Description

Technical Field

[0001] The present disclosure relates to the technical field of transport boxes, and in particular to a tank box rotating ring transfer device. Background Art

[0002] In the manufacturing process of tank storage containers, when the tank body is installed with the end frame and the top and bottom side beams, the appearance changes from a cylindrical shape to a frame structure. When welding other parts of the tank body, the tank box needs to be rotated. How to achieve the rotation of the frame structure tank box has become a difficult problem in the industry. The current method is to install a process rotating ring at each end. After the welding process is completed, it is disassembled and returned to the previous process for recycling.

[0003] However, during the current use, each installation and loading and unloading of the process rotating ring is carried out by a cantilever crane at a single point, and personnel are required to climb to work. That is, after manually tying the rope to the rotating ring, the cantilever crane is used to lift it to the predetermined position, and after manually aligning the placement position, the rotating ring is removed. This operation method is inefficient and has poor precision, and there are safety hazards even if the height is kept low. Summary of the invention

[0004] One purpose of the present disclosure is to provide a tank container rotating ring transfer device to solve the technical problems of low efficiency, poor precision and potential safety hazards in the prior art of rotating ring loading and unloading operations.

[0005] In order to solve the above technical problems, the present disclosure adopts the following technical solutions:

[0006] According to one aspect of the present disclosure, the present disclosure provides a tank container rotating ring transfer device, which is used to transport the rotating ring connected and fixed at both ends of the tank container, and includes a frame, a walking mechanism, a lifting frame and a grabbing mechanism. The top of the frame is provided with a horizontal track in the horizontal direction; the walking mechanism is movably arranged on the horizontal track; the lifting frame is vertically arranged at the bottom of the walking mechanism, and is rotatably connected to the walking mechanism in the horizontal direction, and a lifting track is arranged on one side of the lifting frame in the vertical direction; the grabbing mechanism includes a mechanism body, a tray and a limiting component; the mechanism body is slidably connected to the lifting track so that the grabbing mechanism can be lifted and lowered along the lifting frame; the tray is arranged at the side of the bottom of the mechanism body away from the lifting frame, and the tray is in contact with the bottom surface of the top of the rotating ring to support the rotating ring; the limiting component cooperates with the tray to limit the rotating ring on the tray.

[0007] It can be seen from the above technical solutions that the present disclosure has at least the following advantages and positive effects:

[0008] In the present disclosure, the entire rotating ring is lifted up by the tray of the grabbing mechanism, and then after being raised along the lifting frame, the lifting frame rotates to adjust the direction of the rotating ring, and then the walking mechanism moves horizontally along the frame body, so that the two sides of the rotating ring can be aligned with the top hole of the top corner piece of the tank box, thereby realizing automatic insertion and extraction of the two sides of the rotating ring from the top hole, eliminating the risk of personnel climbing up. At the same time, the lifting direction and horizontal walking direction of the transfer mechanism disclosed in the present disclosure are both carried out by moving along the track, so compared with the prior art, there will be no problem of shaking of the rope and the rotating ring during rope fixing, which ensures the accuracy of the action, so that the two sides of the rotating ring can be aligned with the top hole of the top corner piece, solving the technical problems of low efficiency, poor accuracy and potential safety hazards in the prior art of rotating ring loading and unloading.

[0016] Although the present disclosure can be easily embodied in different forms of embodiments, only some of the specific embodiments are shown in the drawings and will be described in detail in this specification. It should be understood that this description should be regarded as an exemplary illustration of the principles of the present disclosure and is not intended to limit the present disclosure to that described herein.

[0017] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present disclosure, rather than implying that each embodiment of the present disclosure must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0018] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the present disclosure are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, the indications of these directions also change accordingly.

[0019] In conjunction with the drawings of this specification, some embodiments of the present disclosure are further described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] See also Figure 1 and Figure 2 The present disclosure provides a tank container rotating ring transfer device, which is used to transfer the rotating rings 2 vertically arranged at both ends of the tank container. The tank container rotating ring transfer device includes a frame 100, a traveling mechanism 200, a lifting frame 300 and a grabbing mechanism 400. A horizontal track 111 is provided at the top of the frame 100 along the horizontal direction, and the traveling mechanism 200 is movably arranged on the horizontal track 111. The lifting frame 300 is vertically arranged at the bottom of the traveling mechanism 200, and is rotatably connected to the traveling mechanism 200 along the horizontal direction. A lifting track 310 is provided on one side of the lifting frame 300 along the vertical direction. The grabbing mechanism 400 is used to grab the rotating rings 2 at both ends of the tank container, and is slidably connected to the lifting track 310. After grabbing the rotating ring 2, the grabbing mechanism 400 can slide up and down along the lifting track 310 to remove the rotating ring 2. Then the traveling mechanism 200 can move along the horizontal track 111 to move the rotating ring 2 to a designated location.

[0021] The frame 100 includes a plurality of columns 120 and a top frame 110. The columns 120 are vertically arranged on the ground or mounted on a mounting platform. The top frame 110 is fastened and mounted on the top of the columns 120 by bolts or other fasteners. In other embodiments, it can also be welded to the top of the columns 120. The top frame 110 is surrounded by two oppositely arranged longitudinal beams 112 and two oppositely arranged transverse beams 113, and also includes the above-mentioned horizontal rails 111 arranged on the inner sides of the two longitudinal beams 112 along the extending direction of the longitudinal beams 112.

[0022] In some embodiments of the present disclosure, a walking platform 114 is further provided on the periphery of the top frame 110, and a guardrail 115 is provided on the periphery of the walking platform 114. The guardrail 115 is provided with an opening on one side, and a ladder 116 is provided at the opening to communicate with the walking platform 114. Relevant maintenance personnel can climb onto the walking platform 114 via the ladder 116, and perform maintenance operations on the top of the lifting frame 300 and the walking mechanism 200 on the walking platform 114.

[0023] In some embodiments of the present disclosure, the traveling mechanism 200 is a traveling crane, and gear wheels 210 are provided on both sides thereof, so the above-mentioned horizontal track 111 corresponds to a rack track meshed with the gear wheels 210. The meshed gear rack can play a certain fixed limiting role, which can prevent slippage caused by external factors such as gravity and wind in a static state, and can also improve the accuracy of controlling the displacement of the traveling crane.

[0024] Please refer to Figure 3 At the same time, a slewing mechanism 220 is also provided at the bottom of the above-mentioned traveling crane. The slewing mechanism 220 includes a slewing gear and a slewing driver. The slewing driver is drivingly connected to the slewing gear to drive the slewing gear to rotate. The slewing gear is drivingly connected to the top of the lifting frame 300, and the slewing gear rotates to drive the lifting frame 300 to rotate. The lifting frame 300 is fixed to the bottom of the traveling crane through the slewing gear connection, and moves longitudinally along the horizontal track 111 with the traveling crane. At the same time, the distance between the bottom end of the lifting frame 300 and the bottom surface or the mounting platform is greater than the height of the tank container, so as to ensure that the lifting frame 300 and the grabbing mechanism 400 can pass over the tank container.

[0025] Please refer to Figure 4 The grabbing mechanism 400 includes a mechanism body 410, a tray 420, and a limiting component 430. The mechanism body 410 is slidably connected to the lifting track 310 so that the grabbing mechanism 400 can be lifted and lowered along the lifting frame 300. The tray 420 is disposed at the bottom of the mechanism body 410, away from the lifting frame 300. The tray 420 is in contact with the top bottom surface of the rotating ring 2 to support the rotating ring 2. The limiting component 430 cooperates with the tray 420 to limit the rotating ring 2 on the tray 420.

[0026] Please refer to Figure 5 and Figure 6, the tray 420 includes a support member 421, a supporting beam 422 and a supporting plate 423. The support member 421 extends from the main body 410 of the mechanism, and the supporting beam 422 is arranged at the end of the support member 421, and is used to support the top crossbeam of the rotating ring 2. The supporting plate 423 is arranged on the top surface of the support member 421, and is used to hold up the circular ring of the rotating ring 2, so its top surface can be a curved surface that fits the circular ring of the rotating ring 2. In this embodiment, the supporting plate 423 is located between the supporting beam 422 and the main body 410 of the mechanism, so as to ensure that the side of the rotating ring 2 provided with the connecting hook is away from the main body 410 and is arranged toward the outside, so as to facilitate the grabbing and loading and unloading of the rotating ring 2. Since the bottom surface of the top of the circular ring of the rotating ring 2 is slightly higher than the bottom surface of the top crossbeam, the supporting plate 423 protrudes slightly from the top surface of the supporting beam 422, forming a stepped structure, and also plays a certain limiting role to prevent the rotating ring 2 from axial movement.

[0027] The limiting component 430 includes a pressure ring assembly 431 and a pressure beam assembly 432. The pressure ring assembly 431 is arranged above the supporting plate 423 and faces the supporting plate 423, and is arranged in cooperation with the supporting plate 423 to clamp the circular ring of the rotating ring 2 together with the supporting plate 423. The pressure beam assembly 432 is arranged above the supporting beam 422 and faces the supporting beam 422, and is arranged in cooperation with the supporting beam 422 to clamp the top cross beam of the rotating ring 2 together with the supporting beam 422. The cooperation between the pressure ring assembly 431 and the supporting plate 423 and the pressure beam assembly 432 and the supporting beam 422 can play a role in fixing the rotating ring 2, preventing the rotating ring 2 from falling during the movement of the grabbing mechanism 400, resulting in danger, and also ensuring that the tank container rotating ring transfer device can lift the rotating ring 2 to a higher height relative to the single-point cantilever crane, greatly improving the passability of the rotating ring 2 during the transfer process.

[0028] In some embodiments of the present disclosure, the above-mentioned pressure ring assembly 431 includes a pressure ring cylinder and a pressure ring member that abuts against the circular ring, and the pressure beam assembly 432 includes a pressure beam cylinder and a pressure beam member that abuts against the top cross beam. They are all components driven by cylinders to ensure their reliability and simplify their structure.

[0029] In some embodiments of the present disclosure, please refer to Figure 7The grabbing mechanism 400 also includes a lifting driver 440, an output shaft 450, a climbing gear 460 and a transmission gear 470. The lifting driver 440 is arranged at the middle position of the top of the mechanism body 410, and two output shafts 450 are extended to both sides. The climbing gear 460 is arranged on the two output shafts 450 and is connected to the transmission gear 470. A lead screw 330 is correspondingly arranged along the vertical direction on the lifting frame 300, and the nut 331 of the lead screw 330 is connected to the transmission gear 470. The lifting driver 440 drives the climbing gear 460 through the output shaft 450, and the climbing gear 460 is vertically meshed with the transmission gear 470, so the lead screw 330 and the nut 331 are driven to rotate through the transmission gear 470, so that the grabbing mechanism 400 is lifted and lowered along the lead screw 330.

[0030] In some embodiments of the present disclosure, a plurality of sliders 411 are provided on the side of the mechanism body 410 facing the lifting frame 300, and a limiter 412 is provided on the top of each slider 411. A limiter groove cooperating with the limiter 412 is correspondingly provided on the lifting rail 310 to ensure that the grasping mechanism 400 can be limited to any height of the lifting frame 300 in a stationary state.

[0031] During use, the tank container is placed on the ground or on the mounting platform below the frame 100, with one end thereof facing the grabbing mechanism 400. The traveling overhead crane moves along the traveling track and approaches the tank container. The lifting frame 300 rotates to make the grabbing mechanism 400 face the rotating ring 2. The grabbing mechanism 400 descends to the bottom along the lifting frame 300 and grabs the rotating ring 2. After the rotating ring 2 is inserted into the grabbing mechanism 400, the pressing ring assembly 431 and the pressing beam assembly 432 of the grabbing mechanism 400 press and hold the rotating ring 2. Then the grabbing mechanism 400 rises along the lifting frame 300, and the rotating ring 2 is taken out. It can then be moved to the specified position by the overhead crane.

[0032] In the present disclosure, the entire rotating ring 2 is lifted up by the tray 420 of the grabbing mechanism 400, and then after being lifted up along the lifting frame 300, the lifting frame 300 rotates to adjust the direction of the rotating ring 2, and then the walking mechanism 200 moves horizontally along the frame body 100, so that the two sides of the rotating ring 2 can be aligned with the top hole of the top corner piece of the tank box, thereby realizing automatic insertion and extraction of the two sides of the rotating ring 2 from the top hole, eliminating the risk of personnel climbing up. At the same time, the lifting direction and horizontal walking direction of the transfer mechanism disclosed in the present disclosure are both carried out by moving along the track, so compared with the prior art, there will be no problem of shaking of the rope and the rotating ring during rope fixing, which ensures the accuracy of the action, so that the two sides of the rotating ring can be aligned with the top hole of the top corner piece, solving the technical problems of low efficiency, poor accuracy and potential safety hazards in the loading and unloading operation of the rotating ring 2 in the prior art.

[0033] Although the present disclosure has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present disclosure can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
