DETAILED DESCRIPTION

[0053] The present invention is further described in detail below in conjunction with embodiments so that those skilled in the art can implement the invention with reference to the description.

[0054] It should be noted that, in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0055] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a continuous automatic pipe placing device on a row of support hangers 9, comprising a mobile trolley 1, the four wheels of the mobile trolley 1 are independently driven and independently steered, and the mobile trolley 1 is flexible and can meet complex construction conditions on site. The mobile trolley 1 is provided with:

[0056] Lifting mechanism 2;

[0057] A horizontal rotating mechanism 3, which is arranged above the lifting mechanism 2 and is transmission-connected to the lifting mechanism 2;

[0058] A pipe clamping mechanism 4, which is arranged above the rotating mechanism and is transmission-connected to the horizontal rotating mechanism 3;

[0059] A pipe storage rack 5, which is arranged on one side of the lifting mechanism 2;

[0060] The pipe conveying mechanism 6 is arranged between the pipe storage rack 5 and the pipe clamping mechanism 4 .

[0061] In this embodiment, the spacing between the rows of supports and hangers 9 that have been completed on site is generally 3-3.5m, and the length of each section of the pipe 8 is 6m. The pipe placing device can automatically deliver the 6-meter pipe 8 to the supports and hangers, adjust the angle of the pipe 8 by using the horizontal rotating mechanism 3, and automatically place the pipe 8 on the bracket in a narrow space by moving the mobile trolley 1 horizontally. Specifically, when the above-mentioned pipe placing device is used to continuously and automatically place pipes on the rows of supports and hangers 9, the following steps are included:

[0062] S1, such as Figure 1-Figure 3 As shown, a plurality of pipes 8 are placed horizontally side by side on the pipe storage rack 5, and the mobile trolley 1 is moved to the lower side of the row of support hangers 9. At this time, the pipes 8 are arranged along the length direction of the row of support hangers 9;

[0063] S2, the pipe 8 on the pipe storage rack 5 closest to the pipe conveying mechanism 6 enters the pipe conveying mechanism 6, and then is conveyed to the pipe clamping mechanism 4 through the pipe conveying mechanism 6 and clamped by it;

[0064] S3, such as Figure 6 As shown, the lifting mechanism 2 drives the horizontal rotating mechanism 3 to move upward, so that the pipe clamping mechanism 4 rises to the side of the row of support brackets 9;

[0065] S4, such as Figure 7-Figure 9 As shown, the horizontal rotating mechanism 3 drives the pipe clamping mechanism 4 to rotate horizontally, and the mobile trolley 1 cooperates with the horizontal movement. The four wheels of the mobile trolley 1 are independently driven and steered, which makes it easier for the mobile trolley 1 to horizontally and obliquely insert the pipe 8 into the support bracket. During the specific operation, according to the actual situation, the horizontal rotating mechanism 3 adjusts the angle of the pipe 8 on the pipe clamping mechanism 4 relative to the mobile trolley 1, and adjusts the moving direction of the mobile trolley 1. The mobile trolley 1 moves forward or backward, and gradually inserts the pipe 8 on the pipe clamping mechanism 4 horizontally and obliquely into one of the support brackets;

[0066] S5, such as Fig.10 As shown, the horizontal rotating mechanism 3 drives the pipe clamping mechanism 4 to rotate horizontally. After the pipe 8 on the pipe clamping mechanism 4 returns to its original direction, the moving trolley 1 moves along the length direction of the rows of supports and hangers 9, so that the pipe 8 on the pipe clamping mechanism 4 is located above at least two supports and hangers;

[0067] S6, the lifting mechanism 2 drives the horizontal rotating mechanism 3 to move downward until the pipe 8 on the pipe clamping mechanism 4 is placed on the support and hanger, the pipe clamping mechanism 4 releases the pipe 8, so that the pipe 8 falls on the row of support and hanger 9, and the lifting mechanism 2 drives the horizontal rotating mechanism 3 to move downward to the original position;

[0068] S7, such as Fig.11 As shown, S2-S6 are repeated to carry out the next pipe laying operation until all the pipes on the pipe storage rack 5 are moved to the rows of support hangers 9.

[0069] Preferably, as another embodiment of the present invention, the pipe storage rack 5 comprises:

[0070] The storage plate 51 has an upper end which is inclined downward near the side of the pipeline conveying mechanism 6;

[0071] The lifting unit is used to connect the storage plate 51 to the mobile vehicle 1. The lifting unit includes a plurality of vertically telescopic first telescopic cylinders 52, which are arranged at intervals on the mobile vehicle 1 and are connected to the lower end of the storage plate 51. Figure 2 As shown in , two rows of first telescopic cylinders 52 are provided, wherein the height of the first telescopic cylinders 52 in the row close to the pipe conveying mechanism 6 is always lower than the height of the first telescopic cylinders 52 in the row far from the pipe conveying mechanism 6, so that the side of the upper end of the storage plate 51 close to the pipe conveying mechanism 6 is tilted downward, and then during the operation of the lifting unit, the two rows of first telescopic cylinders 52 are synchronously extended and retracted to ensure that the side of the upper end of the storage plate 51 close to the pipe conveying mechanism 6 is tilted downward. When placing multiple pipes 8 on the pipe storage rack 5, the lifting unit first drives the storage plate 51 to move downward, lowers the height of the upper end of the storage plate 51, and reduces the difficulty of placing multiple pipes 8 on the storage plate 51.

[0072] Preferably, as another embodiment of the present invention, the pipeline transmission mechanism 6 includes:

[0073] A material guide frame 61, the upper end of which is inclined downward near the pipe clamping mechanism 4;

[0074] The pipe blocking member 62 is disposed between the material guide rack 61 and the pipe storage rack 5 and is connected to the moving trolley 1 via a second telescopic cylinder 63 that is vertically telescopic.

[0075] In this embodiment, after the multiple pipes 8 are placed on the storage plate 51, the lifting unit drives the multiple pipes 8 to move upward to the upper end of the guide rack 61 and not lower than the upper end of the guide rack 61, so that the pipes 8 on the storage plate 51 can roll onto the guide rack 61 under the action of gravity. Figure 2 As shown, the second telescopic cylinder 63 drives the pipe stopper 62 to move up and down. In the initial state, the pipe stopper 62 moves upward until the height of its upper end is higher than the height of the upper end of the pipe 8 on the storage plate 51, and the pipe 8 can be blocked by the pipe stopper 62, so that multiple pipes 8 are fixed on the storage plate 51. When the pipe 8 needs to be conveyed, the second telescopic cylinder 63 drives the pipe stopper 62 to move downward until the height of its upper end is flush with the storage plate 51. At this time, the pipe 8 on the pipe storage rack 5 loses the obstruction of the pipe stopper 62 and rolls toward the guide rack 61 under the action of gravity. When the pipe 8 closest to the pipe conveying mechanism 6 on the pipe storage rack 5 passes above the pipe stopper 62, the second telescopic cylinder 63 quickly drives the pipe stopper 62 to move upward to block the pipe 8 behind. The pipe 8 entering the guide rack 61 slides from the upper end of the guide rack 61 to the pipe clamping mechanism 4 and is fixed by the pipe clamping mechanism 4. Specifically, the pipe stopper 62 can be a plate body, or at least two stop rods arranged at intervals.

[0076] Preferably, as another embodiment of the present invention, the pipe clamping mechanism 4 comprises:

[0077] At least two groups of spaced-apart clamping assemblies, the clamping assemblies comprising:

[0078] The two oppositely disposed pipe clamps 41 have their sides away from each other connected to a third telescopic cylinder 42 . The third telescopic cylinder 42 is horizontally telescopic and connected to the horizontal rotating mechanism 3 .

[0079] In this embodiment, the two pipe clamps 41 and the horizontal rotating mechanism 3 together form a clamping cavity for clamping the pipe 8. In the initial state, Figure 4 As shown, the third telescopic cylinder 42 near the pipe conveying mechanism 6 is shortened to the shortest, ensuring that the pipe 8 dropped from the guide rack 61 can smoothly fall between the two pipe clamps 41, and then the third telescopic cylinder 42 near the pipe conveying mechanism 6 is extended, and the third telescopic cylinder 42 near the pipe conveying mechanism 6 can also be extended and retracted accordingly, and the two clamp the pipe 8 in the clamping cavity. When the pipe 8 dropped from the guide rack 61 enters the clamping cavity, it is necessary to drive the pipe clamping mechanism 4 to move downward in advance through the lifting mechanism 2 to lower the height of the pipe clamping mechanism 4, so as to ensure that the pipe 8 can roll into the clamping cavity, and at the same time, it will not touch the pipe clamp 41 near the pipe conveying mechanism 6.

[0080] In addition, in order to ensure the stability of the pipe 8 in the horizontal direction after it rolls into the clamping cavity, an elastic buffer mechanism is provided at the ends of the pipe clamps 41 that are close to each other, and the pipe 8 that rolls into the clamping cavity is buffered by the elastic buffer mechanism. Finally, under the action of the two third telescopic cylinders 42, the elastic buffer mechanisms on the two pipe clamps 41 are compressed to a stable state, thereby fixing the steel pipe in the clamping cavity.

[0081] Preferably, as another embodiment of the present invention, the horizontal rotation mechanism 3 comprises:

[0082] A base 31, wherein the pipe clamping mechanism 4 is arranged at the upper end of the base 31;

[0083] The upper end of the rotating truncated table 32 is connected to the lower end of the base 31 , and the lower end of the rotating truncated table 32 is connected to the lifting mechanism 2 .

[0084] In this embodiment, the rotating truncated table 32 drives the base 31 to rotate, thereby realizing the rotation of the pipe clamping mechanism 4 on the upper end of the base 31 and adjusting the angle of the pipe 8 fixed by the pipe clamping mechanism 4 .

[0085] Preferably, as another embodiment of the present invention, it also includes:

[0086] The horizontal moving mechanism 7 is arranged between the lifting mechanism 2 and the horizontal rotating mechanism 3, and is respectively connected to the two. The horizontal moving mechanism 7 drives the pipe clamping mechanism 4 to move along the length direction of the row of supports and hangers 9. The horizontal moving mechanism 7 can be a linear movement, such as a linear module for unidirectional movement, or a combination of linear movements in two directions, such as an xy axis module.

[0087] In this embodiment, by providing a horizontal moving mechanism 7, when the pipe 8 is obliquely inserted into the support bracket, the pipe 8 is driven to move by the horizontal moving mechanism 7, thereby reducing the pressure on the moving trolley 1 when the pipe 8 is obliquely inserted into the support bracket.

[0088] Preferably, as another embodiment of the present invention, a horizontal moving mechanism 7 is provided between the lifting mechanism 2 and the horizontal rotating mechanism 3 and is respectively connected to the two mechanisms, and the horizontal moving mechanism 7 drives the pipe clamping mechanism 4 to move along the length direction of the row of supports and hangers 9. After the pipe 8 on the pipe clamping mechanism 4 is restored to its original direction in S5, the moving trolley 1 does not move, and the horizontal moving mechanism 7 drives the pipe clamping mechanism 4 to move along the length direction of the row of supports and hangers 9.

[0089] Specifically, when the above-mentioned pipe placing device is used to automatically place pipes on the rows of support hangers 9, the following steps are included:

[0090] S1, such as Figure 1-Figure 3 As shown, a plurality of pipes 8 are placed horizontally side by side on the pipe storage rack 5, and the mobile trolley 1 is moved to the lower side of the row of support hangers 9. At this time, the pipes 8 are arranged along the length direction of the row of support hangers 9;

[0091] S2, the pipe 8 on the pipe storage rack 5 closest to the pipe conveying mechanism 6 enters the pipe conveying mechanism 6, and then is conveyed to the pipe clamping mechanism 4 through the pipe conveying mechanism 6 and clamped by it;

[0092] S3, such as Figure 6 As shown, the lifting mechanism 2 drives the horizontal rotating mechanism 3 to move upward, so that the pipe clamping mechanism 4 rises to the side of the row of support brackets 9;

[0093] S4, such as Figure 7-Figure 9 As shown, the horizontal rotating mechanism 3 drives the pipe clamping mechanism 4 to rotate horizontally, and the mobile trolley 1 cooperates with the horizontal movement. The four wheels of the mobile trolley 1 are independently driven and steered, which makes it easier for the mobile trolley 1 to horizontally and obliquely insert the pipe 8 into the support bracket. During the specific operation, according to the actual situation, the horizontal rotating mechanism 3 adjusts the angle of the pipe 8 on the pipe clamping mechanism 4 relative to the mobile trolley 1, and adjusts the moving direction of the mobile trolley 1. The mobile trolley 1 moves forward or backward, and gradually inserts the pipe 8 on the pipe clamping mechanism 4 horizontally and obliquely into one of the support brackets;

[0094] S5, such as Fig.10As shown, the horizontal rotating mechanism 3 drives the pipe clamping mechanism 4 to rotate horizontally. After the pipe 8 on the pipe clamping mechanism 4 returns to its original direction, the moving trolley 1 does not move, and the horizontal moving mechanism 7 drives the pipe clamping mechanism 4 to move along the length direction of the rows of supports and hangers 9, so that the pipe 8 on the pipe clamping mechanism 4 is located above at least two supports and hangers;

[0095] S6, the lifting mechanism 2 drives the horizontal rotating mechanism 3 to move downward until the pipe 8 on the pipe clamping mechanism 4 is placed on the support and hanger, the pipe clamping mechanism 4 releases the pipe 8, so that the pipe 8 falls on the row of support and hanger 9, and the lifting mechanism 2 drives the horizontal rotating mechanism 3 to move downward to the original position;

[0096] S7, such as Fig.11 As shown, S2-S6 are repeated to carry out the next pipe laying operation until all the pipes on the pipe storage rack 5 are moved to the rows of support hangers 9.

[0097] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
