Description

Technical Field

[0001] This utility model belongs to the field of engineering surveying technology, specifically an engineering surveying and setting-out device. Background Technology

[0002] In modern construction projects, road and bridge construction, water conservancy and hydropower projects, and other infrastructure construction projects, accurate surveying and setting out are key to ensuring project quality and progress. The accuracy of surveying and setting out directly determines whether the location, size, and relative relationships between the various parts of buildings and structures meet the design requirements. If there are deviations in the surveying and setting out, it may lead to serious problems in subsequent construction, such as foundation position deviation and uneven structural stress. This will not only increase project costs but may also affect the safety and service life of the project.

[0003] Early engineering surveying and setting out relied mainly on simple measuring tools, such as measuring rods, steel tapes, and levels. While these tools could meet basic surveying needs to a certain extent, they had obvious limitations. For example, the measuring distance of steel tapes was limited by their length and they were prone to errors due to factors such as stretching and temperature changes. Levels were mainly used to measure elevation differences and had limited ability to measure angles and complex terrain. With the continuous expansion of building scale, increasingly complex structural forms, and gradual improvement of engineering accuracy requirements, traditional measuring tools and methods could no longer meet the needs of modern engineering construction.

[0004] Therefore, this utility model provides an engineering surveying and setting-out device. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, an engineering surveying and setting-out device is proposed.

A drive mechanism is provided on one side of the support leg, and a transmission component is provided on the side of the support leg near the drive mechanism. The support mechanism includes an L-shaped support frame, a fixing ring, and a sliding rod. Two sets of L-shaped support frames are provided, and the two sets of L-shaped support frames are fixedly installed on the top and bottom of the fixing baffle. The side of the L-shaped support frame away from the fixing baffle and close to each other is fixedly installed with the fixing ring. The sliding rod is slidably installed on the inner wall of the L-shaped support frame and the fixing ring. The cooperation between the L-shaped support frame and the fixing ring can prevent the sliding rod from shaking when sliding, and at the same time provide stable support for its use.

[0007] Preferably, the conductor assembly includes a spring and a conductor plate. The spring is fixedly installed at the bottom of the fixing ring and located on the surface of the slide rod. The end of the spring away from the fixing ring is fixedly installed with the conductor plate, and the end of the slide rod near the winding roller is fixedly installed with the conductor plate. In this design, the spring can push the conductor plate with its elastic force to keep it pressed against the coil. The conductor plate can guide and sort the coils on the surface of the winding roller, so that it can release and retract the wire in a regular manner.

[0008] Preferably, the support assembly includes a support rod and a double ball bearing. The support rod is fixedly installed on one side of the fixed baffle, and the inner wall of the support rod is fixedly installed with the double ball bearing. In this scheme, the cooperation between the support rod and the double ball bearing can provide stable support for the rotation of the limiting baffle, and can withstand the tension of the wire during wire feeding. The double ball bearing can also prevent friction between the limiting baffle and the support rod, and ensure smoother rotation.

[0009] Preferably, the wire feeding assembly includes a limiting baffle and a wire feeding roller. The inner wall of the limiting baffle is fixedly installed with the wire feeding roller. The limiting baffle is fixedly installed on the inner wall of the double ball bearing through a rotating shaft. In this scheme, the cooperation between the limiting baffle and the wire feeding roller can guide the wire, effectively distribute the pressure of the wire on the winding roller, and prevent the wire from tangling.

[0010] Preferably, the drive mechanism includes an L-shaped fixed bracket, a motor, a drive gear, and a transmission gear. The L-shaped fixed bracket is fixedly installed on one side of the support leg, and the top of the L-shaped fixed bracket is fixedly installed with the motor. The output end of the motor is fixedly installed with the drive gear. The transmission gear is rotatably mounted on the surface of the drive gear via a connecting rod, and the drive gear meshes with the transmission gear. In this scheme, the cooperation of the L-shaped fixed bracket and the motor enables the drive gear to be driven. The cooperation of the drive gear and the transmission gear enables the power to be transmitted to the gear ring. At the same time, the drive gear, the transmission gear, and the gear ring can form a planetary gear set, which greatly increases the torque of the gear ring and effectively improves its power.

[0011] Preferably, the transmission assembly includes a support fixing plate and a toothed ring. The support fixing plate is fixedly installed on the surface of the winding roller. The side of the support fixing plate away from the winding roller is fixedly installed with the toothed ring. The transmission teeth are located on the inner wall of the toothed ring and mesh with the toothed ring. In this scheme, the cooperation between the support fixing plate and the toothed ring can drive the winding roller through the drive of the transmission teeth, enabling the winding roller to automatically perform unwinding and winding operations.

[0013] 1. The engineering surveying and setting-out device of this utility model, through the arrangement of an L-shaped support frame, a fixing ring and a sliding rod, enables the sliding rod to slide without shaking by the cooperation of the L-shaped support frame and the fixing ring, and at the same time provides stable support for its use.

[0014] 2. The engineering measurement and laying-out device of this utility model, through the setting of spring and guide plate, enables the spring to push the guide plate with its elastic force so that it can always press against the coil, and the guide plate can guide and sort the coil on the surface of the winding roller so that it can lay out and take back the wire in a regular manner.

The support assembly 7 includes a support rod 71 and a double ball bearing 72.

The drive mechanism 9 includes an L-shaped fixed bracket 91, a motor 92, a drive gear 93, and a transmission gear 94. The L-shaped fixed bracket 91... The bracket 91 is fixedly installed on one side of the support leg 2. The top of the L-shaped fixed bracket 91 is fixedly installed with the motor 92.

Then pull the wire end to the surface of the feed roller 82. Finally, start the motor 92 to drive the drive gear 93 to rotate. The rotation of the drive gear 93 will drive the transmission gear 94 to rotate. When the transmission gear 94 rotates, it will drive the gear ring 102 to rotate. The rotation of the gear ring 102 will drive the winding roller 3 to rotate through the support plate 101. The rotation of the winding roller 3 will perform the wire feeding operation. When the winding roller 3 continues to feed the wire, the feed roller 82 will rotate continuously due to the inertia of the wire. When it is necessary to take the wire back, simply start the motor 92 to reverse it. At the same time as taking the wire back, as the winding roller 3 continuously winds up the wire, the spring 61 will push the guide plate 62 to tightly press against the wire to prevent the wire from tangling, so that the wire can be wound in an orderly manner from left to right layer by layer.
