Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to a horizontal shock-absorbing device for concrete pump pipes on a steel bar formwork floor. Background Technique

[0002] During the construction process, the concrete pouring of the steel bar formwork floor relies on concrete pump pipes for efficient transportation. When the concrete flows at a high speed in the pump pipes, it will cause strong vibrations of the pump pipes. This kind of vibration is transmitted along the pump pipes to the steel bar formwork floor system, seriously affecting the construction quality. Secondly, the vibration interferes with the precise positional relationship between the steel bars and the formwork, resulting in a reduction in construction accuracy and affecting the mechanical properties of the floor structure. Moreover, continuous vibration is likely to cause the loosening of formwork connectors, threatening the stability of the formwork system and even triggering serious accidents such as formwork bulging and bursting, endangering construction safety. Therefore, it is extremely urgent to develop a reliable horizontal shock-absorbing device for concrete pump pipes on a steel bar formwork floor.

[0003] However, the existing relevant horizontal shock-absorbing devices on the market have many defects. In terms of shock-absorbing components, most of them are simply designed and the spring structures are single, making it difficult to comprehensively and effectively consume and disperse energy during vibrations, resulting in unsatisfactory shock-absorbing effects. For the damping shock-absorbing mechanism, some devices are difficult to make full use of the principle of converting vibration mechanical energy into heat energy, and it is difficult to prevent the pump pipes from generating excessive displacements during vibrations. At the same time, when the pump pipes vibrate and drive related components to move, it is difficult to provide effective buffering, so that the vibration force is difficult to fully act on the shock-absorbing components, greatly weakening the overall shock-absorbing effect.

Hydraulic oil is provided inside the hydraulic cylinder 206. When the piston rod 207 inside the hydraulic cylinder 206 moves due to the vibrations of the pump pipe, the hydraulic oil will flow in the cylinder through the piston holes 208.

The first compression spring 203 matches the size of the first compression spring 203, so that it is convenient for the movable plate 301 to move randomly while the plurality of second compression springs 306 always exert force on the movable plate 301 when stretching and contracting.

By providing the threaded column 407, rotating the threaded column 407 can squeeze the third compression spring 406, thereby pushing the third compression spring 406 to move to constrain the pump pipe.

The inner wall of the extrusion pipe 213 is slidably connected to the surface of the fixed column 209. Two hydraulic holes 215 are formed at one end of the extrusion pipe 213. A hydraulic pipe 214 is fixedly connected to the surface of the fixed column 209. Hydraulic cavities 220 are formed at both ends of the hydraulic pipe 214. The surface of the extrusion pipe 213 is slidably connected to the inner wall of the hydraulic cavity 220. By the mutual cooperation of the extrusion pipe 213, the hydraulic pipe 214 and the hydraulic holes 215, it is convenient to generate damping when the lifting spring 216 pulls the sliding frame 212 to reset, thereby further consuming the vibration force of the pump pipe.

[0033] Please refer to Figure 4 , Further, a plurality of restraint grooves 307 are formed in the bottom surface of the movable plate 301. Movable beads 308 are rotatably connected to the inner walls of the restraint grooves 307. The surfaces of the plurality of movable beads 308 are all abutted against the inner bottom surface of the mounting frame 201. By the mutual cooperation of the restraint grooves 307 and the connection holes 304, when the pump pipe applies force to the movable plate 301, it is convenient for the movable plate 301 to slide back and forth or left and right according to the direction of the force of the pump pipe, so as to facilitate the movable plate 301 to fully apply the force to the second compression spring 306.

[0034] Please refer to Figure 4 , Further, a third compression spring 406 is fixedly connected to the side wall of the arc-shaped frame 405. The other end of the third compression spring 406 is fixedly connected to the side wall of the restraint frame 404. By providing the third compression spring 406, it is convenient for the restraint frame 404 and the third compression spring 406 to remain in an open state, so as to facilitate placing the pump pipe between the restraint frame 404 and the third compression spring 406.

The inner wall of the moving groove 309 is slidably connected to the moving plate 401. By providing the moving groove 309, it is convenient to slide and adjust the restrained pump pipe according to the on-site requirements, so as to facilitate the pump pipe to align with the pouring point.

By providing the fixed frame 403, it is convenient to adjust the pouring angle of the pump pipe, thereby improving the convenience of pouring.

[0038] Working principle: During use, through the provided restraint component 4, it is convenient to restrain the pump pipe, so that the vibration force of the pump pipe can fully act on the inside of the movable plate 301. By setting the threaded column 407, rotating the threaded column 407 can squeeze the third compression spring 406, thereby pushing the third compression spring 406 to move and restrain the pump pipe. Through the provided shock absorption component 2, when the concrete pump pipe vibrates, the first compression spring 203 and the stretching spring 216 will be compressed or stretched under the action of vibration, so that the vibration energy of the pump pipe is consumed and dispersed to a certain extent during the stretching and contracting process of the first compression spring 203 and the stretching spring 216, thereby reducing the vibration amplitude of the pump pipe and providing a preliminary buffer for shock absorption. There is hydraulic oil inside the hydraulic cylinder 206. When the vibration of the pump pipe causes the piston rod 207 inside the hydraulic cylinder 206 to move, the hydraulic oil will flow in the cylinder body through the piston hole 208. Due to the viscosity of the hydraulic oil, its flow will generate resistance, and this resistance can consume the vibration energy and convert the mechanical energy of vibration into the heat energy of the hydraulic oil, thereby playing a role of damping shock absorption and preventing the pump pipe from generating excessive displacement and vibration. By setting the stretching spring 216, the first compression spring 203, the hydraulic cylinder 206 and the piston rod 207 to cooperate with each other, the piston rod 207 provides an elastic restoring force, and the hydraulic cylinder 206 provides a damping force. The two complement each other to form an efficient shock absorption system, which can effectively reduce the vibration of the concrete pump pipe under different vibration conditions and protect the steel bar formwork floor structure. Through the provided buffer component 3, it is convenient to buffer when the vibration of the pump pipe drives the movable plate 301 to move, so as to avoid the force of the pump pipe vibration acting on the movable plate 301 directly acting on the mounting frame 201 through the movable plate 301. The first compression spring 203 matches the size of the first compression spring 203, so that it is convenient for the movable plate 301 to move randomly while multiple second compression springs 306 always act on the movable plate 301 during stretching and contracting, and then it is convenient for the multiple second compression springs 306 to decompose the force acting on the movable plate 301 and the movable plate 301 can automatically reset.
