Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a turntable locking mechanism and a steel pipe loosening machine. Background Art

[0002] The turntable of the steel pipe loosening machine needs to be locked during operation to prevent its rotation from affecting the loosening process. The current locking of the turntable is achieved through a screw jack and a hydraulic cylinder. The screw jack drives the turntable to rotate to the working angle and then self-locks. The hydraulic cylinder is used to eliminate the thread gap inside the screw jack. Since the screw jack has a large structure and can only be installed far away from the center of the frame, when the hydraulic cylinder applies force to the turntable, the screw jack vibrates greatly and the mechanism is easily damaged.

[0031] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0032] Example:

[0033] like Figures 1 to 3 As shown, according to the first aspect of an embodiment of the present application, a turntable locking mechanism is proposed, comprising: a first lifting beam 100; a first turntable 200, wherein the first turntable 200 is rotatably mounted on the first lifting beam 100; and a locking assembly 300, wherein the locking assembly 300 is arranged on the first lifting beam 100, and when the output end of the locking assembly 300 contacts the first turntable 200, the first turntable 200 is fixed relative to the first lifting beam 100.

[0034] A turntable locking mechanism provided in an embodiment of the present application includes a first lifting beam 100, a first turntable 200 and a locking assembly 300, wherein the first lifting beam 100 is installed on a steel pipe loosening machine, and the first lifting beam 100 can move along the height direction to achieve height adjustment of the components on the first lifting beam 100, and the first turntable 200 is rotatably installed on the first lifting beam 100, and the first turntable 200 rotates in a circle with a vertical center line as the axis. When it is necessary to lock the first turntable 200, the locking assembly 300 directly contacts the first turntable 200, and a force is applied thereto to stop the first turntable 200 from rotating, thereby locking the first turntable 200. The rotating disk 200 can be locked without setting up other components; the rotating disk 200 can be directly locked without other auxiliary structures, and compared with the prior art, the influence on the spiral elevator can be avoided to a great extent.

[0035] like Figures 1 to 3 As shown, in some examples, the locking assembly 300 includes: a hydraulic driver 310 , and an output direction of an output end of the hydraulic driver 310 is perpendicular to the axis of the first turntable 200 .

[0036] In this technical solution, the locking assembly 300 includes a hydraulic driver 310, wherein the output end of the hydraulic driver 310 can extend out of the main body of the hydraulic driver 310. It can be seen from the above content that the output direction of the output end of the hydraulic driver 310 is perpendicular to the axis of the first turntable 200. When the locking assembly 300 works to lock the first turntable 200, the output end of the hydraulic driver 310 extends toward the axis direction of the first turntable 200 until it contacts the side wall of the first turntable 200, applying pressure to the side wall of the first turntable 200. At the same time, friction is generated between the output end of the hydraulic driver 310 and the first turntable 200, thereby locking the first turntable 200 and no longer rotating.

[0037] Exemplarily, the hydraulic driver 310 is fixedly mounted on the upper end surface of the first lifting beam 100, and the output end of the hydraulic driver 310 is located on the side of the main body of the hydraulic driver 310. When the hydraulic driver 310 locks the first turntable 200, the output end of the hydraulic driver 310 extends from the side of the main body of the hydraulic driver until it contacts the first turntable 200, providing sufficient friction to the first turntable 200 to stop the first turntable 200 from rotating.

[0038] Exemplarily, two hydraulic drivers 310 may be selected but not limited to, and the two hydraulic drivers 310 are symmetrically fixedly connected to the upper end surface of the first lifting beam 100 with the first turntable 200 as the center, and the output ends of the two hydraulic drivers 310 face the first turntable 200.

[0039] like Figures 1 to 3 As shown, in some examples, the locking assembly 300 further includes a cushion block 320 , and the cushion block 320 is disposed between the output end of the hydraulic driver 310 and the first turntable 200 .

[0040] In this technical solution, the locking assembly 300 also includes a pad block 320 arranged between the output end of the hydraulic driver 310 and the first turntable 200. When the output end of the hydraulic driver 310 locks the first turntable 200, the pad block 320 can be arranged to avoid direct contact between the output end of the hydraulic driver 310 and the first turntable 200, which can greatly reduce the damage rate of the first turntable 200 and effectively save costs.

[0041] In some examples, the above-mentioned gasket block 320 is fixedly installed on the outer wall of the above-mentioned first turntable 200, and the gasket block 320 is fixedly installed on the outer wall of the first turntable 200 by bolts. When the first turntable 200 rotates, the gasket block 320 can be driven to rotate at the same time. When the gasket block 320 is damaged, the gasket block 320 can be separated from the first turntable 200 by removing the bolts, and then a new gasket block 320 can be replaced on the first turntable 200, thereby effectively reducing the damage rate of the first turntable 200.

[0042] Exemplarily, the pad 320 can be fixed to but not limited to the output end of the hydraulic driver 310. The pad 320 moves with the output end of the hydraulic driver 310. When the hydraulic driver 310 locks the first turntable 200, the output end of the hydraulic driver 310 simultaneously drives the pad 320 to move in the direction of the first turntable 200 until they make contact. The hydraulic driver 310 applies a force to the pad 320, and the pad 320 provides sufficient friction to the first turntable 200 to stop the first turntable 200 from rotating.

[0043] like Figures 1 to 3 As shown, in some examples, the outer wall of the first turntable 200 is formed with an annular inclined surface, the annular inclined surface is coaxial with the first turntable 200, and the cushion block 320 is disposed on the annular inclined surface.

[0044] like Figures 1 to 3 As shown, the outer wall surface of the cushion block 320 is an arc-shaped surface, and the arc-shaped surface is coaxial with the first rotating disk 200 .

[0045] In this technical solution, the outer wall surface of the cushion block 320 is an arc-shaped surface coaxially arranged with the first turntable 200, which can ensure that no matter to which angle the first turntable 200 is rotated, the contact distance between the output end of the hydraulic driver 310 and the cushion block 320 is the same, thereby ensuring that the hydraulic driver 310 can be stably locked when locking the first turntable 200.

[0046] like Figures 1 to 3 As shown, in some examples, the projection range of the cushion block 320 toward the hydraulic driver 310 is a first range, and the movable range of the output end of the hydraulic driver 310 is within the first range.

[0047] In this technical solution, it can be seen from the above content that the first range is the projection range of the cushion block 320 in the direction of the above-mentioned hydraulic driver 310, and the activity range of the output end of the hydraulic driver 310 is within the first range, which can ensure that the hydraulic driver 310 can always be in contact with the cushion block 320 during operation, thereby achieving the locking of the first turntable 200.

[0048] Comparative Example:

[0049] like Figure 4As shown, the locking mechanism of the prior art includes a second crossbeam 400, a second turntable 500 is rotatably mounted on the upper end surface of the second crossbeam 400, a spiral elevator 600 is rotatably mounted on the second crossbeam, an output end of the spiral elevator 600 is rotatably connected to the second turntable 500, an auxiliary block 700 is fixedly mounted on the side wall of the second turntable 500, and a hydraulic cylinder 800 is fixedly mounted on the second crossbeam 400. When working, the second turntable 500 is driven to rotate by the spiral elevator 600. When the second turntable 500 rotates, the auxiliary block 700 is also driven to rotate together. When it is necessary to lock the second turntable 500, the hydraulic cylinder 800 works, and its output end applies thrust to the auxiliary block 700. Under the action of the spiral elevator 600 and the hydraulic cylinder 800, the second turntable 500 can be locked. This state may cause damage to the spiral elevator 600.
