Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wallboard installation, and particularly relates to an auxiliary device and method for rail vehicle wallboard installation. BACKGROUND

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute the prior art.

[0003] In the existing rail vehicle wallboard installation process, the window lower wallboard and the window wallboard need to be directly installed at the vehicle body framework, and the operator needs to preinstall the window lower wallboard, and then two people cooperate to attach the window wallboard to the window frame based on the window lower wallboard. Because the process requires that the window wallboard and the window lower wallboard need to maintain a uniform flash joint, one more person needs to use a measuring instrument to measure the height of the window lower wallboard and the window wallboard during the installation of the window wallboard, so that the flash joint between the window lower wallboard and the window wallboard is uniform, and the height difference between the two at the joint is less than or equal to 1 mm. After adjustment, the screws are fastened in place. This process not only consumes time and effort, but also greatly increases the technical difficulty and physical consumption of construction. If the flash joint between the window lower wallboard and the window wallboard does not meet the requirements after the installation of the window wallboard is completed, the window wallboard needs to be removed and reinstalled, resulting in low efficiency of rail vehicle wallboard installation.

[0004] In addition, the window lower wallboard is installed first, and then the window wallboard is installed. During the installation of the two, drilling is required. The aluminum chips generated during the drilling operation also pose a threat to the quality and safety of the entire installation process. These small metal fragments are extremely easy to fall into the hidden space at the back of the wallboard during the drilling process. Because the location is hidden and difficult to access, it brings great inconvenience to the subsequent cleaning work. More seriously, once the aluminum chips are left near the door panel slide, they will cause irreversible scratches and wear to the accessories at the bottom of the door panel with the frequent opening and closing of the side door, thereby affecting the performance and service life of the entire vehicle. To avoid this risk, the construction personnel have to disassemble the window lower wallboard after drilling to clean it. This repeated disassembly and assembly process not only consumes time and effort, but also easily causes unnecessary bumps and damage to the wallboard and its accessories, further increasing the construction cost and risk.

[0005] Moreover, the space adjacent to the wallboard of the vehicle body column is relatively narrow. In this narrow space, the operation space of the construction personnel is extremely limited. In the prior art, the position of the window wallboard is repeatedly adjusted, and the construction personnel repeatedly operate in the narrow space, so that the safety hazards during the preinstallation of the wallboard and the adjustment of the joint between the adjacent wallboards are particularly prominent. Safety accidents such as hand squeezing and hand scratching may occur, which pose a threat to the life and health of the construction personnel.

[0006] The prior art discloses a mounting device for vehicle wall plate, mainly length adjusting device is arranged, through the length adjusting device, the force consistency of the lower wall plate and the upper wall plate can be ensured, and the positioning device of the side wall mounting seat is disclosed, but the structure of the side wall mounting seat is different from that of the wall plate, the space of the side wall mounting seat is larger, and the flash gap requirement of the window wall plate is not met, and the positioning hole of the side wall mounting seat on the side wall is mainly determined, so that the problems of low installation efficiency, safe installation of the wall plate, reduction of aluminum scraps, guarantee of the flash gap precision between the lower wall plate and the window wall plate and the like are not solved by the prior art.

[0011] The auxiliary device as described above for mounting a wall plate of a rail vehicle, in order to accurately collect the drill chips, the setting position of the drill chip collecting box corresponds to the lower wall plate mounting hole at the vehicle body frame one by one. The top of the drill cuttings collecting box is provided with an open slot, and the top of the drill cuttings collecting box is lower than the upper surface of the top support.

[0012] The height adjusting assembly is provided with a scale line, and the height of the auxiliary device is the height of the window lower wall plate plus h 闪缝 .

[0014] The support rod comprises an outer rod and an inner rod, the outer rod is hollow, the outer rod is provided with a sliding slot, the sliding slot is in communication with the inner part of the outer rod, the inner rod can freely slide in the range of the sliding slot, and the second fastener abuts against or is connected with the inner rod through the sliding slot to fasten the position of the inner rod.

[0015] The top support and the bottom support are respectively provided with folding mechanisms, the folding mechanisms of the top support and the bottom support are located in the same vertical plane, so that the auxiliary device can be folded.

[0016] The folding mechanism is a multi-folding hinge structure.

[0017] The top support and the bottom support are hollow. A tool box is fixed at the bottom support, the tool box is provided with a mounting part at the bottom, the mounting part is provided with a bayonet, and the tool box is clamped and mounted on the bottom support through the bayonet. A plurality of self-locking wheels are arranged below the bottom support.

[0018] In the second aspect, the present application further provides a rail vehicle wall plate mounting method, which adopts the auxiliary device for mounting the rail vehicle wall plate, and comprises the following contents. The auxiliary device is arranged at the mounting position of the window lower wall plate outside the vehicle body framework. The window wall plate is mounted on the upper side of the top support in the auxiliary device, and the window wall plate is attached to the upper side of the top support. The drill bit passes through the window wall plate to form a window wall plate mounting hole with the vehicle body framework, drill cuttings generated in the drilling process fall into the drill cuttings collecting box or the ground, and the fastener connects the window wall plate and the vehicle body framework. The drill bit passes through the auxiliary hole and the positioning hole to realize pre-drilling of the installation hole of the under-window wall plate at the body frame, and the drill cuttings formed during the pre-drilling process fall into the drill cutting collecting box. The auxiliary device is removed, the drill cuttings falling on the ground are disposed, and the under-window wall plate is installed below the window wall plate.

[0019] The beneficial effects of the present application are as follows: 1) The present application provides an auxiliary device to replace the under-window wall plate, and the auxiliary device is installed in place before the installation of the window wall plate. The height of the auxiliary device is higher than that of the under-window wall plate, so that the window wall plate can be directly attached to the auxiliary device during installation. This eliminates the need to repeatedly adjust the position of the window wall plate, reduces the labor required, and eliminates the need for a construction worker to measure the flash gap between the under-window wall plate and the window wall plate. The installation process is simplified by simulating the under-window wall plate, and the installation and cleaning time of each vehicle wall plate is reduced from 5 hours to 1.5 hours, significantly improving efficiency. Only two people are needed to complete the wall plate installation, saving the cost of one person, and reducing the safety hazards caused by repeated installation.

[0020] 2) In the present application, the drill cutting collecting box is provided on the side of the top bracket of the auxiliary device, and the auxiliary hole is provided in the drill cutting collecting box. The auxiliary hole is in communication with the positioning hole, and the drill bit passes through the auxiliary hole and the positioning hole to realize pre-drilling of the installation hole of the under-window wall plate at the body frame. During the pre-drilling process, the drill cuttings directly fall into the drill cutting collecting box, solving the problem of drill cuttings falling during the subsequent installation of the upper side of the under-window wall plate. The drill cuttings generated during the installation of the window wall plate fall into the drill cutting collecting box or onto the ground. With the hollow design, the problem of aluminum cuttings falling into hidden spaces is effectively solved, avoiding the problem of aluminum cuttings left behind caused by repeated disassembly of the wall plate for cleaning, ensuring construction quality, and the auxiliary device is also easy to handle drill cuttings.

[0021] 3) In the present application, the height adjusting assembly corresponds to the position of the pressing strip of the under-window wall plate, and is used to position the installation of the auxiliary device to ensure accurate installation of the auxiliary device.

The scale line ensures uniform flash gap of the wall plate, reduces the time for manual measurement and marking, and reduces the construction technical difficulty. The height of the auxiliary device is the height of the under-window wall plate + h 闪缝 , which can quickly ensure the flash gap between the window wall plate and the under-window wall plate.

[0022] 4) In this invention, the top support and the bottom support are respectively equipped with folding mechanisms. The folding mechanism allows the auxiliary device to be folded, which is convenient for storing the auxiliary device. It can be opened when needed. The self-locking wheel also facilitates the movement of the entire auxiliary device, and helps to ensure the stability of the auxiliary device after movement.

[0023] 5) This invention provides a wall panel installation method. First, an auxiliary device is installed, and then the window wall panel is set. The window wall panel fits snugly against the upper side of the top bracket. The gap between the window wall panel and the lower wall panel can be ensured without repeatedly adjusting the position of the window wall panel. This is conducive to the rapid installation of segmented wall panels. Moreover, the drill cuttings can be collected by setting up a drill cuttings collection box. Due to the change in the overall process, the auxiliary device can be removed after the window wall panel is installed. Even if drill cuttings are generated during the installation process, they are easy to remove, reducing problems such as bumps and knocks caused by drill cuttings. Attached Figure Description

[0029] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. As described in the background section, existing rail vehicle wall panels suffer from problems such as low efficiency, high construction difficulty, and safety hazards during installation. In order to solve the above-mentioned technical problems, this invention proposes an auxiliary device for installing rail vehicle wall panels.

[0031] Example 1 In a typical embodiment of the present invention, reference is made to Figure 1 As shown, an auxiliary device for installing a wall panel on a rail vehicle includes an auxiliary device for replacing a window lower wall panel. The auxiliary device is hollowed out, and its height is greater than the height of the window lower wall panel to be installed. The length of the auxiliary device is less than or equal to the length of the window lower wall panel. The auxiliary device includes a top bracket 1 and a bottom bracket 10, which are connected by a height adjustment component. The height of the height adjustment component is adjustable. The top bracket 1 has multiple positioning holes. A drill cuttings collection box 4 is open and placed on the outside of the top bracket 1. The drill cuttings collection box 4 has an auxiliary hole 12, which is connected to and coaxial with the positioning holes. A drill bit passes through the auxiliary hole 12 and the positioning holes to pre-drill holes for the window lower wall panel installation holes at the vehicle frame. The hollowed-out design of the auxiliary device facilitates the observation of drill cuttings falling during the installation of the window wall panel 13.

[0032] The top support 1 is located on the top of the auxiliary device. The top support 1 is used to fix and support other components. The positioning hole is set along the thickness direction of the top support. Multiple drill cuttings collection boxes 4 are provided along the length direction of the top support 1. One side of the drill cuttings collection box 4 is fixed to the top support 1 by a first fastener such as a screw. The drill cuttings collection box 4 is provided with an auxiliary hole 12 coaxial with the positioning hole. The auxiliary hole 12 passes through the two side walls of the drill cuttings collection box 4. To ensure accurate collection of drill cuttings, the drill cuttings collection box 4 is positioned so that it corresponds one-to-one with the mounting holes of the window wall panel on the vehicle frame. The top of the drill cuttings collection box 4 is provided with an open slot, and the top of the drill cuttings collection box 4 is lower than the upper surface of the top bracket 1 to avoid interference between the drill cuttings collection box 4 and the window wall panel 13.

[0033] When pre-drilling holes in the vehicle frame (including the corresponding positions of the vehicle frame in the window wall panel and the lower window wall panel), the falling drill shavings, such as aluminum shavings, are in the visible interface and are partially collected in the drill shavings collection box. This solves the problem of difficult cleaning of aluminum shavings in the hidden space behind the vehicle, reduces cleaning time, and avoids quality problems such as damage to parts and aluminum shavings left behind caused by repeatedly disassembling the lower window wall panel to clean aluminum shavings.

[0034] In this embodiment, the height of the auxiliary device is the height of the wall panel below the window + h. 闪缝 This can quickly ensure the gap between the window wall panel 13 and the lower window wall panel, eliminating the need for repeated adjustments to the installation of the window wall panel 13 to ensure this gap 14, as required by existing technologies. During operation, the height of the auxiliary device is adjusted to the height of the lower window wall panel of the corresponding vehicle model + 0.5cm, which serves as the standard for the gap between the wall panels.

[0035] Specifically, the height adjustment component includes multiple support rods 2, including side support rods and a central support rod. The side support rods and the central support rod are used to position the trim strip of the lower wall panel. The side support rods connect the sides of the top bracket 1 and the bottom bracket 10, and the central support rod connects the middle of the top bracket 1 and the bottom bracket 10. Each support rod 2 is height-adjustable. There are three support rods 2: a left side support rod, a central support rod, and a right side support rod. The height of the support rods 2 is adjustable to adapt to the needs of different vehicle models.

[0036] In this embodiment, to achieve height adjustment of the support rod 2, the support rod 2 includes an inner rod 7 and an outer rod 8. The outer rod 8 is hollow, and the inner rod 7 is nested inside the outer rod 8, forming a telescopic structure. A vertical sliding groove is formed on the outer rod 8, communicating with the interior of the outer rod 8. A bolt 9 passes through the sliding groove and abuts or connects with the inner rod 7. In some examples, the surface of the inner rod 7 has protective textures to facilitate the abutment of the bolt 9 with the inner rod 7; or, in some examples, the inner rod 7 has multiple threaded holes to facilitate the installation of the bolt 9. When height adjustment is required, the bolt is loosened, and the inner rod 7 can slide freely within the sliding groove range, achieving stepless adjustment. After adjusting to the desired height, the bolt 9 is tightened, fixing the inner rod 7 and the outer rod 8 together and locking the height. Both the outer rod 8 and the inner rod 7 of the support rod 2 have scale markings. The height of the outer rod 8 includes the height of the self-locking wheel and the bottom support 10, and the height of the inner rod 7 includes the height of the top support 1, allowing operators to quickly adjust the height of the support rod according to the scale markings.

[0037] In this embodiment, both the top support 1 and the bottom support 10 are frame-shaped structural components, and both are hollow to reduce the overall weight. The support rod is placed in the hollow part of the top support 1 and the bottom support 10 and welded together.

[0038] It is easy to understand that both the top bracket 1 and the bottom bracket 10 are wrapped with rubber protective layers. The rubber protective layers can not only effectively isolate the direct contact between the device and the vehicle body frame, wall panels and floor cloth, prevent scratching or damage, but also provide additional buffering to ensure the stability during the installation process.

[0039] It should be noted that the folding mechanism 3 is arranged in the middle of the top bracket 1 and the bottom bracket 10. That is, the top bracket 1 includes two sections, and the bottom bracket 10 also includes two sections, making the auxiliary device form a symmetric structure. The folding function of the auxiliary device is realized through the folding mechanism 3, which is convenient for storage and transportation. Specifically, the folding mechanism 3 is a multi-fold hinge structure. Among them, the middle support rod is arranged close to the folding mechanism 3.

[0040] To facilitate the quick installation of the window wall panel 13 on site, the toolbox 5 is installed on the upper side of the bottom bracket 10. The toolbox 5 is used to store tools. The toolbox 5 contains tools such as an electric screwdriver and a glue gun, which reduces the time for construction workers to fetch tools back and forth and improves the construction efficiency.

[0041] Specifically, the longitudinal section of the toolbox 5 is an inverted trapezoid. The toolbox 5 is open at the top. An installation part 11 is arranged at the bottom of the toolbox 5. The installation part 11 is arranged along the width direction of the toolbox. The installation part 11 is an installation block. The installation part 11 is provided with a bayonet. The width of the bayonet is adapted to the width of the bottom bracket 10. The toolbox 5 is installed on the bottom bracket 10 by being clamped by the bayonet. The installation method of the toolbox 5 can also be quickly removed, which is beneficial to changing the position of the toolbox 5.

[0042] It needs to be explained that the self-locking wheels 6 are installed on the bottom bracket 10. Multiple self-locking wheels 6 are arranged on the lower surface of the bottom bracket 10 at an interval. The self-locking wheels 6 refer to the existing wheels with self-locking functions, which are convenient for moving and fixing the position of the device.

[0043] The auxiliary device is used to simulate the window lower wall panel. During use, the auxiliary device is closely attached to the position of the vehicle body frame. The top bracket 1 and three support rods with adjustable heights are combined into a "day" - shaped structure. When reading the height of the support rod 2, when the inner rod 7 extends out, the height reading position is the lowest end of the inner rod. When setting the height of the auxiliary device, the height of the auxiliary device is adjusted to the height of the window lower wall panel of the corresponding vehicle model + 0.5 cm, which is used as the standard for the wall panel flashing gap 14, effectively solving the problem of uneven wall panel flashing gap. After using the device, only two people are needed to hang the window wall panel 13 based on the auxiliary device. At the same time, the auxiliary device cooperates with the vehicle body frame, and the three support rods 2 can locate the position of the window lower wall panel pressing strip, reducing the measurement and marking time of construction workers, improving the wall panel construction efficiency, and saving one person in labor; after the device is in place, the self-locking wheels can be locked to prevent the device from moving randomly.

[0044] After use, the auxiliary device can be folded. When folded, the left side support rod and the right side support rod overlap and align. The overall structure is compact and easy to transport and store.

[0045] In summary, this auxiliary device not only possesses lightweight and flexible characteristics, but also incorporates features such as height adjustment and a multi-functional toolbox, significantly improving construction efficiency and quality while reducing labor costs and rework rates. It minimizes the probability of workers being trapped by repeated rework, enhancing work safety. It is suitable for installing window wall panels 13 on various vehicle models. The device features a folding function, making it compact after folding, facilitating transportation and storage.

[0046] Example 2 This embodiment provides a method for installing rail vehicle wall panels, using an auxiliary device for installing rail vehicle wall panels as described in Embodiment 1, including the following: An auxiliary device is installed at the installation position of the lower wall panel of the outer side window of the vehicle body frame; In the auxiliary device, a window wall panel 13 is installed on the upper side of the top bracket 1. The window wall panel 13 is placed on the upper side of the top bracket 1 and is attached to the upper side of the top bracket 1. The drill bit passes through the window wall panel 13 and forms a window wall panel mounting hole with the vehicle frame. The drill cuttings generated during the drilling process fall into the drill cuttings collection box or fall to the ground. Fasteners connect the window wall panel 13 with the vehicle frame. The drill bit passes through the auxiliary hole 12 and the positioning hole to pre-drill the mounting hole of the window wall panel at the vehicle frame. The drill cuttings formed during the pre-drilling process fall into the drill cuttings collection box 4. Remove the auxiliary device, clean up the drill bits that have fallen to the ground, and install the window lower wall panel below the window wall panel 13.

[0047] The wall panel installation method provided in this embodiment involves first installing the auxiliary device, and then setting the window wall panel. The window wall panel fits snugly against the upper side of the top bracket, ensuring a gap between the window wall panel and the lower wall panel without repeatedly adjusting the position of the window wall panel. This facilitates the rapid installation of segmented wall panels. Furthermore, the drill cuttings collection box allows for the collection of drill cuttings. Due to the change in the overall process, the auxiliary device can be removed after the window wall panel is installed. Even if drill cuttings are generated during installation, they are easy to remove, reducing problems such as bumps and knocks caused by drill cuttings.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
