DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the technical scheme in the utility model embodiment will be described clearly and completely in the following with the drawings in the utility model embodiment, obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment.

[0023] In the description of the embodiments of the application, it should be noted that the directions or position relationships indicated by the terms "inner", "outer", "upper", etc. are based on the directions or position relationships shown in the drawings, or the directions or position relationships commonly placed when the product of the application is used, and are only for the convenience of describing the application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular direction, be constructed and operated in a particular direction, and therefore cannot be understood as limiting the application.

[0024] A transport trolley of a cumulative conveying line, comprising a trolley body 1, a chain wheel 2 and a supporting mechanism 5, the trolley body 1 is connected with the chain wheel 2 through the supporting mechanism 5, and the chain wheel 2 is located at the inner side of the trolley body 1; a pressing stabilizing mechanism 3 and a load adjusting mechanism 4, the pressing stabilizing mechanism 3 comprises a floating block 31 and a first pressing shaft 32, the floating block 31 drives the first pressing shaft 32 to move on the Y axis, and the first pressing shaft 32 is pressed against the surface of the chain wheel 2.

[0025] As shown in Figure 3 , the pressing stabilizing mechanism 3 further comprises a second pressing shaft 33, a gap is left between the second pressing shaft 33 and the first pressing shaft 32, and the teeth on the chain wheel 2 are inserted into the gap and abut against the surfaces of the first pressing shaft 32 and the second pressing shaft 33.

[0026] As shown in Figure 3 , the floating block 31 is connected with a telescopic piece 34, and the telescopic piece 34 comprises a butterfly spring, a hydraulic telescopic rod, an electric telescopic rod or a pneumatic telescopic rod.

[0027] It needs to be explained that the transport trolley uses the telescopic piece 34 to make the floating block 31 up and down floating or telescoping. When the sprocket 2 passes through the driving end and the driven end of the accumulation type conveying line, the sprocket 2 is engaged with the traction chain while generating a polygon effect, the chain will float up and down, the sprocket 2 cannot be fully engaged with the chain, the floating block 31 will be pushed down by the telescopic piece 34, the first pressure shaft 32 and the second pressure shaft 33 on the floating block 31 will clamp the sprocket 2, because the telescopic piece 34 is compressed or self-extended, retracted, the downward pressure will press the sprocket 2 on the chain, and the traction chain moves together, so that the trolley can realize stable conveying on the driving end and the driven end of the accumulation type conveying line.

[0028] The polygon effect refers to that when the chain is just engaged with the sprocket 2, the sprocket 2 rotates through a tooth, the horizontal direction chain speed changes from small to large and then from large to small once, and at the same time, the chain vertically moves up and down once. The chain shakes up and down, and the contact part is a polygon part. The unevenness of the chain transmission caused by the existence of the polygon is called the polygon effect of the chain transmission.

[0029] As shown in Figure 3 , the inner wall of the trolley body 1 is provided with a mounting block 35, the mounting block 35 is connected with the telescopic piece 34, and the telescopic piece 34 is located between the mounting block 35 and the sprocket 2.

[0030] As shown in Figure 1 , the load adjusting mechanism 4 includes a compression spring 41 and a locking nut 42. The locking nut 42 abuts against one end of the compression spring 41, and the other end of the compression spring 41 abuts against the surface of the sprocket 2.

[0031] As shown in Figure 1 , the load adjusting mechanism 4 further includes a shaft rod 43. The compression spring 41 and the sprocket 2 are sleeved on the shaft rod 43, and the locking nut 42 is threadedly connected with the shaft rod 43. When the locking nut 42 is tightened, the compression spring 41 is gradually compressed to increase the accumulation friction force. The compression spring 41 abuts against the sprocket 2, so that the sprocket 2 cannot rotate randomly under the accumulation friction force obtained by the compression spring 41.

[0032] As shown in Figure 2 , the supporting mechanism 5 includes a transverse block 51, the transverse block 51 is fixedly connected with a connecting rod 52, the surface of the connecting rod 52 penetrates a through hole, and the shaft rod 43 penetrates through the through hole and is fixedly installed on the connecting rod 52.

[0033] As shown in Figure 2 , the transverse block 51 is connected with a buffer spring 53, the transverse block 51 is provided with a vertical block 54, and one end of the buffer spring 53 away from the transverse block 51 is connected to the vertical block 54. The buffer spring 53 floats up and down or telescopes with the telescopic piece 34, and the buffer spring 53 provides a buffering space for the supporting mechanism 5.

[0034] As Figure 3 shown, the vertical block 54 is fixedly connected with the mounting plate 55 away from one side of the horizontal block 51, and the mounting plate 55 is mounted on the vehicle body 1.

[0035] As Figure 2 shown, at least two side wheels 6 are mounted on the inner side of the vehicle body 1, and the side wheels 6 are mounted on the eccentric side of the vehicle body 1, not the middle position of the weight and volume of the vehicle body 1. During the transportation process of the transport trolley, the support mechanism 5 is located at the front end position in the transportation direction, not at the rear end position. When the support mechanism 5 is located at the rear end position, the support mechanism 5 will hit the chain.

[0036] Embodiment: The transport trolley uses the compression spring 41 to adjust the accumulated and deposited friction force. The sprocket 2 and the compression spring 41 are used as the load adjusting mechanism 4 composed of the shaft rod 43 and the locking nut 42. The load adjusting mechanism 4 and the vehicle body 1 are connected together by the support mechanism 5. When the locking nut 42 is tightened, the compression spring 41 is gradually compressed to increase the accumulated and deposited friction force. The compression spring 41 abuts against the sprocket 2 to prevent the sprocket 2 from rotating randomly under the accumulated and deposited friction force obtained by the compression spring 41. Therefore, when the load needs to be increased, the locking nut 42 is tightened towards the sprocket 2. When the load needs to be decreased, the locking nut 42 is loosened away from the sprocket 2. In addition, the telescopic piece 34 is used to make the floating block 31 float up and down. When the sprocket 2 passes through the driving end and the driven end of the accumulated and deposited conveying line, the sprocket 2 and the traction chain are engaged to generate a polygon effect. The chain floats up and down, and the sprocket 2 cannot be completely engaged with the chain. The floating block 31 is caused to float up and down by the telescopic piece 34. The first pressing shaft 32 and the second pressing shaft 33 on the floating block 31 clamp the sprocket 2. Because the telescopic piece 34 is compressed or can give a compression force to the floating block 31 autonomously, the sprocket 2 is stably pressed on the chain to move together with the traction chain, so that the transport trolley can be stably transported on the driving end and the driven end of the accumulated and deposited conveying line.

[0037] The basic principles, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and various changes and improvements can be made without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application. The scope of protection required by the present application is defined by the appended claims and their equivalents.
