[0002] With the rapid development of my country's economy, the demand for pipe piles has greatly increased. This is because due to the soil squeezing effect, pipe piles can squeeze the soft soil layer and thus improve the bearing capacity of the soft soil foundation. Therefore, pipe piles are widely used in the construction industry. For example, railways, highways, bridges, etc. all need pipe piles to lay the foundation.

[0003] Specifically, the pipe pile is composed of concrete and cage reinforcement, and the cage reinforcement is composed of round steel bars, straight steel bars, spiral steel bars, and other types of steel bars. After the cage reinforcement is roll-welded by the roll welding machine, the cage reinforcement enters the next riveting process. Before riveting, the hoops need to be respectively inserted into the two ends of the cage reinforcement, and then the cage reinforcement is sent to the rotary riveting equipment by the transfer equipment, and the hoops are riveted to the cage reinforcement by the rotary riveting equipment. However, there are inevitably errors in the height dimensions of the hoops produced by the existing hoops production equipment, and since the position of the rivet cutter in the rotary riveting equipment is fixed, if there is an error in the height dimension of the hoops, it will cause position deviations during subsequent riveting, resulting in unstable product quality.

[0032] An embodiment of the present application provides a ferrule height measuring device, which is used to measure the height of the ferrule before the ferrule is riveted to the cage reinforcement by a rotary riveting device, so as to avoid a large error in the height of the produced ferrule, resulting in position deviation during riveting in subsequent processes and causing unstable product quality.

[0033] The structure of the ferrule height measuring device in the present application is described below. It is understandable that in other embodiments, the ferrule centering device of the present application is not limited to being used only for measuring the height of the ferrule, but can also be used for measuring the height of any cylindrical workpiece, which is not limited here.

[0034] Referring to Fig. 1, Fig. 1 shows a schematic diagram of the structure of a hoop height measuring device 10 in an embodiment of the present application. The hoop height measuring device 10 provided in an embodiment of the present application comprises a bracket 100 and a height measuring mechanism 200, wherein the bracket 100 is a frame structure formed by splicing a plurality of profiles and plates, and has a bearing surface 101 for bearing the hoop 80, and the height measuring mechanism 200 is arranged on the bracket 100, and is used to measure the height dimension of the hoop 80 when the bearing surface 101 of the bracket 100 bears the hoop 80.

[0035] Specifically, Figure 2As shown, in one embodiment, the height measuring mechanism 200 includes a mounting seat 210, a first driving source 220, a first pressing plate 230 and a measuring module 240, wherein the mounting seat 210 is mounted on a side edge of the bracket 100, the first driving source 220 is arranged on the mounting seat 210, the first pressing plate 230 is connected to the output end of the first driving source 220, and the measuring module 240 is mounted on the mounting seat 210 and connected to the first pressing plate 230. The first driving source 220 may be a cylinder or a hydraulic cylinder controlled by a solenoid valve, which is used to drive the first pressing plate 230 to rise and fall relative to the bracket 100 in a vertical direction, so that the first pressing plate 230 can be pressed against the top end of the hoop 80; the measuring module 240 is used to measure the height of the hoop 80 when the hoop 80 is carried on the bearing surface 101 and the first pressing plate 230 presses the top end of the hoop 80.

[0036] More specifically, the first pressing plate 230 is connected to the output end of the first driving source 220 through the connecting assembly 250, wherein one end of the connecting assembly 250 is connected to the output end of the first driving source 220, and the first pressing plate 230 is arranged at the end of the connecting assembly 250 away from the first driving source 220. Preferably, the end of the connecting assembly 250 away from the first driving source 220 is provided with a second driving source 260, and the first pressing plate 230 is connected to the output end of the second driving source 260. The second driving source 260 can also be a cylinder, etc., which is used to drive the first pressing plate 230 to rotate around an axis extending in the vertical direction, so that the hoop 80 can be avoided when the manipulator grabs the hoop 80 and transfers the hoop 80 after the measurement is completed, so as to prevent the hoop 80 from colliding with the height measuring mechanism 200.

[0037] In a specific embodiment, Figure 2 As shown, the connecting assembly 250 includes a first mounting plate 251, a second mounting plate 252 and a guide rod 253. The first mounting plate 251 is connected to the output end of the first driving source 220. The second mounting plate 252 is arranged above the first mounting plate 251 at intervals in the vertical direction. The second driving source 260 is arranged on the second mounting plate 252. One end of the guide rod 253 is connected to the first mounting plate 251, and the other end is connected to the second mounting plate 252. In order to make the first driving source 220 drive the connecting assembly 250 to drive the first pressing plate 230 to rise and fall smoothly in the vertical direction, the mounting seat 210 has a connecting plate 211 extending in the horizontal direction. A guide sleeve 212 is provided on one side of the connecting plate 211 close to the first mounting plate 251. The guide rod 253 is penetrated by the guide sleeve 212 and the connecting plate 211, so that the guide rod 253 can only move in the vertical direction under the guidance of the guide sleeve 212, thereby ensuring that the first pressing plate 230 can rise and fall smoothly and can be pressed horizontally against the top of the hoop 80.

[0038] In one embodiment, the measuring module 240 includes a measuring element and a control element, wherein the measuring element is a displacement sensor and the control element is a PLC controller. When performing measurement, the first driving source 220 drives the first pressing plate 230 to rise to an initial position, the measuring element collects the height signal of the initial position, and the control element converts the height signal of the initial position into a numerical value M; then, the first driving source 220 drives the first pressing plate 230 to descend a certain distance until the first pressing plate 230 is pressed against the top of the hoop 80, and the measuring element then collects the signal of the height of the first pressing plate 230 that has descended, and the control element converts the signal of the height of the first pressing plate 230 that has descended into a numerical value N, and the height of the hoop 80 can be calculated by subtracting M from N.

[0039] Further, when the hoop 80 is placed on the bearing surface 101, in order to make the center of the hoop 80 coincide with a center point on the bearing surface 101, in combination with FIG. Figure 3 As shown, the bearing surface 101 is provided with a plurality of guide assemblies 110, and all the guide assemblies 110 surround a central axis 90 extending in the vertical direction. When the ferrule 80 is grasped by the robot and is about to be placed on the bearing surface 101, under the guiding action of the guide assemblies 110, it is easier to make the central axis of the ferrule 80 coincide with the center point on the bearing surface 101 (that is, coincide with the central axis 90 surrounded by the plurality of guide assemblies 110).

[0040] In terms of the structure of the guide assembly 110, each guide assembly 110 includes a plurality of guide pins 111, and the guide pins 111 of each guide assembly 110 are arranged at intervals along the radial direction defined by the central axis 90. In this way, because each guide assembly 110 includes a plurality of guide pins 111, when the ferrules 80 of different diameters are grasped and placed on the bearing surface 101 by the robot, they can all be inserted into the gap formed by two adjacent guide posts, so that they can be guided so that the central axis 90 of the ferrule 80 coincides with the central axis 90 surrounded by the plurality of guide assemblies 110.

[0041] Furthermore, when the height of the hoop 80 is measured by the height measuring mechanism 200, in order to fix the hoop 80 to prevent the hoop 80 from moving at will, please continue to refer to Figure 1. The hoop height measuring device 10 also includes a pressing mechanism 300, and the pressing mechanism 300 includes a third driving source 310 and a second pressing plate 320. The third driving source 310 is installed at the edge of the bracket 100, and the second pressing plate 320 is connected to the output end of the third driving source 310. Under the drive of the third driving source 310, the second pressing plate 320 can be controlled to rise and fall in the vertical direction like the first pressing plate 230, and / or rotate around an axis extending in the vertical direction, so as to press the top of the hoop 80 to prevent the hoop 80 from moving at will when the height is measured, and to avoid the hoop 80 when the manipulator grabs the hoop 80 and rises. It will not be repeated here.

[0042] In addition, in some improved embodiments, the bracket 100 is further provided with a pressure regulating valve 400, which is used to adjust the driving pressure of the first driving source 220, the second driving source 260 or the third driving source 310. Optionally, a detection element 500 is further provided on the bearing surface 101, and the detection element 500 can be a photoelectric device, etc., which is used to detect whether the hoop 80 is carried on the bearing surface 101. Optionally, the hoop height measuring device 10 also includes a base 600, which is used to connect to the ground, and the bracket 100 is connected to the base 600 by an adjusting bolt 700, and the adjusting bolt 700 is used to adjust the height of the bracket 100 and the ground, so that the overall installation height of the hoop height measuring device 10 can be adjusted.

[0043] It can be seen that when the height of the hoop is measured using the hoop height measuring device provided in the present application, the measuring module can quickly measure the height of the hoop, so the operation is convenient. Before the hoop is put on the end of the cage reinforcement, the height of the hoop can be measured with a simple mechanical structure to determine whether the height dimension of the hoop is within the specified range, thereby avoiding the problem of large error in the height of the produced hoop, resulting in position deviation during riveting in subsequent processes and causing unstable product quality.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
