Furthermore, reinforcing ribs are arranged on the inner side of the bracket main body along the length direction.

Furthermore, the reinforcing ribs are of arch, triangular supports or I-shaped steel structures.

Furthermore, the support hanging arm is positioned below the reinforcing rib.

Furthermore, each universal wheel group comprises 3 universal wheels.

Furthermore, the universal wheels are electric driving wheels.

Furthermore, weights are placed on the support hanging arms.

Furthermore, the support hanging arm is aligned with the calibration arm hanging arm.

Furthermore, the holding hook is of a semicircular annular structure.

Furthermore, the support hanging arm is of a strip-shaped structure.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses can be used to the equipment support that 72 inches heavy chassis dynamometer was markd for the warehousing and transportation of chassis dynamometer calibration arm, weight and the weight loading, the transport of demarcation in-process. The main interference problem of solving in the current device removal realizes reducing the manpower, practices thrift the purpose of calibration time. Avoid equipment to appear interfering the condition through adjustment strengthening rib position, share equipment weight through the design of a plurality of universal wheels, reduce the resistance of pushing away the process. The structure of the support is optimized, the number of universal wheels is increased, the weight transfer and support movement processes can be directly translated from the upper part of the calibration arm, and the support needs to be turned by 180 degrees in the original work and then bypasses from the empty space outside the drum area. Arrive and change original angle again behind the assigned position, because operating space limits, there is physical interference in support and demarcation arm and the on-the-spot facility of demarcation, and the work needs 4 to 5 people to accomplish in coordination more than, and the utility model discloses the during operation is by two people alright completion more than going on, manpower and the time cost that has significantly reduced.

Detailed Description

The technical solution in the embodiment of the present invention will be clearly and completely explained below with reference to the drawings in the embodiment of the present invention. It should be noted that, in the case of conflict, the embodiments and features of the embodiments of the present invention may be combined with each other, and the described embodiments are only a part of the embodiments of the present invention, and not all embodiments.

Referring to fig. 1-6 to illustrate the embodiment, an apparatus support for calibrating a chassis dynamometer includes a support main body, two clasps 1 are disposed on one side of the support main body, two support hanging arms 2 are disposed on the other side of the support main body, the two clasps 1 and the two support hanging arms 2 are disposed along a length direction of the support main body, two sets of universal wheel sets are disposed along the length direction of the bottom of the support main body, and each universal wheel set includes a plurality of universal wheels 4.

In this embodiment the clasp 1 is used for placing the calibration arm 6, the calibration arm hanging arm 5 is arranged at two ends of the calibration arm 6, the base 7 is arranged at the bottom of the calibration arm, and weights are placed on the support hanging arm 2.

In the chassis dynamometer calibration process, a calibration arm 6 and weights are required to be conveyed to a designated position where dynamometer calibration equipment is installed by using a support, after the calibration arm 6 is taken down from the holding hook 1, a calibration arm base 7 is fixed to a chassis dynamometer calibration station, the support is required to stretch across two sides of the calibration arm 6, and the support hanging arm 2 is aligned with the calibration arm hanging arm 5 in position, as shown in fig. 6. In the calibration process, calibration personnel successively carry calibration weights one by one from the support hanging arm 2 to the calibration hanging arm. In the process, the control computer can record the torque data one by one so as to finish the calibration of the torque sensor of the dynamometer. In the whole process, the weights are moved back and forth between the support hanging arm 2 and the calibration arm hanging arm 5 for 40 times to finish the one-side calibration of the dynamometer, then the support is pushed to convey the weights to the other end of the calibration arm 6 from two sides of the calibration arm 6 along the arrow direction, and the actions are repeated to finish the calibration. And repeatedly completing the calibration of the biaxial chassis dynamometer twice. The entire process was completed in about 2 hours.

The inner side of the support main body is provided with a reinforcing rib 3 along the length direction, so that the strength of the support main body structure is ensured. The reinforcing ribs 3 are arranged in the bracket main body in a middle-arranged mode, so that the interference of the bracket in the using process can be prevented.
