Description

Technical Field

[0001] The utility model relates to the technical field of positioners for hollow sandwich panel construction, in particular to a positioner for hollow sandwich panel construction. Background Art

[0002] Hollow-web sandwich panels are a specially designed concrete floor slab. Their key feature is a hollow center that reduces weight and material usage while maintaining structural strength and stability. They are widely used in the construction and industrial sectors. During construction, to ensure the precise installation of sandwich panels, locators such as laser rangefinders are often used to mark reference lines and ensure the correct setting of reference points, enabling workers to quickly and accurately secure the panels in their intended locations.

[0003] When using existing locators, a tripod is usually used to install the locator on an indoor construction floor. Since most indoor construction floors are uneven, the support height of each leg on the tripod needs to be adjusted multiple times to ensure the horizontal state of the locator. This method reduces the convenience of using the locator.

[0004] Therefore, a positioner for hollow sandwich panel construction is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to provide a positioner for hollow sandwich panel construction in order to solve the above problems, thereby improving the problem of needing to adjust the support height of each leg on the tripod multiple times to ensure the horizontal state of the positioner.

[0006] The present invention achieves the above-mentioned object through the following technical solutions: a locator for hollow sandwich panel construction, comprising: a tripod, a laser rangefinder disposed at the top of the tripod; and a leveling mechanism disposed at the top of the tripod. The leveling mechanism comprises a fixing frame fixedly connected to the top of the tripod, a mounting plate rotatably connected to the inner side of the fixing frame, a lower surface end of the laser rangefinder being clamped to the top of the mounting plate, a leveling instrument fixedly connected to the surface of the mounting plate, anti-rotation brackets on both sides of the fixing frame, a friction pad fixedly connected to one side of the anti-rotation bracket, a movable frame disposed at the front end of the fixing frame, and a lower surface end of the fixing frame being slidably connected to the inner wall of the movable frame. Through the mounting plate, fixing frame, and leveling instrument, the support angle of the laser rangefinder can be horizontally adjusted to maintain the laser rangefinder in a horizontal state. Compared with the existing method of repeatedly adjusting the support height of the legs on the tripod to ensure the horizontal state of the locator, this method of adjusting the horizontal state of the laser rangefinder is more convenient and labor-saving, thereby improving the convenience of using the locator for hollow sandwich panel construction.

[0007] Preferably, the front end of the fixed frame is fixedly connected to a positioning frame, the inner wall of the movable frame is fixedly connected to a mounting block, the inner wall of the mounting block is slidably connected to a clamping frame, and the opposite ends of the clamping frame and the mounting block are fixedly connected to a spring, and the surface of the clamping frame is clamped to the inner wall of the positioning frame. The movable frame, anti-rotation frame, and friction pads are used to clamp the mounting plate, preventing the mounting plate from rotating on the fixed frame. The spring, long rod, and positioning frame are used to lock the movable frame, ensuring the stability of the mounting plate and the laser rangefinder after adjustment, thereby ensuring the accuracy of the laser rangefinder's measurement.

[0008] Preferably, a guide rod is fixedly connected to the lower end of the surface of the laser rangefinder, and the lower end of the surface of the guide rod is clamped to the inner wall of the mounting plate.

[0009] Preferably, the inner wall of the mounting plate is slidably connected to a long rod, the surface of the long rod being sequentially engaged with the lower ends of the guide rod and the surface of the laser rangefinder. The guide rod ensures that the long rod is accurately engaged with the guide rod and the inner wall of the laser rangefinder.

[0010] Preferably, the inner wall of the long rod is slidably connected to an iron frame, and the inner wall of the long rod is fixedly connected to a magnetic block, and the rear end of the magnetic block is magnetically attracted to the front end of the iron frame. The iron frame and the magnetic block limit the movement distance of the long rod, ensuring that the laser rangefinder is stably mounted on the mounting plate.

[0011] Preferably, a slider is fixedly connected to the surface of the long rod, and the surface of the slider is slidably connected to the inner wall of the mounting plate. The slider limits the distance the long rod moves in the mounting plate, preventing the long rod from falling off the mounting plate during movement.

[0012] Preferably, the lower end of the surface of the guide rod is in a frustum shape.

[0013] Preferably, the front and rear ends of the fixing frame are fixedly connected to a slide bar, and the inner wall of the anti-rotation frame is slidably connected to the surface of the slide bar. The slide bar is used to limit the movement of the anti-rotation frame and ensure that the friction pad can accurately contact the surface of the mounting plate.

[0014] The beneficial effects of the utility model are:

[0015] 1. The support angle of the laser rangefinder can be adjusted horizontally by using the mounting plate, fixing bracket and level gauge, so that the laser rangefinder remains horizontal. Compared with the existing method of repeatedly adjusting the support height of the legs on the tripod to ensure the horizontal state of the locator, this method is more convenient and labor-saving to adjust the horizontal state of the laser rangefinder, and improves the convenience of using the locator for hollow sandwich panel construction.

[0016] 2. The mounting plate is clamped by the movable frame, anti-rotation frame and friction pad to prevent the mounting plate from rotating on the fixed frame. The movable frame is locked by the spring, long rod and positioning frame to ensure the stability of the mounting plate and the laser rangefinder after adjustment, and to ensure the accuracy of the laser rangefinder measurement.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-5As shown, a positioner for hollow sandwich panel construction includes: a tripod 1, with a laser rangefinder 2 provided at the top of the tripod 1; a leveling mechanism 3, which is provided at the top of the tripod 1. The leveling mechanism 3 includes a fixing frame 31 fixedly connected to the top of the tripod 1, a mounting plate 32 rotatably connected to the inner side of the fixing frame 31, the lower end of the surface of the laser rangefinder 2 being clamped to the top of the mounting plate 32, and a spirit level 33 fixedly connected to the surface of the mounting plate 32. Anti-rotation frames 34 are provided on both sides of the fixing frame 31, and a friction pad 35 is fixedly connected to one side of the anti-rotation frame 34. A movable frame 36 is provided at the front end of the fixing frame 31, and the lower end of the surface of the fixing frame 31 is slidably connected to the inner wall of the movable frame 36. Slide rods are fixedly connected to the front and rear ends of the fixing frame 31, and the inner wall of the anti-rotation frame 34 is slidably connected to the surface of the slide rod. The friction pad 35 is a rubber component.

[0025] When it is necessary to construct the hollow sandwich panel, the tripod 1 is placed at the location to be measured indoors, and the tripod 1 is unfolded and its bottom end is against the construction ground. By observing the position of the bubble in the spirit level 33 on the mounting plate 32, when the bubble deviates to one side, it indicates that the laser rangefinder 2 and the mounting plate 32 are in an unlevel state. At this time, the mounting plate 32 is pushed to adjust the angle of the mounting plate 32 and the laser rangefinder 2 on the fixing frame 31, so that the bubble in the spirit level 33 is located in the center position between the two marks, so that the mounting plate 32 and the laser rangefinder 2 are in a level state on the fixing frame 31. At this time, the laser rangefinder 2 is turned on and the laser rangefinder 2 is aimed at the target point such as the corner of the wall or the mark point on the other side to emit a laser and display the distance from the instrument to the target point, and compare it with the data on the design drawing to ensure that it meets the requirements and mark the baseline to accurately determine the installation position of the hollow sandwich panel. After the measurement is completed, the worker uses a special installation tool to quickly and accurately fix the hollow sandwich panel in the predetermined position.

[0026] like Figure 2 and Figure 4 As shown, the front end of the fixed frame 31 is fixedly connected to the positioning frame 38, the inner wall of the movable frame 36 is fixedly connected to the mounting block 37, the inner wall of the mounting block 37 is slidably connected to the clamping frame 39, the opposite ends of the clamping frame 39 and the mounting block 37 are fixedly connected with a spring 310, and the surface of the clamping frame 39 is clamped to the inner wall of the positioning frame 38.

[0027] Push the movable frame 36, so that the two fixed frames 31 move in the movable frame 36 and approach each other. The movement of the fixed frame 31 drives the friction pad 35 to move, so that the friction pad 35 abuts against the surface of the mounting plate 32, clamping the mounting plate 32. When the rear end of the mounting block 37 abuts against the front end of the positioning frame 38, the pushing of the movable frame 36 is stopped. At this time, the elastic force of the spring 310 pushes the clamping frame 39 to move, so that the clamping frame 39 is clamped in the positioning frame 38, so that the two sets of friction pads 35 stably clamp the surface of the mounting plate 32, so that the mounting plate 32 is locked on the fixed frame 31.

[0028] like Figure 2 、 Figure 3 and Figure 5 As shown, the lower end of the surface of the laser rangefinder 2 is fixedly connected to a guide rod 315, the lower end of the surface of the guide rod 315 is clamped to the inner wall of the mounting plate 32, the inner wall of the mounting plate 32 is slidably connected to a long rod 312, the surface of the long rod 312 is sequentially clamped to the guide rod 315 and the lower end of the surface of the laser rangefinder 2, the inner wall of the long rod 312 is slidably connected to an iron frame 314, the inner wall of the long rod 312 is fixedly connected to a magnetic block 313, the rear end of the magnetic block 313 is magnetically attracted to the front end of the iron frame 314, the surface of the long rod 312 is fixedly connected to a slider 311, the surface of the slider 311 is slidably connected to the inner wall of the mounting plate 32, and the lower end of the surface of the guide rod 315 is frustum-shaped.

[0029] The laser rangefinder 2 is accurately clamped in the mounting plate 32 through the guide rod 315, and the long rod 312 is pushed so that the long rod 312 is clamped in the guide rod 315 and the laser rangefinder 2 in turn. After the long rod 312 moves to the appropriate position, it pushes the iron frame 314 to move so that the iron frame 314 is adsorbed on the magnetic block 313, so that the laser rangefinder 2 is stably mounted on the mounting plate 32.

[0030] When the utility model is in use, the tripod 1 is placed at a location to be measured indoors, the tripod 1 is unfolded and its bottom end is in contact with the construction ground, and the position of the bubble in the level 33 on the mounting plate 32 is observed. When the bubble deviates to one side, it indicates that the laser rangefinder 2 and the mounting plate 32 are in an unlevel state. At this time, the mounting plate 32 is pushed to adjust the angle of the mounting plate 32 and the laser rangefinder 2 on the fixing frame 31, so that the bubble in the level 33 is located at the center position between the two marks, so that the mounting plate 32 and the laser rangefinder 2 are in a level state on the fixing frame 31, and the movable frame 36 is pushed to make the two fixing frames 31 approach each other and drive the friction pad 35 to contact the surface of the mounting plate 32. When the mounting block 3 When the rear end of 7 hits the front end of the positioning frame 38, the moving frame 36 is stopped. At this time, the elastic force of the spring 310 pushes the clamping frame 39 to move, so that the clamping frame 39 is clamped in the positioning frame 38, so that the two sets of friction pads 35 stably clamp the surface of the mounting plate 32, so that the mounting plate 32 is locked on the fixed frame 31. At this time, the laser rangefinder 2 is turned on, and the laser rangefinder 2 is aimed at the target point such as the corner of the wall on the other side or the marking point to emit a laser and display the distance from the instrument to the target point, and compare it with the data on the design drawing to ensure that it meets the requirements and mark the baseline, accurately determine the installation position of the hollow sandwich panel, and after the measurement is completed, the worker uses a special installation tool to quickly and accurately fix the hollow sandwich panel in the predetermined position.

[0031] It should be noted that the tripod 1, laser rangefinder 2, level 33 and magnetic block 313 in the above description are all relatively mature devices in existing technology. The specific models can be selected according to actual needs. At the same time, the laser rangefinder 2 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0032] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
