Description

Technical Field

[0001] The utility model relates to the technical field of railway special oxygen cylinder loading and pushing trolleys, in particular to a railway special oxygen cylinder safe loading and pushing trolley. Background Art

[0002] During railway operations, oxygen and acetylene are often used for cutting and other maintenance work on rails and train cars. This requires transporting oxygen cylinders to the maintenance site for these operations. Oxygen is primarily stored and transported in steel cylinders. Because steel cylinders are heavy, handling them often requires the combined efforts of multiple personnel, making them impossible for a single person to accomplish.

[0003] The utility model with the prior art publication number CN207128962U relates to an oxygen cylinder pushing trolley, comprising a cylinder supporting horizontal plate and two vertical support beams fixed on the left and right sides of the cylinder supporting horizontal plate. A front support leg is provided on the front side of the cylinder supporting horizontal plate, and a rear caster is provided on the rear side of the cylinder supporting horizontal plate; a horizontal support leg is provided on the side of each vertical support beam away from the cylinder supporting horizontal plate, and a caster is provided on the end of the horizontal support leg away from the vertical support beam; at least one semicircular cylinder support ring is provided across the two vertical support beams, and each cylinder support ring protrudes toward one side of the horizontal support leg; a cylinder tightening belt is provided across the two vertical support beams, and the cylinder tightening belt is located on the side away from the horizontal support leg. When using the oxygen cylinder pushing trolley provided by the utility model, the oxygen cylinder can be pushed horizontally or vertically, which is convenient for pushing in different situations, especially for pushing up and down slopes, and the oxygen cylinder is firmly fixed;

[0004] However, when it is performing railway operations, the rollers installed at the bottom are conventional circular rollers and the entire device structure is relatively complex, resulting in the device being heavy and unable to fit into the rails. This makes it impossible for the device to travel on the rails and therefore impossible to use during railway operations.

[0005] Therefore, it is necessary to provide a railway special oxygen cylinder safe loading and pushing trolley to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a railway-specific oxygen cylinder safe loading and transporting trolley.

[0007] A safety loading and pushing trolley for railway special oxygen cylinders provided by the utility model comprises two chassis, which are connected by a rotating hinge. Two connecting plates are fixedly connected to both sides of the lower ends of the two chassis. A roller is rotatably connected between the two connecting plates at the lower end of the same chassis. Connecting blocks are installed on both sides of one end of the two chassis facing each other through bolts. Two connecting blocks on the same chassis on one side are jointly connected to a transmission frame. Two connecting blocks on the side far from the transmission frame are jointly connected to a support frame. A semi-circular bracket is fixedly connected to the upper end of the support frame. Two support columns are fixedly connected to the upper end inside the transmission frame. A pipe support is welded to the lower end inside the transmission frame. Two support plates are installed inside the pipe support.

[0008] Preferably, the two rollers are in the shape of a boss with a diameter gradually increasing from the center to both ends, so as to fit the railway track and prevent derailment when it travels on the surface of the railway track.

[0009] Preferably, the longitudinal section of the support frame is in the shape of a "day" character inclined at 90°.

[0010] Preferably, the angle between the bracket and the pipe support and the chassis is inclined downward at 45°, which is used to enhance the stability of the oxygen cylinder during movement.

[0011] Preferably, the two support plates are welded inside the pipe support on the side far from the support frame in a "cross" shape.

[0012] Preferably, fixed pipes are fixedly connected to both sides of one end where the two chassis are connected to each other. A fixed pin is threadedly connected between every two fixed pipes on the same side.

[0013] Compared with the related technology, a safety loading and pushing trolley for railway special oxygen cylinders provided by the utility model has the following beneficial effects:

[0014] The utility model provides a safety loading and pushing trolley for railway special oxygen cylinders. When specifically implemented:

[0015] 1. Place the mouth of the oxygen cylinder on the surface of the bracket and insert the bottom of the cylinder into the pipe support. The whole oxygen cylinder is placed with the mouth upward and inclined at 45° above the device. The relatively connected boss-shaped rollers can adapt to the shape of the railway track, so that the device can travel on the surface of the railway track without derailment, and can participate in railway transportation, greatly reducing the trouble of railway workers transporting oxygen cylinders, and having a wider range of applications;

[0016] 2. The transmission frame and the support frame can be removed by removing the nuts on the surface of the bolts. By removing the fixed pins, the two chassis can be rotated around the rotating hinge in the middle for folding, thereby reducing the volume of the device during storage and transportation and making it more convenient to use.

[0022] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0023] Please refer to Figure 1 - Figure 4 ,in, Figure 1 This is an axonometric diagram of a railway-specific oxygen cylinder safe loading and transporting trolley provided by the utility model; Figure 2 This is an axonometric diagram of a railway-specific oxygen cylinder safe loading and transporting trolley provided by the utility model; Figure 3 This is a front view of a railway-specific oxygen cylinder safe loading and transporting trolley provided by the utility model; Figure 4 The utility model provides a top view of a railway-specific oxygen cylinder safe loading and transporting trolley.

[0024] In the specific implementation process, Figure 1 - Figure 4As shown, a railway-specific oxygen cylinder safe loading and transporting trolley includes two chassis 1, which are connected by rotating hinges. Connecting plates 2 are fixedly connected on both sides of the lower ends of the two chassis 1. A roller 3 is rotatably connected between the two connecting plates 2 located at the lower ends of the same chassis 1. Connecting blocks 5 are installed on both sides of the opposite ends of the two chassis 1 through bolts 4. The two connecting blocks 5 located on the same chassis 1 on one side are commonly connected to a transmission frame 6. The two connecting blocks 5 on the side away from the transmission frame 6 are commonly connected to a support frame 7. The upper end of the support frame 7 is fixedly connected to a semicircular bracket 8. The inner upper end of the transmission frame 6 is fixedly connected to two support columns 9. The inner A tube 10 is welded to the lower end, and two support plates 11 are installed inside the tube 10. The two rollers 3 are in the shape of a boss with a diameter gradually increasing from the center to both ends. The longitudinal section of the support frame 7 is in the shape of a "sun" inclined at 90°. The bracket 8 and the tube 10 are inclined downward at 45° to the base frame 1. The two support plates 11 are welded in the shape of a "cross" on the side of the tube 10 away from the support frame 7. The two base frames 1 are connected to each other with fixed tubes 12 on both sides of one end. A fixing pin 13 is threadedly connected between every two fixed tubes 12 on the same side. The two support columns 9 can not only enhance the stability of the transmission frame 6, but also provide a fulcrum for the power to move the device.

[0025] The working principle provided by the utility model is as follows: when using the device, the device is placed on the surface of the rails so that the roller 3 is aligned with the rails on both sides, the mouth of the oxygen cylinder is placed on the surface of the bracket 8, and the bottom of the bottle is inserted into the inside of the bracket 10. The entire oxygen cylinder is placed above the device with the mouth of the bottle tilted upward at 45°, and the device and the oxygen cylinder on its surface are driven to be moved and transported by pushing and pulling the transmission frame 16. When the device is not needed or needs to be moved a long distance away from the rails, the nut on the surface of the bolt 4 can be removed to remove the transmission frame 6 and the support frame 7. By removing the fixing pin 13, the two base frames 1 can be rotated around the middle rotating hinge to fold, thereby reducing the volume of the device during storage and transportation.
