[0001] The utility model relates to the technical field of settlement observation, in particular to a steel structure settlement observation device. Background Technique

[0002] In order to master the settlement situation of a steel structure workshop, timely discover adverse subsidence phenomena, so as to take measures to ensure safe use, and at the same time provide data for reasonable design in the future, settlement observation is usually required. Settlement observation is to observe according to the observation points set on the building and the measuring points fixed (permanent level points), and measure the settlement degree and express it with data.

[0003] The utility model with the patent application number CN203241053U discloses a simple settlement observation point device for a steel structure workshop. This settlement observation point device is mainly composed of an observation point plate, connecting bolts and nuts. This observation point plate is an inverted ∟-shaped plate, that is, a right-angle bending plate. Bolt holes are opened on the upper horizontal plate of this observation point plate and connecting bolts with nuts are correspondingly installed. This observation point plate can be made of angle steel. The length of this observation point plate can be 50 mm. When in use, this observation point plate is welded on the side of the lower end section of the workshop steel column and is in an inverted ч shape, and at the same time, rust removal and anti-rust paint spraying are carried out. When measuring, the tower ruler is fixedly installed on the observation point plate with connecting bolts. The structure is simple, the cost is low, and it is practical and effective.

[0004] However, the above scheme lacks obvious observation positions and has low measurement accuracy; since the settlement observation points are not firm and exposed, they are easily damaged and knocked, and are prone to looseness, resulting in discontinuous and inaccurate settlement data, and unable to correctly reflect the true data of the building settlement, affecting the detection effect. For this reason, the utility model provides a steel structure settlement observation device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a steel structure settlement observation device to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a steel structure settlement observation device, including: a fixed groove, a protective cylinder and a second moving cylinder. The closed end of the protective cylinder is fixedly installed on one side of the fixed groove through bolts. A first moving cylinder is slidably connected inside the protective cylinder. A limiting plate is fixedly installed near the opening at the inner end of the protective cylinder.

[0007] One end of the second moving cylinder passes through the limiting plate and is slidably connected to the inner wall of the first moving cylinder. The front end and one side of the second moving cylinder are both open. An observation table is rotatably connected inside the second moving cylinder through a rotating shaft.

[0008] Preferably, the fixed groove is U-shaped, and fixing plates are fixedly installed at both the upper and lower ends of the side wall of one end of the fixed groove.

[0010] Preferably, a sliding plate is fixedly installed on an outer wall of the first moving cylinder. The outer wall of the sliding plate is slidably connected to the inner wall of the protective cylinder. A baffle is fixedly installed inside the port at the other end of the first moving cylinder. Two positioning grooves are formed at the upper ends of the first moving cylinder and the second moving cylinder.

[0011] Preferably, a positioning bolt is threadedly connected to the outer wall of the protective cylinder. One end of the positioning bolt passes through the side wall of the protective cylinder and is inserted into two of the positioning grooves.

[0012] Preferably, a sliding hole is formed in the side wall of the limiting plate. One end of the second moving cylinder slidably passes through the baffle and is inserted into the first moving cylinder. A sliding block is fixedly installed on the outer wall of one end of the second moving cylinder.

[0013] Preferably, the rotating shaft rotatably passes through the side wall of the second moving cylinder and is fixedly connected to one end of the observation platform.

[0024] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a steel structure settlement observation device, including: a fixed groove 2, a protective cylinder 4, and a moving cylinder II 11. The closed end of the protective cylinder 4 is fixedly installed on one side of the fixed groove 2 through bolts. The fixed groove 2 is U-shaped, and the fixed groove 2 is sleeved on the side wall of the steel structure building pile foundation 1 and welded. On the upper and lower ends of the side wall of one end of the fixed groove 2, fixing plates 3 are fixedly installed. On the upper and lower sides of the closed end of the protective cylinder 4, connecting plates 5 are fixedly installed. Fixing holes 6 are opened on the side walls of the connecting plates 5 and the fixing plates 3. The connecting plate 5 is inserted between the two fixing plates 3, and one end of the bolt passes through the fixing holes 6 on the fixing plate 3 and the connecting plate 5 and is threadedly connected to a nut, and it is fixed by the bolt.

[0025] A moving cylinder I 7 is slidably connected inside the protective cylinder 4. A limiting plate 15 is fixedly installed near the opening at the inner end of the protective cylinder 4. A sliding hole 16 is opened on the side wall of the limiting plate 15. The size of the sliding hole 16 is smaller than the size of the moving cylinder I 7. The limiting plate 15 plays a role of limiting and blocking the moving cylinder I 7. A sliding plate 8 is fixedly installed on the outer wall of the moving cylinder I 7. The outer wall of the sliding plate 8 is slidably connected to the inner wall of the protective cylinder 4. When the moving cylinder I 7 moves inside the protective cylinder 4, the sliding plate 8 slides on the inner wall of the protective cylinder 4.

[0026] A baffle is fixedly installed inside the port at the other end of the moving cylinder I 7. Two positioning grooves 9 are opened on the upper side of the moving cylinder I 7 and the moving cylinder II 11. A positioning bolt 10 is threadedly connected to the outer wall of the protective cylinder 4. One end of the positioning bolt 10 passes through the side wall of the protective cylinder 4 and is inserted into the positioning grooves 9 on the moving cylinder I 7 and the moving cylinder II 11 to fix the moving cylinder I 7 and the moving cylinder II 11.

[0027] One end of the moving cylinder II 11 slides through the sliding hole 16 and the baffle and is inserted into the moving cylinder I 7. A slider 12 is fixedly installed on the outer wall of one end of the moving cylinder II 11. The slider 12 is slidably connected to the inner wall of the moving cylinder I 7.

The rotating shaft 14 passes through the damping bearing and the side wall of the moving cylinder II 11 and is fixedly connected to one end of the observation platform 13. When the moving cylinder II 11 is pulled out of the protective cylinder 4, the observation platform 13 can be rotated out.

[0028] When the device is working and measurement is required, turn the positioning bolt 10 away from the positioning groove 9, then pull the second moving cylinder 11 outwards until the slider 12 contacts the baffle plate, and drive the first moving cylinder 7 to move outwards so that one end of the first moving cylinder 7 contacts the limiting plate 15. At this time, the positioning grooves 9 on the first moving cylinder 7 and the second moving cylinder 11 are communicated. Then, screw the positioning bolt 10 downwards until it is inserted into the two positioning grooves 9. Then, turn the observation platform 13 out of the outside of the second moving cylinder 11, place the measuring instrument on the observation platform 13 for measurement. After the measurement is completed, turn the observation platform 13 back into the second moving cylinder 11. Finally, push the second moving cylinder 11 and the first moving cylinder 7 back into the protective cylinder 4 and fix them.
