DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, exemplary embodiments of the present invention are described only by way of illustration. It is undoubted that one of ordinary skill in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0025] like Figures 1 to 10As shown together, the large steel structure turnover tooling includes a base 1, which is a carrier of other structures in this embodiment. It can be fixed on the ground or other bodies for use. The fixing method can be selected by bolt fixing or welding fixing according to needs, and there is no limitation here. This embodiment only illustrates one of the bolt fixing methods.

[0026] A transfer mechanism 2 is installed above the base 1, and the transfer mechanism 2 is a conveying mechanism used to support the steel components and then transfer them to the specified position; the transfer mechanism 2 described in this embodiment includes a transfer bracket 21, and a driving sprocket 22 and a tensioning sprocket 23 are installed on the transfer bracket 21. A transfer chain 24 for transferring steel components is jointly installed on the driving sprocket 22 and the tensioning sprocket 23, and a transfer support 25 is fixedly provided on the transfer bracket 21 below the upward section of the transfer chain 24; a transfer driver 26 is provided between the driving sprocket 22 and the transfer bracket 21, and a tensioner 27 is provided between the tensioning sprocket 23 and the transfer bracket 21.

[0027] The transfer chain 24 is tensioned by using the tensioner 27. After the transfer chain 24 supports the steel component, the transfer driver 26 drives the drive sprocket 22 to rotate, and the transfer chain 24 drives the steel component to start moving. During the movement, the transfer platform 25 can provide rigid support, so that the transfer chain 24 can complete the bearing and transfer of the steel component. After being transferred to the specified position, the transfer driver 26 stops driving to complete the transfer work.

[0028] The transfer driver 26 includes a motor and a reducer, etc., and the tensioner 27 includes a tensioning seat, and a tensioning bolt between the tensioning seat and the tensioning sprocket 23, etc., which are all easily obtained by those skilled in the art in combination with conventional technical means, and are not described in detail here. The transfer bracket 21 described in this embodiment is directly made of a square tube, and the two ends of the square tube are adapted to the holes and grooves for processing and installation of sprockets, etc. After the transfer chain 24 is installed, its upward section is located on the upper part of the square tube, and the upper wall of the square tube is used to form the transfer support 25, thereby simplifying the manufacturing and assembly process of the transfer mechanism 2.

[0029] At least two lifting transmission mechanisms 3 are installed between the transfer mechanism 2 and the base 1 and are arranged in sequence along the transfer direction. The lifting transmission mechanism 3 performs lifting transmission and uses its own load-bearing capacity to support the entire lifting process of the transfer mechanism 2, thereby enabling the transfer mechanism 2 to adapt to the transfer of large steel components. The number of the lifting transmission mechanisms 3 can be flexibly set according to the transfer distance, load-bearing requirements, etc., and six are illustrated in this embodiment.

[0030] The lifting transmission mechanism 3 includes a support transmission frame 31 and a drive transmission frame 32 which are hingedly connected in the middle, that is, the support transmission frame 31 and the drive transmission frame 32 form an X-shaped structure with a changeable cross angle. The lower end of the support transmission frame 31 is hingedly connected to the base 1 and the upper end is arranged against the bottom of the transfer mechanism 2. A lifting drive 4 is provided between the lower end of the drive transmission frame 32 and the base 1 and the upper end is hingedly connected to the transfer mechanism 2. Thus, the lifting transmission mechanism 3 forms a support between the transfer mechanism 2 and the base 1, and the X-shaped structure formed by the support transmission frame 31 and the drive transmission frame 32 can utilize its own rigidity and the triangular support formed to achieve a good support capability for the transfer mechanism 2.

[0031] The lifting drive 4 of this embodiment includes a lifting drive cylinder installed on the base 1, and the piston rod of the lifting drive cylinder is connected to the lower end of the driving transmission frame 32. Preferably, a synchronous transmission connecting rod 41 is connected between the lower ends of adjacent driving transmission frames 32, and the lower end of one of the driving transmission frames 32 is connected to the lifting drive 4, so that one lifting drive 4 can drive multiple driving transmission frames 32 to move simultaneously, thereby improving the synchronization of lifting transmission, so that each lifting transmission mechanism 3 can effectively generate good supporting capacity at each time point of lifting.

[0032] The lifting drive cylinder of this embodiment directly adopts a double-headed cylinder, which is installed between two adjacent drive transmission frames 32, and the two ends of its piston rod are respectively connected to the lower ends of the two adjacent drive transmission frames 32, and also serve as the synchronous transmission connecting rod 41 between the two adjacent drive transmission frames 32. Of course, at this time, the cylinder barrel of the lifting drive cylinder is fixedly installed on the base 1. The double-headed cylinder is a well-known technology in which the two ends of the piston rod extend out of the cylinder barrel and can move synchronously with the piston in the cylinder barrel, and its structural principle will not be repeated here.

[0033] Preferably, the base 1 is provided with a fixed slide rail 33, on which a transmission slider 34 is slidably mounted, and the lower end of the drive transmission frame 32 is hingedly connected to the transmission slider 34, so that the lifting transmission mechanism 3 is supported at two points on the base 1 and two points on the transfer mechanism 2, and two triangular supports are formed, and the supporting capacity is further enhanced. The driving end of the lifting drive 4 is connected to the transmission slider 34, and the driving stability of the lifting drive 4 is improved through the sliding connection, and it is conducive to reducing the driving force requirement.

[0034] Preferably, a support roller 35 is installed on the high end of the support transmission frame 31, and the support roller 35 is arranged to abut against the bottom of the transfer mechanism 2 to support the rolling contact of the support roller 35, thereby reducing the resistance between the high end of the support transmission frame 31 and the transfer mechanism 2 during the above-mentioned X-shaped structure deformation process, further improving the stability of the driving process, and facilitating further reducing the driving force requirement of the lifting drive 4.

[0035] Preferably, the driving transmission frame 32 is arranged in a vertical direction along the transfer direction, so that no matter how the above-mentioned X-shaped structure changes, the support width of the lifting transmission mechanism 3 in the direction perpendicular to the transfer direction does not change, so the multiple lifting transmission mechanisms 3 can always maintain stable support for multiple points of the transfer mechanism 2.

[0036] When this embodiment is in use, at least two sets are used in combination. When the lifting driver 4 drives the lower end of the driving transmission frame 32 to approach the lower end of the supporting transmission frame 31, the driving transmission frame 32 and the supporting transmission frame 31 both stand up, the transfer mechanism 2 rises, and together lifts up the steel component. The transfer mechanism 2 starts, moves the steel component to the specified position, and then stops. The lifting driver 4 drives the lower end of the driving transmission frame 32 away from the lower end of the supporting transmission frame 31, the driving transmission frame 32 and the supporting transmission frame 31 both lie down, and the transfer mechanism 2 descends, and the steel component thereon falls onto the downstream workbench 9 for subsequent processing. Therefore, this embodiment is suitable for performing circulation transfer between two sets of workbenches 9, and corresponding spaces for installing this embodiment can be set on the two sets of workbenches 9.

[0037] In this embodiment, the steel component is lifted and transferred. The X-shaped structure of the lifting transmission mechanism 3 can provide effective support throughout the whole process, so that the transfer capacity of this embodiment is strong, the transfer process is stable, and it is less affected by the size and weight of the steel component. It can be transferred to the right place at one time, so the turnover is reliable, the safety risk is low, and the efficiency is high.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
