Connected, or integrally connected; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediary, and it can be the internal communication of two components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention based on specific situations.
[0026] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0027] refer to Figure 1-5 , in an embodiment of the present invention, an installation and lifting device suitable for laying oil pipelines of different diameters includes a support frame 1, and a buffer pad 2 is installed at the lower end of the support frame 1 to reduce the shaking generated during the working process of the entire device. Universal wheels 22 are installed on the lower end of the buffer pad 2 to realize the movement of the whole device. A horizontal frame 7 is installed on the upper end of the support frame 1, and a guide block 5 is installed in the middle of the lower end of the horizontal frame 7. The guide block 5 includes a trapezoidal block 28 and slide block 29, the middle part of the lower end of the horizontal frame 7 is provided with a dovetail groove that cooperates with the trapezoidal block 28, so that the guide block 5 can move left and right along the horizontal frame, ensuring the straight line during the movement of the guide block 5 The middle part of the slider 29 is provided with a first threaded hole 30 cooperating with the screw rod 8, which is used to convert the linear motion of the screw rod 8 into the left and right linear motion of the guide block 5, and the middle part of the guide block 5 is equipped with a screw rod 8, the screw rod 8 left end is provided with left screw thread 26, and screw rod 8 right end is provided with right screw thread 27, and described screw rod 8 two ends are provided with the screw thread of different direction of rotation so that two guide blocks 5 move along the opposite direction, screw rod 8 left ends install There is a driving disc 4, and a driving handle 3 is installed on the left end of the driving disc 4, which is used to drive the driving disc 4 to rotate, so that the screw rod 8 rotates synchronously. The friction force between human hands, the lower end of the guide block 5 is hinged with the first pull rod 9, the lower end of the first pull rod 9 is equipped with a lifting plate 11, and the inner side of the support frame 1 is provided with a lifting groove 16 that cooperates with the lifting plate 11, It is used to guide the up and down movement of the lifting plate 11 and avoid the left and right shaking of the lifting plate 11. The middle part of the lower end of the lifting plate 11 is equipped with a fixed cylinder 10. The limit groove 25 is used to guide the up and down movement of the hinged rod 24, preventing the lifting block 12 from rotating together with the screw rod 14. The screw rod 14 is installed inside the fixed cylinder 10, and the upper end of the screw rod 14 is connected to Drive motor 6 is arranged, is used to drive screw mandrel 14 to rotate, and drive motor 6 is installed in the middle part of lifting plate 11 upper end, and screw mandrel 14 middle part is equipped with lifting block 12, and the middle part of described lifting block 12 is provided with screw mandrel 14 mutual cooperation.
