Description

[0002] When pouring concrete in high-rise buildings of housing construction projects, it is necessary to transport it to the pouring site by concrete pump trucks. When transporting concrete, the pump pipe of the concrete pump needs to pass through the already poured floor slab, and the pump pipe has a large vibration, which will cause damage to the pump pipe, floor slab, etc. For this reason, the concrete pump pipe needs to be reinforced.

[0003] There are many reinforcement methods available at present. Most of them use clamps to clamp and then lock with bolts. Some also use the traditional method of wooden reinforcement. The main stress point of the former is on the bolts of the locking clamps. The bolts that are stressed for a long time are prone to stripping and damage, causing loosening. Once loosening occurs, it will only become more serious. The latter not only requires a large amount of square wood, but also cannot effectively fix the pump pipe, resulting in excessive vibration of the pump pipe and low stability, affecting production efficiency.

[0039] like Figure 5-Figure 9 As shown, in order to facilitate the limit block 32 to enter and exit the limit groove 25, a lifting block 26 is vertically movably connected to the inner side of the limit groove 25, and a column 24 extending to the top of the driving plate 11 is vertically fixed on the top of the lifting block 26, and the column 24 is matched with the movable guide of the driving plate 11, and a through groove 42 corresponding to the column 24 is provided on the inner shell cover 7, and the upper end of the column 24 extends to the top of the inner shell cover 7 through the through groove 42, and a force head 16 is provided on the top of the column 24, and a flange 28 is fixedly provided on the outer side of the lower end of the column 24, and a first spring 27 is provided between the bottom of the positioning plate 18 and the top of the driving plate 11, and when the first spring 27 is in the initial state, the lifting block 26 is located at the inner upper end of the limit groove 25.

[0040] like Figure 1-Figure 6 , Fig.13As shown, a driving assembly for driving the column 24 to move downward and the compound gear ring 17 to rotate is provided on the outer side of the inner shell cover 7, and the driving assembly includes a second rotating shaft 39 arranged on the side wall of the inner shell cover 7, the second rotating shaft 39 is vertically arranged, and the second rotating shaft 39 is rotatably connected to the side wall of the inner shell cover 7, and the number of the second rotating shaft 39 is at least four, and a second gear 15 is provided on the top of the second rotating shaft 39, and a first gear 10 is provided on the bottom of the second rotating shaft 39, and one side of the first gear 10 extends to the inner side of the inner shell 6 and meshes with the outer gear teeth of the compound gear ring 17. Specifically, a groove 38 corresponding to the first gear 10 is provided on the lower end side wall of the inner shell 6, and one side of the first gear 10 extends to the inner side of the inner shell 6 through the groove 38. The top of the inner shell cover 7 is rotatably connected to the first rotating shaft 13 corresponding to the second gear 15, and the upper end of the first rotating shaft 13 extends to the positioning outer shell 2 At the top, an incomplete gear 12 is fixedly provided at the lower end of the first rotating shaft 13, a bolt head 4 is fixedly provided at the upper end of the first rotating shaft 13, an outer gear ring 8 is rotatably connected to the top inner periphery of the inner shell cover 7, a driving ring 9 is fixedly provided at the top of the outer gear ring 8, a driving bar 14 corresponding to the force-bearing head 16 is fixedly provided at the bottom of the driving ring 9, one end of the driving bar 14 is a slope, and is configured so that when the lowest end of the driving bar 14 corresponds to the top of the force-bearing head 16, the bottom of the lifting block 26 is not lower than the top of the inner cavity of the slide groove 23, the incomplete gear 12 is intermittently meshed with the outer gear ring 8 and the second gear 15, and is configured so that when the incomplete gear 12 is separated from the second gear 15, the positioning plate 18 just clamps the pump tube 3 firmly, and the incomplete gear 12 is meshed with the outer gear ring 8 again after being separated from the second gear 15, and the incomplete gear 12 is meshed with the second gear 15 again after being separated from the outer gear ring 8.

[0041] Working principle: when in use, a through hole 5 is opened on the concrete floor 1 in advance, and then the positioning shell 2 is fixedly installed on the periphery of the through hole 5 on the top of the concrete floor 1 by bolts, and then the pump pipe 3 is inserted, and then the pump pipe 3 is positioned. Specifically, the bolt head 4 is screwed at the same time by a wrench or other tools, and the bolt head 4 drives the incomplete gear 12 to rotate through the first rotating shaft 13. At this time, the force head 16 and the lowest end of the driving bar 14 are in a state of conflict, and the incomplete gear 12 first meshes with the second gear 15, so that the second gear 15 drives the first gear 10 to rotate, and the first gear 10 drives the compound gear ring 17 to rotate, and the compound gear ring 17 drives the third gear 20 to rotate, and the third gear 20 drives the screw rod 30 to rotate, and the screw rod 30 drives the screw rod 30 to rotate. The rod 30 drives the moving frame 19 to move in the direction of the pump tube 3, and the eight moving frames 19 respectively drive the reinforcement plate 29 and the positioning plate 18 to move in the direction of the pump tube 3, wherein the first sliders 31 at the tops of the four moving frames 19 slide in the slide grooves 23 at the bottom of the driving plate 11, and then the positioning plate 18 clamps the pump tube 3, and the reinforcement plate 29 clamps the outer sides between the adjacent positioning plates 18, and then the incomplete gear 12 separates from the second gear 15, and after separation, it meshes with the outer gear ring 8, thereby driving the outer gear ring 8 to rotate, and the outer gear ring 8 drives the driving ring 9 to rotate synchronously, and the driving ring 9 drives the multiple driving strips 14 to rotate, and the driving strips 14 will gradually separate from the force-bearing head 16, and the first spring 27 will gradually reset under the action of the slope, and the lifting block 26 It gradually rises, and then the third spring 37 resets and drives the limit block 32 to enter the limit groove 25, and then stops rotating the bolt head 4. At this time, fixation is achieved. When the pump tube 3 vibrates and applies pressure to a certain positioning plate 18 and reinforcement plate 29, the positioning plate 18 and reinforcement plate 29 will apply pressure to the moving frame 19, and the moving frame 19 will act on the screw rod 30. Once the screw rod 30 tends to slip or be damaged, the corresponding moving frame 19 will push the driving plate 11 through the limit block 32. The driving plate 11 tends to move outward. Under the action of the guide groove 21 and the guide shaft 22, the driving plate 11 can make its two adjacent driving plates 11 tend to move toward the direction of the pump tube 3, so that the two adjacent driving plates 11 will drive the corresponding reinforcement plates 29 Applying greater pressure to the positioning plate 18 prevents the pump tube 3 from loosening due to excessive pressure in a certain direction, and plays a secondary reinforcement role. When disassembling, the bolt head 4 is rotated in the opposite direction, and the incomplete gear 12 is first meshed with the outer gear ring 8, and the driving bar 14 first presses down the column 24 through the force head 16, so that the lifting block 26 pushes the limit block 32 out of the limit groove 25, and then the incomplete gear 12 is meshed with the second gear 15, and the second gear 15 drives the compound gear ring 17 to rotate through the first gear 10, so that the screw 30 is reversed, and the positioning plate 18 and the reinforcement plate 29 are all displaced and reset. Finally, the pump tube 3 is disassembled and then the positioning housing 2 is disassembled. The device is fixed firmly, avoiding loosening and reducing the noise caused by loosening.

[0042] It should be noted that when the positioning plate 18 and the reinforcement plate 29 are in a clamping state, the movable block 34 is hidden in the movable groove 36. When the drive plate 11 tends to move outward, the two adjacent drive plates 11 tend to move inward, thereby pushing the reinforcement plate 29 to squeeze the positioning plate 18. The movable block 34 and the movable groove 36 can ensure that the reinforcement plate 29 and the positioning plate 18 have space to move in the direction of the pump tube 3, thereby increasing the degree of tightening of the reinforcement plate 29 to the positioning plate 18.

[0043] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
