Description

Technical Field

[0001] The utility model relates to the field of loading test equipment, in particular to a horizontal loading test bench with an inlet and outlet device. Background Art

[0002] As an important supporting equipment in coal seam mining, hydraulic support is mainly used to support the mining working face. The hydraulic support mainly includes supporting columns, top beams, tail beams, shield beams, front beams and bases. Hydraulic supports need to complete various tests before leaving the factory, one of which is the horizontal loading test, which can be divided into front horizontal loading test and rear horizontal loading test. At present, some test benches do not have front and rear fixed support for the top beam of the hydraulic support, or some test benches do not have front and rear fixed support for the base of the hydraulic support, resulting in the inability to complete the test requirements. At the same time, the entry and exit of the test bench support is achieved through the entry and exit plate, and the entry and exit plate realizes the entry and exit test through the telescopic jacks on both sides. Therefore, the entry and exit plate is movable when entering and exiting the support, and when horizontal loading is performed, horizontal force needs to be provided to the hydraulic support, which requires the entry and exit plate to be fixed, and the existing entry and exit plate cannot achieve this function.

[0003] In order to improve the fixing firmness of the hydraulic support horizontal loading test bench during the test, the invention patent with the authorization announcement number CN108801667B discloses a hydraulic support test bench base, including a base, a placement area for placing the base of the hydraulic support on the base, a lifting unit for lifting the base of the hydraulic support in the placement area, bottom adjustment mechanism loading units are respectively installed on both sides of the placement area, and the loading directions of the bottom adjustment mechanism loading units on both sides are arranged relatively. The base is also provided with a push rod side loading unit for performing a side loading test on the push rod of the push mechanism, and a push rod adaptability test unit for performing a deflection test on the push rod of the push mechanism. This setting can meet the requirements of testing the performance of the mechanism at each position on the base, so that the overall performance of the base has a high stability. However, when the device is fixed, it is mainly fixed by the push rod, the push rod slot, the positioning pin and the positioning hole, which has high installation requirements and the installation position cannot be adaptively adjusted.

[0005] A top base is arranged on the top of the loading frame, and a plurality of upper T-slots are arranged on the lower surface of the top base, wherein a plurality of upper T-slot stoppers are arranged side by side in one of the upper T-slots, and a front fixing plate is arranged at one end of the top base.

[0006] Based on the above, in order to facilitate the adjustment of the installation position of the hydraulic support, the plurality of lower T-slots are arranged at equal intervals.

[0007] Based on the above, in order to facilitate the adjustment of the installation position of the hydraulic support, the plurality of upper T-slots are arranged at equal intervals.

[0008] Based on the above, the plurality of bolt holes are arranged at equal intervals.

[0009] Based on the above, in order to facilitate installation and disassembly, the front fixing plate is detachably arranged at one end of the top base.

[0010] Based on the above, the front fixing plate is detachably arranged at one end of the top base via a pair of pins.

[0011] Based on the above, in order to ensure the firmness of the fixing of the access plate and the uniformity of the force, the plurality of bolt holes are arranged in two rows on the access plate.

[0012] Based on the above, a plurality of pairs of the triangular fixing blocks are located between the two rows of bolt holes.

[0013] Based on the above, in order to ensure that the top of the hydraulic support can be effectively limited, the arrangement width of the plurality of upper T-slot stoppers is greater than the width of the top of the hydraulic support.

[0014] Among them, telescopic jacks are externally connected to both sides of the access plate, and the access plate realizes the access test through the telescopic jacks on both sides. During the test, the installation position of the hydraulic support can be adaptively adjusted by changing the fixed position of the access plate.

[0015] The utility model has substantial features and progress over the prior art. Specifically, the horizontal loading test bench with an entry and exit device provided by the utility model respectively arranges a front triangular fixing block and a rear triangular fixing block at the front and rear positions of the entry and exit plate, thereby ensuring that during the horizontal loading test, the front triangular fixing block and the rear triangular fixing block can be used to support the two ends of the bottom of the hydraulic support respectively. At the same time, a plurality of lower T-slots are opened on the bottom base, mounting holes are opened on the entry and exit plate, and the entry and exit plate are fixedly connected to the lower T-slots by using the lower T-slot fixing blocks. While improving the fixing firmness of the entry and exit plate, the position of the entry and exit plate can also be adjusted.

[0016] Furthermore, by providing a plurality of upper T-slots on the top base and installing upper T-slot blocks in the upper T-slots, the upper T-slot blocks can be used to horizontally support one end of the top of the hydraulic support. By providing a front fixing plate at the other end of the top base, the front fixing plate can be used to horizontally support the other end of the top of the hydraulic support, thereby reducing the difficulty of installing the hydraulic support when horizontally loaded.
