Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge erecting equipment, and in particular to a middle support mechanism with extensible bridge erecting operation and a chassis vehicle. BACKGROUND

[0002] During the driving and operation of the bridge equipment, the middle support mechanism is required to support the overall weight of the bridge. Due to the limitation of the overall weight of the equipment, the middle support mechanism is required to be light and easy to operate, and to meet the requirements of different erecting conditions. The existing middle support mechanism is connected with the deck of the chassis vehicle by setting symmetrical support mechanisms on both sides of the middle of the chassis vehicle, and serves as a fulcrum to support the overall weight of the bridge during the transportation and operation of the bridge.

[0003] In order to ensure the safety during the operation, the existing middle support mechanism can only support a bridge with one width, and cannot adapt to the operation of bridges with different widths. When the operation of bridges with different width specifications is required, the corresponding middle support mechanism needs to be redesigned, which is time-consuming and laborious and can cause secondary damage to the chassis. SUMMARY

[0004] To solve the above problems, the embodiment of the present application provides a middle support mechanism with extensible bridge erecting operation, which is used for adapting to bridges with different widths during erecting operation or withdrawing operation.

[0005] The embodiment of the present application provides a middle support mechanism with extensible bridge erecting operation, which comprises:

[0006] a guide seat, a middle support oil cylinder, a base, a middle support overturning oil cylinder and a support swing arm.

[0007] The guide seat is used for supporting the inner main beam part of the bridge during the operation, and bears the weight of the bridge.

[0008] The middle support oil cylinder is embedded in the support arm of the guide seat, and controls the height of the guide seat through the extension and contraction of the oil cylinder.

[0009] The base fixes the entire middle support mechanism on the deck of the middle of the chassis vehicle.

[0010] The middle support overturning oil cylinder is fixed at one end on the base and at the other end on the double lug seat on the support swing arm, and realizes the lifting and lowering of the support swing arm through the extension and contraction of the oil cylinder.

[0011] The support swing arm is used for supporting the outer main beam of the bridge during the operation, and is fixed at one end on the base to realize the rotation function.

[0012] In some embodiments, the middle support mechanism further comprises:

[0013] The extended swing arm is used to support the outer main beam of the bridge during the operation of a wider bridge. One end is connected to the support swing arm through a pin, which can realize the rotation function.

[0014] In some embodiments, the two central support mechanisms are respectively located on both sides above the central deck of the chassis vehicle, behind the cab.

[0015] In some embodiments, during equipment operation, the support arm is raised to support the weight of the bridge. During the erection and dismantling of the bridge, the support arm is raised to assist in the operation and reduce the deformation of other erection mechanisms due to the weight of the bridge.

[0016] In some embodiments, the extended swing arm and the supporting swing arm are hinged together and supported by a special-shaped stop. When no support is needed, they are separated by the weight of the extended swing arm without affecting the normal operation of the equipment.

[0017] In some embodiments, the bottom of the base is welded to the deck in the middle of the chassis vehicle and is connected to the support swing arm and the middle support tilting cylinder by means of a hinge, thus serving as a support for the middle tilting cylinder.

[0018] In some embodiments, the bottom of the support swing arm is welded to the central support tilting cylinder, and the swing arm is raised and lowered during bridge operation by extending and retracting the central support tilting cylinder.

[0019] In some embodiments, the extended swing arm and the supporting swing arm achieve support on the same plane through two stops. When support is not needed, the extended support naturally separates from the supporting swing arm by its own gravity.

[0020] This invention provides a chassis vehicle equipped with a central support mechanism as described in any of the above embodiments. Two central support mechanisms are respectively disposed on both sides above the central deck of the chassis vehicle, behind the driver's cab.

[0021] The beneficial effects of the above embodiments of the present invention include:

[0022] The overall structure of the central support mechanism is optimized. By setting an extension mechanism on the outer edge of the central support mechanism, it can adapt to the operational needs of erecting or dismantling bridges of wider specifications. The operation is convenient and efficient, ensuring the stability and reliability of the operation. Attached Figure Description

[0033] Figure 1 This is a schematic diagram of an extendable central support structure for bridge erection operations, according to an embodiment of the present invention.

[0034] This invention provides an extendable central support mechanism for bridge construction operations, such as... Figure 1 As shown, the central support structure 100 includes:

[0035] Guide seat (1), central support cylinder (2), base (3), central support tilting cylinder (4), support swing arm (5) and extension swing arm (6).

[0036] The guide seat (1) is used to support the inner main beam of the bridge during operation and bear the weight of the bridge.

[0037] The central support cylinder (2) is embedded in the support arm of the guide seat (1) and the height of the guide seat (1) is controlled by the extension and retraction of the cylinder.

[0038] The base (3) secures the entire central support mechanism (100) to the deck in the middle of the chassis vehicle.

[0039] The middle support tilting cylinder (4) is fixed at one end to the base (3) and at the other end to the double ear seat on the support swing arm (5). The support swing arm (5) is raised and lowered by the extension and retraction of the cylinder.

[0040] The support arm (5) is used to support the outer main beam of the bridge during operation. One end is fixed to the base (3) by a pin, which can realize the rotation function.

[0041] In some embodiments, the central support structure (100) further includes:

[0042] The extended swing arm (6) is used to support the outer main beam of the bridge during the operation of a wider bridge. One end is connected to the support swing arm (5) by a pin, which can realize the rotation function.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, the two central support mechanisms (100) are respectively located on both sides above the central deck of the chassis vehicle, behind the cab.

[0044] In some embodiments, during the equipment's operation, the support arm (5) is raised to support the weight of the bridge. During the erection and dismantling of the bridge, the support arm (5) is raised to assist in the operation and reduce the deformation of other erection mechanisms due to the weight of the bridge.

[0045] In some embodiments, the extended swing arm (6) and the supporting swing arm (5) are connected by a hinge and supported by a special-shaped stop. When no support is needed, they are separated by the gravity of the extended swing arm (6) without affecting the normal operation of the equipment.

[0046] In some embodiments, the bottom of the base (3) is welded to the deck in the middle of the chassis vehicle and is connected to the support swing arm (5) and the middle support tilting cylinder (4) by means of hinge, so as to serve as a support for the middle tilting cylinder (4).

[0047] In some embodiments, the bottom of the support swing arm (5) is welded to the middle support tilting cylinder (4), and the swing arm is raised and lowered during bridge operation by extending and retracting the middle support tilting cylinder (4).

[0048] In some embodiments, the extended swing arm (6) and the support swing arm (5) achieve support on the same plane through two stops. When support is not needed, the extended support naturally separates from the support swing arm (5) by its own weight.

[0049] This invention provides a chassis vehicle, such as... Figure 2 and Figure 3 As shown, a central support mechanism (100) as described in any of the above embodiments is provided. The two central support mechanisms (100) are respectively located on both sides above the central deck of the chassis vehicle, behind the cab.

[0050] The central support mechanism is installed on both sides of the central deck of the chassis vehicle. During equipment movement, the support arms rise to support the weight of the bridge. During bridge erection and dismantling, the support arms rise to assist in the operation and reduce the deformation of other erection mechanisms due to the weight of the bridge. For different bridge operations, the extended arms and support arms are hinged together, using irregularly shaped blocks for auxiliary support. When support is not needed, the extended arms separate under their own weight, without affecting the normal operation of the equipment.

[0051] The central support mechanism of the above embodiments of the present invention, by optimizing the overall structural form of the central support mechanism and by setting an extension mechanism on the outer edge of the central support mechanism, can adapt to the operational needs of erecting or dismantling bridges of wider specifications. It is convenient and easy to operate, and ensures the stability and reliability of the operation, thereby avoiding the need to design a corresponding central support mechanism for bridges of different widths.

[0052] The technical solutions described in the embodiments of this application can be combined arbitrarily without conflict.

[0053] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto.
