Description

Technical Field

[0001] The utility model relates to the technical field of lifting frames, in particular to a lifting frame for loading road goods. Background Art

[0002] A road cargo loading lift is a device used to transport cargo or people vertically. Its main function is to help lift cargo from the ground to a vehicle or unload it from a vehicle. This type of lift usually has a sturdy structure and stable operating performance to meet the specific needs of road cargo loading.

[0003] The existing Chinese patent "A loading rack for cargo transportation" with the announcement number CN218288863U proposes an effective solution to the shortcomings of the fixed racks in the current market that are inconvenient to load and transfer. By converting the original fixed racks into movable racks that can be raised and lowered, they can be fixed as display racks when not in use; when in use, the transfer device of the cargo can be controlled by lifting and lowering, achieving the technical effect of one machine with multiple uses. However, in actual use, since the slider and the slide are connected by sliding, the rack is in an unstable state when it rises to the highest point, which poses a safety hazard and has certain deficiencies in use. For this reason, we propose a lifting rack for road cargo loading. Summary of the invention

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] Reference Figure 1-3A lifting frame for loading road goods, comprising a frame 1, a universal wheel 2 is installed at the bottom of the frame 1, a foot brake is installed on the universal wheel 2, a push frame 3, a support mechanism 4, a telescopic rod 5 and a lifting mechanism 7 are installed on the top of the frame 1, the support mechanism 4 comprises a fixed seat 41 fixed on the frame 1 and a support frame 46 fixed on the top of the telescopic rod 5, a first motor 42 is installed inside the fixed seat 41, first threaded columns 43 are installed on the output shafts on both sides of the first motor 42, a first slider 44 is connected to the first threaded column 43 by threading, a connecting rod 45 is rotatably connected to the top of the first slider 44, fixed blocks 47 are installed at both ends of the bottom of the support frame 46, a guide shaft 48 is installed between the fixed blocks 47, a second slider 49 is installed at both ends of the guide shaft 48, the second slider 49 is rotatably connected to the connecting rod 45, the first motor 42 is a double-axis motor, the threads of the two first threaded columns 43 are in opposite directions, the first slider 44 is slidably connected to the fixed seat 41, and the two connecting rods 45 are rotatably connected Next, a loading platform 6 is installed on the side of the lifting mechanism 7. The lifting mechanism 7 includes a fixing frame 71 fixed on the frame 1. A second threaded column 72 is fixed inside the fixing frame 71. A threaded sleeve 73 is threadedly connected to the second threaded column 72. A worm gear 74 is fixedly sleeved on the threaded sleeve 73. A housing 75 is rotatably connected to the threaded sleeve 73. A second motor 76 is installed on the back of the housing 75. The output shaft of the second motor 76 is inserted into the interior of the housing 75 and is connected to a worm 77. The worm gear 74 and the worm 77 are meshing transmissions. The housing 75 and the fixing frame 71 are slidably connected. The loading platform 6 is installed on the side of the housing 75. The supporting mechanism 4 is fixed to the telescopic rod 5. The supporting mechanism 4 is used to support the loading platform 6. By setting a lifting mechanism and using the lifting mechanism to drive the loading platform to load goods, the time for handling goods can be greatly saved. At the same time, during the lifting process of the goods, the supporting mechanism cooperates with the telescopic rod so that the supporting mechanism supports the loading platform from the bottom, which can effectively improve the stability of the loading platform.

[0017] The device is moved by pushing the push frame 3 in cooperation with the universal wheel 2 to move the device to the work site, and the universal wheel 2 is locked by the foot brake, and then the device is connected to the power supply. During use, the goods are transported to the loading platform 6, and the second motor 76 is started. The output shaft of the second motor 76 drives the worm 77 to rotate, and the worm 77 drives the threaded sleeve 73 to rotate through the meshing transmission with the worm wheel 74. The threaded sleeve 73 drives the housing 75 to slide in the fixed frame 71 through the thread transmission with the second threaded column 72, and the housing 75 drives the loading platform 6, and the loading platform 6 is used to lift the goods, and then The first motor 42 is started, and the output shaft of the first motor 42 drives the first threaded column 43 to rotate. The first threaded column 43 drives the first slider 44 to slide in the fixed seat 41 through the thread transmission with the first slider 44. Since the rotation directions of the threads of the two first threaded columns 43 are opposite, the two first sliders 44 approach each other. The first slider 44 drives the second slider 49 to slide on the guide shaft 48 through the connecting rod 45. At this time, the second slider 49 is away from the first slider 44, and then the support frame 46 is away from the frame 1, so that the support frame 46 supports the loading platform 6 from the bottom, thereby improving its stability in use.

[0018] To sum up, compared with the prior art, the utility model can greatly save the time of cargo transportation by setting up a lifting mechanism, and utilizing the lifting mechanism to drive the loading platform to load cargo. At the same time, during the cargo lifting process, the supporting mechanism cooperates with the telescopic rod to support the loading platform from the bottom, which can effectively improve the stability of the loading platform.
