Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a new type of bottom-sweeping device for aviation kerosene tank trucks. Background Art

[0002] Based on the current bottom-sweeping operation inside the tank body of railway oil tank trucks at Dali Aviation Oil Distribution Center, research is carried out from aspects such as solving the long-term production and replacement of bottom-sweeping rakes, reducing the operation intensity, and improving the operation efficiency. The current situation is as follows: The existing bottom-sweeping rake for oil tank trucks is made of bamboo poles + rubber sheets by self-production.

[0003] In order to adapt to the length of the oil tank truck, relatively long bamboo poles are generally used. When in use, the operator stands beside the manhole at the top of the oil tank truck and holds the tail end of the bottom-sweeping rake to clean the bottom of the oil tank truck.

[0004] The existing bottom-sweeping rake for oil tank trucks is of a cantilever beam structure, and the tail end needs to be held manually by the operator, which brings two main problems:

[0005] 1. In order to fully scrape the entire oil tank truck, the existing bottom-sweeping rake for oil tank trucks is made long enough, so the force arm is very long and the manual operation is difficult.

[0006] 2. In order to reduce the overall weight for easy operation, bamboo poles are selected as the main body, but the characteristics of bamboo poles determine their insufficient rigidity. Therefore, the cleaning operation at the far end from the manhole is more difficult, and long-term production and replacement are required (about once every half month).

[0007] In order to overcome these disadvantages, the utility model provides a new type of bottom-sweeping device for aviation kerosene tank trucks. Content of the Utility Model

[0008] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a new type of bottom-sweeping device for aviation kerosene tank trucks is proposed.

[0009] In order to achieve the above purpose, the utility model adopts the following technical scheme: A new type of bottom-sweeping device for aviation kerosene tank trucks, including a sleeve, an insertion tube is inserted at the bottom end of the sleeve, a driving swing arm is arranged at the upper end of the sleeve, a terminal swing arm is arranged at the bottom end of the insertion tube, and a plurality of intermediate swing arms are arranged at the positions between the driving swing arm and the terminal swing arm on the outer sides of the sleeve and the insertion tube. The intermediate swing arms are rotatably connected to each other, between the intermediate swing arms and the driving swing arm, and between the intermediate swing arms and the terminal swing arm through hinges.

[0010] Further, a mounting seat is bolted at a position near the upper end of the sleeve, a second grip is bolted on the mounting seat, and a hook is fixedly connected to the upper end of the sleeve.

[0011] Further, the intermediate swing arm includes a first connecting seat, and a first connecting pipe and a second connecting pipe are respectively and fixedly connected to both ends of the first connecting seat.

[0013] Further, the active swing arm includes a second connecting seat, and a third connecting pipe and a first grip are respectively and fixedly connected to both ends of the second connecting seat.

[0014] Further, a second collar is rotatably connected inside the second connecting seat, and the second collar is bolted to the sleeve pipe.

[0015] Further, the end swing arm includes a third connecting seat, and a fourth connecting pipe and a fixing pipe are respectively and fixedly connected to both ends of the third connecting seat. A third collar is rotatably connected inside the third connecting seat, and the third collar is bolted to the bottom end of the insertion pipe.

The intermediate swing arms 3 are rotatably connected through hinges 10 between the intermediate swing arms 3, between the intermediate swing arm 3 and the active swing arm 4, and between the intermediate swing arm 3 and the end swing arm 5.

[0028] As Figures 1-4 shown, a mounting seat 21 is bolted to the position of the sleeve 1 near the upper end, a second grip 22 is bolted to the mounting seat 21, and a hook 23 is fixedly connected to the upper end of the sleeve 1. The device is hung on the manhole structure at the top of the oil tank truck through the hook 23, avoiding manual holding, and the operator does not need to hold it at any time.

[0029] As Figures 1-4 shown, the intermediate swing arm 3 includes a first connecting seat 8, a first connecting pipe 6 and a second connecting pipe 7 are respectively fixedly connected to both ends of the first connecting seat 8, a first collar 9 is rotatably connected inside the first connecting seat 8, and the first collar 9 is sleeved and connected to the sleeve 1 and the plug 2.

[0030] As shown Figures 1-4 in FIG. 1, the active swing arm 4 includes a second connecting seat 13. Both ends of the second connecting seat 13 are fixedly connected with a third connecting pipe 11 and a first grip 12 respectively. A second collar 14 is rotatably connected inside the second connecting seat 13, and the second collar 14 is bolted to the sleeve 1.

[0031] As shown Figures 1-4 in FIG. 2, the end swing arm 5 includes a third connecting seat 17. Both ends of the third connecting seat 17 are fixedly connected with a fourth connecting pipe 15 and a fixed pipe 16 respectively. A third collar 18 is rotatably connected inside the third connecting seat 17, and the third collar 18 is bolted to the bottom end of the insertion pipe 2. A rubber plate 19 is arranged at the bottom end of the fixed pipe 16, and a plurality of clamping clips 24 are arranged between the fixed pipe 16 and the rubber plate 19. The clamping clips 24 are bolted to the rubber plate 19.
