Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a direction-changing pipe supporting device for a concrete pump pipe. Background Art

[0002] During the construction of concrete structures, pouring concrete is a key step in the entire construction process. Concrete pump pipes need to be laid out at the construction site to meet the needs of concrete pouring. The continuous and stable transportation of concrete in the pipeline is particularly important for high-rise and super-high-rise concrete construction. During the pumping process, the position of the change-over pipe (elbow or elbow) from the horizontal section of the pump pipe to the vertical section is very likely to move, causing the interruption of concrete transportation in the entire pipeline. The reason is that the concrete in the pumping pipe generates a large impact load and reciprocating load, which has an adverse effect on the change-over position, such as damage and failure of the pump pipe and related accessories. At the same time, under the action of reciprocating impact loads, the pump pipe shakes too much, the pipe is damaged, and even bursts, causing many safety hazards.

[0003] For the installation of directional changeover pipes, which transition from horizontal to vertical sections, the pipes are typically embedded in concrete piers or pre-installed with steel plate inserts within the piers, then secured to the inserts. This conventional approach to directional changeover pipes has numerous drawbacks: The rigid, constrained connection is not robust against reciprocating impact loads; on-site replacement and maintenance are difficult, requiring the removal of the concrete piers; and the subsequent removal of the concrete piers increases material and labor costs, while also increasing solid waste emissions.

[0004] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0005] In order to overcome the defects of the existing technology, a deflection pipe support device for a concrete pump pipe is provided to solve the problem that the conventional installation method of the deflection pipe of the concrete pump pipe cannot withstand the reciprocating impact load of the pumped concrete and the subsequent maintenance is difficult.

[0006] To achieve the above-mentioned purpose, a deflection pipe support device for a concrete pump pipe is provided, comprising:

[0007] The support frame includes two guide rails arranged opposite to each other and a plurality of bearing members, wherein the guide rails include a horizontal section fixed to the ground and a vertical section connected to the horizontal section, and both ends of at least one of the bearing members are slidably mounted on the horizontal sections of the two guide rails, and both ends of at least one of the bearing members are slidably mounted on the vertical sections of the two guide rails;

[0008] The energy dissipation support includes a base plate for mounting the direction-changing tube and a guide rod, wherein the base plate is elastically mounted on the bearing member and has a through hole formed therein. The guide rod is vertically mounted on the bearing member, and the upper end of the guide rod is slidably mounted in the through hole.

[0009] Damping support rods are hingedly connected between the base plate and the guide rail, and between the vertical section and the ground.

[0010] Furthermore, the horizontal section and the vertical section are respectively formed with sliding grooves, and the opposite ends of the bearing member are respectively slidably arranged in the sliding grooves at opposite positions on the two guide rails.

[0011] Furthermore, sliders are formed at both ends of the bearing member, and the sliders are slidably arranged in the sliding grooves. The notches of the sliding grooves are opposite to form anti-slip flanges for preventing the sliders from slipping.

[0012] Furthermore, the damping support rod is arranged at an angle to the concrete pumping direction.

[0013] Furthermore, the damping support rods on opposite sides of the base plate are respectively arranged obliquely toward the rear of the concrete pumping direction.

[0014] Furthermore, the damping support rod is obliquely hingedly connected between the opposite sides of the vertical sections of the two guide rails and the ground, and the damping support rod is arranged coplanar with the vertical section.

[0015] Furthermore, the substrate is elastically mounted on the supporting member via a coil spring.

[0016] Furthermore, the coil spring is movably sleeved on the guide rod.

[0017] Furthermore, a limiting member is detachably mounted on the upper end of the guide rod, and the limiting member abuts against a side of the base plate away from the supporting member.

[0018] Furthermore, the base plate is fixedly connected to the direction-changing tube via a tube clamp.

[0019] The beneficial effect of the present invention is that the support device for the change-direction pipe of the concrete pump pipe of the present invention has a support frame that satisfies the basic reinforcement conditions of the change-direction pipe position while providing an energy dissipation support to consume the reciprocating impact load generated during the concrete pumping process. The energy dissipation support meets the dissipation of a large number of adverse loads through the obliquely arranged damping support rod and the elastic energy dissipation pad on the inner side of the pipe clamp, reduces the vibration amplitude of the pump pipe during pumping, reduces the impact of adverse loads, protects the weak position of the pump pipe change-direction pipe, and ensures the long-term stable operation of the pump pipe and accessories. The support device for the change-direction pipe of the concrete pump pipe of the present invention has high flexibility, adaptability, and operability, and can be specifically set according to different working conditions, overcoming the defects of the concrete pier having more processes, being unable to turn over, and generating more solid waste.

[0026] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] Reference Figures 1 to 5 As shown, the present invention provides a deflection pipe support device for a concrete pump pipe, comprising: a support frame 1, an energy dissipation support 2 and a damping support rod 3.

[0029] The support frame 1 includes two guide rails and a plurality of bearing members 12. The two guide rails are arranged opposite to each other.

[0030] See Figure 1 and Figure 2 The guide rail includes a horizontal section 111 and a vertical section 112. The horizontal section 111 is fixed to the ground. The vertical section 112 is connected to the horizontal section 111. The vertical section is set at an angle to the horizontal section. Figure 1 The deflector pipe 4 of the concrete pump pipe includes a horizontal pipe section 41 and a vertical pipe section 42. The vertical pipe section 42 is arranged in the vertical direction. The vertical pipe section 42 is connected to the horizontal pipe section 41 through an arc-shaped transition bend. In this embodiment, the shape of the guide rail is adapted to the shape of the deflector pipe and is L-shaped.

[0031] The horizontal sections of the two guide rails are provided with bearing members, and the vertical sections of the two guide rails are also provided with bearing members. In this embodiment, the bearing members are plate-shaped.

[0032] Two ends of at least one bearing member 12 among the plurality of bearing members are slidably mounted on the horizontal sections 111 of the two guide rails; two ends of at least one bearing member 12 among the plurality of bearing members are slidably mounted on the vertical sections 112 of the two guide rails.

[0033] In this embodiment, a bearing member is movably connected between the horizontal sections of the two guide rails, and a bearing member is movably connected between the vertical sections of the two guide rails.

[0034] Each support member is mounted with an energy dissipation support. The energy dissipation support 2 comprises a base plate 21 and a guide rod 22. The base plate 21 is used to mount the diverter tube 4. Specifically, the base plate on the support member located on the horizontal section of the guide rail is used to mount the horizontal section of the diverter tube; the base plate on the support member located on the vertical section of the guide rail is used to mount the vertical section of the diverter tube.

[0035] The base plate 21 is elastically mounted on the carrier 12. A through hole is formed in the base plate 21. The guide rod 22 is vertically mounted on the carrier 12. The upper end of the guide rod 22 is slidably mounted in the through hole.

[0036] See Figure 1 and Figure 3 A damping support rod 3 is hingedly connected between the base plate 21 and the guide rail. In addition, a damping support rod 3 is hingedly connected between the vertical section 112 and the ground.

[0037] As a preferred embodiment, see Figure 2 As shown, the horizontal section 111 and the vertical section 112 of the guide rail are respectively formed with sliding grooves. The opposite ends of the carrier 12 are respectively slidably arranged in the opposite sliding grooves on the two guide rails.

[0038] In this embodiment, a slider 121 is formed at each end of the carrier 12. The slider 121 is slidably disposed in a chute. An anti-slip flange is formed opposite the notch of the chute. The anti-slip flange is used to prevent the slider 121 from slipping.

[0039] In this embodiment, the two opposite sides of each energy dissipation support are connected to the horizontal section or vertical section of the guide rail through a damping support rod. Figure 3 The solid black arrow in the figure shows an angled arrangement.

[0040] The damping support rods 3 on opposite sides of the base plate 21 are respectively arranged obliquely to the rear of the concrete pumping direction. Figure 2 The damping support rods 3 on the opposite sides of the base plate on the vertical section of the guide rail are respectively arranged obliquely to the rear of the concrete pumping direction.

[0041] The damping support rod 3 is hingedly connected between the opposite sides of the vertical sections 112 of the two guide rails and the ground. The damping support rod 3 and the vertical section 112 are arranged coplanarly.

[0042] The horizontal section, the vertical section and the base plate of the guide rail are respectively connected with vertically arranged ear plates. Both ends of the damping support rod are respectively hinged to the ear plates through hinge shafts.

[0043] Continue reading Figure 4 and Figure 5 The base plate 21 is elastically mounted on the carrier 12 via a coil spring 23 . The coil spring 23 is movably sleeved on the guide rod 22 .

[0044] A limiting member is detachably mounted on the upper end of the guide rod 22 , and the limiting member abuts against a side of the base plate 21 away from the supporting member 12 .

[0045] In this embodiment, the limiting member is provided with a threaded hole, and an end of the guide rod away from the supporting member is formed with an external thread, and the threaded hole of the limiting member is screwed into the external thread of the end of the guide rod.

[0046] The base plate 21 is fixedly connected to the change-direction pipe 4 through a pipe clamp 24. The contact surface between the pipe clamp and the change-direction pipe is paved with an elastic energy dissipation pad. The elastic energy dissipation pad is a rubber pad.

[0047] The deflection pipe support device for concrete pump pipes of the present invention adopts a support frame made of section steel. The guide rail is an I-steel. An oblique reinforcement strut is connected between the horizontal section and the vertical section of the guide rail. While meeting the basic reinforcement conditions of the deflection pipe position, the support frame is provided with an energy dissipation support to consume the reciprocating impact load generated during the concrete pumping process. The energy dissipation support meets the dissipation of a large number of adverse loads through the obliquely arranged damping support rods and the elastic energy dissipation pads on the inner side of the pipe clamp, reduces the vibration amplitude of the pump pipe during the pumping process, reduces the impact of adverse loads, protects the weak position of the pump pipe deflection pipe, and ensures the long-term stable operation of the pump pipe and accessories. The deflection pipe support device for concrete pump pipes of the present invention has high flexibility, adaptability, and operability, and can be specifically set according to different working conditions, overcoming the defects of the concrete pier having many processes, being unable to turn around, and generating a lot of solid waste. It improves the safety and reliability of the position of the pump pipe deflection pipe and ensures stable concrete pumping.

[0048] The support frame of the deflection pipe support device for the concrete pump pipe of the present invention is composed of two triangular steel frames, and the ends of the horizontal sections of the two guide rails and the ends of the vertical sections of the two guide rails are connected by connecting beams to form a stable system. The support frame determines the diameter and specifications of the pump pipe by calculating the pressure, impact load and other parameters during concrete pumping, and further determines the size specifications and materials of the support frame. The support frame is processed to form a stable support skeleton system. Compared with the traditional concrete pier form, the steel structure assembly frame has better adaptability on site, and the design parameters can be adjusted according to different working conditions to meet the conditions for pump pipe support and tightening. After the construction is completed, it can be used for other projects, while avoiding the construction and removal of concrete piers.

[0049] Two energy dissipation supports are installed on the guide rails through damping support rods. While supporting and restraining the pump pipe, they cooperate with the damping support rods to reduce pipeline vibration. The damping support rods overcome the reciprocating action of the concrete pouring process, avoid excessive impact of the rigid connection and stabilize the device.

[0050] An elastic energy dissipation pad is laid at the connection between the pump pipe and the pipe clamp, and the elastic energy dissipation pad is arranged in a circle along the circumferential direction of the pump pipe.

[0051] During the pumping process, the pump truck uses a pressure device to pump concrete to a higher or farther position, and at the same time generates a large reciprocating impact load. This type of load is extremely detrimental to the pump pipe, especially in the horizontal

[0052] The position of the changing pipe of the vertical section has the greatest impact, so horizontal and vertical damping support rods are set to connect the base plate of the changing pipe to reduce the effect of the reciprocating impact load on the pump pipe. Auxiliary damping support rods are set on the opposite sides of the support frame to enhance the stability of the changing pipe support device for the concrete pump pipe of the present invention, assist in consuming the reciprocating impact load, and the damping support rod can quickly dissipate the reciprocating impact load, reduce the vibration amplitude of the pump pipe, and reduce the impact of the reciprocating impact load on the pump pipe.

[0053] The bearing members arranged on the horizontal and vertical sections of the guide rail serve as the horizontal and vertical fulcrums of this section of the pump pipe. At the same time, the base plate adopts the energy dissipation coil spring support of the guide rod to realize the effective constraint of the pump pipe under the action of reciprocating load. On the other hand, the horizontal and vertical pump pipe constraint positions can be adjusted through the bearing members to improve the adaptability. At the same time, an overall energy dissipation system is formed with the horizontal and vertical damping support rods to jointly resist the reciprocating impact load when pumping concrete, and most of the

[0054] The energy of adverse loads is converted and dissipated, thereby protecting the horizontal to vertical change-of-direction pipe section, ensuring stable and continuous delivery of 5-meter concrete, and the safety and effectiveness of various components of the pump pipe.

[0055] The deflection pipe support device for a concrete pump pipe of the present invention ensures that the horizontal pipe section of the deflection pipe of the pump pipe is effectively constrained when the deflection pipe is rotated to the vertical pipe section. A combination of a highly flexible steel structure and energy dissipation components is adopted to overcome the impact problem and ensure that the support and fastening are effective for a long time.

[0056] The whole can be designed and processed according to the actual situation on site, with easy assembly and disassembly, high adaptability and operability on site. At the same time, when the pipeline needs to be repaired and replaced and the deflection pipe section needs to be removed, only the section of the pipe needs to be removed.

[0057] That is, it avoids the difficulty of replacing the traditional pre-buried concrete piers and reduces material and labor costs. At the same time, the support and fastening device has the conditions for turnover use, avoiding the labor and mechanical costs of breaking the concrete piers and the generation of solid waste, and meets the green and low-carbon requirements.

[0058] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention herein is not limited to the technical solutions formed by the specific combination of the aforementioned technical features, but also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the aforementioned features with (but not limited to) technical features with similar functions disclosed in this application.
