Description

Technical Field

[0001] The utility model relates to the technical field of pipeline construction, in particular to a positioning device for rain and sewage pipeline construction. Background Technique

[0002] Rain and sewage pipelines are an important part of urban infrastructure. They are responsible for collecting and transporting rainwater and domestic sewage, realizing the separate discharge of rainwater and sewage, so as to improve the urban drainage capacity, reduce the phenomenon of waterlogging, and improve the water environment quality. When constructing rain and sewage pipelines, generally, pipelines will be laid, and multiple sections of pipelines need to be connected to form a conveying pipeline with a certain length. When connecting pipelines, a positioning device is generally used to lift the pipeline to a suitable position and then install it, without manual lifting, which is currently widely used.

[0003] Existing pipeline positioning devices generally consist of fixing parts and a lower base, etc. The pipeline is fixed to the fixing parts, and some also set a lifting mechanism under the fixing parts to adjust the height of the pipeline. However, due to the complex on-site construction environment and often involving steps such as ground excavation, it is easy to cause different ground heights. When the positioning device is placed on it, it is easy to cause the positioning device to tilt. Especially when there is a slope on the ground, it is easy to cause the pipeline to tilt, which is not convenient to use. To solve this technical problem, the utility model proposes a positioning device for rain and sewage pipeline construction. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a positioning device for rain and sewage pipeline construction, which can effectively solve the problems mentioned in the background technique.

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

[0006] A positioning device for rain and sewage pipeline construction includes a bottom plate. An adjusting mechanism is arranged on the lower surface of the bottom plate. A first support plate is installed on the upper surface of the bottom plate. A lifting mechanism is also arranged on the upper surface of the bottom plate. A second support plate is arranged above the lifting mechanism. Fixing mechanisms are arranged on the upper parts of the first support plate and the second support plate. A calibration mechanism is arranged on the outer surface of the first support plate. A projection mechanism is arranged outside the second support plate. A spirit level is installed on the upper surface of the bottom plate.

[0007] Preferably, the adjusting mechanism includes a base. A rotating sleeve is rotatably connected to the inner wall of the base. A threaded rod is threadedly connected to the inner wall of the rotating sleeve. The upper surface of the threaded rod is fixedly connected to the bottom plate.

[0008] Preferably, the lifting mechanism includes a telescopic rod. The lower surface of the telescopic rod is fixedly connected to the bottom plate, and the extending end of the telescopic rod is fixedly connected to the second support plate. A limiting rod is slidably connected to the inner wall of the second support plate, and the lower surface of the limiting rod is fixedly connected to the bottom plate.

[0009] Preferably, the fixing mechanism includes a fixing plate. The outer surfaces of the two fixing plates are respectively fixedly connected to the first support plate and the second support plate. One end of the fixing plate is hinged with an opening and closing plate, and the other end of the fixing plate is detachably connected to the opening and closing plate.

[0010] Preferably, the calibration mechanism includes a connecting rod. One end of the connecting rod is fixedly connected to the first support plate, and a calibration plate is installed at the other end of the connecting rod.

[0011] Preferably, the projection mechanism includes a connecting rope. The upper end of the connecting rope is fixedly connected to the fixing plate, and a plumb bob is connected to the lower end of the connecting rope.

[0012] Preferably, a laser emitter is installed on the upper surface of the plumb bob, and a weight is also installed on the upper surface of the plumb bob.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, by providing components such as a calibration mechanism and a projection mechanism, when the laser emitted by the projection mechanism cannot irradiate the center of the calibration mechanism, the fixing mechanism is driven to move up or down by the lifting mechanism, so as to adjust the height of the fixing mechanism, so that the two fixing mechanisms are at the same height, and then the pipeline is installed to prevent the pipeline from tilting, achieving the effect of preventing the pipeline from tilting, thus solving the problem that due to different ground heights, when the positioning device is placed on it, it is easy to cause the positioning device to tilt, especially when there is a slope on the ground, it is easy to cause the pipeline to tilt and is not convenient to use.

[0015] In the utility model, by providing components such as an adjusting mechanism and a lifting mechanism, when the rotating sleeve is rotated, the threaded rod will move up or down, so as to adjust the total length of the adjusting mechanism, drive the bottom plate to move up or down, thus changing the height of the pipeline. At the same time, by observing the state of the spirit level, the bottom plate can be adjusted to be as flat as possible. The second support plate can be driven to move up or down by the telescopic rod. When the second support plate moves, it is limited by the limiting rod to increase the stability of the second support plate and prevent it from tilting and cracking at the connection with the telescopic rod.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, a rain and sewage pipeline construction positioning device includes a bottom plate 1. An adjusting mechanism 2 is provided on the lower surface of the bottom plate 1. The adjusting mechanism 2 includes a base 201. The inner wall of the base 201 is rotatably connected with a rotating sleeve 202. The inner wall of the rotating sleeve 202 is threadedly connected with a threaded rod 203. The upper surface of the threaded rod 203 is fixedly connected with the bottom plate 1. When the rotating sleeve 202 is rotated, the threaded rod 203 will move upward or downward, so as to adjust the total length of the adjusting mechanism 2, drive the bottom plate 1 to move upward or downward, thereby changing the height of the pipeline. At the same time, by observing the state of the spirit level 9, the bottom plate 1 can also be adjusted to be as flat as possible.

[0024] The upper surface of the bottom plate 1 is provided with a first support plate 3. The upper surface of the bottom plate 1 is also provided with a lifting mechanism 4. The lifting mechanism 4 includes a telescopic rod 401. The lower surface of the telescopic rod 401 is fixedly connected to the bottom plate 1. The extended end of the telescopic rod 401 is fixedly connected to a second support plate 5. A limiting rod 402 is slidably connected to the inner wall of the second support plate 5. The lower surface of the limiting rod 402 is fixedly connected to the bottom plate 1. The telescopic rod 401 and the limiting rod 402 are each provided with two. The second support plate 5 can be driven to move up or down by the telescopic rod 401. When the second support plate 5 moves, it is limited by the limiting rod 402 to increase the stability of the second support plate 5 and prevent it from tilting and cracking at the connection with the telescopic rod 401.

[0025] Above the lifting mechanism 4 is provided with a second support plate 5. Fixed mechanisms 6 are provided on the upper parts of the first support plate 3 and the second support plate 5. The fixed mechanism 6 includes a fixing plate 601. The outer surfaces of the two fixing plates 601 are respectively fixedly connected to the first support plate 3 and the second support plate 5. One end of the fixing plate 601 is hinged with a switch plate 602. The other end of the fixing plate 601 is detachably connected to the switch plate 602. By placing the pipeline on the two fixing plates 601 at the same time, then buckling the switch plate 602 and fixing it with bolts, the pipeline can be fixed to the fixing plate 601.

[0026] The outer surface of the first support plate 3 is provided with a calibration mechanism 7. The calibration mechanism 7 includes a connecting rod 701. One end of the connecting rod 701 is fixedly connected to the first support plate 3. The other end of the connecting rod 701 is provided with a calibration plate 702. The connecting rod 701 is provided with two, which are used to support the calibration plate 702.

[0027] A projection mechanism 8 is provided outside the second support plate 5. The projection mechanism 8 includes a connecting rope 801. The upper end of the connecting rope 801 is fixedly connected to the fixing plate 601. The lower end of the connecting rope 801 is connected to a plumb bob 802. The plumb bob 802 has the characteristic of always pointing vertically downward, using gravity to always point to the center of the earth. When the fixing plate 601 is in an inclined state, the plumb bob 802 still remains in a vertical state. A laser emitter 803 is installed on the upper surface of the plumb bob 802. A weight 804 is also installed on the upper surface of the plumb bob 802. By the position where the laser emitter 803 irradiates on the calibration plate 702, the height difference between the two fixing plates 601 can be judged. When the horizontal heights of the two fixing plates 601 are the same, the laser just irradiates on the center position of the calibration plate 702. The weight 804 is provided with three, and the weight of each is the same as that of the laser emitter 803, which is used to balance the weight of the laser emitter 803 and prevent it from affecting the accuracy of the plumb bob 802.

[0028] The upper surface of the bottom plate 1 is equipped with a spirit level 9. There are four adjusting mechanisms 2, which are respectively located at the four corners of the bottom plate 1. Cooperating with the spirit level 9, the flatness of the bottom plate 1 can be adjusted, and the spirit level 9 can be used to detect the flatness of the bottom plate 1.

[0029] It should be noted that during the actual use of the device, first place the bottom plate 1 in a suitable position, adjust the height of the bottom plate 1 by adjusting the four adjusting mechanisms 2, and at the same time level the bottom plate 1. When placed on a slope or with too large an inclination, there will be a height difference between the two fixing mechanisms 6, resulting in the laser emitted by the laser emitter 803 not shining on the center of the calibration plate 702. At this time, drive the second support plate 5 to move up or down through the telescopic rod 401, thereby driving the second fixing mechanism 6 to move up or down, so as to adjust the height of the second fixing mechanism 6. At the same time, the second fixing mechanism 6 drives the projection mechanism 8 to move up or down. When the laser just shines on the middle of the calibration plate 702, stop the movement, so that the two fixing mechanisms 6 are at the same height, and then install the pipeline to prevent the pipeline from tilting, achieving the effect of preventing the pipeline from tilting.
