[0042] For better explaining the present utility model for easy understanding, the present utility model will be described in detail below in conjunction with the attached drawings through specific implementation manners. Among them, the orientation nouns such as "upper" and "lower" mentioned herein are with reference to Figure 1 the defined orientation.

[0043] Refer to Figure 1-4 , a support force detection mechanism for a hydraulic support proposed in an embodiment of the present utility model includes an underframe 1 and a loading mechanism 2.

[0044] The underframe 1 is detachably fixed on the base plate 5. The loading mechanism 2 is vertically oriented. The main body of the loading mechanism 2 is fixedly connected to the underframe 1. The loading end of the loading mechanism 2 can be detachably connected to the loading point 31 on the bottom wall of the top beam of the hydraulic support 3. The loading end of the loading mechanism 2 can move up and down relative to the main body of the loading mechanism 2, and the main body of the loading mechanism 2 can adjust the driving force for driving the loading end to move downward.

[0045] During use, first detachably fix the underframe 1 on the base plate 5, then fix the main body of the loading mechanism 2 on the underframe 1, and detachably connect the loading end of the loading mechanism 2 to the loading point 31 opened on the bottom wall of the top beam of the hydraulic support 3. Subsequently, the main body of the loading mechanism 2 adjusts the driving force for driving the loading end to move downward to adjust the downward pulling force applied by the loading end to the loading point 31 of the top beam of the hydraulic support 3. During the experiment, by observing whether the top beam of the hydraulic support 3 is damaged and cracked under this loading force, it can be judged whether the support force of the hydraulic support 3 meets the requirements. When the test at one loading point 31 is completed, disassemble the hydraulic support 3 and the support force detection mechanism, and move the support force detection mechanism to the position corresponding to another loading point 31 for re-detection.

[0046] Therefore, the assembly process of the support force detection mechanism of this hydraulic support is relatively convenient, with high safety, and can apply different downward pulling forces to the top beam of the hydraulic support 3, having a wide adjustment range to accurately simulate and test whether the bearing capacity of the hydraulic support 3 meets the requirements. At the same time, the support force detection mechanism of this hydraulic support can be reused with low cost.

[0047] Specifically, the loading mechanism 2 is a hydraulic cylinder. The main body of the loading mechanism 2 is the cylinder block of the hydraulic cylinder, and the loading end is the piston rod of the hydraulic cylinder.

[0048] During use, the cylinder block of the hydraulic cylinder can correspondingly change the driving force for driving the piston rod to move downward by adjusting the oil intake.

[0051] During use, the loading end of the loading mechanism 2 can be inserted into the suspension member 4 suspended on the loading point 31 and detachably connected to the suspension member 4.

[0052] Preferably, the lengths of the two holes 311 of the loading point 31 are different, so that the suspension member 4 can be inserted through the longer one of the two holes 311 and suspended on the loading point 31.

[0053] Specifically, multiple groups of loading point groups are spaced along the length direction of the top beam of the hydraulic support 3. Each loading point group includes at least one loading point 31 to detect the loading points 31 at different positions through the support force detection mechanism.

[0054] Preferably, the loading end of the loading mechanism 2 is provided with a horizontally oriented first connection hole 21, and the opposite side walls are flat surfaces. The suspension member 4 is provided with a horizontally oriented second connection hole 41, and the opposite inner side walls are flat surfaces, and...

When the loading end of the loading mechanism 2 and the suspension member 4 are connected, they are in flat contact, which can prevent relative rotation between the loading mechanism 2 and the suspension member 4 and improve the connection stability.

[0056] Furthermore, to improve the accuracy of applying a load to the top beam of the hydraulic support 3:

[0057] Optionally, a pressure gauge is provided on the hydraulic pipeline of the loading mechanism 2.

[0058] The pressure gauge can monitor the driving force for the main body of the loading mechanism 2 to drive the loading end to move downward according to the hydraulic oil quantity, and further monitor the load applied by the loading mechanism 2 to the top beam of the hydraulic support 3 via the suspension member 4, so as to increase the loading force value applied by the loading mechanism 2 to the hydraulic support 3.

[0059] Optionally, a pressure sensor is provided on the inner bottom wall of the top beam of the hydraulic support 3 between two adjacent holes 311 at the loading point 31, and the suspension member 4 can be hooked on the pressure sensor.

[0060] The pressure sensor can monitor the load applied by the loading mechanism 2 to the top beam of the hydraulic support 3 via the suspension member 4, so as to increase the loading force value applied by the loading mechanism 2 to the hydraulic support 3.

[0061] Preferably, a pressure gauge and a pressure sensor are provided in this support force detection mechanism to further improve the accuracy of applying the load to the top beam of the hydraulic support 3.

[0062] Furthermore, a U-shaped connecting seat 11 with an upward opening is provided at the top of the chassis 1.

[0063] The main body of the loading mechanism 2 can be inserted into the connecting seat 11 and detachably connected to the connecting seat 11.

The connecting seat 11 is provided with a horizontally oriented fourth connecting hole 111, and the opposite inner side walls are flat surfaces.

[0065] When the main body of the loading mechanism 2 is inserted into the connecting seat 11, the main body of the loading mechanism 2 and the connecting seat 11 are in flat contact, and the third connecting hole 22 communicates with the fourth connecting hole 111 and a pin is inserted through them in sequence, so as to conveniently realize the detachable connection between the main body of the loading mechanism 2 and the connecting seat 11. The flat contact between the main body of the loading mechanism 2 and the connecting seat 11 can prevent relative rotation between the loading mechanism 2 and the connecting seat 11 and improve the connection stability.

[0066] Furthermore, a support platform 12 that horizontally extends at the bottom of the chassis 1 and supports on the bottom plate 5 is formed, and a vertically oriented mounting hole 121 is provided on the support platform 12. A plurality of transverse grooves 51 are horizontally spaced on the bottom plate 5.

[0067] The support platform 12 of the chassis 1 supports on the bottom plate 5, and after the mounting hole 121 on the support platform 12 communicates with the transverse grooves 51, fasteners are inserted through them in sequence, so as to conveniently detachably fix the chassis 1 to the bottom plate 5.
