Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roadbed boxes, in particular to a combined and assembled roadbed box convenient to hoist and a use method thereof. BACKGROUND

[0002] A roadbed box is generally a box composed of two plates and a plurality of support plates between the two plates. The roadbed box is a facility used for paving roads. In a construction site, the ground cannot bear the weight of vehicles, so the roadbed box is generally used to pave roads for vehicle travel. The roadbed box is assembled to form a road surface and has the advantages of simple paving and easy recycling. The roadbed box is generally hoisted by a crane and transported to the paving point for paving. The crane generally hoists the roadbed box by a sling with a hook or a sling without a hook. When using the sling without the hook, the roadbed box is generally hung on the hook of the crane by passing the sling from below or through the middle of the roadbed box. In order to ensure the stability of the hoisted roadbed box, two slings are generally used to hoist the roadbed box at different positions to prevent the roadbed box from tilting. However, due to the lack of a fixing structure between the sling and the roadbed box, the roadbed box is easily tilted due to collision or other reasons during hoisting. The worker needs to adjust the position of the roadbed box according to the angle when paving the tilted roadbed box, which increases the trouble of the paving process.

[0003] The defects of the existing roadbed box are:

[0004] 1. Patent document CN105088918B discloses a spliced roadbed box, which comprises an upper cover plate (10), a lower cover plate (12) and a side plate (17), and a positioning mechanism and a connecting mechanism are arranged in the roadbed box (15). The spliced roadbed box of the present disclosure is provided with a positioning mechanism and a connecting mechanism, so that adjacent roadbed boxes can be accurately positioned and connected to form a rigid platform with large bearing capacity. In the roadbed box of the patent, if the sling without the hook is used to lift the roadbed box from below, the position of the sling needs to be adjusted many times to ensure that the sling can lift the roadbed box horizontally. Therefore, a combined and assembled roadbed box is needed to solve the problem of quickly limiting the sling lifting the roadbed box in the middle position of the roadbed box.

[0005] 2、Patent document CN104005314B discloses a variable cross-section mobile roadbed box, "including a flat plate and a wheel system. The lower surface of the flat plate is fixedly connected with a plurality of mutually parallel longitudinal rib plates. It also includes at least two support beams perpendicular to the longitudinal rib plates. The support beams are fixed below the longitudinal rib plates. It also includes at least two guide rails parallel to the longitudinal rib plates. The guide rails are fixed on the support beams. It also includes at least two moving beams perpendicular to the longitudinal rib plates. The moving beams are installed on the guide rails and can slide along the guide rails. It also includes at least four wheel systems. The wheel system is composed of a connecting plate, a latch, a support rod and a universal wheel," the roadbed box in this patent can be lifted by a sling and then lifted by a crane, but the roadbed box in this patent does not have a function of indicating the position of the sling and the hook of the crane above the roadbed box. The position of the hook of the crane needs to be roughly judged by the worker, so that the roadbed box lifted by the crane is easy to tilt. The worker needs to adjust the laying position of the roadbed box according to the degree of inclination of the roadbed box when laying the inclined roadbed box. The worker cannot intuitively understand the laying position of the roadbed box as when laying a horizontal roadbed box, which makes the laying relatively troublesome. Therefore, a combined and assembled roadbed box that can indicate the position of the hook of the crane and the end of the sling hanging on the hook on the roadbed box is needed to solve this problem.

[0006] 3、Patent document CN205024554U discloses a roadbed box, "including a box body (1) and a detachable cover plate (2), the upper surface of the box body (1) is recessed to form a groove (5) for laying a crane running track (4), and the top of the groove (5) is widened to form a boss (6) for supporting the cover plate (2). The roadbed box according to the utility model can not only lay a track, but also temporarily cover the track and be used as a rigid platform with bearing capacity, thereby improving the transfer efficiency of the crane," when the roadbed box in this patent is lifted by a sling, there is no structure to fix the relative position of the sling and the roadbed box, so that the relative position of the sling and the roadbed box can change when the roadbed box is collided during hoisting, causing the roadbed box to tilt. Therefore, a combined and assembled roadbed box that can increase the stability of the relative position of the roadbed box and the sling is needed to solve this problem.

[0007] 4、Patent document CN213681547U discloses a roadbed box, "including a box body, one end of the box body is fixedly connected with a filling box, the length direction of the filling box is perpendicular to the length direction of the box body, the side of the filling box away from the box body is open, a filling plate is arranged in the filling box, and one end of the filling plate is hinged to the opening of the filling box. The present application has the effects of reducing the gap between adjacent roadbed boxes when laying curved roadbeds, reducing the bumping phenomenon caused by the movement of engineering vehicles on the roadbed box, and improving the smoothness of the movement of engineering vehicles," the roadbed box in the patent is provided with a hanging handle capable of being hung by a hook, if the scraper handle is welded on the side of the roadbed box, it is not convenient to replace the hanging handle when the hanging handle is subjected to long-term stress or collision damage, therefore, a combined assembly type roadbed box capable of conveniently replacing the lifting assembly of the lifting belt is needed to solve the problem.

When using a sling with a hook to lift the roadbed box, the hook is directly hooked onto the two lifting frames (301) to lift the roadbed box. When using a sling without a hook to lift the roadbed box, the sling is passed through the inner sides of the two lifting frames (301) and then the two ends of the sling are connected to the hook of the crane. S2, then rotating the indicator rod (701) upwards to move the hook of the crane to the position of the indicator rod (701), so that the hook of the crane is located on the middle symmetry line of the first mounting plate (1), thereby enabling the crane to lift the roadbed box horizontally, thereby facilitating the workers to lay the roadbed box, avoiding the phenomenon of laying trouble caused by the roadbed box being not level, and improving the laying efficiency; S3. After the paving is completed, the indicator rod (701) is stored inside the installation groove (6), and then the lifting frame (301) is lowered to the inside of the first installation frame (2), thereby facilitating the vehicle to travel on the roadbed box.

5. The method for using the conveniently hoisted assembled roadbed box according to claim 4 is characterized in that: The S1 also includes the following steps: S11, before inserting the sling into the inner side of the lifting frame (301), insert the sling between the lifting frame (301) and the fourth mounting plate (5); The step S2 further includes the following steps: S21. Before the crane is lifted, the second threaded rod (501) is rotated to drive the pressing plate (502) to squeeze and fix the sling, thereby ensuring the stability of the sling, thereby preventing the roadbed box from turning over due to collision during the process of being moved by the crane, and ensuring the stability of the roadbed box when being lifted.
