[0024] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0025] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0026] Examples, such as Figure 1 and Figure 4-Figure 6 As shown, an extremely short medium-load three-row chain transfer machine includes a mounting frame 100 , a three-row chain transfer mechanism, a base frame 200 , two sets of lifting components 210 and a driving component 220 .

[0027] The three-row chain transfer mechanism is installed on the mounting frame 100. The three-row chain transfer mechanism includes three groups of chain frames 101, a cross bar 102, three first sprocket wheels 103, three groups of slots 104, three mounting rods 105, three second sprocket wheels 106 and three load chains 107.

[0028] Three groups of chain frames 101 are equidistantly installed on the top surface of the mounting frame 100; the cross bar 102 is rotatably connected to the three chain frames 101; the three first sprockets 103 are respectively located in the three groups of chain frames 101, and the three first sprockets 103 are fixedly sleeved on the cross bar 102; three groups of slots 104 are respectively opened on the three groups of chain frames 101; three mounting rods 105 are respectively slidably connected to the three groups of slots 104; three second sprockets 106 are respectively rotatably sleeved on the three mounting rods 105; three loading chains 107 are respectively located in the three groups of chain frames 101, and the loading chains 107 are sleeved on the first sprocket 103 and the second sprocket 106, and a plurality of support blocks 108 are equidistantly installed on the loading chains 107.

[0029] Specifically, the cargo to be transported is placed on the support block 108 on the cargo chain 107, and then the cross bar 102 is rotated. The rotation of the cross bar 102 drives the three first sprocket wheels 103 to rotate, thereby driving the three cargo chains 107 to move, and then driving the cargo to move.

[0030] like Figure 2As shown, the three-row chain transfer mechanism also includes a mounting seat 110, a first motor 111, a third sprocket 112, a fourth sprocket 113, a first chain 114 and a protective plate 115. The mounting seat 110 is mounted on the bottom of one side of the mounting frame 100; the first motor 111 is mounted on the top surface of the mounting seat 110; the third sprocket 112 is fixedly sleeved on the power output shaft of the first motor 111; the fourth sprocket 113 is fixedly sleeved on the crossbar 102; the first chain 114 is sleeved on the third sprocket 112 and the fourth sprocket 113; the protective plate 115 is mounted on the chain frame 101 closest to the fourth sprocket 113, and the protective plate 115 is used to shield the fourth sprocket 113.

[0031] Specifically, when the first motor 111 is running, it drives the third sprocket 112 to rotate, and then drives the fourth sprocket 113 to rotate through the first chain 114, and then drives the cross bar 102 to rotate.

[0032] like Figure 3 As shown, the three-row chain transfer mechanism includes three groups of adjustment components 120, which are respectively installed on the three groups of chain frames 101. The adjustment components 120 include two fixed blocks 121, two adjustment screws 122 and two nuts 123. The two fixed blocks 121 are respectively installed on both sides of the chain frame 101; one end of the adjustment screw 122 is connected to the mounting rod 105, and the other end of the adjustment screw 122 passes through the fixed block 121 and is slidably connected to the fixed block 121. The adjustment screw 122 can also be rotatably connected to the fixed block 121. The two nuts 123 are respectively threadedly connected to the two adjustment screws 122.

[0033] Specifically, by rotating the nut 123, the position of the nut 123 on the adjusting screw 122 is changed, and then the distance between the nut 123 and the mounting rod 105 is adjusted, and then the distance between the mounting rod 105 and the fixed block 121 is adjusted, and then the distance between the second sprocket 106 and the first sprocket 103 is adjusted, so as to facilitate the adjustment of the tightness of the loading chain 107.

[0034] like Figure 4 and Figure 5 As shown, the base frame 200 is located directly below the mounting frame 100; the four brackets 202 are all mounted on the inner wall of the base frame 200. The two sets of lifting components 210 are used to drive the mounting frame 100 to move upward, and the lifting components 210 include two bearing seats 211, a rotating rod 212, two cams 213, two rotating wheels 214 and a sixth sprocket 215.

[0035] The two bearing seats 211 are both installed on the base frame 200, and the rotating rod 212 passes through the two bearing seats 211 and is rotatably connected to the bearing seats 211; the two cams 213 are respectively fixedly connected to the two ends of the rotating rod 212; the two rotating wheels 214 are respectively installed on the opposite sides of the two cams 213, and the two rotating wheels 214 are respectively located in the two brackets 202; the sixth sprocket 215 is fixedly sleeved on the rotating rod 212.

[0036] Specifically, when the rotating rod 212 rotates, it will drive the two cams 213 to rotate. When the cam 213 rotates, it will drive the rotating wheel 214 to rotate. When the tip of the cam 213 is located above the rotating rod 212, the rotating wheel 214 will lift the bracket 202, thereby driving the mounting frame 100 to move upward; when the tip of the cam 213 is located below the rotating rod 212, the mounting frame 100 will move downward due to the influence of gravity.

[0037] like Figure 4 and Figure 5 As shown, the driving assembly 220 is mounted on the base frame 200, and the driving assembly 220 is used to drive the rotating rods 212 in the two lifting assemblies 210 to rotate. The driving assembly 220 includes a second motor 221, two fifth sprockets 222, two second chains 223 and two second chains 223. The second motor 221 is mounted on the base frame 200; the two fifth sprockets 222 are fixedly sleeved on the power output shaft of the second motor 221; the second chain 223 is sleeved on the fifth sprocket 222 and the sixth sprocket 215.

[0038] Specifically, when the second motor 221 rotates, it drives the two fifth sprockets 222 to rotate, and then drives the two second chains 223 to rotate, and then drives the two sixth sprockets 215 to rotate, and then drives the two rotating rods 212 to rotate simultaneously.

[0039] like Figure 1 As shown, grooves 109 are provided at the bottom of the three groups of chain frames 101, and the second motor 221 is located directly below the three grooves 109. Under normal circumstances, the second motor 221 can be in the groove 109, which reduces the overall height of the device and further reduces the occupied space of the device.

[0040] like Figure 1 , Figure 4 and Figure 5 As shown, the extremely short medium-load three-row chain transfer machine further includes two guide seats 130 and two guide rods 201 .

[0041] The two guide seats 130 are respectively installed on both sides of the mounting frame 100, and a through hole is opened at the center position of the guide seat 130; the two guide rods 201 are respectively installed on both sides of the base frame 200, and the two guide rods 201 respectively penetrate the through holes on the two guide seats 130 and are slidably connected with the guide seats 130.

[0042] Specifically, by providing the guide rod 201 and the guide seat 130 , it is possible to prevent the mounting frame 100 from being offset during lifting, thereby facilitating improving the stability of the mounting frame 100 during lifting.

[0043] Working principle: When in use, the goods to be transported are placed on the supporting blocks 108 of the three loading chains 107 .

[0044] Then, by starting the first motor 111, the power output shaft of the first motor 111 drives the third sprocket 112 to rotate, and then drives the fourth sprocket 113 to rotate through the first chain 114, and then drives the cross bar 102 to rotate. When the cross bar 102 rotates, it will drive the three first sprockets 103 to rotate, and then drive the three cargo chains 107 to move, and then drive the support block 108 and the goods on the support block 108 to move.

[0045] Then, by starting the second motor 221, the power output shaft of the second motor 221 drives the two fifth sprockets 222 to rotate, and then drives the two sixth sprockets 215 to rotate through the two second chains 223, and then drives the two rotating rods 212 to rotate, which will drive the four cams 213 to rotate, and then drive the four rotating wheels 214 to rotate. When the tip of the cam 213 is located above the rotating rod 212, the four rotating wheels 214 will lift the four brackets 202, and then drive the mounting frame 100 to move upward, so that the three-row chain transfer mechanism and the cargo move upward.

[0046] Before use, the position of the nut 123 on the adjusting screw 122 is changed by rotating the nut 123, thereby adjusting the distance between the nut 123 and the mounting rod 105, thereby adjusting the distance between the mounting rod 105 and the fixing block 121, and thereby adjusting the distance between the second sprocket 106 and the first sprocket 103, thereby facilitating the adjustment of the tightness of the loading chain 107.

[0047] By providing grooves 109 at the bottoms of the three sets of chain frames 101 , the second motor 221 can be located in the grooves 109 under normal conditions, thereby reducing the overall height of the device and further reducing the space occupied by the device.
