Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a concrete pipe socket size detection auxiliary device. Background Art

[0002] Concrete pipes are made of concrete or reinforced concrete. Socket pipes are divided into rigid socket connections and flexible socket connections. The rigid socket connection is to insert the spigot of the pipe into the socket of the pipe. After alignment, the joints are first caulked with caulking materials, and then sealed with sealing materials to make it a solid and closed whole. In order to ensure that the sealing material fits the concrete socket, it is necessary to use measuring tools to detect the socket of the concrete pipe.

[0003] Most existing detection methods use a tape measure. The tape measure is pulled out and one end of the tape measure is restricted to the concrete socket by the palm. The tape measure is rotated with one end of the tape measure as the center. The maximum measuring distance is read as the diameter of the concrete socket. When one end of the tape measure is not held firmly and deviates, there will be a certain error in the measurement result and re-measurement is required, which slows down the detection speed and makes the operation more inconvenient. Utility Model Content

[0004] The utility model aims to provide a concrete pipe socket size detection auxiliary device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A concrete pipe socket size detection aid comprises a fixed frame, an extension component is symmetrically fixedly embedded and installed on the outer surface of the fixed frame, the extension component comprises a No. 1 hollow rod fixedly embedded and installed on the outer surface of the fixed frame, a No. 2 hollow rod is slidably connected inside the No. 1 hollow rod, an adjustment component is fixedly installed on one end of the No. 2 hollow rod, the adjustment component comprises a telescopic rod fixedly installed on the surface of one end of the No. 2 hollow rod, a fixed frame is fixedly installed on one end of the telescopic rod, a roller is rotatably connected inside the fixed frame, a flipping component is fixedly installed on the outer surface of the telescopic rod, the flipping component comprises a connecting seat fixedly installed on the outer surface of the telescopic rod, a flap is rotatably connected inside the connecting seat, and a clamping assembly is provided on one side of the flap.

[0007] Furthermore, a pressure sensor No. 1 is fixedly mounted on the surface of one end of the telescopic rod, and a spring is movably arranged on one side of the pressure sensor No. 1 inside the telescopic rod.

[0008] Furthermore, one end of the flap passes through the connecting seat and is fixedly installed with a No. 1 gear, the outer surface of the telescopic rod is fixedly installed with a slide rail, the inside of the slide rail is slidably connected with a No. 1 tooth plate that is movably meshed with the No. 1 gear, and one side surface of the slide rail is fixedly installed with an electric push rod that is fixedly connected to the No. 1 tooth plate.

[0009] Furthermore, a No. 1 motor is fixedly embedded and installed on one side surface of the fixed frame, a No. 1 bevel gear is fixedly installed on the output end of the No. 1 motor, a fixed ring is symmetrically fixedly installed inside the fixed frame, a No. 2 bevel gear is rotatably connected inside the fixed ring, and the No. 1 bevel gear is movably meshed with two No. 2 bevel gears respectively.

[0010] Preferably, a threaded sleeve is fixedly installed at one end of the inner surface of the No. 2 hollow rod, a screw rod is screwed inside the threaded sleeve, and one end of the screw rod is fixedly connected to the adjacent No. 2 bevel gear.

[0011] Furthermore, the clamping assembly includes a sliding sleeve fixedly mounted on one side surface of the flap, a No. 2 tooth plate is slidably connected inside the sliding sleeve, a rubber pressure rod is fixedly mounted on one end of the No. 2 tooth plate, a No. 2 pressure sensor is fixedly mounted inside the rubber pressure rod, and scale grooves are provided on one side surface of the No. 2 tooth plate and the telescopic rod.

[0012] Preferably: a No. 2 motor is fixedly mounted on a surface of one side of the flap, and a No. 2 gear movably meshed with a No. 2 gear plate is fixedly mounted on an output end of the No. 2 motor.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The No. 1 motor is operated to rotate the two screws, so that the threaded sleeve drives the No. 2 hollow rod to slide inside the No. 1 hollow rod, and the roller is pushed outward to adjust the position of the roller. The roller always presses against the inner wall of the socket. In the process of rolling to adjust the position, the distance between the two rollers gradually increases. The spring and the telescopic rod give the roller a certain elastic contraction distance. When the telescopic rod is contracted to the limit, the pressure of the spring on the No. 1 pressure sensor is at the set value. The PLC controller of the external device determines that the distance between the two rollers is maximized at this time, and then the detection value is quickly read through the scale groove on the outside of the telescopic rod, so that the roller is pushed to extend inside the concrete socket through the extension component, so that the roller rotates, and the position of the extension component is adjusted so that the two rollers press against the farthest inside the concrete socket, so as to quickly and accurately detect the inner diameter of the socket.

[0015] 2. The electric push rod contracts, causing the flap to drive the clamping assembly to flip, and the rubber pressure rod flips to the outside of the socket. Then the No. 2 motor runs to make the No. 2 tooth plate slide inside the sleeve, causing the rubber pressure rod to press against the outer wall of the socket. When the No. 2 pressure sensor senses the pressure, the external PLC controller determines that the rubber pressure rod is against the outer wall of the socket at this time, thereby driving the clamping assembly to flip through the flip assembly, and at the same time detecting the wall thickness and outer diameter of the concrete socket, thereby improving the speed of measuring the concrete socket data, increasing the accuracy of the detection data, and making the detection device easier to operate.

[0024] Specifically, the No. 1 motor 101 operates to expand the extension component 2 outward, push the roller 303 to move, make the roller 303 fit the inner wall of the concrete socket and rotate, maximize the distance between the two rollers 303 inside the concrete socket, measure the inner diameter of the socket, and then clamp the outer wall of the socket through the clamping component 5 to measure the outer diameter and wall thickness. Embodiment 1

[0025] like Figure 2 As shown, in this embodiment, a No. 1 motor 101 is fixedly embedded and installed on the surface of one side of the fixed frame 1, and a No. 1 bevel gear 102 is fixedly installed on the output end of the No. 1 motor 101. A fixing ring 103 is symmetrically fixedly installed inside the fixed frame 1, and a No. 2 bevel gear 104 is rotatably connected inside the fixing ring 103. The No. 1 bevel gear 102 is movably meshed with two No. 2 bevel gears 104 respectively; a threaded sleeve 203 is fixedly installed at one end of the inner surface of the No. 2 hollow rod 202, and a screw rod 204 is screwed and connected inside the threaded sleeve 203, and one end of the screw rod 204 is fixedly connected to the adjacent No. 2 bevel gear 104.

[0026] In this embodiment, the No. 1 motor 101 runs, driving the No. 1 bevel gear 102 to rotate, and through its active meshing with the No. 2 bevel gear 104, the two screw rods 204 rotate, and through the screw rod 204 and the threaded sleeve 203, the threaded sleeve 203 drives the No. 2 hollow rod 202 to slide inside the No. 1 hollow rod 201, pushing the roller 303 outward to adjust the position of the roller 303.

[0027] like Figure 5 As shown, in this embodiment, a pressure sensor No. 1 305 is fixedly mounted on the surface of one end of the telescopic rod 301 , and a spring 304 is movably provided on one side of the pressure sensor No. 1 305 inside the telescopic rod 301 .

[0028] During specific implementation, the roller 303 always presses against the inner wall of the socket. During the rolling adjustment process, the distance between the two rollers 303 gradually increases and finally reaches the inner diameter line of the socket. The spring 304 and the telescopic rod 301 enable the roller 303 to have a certain elastic contraction distance. When the telescopic rod 301 contracts to the limit, the pressure of the spring 304 on the No. 1 pressure sensor 305 is at the set value. The PLC controller of the external device determines that the distance between the two rollers 303 is maximized at this time, and then the detection value is quickly read through the scale groove on the outside of the telescopic rod 301, so that the roller 303 is pushed to extend inside the concrete socket through the extension component 2, so that the roller 303 rotates, and the position of the extension component 2 is adjusted so that the two rollers 303 press against the farthest part of the concrete socket, so as to quickly and accurately detect the inner diameter of the socket.

[0029] like Figure 3-5 As shown, in this embodiment, one end of the flap 402 passes through the connecting seat 401 and is fixedly installed with a No. 1 gear 403, the outer surface of the telescopic rod 301 is fixedly installed with a slide rail 404, and a No. 1 toothed plate 405 movably meshed with the No. 1 gear 403 is slidably connected inside the slide rail 404, and an electric push rod 406 fixedly connected with the No. 1 toothed plate 405 is fixedly installed on one side surface of the slide rail 404; the clamping assembly 5 includes a sliding sleeve 501 fixedly installed on one side surface of the flap 402, and a No. 2 toothed plate 502 is slidably connected inside the sliding sleeve 501, a rubber pressure rod 503 is fixedly installed at one end of the No. 2 toothed plate 502, and a No. 2 pressure sensor is fixedly installed inside the rubber pressure rod 503, and scale grooves are provided on the surface of one side of the No. 2 toothed plate 502 and the telescopic rod 301; a No. 2 motor 504 is fixedly installed on one side surface of the flap 402, and a No. 2 gear 505 movably meshed with the No. 2 toothed plate 502 is fixedly installed on the output end of the No. 2 motor 504.

[0030] During specific implementation, the electric push rod 406 contracts, and through the meshing transmission of the No. 1 gear 403 and the No. 1 tooth plate 405, the flap 402 drives the clamping assembly 5 to flip, and the rubber pressure rod 503 flips to the outside of the socket. Then the No. 2 motor 504 operates, and through the meshing transmission of the No. 2 gear 505 and the No. 2 tooth plate 502, the No. 2 tooth plate 502 slides inside the sliding sleeve 501, so that the rubber pressure rod 503 is pressed against the outer wall of the socket. When the No. 2 pressure sensor senses the pressure, the external PLC controller determines that the rubber pressure rod 503 is against the outer wall of the socket at this time, thereby driving the clamping assembly 5 to flip through the flipping assembly 4, and at the same time detecting the wall thickness and outer diameter of the concrete socket, thereby improving the speed of measuring the concrete socket data, increasing the accuracy of the detection data, and making the detection device easier to operate.

[0031] In the present invention, in order to facilitate the operator to control the utility model, a PLC controller can be set up, and the No. 1 motor 101, the electric push rod 406, the No. 1 pressure sensor 305, the No. 2 pressure sensor and the No. 2 motor 504 are all electrically connected to the PLC controller. The PLC controller is a prior art and will not be described in detail here.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
