Description

Technical Field

[0001] The utility model relates to the technical field of load-bearing bent frames, in particular to a Bailey truss type load-bearing bent frame capable of rapid docking. Background Technique

[0002] The Bailey truss type load-bearing bent frame is an assembled steel structure bridge, a steel frame composed of certain units, which can be spliced into required components or equipment. In engineering construction, the Bailey truss is widely used in the support structures of bridge projects, tunnel projects and high-rise buildings. It can not only be used as the support of engineering beams, engineering plates, temporary supports, etc., but also can cope with various construction environments and construction difficulties. However, the existing Bailey truss type load-bearing bent frames still have some defects and deficiencies that need to be improved in some aspects:

[0003] For example, a Bailey truss structure with the application number: CN202220826573.X, which relates to the field of building workpieces. The Bailey truss structure includes: a Bailey truss main body, a connecting seat and a telescopic rod. The Bailey truss main body includes upper and lower chord rods, and wing plates are arranged at the top and bottom of the upper and lower chord rods; the connecting seats are arranged in pairs and are respectively arranged on the upper and lower chord rods. The connecting seat includes a first supporting part abutting against the wing plate at the bottom of the upper chord rod or the wing plate at the top of the lower chord rod, and a second supporting part abutting against the wing plate at the top of the upper chord rod or the wing plate at the bottom of the lower chord rod; both ends of the telescopic rod are respectively hinged to the connecting seats on the upper and lower chord rods, and are used to support the non-node and weak node positions of the Bailey truss. Compared with the existing Bailey truss structure acting on a single wing plate, the wing plate of this Bailey truss structure is not easy to deform and break, the structure is more stable, and it can better improve the structural strength of the non-node and weak node positions of the Bailey truss. It can be adjusted and installed in multiple positions and reused; at the same time, the side hinge ears of adjacent connecting seats are connected by a telescopic rod, so that each connecting seat and the telescopic rod are connected to form a whole, improving the overall structural strength.

[0004] For the Bailey truss type load-bearing bent frame in the above document, when installing the Bailey truss plates, there may be a phenomenon of jamming between the Bailey truss plates and the docking grooves. At this time, manual movement is still required to make the Bailey truss plates better dock into the inside of the card slots, and the operation is relatively cumbersome;

[0005] For the Bailey truss type load-bearing bent frame in the above document, after the Bailey truss plates are installed and fixed, there is no secondary limit for them, so that the Bailey truss plates may be loose or even fall off.

[0006] Therefore, we propose a Bailey truss type load-bearing bent frame capable of rapid docking to facilitate solving the above-mentioned problems. Content of the Utility Model

[0007] The purpose of the present utility model is to provide a Bailey truss type load-bearing bent which can be quickly docked, so as to solve the problems that there may be a jamming phenomenon between the Bailey plates and the docking grooves, and after the Bailey plates are installed and fixed, there is no secondary limit for them, thus making it possible for the Bailey plates to be loose or even fall off as mentioned in the above background technology.

[0008] To achieve the above purpose, the present utility model provides the following technical solution: A Bailey truss type load-bearing bent which can be quickly docked, including an installation base, a docking groove is opened inside the installation base, and a Bailey plate is nested and clamped in the docking groove

[0009] An activity groove, the activity groove is opened inside the installation base, and an auxiliary rod is fixedly connected inside the activity groove, and an auxiliary plate is nested and connected to the outside of the auxiliary rod, and at the same time, a knocking plate is fixedly connected to the outer end of the auxiliary plate, and a reciprocating mechanism for knocking the installation base is arranged between the knocking plate and the activity groove;

[0011] Further, the reciprocating mechanism includes a ball, the ball is nested and connected to the inner side of the installation base, and a fixed shaft is fixedly connected to the lower end of the ball, and a connecting roller is fixedly connected to the lower end of the fixed shaft, and at the same time, the fixed shaft is nested and connected inside the activity groove, and a convex block is fixedly connected to the outside of the connecting roller.

[0012] Further, the outer surface of the ball is in contact with the outer side of the lower end of the Bailey plate, and the ball and the connecting roller form an integrated structure through the fixed shaft.

[0013] Further, the knocking plate is located directly in front of the connecting roller, and the knocking plate is "C"-shaped in a top view, and four convex blocks are arranged in a circular array around the center point of the connecting roller.

[0014] Further, the buffer mechanism includes a chute, the chute is opened on the front side of the driving plate, and a limiting rod is fixedly connected inside the chute, and a slider is nested and connected to the outside of the limiting rod;

[0015] A first spring is fixedly connected between the slider and the chute, and a rotating rod is hinged to the outer end of the slider, and a fixing plate is hinged to the outer end of the rotating rod.

[0016] Further, the slider forms a rotating structure with the chute through the first spring, and two groups of sliders are vertically symmetrically arranged about the center point of the limiting rod.

[0017] Furthermore, the slider forms a sliding structure with the limiting rod through a rotating rod, and the rotating rod forms a rotating structure with the slider through a fixing plate.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1. The user can initially dock and install the Bailey truss through the docking groove opened on the mounting base. When the Bailey truss is slidably installed inside the docking groove, the balls will roll synchronously under the drive of the Bailey truss. At this time, under the action of the balls, the Bailey truss can be installed more conveniently during sliding installation;

[0020] 2. While the balls are rolling, they will synchronously drive the connecting roller to rotate, and reciprocally contact the knocking plate through the convex block.

[0022] 4. After the Bailey truss is installed, the user can manually rotate the handle, and drive the threaded rod through this handle. At this time, the threaded rod will synchronously drive the driving plate to move, and drive the fixing plate to move through the driving plate, thereby clamping and fixing the Bailey truss through the fixing plate;

[0023] 5. When the fixing plate contacts the Bailey truss, the extrusion force will synchronously drive the fixing plate to move towards the side of the driving plate. At this time, the fixing plate will cause the rotating rod to rotate, and synchronously push the slider through the rotating rod. At this time, the slider will compress the first spring, and the first spring will buffer the slider under the drive of its own elastic force, thereby further buffering the movement of the fixing plate and realizing stable clamping of the Bailey truss.

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Embodiment 1: As Figure 1 and Figure 3 shown in the technical solution, the present utility model provides the following technical solution: A Bailey truss type load-bearing bent that can be quickly docked, discloses a docking groove 3, and the Bailey truss 1 can be preliminarily docked through the docking groove 3:

[0035] A mounting base 2, a docking groove 3 is opened inside the mounting base 2, and a Bailey truss 1 is nested and engaged in the docking groove 3;

[0036] The user can perform preliminary docking and installation of the Bailey truss 1 through the docking groove 3 opened on the mounting base 2. When the Bailey truss 1 is slidably installed inside the docking groove 3, the balls 14 will roll synchronously under the drive of the Bailey truss 1. At this time, under the action of the balls 14, the Bailey truss 1 can be made more convenient during sliding installation. During the movement of the knocking plate 4, the auxiliary plate 19 will be driven to move synchronously outside the auxiliary rod 18. At this time, the auxiliary rod 18 will limit the auxiliary plate 19, thereby further limiting the knocking plate 4 and making the movement of the knocking plate 4 more stable.

[0037] Embodiment 2: As Figure 3 , Figure 7 and Figure 8 shown in the technical solution, the present utility model provides the following technical solution: A Bailey truss type load-bearing bent that can be quickly docked, discloses a reciprocating mechanism, and the installation base 2 can be knocked through the reciprocating mechanism so that the Bailey plate 1 can be better slid and docked:

[0038] The movable groove 20 is opened inside the installation base 2, and an auxiliary rod 18 is fixedly connected inside the movable groove 20. An auxiliary plate 19 is nested on the outer side of the auxiliary rod 18. At the same time, a knocking plate 4 is fixedly connected to the outer end of the auxiliary plate 19. A reciprocating mechanism for knocking the installation base 2 is arranged between the knocking plate 4 and the movable groove 20;

[0039] The reciprocating mechanism includes a ball 14, the ball 14 is nested and connected to the inner side of the installation base 2, and a fixed shaft 15 is fixedly connected to the lower end of the ball 14. A connecting roller 16 is fixedly connected to the lower end of the fixed shaft 15. At the same time, the fixed shaft 15 is nested and connected inside the movable groove 20. A convex block 17 is fixedly connected to the outer side of the connecting roller 16. The outer surface of the ball 14 is in contact with the outer side of the lower end of the Bailey plate 1. The ball 14 and the connecting roller 16 form an integrated structure through the fixed shaft 15. The knocking plate 4 is located directly in front of the connecting roller 16, and the knocking plate 4 is "C"-shaped when viewed from above. Four convex blocks 17 are arranged in a circular array around the center point of the connecting roller 16.

[0040] When the ball 14 rolls, it will synchronously drive the fixed shaft 15 to rotate. At this time, the fixed shaft 15 will drive the connecting roller 16 to rotate. When the connecting roller 16 rotates, it will reciprocally contact the knocking plate 4 through the convex block 17 fixedly connected to the outer side. At this time, the outer side of the knocking plate 4 will reciprocally knock the outer side of the installation base 2 under the action of the contact force, so that the installation base 2 vibrates. The vibrating installation base 2 can, to a certain extent, make the Bailey plate 1 slide better inside the docking groove 3, reducing the occurrence of the Bailey plate 1 being stuck.

[0041] Embodiment 3: As Figure 2 , Figure 4 , Figure 5 and Figure 6 shown in the technical solution, the present utility model provides the following technical solution: A Bailey truss type load-bearing bent that can be quickly docked, discloses a buffer mechanism, and the Bailey plate 1 is buffered and clamped through the buffer mechanism:

The slider 13 forms a sliding structure with the limiting rod 11 through the rotating rod 10, and the rotating rod 10 forms a rotating structure with the fixing plate 8 through the slider 13.

[0045] After the Bailey bridge 1 is installed, the user can manually rotate the handle 5, and drive the threaded rod 6 through the handle 5. At this time, the threaded rod 6 will synchronously drive the driving plate 7 to move, and drive the fixing plate 8 to move through the driving plate 7. When the fixing plate 8 contacts the Bailey bridge 1, the extrusion force will synchronously drive the fixing plate 8 to move towards one side of the driving plate 7. At this time, the fixing plate 8 will cause the rotating rod 10 to rotate, and synchronously push the slider 13 through the rotating rod 10. At this time, the slider 13 will squeeze the first spring 12. The first spring 12 will buffer the slider 13 under the drive of its own elastic force, thereby further buffering the movement of the fixing plate 8 and realizing the stable clamping of the Bailey bridge 1.
