Description

Technical Field

[0001] This utility model relates to the field of rail vehicle manufacturing technology, and in particular to a rail vehicle glass mounting device. Background Technology

[0002] Rail vehicle manufacturing refers to the process of producing vehicles for use on railway lines, urban rail transit, and other similar lines. It encompasses everything from design and planning to component manufacturing, assembly, and testing, producing vehicles such as subways, high-speed trains, and light rails, ensuring their performance, safety, and quality meet standards before they are put into operation.

[0003] The installation of subway car glass typically involves the following steps: placing the glass flat on the platform with the surface to be installed facing up; performing a series of surface treatments on the edges of the glass surface to be installed and the surface of the car body window frame to be installed; applying adhesive to the surface to be installed on the car body, while placing rubber pads under the window frame for height adjustment; finally, using a vacuum suction cup to lift the glass and install it onto the car body, and adjusting the gaps and flatness around the glass.

[0004] Currently, there are two main installation methods: workers use handheld double-claw suction cups to lift the glass to the installation surface, then manually flip the glass over and adjust the gap between the glass and the vehicle body after bonding; or a robotic arm is used with a suction cup device to adsorb the glass, but this method still requires manual flipping of the glass.

[0005] The shortcomings of the existing technical solutions are as follows: In the surface treatment stage of subway car glass installation, the glass to be installed must be placed face up to allow for surface treatment around its edges. However, before subsequent glass installation, the glass must be manually rotated 180°. During this operation, hands are highly likely to touch the already treated surface around the glass, increasing the risk of contaminating the glass bonding surface. Furthermore, the installation surface of the car window frame is not flat but rather inclined. Ordinary suction cup hangers lack the function of adjusting the glass installation angle, making it difficult to accurately position the glass on the window frame in one go, requiring significant time for repeated adjustments to the installation effect. Utility Model Content

[0006] This invention provides a glass installation device for rail vehicles, which can solve the problem that the glass is easily contaminated around its edges when manually flipping it in the prior art.

[0007] A glass installation device for rail vehicles includes a mobile lifting device. The lower end of the mobile lifting device is provided with a hinge joint. Connecting rods are movably hinged to both sides of the hinge joint. Each set of connecting rods is movably hinged to the other end of a support member. The support member is provided with a fixing component for fixing the glass. The lifting device is provided with a drive mechanism for rotating the connecting rods.

[0008] As a further embodiment of this utility model: each set of fixing components includes multiple sets of suction cups fixedly disposed at the bottom of the support.

[0009] As a further embodiment of this utility model: each set of support members is fixed with multiple sets of negative pressure tubes for changing the negative pressure state inside the suction cup, and the other end of the negative pressure tube is connected to an electric vacuum pump.

[0010] As a further embodiment of this utility model: the driving mechanism includes an automatic telescopic assembly symmetrically rotatably disposed on both sides of the mobile lifting device, and a connecting block is fixedly disposed on each set of connecting rods, and the telescopic end of the automatic telescopic assembly is movably connected to the connecting block.

[0011] As a further embodiment of this utility model: the automatic telescopic component is a hydraulic telescopic rod, which is configured between the mobile lifting device and the connecting block.

[0012] As a further embodiment of this utility model: the support member is fixedly provided with an adjustment handle that facilitates the worker to adjust the orientation of the suction cup on the support member.

[0013] As a further embodiment of this utility model: each set of support members is provided with four sets of suction cups, which are distributed in a matrix at the bottom of the support members.

[0014] As a further embodiment of this utility model: each set of support members is a rectangular plate, and the four sets of suction cups are respectively distributed at the corner positions of the support members.

[0015] As a further embodiment of this utility model: grooves for limiting the connecting rod are provided on both sides of the hinge joint.

[0016] As a further embodiment of this utility model, the negative pressure tube is a flexible rubber tube.

[0017] The beneficial effects of this utility model are:

[0018] 1. In use, the fixing components on the two sets of support members can alternately adsorb the glass. During the glass handling stage, one set of fixing components adheres to the glass surface to be installed, ensuring the stability of the glass during handling; while during glass installation, the other set of fixing components adheres to the other side of the glass, thereby releasing the adsorption of the surface to be installed. This design eliminates the need for manual flipping of the glass surface during installation, effectively avoiding human contact with the already treated surface of the glass, fundamentally eliminating the risk of contamination of the glass bonding surface, and ensuring the quality of glass installation and the reliability of subsequent use.

[0019] 2. In use, considering the inclined surface of the vehicle window frame, this utility model incorporates a drive mechanism to adjust the deflection angle of the connecting rod. Operators can easily adjust the angle of the support and its suction cups by operating the adjustment handle on the support, ensuring the glass fits snugly against the vehicle window frame mounting surface at a suitable angle. This feature allows the glass to be precisely positioned on the window frame in one go, eliminating the need for repeated adjustments as in traditional methods, thus improving installation efficiency.

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0027] like Figures 1 to 4As shown in the figure, this utility model provides a rail vehicle glass installation device, including a mobile lifting device 1. The mobile lifting device 1 serves as the support and moving body of the entire device, and can move flexibly within the working area to facilitate the transport of glass to the designated installation position. A hinge joint 2 is provided at the lower end of the mobile lifting device 1. Connecting rods 3 are movably hinged to both sides of the hinge joint 2. A support member 4 is movably hinged to the other end of each set of connecting rods 3. Fixing components for fixing the glass are provided on the support member 4. This hinge structure allows the support member 4 and its fixing components to have a certain range of motion to better adapt to the glass installation requirements. The two sets of fixing components on the two sets of support members 4 can alternately adsorb the glass. Specifically, during glass transport, one set of fixing components is responsible for adsorbing the surface of the glass to be installed, ensuring the stability of the glass during transport; while during glass installation, the other set of fixing components cooperates with the aforementioned fixing components to adsorb the other side of the glass, thereby releasing the adsorption on the surface to be installed. In this way, when installing the glass, the surface to be installed can be directly facing the vehicle window frame, avoiding the step of manually flipping the glass and greatly reducing the risk of contamination of the surrounding surface of the glass.

[0028] In order to adjust the installation angle of the glass, the hanger is equipped with a drive mechanism 5 that drives the connecting rod 3 to rotate. The main function of the drive mechanism 5 is to adjust the deflection state of the connecting rod 3 to facilitate the fixing of the glass and to enable the glass to be installed on the vehicle window frame at a suitable angle.

[0029] In one specific embodiment, each fixing assembly includes multiple sets of suction cups 401 fixedly disposed at the bottom of the support member 4. The suction cups 401 adsorb the glass by generating negative pressure and are key components for fixing the glass. Each support member 4 is fixed with multiple sets of negative pressure tubes 403 for changing the internal negative pressure state of the suction cups 401. The negative pressure tubes 403 are preferably flexible rubber tubes. Flexible rubber tubes have good flexibility and sealing properties, and can adapt to the working requirements of the suction cups 401 at different angles. The other end of the negative pressure tube 403 is connected to an electric vacuum pump. The electric vacuum pump continuously maintains the adsorption effect of the suction cups 401 through the negative pressure tube 403, thereby ensuring the stability of the glass during handling and preventing the glass from slipping or shaking during transport.

[0030] In another specific embodiment, the drive mechanism 5 includes an automatic telescopic assembly 501 symmetrically rotatably disposed on both sides of the movable lifting device 1. The automatic telescopic assembly 501 is preferably a hydraulic telescopic rod. Hydraulic telescopic rods have advantages such as simple structure and high load-bearing capacity, and can stably drive the connecting rod 3 to rotate. Of course, the automatic telescopic assembly 501 can also be other components that can drive the connecting rod 3 to rotate along one side of the hinge joint 2. Each set of connecting rods 3 is fixedly provided with a connecting block 502, and the telescopic end of the automatic telescopic assembly 501 is movably connected to the connecting block 502. When the automatic telescopic assembly 501 performs telescopic movement, by adjusting the distance between the connecting block 502 and the movable lifting device 1, one end of the connecting rod 3 is hinged and rotated with the hinge joint 2, thereby adjusting the tilt angle of the connecting rod 3. Furthermore, to ensure the stability of the connecting rod 3 during movement, grooves for limiting the movement of the connecting rod 3 are provided on both sides of the hinge joint 2. The grooves can limit the range of motion of the connecting rod 3, preventing the connecting rod 3 from shifting or swaying during rotation.

[0031] Because the mounting surface of the vehicle window frame is angled, the installation angle of the glass needs to be adjusted during installation so that workers can accurately install the glass onto the mounting surface of the vehicle window frame, ensuring a proper fit between the glass and the vehicle body after bonding. To meet this requirement, an adjustment handle 402 is fixedly installed on the support member 4 to facilitate workers in adjusting the orientation of the suction cup 401 on the support member 4. Workers can easily adjust the angle of the support member 4 and its suction cup 401 by operating the adjustment handle 402, thereby allowing the glass to fit against the vehicle window frame at a suitable angle.

[0032] To facilitate a better understanding of the structure and working principle of this device by those skilled in the art, such as Figure 2 As shown, in this embodiment, each support member 4 is equipped with four sets of suction cups 401, and these four sets of suction cups 401 are distributed in a matrix at the bottom of the support member 4. Each support member 4 is a rectangular plate, and the four sets of suction cups 401 are respectively distributed at the four corners of the support member 4. This distribution method allows the suction cups 401 to be evenly distributed on the glass surface, thereby generating a more stable and reliable adsorption force, making it easier for workers to push the support member 4 to adhere to the glass, thus achieving the fixation and handling of the glass.

[0033] Working Principle: In use, the movable lifting device 1 is moved to a suitable position above the glass to be installed. The electric vacuum pump is started, and negative pressure is formed inside the suction cup 401 at the bottom of the support member 4 through the negative pressure pipe 403, thereby firmly adsorbing the glass surface to be installed. The movable lifting device 1 moves the glass up to a certain height. Then, another set of suction cups 401 approach. The automatic telescopic component 501 in the drive mechanism 5 starts to work, and its telescopic end drives the connecting block 502 to move, thereby causing the connecting rod 3 to rotate around the hinge joint 2. As the connecting rod 3 rotates, the other set of support members 4 and the suction cups 401 on it gradually approach the other side of the glass. Since the hinge joint 2 has grooves on both sides to limit the connection rod 3, the stability of the connection rod 3 during rotation is ensured, allowing the suction cups 401 to accurately approach the glass.

[0034] Once the other set of suction cups 401 approaches the other side of the glass and reaches a suitable position, the suction surface switching operation is performed. The electric vacuum pump adjusts the negative pressure state within the negative pressure tube 403 (multiple electric vacuum pumps can be used to adjust the corresponding sections of the negative pressure tube 403), causing the suction cups 401 that were originally adsorbing the glass surface to be installed to release, while simultaneously creating negative pressure inside the suction cups 401 near the other side of the glass, thus adsorbing the other side of the glass. This completes the switching of the suction surface; at this point, the glass surface to be installed faces outwards, facilitating subsequent installation.

[0035] After switching the suction surface, the suction cup 401, which was previously released from the installation surface, no longer adheres to the glass and moves away from the glass installation surface under the action of the corresponding automatic telescopic component 501. The mobile hanger 1 begins to move, moving the support member 4 that is adsorbing the glass along with it, and transporting the glass to above the vehicle window frame installation position.

[0036] Because the mounting surface of the vehicle window frame is angled, the operator adjusts the angle of the support component 4 and its suction cup 401 by operating the adjustment handle 402 on the support component 4, ensuring the glass fits snugly against the mounting surface of the vehicle window frame at a suitable angle. After the glass contacts the vehicle window frame, the electric vacuum pump gradually releases the negative pressure inside the suction cup 401, causing the suction cup 401 to release the glass, completing the installation of the glass on the vehicle window frame. Simultaneously, the operator can adjust the gap between the glass and the vehicle body to ensure the gap fit meets requirements. This effectively solves the problem of easy contamination around the glass caused by the need for manual glass flipping during installation in existing technologies, improving the efficiency and quality of glass installation.

[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
