Description

Technical Field

[0001] The utility model relates to the technical field of mobile trolley equipment, in particular to a prefabricated beam factory mold mobile trolley with an accurate position detection device. Background Art

[0002] A mobile trolley with formwork is a device used in bridge construction. It is mainly used to transport and move large prefabricated components, such as prefabricated beams, during bridge construction. In order to detect the real-time position of the mobile trolley with formwork, it is necessary to install a position detection device on the mobile trolley with formwork. The position detection device is a device used to detect the position of the mobile trolley on the moving path, which is crucial to ensuring construction accuracy and efficiency.

[0003] In the past, the running track wheels on the mold-carrying mobile trolley were welded on different plates, with no vertical continuity, and errors in vertical height were easy to occur during welding; this caused the trolley to move poorly during actual use, and required manual adjustment of the running track wheels. In addition, the commonly used position detection device does not have a retaining spring to ensure that the distance measuring wheel and the trolley running track are always in contact; the distance measuring wheel is prone to slipping and other abnormal phenomena during movement; in addition, the distance measuring wheel and the absolute value encoder in the existing mold-carrying mobile trolley are generally connected by a belt, which has the risk of slipping, resulting in inaccurate measurement data. Utility Model Content

[0004] The utility model provides a prefabricated beam factory with a mold moving trolley with a precise position detection device to solve the technical problems mentioned in the background technology.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] The utility model provides a prefabricated beam factory with a mold mobile trolley with a precise position detection device, comprising:

[0007] A vehicle body, comprising a vehicle frame and a support beam transversely mounted on the vehicle frame;

[0008] A plurality of running track wheels, divided into two groups and symmetrically mounted on the bottom of the support beam;

[0009] The position detection device is installed on one of the walking track wheels, and includes a measuring wheel, an elastic connecting piece, an absolute value encoder, a driving piece and a mounting bracket. The measuring wheel is rotatably connected to the bottom of the mounting bracket, and the measuring wheel abuts against the trolley walking track through the elastic connecting piece. The rotating shaft of the absolute value encoder is transmission-connected to the movable shaft of the measuring wheel through the driving piece.

[0010] Furthermore, the position detection device also includes a mounting bracket;

[0011] The mounting bracket includes a mounting base and a movable bracket rotatably connected obliquely to the end of the mounting base; the distance measuring wheel is rotatably connected to the bottom of the movable bracket; an elastic connecting member is connected obliquely between the mounting base and the movable bracket so that the bottom of the distance measuring wheel abuts against the trolley running track.

[0012] Further, the driving member is a coupling, and the rotating shaft on the absolute encoder is drivingly connected to the movable shaft of the distance measuring wheel through the coupling.

[0013] Further, the driving member is a synchronous belt driving mechanism, and the rotating shaft on the absolute encoder is drivingly connected to the movable shaft of the distance measuring wheel through the synchronous belt driving mechanism.

[0014] Further, the driving member is a gear mechanism, and the rotating shaft on the absolute encoder is drivingly connected to the movable shaft of the distance measuring wheel through the gear mechanism.

[0015] Further, the distance measuring wheel is a steel wheel or a rubber wheel.

[0016] Further, the elastic connecting member is a tension spring, an elastic cord or an elastic buffer rod.

[0017] Advantages of the utility model:

[0018] 1. The utility model provides a precast beam factory formwork-carrying trolley with a precise position detection device.

[0019] In addition, between the rotating shaft of the absolute encoder and the movable shaft of the distance measuring wheel in the position detection device is driven by a driving member, and the driving member includes but is not limited to a coupling, a synchronous belt driving mechanism, a gear mechanism or other driving devices, solving the problem of inaccurate position detection caused by belt slipping in the existing position detection device of the formwork-carrying trolley, and improving the detection accuracy and stability.
