Abstract
Description
Technical Field
[0001] This utility model relates to the field of surveying and setting out technology, and in particular to a surveying and setting out device. Background Technology
[0002] As a surveying technique, surveying and setting out involves the three-dimensional positioning measurement of any spatial object. Its specific work is reflected in the determination of three quantities: distance, angle, and elevation. Regardless of the method used for setting out, it always involves using various instruments to measure these three quantities and then marking them on the construction site. Setting out is one of the main contents of engineering surveying research. Surveying and setting out equipment is a data acquisition, processing, and output device designed and manufactured for surveying operations. The surveying equipment is fixed by a tripod.
[0003] Chinese Patent Publication No. C1-5220623581U discloses a surveying and setting-out auxiliary device, relating to the field of surveying and setting-out technology. It includes a support block with a telescopic component for providing support. The telescopic component has a fixing component for fixing and an adjustment component for fine-tuning. The adjustment component includes a threaded rod with fixing plates fixedly connected to both ends. A nut is rotatably connected to the outside of the threaded rod, and a sliding block is rotatably connected to the outside of the nut. The adjustment component has a limiting component for fixing the position, and multiple fixing blocks are fixedly connected to the outside of the support block. This invention, through the design of the telescopic and adjustment components, achieves fine-tuning of the sliding rod's position through the cooperation of the sliding block, threaded rod, connecting plate, nut, and fixing plate, avoiding the need for manual control of the telescopic rod's adjustment distance by the surveyor during use.
[0004] In the aforementioned patent, the extension length of the outrigger is controlled by adjusting the position of the limiting component. However, during adjustment, the adjusting component moves along with the extension of the outrigger. When adjusting multiple outriggers, it is necessary to bend over to adjust them, which is not convenient for the rapid adjustment of the outriggers. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a surveying and setting-out device in order to solve the technical problems mentioned in the background art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A surveying and setting-out device includes a connecting plate, a surveying camera is provided at the top of the connecting plate, and a rotating groove is provided at each of the three top corners of the bottom end of the connecting plate. A support ring is provided on the top wall of the rotating groove, and an extension leg is rotatably connected to the bottom end of the support ring.
[0008] The extended outrigger includes an outrigger sleeve rotatably connected to the support ring. An extended outrigger is slidably disposed inside the outrigger sleeve. An adjusting screw hole is provided inside the extended outrigger. A threaded rod is provided inside the adjusting screw hole. A connecting tube is provided at the top of the threaded rod. A connecting worm gear is provided on the outer peripheral wall of the connecting tube. A rotating groove is provided at the position corresponding to the connecting worm gear on the outrigger sleeve. An adjusting mechanism is provided at the position corresponding to the rotating groove on the outer wall of the outrigger sleeve.
[0009] Furthermore, the pitch of the threaded rod is much larger than the diameter of the threaded rod.
[0010] Furthermore, the adjustment mechanism includes an outer casing, which is fixedly connected to the side wall of the outrigger sleeve. An adjusting worm is rotatably arranged inside the outer casing, and the adjusting worm cooperates with the connecting worm wheel. Both ends of the adjusting worm are provided with manual adjustment discs.
[0011] Furthermore, an electric push rod is provided inside the connecting pipe, and the extended end of the electric push rod penetrates through the wall of the connecting pipe.
[0012] Furthermore, the inner wall of the connecting worm gear is provided with several locking grooves, and the locking grooves cooperate with the extension end of the electric push rod.
[0013] Furthermore, a connecting rod is inserted into the bottom end of the extended leg. The bottom end of the connecting rod is tapered, and an anti-settlement plate is fitted on the outer periphery of the connecting rod.
[0014] In summary, this utility model has at least one of the following beneficial technical effects:
[0015] 1. The surveying and setting-out device rotates the connecting worm gear by rotating the adjustment mechanism. During the rotation of the connecting worm gear, the connecting pipe and the threaded rod are driven to rotate. During the rotation of the threaded rod, the extension leg is pushed to move in conjunction with the adjustment screw hole. During the movement of the extension leg, the position of the adjustment mechanism does not change, which can effectively improve the convenience of adjusting each leg.
[0016] 2. In this surveying and setting-out device, since the pitch of the threaded rod is much larger than the diameter of the threaded rod, the size of the pitch directly affects the distance the nut can move and the required pushing force. The larger the pitch, the less force is required to move the nut. Because the pitch of the threaded rod is large, the threaded rod can be forced to rotate by pushing the extension leg. Therefore, when storing the device, only a downward force needs to be applied to the device to press the extension leg into the inside of the leg sleeve, thus achieving the purpose of quickly storing the device.
[0017] 3. In this surveying and setting-out device, when adjusting the length of the extended outriggers, the manual adjustment disc is rotated to rotate the adjusting worm gear. The rotation of the adjusting worm gear drives the adjusting worm wheel to rotate. Since the worm wheel cannot drive the worm gear to rotate, the adjusting worm gear can effectively lock the connecting worm wheel, thereby preventing the equipment from tipping over due to the shortening of the extended outriggers during use.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] Example:
[0027] Reference Figure 1 - Figure 5The present invention discloses a surveying and setting-out device, including a connecting plate, a surveying camera is provided at the top of the connecting plate, and a rotating groove is provided at each of the three top corners of the bottom end of the connecting plate. A support ring is provided on the top wall of the rotating groove, and an extension leg is rotatably connected to the bottom end of the support ring.
[0028] The extended outrigger includes an outrigger sleeve rotatably connected to the support ring. An extended outrigger is slidably disposed inside the outrigger sleeve. An adjusting screw hole is provided inside the extended outrigger. A threaded rod is provided inside the adjusting screw hole. A connecting tube is provided at the top of the threaded rod. A connecting worm gear is provided on the outer peripheral wall of the connecting tube. A rotating groove is provided at the position corresponding to the connecting worm gear on the outrigger sleeve. An adjusting mechanism is provided at the position corresponding to the rotating groove on the outer wall of the outrigger sleeve.
[0029] In this embodiment, when setting up the surveying camera, the three extension legs are first manually pried open to the outside to set up the equipment on the ground. The surveying camera is then used to survey and photograph the layout area. When the length of the legs needs to be adjusted, the connecting worm gear can be rotated directly by rotating the adjustment mechanism. During the rotation of the connecting worm gear, the connecting pipe and the threaded rod are driven to rotate. During the rotation of the threaded rod, the extension legs are moved in conjunction with the adjusting screw hole. Furthermore, the position of the adjustment mechanism does not change during the movement of the extension legs, which effectively improves the convenience of adjusting each leg.
[0030] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, the pitch of the threaded rod is much larger than the diameter of the threaded rod.
[0031] In this embodiment, since the pitch of the threaded rod is much larger than the diameter of the threaded rod, the size of the pitch directly affects the distance the nut moves and the required pushing force. The larger the pitch, the less force is needed to push the nut to move. Since the pitch of the threaded rod is large, the threaded rod can be forced to rotate by pushing the extended support leg.
[0032] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, the adjustment mechanism includes an outer casing, which is fixedly connected to the side wall of the outrigger sleeve. An adjusting worm is rotatably installed inside the outer casing, and the adjusting worm cooperates with the connecting worm wheel. Both ends of the adjusting worm are provided with manual adjustment discs.
[0033] In this embodiment, when adjusting the length of the extension leg, the manual adjustment dial is rotated to rotate the adjustment worm gear. The rotation of the adjustment worm gear drives the adjustment worm wheel to rotate. Since the worm wheel cannot drive the worm gear to rotate, the adjustment worm gear can effectively lock the connecting worm wheel, thereby preventing the equipment from tipping over due to the extension leg shortening during use.
[0034] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, an electric push rod is installed inside the connecting pipe, and the extended end of the electric push rod penetrates through the pipe wall of the connecting pipe. The inner wall of the connecting worm gear is provided with several locking grooves, and the locking grooves cooperate with the extended end of the electric push rod.
[0035] In this embodiment, when the connecting worm wheel is rotated by rotating the adjusting worm, the electric push rod is in the extended state. At this time, the electric push rod is inserted into the locking groove, and the connecting worm wheel is fixedly connected to the connecting pipe. This allows the connecting worm wheel to drive the connecting pipe and the threaded rod to rotate when it rotates. After the equipment is used, the electric push rod is in the retracted state. At this time, the connecting worm wheel and the connecting pipe are in a rotating connection state. Therefore, when storing the equipment, only a downward force needs to be applied to the equipment to press the extended leg into the leg sleeve, thus achieving the purpose of quickly storing the equipment.
[0036] In a further preferred embodiment of this utility model, such as Figure 1-5 As shown, a connecting rod is inserted into the bottom end of the extended leg. The bottom end of the connecting rod is tapered, and an anti-settlement plate is fitted on the outer periphery of the connecting rod.
[0037] In this embodiment, the tapered connecting rod facilitates fixation on hard surfaces, while the anti-settlement plate enables the device to be fixed on soft surfaces and prevents the equipment from sinking due to gravity.
[0038] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
