Description

Technical Field

[0001] The utility model relates to a testing technology, in particular to a trailer movable working platform. Background Art

[0002] In the trailer layout, the workbench is parallel to the central measuring bridge, on which relevant experimental equipment is installed and fixed. Manual operation is often required during installation, so a workbench is indispensable. The workbench can provide temporary storage for experimental equipment accessories and also provide a support platform for personnel activities, making it convenient for personnel to connect cables, fix experimental equipment, inspect and observe, etc.

[0003] The main function of the workbench is to facilitate the experimenters to install relevant experimental equipment on the trailer, to facilitate the experimenters to directly observe the equipment when the experimental equipment is running, and it is also an installation platform for cameras that record the operation process of the experimental equipment. It also has the function of personnel passage, etc.

[0004] However, the existing trailer workbench is mainly fixed in position relative to the central measuring bridge. Its advantage is good rigidity, but its disadvantage is also obvious. Due to the fixed position, its flexibility is poor. It often happens that when personnel install experimental equipment on the central measuring bridge, they are either too far away to operate and fix it, or too close (the gap is too small), making it inconvenient to observe. Utility Model Content

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0021] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense.

[0023] Example 1:

[0024] like Figure 1 As shown in Figure 2, a movable working platform on a trailer includes a workbench 3. Adjustment mechanisms are provided on both sides of the workbench 3. The adjustment mechanisms are arranged on a mounting seat 4. The mounting seat 4 is fixed to the main beam 1 of the trailer. The adjustment mechanisms drive the workbench 3 to move closer to or away from the central measuring bridge 2.

[0025] The trailer movable work platform of this embodiment drives the sliding seat 8 to move horizontally through the driving component, so that the workbench 3 can move closer to or away from the central measuring bridge 2, and cooperates with the locking component 12 to achieve rigid locking of the workbench 3 and the main beam 1. It has good rigidity, flexible adjustment, and easy use, which solves the shortcoming of insufficient flexibility of previous fixed work platforms.

[0026] like Figure 3 As shown, the adjustment mechanism includes a driving assembly arranged on the mounting seat 4, and horizontal guide rails 6 are horizontally arranged on the top and bottom of the mounting seat 4. A slider 7 is slidably fitted on the horizontal guide rail 6, and a sliding seat 8 is fixed to one side of the slider 7 relative to the horizontal guide rail 6. The sliding seat 8 is fixedly connected to the end of the workbench 3, and the driving assembly drives the sliding seat 8 to move along the horizontal guide rail 6.

[0027] The driving assembly includes a motor 11 and a screw 10. The motor 11 is fixed to one end of the mounting seat 4. The motor 11 drives the screw 10 to rotate. Bearings are provided at both ends of the screw 10. The bearings are arranged in bearing seats. The two bearing seats are respectively fixed to the two ends of the mounting seat 4. A nut 9 is threaded on the screw 10, and the nut 9 is fixed to the sliding seat 8.

[0028] Locking assemblies 12 are provided at both the top and bottom of the sliding seat 8. These assemblies include a cylinder and a pressure block. The cylinder is secured to the sliding seat 8 via a mounting plate, while the pressure block is secured to the end of the cylinder's piston rod facing the horizontal guide rail 6. When the position of the workbench 3 is adjusted, the locking assemblies 12 automatically lock. There are four locking mechanisms, which improve the overall rigidity of the workbench 3, making the movable workbench 3 roughly equivalent in rigidity to conventional fixed work platforms. This results in minimal vibration during trailer operation, naturally minimizing interference with the accuracy of data from experimental equipment.

[0029] A camera is fixed on the workbench 3; the camera is set to shoot the experimental process for repeated viewing later. With the adjustment mechanism, the whole or part of the experimental equipment on the central measuring bridge 2 can be shot to improve the shooting accuracy.

[0030] A ladder 5 is provided at one end of the workbench 3 ; the arrangement of the ladder 5 facilitates workers to move from the main beam 1 to the workbench 3 .

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
