[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides Figure 1-4 The shown ground rail type trolley conveyor chain comprises a fixed block 1 and a moving wheel set a2 installed inside the fixed block 1;

[0026] The left and right sides of the fixed block 1 are respectively provided with moving wheel sets b5;

[0027] The upper outer wall of the fixed block 1 is fixedly connected with a connecting rod 7;

[0028] The front circular outer wall of the connecting rod 7 is equidistantly provided with a plurality of fixing holes 8. The inner sides of the upper and lower inner walls of the two moving wheel sets b5 are both provided with connecting plates 4. When the chain drives the trolley to move, the chain is first installed inside the ground rail, and the connecting rod 7 and the trolley are connected and fixed. Then, the chain is driven by an external driving motor to move. When the chain moves, the moving wheel set a2 is in contact with the inner walls of the upper and lower ends of the ground rail to limit the position of the connecting rod 7. The two moving wheel sets b5 are in contact with the inner walls of the left and right ends of the ground rail to drive the moving wheel set a2 to move.

[0029] A groove 10 is provided at the center of the circular outer wall of the connecting rod 7 to divide the connecting rod 7 into two parts, an upper part and an lower part. A positioning column 11 is fixedly connected to the inside of the lower connecting rod 7 to limit the moving direction of the upper connecting rod 7. When the connecting rod 7 and the trolley are connected, the connecting rod 7 is divided into upper and lower sides by the groove 10. The connecting rod 7 with the fixing hole 8 on the upper side can be pulled to move to adapt to the installation position of the trolley, and when the upper connecting rod 7 is pulled, it will move under the restriction of the positioning column 11.

[0030] like Figure 2 and Figure 3As shown, the upper end outer wall of the lower connecting rod 7 and the left and right sides are respectively fixedly connected with a fixing plate 13 that penetrates upward into the interior of the upper connecting rod 7, and a movable plate 14 is provided on the opposite side of the two fixing plates 13. One end of the two movable plates 14 is fixedly connected with a fixing screw 15 that penetrates the fixing plate 13, and one end of the two fixing screws 15 is threadedly connected with a nut b18, and one side of the two nuts b18 is provided with a nut a16, and a connecting block 17 is fixedly connected between the two nuts a16 and the nuts b18 to limit the position between the nuts a16 and the nuts b18, and a downward-opening limiting groove 9 is provided inside the outer wall of the lower end of the upper connecting rod 7, and a scale 12 is embedded in the front end outer wall of the positioning column 11.

[0031] When pulling the upper connecting rod 7 to move, first insert the nut a16 with the help of an external screwdriver and rotate it to make the nut b18 move away from the fixed plate 13, and then pull the upper connecting rod 7 upward to move. During the movement, the distance can be controlled with the help of the ruler 12. When it moves to the appropriate distance, insert the nut a16 with the help of an external screwdriver again and rotate it to make the nut b18 fit the fixed plate 13, so that the movable plate 14 and the fixed plate 13 can be fixed, limiting the position of the upper connecting rod 7 after pulling.

[0032] like Figure 4 As shown, a slot 22 opening upward is provided inside the outer wall of the upper end of the fixed block 1, and a block 19 penetrating downward into the slot 22 is fixedly connected at the center of the lower outer wall of the lower connecting rod 7. A threaded hole 21 opening downward is provided inside the outer wall of the lower end of the block 19, and a threaded column 20 threadedly engaged with the threaded hole 21 is fixedly connected to the inner wall of the lower end of the slot 22 to limit the position of the connecting rod 7.

[0033] When the entire connecting rod 7 is damaged, the connecting rod 7 can be rotated counterclockwise so that the block 19 rotates in the slot 22, separating the threaded hole 21 and the threaded column 20. The damaged connecting rod 7 can be removed, and the block 19 at the lower end of the replaced connecting rod 7 can be reinserted into the slot 22 and rotated so that the threaded hole 21 and the threaded column 20 are screwed together, thereby completing the fixation of the connecting rod 7.

[0034] like Figure 2 As shown, the centers of the two fixing plates 13 are each provided with a through opening extending leftward and rightward to limit the movable direction of the fixing screw 15 , and the right side of the nut a16 is closed and provided with a cross slot.

[0035] A through hole is provided inside the fixing plate 13 so that the fixing screw 15 in a fixed state can only move up and down in the through hole. A cross slot is provided on the right side of the nut a16 so that a flat-head or cross screwdriver can be inserted to drive the nut a16 to rotate.

[0036] like Figure 1 As shown, positioning pins b6 are inserted between the multiple connecting plates 4 and the fixed block 1, and positioning pins a3 viewed backward are provided on the front outer wall of the fixed block 1 and close to the left and right sides respectively to limit the position of the positioning pins b6.

[0037] When connecting the moving wheel group a2 and the moving wheel group b5, first place the connecting plate 4 in the moving wheel group b5 on the fixed block 1, then insert the positioning pin b6 into the holes opened inside the connecting plate 4 and the fixed block 1, and then insert the positioning pin a3 from the front side of the fixed block 1 and pass through the positioning pin b6 to complete the fixation between the moving wheel group a2 and the moving wheel group b5.

[0038] The implementation principle of this embodiment is as follows: when the chain drives the trolley to move, the chain is first installed inside the ground rail, and the connecting rod 7 and the trolley are connected and fixed, and then the chain is driven to move by an external driving motor. When the chain moves, the moving wheel group a2 sticks to the inner walls of the upper and lower ends of the ground rail to limit the position of the connecting rod 7, and the two moving wheel groups b5 stick to the inner walls of the left and right ends of the ground rail to drive the moving wheel group a2 to move. When connecting the connecting rod 7 and the trolley, the connecting rod 7 is divided into upper and lower sides by the groove 10. It can be moved by pulling the connecting rod 7 with the fixing hole 8 on the upper side to adapt to the installation position of the trolley, and when the upper connecting rod 7 is pulled, it will move under the restriction of the positioning column 11.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
