[0002] With the rapid development of rail vehicles, the demand for rail vehicles is further expanding. To meet the requirements of car body anti-corrosion and appearance, paint coating needs to be carried out on the car body surface.
[0003] The spraying site is a large painting booth established according to the spraying requirements of the car body. When the train car body is being painted, the height from the ground exceeds 4 meters. When spraying the roof, the paint workers need to climb onto the roof to complete the roof painting operation.
[0004] The traditional way to reach the top is to use a three-dimensional moving trolley inside the painting booth. Workers need to climb over the safety protection fence of the three-dimensional trolley and step on the top crossbar of the safety protection fence to reach the top. This way of reaching the top is very dangerous and there is a great risk of falling.

[0033] To make the objectives, technical solutions and advantages of the present utility model clearer and more obvious, the present utility model will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model
[0034] Refer to Figures 1 to 6 , this application example provides a climbing ladder for climbing onto the train roof in a paint spraying booth, including:
[0035] Upper track 6 and lower track 7 arranged oppositely
[0036] Support 1, the support 1 is slidably installed between the upper track 6 and the lower track 7
[0037] Climbing ladder 3, the lower end of the climbing ladder 3 is rotatably connected to the support 1, and the upper end is detachably connected to the support 1 through a connecting mechanism
[0038] Anti-falling cantilever 4, the anti-falling cantilever 4 is fixedly installed on the support 1, and an anti-falling device 41 for connecting with a hook fixed on the construction worker's body is installed on the anti-falling cantilever 4
[0039] For this climbing ladder for climbing onto the train roof 9 in the paint spraying booth, the support 1 uses the roller 2 to connect the upper track 6 and the lower track 7 of the original three-dimensional trolley. During use, the support 1 drives the climbing ladder 3 to slide to the position where climbing is required, thereby realizing the longitudinal free movement of the climbing ladder 3 along the vehicle body direction. The climbing ladder 3 and the support 1 are connected by the shaft 11. During use, first disconnect the connection between the connecting mechanism 8 and the climbing ladder 3, and rotate the climbing ladder 3 around the shaft 11, so that the climbing ladder 3 can be freely lowered and retracted, realizing the convenience and labor saving of the climbing ladder during use
[0040] The supporting wheel 2 is fixedly connected to the bracket 1 through bearings, sleeves and other components to ensure that the supporting wheel 2 can remain stable during rotation; the fixing method of the supporting wheel 2 and the bracket 1 may include bolt connection, welding or other reliable mechanical connection methods. When the bracket 1 is pushed by an external force, the supporting wheel 2 rolls or slides on the upper track 6 and the lower track 7, driving the bracket 1 to move along the track.
[0041] A standard fall arrester 41 is installed at the front end of the fall prevention cantilever 4 installed on the bracket 1. When the worker reaches the top, he connects the safety belt hook with the hook of the fall arrester 41. If the worker falls into the air when reaching the top, the fall arrester 41 can effectively prevent the risk of falling. After reaching the top, the worker connects the safety belt hook with the roof safety rope to complete the climb; when getting off the vehicle, the safety belt hook is separated from the roof safety rope and connected to the hook of the fall arrester 41. When the operator descends to the ground, the hook connected to the fall arrester 41 is released.
[0042] In the embodiment of the present application, the connecting mechanism 8 includes:
[0043] A chain, one end of which is fixedly connected to the bracket 1;
[0044] A latch, one end of which is connected to the other end of the chain, and the other end of which is inserted into or sleeved on a limiting member provided on the ladder 3.
[0045] Among them, the chain is welded to the middle part of the bracket 1 and is specifically set at a height that is convenient for the operator to operate; the limit piece is protrudingly welded on the side of the ladder 3; after the pin is inserted or sleeved on the limit piece, the chain is tightened, thereby limiting the relative position between the bracket 1 and the ladder 3. After the ladder 3 is tightened, it cannot rotate, thereby achieving the locking of the ladder 3.
[0046] Reference Figure 1 and Figure 2 The ladder for climbing to the top of the train roof 9 in the spray painting room also includes:
[0047] The brake mechanism 5 is fixedly mounted on the bracket 1 , and when the brake mechanism 5 comes into contact with the ground, it blocks the bracket 1 from sliding on the upper rail 6 and the lower rail 7 .
[0048] Reference Figure 2 The bottom of the climbing ladder in the embodiment of the present application has a brake mechanism 5, and the brake mechanism 5 includes:
[0049] A connecting arm 51, wherein the connecting arm 51 is fixedly connected to the bracket 1;
[0050] A screw rod 52, wherein the screw rod 52 is threadedly connected to the connecting arm 51;
[0051] A rubber block 53 is fixed to one end of the screw rod 51 facing the ground.
[0052] By rotating the screw rod 51, the rubber block 52 rubs against the ground to fix the bracket 1 relative to the ground.
[0053] When the climbing ladder reaches a specific position where it needs to reach the top, by rotating the screw rod 52 and the rubber block 53 installed at the bottom of the screw rod 52, when the screw rod 52 rotates towards the ground, the acoustic texture rubber block 53 at the bottom of the screw rod 52 contacts the ground, and sufficient friction is generated by the close fit of the rubber block 53 with the ground to fix the bracket 1 of the climbing ladder, and the climbing ladder can be effectively fixed to ensure that the painting worker can safely and conveniently climb onto the car roof.
[0054] Refer to Figure 3 and Figure 4 On the climbing ladder 3, a pedal 31 for construction workers to stand on is rotatably installed, and a flexible support member 32 in contact with the train car roof is also installed on the climbing ladder 3.
[0055] Wherein, when the connecting mechanism 9 connects the climbing ladder 3 and the bracket 1, the pedal 31 is supported by the flexible support member 32 to form a set angle with the climbing ladder 3.
[0056] The flexible support member is made of a material with rubber wrapped on its outer surface.
[0057] Such as Figure 4 After the contact connecting mechanism 9 is connected to the climbing ladder 3 and the bracket 1, manually hold the climbing ladder 3 and rotate it towards the train car roof 9; since the pedal 31 and the climbing ladder 3 are rotatably connected and the pedal 31 is supported by the flexible support member 32, when the climbing ladder 3 rotates, the bottom end of the pedal 31 first contacts the train car roof 9, and further the pedal 31 is erected on the train car roof 9; at the same time, a flexible support is formed between the flexible support member 32 and the outer surface of the train.
