Description

Technical Field

[0001] This invention relates to the field of bridge erection technology and equipment, and in particular to a support base for a bridge erection operation mechanism. Background Technology

[0002] The support structure plays a crucial role in the erection and dismantling of impact bridges. As a fulcrum, it supports the overall weight of the bridge and the erection system, playing a vital role in the erection, maintenance, and dismantling of the bridge. During bridge erection, the design of the support structure must consider various factors, including the bridge's weight, span, terrain conditions, and external forces and vibrations that may be encountered during construction. The support structure needs to be able to stably support the entire bridge structure, ensuring safety and stability during construction. During dismantling, the support structure also plays a vital role. It needs to be able to effectively support the weight of the bridge to ensure that no accidents occur during dismantling and dismantling. Furthermore, the support structure needs to have a certain degree of flexibility to adjust and adapt to the actual conditions during dismantling.

[0003] Regarding the aforementioned technologies, the inventors believe that when erecting short bridges, the support mechanism relies on the strength of its own structure. However, when erecting combined bridges, the longitudinal beams between the extended support and the chassis deck can cause bending deformation of the working rocker arm, leading to dangerous operations. Summary of the Invention

[0004] To reduce rocker arm deformation during operation, ensure stable and reliable bridge erection, and guarantee the driver's visibility, this invention provides a support base for a bridge erection mechanism.

[0005] The present invention provides a support base for a bridge erection mechanism, which adopts the following technical solution:

[0006] A support base for a bridge erection mechanism includes a frame assembly, on which a support assembly is mounted. The support assembly is vertically mounted, and connecting assemblies are mounted at both ends of the frame assembly, with the connecting assemblies being fixedly connected to the frame assembly.

[0007] Optionally, the frame assembly includes a portal frame, with both ends of the portal frame fixedly connected to the connecting assembly, and the supporting assembly located at the center of the portal frame.

[0008] Optionally, multiple support components are arranged opposite each other on the portal frame, the multiple support components have the same height, and the multiple support components are arranged symmetrically about the center line of the portal frame.

[0009] Optionally, the support assembly includes a fixed cylinder body, which is fixedly connected to the gantry frame. A piston is slidably connected inside the fixed cylinder body, and the bottom end of the piston extends out from inside the fixed cylinder body. When the piston is completely inside the fixed cylinder body, the bottom end of the piston is higher than both ends of the gantry frame. When the piston extends out from the fixed cylinder body, the bottom end of the piston is lower than both ends of the gantry frame.

[0010] Optionally, the gantry frame includes a centrally located elevated section, with support sections fixedly connected to both ends of the elevated section, and the bottom of the elevated section being higher than the top of the driver's cab observation window.

[0011] Optionally, the bottom end of the piston is hinged to a support surface, and the bottom end of the support surface is a planar structure.

[0012] Optionally, the connection between the raised section and the support section is arc-shaped, with the center of the arc located at the end away from the driver's cab.

[0013] Optionally, the connecting assembly includes a flange, one end of which is fixedly connected to the frame assembly, and the other end of which is fixedly connected to the flange plate at the front of the chassis vehicle.

[0014] Optionally, the support assembly is hinged to the frame assembly.

[0015] In summary, the present invention has at least one of the following beneficial technical effects:

[0016] 1. During operation, the mechanism possesses sufficient strength and rigidity while ensuring the driver's visibility. By optimizing the overall structural form of the support mechanism, structural rigidity is effectively improved, and the total weight of the support mechanism is reduced.

[0017] 2. Under different erection conditions, the equipment can be adapted to the erection of different bridges by adding auxiliary supports. When erecting short bridges, the auxiliary supports can be retracted without affecting the chassis deck; when erecting combined bridges, the auxiliary supports can reduce the deformation of the support structure.

[0021] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0023] The support structure plays a crucial role in the erection and dismantling of impact bridges. As a fulcrum, it supports the overall weight of the bridge and the erection system, playing a vital role in the erection, maintenance, and dismantling of the bridge. During bridge erection, the design of the support structure must consider various factors, including the bridge's weight, span, terrain conditions, and external forces and vibrations that may be encountered during construction. The support structure needs to be able to stably support the entire bridge structure, ensuring safety and stability during construction. During dismantling, the support structure also plays a vital role. It needs to be able to effectively support the weight of the bridge to ensure that no accidents occur during dismantling and dismantling. Furthermore, the support structure needs to have a certain degree of flexibility to adjust and adapt to the actual conditions during dismantling.

[0024] Regarding the aforementioned technologies, the inventors believe that when erecting short bridges, the support mechanism relies on the strength of its own structure. However, when erecting combined bridges, the longitudinal beams between the extended support and the chassis deck can cause bending deformation of the working rocker arm, leading to dangerous operations.

[0025] To reduce rocker arm deformation during operation, ensure the stable and reliable erection of combined bridges, and guarantee the smooth progress of the work, this invention provides a support base for a bridge erection mechanism.

[0026] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0027] This invention discloses a support base for a bridge erection mechanism. (Refer to...) Figure 1 , Figure 2A support base for a bridge erection mechanism includes a frame assembly 1, on which an auxiliary support assembly 2 is mounted. The auxiliary support assembly 2 is located on the frame assembly 1 and is relatively vertically arranged. The auxiliary support assembly 2 contacts the lower flange 31 with the chassis vehicle's tilting deck, thereby reducing the pressure on the portal frame structure during the erection of the combined bridge and minimizing deformation of the support assembly. Connecting assemblies 3 are located at both ends of the auxiliary support assembly 2, fixing it to the flange plates on both sides of the front of the chassis vehicle. The gap between the auxiliary support assembly 2 and the chassis vehicle deck provides good visibility for the driver, ensuring stable and reliable operation. During short bridge erection, the strength of the portal frame structure itself is primarily relied upon to support the weight of the bridge and the erection mechanism, completing the erection and dismantling process.

[0028] The auxiliary support assembly 2 includes a portal frame 11, which includes a raised section 111 located at the center. Support sections 112 are fixedly connected to both ends of the raised section 111. The connection between the support section 112 and the raised section 111 is an arc-shaped structure, and the center of the arc is located at the end of the support section 112 and the raised section 111 that is away from the cab.

[0029] The bottom edge of the elevated section 111 is higher than the top of the observation window of the cab, so that the elevated section 111 can maintain the driver's good vision, reduce obstruction to the driver, and ensure the stability of operation.

[0030] The auxiliary support assembly 2 includes a hydraulic cylinder 21 located on the gantry frame 11. The hydraulic cylinder 21 includes a fixed cylinder body 211, and a piston 212 is coaxially and slidably connected inside the fixed cylinder body 211. The top end of the fixed cylinder body 211 is hinged to the side wall of the gantry frame 11. A support surface 213 is hinged to the end of the piston 212 away from the fixed cylinder body 211, and the end of the support surface 213 away from the piston 212 is a planar structure. By hinged between the fixed cylinder body 211 and the gantry frame 11, and by hinged between the support surface 213 and the piston 212, the fixed cylinder body 211 can be in a vertical state, and the support surface 213 hinged to the piston 212 can stably support the surface of the supported equipment.

[0031] When the piston 212 is fully inside the fixed cylinder 211, the bottom end of the piston 212 is lower than the side walls of the connecting components 3 on both sides, thereby reducing the impact of the piston 212's movement. When the piston 212 extends out from the side wall of the fixed cylinder 211, the bottom end of the piston 212 is lower than the bottom end of the connecting components 3, thereby being supported by the support surface 213 at the bottom end of the piston 212.

[0032] Multiple hydraulic cylinders 21 are arranged opposite each other on the portal frame 11. The multiple hydraulic cylinders 21 are arranged along the width direction of the portal frame 11 and are symmetrically arranged about the central axis of the portal frame 11. The bottom height of the multiple hydraulic cylinders 21 opposite each other is the same.

[0033] The connecting assembly 3 includes a flange 31. One end of the flange 31 is fixedly connected to the end of the gantry frame 11, and the other end of the flange 31 is fixedly connected to a flange plate at the front of the chassis vehicle. By having the flange 31 contact the chassis vehicle, the deformation of the rocker arm during operation is reduced, allowing the lower bridge section to reach the connection position with the upper bridge section, thus completing the bridge connection work and ultimately the bridge erection work.
