Description

Technical Field

[0001] The present application relates to the technical field of measuring devices, and in particular to a pot-type support angle measuring device. Background Art

[0002] With the sustained and rapid development of the economy, my country's transportation industry has experienced rapid growth, with the total number of bridges increasing and the types of bridges becoming increasingly diverse. To meet the needs of modernization and promote harmonious development among regions, there is an increasing number of long-span bridges, mainly cable-stayed bridges, continuous box girder urban viaducts, and suspension bridges.

[0003] Pot-type bearings have the characteristics of large horizontal displacement, flexible rotation, light weight, compact structure, simple construction, low building height, easy processing and manufacturing, and reduced cost. They are widely used in large-span bridges. Pot-type bearings need to be quality inspected when they leave the factory, and their maximum and minimum rotation angles must be measured to determine the range of angles that the pot bearing can rotate and whether the quality of the pot bearing meets the design requirements.

[0004] The usual method for measuring the rotation angle of a pot-type bearing is to measure the offset of the upper cover of the pot-type bearing using an electronic distance measuring tool, and then calculate the maximum and minimum angles that the pot-type bearing can rotate based on the offset, and compare them with the design requirements to determine whether the quality meets the standards.

[0005] With respect to the above-mentioned related technologies, the inventors believe that after using an electronic distance measuring tool to measure the height of the upper cover, calculation is still required to obtain the size of the turning angle, which has the defect of being troublesome to measure. Summary of the Invention

[0006] In order to achieve the effect of convenient measurement, the present application provides a pot-type support angle measuring device.

[0007] The present application provides a pot-type support angle measurement device that adopts the following technical solutions:

[0008] A pot-type support angle measuring device includes a bearing block, a measuring plate and an auxiliary plate. The measuring plate and the bearing block are arranged in parallel, the measuring plate and the bearing block are slidingly connected, and the sliding direction is perpendicular to the measuring plate. The auxiliary plate is rotatably connected to one end of the measuring plate, and the rotation axis and the measuring plate and the auxiliary plate are all parallel. A semicircular angle ruler is installed on the measuring plate, and the semicircular angle ruler is used to measure the angle between the bearing block and the auxiliary plate.

[0009] By adopting the above technical solution, when it is necessary to measure the rotation angle of the pot-type support, slide the measuring plate so that the measuring plate and the lower end of the pot-type support upper cover are at the same height, rotate the auxiliary plate so that the auxiliary plate and the pot-type support upper cover are abutted, and at this time, the smaller reading of the semicircular angle ruler corresponding to the pot-type support upper cover is the rotation angle of the pot-type support, thereby achieving the effect of convenient measurement.

[0010] Optionally, a plurality of fixing cylinders are fixed to one side of the bearing block close to the measuring plate, and a plurality of connecting rods are fixed to one end of the measuring plate close to the bearing block. The connecting rods slide in the fixing cylinders, and the fixing cylinders and the connecting rods correspond one to one.

[0011] By adopting the above technical solution, the connecting rod slides in the fixed cylinder, thereby sliding the measuring plate, thereby achieving the effect of sliding the measuring plate.

[0012] Optionally, a screw is provided on the outer wall of the fixing cylinder, the screw passes through the fixing cylinder and is tightly abutted against the connecting rod, and the screw and the fixing cylinder are threadedly connected.

[0013] By adopting the above technical solution, the screw rod and the connecting rod are tightly abutted, thereby fixing the connecting rod and the fixing cylinder. When the measuring plate needs to be slid, the bolt is loosened and the measuring plate is slid. When the measuring plate is slid to the desired position, the bolt is tightened again to fix the connecting rod and the fixing cylinder, thereby achieving the effect of fixing the connecting rod and the fixing cylinder.

[0014] Optionally, a reinforcement spring is provided in the fixing cylinder, one end of the reinforcement spring is fixedly connected to the fixing cylinder, and the other end of the reinforcement spring is fixedly connected to the connecting rod.

[0015] By adopting the above technical solution, the setting of the reinforcement spring is connected to the fixing cylinder and the connecting rod, so that the connection between the fixing cylinder and the connecting rod is made stronger, thereby achieving the effect of increasing the connection stability between the fixing cylinder and the connecting rod.

[0016] Optionally, a fixing groove is provided on the bearing block, and the lower cover plate of the basin-type support is embedded in the fixing groove.

[0017] By adopting the above technical solution and setting the fixing groove, the effect of bearing the basin-type support is achieved.

[0018] Optionally, a plurality of limit plates are provided on the bearing block, and the limit plates are rotatably connected to the bearing block. When the rotation angle of the pot-type support is measured, the limit plate portion overlaps with the lower cover plate of the pot-type support.

[0019] By adopting the above technical solution, when the pot-type support is fixed on the bearing block and the rotation angle of the pot-type support is measured, the limit plate is rotated to block the lower cover plate of the pot-type support, thereby fixing the pot-type support and achieving the effect of fixing the pot-type support.

[0020] Optionally, a connecting piece is provided between the auxiliary plate and the measuring plate, the connecting piece is embedded in the measuring plate, the connecting piece and the measuring plate are slidably connected, and the auxiliary plate and the connecting piece are rotatably connected.

[0021] By adopting the above technical solution, when measuring the rotation angles of pot-type supports of different specifications, the thicknesses of the upper cover plate and the lower cover plate are different. Therefore, when the auxiliary plate is rotated to abut against the upper cover plate, the auxiliary plate and the upper cover plate are abutted by sliding the connecting piece, thereby achieving the effect that the measuring device is suitable for pot-type supports of various specifications.

[0022] Optionally, the bottom of the semicircular angle ruler is embedded in the measuring plate, the semicircular angle ruler and the measuring plate are slidably connected, and a plurality of positioning rods are provided on the side wall of the measuring plate, the positioning rods are inserted into the side wall of the measuring plate, and the positioning rods are used to fix the semicircular angle ruler.

[0023] By adopting the above technical solution, when measuring the rotation angle of pot-type supports of different specifications, it is necessary to slide the connecting piece to slide the auxiliary plate. When sliding the auxiliary plate, pull out the positioning rod and slide the semicircular angle ruler at the same time, so that the semicircular angle ruler slides synchronously. When the sliding stops, insert the positioning rod and fix the semicircular angle ruler to measure the rotation angle of the pot-type support, so that the measurement result is more accurate, thereby achieving the effect of more accurate measurement result.

[0024] Optionally, a return spring is provided on the ring sleeve of the positioning rod, one end of the return spring is fixedly connected to the positioning rod, and the other end of the return spring is fixedly connected to the measuring plate.

[0025] By adopting the above technical solution, when it is necessary to pull out the positioning rod and slide the semicircular angle ruler, the positioning rod is pulled out and slid. When the semicircular angle ruler is slid to the desired position, the positioning rod is released. Under the action of the spring, the positioning rod automatically bounces back, achieving a convenient and quick effect.

[0026] Optionally, the auxiliary plate is magnetic.

[0027] By adopting the above technical solution, the auxiliary plate is magnetic. When the auxiliary plate and the upper cover plate of the basin support are abutted, the upper cover plate of the basin support is made of iron material, so that the auxiliary plate and the upper cover plate are adsorbed together, making the connection between the auxiliary plate and the upper cover plate more firm, and the measurement results are more accurate, thereby achieving the effect of more accurate measurement results.
