[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The invention discloses an adjustable supporting frame for a corridor bridge body, which is set up under the corridor bridge body and plays a supporting role when the corridor is hoisted and unloaded.

[0028] Reference Figure 1 , Figure 2 and Figure 3The support frame 1 includes a bottom rectangular support frame 112, a connecting platform 108 installed above the rectangular support frame 112, and a triangular support frame 102 installed above the connecting platform 108, wherein guardrails 106 are installed around the top of the connecting platform 108, and connecting sleeves 101 are installed at the four corners of the top of the connecting platform 108 and on the inner side of the guardrails 106. A matching lifting control device 107 and a load monitoring device 111 are arranged inside the connecting sleeve 101. The lifting control device 107 is essentially a jack used to control the lifting and return of the bridge deck section, and the load monitoring device 111 is essentially a pressure sensor, which is used to monitor the bearing capacity of the bridge deck section and the supporting frame; a triangular support frame 102 is installed on the top of the four connecting sleeves 101, and the triangular support frame 102 is composed of an inclined rod 105, a pneumatic lifting rod 103 and a common rod. The pneumatic lifting rod 103 includes a lifting column rod 1031 and a circular perforated connecting rod 1032 arranged on the top of the lifting column rod 1031. It should be noted that the pneumatic lifting rod 103 is only used to control the lifting at the beginning. In order to adapt to bridge decks at different angles, it is fixed after the bridge deck is fixed. After that, the lifting and return of the bridge deck are controlled by the lifting control device 107;

[0029] Two inclined rods 105 are installed on one side of the top of the gas pressure lifting rod 103, wherein the tops of the two inclined rods 105 are connected to the core rod positioning holes of the annular perforated connecting rod 1032 at the top of the gas pressure lifting rod 103, and the bottoms are hinged to the other side of the top of the triangular support frame 102. The inclined rods 105, the gas pressure lifting rods 103 and the ordinary rods form a triangular structure with strong stability. The angle and height of the inclined rods 105 can be adjusted by the gas pressure lifting rods 103 to adapt to the bridge deck section, and the clamping devices 104 for clamping the bridge deck section are installed on the two inclined rods 105;

[0030] Furthermore, the clamping device 104 includes a supporting and fixing rod 1042, wherein arc-shaped clamping rods 1041 are detachably mounted on both sides of the top of the supporting and fixing rod 1042, and the supporting and fixing rod 1042 includes two symmetrically arranged connecting rods, which are detachably connected by a pin or a bolt, and the distance between the two connecting rods can be adjusted by adjusting the distance between the two connecting rods, thereby adjusting the distance between the two arc-shaped clamping rods 1041 to adapt to the corresponding bridge deck section;

[0031] It should be noted that, refer to Figure 4 A groove with a convex structure is opened inside the inclined rod 105, and a core rod 110 with a convex structure is installed inside the groove. One end of the core rod 110 is connected to the core rod positioning hole reserved in the annular perforated connecting rod 1032 at the top of the pneumatic lifting rod 103.

[0032] The supporting tire frame 1 is provided with a pneumatic lifting rod 103 above the bottom support frame and the connecting platform 108. While ensuring stable support of the structure, it can also be used for support adjustment of the bridge deck structure under different heights and angles. It has strong adaptability and a wide range of uses, greatly reduces waste of resources, and prevents instability caused by the bridge deck structure along the inclined support. It is highly practical, and the present application can be reused, with good economic benefits.

[0033] A ball joint is used to connect the core rod 110 in the inclined rod 105 and the core rod positioning hole at the top of the pneumatic lifting rod 103, which can adapt to connections at different heights and angles and facilitate the adjustment of height and angle. In this application, a triangular structure can be formed between the inclined rod 105, the pneumatic lifting rod 103 and the ordinary rod. The four corners of the triangular support frame are provided with connecting sleeves that match the jacking control device 107 to ensure uniform jacking distribution and stable structural support.

[0034] The working principle of the adjustable support frame for the corridor bridge body of this application is as follows:

[0035] When the corridor bridge body is installed and unloaded, the support frame 1 is erected under the corridor bridge body. When erecting and installing, the support frame 1 needs to be adjusted according to the size of the corridor bridge body itself, that is, the angle and height of the inclined rod 105 are controlled by the pneumatic lifting rod 103. One end of the inclined rod 105 is ball-jointedly connected to the core rod positioning hole at the top of the pneumatic lifting rod 103, and the other end of the inclined rod 105 is rotatably connected to the ordinary rod. Such a connection will not limit the adjustment of the angle of the inclined rod 105. Therefore, the angle of the inclined rod 105 can be adjusted according to the pneumatic lifting rod 103, and the clamping device 104 installed on the inclined rod 105 is also adjusted accordingly until it can be connected and fixed to the corridor bridge body to support the corridor bridge body; and then the jacking and return of the bridge deck are controlled by the jacking control device 107 to perform the overall jacking or lowering.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
