Description

Technical Field

[0001] The utility model relates to the technical field of precast pile production, in particular to a positioning and conveying device for cleaning a prestressed end face flange of a precast pile. Background Art

[0002] In the production process of precast piles, the cage reinforcement (i.e., steel bar skeleton) is first made, and then the cage reinforcement is loaded into a mold, and cement products are poured into it to finally form a precast pile. Usually, the cage reinforcement includes a main reinforcement cage, a head plate and end plate assembly fixed at one end of the main reinforcement cage, and a tail plate and end plate assembly fixed at the other end of the main reinforcement cage. The head plate and end plate assembly includes an end plate and a head plate flange fastened by several bolts, and a hoop riveted to the outer periphery of the end plate. The tail plate and end plate assembly includes an end plate and a tail plate flange fastened by several bolts, and a hoop riveted to the outer periphery of the end plate. Both the head plate flange and the tail plate flange are prestressed end face flanges.

[0003] At present, in the production of automated cage reinforcement production lines, prestressed end flanges (i.e., head plate flanges and tail plate flanges) are molded together with the cage reinforcement. When the mold is removed, the prestressed end flanges are removed from both ends of the precast pile and then flow into the next round of automated cage reinforcement production. However, a layer of concrete will adhere to the surface of the prestressed end flange after demolding. If the prestressed end flange flows directly into the next round of automated cage reinforcement production, a large amount of concrete residue will accumulate on the automated cage reinforcement production line equipment, increasing the equipment failure rate and affecting production efficiency and quality. Therefore, before the prestressed end flange is removed and flows into the next round of production, the concrete on the surface of the prestressed end flange needs to be cleaned.

[0004] In the prior art, the cleaning of prestressed end face flanges is done by workers on the ground. Workers need to carry and flip the prestressed end face flanges. The weight of the prestressed end face flanges used in the automated cage reinforcement production line is 15 to 62 kg. Workers also need to use shovels to knock and scrape them to clean them. This method has low cleaning efficiency, high labor costs, excessive physical exertion, and certain risks during the handling process. The knocking of the shovel will cause knocking pits on the surface of the prestressed end face flange, reducing the service life of the prestressed end face flange. Utility Model Content

[0120] The utility model provides a positioning and conveying device for cleaning the prestressed end face flange of a prefabricated pile, which is used for conveying, positioning and clamping the prestressed end face flange. The prestressed end face flange includes Figure 1 The head plate flange 101 shown, and Figure 2 The tail plate flange 102 shown, the head plate flange 101 and the tail plate flange 102 are all provided with a circle of through holes for realizing the detachable connection between the head plate flange 101 and the end plate, and the detachable connection between the tail plate flange 102 and the end plate. At the same time, a blocking plate 103 is fixed in the middle of the head plate flange 101, but a through flange hole 104 is provided in the middle of the tail plate flange 102. In addition, for the convenience of description, the conveying direction of the prestressed end face flange conveyed by the positioning conveying device is defined as the front direction.

[0121] like Figures 3 to 5As shown, the positioning and conveying device provided by the utility model includes a frame 20, a plurality of positioning and conveying rollers 30 rotatably mounted on the frame 20, and a positioning and clamping assembly 40 and a positioning and stopping assembly 50 mounted on the frame 20. Among them, the plurality of positioning and conveying rollers 30 are spaced apart from each other, and each positioning and conveying roller 30 extends straightly from left to right, and the prestressed end face flange thereon is conveyed forward by the rotation of the positioning and conveying roller 30. The positioning and clamping assembly 40 and the positioning and stopping assembly 50 are successively distributed along the conveying direction of the prestressed end face flange, that is, the positioning and clamping assembly 40 is distributed on the rear side of the positioning and stopping assembly 50. The positioning clamping assembly 40 includes a clamping drive source 41 and a pair of clamping jaws 42 that can be opened and closed. The pair of clamping jaws 42 are symmetrically distributed on the upper side of the positioning conveying roller 30 in a direction perpendicular to the conveying direction of the prestressed end face flange. The clamping drive source 41 is connected to the pair of clamping jaws 42 in a transmission connection to drive the pair of clamping jaws 42 to move toward or in the opposite direction, and accordingly realize the opening or closing of the pair of clamping jaws 42. The positioning stop assembly 50 includes a positioning stop drive source 51 and a flange stop component 52 that can be raised or lowered. The positioning stop drive source 51 is connected to the flange stop component 52 in a transmission connection, and the flange stop component 52 can be raised or lowered and arranged in the gap between two adjacent positioning conveying rollers 30.

[0122] The positioning and conveying device involved in the present application is applied to the automatic cleaning production line of the prestressed end face flange, and a cleaning device is arranged directly above it; in the front-to-back direction, the position where the positioning and clamping assembly 40 is located is also the cleaning station of the prestressed end face flange. Figure 3 As shown, the flange stop member 52 is in an ascending state, the flange stop member 52 is higher than the positioning conveying roller 30, and the pair of clamping jaws 42 are in an open state. Figure 3 As shown, the prestressed end face flange to be cleaned is conveyed to the rear end of the positioning conveying device, and the positioning conveying device conveys the prestressed end face flange to be cleaned forward by rotating the positioning conveying roller 30; when the prestressed end face flange to be cleaned is conveyed forward to the positioning stop assembly 50, it is stopped by the raised flange stop component 52; then, the clamping drive source 41 is actuated to drive a pair of clamping jaws 42 to move toward each other, thereby clamping the prestressed end face flange to be cleaned, as shown in FIG. Figure 4 As shown, the prestressed end face flange is reliably positioned and maintained at the cleaning station. Then, the positioning stop driving source 51 is activated to drive the flange stop component 52 to descend; the cleaning device above the positioning conveying device can automatically clean the prestressed end face flange at the cleaning station. After the cleaning is completed, the clamping driving source 41 is reset to drive a pair of clamping jaws 42 to move in the opposite direction to release the cleaned prestressed end face flange; the positioning conveying roller 30 continues to convey the cleaned prestressed end face flange forward.

[0123] Therefore, the positioning and conveying device involved in the present application can not only convey the prestressed end face flange forward, but also clamp the prestressed end face flange, and reliably fix the prestressed end face flange to be cleaned at the cleaning station, so as to facilitate the subsequent automatic cleaning operation of the prestressed end face flange, thereby saving labor costs, improving cleaning efficiency and quality, and avoiding pits on the surface of the prestressed end face flange caused by hitting with a shovel.

[0124] Furthermore, if Figures 5 to 7 As shown, the frame 20 is a frame structure welded by multiple columns and beams. There are seven positioning conveying rollers 30, and seven pairs of bearing seats 23 are fixed on the frame 20 and are evenly spaced in front and back. Two bearing seats 23 in each pair of bearing seats 23 are opposite to each other, and the left and right ends of each positioning conveying roller 30 are rotatably supported in a pair of bearing seats 23, respectively, so that the seven positioning conveying rollers 30 can be rotatably installed in the frame 20. In addition, an avoidance recess 31 is provided on the middle positioning conveying roller 30 to avoid the scraper in the cleaning device.

[0125] Preferably, if Figure 4 and Figure 5 As shown, a foot support assembly 24 is installed at the lower end of each column of the frame 20, and the foot support assembly 24 includes a foot plate 241 fixed to the ground by foot bolts, a column plate 242 fixed to the lower end of the column, an adjustment screw 243 inserted through the foot plate 241 and the column plate 242, and an adjustment nut 244 threadedly engaged with the outer periphery of the adjustment screw 243, and the adjustment screw 243 abuts against the upper and lower sides of the column plate 242. By adjusting the upper and lower positions of the adjustment nut 244 on the adjustment screw 243, the height of the foot support assembly 24 can be adjusted, and then the height and levelness of the frame 20 as a whole can be adjusted, thereby adjusting the height and levelness of the positioning conveying device as a whole.

[0126] Furthermore, in the positioning conveying device involved in the present application, a conveying drive motor can be separately configured, and the conveying drive motor drives several positioning conveying rollers 30 to rotate through a sprocket chain mechanism. Alternatively, the positioning conveying device does not separately configure a conveying drive motor, and several positioning conveying rollers 30 are connected to rollers in other conveying equipment on the automatic cleaning production line through a sprocket chain mechanism, thereby reducing equipment costs. In this embodiment, the positioning conveying device does not separately configure a conveying drive motor, and one of the positioning conveying rollers 30 in the positioning conveying device is connected to rollers in other conveying equipment on the automatic cleaning production line through a sprocket chain mechanism, and several positioning conveying rollers 30 are also connected to each other through a sprocket chain mechanism to achieve power transmission. At the same time, if Figure 6 As shown, a roller protection cover 25 is fixed to the upper end of the frame 20 to cover the sprocket chain mechanism and the bearing seat 23 to prevent the sprocket chain mechanism and the bearing seat 23 from being contaminated by concrete residues.

[0127] Preferably, if Figure 4 As shown, the positioning conveying device is fixedly provided with two front and rear guide units above the frame 20, each guide unit includes a pair of guide components symmetrically arranged on the left and right, each guide component includes a guide mounting plate 26 fixed to the frame 20, and a guide rod 27 fixed to the inner end side of the guide mounting plate 26, the guide mounting plate 26 is preferably arranged on the top surface of the roller protection cover 25, and the guide rod 27 extends forward and backward and is distributed on the upper side of the positioning conveying roller 30. Through the guide rod 27, the prestressed end face flange can be guided to the center position of the positioning conveying device to prevent the prestressed end face flange from excessive deviation.

[0128] Furthermore, if Figures 5 to 7 As shown, the positioning and conveying device also includes a slag collecting box 21 fixed to the frame 20, and the slag collecting box 21 has a slag collecting trough distributed under several positioning and conveying rollers 30. The slag collecting box 21 is provided with a slag discharge port, and the slag discharge port is communicated with the slag collecting trough. The slag collecting box 21 is provided with an openable and closable material port baffle 22 at the slag discharge port. When the cleaning device cleans the prestressed end face flange, the cleaned concrete residue falls into the slag collecting trough through the gap between two adjacent positioning and conveying rollers 30 to prevent the concrete residue from leaking. When the slag collecting trough needs to be discharged, the material port baffle 22 can be opened. Preferably, the upper end of the material port baffle 22 is hinged to the slag collecting box 21 through a hinge, and two sets of locking components distributed on the front and rear sides of the material port baffle 22 are fixed on the end surface of the slag collecting box 21, and each set of locking components includes a fixed buckle 28 fixed to the slag collecting box 21, and a locking plate 29 rotatably mounted on the material port baffle 22 through a hinge. When the locking plate 29 is rotated downward to a horizontal state, the locking plate 29 is clamped in the fixed buckle 28, and the material port baffle 22 is in a closed state; when the locking plate 29 is rotated upward to a vertical state, the locking plate 29 is disengaged from the fixed buckle 28, and the material port baffle 22 can be rotated upward to open.

[0129] Furthermore, if Figure 3 and Figure 4 As shown, in the front-to-back direction, the positioning clamping assembly 40 is installed at the middle position of the frame 20. The structure of the positioning clamping assembly 40 is preferably as follows: Figures 8 to 10As shown, the positioning clamping assembly 40 also includes a pair of clamping fixing seats 43 fixed to the frame 20 and facing each other left and right, two clamping guide rods 44 fixed between the pair of clamping fixing seats 43, a pair of clamping jaw mounting seats 45 mounted on the clamping guide rods 44 and movable left and right, and a connecting rod unit connected between the pair of clamping jaw mounting seats 45; the clamping driving source 41 is a cylinder, the piston rod of the cylinder is connected to the right clamping jaw mounting seat 45 of the pair of clamping jaw mounting seats 45, and a pair of clamping jaws 42 are respectively fixed on the pair of clamping jaw mounting seats 45. When the cylinder piston rod of the clamping driving source 41 extends to the right, it directly drives the right clamping jaw mounting seat 45 to move right, and at the same time, the right clamping jaw mounting seat 45 drives the left clamping jaw mounting seat 45 to move left through the connecting rod unit, thereby driving the pair of clamping jaws 42 to move in the opposite direction, thereby loosening the prestressed end face flange. On the contrary, when the cylinder piston rod of the clamping drive source 41 retracts to the left, it directly drives the right clamping jaw mounting seat 45 to move left. At the same time, the right clamping jaw mounting seat 45 drives the left clamping jaw mounting seat 45 to move right through the connecting rod unit, thereby driving a pair of clamping jaws 42 to move toward each other, thereby clamping the prestressed end face flange.

[0130] Preferably, if Figure 8 As shown, a clamping limit seat 410 is fixed on the inner end surface of each clamping fixed seat 43 facing the clamping jaw mounting seat 45, and a buffer pad 411 is fixed on the inner end of the clamping limit seat 410. When the clamping driving source 41 drives a pair of clamping jaws 42 to release the prestressed end face flange through a pair of clamping jaw mounting seats 45, the clamping jaw mounting seat 45 moves toward the clamping limit seat 410 and can abut against the clamping limit seat 410, and the stroke of the clamping jaw mounting seat 45 and the clamping jaw 42 is limited by the clamping limit seat 410, and the impact force when the clamping jaw mounting seat 45 abuts against the clamping limit seat 410 is buffered by the buffer pad 411.

[0131] Preferably, if Fig.10 As shown, the clamping jaw mounting seat 45 is provided with an escape groove which runs through from left to right, and the intermediate positioning conveying roller 30 is inserted in the escape groove to avoid the movement of the clamping jaw mounting seat 45 from interfering with the intermediate positioning conveying roller 30. The clamping jaw mounting seat 45 is movably mounted on the clamping guide rod 44 through a linear bearing. The clamping jaw 42 has a V-shaped positioning groove 421. When a pair of clamping jaws 42 clamp the prestressed end face flange, the V-shaped positioning groove 421 abuts against the outer periphery of the prestressed end face flange, playing a certain corrective role.

[0137] Preferably, if Fig.12 As shown, the upper ends of the first stop lever 521, the second stop lever 522, the third stop lever 523 and the fourth stop lever 524 are all fixed with a shock absorbing ring 513, and the shock absorbing ring 513 contacts the prestressed end face flange to reduce the impact force when the prestressed end face flange abuts. In addition, a sensor shield 514 is fixed on the detection bracket plate 512, and the two second proximity switches 56 are covered by the sensor shield 514 to prevent concrete residues from falling on the second proximity switches 56.

[0138] Furthermore, if Figure 3 and Fig.13As shown, the positioning and conveying device also includes an in-station hole position detection component 60, which includes a detection fixed bracket 61 fixed to the frame 20, a first sensor mounting bracket 62 fixed to the detection fixed bracket 61, and two first photoelectric sensors 63 fixed to the first sensor mounting bracket 62; the first sensor mounting bracket 62 is distributed on the side of the area above the positioning and conveying roller 30 to avoid interference with the scraper in the cleaning device; the two first photoelectric sensors 63 are distributed in a front-to-back interval, and the two first photoelectric sensors 63 are both inclined and can be aligned with the sealing plate 103 of the head plate flange 101 or the flange hole 104 of the tail plate flange 102 conveyed by the positioning and conveying roller 30. When the prestressed end face flange on the cleaning station is the head plate flange 101, the emission light of the first photoelectric sensor 63 is blocked and reflected back, and the first photoelectric sensor 63 outputs a stronger signal; when the prestressed end face flange on the cleaning station is the tail plate flange 102, the emission light of the first photoelectric sensor 63 is not blocked, the light will not be reflected back, and the first photoelectric sensor 63 outputs a weaker signal. In this way, the type of the prestressed end face flange can be identified and distinguished according to the output signal of the first photoelectric sensor 63 .

[0139] Furthermore, if Figure 3 As shown, the positioning and conveying device also includes four sets of cross-beam detection components 70, which are successively distributed along the conveying direction of the prestressed end face flange, and the last set of cross-beam detection components 70 and the flange stop component 52 are successively and closely distributed along the conveying direction of the prestressed end face flange. Fig.14 As shown, each set of the through-beam detection assembly 70 includes a second sensor mounting frame 71 fixed to the frame 20, and a through-beam sensor 72 fixed to the second sensor mounting frame 71, and the transmitter 721 and the receiver 722 of the through-beam sensor 72 are arranged opposite to each other in a direction perpendicular to the conveying direction of the prestressed end face flange. Through four sets of through-beam detection assemblies 70, the presence and size of the prestressed end face flange can be determined in combination. At the same time, through the frontmost set of through-beam detection assemblies 70, it can be determined whether the prestressed end face flange is conveyed forward to the positioning stop assembly 50, which is used to control whether the clamping drive source 41 controls the action control of closing a pair of clamping jaws 42.

[0140] Furthermore, if Figure 3 and Fig.15As shown, the positioning and conveying device also includes an error-proofing detection component 80, which includes a third sensor mounting frame 81 fixed to the frame 20, and a pair of second photoelectric sensors 82 fixed to the third sensor mounting frame 81. The pair of second photoelectric sensors 82 are distributed opposite to each other in a direction perpendicular to the conveying direction of the prestressed end face flange and are higher than the prestressed end face flange conveyed by the positioning and conveying roller 30. When there is a foreign object with a high height passing through the surface of the prestressed end face flange, the light of the second photoelectric sensor 82 is blocked, thereby realizing error-proofing detection, and the error-proofing detection component 80 sends an alarm signal. At this time, the worker intervenes to remove the prestressed end face flange in an abnormal state to prevent damage to the equipment in the subsequent process links.

[0141] Preferably, if Figure 5 As shown, C-shaped guide rails 210 extending forward and backward are fixed to the left and right sides of the frame 20, and the detection fixing bracket 61 in the station hole position detection component 60, the second sensor mounting bracket 71 in the through-beam detection component 70, and the third sensor mounting bracket 81 in the error prevention detection component 80 are all fixed to the square nuts by screws, and the square nuts are fixed in the slide groove of the C-shaped guide rail 210 with clearance fit, so as to facilitate the installation and fixation of the station hole position detection component 60, the through-beam detection component 70 and the error prevention detection component 80 on the frame 20.

[0142] Furthermore, if Figure 3 and Fig.16 As shown, the positioning and conveying device also includes a brush cleaning assembly 90, which is arranged at the end of the prestressed end face flange conveying path, that is, at the front end, and is located above the positioning and conveying roller 30. The brush cleaning assembly 90 includes a pair of brush fixing frames 91 fixed to the frame 20, two brush connecting brackets 92 fixed between the pair of brush fixing frames 91, and two row brushes 93 fixed on each brush connecting bracket 92. The pair of brush fixing frames 91 are arranged opposite to each other in the direction perpendicular to the conveying direction of the prestressed end face flange, and the brush connecting bracket 92 is inclined. The prestressed end face flange cleaned by the cleaning device continues to be conveyed forward, and then passes through the brush cleaning assembly 90, and the concrete residue on the surface of the prestressed end face flange is cleaned by the row brush 93.

[0143] In summary, the working principle of the positioning and conveying device with the above structure is as follows: in the initial state, a pair of clamping claws 42 are in an open state, and the first stop rod 521, the second stop rod 522, the third stop rod 523 and the fourth stop rod 524 are all in a raised state. When the rear-end shooting detection component 70 detects that a prestressed end face flange passes through the positioning and conveying roller 30, the size of the prestressed end face flange is determined, and at the same time, the station hole position detection component 60 determines the type of the prestressed end face flange, and the error-proofing detection component 80 determines whether there is an abnormality; if there is an abnormality, an alarm signal is sent to notify manual intervention. If there is no abnormality, the first stop rod 521 and the fourth stop rod 524 are controlled to descend, or the second stop rod 522 and the third stop rod 523 are controlled to descend according to the size of the prestressed end face flange. The positioning conveying roller 30 conveys the prestressed end face flange to be cleaned forward until the prestressed end face flange abuts against the second stop rod 522 and the third stop rod 523, or abuts against the first stop rod 521 and the fourth stop rod 524. The clamping drive source 41 drives a pair of clamping claws 42 to perform a clamping action to correct and fix the position of the prestressed end face flange. Subsequently, the second stop rod 522 and the third stop rod 523 are lowered, or the first stop rod 521 and the fourth stop rod 524 are lowered; the cleaning device above the positioning conveying device automatically cleans the prestressed end face flange at the cleaning station to remove the concrete attached to the surface of the prestressed end face flange. After the cleaning is completed, the clamping drive source 41 drives a pair of clamping claws 42 to perform an opening action, and the positioning conveying roller 30 continues to convey the cleaned prestressed end face flange forward, and the brush cleaning assembly 90 cleans the concrete residue on the surface of the prestressed end face flange. Finally, the first stop lever 521 , the second stop lever 522 , the third stop lever 523 and the fourth stop lever 524 all rise and reset to the initial state to enter the next working cycle.

[0144] Therefore, the positioning and conveying device involved in the present application can not only convey the prestressed end face flange, but also position and clamp the prestressed end face flange, which provides the prerequisite for automatically cleaning the concrete attached to the surface of the prestressed end face flange, which is beneficial to saving labor costs, improving cleaning efficiency and quality, and avoiding pits on the surface of the prestressed end face flange of the precast pile caused by hitting with a shovel.

[0145] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
