[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0023] Example 1, as Figure 1 shown, a pipe grinding device for landscaping project construction includes a machine platform 1, a support frame 2 is fixedly connected to the upper end of the machine platform 1, an electric telescopic rod 6 is fixedly connected to the upper end of the support frame 2, the output end of the electric telescopic rod 6 penetrates through the upper end of the support frame 2 and extends to the lower end of the horizontal part of the support frame 2 and is fixedly connected to a grinding structure 5 that is slidably connected to the vertical part of the support frame 2, a clamping and supporting structure 4 is arranged in the middle of the upper end of the machine platform 1, and a control cabinet 3 is fixedly connected to the upper end of the machine platform 1.

[0024] It should be particularly noted that the above control cabinet 3 is a conventional control device in the prior art that can control the start, stop, forward and reverse operation of electromechanical equipment. This structure has been widely used in the prior art. In the present invention, only its function of controlling the operation of the equipment is utilized, and its internal structure, operation principle, wiring and control method will not be described in detail.

[0025] Furthermore, to realize the support for the pipeline, refer to Figure 2, the clamping and supporting structure 4 includes a driving motor 41 fixedly connected to the right end of the machine table 1. The output end of the driving motor 41 is fixedly connected with a first bidirectional threaded rod 42 rotatably connected to the inner cavity of the machine table 1. The outer surface of the first bidirectional threaded rod 42 is symmetrically threaded with two sliding brackets 43. The mutually approaching ends of the two sliding brackets 43 are respectively provided with clamping assemblies 45 distributed symmetrically. The mutually remote ends of the two clamping assemblies 45 are both provided with driving assemblies 46 located in the inner cavity of the support frame 2 and fixedly connected to the grinding structure 5. A support assembly 44 is arranged in the middle of the upper end of the machine table 1.

[0026] The rotation of the driving motor 41 drives the rotation of the first bidirectional threaded rod 42, thereby driving the sliding brackets 43 to approach or move away from each other, so as to adapt to the use of pipes of different lengths.

[0027] The support assembly 44 is mainly used to assist the driving motors 54 on both sides and the grinding assemblies 53 to support the pipe. At the same time, the cooperation of the clamping assemblies 45 and the grinding structure 5 is used to grind both sides of the pipe. After the grinding on both sides is completed, the driving assemblies 46 on both sides drive the clamping assemblies 45 to act to support the inner wall of the pipe following the action of the grinding structure 5, and the cooperation of the grinding structure 5 and the sliding brackets 43 is used to grind the surface of the pipe, and the action of the clamping assemblies 45 is used to prevent the pipe from shaking, improving the grinding accuracy and effect.

[0028] Further, to achieve the grinding of the pipe surface, refer to Figure 3 , the grinding structure 5 includes a support plate 51. Both the left and right ends of the support plate 51 are fixedly connected with support sliders 55 slidably connected to the inner surface of the support frame 2. The upper end of the support plate 51 is fixedly connected to the output end of the electric telescopic rod 6. The lower parts of the mutually approaching ends of the two support sliders 55 are jointly rotatably connected with a grooved threaded rod 52. A grinding assembly 53 is jointly arranged on the outer surface of the grooved threaded rod 52 and the lower end of the support plate 51. The upper end of the support plate 51 is fixedly connected with a driving motor 54 that is belt-driven to the grooved threaded rod 52. The lower end of the support slider 55 is fixedly connected to the upper end of the rack 462.

[0029] The electric telescopic rod 6 is used to drive the support plate 51 to rise or fall, so as to cooperate with the sliding brackets 43 to initially fix the pipe, and during the continuous downward pressing process, the two sides or the surface of the pipe are ground by the grinding assembly 53 or the clamping assemblies 45.

[0030] Further, to achieve the support of the pipe, refer to Figure 4The support assembly 44 includes a sliding plate 441 slidably connected to the upper end of the machine table 1, a compression spring 442 fixedly connected to the machine table 1 is fixedly connected to the lower end of the sliding plate 441, and rollers 443 fixedly connected to the upper end of the sliding plate 441 through a bearing bracket are symmetrically arranged at the front and rear ends of the compression spring 442. A driving motor 444 is fixedly connected to the middle part of the upper end of the sliding plate 441, and a driving shaft 445 is fixedly connected to the output end of the driving motor 444. The driving shaft 445 is connected to the rollers 443 on the front and rear sides through a transmission belt.

[0031] The cooperation between the sliding plate 441 and the compression spring 1 442 can adapt to the use of pipes of different sizes. At the same time, the roller 443 fits tightly with the lower part of the pipe. During the operation of the driving motor 2 444, the roller 443 can be driven to rotate through the action of the driving shaft 445 and the belt, thereby driving the pipe to rotate.

[0032] Embodiment 2: Based on embodiment 1, this embodiment realizes the grinding and support of both sides of the pipe through the cooperation of the clamping assembly 45 and the supporting assembly 44. At the same time, the driving assembly 46 is used to drive the clamping assembly 45 to open and support the inner wall of the pipe after the grinding structure 5 descends to a certain height, thereby ensuring that the pipe remains stable during the subsequent surface grinding process, improving the grinding effect, and reducing the displacement of the pipe caused by high-speed friction.

[0033] Specifically, to achieve grinding and support on both sides of the pipe, refer to Figure 4 The clamping assembly 45 includes a T-shaped base 451 that is slidably connected to the inner surface of the sliding bracket 43, and the end of the T-shaped base 451 and the sliding bracket 43 that are close to each other is fixedly connected with a compression spring three 452, and the end of the T-shaped base 451 away from the compression spring three 452 is provided with a clamping component 453 that is transmission-connected to the driving assembly 46.

[0034] The T-shaped base 451 is slidably connected to the sliding bracket 43. When the T-shaped base 451 contacts the surface of the pipe, the compression spring 452 is gradually compressed, so that the T-shaped base 451 always fits the surface of the pipe, thereby playing a role of preliminary support. Further, in order to realize the driving of the clamping assembly 45 following the descending height of the support plate 51, refer to Figure 5 The driving assembly 46 includes a telescopic transmission rod 461 that is transmission-connected to the clamping part 453. The outer surface of the telescopic transmission rod 461 is fixedly connected to the inner cavity of the support frame 2 with a worm gear 465. The upper part of the outer surface of the worm gear 465 is meshed with a worm 464 that is rotationally connected to the inner surface of the vertical part of the support frame 2. The middle part of the outer surface of the worm 464 is fixedly connected to a gear 463. The outer surface of the gear 463 is meshed with a rack 462 that is fixedly connected to the grinding structure 5.

[0035] In the initial state, the clamping part 453 is open. When the grinding structure 5 starts to descend until the grinding assembly 53 contacts the surface of the pipe and cooperates with the support assembly 44 to preliminarily fix the pipe, the rack 462 follows the grinding structure 5 to descend, thereby mobilizing the gear 463 to rotate, and through the action of the worm 464 and the worm wheel 465, the telescopic transmission rod 461 is mobilized to rotate, thereby driving the clamping assembly 45 to switch states.

[0036] Further, to achieve support for the inner wall of the pipe, refer to Figure 6 and Figure 7 The clamping component 453 includes a two-way threaded rod 4537 that is transmission-connected to the telescopic transmission rod 461. The outer surface of the two-way threaded rod 4537 is provided with a limit rod 4534 that is fixedly connected to the T-shaped base 451. The inner surface of the limit rod 4534 slides symmetrically and slides with a cross slider 4533 that is threadedly connected to the outer surface of the two-way threaded rod 4537. The outer surfaces of the two cross sliders 4533 are both annularly distributed and rotatably connected to a plurality of connecting rods 4532. The ends of the two connecting rods 4532 on the same central axis that are away from the cross slider 4533 are rotatably connected to an arc plate 4531 together. The outer arc surface of the arc plate 4531 is annularly distributed and rotatably connected to a plurality of rotating shafts.

[0037] The rotation of the telescopic transmission rod 461 will first drive the two-way threaded rod 4537 to rotate. During this process, the cross slider 1 4533 slides in the limit rod 4534. Since the thread directions of the two-way threaded rod 4537 are opposite within the range of the two cross sliders 1 4533, during this process, the cross slider 1 4533 will drive the connecting rod 1 4532 to change its inclination angle, thereby pushing the arc plate 4531 to expand outward until the arc plate 4531 fits against the inner wall of the pipe, supporting and fixing the inner wall of the pipe to reduce the position deviation of the pipe. At the same time, left and right rollers are provided on the outer surface of the arc plate 4531, which can fix the pipe without affecting the rotation of the pipe under the action of the support assembly 44.

[0038] Further, to achieve grinding on both sides of the pipe, refer to Figure 6 , Figure 7 and Figure 8 The clamping component 453 also includes a cross slider 4535 that is slidably connected to the inner surface of the limiting rod 4534 and is threadedly connected to the outer surface of the bidirectional threaded rod 4537. The outer surface of the cross slider 4535 is rotatably connected to a plurality of connecting rods 4538 in an annular distribution. The ends of the plurality of connecting rods 4538 away from the cross slider 4535 are rotatably connected to trapezoidal blocks 4539 that are slidably connected to the inner surface of the T-shaped base 451. The inner surface of the T-shaped base 451 is slidably connected to a plurality of grinding blocks 4536 that fit the wedge-shaped surfaces of adjacent trapezoidal blocks 4539 in an annular distribution.

[0039] In the initial state, the trapezoidal block 4539 is on the side of the grinding block 4536 away from the pipe. The grinding block 4536 is in contact with the inner wall of the pipe. At this time, the pipe is placed on the outer surface of the arc-shaped plate 4531. When the pipe rotates under the action of the support assembly 44, it will rub against the surface of the grinding block 4536, thereby synchronously grinding the two end faces of the pipe. During the movement of the cross slider one 4533, the cross slider two 4535 will slide synchronously in the limit rod 4534 in the direction away from the T-shaped base 451. At this time, the trapezoidal block 4539 is pulled out from the gap between the grinding block 4536 and the T-shaped base 451 under the action of the connecting rod two 4538. At this time, under the pressure of the compression spring three 452, the grinding block 4536 is pressed into the T-shaped base 451, and the T-shaped base 451 approaches the end face of the pipe until the arc-shaped plate 4531 is completely opened, and the T-shaped base 451 is in contact with the surface of the pipe, facilitating subsequent grinding of the pipe surface.

[0040] Embodiment 3: On the basis of Embodiment 2, this embodiment further utilizes the cooperation of the electric telescopic rod 6 and the support plate 51 to drive the grinding assembly 53 to move downward, thereby cooperating with the support assembly 44 to initially fix the surface of the pipe, and through the cooperation of the grinding assembly 53 and the driving assembly 46 during continuous downward pressing, the clamping member 453 is urged to support and fix the pipe until the lower part of the grinding installation box 531 is in contact with the surface of the pipe. Through the continuous action of the support plate 51 and the grooved threaded rod 52, the driving wheel 537 and the grinding sand belt 536 are driven to rub against the surface of the pipe at high speed, and the cooperation of the threaded ring 539 and the grooved threaded rod 52 is used to drive the grinding installation box 531 to move left and right on the surface of the pipe, thereby circularly grinding the surface of the pipe.

[0041] Specifically, to achieve the pressing and fixing of the pipe and cooperate with the sliding bracket 43 to grind both sides of the pipe, refer to Figure 9 and Figure 10 Both the front and rear ends of the grinding installation box 531 are slidably connected with side pressing blocks 532. The bottom walls of the inner surfaces of the two side pressing blocks 532 are fixedly connected with compression springs four 533 fixedly connected to the grinding installation box 531. The lower part of the side pressing block 532 close to the grinding installation box 531 is an arc surface, and a number of ball wheels 534 are rotatably connected to the arc surface part in a circular distribution.

[0042] During the descent of the support plate 51, the arc surface part of the side pressing block 532 will first contact the surface of the pipe and closely adhere to the surface of the pipe under the action of the compression spring four 533, cooperating with the lower support assembly 44 to initially clamp and support the pipe. At this time, the grinding assembly 53 is located in the middle of the pipe, that is, directly above the support assembly 44. At this time, the rotation of the support assembly 44 will drive the pipe to rotate, and the ball wheels 534 at the lower part of the side pressing block 532 will not affect the forward and backward rotation of the pipe. Further, to achieve the pressing and fixing of the pipe and the surface grinding, refer to Figure 9 and Figure 10 , the grinding assembly 53 includes a grinding installation box 531 slidably connected to the outer surface of the grooved threaded rod 52. The upper end of the grinding installation box 531 is slidably connected to the lower end of the support plate 51 through a pulley. Three driving wheels 537 are rotatably connected to the inner surface of the grinding installation box 531 in a triangular distribution. A grinding abrasive belt 536 is wound and connected to the outer surfaces of the three driving wheels 537. The driving wheel 537 located in the upper part is connected by a transmission belt to a pulley 538 rotatably connected to the inner cavity of the grinding installation box 531. The inner surface of the pulley 538 is connected to the outer surface of the grooved threaded rod 52 through a limiting block. A threaded ring 539 fixedly connected to the inner surface of the grinding installation box 531 is also threadedly connected to the outer surface of the grooved threaded rod 52.

[0043] When the support plate 51 continues to press down under the action of the electric telescopic rod 6, the compression spring four 533 will be gradually compressed, causing the grinding installation box 531 to move downward until the lower part of the grinding installation box 531 contacts the surface of the pipe. Then, the pulley 538 is driven to rotate by the action of the grooved threaded rod 52. Through the transmission between the pulley 538 and the driving wheel 537, the grinding abrasive belt 536 moves along the front and back trajectory on the surface of the pipe, and the surface of the pipe is ground during this process. At the same time, under the action of the support assembly 44, the pipe will also rotate, thereby grinding the circumferential surface of the circulating pipe; Synchronously, under the action of the threaded ring 539, the grinding installation box 531 will slide on the surface of the grooved threaded rod 52, thereby circularly grinding the surface of the pipe. At this time, the pipe cannot move left and right under the action of the clamping member 453, so the material will not shift due to grinding during the left and right circular grinding process.

[0044] Further, to achieve the recovery of the dust generated on the pipe surface due to grinding, refer to Figure 10 , a dust collector 535 is fixedly connected to the rear end of the side pressing block 532 located at the rear. Dust suction grooves 530 are symmetrically opened at the left and right of the lower end of the grinding installation box 531, and the dust suction grooves 530 are communicated with the dust collector 535 through a connecting pipe.

[0045] It should be particularly noted that the above dust collector 535 is a conventional dust suction device, which can suck the dust generated on the pipe surface due to grinding through the dust suction grooves 530, reducing the impact of the dust on the subsequent secondary grinding.

[0046] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
