Description

Technical Field

[0001] The present application relates to the technical field of truss track travel systems, and in particular to a hanging basket assembly platform and a drive system thereof. Background Art

[0002] A Chinese patent with authorization announcement number CN113585103B discloses a hanging basket truss and track-driven walking system based on meshing transmission, including a truss and a guide rail. The guide rail supports the truss through a front support and a rear support. The rear side of the bottom of the truss is fixed by an anchoring system. A hydraulic jack is arranged in the front support. The piston rod of the hydraulic jack is connected to a door-shaped support foot. The door-shaped support extends into the guide rail. Front hanging wheels are rotatably installed on both sides of the front support; a reducer housing is arranged in the rear support. The lower end of the reducer housing extends into the guide rail. A coaxial turbine and a pair of first gears, as well as a worm are rotatably installed in the reducer housing. The turbine is meshed with the worm. A main gear and a second gear are rotatably installed on both sides of the reducer housing in the guide rail. The second gear is meshed with the first gear; rear hanging wheels are also rotatably installed on both sides of the reducer housing.

[0003] The guide rail movement method of the above patent is: when the guide rail needs to be moved, the guide rail fastening system is removed to release the constraint between the guide rail and the beam surface, and the anchoring system is loosened to raise the truss and the rear support to drive the guide rail to rise (see Figure 7 ), the height of the guide rail is raised until the guide rail is not hindered by the embedded threaded steel pile head when moving. At this time, the rear end of the guide rail is suspended on the hanging wheel, and the main gear on the gear shaft is in normal meshing with the rack; at the same time, the front support is raised to Figure 6 state; at this point, the guide rail is completely suspended on the front and rear wheels; the hydraulic motor is controlled to rotate, and the guide rail can be driven to move through the coupling, worm, turbine, first gear, gear shaft and rack, or the guide rail can be moved by manually turning the flat square at one end of the worm with a wrench. After the guide rail is moved into place, the anchor system is tightened so that the guide rail falls on the pad but does not press the guide rail, and the hydraulic jack is controlled to make the guide rail fall onto the pad in a free state (i.e., the upper wing plate of the guide rail is not in contact with the rib plate and the front wheel), and the guide rail position can be corrected at this time. After the guide rail position is corrected, it is fixed to the beam section through the guide rail fastening system.

[0004] The truss movement method of the above patent is: the guide rail is fixed on the beam section; the anchor system is removed, and the rear hanging wheel on the rear support fixed to the truss is automatically buckled to the lower side of the upper wing plate of the guide rail I-beam track (see Figure 8 ) so that the truss maintains a balanced force; at the front end of the truss, control the piston rod of the hydraulic jack to extend so that the door-shaped support foot touches the ground and then continues to lift the front support, place the roller in the semicircular opening groove between the guide rail and the bottom surface of the front support, and then lower the front support so that the weight of the front support is pressed on the roller (see Fig. 9 , Figure 2 ), at this time, the bottom surface of the front support is not in contact with the guide rail. At this point, the front support of the truss is pressed on the guide rail by the roller, and the rear support is buckled on the guide rail by the rear hanging wheel. By controlling the rotation of the hydraulic motor, the truss can be driven to move through the coupling, worm, turbine, first gear, second gear 3, gear shaft and rack 2. The truss can also be moved by manually turning the flat square at one end of the worm with a wrench; after the truss is moved into place, first lift the front support with the hydraulic jack to remove the roller, and then put the front support completely on the guide rail.

[0005] In the above-mentioned related technical solutions, since the truss movement and the guide rail movement are both automated except for the installation and disassembly of the roller, in order to further improve the convenience, the applicant hopes to achieve the roller appearing when needed and automatically being retracted when not needed without adding additional drives, thereby realizing fully automated operation.

DETAILED DESCRIPTION

[0037] The present application is further described in detail below in conjunction with the accompanying drawings.

[0038] In the description of the present application, it should be understood that the terms "up", "down", "left", "right", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0039] A hanging basket assembly platform, such as Figure 1 As shown, it includes a truss 100, a guide rail 400, a front support 200 and a rear support 300. The guide rail 400 is fixed to the beam section 10 by an anchoring system, the front support 200 and the rear support 300 are fixed to the bottom of the truss 100, and the front support 200 and the rear support 300 are installed on the guide rail 400. When not moving, the annular ribs 210 on the front support 200 and the rear support 300 are against the upper wing plate 410 to form support.

[0040] like Figure 2 As shown, a jack 500 is provided on the front support 200, and the telescopic rod of the jack 500 is arranged downward. A support leg 510 is installed on the telescopic rod of the jack 500. After the support leg 510 is extended, it can abut against the beam section 10 to lift the front support 200, so that the annular rib plate 210 of the front support 200 is separated from the upper wing plate 410.

[0041] like Figure 2 and Figure 3 As shown, the front support 200 is provided with two horizontal slide rails 600, which are arranged in the same direction and parallel to the guide rails 400. Figure 4Horizontal slide grooves are provided on both sides of the horizontal slide rail 600, and sliders 610 are installed on the horizontal slide grooves on both sides of the horizontal slide rail 600. A sliding seat 700 is sleeved on the horizontal slide rail 600, and a vertical slide groove is provided on the sliding seat 700. The slider 610 cooperates with the vertical slide groove so that the sliding seat 700 can move up and down on the slider 610, and at the same time, the slider 610 can drive the sliding seat 700 to slide horizontally on the horizontal slide rail 600.

[0042] Reference Figure 3 A lifting member 520 is installed on the telescopic rod of the jack 500. The lifting member 520 includes a connecting rod 521 for connecting to the telescopic rod of the jack 500, and an extension rod 522 with one end connected to the connecting rod 521. Two extension rods 522 are provided and are respectively fixed to the two ends of the connecting rod 521. The extension rod 522 extends in the direction in which the connecting rod 521 slides toward the front support 200, and the sliding seat 700 is located between the two ends of the extension rod 522. When the lifting member 520 moves downward, the sliding seat 700 is driven to slide horizontally in the direction opposite to the front support 200, so that the sliding seat 700 can be located at the end of the front support 200 when supporting the front support 200.

[0043] One end of the extension rod 522 away from the connection rod 521 is rotatably connected to an elastic telescopic rod 530, and the other end of the elastic telescopic rod 530 is rotatably connected to the sliding seat 700, so that the elastic telescopic rod of the jack 500 drives the lifting member 520 to move up and down, and drives the sliding seat 700 to slide in the vertical and horizontal directions through the elastic telescopic rod 530. The elastic telescopic rod 530 is a tension rod, that is, it is relatively short in a natural state, and generates an elastic restoring force when stretched, and when the telescopic rod of the jack 500 is not extended, the elastic telescopic rod 530 is in a stretched state.

[0044] Reference Figure 4 A positioning structure is provided between the sliding seat 700 and the front support 200. The positioning structure is used to position the sliding seat 700 in the vertical direction and release the positioning when the sliding seat 700 moves horizontally. The positioning structure includes an elastic telescopic clamping column 710 provided on the sliding seat 700 and a clamping groove 720 provided on the side wall of the front support 200. The elastic telescopic clamping column 710 includes a clamping column 711 and a return spring 712. The clamping column 711 is slidably installed or plugged on the sliding seat 700. The return spring 712 allows the clamping column 711 to extend out of the sliding seat 700 in a natural state. Figure 5 A guiding inclined surface 730 is provided on one side of the card slot 720 for the elastic telescopic card column 710 to slide out of the card slot 720 .

[0045] Among them, refer to Figure 6The top height of the slot 720 is higher than the top height of the guiding slope 730, and the bottom of the slot 720 is flush with the bottom of the guiding slope 730, so that the sliding seat 700 will not move left and right when subjected to an upward force. In order to avoid the transition of the support leg 510 downward causing a partial area of ​​the card column 711 to come into contact with the guiding slope 730, which will cause the roller 800 to be unused when the support leg 510 is retracted and the roller 800 needs to be used, the top of the guiding slope 730 can be set to an inclined structure to ensure that the card column 711 can only be in the slot 720 when the roller 800 is in use.

[0046] Reference Figure 5 A limiting bolt 220 is installed on the inner wall of the front support 200. By adjusting the limiting bolt 220, when the sliding seat 700 is against the limiting bolt 220, the elastic telescopic clamping column 710 and the clamping slot 720 are located in the same vertical direction.

[0047] like Figure 2 As shown, a roller 800 is arranged below the sliding seat 700 , and two rollers 800 are provided, and a rotating shaft between the two rollers 800 is rotatably connected to the sliding seat 700 .

[0048] like Figure 2 and Figure 7 As shown, a damping positioning mechanism 900 is provided on the sliding track of the sliding seat 700 so that the sliding seat 700 can only pass in one direction when sliding to the lowest position of the slider 610. The damping positioning mechanism 900 includes a mounting seat 910, a block 920 slidably mounted in the mounting seat 910, and an elastic reset member 930 provided at the bottom of the block 920. The mounting seat 910 is located on the side wall of the front support 200 and is located in the guide rail 400.

[0049] Reference Figure 7 A guiding slope 921 is provided on one side of the building block 920, and a guiding angle 922 is provided on the other side. The figure shows the state when the sliding seat 700 slides to the top on the slider 610. At this time, the bottom of the sliding seat 700 is lower than the bottom of the building block 920, but higher than the bottom of the guiding angle 922.

[0050] Working principle:

[0051] When the roller 800 needs to be used, when the support leg 510 moves downward, the elastic telescopic rod 530 is first contracted, and after contracting to a certain extent, because the elastic tension of the elastic telescopic rod 530 is less than or equal to the gravity of the sliding seat 700, the sliding seat 700 moves downward in the vertical direction along the slider 610 under the action of gravity, and the positioning structure is matched before moving down to the bottom. At this time, the annular rib plate 210 on the front support 200 is separated from the upper wing plate 410, and the roller 800 extends the annular rib plate 210 downward. For details, see the attached Fig. 9At this time, when the jack 500 drives the support leg 510 to reset, the sliding seat 700 will remain in position under the action of the positioning structure, that is, when the support leg 510 retracts, the roller 800 abuts against the upper wing plate 410 of the guide rail 400, and then subsequent operations can be performed to move the truss 100.

[0052] When the drum 800 needs to be retracted, the support leg 510 is moved down again or Fig. 9 In the process of continuing to move downward to the bottom in the middle state, the sliding seat 700 moves horizontally through the block 920 of the damping positioning mechanism 900 and releases the positioning structure to form an attached Fig.10 Then the support leg 510 is reset, and the sliding seat 700 is blocked by the block 920, so that the elastic telescopic rod 530 is stretched, and after the stretching force reaches a certain level, the stretching force is greater than the weight of the sliding seat 700, thereby driving the sliding seat 700 to slide downward on the slider 610, reaching Figure 8 At this time, when the support leg 510 is reset and continues to reset, the tensile force will pull the sliding seat 700 to move to the right, and the building block 920 is compressed to release the one-way lock of the damping positioning mechanism 900, and under the tensile force of the elastic telescopic rod 530, the sliding seat 700 is driven to slide and reset, and the clamping column 711 on the sliding seat 700 is kept above the clamping slot 720 under the tensile force.

[0053] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
