[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 As shown, the embodiment of the utility model proposes a high-rise building construction lifting device, including a base 1, a workbench 4 and a horizontal rod 8. A moving wheel 2 is provided at the bottom of the base 1, a hydraulic support 3 is provided at the top of the base 1, the workbench 4 is horizontally arranged on the top of the hydraulic support 3, and a plurality of support columns 5 are provided on the four sides of the top of the workbench 4. Slots are provided on both sides of the workbench 4, and extension platforms 6 are slidably provided in the slots. A fence 7 is provided at one end of each extension platform 6 away from the workbench 4. There are two horizontal rods 8, and the two horizontal rods 8 are horizontally arranged at both ends of the workbench 4 through the support columns 5. A slide groove is provided at both ends of each horizontal rod 8, and a slide rod 9 is slidably provided in each slide groove. Each slide rod 9 is provided with a fence component for protecting workers standing on the extension platform 6. During operation, the device moves to a predetermined position via the moving wheels 2, and the worker stands on the workbench 4, then starts the hydraulic support 3, which lifts the workbench 4 to a certain height, and the worker can then carry out construction work at this height. When the area to be worked on exceeds the range of the workbench 4, the extension platform 6 is made to slide out of the slot by pushing the enclosure 7, and then the slide bars 9 on the two horizontal bars 8 are pulled to slide the slide bars 9 out of the slide grooves of the horizontal bars 8, so that the fence components on each slide bar 9 enclose both sides of the portion of the extension plate extending out of the slide groove, so that the worker is protected by the fence components and the enclosure 7 when standing on the extension plate to work, and will not fall from the extension platform 6, thereby ensuring the worker's life safety.

[0020] like Figure 1—3, further, each fence assembly includes: a blocking rod 10, each blocking rod 10 is slidably set on the corresponding sliding rod 9, a mounting groove is provided at the bottom end of each blocking rod 10, a plug rod 11 is slidably set in each mounting groove, and a plug hole 12 for inserting the plug rod 11 is provided on the extension plate. After the sliding rod 9 is pulled out of the sliding groove on the horizontal rod 8, the blocking rod 10 is slid again, and the plug rod 11 at the bottom end of each blocking rod 10 is inserted into the plug hole 12 on the extension platform 6. In this embodiment, the plug holes 12 on the extension platform 6 are arranged at equal intervals, so that after the blocking rod 10 on the same sliding rod 9 is connected to the plug hole 12 of the extension platform 6 through the plug rod 11, the blocking rods 10 are also arranged at equal intervals, thereby providing more comprehensive protection for the workers and limiting the arbitrary sliding of the extension platform 6. When the extension platform 6 is not needed, the sliding rod 9 is retracted into the sliding groove, and multiple blocking rods 10 are slid together.

[0021] like Figure 2 —3, further, it also includes: a pull rod 13, a through slot 14 connected to the installation slot is opened on the side wall of each blocking rod 10, and the pull rod 13 is provided on the side wall of each insertion rod 11, and the end of each pull rod 13 away from the insertion rod 11 passes through the corresponding through slot 14. In this embodiment, each through slot 14 is facing one side of the workbench 4, which is convenient for workers to operate the pull rod 13. In order to facilitate lifting the insertion rod 11, that is, to retract the insertion rod 11 into the installation slot, the insertion rod 11 can be lifted by pulling the pull rod 13 upwards, so that the insertion rod 11 is separated from the insertion hole 12, so that it does not hinder the sliding of the extension platform 6.

[0022] like Figure 2 As shown, further, a limiting groove 15 is provided on one side of each through groove 14 and is in an L-shape. In order to prevent the insertion rod 11 from sliding out of the mounting groove of the blocking rod 10 under the action of gravity when the insertion rod 11 is not in use, the L-shaped limiting groove 15 is provided, and the pull rod 13 is rotated at a certain angle so that the pull rod 13 is inserted into the limiting groove 15, thereby preventing the pull rod 13 from moving downward, thereby preventing the insertion rod 11 from sliding out of the mounting groove and abutting against the workbench 4.

[0023] like Figure 3 As shown, further, one end of a spring 16 is fixed in each mounting groove, and the other end of the spring 16 abuts against the insertion rod 11. In order to prevent the insertion rod 11 from being easily dislodged when inserted into the insertion hole 12, the spring 16 is provided to push the insertion rod 11 to move vertically downward, so that the insertion rod 11 is always inserted into the insertion hole 12.

[0024] like Figure 1As shown, further, a rain shelter 17 is included, and top rods 18 are fixedly mounted on the tops of the support columns 5 on both sides of the workbench 4, and the rain shelter 17 is mounted between the two top rods 18. The rain shelter 17 can provide rain or sun protection for the workers on the workbench 4, so that the workers can complete emergency operations without interference even in rainy days or under the scorching sun.

[0025] like Figure 1 As shown, further, each of the two ends of each top rod 18 is provided with a storage groove, each storage groove is slidably provided with a mounting rod 19, and a shielding cloth 20 is slidably provided on the opposite sides of the two mounting rods 19 on the same side through hooks, and one end of each mounting rod 19 away from the top rod 18 is connected to the enclosure 7 through a connecting rod 21. Specifically, a plurality of hooks are connected to both ends of the shielding cloth 20, and the hooks are arranged at intervals, and each hook is slidably connected to the mounting rod 19, so that the shielding cloth 20 can be unfolded when necessary, and the shielding cloth 20 can be stored together when the shielding cloth 20 is not needed. When the extension platform 6 is needed, in order to shade the workers on the extension platform 6 from the sun and rain, when the extension platform 6 is extended, the enclosure 7 fixed on the extension platform 6 will drive the mounting rod 19 to extend through the connecting rod 21, so that the shielding cloth 20 between the two mounting rods 19 is unfolded, thereby shading the workers on the extension platform 6 from the sun and rain, so that the workers are not disturbed by the outside world when working on the extension platform 6.

[0026] like Figure 1 As shown, further, each slide bar 9 is threadedly connected to a locking plate 22 at one end away from the horizontal rod 8. The locking plate 22 is threadedly connected to the slide bar 9, so that the blocking rod 10 sliding on the slide bar 9 can be removed for replacement, maintenance or cleaning after the locking plate 22 is removed.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
