Description

Technical Field

[0001] This utility model relates to the field of pipeline straightening, specifically to a hydraulic breaker pipeline straightening device. Background Technology

[0002] Hydraulic breakers are widely used in metallurgy, mining, railways, highways, construction, municipal engineering, and housing development for mining, breaking, clearing, excavating, drilling, and demolishing hard materials such as rocks, concrete, tunnels, ladles, slag, frozen soil, ice, asphalt, cement pavements, bridge piers, and buildings. The power of a hydraulic breaker comes from the pressurized oil supplied by the pump station of an excavator or loader. To ensure a smooth supply of pressurized oil, the pipeline needs to be straightened to ensure unobstructed flow.

[0003] Currently, pressure straightening machines on the market do not yet meet market requirements in terms of straightening efficiency, straightening accuracy, reliability, and ease of use.

[0004] When existing pipeline straightening devices are used for straightening, they can easily cause the pipeline to be compressed into an inward state. During use, the liquid may become blocked, causing the hydraulic hammer to malfunction and the pipeline to become unusable.

[0005] Therefore, providing a hydraulic breaker pipeline straightening device that can tension the inside of the pipeline during pipeline straightening is a problem that this utility model urgently needs to solve. Utility Model Content

[0006] To address the aforementioned technical problems, the purpose of this utility model is to overcome the tendency of existing pipeline straightening devices to compress the pipeline into an inward state during straightening, leading to pipeline failure. Therefore, this invention provides a hydraulic breaker pipeline straightening device capable of tensioning the inside of the pipeline during straightening.

[0007] To achieve the above objectives, this utility model provides a hydraulic breaker pipeline straightening device. The device includes: a first frame, a second frame, a rotating ring, an inner tension block, a first drive mechanism, a second drive mechanism, a third drive mechanism, a straightening detection mechanism, and a straightening mechanism. The first frame and the second frame are arranged opposite each other at intervals. A rotating ring is rotatably arranged on the first frame and the second frame respectively. A plurality of inner tension blocks that can reciprocate toward their axial direction are arranged around the circumference of the rotating ring. A first drive mechanism for driving the reciprocating movement of the inner tension blocks is respectively arranged on one side of the first frame and one side of the second frame. The second drive mechanism is arranged on the first frame or the second frame for driving the rotating ring to rotate. The third drive mechanism is arranged on the side of the first frame or the second frame away from the second drive mechanism for driving the first drive mechanism on that side to move. The straightening mechanism is arranged above the inner tension block for straightening the pipeline sleeved on the inner tension block. The straightening detection mechanism is arranged on one side of the straightening mechanism for detecting whether the pipeline has been straightened.

[0008] Preferably, each rotating ring is coaxially surrounded by several first limiting sliders facing its axis, and the inner tension block is provided with first limiting grooves at opposite ends that are adapted to the first limiting sliders.

[0009] Preferably, the first driving mechanism includes a first linear motor and a driving rod. The first linear motor is respectively provided on one side of the first frame and the second frame, and a driving rod is provided at its output end. The outer end of the driving rod is tapered, and a driving block adapted to the driving rod is provided inside the inner tensioning block.

[0010] Preferably, the second drive mechanism includes: a first rotary motor and a drive gear. The first rotary motor is mounted on a first frame or a second frame, and its output shaft is coaxially mounted with a drive gear. A toothed block that meshes with the drive gear is arranged around the corresponding rotating ring.

[0011] Preferably, the third drive mechanism includes: a slide table, a second rotary motor, and a lead screw. The slide table is disposed on one side of the first frame or the second frame, and the first linear motor on that side is reciprocally disposed on the slide table along the length of the slide table. The second rotary motor is disposed on the slide table, and its output shaft is coaxially provided with a lead screw. The lead screw is threaded through the first linear motor and is rotatably disposed on the slide table.

[0012] Preferably, the straightening mechanism includes a second linear motor and a pressure column. The second linear motor is disposed above the inner tension block, and its output end is vertically oriented towards the inner tension block. The pressure column is disposed at the output end of the second linear motor.

[0013] Preferably, the calibration and testing mechanism includes: a mounting frame, a rotating frame, and an elastic scale. The mounting frame is disposed on one side of the inner tension block. The rotating frame is Z-shaped and its middle part is rotatably disposed on the mounting frame. The elastic scale is vertically disposed on one side of the mounting frame. The upper side of the lower end of the rotating frame is attached to the lower side of the pipeline, and the lower side of the higher end is connected to the output end of the elastic scale.

[0014] According to the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: This application activates the third drive mechanism to move the first drive mechanism on the side of the first frame or the side of the second frame away from the second drive mechanism to one side, then the pipeline is sleeved on the inner tensioning block, and then the third drive mechanism drives the first drive mechanism to reset. Then each first drive mechanism is activated to drive the inner tensioning block to move to tension the pipeline, and then the second drive mechanism is activated to drive any rotating ring to rotate, thereby driving the pipeline to rotate. During the rotation, the straightening detection mechanism will detect whether the pipeline needs to be straightened. When it is detected that straightening is needed, the straightening mechanism is activated to straighten the pipeline. Since the inner tensioning block tightens the inside of the pipeline, the straightening mechanism will not flatten or dent the pipeline, preventing the pipeline from being scrapped.

[0015] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figure 1 A hydraulic breaker pipeline straightening device, comprising: a first frame 1, a second frame 2, a rotating ring 3, an inner tensioning block 4, a first drive mechanism 5, a second drive mechanism 6, a third drive mechanism 7, a straightening detection mechanism 9, and a straightening mechanism 8. The first frame 1 and the second frame 2 are arranged opposite each other at intervals. A rotating ring 3 is rotatably arranged on the first frame 1 and the second frame 2 respectively. A plurality of inner tensioning blocks 4 are arranged around the circumference of the rotating ring 3, which can reciprocate toward their axial direction. The first frame 1 and the second frame 2 are respectively provided with... A first drive mechanism 5 is used to drive the inner tension block 4 to reciprocate. A second drive mechanism 6 is disposed on the first frame 1 or the second frame 2 to drive the rotating ring 3 to rotate. A third drive mechanism 7 is disposed on the side of the first frame 1 or the side of the second frame 2 away from the second drive mechanism 6 to drive the first drive mechanism 5 on that side to move. A straightening mechanism 8 is disposed above the inner tension block 4 to straighten the pipeline sleeved on the inner tension block 4. A straightening detection mechanism 9 is disposed on the side of the straightening mechanism 8 to detect whether the pipeline has been straightened.

[0027] This application activates the third drive mechanism 7 to move the first drive mechanism 5, located away from the first frame 1 or the second frame 2, to one side. Then, the pipeline is fitted onto the inner tension block 4. The third drive mechanism 7 then resets the first drive mechanism 5. Each first drive mechanism 5 is then activated to move the inner tension block 4 to tension the pipeline. The second drive mechanism 6 is then activated to rotate any rotating ring 3, thereby rotating the pipeline. During the rotation, the straightening detection mechanism 9 detects whether the pipeline needs straightening. When straightening is detected, the straightening mechanism 8 is activated to straighten the pipeline. Because the inner tension block 4 tensions the inside of the pipeline, the straightening mechanism 8 will not flatten or dent the pipeline, preventing the pipeline from being scrapped.

[0028] Reference Figure 4 Each rotating ring has several first limiting sliders 301 coaxially surrounding its 3rd circumference, and the inner tension block 4 is provided with first limiting grooves 401 at opposite ends that are adapted to the first limiting sliders 301.

[0029] In this application, each inner tensioning block 4 is reciprocally mounted on the corresponding first limit slider 301 via the first limit slide groove 401 to ensure that the inner tensioning block 4 can move stably and will not be misaligned.

[0030] Reference Figure 2 and Figure 4 The first driving mechanism 5 includes a first linear motor 501 and a driving rod 502. The first linear motor 501 is respectively provided on one side of the first frame 1 and the second frame 2, and the driving rod 502 is provided at its output end. The outer end of the driving rod 502 is tapered. The inner tension block 4 is provided with a driving block 402 adapted to the driving rod 502.

[0031] This application uses the first linear motor 501 to extend the drive rod 502, which in turn drives the inner tensioning block 4 to move toward the axis of the rotating ring 3 via the drive block 402 to tension the pipeline.

[0032] Reference Figure 3 The second drive mechanism 6 includes a first rotary motor 601 and a drive gear 602. The first rotary motor 601 is mounted on a first frame 1 or a second frame 2, and its output shaft is coaxially mounted with the drive gear 602. A tooth block 302 that meshes with the drive gear 602 is arranged around the corresponding rotating ring 3.

[0033] This application starts the first rotary motor 601 to drive the drive gear 602 to rotate, thereby driving any rotating ring 3 to rotate through the tooth block 302, and then driving the pipeline to rotate synchronously through the inner tension block 4.

[0034] Reference Figure 2 The third drive mechanism 7 includes a slide table 701, a second rotary motor 702, and a lead screw 703. The slide table 701 is disposed on one side of the first frame 1 or the second frame 2, and the first linear motor 501 on that side is reciprocally disposed on the slide table 701 along the length of the slide table 701. The second rotary motor 702 is disposed on the slide table 701, and its output shaft is coaxially disposed with the lead screw 703. The lead screw 703 is threaded through the first linear motor 501 and is rotatably disposed on the slide table 701.

[0035] This application activates the first linear motor 501 on this side to drive the drive rod 502 to retract, and then activates the second rotary motor 702 to drive the lead screw 703 to rotate, thereby moving the first linear motor 501 to the side so that the user can remove the pipe or insert the pipe into the inner tensioning block 4.

[0036] Reference Figure 2 The straightening mechanism 8 includes a second linear motor 801 and a pressure column 802. The second linear motor 801 is disposed above the inner tension block 4, and its output end is vertically oriented toward the inner tension block 4. The pressure column 802 is disposed at the output end of the second linear motor 801.

[0037] When the straightening and testing agency 9 detects that the pipeline needs to be straightened, the second linear motor 801 is started to drive the pressure column 802 to straighten the pipeline until the straightening and testing agency 9 detects that the pipeline does not need to be straightened.

[0038] Reference Figure 2 The calibration and testing mechanism 9 includes: a mounting frame 901, a rotating frame 902, and an elastic scale 903. The mounting frame 901 is located on one side of the inner tension block 4. The rotating frame 902 is Z-shaped and its middle part is rotatably mounted on the mounting frame 901. The elastic scale 903 is vertically mounted on one side of the mounting frame 901. The upper side of the lower end of the rotating frame 902 is attached to the lower side of the pipeline, and the lower side of the higher end is connected to the output end of the elastic scale 903.

[0039] This application activates the second drive mechanism 6 to drive the rotating ring 3 to rotate, thereby driving the pipeline to rotate through the inner tension block 4. When the pipeline needs to be straightened, the lower end of the rotating frame 902 will move downward, thereby driving its higher end to move upward, which in turn pulls the elastic scale 903. The value on the elastic scale 903 will change. When the change exceeds the threshold, it indicates that the pipeline still needs to be straightened.

[0040] When using the device provided by this utility model, the third drive mechanism 7 is activated to move the first drive mechanism 5 on the side of the first frame 1 or the side of the second frame 2 away from the second drive mechanism 6 to one side. Then, the pipeline is sleeved on the inner tensioning block 4. The third drive mechanism 7 then drives the first drive mechanism 5 to reset. Then, each first drive mechanism 5 is activated to move the inner tensioning block 4 to tension the pipeline. Then, the second drive mechanism 6 is activated to drive any rotating ring 3 to rotate, thereby driving the pipeline to rotate. During the rotation, the straightening detection mechanism 9 will detect whether the pipeline needs to be straightened. When it is detected that straightening is needed, the straightening mechanism 8 is activated to straighten the pipeline. Since the inner tensioning block 4 tightens the inside of the pipeline, the straightening mechanism 8 will not flatten or dent the pipeline, preventing the pipeline from being scrapped.

[0041] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0043] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
