Symmetrical foot screws are fixedly connected to the top of the base, a knob is fixedly connected to the outer wall of the foot screws, a support plate is fixedly connected to the top of the foot screws, a spirit level is fixedly connected to one side of the support plate, the top of the support plate is connected to the detection table, and a placement groove is opened on the top of the detection table; for this compressive strength detection device for polyethylene composite pipes, by rotating the knob and observing the spirit level located on one side of the support plate, when the bubble inside the spirit level is in the central position, it indicates that the detection table of the device is in a horizontal state. At this time, the staff can place the polyethylene composite pipe to be detected on the detection table to perform compressive strength detection on the polyethylene composite pipe. The advantage of this setting is that it can further improve the accuracy of the detection data of the device.

This may lead to misjudgment of the compressive strength of the pipe, thereby affecting subsequent safety assessments and decisions.

Detailed implementation manners

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0024] As Figure 1 shown, a compressive strength detection device for a polyethylene composite pipe includes a support 1. A hydraulic rod 2 is fixedly installed at the top end of the support 1. The output end of the hydraulic rod 2 extends out of the bottom end of the top of the support 1. A pressing block 3 is fixedly installed at the output end of the hydraulic rod 2. A limiting structure 4 is fixedly installed at the top end of the bottom of the support 1. A monitoring structure 5 is fixedly installed at the front and rear of the limiting structure 4.

[0025] By setting the limiting structure 4, the pipeline is limited by the two inclined plane rods 49, thereby avoiding the rotation of the pipeline during the compressive strength detection, which in turn affects the detection process. After the detection is completed, under the reset action of the elastic telescopic rod 47, the sliding rod 46 slides upward on the top of the slider 45, thereby causing the inclined plane rod 49 to slide upward, thereby lifting the inclined plane rod 49, thereby lifting the pipeline, and thereby achieving the effect of facilitating the removal of the pipeline.

[0026] As Figure 2As shown in the figure, the limiting structure 4 includes two first sliding grooves 41, which are respectively opened at the left and right positions at the top end of the bottom of the bracket 1. The rear ends of the two first sliding grooves 41 are rotatably connected with a bidirectional lead screw 42. The front end of the bottom of the bracket 1 is fixedly installed with a transmission assembly 44. The transmission assembly 44 includes a protective shell, a transmission belt and two transmission gears. The outer walls of the two transmission gears are meshed with the inner wall of the transmission belt. The transmission belt and the two transmission gears are both located inside the protective shell. The left part of the front of the protective shell is fixedly installed with a motor 43, and the output end of the motor 43 is fixedly connected with the front end of the transmission gear on the left. The rear ends of the two transmission gears respectively extend into the two first sliding grooves 41, and the rear ends of the two transmission gears are respectively fixedly connected with the front ends of the two bidirectional lead screws 42.

[0027] By setting the bidirectional lead screw 42, the motor 43 drives the transmission assembly 44 to work, thereby driving the two bidirectional lead screws 42 to rotate, so that the sliders 45 at the front and rear positions slide towards each other, so that the two inclined rods 49 slide towards each other, so that the inclined rods 49 can be adjusted to a suitable spacing according to the pipe diameter.

[0028] As Figure 4 shown, two sliders 45 are symmetrically threadedly connected to the front and rear positions of the outer walls of the two bidirectional lead screws 42. The tops of the four sliders 45 are all slidably connected with a sliding rod 46. The top ends of the sliding rods 46 at the front and rear positions are fixedly connected with an inclined rod 49. The bottom ends of the four sliders 45 are all fixedly connected with an elastic telescopic rod 47. The output ends of the four elastic telescopic rods 47 are respectively fixedly connected with the bottom ends of the four sliding rods 46. The outer walls of the bottoms of the four sliding rods 46 are all fixedly connected with a limiting ring 48, and the outer walls of the four limiting rings 48 are respectively slidably connected with the inner walls of the tops of the four sliders 45.

[0029] By setting the sliding rod 46, after the compressive strength test is completed, under the reset action of the elastic telescopic rod 47, the sliding rod 46 slides upward on the top of the slider 45, so that the inclined rod 49 slides upward, so as to lift the inclined rod 49, so as to lift the pipe, so as to achieve the effect of facilitating the removal of the pipe.

[0030] As Figure 3 shown, a cavity 412 is opened inside the bottom of the bracket 1, and a through groove 410 is opened in the middle of the top end of the bottom of the bracket 1. The through groove 410 penetrates into the inside of the cavity 412. The bottom ends of the two inclined rods 49 are both fixedly connected with a traction rope 411. The bottom ends of the two traction ropes 411 both extend into the inside of the cavity 412. The bottom ends of the two traction ropes 411 are both fixedly connected with a round rod 416. An electric telescopic rod 414 is fixedly installed at the bottom of the cavity 412. The output end of the electric telescopic rod 414 is fixedly connected with a rectangular plate 415. Round rods 416 are fixedly connected to the front and rear sides of the rectangular plate 415. The outer walls of the two round rods 416 are respectively slidably connected with the inner walls of the two rings 413.

[0031] By setting the round rod 416 and the ring 413, and using the electric telescopic rod 414, the rectangular plate 415 is pulled downward, thereby causing the ring 413 to slide downward, and further causing the inclined rod 49 to slide down to fit the top end of the bottom of the bracket 1, so that the sliding rod 46 slides downward and contracts into the inside of the slider 45, thereby avoiding the problem of misalignment between the inclined rod 49 and the pipeline during the detection process.

[0032] As Figure 4 As shown in the figure, the monitoring structure 5 includes two threaded rods 51. The opposite surfaces of the two threaded rods 51 are respectively rotatably connected to the far sides of the two inclined rods 49. Limit rods 52 are fixedly connected to the left and right positions in the middle of the far sides of the two inclined rods 49. Top plates 53 are fixedly connected to the far sides of the front and rear limit rods 52. The middle parts of the two top plates 53 are respectively rotatably connected to the outer walls of the two threaded rods 51. The far ends of the two threaded rods 51 respectively extend out of the far sides of the two top plates 53. Handles 54 are fixedly connected to the far ends of the two threaded rods 51.

[0033] By setting the threaded rod 51, and using the electric telescopic rod 414, the rectangular plate 415 is pulled downward, thereby causing the ring 413 to slide downward, and further causing the inclined rod 49 to slide down to fit the top end of the bottom of the bracket 1, so that the sliding rod 46 slides downward and contracts into the inside of the slider 45, thereby ensuring the accuracy of the monitoring of the pipeline deformation.

[0034] As Figure 5 As shown in the figure, support plates 55 are threadedly connected to the outer walls of the two threaded rods 51. The left and right positions at the bottoms of the two support plates 55 are respectively slidably connected to the outer walls of the front and rear limit rods 52. Rectangular boxes 56 are fixedly connected to the tops of the two support plates 55. A number of second chutes 57 are opened at the tops of the two rectangular boxes 56. The bottoms of the front and rear second chutes 57 respectively penetrate through the closer sides of the two rectangular boxes 56. Push rods 58 are slidably connected to the inside of the second chutes 57. Push plates 59 are fixedly connected to the closer sides of the front and rear push rods 58. A pointer 510 is fixedly connected to the top of the push rod 58. A number of scale lines 511 are opened at the tops of the two rectangular boxes 56.

[0035] By setting the pointer 510 and the scale lines 511, when the pipeline deforms, the outer wall of the pipeline will expand to a certain extent in the front and rear directions, and thus will squeeze the push plate 59 placed on the outer wall of the pipeline, thereby causing the push plate 59 to push the push rod 58 to contract into the inside of the second chute 57, and further causing the pointer 510 to slide on the top of the rectangular box 56. At this time, the deformation condition of the pipeline can be judged by observing the displacement change of the pointer 510 on the scale lines 511, and further the compressive capacity of the pipeline can be judged in detail.

[0036] Working principle of the utility model: When in use, start the motor 43. The motor 43 drives the transmission component 44 to work, and then drives the two bidirectional lead screws 42 to rotate, thereby causing the sliders 45 at the front and rear positions to slide towards each other, and then causing the two inclined rods 49 to slide towards each other. During this process, the ring 413 slides on the outer wall of the round rod 416. After adjusting the inclined rods 49 to a distance suitable for the pipe diameter, use the electric telescopic rod 414 to pull the rectangular plate 415 downward, thereby causing the ring 413 to slide downward, and then causing the inclined rods 49 to slide downward to fit the top of the bottom of the bracket 1, causing the sliding rod 46 to slide downward and contract into the slider 45. At this time, the elastic telescopic rod 47 is in a compressed state. Then place the pipe between the two inclined rods 49. The outer wall of the bottom of the pipe is lapped with the top of the bottom of the bracket 1. The two inclined rods 49 limit the pipe, thereby preventing the pipe from rotating during the compressive strength test, which may affect the test process. Then rotate the handle 54, which drives the threaded rod 51 to rotate, and then adjusts the position of the rectangular box 56, keeping the push plate 59 in contact with the outer wall of the pipe while keeping the push plate 59 away from the rectangular box 56. Then start the hydraulic rod 2, causing the pressing block 3 to slide downward, thereby squeezing the outer wall of the pipe, and then realizing the compressive strength test operation. During the continuous pressing of the outer wall of the pipe, the pipe may deform. At this time, the outer wall of the pipe will expand to a certain extent in the front and rear directions, which will squeeze the push plate 59 lapped on the outer wall of the pipe, causing the push plate 59 to push the push rod 58 to contract into the second chute 57, causing the pointer 510 to slide on the top of the rectangular box 56. At this time, the deformation of the pipe can be judged by observing the displacement change of the pointer 510 on the scale line 511, and then the compressive strength of the pipe can be judged more carefully. After the compressive strength test is completed, use the hydraulic rod 2 to lift the pressing block 3, and at the same time drive the electric telescopic rod 414 to lift the rectangular plate 415. At this time, under the reset action of the elastic telescopic rod 47, the sliding rod 46 slides upward on the top of the slider 45, thereby causing the inclined rod 49 to slide upward, and then jacking up the inclined rod 49, and then jacking up the pipe, thereby achieving the effect of facilitating the removal of the pipe.
