Description

Technical Field

[0001] The utility model belongs to the technical field of shield machines, and in particular relates to a detection device for the function of a flow meter of a shield machine. Background Art

[0002] The shield machine is designed with a large number of fluid systems. While the shield machine is excavating, different fluid systems provide flow to the actuators of each system through pipelines to ensure that each system completes the designed function or action. As the shield machine's excavation distance increases, the flow meters related to the shield machine are also likely to age and be damaged. When the shield machine is repaired, the aged or damaged flow meters need to be replaced. Among them, how to quickly and efficiently determine whether a flow meter is functioning properly is a very important task.

[0003] In view of this, in order to solve the above problems, the utility model designs a detection device for the flow meter function of a shield machine. Utility Model Content

[0014] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0015] Embodiment 1, according to Figure 1-Figure 3 Provide further explanation.

[0016] The utility model provides a detection device for the flow meter function of a shield machine, comprising a cart 2, a water tank 1 is fixedly installed on the upper surface of the cart 2, a water pump 3 is installed at the bottom of the interior of the cart 2, a ball valve 5 is fixedly installed at the bottom of the water tank 1, a tee 6 is fixedly installed on the outside of the cart 2, a standard flow meter 4 connected to the tee 6 is fixedly installed on the outside of the cart 2, and a first flange 7 and a second flange 8 are respectively connected to the top of the standard flow meter 4. The ball valve 5, water pump 3, tee 6, and standard flow meter 4 are connected in sequence through pipelines. The standard flow meter 4 is connected to the first flange 7 and the second flange 8 through two sets of pipelines respectively. The first flange 7 is a one-inch standard flange interface, and the second flange 8 is a two-inch standard flange interface. The flow meter interface commonly used in shield machines is one-inch or two-inch; the tee 6 is a water source connection port; the ball valve 5 is a water drain ball valve 5 of the water tank 1. This ball valve 5 is kept closed when not in use and opened when in use, so that the water pump 3 can normally pump water from the water tank 1; the cart 2 is a device for placing the water tank 1, which is welded from I-beams to ensure sufficient strength; the water pump 3 provides flow for flow meter detection. When the flow meter needs to be detected, this water pump 3 can draw water from the water tank 1 to supply the flow required by the flow meter.

[0017] When the flow meter to be tested needs to be tested, first fill the water tank 1 with water, then the operator pushes the cart 2 to move the whole device to the flow meter to be tested, and then connects the flow meter to be tested with the corresponding flange according to the size of the flow meter to be tested. When the interface size of the flow meter to be tested is one inch, the flow meter to be tested is connected to the first flange 7, and when the interface size of the flow meter to be tested is two inches, the flow meter to be tested is connected to the second flange 8, and then the water pump 3 is turned on. The water pump 3 draws the water in the water tank 1 from the ball valve 5 and enters the inside of the water pump 3 through the pipeline. The water is then transported to the tee 6 by the water pump 3. The lower pipeline of the tee 6 is closed by the ball valve 5, so that the water sent by the water pump 3 can only flow through the tee 6, pass through the standard flow meter 4, and then enter the flow meter to be tested through the pipeline. In this way, it can be ensured that the pipelines of the standard flow meter 4 and the flow meter to be tested are full of water flow, among which the standard flow meter 4 is used as a reference model of the flow meter to be tested (the standard flow meter 4 is a flow meter with good functions). Then, by comparing the displayed readings of the flow meter to be tested and the standard flow meter 4, it can be known whether the function of the flow meter to be tested is good.

[0018] As a specific implementation of the utility model, a pulley is installed at the bottom of the cart 2.

[0019] By rotatably connecting a pulley at the bottom of the cart 2, it is convenient for an operator to push the cart 2, thereby reducing the difficulty for the operator to move the entire device.

[0020] As a specific implementation of the utility model, a dust cover is provided on the top of the water tank 1.

[0021] By arranging a dust cover on the top of the water tank 1, it is prevented that foreign matters etc. enter the water tank 1 and thus pollute the water source.

[0022] As a specific implementation of the utility model, lifting ears are provided on both sides of the water tank 1.

[0023] By designing lifting ears on both sides of the water tank 1, the movement and lifting of the water tank 1 are facilitated.

[0024] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
