Description

Technical Field

[0001] This utility model relates to the field of traffic connection equipment technology, specifically to prefabricated load-bearing engineering maintenance traffic connection equipment. Background Technology

[0002] Traffic connection equipment for infrastructure maintenance is a temporary structure that is quickly assembled from prefabricated components. Its main function is to provide safe and reliable temporary passage for vehicles and heavy equipment across work areas, structural joints or underground excavation sections during the construction or maintenance of infrastructure such as roads and bridges. It can effectively reduce the interference of the project on existing traffic and ensure maintenance efficiency and traffic safety.

[0003] In the maintenance of roads and bridges, traffic connection equipment is often used to provide temporary passage for vehicles. Although traffic connection equipment has basic road connection functions, most of them are one-piece structures. One-piece structures require on-site formwork and pouring, which can lead to long-term road closures and serious traffic disruptions. This cannot meet the needs of rapid emergency response and minimal disruption. At the same time, one-piece structures lack flexibility and repeatability. Therefore, improvements are needed. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide prefabricated load-bearing engineering maintenance traffic connection equipment, which solves the technical problems of lack of flexibility and repeatability in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a prefabricated load-bearing engineering maintenance traffic connection device, including a mounting plate. Connecting blocks are fixedly connected to the front and rear sides of the right side of the mounting plate. A spline shaft is movably sleeved inside the connecting block. The inner side of the spline shaft passes through the connecting block and extends to the outside of the connecting block, and is movably sleeved with a movable block. A traffic connection frame is movably connected to the outer surface of the movable block. Threaded rods are movably sleeved on both the front and back sides of the traffic connection frame. The other end of the threaded rod passes through the traffic connection frame and extends into the inner cavity of the traffic connection frame, and is threadedly sleeved with the inner surface of the movable block. A limit rod is fixedly installed in the inner cavity of the traffic connection frame, and the outer surface of the limit rod is movably sleeved with the inner surface of the movable block.

[0006] The threaded rod has a self-locking function. When the threaded rod is rotated, the movable block will move away from the connecting block along the inner surface of the traffic connecting frame under the limiting action of the limiting rod. When the movable block moves to the limit of its stroke, it will disengage from the outer surface of the spline shaft. Finally, after both movable blocks disengage from the outer surface of the spline shaft, the fixing effect on the traffic connecting frame will be released.

[0007] For example, in at least one embodiment of the prefabricated load-bearing engineering maintenance traffic connection equipment provided in this disclosure, countersunk holes are provided at the four corners of the top of the mounting plate, and the number of countersunk holes is four, and the four countersunk holes are all the same size.

[0008] This design prevents the nuts from protruding above the mounting plate during bolt fixing, thus avoiding damage to the tires of cars traveling on the mounting plate.

[0009] For example, in at least one embodiment of the present disclosure, a prefabricated load-bearing engineering maintenance traffic connection device is provided, wherein an inclined groove is provided on the left side of the mounting plate, and the outer surface of the inclined groove is smooth.

[0010] This design allows cars to drive onto the mounting plate more easily, reducing the swaying of the car while driving on the mounting plate and improving driver comfort.

[0011] For example, in at least one embodiment of the present disclosure, a prefabricated load-bearing engineering maintenance traffic connection device is provided, wherein the bottom of the mounting plate is fixedly connected to a support foundation, the top of the support foundation is provided with a maintenance area, and the top of the support foundation is movably connected to the bottom of the traffic connection frame.

[0012] When the traffic connection frame is rotated to a horizontal position, it will be erected on the area to be maintained, ensuring the safe passage of vehicles and equipment through the construction area and forming a temporary traffic access road.

[0013] For example, in at least one embodiment of the present disclosure, a prefabricated load-bearing engineering maintenance traffic connection device is provided, wherein a handle is movably sleeved at the bottom of the traffic connection frame, the top of the handle penetrates through the traffic connection frame and extends into the inner cavity of the traffic connection frame and is fixedly sleeved with an eccentric rod, and a sleeve rod is movably connected to the outer surface of the eccentric rod.

[0014] When the handle is rotated, the eccentric rod will rotate synchronously, and at this time the eccentric rod will squeeze and push the sleeve rod.

[0015] For example, in at least one embodiment of the present disclosure, a prefabricated load-bearing engineering maintenance traffic connection device is provided, wherein a connecting rod is fixedly connected to the right side of the sleeve rod, and a telescopic plate is fixedly connected to the other end of the connecting rod, and the outer surface of the telescopic plate is movably connected to the inner surface of the traffic connection frame.

[0016] When the eccentric rod presses against the sleeve rod, the sleeve rod will cause the connecting rod and the telescopic plate to extend from the inside of the traffic connection frame to the outside under the limiting action of the traffic connection frame.

[0017] For example, in at least one embodiment of this disclosure, a prefabricated load-bearing engineering maintenance traffic connection device is provided, wherein a fixed rod is fixedly connected to the inner cavity of the traffic connection frame, and the right end of the fixed rod is movably sleeved with the inner surface of the telescopic plate.

[0018] Due to the limiting effect of the fixed rod, the telescopic plate can only move horizontally.

[0019] For example, at least one embodiment of the present disclosure provides a prefabricated load-bearing engineering maintenance traffic connection device, wherein a rectangular block is fixedly connected to the front of the traffic connection frame, a tie rod is movably sleeved on the inner surface of the rectangular block, and the other end of the tie rod passes through the rectangular block and extends to the outside of the rectangular block and is fixedly connected to a locking block.

[0020] When the lever is pulled, the locking block will move horizontally to the right under the limiting action of the rectangular block.

[0021] For example, in at least one embodiment of the present disclosure, a prefabricated load-bearing engineering maintenance traffic connection device is provided, wherein a gear is engaged with the left side of the locking block, the inner surface of the gear is fixedly sleeved with the outer surface of the threaded rod, and the gear is made of stainless steel.

[0022] Once the locking block disengages from the outer surface of the gear, it will release the gear and threaded rod from their fixing effect.

[0023] For example, in at least one embodiment of the present disclosure, a prefabricated load-bearing engineering maintenance traffic connection device is provided, wherein a stainless steel spring is movably sleeved on the outer surface of the pull rod, the left end of the stainless steel spring is fixedly connected to the right side of the locking block, and the right side of the stainless steel spring is fixedly connected to the left side of the rectangular block.

[0024] Due to the elastic force of the stainless steel spring, the locking block has a good reset effect in subsequent movements.

[0025] The beneficial effects of this utility model are as follows: This invention utilizes a splined shaft, movable blocks, a traffic connecting frame, a threaded rod, and a limiting rod. First, pulling the lever causes the locking block to overcome the elastic force of the stainless steel spring, move to the right, and disengage from the outer surface of the gear. This releases the fixing effect on the gear and the threaded rod. Then, rotating the threaded rod causes the movable block, limited by the limiting rod, to move along the inner surface of the traffic connecting frame away from the connecting block. When the movable block reaches its travel limit, it disengages from the outer surface of the splined shaft. Finally, after both movable blocks disengage from the outer surface of the splined shaft, the fixing effect on the traffic connecting frame is released. This design facilitates the disassembly and assembly of the mounting plate and traffic connecting frame, allowing for rapid on-site assembly of prefabricated components. This meets the requirements for rapid emergency response and minimal disruption, while also offering greater flexibility and repeatability compared to integrated designs. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0029] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0030] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] like Figures 1-5 As shown, this invention illustrates a prefabricated load-bearing engineering maintenance traffic connection device according to an embodiment of the present invention, including a mounting plate 1. Connecting blocks 2 are fixedly connected to the front and rear sides of the right side of the mounting plate 1. A spline shaft 3 is movably sleeved inside the connecting block 2. The inner side of the spline shaft 3 passes through the connecting block 2 and extends to the outside of the connecting block 2, and is movably sleeved with a movable block 4. A traffic connection frame 5 is movably connected to the outer surface of the movable block 4. Threaded rods 6 are movably sleeved on both the front and back sides of the traffic connection frame 5. The other end of the threaded rod 6 passes through the traffic connection frame 5 and extends into the inner cavity of the traffic connection frame 5, and is threadedly sleeved with the inner surface of the movable block 4. A limiting rod 7 is fixedly installed in the inner cavity of the traffic connection frame 5, and the outer surface of the limiting rod 7 is movably sleeved with the inner surface of the movable block 4.

[0035] The threaded rod 6 has a self-locking function. When the threaded rod 6 is rotated, the movable block 4 will move away from the connecting block 2 along the inner surface of the traffic connecting frame 5 under the limiting action of the limiting rod 7. When the movable block 4 moves to the limit of its stroke, it will disengage from the outer surface of the spline shaft 3. Finally, after both movable blocks 4 disengage from the outer surface of the spline shaft 3, the fixing effect on the traffic connecting frame 5 will be released.

[0036] In some examples, the prefabricated load-bearing engineering maintenance traffic connection equipment has countersunk holes 8 at the four corners of the top of the mounting plate 1. There are four countersunk holes 8, and the four countersunk holes 8 are all the same size.

[0037] This design prevents the nuts from protruding above the mounting plate 1 during the bolt fixing process, thus avoiding damage to the tires of the car traveling on the mounting plate 1.

[0038] In some examples, the prefabricated load-bearing engineering maintenance traffic connection equipment has a sloping groove 9 on the left side of the mounting plate 1, and the outer surface of the sloping groove 9 is smooth.

[0039] This design allows the car to drive onto the mounting plate 1 more easily, reducing the shaking of the car while driving on the mounting plate 1 and improving the driver's comfort.

[0040] In some examples, the prefabricated load-bearing engineering maintenance traffic connection equipment has a support base 10 fixedly connected to the bottom of the mounting plate 1, a maintenance area 11 opened on the top of the support base 10, and the top of the support base 10 is movably connected to the bottom of the traffic connection frame 5.

[0041] When the traffic connection frame 5 is rotated to a horizontal position, it will be erected on the maintenance area 11 to ensure the safe passage of vehicles and equipment through the construction area and to form a temporary traffic access road.

[0042] In some examples, the prefabricated load-bearing engineering maintenance traffic connection equipment has a handle 12 movably sleeved at the bottom of the traffic connection frame 5, the top of the handle 12 penetrating through the traffic connection frame 5 and extending into the inner cavity of the traffic connection frame 5 and fixedly sleeved with an eccentric rod 13, and a sleeve rod 14 movably connected to the outer surface of the eccentric rod 13.

[0043] When the handle 12 is rotated, the eccentric rod 13 will rotate synchronously, and the eccentric rod 13 will squeeze and push the sleeve rod 14.

[0044] In some examples, in the prefabricated load-bearing engineering maintenance traffic connection equipment, the right side of the sleeve rod 14 is fixedly connected to the connecting rod 15, and the other end of the connecting rod 15 is fixedly connected to the telescopic plate 16. The outer surface of the telescopic plate 16 is movably connected to the inner surface of the traffic connection frame 5.

[0045] When the eccentric rod 13 presses against the sleeve rod 14, the sleeve rod 14 will cause the connecting rod 15 and the telescopic plate 16 to extend outward from the inside of the traffic connection frame 5 under the limiting action of the traffic connection frame 5.

[0046] In some examples, the prefabricated load-bearing engineering maintenance traffic connection equipment has a fixed rod 17 fixedly connected to the inner cavity of the traffic connection frame 5, and the right end of the fixed rod 17 is movably sleeved with the inner surface of the telescopic plate 16.

[0047] Due to the limiting effect of the fixed rod 17, the telescopic plate 16 can only move horizontally.

[0048] In some examples, the prefabricated load-bearing engineering maintenance traffic connection equipment has a rectangular block 18 fixedly connected to the front of the traffic connection frame 5. A tie rod 19 is movably sleeved on the inner surface of the rectangular block 18. The other end of the tie rod 19 passes through the rectangular block 18 and extends to the outside of the rectangular block 18 and is fixedly connected to a locking block 20.

[0049] When the lever 19 is pulled, the locking block 20 will move horizontally to the right under the limiting action of the rectangular block 18.

[0050] In some examples, the prefabricated load-bearing engineering maintenance traffic connection equipment has a gear 21 engaged on the left side of the locking block 20. The inner surface of the gear 21 is fixedly sleeved with the outer surface of the threaded rod 6. The gear 21 is made of stainless steel.

[0051] Once the locking block 20 disengages from the outer surface of the gear 21, it will release the fixing effect on the gear 21 and the threaded rod 6.

[0052] In some examples, in the prefabricated load-bearing engineering maintenance traffic connection equipment, the outer surface of the tie rod 19 is movably sleeved with a stainless steel spring 22, the left end of the stainless steel spring 22 is fixedly connected to the right side of the locking block 20, and the right side of the stainless steel spring 22 is fixedly connected to the left side of the rectangular block 18.

[0053] Due to the elastic force of the stainless steel spring 22, the locking block 20 has a good reset effect in subsequent movements.

[0054] Working principle and usage process of this utility model: First, the mounting plate 1 is fixed to the designated position on the support base 10 through four countersunk holes 8 on the top of the mounting plate 1. Then, the movable block 4 is moved to the end of the threaded rod 6 in advance, and the through hole on the movable block 4 is aligned with the spline shaft 3. Then, the pull rod 19 is pulled, so that the locking block 20 overcomes the elastic force of the stainless steel spring 22, moves to the right and disengages from the outer surface of the gear 21. At this time, the fixing effect on the gear 21 and the threaded rod 6 is released. Then, the threaded rod 6 is rotated, so that the movable block 4 moves towards the connecting block 2 along the inner surface of the traffic connecting frame 5 under the limiting action of the limiting rod 7. When the movable block 4 moves to the limit of its stroke, the spline shaft 3 will be inserted into the interior of the movable block 4, and the fixing effect on the movable block 4 and the traffic connecting frame 5 will be achieved. In this way, the device can be quickly assembled on site with prefabricated components, thereby meeting the needs of rapid emergency and minimal interference. At the same time, it is more flexible and repeatable than the integrated type.

[0055] When the area to be maintained 11 is large, in order to adapt to changes in length, the traffic connecting frame 5 is rotated and lifted, and the handle 12 is rotated, so that the handle 12 drives the eccentric rod 13 to rotate synchronously. This causes the eccentric rod 13 to squeeze and push the inner wall of the sleeve rod 14, and the sleeve rod 14 to drive the connecting rod 15 to move to the right. At this time, under the limiting and guiding action of the fixed rod 17, the telescopic plate 16 will extend outward along the inner surface of the traffic connecting frame 5, thereby increasing the overall length of the traffic connecting frame 5 and the telescopic plate 16. This allows the device to adapt to various sizes of the area to be maintained 11 in actual road conditions, improving the flexibility and applicability of the device.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
