The surface of the instrument box is covered with an insulating protective layer. The top opening of the instrument box constitutes a box mouth for taking and placing test instruments. The platform is lowered by an insulating telescopic rod and then covered on the opening of the instrument box.

The insulating telescopic rod is composed of upper, middle and lower three-section bushings, the outer diameter of the three-section casing gradually decreases from bottom to top, and after the insulating telescopic rod is stretched out, it is equipped with a positioning pin or a lock in the radial direction. Tighten the bolts to fix the three-section casing.

The lifting test platform is provided with upper and lower layers, and the two-layer lifting test platform is correspondingly fixed between the upper section and the middle section of the insulating telescopic rod.

The area of the upper lifting test platform is smaller than that of the lower lifting test platform.

Handles for carts are fixedly connected to the top ends of two adjacent insulating telescopic rods.

The mobile frame includes a rectangular underframe, in which two parallel linear guide rails are fixed along the pulling direction of the instrument box, and the instrument box is connected with the two sets of guide grooves correspondingly arranged at the bottom Two linear guide rail guide fit.

The linear guide rail is composed of channel steel extending forward and backward and several guide wheels arranged between the channel walls on both sides of the channel steel at intervals.

The traveling wheels are universal wheels with brakes.

A handle is fixed on the outer wall of the instrument case along its pulling direction.

The multifunctional foldable test vehicle of the present invention can put the instruments and equipment to be used in the instrument box when in use, and use the mobile frame to facilitate the transportation of the instruments and equipment. Cover the mouth of the instrument box to protect the equipment during transportation. It can also be used as a working platform for placing instruments and equipment after being raised and fixed, which is convenient for testers to work. At the same time, the instrument box can be pulled out as a whole and used as an insulating stool for testing. It can be used by personnel, and its overall structure is simple and easy to use, which effectively reduces the labor intensity of testers, ensures the safety of testers and instruments and equipment, improves the efficiency of test work, and solves the problems existing in the prior art.

Detailed ways

The specific embodiment of the multifunctional foldable test vehicle of the present invention is shown in Fig. 1-Fig. 2. A test platform 4 with a vertical lift is installed. A horizontally drawn instrument box 3 is installed on the mobile frame 1 below the test platform 4 through horizontal guide rails. The surface of the instrument box 3 is provided with an insulating protective layer. The instrument box 3 The top opening of the test platform constitutes the opening of the test instrument, and the test platform 4 is lowered by the insulating telescopic rod 2 and then covered on the opening of the instrument box 3 . In this embodiment, the mobile frame 1 has a rectangular structure, and the traveling wheels installed at the bottom of the mobile frame 1 are four universal wheels with brakes installed at the four corners. The four corners of the mobile frame 1 of the rectangular structure are vertical Insulated telescopic rods 2 are fixed, and the structures of each insulated telescopic rod 2 are the same, which are composed of upper, middle and lower three-section bushings matched with sleeves. The outer diameters of the three-section sleeves gradually decrease from bottom to top, wherein The casing 20 is fixed on the mobile frame 1, the middle section casing 21 is set on the lower section casing 20, the upper section casing 22 is correspondingly set on the middle section casing 21, and the lower section casing 20 and the middle section casing 21 and between the middle casing 21 and the upper casing 22 are respectively locked and fixed by positioning pins or locking bolts (not shown in the figure) worn radially; the test platform 4 is provided with upper and lower layers. The two-layer test platform 4 is a rectangular structure, and there are upturned edges around the two-layer test platform 4 to prevent the equipment from slipping. The four corners of the two-layer test platform 4 are correspondingly fixed on four insulating telescopic rods. 2. On the middle section casing 21 and the upper section casing 22, the area of the upper test platform 4 is smaller than that of the lower test platform 4. When the four insulating telescopic rods 2 shrink synchronously and the two-layer test platform 4 is lowered, the area of the upper test platform 4 is lowered. The test platform 4 just falls in the test platform 4 of the lower floor, so that the folded height of the test vehicle of the present invention is minimized; The top end of the adjacent insulating telescopic rod 2 is fixedly connected with the handle 6 for the trolley; the mobile frame 1 of the rectangular structure includes a rectangular underframe in which two mutually Parallel linear guide rails, these two linear guide rails are composed of channel steel 11 extending forward and backward and a number of guide wheels 12 installed between the channel walls on both sides of the channel steel 11 at intervals, and two groups are arranged at the bottom of the instrument box 3 The guide groove 31 that cooperates with the corresponding linear guide rail guide, the linear guide rail composed of channel steel and guide wheels installed in the rectangular chassis can increase the carrying capacity of the mobile frame, and avoid the movement of the frame after the instrument box is full of equipment. At the same time, this linear guide rail structure is also convenient for the overall extraction and insertion of the instrument box, so that the test staff can use the instrument box as an insulating stool, which improves the comfort of the test staff during work and further reduces the labor of the test staff. strength. The multifunctional foldable test vehicle of the present invention has a simple overall structure and is easy to use, effectively reduces the labor intensity of test personnel, ensures the safety of test personnel and instruments and equipment, improves test work efficiency, and solves the problems existing in the prior art .
