Description

Technical Field

[0001] The present application relates to the technical field of safety monitoring construction in hydropower projects, and in particular to a connecting rod locking device for protecting the orifice of an inclined hole. Background Art

[0002] Inclinometer holes are suitable for use within soil slopes and retaining structures in large-scale projects such as water conservancy and hydropower projects and subway excavations. They consist of a drilled hole and an inclinometer tube, typically made of ABS engineering plastic or aluminum alloy. The tubes are connected using a convex-concave groove and secured with self-tapping screws. The inclinometer tubes contain two mutually perpendicular guide grooves at 90° and 180° for orienting the inclinometer probe. This ensures lightweight, robustness, corrosion resistance, and a twist-free guide groove. The inclinometer tubes can be combined with inclinometer probes to monitor deep horizontal displacement in dams, slopes, excavations, foundations, piles, cofferdams, and other structures. Various types of hole protection devices are installed at the openings of the inclinometer holes to prevent damage and the ingress of foreign matter.

[0003] At present, there are various types of orifice protection devices for inclinometer holes. Generally, a protection device without a locking function or a conventional lock or hexagon socket screw lock is used for protection on the side of a steel pipe or steel cover. Although conventional locks and hexagon socket screw locks can play the functions of opening and locking, the disadvantages are that different keys must be carried, the opening and closing speed is slow, and it is not convenient to use.

[0027] In response to the above problems, an embodiment of the present application provides a connecting rod lock inclinometer hole opening protection device. The technical solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The connecting rod lock inclinometer hole opening protection device shown includes a connecting rod lock 5 and further includes:

[0029] The steel casing 1 is configured in a cylindrical shape, specifically a circular shape, and is placed over the opening of the inclinometer tube 2 for protection. The inner wall of the steel casing 1 is provided with a locking rod retaining ring 7, a steel cover 3, a lock body mounting hole 4, a connecting rod 8, a connecting rod bracket 9, a pull rod plate 10, and connecting bolts 11.

[0030] In this device, the connecting rod lock 5 is fixedly set in the lock body mounting hole 4, and the movable part of the tail of the connecting rod lock 5 is fixedly connected to the pull rod piece 10. The connecting rod 8 is rotatably connected to the pull rod piece 10 through the connecting bolt 11. The connecting rod 8 is slidably set on the connecting rod bracket 9, and the connecting rod bracket 9 is fixedly set on the steel protective cover 3. The steel protective cover 3 is covered on the steel casing 1 and abuts against the top of the lock rod retaining ring 7, so that the connecting rod lock 5 makes the connecting rod 8 inserted under the lock rod retaining ring 7 when the lock is opened or closed.

[0031] In this way, the connecting rod lock 5 drives the pull rod piece 10 to rotate, thereby driving the connecting rod 8 to slide on the connecting rod bracket 9, so that the connecting rod 8 can move in and out or detach from the bottom of the lock rod retaining ring 7 to achieve locking; at the same time, the lock rod retaining ring 7 is used as a support and placement platform for the steel protective cover 3 to place the steel protective cover 3. When in use, only the steel protective cover 3 is rotated to embed it into the steel casing 1 and then the key is selected to achieve protective locking. It is convenient and quick to use.

[0032] In one embodiment, since the thickness of the steel cover 3 should not be too thick, the length of the connecting rod lock 5 during installation will cause its bottom to extend longer, so that the connecting rod 8 will be away from the locking rod retaining ring 7 after connection. Therefore, the pull rod sheet 10 is set to be groove-shaped so that the connection between the connecting rod 8 and the connecting bolt 11 is as close as possible to the bottom of the locking rod retaining ring 7. The connecting rod 8 is in a horizontal position and is just below the locking rod retaining ring 7. In this way, after the connecting rod 8 is inserted under the locking rod retaining ring 7, the gap between the two is small, and the steel cover 3 is locked firmly.

[0033] In one embodiment, the connecting rod bracket 9 is surface mounted, and is configured to be an inverted U-shape, with slots on both sides thereof for the connecting rod 8 to pass through. The connecting rod bracket 9 is fastened with screws below the steel cover 3 .

[0034] In one embodiment, to protect the connecting rod lock 5 and extend its service life, the lock body mounting hole 4 is configured as a stepped hole. The connecting rod lock 5 is fastened to the lock body mounting hole 4 by screws. A protective cover 6 is embedded in the top of the lock body mounting hole 4 to cover the top of the connecting rod lock 5. The protective cover 6 can be a rubber cover with a handle. After the connecting rod lock 5 is locked, it is inserted into the lock body mounting hole 4 to cover the entire lock body mounting hole 4.

[0035] In one embodiment, a specific device is manufactured as follows: the steel casing 1 is machined from a galvanized steel pipe with a height of 100 mm, an outer diameter of 140 mm, and a thickness of 2 mm. The steel cover 3 is cut into a circular shape from a galvanized steel plate with a diameter of 136 mm and a thickness of 2 mm. The lock rod retaining ring 7 is bent into a circular shape from a 5 mm diameter steel bar. The lock body of the connecting rod lock 5 is a finished MS705 straight lock with a lock head outer diameter of 28 mm and a height of 18 mm. The square head at the lower end of the lock core has a side length of 7.5 mm and is equipped with a special "I"-shaped key. The lock body has a rounded hole with a side length of 20 mm through the center of the steel cover 3 as the lock body mounting hole 4. The rounded hole has a diameter of 22 mm. The pull rod piece 10 is a finished 403 steel galvanized pull rod piece with a length of 43 mm, a connecting rod hole diameter of 4 mm, a connecting rod hole spacing of 34 mm, and a fixing hole side length of 8 mm. The bending height is 4 mm. The connecting rod bracket 9 is machined from an aluminum alloy plate with a length of 84mm, a width of 22mm, and a thickness of 2mm. The bent ends are 15mm high, with a 6mm diameter hole in the middle of the bend. The connecting rod 8 is a factory-customized steel connecting rod with a diameter of 5mm and a length of 51mm. The connecting bolt 11 connecting the connecting rod 8 to the tie rod plate 10 is a national standard stainless steel part with a length of 15mm and a diameter of M3. Furthermore, the handle 12 is made of a stainless steel eyebolt with an M8 thread diameter and a length of 14mm. The eyebolt has an outer diameter of 34mm, an inner diameter of 20mm, and a ring diameter of 7mm. The lower portion is made of a finished 304 stainless steel rivet nut with an outer diameter of 11mm, a cap thickness of 1.5mm, and an overall length of 18mm.
