Description

Technical Field

[0001] The utility model relates to the technical field of concrete pumping, in particular to a multi-directional pressure and temperature monitoring device for concrete pumping. Background Art

[0002] Concrete material is the most common material in engineering construction at present. At the construction site, it is often necessary to transport concrete to the pouring site efficiently. Concrete pumping technology is to transport concrete through pressure pumps and delivery pipelines. Concrete pumping technology not only reduces labor consumption and greatly improves construction efficiency, but also can overcome the complex influence of the construction site environment through the layout of pipelines. Therefore, concrete pumping technology has become one of the most important and most commonly used technologies for concrete transportation in engineering construction. However, during the transportation process, concrete often faces problems such as pipe burst and pipe blockage caused by excessive pressure in the pipe and no timely treatment. At present, there is no more complete detection equipment on the market that can meet the pipe pressure detection problems encountered in actual projects.

[0003] The current concrete pumping pressure detection device is relatively simple. Usually, the number of pump pipe pressure collection points is designed according to the project scale and the pumping pipeline line, and then a point is randomly selected on the test pipeline for pressure detection. This monitoring method easily ignores the different pressure distributions faced by pumping pipelines in actual projects, that is, due to the gravity of the concrete itself, the pressure on the lower side of the pipeline is greater than that on the upper side; secondly, at the turning point of the pumping pipeline, since the concrete in the pipe has a certain speed, the pressure on the outer side of the turning point is also greater than that on the inner side. Therefore, it is insufficient to select only one point on the test pipeline for pressure detection, and it is difficult to better detect the overall pressure distribution in the pipe wall. In addition, monitoring the surface temperature of the pump pipe can play an auxiliary analysis role. On the basis of multi-directional pressure monitoring, temperature monitoring can greatly reduce the risk of pumping pipeline bursting. Therefore, the current pumping work requires a device that can monitor multi-directional pressure and temperature during concrete pumping. Utility Model Content

[0004] In view of the above problems, the utility model provides a multi-directional pressure and temperature monitoring device for concrete pumping to solve the problem that the existing concrete pumping pressure detection device does not take into account the effect of the concrete's own gravity and the influence on the pressure when encountering bends or crossing pipes during the pumping process, and utilizes temperature monitoring to make the monitoring device more comprehensive and complete.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a multi-directional pressure and temperature monitoring device for concrete pumping, including a test pumping pipeline, characterized in that: the test pumping pipeline is provided with a pressure testing component and a patch temperature sensor, the pressure testing component is arranged on the upper and lower sides of the straight pipe section and the outer side of the curved section of the test pumping pipeline, the pressure testing component is tightly installed on the threaded interface of the pipe wall through the threaded section, the signal output interface of the pressure testing component forms a multi-channel connection with the pressure acquisition device, the patch temperature sensor is installed on the inner side of the curved section of the pump pipe, the patch temperature sensor sticks the patch to the surface of the pump pipe through thermal conductive silicone, and is connected to the external device through a wire to transmit the temperature data of the pump pipe surface.

[0006] The patch temperature sensor consists of a patch, a temperature chip, a shielding wire and a conducting wire. The patch is attached to the surface of the pump tube. The temperature chip collects the surface temperature of the pump tube. The shielding wire is wrapped around the conducting wire, and the conducting wire is connected to an external device.

[0007] The pressure testing assembly is divided into three groups, respectively called pressure testing assemblies No. 1, No. 2 and No. 3. The pressure testing assembly No. 1 is installed at the upper end of the straight pipe section of the test pumping pipeline, and is the No. 1 monitoring point for monitoring the conventional pressure of the test pumping pipeline. The pressure testing assembly No. 2 is installed at the lower end of the straight pipe section of the test pumping pipeline, and is the No. 2 monitoring point for monitoring the influence of the concrete's own gravity on the pressure in the test pumping pipe. The pressure testing assembly No. 3 is installed on the outside of the curved section of the test pumping pipeline, and is the No. 3 monitoring point for monitoring the concrete pressure changes caused by the curved section of the test pumping pipeline.

[0008] The pressure testing component is internally provided with a pressure sensor, a threaded section and a pressure signal output interface, and is externally provided with a detachable bent threaded accessory suitable for a No. 3 pressure testing component. The pressure sensor is connected in parallel through a plastic cable tie via a pressure signal output line on the pressure signal output interface to form a multi-channel access signal input interface on a pressure acquisition device. The bent threaded accessory is provided with a threaded groove on the inner side and a threaded section on the outer side. It is installed on the pressure testing component through the inner threaded groove and is tightly combined with the pipe wall threaded interface through the outer threaded section.

[0009] The patch of the patch type temperature sensor is made of stainless steel, and the shielding wire is made of high temperature resistant material.

[0010] The test pumping pipeline has a threaded interface in the pipe wall, and a threaded groove is provided at the pipe wall threaded interface. The threaded groove is adapted to the size of the threaded section of the pressure test component. The two are tightly combined through the pipe wall threaded interface, and a sealing ring is installed on the upper contact surface of the pipe wall threaded interface.

[0011] The curvature of the surface of the detachable curved threaded fitting of the pressure test assembly is consistent with the curvature of the surface of the curved section of the pump tube, thereby ensuring the fit.

[0012] The installation positions of the pressure test assembly and the patch temperature sensor can be randomly adjusted according to the actual situation on site.

[0013] The outstanding advantages of the utility model are:

[0014] 1. Compared with traditional pressure testing devices, by considering the gravity of concrete itself and the influence of pipe bending section on pressure, the collected data is more accurate and comprehensive.

[0015] 2. Considering the effect of heat release from concrete hydration reaction on pipe wall temperature during concrete pumping, a patch temperature sensor is installed on the inside of the pump pipe bend to enable comprehensive analysis of concrete performance in the pipe.

[0016] 3. Compared with traditional pressure testing devices, by taking curved pipes into consideration, pressure monitoring can be unaffected by the shape and location of the pipe, and the performance of concrete in the pipe can be accurately analyzed. BRIEF DESCRIPTION OF THE DRAWINGS

The surface temperature of the pump tube can be viewed in real time by logging into the corresponding web page. When the pressure difference begins to change, the change in the surface temperature of the pump tube can be observed to assist in determining whether the pump tube is blocked.

[0028] The pressure test assembly 2 is divided into three groups, respectively called pressure test assemblies No. 1, No. 2 and No. 3.

The pressure test component 2 can collect and transmit pressure data in real time through the pressure acquisition device 5.
