[0034] This invention provides a steel cable type pole slewing support mechanism with anti-overturning function. Compared with the prior art, it has the following advantages:
[0035] 1. This invention uses an anti-tipping mechanism to apply the deflection force to the fixed support rod section at the bottom of the slewing lower support, thereby increasing the support points for the slewing support and slewing upper support after deflection. By supporting the safety ring and slewing upper support at multiple points, the anti-tipping capability of the slewing support rod section and boom is improved. Furthermore, by integrating most of the anti-tipping mechanism's structure (except for the mounting sleeve) onto the anti-tipping rod, and facilitating overall disassembly and assembly of the anti-tipping mechanism, it allows for easy maintenance and replacement by workers at heights, ensuring long-term use without affecting its anti-tipping function.
[0036] 2. When the anti-roll ring presses the piston rod of the second auxiliary component by its downward tilting side, the piston block of the first auxiliary component drives the piston rod to press the upward side of the anti-roll ring downward, thereby helping to maintain the anti-roll ring in a horizontal and stable state. This, in turn, helps to maintain the safety ring and the rotating upper seat in a horizontal and stable state, thus improving the anti-rollover effect.
[0037] 3. By setting an annular groove and an annular slider, the anti-tilting ring and the annular slider can rotate relative to each other, so as not to affect the normal rotation and hoisting of the boom, and to facilitate anti-tipping operations on the slewing seat and boom.
[0038] 4. The present invention ensures that the hydraulic force borne by the piston rods at diagonal positions is the same, thereby making it easier to maintain the anti-tilt ring and the slewing upper seat in a horizontal and stable state, improving the stability of the slewing upper seat and the slewing rod section, reducing the degree of shaking caused by looseness between structures during long-term use, and thus improving the stability of the slewing support.
[0039] Hydraulic oil is supplied through pipes connected to the outside of conduits and valve bodies to improve the stability of the anti-tilt ring and slewing upper seat, thereby improving the stability of the slewing upper seat and slewing boom joint in a horizontal state.
[0040] 5. The present invention supports the bottom of the second connecting ring through the limiting component of the anti-tipping mechanism, eliminating the need for manual support of the anti-tipping mechanism when fixing the first and second fixing flanges, thus facilitating actual operation.
[0041] The positioning rod and positioning groove facilitate the rotational limitation of the first and second connecting rings, preventing them from deflecting along with the anti-roll bar, etc., without affecting the insertion of the first connecting ring, etc., into the mounting sleeve. In addition, the stability of the first support ring is improved through screw holes, thereby improving the stability of the anti-rollover mechanism. Attached Figure Description

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0061] Example 1: Please refer to Figures 1-4 , Figure 13 and Figure 14 A steel rope type pole slewing support mechanism with anti-overturning function includes a fixed pole section 1, a lower slewing seat 2, a slewing support 6, an upper slewing seat 3 and a slewing pole section 4. The tops of the upper slewing seat 3, the slewing support 6 and the lower slewing seat 2 are all provided with interconnected circular central holes 9.
[0062] The bottom of the lower slewing seat 2 is fixedly connected to the top of the fixed boom section 1. The bottom fixed end of the slewing support 6 is fixedly connected to the top of the lower slewing seat 2. The top rotating end of the slewing support 6 is fixedly connected to the bottom of the upper slewing seat 3. The top of the upper slewing seat 3 is fixedly connected to the bottom of the slewing boom section 4, so that the slewing boom section 4 can rotate relative to the fixed boom section 1. The upper slewing seat 3 can rotate relative to the lower slewing seat 2 through the slewing support 6, thereby allowing the slewing boom section 4 to rotate relative to the fixed boom section 1, so that the boom can rotate after the slewing boom section 4 is connected to the external boom. It also includes:
[0063] A safety ring 5 abuts against the bottom of the lower rotating seat 2, and the top of the safety ring 5 is fixedly connected to the upper rotating seat 3 via a screw 10, so that when the upper rotating seat 3 deflects, the safety ring 5 abuts against the bottom of the lower rotating seat 2. The bottom of the safety ring 5 is provided with an anti-tipping mechanism 7 extending into the fixed support section 1. The anti-tipping mechanism 7 includes:
[0064] The anti-roll bar 8 is detachably installed at the bottom of the safety ring 5 and extends into the fixed rod section 1. The side wall of the anti-roll bar 8 is fixedly fitted with an anti-roll ring 794.
[0065] The mounting sleeve 73 is fixedly installed on the inner side of the fixed rod section 1. The inner side of the mounting sleeve 73 is provided with a first support ring 795 and a second support ring 793 arranged in parallel. The inner walls of the first support ring 795 and the second support ring 793 are both fitted onto the side walls of the anti-roll bar 8. The top of the first support ring 795 and the bottom of the second support ring 793 are respectively provided with a first auxiliary component 701 and a second auxiliary component 70, which are arranged in a ring array.
[0066] The screws 10 used to fix the safety ring 5 are arranged along the inner wall of the circular central hole 9, and the outer diameter of the safety ring 5 is larger than the diameter of the circular central hole 9 of the rotating lower seat 2.
[0067] In practice, during normal operation of the slewing boom section 4 and the boom, the safety ring 5 rotates synchronously with the screw 10 and the upper slewing seat 3. When the slewing boom section 4 experiences an abnormal unbalanced bias load or is subjected to a lateral force biased towards the vertical direction, and this lateral force exceeds the load that the slewing support 6 can withstand, the slewing support 6 will be biased to one side. This will cause the safety ring 5 to be biased to one side through the screw 10, so that the side of the safety ring 5 away from the overturning direction abuts against the bottom of the lower slewing seat 2. This transfers the lateral force of the overturning load to the lower slewing seat 2, preventing the boom and jib above the slewing boom section 4 from overturning as a whole after the slewing support 6 is overloaded, thus preventing the occurrence of serious unsafe events.
[0068] When the safety ring 5 deflects with the upper slewing seat 3, the safety ring 5 causes the anti-tilt bar 8 and the anti-tilt ring 794 to deflect accordingly. Since the first support ring 795 and the second support ring 793 are supported by the mounting sleeve 73, the first connecting ring 78 and the second connecting ring 75, the safety ring 5 applies the deflection force to the fixed slewing rod section 1 at the bottom of the lower slewing seat 2 when it deflects. This increases the number of support points for the slewing support 6 and the upper slewing seat 3 after deflection, so that the safety ring 5 and the upper slewing seat 3 are supported by multiple points, thereby further improving the anti-tipping ability of the slewing slewing rod section 4 and the boom. Simultaneously, when the anti-roll bar 8 tilts with the safety ring 5, it causes the anti-roll ring 794 to tilt. During this process, the anti-roll ring 794 squeezes the piston rod 7014 of the second auxiliary component 70 on the downward tilting side, thereby causing the hydraulic oil in the cylinder 7011 of the second auxiliary component 70 to enter the cylinder 7011 of the first auxiliary component 701 at the diagonal position through the hydraulic pipe 702. This causes the anti-roll ring 794 to be squeezed downward from the upward side and from the top of the anti-roll ring 794. By using the principle of the anti-roll ring 794 tilting downward on one side and upward on the other side, the tilting of the anti-roll ring 794 and the anti-roll bar 8 is suppressed, improving the stability of the anti-roll bar 8 and the safety ring 5, thereby reducing the risk of overturning.
[0069] Under the constraints of the safety ring 5 and the anti-tipping mechanism 7, even if the slewing boom section 4 and the slewing support 6 do not overturn, the slewing boom section 4 and the boom connected to it are relatively heavy. During long-term use, the slewing support 6 is prone to loosening and swaying. Therefore, since hydraulic oil can flow in the first auxiliary component 701 and the second auxiliary component 70 at diagonal positions, and hydraulic oil is provided at the top and bottom of the piston block 7013, the first auxiliary component 701 and the second auxiliary component 70 at diagonal positions provide the same support force to the anti-tipping ring 794. Through the first auxiliary component 701 and the second auxiliary component 70 arranged in a ring array, the anti-tipping ring 794 is kept in a horizontal state, which makes it easier for the anti-tipping rod 8, the safety ring 5 and the slewing upper seat 3 to maintain a vertical state, thereby improving the slewing stability of the slewing boom section 4 and the boom.
[0070] The anti-roll bar 8 is disassembled and assembled by the first fixed flange 71 and the second fixed flange 72, thereby disassembling and assembling the anti-roll mechanism 7. Since the slewing support 6 and the slewing boom section 4 are usually quite high, the anti-roll mechanism 7 is designed as a whole, which is convenient for overall disassembly and assembly, thus facilitating high-altitude operation and not affecting the actual anti-roll use.
[0071] Please see Figures 8-11 The first support ring 795 is located on top of the second support ring 793. The first auxiliary component 701 and the second auxiliary component 70 are arranged facing each other and have the same structure. The first auxiliary component 701 includes:
[0072] The cylinder body 7011 is fixedly mounted on the top of the first support ring 795. The inner wall of the cylinder body 7011 is fitted with a piston block 7013. The inside of the cylinder body 7011 and the top and bottom of the piston block 7013 are filled with hydraulic oil.
[0073] The piston rod 7014 is fixedly disposed at the bottom of the piston block 7013 and extends to the bottom of the first support ring 795. The top of the first support ring 795 is provided with a through hole for fitting the piston rod 7014. The side walls of the piston rod 7014 and the piston block 7013 and the inner wall of the cylinder 7011 are all designed with dynamic sealing.
[0074] The first auxiliary component 701 also includes;
[0075] Hinge 7015, the hinge end of hinge 7015 is fixedly connected to the end of piston rod 7014;
[0076] The conduit 7012 is fixedly installed on the outer wall of the cylinder 7011 and the hydraulic pipe 702. The conduit 7012 on the outer wall of the cylinder 7011 is located on the side of the piston block 7013 near the piston rod 7014. The outer wall of the conduit 7012 is provided with a valve body.
[0077] The anti-tipping mechanism 7 also includes:
[0078] Hydraulic pipe 702 is used to connect the cylinder 7011 of the first auxiliary component 701 and the second auxiliary component 70 at diagonal positions of the first support ring 795 and the second support ring 793, so that hydraulic oil can flow in the cylinder 7011 of the first auxiliary component 701 and the second auxiliary component 70 at diagonal positions, so that when the anti-roll ring 794 deflects and presses the second auxiliary component 70 with the anti-roll bar 8, the first auxiliary component 701 at diagonal positions presses the anti-roll ring 794 downward from the top of the anti-roll ring 794;
[0079] An annular groove 703 is provided at the top and bottom of the anti-tilt ring 794. An annular slider is placed inside the annular groove 703. The top and bottom of the annular slider are connected to the fixed end of the hinge 7015.
[0080] In practical implementation, when the safety ring 5 tilts as the upper rotating seat 3 deflects, the safety ring 5 drives the anti-tilt rod 8 and the anti-tilt ring 794 to tilt via the first fixed flange 71 and the second fixed flange 72. During this process, due to the deflection of the anti-tilt ring 794, one side of the anti-tilt ring 794 tilts downward, and the opposite side of the anti-tilt ring 794 tilts upward. Accordingly, the downward tilting side of the anti-tilt ring 794 will press the piston rod 7014 at the top of the second support ring 793, thereby causing the piston rod 7014 of the second auxiliary assembly 70 to drive the piston block 7013 at its bottom. The hydraulic oil in the part is squeezed, so that the hydraulic oil is delivered through the hydraulic pipe 702 to the cylinder 7011 of the first auxiliary component 701 at the diagonal position, so that the hydraulic oil squeezes the piston block 7013 of the first auxiliary component 701 downward, so that the piston block 7013 of the first auxiliary component 701 drives the piston rod 7014 to squeeze the upward side of the anti-roll ring 794 downward, in order to help maintain the anti-roll ring 794 in a horizontal and stable state, thereby helping to maintain the safety ring 5 and the rotating upper seat 3 in a horizontal and stable state, so as to improve the anti-rollover effect.
[0081] By setting an annular groove 703 and an annular slider, the anti-tilting ring 794 and the annular slider can rotate relative to each other. This ensures that the safety ring 5, anti-tilting rod 8, and anti-tilting ring 794 rotate synchronously with the slewing upper seat 3, thus not affecting the normal rotation and lifting of the boom, and facilitating anti-tilting operations on the slewing upper seat 3 and the boom. The piston rod 7014 is connected to the annular slider through the hinge 7015, ensuring that the piston rod 7014 stably applies force to the anti-tilting ring 794 after tilting, improving the stability of the anti-tilting operation.
[0082] The anti-tilt ring 794 is supported at the bottom and top by the first auxiliary component 701 and the second auxiliary component 70 arranged in a ring array. Hydraulic oil can circulate in the cylinder 7011 of the first auxiliary component 701 and the second auxiliary component 70 at diagonal positions. In addition, the top and bottom of the piston block 7013 are filled with hydraulic oil. Thus, during long-term use, the hydraulic force provided to the piston rod 7014 at diagonal positions is the same, which helps to keep the anti-tilt ring 794 and the slewing upper seat 3 in a horizontal and stable state, improves the stability of the slewing upper seat 3 and the slewing lever section 4, and reduces the degree of shaking caused by looseness between structures during long-term use, thereby improving the stability of the slewing support. Hydraulic oil is supplied through conduit 7012 and externally to the valve body via a pipeline. When the pressure of the hydraulic oil in cylinder 7011 is insufficient to stably support the slewing bearing 6, hydraulic oil is added through conduit 7012 to the space at the top and bottom of piston block 7013 within cylinder 7011. This increases the hydraulic oil pressure, thereby improving the stabilizing support effect on anti-tilt ring 794 and slewing upper seat 3, and thus enhancing the stability of slewing upper seat 3 and slewing lever section 4 in a horizontal state. When adding hydraulic oil, the pressure difference between the top and bottom of piston block 7013 must be adjusted accordingly to ensure that piston rod 7014 stably supports anti-tilt ring 794.
[0083] When the anti-tilt ring 794 is kept in a horizontal and stable state by the first auxiliary component 701 and the second auxiliary component 70 arranged in a ring array, angle sensors are usually installed at the slewing support 6 and the slewing boom section 4 to monitor the tilt angle of the slewing boom section 4. The deflection angle of the slewing boom section 4 under normal operation monitored by the angle sensor makes it easy to determine the amount of hydraulic oil to be added or reduced in the first auxiliary component 701 and the second auxiliary component 70, which is convenient for actual operation. The angle sensor is existing technology and is not shown in the figure, so it will not be described in detail here.
[0084] By allowing hydraulic oil to circulate between the first auxiliary component 701 and the second auxiliary component 70 at diagonal positions, the anti-tipping ring 794 can be supported against overturning without additional power input, making it convenient for use in high-altitude operations.
[0085] Please see Figure 6 The anti-tipping mechanism 7 further includes:
[0086] The connecting plate 792 is fixedly arranged in a ring array on the outer wall of the second support ring 793. The lower inner side of the connecting plate 792 is fixedly provided with a fixing post 791 to fix the hydraulic pipes 702 arranged in the ring array through the fixing post 791. The end of the hydraulic pipe 702 near the fixing post 791 is designed to be bent so that the hydraulic pipes 702 arranged in the ring array are arranged in an alternating pattern.
[0087] In practice, the fixed column 791 is connected to the second support ring 793 to limit the movement of multiple hydraulic pipes 702, thereby ensuring the stability of the installation of the hydraulic pipes 702 and preventing the hydraulic pipes 702 from becoming messy and affecting high-altitude operations.
[0088] Example 2: Please refer to Figures 4-7 The difference between this embodiment and embodiment one is that the outer walls of the first support ring 795 and the second support ring 793 are respectively fixedly sleeved with the first connecting ring 78 and the second connecting ring 75, and the outer walls of the first connecting ring 78 and the second connecting ring 75 are both fixedly equipped with positioning rods 77 arranged in a ring array.
[0089] The inner wall of the mounting sleeve 73 is provided with a ring array of positioning grooves 79. The inner wall of the positioning grooves 79 is adapted to the side wall of the positioning rod 77 so that the first connecting ring 78 and the second connecting ring 75 can be inserted into the inner side of the mounting sleeve 73 along the bottom of the mounting sleeve 73, while limiting the rotation of the first connecting ring 78 and the second connecting ring 75.
[0090] The anti-tipping mechanism 7 also includes:
[0091] A limiting component 74 is disposed at the lower end of the outer wall of the mounting sleeve 73 and arranged in a circular array to support the bottom of the second connecting ring 75. The limiting component 74 includes:
[0092] The limiting seat 741 is fixedly disposed on the lower end of the outer wall of the mounting sleeve 73. The limiting frame 743 is sleeved inside the limiting seat 741. The limiting plate 742 is fixedly sleeved on the inner wall of the limiting frame 743. The two ends of the limiting plate 742 extend to the inner side of the mounting sleeve 73 and the side of the limiting seat 741 away from the mounting sleeve 73, respectively.
[0093] The outer frame 744 is fixedly sleeved on the side wall of the limiting plate 742 located away from the mounting sleeve 73 of the limiting seat 741. The limiting seat 741 has a limiting through groove for sleeved on the limiting frame 743 and the limiting plate 742.
[0094] The anti-tipping mechanism 7 also includes:
[0095] The screw holes 76 are formed on the outer wall of the mounting sleeve 73 and are arranged in a ring array. The screw holes 76 extend into the first connecting ring 78 and the second connecting ring 75 and are arranged in a staggered manner with the positioning rod 77.
[0096] The anti-tipping mechanism 7 also includes:
[0097] The first fixed flange 71 is fixedly installed at the bottom of the safety ring 5;
[0098] The second fixed flange 72 is fixedly installed on the top of the anti-roll bar 8. The second fixed flange 72 is fixedly connected to the first fixed flange 71 by bolts to connect the anti-roll bar 8 and the safety ring 5.
[0099] In practical implementation, most of the structure of the anti-tipping mechanism 7, except for the mounting sleeve 73, the limiting component 74, and the first fixed flange 71, is integrated onto the anti-tipping rod 8. This allows for the overall disassembly and assembly of the anti-tipping mechanism 7 by removing and installing the first fixed flange 71 and the second fixed flange 72, facilitating high-altitude operations. Specifically, during installation, the anti-tipping rod 8 is placed inside the fixed support section 1 along the cutout on its side wall, positioned at the bottom of the mounting sleeve 73. Then, along the engagement position of the positioning rod 77 and the positioning groove 79, the first connecting ring 78 and the second connecting ring 75 are moved... Move the device into the mounting sleeve 73, then push the limiting plate 742 inward to support the bottom of the second connecting ring 75. This eliminates the need for manual support of the anti-tipping mechanism 7 when fixing the first fixing flange 71 and the second fixing flange 72, simplifying operation. Then, connect and fix the first fixing flange 71 and the second fixing flange 72 with bolts to install the anti-tipping mechanism 7. Finally, secure the first connecting ring 78, the second connecting ring 75, and the mounting sleeve 73 with external bolts passing through the screw holes 76, thereby improving the stability of the first support ring 795 and the second support ring 793. Disassembly is performed by reversing the operation. This facilitates replacement and maintenance of the anti-tipping mechanism 7 at heights, simplifying operation without affecting its actual anti-tipping function.
[0100] The positioning rod 77 and positioning groove 79 limit the movement of the first connecting ring 78, the second connecting ring 75, and the mounting sleeve 73, facilitating the rotational limitation of the first connecting ring 78 and the second connecting ring 75 and preventing them from deflecting along with the anti-roll bar 8, etc., without affecting the insertion of the first connecting ring 78, etc., into the mounting sleeve 73. In addition, the first connecting ring 78 and the second connecting ring 75 are fixed by external bolts through the screw hole 76, improving the stability of the first support ring 795 and the second support ring 793, thereby improving the stability of the anti-rollover mechanism.
