Description

Technical Field

[0001] The present invention relates to the field of communication pipe detection, and in particular to a wear resistance detection device for textile pipes for communication. Background Art

[0002] With the gradual deepening of the urbanization process, the ground excavation caused by newly built pipelines is subject to more and more external interferences and policy restrictions, making the pipe hole resources of existing pipelines increasingly tense. In order to make full use of the existing communication pipeline resources, a textile pipe for communication that replaces the PE plastic sub-pipe is designed. By taking advantage of the small space occupied by the textile pipe itself and the ability to make full use of the pipe hole space, it helps to increase the number of cables that can be laid in the communication pipe holes of the same diameter. The specific use method of the textile pipe is to re-lay the textile pipe in the old pipeline where the cable has been laid, and then lay the optical cable or cable in the textile pipe again. The advantage of this mode is that it can fully explore the remaining space of the old pipeline and improve the utilization rate, but it has high requirements for the flexibility and wear resistance of the textile pipe, and it is necessary to use wear-resistant equipment to detect the performance of the textile pipe.

[0003] The applicant found that there are at least the following technical problems in the prior art: the existing wear resistance detection equipment for textile pipes can only detect the wear resistance by setting multiple sets of support shafts with different diameters to support textile pipes of different sizes. The range of textile pipe sizes that can be detected is limited, and the practicability is poor. Moreover, it cannot stop the wear detection process when the textile pipe wears to the preset thickness. It completely depends on the operator to visually judge the degree of wear and then manually turn off the wear detection process, resulting in poor detection accuracy and poor practicability. Summary of the Invention

[0004] The purpose of the present invention is to provide a wear resistance detection device for textile pipes for communication to solve the above problems. A pressure-bearing cylinder is set to cooperate with a tension roller to support the pipe body to be detected, so as to use the tension roller to tighten textile pipes of different sizes, thereby increasing the range of textile pipe sizes that the equipment can detect and improving the practicability. At the same time, a limit nut with adjustable position is set as a wear detection mark. During the detection process, the distance between the limit nut and the proximity switch is pre-adjusted as the wear thickness. When the wear reaches the preset wear thickness, the limit nut moves down with the support rod and the friction head to contact the proximity switch position, thereby automatically turning off the motor to stop the wear process, which is convenient for the detection personnel to judge the wear resistance of the textile pipe according to the working time of the motor during the process of reaching the set wear thickness, with higher detection accuracy and strong practicability. See the following description for details.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A wear resistance performance detection device for a communication textile tube provided by the present invention includes a mounting frame and a pressure-bearing cylinder. The pressure-bearing cylinder is horizontally arranged on one side of the middle of the mounting frame, and a motor for supporting the rotation of the pressure-bearing cylinder is arranged on the other side of the middle of the mounting frame. The motor is internally provided with a controller for recording the power-on time. An auxiliary component is arranged on the mounting frame above the pressure-bearing cylinder, and a detection frame is arranged at the bottom side of the auxiliary component. A tensioning roller for cooperatively tightening the tube to be detected with the pressure-bearing cylinder is arranged on the mounting frame below the pressure-bearing cylinder.

[0007] A chute is horizontally penetrated through the mounting frame below the motor. A slider is vertically slidably fitted inside the chute. A guide rod penetrating through the slider is vertically fixed in the middle of the chute, and the guide rod is slidably fitted with the slider. A spring is sleeved outside the guide rod above the slider. An installation shaft is connected between the slider and the tensioning roller, and the installation shaft is rotatably fitted with the tensioning roller. The detection frame is a U-shaped frame body with an upward opening. A support rod is vertically penetrated through the center of the bottom of the detection frame. A friction head that abuts against the outer surface of the tube to be detected is fixed at the bottom end of the support rod. The support rod is vertically slidably fitted with the detection frame. A tray for containing weights is fixed at the top end of the support rod. A limit nut is threadedly fitted on the outer side of the support rod below the tray. Proximity switches for disconnecting the power supply of the motor are arranged at the inner bottom of the detection frame on the front and rear sides of the support rod to contact the limit nut.

[0008] When using the above wear resistance performance detection device for a communication textile tube to perform wear detection on a textile tube as the tube to be detected, the flexible textile tube is sleeved between the tensioning roller and the pressure-bearing cylinder. The spring is used to move the slider downward to drive the tensioning roller to tighten the textile tube. Weights are placed on the tray to provide a downward pressure to the support rod and the friction head to ensure that the bottom of the friction head abuts against the outer surface of the top side of the textile tube. Then, the height position of the limit nut on the support rod is adjusted according to the required wear thickness to ensure that the distance between the bottom side of the limit nut and the proximity switch is equal to the required wear thickness. At this time, the motor is started to record the power-on time of the motor through the controller built in the motor. The output end of the motor drives the pressure-bearing cylinder to rotate, and the pressure-bearing cylinder is used to support the rotation of the tube to be detected. At this time, the friction head wears and consumes the outer side of the continuously rotating textile tube. When the wear thickness of the outer side of the textile tube reaches the preset thickness, at this time, the limit nut follows the support rod and the friction head to synchronously move downward by the same height as the wear thickness. The bottom side of the limit nut contacts the proximity switch at this time, so that the proximity switch controls the power-off of the motor. According to the power-on time of the motor recorded by the controller built in the motor, the time required for this group of textile tubes to wear to the set thickness can be obtained, so as to detect whether the wear resistance performance of this textile tube meets the requirements.

[0009] Preferably, the mounting frame is an L-shaped bent plate structure, and a rectangular frame-shaped reinforcement frame extending horizontally is fixed on the outer side of the bottom of the mounting frame.

[0010] Preferably, the outer end of the pressure-bearing cylinder is fixedly connected to the output end of the motor through a coupling. A driving rod is coaxially arranged inside the pressure-bearing cylinder. One end of the driving rod away from the motor penetrates out of the pressure-bearing cylinder, and a knob is fixed to the outer end of the driving rod.

[0011] Preferably, the pressure-bearing cylinder is of a hollow cylindrical structure. Four groups of laterally extending restraint grooves are arranged around both ends of the pressure-bearing cylinder. Two restraint sheets are arranged horizontally and side by side at both ends inside the pressure-bearing cylinder. The restraint sheets are in a "cross" shape structure. Four sides of the restraint sheets respectively penetrate out of the four groups of restraint grooves, and the restraint sheets are in horizontal sliding fit with the restraint grooves.

[0012] Preferably, two groups of external threads with opposite helix directions are arranged on the outer sides of both ends of the driving rod inside the pressure-bearing cylinder, and the driving rod is in threaded fit with the two restraint sheets through the two groups of external threads.

[0013] Preferably, the auxiliary component includes a square funnel-shaped storage hopper fixed to the side of the mounting frame. A transfer cover is vertically communicated with the bottom opening of the storage hopper. Both ends of the top of the detection frame are respectively fixed to the front and rear sides outside the transfer cover.

[0014] Preferably, an auxiliary cylinder for closing the bottom opening of the transfer cover is horizontally arranged at the bottom of the transfer cover. A transmission rod is coaxially fixed in the middle of the auxiliary cylinder. The auxiliary cylinder is rotationally matched with the transfer cover through the transmission rod. A transmission belt pulley is fixed to one end of the transmission rod close to the mounting frame. A driving belt pulley is fixed to the outside of the middle part of the output end of the motor. A transmission belt is connected in transmission between the driving belt pulley and the transmission belt pulley.

[0015] Preferably, accommodation cavities are arranged on both the upper and lower sides of the auxiliary cylinder. The openings of the accommodation cavities extend laterally to the end of the auxiliary cylinder away from the transmission belt. Restriction plates for closing the accommodation cavities are horizontally slidably matched inside the two accommodation cavities. The outer sides of the restriction plates are flush with the outer circumferential side of the auxiliary cylinder.

[0016] Preferably, a synchronous ring is vertically connected to one end of the two restriction plates away from the transmission belt pulley. A lead screw is horizontally penetrated inside the synchronous ring. The lead screw is in threaded fit with the synchronous ring. One end of the lead screw is rotationally matched with the outer end of the auxiliary cylinder through a thrust bearing, and a disc-shaped adjustment knob is fixed to the other end of the lead screw.

[0017] The beneficial effects are as follows: The present invention sets a pressure-bearing cylinder in cooperation with a tensioning roller to support the tube to be detected, so as to use the tensioning roller to tighten textile tubes of different sizes, thereby increasing the size range of textile tubes that the equipment can detect and improving the practicability.

[0018] Meanwhile, a position-adjustable limit nut is set as a wear detection mark. During the detection process, the distance between the limit nut and the proximity switch is pre-adjusted as the wear thickness. When the wear reaches the preset wear thickness, the limit nut follows the support rod and the friction head to move down to the position where it contacts the proximity switch, thereby automatically shutting down the motor to stop the wear process. This makes it convenient for the detection personnel to judge the wear resistance performance of the textile tube based on the working time of the motor during the process of reaching the set wear thickness. The detection accuracy is higher and the practicability is strong;

[0019] Two groups of constraint pieces with adjustable spacing are arranged on the pressure-bearing cylinder as the rotation limit structure of the textile tube. Furthermore, the two groups of constraint pieces are used to support both sides of the tube body to be detected with different width dimensions, ensuring the position stability of the textile tube as the tube body to be detected during the rotational wear detection process;

[0020] During the rotation of the auxiliary cylinder communicating with the transfer cover, the dust inside the transfer cover can alternately fall into the two accommodating cavities. Furthermore, during the up-and-down alternating rotation of the two accommodating cavities, the dust is discharged downward, thereby simulating the wear action of the textile tube in a dust-accumulating state. Moreover, the length of the limiting plate placed in the accommodating cavity can be adjusted, thereby changing the effective space in the accommodating cavity that can store dust, so as to change the falling speed of the dust under the condition that the rotation speed of the auxiliary cylinder remains unchanged, and realizing the wear resistance performance detection process of the tube material to be detected under different dust collection degrees.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present invention.

[0033] See Figures 1-8 As shown, the present invention provides a wear resistance detection device for a communication textile tube, including a mounting frame 1 and a pressure-bearing cylinder 2. The pressure-bearing cylinder 2 is horizontally arranged on one side of the middle of the mounting frame 1. On the other side of the middle of the mounting frame 1, there is a motor 3 that supports the rotation of the pressure-bearing cylinder 2. The motor 3 is internally provided with a controller for recording the power-on time. On the mounting frame 1 above the pressure-bearing cylinder 2, there is an auxiliary component 7. On the bottom side of the auxiliary component 7, there is a detection frame 6. On the mounting frame 1 below the pressure-bearing cylinder 2, there is a tensioning roller 4 that cooperates with the pressure-bearing cylinder 2 to tightly hold the pipe body 5 to be detected. The auxiliary component 7 is used to simulate the wear resistance of the textile tube in a dust environment in an ash-accumulated state;

[0034] A chute 101 runs horizontally through the mounting bracket 1 below the motor 3. A slider 103 is vertically slidably fitted inside the chute 101. A guide rod 102 passing through the slider 103 is vertically fixed in the middle of the chute 101, and the guide rod 102 is slidably fitted with the slider 103. A spring 102a is sleeved outside the guide rod 102 above the slider 103. An installation shaft 104 is connected between the slider 103 and the tensioning roller 4, and the installation shaft 104 is rotationally fitted with the tensioning roller 4. The spring 102a is used to push the slider 103 downward to support the tensioning roller 4 through the installation shaft 104 to tightly support the to-be-detected pipe body 5 downward. The detection frame 6 is a U-shaped frame body with an upward opening. A support rod 601 runs vertically through the center of the bottom of the detection frame 6. A friction head 602 that abuts against the outer surface of the to-be-detected pipe body 5 is fixed at the bottom end of the support rod 601. The friction head 602 is used as a grinding tool structure for the worn textile pipe. The support rod 601 is vertically slidably fitted with the detection frame 6. A tray 603 for holding weights is fixed at the top end of the support rod 601. The weights placed in the tray 603 are used to provide the pressing force of the friction head 602 against the outside of the textile pipe, so as to adjust the wear speed of the textile pipe under different extrusion forces by replacing weights of different weights, and to detect the wear resistance of the textile pipe in different environments by controlling various variables, thereby contributing to the further detection and research on the wear resistance of the textile pipe. A limit nut 605 is threadedly fitted on the outside of the support rod 601 below the tray 603, and proximity switches 604 for disconnecting the power supply of the motor 3 are arranged at the inner bottom of the detection frame 6 on the front and rear sides of the support rod 601 to contact the limit nut 605. The mounting bracket 1 is an L-shaped bent plate structure. A rectangular frame-shaped reinforcing frame 105 extending horizontally is fixed on the outer side of the bottom of the mounting bracket 1. The stability of the mounting bracket 1 for supporting the whole equipment is increased through the reinforcing frame 105.

[0035] As an alternative implementation, the outer end of the pressure-bearing cylinder 2 is fixedly connected to the output end of the motor 3 through a coupling. A driving rod 201 is coaxially arranged inside the pressure-bearing cylinder 2. One end of the driving rod 201 away from the motor 3 passes through the pressure-bearing cylinder 2, and a knob 204 is fixed to the outer end of the driving rod 201. The pressure-bearing cylinder 2 is a hollow cylindrical structure. Four groups of horizontally extending restraint grooves 202 are arranged around both ends of the pressure-bearing cylinder 2. Two groups of restraint sheets 203 are arranged horizontally and side by side at both ends inside the pressure-bearing cylinder 2. The restraint sheets 203 are in a "cross" shape. Four sides of the restraint sheets 203 pass through the four groups of restraint grooves 202 respectively, and the restraint sheets 203 are in horizontal sliding fit with the restraint grooves 202. Two groups of external threads 201a with opposite helix directions are arranged on the outer sides of both ends of the driving rod 201 inside the pressure-bearing cylinder 2. The driving rod 201 is in threaded fit with the two groups of restraint sheets 203 through the two groups of external threads 201a. When it is necessary to restrain the test tube body 5 with different width dimensions to maintain the rotational wear stability of the test tube body 5, the annular test tube body 5 to be tested is sleeved between the tensioning roller 4 and the pressure-bearing cylinder 2. The test tube body 5 to be tested is supported downward by the tensioning roller 4 to make it tightened into a cam shape. At this time, the knob 204 is rotated to drive the driving rod 201 to rotate inside the pressure-bearing cylinder 2. The two groups of restraint sheets 203 are driven to slide reversely along the restraint grooves 202 by using the two groups of external threads 201a with opposite helix directions, so as to adjust the distance between the two groups of restraint sheets 203, and support both sides of the test tube body 5 with different width dimensions through the two groups of restraint sheets 203, ensuring the position stability of the textile tube as the test tube body 5 during the rotational wear test;

[0036] The auxiliary component 7 includes a square funnel-shaped storage hopper 701 fixed to the side of the mounting frame 1. A transfer cover 702 is vertically communicated with the bottom opening of the storage hopper 701. The storage hopper 701 is used to store the dust for simulating the dusty environment. The two ends of the top of the detection frame 6 are respectively fixed to the front and rear sides outside the transfer cover 702. A auxiliary cylinder 704 for closing the bottom opening of the transfer cover 702 is horizontally arranged at the bottom of the transfer cover 702. A transmission rod 703 is coaxially fixed in the middle of the auxiliary cylinder 704, and the auxiliary cylinder 704 is rotationally matched with the transfer cover 702 through the transmission rod 703. A transmission belt pulley 302 is fixed at one end of the transmission rod 703 close to the mounting frame 1. A driving pulley 301 is fixed outside the middle of the output end of the motor 3. A transmission belt 302 is connected between the driving pulley 301 and the transmission belt pulley 302 to ensure that while the pressure-bearing cylinder 2 rotates, the auxiliary cylinder 704 is synchronously driven to rotate by the transmission belt 302. Accommodation cavities 705 are arranged on both the upper and lower sides of the auxiliary cylinder 704. The opening of the accommodation cavity 705 extends horizontally to the end of the auxiliary cylinder 704 away from the transmission belt 302, and the accommodation cavity 705 is communicated with the transfer cover 702, ensuring that the dust inside the transfer cover 702 can alternately fall into the two groups of accommodation cavities 705 during the rotation of the auxiliary cylinder 704, and then discharging the dust downward during the up-and-down alternating rotation of the two groups of accommodation cavities 705, so as to simulate the wear action of the textile tube in the dust-accumulated state. Limiting plates 706 for closing the accommodation cavity 705 are horizontally slidably matched inside the two groups of accommodation cavities 705. The outer side of the limiting plate 706 is flush with the outer circumferential side of the auxiliary cylinder 704 to ensure that the limiting plate 706 can be slid into the accommodation cavity 705 to adjust the space of the accommodation cavity 705. Synchronous rings 707 are vertically connected to the ends of the two groups of limiting plates 706 away from the transmission belt pulley 302. A lead screw 708 is horizontally penetrated inside the synchronous ring 707. The lead screw 708 is in threaded cooperation with the synchronous ring 707. One end of the lead screw 708 is rotationally matched with the outer end of the auxiliary cylinder 704 through a thrust bearing, and a disc-shaped adjustment knob 709 is fixed at the other end of the lead screw 708. When it is necessary to adjust the space that can accommodate dust inside the two groups of accommodation cavities 705 and then adjust the falling speed of the dust, rotate the adjustment knob 709 at the outer end of the lead screw 708. By the threaded cooperation of the lead screw 708 and the synchronous ring 707, the synchronous ring 707 is driven by the lead screw 708 to drive the two groups of limiting plates 706 to slide in the accommodation cavity 705, so as to adjust the length of the limiting plate 706 inserted into the accommodation cavity 705, thereby changing the effective space that can store dust in the accommodation cavity 705, so as to change the falling speed of the dust under the condition that the rotation speed of the auxiliary cylinder 704 remains unchanged, and realizing the wear resistance performance detection process of the pipe to be detected under different dust collection degrees.

[0037] When it is necessary to detect the wear of the textile tube serving as the tube body 5 to be detected by adopting the above structure, the textile tube made of flexible material is sleeved between the tension roller 4 and the pressure-bearing cylinder 2. The spring 102a is used to move the slider 103 downward to drive the tension roller 4 to tighten the textile tube. Weights are placed in the tray 603 to provide a downward pressure to the support rod 601 and the friction head 602, ensuring that the bottom of the friction head 602 abuts against the outer surface of the top side of the textile tube. Then, the height position of the limit nut 605 on the support rod 601 is adjusted according to the required wear thickness, ensuring that the distance between the bottom side of the limit nut 605 and the proximity switch 604 is equal to the required wear thickness. At this time, the motor 3 is started to record the power-on time of the motor through the built-in controller of the motor. The output end of the motor 3 drives the pressure-bearing cylinder 2 to rotate, and the pressure-bearing cylinder 2 is used to support the rotation of the tube body 5 to be detected. At this time, the friction head 602 wears and consumes the outer side of the continuously rotating textile tube. When the wear thickness of the outer side of the textile tube reaches the preset thickness, at this time, the limit nut 605 moves downward synchronously with the support rod 601 and the friction head 602 by the same height as the wear thickness. The bottom side of the limit nut 605 contacts the proximity switch 604 at this time, so as to control the motor 3 to cut off the power through the proximity switch 604. According to the power-on time of the motor recorded by the built-in controller of the motor 3, the time required for this group of textile tubes to wear to the set thickness can be obtained, so as to detect whether the wear resistance performance of this textile tube meets the requirements;

[0038] The pressure-bearing cylinder 2 is arranged to cooperate with the tension roller 4 to support the tube body 5 to be detected, so as to use the tension roller 4 to tighten textile tubes of different sizes, thereby increasing the size range of textile tubes that the equipment can detect and improving the practicability;

[0039] At the same time, the limit nut 605 with adjustable position is set as a wear detection mark. During the detection process, the distance between the limit nut 605 and the proximity switch 604 is pre-adjusted as the wear thickness. When the wear reaches the preset wear thickness, the limit nut 605 moves downward with the support rod 601 and the friction head 602 to the position where it contacts the proximity switch 604, so as to automatically turn off the motor 3 to stop the wear process, which is convenient for the detection personnel to judge the wear resistance performance of the textile tube according to the working time of the motor 3 during the process of reaching the set wear thickness. The detection accuracy is higher and the practicability is strong;

[0040] Two groups of restraint pieces 203 with adjustable spacing are arranged on the pressure-bearing cylinder 2 as the rotation limit structure of the textile tube. Furthermore, the two sides of the tube body 5 to be detected with different width sizes are supported by the two groups of restraint pieces 203 to ensure the position stability of the textile tube serving as the tube body 5 to be detected during the rotation wear detection process;

[0041] During the rotation of the auxiliary cylinder 704 of the connected transfer hood 702, the dust inside the transfer hood 702 can alternately fall into the two sets of accommodating cavities 705, and then discharge the dust downward during the up-and-down alternating rotation of the two sets of accommodating cavities 705, so as to simulate the wear action of the textile tube in the dust accumulation state. Moreover, the length of the limiting plate 706 placed in the accommodating cavity 705 can be adjusted, so as to change the effective space for storing dust in the accommodating cavity 705, and change the falling speed of the dust under the condition that the rotation speed of the auxiliary cylinder 704 remains unchanged, so as to realize the wear resistance performance detection process of the pipe to be detected under different dust collection degrees.

[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
