Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of surveying and mapping and setting out, in particular to a surveying and mapping and setting out device. Background Art
[0002] Surveying and mapping is required during the construction of water conservancy projects. Through surveying and mapping, engineering drawings of the water conservancy projects under construction are drawn to facilitate subsequent construction.
[0003] During the construction of water conservancy projects, sewer well reconstruction is a construction project that is often required in reconstruction projects. Before construction, operators are required to place surveying buoys or surveying floats (the buoys or floats have sensors for surveying) into the sewer wells, and as the buoys or floats float in the underground horizontal shaft of the sewer well, the sewer wells are mapped. During the construction process, the floats or floats are pulled by the unwinding wire, so that the floats or floats are controlled to flow in the underground horizontal shaft while the wire is released.
[0004] However, in actual work, the rope pulling the floating ball or buoy is easy to scrape against the well wall, resulting in the rope breaking during the line release process. The scraping also causes the buoy or floating ball to no longer float normally in the underground horizontal well.
[0005] Therefore, in the actual working process, the guide wire is inserted into the conduit and placed in the vertical well of the sewer. However, in the actual working process, the floating pull rope pulls the guide wire, causing the guide to pull the conduit, making the vertically lowered conduit very unstable. Due to the long length of the conduit, once the posture is unstable and tilted, it is more difficult to correct.
[0006] The specific reason is that the lowered conduit cannot be effectively supported on the smooth vertical wall of the sewer, causing the conduit to tilt easily once the pull rope pulls the conduit. And because the wire runs through the bottom of the conduit, in order to avoid the conduit pressing on the wire, the conduit needs to be kept suspended, and the suspended conduit is more difficult to keep stable. During construction, the operator holds the conduit at the wellhead of the sewer and cannot loosen it. Obviously, this wire laying method is not only very clumsy, but also inefficient. Surveying and mapping construction often takes a long time, so this method causes great inconvenience in construction. Utility Model Content

[0008] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0022] The utility model has the following beneficial effects:
[0023] 1. During the working process, the operator squeezes the wheel arm inward to further reduce the spacing, and then puts it into the well. Under the elastic restoring force of the spring, the contact wheel elastically contacts and presses on the vertical wall of the well. The operator presses down the release tube. At this time, the contact wheel rolls against the vertical wall of the well. Under the elastic resistance force, the release tube is kept suspended by the friction between the well wall. When the surveying is completed, the operator pulls the release tube upward, and the floating ball or buoy tied to the wire of the release rises synchronously under the rolling of the contact wheel, and it is not easy to scratch the vertical wall during the rising process.
[0024] 2.

[0025] 3. During the working process, the operator pulls the wheel rod outward. At this time, the elastic wire wheels move away from each other. After the wire is passed through, the wheel rod is released. Under the restoring force of the telescopic spring, the elastic wire wheels move closer to each other until the guide limit is between the wheel grooves. When the float pulls the wire, the elastic wire wheel rotates under the friction force to protect the wire. This method can prevent the wire from scratching the bottom pipe opening of the wire release tube.
[0026] 4. The device disclosed by the utility model has a simple structure, is lightweight, has high flexibility, is easy to carry and move, and can be used in sewer wells of different specifications during construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Example 1
[0039] like Figure 1-6 As shown, a mobile surveying and laying-out equipment comprises a laying-out tube 1, on which an elastic wheel mechanism is threadedly connected and abuts against the inner wall of a sewer well 8. The elastic wheel mechanism is used to keep the laying-out tube 1 elastically abutting against the vertical wall of the sewer well 8 during construction, so as to keep the laying-out tube 1 suspended and prevent the guide inserted into the laying-out tube 1 from rubbing against the well wall.
[0040] Specifically, the elastic wheel-resisting mechanism includes an adjusting seat 2 threadedly connected to the wire-releasing tube 1, and a plurality of elastic contact wheel assemblies are hinged on the adjusting seat 3. The elastic contact wheel assembly includes a wheel arm rod 2 (the hinged manner is: a hinge interface is provided on the adjusting seat 3, and the inner end of the wheel arm rod 3 is hinged in the hinge interface through a fixed pin shaft), and the lower end of the wheel arm rod 3 is rotatably connected to a contact wheel 31 (the wheel axle of the contact wheel 31 is rotatably connected to the wheel arm rod 3).
[0041] At the same time, the elastic contact wheel 31 assembly also includes an elastic structure for adjusting the resistance force of the contact wheel 31, the elastic structure includes a long sliding opening 32 opened on the wheel arm rod 3, the outer wall of the wire-releasing tube 1 is fixedly connected with a horizontal rod 4 slidably connected to the long sliding opening 32, the horizontal rod 4 is sleeved with a spring 41, the outer end of the spring 41 freely resists the side wall of the wheel arm rod 3 (the outer wall of the wire-releasing tube 1 is fixedly connected with a spring seat, the inner end of the horizontal rod 4 is fixedly connected to the spring seat, and the inner end of the spring 41 is fixedly connected to the spring seat), and the outer end of the horizontal rod 4 is threadedly connected with a pushing nut for pushing the wheel arm rod 3.
[0042] During the working process, firstly, the spacing between the wheel arm rods 3 is adjusted according to the diameter of the vertical wall of the sewer 8, and the spacing is ensured to be slightly larger than the diameter of the vertical wall. During the adjustment process, the operator pushes the push nut into the wheel arm rod 3 to compress the spring 41 (during the compression of the spring 41, the outer end of the spring 41 slides against the wheel arm rod 3). During this process, the horizontal rod 4 slides relatively in a long sliding mouth 32 of a certain length. After adjusting to the target spacing, the operator squeezes the wheel arm rod 3 inward to further reduce the spacing, and then puts it into the sewer 8. Under the elastic restoring force of the spring 41, the contact wheel 31 elastically contacts and presses on the vertical wall of the sewer 8, and the operator presses down the release tube 1. At this time, the contact wheel 31 rolls against and rolls on the vertical wall of the sewer 8. Under the elastic resistance force, the release tube 1 is kept suspended by the friction between the well wall.
[0043] At the same time, in order to increase the friction force, the contact wheel 31 is made of elastic rubber material.
[0044] When the surveying is completed, the operator pulls the line-release tube 1 upwards, and the floating ball or buoy hung by the line-released wire is synchronously raised under the rolling of the contact wheel 31, and it is not easy to scratch the vertical well wall during the rising process.
[0045] Example 2
[0046] like Figure 1-6As shown, based on the structure of Example 1, when the water flow velocity in the water well 8 is relatively high, in order to prevent the wire from pulling the pay-off tube 1 carrying the contact wheel 31 to roll and fall, the upper end of the pay-off tube 1 is fixedly connected with an umbrella-shaped bracket structure; the umbrella-shaped bracket structure includes a plurality of pairs of ear plates 5 fixedly connected to the pay-off tube 1, and movable pins are hinged between the ear plates 5, and a diagonal support rod 51 is fixedly connected to the movable pin, and locking nuts are respectively threadedly connected to both ends of the movable pin.
[0047] The diagonal support rod 51 is tilted and supported to form an umbrella-shaped support structure, and after being supported around the edge of the wellhead of the sewer well 8, the locking nut is locked and squeezed onto the ear plate, so that the active pin shaft is kept in position by the squeezing force of the nut. In this way, the wire release tube 1 is stably kept in a suspended position.
[0048] Example 3
[0049] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 2, the wire passes through the upper end of the wire pay-off tube 1 and then the lower end. In order to prevent the wire from scratching the bottom tube opening of the wire pay-off tube 1, a wire wheel mechanism is assembled and connected at the lower end of the tube cavity of the wire pay-off tube 1 (near the tube opening).
[0050] Specifically, the wire wheel mechanism includes an elastic wire wheel 72 symmetrically arranged on both sides, and a wheel groove is provided on the elastic wire wheel 72. At the same time, the elastic wire wheel 72 is fixedly connected to a wheel rod 71 slidably connected to the wire pay-off tube 1 (specifically, the elastic wire wheel 72 is rotatably connected to a wheel frame, and the wheel frame is fixedly installed with the wheel rod 71), and the outer side of the wheel rod 71 is sleeved with a telescopic spring 73 (the inner end of the telescopic spring 73 is fixedly connected to the outer side wall of the wire pay-off tube 1), and the outer end of the wheel rod 71 is fixedly connected to a spring end seat 731, and the outer end of the telescopic spring 73 is fixedly connected to the spring end seat 731.
[0051] During operation, the operator pulls the wheel rod outward, and the elastic wire wheels 72 move away from each other. After the wire is passed through, the wheel rod is released, and the elastic wire wheels 72 move closer to each other under the restoring force of the telescopic spring 73 until the guide limit is between the wheel grooves. When the float pulls the wire, the elastic wire wheel 72 rotates under the friction force to protect the wire.
[0052] Example 3
[0053] like Figure 1-6 As shown, based on the structure of embodiment 3, the bottom of the above-mentioned line-release pipe 1 is equipped with a supporting mechanism supported in the mud of the sewer well 8. The whole device is supported at the bottom of the vertical well of the sewer well 8 by the supporting mechanism.
[0054] Specifically, the support mechanism includes a support seat 61, and a plurality of support rods 62 are hinged at the bottom of the support seat 61 (a hinge slot is provided at the bottom of the support seat 61, and the support rods 62 are hinged on a pin shaft fixed in the hinge slot), and a support cone rod 63 is fixedly connected at the bottom of the support rod 62 (to facilitate embedding into the mud). A plurality of long mounting screws installed at the bottom of the line-release tube 1 are fixedly connected at the top of the support seat 61. The support cone rod 63 is opened until the support cone rod 63 contacts the edge of the hinge slot. Under the action of gravity, the support rods 62 and the support cone rod 63 always maintain an outward inclined supporting posture, so as to support the entire device in this way, and at the same time, the line-release tube 1 is kept at a distance from the bottom of the well to prevent the wire from entering the mud at the bottom of the well.
[0055] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
