Abstract
The utility model belongs to the technical field of strength tests, and relates to a large-load coordination loading device; the loading device comprises a loading actuating cylinder, a supporting column, a lever and a pull rod, wherein the loading end of the test piece is connected with the pull rod, the loading actuating cylinder and the supporting column are respectively fixed on a bearing wall, the loading actuating cylinder and the supporting column are respectively connected to two ends of the lever, and the pull rod is connected to the middle of the lever. The position of the pull rod is adjusted according to the load to be loaded, and the load to be loaded can be obtained. In the loading process, the loading of the required load value can be realized through the loading load of the loading actuating cylinder or the connecting position of the pull rod and the lever, the loading device is simple and convenient, and the loading device can be widely used for test pieces needing to load larger loads.
Description
Technical Field
The utility model belongs to the technical field of the strength test, a loading device is coordinated to big load is related to.
Background
At present, in a test requiring large load loading, the maximum loading point can reach more than 100 tons, but a common laboratory has no loading actuator cylinder with more than 100 tons, and at this time, two or more loading actuator cylinders are generally adopted to be combined in parallel to output the required load, but after two or more loading actuator cylinders are connected in parallel, the time steps of output force are inconsistent when the two or more loading actuator cylinders are loaded simultaneously, so that the imbalance of a lever connected with the loading actuator cylinders is caused, and the loading effect is influenced.
Disclosure of Invention
The utility model aims at: a large-load coordination loading device is designed to solve the technical problem that in the large-load loading process, when two or more loading actuating cylinders are loaded simultaneously, time steps of output force are inconsistent, and therefore a lever connected with the loading actuating cylinders is unbalanced.
For solving the technical problem, the technical proposal of the utility model is that:
a large load coordination loading device comprises a loading actuating cylinder 1, a supporting column 2, a lever 3 and a pull rod 4; the loading actuating cylinder 1 and the supporting column 2 are positioned at one side of the lever 3, one end of the loading actuating cylinder 1 is connected to the bearing wall, the other end of the loading actuating cylinder is connected to the lever 3, one end of the supporting column 2 is connected to the bearing wall, and the other end of the supporting column 2 is connected to the lever 3; one end of the pull rod 4 is connected to the other side of the lever 3, and the other end of the pull rod is connected with a test piece when in use.
The connecting position of the pull rod 4 and the lever 3 is adjustable.
The connecting position of the pull rod 4 and the lever 3 is between the fixing position of the loading actuating cylinder 1 and the lever 3 and the fixing position of the supporting column 2 and the lever 3.
The support column 2 is a steel column.
The technical effects of the utility model are that: apply the utility model discloses a load device is coordinated to big load on the test piece that needs the great concentrated load of loading, can effectually prevent the inconsistent problem of load time that two or more loading actuating cylinders loading arouse simultaneously to can design the size of load through adjusting the hookup location of pull rod and lever.

Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in fig. 1, which is a schematic structural diagram of the present invention, the large load coordination loading device of the present invention includes a loading actuator cylinder 1, a support pillar 2, a lever 3, and a pull rod 4; the loading actuating cylinder 1 and the supporting column 2 are positioned at one side of the lever 3, one end of the loading actuating cylinder 1 is connected to the bearing wall, the other end of the loading actuating cylinder is connected to the lever 3, one end of the supporting column 2 is connected to the bearing wall, and the other end of the supporting column 2 is connected to the lever 3; one end of the pull rod 4 is connected to the other side of the lever 3, the connecting position is between the fixing positions of the loading actuating cylinder 1 and the lever 3 and the fixing positions of the supporting column 2 and the lever 3, the connecting position is adjustable, and the other end of the pull rod is connected with a test piece when in use.
FIG. 2 is a schematic view of the load and distance of each structure of the present invention; the following description, with reference to the information labeled in fig. 2, illustrates the use of the present invention as follows: the output load of the pull rod loading actuating cylinder 1 is P1The distance between the connecting point of the loading cylinder 1 and the lever 3 and the connecting point of the pull rod 4 and the lever 3 is l1The distance between the connecting point of the support column 2 and the lever 3 and the connecting point of the pull rod 4 and the lever 3 is l2The load on the test piece at the tie rod is P. According to the lever principle, the load of the pull rod on the test piece can be obtainedTo the loading device, l1+l2Is constant, i.e. l1+l2Can be obtained asThe connecting position of the pull rod and the lever is adjusted to satisfy l2The value is obtained.
