[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] Example 1:

[0030] This embodiment provides a traction device for a full-circular needle beam trolley, which solves the technical problem in the prior art that full-circular needle beam trolleys are difficult to move at a constant speed. This novel traction device for a full-circular needle beam trolley is used to traction the full-circular needle beam trolley and the corresponding template on the rail 1. It includes a power mechanism 4 for outputting linear reciprocating motion and at least two rail clamping mechanisms 2 for clamping the rail 1, wherein:

[0031] The rail 1 is a structural member made of high manganese steel, and is fixedly installed at the center of the full-circle needle beam trolley needle beam.

[0032] The rail clamping mechanism 2 is installed on the rail 1, and a cross beam connecting hinge lug seat 3 for connecting the full-circle needle beam trolley and the formwork is detachably fixedly installed on the rail clamping mechanism 2. When the at least two rail clamping mechanisms 2 installed on the rail 1 are not clamped on the rail 1, the rail clamping mechanisms 2 can slide on the rail 1, and when the rail clamping mechanisms 2 are clamped on the rail 1, the rail clamping mechanisms 2 are pressed on the rail 1. When the rail clamping mechanisms 2 move on the rail 1, the cross beam connecting hinge lug seat 3 installed on the rail clamping mechanisms 2 moves synchronously, the cross beam connecting hinge lug seat 3 is connected with the full-circle needle beam trolley and the corresponding formwork, thereby driving the full-circle needle beam trolley connected with the cross beam connecting hinge lug seat 3 to move.

[0033] The power mechanism 4 is connected between the two rail clamping mechanisms 2 to drive the two rail clamping mechanisms 2 to move close to or away from each other. Thus, the movement of the two rail clamping mechanisms 2 is controlled by the linear reciprocating movement of the power mechanism 4, so as to ensure the stable movement of the full-circle needle beam trolley and increase the safety and reliability of the movement of the full-circle needle beam trolley.

[0034] Through the above structure, the rail clamping mechanism 2 is installed on the rail 1, and the two rail clamping mechanisms 2 are driven to move linearly by the power mechanism 4. In specific use, one of the rail clamping mechanisms 2 is first clamped on the rail 1, and the other rail clamping mechanism 2 is driven to move on the rail 1 by the power mechanism 4. Then, the first rail clamping mechanism 2 is loosened, the second rail clamping mechanism 2 is clamped, and the first rail clamping mechanism 2 is driven by the power mechanism 4. Thus, one cycle is completed, the two rail clamping mechanisms 2 and the power mechanism 4 move a distance, and the cross beam connecting hinge lug seat 3 installed on the rail clamping mechanisms 2 moves, the cross beam connecting hinge lug seat 3 is connected with the full-circle needle beam trolley and the corresponding formwork, thereby driving the full-circle needle beam trolley connected with the cross beam connecting hinge lug seat 3 to move. Through the linear reciprocating movement of the power mechanism 4, the novel full-circle needle beam trolley traction device provided in the embodiment can drive the full-circle needle beam trolley to move more stably, reduce the probability of violent shaking of the full-circle needle beam trolley, and reduce the safety hazard during the movement of the full-circle needle beam trolley.

[0035] An optional embodiment of the embodiment is as follows: the rail clamping mechanism 2 includes a mounting frame 21, a driving mechanism, and a pressing arm 23. The mounting frame 21 is slidably installed on the rail 1. The driving mechanism is installed in the mounting frame 21. One end of the pressing arm 23 is connected to the driving mechanism, and the middle part of the pressing arm 23 is hingedly connected to the mounting frame 21. The cross beam connecting hinge lug seat 3 and the power mechanism 4 are connected to the mounting frame 21.

[0036] The first state, the pressing arm 23 is rotated to the other end and is pressed on the rail 1 under the drive of the driving mechanism;

[0037] The second state, the pressing arm 23 is rotated to the other end and is separated from the rail 1 under the drive of the driving mechanism.

[0038] In this way, the pressing arm 23 installed on the driving mechanism is rotated by the setting of the driving mechanism, so as to achieve the purpose of pressing or releasing the rail 1. When the power mechanism 4 moves linearly, only one rail pressing mechanism moves, so as to achieve the purpose of movement.

[0039] An optional embodiment of the present embodiment is as follows: the driving mechanism is a hydraulic cylinder 22, the fixed end of the hydraulic cylinder 22 is bolted to the inner side wall of the mounting frame 21, and the telescopic end of the hydraulic cylinder 22 is hinged to one end of the pressing arm 23. In this way, the hydraulic cylinder 22 is set, and the middle part of the pressing arm 23 is hinged to the mounting frame 21. Therefore, when the telescopic end of the hydraulic cylinder 22 is extended, the pressing arm 23 installed on the telescopic end is driven to rotate downward until the other end of the pressing arm 23 is pressed on the rail 1. After the telescopic end of the hydraulic cylinder 22 is retracted, the pressing arm 23 is driven to rotate upward to release the rail pressing mechanism 2. As another embodiment of the present embodiment, the driving mechanism can also be a pneumatic cylinder.

[0040] An optional embodiment of the present embodiment is as follows: the other end of the pressing arm 23 is a working end, and the working end is provided with a first anti-skid part 5. In this way, the friction between the working end and the rail 1 is increased by the setting of the anti-skid part, so that the rail pressing mechanism 2 that needs to be pressed is more firmly pressed on the rail 1 when the power mechanism 4 moves linearly.

[0041] An optional embodiment of the present embodiment is as follows: both side walls of the rail 1 are provided with grooves 7, both sides of the mounting frame 21 are fixedly installed with protrusions 71 matched with the grooves 7, and the protrusions 71 are slidingly installed in the grooves 7. In this way, the mounting frame 21 is not easy to derail by the cooperation of the grooves 7 and the protrusions 71.

[0042] An optional embodiment of the present embodiment is as follows: the top surface of the protrusion 71 is provided with a second anti-skid part 6. In this way, the setting of the second anti-skid part 6 further prevents the mounting frame 21 from derailing.

[0043] Optionally, the first anti-skid part 5 and the second anti-skid part 6 are both anti-skid teeth, which make the friction between the working end of the pressing arm 23 and the upper surface of the rail 1 and between the protrusion 71 and the upper wing plate greater.

[0044] An optional embodiment of the present embodiment is as follows: the power mechanism 4 is a hydraulic cylinder, so that the hydraulic cylinder is provided, and the linear reciprocating motion is realized by the hydraulic cylinder, without transmission gap, and the motion is stable. As another embodiment of the present embodiment, the power mechanism 4 can also be a pneumatic cylinder or a linear reciprocating motor, and the like, as long as the mechanism can realize linear reciprocating motion.

[0045] The above merely describes the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
