Description

Technical Field

[0001] This application relates to the technical field of prestressed concrete pipe pile production, and particularly to a feeding and forming device for prestressed concrete pipe pile molds. Background Art

[0002] At the present stage, during the production of prestressed concrete pipe piles, the corresponding steel skeletons are first placed in the pipe pile molds, and then the pipe pile molds are placed at the bottom of the feeding and forming device. After the feeding and forming device injects concrete into the pipe pile molds and rotates to compact it, the pipe pile molds are then transferred to the curing workshop for curing to make the corresponding prestressed concrete pipe piles. However, in the prior art, although the amount of concrete input into the pipe pile molds by the metering device each time is certain, there is a phenomenon of material leakage during the process of injecting concrete into the filling molds. Operators need to manually push the concrete scattered around the blanking table into the pipe pile molds, otherwise the prestressed concrete pipe piles will be defective due to insufficient concrete addition after forming. Summary of the Utility Model

[0003] In view of the above problems, the embodiments of this application provide a feeding and forming device for prestressed concrete pipe pile molds, which can ensure that the concrete falling in one time by the metering device can completely enter the pipe pile molds and reduce the labor intensity of workers.

[0004] According to one aspect of the embodiments of this application, a feeding and forming device for prestressed concrete pipe pile molds is provided. The feeding and forming device for prestressed concrete pipe pile molds includes a base, a fixture arranged on the top of the base, and a blanking table arranged on the top of the fixture. A through blanking port is arranged on the blanking table. A support frame is arranged on the outer periphery of the blanking table. A conical blanking groove is opened on the top of the blanking table. An annular baffle is fixed at the top edge of the blanking table. A lifting device is arranged on the top of the support frame. The lifting device is connected with a blanking funnel through a cross bar. The bottom projection of the blanking funnel is located at the blanking port. A cleaning brush is detachably arranged on the cross bar. The cleaning brush has a brush head, and the brush head extends to the blanking groove. A blowing pipe is arranged on one side of the cleaning brush on the cross bar. The top of the blowing pipe is communicated with an air pump through a hose. A blanking chute and a rotating extrusion rod are respectively arranged on the top of the blanking funnel. The bottom of the rotating extrusion rod has an extrusion head, and the outer diameter of the extrusion head is smaller than the aperture of the blanking port and the blanking funnel.

[0005] In some embodiments, the top of the annular baffle extends inward and contracts to form an annular ear plate. The connection between the annular ear plate and the annular baffle, and the connection between the annular baffle and the blanking groove are both smooth.

[0006] In some embodiments, the blowing pipe is connected to the cross bar through a fixing member. The fixing member includes two first fixing blocks that are symmetrically and fixedly arranged at the bottom of the cross bar. A rotating ring is fixedly arranged on the outer side of the blowing pipe. A rotating shaft is commonly connected to the two first fixing blocks. The rotating ring is sleeved on the rotating shaft. A second fixing block is commonly connected between the two first fixing blocks at the top of the rotating shaft. The second fixing block is connected to the blowing pipe through an elastic member.

[0007] In some embodiments, there are multiple cross bars, and the cleaning brush and the blowing pipe are arranged on at least two of the cross bars.

[0008] In some embodiments, a maintenance ladder is arranged on one side of the support frame.

[0009] In some embodiments, a first connecting rod is arranged at the bottom of the cross bar. One end of the bottom of the first connecting rod is a threaded end. A connecting cylinder is fixedly arranged at the top of the cleaning brush. The connecting cylinder is provided with internal threads, and the connecting cylinder is screwed onto the first connecting rod.

[0010] The beneficial effects in this application are as follows: In this application, by providing a feeding funnel, the feeding funnel can receive the concrete from the feeding chute and convey it to the feeding table. The feeding funnel can, to a certain extent, prevent the concrete from spreading outward, so that most of the concrete can directly enter the pipe pile mold through the feeding port. By providing a feeding groove on the feeding table and arranging a cleaning brush and a blowing pipe on the cross bar, when the feeding table rotates, the cleaning brush has a relative displacement with it. At this time, the cleaning brush can sweep the concrete remaining in the feeding groove to the feeding port. At the same time, the blowing pipe can blow air onto the top of the feeding table to blow the concrete into the feeding port. Thus, it can be ensured that the concrete falling in one time by the metering device can completely enter the pipe pile mold, and at the same time, the labor intensity of workers is reduced.

[0019] Specifically, please refer to Figures 1 to 3 , Figure 1 which is a schematic diagram of the overall cross-sectional structure of the prestressed concrete pipe pile mold feeding and forming device provided by the embodiment of the present application, Figure 2 is Figure 1 an enlarged view at A, Figure 3This is a schematic diagram of the local structure at the blanking funnel provided by the embodiments of the present application. The injection molding device 100 for prestressed concrete pipe pile molds includes a base 110, a fixture 120 arranged on the top of the base 110, and a blanking table 130 arranged on the top of the fixture 120. When the tank truck delivers the pipe pile mold onto the base 110, the fixture 120 will clamp the pipe pile mold. Subsequently, after the concrete is injected into the pipe pile mold, the rotating extrusion rod 190 will be inserted into the pipe pile mold. The rotating extrusion rod 190 and the base 110 will rotate in opposite directions respectively, and during the rotation process, the rotating extrusion rod 190 gradually withdraws from the pipe pile mold. Since both the base 110 and the fixture 120 are prior arts, their specific structures and working methods will not be elaborated here too much. A through blanking port 131 is arranged on the blanking table 130. When the pipe pile mold and the base 110 rotate, the blanking table 130 rotates together. When the weighing scale sprinkles the concrete onto the blanking table 130, the concrete will fall into the pipe pile mold below through the blanking port 131. At the same time, the rotating extrusion rod 190 also extends into the pipe pile mold from the blanking port 131. A support frame 140 is arranged on the outer periphery of the blanking table 130. A conical blanking groove 132 is opened at the top of the blanking table 130. An annular baffle 133 is fixed at the top edge of the blanking table 130. The annular baffle 133 moves and rotates with the blanking table 130. By setting the annular baffle 133, it is avoided that the concrete on the top of the blanking table 130 pours outward under the action of centrifugal force. A lifting device 150 is arranged on the top of the support frame 140. The lifting device 150 can be in various forms such as an electric telescopic rod or a cylinder. The lifting device 150 is used to drive the blanking funnel 170 and the cross bar 160 to lift. The lifting device 150 is connected with a blanking funnel 170 through the cross bar 160. The bottom projection of the blanking funnel 170 is located at the blanking port 131. The weighing scale pours a certain amount of concrete to the blanking funnel 170 through the blanking chute 180. After being limited by the blanking funnel 170, most of the concrete will be concentrated and fall into the blanking port 131, so that it can directly fall into the pipe pile mold. However, there will still be a part of the concrete remaining on the top of the blanking table 130 at the edge of the blanking port 131. A cleaning brush 161 is detachably arranged on the cross bar 160. The cleaning brush 161 has a brush head, and the brush head extends to the blanking groove 132. When the blanking table 130 rotates with the base 110 and the pipe pile mold, since the support frame 140 does not rotate, the cleaning brush 161 on the blanking funnel 170 and the cross bar 160 does not displace either. At this time, a relative displacement will occur between the cleaning brush 161 and the blanking table 130, so that the cleaning brush 161 can clean the top of the blanking groove 132 to sweep the concrete remaining on the top of the blanking table 130 into the blanking port 131.On one side of the cleaning brush 161 on the cross bar 160, there is an air blowing pipe 162. The top of the air blowing pipe 162 is connected to an air pump through a hose 163. The air pump can transport gas through the hose 163 to the air blowing pipe 162, and the air blowing pipe 162 blows the gas to the blanking chute 132, so as to blow the concrete on the top of the blanking table 130 into the blanking port 131. On the top of the blanking funnel 170, there are respectively a blanking chute 180 and a rotating extrusion rod 190. The bottom of the rotating extrusion rod 190 has an extrusion head 191. The blanking chute 180 and the rotating extrusion rod 190 are both prior arts. The blanking chute 180 is used to transport the concrete to the blanking funnel 170, and the rotating extrusion rod 190 is used to penetrate into the pipe pile mold to extrude and shape the concrete in the pipe pile mold, so as to form a prestressed concrete pipe pile with a hollow interior. The outer diameter of the extrusion head is smaller than the aperture at the blanking port 131 and the blanking funnel 170, which is convenient for the extrusion head to pass through the blanking funnel 170 and the blanking port 131 and extend into the pipe pile mold.

[0020] As can be seen from the above, in the embodiment of the present application, by setting the blanking funnel 170, the blanking funnel 170 can receive the concrete from the blanking chute 180 and transport it to the blanking table 130. The blanking funnel 170 can, to a certain extent, prevent the concrete from spreading outward, so that most of the concrete can directly enter the pipe pile mold through the blanking port 131. By setting the blanking chute 132 on the blanking table 130 and the cleaning brush 161 and the air blowing pipe 162 on the cross bar 160, when the blanking table 130 rotates, the cleaning brush 161 has a relative displacement with it. At this time, the cleaning brush 161 can sweep the concrete remaining in the blanking chute 132 to the blanking port 131. At the same time, the air blowing pipe 162 can blow air on the top of the blanking table 130 to blow the concrete into the blanking port 131. Thus, it can be ensured that the concrete discharged by the metering device at one time can completely enter the pipe pile mold, and at the same time, the labor intensity of workers is reduced.

[0021] In some embodiments, the top of the annular baffle 133 extends inward and contracts to form an annular ear plate 133a. The connection between the annular ear plate 133a and the annular baffle 133, and the connection between the annular baffle 133 and the blanking chute 132 are both smooth. In the embodiment of the present application, by setting the ear plate, it further prevents the concrete on the top of the blanking table 130 from pouring outward. At the same time, during the process of the air blowing pipe 162 blowing air, the concrete will not be blown out to the blanking table 130. The smooth connection helps the concrete to quickly fall into the blanking port 131 under the blowing of the air blowing pipe 162.

[0022] In some embodiments, the blowing pipe 162 is connected to the cross bar 160 through a fixing member 164. The fixing member 164 includes two symmetric first fixing blocks 164a fixedly arranged at the bottom of the cross bar 160. A rotating ring 162a is fixedly arranged on the outer side of the blowing pipe. A rotating shaft 164b is commonly connected to the two first fixing blocks 164a. The rotating ring 162a is sleeved on the rotating shaft 164b. A second fixing block 165 is commonly connected between the two first fixing blocks 164a at the top of the rotating shaft 164b. The second fixing block 165 is connected to the blowing pipe through an elastic member 166.

[0023] Since the annular ear plate 133a is provided in some embodiments, during the process that the lifting device 150 drives the blowing pipe 162 to rise or fall, the blowing pipe 162 will abut against the annular ear plate 133a, causing collision damage. In the embodiments of the present application, through the above arrangement, when the blowing pipe 162 abuts against the annular ear plate 133a, the lifting device 150 further drives the blowing pipe 162 to rise or fall. At this time, the elastic member 166 will be stretched or compressed, and synchronously the blowing pipe will rotate along the rotating ring 162a, so that the blowing pipe 162 can rise or fall under the drive of the lifting device 150. And after rising or falling is completed, under the action of the elastic member 166, the blowing pipe 162 will be reset again.

[0024] In some embodiments, there are multiple cross bars 160, and cleaning brushes 161 and blowing pipes 162 are arranged on at least two cross bars 160. In the embodiments of the present application, through the above arrangement, the cleaning and blowing efficiency can be effectively increased, and at the same time, the arrangement of multiple cross bars 160 can effectively ensure the stability of the blanking funnel 170 during the working process.

[0025] In some embodiments, a maintenance ladder 141 is arranged on one side of the support frame 140. In the embodiments of the present application, by arranging the maintenance ladder 141, it is convenient for the operator to perform maintenance.

[0026] In some embodiments, a first connecting rod 167 is arranged at the bottom of the cross bar 160. One end at the bottom of the first connecting rod 167 is a threaded end. A connecting cylinder 161a is fixedly arranged at the top of the cleaning brush 161. The connecting cylinder 161a is provided with an internal thread, and the connecting cylinder 161a is screwed onto the first connecting rod 167. In the embodiments of the present application, the cleaning brush 161 is detachably connected to the cross bar 160 through the connecting cylinder 161a. Thus, when the lifting device 150 drives the cross bar 160 to lift, the operator can conveniently and quickly disassemble and replace the cleaning brush 161.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered within the scope of the claims and the description of the present application.
