Referring to fig. 1 and 2, an embodiment of the present invention provides a rock drill test stand power station for powering two different tests, a performance test and a durability test, of a rock drill. The types of movement of the rock drill include the following: rotation of the rock drill, pushing of the rock drill, compensation of a pushing beam, translation of the pushing beam, lifting and clamping of rock and the like. The rock drill rig test stand power station may provide at least one or more of rock drill rig swing, thrust, cushioning, thrust beam compensation, thrust beam translation, rock lifting, rock clamping power for the performance test stand, as described below with reference to being able to provide all of the above power.
Referring to fig. 1 and 2, the rock drill rig test stand power station includes a support assembly 1, an oil tank assembly 2, and a power assembly 100. The support assembly 1 is configured to provide support. The tank assembly 2 is mounted to the support assembly 1. The powertrain assembly 100 includes a performance test bench powertrain 101 and a durability test bench powertrain 102, both mounted to the support assembly 1. The performance test bench power assembly 101 includes a first hydraulic system and a performance cooling cycle assembly 9 in communication.

The first hydraulic system and the second hydraulic system are communicated with the oil tank assembly 2; the performance cooling circulation assembly 9 and the durability cooling circulation assembly 19 are respectively communicated with the oil tank assembly 2 to cool the hydraulic oil entering the oil tank assembly 2.
The support assembly 1 provides a foundation for the installation of all other components of the rock drill test stand power station and also supports all other components of the rock drill test stand power station. Referring to fig. 1 and 2, the support assembly 1 includes a support plate and a support column located below the support plate. The support plate is generally rectangular. The number of the supporting columns is multiple, and the supporting columns are crisscrossed, so that each area of the supporting plate can be supported. The support assembly 1 may be provided with a running gear to effect a transition movement. The running mechanism is a common wheel, a universal wheel, an omni wheel and the like. The travelling mechanism is uniformly distributed at the bottom of the supporting component 1. Further, the supporting component 1 can be further provided with a locking mechanism, and when the transition transportation is not needed, the locking mechanism locks the travelling mechanism, so that the travelling mechanism cannot move.
The test bed power assembly 100 comprises a performance test bed power assembly 101 and a durability test bed power assembly 102, and can provide power for the performance test bed and the durability test bed. Referring to fig. 4, the performance test bench power assembly 101 and the durability test bench power assembly 102 each occupy about half of the area of the support member 1, except for the oil tank assembly 2. The oil tank assembly 2 is positioned in the middle area of the supporting component 1, the oil tank assembly 2 provides a basis for the installation of other components, and can also transmit cold to the components contacted with the oil tank assembly 2 to play a role in cooling.
Referring to fig. 1, 2 and 4, the oil tank assembly 2 is an important component of a power station of a rock drill test stand, and the oil tank assembly 2 is located at an intermediate position of the support member 1. The large size of the tank assembly 2 also provides support for components mounted to the tank assembly 2 and also provides cooling for those components. The performance cooling circulation assembly 9 is used for cooling heat generated by pressure loss and mechanical loss of each element in the first hydraulic system, so that the first hydraulic system maintains a stable temperature state.
According to the different functions of each part, the area of the test bed power station can be divided into a power area, a control valve area, a pressure flow detection area (an actuator) and a cooling oil return area. The power area is used for providing power; the control valve area is used for realizing control of the hydraulic system; the pressure flow detection area is used for realizing pressure detection and flow detection; the cooling oil return area is used for cooling the component. From the above-mentioned each regional division can see that the multiple functional of rock drill test bench power station can provide multiple power, can also cool down the cooling, detect pressure and flow.

Referring to fig. 3, the first performance motor pump assembly 3 specifically includes a first performance motor 31 and a first performance hydraulic pump 32 for providing impact power to the performance bench drill. The term "performance" is used herein to refer to the components of the performance test bench power assembly 101.

The first performance hydraulic pump 32 refers to a hydraulic pump that provides rotational hydraulic power for performance testing.
Referring to fig. 1 and 3, a first performance motor pump assembly 3 is located at one of the corners of the support member 1. Specifically, the first performance motor 31 and the first performance hydraulic pump 32 are arranged side by side along the edge of the support assembly 1, and are adjacent to each other.

The performance oil return converging block assembly 23 is used for converging hydraulic oil in each pipeline of the performance test bed power assembly 101 so as to facilitate the arrangement of the oil tank assembly 2, and on the other hand, the structure of the whole rock drill test bed power station is more compact.
Referring to fig. 8 and 9, in some embodiments, the first hydraulic system of the performance test bench power assembly 101 further includes a flow pressure detection assembly 103, the flow pressure detection assembly 103 being mounted between the rock drills to detect at least one of the following flow and pressure characteristics: buffering of the rock drill, impact oil drainage, impact of the rock drill, forward rotation of the rock drill, reverse rotation of the rock drill and flow and pressure characteristics of impact oil return. In some embodiments of the present invention, the flow pressure sensing assembly 103 may sense all of the flow and pressure characteristics described above. The rock drill is a test object of a rock drill test stand power station.
Both the performance test bench power assembly 101 and the durability test bench power assembly 102 are in communication with the flow pressure detection assembly 103, and the flow pressure detection assembly 103 can test the pressure and flow of any flow path flowing into the flow pressure detection assembly 103. The flow pressure sensing assembly 103 specifically includes a plurality of flow pressure sensing sensors in parallel.
