Description

Technical Field

[0002] Many existing buildings are steel structure frameworks. After the building framework is installed, it is necessary to build or spray the side walls on the outer peripheral side of the building framework, or install prefabricated side walls, and then hoist the roof panels to the upper part of the building framework for sealing.

[0003] In the prior art, basically, the roof panels are hoisted to a certain height above the roof by a hoisting frame, and then manually positioned and installed. When using a hoisting frame for installation, it is necessary to initially set the hoisting frame on the side of the roof, first pull the roof panel to a certain height through ground assistance, and then pull the roof panel to an appropriate position for fixed installation by another hoisting frame. First, the one-by-one installation is time-consuming and laborious. Second, during the process of pulling the roof panel, the side of the roof panel and the steel structure framework slides hard in a single line, which may cause deformation and damage to the relatively thin roof panel.

Detailed implementation mode

[0044] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0045] When this embodiment is in use, the middle top beam of the building frame is set as an I-beam or an I-shaped track is arranged below the middle top beam, and the traveling mechanism is installed inside the I-shaped track to facilitate the traveling of this hoisting pulley.

[0046] As Figures 1-3 shown, a hoisting pulley for reverse installation of roof panels in this embodiment includes a pulley frame body 100. A hollow middle beam 200 is provided in the middle of the pulley frame body 100, and further includes:

[0047] A traveling mechanism 300, arranged on the top of the middle beam 200, for driving the hoisting pulley to travel; under the regulation of the control unit, the traveling mechanism 300 travels a corresponding distance after installing each section of the roof panel for hoisting the next section of the roof panel;

[0048] A pulling mechanism 400, arranged on the top of the middle beam 200, is drivingly connected to the traveling mechanism 300, for pulling the roof panel. After the roof panel is pulled in place, workers can position and install the roof panel;

[0049] A sliding support mechanism 500, arranged on both sides of the pulley frame body 100, for slidingly supporting the roof panel. The roof panel can slide on this mechanism, which can protect the roof panel.

[0050] A synchronization mechanism 600, arranged between the sliding support mechanism 500 and the pulling mechanism 400, for driving the sliding support mechanism 500 and the pulling mechanism 400 to act cooperatively to hoist the roof panel.

[0051] This embodiment should also include a control unit for controlling the coordinated actions of each mechanism in this embodiment. A total of two driving motors 320 are provided on both sides of the middle beam 200 in this embodiment, respectively driving a set of the above-mentioned traveling mechanism 300, pulling mechanism 400, sliding support mechanism 500 and synchronization mechanism 600 to act, and two roof panels can be hoisted in reverse at the same time, improving the hoisting efficiency.

[0052] Basic principle of this embodiment: The traveling mechanism 300 is used for the traveling of the integral hoist, the pulling mechanism 400 is used for pulling the roof panel, the sliding support mechanism 500 is used for supporting the roof panel to reduce the probability of damage to the roof panel, and the synchronization mechanism 600 is used to synchronously drive the pulling mechanism 400 and the sliding support mechanism 500, which can reduce the setting of power mechanisms, has a certain linkage, and the structural design is ingenious.

[0053] The traveling mechanism 300 therein includes a mounting plate 310 disposed on the top of the intermediate beam 200; a driving motor 320 mounted on the mounting plate 310 and drivingly connected to the sliding support mechanism 500 and the pulling mechanism 400; traveling wheels 330 drivingly connected to the output shaft of the driving motor 320 through an electric clutch 450 with a locking function for the traveling of the integral hoisting trolley. Four traveling wheels 330 can be provided, with two on each side, respectively disposed on both sides of the I-shaped track. One of them is connected to the output shaft of the driving motor 320 as the driving wheel, and the other is the driven wheel.

[0054] As Figure 2 shown, it can also be set as follows. A total of six traveling wheels 330 are provided, with three on each side of the I-shaped track. The driving wheel is disposed in the middle, and the two driven wheels are respectively disposed on both sides of the driving wheel. In this way, the balance of the hoist frame 100 can be better ensured, preventing the hoist frame 100 from deflecting. The driving motor 320 is mounted on the mounting plate 310. By driving the driving motor 320, the traveling wheels 330 can be driven to rotate, thereby driving the entire trolley to move.

[0055] The pulling mechanism 400 therein includes: a split drum connected to the output shaft of the driving motor 320 for winding the first steel wire rope 420 to pull the roof panel and winding the second steel wire rope 440 to drive the sliding support mechanism 500. The split drum can simultaneously wind the first steel wire rope 420 for pulling the roof panel and the second steel wire rope 440 for driving the sliding support mechanism 500. Through the above two driving motors 320, the coordinated actions of the two mechanisms can be synchronously completed.

[0056] The sliding support mechanism 500 therein includes: side columns 510 disposed on the sides of the hoist frame 100 and hollow inside; moving columns 520 slidably disposed inside the side columns 510 and provided with teeth on the inner sides thereof; rolling support components disposed on the tops of the moving columns 520 for rollingly supporting the roof panel. The side columns 510 are hollow inside, and the moving columns 520 and the rolling support components can be installed therein. The rolling support components are used to support the roof panel to reduce the hard friction of the roof panel and cause damage to it.

[0057] The synchronization mechanism 600 in this embodiment includes: a synchronization component disposed inside the side column 510 for driving the moving column 520 to move upward to roll and support the roof panel; a steering component for connecting with the second steel wire rope 440 and driving the synchronization component to act. The synchronization component is disposed inside the side column 510 and can cause the moving column 520 to move upward under the pulling of the second steel wire rope 440.

[0058] The split drum in this embodiment includes: a first drum 410 for winding the first steel wire rope 420 to pull the roof panel; a second drum 430 connected to the output shaft of the driving motor 320 through an electric clutch 450 with a locking function for winding the second steel wire rope 440 to pull the sliding support mechanism 500. The first drum 410 and the second drum 430 can rotate relatively, and the rotation and relative stop of the second drum 430 can be controlled through the electric clutch 450 with a locking function. For example, in the initial stage of hoisting, through the control of the electric clutch 450, the second drum 430 can be non-rotating, and the first drum 410 rotates to drive the first steel wire rope 420 to rotate, which can pull the roof panel towards the roof. When the roof panel is basically parallel to the roof, at this time, through the control of the electric clutch 450, the second drum 430 can be made to rotate, so that the rolling support component can be driven by the second steel wire rope 440 to perform rolling support on the roof panel.

[0059] For the convenience of adjustment, this embodiment further includes: an adjustment mechanism 700 disposed on both side edges of the sliding frame body 100 for adjusting the position of the side column 510 relative to the sliding frame body 100; the side column 510 is slidably disposed at the middle position on the side edge of the sliding frame body 100 and is connected to the adjustment mechanism 700. The adjustment mechanism 700 can adjust the position of the side column 510 relative to the sliding trolley, so that the roof panel can be roll-supported according to actual needs.

[0060] The adjustment mechanism 700 therein includes: a sliding groove 710 disposed in the middle of the sliding frame body 100 for slidably mounting the side column 510. The sliding groove 710 is preferably a wedge-shaped groove capable of limiting the side column 510, a fixing plate 720 disposed on the side edge of the sliding frame body 100 for threadedly connecting an adjustment screw rod 730; the adjustment screw rod 730 is threadedly penetrated through the fixing plate 720, and its end is connected to the side column 510 through a sliding sleeve 740. By adjusting the adjustment screw rod 730, the side column 510 can be pulled to move within the sliding groove 710, thereby changing the position of the side column 510 on the sliding frame body 100 to adapt to the support of the roof panel.

[0061] The rolling support component therein includes: a connecting frame 530, arranged on the top of the moving column 520, on which a plurality of support rollers 540 are rotatably arranged for rolling and supporting the roof panel. The connecting frame 530 is used to connect with the moving column 520. By arranging the support rollers 540, when the moving column 520 moves upward, the support rollers 540 can be driven to move upward, so that the roof panel can slide thereon, avoiding damage to the roof panel caused by single-line hard friction, and the roof panel can be hoisted protectively.

[0062] The synchronization component therein includes: a transmission rack 610, slidably arranged in the side column 510, and its lower end is connected to the second steel wire rope 440; a conversion gear 620, rotatably installed inside the side column 510, which meshes with the transmission rack 610 and the moving column 520. By pulling the transmission rack 610 downward through the second steel wire rope 440, the moving column 520 can be driven to move upward through the conversion gear 620, and the roof panel can be supported by rolling by driving the support rollers 540 upward. In this embodiment, both the moving column 520 and the transmission rack 610 are limited by a limit slide rail 630 so that they can only move up and down reciprocally, ensuring the accuracy of transmission.

[0063] The steering component therein includes: a conversion wheel 640, rotatably arranged inside the sliding frame body 100 for winding the second steel wire rope 440. By arranging the conversion wheel 640, the friction on the second steel wire rope 440 can be reduced, making the movement of the second steel wire rope 440 smoother.

[0064] To improve the safety of operation, this embodiment further includes a protective grille 800, arranged on the periphery of the sliding frame body 100. The above-mentioned protective grille 800 is provided on the four peripheral sides of the sliding frame body 100, which can play a protective role and improve the safety of operation.

[0065] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
