Background technology
At present, the test-bed that the forklift door frame Stromeyer test is used adopts the monoblock type rigid structure, the ordinary test stand directly is cast in the concrete or with the foot bolt that is cast in the concrete and fixes, door frame is installed on the test-bed, the pull bar that can regulate with length replaces dump ram to adjust the angle of inclination of door frame, carry out torture test then, the fatigue strength of examination door frame.There is following defective in the test-bed of this kind structure: 1. test-bed is rigid unitary formula structure, tested door frame the installation dimension on the test-bed can't be adjusted to car load on consistent size, cause stressed not the conforming to the actual conditions of tie point (as the dump ram bearing), then can not examine the fatigue strength of tested door frame really.2. no matter test-bed is directly to be cast in the concrete or with the foot bolt that is cast in the concrete to fix, and stability is all relatively poor, rocks seriously when causing tested door frame to commutate, and the door frame force-bearing situation worsens more, is not inconsistent with actual applying working condition.3. the function of test-bed is comparatively single.
Summary of the invention
In order to solve operating condition of test and the car load actual applying working condition problem that be not inconsistent of forklift door frame on test-bed, the utility model provides a kind of test-bed that is used for forklift door frame examination Stromeyer test that improves structure.
The test-bed that is used for the forklift door frame Stromeyer test comprises flat base 1, and base 1 is provided with fore-stock 2 and after-poppet 6; Described base 1 is provided with the T type groove more than three; Described fore-stock 2 comprises horizonal base plate, offers U-shaped mounting groove respectively with the corresponding horizonal base plate of T type groove edge on the base 1, is laid with two upright support plates on the horizonal base plate, and the top of two support plates is provided with the stationary shaft 3 of level; Described after-poppet 6 is upright frame bracket, and end face is the plane, is laid with two rob supports 12 on the end face, rob support 12 is oblique triangle, and to fore-stock 2 lopsidedness, the upper end of each rob support 12 is connecting pull bar 14 by bearing pin 13, and pull bar 14 is rotatable; Two pull bars 14 lay respectively at the top of fore-stock 2.
Be provided with between described after-poppet 6 and the rob support 12 and adjust support 10 and/or adjust cushion block 11.
Spacing on the base 1 between the adjacent T type groove is 320 ㎜.
The utility model is compared with prior art products and is had the advantage of following aspect:
1. the installation dimension of forklift door frame on test-bed is the same with overall dimensions of a car, has guaranteed that the door frame stressing conditions is identical with actual condition, thus the fatigue strength of more real examination door frame;
2. panel size is enough big, makes the strong point reach that The whole test stand may tumble, and moves after the center of gravity, and stability is better, thus the shaking phenomenon when eliminating the door frame commutation;
3. consistent with car load operating mode height, hydraulic control system also adopts the banked direction control valves on the car load, in the time of examination door frame intensity, also can examine elements such as the stop valve in the portal frame system, governor valves simultaneously;
4. installation dimension is identical with car load, can simulate actual condition on test-bed dump ram is tested.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the test-bed that is used for the forklift door frame Stromeyer test comprises flat base 1, fore-stock 2 and after-poppet 6.Offer six T type grooves on the base 1, the spacing between the adjacent T type groove is 320 ㎜.Fore-stock 2 comprises horizonal base plate, offers U-shaped mounting groove respectively with the corresponding horizonal base plate of T type groove edge on the base 1, uniform on the horizonal base plate two upright support plates is installed, and the top of two support plates is equipped with the stationary shaft 3 of level by a flap 4.After-poppet 6 is upright frame bracket, the end face of after-poppet 6 is the plane, uniform on the end face two adjustment supports 10 are installed, each top of adjusting support 10 is equipped with rob support 12, rob support 12 is oblique triangle, and to fore-stock 2 lopsidedness, the upper end of each rob support 12 is connecting pull bar 14 by bearing pin 13, and pull bar 14 is rotatable; Two pull bars 14 lay respectively at the top of fore-stock 2.
