Abstract
Description
Technical Field
[0001] This invention relates to the field of anti-tipping gate technology, and more particularly to an anti-tipping gate. Background Technology
[0002] The outdoor gate structure, as disclosed in Chinese Patent Publication No. CN102061880A, consists of a pivot and a bushing. A pivot is installed at the top and bottom of one side of the gate, connected to the gate itself. The pivot is placed within the bushing, which is positioned above the pivot and connected to the wall. This discloses a typical gate structure. However, existing nuclear power plants or large coastal factories typically have gates that are 2 or 3 meters long and wide, and weigh over a ton. Due to the salt spray and sea breezes along the coast accelerating corrosion at the hinge points between the gate and the wall, long-term use of such gates carries a risk of tipping over. Given their large size and weight, tipping over could easily cause injury or death. Summary of the Invention
[0003] Therefore, in response to the above problems, this invention proposes an anti-tipping gate, which solves the technical problems of traditional gates being large in size and weight, and easily causing casualties when they tip over due to corrosion at the hinge joint between the gate and the wall.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: an anti-tipping gate, comprising a gate body and multiple anti-tipping devices disposed on the front and rear sides of the gate body. Each anti-tipping device includes a support rod, connecting parts disposed on the upper and lower sides of the support rod, a hinge seat disposed at the bottom of the support rod, and a mounting frame rotatably connected to the hinge seat. The connecting parts are connected to the gate body. The mounting frame includes a long rod, a shell connected to the long rod, a first reinforcing rod connected to the shell and the support rod, a first support plate disposed at the bottom of the shell, a hinge block disposed on the bottom surface of the first support plate, a second support plate rotatably disposed at the bottom of the hinge block, two first springs disposed between the first and second support plates, and a universal wheel rotatably disposed at the bottom of the second support plate. The two first springs are respectively disposed on the lateral sides of the second support plate. The side of the long rod away from the shell is rotatably connected to the hinge seat. The hinge seat is provided with an orienter for fixing the long rod.
[0005] Furthermore, a second reinforcing rod is provided between the outer shell and the middle of the support rod.
[0006] Furthermore, the orienter includes a first hand-tightening bolt and a second hand-tightening bolt, and the hinge is placed on the upper and lower end faces of the long rod. Both the first hand-tightening bolt and the second hand-tightening bolt are connected to the hinge.
[0007] Furthermore, the outer side of the first hand-tightening bolt is a ring, and the ring has an internal hexagonal hole in the middle.
[0008] Furthermore, the angle between the first reinforcing rod and the long rod is 20-45°, and the angle between the second reinforcing rod and the long rod is 60-70°.
[0009] Furthermore, the connecting part includes a first recessed frame fixedly connected to the support rod and a second recessed frame bolted to the first recessed frame.
[0010] Furthermore, the outer casing is provided with a guide frame, the top of the outer casing is provided with a blocking block, the bottom of the guide frame is provided with a horizontal plate, a vertical plate is slidably connected inside the guide frame, the horizontal plate is provided with an opening for the vertical plate to be inserted at the guide frame, a second spring is provided between the first support plate and the blocking block, the horizontal plate is provided with a through hole for the second spring to pass through, and the first support plate is located at the bottom of the vertical plate.
[0011] Furthermore, the first support plate has an upwardly protruding plate located at the second spring.
[0012] Furthermore, the top of the outer casing is provided with an adjusting bolt for adjusting the elasticity of the second spring, the bottom of the adjusting bolt is provided with a limiting frame to restrict the movement of the second spring outward, the outer side of the adjusting bolt is threadedly connected to the blocking block, and the top of the adjusting bolt is provided with a protrusion.
[0013] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:
[0014] This anti-tipping gate utilizes an anti-tipping device. Before use, the connecting part of the support rod is fixedly connected to the gate. The guide is used to move the bottom surface of the mounting frame close to the ground. Then, the first reinforcing rod is locked and fixed to the support rod. The universal wheels at the bottom of the second support plate provide auxiliary support for the top shell and conform to the ground slope. In actual use, four or more anti-tipping devices are usually symmetrically installed on the front and back sides of the gate. When the hinge between the gate and the wall corrodes and fails, causing the gate to tip over, the mounting frame will support the gate because of the four or more anti-tipping devices installed on the front and back sides, thus avoiding the danger of the gate tipping over after the hinge between the gate and the wall fails due to corrosion.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0029] refer to Figures 1 to 13 This embodiment provides an anti-tipping gate, including a gate body 100 and a plurality of anti-tipping devices 200 disposed on the front and rear sides of the gate body. Each anti-tipping device 200 includes a support rod 1, a connecting part 2 disposed on the upper and lower sides of the support rod 1, a hinge seat 3 disposed at the bottom of the support rod 1, and a mounting frame 4 rotatably connected to the hinge seat 3. The connecting part 2 is connected to the gate body 100.
[0030] The mounting frame 4 includes a long rod 401, a housing 402 connected to the long rod 401, a first reinforcing rod 403 connected to the housing 402 and the support rod 1, a first support plate 52 located at the bottom of the housing 402, a hinge block 53 located on the bottom surface of the first support plate 52, a second support plate 54 rotatably located at the bottom of the hinge block 53, two first springs 55 located between the first support plate 52 and the second support plate 54, and a universal wheel 56 rotatably located at the bottom of the second support plate 54. The two first springs 55 are respectively located on the lateral sides of the second support plate 54. The side of the long rod 401 away from the housing 402 is rotatably connected to the hinge seat 3. The hinge seat 3 is provided with an orienter 404 for fixing the long rod 401.
[0031] Preferably, a first cylinder 57 is provided on the first support plate 52, and a second cylinder 58 is provided at the bottom of the second support plate 54. The first cylinder 57 and the second cylinder 58 surround the end of the first spring 55. The first cylinder 57 and the second cylinder 58 can limit the displacement of the first spring 55 and prevent the first spring 55 from falling between the first support plate 52 and the second support plate 54.
[0032] Before using the mounting frame 4, the connecting part 2 of the support rod 1 is fixedly connected to the door body 100. The direction of the mounting frame 4 is fixed by the orienter 404. Then, the first reinforcing rod 403 is locked and fixed to the support rod 1. In actual use, four or more anti-tipping devices 200 are usually symmetrically installed on the front and back sides of the door body 100. When the hinge part between the door body 100 and the wall fails due to corrosion and tipes over, the mounting frame 4 will support the door body 100 because there are four or more anti-tipping devices 200 installed on the front and back sides of the door body 100, thus avoiding the danger of the door body 100 tipping over after the hinge part between the door body 100 and the wall fails due to corrosion.
[0033] The orientation device 404 is designed so that the anti-tipping devices on the door 100 are evenly distributed. The anti-tipping devices on the side of the door 100 closest to the wall may affect the opening and closing angle of the door 100. First, the bolts connecting the first reinforcing rod 403 on the anti-tipping device located on the wall side to the outer shell 402 are removed. Then, the orientation device 404 is rotated so that it does not contact the long rod 401. After that, the long rod 401 and the mounting frame 4 can be rotated freely. The mounting frame 4 is rotated to a position parallel and in contact with the door 100. After the mounting frame 4 is parallel to the door 100, the door 100 can be in contact with the wall.
[0034] With the first spring 55 in place, when encountering a sloping surface, the second support plate 54 will tilt to one side to adapt to the slope of the ground. The first spring 55 will press down on both sides of the second support plate 54, so that the universal wheels 56 at the bottom will always be in contact with the ground. During the movement of the outer shell 402, the first spring 55 drives the second support plate 54 to tilt, which can adapt to the sloping terrain and glide.
[0035] The outer casing 402 is provided with a guide frame 52a, and a blocking block 52b is provided at the top of the outer casing 402. A horizontal plate 52c is provided at the bottom of the guide frame 52a. A vertical plate 52d is slidably connected inside the guide frame 52a. The horizontal plate 52c is provided with an opening 52e for inserting the vertical plate 52d at the guide frame 52a. A second spring 52f is provided between the first support plate 52 and the blocking block 52b. A through hole 52g is provided inside the horizontal plate 52c for the second spring 52f to pass through. The first support plate 52 is located at the bottom of the vertical plate 52d.
[0036] With the vertical plate 52d in place, the first support plate 52 at the bottom of the vertical plate 52d is connected to the caster 56 via the hinge block 53. Under the action of the second spring 52f, the vertical plate 52d will be pressed downward by the second spring 52f, and the caster 56 connected to the vertical plate 52d will always be in contact with the ground. The second spring 52f keeps the outer shell 402 providing auxiliary support for the gate, avoiding the caster 56 from being suspended in the air on terrain with a certain height difference, thus preventing it from being unable to support the gate and move, thereby improving the safety during use.
[0037] The first support plate 52 has an upwardly protruding convex plate 52h located at the second spring 52f. The convex plate 52h is triangular in shape and locks the inner ring of the second spring 52f to prevent the second spring 52f from shifting from its position inside the outer shell 402.
[0038] The top of the housing 402 is provided with an adjusting bolt 52i for adjusting the elasticity of the second spring 52f. The bottom of the adjusting bolt 52i is provided with a limiting frame 52j to restrict the second spring 52f from moving outward. The outer side of the adjusting bolt 52i is threadedly connected to the blocking block 52b. The top of the adjusting bolt 52i is provided with a protrusion 52k for cooperating with an external wrench.
[0039] When the distance between the outer casing 402 and the ground is too large, the second spring 52f cannot effectively compress the vertical plate 52d. By using an external wrench to rotate the adjusting bolt 52i, the adjusting bolt 52i moves downward through the blocking block 52b, compressing the second spring 52f. When the distance between the terrain and the outer casing 402 is large, the downward pressure of the second spring 52f can be adjusted by adjusting the adjusting bolt 52i, so that the outer casing 402 always remains in contact with the ground.
[0040] A second reinforcing rod 405 is provided between the outer shell 402 and the middle of the support rod 1. The connection hole between the first reinforcing rod 403 and the outer shell 402 is a straight groove. The second reinforcing rod 405, the outer shell 402, the long rod 401 and the support rod 1 form a stable triangular support. The straight groove can adjust the connection angle between the second reinforcing rod 405 and the outer shell 402.
[0041] The first reinforcing rod 403 is connected to the bottom of the support rod 1, and the second reinforcing rod 405 is connected to the middle of the support rod 1. It can effectively support the support rod 1 and has a triangular shape, which provides high support strength and stability.
[0042] The orienter 404 includes a first hand-tightened bolt 04a and a second hand-tightened bolt 04b. The hinge 3 is placed on the upper and lower end faces of the long rod 401. Both the first hand-tightened bolt 04a and the second hand-tightened bolt 04b are connected to the hinge 3. The first hand-tightened bolt 04a and the second hand-tightened bolt 04b are arranged alternately on the left and right sides. They can also be replaced with existing standard bolts. The orienter 404 is located on the left and right sides of the hinge 3. After being tightened toward the long rod 401, the orienter 404 provides a better fixation effect for the long rod 401, preventing the mounting frame 4 from rotating. At the same time, it reduces the limiting support of the first reinforcing rod 403 and the second reinforcing rod 405 on the mounting frame 4.
[0043] The first hand-tightening bolt 04a preferably has an outer ring 4a, and the ring 4a has an internal hexagonal hole 4b in the middle for easy and quick rotation by hand. The second hand-tightening bolt 04b has the same structure as the first hand-tightening bolt 04a.
[0044] When in use, if the mounting frame 4 is close to the wall, it is necessary to rotate the mounting frame 4 90° frequently when opening and closing the door. When the orienter 404 is the first hand-tightening bolt 04a and the second hand-tightening bolt 04b, it can be used quickly without the aid of external tools, which makes it convenient for users to quickly rotate the anti-tipping device. The bolts at the connection positions of the first reinforcing rod 403 and the outer shell 402 and the second reinforcing rod 405 and the outer shell 402 can also be of the same structure, which can realize the quick assembly and disassembly of the first reinforcing rod 403 and the second reinforcing rod 405.
[0045] The angle between the first reinforcing rod 403 and the long rod 401 is 20-45°, preferably 38°. The angle between the second reinforcing rod 405 and the long rod 401 is 60-70°. At this angle, the connection and support with the support rod 1 can be strengthened, and the long rod 401 can be kept parallel to the ground. It provides auxiliary support for the long rod 401 and the outer shell 402, avoiding the problem of the outer shell 402 being easily deformed due to concentrated force on one side. In addition, the first reinforcing rod 403 increases the impact resistance of the bottom of the support rod 1, and the second reinforcing rod 405 increases the impact resistance of the top of the support rod 1. When the door hinge is corroded and broken, it can provide stable support for the door.
[0046] The connecting part 2 includes a first recessed frame 201 fixedly connected to the support rod 1, and a second recessed frame 202 bolted to the first recessed frame 201. When there is a first recessed frame 201 and a second recessed frame 202, the adjustment can be made by adjusting the bolts between the first recessed frame 201 and the second recessed frame 202. Alternatively, the connecting part 2 may not have a first recessed frame 201 and a second recessed frame 202, and the upper and lower sides of the support rod 1 can be directly welded and fixed to the door.
[0047] The second support plate 54 is provided with a fastening assembly for locking the caster wheel 56. The second support plate 54 has a stepped groove 1e at the fastening assembly. The fastening assembly includes a washer 1f located at the stepped groove 1e, a fastening nut 1g located at the bottom of the washer 1f, and a fastening bolt 1h for connecting with the fastening nut 1g. The outer side of the washer 1f has multiple spaced first ratchet plates 1i. The first ratchet plates 1i are inclined from top to bottom and from right to left, with an inclination angle of 35° to 45°. The top surface of the fastening nut 1g is provided with a plurality of spaced raised textures 1j. The outer side of the washer 1f is provided with a second ratchet 1k between the first ratchet 1i. The distance from the bottom of the first ratchet 1i to the outer side of the washer 1f is greater than the distance from the bottom of the second ratchet 1k to the outer side of the washer 1f. The bottom of the first ratchet 1i is located on the side of the fastening nut 1g. The bottom of the second ratchet 1k is located on the raised textures 1j on the top surface of the fastening nut 1g. The stepped groove 1e is provided at the washer 1f with a protruding ridge 1L for engaging between the first ratchet 1i and the second ratchet 1k.
[0048] The first ratchet 1i and the second ratchet 1k have a certain degree of toughness. When the fastening bolt 1h and the fastening nut 1g are tightened, bending and elastic forces are generated. The inclination angle of each of the first ratchet 1i and the second ratchet 1k on the outer side of the washer 1f is greater than the pitch of the fastening bolt 1h and the fastening nut 1g, so that the fastening bolt 1h and the fastening nut 1g are tightly attached to the second connecting piece 1c.
[0049] To set up the fastening assembly, first place the shim 1f into the stepped groove 1e, then rotate the shim 1f so that the first ratchet 1i and the second ratchet 1k on the outside engage with the protrusion 1L of the stepped groove 1e. At this time, the position of the shim 1f will be restricted and will not rotate, which can prevent vibration during use. When the fastening nut 1g and the shim 1f rotate, the top of the rotating first ratchet 1i and the second ratchet 1k will wear on the inner side of the stepped groove 1e, causing the connection between the shim 1f and the stepped groove 1e to loosen easily.
[0050] After installation, insert the bottom of the washer 1f into the fastening nut 1g, and align the middle of the six outer edges of the fastening bolt 1h with the bottom of the first ratchet 1i. Then, insert the fastening bolt 1h from the top of the second connecting piece 1c and tighten it. After tightening, the fastening nut 1g will push the washer 1f upwards, and the first ratchet 1i will twist and tightly engage with the six outer edges of the fastening bolt 1h. At the same time, the second ratchet 1k at the top of the fastening nut 1g will engage with the raised groove 1j on the top surface of the fastening nut 1g. When vibration occurs and the fastening bolt 1h rotates, the second ratchet 1k of the washer 1f will contact the raised groove 1j on the top surface of the fastening nut 1g, preventing the fastening nut 1g from rotating in the opposite direction. Meanwhile, the first ratchet 1i on the outer side will hold the fastening nut 1g in place, thus preventing the second connecting piece 1c from easily vibrating due to the influence of the first spring, the second spring, and road bumps, which could cause the fastening bolt 1h to loosen.
[0051] The fastening nut 1g is provided with a rubber ring 1o on the outside of the fastening nut 1g near the washer 1f. When the fastening bolt is tightened, the first ratchet contacts the rubber ring, which can eliminate the gap between the first ratchet and the outside of the fastening nut, making the first ratchet fit more tightly with the fastening nut. In addition, some fastening nuts have anti-corrosion requirements, especially for doors used in coastal areas. The outside of the fastening nut has anti-corrosion paint. If the first ratchet directly contacts the fastening nut, it will scratch off the anti-corrosion paint on the outside of the fastening nut. The rubber ring can also protect the anti-corrosion paint on the outside of the fastening nut.
