Problems solved by technology

[0004] 1. During the repair process, the top rod needs to be always supported on the floor of the car, occupying space such as aisles and affecting the passage of personnel or other tools
[0005] 2. The length of the top rod is long, if it is accidentally touched during the repair process, there is a danger of falling over, which will affect the safety of the repair work
[0006] 3. When the top roller is supported between the floor and the roof of the car, due to the length of the top roller, it is difficult to place the top roller vertically, which will lead to uneven force on the contact between the top roller and the roof, and tightness of the top roller. The effect is poor, and the repair effect of the glue-opened part of the roof is not ideal, and it will also affect the efficiency of the repair work and the appearance of the repaired roof

Embodiment 1

[0047] like Figure 1 to Figure 3 As shown, the present invention provides a vehicle interior roof panel repairing device, which is used for the repairing operation of the vehicle interior roof panel 1 at the splicing seam.

[0048] The repair device includes a support beam 2, the support beam 2 is installed across the carriage on the vehicle body side roof frame 3 inherent in the vehicle body itself at both ends, and a plurality of jacking devices 4 are movably installed on the support beam 2 to facilitate the The operator adjusts the positions of the jacking points of the plurality of jacking devices 4 according to the working position. The support beam 2 is fixedly installed just below the glue opening and repairing position during operation, so as to ensure that the jacking device 4 is pressed against the glue opening position on the interior roof 1 from the bottom up. After re-applying the glue on the opening of the interior roof panel 1, use the jacking device 4 to pres...

Embodiment 2

[0079] The difference from the first embodiment is that when there is no suitable fixing point on the vehicle body side roof frame 3, in this embodiment, preferably, the two support rods 21 are disassembled and fixed respectively, and the ends of each support rod 21 are respectively fixed. By connecting the mounting seat 5 with the vehicle body side roof frame 3, it is only necessary to ensure that the two support rods 21 are parallel. It is helpful to reduce the difficulty of operation and improve the efficiency of operation.

[0080] At this time, the length of the connecting plate 7 between the two support rods 21 can be adjusted, and the length of the connecting plate 7 can be adjusted according to the distance between the two support rods 21 . Of course, the connecting plates 7 of different lengths can also be selected for fixed installation according to the distance between the two support rods 21 .

Embodiment 3

[0082] The difference from the first embodiment is that in this embodiment, the detachable connection structure between the top tightening device 4 and the connecting plate 7 is preferably adopted, and the T-shaped sliding pair (in the figure) is passed between the top tightening device 4 and the connecting plate 7. Not shown) to achieve detachable connection, the sliding direction of the T-shaped sliding pair is the same as the extending direction of the support rod 21 .

[0083] Specifically, the mounting part at the top of the main body 41 of the jacking device 4 has a T-shaped slider protruding upward, a T-shaped sliding groove is provided on the lower surface of the connecting plate 7, and the T-shaped slider on the main body 41 is from one side. Insert into the T-shaped chute of the connecting plate 7 to realize the connection between the top tightening device 4 and the connecting plate 7, and then fix the top tightening device 4 and the connecting plate 7 through the top...

Abstract

The invention relates to an in-vehicle top plate repairing device and a glue failure repairing method, the repairing device comprises a supporting beam, the supporting beam stretches across a carriage and is installed on vehicle body side top frameworks at the two ends, and a plurality of jacking devices are movably installed on the supporting beam and upwards jack the in-vehicle top plate from the lower direction. The method comprises the steps that S1, the glue failure position of the roof in the vehicle is cleaned and re-glued; s2, supporting beams provided with a plurality of jacking devices are erected on the vehicle body side jacking frameworks at the two ends, and the supporting beams are fixed to the positions under the glue failure positions; s3, the multiple jacking devices are moved to proper operation positions correspondingly; s4, the jacking devices are operated respectively, the jacking height of the corresponding position is adjusted according to the height from the jacking point to the supporting beam, and the jacking end is made to abut against the top plate in the vehicle; s5, the jacking state is kept until the sealant curing design time is reached; and S6, after the set time is up, the repairing device is dismounted. The device does not occupy the space in the vehicle, can guarantee the jacking effect with the top plate in the vehicle, guarantees the operation quality, and improves the operation efficiency.

Description

technical field [0001] The invention belongs to the technical field of vehicle repairing equipment, and particularly relates to a vehicle interior roof repairing device and a glue-opening repairing method. Background technique [0002] In the repairing process of the inner roof of rail vehicles such as EMUs, the top roller whose length can be adjusted is generally used, and the top roller is placed between the floor and the roof in the car. Top tight. [0003] The above-mentioned process of using the top roller to open and repair the top plate has the following disadvantages: [0004] 1. During the repair process, the top stick should always be supported on the floor of the vehicle, occupying space such as aisles and affecting the passage of personnel or other tools. [0005] 2. The length of the top stick is long. If it is accidentally touched during the repair process, there is a danger of dumping, which affects the safety of the repair operation. [0006] 3. When the t...
