DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] Referring to Figures 1-7 , the utility model provides an embodiment:

[0029] A synchronous pulley with driving transmission, including gantry machine 1, two rotating shafts 4 are arranged in the inside of gantry machine 1, two rotating blocks 3 are rotatably arranged in the inside of gantry machine 1, two first synchronous wheels 5 are arranged outside two rotating shafts 4, two fixed blocks 14 are fixedly arranged at the rear end of two first synchronous wheels 5, two clamping blocks 18 are slidably arranged in the inside of two rotating blocks 3, two unlocking blocks 15 are slidably arranged in the inside of two rotating blocks 3, the connecting rope 16 is fixedly arranged at two ends of two unlocking blocks 15, a plurality of connecting ropes 16 are fixedly arranged at the upper end of a plurality of clamping blocks 18, and a plurality of clamping blocks 18 are arranged in the inside of a plurality of fixed blocks 14.

[0030] Specifically, when disassembling the first synchronous wheel 5, the unlocking block 15 will slide inside the rotating block 3 by pulling the unlocking block 15. The movement of the unlocking block 15 will pull the clamping block 18 through the connecting rope 16, prompting it to slide inside the rotating block 3. The sliding of the clamping block 18 will squeeze the spring 17 connected to it, causing the spring 17 to contract inside the rotating block 3, thereby allowing the clamping block 18 to gradually disengage from the inside of the fixed block 14. When the clamping block 18 is completely disengaged from the inside of the fixed block 14, the connection between the first synchronous wheel 5 and the rotating block 3 can be released, thereby completing the disassembly operation. The disassembly operation is simple and fast, without the need for complex tools and steps, improving the maintenance efficiency of the equipment and reducing the maintenance cost and time.

[0031] With reference to Figures 1-5 , a plurality of guide blocks 10 are rotatably arranged inside the gantry machine 1. A synchronous track 9 is arranged inside the gantry machine 1. Two first synchronous wheels 5 are in meshing connection with the synchronous track 9. An electric telescopic rod 6 is fixedly arranged inside the gantry machine 1. A sliding block 12 is fixedly arranged at the output end of the electric telescopic rod 6. A second synchronous wheel 7 is rotatably arranged at the front end of the sliding block 12. The second synchronous wheel 7 is in meshing connection inside the synchronous track 9. A plurality of clamping blocks 18 have springs 17 fixedly arranged at the upper ends thereof. The upper ends of the plurality of springs 17 are fixedly arranged inside the two rotating blocks 3. A sliding groove 8 is arranged inside the gantry machine 1. The rear end of the sliding block 12 is slidably arranged outside the sliding groove 8. Two bolts 13 are threadedly connected to the front ends of the plurality of guide blocks 10. Sponge blocks 11 are sleeved outside the plurality of bolts 13. The synchronous track 9 is slidably arranged inside the plurality of guide blocks 10. A protection door 2 is hingedly arranged at the front end of the gantry machine 1.

[0032] Specifically, when adjusting the tension of the synchronous track 9, the electric telescopic rod 6 is activated to push the sliding block 12 to move smoothly along the sliding groove 8, the movement of the sliding block 12 synchronously drives the second synchronous wheel 7 to move, and since the second synchronous wheel 7 is closely meshed with the synchronous track 9, when the second synchronous wheel 7 moves, it directly adjusts the tension of the synchronous track 9, ensuring that the track always maintains appropriate tension, avoiding the decrease of transmission efficiency or damage to the equipment caused by insufficient or excessive tension. During the operation of the synchronous track 9, it will smoothly slide inside the multiple guide blocks 10 and contact the sponge block 11, which contains lubricating oil inside, not only can play a cleaning role for the synchronous track 9, removing dust and impurities on the surface, but also can provide certain lubrication effect, reduce the friction between the track and the guide block 10, reduce wear and tear, and the screw 13 facilitates the replacement and disassembly of the sponge block 11. At the same time, the multiple guide blocks 10 can accurately guide the movement of the synchronous track 9, ensuring its stable operation and avoiding the track deviating from the track. Through the cooperation of the electric telescopic rod 6 and the sliding block 12, the tension of the synchronous track 9 can be quickly adjusted to ensure stable operation of the transmission, reduce the risk of failure caused by improper tension, improve the reliability and service life of the equipment, and the protective door 2 hinged at the front end of the gantry machine 1 can be closed during operation to play a protective role and prevent accidental contact with the internal running parts.

[0033] Working principle: when adjusting the tension of the synchronous track 9, the electric telescopic rod 6 inside the gantry machine 1 is started to push the sliding block 12 to move along the sliding groove 8, the movement of the sliding block 12 synchronously drives the second synchronous wheel 7 to move, and since the second synchronous wheel 7 is meshed with the synchronous track 9, when it moves, it will adjust the tension of the synchronous track 9. When disassembling the first synchronous wheel 5, the operator pulls the unlocking block 15 to make the synchronous drive connecting rope 16 slide inside the rotating block 3, the sliding of the connecting rope 16 pulls the clamping block 18 to slide inside the rotating block 3 and press the spring 17, thereby making the clamping block 18 gradually separate from the fixed block 14. When the clamping block 18 completely separates from the fixed block 14, the separation of the first synchronous wheel 5 and the rotating block 3 is completed. When the synchronous track 9 is running, it will slide inside the multiple guide blocks 10 and contact the sponge block 11. The sponge block 11 inside contains lubricating oil, which can play a certain cleaning and lubricating effect on the synchronous track 9, and the multiple guide blocks 10 can guide the movement of the synchronous track 9 to ensure its stable operation.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
