Description

Technical Field

[0001] The present invention relates to the field of removing sealant from urban rail vehicles. Specifically, it relates to a device for removing sealant from the side wall of urban rail vehicles. Background Art

[0002] For the windows and honeycomb panels of urban rail vehicles, polyurethane bonding sealant is usually used to fill and seal the edge gaps. At present, the main methods for removing sealant from urban rail vehicles include using handheld cutting machines, utility knives, customized tools, glue shovels, and chemical degumming.

[0003] The prior art includes degumming devices. For example, Chinese Patent No. CN217251519U discloses a frame degumming device, which is characterized by a cylindrical wall with a hollow structure having an upward open surface, filled with sulfuric acid inside to remove the colloid by heating and corrosion; another example is Chinese Patent No. CN217411631U, which discloses an electric degumming device, which is characterized by manually operating a button to make the motor rotate forward and backward to drive the degumming needle on the coupling to rotate clockwise and counterclockwise to facilitate the cleaning of the colloid. However, the existing degumming devices cannot be applied to the degumming of windows of subways and urban rail vehicles.

[0004] Taking a certain subway project as an example, the existing method for removing sealant from subway windows is to first use a cutting machine to separate the main body of the sealant from the substrate, and then use a utility knife and a U-shaped degumming knife to remove the sealant. This method has problems such as large vibration of the cutting head of the cutting machine, easy damage to the glass, high physical consumption of the operators, easy damage to the paint on the frame by the utility knife, and high cost due to fast wear of the cutting head and the body of the cutting machine, and cannot be carried out continuously.

[0005] In view of the problems in the related art, no effective solution has been proposed yet. Summary of the Invention

[0006] In view of the problems in the related art, the present invention provides a device for removing sealant from the side wall of urban rail vehicles to overcome the above technical problems existing in the prior art.

[0012] Furthermore, in order to make subtle adjustments to the position of the slide rail and thereby ensure accurate removal of the sealant, the slide rail fine-tuning mechanism includes a bolt connection frame arranged on the side of the bracket, a fine-tuning bolt is connected to the bolt connection frame, and one end of the fine-tuning bolt extends to the side of the slide rail plate.

[0013] Furthermore, in order to provide rotational force to the screw rod, one end of the screw rod close to the lower hook claw extends to the bottom of the bearing seat and is connected to a crank.

[0014] Furthermore, in order to automatically destroy the sealant, complete the removal of the window sealant, and realize manual control of the motor and the milling cutter head to labor-saving, safe and rapid removal of the sealant in the gap on the side wall, the sealant removal mechanism is arranged on the motor on the side wall of the motor mounting plate, and a milling cutter head is arranged on the output shaft of the motor; when the milling cutter head removes the sealant, the gap between the milling cutter head and the sealant is 1mm.

[0015] Furthermore, in order to confirm that the milling cutter head is completely aligned with the sealant, the centering device includes a centering plate arranged in the middle of the slide rail, and both ends of the centering plate are slidably connected to the slide rail, and a center pointer is arranged in the middle of the centering plate.

[0016] Further, in order to prevent the bracket from damaging the paint on the contact surface and to increase the friction, a soft block is provided on the side of the bracket away from the slide rail plate, and the material of the soft block is rubber.

[0017] The beneficial effects of the present invention are as follows:

[0018] (1) The urban rail vehicle side wall sealant removal device of the present invention can enable the milling cutter head to move stably along the sealant direction, saving effort, being safe and fast in removing the urban rail vehicle side wall sealant.
