Description

Technical Field

[0001] This invention relates to the technical field of precast components for construction, and in particular to a concrete placing machine for the bottom web reinforcement of a highway small box girder. Background Technology

[0002] In highway construction, prefabricated small box girders are often used. The steel reinforcement cage of the small box girder is welded in the factory and then the concrete is poured on the construction site.

[0003] Reference Figure 1 As shown, during factory welding, the base plate 61 and web plate 62 need to be welded together to form the frame reinforcement 6, then several frame reinforcements 6 are arranged in a longitudinal array, and finally all the frame reinforcements 6 are bundled and welded together.

[0004] However, in the existing technology, the frame reinforcement 6 is usually arranged manually by workers one by one; however, each small box girder has dozens or even hundreds of frame reinforcement 6. Thus, the labor intensity of arranging the frame reinforcement 6 manually by workers is high, the degree of automation is low, it is not conducive to mass production in the factory, and it reduces the production efficiency of highway small box girders. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides a concrete placing machine for the bottom web reinforcement of a highway small box girder, the purpose of which is to realize the automatic placement of the frame reinforcement and improve the production efficiency of the box girder.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0007] A concrete placing machine for the bottom web reinforcement of a small box girder in highways is provided, comprising: a circulating feeding mechanism for conveying the frame reinforcement in a fixed direction and guiding it to fall; a discharge port on the circulating feeding mechanism for the frame reinforcement to fall; a storage rack located below the circulating feeding mechanism for receiving the frame reinforcement; several storage slots on the storage rack for placing the frame reinforcement; and a differential speed mechanism for driving the circulating feeding mechanism and the storage rack to move relative to each other, thereby positioning the discharge port above different storage slots.

[0008] Furthermore, the circulating feeding mechanism includes: a conveyor chain; several hooks disposed on the conveyor chain for hanging frame reinforcement; at least two sprockets for tensioning the conveyor chain, with the central axis of the sprockets being horizontally positioned; and a first drive motor for driving one of the sprockets to rotate.

[0009] Furthermore, the differential mechanism includes: a traveling frame, on which the circulating feeding mechanism is mounted; a guide rail, on which the traveling frame is movably mounted, and a shelf is fixedly mounted on one side of the guide rail; and a second drive motor for driving the traveling frame to translate along the guide rail.

[0010] Furthermore, the fabric placing machine also includes a telescopic component located between the circulating feeding structure and the shelf, wherein the piston rod of the telescopic component can block / release the falling path of the frame reinforcement by telescopic movement.

[0011] Furthermore, the angle α between the piston rod and the horizontal direction is an obtuse angle.

[0012] Furthermore, the fabric placing machine also includes: a carrying rod, located at one end of the piston rod, for receiving the frame reinforcement; a sleeve and a mounting plate, wherein the main body of the telescopic component and the sleeve are fixedly mounted on the mounting plate, and the carrying rod is slidably mounted inside the sleeve.

[0013] Furthermore, the fabric placing machine also includes a guide ramp, which is provided on the shelf to guide the frame reinforcement to slide down.

[0014] The beneficial effects of this invention are as follows: By setting a circulating feeding mechanism, several frame reinforcement bars can be output regularly and continuously from the material drop outlet; by setting a differential speed mechanism to ensure that the material drop outlet is above different placement slots, the frame reinforcement bars output by the circulating feeding mechanism can be ensured to fall into the corresponding placement slots, and the frame reinforcement bars are arranged regularly in the placement rack to complete the placement operation of multiple frame reinforcement bars; by using this invention, the placement operation of frame reinforcement bars can be completed automatically, reducing manual labor and improving the automation level and manufacturing efficiency of box girder production.

Web plate. Detailed Implementation

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 2 and Figure 4 As shown, this embodiment of the invention provides a concrete placing machine for the bottom web reinforcement of a highway small box girder, including: a circulating feeding mechanism 1 for conveying the frame reinforcement 6 in a fixed direction and guiding the frame reinforcement 6 to fall; and a dropping port 2, which is opened on the circulating feeding mechanism 1 for the frame reinforcement 6 to fall.

[0024] Specifically, the circulating feeding mechanism 1 includes: a conveyor chain 11; a plurality of hooks 12, which are disposed on the conveyor chain 11 for hanging the frame reinforcement 6; at least two sprockets 13 for tensioning the conveyor chain 11, and the central axis of the sprockets 13 is horizontally arranged; and a first drive motor 14 for driving one of the sprockets 13 to rotate.

[0025] It is worth mentioning that multiple frame ribs 6 can be buffered on the circulating feeding mechanism 1 by using several hooks 12, and wait for output.

[0026] It is worth mentioning that two synchronously moving circulating feeding mechanisms 1 are provided, which are used to hang the two sides of the frame ribs 6 respectively, thereby improving the stability of the feeding action.

[0027] Understandably, in the initial state, the hook 12 is set vertically, and the first drive motor 14 drives the sprocket 13 to rotate, which in turn drives the conveyor chain 11 to move in a fixed direction. As the conveyor chain 11 drives the hook 12 past the sprocket 13, the hook 12 can rotate around the sprocket 13, thereby changing the angle between the hook 12 and the vertical direction, so as to guide the frame rib 6 to slide off the hook 12 and fall down from the discharge port 2. In this invention, by setting the circulating feeding mechanism 1, several frame ribs 6 can be regularly and continuously output from the discharge port 2.

[0028] In this invention, a shelf 3 is also provided, located below the circulating feeding mechanism 1, for receiving frame ribs 6; several storage slots 31 are provided on the shelf 3 for placing frame ribs 6; a differential mechanism is provided to drive the circulating feeding mechanism 1 and the shelf 3 to generate relative movement, so that the material drop port 2 is positioned above different storage slots 31 and falls into the storage slots 31 of the shelf 3; by providing a differential mechanism to ensure that the material drop port 2 is positioned above different storage slots 31, it is possible to ensure that the frame ribs 6 output by the circulating feeding mechanism 1 fall into the corresponding storage slots 31, and arrange the frame ribs 6 regularly within the shelf 3 to complete the material placement operation of multiple frame ribs 6.

[0029] By using this invention, the placement of the frame reinforcement 6 can be completed automatically, reducing manual labor and improving the automation level and manufacturing efficiency of box girder production.

[0030] Specifically, the differential mechanism includes: a traveling frame 41, on which the circulating feeding mechanism 1 is mounted; a guide rail 42, on which the traveling frame 41 is movably mounted, and a shelf 3 is fixedly mounted on one side of the guide rail 42; and a second drive motor 43, which drives the traveling frame 41 to translate along the guide rail 42.

[0031] Reference Figure 3 As shown, in this embodiment, both the shelf 3 and the guide rail 42 are fixedly installed. Several rollers are rotatably installed on the trolley frame 41. The rollers are rotatably mounted on the guide rail 42. The second drive motor 43 drives the rollers to rotate, which in turn drives the trolley frame 41 to move along the guide rail 42. This creates a differential speed between the shelf 3 and the circulating feeding mechanism 1, and the two move relative to each other, so as to align the discharge port with different storage slots 31.

[0032] Of course, the shelf 3 can also be movably set on the guide rail 42, and the trolley frame 41 can be fixedly set. By driving the shelf 3 to move along the guide rail 42, different storage slots 31 can also be placed below the material drop port 2. In this way, while the storage slot 31 receives the frame rib 6, the shelf 3 can also be sent to the downstream processing process.

[0033] Reference Figure 5 As shown, the fabric feeding machine also includes a telescopic component 5, located between the circulating feeding structure and the shelf 3. The piston rod 52 of the telescopic component 5 can block / release the falling path of the frame rib 6 by telescopic movement.

[0034] It is worth mentioning that when the piston rod 52 is in the extended state, it can block the falling path of the frame rib 6 and receive the frame rib 6 falling from the discharge port 2, thereby hanging the frame rib 6 on the piston rod 52; when the piston rod 52 is in the telescopic state, it can re-extract the frame rib 6 hanging on the piston rod 52 and let it fall towards the storage groove 31 again.

[0035] By setting the telescopic component 5, the falling frame rib 6 can be blocked. The frame rib 6 falls towards the shelf 3 in stages, which can reduce the time of the frame rib 6 falling at one time and play a buffering role for the frame rib 6. It can prevent the frame rib 6 and the shelf 31 from having too much impact, effectively prevent the frame rib 6 from being deformed by impact, and also prevent the frame rib 6 from popping out of the shelf 31.

[0036] It is worth mentioning that the telescopic component 5 can be made of cylinder.

[0037] Furthermore, the angle α between the piston rod 52 and the horizontal direction is an obtuse angle, ensuring that the frame rib 6 can be effectively hung on the piston rod 52.

[0038] Furthermore, the fabric placing machine also includes: a carrying rod 53, which is disposed at one end of the piston rod 52 and is used to support the frame reinforcement 6; a sleeve 54 and a mounting plate 55, wherein the main body 51 of the telescopic component 5 and the sleeve 54 are both fixedly disposed on the mounting plate 55, and the carrying rod 53 is slidably disposed inside the sleeve 54.

[0039] Specifically, the mounting plate 55 is fixedly mounted on the crane frame 41 by means of rods.

[0040] By setting up a support rod 53 to support the frame reinforcement 6, under the action of gravity, the frame reinforcement 6 can be guided to slide a certain distance on the inclined support rod 53 until the frame reinforcement 6 abuts against the sleeve 54, which can initially position the frame reinforcement 6 in the horizontal direction and ensure that the frame reinforcement 6 can fall smoothly into the storage groove 31.

[0041] Reference Figure 6 As shown, the fabric laying machine also includes: a guide ramp 32, which is provided on the shelf 3 to guide the frame rib 6 to slide down. The guide ramp 32 guides the frame rib 6 to slide down into the shelf 31, and precisely positions the frame rib 6 to ensure that the frame rib 6 can fall smoothly into the shelf 31.

[0042] Those skilled in the art will understand that although preferred embodiments of the invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention. Clearly, those skilled in the art can make various alterations and modifications to the invention without departing from its spirit and scope. Thus, if these modifications and modifications of the invention fall within the scope of the machine equivalents of the claims, the invention also intends to include these modifications and modifications.
