Description

Crane turntable assembly positioner Technical Fields

[0001] This application relates to the field of positioner technology, and in particular to a crane turntable assembly positioner. Background Technology:

[0002] The turntable of a crane is an important component, its function being to enable the crane to rotate and position horizontally. The turntable typically consists of a slewing mechanism fixed plate and a support structure. After the slewing mechanism fixed plate and support structure are assembled on one working platform, the turntable needs to be flipped to another working platform for bottom welding.

[0003] Chinese utility model patent application number 202221850160.1 discloses a clamping and flipping positioning machine, including a fixed component, a support component rotatably connected to the fixed component, and the fixed component and support component rotatably connected via a rotating component. Two sets of clamping arm assemblies for clamping workpieces are symmetrically arranged on the support component. In this application, the fixed component and support component are rotatably connected via the rotating component, causing the workpiece to flip, enabling welding on all surfaces of the workpiece. This reduces the number of times the workpiece is disassembled and clamped, improving work efficiency and welding position accuracy. The flipping reducer in this application uses a worm gear reducer with mechanical self-locking transmission, ensuring the stability of the flipping position and preventing workpiece swaying. In this application, the threads at both ends of the lead screw are opposite in direction; the rotation of the lead screw drives the two sets of clamping arms to move relative to or towards each other, thereby centering and clamping the workpiece, ensuring the positional requirements of multiple welding points at the workstation and providing high stability.

[0004] The existing flipping method generally uses the positioner in the above patent for flipping. Since the crane turntable is roughly triangular in structure, the positioner cannot be lowered after flipping. Workers need to use the steel wire of the gantry crane to hang it under the turntable while the positioner is holding the turntable, and then lift it to another work platform. This is inefficient and there are many uncertainties in the gantry crane lifting, which can easily cause safety accidents. Invention content and utility model content:

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0034] The crane turntable assembly includes a base 1, a rotary drive A2, and a column 3. The base 1 is connected to the column 3 via the horizontal rotary drive A2. A mounting plate 4 is vertically mounted on one side of the column 3 in a sliding manner. The mounting plate 4 is connected to the lifting arm 6 via the rotary drive B5. The lifting arm 6 is equipped with two clamping arms 7 in a sliding manner. The two clamping arms 7 can reciprocate along the axial direction of the lifting arm 6. The clamping arms 7 are equipped with a fixed arm 11 and a clamping member 10 in a fixed manner. The clamping member 10 can press the fixed plate of the rotary mechanism against the end face of the fixed arm 11, which satisfies the stability of clamping during the tilting and transfer process and improves safety. It also facilitates the column 3 to move the turntable to the other side of the working platform through the clamping arms 7, which greatly improves the efficiency of tilting and lifting.

[0035] It should be noted that the mounting plate 4 and the column 3 are slidably connected via linear guide rail A17.

[0036] A first driving mechanism 8 is also provided for driving the mounting plate 4 to slide on the column 3. The first driving mechanism 8 includes a first hinge seat 81 fixedly connected to the mounting plate 4. The first hinge seat 81 is provided with a hydraulic cylinder A82 through a hinge structure. The other end of the hydraulic cylinder A82 is provided with a second hinge seat 83 through a hinge structure. The second hinge seat 83 is fixedly connected to the column 3. The hydraulic cylinder A82 is used to drive the mounting plate 4 to slide up and down on the column 3.

[0037] It should be noted that a second drive mechanism 9 is also provided, which is connected to the lifting arm 6 and the clamping arm 7 to drive the two clamping arms 7 to move closer or further away.

[0038] Specifically, the second drive mechanism 9 includes a positive and negative lead screw 91 that is rotatably connected to the lifting arm 6. The positive lead of the positive and negative lead screw 91 is connected to the left clamping arm 7 by a threaded engagement, and the negative lead of the positive and negative lead screw 91 is connected to the right clamping arm 7 by a threaded engagement. A rotary motor 92 is also provided for driving the positive and negative lead screw 91 to rotate. The rotary motor 92 is fixedly connected to the lifting arm 6.

[0039] It should be noted that the lifting arm 6 and the clamping arm 7 are connected by a linear guide rail B93.

[0040] Specifically, the clamping component 10 is a hydraulic cylinder C, which is connected to the clamping arm 7 in a fixed structure. The output shaft of the hydraulic cylinder C extends to press the rotating mechanism fixing plate against the end face of the fixing arm 11.

[0041] It should be noted that in another embodiment based on the above embodiments, a positioning plate 12 is provided on the inner side of the mounting plate 4 in a fixed structure manner, and the positioning plate 12 has a locking hole; a locking rod 13 is used in conjunction with the locking hole in a plug-in structure manner.

[0044] The working principle and process of this utility model are as follows:

[0045] First, start the hydraulic cylinder A82. The output shaft of the hydraulic cylinder A82 drives the mounting plate 4 to move on the linear guide rail B93 through the first hinge seat 81. The mounting plate 4 drives the lifting arm 6 and the clamping arm 7 to move to the predetermined position. Then, start the rotary motor 92. The rotary motor 92 drives the positive and negative lead screws 91 to rotate on the lifting arm 6. The positive and negative lead screws 91 drive the two clamping arms 7 to move inward through the positive and negative leads respectively until the support structure is clamped. Then, start the hydraulic cylinder C10 to press the rotating mechanism fixing plate against the end face of the fixing arm 11, completing the clamping work before transfer.

[0046] Start hydraulic cylinder A82 to lift mounting plate 4 to the predetermined height, then start rotary drive B to drive lifting arm 6, clamping arm 7 and turntable to rotate 180 degrees. Then start rotary drive A to drive the mechanism on column 3 to rotate until it rotates to the upper part of another action platform. Then hydraulic cylinder A82 drives mounting plate 4 to descend, opening the clamping arm 7 and hydraulic cylinder C10 from restricting the turntable, completing the flipping and transfer work.
