A verticality measuring device for construction engineering

Abstract

The present invention relates to the field of building measurement technology, specifically a verticality measuring device for construction engineering, comprising a sleeve, wherein a guide rod is vertically inserted into the sleeve. The verticality measuring device for construction engineering, by moving a gear to engage with a reversing rack and pushing a slide to move laterally, causes the moving rack on the other side to engage with the moving gear. At this time, the rotating moving gear drives the sliding sleeve to move down along the guide rod along the moving rack. The switching rack can automatically switch the meshing position of the moving gear after the measurement is completed, so that the upward movement process is converted into the downward movement process. On the one hand, there is no need for the user to manually and continuously observe and operate, which reduces the difficulty of the operation and realizes the possibility of a single person operating multiple devices. On the other hand, the switching process is automatically performed after the measuring device is placed on top, avoiding the situation where the manual switching of the up and down movement processes cannot be timely caused by safety hazards.

During this process, the deflection pointer corresponding to the inclination of the wall uses the vertical groove to push the slider to slide a corresponding amount along the slide groove, so that the marking pen draws a wave graph corresponding to the inclination value on the rolled recording paper. Compared with the existing method of using a camera to observe the pointer, the above-mentioned pointer can not only provide real-time observation, but also cooperate with the marking pen to automatically record the inclination value on paper.

The side surface of the plate frame 8 is provided with a scale 12 that matches the pointer 11. The sleeve 1 is placed on the ground close to the building wall. After the measuring roller 7 is attached to the building wall to be measured, the sliding sleeve 3 moves upward along the guide rod 2. The change in the inclination of the wall drives the slide 134 to move along the slide rail 4, and the half gear 9 is driven by the measuring rack 10 to reciprocate and deflect, so that the inclination data is reflected on the scale 12 by the pointer 11.

[0035] An automatic travel component 13 is provided on the sliding sleeve 3 and the guide rod 2 , and the automatic travel component 13 is used to automatically control the sliding sleeve 3 to move up and down.

[0036] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 10 As shown, the automatic stroke component 13 includes a rear wall groove 131 opened along the side surface of the guide rod 2 away from the measuring roller 7, a motor 132 is fixedly provided on the outside of the sliding sleeve 3, and the rotating shaft of the motor 132 passes through the sliding sleeve 3 and extends into the rear wall groove 131.

[0037] A moving gear 133 is fixedly connected to the rotating shaft of the motor 132 .

[0038] The interior of the rear wall groove 131 is laterally slidably connected with a rectangular slide 134, and the inner side walls on both sides of the slide 134 are provided with moving racks 135 that cooperate with the moving gear 133 to make the slide 3 move up and down. The inner top wall of the slide 134 is provided with a reversing rack 136 that cooperates with the moving gear 133 to make the slide 3 move laterally to switch the moving racks 135 on both sides. The starting motor 132 drives the moving gear 133 to rotate, so that the moving gear 133 drives the slide 3 along the guide rod 2 along the moving rack 135 on one side. After the moving gear 133 moves up and is placed on the top along the moving rack 135 on one side, when the current wall measurement is completed, the moving gear 133 is meshed with the reversing rack 136 and pushes the slide to move laterally, so that the moving rack 135 on the other side meshes with the moving gear 133. At this time, the rotating moving gear 133 drives the slide 3 along the moving rack 135 to move down along the guide rod 2.

[0039] A recording assembly 137 is provided on the slide rail 4 , the plate frame 8 , the slide sleeve 3 and the guide rod 2 .

[0040] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 10 As shown, the recording component 137 includes a slide groove 1371 opened horizontally along the side surface of the frame 8, and a slider 1372 is slidably connected in the slide groove 1371, a vertical groove 1373 is opened on the surface of the pointer 11, one end of the slider 1372 extends into the vertical groove 1373, and a marking pen 1374 is provided on the side of the slider 1372 away from the pointer 11. The deflection pointer 11 corresponding to the inclination of the wall uses the vertical groove 1373 to push the slider 1372 to slide a corresponding amount along the slide groove 1371.

[0041] A front wall groove 1375 is defined on the side of the guide rod 2 facing the slide rail 4 , and a retractable rack 1376 is defined on the inner sidewall of the front wall groove 1375 .

[0042] A suspension 1377 is fixedly installed inside the plate frame 8, and two rotating shafts 1378 are rotatably installed on the suspension 1377. The ends of the two rotating shafts 1378 relative to the sliding sleeve 3 both penetrate the sliding sleeve 3 and extend into the front wall groove 1375, and the penetrating ends of the rotating shafts 1378 are fixedly connected to the retracting and releasing gears 1379.

[0043] The two rotating shafts 1378 have recording paper 13710 rolled up that matches the marking pen 1374. When the sleeve 3 moves up along the guide rod 2 for measurement, the retracting gear 1379 on the sleeve 3 is rotated along the retracting rack 1376, and the rotating shaft 1378 is rotated to roll the recording paper 13710, so that the marking pen 1374 draws a wave graph corresponding to the tilt value on the rolled recording paper 13710.

[0044] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 10 As shown, a base is welded to the bottom of the sleeve 1, and adjustable feet are rotatably provided at the four corners of the bottom surface of the base. The entire equipment is firmly placed on the ground using the base counterweight and the feet.

[0045] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 10 As shown, a replacement opening that matches the recording paper 13710 is provided on the top of the plate rack 8, and the user can quickly replace the recording paper 13710 on the rotating shaft 1378 along the replacement opening.

[0046] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 10 As shown, a groove is provided on the side surface of the slider 1372, and the marking pen 1374 is slidably connected in the groove, and a top spring is provided in the groove, which pushes the marking pen 1374 to move outward. During use, the top spring pushes the marking pen 1374 to fit onto the recording paper 13710, ensuring that the marking pen 1374 can make stable records along the surface of the recording paper 13710.

[0047] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figures 5 to 10 As shown, the extended end of the slider 1372 is configured as a rotatably connected cylindrical structure, which can better move in the vertical slot 1373 and reduce wear caused by friction between the two.

[0048] A method for using a verticality measuring device for construction engineering comprises the following steps:

[0049] S1. Place the sleeve 1 on the ground near the building wall, place the measuring roller 7 against the building wall to be measured, and start the motor 132 to drive the moving gear 133 to rotate, so that the moving gear 133 drives the sliding sleeve 3 to move up along the guide rod 2 along the moving rack 135 on one side. During this process, the change in the inclination of the wall drives the slide 134 to move along the slide rail 4, and the half gear 9 is driven by the measuring rack 10 to reciprocate and deflect, so that the inclination data is reflected by the pointer 11 on the scale 12.

[0050] S2. After the moving gear 133 moves up and to the top along the moving rack 135 on one side, when the current wall measurement is completed, the moving gear 133 turns to engage with the reversing rack 136 and pushes the slide to move laterally, so that the moving rack 135 on the other side engages with the moving gear 133. At this time, the rotating moving gear 133 drives the sliding sleeve 3 to move down along the guide rod 2 along the moving rack 135.

[0051] S3, when the sleeve 3 moves up along the guide rod 2 for measurement, the retracting gear 1379 on the sleeve 3 is rotated along the retracting rack 1376, and the rotating shaft 1378 is rotated to roll the recording paper 13710. During this process, the deflection pointer 11 corresponding to the inclination of the wall uses the vertical groove 1373 to push the slider 1372 to slide along the slide groove 1371 for a corresponding amount, so that the marking pen 1374 draws a wave graph corresponding to the inclination value on the rolled recording paper 13710.
