[0002] In structural engineering, when the concrete pouring height is relatively high, the concrete is generally poured by means of pumping, which requires laying pump pipes for transporting concrete in advance. During the laying process of the pump pipes, a fixing device for fixing the pump pipes needs to be constructed along the structural surface. However, in order to facilitate the installation of the pump pipes, the diameter of the internal placement cavity of the existing fixing device needs to be larger than the diameter of the pump pipes, which results in a certain gap between the pump pipes and the fixing device. Then, when pumping concrete, the pump pipes may shake or vibrate due to the change of internal pressure. Such shaking may not only cause loosening at the connection parts of the pump pipes, but also damage the pump pipes themselves, thus affecting the pumping efficiency and safety.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] In bridge design, there are many high pier structures. When the height of the pier column is not large, tower cranes or cranes are used to transport and place concrete for construction, but the efficiency is low, the equipment occupation time is long, and it is uneconomical; when the height of the pier column is relatively high, in order to improve the construction efficiency, the concrete pouring will adopt the pumping process. Not only is the construction efficiency high, but also the concrete is not easy to segregate, and the quality of the formed structure is good; considering comprehensively from aspects such as cost and applicability, the pumping process mostly uses ground pumps for construction. Therefore, during the construction process, the pump pipes need to be arranged along the pier column until the construction is completed. However, the fixing device for fixing the pump pipes cannot completely fit the pump pipes, and there is a certain gap between the fixing device and the pump pipes. When transporting concrete, the pump pipes may vibrate or shake under the action of the internal pressure, thereby affecting the stability of the pump pipe installation.

[0023] Embodiment 1

[0024] There is an assembly gap between the existing concrete pump pipe fixing device and the pump pipe, which is not conducive to improving the installation stability of the pump pipe. Referring to Figure 1-Figure 5 , this embodiment proposes a concrete pump pipe fixing device, which realizes the operation of fitting the pump pipe, reduces the movement gap of the pump pipe, and reduces the shaking amplitude of the pump pipe. It mainly consists of a fixing frame 1 and a placement cavity 2 for placing the pump pipe arranged in the fixing frame 1. The placement cavity 2 is in a "冂"-shaped structure, and a tightening component 4 for reducing the shaking amplitude of the pump pipe is arranged in the placement cavity 2. When installing the pump pipe, first install the pump pipe into the placement cavity 2, and then fit the pump pipe through the tightening component 4 to reduce the possible shaking amplitude.

[0025] In order to reduce the shaking amplitude of the pump pipe, through the setting of the tightening component 4 in this embodiment, the operation of fitting the pump pipe is realized, the movement gap of the pump pipe is reduced, and the shaking amplitude of the pump pipe is reduced. As shown in Figure 3As shown in the figure, the tightening component 4 includes a sealing member 41 rotatably mounted on one side of the fixed frame 1, and a clamping groove 43 for clamping one end of the sealing member 41 is provided on the fixed frame 1. An extrusion protrusion 42 for extruding the pump pipe is provided on one side of the sealing member 41. A first sliding cavity 45 and a second sliding cavity 46 communicating with each other are provided inside the fixed frame 1. The upper part of the first sliding cavity 45 communicates with the outside, and one side of the second sliding cavity 46 communicates with the placement cavity 2. A limiting and covering plate 47 that abuts against the pump pipe is slidably mounted in the first sliding cavity 45 and the second sliding cavity 46. A first top plate 48 and a second top plate 410 are provided in the first sliding cavity 45, and one side of the second top plate 410 abuts against one end of the limiting and covering plate 47. A tightening spring 49 is drivingly mounted between the first top plate 48 and the second top plate 410. The "冂"-shaped placement cavity 2 facilitates the placement of the pump pipe. After the placement is completed, the sealing member 41 is rotated into the clamping groove 43. Under the action of gravity, one end of the sealing member 41 will be firmly fixed in the clamping groove 43. During the rotation of the sealing member 41, the extrusion protrusion 42 provided thereon will extrude the pump pipe to move inward toward the placement cavity 2. During the movement of the pump pipe, it will abut against the limiting and covering plate 47 to move synchronously. The limiting and covering plate 47 will compress the tightening spring 49 through the second top plate 410. After the tightening spring 49 is compressed, it will generate a reverse acting force on the limiting and covering plate 47, making it closely fit on the surface of the pump pipe. Thus, the movement gap of the pump pipe is reduced. During the transportation of concrete, the change in air pressure inside the pump pipe will cause the pump pipe to vibrate. At this time, the tightening spring 49 is in a compressed state, and the reverse acting force it provides will resist the shaking of the pump pipe and reduce its movement amplitude. At the same time, if the vibration force is large, the tightening spring 49 can also slightly contract to absorb the vibration force, thereby alleviating the vibration impact on the pump pipe and improving the stability of the pump pipe fixation.

[0026] The cross-section of the second sliding cavity 46 is a parallelogram, and the lowest end faces the placement cavity 2. A partition plate 413 that can cover the communication part between the first sliding cavity 45 and the outside is fixedly installed on the upper part of the first top plate 48. The special setting of the cross-section of the second sliding cavity 46 can quickly discharge the rainwater and other impurities that enter the second sliding cavity 46 from the second sliding cavity 46, and the partition plate 413 can block the external impurities to prevent them from entering the first sliding cavity 45, thereby realizing the protection of the tightening spring 49 and reducing the influence of corrosion on its performance.

[0027] The contact surfaces of the extrusion protrusion 42 and the limiting and covering plate 47 with the pump pipe are both set as smooth curved surfaces. The setting of the contact surfaces of the extrusion protrusion 42 and the limiting and covering plate 47 with the pump pipe as smooth curved surfaces not only increases the contact area between them and the pump pipe, improves the fixation stability, but also reduces the extrusion damage caused to the pump pipe when extruding the pump pipe, reflecting the protection of the pump pipe.

[0028] The sealing member 41 is made of iron material, and an adsorption magnet 44 for adsorbing the sealing member 41 is provided at the bottom of the slot 43. The adsorption magnet 44 provided at the bottom of the slot 43 can adsorb the iron sealing member 41 so that it will not easily fall out of the slot 43, further improving the stability of the pump tube installation.

[0029] Embodiment 2

[0030] On the basis of the first embodiment, the technical solution proposed in the first embodiment is used to solve the disadvantage that there is an assembly gap between the existing concrete pump pipe fixing device and the pump pipe, which is not conducive to improving the pump pipe installation stability. However, the spring has a service life, and the elastic performance of the close spring 49 will decrease after multiple uses, so that the limit covering plate 47 cannot fit the pump pipe well.

[0031] Reference Figure 1-Figure 5 A guide groove 412 is provided on one side of the limiting covering plate 47, and a guide block 411 fixedly connected to the top plate 410 is slidably installed in the guide groove 412. The cross-sections of the guide block 411 and the guide groove 412 are both "T"-shaped. In this embodiment, the top plate 48, the top plate 410, the clamping spring 49 and the partition plate 413 can be replaced regularly through the arrangement of the guide groove 412 and the guide block 411, thereby ensuring the fitting performance of the limiting covering plate 47 to the pump tube. In addition, the arrangement of the "T"-shaped structure increases the contact area between the guide block 411 and the guide groove 412, thereby improving the stability of the movement of the limiting covering plate 47.

[0032] A connecting plate 3 is welded on one side of the fixing frame 1, and a plurality of mounting holes 5 are opened on the connecting plate 3, and mounting bolts 6 are connected to the inner threads of the mounting holes 5. When installing the existing pump pipe, an embedded part is generally set on the building first, and then the fixing device is welded on the embedded part. In this way, there are the disadvantages of troublesome installation and removal, low product reuse rate, and large removal loss. Moreover, after the fixing device is removed, it is difficult to repair the position of the embedded part on the building, and the repair quality is not easy to control. In this embodiment, during construction, a plurality of nuts matching the connecting bolts are embedded according to the positioning, and concrete pollution to the nuts should be avoided when pouring concrete. After the building template is climbed, the embedded nuts are cleared out on the building surface, and the mounting holes 5 set on the connecting plate 3 are aligned with the embedded nuts and fixed firmly with the mounting bolts 6. This installation method is convenient to install and can be reused. Moreover, the embedded parts on the building have little influence on the structure, and there are only a few embedded holes of the size of nuts. It is convenient to seal them with cement slurry or fine stone concrete later, and the repair quality is guaranteed.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
