Description

TECHNICAL FIELD

[0001] The application relates to the technical field of prefabricated part processing equipment, and discloses a surface roughening machine for concrete prefabricated parts. BACKGROUND

[0002] In the preparation process of a concrete prefabricated part, roughening treatment needs to be performed on the surface of the prefabricated part to improve the roughness of the surface, so that the prefabricated part can be better combined with cast-in-place concrete in subsequent construction. The existing roughening machine mainly comprises a support, a blade roller and a large number of roughening blades. The blade roller is installed at the top end of the support, and then the roughening blades are arranged at intervals on the blade roller. During the operation of the equipment, the surface of the prefabricated part moves relative to a row of roughening blades, and then the roughening blades are used to roughen the surface during the movement.

[0003] For example, the utility model patent with the application number 2021226051166 discloses an automatic roughening device for prefabricated parts, which comprises a support column and a roughening device. The roughening device is installed on the support column through a lifting device. A connecting rod is transversely installed at the lower end of the lifting device. A connecting plate is vertically installed on the connecting rod. A roughening disc is installed at the lower end of the connecting plate. The roughening discs are symmetrically arranged on the left and right sides. The two roughening discs are connected through a rotating shaft. A sweeper composed of a roller and bristles is also installed above the roughening device. The automatic roughening device adjusts the height of the roughening device through the lifting device, thereby reasonably adjusting the roughening depth. The sweeper can also clean the roughening discs, preventing concrete from adhering to the surface of the roughening discs and affecting the subsequent roughening process. However, the structure of the sweeper in the automatic roughening device is complex. When the sweeper is used to rotate and clean the roughening discs, the adhered concrete is thrown to the front and back sides, which requires manual cleaning of the fallen concrete, seriously increasing the workload of the workers. In view of the above shortcomings of the existing automatic roughening device, the application designs a surface roughening machine for concrete prefabricated parts that can effectively solve the above technical problems. SUMMARY

[0004] The application aims to provide a surface roughening machine for concrete prefabricated parts to solve the shortcomings of the existing automatic roughening device.

[0005] The application is achieved by the following technical solutions:

[0006] The utility model provides a surface roughening machine for concrete prefabricated part, including vertical side plate, first connecting rod and roughening blade, the top of two vertical side plates is rotatably connected with first connecting rod, and the vertical side plate is equipped with telescopic drive part which realizes the rotation of first connecting rod, and the both ends of first connecting rod are fixedly connected with connecting side plate, and the end of two connecting side plates is fixedly connected with second connecting rod, and a plurality of roughening blades are rotatably arranged on second connecting rod, and the second connecting rod on the both sides of roughening blade is equipped with knock swing arm, and the lower end of knock swing arm is connected with knock lever which acts on roughening blade, and the upper end is connected with connecting sleeve which is sleeved on second connecting rod, and the connecting sleeve and connecting side plate are equipped with elastic element which rotates and stores potential energy, and the connecting side plate is equipped with drive assembly which realizes the rotation of knock swing arm and instantaneous slip.

[0007] The surface roughening machine for concrete prefabricated part provided by the utility model realizes the rotation of first connecting rod by controlling the extension or shortening of telescopic drive part, then adjusts the height of second connecting rod through connecting side plate connected with first connecting rod, and thus the depth adjusting effect of roughening blade during roughening is achieved.

[0008] In addition, when the concrete impurities adhered to the roughening blade need to be cleaned after the surface roughening of the prefabricated part is completed, the drive assembly is started to make the knock swing arm rotate upward by a certain angle, and the elastic element is stored potential energy during the rotation, and the knock swing arm slips during the continuous rotation of the drive assembly, so that the knock lever rotates downward rapidly under the action of the elastic force and hits the row of roughening blades, and at this time, the roughening blades are rotatably connected to the second connecting rod, so that the concrete impurities adhered to the roughening blades are shaken off instantaneously under the action of inertia, which not only achieves the cleaning effect, but also concentrates the concrete impurities falling down, which is convenient for subsequent workers to clean.

[0009] As a specific setting of the above scheme, the drive assembly includes a drive motor arranged on the connecting side plate, an incomplete gear is arranged on the motor shaft of the drive motor, and a driven gear meshing with the incomplete gear is arranged on the connecting sleeve close to the drive motor. The above is a specific design form of the drive assembly, which drives the incomplete gear to rotate by using the drive motor, and then realizes the rotation and slipping process of the knock swing rod through the gear meshing.

[0010] As a specific setting of the above scheme, the top of two vertical side plates is provided with a bearing, the both ends of first connecting rod are rotatably connected with the bearing, and the end of first connecting rod extending out of the bearing is connected with a disc, and the movable end of telescopic drive part is connected with a convex shaft at a non-center position of the disc. The above controls the extension or shortening of telescopic drive part, and then makes the disc rotate, and then realizes the rotation of first connecting rod between the two bearings by using the rotation of the disc.

[0011] As a specific setting of the above scheme, the elastic member is a torsion spring, and the two ends of the torsion spring are connected with the connecting sleeve and the connecting side plate respectively. The torsion spring is a specific design form of the elastic member, and a coil spring, a spring or other elastic members can also be used for applicability design to replace the torsion spring.

[0013] As a further setting of the above scheme, the two vertical side plates are connected with arm plates, and the end of the arm plate is arranged on the path of upward rotation of the hair pulling blade, and a cleaning water tank is arranged between the ends of the two arm plates. When the hair pulling blade needs to be effectively cleaned, the hair pulling blade is turned upward by the action of the telescopic driving member, and the lower end of the hair pulling blade is immersed in the cleaning liquid for cleaning.

[0014] As a further setting of the above scheme, an ultrasonic vibration head is arranged on the cleaning water tank, an ultrasonic cleaning generator is fixedly installed on the arm plate, and the ultrasonic cleaning generator is connected with the ultrasonic vibration head through an electric wire.

The surface hair pulling machine not only effectively cleans the concrete impurities on the hair pulling blade, but also concentrates the shaken-off concrete impurities, which facilitates the cleaning of the subsequent workers. The structure of the entire hair pulling machine is simple and compact, and the hair pulling blade can be cleaned after each hair pulling process, thereby effectively ensuring the surface hair pulling effect of the subsequent concrete prefabricated parts.

[0018] 2、The surface wire drawing machine further is provided with a cleaning water tank, and the cleaning water tank is arranged on the path of the upward rotation of the wire drawing blade, when the wire drawing blade is not cleaned by the impact shaking action, the wire drawing blade can be directly rotated into the cleaning water tank, the surface of the wire drawing blade is quickly cleaned by the ultrasonic cleaning action in the cleaning water tank, and the subsequent use effect of the wire drawing blade is improved.

Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the present application.

[0028] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Figures 1-7 The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Embodiments

[0029] Embodiment 1 discloses a surface roughening machine for concrete prefabricated parts, referring to the accompanying drawings Figure 1 The main body of the surface roughening machine comprises two guide rails 1 arranged on the front and back sides of the prefabricated part mold, and each of the two guide rails 1 is provided with a vertical side plate 2. A roller 3 matched with the guide rail 1 is arranged on the lower surface of each vertical side plate 2. A traction device (not shown in the figure) for pulling the vertical side plate 2 left and right is arranged at the end of the guide rail 1. The traction device in the present embodiment is a prior art, which can realize the traction movement of the vertical side plate 2 by using a winding mechanism and a traction rope.

[0030] Referring to the accompanying drawings Figure 2 , the accompanying drawings Figure 3 , the accompanying drawings Figure 4 and the accompanying drawings Figure 5 , a bearing 4 is arranged at the upper end of each vertical side plate 2, and a first connecting rod 5 is rotatably arranged between the two bearings 4. A disc 6 is connected to the outer end of the first connecting rod 5 extending out of the bearing 4, and a protruding shaft is arranged at the non-center of the disc 6. An electric telescopic rod 7 is connected to the outer side of the vertical side plate 2, which can also be replaced by a gas cylinder, a hydraulic telescopic rod or other telescopic driving members. Then the top end of the electric telescopic rod 7 is connected to the protruding shaft on the disc 6. By controlling the extension or shortening of the electric telescopic rod 7, the first connecting rod 5 can be rotated between the two vertical side plates 2.

[0031] A connecting side plate 8 is fixedly connected to each end of the first connecting rod 5, and a second connecting rod 9 is fixedly connected to the lower end of the two connecting side plates 8. A row of roughening blade 10 is rotatably connected to the second connecting rod 9. The number and spacing of the roughening blade 10 are adjusted according to actual needs. When it is necessary to adjust the roughening depth of the roughening blade 10 on the surface of the concrete prefabricated part, the extension or shortening of the electric telescopic rod 7 is directly controlled to make the first connecting rod 5 rotate. Then the height of the connecting side plate 8 is adjusted in the process of the rotation of the first connecting rod 5, so as to achieve the effect of adjusting the roughening depth.

[0032] A knocking lever 12 is connected between the lower ends of the two knocking swing arms 11. A connecting sleeve 13 is arranged on the second connecting rod 9 at the top end of each knocking swing arm 11, and one of the connecting sleeves 13 is arranged in a concentric manner on the side surface of the pulling blade 10 and is provided with a driven gear 14. A resilient member 15 capable of storing potential energy is arranged between the connecting sleeve 13 and the lower end of the connecting side plate 8. In the specific design of the embodiment, the resilient member 15 is a torsion spring, and the two ends of the torsion spring are connected to the connecting sleeve 13 and the connecting side plate 8, respectively.

[0033] Finally, a driving motor 16 is fixedly arranged on the connecting side plate 8 on the side provided with the driven gear 14. The driving motor 16 is preferably a large-torque low-speed motor. An incomplete gear 17 is connected to the motor shaft of the driving motor 16, and the tooth surface of the incomplete gear 17 is arranged in meshing engagement with the driven gear 14.

[0034] When the lower end of the pulling blade 10 is found to be stuck with concrete slurry or other sundries after the surface pulling machine completes the pulling of the concrete prefabricated part, the driving motor 16 is started through the control panel of the surface pulling machine, so that the driving motor 16 rotates one circle. During the rotation of the driving motor 16, the knocking swing arm 11 is rotated upward through the meshing engagement between the incomplete gear 17 and the driven gear 14, and the resilient member 15 is stored with potential energy during the rotation. When the incomplete gear 17 is rotated to be disengaged from the driven gear 14, the knocking swing arm 11 is instantaneously rotated downward due to the action of the resilient member 15, and then the knocking lever 12 hits the row of pulling blades 10. Since the pulling blade 10 is rotationally connected to the second connecting rod 9, the adhered concrete slurry is shaken off due to the inertia action when the pulling blade 10 is hit, and the concrete slurry shaken off from the pulling blade 10 directly and neatly falls on the ground, which is convenient for subsequent cleaning. EMBODIMENT

[0035] Embodiment 2 discloses a surface pulling machine for concrete prefabricated parts, which is improved on the basis of the technical scheme in Embodiment 1.

[0036] The same parts of Embodiment 2 as Embodiment 1 are not described again, and the different parts are described with reference to the accompanying drawings of Embodiment 2 and the accompanying drawings of Embodiment 1. Figure 6 and the accompanying drawings of Embodiment 1. Figure 7 In Embodiment 2, the upper ends of the two vertical side plates 2 are connected with an arm plate 18, and the end of the arm plate 18 is arranged on the path of upward rotation of the pulling blade 10. A cleaning water tank 19 is fixedly connected between the two arm plates 18, and a guide knife opening 191 is formed in the inner side surface of the cleaning water tank 19 close to the pulling blade 10. A drain pipe 20 is arranged on the lower surface of the cleaning water tank 19, and the drain pipe 20 is provided with a control valve.

[0037] In addition, an ultrasonic cleaning generator 21 is fixedly installed on one of the arm plates 18, and a plurality of ultrasonic vibration heads 22 are arranged at intervals on the bottom wall of the cleaning tank 19 and connected to the ultrasonic cleaning generator 21 through wires.

[0038] After the surface roughening machine disclosed in Embodiment 2 completes roughening of the concrete prefabricated part, the control panel on the surface roughening machine is used to start the driving motor 16, so that the driving motor 16 rotates one circle. During the rotation of the driving motor 16, the knocking swing arm 11 is rotated upward by the meshing action between the incomplete gear 17 and the driven gear 14, and is stored by the elastic member 15 during the rotation. When the incomplete gear 17 is rotated to be disengaged from the driven gear 14, the knocking swing arm 11 can be instantaneously rotated downward quickly due to the action of the elastic member 15, and the knocking rod 12 hits the row of roughening blades 10. Since the roughening blades 10 are rotationally connected to the second connecting rod 9, the attached concrete slurry is shaken off due to the inertia action when the roughening blades 10 are hit.

[0039] When it is found that the surface of the roughening blade 10 still has impurities that are difficult to remove, the electric telescopic rod 7 is controlled to extend the piston rod, and the first connecting rod 5 is rotated and the end of the connecting side plate 8 is rotated upward under the action of the electric telescopic rod 7, at this time, the row of roughening blades 10 arranged on the second connecting rod 9 is close to the inner side of the cleaning tank 19, and the roughening blades 10 are guided into the cleaning tank 19 through the guide blade opening 191 during the continuous rotation of the connecting side plate 8, so that the lower end of the roughening blade 10 is immersed in the cleaning liquid. Then, the ultrasonic cleaning generator 21 is started, and the impurities attached to the roughening blade 10 can be quickly cleaned by the action of the ultrasonic vibration head 22.

[0040] Finally, when the cleaning liquid in the cleaning tank 19 needs to be replaced, the control valve on the drain pipe 20 is opened to drain the cleaning liquid, and then the control valve is closed and new cleaning liquid is added.

[0041] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
