Description

Technical Field

[0001] The utility model relates to the technical field of mobile equipment for prefabricated box culvert parts, and more specifically, to a box culvert production device. Background Art

[0002] A box culvert refers to a culvert or pipe gallery whose tunnel body is constructed with reinforced concrete box-shaped pipe sections. The box culvert parts in the existing technology are all prefabricated box culvert parts made of reinforced concrete and then spliced and installed. There are no slots or lifting points on the surface of the prefabricated box culvert parts, and equipment is needed to complete the grabbing and moving of the box culvert parts. When using a box culvert, it is often necessary to combine multiple box culverts side by side for use, or to separate the parallel box culverts for use. When the box culvert is split and combined in parallel, a crane is needed to lift and install the box culvert, which often requires the use of a moving device to move and transport the box culvert. At present, the existing box culvert moving devices are all moved by steel cables in conjunction with hooks. The steel cables are wrapped around the box culvert, and the hooks hang the steel cables and move them horizontally along the tracks of the hooks. This method has a simple structure, and the prefabricated box culvert parts are easily damaged, which cannot meet the current requirements of safe and efficient construction. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a box culvert production device to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0008] Two positioning rollers in rotational contact with the outer walls on both sides of the box culvert;

[0009] A slider is fixed to the bottom of the rotating shaft of the positioning roller, which is slidingly connected to the "Π"-shaped base. A screw rod I is threaded on the slider, and the screw rod I has a bidirectional thread. One end of the screw rod I is rotatably connected to the vertical end of the "Π"-shaped base, and the other end is connected to motor one through a coupling; the motor and the vertical end on the other side of the "Π"-shaped base are fixed; a clamping mechanism is provided above the "Π"-shaped base, and the clamping mechanism includes a main beam and a secondary beam, and motor two is installed on the top of the main beam through a mounting frame, and the secondary beam is telescopically sleeved on one end of the main beam, and side clamps are fixed to the outer ends of the main beam and the secondary beams, and clamping plates for clamping the box culvert are installed on one side of the side clamps through a mounting seat, and hanging ears are welded on the tops of the clamps on both sides.

[0010] As a further improvement of this solution, a screw rod II is installed inside the main crossbeam through a bearing; a circular internal thread groove is opened inside the secondary crossbeam, one end of the screw rod II is located inside the secondary crossbeam, and the other end of the screw rod II is fixed with a bevel gear II through a flat key; the second output shaft of the motor is fixed with a bevel gear I through a flat key, and the bevel gear I is located inside the main crossbeam, and the bevel gear I and the bevel gear II are meshed with each other.

[0012] As a further improvement of this solution, the side splints are in an "L" shape.

[0013] As a further improvement of this solution, an anti-slip serrated pad is installed on the inner side of the clamping plate.

[0014] Compared with existing technologies, this new method offers the following advantages: The prefabricated box culvert is moved forward by conveyor rollers. When it reaches the predetermined position, positioning rollers on the sides prevent it from sliding or deviating. A lifting device on the top connects the lugs of the clamping mechanism, and the two side clamps of the clamping mechanism are brought together to clamp the prefabricated box culvert. The positioning rollers are then released, and the box culvert is moved to the designated position for assembly. This method is more efficient and safer than existing chain-binding methods.

Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0022] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] Example 1:

[0024] Refer to the attached Figure 1-Figure 4 A box culvert production device of this embodiment is used for the production and transportation of a box culvert 100, which includes a "Π"-shaped base 1, a conveying roller 4 that is in rotational contact with the middle of the bottom wall of the box culvert 100, and two positioning rollers 8 that are in rotational contact with the outer walls on both sides of the box culvert 100.

[0025] A slider 7 is fixed to the bottom of the rotating shaft of the positioning roller 8 and is slidingly connected to the "Π"-shaped base 1. A screw rod Ⅰ6 is threaded on the slider 7, and the screw rod Ⅰ6 has a bidirectional thread. One end of the screw rod Ⅰ6 is rotatably connected to the vertical end of the "Π"-shaped base 1, and the other end is connected to the motor 1 61 through a coupling; the motor 1 61 is fixed to the vertical end of the other side of the "Π"-shaped base 1; a clamping mechanism 2 is provided above the "Π"-shaped base 1, and the clamping mechanism 2 includes a main beam 21 and a secondary beam 22. A motor 23 is installed on the top of the main beam 21 through a mounting frame, and the secondary beam 22 is telescopically sleeved on one end of the main beam 21. The outer ends of the main beam 21 and the secondary beam 22 are fixed with side splints 3, and a clamping plate 31 for clamping the box culvert 100 is installed on one side of the side splint 3 through a mounting seat, and hooks 5 are welded on the top of the splints 3 on both sides.

[0026] The prefabricated box culvert is placed on conveyor rollers 4 and moved forward laterally. Once it reaches the preset position for assembly, motor 1 61 is activated, and the two sliders 7 move in the same direction via screw rod 1 6, driving positioning rollers 8 to secure the outer walls of the box culvert 100. After securing the position, the hanging ears 5 welded to the tops of the two side plywood plates 3 are connected to an external lifting device with rails. Motor 2 23 at the bottom of the main beam 21 is activated to adjust the spacing between the secondary beam 22 and the main beam 21. The side plywood plates 3 fixed at the outer ends of the main beam 21 and secondary beam 22 are brought closer together, and the clamping plates 31 clamp the box culvert 100. After clamping and securing, the positioning rollers 8 on the sliders 7 are loosened. The box culvert is then moved to the position for the next assembly step using the external lifting device with rails in conjunction with the hanging ears 5.

[0027] The telescopic adjustment structure and principle between the main crossbeam 21 and the secondary crossbeam 22 are as follows. Specifically, a screw rod II 210 is installed inside the main crossbeam 21 through a bearing; a circular internal thread groove 211 is opened inside the secondary crossbeam 22, one end of the screw rod II 210 is located inside the secondary crossbeam 22, and the other end of the screw rod II 210 is fixed with a bevel gear II 25 through a flat key; the output shaft of motor II 23 is fixed with a bevel gear I 24 through a flat key, and the bevel gear I 24 is located inside the main crossbeam 21, and the bevel gear I 24 and the bevel gear II 25 are meshed with each other.

[0028] During operation, the output shaft of motor 2 23 is fixed with bevel gear I 24 through a flat key, and bevel gear I 24 and bevel gear II 25 are meshed. After motor 23 is started, the power rotation is transmitted to screw rod II 210 through bevel gear I 24, and screw rod II 210 rotates in the thread groove 211 to realize the extension and retraction of auxiliary beam 22.

[0029] The side clamping plate 3 is L-shaped. The clamping plate 31 is fixed on the vertical end, and the horizontal end is respectively fixed to the main crossbeam 21 and the auxiliary crossbeam 22.

[0030] An anti-skid serrated pad 32 is installed inside the clamping plate 31. The anti-skid serrated pad 32 is installed to prevent the box culvert from slipping after being fixed.

[0031] The prefabricated box culvert components are moved forward by conveyor rollers to the desired position, where they are positioned by positioning rollers on the sides to prevent slippage. A lifting device on the top connects the lugs of the clamping mechanism, and the two side clamps of the clamping mechanism are brought together to clamp the prefabricated box culvert components. The positioning rollers are then released, allowing the box culvert to be moved to the designated position for assembly. This system is more efficient and safer than existing chain-binding systems.
