Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a portable laying-out measuring device. Background Art

[0002] Engineering surveying plays a very important role in the planning, construction and management stages of an engineering project. Obtaining spatial data related to engineering construction is an important goal of the surveying process. Engineering surveying can provide reliable and accurate spatial data for design, construction, operation and other links, which can ensure the normal operation of engineering projects, thereby ensuring the speed, quality and effect of engineering construction.

[0003] The existing measuring and setting-out devices for engineering surveying are large in size, difficult to move during measurement, and inconvenient to carry before and after use. During the working process, they need to be manually carried to retract and set the line, which is time-consuming and labor-intensive, thereby reducing work efficiency.

[0004] The existing publication number is CN221055770U, which is a portable line-laying and measuring device for engineering surveying. The positioning rod in the sleeve is taken out, the line is fixed by a ring, the positioning rod is inserted into the ground to fix it, and the universal wheel is pulled by the handle to move it to the length to be measured. This facilitates the fixing and movement of the line when the portable line-laying and measuring device for engineering surveying is actually used. However, when in use, since the anchor point is set by the positioning rod, and the measuring line is wound in an orderly manner from one side to the other along the winding shaft, when the line is pulled for laying-out measurement, the released measuring line, that is, the measuring line between the positioning rod and the winding shaft, will gradually shift with the rotation of the winding shaft, resulting in measurement errors. Utility Model Content

[0005] The purpose of the utility model is to provide a portable laying-out measuring device, which solves the problem that a portable laying-out measuring device for engineering measurement with publication number CN221055770U mentioned in the above background technology is used. Since an anchor point is set by a positioning rod and the measuring line is wound orderly from one side to the other along a winding shaft, when the laying-out measurement is performed, the released measuring line, that is, the measuring line between the positioning rod and the winding shaft, will gradually shift as the winding shaft rotates, resulting in a measurement error.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is a portable line-laying and measuring device, including a base plate, a moving component is arranged at the lower end of the base plate, a fixed plate is fixedly connected to one side of the upper end of the base plate, a connecting rod is fixedly connected to one side of the fixing plate, a screw rod is fixedly connected to the end of the connecting rod, a winding shaft is arranged above the base plate, a measuring line is wound around the outer side of the winding shaft in an orderly manner, a threaded hole is opened inwardly at one end of the winding shaft close to the fixing plate, the winding shaft is threadedly connected to the screw rod through the threaded hole, a fixing sleeve is fixedly connected to the base plate, an insertion rod is arranged in the fixing sleeve, a fixing ring is fixedly connected to the upper end of the insertion rod, and the starting end of the measuring line is tied to the fixing ring.

[0007] As a preferred solution, one end of the winding shaft away from the fixed plate is rotatably connected to a movable plate, a guide groove is provided on the bottom plate, and the bottom plate is slidably connected to the guide groove.

[0008] As a preferred solution, the lower end of the movable plate is rotatably connected to a plurality of guide wheels, and the guide wheels rotate in guide grooves.

The connecting rod passes through an avoidance hole provided on the movable plate and is fixedly connected to the winding shaft.

[0010] As a preferred solution, a rotating handle is eccentrically fixedly connected to a side of the rotating wheel away from the movable plate.

[0011] As a preferred solution, a retractable bellows is sleeved on the outer side of the connecting rod, and two ends of the retractable bellows are rotatably connected to the winding shaft and the fixing plate respectively.

[0012] As a preferred solution, the moving component is a track wheel.

[0013] Compared with the prior art, the beneficial effects of the utility model include:

[0018] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0019] The following will be combined with the instructions attached Figure 1-3 And specific implementation methods are used to describe the above technical solutions in detail:

[0020] The utility model provides a portable laying-out measuring device, including a bottom plate 1, a moving assembly 2 is arranged at the lower end of the bottom plate 1, a fixing plate 3 is fixedly connected to one side of the upper end of the bottom plate 1, a connecting rod 4 is fixedly connected to one side of the fixing plate 3, a screw 5 is fixedly connected to the end of the connecting rod 4, a winding shaft 6 is arranged above the bottom plate 1, a measuring line is orderly wound around the outer side of the winding shaft 6, a threaded hole is opened inwardly at one end of the winding shaft 6 close to the fixing plate 3, the winding shaft 6 is threadedly connected to the screw 5 through the threaded hole, a fixing sleeve 7 is fixedly connected to the bottom plate 1, an insert rod 8 is arranged inside the fixing sleeve 7, a fixing ring 9 is fixedly connected to the upper end of the insert rod 8, and the starting end of the measuring line is tied to the fixing ring 9. The whole device can be moved to the position to be measured by the moving assembly 2, and the whole device is convenient to move and more portable by setting the moving assembly 2. When it is necessary to carry out line laying measurement, the insertion rod 8 is taken out from the fixed sleeve 7 and inserted into the measuring location, and then the entire device is moved by the moving component 2. Preferably, a pull rod can be set on the base plate 1 for movement. Since the measuring line is tied to the fixing ring 9 of the insertion rod 8 fixed in the ground, the measuring line will be elongated with the movement of the entire device. In this process, as the measuring line is elongated, the winding shaft 6 will rotate. Since the winding shaft 6 is connected to the screw rod 5 through a threaded hole, the winding shaft 6 can move relative to the screw rod 5 while rotating. Preferably, the displacement generated by the winding shaft 6 during rotation needs to be calculated and calibrated so that it can be synchronized with the release of the measuring line, so that the released measuring line can always be on the same vertical level, which can effectively avoid the measurement error caused by the deviation of the measuring line.

[0021] As a preferred embodiment, one end of the winding shaft 6 away from the fixed plate 3 is rotatably connected to the movable plate 10, and a guide groove 11 is provided on the bottom plate 1, and the bottom plate 1 is slidably connected to the guide groove 11. By setting the bottom plate 1 to slide in the guide groove 11, the winding shaft 6 can be guided and supported, so that the central axis can move on the same horizontal plane.

[0022] In order to facilitate the movement of the movable plate 10 , as a preferred embodiment, a plurality of guide wheels 12 are rotatably connected to the lower end of the movable plate 10 , and the guide wheels 12 rotate in the guide grooves 11 .

[0023] In order to facilitate the winding, as a preferred embodiment, a rotating wheel 13 is provided on the side of the mobile plate 10 away from the fixed plate 3, and a connecting rod 14 is fixedly connected to the end of the rotating wheel 13 close to the mobile plate 10, and the connecting rod 14 passes through the avoidance hole opened on the mobile plate 10 and is fixedly connected to the winding shaft 6. When winding, the plug rod 8 is pulled out from the ground, one staff member holds the plug rod 8, and another staff member rotates the rotating wheel 13, thereby driving the winding shaft 6 to rotate through the connecting rod 14, so that the winding shaft 6 can rotate along the screw rod 5 and move to reset. With the movement of the winding shaft 6, the measuring line can be wound on the winding shaft 6 in an orderly manner, thereby completing the winding work. In this process, the staff holding the plug rod 8 needs to cooperate with the movement so that the measuring line is always in a straight state to avoid the phenomenon of line explosion.

[0024] In order to facilitate the rotation of the rotating wheel 13 , as a preferred embodiment, a rotating handle 15 is eccentrically fixedly connected to one side of the rotating wheel 13 away from the moving plate 10 .

[0025] Since the laying-out measurement work is mostly carried out outdoors, in order to avoid the influence of the complex outdoor environment or debris on the screw rod 5, as a preferred embodiment, a retractable bellows 16 is sleeved on the outer side of the connecting rod 4, and the two ends of the retractable bellows 16 are respectively rotatably connected to the winding shaft 6 and the fixing plate 3. The retractable bellows 16 can be extended or contracted with the movement of the winding shaft 6, thereby protecting the screw rod 5.

[0026] As a preferred embodiment, the mobile assembly 2 is a track wheel. Moving by the track wheel can adapt to most complex terrain environments, improving its portability and applicability.

The circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.

[0028] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
