Description

Technical Field

[0001] The present invention relates to the technical field of bridge structures or building technologies, and more particularly, to a split-type automatic assembly spherical hinge. Background Art

[0002] In recent years, the high-speed rail and highway networks in China have developed rapidly. Inevitably, many newly built railway or highway bridges cross the existing railway and highway networks. If a bridge is directly built above the existing highway or railway network, it will not only affect the traffic safety of existing vehicles but also the construction period of the bridge. Therefore, to solve the above problems, the method of spherical hinge rotation construction is increasingly adopted. The load-bearing system of spherical hinge rotation construction mainly consists of an upper spherical hinge, a lower spherical hinge, and a non-metallic slide plate, etc. Among them, the lower spherical hinge is connected to the ground pier and abutment concrete and mainly plays a load-bearing role. The upper spherical hinge is connected to the bridge pier, and by pulling the bridge pier, relative rotation is generated between the upper and lower spherical hinges. The non-metallic slide plate bears the pressure between the upper and lower seat plates, and its friction coefficient is small, which can effectively reduce the friction resistance during rotation. The upper spherical hinge and the bridge pier achieve the purpose of bridge rotation under the action of traction force.

[0003] In recent years, the span of bridges has gradually increased, and the tonnage of bridge rotation has increased from the conventional several thousand tons to hundreds of thousands of tons. With the increase of the bearing pressure, the diameter of the spherical hinge is also getting larger and larger. However, the width and height limits of many bridges and mountain caves make it impossible for the spherical hinge to be transported, and the freight cost also increases accordingly, which affects the construction period at the same time. Although the existing assembled combined spherical hinge can partly solve the above problems, due to the large self-weight and volume of the spherical hinge and most of the split spherical hinges are bolt-connected, it is extremely difficult to assemble on-site during construction, often resulting in the inability to guarantee the quality of rotation construction. Therefore, how to reduce the assembly difficulty of the spherical hinge while ensuring its easy transportation is an urgent problem to be solved.

[0004] Patent CN107227683A involves that the frame is connected to the rear end of the carrier vehicle body through a rotating pair, the direction of the rotating pair is perpendicular to the driving direction of the carrier vehicle, the bottom of the cylinder barrel of the erection driving cylinder is connected to the bottom of the carrier vehicle through a spherical hinge, the top of its extension rod is connected to the frame through a spherical hinge, the bridge body retracting and deploying device is arranged in the frame and is connected to the frame through a moving pair, and the upper parts of two adjacent foldable frame-type bridge body units are connected through a foldable pull rod, the front and rear of its foldable floor unit are connected through a pin shaft, and the foldable pull rod can be folded down or deployed, which makes the suspension bridge easy to transport and fold to a certain extent, and the use of spherical hinges makes the suspension bridge more flexible, but it still does not solve the problems of difficult transportation of the spherical hinge when used as a part of bridge construction and large splicing difficulty. Summary of the Invention

[0005] In view of this, the present invention aims to provide a split-type automatic assembling spherical hinge to solve the problems existing in the prior art, namely, due to the bearing capacity requirement of the spherical hinge, the diameter of the spherical hinge is too large, resulting in inconvenient transportation and great difficulty in assembling.

[0030] The following will use the terms that those skilled in the art usually use to convey the essence of their work to other technicians in the art to describe the inventive concept of the present disclosure. However, these inventive concepts can be embodied in many different forms and should not be considered limited to the embodiments described herein.

[0031] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0032] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0033] The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0034] This embodiment is directed to the ball hinge of the bearing device. The same as the conventional ball hinge of the bearing device, the overall structure is composed of an upper ball hinge, a lower ball hinge and a non-metallic sliding plate.

[0035] In the prior art, with the increase of the bridge span, the turning weight of the bridge doubles, which makes the bearing pressure of the ball hinge bearing device increase. Therefore, the diameter of the ball hinge is getting larger and larger to meet the bearing pressure requirement. However, the width and height limits of many bridges and mountain caves make it impossible for the ball hinge to be transported through, and the freight also increases accordingly, which affects the construction period at the same time. Although the existing assembled and combined ball hinge can partially solve the above problems, due to the large self-weight and volume of the ball hinge and the fact that most of the split ball hinges are bolt-connected, it is extremely difficult to align and assemble on-site during construction, often resulting in the inability to guarantee the quality of the turning construction.

[0036] To solve the problem in the prior art that due to the bearing force requirement of the spherical hinge, the diameter of the spherical hinge is too large, resulting in inconvenient transportation and great assembly difficulty; this embodiment proposes a split-type automatic assembly spherical hinge, including a spherical hinge body 1, spherical hinge segments 2 and a driving device 9. The spherical hinge segments 2 are detachably connected to the spherical hinge body 1. The spherical hinge body 1 includes a pin shaft sleeve 6, and the pin shaft sleeve 6 is arranged on the upper side of the spherical hinge body 1. The driving device 9 is connected to the pin shaft sleeve 6 through a flange fixing device 7. The driving device 9 can drive the steel rope 10 to move, so that the spherical hinge segments 2 rotate around the spherical hinge body 1. Among them, the spherical hinge includes spherical hinge ribs 4 for strengthening the bearing capacity of the spherical hinge, improving the stiffness and strength of the spherical hinge. At the same time, according to the position of the spherical hinge ribs 4, it is convenient to divide the spherical hinge body 1 and the spherical hinge segments 2. The spherical hinge ribs 4 include spherical hinge ring ribs 41 and spherical hinge vertical ribs 42, and the spherical hinge ring ribs 41 and the spherical hinge vertical ribs 42 are arranged alternately. The spherical hinge ring ribs 41 are annular, and the spherical hinge vertical ribs 42 are arranged in a curve. Figure 2 Taking the figure shown as an example, the spherical hinge vertical ribs 42 include a first vertical rib 421, a second vertical rib 422, a third vertical rib 423 and a fourth vertical rib 424. The first vertical rib 421, the second vertical rib 422, the third vertical rib 423 and the fourth vertical rib 424 are arranged in a circumferential distribution. The intersection of the first vertical rib 421, the second vertical rib 422, the third vertical rib 423 and the fourth vertical rib 424 is the center of the circle. The first vertical rib 421, the second vertical rib 422, the third vertical rib 423 and the fourth vertical rib 424 are all arranged alternately with the spherical hinge ring ribs 41. The spherical hinge vertical ribs 42 also include a first folded vertical rib 425 and a second folded vertical rib 426. The first folded vertical rib 425 and the second folded vertical rib 426 are both arranged parallel to the third vertical rib 423. In this embodiment, the upper side refers to the upper part in the figure, without any other implied meaning.

[0037] The split-type spherical hinge can effectively reduce the transportation difficulty. During transportation, changing the position of the spherical hinge segments 2 and the spherical hinge body 1 can effectively reduce the space occupancy rate of the spherical hinge, making the spherical hinge convenient for transportation, thereby reducing the cost during the transportation of the spherical hinge, effectively improving the working efficiency of the spherical hinge, and at the same time being beneficial to the splicing of the spherical hinge, reducing the splicing difficulty of the spherical hinge, shortening the construction period of the spherical hinge. Dividing the spherical hinge into three parts according to the spherical hinge ring ribs 41 and the spherical hinge vertical ribs 42 is beneficial to the combination and folding of the spherical hinge, and at the same time can avoid the possibility of the bearing pressure of the spherical hinge decreasing caused by excessive disassembly.

[0038] The ball hinge split part 2 is connected to the ball hinge body 1 through a rotating mechanism 3. The rotating mechanism 3 is used to position and support the ball hinge split part 2 when it rotates around the ball hinge body 1 to the first angle ɑ, and is convenient for the folding between the ball hinge split part 2 and the ball hinge body 1. The first angle ɑ refers to the angle at the fixed position required during the rotation of the ball hinge split part 2 around the ball hinge body 1. The range of ɑ is from 0° to 90°. Among them, the rotating mechanism 3 includes a hinge pin shaft 31 and a hinge sleeve 32. The inner side wall of the hinge sleeve 32 is connected to the outer side wall of the hinge pin shaft 31. The hinge pin shaft 31 is arranged on the upper side of the ball hinge body 1, and the hinge sleeve 32 is arranged on the upper side of the ball hinge split part 2. When the ball hinge split part 2 rotates around the ball hinge body 1, the hinge sleeve 32 can rotate around the hinge pin shaft 31. When the ball hinge split part 2 rotates around the ball hinge body 1 to the first angle ɑ, the hinge pin shaft 31 is fixedly connected to the hinge sleeve 32 through a pin 33. The rotating mechanism 3 is used to position the ball hinge body 1 and the ball hinge split part 2 at the required position; the hinge pin shaft 31 includes a pin shaft hole 311, and the hinge sleeve 32 includes a sleeve hole 321. When the ball hinge split part 2 rotates around the ball hinge body 1 to the first angle ɑ, the pin shaft hole 311 of the hinge pin shaft 31 is aligned with the sleeve hole 321 of the hinge sleeve 32, that is, the center line of the pin shaft hole 311 and the center line of the sleeve hole 321 are on the same straight line. A pin 33 is arranged in the pin shaft hole 311 and the sleeve hole 321. The pin 33 is used to fix the hinge pin shaft 31 and the hinge sleeve 32 after they are connected, and is used to position the ball hinge body 1 and the ball hinge split part 2 at the first angle ɑ; when the ball hinge split part 2 rotates and folds around the ball hinge body 1, the pin 33 is taken out, and the hinge pin shaft 31 rotates around the hinge sleeve 32. Furthermore, the ball hinge split part 2 rotates around the ball hinge body 1 through the rotating mechanism 3. In this embodiment, "alignment" means that the center line of the pin shaft hole 311 and the center line of the sleeve hole 321 are on the same straight line.

[0039] Through the setting of the rotating mechanism 3, the ball hinge split part 2 and the ball hinge body 1 can be effectively fixed at the required first angle ɑ position, ensuring the smooth automatic splicing and alignment of the ball hinge, reducing the splicing difficulty of the ball hinge, and the mutual cooperation between the hinge pin shaft 31 and the hinge sleeve 32 can further enhance the installation stability of the ball hinge split part 2 and the ball hinge body 1, and enhance the safety during the use of the ball hinge.

[0040] The ball hinge split part 2 includes a left ball hinge split part 21 and a right ball hinge split part 22. Hinge sleeves 32 are provided on the upper sides of both the left ball hinge split part 21 and the right ball hinge split part 22. The left ball hinge split part 21 is connected to the hinge pin shaft 31 on the left side of the ball hinge body 1 through the hinge sleeve 32, and the right ball hinge split part 22 is connected to the hinge pin shaft 31 on the right side of the ball hinge body 1 through the hinge sleeve 32. The ball hinge split part 2 is provided with a wire drawing hole 5, which is used to facilitate the rotation of the ball hinge split part 2 around the ball hinge body 1 under the traction of the driving device 9. The wire drawing hole 5 includes a first wire drawing hole 51 and a second wire drawing hole 52. The first wire drawing hole 51 is provided at the upper end of the left ball hinge split part 21, and the second wire drawing hole 52 is provided at the upper end of the right ball hinge split part 22. Among them, the discrimination method of the automatic assembly ball hinge is divided into two methods: five-piece split and three-piece split. Among them, in the five-piece split method, the rotating mechanism 3 of the ball hinge is symmetrically and evenly arranged at any position within the range of the first dotted line frame A with the first vertical rib 421 as the center line, and the rotating mechanism 3 is symmetrically and evenly arranged at any position within the range of the second dotted line frame B with the first vertical rib 421 as the center line. Two rotating mechanisms 3 are symmetrically arranged within the first dotted line frame A with the first vertical rib 421 as the center line, and two rotating mechanisms 3 are symmetrically arranged within the second dotted line frame B with the first vertical rib 421 as the center line. Among them, the hinge sleeves 32 of the rotating mechanism 3 are symmetrically and evenly arranged on the ball hinge split part 2 at any position within the range of the first dotted line frame A with the first vertical rib 421 as the center line and on the ball hinge split part 2 at any position within the range of the second dotted line frame B with the first vertical rib 421 as the center line. The hinge pin shafts 31 of the rotating mechanism 3 are symmetrically and evenly arranged on the ball hinge body 1 at any position within the range of the first dotted line frame A with the first vertical rib 421 as the center line and on the ball hinge body 1 at any position within the range of the second dotted line frame B with the first vertical rib 421 as the center line. Preferably, the hinge sleeves 32 of the ball hinge in the five-piece split method are respectively arranged on the ball hinge split part 2 at the intersection of the second vertical rib 422 and the ball hinge ring rib 41 and on the ball hinge split part 2 at the intersection of the fourth vertical rib 424 and the ball hinge ring rib 41. The hinge pin shafts 31 of the ball hinge in the five-piece split method are respectively arranged on the ball hinge body 1 at the intersection of the second vertical rib 422 and the ball hinge ring rib 41 and on the ball hinge body 1 at the intersection of the fourth vertical rib 424 and the ball hinge ring rib 41. The hinge sleeves 32 of the ball hinge in the three-piece split method are respectively arranged on the ball hinge split part 2 at the first folded vertical rib 425 and the second folded vertical rib 426. The hinge pin shafts 31 of the ball hinge in the three-piece split method are respectively arranged on the ball hinge body 1 at the first folded vertical rib 425 and the second folded vertical rib 426. Among them, in this embodiment, the first dotted line frame A and the second dotted line frame B are Figure 2At the position indicated by the dotted box shown, through simulation, it is found that within this range, the ball hinge split part 2 can normally rotate around the ball hinge body 1. The widths of the first dotted box A and the second dotted box B are both the distance between the intersection of the first vertical rib 421 and the ball hinge ring rib 41 and the intersection of the second vertical rib 422 and the ball hinge ring rib 41. The lengths of the first dotted box A and the second dotted box B are both the distance between the intersection of the second vertical rib 422 and the ball hinge ring rib 41 and the intersection of the end of the fourth vertical rib 424 close to the first dotted box A and the ball hinge ring rib 41.

[0041] Through various settings of the resolution method for automatically assembling the ball hinge, the applicable range of the split ball hinge can be effectively increased, the applicability of the ball hinge in different environments can be improved, the splicing efficiency of the ball hinge can be enhanced, the splicing difficulty of the ball hinge can be reduced, the transportation cost of the ball hinge can be decreased. At the same time, the flexibility of ball hinge splicing can be greatly improved.

[0042] The flange fixing device 7 includes a flange 71 and a platform 72. One end of the flange 71 is connected to the side of the pin shaft sleeve 6 away from the ball hinge body 1, and the other end of the flange 71 is detachably connected to the platform 72 by bolts. A driving device 9 is arranged on the upper side of the platform 72. A platform wire passing hole 73 is arranged in the plane of the platform 72. The platform wire passing hole 73 is a through hole for facilitating the steel rope 10 to pass through. A wire pulling pulley 8 is arranged on the lower side of the platform 72. The wire pulling pulley 8 is used to reduce the friction between the steel rope 10 and the platform 72. The flange 71 is composed of two upper and lower buckled flange plates 71. The platform 72 is a flat plate. The platform 72 is used to provide a position for the installation of the driving device 9. At least one wire pulling pulley 8 is arranged. The wire pulling pulley 8 includes a first pulley 81 and a second pulley 82. The first pulley 81 is arranged at the left end of the lower side of the platform 72, and the second pulley 82 is arranged at the right end of the lower side of the platform 72. Both the first pulley 81 and the second pulley 82 are used to reduce the friction between the steel rope 10 and the platform 72. Among them, the length of the pin shaft sleeve 6 is greater than the length of the existing conventional pin shaft sleeve 6. The platform 72 has the characteristic of being reusable, and the platform 72 can support the installation of various split ball hinges with different tonnages.

[0043] By lengthening the conventional pin shaft sleeve 6 and installing the flange fixing device 7 at the upper end of the pin shaft sleeve 6, while the flange fixing device 7 is used to support the driving device 9, it can also provide a certain height support for the folding between the ball hinge body 1 and the ball hinge split part 2, which is beneficial to the splicing and folding of the ball hinge body 1 and the ball hinge split part 2, improves the splicing efficiency of the ball hinge, enhances the flexibility of the ball hinge. At the same time, the setting of the flange 71 is also beneficial to providing effective support for the installation of the platform 72. The detachable setting of the platform 72 greatly reduces the installation cost.

[0044] The driving device 9 includes a wire winding drum 91, a speed reducer 92, and a motor 93. The wire winding drum 91, the speed reducer 92, and the motor 93 are all arranged on the upper side of the platform 72. The right side of the wire winding drum 91 is connected to the motor 93 through the speed reducer 92. The wire winding drum 91 is used to control the movement of the steel wire rope 10 driven by the motor 93. One end of the steel wire rope 10 is wound around the outside of the wire winding drum 91 through the wire passing hole 73 of the platform. The other end of the steel wire rope 10 is respectively connected to the first wire pulling hole 51 of the left split ball hinge 21 and the second wire pulling hole 52 of the right split ball hinge 22. When the steel wire rope 10 is driven by the motor 93 to retract or lower, the end of the steel wire rope 10 connected to the first wire pulling hole 51 can slide through the first pulley 81, and the end of the steel wire rope 10 connected to the second wire pulling hole 52 can slide through the connected end.

[0045] Through the setting of the driving device 9, installation can be achieved without on-site adjustment, greatly reducing the installation difficulty of the on-site split ball hinge, improving the assembly quality. After the ball hinge is installed, the platform 72 can be removed and reused, and the platform 72 can match various split ball hinge support devices with different tonnages, greatly reducing the installation and use costs of the split ball hinge.

[0046] Specifically, when the motor 93 is powered on, the motor 93 rotating forward increases the torque through the deceleration of the speed reducer 92, drives the wire winding drum 91 to rotate, and the wire winding drum 91 drives the steel wire rope 10 to retract, thereby enabling the ball hinge split 2 to flip and fold around the ball hinge body 1 through the rotating mechanism 3. When the ball hinge split 2 and the ball hinge body 1 rotate to the required first angle ɑ, the pin shaft holes 311 and the sleeve holes 321 between the ball hinge split 2 and the ball hinge body 1 are automatically aligned. A pin 33 is inserted into the rotating mechanism 3 to fix the ball hinge split 2 folded at the required first angle ɑ between the ball hinge split 2 and the ball hinge body 1. At this time, the ball hinge width is reduced, which is convenient for transportation. However, when the ball hinge is installed on-site, first, the pin 33 is pulled out, and then the motor 93 is reversed. The rotating motor 93 increases the torque through the deceleration of the speed reducer 92, drives the wire winding drum 91 to rotate, and drives the steel wire rope 10 to unwind through the wire winding drum 91. Thereby, the ball hinge split 2 is leveled to the same plane as the ball hinge body 1 around the ball hinge body 1 through the rotating mechanism 3 under the action of gravity. At this time, the center lines of the pin shaft holes 311 and the sleeve holes 321 between the ball hinge split 2 and the ball hinge body 1 are not on the same straight line, and the ball hinge assembly is completed.

[0047] The setting of the driving device 9 can effectively automate the installation of the ball hinge, reduce the use of manpower, improve the installation efficiency, solve the difficulties encountered in the on-site assembly of the split ball hinge, reduce the splicing difficulty, increase the installation speed, reduce the installation and transportation costs, improve the work efficiency of the ball hinge installation and transportation, shorten the installation and transportation period of the ball hinge, greatly improve the on-site installation quality of the ball hinge, and with the driving device 9, the automatic assembly of the ball hinge can be realized. Further, the assembly efficiency of the ball hinge is increased and the use of manpower is reduced.

[0048] In the present invention, for any ball hinge of the support device, it may include the split-type automatic assembly ball hinge structure described in this embodiment. On the basis of the relevant structures and assembly relationships of the rotating mechanism 3 and the ball hinge ring rib 41 provided in this embodiment, the ball hinge of the support device further includes conventional components such as an upper ball hinge, a lower ball hinge, and a non-metallic sliding plate. Since they are all prior arts, no further description will be given here.
