[0024] The turntable is an important component structure of the crane, which plays the role of connecting the frame and the boom. The turntable is installed on the slewing bearing and can rotate around the base. The boom, tower or A-frame, various winches and slewing mechanisms and other components can be installed on the turntable. The turntable not only carries the weight of the various components above the crane's unloading and walking system and the weight of the hoisting weight, but also carries the bending moment generated by the hoisting weight and counterweight. Therefore, the turntable has a large volume and weight.

[0025] During the processing of the turntable, it is necessary to process the flange holes on the bottom surface, as well as the boom mounting holes and the boom cylinder mounting holes on the top surface. The turntable needs to be flipped up and down during the processing. Due to the large size and weight of the turntable, it is difficult to flip it manually. If tools such as hooks are used to flip it, there is a risk of it falling. The fall of the turntable will damage the ground and the turntable, and it is very easy to cause safety accidents. The safety and reliability are poor.

[0026] like Figure 1 As shown, the crane turntable flipping device proposed by the present invention is used to fix and flip the turntable 30, wherein the turntable 30 includes a body 31 and flanges 32 located on the left and right sides of the lower part of the body 31, and the flanges 32 are used to connect the turntable 30 with other components. The entire turntable flipping device includes a body 10, and a flipping mechanism 20 is installed on the body 10. The flipping mechanism 20 is used to carry the turntable 30, and is combined with Figure 2 The flipping mechanism 20 includes two clamping arms 201, and the two clamping arms 201 are opposite to each other in the left-right direction. The two clamping arms 201 can fix the main body 31 in the left-right direction, and can fix the flange 32 in the left-right direction and the up-down direction. The two clamping arms 201 are configured to be able to approach or move away from each other in the left-right direction. When the two clamping arms 201 approach each other, the turntable 30 can be clamped and fixed. When the two clamping arms 201 move away from each other, the turntable 30 can be released. The flipping mechanism 20 is configured to be able to rotate relative to the body 10 so that the turntable 30 can be flipped up and down.

[0027] The flipping mechanism 20 is configured to be rotatable relative to the body 10. By changing the angle of the flipping mechanism 20, the angle of the turntable 30 can be changed, so that the upper end surface and the lower end surface of the turntable 30 can be changed, and then the upper and lower ends of the main body 31 can be processed in cooperation with other processing equipment; the two clamping arms 201 can clamp and fix the turntable 30 in the left and right directions and the up and down directions, which can ensure the stability of the turntable 30 during the flipping process, and there is no need to invest a lot of manpower to flip the turntable 30, thereby eliminating the risk of the turntable 30 falling and improving safety; the two clamping arms 201 are configured to be able to move closer to or farther away from each other in the left and right directions, and the movement stroke of the two clamping arms 201 can be adjusted according to the different sizes of the turntable 30, thereby achieving fixation of turntables 30 of different sizes, and has good applicability.

[0028] As an optional embodiment, the two clamping arms 201 extend in the front-to-back direction, and the rear ends of the two clamping arms 201 are connected to the body 10 and are symmetrical in the left-right direction. Figure 3 As shown, the clamping arm 201 includes a side fixing member 21, a bottom supporting member 22 and a first pressing member 23. The side fixing member 21 is used to contact the side surface of the main body 31. The side fixing members 21 of the two clamping arms 201 cooperate to clamp and fix the left and right sides of the main body 31. The bottom supporting member 22 is arranged at a lower position of the side fixing member 21, and a fixing space for accommodating the flange 32 is reserved between the bottom supporting member 22 and the side fixing member 21. The bottom supporting member 22 is used to contact the lower end of the flange 32 to support the flange 32. The first pressing member 23 is connected to the lower end of the side fixing member 21, and its position corresponds to the bottom supporting member 22. The corresponding position means that the position of the first pressing member 23 enables it to cooperate with the bottom supporting member 22 to fix the flange 32 together. The first pressing member 23 is configured to be able to move relative to the bottom supporting member 22 in the up and down direction. The first pressing member 23 cooperates with the bottom supporting member 22 to clamp and fix the flange 32 in the up and down direction.

[0029] In one example of this embodiment, the rear end of the side fixing member 21 is used to connect with the body 10, such as Figure 3 As shown, a connecting end piece 211 is provided at the rear end of the side fixing piece 21 , and the side fixing piece 21 can be connected to the machine body 10 through the connecting end piece 211 .

[0030] In an optional solution, the connecting end piece 211 and the side fixing piece 21 are integrally formed, for example, they can be directly formed into one piece by casting or other processes. In another optional solution, the connecting end piece 211 and the side fixing piece 21 are formed separately, and the two are fixedly connected, for example, they can be connected to form an inseparable whole by welding or other methods, or the two are detachably connected, for example, they are connected by screwing.

[0031] In an example of this embodiment, a detection member is arranged on the bottom support member 22, and the detection member can detect the pressure exerted on the bottom support member 22 by the turntable 30 in the up and down directions. More specifically, the detection member can detect the force applied to the bottom support member 22 by the weight of the turntable 30, so as to ensure that the pressure exerted by the first pressure member 23 on the flange 32 is not too large to damage the flange 32, thereby avoiding the problem of wear and deformation of the turntable 30 due to excessive clamping during the fixing process.

[0032] Optionally, the detection element adopts a weighing sensor or a pressure sensor.

[0033] In one example of this embodiment, when the detection element adopts a weighing sensor, refer to Figure 3The bottom support member 22 includes a first support beam 221, a second support beam 222 and an adjusting member. The first support beam 221 is connected to the upper end of the second support beam 222. The upper end of the first support beam 221 is used to contact the flange 32 and cooperate with the first pressure member 23 to fix the flange 32 in the up and down directions. The detection member is arranged between the first support beam 221 and the second support beam 222 to weigh the change of the force acting on the second support beam 222 by the first support beam 221. The adjusting member is used to cooperate with the detection member, and the adjusting member can adjust the relative position of the first support beam 221 and the second support beam 222.

[0034] Optionally, the adjusting member includes a mounting plate 223 and an adjusting cam 224, the mounting plate 223 is connected to the left and right sides of the second support beam 222, and extends upward to the left and right sides of the first support beam 221, the adjusting cam 224 is mounted on the mounting plate 223, and the position of the adjusting cam 224 is located on the left and right sides of the first support beam 221, and the position and angle of the adjusting cam 224 are adjusted to apply a force to the first support beam 221, so that the first support beam 221 and the second support beam 222 are clamped.

[0035] Since the weighing sensor has a preset up and down stroke during operation, changes in the stroke will cause changes in the gap between the first support beam 221 and the second support beam 222. The adjustment member can be adjusted to avoid a gap between the first support beam 221 and the second support beam 222, thereby avoiding the problem of shaking or swinging of the first support beam 221 when fixing the flange 32, which is beneficial to ensuring the flipping efficiency of the turntable 30.

[0036] In an alternative embodiment, the adjustment cam 224 is implemented as a cam bearing follower.

[0037] In an example of this embodiment, the first pressing member 23 is connected to the lower end of the side fixing member 21 through a cylinder or a hydraulic vertical cylinder, and the first pressing member 23 is connected to the output rod of the cylinder or the hydraulic vertical cylinder.

[0038] In one example of this embodiment, the number of the first pressing member 23 is configured to be at least one, and further, as Figure 3 As shown, the number of the first pressure pieces 23 is set to three, and they are spaced apart in the front-to-back direction, which can be suitable for fixing turntables 30 of different sizes. The three first pressure pieces 23 are configured to be able to move synchronously to cooperate with the bottom support piece 22 to perform high-quality fixation of the flange 32 in the up and down directions, so that the turntable 30 can be relatively still with the clamping arm 201 during the up and down flipping process, avoiding the turntable 30 from shaking during the flipping process and causing wear and collision, and preventing the turntable 30 from falling off the clamping arm 201.

[0039] In this embodiment 1 example, Figure 3As shown, a protective member 24 is provided on the side of the side fixing member 21 close to the turntable 30. The protective member 24 is used to directly contact the side of the body 31. The protective member 24 can protect the end surface of the turntable 30 to avoid damage to the end surface of the turntable 30 during the clamping and fixing process.

[0040] Optionally, the protective member 24 may be a rubber pad, a silicone pad, a resin pad, etc., which can not only play a protective role, but also increase the friction coefficient between the side fixing member 21 and the body 31, which is beneficial to improving the fixing effect.

[0041] In one example of this embodiment, the protective member 24 is provided at one end of the bottom support member 23 close to the flange 32. Those skilled in the art can adjust the size, shape and other parameters of the protective member 24 according to actual needs and the installation position.

[0042] In one example of this embodiment, the end of the first pressing member 23 that contacts the flange 32 is provided with the above-mentioned protective member 24. Those skilled in the art can adjust the size, shape and other parameters of the protective member 24 according to actual needs and the setting position.

[0043] As an optional embodiment, Figure 3 As shown, a second pressing piece 25 is provided at the front end of the side fixing piece 21. The second pressing piece 25 extends in the left-right direction. The second pressing piece 25 is configured to be able to move in the left-right direction relative to the side fixing piece 21 to contact or move away from the side of the main body 31. The second pressing pieces 25 of the two clamping arms 201 cooperate to clamp and fix the main body 31 in the left-right direction.

[0044] Since the turntable 30 has an irregular shape, it is usually difficult to fix it, and it is easy to slip during the fixing and clamping process. The second pressure piece 25 can play a role of supplementary fixing. It is only necessary to find a fixing point suitable for the second pressure piece 25 to contact on the side of the main body 31. The second pressure piece 25 is arranged on the side fixing piece 21 and can move synchronously with the side fixing piece 21 relative to the body 10, which will not increase the time required for clamping and fixing, and is beneficial to improving the stability of the turntable 30 in the left and right directions.

[0045] Optionally, the second pressing member 25 is connected to the front end of the side fixing member 21 through an air cylinder or a hydraulic horizontal cylinder, and the second pressing member 25 is connected to an output rod of the air cylinder or the hydraulic horizontal cylinder.

[0046] Optionally, the end of the second pressing member 25 that contacts the body 31 is provided with the above-mentioned protective member 24. Those skilled in the art can adjust the size, shape and other parameters of the protective member 24 according to actual needs and setting position.

[0047] As an optional embodiment, Figure 2As shown, the flip mechanism 20 further includes a driving unit 26 , and the two clamping arms 201 are mounted on the machine body 10 via the driving unit 26 .

[0049] In one alternative, if Figure 2 As shown, the driving part 26 includes a support chain 261 and a driving wheel connected to the support chain 261. The driving wheel can rotate around its own axis to cooperate with the drag chain 261 to drive the two clamping arms 201 to move synchronously along the left and right directions. The two clamping arms 201 are configured to move synchronously, so that the turntable 30 can be located in a centered position when fixed, without causing the position to be skewed and affecting the fixing effect.

[0050] In another optional solution, the driving part 26 includes a rack and a gear connected to the rack. The gear is driven by a driving member to rotate around its own axis. The gear and the rack are meshed and driven to drive the two clamping arms 201 to move synchronously in the left and right directions.

[0051] As an optional embodiment, Figure 2 As shown, a mounting frame 11 is provided on the body 10, and the flip mechanism 20 is connected to the body 10 through the mounting frame 11.

The mounting frame 11 is installed at the front end of the body 10 through a rotating shaft, and the mounting frame 11 can rotate relative to the body 10 around the axial direction of the rotating shaft, thereby driving the flip mechanism 20 to rotate relative to the body 10.

[0052] In an optional solution, the mounting frame 11 is configured to be able to rotate 180° around the axial direction of the rotating shaft, and to realize forward and reverse rotation. Taking the upper end surface of the turntable 30 fixed facing upward as an example, when the mounting frame 11 is rotated 180° in the forward direction, the turntable 30 flips over to have the lower end surface facing upward. At this time, when the mounting frame 11 is rotated 180° in the reverse direction again, the turntable 30 flips over to have the upper end surface facing upward (i.e., reset).

[0053] In another optional solution, the mounting frame 11 is configured to be able to rotate 360° around the axial direction of the rotating shaft and can only rotate in one direction. Taking the upper end surface of the turntable 30 fixed facing upward as an example, when the mounting frame 11 rotates 180° in the forward direction, the turntable 30 flips over to face the lower end surface upward. At this time, when the mounting frame 11 continues to rotate 180° in the same direction, the turntable 30 flips over to face the upper end surface upward (i.e., reset).

[0054] As an optional embodiment, in combination with Figure 1 and Figure 3A lifting plate 12 is installed on the body 10, and the flip mechanism 20 and the mounting frame 11 are installed on the lifting plate 12 and installed on the body 10 through the lifting plate 12. The lifting plate 12 is configured to be able to move in the up and down directions relative to the body 10 to drive the flip mechanism 20 and the mounting frame 11 to rise and fall, and the height and position of the two clamping arms 201 can be adjusted according to the different sizes of the turntable 30 and the storage position of the turntable 30, thereby meeting different fixing and flipping requirements.

[0055] In an optional solution, a slide rail 13 is provided at the front end of the machine body 10, and the slide rail 13 extends in the up-down direction. The lifting plate 12 is slidably connected to the slide rail 13 so as to move in the up-down direction relative to the slide rail 13. In another optional solution, the lifting plate 12 is connected to the slide rail 13 through a gear rack transmission assembly, and a driving member drives the gear to rotate around its own axis, and the meshing transmission of the gear and the rack can drive the lifting plate 12 to move in the up-down direction along the slide rail 13.

[0056] As an optional embodiment, in combination with Figure 1 and Figure 4 The machine body 10 is arranged on a guide rail 101 so that it can move along the guide rail 101 to grab, fix, and flip the turntable 30 from its storage place, and can transport the turntable 30 along the guide rail 101 to the processing equipment for processing. A track matching piece 14 is provided at the lower part of the machine body 10, and the track matching piece 14 is used to cooperate with the guide rail 101 so that the machine body 10 can move along the guide rail 101.

[0057] Optionally, a busbar connected to an external power source is provided on the guide rail 101 , and the rail fitting 14 uses a brush that matches the busbar, and the brush is slidably connected to the busbar, so that the body 10 can move along the guide rail 101 .

[0058] In one example of this embodiment, Figure 4 As shown, a control member 15 is provided at the lower portion of the machine body 10 , and the control member 15 can cooperate with the guide track 101 to monitor and determine the position of the machine body 10 on the guide track 101 in real time.

[0059] Optionally, the control component 15 uses a barcode scanner, and a position barcode representing the position is provided on the guide track 101. When the body 10 moves along the guide track 101 until the barcode scanner can scan the position barcode, the position of the body 10 can be determined. The position barcode can be set according to the location of the processing equipment so that the body 10 can automatically move to the processing equipment to process the turntable 30. In one example of this embodiment, Figure 4As shown, the body 10 includes a base 16, a support base 17 and a swivel base 18. The support base 17 is installed on the base 16 through the swivel base 18. The swivel base 18 is configured to be able to rotate relative to the base 16 to drive the support base 17 to rotate relative to the base 16. The flip mechanism 20, the mounting frame 11 and the lifting plate 12 are all installed on the support base 17. Through the rotation of the support base 17 relative to the base 16, the angle of the flip mechanism 20 relative to the base 16 can be changed, so that the flip mechanism 20 can be conveniently adjusted according to the position of the turntable 30 and the position of the processing equipment, so as to facilitate the placement and removal of the turntable 30.

[0060] Optionally, the support seat 17 is configured to be rotatable 360° relative to the base 16 .

[0061] As an optional implementation method, a main control screen is also provided on the body 10 to display data in real time, such as the height and angle of the two clamping arms 201, the detection data of the detection parts, etc., which is conducive to realizing intelligent control and is more intuitive. Instructions can also be issued through the central control screen to adjust the height and angle of the two clamping arms 201, the prompt signal trigger value of the detection parts, etc.

Based on the need to perform a flipping operation on the turntable 30, the two clamping arms 201 rotate 180° relative to the machine body 10 to flip the turntable 30 upside down.

[0063] As an optional embodiment, the above step S1 further includes: S1.1. When the two clamping arms 201 approach each other in the left-right direction, until the two side fixing members 21 contact the left and right sides of the body 31, the flanges 32 on both sides of the body 31 are located at the upper end of the bottom support member 22, and the two clamping arms 201 stop moving.

[0064] As an optional embodiment, the above step S1 further includes: S1.2, the first pressing member 23 moves downward until it contacts the upper end of the flange 32, until the detection member sends a prompt signal, the first pressing member 23 receives the prompt signal and stops moving; in this step, the pressure (or weight) on the bottom support member 22 is measured by the detection member, and when the detection value reaches a preset value, a prompt signal can be sent. The detection member sends a prompt signal to control the movement stroke of the first pressing member 23, which can ensure the fixing effect and ensure that the first pressing member 23 does not over-clamp and damage the flange 32; As an optional embodiment, the above step S1 further includes: S1.3, the two second pressing members 25 move closer to each other in the left-right direction, move to contact the left and right sides of the body 31, and clamp the body 31 in the left-right direction; in this step, the second pressing members 25 cooperate with the side fixing members 21 to fix the turntable 30 at multiple points in the left-right direction; As an optional embodiment, the above step S1 further includes: S1.01. Based on the height of the position where the turntable 30 is placed, the lifting plate 12 moves in the up-down direction relative to the machine body 10, and the height of the flip mechanism 20 is adjusted so that the positions of the two clamping arms 201 correspond to the position of the turntable 30. In this step, the place where the turntable 30 is placed can be a place where the processing equipment has been completed. For example, after the upper end surface of the turntable 30 is processed, the turntable 30 needs to be flipped by the flip mechanism 20 so that the lower end surface can be processed by another processing equipment. At this time, the aforementioned processing equipment that has been processed is the processing equipment used to process the upper end surface of the turntable 30, and the place where the turntable 30 is placed can also be a storage place before processing.

[0065] As an optional embodiment, the above step S1 further includes: S1.02, based on the position of the turntable 30, the support seat 17 rotates relative to the base 16 so that the angle of the flip mechanism 20 corresponds to the position of the turntable 30. In this step, the turntable 30 can be placed at a processing device that has been processed or at a storage location before processing.

[0066] As an optional embodiment, the crane turntable flip control method proposed by the present invention includes the following steps: S1.01. Based on the height of the position where the turntable 30 is placed, the lifting plate 12 moves in the up-down direction relative to the machine body 10 to adjust the height of the flip mechanism 20 so that the positions of the two clamping arms 201 correspond to the position of the turntable 30; S1.02, based on the position of the turntable 30, the support seat 17 rotates relative to the base 16 so that the angle of the flip mechanism 20 corresponds to the position of the turntable 30; S1, control the two clamping arms 201 to move closer to each other along the left and right directions until the two side fixing members 21 contact the left and right sides of the body 31, the flanges 32 on both sides of the body 31 are located at the upper end of the bottom support member 22, and the two clamping arms 201 stop moving; The first pressing member 23 moves downward until it contacts the upper end of the flange 32, until the detection member sends a prompt signal, and the first pressing member 23 receives the prompt signal and stops moving; The two second pressing members 25 move toward each other in the left-right direction, move to contact the left and right sides of the body 31, and clamp the body 31 in the left-right direction; S2. Based on the need to perform a flipping operation on the turntable 30, the two clamping arms 201 rotate 180° relative to the machine body 10 to flip the turntable 30 upside down.

[0067] Based on the above-mentioned crane turntable turning device, the present invention also proposes a crane turntable processing system, such as Figure 6 As shown, including: A guide rail 101, on which the body 10 is movably disposed and can move along the extension direction of the guide rail 101; The top surface processing device 102 is disposed on one side of the guide rail 101 and is used to process the upper end surface of the turntable 30; The bottom surface processing device 103 is disposed on one side of the guide rail 101 and is used to process the lower end surface of the turntable 30 . The bottom surface processing device 103 and the top surface processing device 102 are located on the same side of the guide rail 101 , or on both sides of the guide rail 101 .

[0068] As an optional embodiment, the top surface processing device 102 is used to perform a drilling operation on the upper end surface of the turntable 30 to process the boom mounting hole and the boom cylinder mounting hole on the upper end surface of the turntable 30 .

[0069] As an optional embodiment, the bottom surface processing device 103 is used to perform a drilling operation on the lower end surface of the turntable 30 to process a flange hole on the lower end surface of the turntable 30 .

[0070] As an optional embodiment, Figure 6 As shown, the guide rail 101 extends in the front-to-back direction, and the top surface processing device 102 and the bottom surface processing device 103 are located on both sides of the guide rail 101 in the left-right direction. The machine body 10 moves to the top surface processing device 102 relative to the guide rail 101 to transport the upper end surface of the turntable 30 upward to the top surface processing device 102 for processing. After the processing is completed, the turntable 30 is turned upside down, and at the same time, the support seat 17 is rotated to rotate the flipping mechanism 20 to the side away from the top surface processing device 102, and then the lower end surface of the turntable 30 is transported upward to the bottom surface processing device 103 for processing.

[0071] It is understandable that the above processing sequence, as well as the sequence of flipping and rotating can be adjusted according to actual needs and does not have to be performed in this order.

[0072] Optionally, the top surface processing device 102 and the bottom surface processing device 103 are symmetrically arranged on both sides of the guide rail 101. After the upper end surface processing is completed, the support seat 17 rotates 90°, the flipping mechanism 20 flips the turntable 30, and the support seat 17 rotates another 90° to send the turntable 30 to the bottom surface processing device 103.

[0073] As an optional embodiment, the guide rail 101 extends in the front-to-back direction, the top surface processing device 102 and the bottom surface processing device 103 are located on the same side of the guide rail 101 in the left-right direction, and the body 10 moves relative to the guide rail 101 to the top surface processing device 102 to transport the upper end surface of the turntable 30 upward to the top surface processing device 102 for processing. After the processing is completed, the support seat 17 rotates an angle, and the flipping mechanism 20 flips the turntable 30 upside down, and then moves along the guide rail 101 to the bottom surface processing device 103 for processing.

[0074] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
