[0002] In recent years, with the development of engineering construction, the number of trenches has increased, such as cable troughs and water trenches in tunnels. In order to protect the normal use of the trench, it is often necessary to set a cover plate on top. The cover plates are divided into cast-in-place and prefabricated. Prefabricated cover plates occupy a dominant position due to their unique advantages. The construction site often uses manual paving of prefabricated cover plates, which requires a lot of manpower and has low efficiency. The prefabricated cover plates need to be transported multiple times, which not only wastes manpower and machinery costs, but also causes the cover plates to be damaged. Summary of the invention

[0027] See also Figure 1-2, is a prefabricated cover paving equipment, including a base and a box body, the base includes a top platform 5 matched with a slide rail structure 6, the top platform 5 is sequentially matched with a plurality of lifting devices and a middle platform 4 for supporting the lifting devices at the end away from the slide rail structure 6; the middle platform 4 is also matched with a plurality of support columns 2 at the end away from the lifting device, each support column 2 is provided with a universal wheel 1 at the end away from the middle platform 4, the lifting device is a jack 3, and each jack 3 is marked with a scale for recording the height of the lift. The box body is formed by matching and splicing an L-shaped steel channel 9 without a door and an L-shaped steel channel 10 with a door, and a soft connection 11 is matched at the splicing point. The soft connection 11 has a certain rigidity, and the soft connection 11 can be correspondingly extended and retracted when the slide rail slides; a slide rail structure 6 is also matched and installed between the base and the box body, and the box body is matched and installed on the base through the slide rail structure 6. The slide rail structure 6 includes a slide rail fixedly installed on the top platform 5, and at least two sliders are symmetrically installed in the slide rail, and the sliders are respectively connected to the bottom of the L-shaped steel channel 9 without a door and the L-shaped steel channel 10 with a door. The two parts are symmetrically matched and connected, and a scale is set on the slide rail. A brake device is also installed on each slider; a pushing section is also set on the end of the box body close to the base, and a discharge port is set at one end of the pushing section, and a piston head 12 is matched and installed in the pushing section at the other end. The piston head 12 is also matched and connected with a combined push rod at the end away from the discharge port. The shape and size of the piston head 12 match the prefabricated cover plate 7, and it is set as a hollow steel box body. The stroke of the piston head 12 matches the width size of a prefabricated cover plate 7. The combined push rod includes a piston head 12 A matched follower rod 13 is connected, and the end of the follower rod 13 away from the piston head 12 is also matched with an active rod 14 hinged; a discharge door is set on the L-shaped steel groove 10 with a door, and its setting position is higher than the pushing section. The height of the pushing section matches the thickness of the single prefabricated cover plate 7. A rubber ring 8 is also matched on the inner wall of the box body on the side close to the pushing section. The thickness of the rubber ring 8 gradually increases along the height direction extending toward the pushing section, thereby increasing the friction force so that the prefabricated cover plate 7 can fall slowly. Its specific size can be adjusted according to the on-site construction conditions.

[0028] In this embodiment, multiple boxes are prepared, which are transported to the construction site after being filled with prefabricated cover plates 7 in the curing room. When all the cover plates of a box are pushed out and paved, the connection between it and the slider is released and replaced with another box filled with prefabricated cover plates 7. At the same time, the empty boxes can be transported back to the curing room for recycling.

[0029] In this embodiment, when a large number of prefabricated panels are installed in the box and the height is large, there may be a risk of overturning of one side of the steel trough due to the force on the bottom alone. The setting of the soft connection 11 makes the two steel troughs have a certain rigidity in their lateral direction, thereby avoiding this risk.

[0030] When the present invention is in use, the base portion is placed in the groove 15, and then the box body equipped with the prefabricated cover plate 7 is fixedly connected to the slider, and the height of the jack 3 is adjusted so that the discharge port and the position of the prefabricated cover plate are matched. After adjusting to the appropriate position, the prefabricated cover plate 7 is laid by pushing the piston head 12. After the laying is completed, only the box body needs to be replaced.

[0031] In this embodiment, there are cases where the sizes of the grooves 15 are different. When the small groove 15 is switched to the large groove 15, it is only necessary to adjust the slider on the slide rail to drive the L-shaped steel grooves 9 without doors and the L-shaped steel grooves 10 with doors on both sides to move to both sides. When moving to both sides, due to the existence of the soft connection 11, the size of the box discharge port can be appropriately increased to make its width appropriate to meet the size of the groove 15.

[0032] In this embodiment, when the prefabricated cover plate 7 is installed into the box, lubricant can be applied to its contact surface or environmentally friendly round particles can be sprinkled on it to facilitate the falling and pushing out of the prefabricated cover plate 7.

[0033] The present invention replaces manual paving with mechanical paving, which effectively improves work efficiency. At the same time, manual paving involves the problem of multiple transportation of prefabricated cover plates 7. Paving with this equipment only requires transporting the prefabricated cover plates 7 from the curing room to the construction site once, reducing the possibility of damage to the prefabricated cover plates 7.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
