabin wall (1) from outside the cabin; a maintenance hole is opened in the cabin wall (1) at a corresponding position of the device (2), and maintenance of the rear-end functional module of the device (2) is completed inside the cabin; the front-end module (2-2) and the rear-end module (2-3) are installed on the device frame (2-1), and the disassembly and assembly operation of the front-end module (2-2) is completed at the front end of the device frame (2-1), and the disassembly and assembly operation of the rear-end module is completed at the rear end of the device frame (2-1).

[0007] The equipment (2) is interconnected with the upper and lower sides of the cabin wall (1) through the transition of the upper transition bar (2-4) and the lower transition bar (2-8), and the upper transition bar (2-4) is fixedly connected to the cabin wall (1) through four through holes thereon; after the upper pin shaft (2-6) passes through the central circular hole of the upper transition bar (2-4) and the central circular hole of the upper part of the equipment frame (2-1), the four support ears of the upper transition bar (2-4) are fixedly connected to the four support ears of the upper part of the equipment frame (2-1) by screws (2-7); the lower pin shaft (2-10) and the anti-wear plate (2-9) are sequentially installed into the central circular hole of the lower part of the equipment frame (2-1) by screws (2-7), the shaft head of the lower part of the lower pin shaft (2-10) is inserted into the central circular hole of the lower transition bar (2-8), and then the four support ears of the lower transition bar (2-8) are fixedly connected to the four support ears of the lower part of the equipment frame (2-1) by screw fasteners, thereby completing the integrated installation.

[0008] Furthermore, the shielding object (3) is a protective cover, a shelter or a wall that people cannot directly enter.

[0009] Furthermore, after removing the screws between the equipment frame (2-1) and the upper and lower transition bars (2-4, 2-8), the equipment (2) can be rotated around the vertical axis formed by the upper and lower pin shafts (2-6, 2-10). When the equipment body is rotated 180°, the front-end module (2-2) is turned to the inside of the cabin, and the module maintenance and replacement operations can be carried out in the cabin.

[0010] Furthermore, the upper and lower pin shafts (2-6, 2-10) between the equipment frame (2-1) and the upper and lower transition bars (2-4, 2-8) are separable, and the equipment frame (2-1) and the upper and lower transition bars (2-4, 2-8) can be separated in the cabin by rotating 90 degrees, thereby achieving the purpose of replacing the equipment as a whole in the cabin without removing the shielding outside the cabin.

[0011] Furthermore, after the equipment frame (2-1) rotates 180°, the equipment is restricted from further rotation by the limit ears extending from the upper and lower transition bars (2-4, 2-8), and the limit ears and the equipment ears are fixed inside the cabin by screws.

[0012] Furthermore, the lower pin shaft (2-10) is fixedly connected to the equipment, and after being padded with the anti-wear sheet (2-9), it is inserted into the circular hole of the lower transition bar (2-8); the upper pin shaft (2-6) is an independent detachable structure, and is passed through the circular hole of the transition bar (2-4), the limit block (2-5) and the circular hole on the top of the equipment frame (2-1) from top to bottom, and is fastened with the limit block (2-5); when the equipment rotates, the limit block ensures that the height of the equipment body moving upward is less than the depth of the lower pin shaft (2-10) inserted into the circular hole of the lower transition bar (2-8), thereby achieving safe limit and eliminating the risk of equipment slipping; when the entire device needs to be removed, the limit block (2-5) is removed together with the upper pin shaft (2-6), leaving enough top space to ensure that the lower pin shaft (2-10) can escape from the circular hole of the lower transition bar (2-8).

[0013] The beneficial effects of the present invention are

[0014] 1) Increased convenience of equipment maintenance: All maintenance work on modules and units can be carried out inside the cabin, without the need to operate outside the cabin or remove shielding objects. As a result, a series of tools such as aerial lifts, cranes, hoists, and shielding removal tools can be omitted.

[0015] 2) Equipment maintenance is not affected by environmental factors: All operations are performed inside the cabin. Compared with traditional maintenance outside the cabin, it is not affected by external environmental factors, and the operating environment and safety conditions are good.

[0016] 3) Relaxation of the constraints on the reliability and layout of the internal components of the equipment: In traditional outdoor maintenance, in order to reduce the frequency of outdoor maintenance, the components outside the equipment cabin are often required to have high reliability, so as to achieve the purpose of maintenance-free, which is bound to cause design redundancy. Or all modules are plugged in and out from the back to avoid the need for front maintenance, but the layout constraints caused by this may cause the system to compromise on certain functional performance.

[0017] 4) Applicable to all detection equipment installed on the cabin wall, and also applicable to other functional equipment installed in other platforms with similar maintenance requirements. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] (1) Conventional connection status

[0026] In normal operation, as mentioned above, the equipment frame 2-1 is fixedly connected to the upper and lower transition bars 2-4 and 2-8 through two upper and lower pins and a total of 8 upper and lower lug holes. The upper and lower transition bars 2-4 and 2-8 are respectively fixedly connected to the cabin wall 1 through four installation through holes. All components together form a stable rigid structure to ensure the normal operation of the equipment. The installation state of the conventional fixed connection state is as follows Figure 3 and Figure 4 The posture is shown in I.

[0027] (2) Back-end equipment maintenance

[0028] A maintenance hole is opened in the cabin wall 1 at the position corresponding to the equipment 2, and the maintenance personnel can disassemble and maintain the back-end equipment 2-3 in the cabin through the maintenance hole.

[0029] (3) Front-end equipment maintenance

[0030] like Figure 3 and 4 As shown, without removing the shield 3, maintenance personnel can perform maintenance on the front-end device 2-2 in the cabin. After removing the 8 screws between the equipment frame 2-1 and the upper and lower transition bars (2-4, 2-8), the equipment body can rotate around the vertical axis formed by the upper and lower pins (2-6, 2-10). After the equipment body rotates 180° (posture I→II→III→IV), the front-end device 2-2 moves to the inside of the cabin, and maintenance and replacement operations can be performed in the cabin. The specific implementation plan is as follows:

[0031] 1) In order to avoid the obstruction of the rotation by the mounting ears, the mounting ears between the transition bar and the equipment frame need to be arranged in a staggered manner. Taking the above transition bar 2-4 as an example, in the top view, the array mounting ears 2-1a / b located on the left side of the rotation axis in the conventional fixed state (posture I) are arranged on the inside of the cabin, and the upper transition bar mounting ears 2-4a / b are arranged on the outside of the cabin; the layout of the ears on the right side of the rotation axis is opposite to that on the left side. The same is true for the lower transition bar.

[0032] 2) In order to avoid interference between the two side ears after rotation, the left and right ears need to be arranged asymmetrically. Take the transition strip 2-4 above as an example. Figure 4 In posture I, the distances from the four lugs 2-4a / b / c / d to the central axis (i.e. La / Lb / Lc / Ld in the figure) should be different from each other, and the spacing between them should take into account the thickness of the lugs. Otherwise, the device body will not be able to rotate to posture IV, that is, the rotation angle cannot reach 180°. The same situation applies to the lower transition bar.

[0033] 3) In order to ensure that there is no risk of the equipment falling during rotation, a safety limit design is required. During rotation, the equipment body is only interconnected with the upper and lower transition bars 2-4 / 2-8 through the upper and lower pins 2-6 / 2-10. There is a risk that the pin will slip out of the equipment or the center hole of the transition bar, causing the equipment to fall. When designing the upper and lower pins, it should be ensured that after the pins are installed, the height that the equipment can move up and down is less than the depth of the lower pin 2-10 inserted into the center hole of the lower transition bar 2-8, and a safety margin should be left, that is, Figure 2 In the equation, h2

[0034] 4) In order to ensure that the array can be fixed after the equipment is rotated 180°, it is convenient to operate, and a fixed design is required. A fixed limit lug 2-4e is reserved on the upper transition bar 2-4, and its distance from the central axis should be the same as 2-1a, that is, Le = La. In this way, after the equipment is rotated 180°, the lug 2-4e can be in the continuous state of the equipment, and the array can be fastened in the cabin with screws. The same is true for the lower transition bar.

[0035] 5) In order to ensure that all operations are carried out in the cabin, it is necessary to ensure that the mounting screws between the equipment frame 2-1 and the upper and lower transition strips 2-4 and 2-8 must be installed from the cabin, that is, the screws must be designed to be installed internally. Under the premise of the staggered layout of the lugs mentioned above, the lugs 2-1a, 2-1b, 2-4c and 2-4d on the inner side of the cabin in the normal fixed state (posture I) should have through holes, and the lugs 2-4a, 2-4b, 2-1c and 2-1d on the outer side of the cabin should have threaded holes. Similarly, in order to ensure that the fixation is also carried out in the cabin when rotating 180°, 2-4e should have a threaded hole, and the same is true for the lower transition strip.

[0036] ​6) In order to ensure smooth rotation of the equipment, anti-wear design is required. When the equipment rotates, the weight of the entire equipment is transferred to the lower transition bar 2-8 through the lower pin 2-10, and the two rotate relative to each other, so an anti-wear sheet 2-9 needs to be set between 2-10 and 2-8.

[0037] 7) The restoration and installation of the front-end module 2-2 is the reverse process of the removal.

[0038] (4) Overall equipment replacement

[0039] Without removing the shield 3, maintenance personnel can replace the entire device body (including the device frame 2-1, the front-end module 2-2 and the rear-end module 2-3) in the cabin. After removing the 8 screws between the device frame 2-1 and the upper and lower transition bars (2-4, 2-8), the device body can rotate around the vertical axis formed by the upper and lower pins (2-6, 2-10). When the device body rotates to about 90°, the pin is detached, and the device body can be removed as a whole from the inside of the cabin. The posture change path is posture I→V→VI", as shown in FIG. Figure 5 The specific implementation scheme is as follows:

[0040] 1) In order to ensure that the equipment can be dismantled as a whole, the pin shaft should be designed to be detachable. Figure 2 Schematic diagram. The lower pin 2-10 and the anti-wear block 2-9 are fixedly connected to the central circular hole at the lower end of the equipment frame 2-1 and move with the equipment frame; the upper pin 2-6 is designed to be removable. During installation, the upper pin 2-6 passes through the upper transition bar 2-4 and the circular holes on the upper part of the equipment frame 2-1 from top to bottom, and is fixedly connected to the limit block 2-5 at the lower part of the upper transition bar 2-4 by screws. When it is not necessary to dismantle (posture I, posture V), the height h2 that the equipment frame can move upward is less than the depth h1 of the lower pin 2-10 inserted into the center hole of the lower transition block 2-8, and the equipment cannot fall out, ensuring safety. When it is necessary to dismantle (posture VI), after removing the limit block 2-5 and the upper pin 2-6, the height h3 that the equipment frame can move upward is greater than the depth h1 of the lower pin 2-10 inserted into the center hole of the lower transition block 2-8, that is, Figure 2 In the equation, h3>h1+Δh, (Δh refers to the safety margin).

[0041] During the specific operation, when the equipment body is in a 90° posture (posture V), after removing the limit block 2-5 and the upper pin shaft 2-6, lift it upward to separate the equipment body from the upper and lower transition bars, and then move the equipment out from the inside of the cabin. All operations are performed in the cabin. Although the limit block 2-5 and the upper pin shaft 2-6 are located outside the cabin, in posture V, the equipment is in a 90° posture, and there are enough holes around it to ensure that personnel can reach out and complete the disassembly and assembly of the two parts in the cabin.

[0042] The restoration and installation of the equipment is the reverse process of dismantling.

[0043] (5) Workshop assembly plan

[0044] During workshop assembly, this solution supports two assembly schemes: installation inside the cabin and installation outside the cabin.

[0045] 1) Installation outside the cabin: After the equipment 2 is assembled as a whole, it is installed as a whole on the cabin wall 1 from the outside of the cabin, and then the shielding object 3 is assembled.

[0046] 2) Cabin installation solution: In the case where the shield 3 has been installed, the equipment needs to be integrated and assembled inside the cabin. First, the upper and lower transition strips (2-4, 2-8) are installed on the cabin wall 1 through the holes in the cabin wall 1, and then the equipment body is installed on the transition strips.

[0047] Furthermore, the above description only takes the maintenance of the front and rear modules installed on the front and rear surfaces of the equipment as an example, but this solution is also applicable to the maintenance of side-mounted and top-mounted modules, and essentially has comprehensive maintainability capabilities.

[0048] Example

[0049] This technical solution has been applied to a certain device. In the embodiment, the width of the device body is 600mm and the height is 350mm. The width of the hole at the corresponding position of the cabin wall is 780mm and the height is 400mm. Figure 4 As shown, La=Le=240mm, Lb=200mm, Lc=160mm, Ld=280mm; in the direction of pin arrangement, the diameters of the upper and lower pins are designed to be 15mm, h1=10mm, h2=5mm, h3=15mm. In terms of component material selection, the equipment frame and upper and lower transition bars 2-4 / 2-8 are made of high-strength aluminum alloy, the upper and lower pins 2-6 / 2-10 are made of titanium alloy, and the anti-wear sheet 2-9 is made of polytetrafluoroethylene.

[0050] The electrical interconnection between the front-end module 2-2, the back-end module 2-3 and the equipment frame 2-1 adopts a blind plug design, which further improves the convenience of equipment maintenance.

[0051] Handles are designed and installed on both sides of the equipment frame 2-1, which further improves the operability of the overall dismantling of the equipment.

[0052] The screw fastener 2-7 and the upper pin shaft 2-6 are designed to be a non-loose screw structure, which avoids the risk of the screw slipping when removing the upper pin shaft from the inside of the cabin.

[0053] Other small detection equipment can be installed in the empty space inside the shield 3 and outside the cabin wall 1. Since the equipment body of this case can be rotated 90 degrees or completely removed to make way for maintenance holes, maintenance of other small detection equipment is achieved, further improving the maintainability of the entire machine.

[0054] The present invention is not limited to the above specific implementations, and the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made to the above implementations based on the technical essence of the present invention shall be included in the protection scope of the present invention.
