Description

Technical Field

[0001] This invention relates to erection equipment, belonging to the field of engineering machinery equipment, and particularly to a large equipment tilting and erection device. Background Technology

[0002] For large or heavy-duty test platforms and engineering machinery, erecting large equipment in outdoor or certain restricted conditions and special application scenarios is a challenging problem. For example, in outdoor test sites, the site conditions are harsh, with poor geological conditions and limited available space. Conventional erection devices do not have the lifting capacity for large equipment, while traditional electro-hydraulic methods have stringent requirements for the usage scenario, such as the need for a stable foundation in advance. As a result, in certain situations, the safety and reliability of the equipment cannot be fully guaranteed. Furthermore, the related equipment has a slow response speed, a long working cycle, and high maintenance requirements. It also carries greater risks when used outdoors or in restricted conditions. If the electric cylinder or hydraulic cylinder fails, it cannot be repaired quickly, thus limiting the applicability of the equipment.

[0003] Patent application No. 201910632502.9, filed on July 13, 2019, discloses a rotating and transporting vehicle for precast concrete components.

The tilting frame is rotatably connected to the frame, and the tilting cylinder controls the raising and lowering of the tilting frame.

The first reversing pulley group 42 and the second reversing pulley group 43 are located in the area between the first winch 41 and the tilting main support arm 30.

[0054] The first cable 45 is redirected to both sides of the tilting moving platform 3 via the first reversing pulley group 42 and the second reversing pulley group 43, and extends downward to connect with both ends of the tilting main support arm 30 after passing around the first fixed pulley group 44 at the top.

[0059] The third winch 6 is mounted on the first connecting frame 33, and the fourth cable 61 is connected to the erecting end 12.

[0060] The support base 31 has several slide rail blocks 35 on both sides of its bottom width, and the slide rail blocks 35 have grooves 351.

[0061] The top surface of the overall mobile platform 2 is provided with slide rails 21 on both sides, and the groove 351 is engaged with the slide rails 21; the bottom surface of the overall mobile platform 2 is provided with several moving wheels 7.

[0062] The tilting main support arm 30 includes several support walls 301, several rollers 302, roller shafts 303, several guide shafts 304, and guide wheels 305;

[0063] Several support walls 301 are projected to overlap and distributed at a certain distance, and are connected to the roller shaft 303 through several guide shafts 304; the support wall 301 is in the shape of an obtuse triangle, and perforations are opened on its obtuse angle end 3011, first acute angle end 3012 and second acute angle end 3013.

[0064] Several guide shafts 304 are respectively inserted through holes at the first acute angle end 3012 and the second acute angle end 3013, and the roller shaft 303 is inserted through the hole at the second acute angle end 3013; a roller 302 is provided between each pair of adjacent support walls 301, and several rollers 302 are inserted through roller shaft 303 and rotate around roller shaft 303;

[0065] Each of the guide shafts 304 has a guide wheel 305 at both ends; the guide wheels 305 are respectively disposed in a plurality of displacement grooves 323.

[0066] Several guide shafts 304 are located on the same horizontal line and are parallel to the overall moving platform 2; the second acute angle end 3013 is set towards the vertical end 12, and the roller 302 abuts against the vertical end 12 of the flipping worktable 1.

[0067] The flipping worktable 1 includes a first plate surface 13 and a second plate surface 14; the first plate surface 13 and the second plate surface 14 are set at an obtuse angle; the bottom surface of the first plate surface 13 is provided with a stepped clearance groove 131;

[0068] The second plate 14 has several through slots 141 along its length, and the positions of the several rollers 302 correspond one-to-one with the positions of the several through slots 141.

[0069] The overall mobile platform 2 is equipped with a control console 8 and a power distribution cabinet 9, both of which are located outside the reciprocating motion range of the flipping mobile platform 3.

[0070] Example 1:

[0071] See Figures 1-10 A large equipment tilting and erecting device includes: a tilting worktable 1, an integral moving platform 2, and a tilting moving table 3; the integral moving platform 2 is placed horizontally, the tilting worktable 1 is horizontally stacked on the integral moving platform 2, the fixed end 11 of the tilting worktable 1 is connected to one end of the integral moving platform 2, and rotates around an axis; the tilting moving table 3 is disposed on the integral moving platform 2 and can move horizontally back and forth along the direction of the integral moving platform 2; the tilting moving table 3 is provided with a tilting main support arm 30 that moves vertically back and forth; the tilting main support arm 30 is disposed below the erecting end 12 of the tilting worktable 1 and supports the erecting end 12.

[0072] In application, the tilting worktable 1 serves as a carrier for supporting objects. One end is fixed, while the other end can rotate around an axis, thereby converting the load from a horizontal to a vertical state. During the erection process, the tilting main support arm 30 on the tilting moving platform 3 rises upward, while the tilting moving platform 3 moves forward synchronously, thus lifting the erection end 12 of the tilting worktable 1. Compared to forms such as inclined support hydraulic rods, this type of device provides stronger support force because the lever arm between the component providing support power and the component supporting the object remains relatively short. Furthermore, it exhibits better stability during both erection and lowering processes, enabling it to provide stable erection functionality for large equipment. It also avoids the failure of the entire function due to damage to a single component, and the redundancy balances safety and reliability, meaning it is less prone to damage and requires less maintenance. Secondly, when erecting large equipment outdoors or in confined environments (such as on ships or test sites), objective conditions may make it difficult to set up large erection devices, preventing the use of conventional high-performance equipment. Therefore, better stability and ease of maintenance take precedence over erection capability. The required range of motion in this design is limited to the length of the tilting worktable 1 or the movement length of the tilting moving platform 3, and it has lower site requirements. Compared to hoisting methods, it requires less space and no foundation is needed. Therefore, the reliability, ease of maintenance, small operating radius, and low site requirements of this design make it better suited for work in confined environments.

[0073] Example 2:

[0074] The basic content is the same as in Example 1, except that:

[0075] See Figures 3-4 The flipping moving platform 3 includes a supporting base 31, a plurality of right-angled trapezoidal frames 32, and a first connecting frame 33 and a second connecting frame 34 connecting the right-angled trapezoidal frames 32. The plurality of right-angled trapezoidal frames 32 are symmetrically located on both sides of the width direction of the supporting base 31. The first connecting frame 33 is located in the middle of the hypotenuse 321 of the right-angled trapezoidal frame 32, and the second connecting frame 34 is located at the tail of the hypotenuse 321 of the right-angled trapezoidal frame 32. A plurality of displacement grooves 323 are vertically opened on the long right-angled side 322 of the right-angled trapezoidal frame 32. The two ends of the flipping main support arm 30 are respectively located in the displacement grooves 323, and the flipping main support arm 30 performs vertical reciprocating motion along the direction of the displacement grooves 323.

[0076] In application, the flipping moving table 3 is the main component that supports the flipping worktable 1. Its first connecting frame 33 is located in the middle of the hypotenuse 321 of the right trapezoidal frame 32. In this way, the space left at the front end can accommodate the vertical end 12 of the flipping worktable 1. Furthermore, the right trapezoidal frame 32 has good stability while minimizing the size of the device.

[0077] The tilting main support arm 30 moves vertically back and forth along the direction of the displacement groove 323. As is well known, straight up and down has the best stability and the structure that can achieve straight up and down is the simplest. Even if the power component that provides mechanical lifting fails, it can be temporarily replaced by other tools, such as jacks or even pads. It is a redundant safety design. In addition, auxiliary fixing parts such as pins can be set below the tilting main support arm 30 to provide an extra layer of protection for the support of the tilting main support arm 30.

[0078] Example 3:

[0079] The basic content is the same as in Example 2, except that:

[0080] See Figures 5-6The supporting base 31 is provided with a first traction group 4; the first traction group 4 includes a first winch 41, a first reversing pulley group 42, a second reversing pulley group 43, and a first fixed pulley group 44; the shaft of the first winch 41 is placed horizontally, and a first cable 45 is wound on it; the first winch 41 and the first reversing pulley group 42 are both located in the middle of the supporting base 31, the second reversing pulley group 43 is respectively located on both sides of the supporting base 31, and the first fixed pulley group 44 is respectively located at the top of the long right angle side 322; the first reversing pulley group 42 and the second reversing pulley group 43 are located in the area between the first winch 41 and the tilting main support arm 30; the first cable 45 is diverted to both sides of the tilting moving platform 3 via the first reversing pulley group 42 and the second reversing pulley group 43, and extends downwards after passing around the first fixed pulley group 44 at the top to connect with both ends of the tilting main support arm 30. The tilting and erecting device further includes a second traction group 5; the second traction group 5 includes a second winch 51, a second fixed pulley group 52, a third fixed pulley group 53, and a fourth fixed pulley group 54; the axis of the second winch 51 is horizontally arranged on the supporting base frame 31, and a second cable 55 and a third cable 56 are wound on the second winch 51; the winding directions of the second cable 55 and the third cable 56 are opposite; the second fixed pulley group 52 is arranged on the supporting base frame 31 on one side of the second winch 51; the third fixed pulley group 53 is fixedly arranged on the overall moving platform 2 below the fixed end 11; the fourth fixed pulley group 54 is arranged on the other side of the second winch 51 and is fixedly arranged on the overall moving platform 2; the second cable 55 is folded back through the second fixed pulley group 52 and the third fixed pulley group 53 and then fixedly connected to one end of the supporting base frame 31; the third cable 56 is folded back through the fourth fixed pulley group 54 and then fixedly connected to the other end of the supporting base frame 31. The tilting and erecting device also includes a third winch 6, on which a fourth cable 61 is wound; the third winch 6 is mounted on the first connecting frame 33, and the fourth cable 61 is connected to the erecting end 12.

[0081] In application, this device mainly uses a winch as its power source. As one of the most commonly used pieces of equipment in engineering machinery, the winch has a simple structure, good stability, and is easy to maintain and replace. In restricted conditions such as outdoors, other power sources, such as hydraulic rods, are basically impossible to carry replacement parts with the project. Even if the winch fails, it is relatively easy to repair or find a replacement, which makes this solution have good applicability and reliability.

[0082] In application, different functions are implemented by setting different winches to decompose each motion function of the device. In this way, even if a certain winch fails, other temporary measures can be taken to supplement it and avoid overall failure. At the same time, the winch can achieve linear control and has a fast response speed. It can accurately control the required erection angle and has good operation and control capabilities.

[0083] The erection process for this device is as follows:

[0084] Currently, the tilting worktable 1 is in a horizontal state. In this state, the relevant equipment that needs to be erected is placed on the bearing surface of the tilting worktable 1 and fixed. After the equipment is fixed, the first winch 41, the second winch 51, and the third winch 6 work synchronously. The first winch 41 is rotated to tighten the first cable 45, and the first reversing pulley group 42 and the second reversing pulley group 43 change the direction of the first cable 45 from vertical to both sides of the tilting moving platform 3, and raise the tilting main support arm 30 from top to bottom, so that the tilting worktable 1 rotates around the tilting axis; at the same time, the first winch 41... The second winch 51 tightens the second cable 55, which, after passing over the third fixed pulley block 53, pulls the tilting moving platform 3 forward on the overall moving platform 2. Simultaneously, the third cable 56 is released as the second cable 55 tightens; at this time, the third cable 56 is not under tension and is merely in a follow-up state. At the same time, the third winch 6 simultaneously releases the fourth cable 61; at this time, the fourth cable 61 is not under tension and is also merely in a follow-up state. Combining the synchronous operation of the first winch 41, the second winch 51, and the third winch 6, and the synchronous cable tightening and loosening, ultimately causes the tilting worktable 1 to rotate around its axis. Figure 11 The vertical working state is shown.

[0085] The process for leveling the device is as follows:

[0086] After completing the relevant operations of the equipment, the tilting worktable 1 needs to be leveled from its vertical position, allowing the first winch 41, second winch 51, and third winch 6 to work synchronously. Rotating the third winch 6 tightens the fourth cable 61, pulling the tilting worktable 1 to rotate around its axis. Simultaneously, the first winch 51 releases the first cable 55, causing the tilting main support arm 30 to descend. When the fourth cable 61 tightened by the third winch 6 gives the tilting worktable 1 a certain tilt angle, the inclined surface at the bottom of the tilting worktable 1 begins to contact the tilting main support arm 30. The second winch 51 tightens the third cable 56, pulling the tilting moving platform 3 backward on the overall moving platform 2. Simultaneously, the second cable 55 is released as the third cable 56 tightens. At this point, the second cable 55 is not under force and is merely moving along. Combining the synchronous operation of the first winch 41, second winch 56, and third winch 6, and the synchronous cable winding and unwinding, the tilting worktable 1 is finally rotated around its axis to... Figure 1 The horizontal working state is shown.

[0087] Furthermore, such as Figure 12 As shown, the first reversing pulley group 42 includes at least a first vertical fixed pulley 421 and a first horizontal fixed pulley 422, and the second reversing pulley group 43 includes at least a second vertical fixed pulley 431 and a second horizontal fixed pulley 432; as Figure 5 As shown, both sides of the supporting base 31 are arranged in a mirror image. The first cable 45 passes through the first vertical fixed pulley 421, the first horizontal fixed pulley 422, the second horizontal fixed pulley 432, the second vertical fixed pulley 431, and the first fixed pulley group 44 in sequence, thereby converting the tension of the first cable 45 from vertical in the middle to vertical tension on the tilting main support arm 30. Therefore, there are two first cables 45 to provide equal tension at both ends of the tilting main support arm 30. Similarly, there are two second cables 55, three third cables 56, and four fourth cables 61 to maintain the balance of the equipment's tension.

[0088] Example 4:

[0089] The basic content is the same as in Example 3, except that:

[0090] See Figures 7-10 The tilting main support arm 30 includes several support walls 301, several rollers 302, roller shafts 303, several guide shafts 304, and guide wheels 305; the several support walls 301 are distributed with overlapping projections and a certain distance between them, and are connected to the roller shafts 303 through several guide shafts 304; the support wall 301 is obtuse-angled triangle in shape, and its obtuse-angle end 3011, first acute-angle end 3012, and second acute-angle end 3013 are all provided with through holes; the several guide shafts 304 are distributed... A roller shaft 303 is inserted through the through holes at the first acute angle end 3012 and the second acute angle end 3013. A roller 302 is provided between each pair of adjacent support walls 301. Several rollers 302 are inserted through the roller shaft 303 and rotate around it. Guide wheels 305 are provided at both ends of several guide shafts 304. Several guide wheels 305 are respectively disposed within several displacement grooves 323. The guide shafts 304 are located on the same horizontal line and parallel to the overall moving platform 2. The second acute angle end 3013 faces the upright end 12, and the roller 302 abuts against the upright end 12 of the tilting worktable 1. The flipping worktable 1 includes a first plate surface 13 and a second plate surface 14; the first plate surface 13 and the second plate surface 14 are set at an obtuse angle; the bottom surface of the first plate surface 13 is provided with a stepped clearance groove 131; and the second plate surface 14 is provided with a plurality of through grooves 141 along its length.

[0091] In application, the segmented structure formed by several support walls 301 can distribute the load-bearing capacity among various parts, and also facilitate maintenance. The triangular support wall 301 has good stability, making it more stable when supporting large equipment, while the roller 302 can reduce friction during movement.

[0092] The first plate 13 and the second plate 14 of the flipping worktable 1 are set at an obtuse angle because one end of the flipping worktable 1 is fixed. The distance from the fixed point to the other end is long, which will cause stress concentration at the fixed point and pose a certain risk of breakage. Therefore, the plate surfaces of the flipping worktable 1 are set at a certain angle to transfer the stress concentration point. This design can also reduce the movement path of the flipping worktable 1 when it is erected, and increase the ease of use.

[0093] Furthermore, the second plate surface 14 is provided with a plurality of through slots 141 along its length, and as shown in the figure Figure 9 The multiple circular cutouts shown can reduce the weight of the flipping worktable 1 and can also be used as fixed points for supporting the fixed points.

[0094] Although embodiments of the present invention have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
