However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Example 1
[0028] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a cargo transfer machine, including,
[0029] The main structure 100 includes a bearing base 101, a support foot 102 fixedly installed at the bottom of the bearing base 101, a lifting assembly 103 adapted to be installed on the outer surface of the bearing base 101, a lifting bracket 104 set at the top of the bearing base 101, and a transport assembly 105 adapted to be installed on the top of the lifting bracket 104 for transporting the load.
[0030] And a tensioning mechanism 200 for adjusting the tension of the drive chain of the lifting assembly 103, the lifting assembly 103 being connected to the lifting bracket 104 for driving the transport assembly 105 to move in the vertical direction.
[0031] It should be noted that the supporting base 101 and the lifting bracket 104 are plugged and plugged together, and the bottom of the lifting bracket 104 is provided with several roller followers that cooperate with the lifting component 103 to carry out the lifting operation. The transport component 105 includes a conveying roller, a rotary motor, a pulley, a belt, etc. The rotary motor drives the belt through the pulley, and the belt drives the pulley fixed coaxially with the conveying roller to rotate, thereby driving the conveying roller to rotate and realize the transport of goods.
[0032] Specifically, the tensioning mechanism 200 includes a lateral adjustment component 201 adapted to be installed at the bottom of the support base 101, a vertical adjustment component 202 disposed at the top of the lateral adjustment component 201, a buffer component 203 disposed at the top of the vertical adjustment component 202, and a tensioning wheel 204 disposed on the outer surface of the buffer component 203.
[0033] Furthermore, the lateral adjustment assembly 201 includes a movable rod 201a fixedly installed at the bottom of the support base 101, a limiting track 201b formed on the outer surface of the movable rod 201a, and a sliding sleeve 201c slidably sleeved on the outer surface of the movable rod 201a.
[0034] Furthermore, the lateral adjustment assembly 201 also includes two locking blocks 201d disposed on the inner wall of the sliding sleeve 201c, a locking spring 201e fixedly connected to the inner side of the locking block 201d, and a baffle 201f fixedly installed on the inner wall of the sliding sleeve 201c, with the baffle 201f fixedly connected to the end faces of the two locking springs 201e on both sides respectively.
[0035] It should be noted that the cross-section of the movable rod 201a is polygonal to prevent radial displacement when the sliding sleeve 201c slides. The inner wall of the sliding sleeve 201c is provided with a guide groove for the sliding of the locking block 201d, and the baffle 201f is used to limit the lateral movement of the locking block 201d.
[0036] Preferably, the vertical adjustment assembly 202 includes a lifting seat 202a fixedly mounted on the top of the sliding sleeve 201c, an internally threaded block 202b that slides in contact with the inner wall of the lifting seat 202a, and a lifting block 202c that slides in contact with the inclined surface of the internally threaded block 202b.
[0037] Specifically, the vertical adjustment assembly 202 also includes a limiting rod 202d that is inserted into and slides in contact with the lifting seat 202a on both sides, and a lifting platform 202e that is fixedly connected to the top of the limiting rod 202d. An inclined guide surface is provided on one side of the outer surface of the internal thread block 202b, and a wedge-shaped groove that cooperates with the inclined guide surface is provided at the bottom of the lifting block 202c.
[0038] Furthermore, the vertical adjustment assembly 202 also includes a lead screw 202f rotatably connected to the inner surface of the lifting seat 202a, a bushing 202g fixedly sleeved on the outer surface of the lead screw 202f, and an adjustment ring 202h fixedly connected to the end face of the lead screw 202f. The outer surface of the bushing 202g is rotatably connected to the inner surface of the lifting seat 202a. The lead screw 202f is threadedly connected to the internal thread block 202b. The rotation of the lead screw 202f drives the lifting block 202c to move along the inclined guide surface through the internal thread block 202b, thereby causing the lifting platform 202e to rise and fall vertically along the limit rod 202d.
[0039] Furthermore, the buffer assembly 203 includes a buffer sleeve 203a fixedly installed on the top of the lifting seat 202a, two buffer springs 203b vertically fixed to the inner wall of the buffer sleeve 203a, and a buffer block 203c fixedly connected to the top of the buffer springs 203b, with the outer surface of the buffer block 203c slidingly contacting the inner wall of the buffer sleeve 203a.
[0040] Furthermore, the tensioner 204 is rotatably connected to the buffer block 203c via a rotating shaft, and the two ends of the rotating shaft are equipped with bearing sleeves for use with it.
[0041] Specifically, the buffer block 203c has guide protrusions on both sides to prevent radial displacement, and the inner wall of the buffer sleeve 203a has guide grooves that slide with the guide protrusions.
[0042] During use, simultaneously press the locking blocks 201d on both sides of the sliding sleeve 201c. At this time, the locking blocks 201d unlock from the limiting track 201b, and the locking spring 201e is compressed. Maintain the pressed state of the locking blocks 201d and move the lateral sliding sleeve 201c to the appropriate position. Then, release the pressure on the locking blocks 201d, and the locking spring 201e pushes the locking blocks 201d back to the locked position, completing the horizontal position adjustment of the tension wheel 204. Next, by rotating the adjusting ring 202h, the lead screw 202f is rotated. The internal threaded block 202b, which is threaded to the lead screw 202f, slides back and forth along the lead screw 202f in the groove opened on the surface of the lifting seat 202a. The lifting block 202c moves along the inclined guide surface. Due to the action of the limiting rod 202d, the lifting platform 202e rises and falls with the rotation of the adjusting ring 202h, thereby adjusting the vertical height of the tension wheel 204. When the tension wheel 204 is adjusted to a suitable position, the tension wheel 204 meshes with the lifting chain and supports it at a certain angle. At this time, the lifting assembly 103 is started. As the lifting assembly 103 runs, the tension of the chain changes continuously, causing the force on the tension wheel 204 to change. The buffer block 203c, which is rotatably connected to it, slides up and down repeatedly along the buffer sleeve 203a. The buffer spring 203b is continuously compressed and released, completing the elastic buffering.
[0043] In summary, the main structure 100, with the rigid support of the bearing base 101 and the support feet 102, ensures the overall stability of the transfer machine structure. The lateral adjustment component 201 and the vertical adjustment component 202 work together to quickly and flexibly adjust the tension wheel 204 without tools, improving adjustment efficiency. The buffer component 203 dynamically adjusts to maintain appropriate chain tension, thereby better meshing with the sprocket, reducing chain swaying and jumping, and thus reducing wear on the lifting component 103. Through the cooperation of the lifting component 103 and the tensioning mechanism 200, the precise lifting of the transport component 105 is achieved.
