DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings:

[0020] Embodiment 1:

[0021] The present invention discloses an automatic brake oil replenishing device for a mechanical impact platform brake system, comprising an oil replenishing tank 1, a pressure spring mounting seat 2, a pressure spring 3, an oil replenishing pipe sealing cone 4, a sealing ball 5, an impact platform brake oil passage 6, an oil replenishing passage 7, and an oil replenishing pipe 8. The oil replenishing tank 1 is arranged above the impact platform brake oil passage 6, a refueling port 101 is arranged on the top of the oil replenishing tank 1, a sealing cover 102 is arranged at the refueling port 101, the oil replenishing tank 1 is connected to the impact platform brake oil passage 6 through the oil replenishing pipe 8, an oil replenishing passage 7 is arranged in the oil replenishing pipe 8, the oil replenishing passage 7 connects the oil replenishing tank 1 with the impact platform brake oil passage 6, the oil replenishing passage 7 is symmetrically provided with oil replenishing pipe sealing cones 4 on the upper and lower sides, an oil outlet 104 is arranged on the bottom plate 103 of the oil replenishing tank 1, a pressure spring mounting seat 2 is fixedly installed at the oil outlet 104, the pressure spring mounting seat 2 is connected to the oil replenishing passage 7 through the oil outlet 104, the sealing ball 5 is connected to the pressure spring mounting seat 2 through the pressure spring 3 The diameter of the sealing ball 5 is equal to or greater than the diameter of the minimum cross-section of the oil supply passage 7 .

[0022] Furthermore, the pressure spring mounting seat 2 is a truncated cone structure with a hollow bottom, and an oil drain groove is provided on the outer periphery of the truncated cone.

[0023] Furthermore, the number of the oil drain grooves 201 is N, N≥5, and the N oil drain grooves 201 are distributed at equal intervals.

[0024] Furthermore, the oil drain groove 201 is a circular structure, or a rectangular structure, or an oblong structure, or an elliptical structure.

[0025] Furthermore, when the pressure spring 3 is in a natural length state, the bottom of the sealing ball 5 does not contact the oil replenishment pipe sealing cone surface 4 on the lower side of the oil replenishment passage 7 .

[0026] Furthermore, the diameter of the oil outlet 104 is the same as the diameter of the minimum cross section of the oil supply passage 7 .

[0027] Embodiment 2:

[0028] This embodiment is based on the embodiment 1, and the similarities with the embodiment 1 are not repeated here, and only the differences are described: the upper part of the pressure spring mounting seat 2 is a truncated cone structure, and a support 202 is provided at the bottom of the truncated cone structure.

[0029] Furthermore, the number of the pillars 202 is N, N≥3, and the N pillars 202 are distributed at equal intervals.

[0030] Working principle: Inject a proper amount of brake oil 9 into the oil filling tank 1, and the brake oil 9 flows into a part of the oil filling channel 7 through the oil outlet 104 and the oil drain groove 201 or the support 202 on the pressure spring mounting seat 2. When the mechanical impact platform brake system is not running, the sealing ball 5 is under the pressure of the brake system brake oil and the oil filling pipe 8. The sealing ball 5 contacts the sealing cone surface 4 of the oil replenishing pipe inside, thereby closing the oil replenishing channel and preventing brake oil leakage. At this time, the pressure spring 3 is in a stretched state; when the mechanical impact platform brake system is running, the external impact force drives the pressure spring 3 to retract, and the sealing ball 5 leaves the sealing cone surface 4 of the oil replenishing pipe under the action of the pressure spring 3, and the oil replenishing tank 1 is connected to the impact platform brake oil channel 6, and the brake oil 9 enters the impact platform brake oil channel 6 from the oil replenishing tank 1 to play the role of oil replenishment. During the operation of the mechanical impact platform, the sealing ball 5 continuously contacts and separates from the sealing cone surface 4 of the oil replenishing pipe, so as to realize the continuous opening and closing of the oil replenishing channel 7, so as to discharge the air in the impact platform brake oil channel 6, and the brake oil 9 automatically flows into the impact platform brake oil channel 6, thereby completing the automatic oil replenishment work of the brake system.

[0031] The present invention can automatically replenish the brake oil of the brake system of the mechanical impact platform, and does not need regular manual oil replenishment maintenance, which solves the problem of low efficiency caused by manual replenishment and simplifies the brake oil supply process, so that the mechanical impact platform can work stably and continuously for a long time, and avoids the mechanical impact platform. Failure of the brake system due to lack of oil in the brake system and even over-testing occurs, which ensures the impact height control during the test and the stability of the test data.

[0032] The above description is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the scope of protection of the present invention.
