Embodiment 1

[0036] Such as Figure 1-Figure 3 As shown, a fully automatic specific pressure measurement vehicle for circulating liquid injection, including a vehicle body and an improved single pillar detachably fixed on it;

[0037] The car body includes a carriage board 1, and the improved single pillar is detachably fixed on the carriage board 1, and a displacement measurement system, a hydraulic measurement system, a manipulator 2 and a storage box 3 are also arranged on the carriage board 1; the improved single pillar Respectively connected with displacement measurement system and hydraulic measurement system;

[0038] The improved single column is composed of an inner column 4 and an outer column 5 sleeved outside the inner column 4. The outer column 5 is a hollow structure with one end closed. The hollow part is an oil chamber 6. The inner column 4 is a structure with both ends closed. A top plate baffle 7 is provided, and a sealing plate 8 is provided at the other end. The sealing ...

Embodiment 2

[0051] A method for on-the-spot measurement of floor specific pressures at different locations of the entire roadway by using the automatic specific pressure measuring vehicle for circulating fluid injection of the present invention, comprising the following steps:

[0052] Step 1. Arrange measuring points: arrange a measuring point every 10m in the roadway area with flat terrain, and arrange a measuring point every 5m in the area where the slope of the terrain is greater than 8° or within 20m, and the difference between any height of the roadway is 500mm;

[0053] Step 2. Measurement: Use a fully automatic specific pressure measuring vehicle with circulating liquid injection, push it to the first measuring point, clean the bottom plate first, straighten the improved single pillar, and keep it in a vertical state. The bottom plate must be in full contact.

[0054] Open the valve on the high-pressure liquid injection pipe 16, it is advisable to pressurize the improved single pil...

Abstract

The invention discloses a cyclic liquid injection full-automatic specific pressure measurement vehicle which comprises a vehicle body and an improved monomer supporting column detachably fixed on the vehicle body, wherein the vehicle body comprises a compartment plate (1); the improved monomer supporting column is detachably fixed on the compartment plate (1); a displacement metering system, a hydraulic metering system, a manipulator (2) and an object storage box (3) are further arranged on the compartment plate (1); the improved monomer supporting column is connected with the displacement metering system and the hydraulic metering system. The cyclic liquid injection full-automatic specific pressure measurement vehicle injects liquid cyclically, and serves for the liquid injection work in the whole process by using existing emulsification liquid; as the improved monomer supporting column is arranged on the cyclic liquid injection full-automatic specific pressure measurement vehicle, a monomer does not need to be carried by workers on shoulders even if the working distance is thousands of meters long; therefore, the workload and the working intensity are greatly reduced; the object storage box can convey dozens of catty of pressure dies and other measurement components.

Description

technical field [0001] The invention relates to a mining machine, especially a circulating liquid injection full-automatic specific pressure measuring vehicle and a using method thereof when mining coal on a working face with weak floor conditions. Background technique [0002] The stope support system is composed of "bottom plate-bracket-roof". Under the impact of mining and the supporting pressure of the bracket (column), the bottom plate will be displaced, deformed and even damaged. When the bottom plate of the roadway is damaged, the roof will also be damaged. Even if a roof fall accident occurs, the damage of the bottom plate will further affect the support effect of the stope and the roadway, the support (column) may bottom out or tilt, the effective support force of the support (column) will be significantly reduced, and the sinking of the roof will increase. Detachment occurs at the top, and even a roof fall accident occurs, which may lead to the redistribution of gr...
