Referring to fig. 1 and 4, the present invention discloses a safety lifting mechanism, including a base frame 100, a support bracket 200 and a support member 300, wherein the support bracket 200 is used for supporting goods, a driving mechanism 400 drives the support bracket 200 to lift relative to the base frame 100, so as to transport or transfer goods at different heights, the support member 300 is disposed on the base frame 100, the support member 300 is used for supporting the support bracket 200, and preventing the support bracket 200 from falling without limitation, the support member 300 can also lift relative to the base frame 100, it should be understood that the support member 300 of the lifting mechanism can keep a synchronous lifting state with the support bracket 200, and the lifting safety of the support bracket 200 is ensured.

According to the safety lifting mechanism, the supporting piece 300 used for supporting the supporting bracket 200 is arranged, and in the lifting motion process of the supporting bracket 200 driven by the driving mechanism 400, the supporting piece 300 and the supporting bracket 200 can be lifted synchronously, so that continuous supporting guarantee is provided for the supporting bracket 200 and goods on the supporting bracket 200. Because of the existence of the supporting member 300, when the driving mechanism 400 fails or structural members in the driving mechanism 400 fail, the supporting member 300 can still support the support bracket 200, thereby effectively avoiding the bad conditions of linear falling and the like of the support bracket 200, ensuring the structural stability of the support bracket 200 and the goods on the support bracket 200, and preventing safety accidents. The lifting mechanism well eliminates the potential safety hazard of the support bracket 200 caused by the failure of the driving mechanism 400 through the arrangement of the support member 300, and has strong safety protection performance.

Referring to fig. 1, 2 and 4, in the present embodiment, the base frame 100 and the support bracket 200 are each in a frame shape, the two support members 300 are respectively located at the left and right ends of the bottom of the support bracket 200, that is, the support bracket 200 abuts against the two support members 300, so as to ensure the stability of the lifting of the support bracket 200, and the two power members 500 are correspondingly arranged and respectively installed on the left and right sides of the base frame 100. It should be understood that the support bracket 200 is driven by the driving mechanism 400 to move up and down relative to the base frame 100, and the support member 300 is driven by the power member 500 to move up and down relative to the base frame 100, and the entire lifting mechanism is operated such that the support bracket 200 is always abutted against the support member 300, and the support bracket 200 and the support member 300 are driven by the driving mechanism 400 and the power member 500 to perform synchronous lifting and lowering movements, respectively.

Obviously, in the whole lifting mechanism, when the driving mechanism 400 is out of order, for example, when structural members in the driving mechanism 400 are damaged, the existence of the supporting member 300 can well avoid the falling of the supporting bracket 200, so as to provide safety protection for the supporting bracket 200, the goods on the supporting bracket 200 and the whole lifting mechanism, and meanwhile, the power member 500 can also continue to drive the supporting member 300 to perform lifting movement, so that the supporting bracket 200 can continue to perform linear lifting movement along with the supporting member 300 due to the fact that the supporting bracket 200 is stably abutted on the supporting member 300 all the time, and the transportation and transfer of the goods can be continued.

In some embodiments of the present invention, referring again to fig. 1, 4 and 5, the power member 500 is a rodless cylinder, and the support member 300 is fixedly connected to the slider 510 of the rodless cylinder. It is easy to understand that the slider 510 of the rodless cylinder drives the support 300 to perform a reciprocating linear motion. In this embodiment, the rodless cylinder has two, respectively vertically install on the wall of the left and right sides of bed frame 100, correspond the cooperation with two supporting pieces 300 respectively, supporting piece 300 is the steel sheet, strengthen the bearing capacity of supporting piece 300, the steel sheet accessible bolt or screw etc. are connected on slider 510, make things convenient for the installation of rodless cylinder, obviously, when guaranteeing that supporting piece 300 can go up and down relative to bed frame 100, installation space has been saved to a great extent to the design of rodless cylinder for whole elevating system has more beautifully and wholeness.

In some embodiments of the present invention, referring to fig. 1 and 3 again, in order to ensure the stability of the goods on the supporting bracket 200 during the lifting process, at least one guide rail 110 is provided on the base frame 100, the supporting bracket 200 is slidably connected to the guide rail 110, and the driving mechanism 400 drives the supporting bracket 200 to slide up and down along the guide rail 110. In addition, the support bracket 200 is correspondingly provided with a connecting frame 210 which is matched with the guide rail 110, and the support bracket 200 is connected with the guide rail 110 in a sliding way through the connecting frame 210. In this embodiment, the two sides of the base frame 100 are both vertically provided with the guide rails 110, and the two connecting frames 210 are correspondingly arranged on the left side and the right side of the supporting bracket 200 respectively and are correspondingly connected with the guide rails 110 in a sliding manner, so that the supporting bracket 200 can stably slide up and down on the guide rails 110, and the occurrence of adverse conditions such as instability and shaking of the supporting bracket 200 is avoided. In addition, in this embodiment, the connecting frame 210 is perpendicular to the supporting bracket 200, and the connecting frame 210 is triangular, so as to enhance the structural stability of the supporting bracket 200, further ensure that the supporting bracket 200 can smoothly complete the lifting operation, and realize the function of safely conveying goods.

In some embodiments of the present invention, referring to fig. 1 again, the driving mechanism 400 includes a cylinder 410, a belt 420, a linkage frame 430 and a movable pulley 440 cooperating with the belt 420, the cylinder 410 is vertically installed on the base frame 100 and the output end thereof is connected with the linkage frame 430, the movable pulley 440 is disposed on the linkage frame 430, one end of the belt 420 is fixedly connected with the base frame 100, and the other end of the belt 420 is connected with the support bracket 200.

It should be understood that, in this embodiment, the output end of the air cylinder 410 is a piston rod of the air cylinder 410, the air cylinder 410 is vertically installed at the middle position of the base frame 100, the linking frame 430 is located above the air cylinder 410 and connected to the piston rod of the air cylinder 410, fixing members are fixedly installed on the bottom end of the base frame 100 and the support bracket 200, one end of the belt 420 is fixed on the fixing member on the base frame 100, and the other end of the belt 420 is fixed on the fixing member on the support bracket 200 after being wound around a part of the periphery of the movable pulley 440. It should be understood that the driving mechanism 400 is equivalent to a movable pulley mechanism, and compared with the conventional way of using a single linear cylinder to drive the support bracket 200 to lift, under the same stroke of the piston rod of the cylinder, due to the cooperation of the movable pulley 440 and the belt 420, the support bracket 200 can move twice as much as the stroke of the piston rod, i.e. compared with a single linear cylinder, the driving mechanism 400 can create a larger lifting displacement amount for the support bracket 200 in a limited installation space, efficiently utilize the space of the base frame 100, and save the installation space and installation cost of the driving mechanism 400.
