Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe impact, in particular to a plastic pipe impact testing machine. Background Art

[0002] Plastic pipes are generally made of plastic resin as raw material, stabilizers, lubricants, etc., and are extruded in a pipe making machine by the method of "plasticization". With the acceleration of my country's urbanization, the government has increased its investment in urban infrastructure construction, and the construction of supporting urban pipe networks has developed rapidly. Various types of plastic pipes, including PE, PP-R, PVC-U municipal water supply and drainage, building water supply and drainage, electrical cable sheath pipes, etc., are widely used due to their low material density, corrosion resistance, and long service life. However, in the production process of pipes, or in the acceptance process of products, it is necessary to sample and test the products to ensure that the compression and impact resistance of plastic pipes meet the requirements. For the detection of plastic pipes, an impact hammer is generally used for impact. First, the plastic pipe is placed inside the machine and then impacted. In the prior art, due to the different sizes of plastic pipes, the plastic pipes cannot be stably fixed. This leads to the impact deviation during the impact process because the plastic pipe is not firmly fixed and rolls inside the chassis, thereby damaging the machine. Therefore, it is necessary to improve and optimize it. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model starts the hydraulic cylinder, and the output shaft of the hydraulic cylinder is extended and retracted to drive the rack 1 to slide left and right, the rack 1 drives the gear 1 to rotate, the gear 1 drives the connecting rod to rotate so that the two-way threaded rod rotates, and the rotation of the two-way threaded rod drives the two sliders to move relative to each other, so that the two clamping arms move relative to each other to clamp the plastic pipe. Compared with the traditional device, this arrangement enables the machine to fix plastic pipes of different specifications and sizes, thereby avoiding the easy rolling of the plastic pipes that are not fixed, resulting in the impact hammer not being able to play a good role during the impact process, and even causing damage to the machine due to the offset of the knocking. The mechanism ensures that the impact hammer can act on the target position accurately and without offset when impacting the plastic pipe, thereby improving the test accuracy and quality, and at the same time, avoiding the impact offset caused by unstable clamping, and reducing the risk of equipment damage or personal injury caused by uncontrolled impact force.

[0016] 2. The utility model moves the I-shaped block upward, and the I-shaped block drives the fixed plate and the impact hammer to move upward together. When the I-shaped block is located inside the fixed box, the sensor is triggered, and the sensor starts the motor 1 through the control console. The motor 1 drives a series of accessories to cooperate with each other, so that the sliding block fits the shape of the I-shaped block, so that the I-shaped block, the fixed plate and the impact hammer are fixed. After the plastic pipe is fixed, it only needs to trigger the sensor again through the control console, and the sensor drives the motor 1 to operate again, so that the sliding block does not fit the I-shaped block, and the I-shaped block is released under the action of gravity, so that the impact hammer can hit the plastic pipe. Compared with traditional devices, the impact hammer is firmly fixed at a high place through the shape fit. In traditional devices, the fixation of the impact hammer often relies on simple mechanical locking or gravity suspension. These methods are prone to failure after long-term use or when facing external vibration and impact, causing the impact hammer to fall accidentally, causing equipment damage or even personal injury. In this system, the shape of the sliding block and the I-block is precisely fitted to achieve the firm fixation of the impact hammer at a high place. This design greatly reduces the risk of accidental falling due to machine aging, vibration or external force, and ensures the safe progress of production operations.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 7As shown, the utility model provides a plastic pipe impact testing machine, including an impact box 1, a partition 2 is fixedly installed inside the impact box 1, two clamping arms 4 are slidably installed on the top of the partition 2, sliders 5 are fixedly installed on the bottom of the two clamping arms 4, two sliders 5 are threadedly sleeved with bidirectional threaded rods 7 in the middle parts and the bidirectional threaded rods 7 pass through the two sliders 5, a connecting rod 9 is fixedly installed on the left side of the bidirectional threaded rod 7, a gear 10 is fixedly installed on the left side of the connecting rod 9, a rack 11 is slidably installed on the bottom of the gear 10 and the rack 11 is meshed with the gear 10, a hydraulic cylinder 12 is fixedly installed on the left side of the rack 11, and the hydraulic cylinder 12 is fixedly installed on the left side of the impact box 1.

[0027] The staff places the plastic pipe on the top of the partition 2 and starts the hydraulic cylinder 12. The output shaft of the hydraulic cylinder 12 is extended and retracted to drive the rack 11 to slide left and right. The sliding of the rack 11 left and right makes the limit slider 14 slide left and right inside the rack limit groove 13. The rack 11 is meshed with the gear 10 to drive the gear 10 to rotate. The gear 10 drives the connecting rod 9 to rotate. The connecting rod 9 drives the bidirectional threaded rod 7 to rotate. The rotation of the bidirectional threaded rod 7 drives the two sliders 5 to move relative to each other. The relative movement of the two sliders 5 drives the two clamping arms 4 to move relative to each other to clamp the plastic pipe.

[0028] By starting the hydraulic cylinder 12, the output shaft of the hydraulic cylinder 12 is extended and retracted to drive the rack 11 to slide left and right, the rack 11 drives the gear 10 to rotate, the gear 10 drives the connecting rod 9 to rotate so that the two-way threaded rod 7 rotates, and the rotation of the two-way threaded rod 7 drives the two sliders 5 to move relative to each other, so that the two clamping arms 4 move relative to each other to clamp the plastic pipe. Compared with the traditional device, this setting allows the machine to fix plastic pipes of different specifications and sizes, thereby avoiding the easy rolling of the plastic pipe when it is not fixed, resulting in the impact hammer 19 not being able to play a good role during the impact process, and even causing damage to the machine due to the offset of the knocking. The mechanism ensures that the impact hammer 19 can act on the target position accurately and without offset when impacting the plastic pipe, thereby improving the test accuracy and quality. At the same time, it avoids the impact offset caused by unstable clamping and reduces the risk of equipment damage or personal injury caused by uncontrolled impact force.

[0029] Among them, two sliding columns 16 are fixedly installed on the top of the impact box 1, and a fixed plate 18 is slidably sleeved on the outer surface of the two sliding columns 16. An impact hammer 19 is fixedly installed in the middle of the fixed plate 18 and the impact hammer 19 penetrates the fixed plate 18 upward. A fixed box 17 is fixedly installed on the top of the fixed plate 18, and an I-shaped block 20 is fixedly installed on the top of the impact hammer 19. The I-shaped block 20 is slidably installed inside the fixed box 17, and two racks 22 are slidably installed on the inner bottom surface of the fixed box 17. A gear 23 is rotatably installed at the relative position of the two racks 22 and the gear 23 is meshed with the two racks 22. Sliding blocks 21 are fixedly installed on the top of the two racks 22, and the two sliding blocks 21 are respectively slidably installed on both sides of the I-shaped block 20.

[0030] The worker moves the I-shaped block 20 upward, and the I-shaped block 20 drives the impact hammer 19 and the fixed plate 18 to move upward together, and puts the I-shaped block 20 into the fixed box 17, triggering the sensor 28. The sensor 28 starts the motor 1 25 through the control of the console 32, and the output shaft of the motor 1 25 drives the gear 2 23 to rotate. The gear 23 is meshed with the two racks 22, driving the two racks 22 to slide on the inner bottom surface of the fixed box 17, and the two racks 22 drive the two sliding blocks 21 to slide, and the two sliding blocks 21 slide The shape of the I-shaped block 20 is adapted to fit the shape of the I-shaped block 20, so that the I-shaped block 20 is fixed inside the fixing box 17. At this time, the plastic pipe is placed on the top of the partition 2 and fixed, and the sensor 28 is triggered through the control console 32. The sensor 28 makes the motor 25 rotate, and the motor 25 drives a series of accessories to operate again to drive the sliding block 21 to slide, so that the sliding block 21 does not fit the shape of the I-shaped block 20, so that the impact hammer 19 drives the fixing plate 18 and the I-shaped block 20 to move downward together due to gravity, thereby impacting the plastic pipe.

[0031] By moving the I-shaped block 20 upward, the I-shaped block 20 drives the fixed plate 18 and the impact hammer 19 to move upward together. When the I-shaped block 20 is located inside the fixed box 17, the sensor 28 is triggered. The sensor 28 starts the motor 25 through the control console 32. The motor 25 drives a series of accessories to cooperate with each other, so that the sliding block 21 fits the shape of the I-shaped block 20, so that the I-shaped block 20 is fixed together with the fixed plate 18 and the impact hammer 19. After the plastic pipe is fixed, it only needs to trigger the sensor 28 again through the control console 32, and the sensor 28 drives the motor 25 to operate again, so that the sliding block 21 does not fit with the I-shaped block 20, and the I-shaped block 20 is released under the action of gravity. Block 20 enables the impact hammer 19 to impact the plastic pipe. Compared with the traditional device, the impact hammer 19 is firmly fixed at a high place through the shape fit. In the traditional device, the fixation of the impact hammer often relies on simple mechanical locking or gravity suspension. These methods are prone to failure when used for a long time or facing external vibration and impact, causing the impact hammer to fall accidentally, causing equipment damage or even personal injury. In the present system, the sliding block 21 is precisely fitted with the shape of the I-block 20, so that the impact hammer 19 is firmly fixed at a high place. This design greatly reduces the risk of accidental falling due to machine aging, vibration or external force, and ensures the safe progress of production operations.

[0032] Among them, a partition 2 3 is fixedly installed inside the impact box 1, a clamping groove 6 is opened in the middle of the partition 1 2 and the clamping groove 6 passes through the partition 1 2, the slider 5 is slidably installed inside the clamping groove 6, and the partition 2 3 is fixedly installed at the bottom of the hydraulic cylinder 12.

[0033] By providing the partition 23, the hydraulic cylinder 12 can operate stably, which not only provides a stable supporting platform for the hydraulic cylinder 12, but also effectively reduces the interference of the external environment on the stability of the hydraulic cylinder operation through its structural separation effect. The cooperation between the rack 11 and the limit slider 14 can keep the rack 11 running in a straight line. By providing the clamping groove 6, the clamping arm 4 can perform stable and efficient clamping, ensuring the linearity and stability of the rack during movement. This design eliminates the error caused by rack offset or shaking.

[0034] Among them, a rack limiting groove 13 is opened on the top of the partition 2 3 and the rack limiting groove 13 passes through the partition 2 3, and a limiting slider 14 is slidably installed inside the rack limiting groove 13, and the limiting slider 14 is fixedly installed at the bottom of the rack 11.

[0035] By providing a rack limiting groove 13, a limiting slider 14 drives the rack 11 to slide inside the rack limiting groove 13, ensuring that the rack maintains linear motion during the sliding process. This precise guiding and limiting effect effectively eliminates the errors that may be caused by rack offset or shaking, thereby greatly improving the transmission accuracy and reducing the performance degradation and failure rate caused by wear.

[0036] Among them, the I-block fixing block 27, the motor fixing block 26 and the sensor 28 are fixedly installed on the inner top surface of the fixing box 17, the I-block fixing block 27 is fixedly installed on the top of the I-block 20, and the motor 1 25 is fixedly installed on the bottom of the motor fixing block 26. The output shaft of the motor 1 25 is fixedly connected to the gear 2 23, and two limit plates 24 are fixedly installed on the inner bottom surface of the fixing box 17.

[0037] By providing the I-block fixing block 27, when the I-block 20 enters the interior of the fixing box 17, the top of the I-block 20 touches the I-block fixing block 27 to trigger the sensor 28, so that the sensor 28 drives the motor 1 25 to run, ensuring that the impact hammer 19 is fixed and released at the right time and position, and the start of the motor 1 25 drives the sliding block 21 to fit the shape of the I-block 20 to fix the I-block 20. By providing the limiting plate 24, the rack 22 drives the sliding block 21 to slide. The setting of the limiting plate 24 ensures that the sliding block 21 does not fit the I-block 20 due to excessive movement during the sliding process. This setting avoids the accidental falling off of the impact hammer 19 caused by the sliding block 21 not fitting the shape of the I-block 20. This safety measure effectively reduces the potential risks in the production process and ensures the safety of the operator.

[0038] Among them, a support column 15 is fixedly installed on the top of the impact box 1, and a set-top box 33 is fixedly installed on the top of the support column 15. A rope winding block 35 is rotatably installed on the inner bottom of the set-top box 33. A cable 34 is wound on the outer surface of the rope winding block 35. The cable 34 penetrates downward through the set-top box 33. A cable fixing sleeve 37 is fixedly installed on the bottom end of the cable 34. The cable fixing sleeve 37 is fixedly installed on the top of the fixing box 17, and a motor 2 36 is fixedly installed on the right side of the rope winding block 35.

[0039] By setting up the set-top box 33, the set-top box 33 ensures the stability of the operation of the motor fixing block 26. A rope winding block 35 is arranged inside the set-top box 33. The cable 34 wound on the outside of the rope winding block 35 is fixedly connected to the fixing box 17. When the motor 2 36 is running, the rope winding block 35 rotates so that the cable 34 is wound around the surface of the rope winding block 35, so that the fixing box 17 drives the fixing plate 18 and the impact hammer 19 to rise, thereby completing the impact. The start-up of the motor 2 36 can quickly drive the rope winding block 35 to rotate, thereby realizing the rapid winding of the cable 34. This process enables the fixing box 17 to quickly and smoothly drive the fixing plate 18 and the impact hammer 19 to rise or fall, greatly shortening the time for impact preparation and resetting, and significantly improving the overall operating efficiency.

[0040] The right side of the impact box 1 is provided with a pipe inlet 31 , the top of the impact box 1 is provided with an impact port 30 , the top of the impact box 1 is fixedly mounted with a buffer block 29 , and the buffer block 29 is fixedly sleeved on the bottom outer surface of the sliding column 16 .

[0041] By providing a pipe inlet 31, the plastic pipe is placed on the surface of the partition 2 through the pipe inlet 31 to be clamped, and by providing an impact port 30, the impact hammer 19 can accurately impact the plastic pipe through the impact port 30 during the falling process, and by providing a buffer block 29, it is avoided that the fixing plate 18 damages the top surface of the impact box 1 due to excessive impact force of the impact hammer 19. The introduction of the buffer block 29 is a key measure to protect the equipment from impact damage. When the impact hammer 19 impacts the plastic pipe with a large force, the impact force generated may be transmitted to the top surface of the impact box 1 through the fixing plate 18, causing potential structural damage, and the buffer block 29 can effectively absorb and disperse this part of the impact force, reduce the direct impact on the top surface of the impact box, thereby protecting the overall structure of the equipment from damage.

[0042] The right side of the impact box 1 is fixedly mounted with an electric wire 38 , and the right end of the electric wire 38 is fixedly mounted with a console 32 .

[0043] By providing a control console 32, which is connected to the impact box 1 via an electric wire 38, the staff only needs to perform simple operations on the control console 32 to control the overall operation of the impact box 1. The staff only needs to use simple buttons, knobs or touch screen interfaces to complete the start, stop, speed adjustment of the impact box 1, and the fixing and release of the impact hammer 19. This centralized control method greatly simplifies the operating process, reduces the operating difficulty, and improves the convenience of operation.

[0044] Among them, threaded rod limit blocks 8 are movably mounted on the outer surfaces of both ends of the bidirectional threaded rod 7, and the threaded rod limit blocks 8 are fixedly installed at the bottom of the partition 2, and rack limiters 39 are fixedly installed on both sides of the rack 11.

[0045] By starting the hydraulic cylinder 12, the hydraulic cylinder 12 drives a series of accessories to cooperate with each other. When the two-way threaded rod 7 rotates, the two sliders 5 move relative to each other, driving the two clamping arms 4 to move relative to each other. The threaded rod limit block 8 is provided to prevent the two sliders 5 from falling off the surface of the two-way threaded rod 7. By providing a rack limiter 39, the rack 11 is fully meshed with the gear 10, avoiding excessive movement of the rack 11 and failure to mesh with the gear 10, resulting in the clamping mechanism not operating. The setting of the rack limiter 39 ensures the stability of the clamping mechanism.

[0046] There are four support columns 15 , which are fixedly installed at the four corners of the top of the impact box 1 .

[0047] By providing four support columns 15, the set-top box 33 is firmly fixed, and the motor 2 36 inside the set-top box 33 can operate stably, driving the rope winding block 35 to rotate, so that the cable 34 is wound around the outer surface of the rope winding block 35, ensuring the smooth winding of the cable 34. Due to the establishment of the four support columns 15, damage caused by the tilting of the machine due to the impact hammer 19 being too heavy or the impact force being too large, is avoided.

[0048] The working principle and use process of this utility model:

[0049] The staff places the plastic pipe on the top of the partition 2 and starts the hydraulic cylinder 12. The output shaft of the hydraulic cylinder 12 is extended and retracted to drive the rack 11 to slide left and right. The sliding of the rack 11 left and right makes the limit slider 14 slide left and right inside the rack limit groove 13. The rack 11 is meshed with the gear 10 to drive the gear 10 to rotate. The gear 10 drives the connecting rod 9 to rotate. The connecting rod 9 drives the bidirectional threaded rod 7 to rotate. The rotation of the bidirectional threaded rod 7 drives the two sliders 5 to move relative to each other. The relative movement of the two sliders 5 drives the two clamping arms 4 to move relative to each other to clamp the plastic pipe.

[0050] The worker moves the I-shaped block 20 upward, and the I-shaped block 20 drives the impact hammer 19 and the fixed plate 18 to move upward together, and puts the I-shaped block 20 into the fixed box 17, triggering the sensor 28. The sensor 28 starts the motor 1 25 through the control of the console 32, and the output shaft of the motor 1 25 drives the gear 2 23 to rotate. The gear 23 is meshed with the two racks 22, driving the two racks 22 to slide on the inner bottom surface of the fixed box 17, and the two racks 22 drive the two sliding blocks 21 to slide, and the two sliding blocks 21 slide The shape of the I-shaped block 20 is adapted to fit the shape of the I-shaped block 20, so that the I-shaped block 20 is fixed inside the fixing box 17. At this time, the plastic pipe is placed on the top of the partition 2 and fixed, and the sensor 28 is triggered through the control console 32. The sensor 28 makes the motor 25 rotate, and the motor 25 drives a series of accessories to operate again to drive the sliding block 21 to slide, so that the sliding block 21 does not fit the shape of the I-shaped block 20, so that the impact hammer 19 drives the fixing plate 18 and the I-shaped block 20 to move downward together due to gravity, thereby impacting the plastic pipe.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
