Description

[Technical Field]

[0001] The present application relates to the technical field of truss track traveling systems, and in particular to a sling car assembly platform and its drive system. [Background technology]

[0002] Chinese patent publication number CN113585103B discloses a cage truss and track-driven travel system based on meshing transmission, including a truss and a guide rail. The guide rail supports the truss via front and rear mounts, and the rear end of the truss is fixed by an anchor system. A hydraulic jack is located within the front mount, with the hydraulic jack's piston rod connected to a door-shaped support leg that extends into the guide rail. Front lifting rings are rotatably mounted on both sides of the front mount. A reducer housing is also located within the rear mount, with the lower end of the reducer housing extending into the guide rail. A coaxial turbine and a pair of first gears and worms are rotatably mounted within the reducer housing. The turbine and worm mesh, and a main gear and a second gear are rotatably mounted on both sides of the reducer housing within the guide rail, respectively, with the second gear engaging the first gear. Rear lifting rings are also rotatably mounted on both sides of the reducer housing.

[0003] The patent's guide rail movement method is as follows: When the guide rail needs to be moved, the guide rail fastening system is disassembled to release the constraint between the guide rail and the beam surface. The anchor system is then loosened, and the truss and rear mount are raised, which then raises the guide rail (see Figure 7 of the patent). The guide rail continues to rise until it is no longer obstructed by the embedded threaded steel pile heads. At this time, the rear end of the guide rail is suspended from the suspension ring, and the main gear and rack on the gear shaft are in normal engagement. At the same time, when the front mount is raised to the state shown in Figure 6 of the patent, the guide rail is fully suspended from the front and rear suspension rings. The guide rail can be moved by controlling the rotation of the hydraulic motor using a coupling, worm, turbine, first gear, gear shaft, and rack, or by using a wrench to artificially rotate one end of the worm shaft. After the guide rail is moved to the appropriate position, the anchor system is tightened to drop the guide rail onto the pad block, but without compressing the guide rail. Also, the hydraulic jack is controlled to drop the guide rail onto the pad block and leave it free (i.e., the upper wing of the guide rail does not come into contact with the rib plate or the front lifting ring). At this time, the position of the guide rail is corrected, and then the guide rail is fixed to the beam segment by the guide rail tightening system.

[0004] The truss movement method in the patent is as follows: The guide rail is fixed to the beam segment. When the anchor system is dismantled, the rear lifting ring of the rear mount, which is fixed to the truss, automatically connects to the underside of the upper wing of the U-shaped rail of the guide rail (see Figure 8 of the patent), allowing the truss to maintain balance of force. At the end of the truss, the piston rod of the hydraulic jack is controlled to extend, and when the door-shaped support foot touches the ground, the front mount is pushed up again. At this time, rollers are placed in the semicircular locking grooves between the guide rail and the bottom of the front mount, and the front mount is lowered so that the front mount presses its weight against the rollers (see Figures 9 and 2 of the patent). At this time, the bottom of the front mount does not contact the guide rail. In this way, the front mount of the truss presses its weight against the guide rail through the rollers, while the rear mount connects to the guide rail through the rear lifting ring. By controlling the rotation of the hydraulic motor, the movement of the truss can be driven by the coupling, worm, turbine, first gear, second gear 3, gear shaft and rack, etc., or the movement of the truss can be achieved by artificially rotating one end of the worm using a wrench. After the truss has moved to the appropriate position, the front mount is pushed up with a hydraulic jack to remove the rollers, and the front mount is placed completely on the guide rail.

[0005] In the related art described above, in addition to the placement and removal of rollers, the movement of the truss and the movement of the guide rails are already automated. Therefore, in order to further improve convenience, an attempt is made to achieve complete automation by allowing the rollers to appear when needed and automatically retract when not needed, assuming there is no additional driving. Summary of the Invention [Problem to be solved by the invention]

[0006] To realize fully automated truss movement and guide rail movement, the present application provides a drive system for the cage assembly platform. [Means for solving the problem]

[0007] First, the present application provides a driving system for a cage assembly platform, which adopts the following technical solution:

[0008] A drive system for a cage assembly platform includes a guide rail and a front mount and a rear mount fixed to a truss, the front mount and the rear mount are attached to the guide rail, a jack and a support foot attached to the jack are installed on the front mount, a horizontal slide rail is provided within the front mount, a slider is attached to the horizontal slide rail, and a slide sheet is attached to the slider so as to slide along a direction perpendicular to the horizontal slide rail. Furthermore, a lifting member is attached to a telescopic rod of the jack, and the lifting member and the slide sheet are connected by an elastic telescopic rod.

[0009] A positioning structure for vertically positioning the sliding sheet is installed between the sliding sheet and the front mount, and the positioning is released when the sliding sheet moves horizontally. A roller is installed below the sliding sheet. Furthermore, a damping positioning mechanism is installed in the sliding track of the sliding sheet to limit the sliding sheet to one-way movement when the sliding sheet slides to the lowest position of the slider.

[0010] When the support leg moves downward, the elastic telescopic rod contracts to a certain extent, causing the slide sheet to move downward and the slider to the bottom, where the positioning structure engages. At this time, the annular rib plate of the front mount, which resists the upper wing plate of the guide rail, separates from the upper wing plate, and the roller pushes the annular rib plate downward.

[0011] As the support foot continues to move downward, the slide seat moves horizontally, is released from position, and passes through the damping positioning mechanism.

[0012] When the support leg is reset, the sliding sheet is blocked by the damping positioning mechanism, which pulls the elastic telescopic rod. After the pulling force reaches a certain level, the one-way lock of the damping positioning mechanism is released. The pulling force of the elastic telescopic rod then lifts the sliding sheet and the slider, and slides the slider and the sliding sheet to reset.

[0013] In one embodiment, the positioning structure includes an elastic elastic locking post installed on the sliding seat and a locking groove installed on the side wall of the front mount, with a guide slope on one side of the locking groove to guide the elastic elastic locking post out of the locking groove.

[0014] In one embodiment, a limit bolt is attached to the inner wall of the front mount, and when the sliding seat abuts against the limit bolt, the elastic expansion and contraction locking post is positioned in the same vertical direction as the locking groove.

[0015] In one embodiment, the top of the locking groove is higher than the top of the guide inclined surface.

[0016] In one embodiment, the slider is disposed between a horizontal slide rail and a slide sheet, the horizontal slide rail is provided with a horizontal chute along which the slider slides, and the slide sheet is provided with a vertical chute along which the slider slides.

[0017] In one embodiment, the damping positioning mechanism includes a mounting seat, a block slidably mounted within the mounting seat, and a resilient reset member mounted at the bottom of the block.

[0018] In one embodiment, one side of the block is provided with a guide bevel and the other side is provided with a guide bevel angle, whereby when the sliding sheet slides to the top of the slider, the bottom of the sliding sheet is lower than the bottom of the block and higher than the bottom of the guide bevel angle.

[0019] In one embodiment, the mounting seat is located on a side wall of the front mount and within the guide rail.

[0020] In one embodiment, the lifting member includes a connecting rod connected to the telescopic rod of the jack and an extension rod connected at one end to the connecting rod, the extension rod extending in a direction in which the connecting rod slides toward the front mount, and the sliding seat is positioned between both ends of the extension rod.

[0021] Secondly, the present application provides a cage assembly platform that adopts the following technical solution:

[0022] A cage assembly platform including the drive system described above. [Effects of the Invention]

[0023] From the above, the present application has the following beneficial effects.

[0024] When the truss needs to be moved, if the jack pushes up the front mount and does not reach its maximum extension distance, the roller is extended downward and fixed with the positioning structure, and the jack is then retracted, causing the roller to come into contact with the guide rail and allowing the truss to move, achieving full automation without the need for an additional drive source.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The present application will now be described in more detail with reference to the accompanying drawings.

[0027] In the description of this application, the orientations or positional relationships indicated by terms such as "upper," "lower," "left," and "right" are based on the orientations or positional relationships shown in the drawings and are intended merely to facilitate and simplify the description of this application, and do not indicate or imply that the devices or elements referred to have a particular orientation or must be configured and operate in a particular orientation, and should not be understood as limiting this application.

[0028] As shown in Figure 1, this is a cage assembly stand comprising a truss 100, a guide rail 400, a front mount 200, and a rear mount 300. The guide rail 400 is fixed to a beam segment 10 by an anchor system, and the front mount 200 and rear mount 300 are fixed to the bottom of the truss 100, and the front mount 200 and rear mount 300 are attached to the guide rail 400. When not moving, the annular rib plates 210 of the front mount 200 and rear mount 300 abut against the upper wing plate 410 to provide support.

[0029] 2, a jack 500 is installed on the front mount 200, with the telescopic rod of the jack 500 facing downward. In addition, a support leg 510 is attached to the telescopic rod of the jack 500. When the support leg 510 extends, it abuts against the beam segment 10, pushing up the front mount 200 and separating the annular rib plate 210 of the front mount 200 from the upper wing plate 410.

[0030] 2 and 3, two horizontal slide rails 600 are installed inside the front mount 200, and the horizontal slide rails 600 are installed in the same direction as the guide rails 400 and parallel to each other. As shown in FIG. 4, horizontal chutes are provided on both sides of the horizontal slide rails 600, sliders 610 are attached to the horizontal chutes on both sides of the horizontal slide rails 600, and slide sheets 700 are placed on the horizontal slide rails 600, and vertical chutes are installed on the slide sheets 700. The sliders 610 are fitted into the vertical chutes, allowing the slide sheets 700 to move up and down, and at the same time, the sliders 610 can slide the slide sheets 700 horizontally along the horizontal slide rails 600.

[0031] 3, an elevating member 520 including a connecting rod 521 connected to the telescopic rod of the jack 500 and an extension rod 522 connected at one end to the connecting rod 521 is attached to the telescopic rod of the jack 500. Two extension rods 522 are installed, and each is fixed to both ends of the connecting rod 521. The extension rods 522 extend in the direction in which the connecting rod slides toward the front mount 200, and a sliding sheet 700 is positioned between both ends of the extension rods 522. When the elevating member 520 moves downward, the sliding sheet 700 is driven to slide horizontally in the direction opposite to the front mount 200.

[0032] An elastic telescopic rod 530 is rotatably connected to one end of the extension rod 522 remote from the connecting rod 521, and the other end of the elastic telescopic rod 530 is rotatably connected to the sliding sheet 700. As the telescopic rod of the jack 500 moves the lifting member 520 up and down, the sliding sheet 700 slides vertically and horizontally via the elastic telescopic rod 530. The elastic telescopic rod 530 is a tension rod, i.e., it is short in its natural state and generates an elastic restoring force when tensioned. When the telescopic rod of the jack 500 is not extended, the elastic telescopic rod 530 is in a tensioned state.

[0033] Referring to FIG. 4, a positioning structure is installed between the sliding sheet 700 and the front mount 200 to position the sliding sheet 700 vertically. When the sliding sheet 700 moves horizontally, the positioning is released. The positioning structure includes an elastically expandable locking post 710 installed on the sliding sheet 700 and a locking groove 720 installed on the side wall of the front mount 200. The elastically expandable locking post 710 includes a locking post 711 and a return spring 712. The locking post 711 is slidably attached to or directly inserted into the sliding sheet 700. The return spring 712 allows the locking post 711 to naturally protrude outside the sliding sheet 700. Referring to FIG. 5, a guide slope 730 is installed on one side of the locking groove 720 to allow the elastically expandable locking post 710 to slide out of the locking groove 720.

[0034] 6 , the top of the locking groove 720 is higher than the top of the guide inclined surface 730, and the bottom of the locking groove 720 is flush with the bottom of the guide inclined surface 730, preventing the sliding sheet 700 from moving left and right when an upward force is applied. In addition, if the support foot 510 is lowered too far and a part of the locking post 711 comes into contact with and fits into the guide inclined surface 730, which would require the roller 800 to return to its original position, the top of the guide inclined surface 730 is configured to have an inclined structure to ensure that the locking post 711 is only within the locking groove 720 when the roller 800 is in use.

[0035] 5, a limit bolt 220 is attached to the inner wall of the front mount 200. By adjusting the limit bolt 220, when the sliding seat 700 abuts against the limit bolt 220, the elastic expandable locking post 710 is positioned in the same vertical direction as the locking groove 720.

[0036] As shown in FIG. 2, two rollers 800 are installed under the sliding sheet 700, and the rotation axis between the rollers 800 is rotatably connected to the sliding sheet 700.

[0037] 2 and 7, a damping positioning mechanism 900 is installed on the sliding path of the sliding sheet 700 to allow the sliding sheet 700 to pass through only one way when it slides to the lowest position of the slider 610. The damping positioning mechanism 900 includes a mounting sheet 910, a block 920 mounted so as to be able to slide inside the mounting sheet 910, and an elastic reset member 930 provided at the bottom of the block 920. The mounting sheet 910 is disposed on the side wall of the front mount 200 and is also disposed within the guide rail 400.

[0038] 7, a guide bevel 921 is provided on one side of a block 920, and a guide bevel angle 922 is provided on the other side. The drawing shows the state in which the sliding sheet 700 slides the slider 610 to the top. At this time, the bottom of the sliding sheet 700 is lower than the bottom of the block 920 and higher than the bottom of the guide bevel angle 922.

[0039] The working principle is as follows:

[0040] When the roller 800 is used, as the support foot 510 moves downward, the elastic telescopic rod 530 first contracts to a certain extent. Because the elastic tensile force of the elastic telescopic rod 530 is less than the gravity of the sliding sheet 700, the sliding sheet 700 moves vertically downward along the slider 610 due to gravity, engaging the positioning structure before reaching the bottom. At this time, the annular rib plate 210 of the front mount 200 is separated from the upper wing plate 410, and the roller 800 extends the annular rib plate 210 downward, as shown in FIG. 9 . When the jack 500 resets the support foot 510, the sliding sheet 700 maintains its position through the positioning structure, i.e., as the support foot 510 contracts, the roller 800 abuts against the upper wing plate 410 of the guide rail 400. In this way, the subsequent operation can be performed to move the truss 100.

[0041] When the roller 800 needs to be retracted, the support foot 510 moves downward again, or continues to move downward while remaining in the state shown in FIG. 9. As the support foot 510 resets, the sliding sheet 700 passes through the block 920 of the damping and positioning mechanism 900, releasing the positioning of the positioning structure, resulting in the state shown in FIG. 10. Then, the support foot 510 resets, and the sliding sheet 700 is blocked by the block 920, pulling the elastic telescopic rod 530. The pulling force reaches a certain point and becomes greater than the weight of the sliding sheet 700, causing the sliding sheet 700 to slide further down the slider 610, resulting in the state shown in FIG. 8. As the support foot 510 continues to reset, the pulling force pulls the sliding sheet 700 to the right, compressing the block 920 and releasing the one-way lock of the damping and positioning mechanism 900. The pulling force of the elastic telescopic rod 530 slides the sliding sheet 700 back to its original position, and the pulling force also holds the locking post 711 of the sliding sheet 700 above the locking groove 720.

[0042] The embodiments in the means for carrying out the present invention are all preferred embodiments of the present application and do not limit the protection scope of the present application, so that any equivalent modifications made according to the structure, shape and principle of the present application should be included in the protection scope of the present application.
