Description

Technical Field

[0001] The utility model belongs to the technical field of spraying equipment, and in particular relates to an internal spraying device of an air cylinder. Background Art

[0002] Air cylinders are part of the auxiliary brake system in rail vehicles. Their function is to store air pressure and release pressure to drive the brake system when braking is required. Since the anti-corrosion performance of air cylinders is very important because they directly affect the performance and safety of the brake system, the inside of the air cylinders is sprayed with anti-rust oil or paint.

[0003] However, the air cylinder is a sealed container with narrow inlets and outlets. Conventional spraying cannot guarantee uniform spraying of the inside of the air cylinder, making it difficult to effectively implement the inner wall spraying operation of the cylinder.

[0004] Therefore, there is an urgent need for a device that can evenly and efficiently spray the inside of the air cylinder. Utility Model Content

[0005] In order to solve the problem in the prior art that the inside of the air cylinder cannot be sprayed evenly, the utility model provides an internal spraying device for an air cylinder. A guide wheel structure is arranged on a support frame to support and rotate the air cylinder, and the inside of the air cylinder is sprayed with a spray gun inserted therein.

[0006] The utility model provides an internal spraying device for an air cylinder, and the specific technical scheme is as follows, comprising: a support frame, a first guide wheel, a second guide wheel, a driving unit, and a spray gun;

[0008] The driving unit is used to drive the first guide wheel and the second guide wheel to drive the air cylinder to rotate and roll around the central axis;

[0009] The spray gun enters the interior from the end of the air cylinder, and evenly sprays the interior thereof under the rotating and rolling action of the air cylinder.

[0010] Preferably, the first guide wheel specifically includes: a first driving wheel and a first driven wheel; the second guide wheel specifically includes: a second driving wheel and a second driven wheel;

[0014] Preferably, the support frame is further provided with a transverse guide rail for adjusting the center distance between the first driving wheel and the first driven wheel, and the center distance between the second driving wheel and the second driven wheel.

[0015] Preferably, the support frame is also provided with a longitudinal guide rail for adjusting the center distance between the first guide wheel and the second guide wheel.

[0016] Preferably, the support frame is formed by welding structural parts.

[0017] Preferably, the bottom of the support frame is a hollow structure.

[0018] Preferably, the spray gun specifically comprises: an extended nozzle and a handle;

[0034] Please refer to Figures 1 to 3 , the technical scheme of the utility model is specifically described as a device for spraying the inside of an air cylinder, comprising: a support frame 1, a first guide wheel 2, a second guide wheel 3, a driving unit 4, and a spray gun 5;

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the support frame 1 serves as a support component of the entire air cylinder internal spraying device and provides an installation platform for the equipment. Therefore, on the top thereof, the first guide wheel 2 and the second guide wheel 3 are arranged in parallel with each other. When the first guide wheel 2 and the second guide wheel 3 abut against the cylindrical outer surface of the air cylinder, the air cylinder can be stably arranged on the support frame 1, so that the interior thereof can be sprayed conveniently.

[0036] The driving unit 4 is electrically connected to the first guide wheel 2 and the second guide wheel 3, converts electrical energy into mechanical energy, drives the first guide wheel 2 and the second guide wheel 3 to rotate, and then drives the air cylinder to rotate and roll around its central axis;

[0037] As the driving unit 4 drives the air cylinder to roll, the spray gun 5 enters the air cylinder from the air inlet and outlet pipe seat at the end of the air cylinder. Since the air cylinder itself is in a rotating state, the spray gun 5 only needs to remain stable inside the air cylinder to perform uniform spraying operations on the inside of the air cylinder.

[0038] As a preferred example, Figure 2 and Figure 3 As shown, as a supporting device of the air cylinder, the first guide wheel 2 specifically includes: a first driving wheel 21 and a first driven wheel 22; the second guide wheel 3 specifically includes: a first driving wheel 21 and a first driven wheel 22; more specifically, as Figure 3 In the present embodiment, the first driving wheel 21 and the second driving wheel 21 are both arranged at one side of the air cylinder, and are used to drive the air cylinder to rotate under the connection action of the driving unit 4 .

Through the controller, synchronous and differential rotation can be achieved according to actual needs.

[0041] As a preferred example, Figures 1 to 3 As shown, in the present embodiment, since the diameter size of the air cylinder has various styles, in order to adapt to the spraying operation of various air cylinders, a transverse guide rail 11 is further provided on the support frame 1. Through the adjustment function of the transverse guide rail 11, the center distance between the first driving wheel 21 and the first driven wheel 22, as well as the center distance between the second driving wheel 31 and the second driven wheel 32 can be adjusted to match the support of air cylinders with different diameter sizes; specifically, in the present embodiment, the specific structure of the transverse guide rail 11 is provided with a U-shaped groove structure, and the first guide wheel 2 and the second guide wheel 3 are fixed by bolt connection. In other embodiments, other forms such as slide rails can also be used to achieve it.

[0042] Further, such as Figures 1 to 3 As shown, in the present embodiment, since the length dimensions of the air cylinder also have various styles, in order to adapt to the spraying operations of various air cylinders, a longitudinal guide rail 12 is further provided on the support frame 1. Through the adjustment function of the longitudinal guide rail 12, the center distance between the first guide wheel 2 and the second guide wheel 3 can be adjusted; specifically, in the present embodiment, the specific structure of the transverse guide rail 12 is provided with a U-shaped groove structure, and the first guide wheel 2 and the second guide wheel 3 are fixed by bolt connection. In other embodiments, other forms such as slide rails can also be used.

[0043] As a preferred example, Figure 1 and Figure 2 As shown, in order to provide more stable and reliable support for the spraying equipment and the air cylinder itself, in this embodiment, the support frame 1 is formed by welding structural parts, specifically, by welding steel structural parts, which can reduce the production cost of the device while providing a stable support effect.

[0044] Further, such as Figure 1 and Figure 2 As shown, in this embodiment, the bottom of the support frame 1 is a hollow structure, and a fixing piece can be provided to place the unpainted air cylinder to be produced, thereby improving the production efficiency of the spraying inside the air cylinder.

[0045] As a preferred example, Figure 1 and Figure 2 As shown, in this embodiment, the specific structure of the spray gun 5 includes: an extended nozzle 51 and a handle 52;

[0046] The extended nozzle 51 enters the interior of the air cylinder through the air inlet and outlet pipe seat at the end of the air cylinder, and sprays the interior of the air cylinder under the control of the handle 52.

[0047] Furthermore, in this embodiment, the extended nozzle 51 and the handle 52 are detachably connected to accommodate air cylinders of different lengths for spraying.

[0048] Further, if Figure 1 As shown, in this embodiment, a feed port 53 is also provided at the bottom of the handle 52, and the feed port 53 can be connected to different raw materials, such as paint, anti-rust oil, etc. The anti-corrosion type of the inner wall of the air cylinder is determined according to the customer's drawing requirements and sprayed to meet customer customization needs.
