Description

  The present invention is a vehicle collision test apparatus in which a vehicle is mounted on a test carriage, fixed, and the test carriage is easily replaced when the test carriage is slid along a guide rail to perform a vehicle crash test. The present invention relates to a vehicle collision test apparatus, a switching carriage apparatus, and a lifting rack apparatus that can be used.

Conventionally, various types of vehicle collision test apparatuses have been proposed.
For example, there is a vehicle that performs a destructive test of a test vehicle by directly pulling the test vehicle with a traction device and causing it to collide.
In this case, the test vehicle to be tested can be replaced simply by replacing the traction hook or the like with another test vehicle, and the test vehicle replacement operation is simple.

In addition, as a vehicle collision test device, in order to test the operation status of safety devices in the vehicle, the vehicle is mounted on and fixed to the test carriage, and the test carriage is slid along the guide rail and tested. There are those that perform an operation test of a safety device or the like in a vehicle without damaging the vehicle by applying an impact on a trolley.
In this case, rather than destroying the vehicle, the operation test of safety devices such as seat belts and airbags in the vehicle is performed. In order to perform the collision test again, various measuring devices, test devices, etc. Needs to be mounted and re-installed in the vehicle or on a test carriage outside the vehicle, and preparation takes a lot of time.

As a test apparatus for sliding the test carriage along the guide rail, there is one in which the guide rail and the guide rail fixing base are protruded and placed on the floor of the test site.
In this case, it is relatively easy to replace a vehicle in which various measuring devices, test devices, and the like are mounted and installed in the vehicle.
That is, a part of the guide rail and the guide rail fixing base can be divided and made movable, and a test carriage and a vehicle are mounted and fixed on the spare movable guide rail and the guide rail fixing base, and various measuring devices, If a device incorporating a test device is prepared, it can be easily replaced by simply moving it on the same test floor.
However, if the guide rail and the guide rail fixing base are protruded and placed on the floor of the test site, the mounting position of the specimen such as a vehicle is high during the collision test, making it difficult to prepare for measurement. In addition, since the guide rail fixing base protrudes, it is difficult to come and go within the test site.

Furthermore, in order to lower the mounting position of the test specimen such as a vehicle and facilitate measurement preparation, a recess is provided on the floor of the test site and a guide rail is disposed in the recess, and the level of the guide rail and the floor of the test site is the same. There is something that was made.
In this case, when exchanging the spare test carriage, the guide rail on which the vehicle is mounted, and the guide rail fixing base, a crane or the like is arranged, and the spare test carriage is used by using the crane in the recess of the floor of the test site. There is a problem that it is necessary to carry out and carry in the vehicle.
On the other hand, when the concave part of the floor of the test site is enlarged and a spare test carriage is arranged in the concave part, the work area of the test floor becomes narrow and difficult to share, and movement of the spare test carriage is restricted. There is a problem that.

  The present invention has been proposed in order to solve the above-described problems. The test carriage is slid along the guide rail, and an impact is applied to the test carriage to operate the safety device in the vehicle. In the vehicle collision test system for testing, the common area of the work area on the floor of the test site can be widened, and the test carriage, the guide rail on which the vehicle is mounted, and the guide rail fixing base can be moved freely within the test site. It is an object of the present invention to provide a vehicle collision test device, a switching cart device, and a lifting platform device that can be used.
