Description

Technical Field

[0001] The utility model relates to the technical field of crane pipe devices, in particular to a bottom loading crane pipe for loading crude benzene onto a vehicle. Background Art

[0002] In the traditional crude benzene loading process, liquid hazardous chemicals such as crude benzene are loaded and unloaded through hoses. Although hoses are easy to use, they have great safety hazards and the loading and unloading environment is not friendly. In order to meet the dual needs of safety and environmental protection, crane pipes came into being. Crane pipes, also known as fluid loading and unloading arms, have the advantages of environmental protection, durability, resistance to strong acids and alkalis, etc. Therefore, they are widely used in the loading and unloading process of hazardous chemicals such as crude benzene.

[0003] However, during the process of loading crude benzene, the crane pipe needs to be disassembled and repaired regularly for safety reasons. However, when the crane pipe is disassembled and repaired, since the joints of the crane pipe are connected by flanges and other accessories in combination with a number of bolts, it is necessary to remove many bolts one by one to complete the disassembly, resulting in a cumbersome disassembly process for maintenance, which seriously affects work efficiency. Therefore, the present application specifically proposes a bottom-mounted crane pipe for loading crude benzene to solve the above problems. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a lower loading crane pipe for crude benzene loading, and the technical solution to the problem is that it includes a left crane pipe, characterized in that a right crane pipe is arranged correspondingly on the right side of the left crane pipe, the outer edge of the left crane pipe is fixedly connected with two left support rods arranged correspondingly in the upper and lower directions, the right crane pipe is fixedly connected with two right support rods arranged one by one corresponding to the left support rods, each of the right support rods is fixedly connected with a cross bar which is laterally slidably connected to the left support rod on the corresponding side, the left crane pipe is fixedly connected with a left support rod at the rear side of the outer edge, the right crane pipe is fixedly connected with a right support rod corresponding to the left support rod, the right support rod is rotatably connected with a cross shaft, the cross shaft is coaxially arranged with a screw threadedly connected to the left support rod, the left end of the cross shaft is coaxially fixedly connected with a rotating wheel, and the opposite ends of the left crane pipe and the right crane pipe are arranged with sealing structures.

[0005] Preferably, the sealing structure includes a left docking plate coaxially arranged with the right end of the left crane tube, a sealing groove is coaxially opened at the right end of the left docking plate, a sealing ring is mounted on the bottom of the sealing groove, a right docking plate is coaxially arranged with the left end of the right crane tube, and a sealing ring corresponding to the sealing groove is coaxially arranged with the left end of the right docking plate.

[0006] Preferably, the left end of each of the cross bars is fixedly connected with a blocking piece which movably abuts against the left end of the left support rod.

[0007] The beneficial effects of the utility model are:

[0008] When the present application is in use, the left crane pipe and the right crane pipe can be quickly disassembled and separated by rotating the horizontal axis. The horizontal axis is rotated clockwise, that is, the screw is rotated clockwise, and the screw can drive the right crane pipe to move close to the left crane pipe to facilitate the connection between the left crane pipe and the right crane pipe, and the sealing property of the connection between the left crane pipe and the right crane pipe can be ensured under the action of the sealing structure; correspondingly, the horizontal axis, that is, the screw, is rotated counterclockwise, so that the left crane pipe and the right crane pipe can be disassembled and separated. Compared with the traditional method that requires disassembly of many bolts to complete the disassembly and separation, the present application has a simple structure, is easy to operate, and is highly practical. It solves the problem that the disassembly process of traditional maintenance is relatively cumbersome and seriously affects work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following is combined with Figure 1-4 The specific implementation methods of the utility model are further described in detail.

[0016] Embodiment 1, the technical solution is that when the present application is in use, the left crane pipe 1 and the right crane pipe 2 can be quickly disassembled and separated by rotating the horizontal axis 8. The horizontal axis 8 is rotated clockwise, that is, the screw 9 is rotated clockwise, and the screw 9 can drive the right crane pipe 2 to move close to the left crane pipe 1 so as to facilitate the connection between the left crane pipe 1 and the right crane pipe 2, and the sealing property of the connection between the left crane pipe 1 and the right crane pipe 2 can be ensured under the action of the sealing structure; correspondingly, the horizontal axis 8, that is, the screw 9, is rotated counterclockwise, so that the left crane pipe 1 and the right crane pipe 2 can be disassembled and separated. Compared with the traditional method that requires the removal of many bolts to complete the disassembly and separation, the present application has a simple structure, is easy to operate, and is highly practical.

[0017] Embodiment 2, based on embodiment 1, specifically, when the present application is used, as shown in the accompanying drawings of the specification Figure 1 As shown, at this time, the left crane pipe 1 and the right crane pipe 2 are in a separated rotation state for the convenience of maintenance and repair. At this time, the horizontal shaft 8 connected to the right support rod 7 is rotated clockwise. In order to facilitate the rotation of the horizontal shaft 8, a rotating wheel 10 is provided. The horizontal shaft 8 rotates clockwise, that is, the screw rod 9 rotates clockwise. The clockwise rotation of the screw rod 9 will make the screw rod 9 spiral to the left relative to the left support rod 6. The spiral rotation of the screw rod 9 to the left will drive the right crane pipe 2 to move closer to the left crane pipe 1 through the right support rod 7. The left crane pipe 1 and the right crane pipe 2 are relatively arranged with a left support rod 3 and a right support rod 4, and the left support rod 3 and the right support rod 4 are slidably connected with a horizontal rod 5, which makes In the process of the screw 9 spiraling to the left and driving the right crane tube 2 to approach the left crane tube 1, with the cooperation of the sliding connection between the cross bar 5 and the left support rod 3, the right crane tube 2 can smoothly approach the left crane tube 1 along a straight line until the right docking plate 14 at the left end of the right crane tube 2 abuts against the left docking plate 11 of the left crane tube 1, and the sealing ring 15 and the sealing groove 12 are arranged in a plug-in form. When the right docking plate 14 at the left end of the right crane tube 2 abuts against the left docking plate 11 of the left crane tube 1, the sealing ring 15 is also inserted into the sealing groove 12 and pressed against the sealing ring 13, and then the sealing structure is also docked to ensure the sealing.

[0018] Correspondingly, the counterclockwise rotation of the horizontal axis 8 will cause the screw 9 to rotate counterclockwise synchronously, and the counterclockwise rotation of the screw 9 will spiral to the right relative to the left support rod 6. The spiral rotation of the screw 9 to the right cooperates with the restriction of the horizontal sliding connection between the cross bar 5 and the left bracket, which will cause the right crane pipe 2 to move linearly to the right synchronously. The right crane pipe 2 moves to the right and separates from the left crane pipe 1, thereby quickly completing the disassembly and separation of the left crane pipe 1 and the right crane pipe 2. The baffle 16 provided can limit the position to prevent the cross bar 5 from separating from the left support rod 3, ensuring that the left crane pipe 1 is separated from the right crane pipe 2 but not separated, but does not affect the overall maintenance.
