[0044] The embodiment of the utility model provides a lifting platform that is laterally hung on the main beam of a crane, such as Figures 1-12 As shown, the lifting platform side-hung on the crane main beam includes:

[0045] A lifting platform 100, wherein the lifting platform 100 includes a protective basket 110 and a scissor lift 120; the protective basket 110 is arranged on top of the scissor lift 120, and the protective basket 110 is lifted by the scissor lift 120;

[0046] The side pylon 200 includes a lifting platform base 210, a bottom frame 220, and a side frame 230. The side frame 230 is disposed on one side of the bottom frame 220 and moves to one side of the crane main beam 400. The bottom frame 220 extends from the bottom of the crane main beam 400 to the other side of the crane main beam 400. The lifting platform base 210 is disposed on a side of the bottom frame 220 away from the side frame 230. The scissor lift 120 is disposed on the lifting platform base 210.

[0047] A platform running track 510 and a limiting track 520 are provided on the crane main beam 400. A driving wheel group 240 and a driven wheel group 250 are provided on the base frame 220. The driving wheel group 240 and the driven wheel group 250 are respectively engaged with different platform running tracks 510. Hydraulic support legs 231 are provided on the base frame 220 and the side frames 230. The base frame 220 and the side frames 230 move along the crane main beam 400 by cooperating with the platform running track 510 and the limiting track 520 through the driving wheel group 240, the driven wheel group 250 and the hydraulic support legs 231.

[0048] A power module 300, which is connected to the driving wheel assembly 240 and generates power to drive the driving wheel assembly 240 along the platform running track 510; the power module 300 serves as the power source for the lifting platform hanging on the crane main beam;

[0049] In the present application, the crane main beam 400 is provided with a hydraulic support leg 231 for connecting the side pylon 200 with the platform running track 510 and the limit track 520. With the help of the hydraulic support leg 231, the platform running track 510 and the limit track 520, the side pylon 200 is stably supported. The side pylon 200 serves as the base of the lifting platform table 100 and provides a support point for the lifting platform table 100. With the help of the side pylon 200 and the crane main beam 400, the lifting platform table 100 can obtain a higher starting position. In some areas that are inaccessible to ordinary maintenance lifting equipment, the basic height provided by the crane main beam 400 is combined with the lifting function of the lifting platform table 100 itself, and the movement of the crane main beam 400 and the side pylon 200 allows the operator to reach the corresponding working surface. With the cooperation of the crane main beam 400 and the side pylon 200, the dead angles that cannot be reached by existing lifting equipment are reduced.

[0050] The protective basket 110 and the scissor lift 120 in the lifting platform 100 of the present application are prior art equipment. The protective basket 110 is composed of a railing and a bottom plate. The scissor lift 120 mainly uses hydraulic pressure as a power source to complete the lifting. Its structural principle is the same as that of the scissor hydraulic lift in the prior art, and will not be described in detail here.

[0051] As a preferred implementation in this embodiment, the driving wheel assembly 240 includes a loading column 241, a side limit plate 242, a guide wheel shaft 243, a guide wheel 244 and a transmission gear 245;

[0052] The side limiting plates 242 are arranged on both sides of the loading column 241 and are engaged with the platform running track 510. The loading column 241 is fixed on the base frame 220.

[0053] The guide wheel shaft 243 is fixed on the loading column 241, and the loading column 241 is extended from one side of the guide wheel shaft 243. The guide wheel 244 is fixedly connected to the transmission gear 245. The guide wheel 244 is assembled on the portion of the guide wheel shaft 243 extending from the loading column 241 through a bearing. The guide wheel 244 is pressed onto the platform running track 510. The guide wheel 244 is pressed onto the end surface of the platform running track 510 away from the base frame 220; the guide wheel 244 rolls on the end surface of the platform running track 510 away from the ground, which is equivalent to being engaged with the platform running track 510, thereby preventing slippage during movement.

[0054] The transmission gear 245 is meshed with the power module 300; the power module 300 generates power to drive the driving wheel group 240 to move;

[0055] The passive wheel set 250 has one less transmission gear 245 than the driving wheel set 240 , and the other structures are the same as the driving wheel set 240 . The driving wheel set 240 is directly driven by the power module 300 , and the passive wheel set 250 is equivalent to the driven structure of the driving wheel set 240 .

[0056] There are two driving wheel sets 240 and two driven wheel sets 250, and the driving wheel sets 240 and the driven wheel sets 250 are mounted on the platform running track 510 in a similar manner to a hanging rail mounting.

[0057] As a preferred implementation in this embodiment, Figure 7As shown, the hydraulic support leg 231 is provided at one end of the side frame 230 away from the base frame 220, and a slide groove is provided on the end surface of the limiting rail 520 away from the crane main beam 400. The hydraulic support leg 231 moves in the slide groove during the movement of the side frame 200. When the side frame 200 reaches a designated position and stops moving, the hydraulic support leg 231 automatically extends and abuts against the limiting rail 520 under the action of hydraulic pressure.

[0058] The side frame 230 is further provided with a reverse roller 232 at one end away from the bottom frame 220. The reverse roller 232 rolls on the end surface of the limiting rail 520 close to the bottom frame 220 to reduce friction during movement.

[0059] The base frame 220 is provided with hydraulic legs 231, and the number of the hydraulic legs 231 is four. The base frame 220 is composed of two groups of cross bars, and the side frame 230 is composed of two groups of columns. Connecting rods are provided between the columns and the cross bars; the driving wheel group 240 and the driven wheel group 250 are respectively arranged on different cross bars, and the hydraulic legs 231 are respectively assembled in groups of two on different cross bars. The connection method between the hydraulic legs 231 on one side of the driven wheel group 250 and the cross bar is as follows Figure 9 As shown, the ends of the columns away from the crossbars are also provided with hydraulic legs 231. When the side pylons 200 reach the designated position and stop moving, the hydraulic legs 231 will automatically extend and abut against the bottom of the crane main beam 400 under the action of hydraulic pressure.

[0060] In this embodiment, the hydraulic legs 231 adopt the technical principle of hydraulic push rods in the prior art and can achieve telescopic deformation under the action of hydraulic pressure. They are mainly used to abut against the crane main beam 400 when the side pylon 200 stops moving. When moving, the hydraulic legs 231 will retract to avoid affecting the movement process.

[0061] In a further preferred embodiment of the present invention, the power module 300 includes a driving mechanism 310 , a driving shaft 320 and a driving gear 330 ;

[0062] The driving mechanism 310 is assembled on the base frame 220, and the driving shaft 320 is connected to the power output shaft of the driving mechanism 310. The driving mechanism 310 here is composed of existing technologies such as a motor and a reducer. The power generated by the motor is decelerated by the reducer and transmitted to the driving shaft 320. The driving shaft 320 is assembled on two sets of driving wheel groups 240 through bearings. The driving gears 330 are also in two sets, which are respectively engaged with different transmission gears 245. The transmission gears 245 drive the guide wheel shaft 243 and the guide wheel 244 to move. The guide wheel 244 pulls the side pylon 200 along the platform running track 510 to move;
