Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pipe erection structures, and in particular to a concrete pump pipe erection structure. Background Art
[0002] Pumping concrete is the use of concrete pumps or pump trucks to transport and pour concrete mixtures along delivery pipes. It is an effective way to transport concrete mixtures. It is fast and labor-saving, and is especially suitable for the transportation and pouring of large-volume concrete and high-rise building concrete. In the above process, pump pipes are needed as the medium for concrete transportation. Pump pipes are the abbreviation of concrete delivery pump pipelines. Because concrete is referred to as concrete, it is often called concrete pump pipes. It is easy to understand that pump pipes are a new type of construction engineering accessories that appeared with the emergence of concrete delivery pumps. Its emergence has greatly improved the efficiency of construction, and changed the previous operation method of using manual labor or cranes to quickly transport concrete to the place where it needs to be poured. When using concrete pump pipes, it is necessary to set up a structure to support and fix them to prevent them from shaking under the impact of concrete and deviating from the original laying track, or causing damage to the pipeline.
[0003] The existing concrete pump pipe installation structure usually clamps and fixes the pipe by means of upper and lower fixing rings to prevent it from sliding or slipping, thereby ensuring the normal operation of concrete pumping. However, the spacing between the upper and lower fixing rings is usually preset, and it is difficult to effectively clamp and fix pipes of different diameters within a certain range, and its versatility is poor. At the same time, the upper and lower fixing rings are usually fixed with a combination of bolts and nuts, but the bolts and nuts are easy to lose during the disassembly process, and they need to be re-equipped when they are used again, which is inconvenient. Therefore, a concrete pump pipe installation structure is proposed to address the above problems. Utility Model Content
[0004] In response to the shortcomings of the prior art, the present application provides a concrete pump pipe installation structure, which overcomes the shortcomings of the prior art and aims to solve the problem that the pump pipe installation structure is difficult to effectively clamp and fix pipes of different diameters within a certain range and the fixing bolts and nuts are easily lost during the disassembly process.
[0005] To achieve the above objectives, this application provides the following technical solutions:
[0006] The concrete pump pipe erection structure comprises an upper fixed semi-ring and a lower fixed semi-ring, and is characterized in that the upper fixed semi-ring and the lower fixed semi-ring are fixedly connected by anti-drop fixing bolts, a through sliding groove is opened in the middle of the upper fixed semi-ring, a fixed size adjustable mechanism is arranged in the sliding groove, the fixed size adjustable mechanism comprises an in-groove mounting block fixedly arranged in the upper sliding groove of the upper fixed semi-ring, an adjusting screw is rotatably connected to the in-groove mounting block, a threaded sliding block is arranged on the outer sleeve of the adjusting screw, side connecting curved plates are fixedly arranged on both sides of the sliding block, a vertical sliding connecting plate is fixedly connected to the end of the side connecting curved plate, and an extrusion curved plate is fixedly connected between the bottoms of the vertical sliding connecting plates.
[0007] By adopting the above technical solution, after the upper fixed half ring and the lower fixed half ring are assembled and sleeved outside the pipeline to be erected, the adjusting screw is turned to rotate. Under the meshing action of the thread, the sliding block will slide up and down, thereby driving the extruded curved plate fixedly connected to the vertical sliding connecting plate to move up and down, thereby changing the spacing between the extruded curved plate and the upper fixed half ring, thereby adjusting the clamping size, and making the overall structure able to firmly and effectively fix pipelines of different diameters within a certain range, and has strong versatility.
[0008] As a preferred technical solution of the present application, the widths of the sliding block, the side connecting curved plate, the vertical sliding connecting plate and the extruded curved plate are numerically equal to the width of the sliding groove.
[0009] By adopting the above technical solution, it can be ensured that the above structure slides up and down smoothly in the sliding groove without shaking, thereby ensuring the firmness of the fixation.
[0010] As a preferred technical solution of the present application, the lower end surface of the extruded curved plate can fit tightly with the upper end surface of the lower fixed half ring.
[0011] By adopting the above technical solution, the extruded curved plate can be perfectly fitted with the lower fixed half ring without lifting, and the installation of the lower fixed half ring will not be hindered.
[0012] As a preferred technical solution of the present application, threaded connection tubes are embedded in the plates on both sides of the lower fixed half ring, and a threaded structure is provided on the inner wall of the threaded connection tubes.
[0013] By adopting the above technical solution, the embedded threaded connection cylinder is used to replace the movable nut structure, thereby avoiding the possibility of the nut being lost during the disassembly process.
[0014] As a preferred technical solution of the present application, the anti-drop fixing bolt includes a bolt body, the thread size of the bolt body matches the thread size on the inner wall of the threaded connection tube, a pressure plate is fixedly arranged on the outside of the upper bolt rod of the bolt body, a ring is provided on the outer sleeve of the bolt rod between the nut of the bolt body and the pressure plate, a connecting block is fixedly arranged on the side of the upper fixed half ring, a connecting belt is connected to the connecting block, and the end of the connecting belt away from the connecting block is fixedly connected to the ring.
[0015] By adopting the above technical solution, after the bolt body is unscrewed to separate its bottom from the threaded connection tube, the height to which the bolt body can be further lifted will be limited due to the presence of the connecting belt, making it impossible for it to completely detach from the upper fixing half ring, thereby effectively preventing the bolt body from being lost due to excessive lifting and detachment from the upper fixing half ring.
[0016] As a preferred technical solution of the present application, a supporting fixing structure is fixedly provided on the lower end surface of the lower fixed semi-ring, and the supporting fixing structure includes a main support rod fixedly connected to the lower end surface of the lower fixed semi-ring, and a bottom plate is fixedly connected to the bottom of the main support rod.
[0017] By adopting the above technical solution, the whole structure can be fixed on the building surface by the bottom plate to achieve fixed installation of the whole erection structure.
[0018] As a preferred technical solution of the present application, a transverse connecting rod is fixedly connected between the main supporting rods, and a secondary reinforcing rod is fixedly connected between the transverse connecting rod and the lower end surface of the bottom plate.
[0019] By adopting the above technical solution, the bearing capacity and rigidity of the entire supporting fixed structure can be enhanced, so that it can still remain stable when bearing the dynamic load caused by the flow of concrete.
[0020] The beneficial effects of the present application are as follows: after the upper fixed half ring and the lower fixed half ring are assembled and sleeved outside the pipe to be erected, the adjusting screw is turned to rotate, and the sliding block will slide up and down under the meshing action of the thread, thereby driving the extrusion curved plate fixedly connected to the vertical sliding connecting plate to move up and down, thereby changing the spacing between the extrusion curved plate and the upper fixed half ring, thereby adjusting the clamping size, and making the overall structure able to firmly and effectively fix pipes of different diameters within a certain range, with strong versatility. At the same time, the bolt body will be restricted by the connecting belt, so that it cannot be completely separated from the upper fixed half ring, and thus it will not be lost during the disassembly process.

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0026] Reference Figure 1 The concrete pump pipe erection structure comprises an upper fixed half ring 1 and a lower fixed half ring 2, and is characterized in that the upper fixed half ring 1 and the lower fixed half ring 2 are fixedly connected by an anti-drop fixing bolt 3, a through sliding groove 11 is opened in the middle of the upper fixed half ring 1, and a fixed size adjustable mechanism 4 is arranged in the sliding groove 11. After the upper fixed half ring 1 and the lower fixed half ring 2 are assembled and sleeved outside the pipeline to be erected, the spacing between the supporting structures can be changed by the fixed size adjustable mechanism 4, so as to adjust the clamping size, so that the overall structure can firmly and effectively fix pipelines of different diameters within a certain range, and has strong versatility.
[0027] Reference Figure 2 The fixed size adjustable mechanism 4 includes a groove mounting block 41 fixedly arranged in the upper sliding groove 11 of the upper fixed semi-ring 1, and an adjusting screw 42 is rotatably connected to the groove mounting block 41. The adjusting screw 42 is provided with a threaded sliding block 43 on the outer sleeve, and side connecting curved plates 44 are fixedly arranged on both sides of the sliding block 43. The end of the side connecting curved plate 44 is fixedly connected to a vertical sliding connecting plate 45, and an extrusion curved plate 46 is fixedly connected between the bottoms of the vertical sliding connecting plates 45. By adopting the above technical scheme, the adjusting screw 42 is turned to rotate, and the sliding block 43 will slide up and down under the meshing action of the thread, thereby driving the extrusion curved plate 46 fixedly connected to the vertical sliding connecting plate 45 to move up and down, thereby changing the distance between the extrusion curved plate 46 and the upper fixed semi-ring 1, so as to adjust the clamping size, so that the overall structure can play a firm and effective fixing role for pipes of different diameters within a certain range, and has strong versatility.
[0028] Reference Figure 2 The widths of the sliding block 43, the side connecting curved plate 44, the vertical sliding connecting plate 45 and the extrusion curved plate 46 are numerically equal to the width of the sliding groove 11. The above-mentioned structural form can ensure that the above-mentioned structure slides up and down smoothly in the sliding groove 11 without shaking, so as to ensure the firmness of the fixation. The lower end surface of the extrusion curved plate 46 can fit tightly with the upper end surface of the lower fixed half ring 2. This structural form can make it fit perfectly with the lower fixed half ring 2 without lifting the extrusion curved plate 46, and will not hinder the installation of the lower fixed half ring 2.
[0029] Reference Figure 3 , threaded connection tubes 21 are embedded in the plates on both sides of the lower fixed half ring 2, and a threaded structure is provided on the inner wall of the threaded connection tube 21. By adopting the above technical solution, the embedded threaded connection tube 21 is used to replace the movable nut structure, thereby avoiding the possibility of the nut being lost during the disassembly process.
[0030] Reference Figure 3 The anti-fall fixing bolt 3 includes a bolt body 31, the thread size of the bolt body 31 matches the thread size on the inner wall of the threaded connecting tube 21, and a pressing plate 32 is fixedly arranged on the outer surface of the bolt rod of the upper part of the bolt body 31, and a collar 33 is provided on the bolt rod outer sleeve between the nut of the bolt body 31 and the pressing plate 32, and a connecting block 34 is fixedly arranged on the side of the upper fixing half ring 1, and a connecting belt 35 is connected to the connecting block 34, and the end of the connecting belt 35 away from the connecting block 34 is fixedly connected to the collar 33. By adopting the above technical scheme, after the bolt body 31 is unscrewed to separate its bottom from the threaded connecting tube 21, due to the existence of the connecting belt 35, the height of the bolt body 31 that continues to be lifted will be limited, so that it cannot be completely separated from the upper fixing half ring 1, thereby effectively preventing the bolt body 31 from being easily lost due to excessive lifting and separation from the upper fixing half ring 1.
[0031] Reference Figure 1 A supporting and fixing structure 5 is fixedly provided on the lower end surface of the lower fixed semi-ring 2, and the supporting and fixing structure 5 includes a main support rod 51 fixedly connected to the lower end surface of the lower fixed semi-ring 2, and a bottom plate 52 is fixedly connected to the bottom of the main support rod 51. The bottom plate 52 can be used to fix the entire structure on the building surface to achieve fixed installation of the entire erection structure. In addition, a transverse connecting rod 53 is fixedly connected between the main support rods 51, and a secondary reinforcing rod 54 is fixedly connected to the transverse connecting rod 53 and the lower end surface of the bottom plate 52. The above structural form can enhance the overall bearing capacity and rigidity of the supporting and fixing structure 5, so that it can still remain stable when subjected to the dynamic load brought by the flow of concrete.
[0032] Working principle: fix the whole structure at the designated position on the building surface through the bottom plate 52, remove the upper fixing half ring 1, make the pumping pipe contact with the extrusion curved plate 46 at the bottom of the lower fixing half ring 2, and then fix the upper fixing half ring 1 and the lower fixing half ring 2 through the anti-drop fixing bolts 3. As the anti-drop fixing bolts 3 are tightened continuously, the holding force between the upper fixing half ring 1 and the lower fixing half ring 2 is continuously increased, thereby achieving the holding and fixing of the pipeline;
[0033] When the pipe diameter is smaller than the clamping size between the upper fixed half ring 1 and the lower fixed half ring 2, the adjusting screw 42 is turned to rotate, and the sliding block 43 will slide up and down under the meshing action of the thread, thereby driving the extrusion curved plate 46 fixedly connected to the vertical sliding connecting plate 45 to move up and down, thereby changing the distance between the extrusion curved plate 46 and the upper fixed half ring 1, so as to adjust the clamping size, and thus the overall structure can play a firm and effective fixing role for pipes of different diameters within a certain range, and has strong versatility;
[0034] When removing the upper fixing half ring 1, unscrew the bolt body 31 to separate its bottom from the threaded connection tube 21. Due to the presence of the connecting belt 35, the height to which the bolt body 31 can be further lifted will be limited, making it impossible for it to completely detach from the upper fixing half ring 1, thereby effectively preventing the bolt body 31 from being lost due to excessive lifting and detachment from the upper fixing half ring 1.
[0035] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. Although the present application is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
