Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy engineering, in particular to a water seal bolt hole positioning and measuring device. Background Art

[0002] The water seal of the ship lift lock head sealing frame is responsible for sealing and stopping the water when the ship compartment is connected to the outside water area, and is one of the key equipment for the safe operation of the ship lift. The water seal needs to be replaced regularly during use. Before the water seal is installed, it is necessary to drill holes according to the location of the installation holes. Therefore, it is necessary to measure and locate the installation holes of the old water seal in advance. When measuring and locating with a three-dimensional laser tracker, it is necessary to place the target ball at the hole position, and use the three-dimensional laser tracker to emit laser to the target ball position. The target ball then reflects the laser to the three-dimensional laser tracker to measure the position of the hole. Since the measurement position is the coordinate of the center of the target ball, it is impossible to guarantee whether the center of the target ball is located on the central axis of the hole position. When measuring the hole position, hexagonal bolts are installed on the hole position, and the bolts are not disassembled during measurement. Therefore, it is necessary to ensure that the center of the target ball can be located on the axis of the hole position during measurement. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a water seal bolt hole positioning and measuring device.

[0004] The purpose of the utility model is achieved through the following technical solutions: a water seal bolt hole positioning and measuring device, comprising:

[0013] In some embodiments, the bottom of the first step at the bottom of the inner wall of the sleeve is provided with an inclined surface, which facilitates sliding the sleeve downward relative to the target ball seat to complete the removal of the sleeve.

[0014] In some embodiments, a bolt hole is provided on the first step of the sleeve at a position corresponding to the mounting hole, the bolt hole passes through the first step and the sleeve, the bolt hole is coaxial with the mounting hole, a locking bolt is threadedly connected to the bolt hole, and the front end of the locking bolt extends into the mounting hole.

The target ball is placed in the groove and is adsorbed by the magnetic component.

[0017] In some embodiments, a connecting hole is provided at the bottom of the groove, and the connecting hole is used to connect the hexagonal slot and the groove. The groove and the hexagonal slot are connected through the connecting hole, so that the magnetic attraction component is located on one side of the hexagonal slot to play the role of absorbing the bolt head, thereby improving the stability of the device after installation.

[0018] The utility model has the following advantages:

[0019] The utility model provides a hexagonal clamping groove at the bottom of the target ball seat so that the target ball seat can be installed on the hexagonal head of the hole position without removing the bolt through the hexagonal clamping groove, and provides a spring top ball structure on the six surfaces of the side wall of the hexagonal clamping groove so that the top ball can abut the bolt head of the bolt, so that the whole device is located on the central axis of the hole position, and then the target ball on the top of the target ball seat is located on the central axis of the hole position, so that the three-dimensional laser tracker can measure the hole position more accurately.
