Description

Technical Field

[0001] The invention relates to the field of auxiliary devices for pouring concrete for pier bodies, and in particular to a simple and rotatable concrete pouring distributor. Background Art

[0002] With the rapid development of my country's transportation industry, railway bridge construction has entered a new development period, and the quality requirements for railway bridge construction are becoming more and more stringent. The construction of high piers is the most difficult, and the technical content is also relatively high. Safety hazards and various safety accidents are very likely to occur during the construction process. Therefore, there are very strict requirements for the construction of high piers of railway bridges. The bridge pier body bears the load transmitted from top to bottom of the bridge and transmits it to the foundation. Therefore, the role of the bridge pier body is very important, and it is particularly important to strictly implement construction technology and ensure its casting quality.

[0003] At present, the general method used in the concrete pouring construction of bridge piers is to use a concrete pump truck to pump concrete to the pouring site through the concrete pipe on the boom. With this method, when the cross-section of the pier is large, workers need to pour it many times, and more people are needed to pull the end of the pump pipe to adjust the pouring site. After the construction of a section of the pier, the equipment needs to be dismantled and transported to the new platform by a crane for assembly. The construction efficiency is extremely low, the construction difficulty is relatively large, and the project quality is difficult to control. During the pouring process, the crane needs to continuously control the steel pump pipe, which increases the investment in manpower, machinery and equipment, and funds. Summary of the invention

[0004] The present application provides a simple rotatable concrete pouring distributor, which can solve the technical problems in the prior art that when the cross-section of the pier body is large, workers need to move around for multiple times to pour the pier body, resulting in extremely low construction efficiency, great construction difficulty, and difficult to control project quality.

[0005] The embodiment of the present application provides a simple rotatable concrete pouring distributor, which includes:

[0006] A hollow funnel bracket, wherein a material distribution hopper is arranged on the hollow funnel bracket, and a material distribution mechanism is arranged at the material outlet of the material distribution hopper;

[0007] And, a fixed steel bracket, on which a rotary bearing is rotatably arranged, and the hollow funnel bracket is fixed on the central axis of the rotary bearing.

[0008] By adopting the above technical solution, the hollow funnel bracket is fixed on the central axis of the rotating bearing, so that the hollow funnel bracket can rotate on the fixed steel bracket through the rotating bearing. When pouring concrete, the operator can rotate the hollow funnel bracket to align the material distribution mechanism at the outlet of the material distribution hopper with different positions for material distribution and unloading operations, thereby completing the concrete pouring. This solves the problem that when the cross-section of the pier body is large, workers need to go back and forth for multiple pouring, the construction efficiency is extremely low, the construction difficulty is large, and the engineering quality is difficult to control.

[0009] In one embodiment, the material distribution mechanism includes a pump pipe arranged at the discharge port of the material distribution hopper, and a gate is arranged at one end of the pump pipe away from the material distribution hopper.

[0010] By adopting the above technical solution, when performing concrete pouring operations, a hose can be connected to the end of the pump pipe away from the distribution hopper. The construction personnel first rotate the hollow funnel bracket, direct the discharge end of the pump pipe toward the working area to be poured, and then hold the hose and open the gate on the pump pipe to accurately pour concrete in the working area to be poured.

[0011] In one embodiment, the material distribution mechanism includes a material distribution trough arranged at the discharge port of the material distribution hopper.

[0012] By adopting the above technical solution, the concrete feeding area is increased, which makes it more suitable for working conditions that require a large area to be filled with concrete and more convenient to use.

[0013] In one embodiment, the material dividing trough is composed of a plurality of segmented material dividing trough units, both ends of the material dividing trough units are provided with fixing ears, and the fixing ears of adjacent material dividing trough units are connected by connecting steel wires.

[0014] By adopting the above technical solution, the material distribution trough is composed of multiple sections of material distribution trough units, and the number of material distribution trough units can be freely adjusted to adapt to the distance between the position to be poured and the material distribution hopper outlet under different working conditions. Connecting steel wires are inserted into the fixed ears of adjacent material distribution trough units to enable the material distribution trough units to be tightly connected, reducing the possibility of slippage between adjacent material distribution trough units during the concrete distribution and unloading process.

[0015] In one embodiment, a material dividing trough support column is provided below the joint of adjacent material dividing trough units.

[0016] By adopting the above technical solution, the joints of the material distribution trough units are supported, thereby reducing the possibility of deformation of the material distribution trough units during the material distribution process.

[0017] In one embodiment, a support platform is provided below the fixed steel bracket, a plurality of positioning rings are provided on the support platform, and the positioning rings are connected to the fixed lifting ears by connecting steel wires.

[0018] By adopting the above technical scheme, since the bottom surface is relatively rugged during the concrete pouring process, the support platform can make the placement of the overall structure of the simple rotatable concrete pouring distributor more stable; after determining the concrete distribution direction, the distribution trough unit can be fixed on the operating platform using connecting steel wires, reducing the possibility of the distribution trough unit slipping on the operating platform during the concrete distribution process. There is no need for construction personnel to adjust the position of the distribution trough unit all the time, which makes it more convenient to use.

[0019] In one embodiment, a plurality of cushion beams are provided at the bottom of the support platform.

[0020] By adopting the above technical solution, the support platform can be more stably fixed on the bridge pier, reducing the possibility of movement of the support platform during the subsequent slow-setting soil distribution operation, making it more convenient to use.

[0021] In one embodiment, a pyramid reinforcement support is further provided below the fixed steel support, and the rotary bearing is fixed on the top of the pyramid reinforcement support.

[0022] By adopting the above technical solution, a more stable support can be provided for the material distribution hopper with a larger mass.

[0023] In one embodiment, a rotating handle is provided on the hollow funnel support.

[0024] By adopting the above technical solution, the rotating handle is firmly connected to the hollow funnel bracket through a high-strength welding process, ensuring a stable connection between the rotating handle and the hollow funnel bracket, and improving the safety of the overall structure. At the same time, the design of the rotating handle also fully considers the principles of ergonomics, and is designed to be in a shape and size that conforms to the hand-holding habits of construction personnel. Such a design not only provides an intuitive and comfortable force point for construction personnel, but also greatly improves the convenience of operation. Construction personnel only need to gently hold the rotating handle to easily realize the rotation of the hollow funnel bracket 1, without the need for additional tools or complicated operating steps, thereby saving time and labor costs and making it more convenient to use; in addition, the surface of the rotating handle can also be additionally anti-slip treated, even in a humid or oily working environment, it can ensure that the construction personnel hold it stably, effectively prevent accidents caused by slipping, and further improve the safety of construction. At the same time, the introduction of the rotating handle also enables construction personnel to more intuitively and accurately control the rotation angle when adjusting the discharging direction of the material distribution hopper, meeting the needs under various complex construction conditions.

[0025] In one embodiment, an auxiliary ladder is provided on the fixed steel support.

[0026] By adopting the above technical solution, construction workers can climb to the top of the feed port of the sub-hopper through the auxiliary ladder. Before carrying out the concrete unloading operation, they can observe the workability of the concrete in the sub-hopper and check whether the concrete has quality problems such as stratification or uneven mixing. When carrying out the concrete unloading operation, construction workers can also observe the concrete capacity in the sub-hopper by climbing the auxiliary ladder and replenish concrete in the sub-hopper in time to maintain the continuity of the concrete unloading operation, which is more convenient for construction workers to carry out the unloading operation.

[0027] The beneficial effects brought by the technical solution provided in the embodiments of the present application include:

[0028] By installing a fixed steel bracket on the bridge pier and using a rotating bearing to enable the hollow funnel bracket to rotate on the fixed steel bracket, the distributing mechanism at the discharging port of the distributing hopper can be aligned with different positions on the bridge pier, thereby completing the concrete pouring. This solves the problem that when the cross-section of the pier is large, workers need to move around many times to pour the concrete, resulting in extremely low construction efficiency, high construction difficulty, and difficult to control project quality.

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings 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.

[0035] The embodiment of the present application provides a simple rotatable concrete pouring distributor, which can solve the problem that when the cross-section of the pier body is large, workers need to move around for multiple times to pour the pier body, resulting in extremely low construction efficiency, great construction difficulty, and difficult to control project quality.

[0036] Embodiment 1:

[0037] Reference Figure 1 and Figure 2 The present application discloses a simple rotatable concrete pouring distributor, including a hollow funnel bracket 1 and a fixed steel bracket 2. A distributor hopper 11 is provided on the hollow funnel bracket 1, a distributor mechanism is provided at the outlet of the distributor hopper 11, a rotating bearing 21 is rotatably provided on the fixed steel bracket 2, and the hollow funnel bracket 1 is fixed on the central axis of the rotating bearing 21, so that the hollow funnel bracket 1 can rotate on the fixed steel bracket 2 through the rotating bearing 21. When pouring concrete, the operator can rotate the hollow funnel bracket 1 to align the distributor mechanism at the outlet of the distributor hopper 11 with different positions for distributor discharge operation, thereby completing the concrete pouring. It solves the problem that when the cross section of the pier body is large, workers need to go back and forth for multiple pouring, the construction efficiency is extremely low, the construction difficulty is large, and the engineering quality is difficult to control.

[0038] In this embodiment, the material distribution mechanism includes a pump pipe 111 disposed at the discharge port of the material distribution hopper 11, and a gate is disposed at one end of the pump pipe 111 away from the material distribution hopper 11. When performing concrete pouring operations, a hose can be connected to the end of the pump pipe 111 away from the material distribution hopper 11. The construction personnel first rotate the hollow funnel bracket 1, and direct the discharge end of the pump pipe 111 toward the working area to be poured, and then hold the hose and open the gate on the pump pipe 111 to accurately pour concrete in the working area to be poured.

[0039] Furthermore, in order to facilitate the construction workers to rotate the hollow funnel bracket 1 and adjust the feeding direction of the material distribution hopper 11, a rotating handle 23 is also welded on the hollow funnel bracket 1. The rotating handle 23 is firmly connected to the hollow funnel bracket 1 through a high-strength welding process, ensuring a firm connection between the rotating handle 23 and the hollow funnel bracket 1, thereby improving the safety of the overall structure. At the same time, the design of the rotating handle 23 also fully considers the principles of ergonomics, and is designed to be in a shape and size that conforms to the hand holding habits of the construction workers. Such a design not only provides an intuitive and comfortable force application point for the construction workers, but also greatly improves the convenience of operation. The construction workers only need to gently hold the rotating handle 23 to easily realize the rotation of the hollow funnel bracket 1, without the need for additional tools or complicated operating steps, thereby saving time and labor costs, and being more convenient to use.

[0040] In addition, the surface of the rotating handle 23 can be additionally treated with anti-slip treatment, which can ensure that the construction workers can hold it stably even in a humid or oily working environment, effectively preventing accidents caused by slipping, and further improving the safety of construction. At the same time, the introduction of the rotating handle 23 also enables construction workers to more intuitively and accurately control the rotation angle when adjusting the material discharging direction of the material distribution hopper, meeting the needs of various complex construction conditions.

[0041] Since the mass of the dividing hopper 11 is relatively large, in order to enable the dividing hopper 11 to maintain good stability and safety during operation, a pyramid reinforcement support 22 is also added to the fixed steel support 2. The pyramid reinforcement support 22 can not only effectively bear the weight of the hollow funnel support 1, the dividing hopper 11 and the concrete material inside the dividing hopper 11, but also resist external impact and vibration in a dynamic working environment. The bottom of the pyramid reinforcement support 22 is welded to the fixed steel support 2. This connection method not only ensures the firmness of the connection, but also avoids the possibility of loosening at the connection gap due to long-term use. During the welding process, it is necessary to follow the welding standards and procedures, use high-strength welding rods to ensure welding quality, and further improve the durability of the connection between the pyramid reinforcement support 22 and the fixed steel support 2. The rotating bearing 21 is rotatably set on the top of the pyramid reinforcement support 22, so that the dividing hopper 11 can be flexibly rotated or fine-tuned during construction to meet different construction needs. Furthermore, the selection of the rotary bearing 21 fully considers the wear resistance, load-bearing capacity and service life, so that the rotary bearing 21 can still maintain smooth rotation under long-term high-load operation.

[0042] More specifically, the pyramid reinforcement support 22 is made of steel structural material, which has the advantages of high strength, good deformation resistance and excellent corrosion resistance, so that the pyramid reinforcement support 22 has high strength while also greatly enhancing the ability of the pyramid reinforcement support 22 to resist external adverse factors, such as wind, vibration, etc. In addition, the pyramid reinforcement support 22 is set in the shape of a quadrangular pyramid. The shape of the quadrangular pyramid not only has good stability, but can more effectively disperse and bear the mass of the hollow funnel support 1, the distribution hopper 11 and the concrete material inside the distribution hopper 11, and also enhances the overall rigidity of the support structure through its geometric characteristics. Each side of the quadrangular pyramid is like a stable support point, and together they constitute a stable support system, providing all-round, multi-level protection and support for the hollow funnel support 1, the distribution hopper 11 and the concrete material inside the distribution hopper 11.

[0043] Since the bottom surface is relatively rugged during the concrete pouring process, in order to make the placement of the overall structure of the simple rotatable concrete pouring distributor more stable and reduce the shaking of the overall structure during the concrete pouring process, a support platform 3 is also provided at the bottom of the fixed steel bracket 2, and the support platform 3 is temporarily fixed on the surface of the bridge pier to provide a more stable placement surface for the fixed steel bracket 2; in this embodiment, an integral rigid frame is also provided above the support platform 3 to cover the hollow funnel bracket 1. When the construction personnel are performing concrete pouring operations, they can first install the fixed steel bracket 2 and the hollow funnel bracket 1 into the rigid frame of the support platform 3, and then use auxiliary tools to clamp the rigid frame on the support platform 3 to place the simple rotatable concrete pouring distributor on the ground at the construction site for easy installation and movement. During actual use, construction workers can also tie iron wire on the rigid frame of the support platform 3 and use the iron wire to connect the support platform 3 with other fixed workpieces at the construction site of the distribution hopper 11 to fix the support platform 3, thereby reducing the possibility of unstable support of the distribution hopper 11 and slipping of the support platform 3 on the construction surface.

[0044] Furthermore, in order to facilitate the construction personnel to monitor the concrete capacity in the distribution hopper 11 at any time during the concrete distribution process and replenish the concrete in the distribution hopper 11 in time, an auxiliary ladder 24 is also provided on the fixed steel support 2. The construction personnel can climb to the top of the feed port of the distribution hopper 11 through the auxiliary ladder 24. Before the concrete unloading operation, they can observe the workability of the concrete in the distribution hopper 11 and check whether the concrete has quality problems such as stratification or uneven mixing; when unloading concrete, the construction personnel can also observe the concrete capacity in the distribution hopper 11 by climbing the auxiliary ladder 24, and replenish concrete in the distribution hopper 11 in time to maintain the continuity of the concrete unloading operation, which is more convenient for the construction personnel to carry out the unloading operation. In this embodiment, the fixed ladder is welded to the fixed steel support 2 to reduce the possibility of the auxiliary ladder 24 slipping on the fixed steel support 2 during the concrete distribution process. In other embodiments, the auxiliary ladder 24 may be overlapped on the fixed steel support 2, and the auxiliary ladder 24 and the fixed steel support 2 may be fixed together using connecting wires or connecting ropes. The specific connection method may be flexibly adjusted according to actual working conditions.

[0045] Embodiment 2:

[0046] Reference Figure 3 A simple rotatable concrete pouring distributor provided in Example 2 of the present application is different from the simple rotatable concrete pouring distributor in Example 1 in that the distributor mechanism includes a distributor trough arranged at the discharge port of the distributor hopper 11, which increases the concrete discharge area and is more suitable for working conditions that require a large area of ​​concrete filling.

[0047] More specifically, the dividing trough is composed of a plurality of sections of dividing trough units 112, and the construction personnel can freely adjust the number of dividing trough units 112 to adapt to the distance between the position to be poured and the discharge port of the dividing hopper 11 under different working conditions. Fixed ears 113 are provided at both ends of the dividing trough units 112, and connecting steel wires are passed through the fixed ears 113 of adjacent dividing trough units 112, so that the dividing trough units 112 can be tightly connected to reduce the possibility of slippage between adjacent dividing trough units 112 during the concrete dispensing process. In other embodiments, the dividing trough can also be directly set as an integrally made dividing trough to make the concrete dispensing smoother and reduce the possibility of leakage of concrete during the dispensing process.

[0048] Since concrete will exert downward pressure on the trough unit 112 during the process of being distributed along the trough unit 112, in order to reduce the possibility of deformation caused by pressure at the joints of adjacent trough units 112, a trough support column 114 is also provided below the joints of the trough units 112, and the top of the trough support column 114 abuts against the bottom of the trough unit 112 to support the joints of the trough units 112, thereby reducing the possibility of deformation of the trough unit 112 during the distribution process. In this embodiment, a fixing hole is provided on the side wall at the top of the trough support column 114, and the fixing hole of the trough support column 114 is also fixedly connected to the fixing ear 113 of the adjacent trough unit 112 by a connecting steel wire, thereby reducing the possibility of slippage of the trough support column 114 during the concrete pouring process.

[0049] In this embodiment, the support platform 3 is configured as a rigid base plate, and a plurality of positioning rings 31 are provided on the support platform 3. The positioning rings 31 are also connected to the fixed ears 113 of the distribution trough unit 112 by connecting steel wires. After determining the distribution direction of the concrete, the distribution trough unit 112 can be fixed on the operating platform using the connecting steel wires, thereby reducing the possibility of the distribution trough unit 112 slipping on the operating platform during the concrete distribution process. There is no need for construction personnel to adjust the position of the distribution trough unit 112 all the time, and it is more convenient to use.

[0050] Furthermore, in order to enable the support platform 3 to be more stably fixed on the bridge pier, a plurality of cushion beams 32 are also provided at the bottom of the support platform 3. In the present embodiment, the cushion beams 32 are specifically made of fixed I-beams to more stably fix the support platform 3 on the bridge pier, thereby reducing the possibility of movement of the support platform 3 during the subsequent slow-setting soil distribution operation, and making it more convenient to use.
