A surveying and setting-out device for building engineering

Abstract

This utility model discloses a surveying and setting-out device for building engineering, including a pin and a setting-out mechanism. The setting-out mechanism is provided on the top of the pin. The setting-out mechanism includes a mounting base, a bearing, a reel, a rope, a fixing block, a spring, a hollow toothed sleeve, and a toothed ring. The bearing is installed at the bottom of the mounting base and is movably connected to the reel through the bearing. Pulling down the pull ring moves the hollow toothed sleeve downward and separates it from the toothed ring, thus moving the pin to the next set of positioning points. During the movement, the rope is continuously pulled out. After reaching the fixed position, the pull ring is released, and the spring drives the hollow toothed sleeve to return to its original position and move upward, cooperating with the toothed ring to fix the reel and prevent it from rotating. At this time, the pin can be inserted into the new positioning point. This cycle can achieve a complete setting-out process. Integrating the setting-out component into the top of the pin facilitates movement. At the same time, the rope will not get knotted or tangled during the winding and unwinding process, making the rope more stable and the operation more convenient.

Description

Technical Field

[0001] This utility model relates to the field of construction tools and equipment, and in particular to a surveying and setting-out device for construction engineering. Background Technology

[0002] Construction surveying and setting out refers to the process of determining the specific location and dimensions of a building through a series of measurements and markings during construction to ensure that the building meets design requirements. The specific construction of surveying and setting out involves transferring the lines on the design drawings to the project site, measuring and positioning the lines using surveying equipment, and then laying out the lines based on the fixed points to determine the construction location and facilitate construction.

[0003] Existing construction surveying and setting-out methods have the following drawbacks: They typically employ independent pin and rope structures. First, surveying equipment is used to pinpoint locations. After pinpointing, pins are inserted at the designated locations, and ropes are connected between the pins. Because the pins and ropes are independent structures, the ropes are prone to tangling and knotting during use, and the process of reeling in and unloading the ropes is inconvenient. Therefore, we propose a construction engineering surveying and setting-out device. Utility Model Content

[0004] The main purpose of this utility model is to provide a surveying and setting-out device for building engineering. By setting the setting-out mechanism on the top of the pin, the rope winding and setting-out components are integrated to the top of the pin, which facilitates the quick winding and setting-out of the rope and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A surveying and setting-out device for construction engineering includes a pin and a setting-out mechanism. The setting-out mechanism is provided on the top of the pin. The setting-out mechanism includes a mounting base, a bearing, a reel, a rope, a fixing block, a spring, a hollow toothed sleeve, and a toothed ring. The bearing is installed at the bottom of the mounting base and is movably connected to the reel through the bearing. The rope is wound around the outer circumference of the reel and the end of the rope extends to the outside of the mounting base. The fixing block is welded to the side of the mounting base. The toothed ring is welded to the bottom of the reel. The hollow toothed sleeve is movably connected to the bottom of the inner wall of the mounting base through the spring, and the inner circumferential groove of the hollow toothed sleeve matches the toothed ring.

[0007] Furthermore, it also includes an auxiliary mechanism. An auxiliary mechanism is provided between the pin and the mounting base. The auxiliary mechanism includes a socket, an internal threaded groove, and a screw. The pin has a vertically oriented socket with an internal threaded groove on its inner wall. The screw is welded to the middle of the bottom of the mounting base. Under normal use, the screw is fully screwed into the socket. At this time, the bottom of the mounting base is in contact with the top of the pin, and the cable laying height is low. When there is an obstruction between adjacent positioning points, the screw can be turned along the internal threaded groove. When the screw is turned, the distance between the mounting base and the pin is increased, and the cable laying height is increased so that it can avoid obstacles and keep the cable straight, meeting the needs of different field wiring conditions.

[0008] Furthermore, a rotating ring is movably connected to the top of the mounting base, and the top of the reel is fixed to the bottom of the rotating ring; the rotating ring structure can be directly twisted to drive the rotation of the reel and wind up the rope.

[0009] Furthermore, a locking block is attached to one end of the cord outside the mounting base. The fixing block has a slot inside, and the cord is inserted into the slot. When the locking block is connected to the fixing block, the cord is aligned with the slot and inserted, while the locking block is attached to the surface of the fixing block, thus completing the connection between the end of the cord and the mounting base.

[0010] Furthermore, a connecting rod with a through spring and extending to the outside of the mounting base is welded to the bottom of the hollow toothed sleeve. A pull ring is provided at the bottom of the mounting base and the bottom end of the connecting rod is fixed to the top of the pull ring. The pull ring structure facilitates pulling, and when the pull ring is pulled down, the position of the hollow toothed sleeve can be moved down by the connecting rod.

[0011] Furthermore, the screw is matched with the inner thread groove and screwed into the insertion hole; the cooperation between the thread groove and the inner thread groove facilitates the adjustment of the distance between the mounting base and the pin.

[0012] Compared with the prior art, this utility model has the following advantages: A mounting base structure is provided at the top of the pin. A rope is wound around a spool inside the mounting base. During the unwinding process, points are first marked using a measuring device to determine the positions of each point. Then, a set of pins is inserted and fixed to the starting point. The end of the rope of another set of pins is connected to the fixing block on the side of the fixed pin. Then, the pull ring is pulled down, causing the hollow toothed sleeve to move downwards and separate from the toothed ring. This allows the pin to move to the next positioning point. During the movement, the rope is continuously pulled out. After reaching the fixed position, the pull ring is released, and the spring causes the hollow toothed sleeve to return to its original position and move upwards, cooperating with the toothed ring to fix the spool, preventing it from rotating. At this point, the pin can be inserted to the new positioning point. This cycle allows for complete cable laying. During winding, disconnect the cable end from the pin, pull down the hollow toothed sleeve, and rotate the swivel to wind the cable. Integrate the cable laying assembly onto the top of the pin for easy movement. The cable will not knot or tangle during laying and winding, resulting in more stable cable fixation and easier operation. Under normal use, the screw is fully screwed into the socket, with the bottom of the mounting base against the top of the pin, resulting in a lower cable laying height. When encountering obstructions between adjacent positioning points, the screw can be turned along the inner thread groove. Turning the screw increases the distance between the mounting base and the pin, raising the cable laying height to avoid obstacles and maintain cable straightness, meeting different on-site wiring requirements.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-4 As shown, a construction engineering surveying and setting-out device includes a pin 1 and a setting-out mechanism 2. The setting-out mechanism 2 is provided on the top of the pin 1. The setting-out mechanism 2 includes a mounting base 201, a bearing 202, a reel 203, a rope 205, a fixing block 207, a spring 209, a hollow toothed sleeve 210, and a toothed ring 213. The bearing 202 is installed at the bottom of the mounting base 201 and is movably connected to the reel 203 through the bearing 202. The rope 205 is wound around the outer circumference of the reel 203 and the end of the rope 205 extends to the outside of the mounting base 201. The fixing block 207 is welded to the side of the mounting base 201. The toothed ring 213 is welded to the bottom of the reel 203. The hollow toothed sleeve 210 is movably connected to the bottom of the inner wall of the mounting base 201 through the spring 209, and the inner circumferential groove of the hollow toothed sleeve 210 matches the toothed ring 213.

[0020] The system also includes an auxiliary mechanism 3. An auxiliary mechanism 3 is provided between the pin 1 and the mounting base 201. The auxiliary mechanism 3 includes a socket 301, an inner threaded groove 302, and a screw 303. The pin 1 has a vertically oriented socket 301 with an inner threaded groove 302 on its inner wall. The mounting base 201 has a screw 303 welded to the middle of its bottom. Under normal use, the screw 303 is fully screwed into the socket 301. At this time, the bottom of the mounting base 201 is in contact with the top of the pin 1, and the cable laying height is low. When there are obstructions between adjacent positioning points, the screw 303 can be turned along the inner threaded groove 302. When the screw 303 is turned, the distance between the mounting base 201 and the pin 1 is increased, raising the cable laying height so that it can avoid obstacles, keep the cable straight, and meet different on-site wiring conditions.

[0021] The mounting base 201 is movably connected to a rotating ring 204 at its top, and the top end of the reel 203 is fixed to the bottom of the rotating ring 204. The rotating ring 204 can be directly twisted to drive the rotation of the reel 203 and wind up the rope 205.

[0022] The cord 205 is attached to a locking block 206 at one end outside the mounting base 201. The fixing block 207 has a slot 208 inside, and the cord 205 is inserted into the slot 208. The hollow toothed sleeve 210 has a through spring 209 welded to its bottom and a connecting rod 211 extending to the outside of the mounting base 201. The mounting base 201 has a pull ring 212 at its bottom, and the bottom end of the connecting rod 211 is fixed to the top of the pull ring 212. When the locking block 206 is connected to the fixing block 207, the cord 205 is aligned with the slot 208 and inserted. At the same time, the locking block 206 is attached to the surface of the fixing block 207, thus completing the connection between the end of the cord 205 and the mounting base 201. The pull ring 212 structure makes it easy to pull. When the pull ring 212 is pulled down, the connecting rod 211 can drive the hollow toothed sleeve 210 to move downward.

[0023] The screw 303 is matched with the inner thread groove 302 and screwed into the insertion hole 301; the screw groove and the inner thread groove 302 cooperate to facilitate the adjustment of the distance between the mounting base 201 and the pin 1.

[0024] It should be noted that this utility model is a surveying and setting-out device for construction engineering. In use, a mounting base 201 is provided on the top of the pin 1. Inside the mounting base 201, a rope 205 is wound around a reel 203. During the setting-out process, points are first marked using a measuring device to determine the positions of each point. Then, a set of pins 1 is inserted and fixed to the starting point. The end of the rope 205 of another set of pins 1 is connected to the fixing block 207 on the side of the fixed pin 1. Then, the pull ring 212 is pulled down, causing the hollow toothed sleeve 210 to move downwards and separate from the toothed ring 213. This allows the pin 1 to move to the next set of positioning points. During the movement, the rope 205 is continuously pulled out. After reaching the fixed position, the pull ring 212 is released, and the spring 209 causes the hollow toothed sleeve 210 to return to its original position and move upwards, cooperating with the toothed ring 213 to fix the reel 203, preventing it from rotating. At this point, the pin 1 is inserted to the new positioning point. The entire wire feeding process can be completed by simply placing the wire at the designated point and repeating this cycle. When winding up, disconnect the end of the wire 205 from the pin 1, pull down the hollow toothed sleeve 210 and rotate the swivel 204 to wind up the wire 205. Integrate the wire feeding assembly into the top of the pin 1 for easy movement. At the same time, the wire 205 will not get tangled or twisted during the wire feeding and winding process, making the wire 205 more stable and the operation more convenient. Under normal use, the screw 303 is fully screwed into the socket 301. At this time, the bottom of the mounting base 201 is in contact with the top of the pin 1, and the wire feeding height is low. When there are obstructions between adjacent positioning points, the screw 303 can be turned along the inner screw groove 302. When the screw 303 is turned, the distance between the mounting base 201 and the pin 1 is increased, raising the arrangement height of the wire 205 so that it can avoid obstacles and keep the wire straight, meeting the needs of different on-site wiring conditions.
