The anti-slip components include a positioning sleeve 2, and the positioning sleeve 2 is fixedly connected to the upper side surface of the side of the support block 1. A rotating shaft 3 passes through the positioning sleeve 2. After the rotating shaft 3 passes through the positioning sleeve 2 and the support block 1, the bottom end of the rotating shaft 3 is connected to the anti-slip hook 4, and the anti-slip hook 4 is used to cooperate with the guide rail 5 to prevent the transportation device from detaching from the guide rail 5. The positioning sleeve 2 is provided with a first slide groove 6, and the bottom end of the first slide groove 6 is connected to the second slide groove 7. The first slide groove 6 is arranged along the axial direction of the positioning sleeve 2, that is, it is arranged vertically, and the second slide groove 7 is arranged along the circumferential direction of the positioning sleeve. The second slide groove 7 is perpendicular to the first slide groove 6. A countersunk hole is arranged on the top of the rotating shaft 3, and the countersunk hole is communicated with the third slide groove 8 arranged on the rotating shaft 3. The third slide groove 8 is arranged along the axial direction of the rotating shaft 3 and matches the first slide groove 6. A connecting piece is arranged in the countersunk hole, and an elastic piece is arranged between the connecting piece and the bottom surface of the countersunk hole. The connecting piece is fixed with a positioning pin 9, and the positioning pin 9 is arranged along the radial direction of the rotating shaft 3. The positioning pin 9 extends to the outside of the positioning sleeve 2 through the third slide groove 8 and the first slide groove 6. The anti-slip mechanism also includes an operating rod 10. The bottom end of the operating rod 10 is used to cooperate with the part of the positioning pin 9 extending to the outside of the positioning sleeve 2, so as to press the positioning pin 9 down and drive the positioning pin 9 to rotate.

[0030] Specific:

[0031] The support block 1 adopts a T-shaped structure, including a horizontal part and a vertical part fixed in the middle of the horizontal part. Both sides of the vertical part are provided with fixing holes 11. The vertical part can be fixed to the transportation device through the fixing holes 11 and fixing bolts, thereby achieving installation on the transportation device.

[0032] The horizontal parts on both sides of the vertical part are provided with anti-slip components, and the anti-slip components on both sides are symmetrically arranged relative to the center line of the vertical part. The anti-slip components on both sides have exactly the same structure. The anti-slip components on one side are taken as an example for explanation:

[0033] like Figure 2-Figure 3 As shown, the anti-slip assembly includes a positioning sleeve 2, which includes a cylindrical part and a flat plate part at the bottom end of the cylindrical part, the flat plate part is fixedly connected to the annular support plate 12, and the annular support plate 12 is fixed to the horizontal end of the support block 1 by bolts.

[0034] The cylindrical part of the positioning sleeve 2 is provided with a first slide groove 6, and the bottom 6 end of the first slide groove is connected to the second slide groove 7. In this embodiment, two first slide grooves 6 are provided, and two second slide grooves 7 are provided. The two first slide grooves 6 are relatively spaced 180° apart, and the two second slide grooves 7 are relatively spaced 180° apart.

[0035] The widths of the first sliding groove 6 and the second sliding groove 7 are both greater than the diameter of the positioning pin 9 , so that the positioning pin 9 can slide in the first sliding groove 6 and the second sliding groove 7 .

[0036] Furthermore, the central angle of the second sliding groove 7 is 90°, so that the anti-detachment hook 4 can rotate 90°.

[0037] One end of the second slide groove 7 is connected to the first slide groove 6, and the other end is provided with an upward bending portion, and the positioning pin 9 can enter the bending portion, so as to achieve locking of the anti-disconnection hook 4 from the state after rotating 90°.

[0038] The rotation shaft 3 passes through the positioning sleeve 2 , and the rotation shaft 3 passes through the positioning sleeve 2 , the annular support plate 12 and the horizontal part of the support block 1 in sequence, and the bottom end of the rotation shaft 3 is fixedly connected to the anti-disconnection hook 4 .

[0039] The rotating shaft 3 is rotatably connected to the positioning sleeve 2, the annular supporting plate 12 and the supporting block 1, and can rotate around its own axis.

[0040] Furthermore, in order to limit the position of the rotating shaft 3 along its axial direction, the inner side surface of the annular support plate 12 is provided with an annular protrusion, which is embedded in the annular groove provided on the axial surface of the rotating shaft 3 to achieve the limitation of the rotating shaft in its axial direction.

[0041] A countersunk hole is provided on the top surface of the rotating shaft 3, and a third slide groove 8 connected to the countersunk hole is provided on both sides of the countersunk hole. The two third slide grooves 8 are arranged at a relative interval of 180°. The two third slide grooves 8 are respectively used to cooperate with the two first slide grooves 6. The axis of the third slide groove 8 is arranged along the axial direction of the rotating shaft 3, that is, it is arranged vertically. The width of the third slide groove 8 is greater than the diameter of the positioning pin 9 to facilitate the positioning pin 9 to slide along the third slide groove 8. The bottom end of the third slide groove 8 extends to the connection position of the second slide groove 7 and the first slide groove 6, so that the positioning pin can enter the second slide groove 7.

[0042] A connecting piece is arranged in the countersunk hole. In the present embodiment, the connecting piece is a positioning nut 13. The axis of the positioning nut 13 is perpendicular to the axis of the rotating shaft 3. The positioning nut 13 is threadedly connected to two positioning pins 9. The two positioning pins 9 are coaxially arranged. The two positioning pins 9 respectively pass through the two third slide grooves 8 and the two first slide grooves 6 in sequence and then extend to the outside of the positioning sleeve 2.

[0043] In this embodiment, the inner end of the positioning pin 9 is provided with an externally threaded rod section, and the positioning pin 9 is threadedly connected to the positioning nut 13 via the externally threaded rod section.

[0044] An elastic member is provided between the positioning nut 13 and the bottom surface of the countersunk hole. The elastic member is a spring 14. One end of the spring 14 abuts against the bottom of the positioning nut 13, and the other end abuts against the bottom surface of the countersunk hole.

[0045] A limiting cap 15 is also provided at the top opening of the positioning sleeve 2. The limiting cap 15 adopts a limiting bolt. The limiting bolt is threadedly connected to the countersunk hole at the top of the rotating shaft 3. The bottom surface of the rod cooperates with the top of the positioning nut 13 to limit the movement of the positioning nut 13 away from the bottom surface of the countersunk hole, that is, upward. A washer is provided between the head of the limiting bolt and the top surface of the positioning sleeve 2.

[0046] Furthermore, a guide wheel 16 is rotatably connected to the shaft section of the rotating shaft 3 between the bottom surface of the support block 1 and the anti-detachment hook 4 via a bearing. The guide wheel 16 is used to cooperate with the guide rail 5 to guide the movement of the transport device.

[0047] like Figure 4 As shown, the anti-slip mechanism also includes an operating rod 10. The operating rod 10 adopts a tubular structure, and its length can be set according to actual use needs. The inner diameter of the operating rod 10 is larger than the outer diameter of the positioning sleeve 2 and the limiting cap 15, so that the operating rod 10 can be sleeved on the outer periphery of the positioning sleeve 2 and the limiting cap 15, and its bottom end can contact and cooperate with the part of the two positioning pins 9 extending to the outside of the positioning sleeve 2.

[0048] In order to better utilize the operating rod 10 to drive the positioning pin to rotate, a slot 17 matching the positioning pin is provided at the bottom end of the operating rod 10, and the bottom end of the operating rod can cooperate with the positioning pin through the slot.

[0049] A straight rod perpendicular to the operating rod 10 is inserted into the top end thereof as a handle 18, which facilitates the staff to press down and rotate the operating rod.

[0050] The working principle based on the above structure is:

[0051] The bottom end of the operating rod 10 is matched with the positioning pin 9 through the slot 17, the positioning pin 9 is inserted into the slot 17, and the operating rod 10 is pressed downward to make the positioning pin 9 move downward along the first slide groove 6 and the third slide groove 8. When the positioning pin 9 moves to the connection position of the second slide groove 7 and the first slide groove 6, the operating rod 10 is rotated. At this time, the positioning pin 9 enters the second slide groove 7 and moves along the second slide groove 7. At the same time, the positioning pin 9 drives the rotating shaft 3 to rotate through the third slide groove 8, and the rotating shaft 3 drives the anti-detachment hook 4 to rotate, thereby making the anti-detachment hook 4 disengage from the matching state with the guide rail 5.

[0052] By adopting the anti-slip mechanism of this embodiment, the staff can open the anti-slip mechanism by operating the operating lever, thus realizing remote operation. There is no need to enter the hot chamber and approach the transport device to open the anti-slip mechanism, which greatly reduces the frequency of the staff entering the hot chamber and avoids or greatly reduces the harm caused by nuclear radiation to the staff when the mechanism is inspected or replaced.

[0053] Example 2

[0054] This embodiment provides a transport device such as Figure 5 As shown, it includes a transport device body 19, which cooperates with the upper flange plate of the I-shaped guide rail 5. The structure of the transport device body and the cooperation method with the guide rail 5 can adopt the existing technology, which will not be described in detail here.

[0055] The front end and / or rear end of the transport device body are both provided with the anti-slip mechanism for easy remote opening as described in Example 1. Preferably, in order to ensure the stability of the movement of the transport device body, the front end and rear end of the transport device body are both provided with the anti-slip mechanism for easy remote opening as described in Example 1. Furthermore, the anti-slip mechanism at the front end and rear end may share an operating rod 10.

[0056] The vertical part of the support block of the anti-slip mechanism is fixedly connected to the transport device body 19 through the side fixing hole 11 and the fixing bolts. The distance between the bottom surface of the support block 1 and the top surface of the guide rail 5 is not greater than 5 mm, preferably 5 mm. The guide wheel 16 cooperates with the side of the upper flange plate of the guide rail 5.

[0057] In this embodiment, as the transport device body moves along the guide rail, the guide wheel 16 plays a guiding role to prevent the transport device from moving in an "S" shape during normal operation. At the same time, the support block 1 can clear obstacles on the guide rail and play a role in clearing the rail. The anti-detachment hook 4 rotates to the bottom of the flange plate on the guide rail, which can prevent the transport device body 19 from becoming a projectile when other external forces act on it, thereby ensuring the stability of transportation. The transport, anti-detachment, track clearing and guiding functions are integrated together, with a compact structure, which effectively reduces the overall dimensions and increases the effective operating space of the transport device.

[0058] When the transport device needs to be inspected and maintained, it is only necessary to use the operating rod 10 to drive the anti-detachment hook 4 to rotate and make it leave the position below the flange plate on the guide rail 5, so that the entire transport device can be lifted off for inspection and maintenance. The staff can open the anti-detachment mechanism through the operating rod, thereby realizing remote operation. There is no need to enter the hot chamber to approach the transport device to open the anti-detachment mechanism, which greatly reduces the frequency of staff entering the hot chamber and avoids or greatly reduces the harm caused by nuclear radiation to staff when the mechanism is inspected or replaced.

[0059] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
