Embodiment Construction

[0017] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] see figure 1 , which is a structural schematic diagram of a static load impact test bench provided by an embodiment of the present invention. A static load impact test bench is mainly composed of a bearing frame 1, an automatic lifting mechanism 2 for a supporting device, a hydraulic station 3, and a comprehensive measurement and control system 4;

[0019] figure 2 It is an exploded view of the carrying platform provided by the embodiment of the present invention. The carrying platform 1 includes two vertically arranged support arms 101, a longitudinal oil cylinder 102, a transverse oil cylinder 103, a forward oil cylinder 104 and a support device fixing plate 105; The upper and lower ends of the two support arms 101 are prov...

Abstract

The invention provides a static load impact test bed. The static load impact test bed is mainly composed of a bearing rack (1), a supporting device automatic lifting mechanism (2), a hydraulic pressure station (3) and a comprehensive test and control system (4), wherein the bearing rack (1) comprises a vertical oil cylinder, (102), a horizontal oil cylinder (103) and a front oil cylinder (104) which are respectively used for longitudinal, transverse, front and back pressure durability and strength tests of a semi-trailer supporting device; and a pressure sensor electrically connected with the comprehensive test and control system (4) is arranged between the push rod and jacking block of each oil cylinder respectively and can monitor test pressure values in real time. With the static load impact test bed adopted, omnidirectional static pressure, strength and durability tests of the semi-trailer supporting device can be carried out, and a testing period can be effectively shortened.

Description

technical field [0001] The invention relates to the field of vehicle testing, in particular to a static load impact test bench for impact resistance, durability, front-rear and lateral strength and static pressure tests of semi-trailer support devices. Background technique [0002] A semi-trailer is a very widely used means of transportation in the modern transportation industry. When the semi-trailer is driving, its front end can be connected with the tractor to be supported and dragged by it. When not driving, the front end of the semi-trailer can be connected to the tractor Detachment, in order to support the front end of the semi-trailer after detachment, the bottom near the front end of the semi-trailer is often provided with a semi-trailer support device. The durability, front and rear and lateral strength and static load capacity of the semi-trailer support device directly affect the normal use of the semi-trailer, and the above-mentioned performance of the support de...
