Description

Technical Field

[0001] The invention relates to the technical field of pressure vessel overturning, in particular to a pressure vessel overturning device. Background Art

[0002] A pressure vessel is a closed device that contains gas or liquid and bears a certain pressure. After the vertical pressure vessel is manufactured in the factory, it is often sent to the installation site in a horizontal state for easy transportation. After being transported to the site, the vertical pressure vessel needs to be flipped to a vertical state for installation. For some small vertical containers, after flipping them to a vertical state, they can be directly moved to the place to be installed by a transfer vehicle.

[0003] In order to prevent the vertical container from falling off from the bottom, the current flipping equipment will set a pallet to hold the bottom of the vertical container. However, the bottom of the vertical container is installed with a support frame. Since the support frame is directly in contact with the pallet, after releasing the binding of the vertical container, it is necessary to use a crane to lift the vertical container to the transfer vehicle. The overall operation is relatively cumbersome; although the pallets of some flipping equipment have made specific settings for a certain support frame, so that the support frame of the flipped vertical container falls directly on the transfer vehicle, it cannot adapt to the use of multiple types of support frames. Based on this, a pressure vessel flipping device is proposed. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0034] Example 1

[0035] Different types of pressure vessels have different base support structures. The traditional bottom blocking structure can only meet the requirements of a certain base support structure, which limits the application of the device. In order to solve the above problems, this embodiment provides a pressure vessel flipping device, referring to Figure 1-Figure 10 As shown, it includes a substrate 1 and a turning platform 2 located above the substrate 1. The middle section of the turning platform 2 is concave inward to form an arc-shaped surface, which can better adapt to the surface of pressure vessels of various sizes. A power mechanism 3 for adjusting the angle of the turning platform 2 is arranged between the substrate 1 and the turning platform 2. The turning platform 2 can be driven to deflect through the power mechanism 3 to make it in a horizontal state or a vertical state. A binding mechanism 5 for fixing the pressure vessel thereon is arranged on the turning platform 2, and a bottom-covering mechanism 7 for preventing the pressure vessel from sliding is arranged at the end of the turning platform 2. An adjustment mechanism 6 for allowing the bottom-covering mechanism 7 to be attached to the tail end of the pressure vessel is arranged on the turning platform 2. For some pressure vessels with smaller volumes, when the pressure vessel needs to be turned over, the pressure vessel is first hoisted horizontally on the turning platform 2 by a lifting device, and the pressure vessel is bound to the turning platform by the binding mechanism 5, and then the bottom-covering mechanism 7 is adjusted by the adjustment mechanism 6 to make it abut against the tail end of the pressure vessel, and then the transport vehicle is moved to the tail side of the turning device. Start the power mechanism 3 to drive the turning table 2 to rotate 90° to a vertical state. At this time, the supporting legs of the pressure vessel are located directly above the workbench of the transport vehicle. The binding is untied, and the adjustment mechanism 6 is used to drive the bottom support mechanism 7 to move downward, and the pressure vessel is moved downward together until the supporting legs on it abut against the workbench of the transport vehicle. Then the pressure vessel can be slowly transported to the designated position by the transport vehicle. The overall operation is relatively simple and convenient, and the bottom support mechanism 7 set can meet the use of a variety of base support structures and can better meet the actual use needs.

[0036] The bottom support mechanism 7 mentioned above includes a slot seat 71 that is integrally connected. The slot of the slot seat 71 is cross-shaped. An abutment rod 72 is slidably installed in the slot seat 71. The portion of the abutment rod 72 located in the slot seat 71 is cross-shaped to match it. A receiving slot 75 is provided in the abutment rod 72. An elongated plate 73 is slidably installed in the receiving slot 75. A locking screw 74 for locking the elongated plate 73 is installed on the abutment rod 72. When facing a pressure vessel with a larger tail end size, the elongated plate 73 can be pulled out to increase the support area and ensure stable support of the pressure vessel with a larger tail end size. The abutment rod 72 and the slot seat 71 are correspondingly locked. Specifically, it also includes a folding plate 77 fixed on the abutment rod 72, the folding plate 77 is generally in an inverted L shape, and a plurality of groups of limiting holes 76 are arranged at intervals on the slot seat 71, and a limiting rod 78 used in conjunction with the limiting holes 76 is slidably installed on the folding plate 77, and a circular plate 710 is fixed to the end of the limiting rod 78 away from the slot seat 71, and a tension spring 79 is sleeved on the limiting rod 78, and the tension spring 79 is fixed between the circular plate 710 and the folding plate 77. By pulling the circular plate 710 outward, the limiting rod 78 is driven to move outward and disengage from the original limiting hole 76. After moving the abutment rod 72 to a suitable position as required, the circular plate 710 is released, and the limiting rod 78 is inserted into the limiting hole 76 at the corresponding position under the tension of the tension spring 79. By adjusting the position and number of the abutment rods 72, the use of pressure vessels with various base support structures can be met. Fig.10 For reference, the details are as follows:

[0037] As for the three sets of supporting legs fixed at the rear end of the pressure vessel, the position of the abutment rod 72 can be adjusted as follows: Fig.10 As shown in a; as for the four sets of supporting legs fixed at the tail end of the pressure vessel, the position of the abutment rod 72 can be adjusted as shown Fig.10 As shown in b; with respect to the six sets of supporting legs fixed at the tail end of the pressure vessel, the position and number of the abutment rods 72 can be adjusted as shown Fig.10 As shown in c.

[0038] After the pressure vessel is hung on the turning table 2, the rear end of the pressure vessel is not directly in contact with the abutment rod 72, and there is a certain gap between the two. If there is no close contact, after turning to a vertical state and unbinding, the impact force generated by the falling of the pressure vessel may damage the abutment rod 72 or even the entire device. In order to solve the above problem. An adjustment mechanism 6 is provided, which includes a bearing plate 62 slidably installed in a blind groove at the end of the turning table 2, and a second hydraulic rod 61 installed in the blind groove to drive the bearing plate 62 to move. After the pressure vessel is hung on the turning table 2, the second hydraulic rod 61 is started to drive the bearing plate 62 toward the rear end of the pressure vessel, and the abutment rod 72 moves in the same direction and abuts against the rear end of the pressure vessel, thereby avoiding the generation of a gap and improving the safety of the device.

[0039] The binding mechanism 5 mentioned above includes a shell 51 fixed on one side of the turning table 2, and a plurality of groups of hooks 59 fixed on the other side of the turning table 2. The shell 51 is provided with a plurality of groups of notches 52 at intervals, and a support shaft 53 is rotatably installed in the shell 51. A strap 54 is wound around the position of the support shaft 53 corresponding to the notch 52. The strap 54 passes through the corresponding notch. A hanging rod 510 used in conjunction with the hook 59 is fixed to the end of the strap 54 away from the support shaft 53. A control member for driving the rotation of the support shaft 53 is installed on the shell 51. After the pressure vessel is hung on the turning table 2, the control member is used to drive the support shaft 53 to rotate, thereby realizing the unwinding of each group of straps 54. After that, the staff will pass the hanging rod 510 around the top of the pressure vessel and clamp it at the position of the hook 59, and then use the control member to drive the support shaft 53 to rotate in the opposite direction to tighten the strap 54, thereby binding the pressure vessel to the turning table 2. The overall operation is simple and convenient.

[0040] The binding mechanism 5 also includes a control component, which includes a frame plate 55 fixed to the housing 51, on which a worm 56 and a reduction motor 58 for driving the worm 56 to rotate are rotatably mounted, and a worm wheel 57 mounted on the end of the support shaft 53 is engaged with the worm 56. By controlling the reduction motor 58 to rotate forward and reverse, the worm 56 is driven to rotate, and then the worm wheel 57 is driven to rotate, so that the support shaft 53 can be driven forward and reverse.

[0041] The power mechanism 3 mentioned above includes a frame 31 fixed on the base plate 1, and a connection seat 33 fixed on the flip table 2. A rotating shaft 32 fixed to the connection seat 33 is rotatably mounted on the frame 31. Deflection rods 34 are rotatably mounted on both ends of the rotating shaft 32. A first hydraulic rod 35 is rotatably mounted between the deflection rod 34 and the base plate 1. When the pressure vessel needs to be flipped to a vertical state, the first hydraulic rod 35 is started to drive the deflection rod 34 to rotate, and then drive the rotating shaft 32 to rotate. Through the cooperation of the connection seat 33, the flip table 2 can be driven to deflect.

[0042] Example 2

[0043] refer to Figure 1 and Figure 4 , a plurality of buffer mechanisms 4 are also provided on the base plate 1 to prevent the flip table 2 from causing a large impact force when rotating from a vertical state to a horizontal state. Specifically, the buffer mechanism 4 includes two groups of cylinders 41 fixed on the base plate 1, and a telescopic rod 42 is slidably mounted on the cylinder 41. A buffer rod 43 and a moving plate 44 are fixed to the top and bottom ends of the telescopic rod 42, respectively, and a spring 46 is fixed between the moving plate 44 and the inner wall of the cylinder 41. When the flip table 2 rotates to a horizontal state, it first contacts the buffer rod 43 and is acted upon by the elastic force of the spring 46, which has a certain shock-absorbing and buffering effect, preventing the flip table 2 from rotating too fast and colliding with the buffer rod 43 to cause the entire device to vibrate, thereby reducing damage to the device.

[0044] Furthermore, the buffer mechanism 4 also includes buffer oil 47 filled in the cylinder 41, and a plurality of overflow holes 45 provided on the movable plate 44. When the flip table 2 presses down the buffer rod 43, the downward movement speed of the buffer rod 43 can be slowed down due to the resistance of the buffer oil 47, thereby further improving the buffer effect and ensuring the stability of the device.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
