Description

Technical Field

[0001] The utility model relates to the technical field of pressure detection, in particular to a pressure detection device for the outlet of a filling pump. Background Technique

[0002] At present, during the working process of various concrete pumps, due to the setting and easy wear characteristics of concrete, the pressure at the outlet of the concrete pump cannot be detected by a ready-made pressure gauge or pressure sensor.

[0003] In the Chinese utility model patent application publication specification CN207231697U, a pressure detection device for the outlet of a coal mine paste filling pump is disclosed. The pressure detection device includes: a piston, a sleeve, a plug, and a pressure gauge; the sleeve is welded on the pumping pipeline, a piston is installed at one end of the sleeve, and there is an O-ring on the piston; a plug is installed at the other end of the sleeve, there is an installation hole on the plug, and a pressure gauge is connected to the installation; there is a gap between the piston and the plug, and there is emulsion in the gap; the installation hole on the plug communicates with the gap between the piston and the plug. The concrete in the pumping pipeline is completely isolated, the cavity in the sleeve is filled with emulsion, and a pressure gauge or a pressure sensor is installed on the plug. When there is pressure in the paste in the pipeline, the pressure is transmitted to the emulsion through the piston and then to the pressure gauge or the pressure sensor. The detection device: does not allow the concrete to directly contact the pressure gauge or the sensor, avoiding the pressure gauge or the sensor being easily damaged. Advantages: The pressure measuring device has a simple structure, low cost, and is durable and not easily damaged.

[0004] This existing technical solution still has the following problems when in use:

[0005] 1. The disassembly of the sensor of this device is relatively troublesome and laborious when maintenance or replacement is required;

[0006] 2. When the pressure is too high, there is a probability that the piston and the plug will be pushed out, causing leakage of the pumping pipeline;

[0007] Therefore, improvements need to be made to the above problems. Content of the Utility Model

[0008] The purpose of the utility model is to provide a pressure detection device for the outlet of a filling pump to solve the problems raised in the above background technique.

[0009] To achieve the above object, the present utility model provides the following technical solution: A filling pump outlet pressure detection device, including a pumping pipeline, an inner conveying chamber is provided inside the pumping pipeline, a sleeve is fixedly arranged on the top of the pumping pipeline, the inside of the sleeve is communicated with the conveying chamber, a movable cylinder is arranged on the top of the sleeve, a threaded groove is arranged on the inner wall of the top of the sleeve, a threaded ring is fixedly arranged at the bottom of the movable cylinder, the movable cylinder is threadedly connected with the sleeve, a test chamber is arranged inside the movable cylinder, and a first piston is movably arranged inside the test chamber.

[0010] Preferably, a first sealing rubber ring is fixedly arranged around the first piston, and a pressure sensor is arranged on the top of the first piston.

[0011] Through the above solution, by arranging the first sealing rubber ring, it is prevented that the emulsion passes through the gap between the first piston and the test chamber.

[0012] Preferably, the pressure sensor penetrates through the top of the movable cylinder, and a pressure gauge is arranged on the top of the pressure sensor.

[0013] Through the above solution, by arranging the pressure sensor to measure the pressure and feed back the pressure value to the pressure gauge.

[0014] Preferably, the pressure gauge is electrically connected with the pressure sensor, and emulsion is arranged inside the sleeve.

[0015] Through the above solution, by arranging the emulsion, the pressure sensor is prevented from contacting the concrete.

[0016] Preferably, a second piston is movably arranged inside the sleeve, and a plug is fixedly arranged at the bottom of the second piston.

[0017] Through the above solution, by arranging the plug, it plays a role in initially isolating the inside of the conveying chamber and the sleeve.

[0018] Preferably, a second sealing rubber ring is fixedly arranged around the second piston, a fixing ring is fixedly arranged around the movable cylinder, a handle is fixedly arranged on one side of the fixing ring, and anti-slip lines are fixedly arranged on the surface of the handle.

[0019] Through the above solution, by arranging the handle, it is convenient to rotate the fixing ring more easily, so that the movable cylinder can be turned open more easily.

[0020] Compared with the prior art, the beneficial effects of the present utility model are:

[0021] 1. When the outlet pressure detection device of a filling pump is in use, first, concrete passes through the inside of the pumping pipeline, thereby generating pressure on the pumping pipeline, squeezing the second piston inward, continuously transmitting the pressure to the emulsion liquid, and the emulsion liquid further transmits the pressure to the first piston. The first piston moves upward and squeezes the pressure sensor, so that the pressure sensor transmits the detected data to the pressure gauge for feedback. The above design isolates the contact between the pressure sensor and the concrete, thereby increasing the service life of the sensor.

[0022] 2. For the outlet pressure detection device of a filling pump, by rotating the handle, the fixed ring and the movable cylinder rotate together. Due to the threaded connection between the threaded groove and the threaded ring, the movable cylinder and the sleeve can be easily disassembled and fixed. Thus, when the pressure sensor is damaged or needs to be repaired, it can be quickly disassembled. At the same time, the design of the handle makes the rotation of the device more labor-saving, and the threaded connection between the movable cylinder and the sleeve is more stable. When the pressure in the pumping pipeline is too high, it will not impact the detection device, avoiding leakage of the pumping pipeline. Description of the Drawings
