[0002] The steel plate roadbed box is mainly composed of a frame body, which is composed of a longitudinal main reinforcement frame and a transverse frame. The surface of the frame body is sealed with a patterned anti-skid steel plate, and the reverse side is sealed with a flat steel plate, forming a box body as a whole. When laying the traditional roadbed box, it is mainly hoisted and laid by hoisting equipment;

[0003] In order to ensure the stability of the vehicle during travel, the ends of adjacent roadbed boxes need to be connected by connecting structures. If there is a certain error between adjacent roadbed boxes during lifting, the adjustment process is relatively cumbersome, which makes the traditional roadbed box have high requirements on the lifting accuracy of the lifting equipment. Therefore, a roadbed box that is easy to lay is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] See also Figure 1-5 The utility model provides an embodiment: a roadbed box that is easy to lay, including a first steel plate 3, main reinforcement frames 1 are welded on both sides below the first steel plate 3, transverse frames 2 are welded in front and behind the lower end of the first steel plate 3, second steel plates 13 are welded at the lower ends of the main reinforcement frame 1 and the transverse frame 2, and a plurality of I-shaped reinforcement ribs are arranged between the first steel plate 3 and the second steel plate 13;

[0025] Also includes:

[0026] Lifting grooves 8, which are arranged at the four corners of the upper end of the first steel plate 3;

[0027] The rebound storage groove 10 is arranged on the inner side of the lifting groove 8, and a locking plate 17 is arranged inside the rebound storage groove 10, and a caster groove 14 is arranged below the locking plate 17, and a universal seat 15 is arranged inside the caster groove 14. The upper end of the universal seat 15 extends to the upper end of the locking plate 17, and a positioning plate 11 is installed. Both sides of the positioning plate 11 are connected to the locking plate 17 by screws 12, and a caster 16 is installed at the lower end of the universal seat 15.

[0028] See also Figure 4 The locking plate 17 and the positioning plate 11 are connected by a spring 18. When the screw 12 on the positioning plate 11 is unlocked, the positioning plate 11 can rebound upward under the resetting action of the spring 18 due to the loss of the screw 12 limit, driving the caster 16 to be stored in the caster groove 14.

[0029] See also Figure 1 The inside of the lifting trough 8 is welded with tying rods 9, which are distributed at the four corners of the upper end of the roadbed box. The tying rods 9 inside can be connected to the hook of the lifting equipment through a four-point lifting method to ensure the stability of the lifting process.

[0030] See also Figure 1The upper surface of the first steel plate 3 is provided with anti-skid patterns 4, and the anti-skid patterns 4 are integrally formed with the first steel plate 3. The anti-skid patterns 4 can increase the friction between the wheel hub and the first steel plate 3 during the driving process of the vehicle.

[0031] See also Figure 1 A plug-in piece 5 is provided at the front end of the main reinforcement frame 1, and a slot 6 is provided at the rear end of the main reinforcement frame 1. Positioning through holes 7 are provided inside the plug-in piece 5 and the slot 6. After the roadbed box is arranged, the plug-in piece 5 at the front end of the adjacent roadbed box can be inserted into the slot 6 at the rear end of another roadbed box, and the plug-in piece 5 and the positioning through holes 7 in the slot 6 are connected by bolts to ensure the stability of the connection between the adjacent roadbed boxes and avoid the situation where the gap at the connection increases due to the uneven force on the roadbed box when the vehicle is moving.

[0032] Working principle: universal casters 16 are provided at the four corners of the lower end of the roadbed box, and rebound receiving grooves 10 are provided at the upper end of the roadbed box at positions corresponding to the casters 16. During transportation, a base 19 can be set in advance in the cargo hold of the transport vehicle, and then the roadbed boxes can be stacked on the base 19 in sequence by relying on lifting equipment. Four positioning grooves are provided in the base 19, which correspond to the positions of the casters 16 at the four corners of the lower end of the roadbed box, so as to realize the positioning of the lowest roadbed box and the base 19, while the positioning between adjacent roadbed boxes can be realized by the engagement of the lower casters 16 and the upper rebound receiving grooves 10, so as to ensure the stability of the transportation process and prevent the stacked roadbed sheets from shifting due to the bumps and shaking of the transport vehicle. During laying, the lifting equipment fixes the roadbed sheet through the lifting grooves 8 at the four corners of the upper end of the roadbed sheet, and relies on lifting to It moves to the laying site, and after the roadbed boxes are arranged at the placement sites in turn, the universal caster 16 structure arranged at the bottom of the roadbed box can facilitate fine-tuning of the roadbed box. The sliding action of the caster 16 is used to make the plug 5 at the front end of the adjacent roadbed box fit into the slot 6 at the rear end of another roadbed box, and the plug 5 is connected to the positioning through hole 7 in the slot 6 by bolts to ensure the stability of the connection between the adjacent roadbed boxes and avoid the situation where the gap at the connection increases due to the uneven force on the roadbed box when the vehicle is moving. After the roadbed boxes are connected, the screws 12 on the positioning plate 11 of the caster 16 are unlocked one by one. Due to the loss of the screw 12 limit, the positioning plate 11 can rebound upward under the resetting action of the spring 18, driving the caster 16 to be stored in the caster groove 14, so that the second steel plate 13 on the lower surface of the roadbed box is completely in contact with the ground.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
