Description

Technical Field

[0001] The utility model relates to the technical field of concrete construction, in particular to a concrete volume detection mechanism. Background Art

[0002] In tunnel pouring and other concrete pouring construction environments, concrete is mostly poured using concrete pumps such as trailer pumps (ground pumps) and sky pumps. Concrete pumps generally use hydraulic devices to push pistons to squeeze the concrete inside the concrete cylinder, thereby pumping the concrete to the desired position or height through the pump pipe.

[0003] Most of the existing concrete pouring equipment does not have the function of concrete volume statistics. However, as a key indicator among various indicators such as construction quality and construction budget verification, more and more construction units use this function as a key parameter and as an equipment procurement indicator for bidding.

[0004] At present, the method of measuring the volume of concrete in the process of concrete pouring construction is usually to multiply the volume of the concrete cylinder by the number of pumping times. That is, how to measure the number of pumping times in the process of concrete pouring construction has become a key issue. The existing methods of measuring the number of pumping times are:

[0005] 1. The reciprocating times of the hydraulic piston are detected by the induction switch, but the working environment of the hydraulic piston is bad, which generally means a large amount of concrete, sewage and oil, which interferes with the normal detection of the induction switch, resulting in low detection accuracy and easy damage to the induction switch;

[0006] 2. The number of times the hydraulic pressure of the hydraulic device rises is detected by the pressure sensor, but the hydraulic devices of various construction equipment are not uniform when they leave the factory, and the oil pressure can also be adjusted, so the oil pressure threshold cannot be set accurately, resulting in pumping calculation errors;

[0007] 3. The vibration frequency of the concrete pump is detected by a vibration sensor, but the working environment of the concrete pump is also harsh. After the vibration sensor is installed on the concrete pump, it is easily affected by concrete, sewage and oil, resulting in low detection accuracy and easy damage to the vibration sensor. Utility Model Content

[0008] In view of the above-mentioned deficiencies in the prior art, the utility model provides a concrete volume detection mechanism, which is not only simple in structure and can be quickly installed, but also can measure the number of pumping times during the concrete pouring construction process with high precision, thereby realizing accurate detection of the concrete volume.

[0009] To achieve the above-mentioned purpose, the utility model provides a concrete volume detection mechanism, including a pumping mechanism, a pumping pipe and a vibration sensor;

[0010] The first end of the pumping pipe is connected to the pumping mechanism, and the second end of the pumping pipe is located at the concrete pouring position;

[0011] The vibration sensor is arranged on the pumping pipe to measure the vibration intensity signal of the pumping pipe.

[0012] In one embodiment, the vibration sensor is located on the pumping tube and away from the second end of the pumping tube.

[0013] In one embodiment, the vibration sensor is located in the middle of the pumping tube.

[0014] In one embodiment, a mounting base is fixedly provided on the outer wall of the pumping pipe, and the vibration sensor is arranged on the mounting base.

[0015] In one embodiment, the mounting base is welded to the outer wall of the pumping pipe.

[0016] In one embodiment, the mounting base is adsorbed onto the outer wall of the pumping tube via a magnetic structure.

[0017] In one embodiment, the shock sensor is threadedly connected to the mounting base.

[0018] In one embodiment, the vibration sensor is adsorbed on the mounting base through a magnetic attraction structure.

[0019] In one embodiment, the concrete volume detection mechanism further includes a protective cover, which is detachably connected to the pumping pipe and covers the vibration sensor.

[0020] In one embodiment, there are multiple shock sensors.

[0021] Compared with the prior art, the utility model has the following beneficial technical effects:

[0022] 1. The utility model installs the vibration sensor on the pumping pipe and obtains the pumping times by measuring the vibration intensity signal of the pumping pipe, so that the vibration sensor is kept away from areas with serious pollution such as concrete pumps, thereby reducing the damage probability of the vibration sensor. At the same time, the pumping times in the concrete pouring construction process can be measured with high precision, thereby realizing accurate detection of the concrete volume;

[0023] 2. In the preferred embodiment of the present invention, the vibration sensor can be installed on the pumping pipe through the magnetic attraction structure, so the installation position of the vibration sensor can be flexibly adjusted according to specific construction conditions, so that it is suitable for more construction scenarios.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, a physical connection, or a wireless communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] like Figure 1 The figure shows a concrete volume detection mechanism disclosed in this embodiment, which mainly includes a pumping mechanism 1, a pumping pipe 2 and a vibration sensor 3. Among them, the first end of the pumping pipe 2 is connected to the pumping mechanism 1, the second end of the pumping pipe 2 is located at the concrete pouring position, and the vibration sensor 3 is arranged on the pumping pipe 2 to measure the vibration intensity signal of the pumping pipe 2.

[0034] The pumping mechanism 1 is mainly used to provide pressure for the concrete that needs to be pumped. The pumping pipe 2 is connected to the pumping mechanism 1 and is used to guide the concrete to the concrete pouring position. Since it takes a lot of force to smoothly pump the concrete to the expected position, the pumping pipe 2 often has a strong vibration during pumping. Therefore, in this embodiment, the vibration sensor 3 is installed on the pumping pipe 2 to detect the vibration intensity signal generated by the pumping pipe 2 when the concrete is pumped, and then the vibration intensity signal detected in real time by the vibration sensor 3 is transmitted to the single-chip microcomputer as the detection terminal.

[0035] Each time concrete is pumped, the vibration intensity of the pumping pipe 2 gradually increases from 0 until it reaches a peak value, and then returns to 0 as the pumping ends. Therefore, a signal detection circuit can be preset on the single-chip microcomputer. When the vibration intensity signal measured by the vibration sensor 3 exceeds the set threshold and then falls below the set threshold once, the number of pumping times is determined to be increased by 1, and the number of pumping times can be accurately obtained. Figure 2 For example, Figure 2 The X-axis represents time, and the Y-axis represents the vibration intensity signal detected by the vibration sensor 3 . Figure 2 The vibration intensity signal exceeds the set threshold four times, that is, the surface is pumped four times during this period of time, and the volume of the poured concrete can be obtained by multiplying the number of pumping times by the volume of the concrete cylinder. As for setting a signal detection circuit on the single chip microcomputer to detect the change in signal intensity, it is a prior art in the field, so it will not be described in detail in this embodiment.

[0036] As a preferred embodiment, the vibration sensor 3 is located on the pumping pipe 2 and away from the second end of the pumping pipe 2, and the vibration sensor 3 is located in the middle of the pumping pipe 2, so that the vibration sensor 3 is away from the pumping mechanism 1, the concrete pouring position and other areas with more serious pollution, thereby reducing the probability of the vibration sensor 3 being contaminated and improving the detection accuracy of the pumping times.

[0037] refer to Figure 3, a mounting base 4 is fixedly provided on the outer wall of the pumping pipe 2, and the vibration sensor 3 is arranged on the mounting base 4. Among them, the mounting base 4 can be adsorbed on the outer wall of the pumping pipe 2 by welding or by a magnetic structure, and the vibration sensor 3 is adsorbed on the mounting base 4 by a threaded connection or by a magnetic structure. It is preferred to connect the mounting base 4 and the pumping pipe 2 by magnetic attraction, so that the installation position of the vibration sensor 3 on the pumping pipe 2 can be flexibly adjusted according to the specific construction conditions, so that it can be applied to more construction scenarios. Of course, in the specific application process, the vibration sensor 3 can also be directly installed on the pumping pipe 2 by clamping, binding or magnetic attraction.

[0038] As a preferred embodiment, the concrete volume detection mechanism further includes a protective cover, which is detachably connected to the pumping pipe 2 and covers the vibration sensor 3 to prevent the vibration sensor 3 from being contaminated or interfered with. In a specific application process, the protective cover can adopt an annular buckle structure so that the protective cover is sleeved on the pumping pipe 2 and covers the vibration sensor 3 at the same time.

[0039] In the specific implementation process, the number of vibration sensors 3 can be set to multiple, preferably more than three. Each vibration sensor 3 is set on the pumping pipe 2 along the reversing interval, and multiple pumping times are measured by multiple vibration sensors 3, and the result corresponding to the majority is selected as the final pumping time to improve the detection accuracy.

[0040] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
