Abstract
The utility model belongs to the technical field of coal mine product test apparatuses and specifically relates to a falling weight impact testing stand, solving the problem that conventional test stands for impact tests are incapable of meeting the needs of the impact tests for coal mine products. The falling weight impact testing stand comprises a body, a base, an upper platform, and a lower platform. The base is mounted on the upper platform and comprises a cabinet form frame, a drive stepping motor, two screw rods, and two polished rods. The body comprises two parallel guide pipes fixedly connected with the bottom of a mounting seat, an impact height adjusting transmission device, a weight body, and a secondary impact preventing device. The beneficial effects of the falling weight impact testing stand are that: the falling weight impact testing stand is applicable to tests of test samples in various sizes and does not affect the transportation due to space problems, and the tests can be conducted after simply placing the test samples onto the lower platform through a forklift.
Description
Technical field
The utility model belongs to the technical field of colliery product testing device, is specifically related to a kind of drop hammer type shock test bench.
Background technology
Not of uniform size, different because of the colliery series products, testing table requires that various test products are had general adaptability.According to investigation, at present domestic such shock table is all falling weight impact tests of carrying out for tubing, but the pipe-type test specimen is less, so the narrow space of testing table installation test sample can not satisfy the needs of coal mine explosion-proof electric product.
Summary of the invention
The utility model can not satisfy the problem of the needs of colliery product impulse test for the testing table that solves existing impulse test, and a kind of drop hammer type shock test bench is provided.
The utility model adopts following technical scheme to realize:
Drop hammer type shock test bench comprises fuselage, support, upper platform and lower floor's platform of placing test specimen,
Described support is installed on upper platform, support comprises casing shape framework, Driving Stepping Motor and two leading screws, two polished rods, the output shaft of Driving Stepping Motor connects respectively two leading screws by the chain transmission, all supporting on two leading screws have a nut, two nuts connect by mount pad, also be provided with two pilot holes on mount pad, two pilot holes are placed in respectively to consist of on polished rod and are slidably matched;
Described fuselage comprises two parallel guide pipes, shock height adjustment gearing, hammer body and the anti-secondary pulse device that is fixedly connected with bottom mount pad, guide pipe top arranges shock height and adjusts gearing, hammer body is set, the anti-secondary pulse device of guide pipe exit installation in guide pipe.
The relative prior art of the utility model has following beneficial effect: this device is broad because of its riding position, and interfere without miscellaneous part the installation site, and the test specimen that can be applicable to all size is tested.Need the test specimen of forklift transport also more to have superiority for the colliery with heavier test specimen in addition, because its test specimen installation site is broad, can because space problem affects transportation, only not need the test specimen fork is put on platform and can tests.
Description of drawings
Fig. 1 is structural representation of the present utility model,
In figure: the 1-support, 2-fuselage hoisting gear, 3-leading screw group, the 4-shock height is adjusted gearing, 5-upper platform, 6-fuselage, 7-guide pipe, 8-hammer body, 9-test specimen, 10-lower floor platform.
Embodiment
By reference to the accompanying drawings embodiment of the present utility model is described further.
Drop hammer type shock test bench comprises fuselage 6, support 1, upper platform 5 and lower floor's platform 10 of placing test specimen 9, as shown in Figure 1.
Lower floor's platform fixedly is placed on ground, is used for the installation test sample.
At the trial, first fuselage is risen, then will test sample and be placed on lower floor's platform, then fuselage is dropped to suitable position, then promote hammer body and test.
