Description

Technical Field

[0001] The utility model relates to the technical field of precast pile production, in particular to a downline conveying device for conveying prestressed end face flanges of precast piles. 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, there are mainly two ways to clean the prestressed end face flange:

[0005] Method 1: Workers complete the work on the ground; workers need to carry and flip the prestressed end flange. The weight of the prestressed end flange used in the automated cage reinforcement production line is 15 to 62 kg, and workers also need to use a shovel to knock and scrape it to clean it. 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 flange, reducing the service life of the prestressed end flange.

[0006] Method 2: It is completed by cleaning equipment; for example, a cleaning device for the head and tail plates of pipe piles disclosed in the Chinese utility model patent with authorization announcement number CN218797676U is used, which places the head and tail plates on the front conveyor line, which conveys the head and tail plates, and the cleaning components complete the cleaning of the head and tail plates, and finally the rear conveyor line outputs the cleaned head and tail plates. However, the rear conveyor line only has a conveying function, and cannot distinguish the head plate flange and the tail plate flange well, which is not conducive to the automatic classification of the head plate flange and the tail plate flange.

[0097] The utility model provides a downline conveying device for conveying a prefabricated pile prestressed end face flange, the prestressed end face flange comprises 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 offline conveying device is defined as the forward direction.

[0098] like Figure 3 and Figure 4 As shown, the offline conveying device involved in the utility model includes a frame 20, an offline conveying driving source 30 installed on the frame 20, and several offline conveying rollers 40 that are rotatably installed on the frame 20, the several offline conveying rollers 40 are arranged side by side in front and back, and all extend left and right, the offline conveying driving source 30 is connected to the several offline conveying rollers 40 in a transmission manner, and drives the offline conveying rollers 40 to convey the prestressed end face flange forward. In particular, the offline conveying device also includes a head and tail plate detection component 50, an offline stop component 60, and a first unloading station 71 and a second unloading station 72 both arranged on the conveying path of the prestressed end face flange. Among them, the first unloading station 71 and the second unloading station 72 are distributed in sequence along the conveying direction of the prestressed end face flange, that is, the first unloading station 71 is distributed on the rear side of the second unloading station 72, and the prestressed end face flange conveyed forward is first conveyed to the first unloading station 71. The head and tail plate detection assembly 50 includes a detection sensor 51 aimed at the first blanking station 71, and is used to detect whether the prestressed end face flange at the first blanking station 71 is the head plate flange 101 or the tail plate flange 102. Figure 3 and Figure 7As shown, the down-line stop assembly 60 includes a down-line stop drive source 61 installed on the frame 20, and a liftable flange stop member 62. The down-line stop drive source 61 is transmission-connected to the flange stop member 62. The flange stop member 62 is liftably arranged in the gap between two adjacent down-line conveying rollers 40 and between the first unloading station 71 and the second unloading station 72.

[0099] The offline conveying device involved in the present application is used in the automatic cleaning production line of prestressed end face flanges, and is used to receive and convey the cleaned prestressed end face flanges forward. Figure 3 As shown, the cleaned prestressed end face flange is conveyed to the entrance end of the rear end of the offline conveying device; the offline conveying drive source 30 is activated to drive several offline conveying rollers 40 to rotate, and the offline conveying rollers 40 convey the prestressed end face flange forward. The prestressed end face flange is first conveyed forward to the first unloading station 71, and the head and tail plate detection component 50 detects the type of the prestressed end face flange to determine whether it is a head plate flange 101 or a tail plate flange 102. When the prestressed end face flange at the first unloading station 71 is judged to be the head plate flange 101, the offline stop drive source 61 drives the flange stop member 62 to be in an ascending state, and stops the head plate flange 101 at the first unloading station 71; when the prestressed end face flange at the first unloading station 71 is judged to be the tail plate flange 102, the offline stop drive source 61 drives the flange stop member 62 to be in a descending state, and the tail plate flange 102 continues to be conveyed forward until it is conveyed forward to the second unloading station 72. Alternatively, when it is determined that the prestressed end face flange at the first unloading station 71 is the tail plate flange 102, the lower line stop driving source 61 drives the flange stop member 62 to be in an ascending state, and stops the tail plate flange 102 at the first unloading station 71; when it is determined that the prestressed end face flange at the first unloading station 71 is the head plate flange 101, the lower line stop driving source 61 drives the flange stop member 62 to be in a descending state, and the head plate flange 101 continues to be conveyed forward until it is conveyed forward to the second unloading station 72.

[0100] Therefore, the present application effectively distinguishes the head plate flange 101 and the tail plate flange 102 through the cooperation of the head and tail plate detection component 50 and the downline stop component 60, and transports the head plate flange 101 and the tail plate flange 102 to two unloading stations respectively, thereby realizing automatic distinction and classification of the head plate flange 101 and the tail plate flange 102, and facilitating the subsequent circulation operation of the head plate flange 101 and the tail plate flange 102.

[0101] Furthermore, if Figure 3 and Figure 4As shown, the offline conveying drive source 30 is a motor, preferably a variable frequency reduction motor, which is fixedly mounted on the frame 20 through a motor fixing bracket and distributed below the offline conveying roller 40; the offline conveying drive source 30 is connected to several offline conveying rollers 40 through a sprocket chain mechanism. Figure 4 and Figure 6 As shown, the frame 20 is a frame structure formed by welding multiple columns and beams, and a foot cup 21 and a ground anchor 22 are installed at the lower end of each column; the foot cup 21 is used to adjust the height of the column where it is located, that is, to adjust the overall height and balance of the frame 20; the ground anchor 22 is used to fix the frame 20 to the ground to improve the stability of the offline conveyor. In addition, Figure 4 and Figure 5 As shown, a roller protection cover 23 is fixed to the upper end of the frame 20 to cover the sprocket chain mechanism to prevent the sprocket chain mechanism from being contaminated by concrete residues.

[0102] Furthermore, if Figure 4 and Figure 5 As shown, the offline conveying device also includes a plurality of guide units spaced apart from each other along the conveying direction of the prestressed end face flange, such as Figure 4 and Figure 5 In the embodiment shown, there are two groups of guide units. Each guide unit includes two groups of guide assemblies 130 symmetrically arranged in a direction perpendicular to the conveying direction of the prestressed end face flange, and each group of guide assemblies 130 includes a guide mounting plate 131 fixed to the frame 20, and a guide rod 132 fixed to the inner side of the guide mounting plate 131. The guide rod 132 extends straightly forward and backward along the conveying direction of the prestressed end face flange and is distributed on the upper side of the offline conveying roller 40. Through the guide rod 132, the prestressed end face flange can be guided to the center position of the offline conveying device to prevent the prestressed end face flange from excessive deviation.

[0103] Furthermore, the structure of the lower line stop assembly 60 is preferably as follows: Figure 7 and Figure 8As shown, the downline stop assembly 60 also includes a downline stop mounting plate 63 fixed to the frame 20, and a pair of downline stop brackets 64 fixed to the downline stop mounting plate 63. The pair of downline stop brackets 64 are opposite to each other in a direction perpendicular to the conveying direction of the prestressed end face flange. The left and right ends of the flange stop member 62 are respectively supported in the pair of downline stop brackets 64 so as to be movable up and down. The downline stop driving source 61 is a cylinder installed at the bottom of the downline stop mounting plate 63. The upper end of the piston rod of the cylinder is connected to the flange stop member 62 through a floating joint 68. In this way, when the cylinder piston rod of the downline stop driving source 61 extends upward, the flange stop member 62 is directly driven to move upward, so that it is in a rising state higher than the downline conveying roller 40; when the cylinder piston rod of the downline stop driving source 61 is retracted downward, the flange stop member 62 is directly driven to move downward, so that it is in a descending state lower than the downline conveying roller 40.

[0104] Preferably, if Figure 7 As shown, the lower line stop assembly 60 also includes a first sensor bracket 65 fixed to the lower line stop mounting plate 63, two proximity switches 66 arranged up and down and both fixed to the first sensor bracket 65, and a detection sensing member 67 fixed to the flange stop member 62, and both proximity switches 66 can sense the detection sensing member 67, and the detection sensing member 67 is a hexagonal bolt. When the lower line stop driving source 61 drives the flange stop member 62 to move downward, the detection sensing member 67 moves downward with the flange stop member 62, and the lower side proximity switch 66 can sense the detection sensing member 67, then the lower side proximity switch 66 is triggered; when the lower line stop driving source 61 drives the flange stop member 62 to move upward, the detection sensing member 67 moves upward with the flange stop member 62, and the upper side proximity switch 66 can sense the detection sensing member 67, then the upper side proximity switch 66 is triggered. Therefore, according to the signals of the upper and lower proximity switches 66, the position information of the flange stopper 62 is accurately fed back, and then the descending state or ascending state of the flange stopper 62 is accurately determined, thereby improving the control accuracy.

[0105] Preferably, if Figure 7 and Figure 8As shown, the flange stopper 62 includes a horizontally arranged stopper base plate 621, a stopper main plate 622 fixed at the rear end of the stopper base plate 621 toward the first unloading station 71 and vertically arranged, a stopper end plate 623 fixed between the left and right ends of the stopper base plate 621 and the stopper main plate 622, and a stopper pin shaft 624 fixed in the stopper end plate 623. The stopper base plate 621 and the stopper main plate 622 both extend straightly left and right in a direction perpendicular to the conveying direction of the prestressed end face flange. The downline stopper bracket 64 is provided with a slide groove extending up and down toward the inner side of the flange stopper 62, and the stopper pin shaft 624 extends left and right. The stopper pin shaft 624 is supported in the slide groove by a bearing so as to be movable up and down, thereby realizing that the flange stopper 62 is supported in a pair of downline stopper brackets 64 so as to be movable up and down. In addition, a plurality of reinforcing ribs 625 spaced left and right are fixed between the stopper base plate 621 and the stopper main plate 622 to improve the structural strength of the flange stopper 62.

[0106] Furthermore, the structure of the head and tail plate detection component 50 is preferably as follows: Fig. 9 As shown, the head and tail plate detection assembly 50 also includes a sensor connection bracket 52 and a sensor mounting plate 53. The sensor connection bracket 52 is fixed to the frame 20 and has a bracket suspension beam 521 located directly above the first unloading station 71. The bracket suspension beam 521 extends straightly to the left and right. The sensor mounting plate 53 is fixed to the bracket suspension beam 521. The detection sensor 51 is a photoelectric sensor and is fixed to the sensor mounting plate 53. When the prestressed end face flange on the first unloading station 71 is the head plate flange 101, the emission light of the photoelectric sensor is reflected back, and the photoelectric sensor outputs a stronger signal; when the prestressed end face flange on the first unloading station 71 is the tail plate flange 102, since the middle of the tail plate flange 102 is a flange hole 104, the emission light of the photoelectric sensor will not be reflected back, and the photoelectric sensor outputs a weaker signal. In this way, the type of the prestressed end face flange on the first unloading station 71 can be identified and distinguished according to the output signal of the photoelectric sensor.

[0107] Preferably, if Fig. 9As shown, there are multiple detection sensors 51, and the multiple detection sensors 51 are arranged side by side in a direction perpendicular to the conveying direction of the prestressed end face flange. The multiple detection sensors 51 are each fixed to the bracket suspension beam 521 through a sensor mounting plate 53. By arranging multiple detection sensors 51, the head and tail plate detection assembly 50 can detect prestressed end face flanges of various sizes, ensuring the accuracy of distinguishing the head plate flange 101 and the tail plate flange 102. In addition, a first sensor mounting rail 54 extending left and right is fixed to the upper end of the bracket suspension beam 521, and a square nut is fixed in the slide groove of the first sensor mounting rail 54 with clearance fit. The sensor mounting plate 53 is fixed to the first sensor mounting rail 54 by a fastening bolt, and the lower end of the fastening bolt is tightened in the square nut, which facilitates the fixed installation of the sensor mounting plate 53 on the bracket suspension beam 521.

[0108] Furthermore, if Figure 3 As shown, the offline conveying device also includes an in-place detection component 90, and the in-place detection component 90 and the flange stopper 62 are successively and closely distributed along the conveying direction of the prestressed end face flange. Fig.10 As shown, the in-position detection assembly 90 includes a second sensor bracket 91 fixed to the rack 20, and a through-beam sensor 92 fixed to the second sensor bracket 91. The transmitter 921 and the receiver 922 of the through-beam sensor 92 are arranged opposite to each other in the direction perpendicular to the conveying direction of the prestressed end face flange. The transmitter 921 and the receiver 922 of the through-beam sensor 92 are respectively fixed to the left and right sides of the rack 20 through a second sensor bracket 91. When there is no prestressed end face flange between the transmitter 921 and the receiver 922, the receiver 922 can receive the light emitted by the transmitter 921; when there is a prestressed end face flange between the transmitter 921 and the receiver 922, the light emitted by the transmitter 921 is blocked by the prestressed end face flange, and the receiver 922 cannot receive the light emitted by the transmitter 921. Therefore, according to the output of the receiver 922 , it is possible to determine whether there is a prestressed end face flange there, that is, to determine whether the prestressed end face flange is conveyed to the rear side of the flange stopper 62 , that is, whether it is conveyed to the first unloading station 71 .

[0109] Furthermore, if Figure 3As shown, along the conveying direction of the prestressed end face flange forward, the frame 20 is fixed with a material blocking bracket 110 and a laser detector 120 at the end of the front side of the prestressed end face flange conveying path.

The containing tank 82 contains a release agent, and the release agent covers the outer peripheral surface of the upper coating roller 83 through the rotation and contact of the lower coating roller 84 and the upper coating roller 83. When the prestressed end face flange is conveyed forward, the upper coating roller 83 contacts and cooperates with the prestressed end face flange, and then the release agent is automatically and evenly applied to the surface of the prestressed end face flange.

[0112] Furthermore, if Figures 11 to 13As shown, the roller brush coating assembly 80 also includes a connecting shaft 85 rotatably supported in the roller brush coating assembly 80, the upper coating roller 83 and the lower coating roller 84 both include a roller shaft 814, a roller body 86 fixed on the roller shaft 814, and a roller flannel 87 fixed on the outer periphery of the roller body 86, the connecting shaft 85 is connected to the first offline conveying roller 40 through a first transmission assembly, the connecting shaft 85 is connected to the roller shaft 814 of the upper coating roller 83 through a universal joint 813, and the roller shaft 814 of the upper coating roller 83 and the roller shaft 814 of the lower coating roller 84 are connected through a second transmission assembly. Preferably, the first transmission assembly and the second transmission assembly are both sprocket chain mechanisms, and a transmission sprocket 88 is fixed on the connecting shaft 85 and the roller shaft 814 of the upper coating roller 83 and the lower coating roller 84. In the present application, the rotational power of the first transmission assembly and the second transmission assembly comes from the offline conveying drive source 30, which reduces the equipment cost.

The roller brush coating assembly 80 also includes a scraper plate 810 extending left and right. The left and right ends of the scraper plate 810 are respectively fixed to the roller support frame 89. The scraper plate 810 is arranged on the outer peripheral side of the upper coating roller 83 and contacts the roller flannel 87 on the outer periphery of the upper coating roller 83. The scraper plate 810 is used to scrape off excess oil on the upper coating roller 83 to avoid excessive oil.
