Detailed implementation manners
[0031] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present utility model will be described below with reference to the drawings.
[0032] As Figures 1 to 6 shown, the present utility model discloses a buffer-type concrete pump pipe fixing device, which is applied to the concrete pump pipe 5. The buffer-type concrete pump pipe fixing device includes a base 1, a buffer device 2 and a clamping device 3. Among them, the base 1 is arranged on the concrete layer 4, and the concrete layer 4 can be a floor slab. The base 1 has the function of bearing the weight of the pump pipe 5 and the vibration generated during work, avoiding direct impact on the concrete layer 4. The material of the base 1 can be metal or carbon fiber, etc. A reserved opening 41 is provided on the concrete layer 4, and the base 1 is located on both sides of the reserved opening 41. The pump pipe 5 is accommodated in the reserved opening 41. It should be noted that the shape of the reserved opening 41 can be a circular structure, a square structure, etc., as long as it can accommodate the pump pipe 5. In this regard, there are no excessive restrictions in this application.
[0033] Continue to refer to Figures 1 to 4, the buffer device 2 is located above the base 1. The buffer device 2 includes a buffer spring 21. The buffer spring 21 has the function of absorbing vibration and impact force, preventing the concrete layer 4 and the surrounding structures from being directly impacted and damaged, thereby ensuring the normal operation of the pump pipe 5. In one example, as Figure 1 shown, one end of the buffer spring 21 is fixedly connected to the base 1, and the other end of the buffer spring 21 is connected to the pump pipe 5. During the operation of the concrete pump pipe, since the concrete pump can generate vibration loads, the buffer spring 21 is loaded and undergoes large elastic deformation, which can effectively absorb the impact force. After unloading, the deformation of the buffer spring 21 disappears and returns to its original state, thereby effectively reducing the impact force of the pump pipe 5 on the concrete layer 4 and the surrounding structures, and further ensuring the integrity of the structure and the normal operation of the work.
[0034] The clamping device 3 is connected to the buffer device 2 and the pump pipe 5. The clamping device 3 is used to clamp the pump pipe 5 to ensure that the position of the pump pipe 5 is not easily offset during operation. The pump pipe 5 is connected to the buffer spring 21 through the clamp 31. The clamping device 3 includes a clamp 31. One end of the clamp 31 clamps the pump pipe 5, and the other end of the clamp 31 is fixedly connected to the buffer spring 21. When the pump pipe is working, the clamp 31 can effectively limit the position of the pump pipe 5, preventing it from shifting during vibration and affecting the normal operation and quality of subsequent work.
[0035] Among them, the pump pipe 5 is perpendicular to the concrete layer 4, which ensures the effective transportation of the pump pipe 5, reduces friction and resistance, and avoids the accumulation of concrete slurry, thereby improving the transportation efficiency of the concrete pump. Along the radial direction of the pump pipe 5, the inner diameter of the clamp 31 and the outer diameter of the pump pipe 5 can be adaptively set and adjusted according to requirements, so that the clamp 31 can match different pump pipes 5, thereby improving the stability and flexibility of the pump pipe 5. As Figure 5 and Figure 6 shown, for example, when the clamp 31 is in the first preset state, the inner diameter of the clamp 31 is the same as the outer diameter of the pump pipe 5. The clamp 31 can tightly wrap the pump pipe 5 so that the pump pipe 5 is firmly fixed and not easily displaced, improving the stability of the device. At the same time, it can also effectively prevent the pump pipe 5 from loosening due to vibration or pumping pressure, reducing potential safety hazards. When the clamp 31 is in the second preset state, the inner diameter of the clamp 31 is larger than the outer diameter of the pump pipe 5. The clamp 31 can be flexibly connected and adjusted, enabling the clamp 31 to quickly disassemble or reinstall the pump pipe 5. When it is necessary to replace the pump pipe 5 or adjust its position, it is convenient for the operator to make corresponding adjustments and maintenance, thereby improving work efficiency and reducing time waste caused by inconvenient adjustment.
[0036] The buffer spring of the buffer device cooperates with the fixture of the clamping device to ensure that the pump pipe is firmly installed on the concrete layer. When the concrete pump is working, the vertical vibration load generated is relieved of the impact force and shock-absorbed through the buffer device, so as to reduce the extrusion collision and vibration on the concrete layer and the surrounding structures. And the fixture can be adjusted to different preset states according to the needs to match different types of pump pipes, so as to ensure the fixity and usability of the pump pipe, and then ensure the normal operation of the device. The device is simple to manufacture, low in cost, and effectively enhances the strength and support force of the structure, thus ensuring the use reliability and stable safety of the device.
[0037] In some embodiments, as Figures 1 to 6 shown, the buffer device 2 further includes a plurality of telescopic rods 22. The plurality of telescopic rods 22 are arranged on the base 1 and connected to the fixture 31. The plurality of telescopic rods 22 can be telescopically extended and retracted in the axial direction of the pump pipe 5. When pumping concrete, due to the change of the fluid pressure in the pump pipe 5, the pump pipe 5 will generate a certain displacement and vibration. When the pump pipe 5 moves upward under the action of pressure or other external forces, the telescopic rods 22 can automatically extend to maintain the fastening state of the fixture 31, so as to firmly fix the pump pipe 5 without increasing additional fixing force. At the same time, it also has the functions of buffering and shock absorption. The telescopic rods 22 can consume part of the energy when the pump pipe 5 is subjected to sudden pressure changes, so that the telescopic rods 22 and the buffer spring 21 cooperate with each other for double protection, thereby reducing the direct impact on the fixture 31 and the pump pipe 5. Furthermore, it reduces the risk of structural damage such as pump pipes or concrete layers caused by vibration and extends the service life of the entire pumping system. In an example (not shown in the drawings), the telescopic rod also has a locking device. When the pump pipe needs to be fixed in the working state, the locking device can effectively lock the position of the telescopic rod. When it is necessary to adjust or replace the pump pipe, the operator can easily release the lock and operate conveniently.
[0038] In some embodiments, as Figure 1 and Figure 5 shown, the fixture 31 is a clamp, and the clamp is composed of an inner ring and an outer ring. The inner ring is in close contact with the pump pipe 5, and the outer ring is set in an adjustable form to realize clamping and loosening of the pump pipe 5, which can ensure that the fixture can be evenly distributed around the pump pipe 5 and avoid deformation or damage of the pump pipe 5 caused by excessive local force. The connection end 311 of the clamp is welded to the buffer spring 21, and the working end 312 of the clamp is detachably connected to the pump pipe 5, so that the clamp can clamp or loosen the pump pipe 5, thereby being able to clamp and fix and disassemble and repair the pump pipe 5. When the pump pipe 5 conveys concrete, the pressure and vibration borne by the pump pipe 5 will be transmitted from the fixture 31 to the buffer spring 21, and the buffer spring 21 can absorb part of the energy through its elastic characteristics, thereby reducing the impact on the connection point between the fixture 31 and the pump pipe 5 and reducing the potential damage risk.
[0039] In an example, continue to refer to Figures 1 to 6, the surface of the working end 312 of the clamp in contact with the pump pipe 5 is a rough surface. When the clamp clamps the pump pipe 5, it can increase the friction force of the contact surface, thereby avoiding sliding or displacement between the clamp and the pump pipe 5. In another example, a gasket is provided on the side wall of the working end 312 of the clamp in contact with the pump pipe 5. The gasket can be made of rubber. The rubber gasket can further enhance the clamping effect, and the rubber gasket has good elasticity and deformation ability. During the clamping process, it can provide a more uniform contact pressure according to the shape of the pump pipe 5, so that the clamp tightly wraps the pump pipe 5. At the same time, the rubber gasket also has sealing performance to prevent slurry leakage at the connection between the pump pipe 5 and the clamp.
[0040] Among them, as Figure 5 and Figure 6 shown, the clamp includes a left clamp 32 and a right clamp 33. The left clamp 32 and the right clamp 33 are arranged oppositely and both are in a Y-shaped structure so as to be sleeved on the pump pipe 5. In the assembled state, the left clamp 32 and the right clamp 33 adaptively adjust the distance between them according to the outer diameter of the pump pipe 5 to ensure that the pump pipe 5 can be tightly fixed.
[0041] In some embodiments, as Figure 1 shown, the fixing device further includes a buffer plate 7. The buffer plate 7 is used to buffer the load force generated by the pump pipe 5. The buffer plate 7 is located between the base 1 and the concrete layer 4. The buffer plate 7 is in a square structure. Expansion screws 8 are used to fix the buffer plate 7 and the base 1 to the concrete layer 4 to reduce the impact force of the pump pipe 5 on the concrete layer 4, thereby ensuring the integrity and safety of the concrete layer 4 and the surrounding structures.
[0042] In some embodiments, as Figures 1 to 6 shown, the buffer plate 7 is a rubber plate. The rubber plate can absorb the impact force better, and in the thickness direction of the concrete layer 4 (such as the z direction shown in Figure 1 ), the thickness of the buffer plate 7 is greater than the thickness of the base 1. In one example, the base 1 is a steel plate, and the size of the steel plate is 400mm * 100mm * 3mm, and the size of the rubber plate is 400mm * 100mm * 20mm. The steel plate has strength and can withstand the pressure of the expansion screws 8, avoiding cracks during the fixation of the steel plate and the rubber plate, resulting in insecure fixation. The steel plate and the rubber plate are used in matching to effectively reduce the impact force on the concrete layer 4, and at the same time can support the buffer device, thereby ensuring the normal operation of the work.
[0043] In some embodiments, as Figure 3As shown, the radial length of the pump pipe 5 is less than the radial length of the reserved opening 41 to ensure that the pump pipe 5 extends into the reserved opening 41. At the same time, there is a distance between the outer diameter of the pump pipe 5 and the concrete layer 4. During the operation of the concrete pump pipe, since the pump pipe 5 will vibrate and is likely to collide with the concrete layer 4, the radial length of the pump pipe 5 is set to be less than the radial length of the reserved opening 41 to avoid the pump pipe 5 touching the concrete layer 4 and to ensure the subsequent quality.
[0044] The working principle of a buffer-type concrete layer pump pipe fixing device provided by the present utility model is as follows:
[0045] As Figures 1 to 6 shown, first, a buffer plate 7 and a base 1 are sequentially placed on the edge of the concrete layer 4 close to the reserved opening 41 and fixed with expansion screws 8 to prevent deviation during operation.
[0046] After that, one end of the pump pipe 5 is placed at the reserved opening 41 and fixed with a clamp 31 on the clamping device 3. A buffer spring 21 of the buffer device 2 is welded between the clamp 31 and the base 1, so that one end of the buffer spring 21 is welded to the clamp 31 and the other end of the buffer spring 21 is welded to the base 1.
[0047] Finally, a gasket 6 is placed between the clamp 31 and the pump pipe 5 to increase the friction force, prevent the clamp 31 from slipping, adjust the clamp 31 to fit the size of the pump pipe 5 and tightly fix the pump pipe 5. At the same time, bolts are used for fixation to prevent the clamp 31 from loosening, thus completing the fixation of the concrete pump pipe.
[0048] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the scope of protection of the claims of the present utility model.
