Detailed Implementation
[0011] Reference Figures 1-4 The comprehensive testing and inspection device for asphalt pavement in highway engineering is characterized by comprising: a protective outer box 1 and movable rollers 4 respectively connected to the four corners of the lower surface of the protective outer box 1; a permeation device 2 is movably inserted at the middle of the left edge of the lower surface inside the protective outer box 1; a pressure testing instrument 3 is connected at the middle of the right side of the upper surface inside the protective outer box 1; sealing covers 5 are inserted alternately at the middle of the upper surface of the left and right sides of the protective outer box 1; a fixed handle 6 is connected at the middle of the front edge of the upper surface of the protective outer box 1; and a control screen 7 is connected at the middle of the upper surface of the protective outer box 1.
[0012] In use, the operator first holds the fixed handle 6 and pushes the protective outer box 1 while the movable roller 4 rolls on the ground. Then, the operator moves the protective outer box 1 to the appropriate position. Next, the operator operates the control screen 7 to lift the movable roller 4 so that the lower surface of the protective outer box 1 contacts the ground. This prevents the protective outer box 1 from moving during use. Then, the operator rotates the sealing cover 5 upward and inserts the sealing cover 5 into the protective outer box 1. Finally, the operator operates the control screen 7 again to operate the permeation equipment 2 and the pressure testing instrument 3 for testing.
[0013] The internal structure of the permeation device 2 and the pressure-resistant instrument 3 is the same as that of the permeation device and pressure-resistant instrument in the prior art. Furthermore, the connection between the permeation device 2 and the pressure-resistant instrument 3 and the control screen 7 is also prior art. The desired effect of this utility model can be achieved by using the existing connection method.
[0014] Furthermore, the protective outer casing 1 includes a casing 1-1, slots 1-2, slides 1-3, and adhesive strips 1-4. Slots 1-2 are staggered at the middle of the upper part of the left and right side surfaces of the casing 1-1. Slides 1-3 are symmetrically arranged at the middle of the front and rear surfaces inside each slot 1-2. Adhesive strips 1-4 are symmetrically connected at the middle of the left and right edges of the upper surface of the casing 1-1. The permeation device 2 and the pressure resistance instrument 3 are arranged on the lower surface inside the casing 1-1.
[0015] When in use, the staff holds the fixed handle 6 and pushes the box 1-1 to the appropriate position. During testing, the staff inserts the sealing cover 5 into the slot 1-2.
[0016] Furthermore, the movable roller 4 includes a rodless cylinder 4-1, side plates 4-2, support columns 4-3, and casters 4-4. The side plates 4-2 are symmetrically connected to the center of the upper and lower surfaces of the sliding column on the rodless cylinder 4-1. The support column 4-3 is connected to the middle of the outer surface of the main cylinder on the rodless cylinder 4-1. The casters 4-4 are rotatably connected to the center of the lower surface of the support column 4-3. The two side plates 4-2 are connected to the outer surface of the housing 1-1. The support column 4-3 is L-shaped.
[0017] When in use, the operator starts the rodless cylinder 4-1, causing the main cylinder on the rodless cylinder 4-1 to move upward on the sliding column. At the same time, the support column 4-3 drives the caster 4-4 to move upward. Finally, the caster 4-4 separates from the ground and the lower surface of the box 1-1 contacts the ground.
[0018] Furthermore, the sealing cover 5 includes a box cover 5-1, a buckle plate 5-2, a sliding plate 5-3, and a locking post 5-4. The buckle plate 5-2 is connected to the middle of the lower edge of the outer surface of the box cover 5-1. The sliding plate 5-3 is rotatably inserted into the middle of the inner surface of the box cover 5-1. The locking posts 5-4 are symmetrically connected to the middle of the inner edges of the front and rear surfaces of the sliding plate 5-3. The buckle plate 5-2 is L-shaped. The box cover 5-1 and the sliding plate 5-3 are inserted into the slot 1-2. The locking posts 5-4 are inserted into the slide groove 1-3. The box cover 5-1 and the sliding plate 5-3 are connected to each other by a rotating shaft.
[0019] In use, the operator holds the buckle plate 5-2 and rotates the cover plate 5-1 upwards. At the same time, the cover plate 5-1 rotates on the slide plate 5-3. Then, the operator pushes the cover plate 5-1 to insert the cover plate 5-1 and the slide plate 5-3 into the slot 1-2. Simultaneously, the locking post 5-4 slides in the slide groove 1-3. When the cover plate 5-1 is fully inserted into the slot 1-2, the buckle plate 5-2 is locked onto the outer surface of the box body 1-1. At the same time, the adhesive strip 1-4 is inserted into the buckle plate 5-2 and squeezes the adhesive strip 4-1. This increases the friction between the buckle plate 5-2 and the box body 1-1, thus preventing the cover plate 5-1 from slipping out during use.
[0020] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
