[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 5 As shown, an embodiment of the present application provides a circulating elevator, which includes a frame 101, on which an inner guide rail 113 and an outer guide rail 114 are provided, and a column 110 is provided in the frame 101, and a support platform 108 is provided at the top of the column 110, and an upper support shaft 109 is provided on the support platform 108, and an upper sprocket 102 is provided on the upper support shaft 109, and a lower support seat 111 is provided at the lower end of the column 110, and a lower support shaft 112 is provided on the lower support seat 111, and a lower sprocket 103 is provided on the lower support shaft 112, and also includes a trolley 104 and a chain 115, and the two ends of the chain 115 are respectively connected to the trolley 104, and the chain 115 is also connected to the upper sprocket 102 and the lower sprocket 103, and a frame body is provided on the trolley 104, and one end of the frame body is connected to the cargo platform 105. As shown Figures 3 to 5 As shown, the trolley 104 includes a housing 1041, a floating side guide wheel 1043 assembly is disposed in the housing 1041, and a tensioning assembly is also disposed in the housing 1041. The tensioning assembly is in contact with the side guide wheel 1043 assembly, and the tensioning assembly is used to apply an outward thrust to the side guide wheel 1043 assembly, so that the side guide wheel 1043 assembly abuts against the outer guide rail 114. Figure 5 and Figure 6 As shown, mounting plates 1052 are respectively provided at both ends of the shell 1041 , and each mounting plate 1052 is provided with a guide block 1053 extending along the length direction of the chain 115 , and both sides of the chain 115 are limited by the guide block 1053 and the inner guide rail 113 respectively.

[0032] In one embodiment, the upper support shaft 109 is connected to the reducer 107 , the reducer 107 is connected to the upper support seat, and a driving motor 106 is arranged above the reducer 107 .

[0033] Specifically, the driving motor 106 drives the reducer 107 to operate, the reducer 107 drives the upper support shaft 109 to rotate, the upper support shaft 109 drives the upper sprocket 102 to rotate, the upper sprocket 102 drives the chain 115 to move, and the chain 115 drives the trolley 104 to circulate along the corresponding track. Since the driving motor 106 is arranged above the reducer 107, the overall width of the circulating elevator can be reduced.

[0034] In one embodiment, the guide rail block 1053 includes a base portion and a protrusion extending along the length direction of the base portion. The protrusion is used to be inserted into the chain 115.

[0035] In one embodiment, a long hole 1045 is provided on the shell 1041, and the side guide wheel 1043 assembly includes a side guide wheel support shaft 1042 and a side guide wheel 1043, and the two ends of the side guide wheel support shaft 1042 are respectively located in the corresponding long holes 1045, and the side guide wheel 1043 is two bearings installed on the side guide wheel support shaft 1042, and a spacer sleeve 1044 is also provided between the bearing and the shell 1041 and is sleeved on the support shaft.

[0036] In one embodiment, the tensioning assembly includes a thrust frame 1046, a spring 1048 and a spring seat 1047. The number of spring seats 1047 is two, and the two spring seats 1047 are respectively arranged corresponding to the two ends of the thrust frame 1046. The spring seat 1047 is connected to the shell 1041. A guide column 1049 is arranged on the spring seat 1047. The two ends of the thrust frame 1046 are sleeved on the corresponding guide columns 1049. A spring 1048 sleeved on the guide columns 1049 is arranged between the spring seat 1047 and the thrust frame 1046, and the thrust frame 1046 is abutted against the spacer sleeve 1044.

[0037] Specifically, the spring 1048 applies a thrust to the thrust frame 1046, which causes the thrust frame 1046 to apply a thrust to the spacer 1044. Since the spacer 1044 is mounted on the side guide wheel support shaft 1042, the side guide wheel support shaft 1042 drives the side guide wheel 1043 thereon to closely abut against the outer guide rail 114 under the action of the thrust frame 1046. Even if the outer guide rail 114 is uneven, the side guide wheel 1043 can always maintain good contact with the outer guide rail 114. This is conducive to ensuring the smooth operation of the trolley 104.

[0038] In one embodiment, the spring seat 1047 includes a horizontal plate and two side plates located at both ends of the horizontal plate and arranged perpendicular to the horizontal plate. The shell 1041 is provided with a long stepped hole 1054, and a first type of bolt 1050 is provided in the long stepped hole 1054. The first type of bolt 1050 is connected to the side plate. The shell 1041 is also provided with a second type of bolt 1051, and the second type of bolt 1051 is connected to the horizontal plate. The guide column 1049 is provided on the horizontal plate.

[0039] Specifically, two first-type bolts 1050 can be connected to a side plate, and two second-type bolts 1051 can be connected to the horizontal plate. By adjusting the first-type bolts 1050 and the second-type bolts 1051, the position of the spring seat 1047 relative to the shell 1041 can be adjusted, and then the thrust of the spring 1048 can be adjusted.

[0040] In one embodiment, the rack 101 includes a vertical frame 1011 and a horizontal frame 1012, the bottom end of the vertical frame 1011 is arranged on the horizontal frame 1012, the first part 1012a of the horizontal frame 1012 is located on the front side of the vertical frame 1011, and the second part 1012b of the horizontal frame 1012 is located on the rear side of the vertical frame 1011, and the length of the first part 1012a is longer than the length of the second part 1012b.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
