Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline handling racks, and particularly relates to a pipeline handling rack for highway engineering. Background Technique

[0002] In highway engineering, pipeline handling racks are usually used to facilitate the manual transportation and installation of drainage pipes, drainage ditches, ventilation pipes and other related pipeline facilities in some restricted spaces. These handling racks play an important role in highway engineering.

[0003] The existing pipeline handling racks for highway engineering have the following disadvantages during use:

[0004] Generally, two structures for clamping the two ends of the pipeline are set to clamp and fix the two ends of the pipeline, and then the pipeline is lifted from the ground through a lifting structure, and then moved and transported. However, the distance between the above two clamping structures is not convenient to adjust, and it is impossible to drive the clamping or loosening simultaneously through a single driving structure, resulting in the need to operate the two clamping structures separately when clamping, which is very inconvenient to use. Therefore, a pipeline handling rack for highway engineering is needed. Content of the Utility Model

[0009] As a preferred embodiment, both of the clamping structures include a transmission shaft rotatably connected to the side wall of the vertical plate away from the n-shaped moving frame through a bearing seat. A worm is fixedly connected to the bottom end of the transmission shaft. Worms are meshed and connected to both sides of the worm. A rotating shaft is fixedly connected to the installation shaft hole of each worm gear. One end of each rotating shaft is rotatably connected to the outside of the vertical plate, and an arc-shaped clamping arm for clamping and fixing the pipeline is fixedly connected to the other end of each rotating shaft.

[0014] In the present utility model, when using the pipe handling rack for highway engineering, the distance between the two clamping structures can be adjusted according to the length of the pipe. By loosening the two hand-tightening screws, the two adjusting plates can be manually moved away from each other or towards each other in the adjusting channels respectively, so that the distance between the two clamping structures can be adjusted. After the adjustment is completed, the two hand-tightening screws can be locked. Thereafter, by starting the double-shaft motor, the two spline sleeves drive the corresponding spline shafts to rotate respectively, so that the two bevel gears a rotate in the same direction at the same time, and drive the two bevel gears b in different directions respectively.

[0023] Embodiment

[0024] Generally, two structures for clamping both ends of the pipeline are provided to clamp and fix both ends of the pipeline, and then the pipeline is lifted from the ground through a lifting structure and then moved and carried. However, the distance between the above two clamping structures 5 is not convenient to adjust, and it is impossible to drive the clamping or loosening simultaneously through a single driving structure, resulting in the need to separately operate the clamping of the two clamping structures 5, which is very inconvenient to use;

[0025] For this reason, please refer to Figures 1-4 , the present utility model provides a pipeline handling rack for highway engineering, including: an n-shaped moving rack 1, roller a 2 is rotatably connected to both side walls of the n-shaped moving rack 1, a cross-shaped plate 4 is connected to the n-shaped moving rack 1 through a lifting transmission structure 3, two symmetrically arranged adjustment channels are opened at the top of the cross-shaped plate 4, an adjustment plate 41 with a convex cross-section is slidably arranged in each adjustment channel, vertical plates 42 are fixedly connected to the bottoms of the two adjustment plates 41 facing away from each other, clamping structures 5 are installed on the vertical plates 42, connecting frames 43 are fixedly connected to both side walls of the two vertical plates 42, roller b 44 is rotatably connected to the connecting frames 43, screw holes are opened on both side walls of the cross-shaped plate 4, hand-tightening screws 45 are threadedly connected to the screw holes, and the ends of the hand-tightening screws 45 are tightly pressed against the outside of the adjustment plate 41 after being locked;

[0026] The screw holes are all communicated with the adjustment channels;

[0027] It further includes a linkage synchronous driving structure 6, which is installed on the top of the cross-shaped plate 4 and is connected to the tops of the two clamping structures 5 and the two adjustment plates 41.

[0028] Further, as Figures 1-2As shown, it is worth specifically stating that the lifting drive structure 3 includes two lifting plates 32 fixedly connected to the bottom end of the cross-shaped plate 4. The bottom ends of the lifting plates 32 are both movably inserted into the top of the n-shaped moving frame 1. An electric hydraulic cylinder 31 fixedly connected to the inner top wall of the n-shaped moving frame 1 is provided between the two lifting plates 32. The telescopic end of the electric hydraulic cylinder 31 movably penetrates through the inner top wall of the n-shaped moving frame 1 and is fixedly connected to the middle of the bottom end of the cross-shaped plate 4.

[0029] The top of the n-shaped moving frame 1 is provided with a lifting channel for the lifting plate 32 to cooperate with.

[0030] Furthermore, as Figures 1-4 shown, it is worth specifically stating that both clamping structures 5 include a transmission shaft 51 rotatably connected to the side wall of the vertical plate 42 away from the n-shaped moving frame 1 through a bearing seat. A worm 52 is fixedly connected to the bottom end of the transmission shaft 51. Worms 53 are meshed and connected to both sides of the worm 52. A rotating shaft 54 is fixedly connected to the inner mounting shaft hole of each worm 53. One end of each rotating shaft 54 is rotatably connected to the outside of the vertical plate 42, and an arc-shaped clamping arm 55 for clamping and fixing the pipe is fixedly connected to the other end of each rotating shaft 54.

[0031] The thread directions of the two worms 52 are opposite;

[0032] Furthermore, as Figures 1-4 shown, it is worth specifically stating that the linkage synchronous drive structure 6 includes a double-shaft motor 61 fixedly connected to the middle of the top end of the cross-shaped plate 4. Spline sleeves 62 are fixedly connected to both output shafts at both ends of the double-shaft motor 61. The ends of the spline sleeves 62 away from the double-shaft motor 61 are both rotatably connected to the top end of the cross-shaped plate 4 through n-shaped bearing seats. Spline shafts 63 adapted to each other are movably installed in the mounting shaft holes of the two spline sleeves 62. One ends of the two spline shafts 63 away from each other are rotatably connected to the top of the adjusting plate 41 through bearing seats. Extension parts at one ends of the two spline shafts 63 away from each other are fixedly connected with bevel gears a64. Bevel gears b65 are meshed and connected below the bevel gears a64. The bevel gears b65 are fixedly connected to the outer sides of the top ends of the transmission shafts 51.

[0033] Among them, the spline shaft 63 can perform telescopic movement in the spline sleeve 62, similar to the principle of a telescopic rod. However, when the spline sleeve 62 rotates, it can drive the spline shaft 63 to rotate.

[0034] In summary, when using the pipe handling rack for highway engineering, the distance between the two clamping structures 5 can be adjusted according to the length of the pipe. By loosening the two hand-tightening screws 45, the two adjusting plates 41 can be manually moved away from each other or towards each other in the adjustment channels respectively, so that the distance between the two clamping structures 5 is adjustable. After the adjustment is completed, the two hand-tightening screws 45 can be locked. Thereafter, by starting the double-shaft motor 61, the two spline sleeves 62 drive the corresponding spline shafts 63 to rotate respectively, so that the two bevel gears a64 rotate in the same direction at the same time and drive the two bevel gears b65 in different directions. Since the thread helix directions of the two worms 52 are opposite, the two worms 52 can drive the worm wheels 53 arranged on both sides, so that the arc-shaped clamping arms 55 connected to each rotating shaft 54 can easily clamp the pipe. Then, by starting the electric hydraulic cylinder 31, the cross-shaped plate 4 is pushed upward, so that the clamped and fixed pipe is lifted. With the arrangement of the roller a2 and the roller b44, it is convenient for manual rapid handling of the pipe in a restricted space, greatly improving the convenience during handling.
