[0039] Please refer to Figures 1 to 7, this application provides a telescopic platform, including a frame 100, a first track 200, a second track 300, a telescopic frame 400 and a telescopic table 500. The frame 100 includes a cross beam 110 and a longitudinal frame 120 which are fixed to each other. Exemplarily, the cross beam 110 is arranged on the top of the longitudinal frame 120, and the length direction of the cross beam 110 is perpendicular to the length direction of the longitudinal frame 120. The first track 200 is arranged on the side of the cross beam 110 away from the longitudinal frame 120, and the frame 100 moves along the first track 200; preferably, the first track 200 is arranged at the end of the bottom side of the cross beam 110. The first track 200 serves both as a guiding device for the movement of the frame 100 and provides support for the frame 100. During installation, the first track 200 can be installed on a wall, on the steel structure of a factory building, or on other fixable structures, reducing the installation requirements, so as to meet the installation and use requirements in various scenarios. The second track 300 is arranged on the side of the longitudinal frame 120 away from the cross beam 110, the second track 300 is parallel to the first track 200, and the frame 100 moves relative to the second track 300 along the second track 300. Exemplarily, the second track 300 is arranged at the bottom of the frame 100. The second track 300 can be directly installed on the ground or in a groove dug on the ground to reduce the occupation of the factory building ground by the second track 300, facilitating the passage of workpieces or vehicles on the ground. The telescopic frame 400 is arranged on the longitudinal frame 120 and moves along the longitudinal frame 120 to meet the needs of working at different heights. The telescopic table 500 is arranged on the telescopic frame 400, and the telescopic table 500 expands and contracts in a direction perpendicular to the longitudinal frame 120. Preferably, the telescopic table 500 moves in a direction parallel to the cross beam 110, so as to meet the requirements of working at different distances from the frame 100. The telescopic platform of this application is convenient to install and does not require a fixed wall for installation, meeting the installation requirements of various factory buildings; the first track 200 of this application is installed at a high place, so when the frame 100 moves, usually only attention needs to be paid to no obstruction or blockage at the second track 300, reducing the use risk. When not in use, the frame 100 can be moved to the end of the second track 300, reducing the space occupation and improving the space utilization rate of the factory building.

[0040] Please refer to Figure 1 and Figure 4, in an embodiment of the present application, the telescopic platform includes a first driving mechanism 210, the first driving mechanism 210 is matched with the first track 200, and the first driving mechanism 210 drives the frame 100 to move along the first track 200. Exemplarily, the first driving mechanism 210 includes a first reduction motor 211 and a first driving wheel 212, and the first reduction motor 211 drives the first driving wheel 212 to move along the first track 200, thereby driving the frame 100 to move along the first track 200. Further, the first driving mechanism 210 further includes a first driven wheel, the first driven wheel and the first driving wheel 212 are respectively arranged on both sides of the bottom of the cross beam 110, and both the first driven wheel and the first driving wheel 212 are matched with the first track 200 to improve the running stability of the frame 100.

[0041] Please refer to Figure 2 and Figure 3 , in an embodiment of the present application, the first track 200 is installed on the first mounting bracket 220, which facilitates the installation and fixation of the first track 200. Side rollers 600 are provided on the cross beam 110. When the frame 100 tilts away from the first track 200, the side rollers 600 are in contact with the first track 200 or the first mounting bracket 220, so that the side rollers 600 receive a force that restricts the frame 100 from tilting away from the first track 200. When the frame 100 is at risk of tilting or overturning, the side rollers 600 are in contact with the first track 200 or the first mounting bracket 220, thereby restricting the further tilting of the frame 100, protecting the frame 100, improving the safety of using the telescopic platform, and reducing the occurrence of safety accidents.

[0042] Further, the side rollers 600 are arranged below the first mounting bracket 220, and the top of the side rollers 600 is in contact with the bottom wall of the first mounting bracket 220. When the frame 100 tilts around the length direction of the second track 300, the force exerted by the first mounting bracket 220 on the side rollers 600 can restrict the rotation of the frame 100, thereby improving safety. In other embodiments of the present application, there is a gap between the side rollers 600 and the first mounting bracket 220. When the frame 100 tilts, the side rollers move to contact the first mounting bracket 220, thereby restricting the further tilting of the frame 100 and preventing the frame 100 from overturning.

[0043] Please refer to Figure 3, in another embodiment of the present application, the first mounting bracket 220 is an orbital beam 221. The orbital beam 221 is in the shape of an I-beam, and the side rollers 600 are arranged at the bottom of the upper flange of the orbital beam 221 or at the bottom of the orbital beam 221. Exemplarily, the side rollers 600 are arranged at the bottom of the upper flange of the orbital beam 221, and there is a vertical gap between the top of the side rollers 600 and the bottom of the upper flange. The vertical gap is 1 - 15 mm, and the vertical gap can be any value between 1 - 15 mm, such as 1 mm, 5 mm, 10 mm, 15 mm, etc.; preferably, the vertical gap is 3 - 10 mm, and it can be any value between 3 - 10 mm, such as 3 mm, 6 mm, 10 mm, etc., to ensure that when the frame 100 tilts, the side rollers 600 can press against the bottom of the upper flange of the orbital beam 221 to limit the further tilt and overturn of the frame 100. Further, there is a horizontal gap between the side rollers 600 and the upper flange, and the horizontal gap is any value between 5 - 15 mm, such as 5 mm, 10 mm, 15 mm, etc. Preferably, the horizontal gap is 8 - 10 mm, such as any value between 8 - 10 mm like 8 mm, 9 mm, 10 mm, etc., which can not only avoid interference between the side rollers 600 and the upper flange but also ensure that the cooperation between the side rollers 600 and the orbital beam 221 can effectively limit the overturn of the frame 100.

[0044] Please refer to Figure 3 , exemplarily, an extension bracket 610 is fixed on the cross beam 110. The extension bracket 610 extends downward, and the side rollers 600 are rotatably connected to the extension bracket 610 so that the side rollers 600 extend into the bottom of the upper flange of the orbital beam 221 or the bottom of the orbital beam 221.

[0045] Please refer to Figure 1 and Figure 4 , in an embodiment of the present application, the telescopic platform includes a second driving mechanism 310. The second driving mechanism 310 cooperates with the second track 300 to drive the frame 100 to move along the second track 300. The second driving mechanism 310 includes a second reduction motor 311 and a second driving wheel 312. The second reduction motor 311 drives the second driving wheel 312 to roll relative to the second track 300, so that the frame 100 moves along the second track 300. Further, the second driving mechanism 310 further includes a second driven wheel. The second driven wheel and the second driving wheel 312 are arranged on both sides of the bottom of the longitudinal frame 120. The second driven wheel and the second driving wheel 312 both cooperate with the second track 300 to improve the running stability of the frame 100.

[0046] Please refer to Figure 1 、 Figure 4 and Figure 5, in an embodiment of the present application, the telescopic platform includes a third driving mechanism 410, and the third driving mechanism 410 drives the telescopic frame 400 to move up and down along the longitudinal frame 120, so as to adjust the height of the telescopic table 500 to meet the needs of working at different heights.

[0047] Please refer to Figure 4 and Figure 5 , further, the third driving mechanism 410 includes a lifting motor 411, a lead screw 412 arranged on the frame body 100, and a nut 413 arranged on the telescopic frame 400. The lifting motor 411 drives the lead screw 412 to rotate, so that the telescopic frame 400 moves along the lead screw 412, realizing the up and down movement of the telescopic table 500 to meet the usage needs at different heights. Compared with the lifting methods such as chains, the lead screw 412 - nut 413 structure can reduce the probability of the telescopic frame 400 falling, improve the safety of using the telescopic platform, and reduce the occurrence of safety accidents. Further, the lifting motor 411 is arranged on the upper part of the frame body 100.

[0048] Please refer to Figure 4 and Figure 5 , in an exemplary embodiment of the present application, the telescopic platform includes a counterweight 700. The counterweight 700 is connected to the telescopic frame 400 through a connecting rope 710. The connecting rope 710 is preferably a steel wire rope to improve durability. The connecting rope 710 passes over a fixed pulley 121 on the upper part of the longitudinal frame 120. By means of the counterweight 700, the load on the third driving mechanism 410 can be reduced, thereby reducing the design requirements of the third driving mechanism 410, lowering the production cost, and also increasing the service life of the third driving mechanism 410. Further, two connecting ropes 710 are arranged on the counterweight 700, and the two connecting ropes 710 are respectively arranged on both sides of the top of the counterweight 700 to keep the counterweight 700 balanced and reduce the risk of the counterweight 700 tilting. Two or four fixed pulleys 121 are arranged on the top of the longitudinal frame 120. Preferably, four fixed pulleys 121 are arranged. Each connecting rope 710 passes over two fixed pulleys 121, so that the distance between the two ends of the connecting rope 710 can be extended, avoiding interference between the counterweight 700 and the telescopic frame 400.

[0049] Further, the fixed pulley 121 close to the side of the counterweight 700 extends out of the longitudinal frame 120 to avoid interference and wear between the connecting rope 710 and the longitudinal frame 120.

[0050] In another embodiment of the present application, through - holes are arranged on the longitudinal frame 120, and the connecting rope 710 is accommodated to pass through the through - holes. Further, there is a gap between the connecting rope 710 and the wall of the through - hole to reduce the contact wear between the connecting rope 710 and the longitudinal frame 120 and improve the service life of the connecting rope 710.

[0051] Please refer to Figure 6 andFigure 7 In an embodiment of the present application, it includes a fourth driving mechanism 510, and the fourth driving mechanism 510 drives the telescopic table 500 to telescopically move in a direction perpendicular to the longitudinal frame 120. Preferably, the fourth driving mechanism 510 is a telescopic rod. One end of the telescopic rod is connected to the telescopic frame 400, and the other end of the telescopic rod is connected to the telescopic table 500. Thus, the telescopic movement of the telescopic rod drives the telescopic belt to relatively move with the telescopic frame 400 in a direction perpendicular to the longitudinal frame 120, realizing the movement of the telescopic table 500.

[0052] Please refer to Figure 6 and Figure 7 In an embodiment of the present application, grooves 520 are provided on both side walls of the telescopic table 500, and a plurality of fourth rollers 420 are rotatably provided on the telescopic frame 400. The fourth rollers 420 are inserted into the grooves 520, and the grooves 520 are in contact with the tops of the fourth rollers 420. The fourth rollers 420 provide support for the telescopic table 500, and the grooves 520 provide guidance for the telescopic table 500. When the telescopic table 500 moves relative to the telescopic frame 400, the fourth rollers 420 roll, so that the rolling friction exists between the telescopic table 500 and the telescopic frame 400, reducing the load of the fourth driving mechanism 510 and improving the durability of the fourth driving mechanism 510.

[0053] In an embodiment of the present application, a protective frame 800 is further provided on the telescopic table 500. The protective frame 800 is at least provided at both ends of the telescopic table 500 along the length direction of the second track 300, thereby reducing the risk of workers falling from the telescopic table 500 and reducing the occurrence of safety accidents. The protective frame 800 can be of a guardrail structure or a baffle structure, and the present application does not limit this.

[0054] Please refer to Figure 8 , Figure 8 Fig. is a schematic diagram of an exemplary telescopic platform application of the present application. In order to improve the space utilization rate of the factory building and ensure safety at the same time, the workstations 920 in the factory building are usually arranged on both sides, and a safety passage 930 is provided between the workstations 920 on both sides. The first track 200 of the telescopic platform of the present application can be installed on the erected steel frame 910, or directly installed on the steel structure of the factory building. The second track 300 is laid on both sides of the safety passage 930, thereby avoiding erecting the steel frame 910 on both sides of the safety passage 930. When the telescopic platform is needed, the frame 100 of the telescopic platform is moved to the workstation 920. When it is not in use, the frame 100 is moved to a suitable position on the second track 300, ensuring the use of the safety passage 930 and optimizing the space utilization rate of the factory building.

[0055] The utility model relates to a telescopic platform. The telescopic platform can be directly installed on the steel structure of a factory building without the need to be installed on a fixed wall, which is convenient for installation and use and reduces the occupation of space. When the telescopic platform is not in use, the frame can be moved to the end of the second track, further reducing the occupation of space and improving the space utilization rate of the factory building. Therefore, the utility model effectively overcomes some practical problems in the prior art and thus has high utilization value and practical significance. The above embodiments are only illustrative of the principles and effects of the utility model and are not intended to limit the utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the utility model should still be covered by the claims of the utility model.
