Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of bridge construction, and in particular relates to an intelligent material placing method for a cantilever beam-making machine. Background Art
[0002] In traditional bridge construction, concrete spreading operations often rely on manual operations. For example, the control of concrete pouring strength and concrete delivery volume mainly relies on the experience and on-site judgment of construction personnel, which not only increases labor costs, but also easily leads to errors due to human factors, affecting construction quality and efficiency. In addition, the traditional spreading method makes it difficult to ensure that concrete is evenly distributed on the cantilever structure. The concrete discharge speed and delivery volume are not easy to control. There may be too much concrete in some areas and insufficient concrete in some areas. This will affect the stress performance and stability of the bridge structure, and may cause safety hazards in the subsequent use process. At the same time, uneven spreading will increase subsequent finishing work and extend the construction period. In order to ensure construction quality and not delay the construction period, an intelligent spreading method for cantilever beam making machine was invented. Summary of the invention
[0003] In view of this, the invention aims to overcome the defects in the prior art and proposes an intelligent material distribution method for a cantilever beam-building machine. It is mainly aimed at the construction of a cantilever beam-building machine. When pouring concrete, the intelligent material distribution method of the cantilever beam-building machine is used to pour concrete in compartments. In order to determine the amount of concrete put in, the pouring time is determined by a flow meter, and the pouring strength is determined by a pressure sensor. The bottom plate of the box beam is poured first, and then the web of the box beam is poured to achieve precise material distribution. The cantilever continuous beam prestressed pipes in the prior art are densely packed. The traditional concrete pouring adopts the method of distributing the material from the top plate, which causes the corrugated pipe to be damaged and dry. At the same time, the concrete falls to the bottom plate at the high web position to cause segregation, resulting in the concrete being not dense after anchoring and the quality being difficult to control.
[0004] To achieve the above object, the technical solution created by the present invention is implemented as follows:
[0005] An intelligent material placing method for a cantilever beam making machine comprises the following steps:
[0006] S1. Two sets of distributors are symmetrically arranged, the feed pipe at the lower end of the distributor is extended to the bottom plate of the slow-setting soil to be poured, and an upper control valve and a lower control valve are arranged on the feed pipe;
[0007] S2. An upper branch pipe leading to the web to be cast is connected above the upper control valve corresponding to the feed pipe, and an upper branch pipe control valve is provided on the upper branch pipe. A lower branch pipe leading to the web to be cast is connected above the lower control valve corresponding to the feed pipe, and a lower branch pipe control valve is provided on the lower branch pipe.
[0008] S3. Pressure sensors are provided on the (outer) side wall of the lower end of the feed pipe, the (outer) side wall of the free end of the upper branch pipe, and the (outer) side wall of the free end of the lower branch pipe;
[0009] S4, open the upper control valve and the lower control valve, close the other valves, and pour the concrete base plate;
[0010] S5. After the flow meter reaches the specified value, close all valves. After the pressure sensor reaches the specified value, open the upper control valve and the lower branch pipe control valve, close the remaining valves, and pour the concrete web for the first time.
[0011] S6. After the flow meter reaches the specified value, close all valves. After the pressure sensor reaches the specified value, open the upper branch pipe control valve, close the remaining valves, and pour the concrete web for the second time.
[0012] Furthermore, the upper branch pipe leads to the upper half of the web to be cast.
[0013] Furthermore, the lower branch pipe leads to the lower half of the web to be cast.
[0014] Furthermore, the upper control valve, the lower control valve, the upper branch pipe control valve, and the lower branch pipe control valve are all electrically controlled valves.
[0015] Furthermore, the upper branch pipe is arranged obliquely downward, and its height gradually decreases from the side of the feed pipe to the side of the web to be cast.
[0016] Furthermore, the lower branch pipe is arranged obliquely downward, and its height gradually decreases from the side of the feed pipe to the side of the web to be cast.
[0017] Furthermore, each pressure sensor and each flow meter is electrically connected to a controller.
[0018] Furthermore, the controller includes a PLC.
[0019] Compared with the prior art, the present invention has the following advantages:
[0020] The intelligent material distribution method of the cantilever beam-making machine provided by the invention can ensure uniform distribution of concrete in the cantilever structure through precise sensor monitoring. The flow rate of concrete is measured in real time by the flow meter, and accurate material distribution is achieved, avoiding the problem of excessive or insufficient local concrete caused by manual operation or insufficient equipment precision in the traditional material distribution method. The strength of the poured concrete can be guaranteed by the pressure sensor, thereby ensuring the construction quality and making the bridge structure more evenly stressed and stable.

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.
[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0028] An intelligent material placing method for a cantilever beam making machine comprises the following steps:
[0029] S1. In the invention, the feed structure of the distributor is specially designed, such as Figure 1 and Figure 2As shown, two sets of distributors are symmetrically arranged, the feed pipe at the lower end of the distributor is extended to the bottom plate of the slow-setting soil to be poured, and an upper control valve and a lower control valve are arranged on the feed pipe;
[0030] S2. An upper branch pipe leading to the web to be cast is connected above the upper control valve corresponding to the feed pipe, and an upper branch pipe control valve is provided on the upper branch pipe. A lower branch pipe leading to the web to be cast is connected above the lower control valve corresponding to the feed pipe, and a lower branch pipe control valve is provided on the lower branch pipe.
[0031] S3. Pressure sensors are provided on the (outer) side wall of the lower end of the feed pipe, the (outer) side wall of the free end of the upper branch pipe, and the (outer) side wall of the free end of the lower branch pipe. The process of distributing materials using the above specially designed distributor feeding structure is as follows:
[0032] S4, open the upper control valve and the lower control valve first, close the other valves, and pour the concrete base plate;
[0033] S5. After the flow meter reaches the specified value, close all valves. After the pressure sensor reaches the specified value, open the upper control valve and the lower branch pipe control valve, close the remaining valves, and only pour the lower half of the concrete web for the first time;
[0034] S6. After the flow meter reaches the specified value, close all valves. After the pressure sensor reaches the specified value, open the upper branch pipe control valve and close the remaining valves. Only the upper half of the concrete web is poured for the second time.
[0035] The upper control valve, the lower control valve, the upper branch pipe control valve, and the lower branch pipe control valve are all electrically controlled valves. Each pressure sensor, each flow meter, and each control valve are electrically connected to a controller. As an example, the controller includes a PLC controller. The PLC controller receives the pressure sensor and each flow meter signal, and controls the corresponding control valve to open and close, thereby implementing steps S4-S6.
[0036] Preferably, the upper branch pipe leads to the upper half of the web to be cast. The lower branch pipe leads to the lower half of the web to be cast. The upper branch pipe is arranged obliquely downward, and its height gradually decreases from the side of the feed pipe to the side of the web to be cast. The lower branch pipe is arranged obliquely downward, and its height gradually decreases from the side of the feed pipe to the side of the web to be cast.
[0037] The intelligent material distribution method of the cantilever beam-making machine provided by the invention can ensure that the concrete is evenly distributed in the cantilever structure through accurate monitoring of various sensors. The flow meter measures the concrete flow in real time to achieve accurate material distribution, avoiding the problem of excessive or insufficient local concrete caused by manual operation or insufficient equipment precision in the traditional material distribution method. The pressure sensor can ensure the strength of the poured concrete, thereby ensuring the construction quality and making the bridge structure more evenly stressed and stable.
[0038] At the same time, precise distribution avoids the waste of concrete. Traditional distribution may require additional concrete to fill insufficient areas due to uneven distribution, or excessive distribution may lead to later cleaning and finishing. The intelligent distribution method can accurately distribute the required amount of concrete in the right place, improve the utilization rate of materials, and save material costs. It reduces the working time and frequency of construction personnel in dangerous environments (such as operating distribution equipment near the edge of the cantilever), and reduces the safety risks of personnel due to high-altitude operations, mechanical collisions, etc.
[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
