Description

Technical Field

[0001] This application relates to the field of steel sleeves, and particularly to a positioning device for embedded steel sleeves. Background Art

[0002] Steel sleeves are mainly used in construction, chemical industry, iron and steel, tap water, sewage treatment, etc., and are applicable to buildings where the pipeline passes through the wall without bearing pipeline vibration and telescopic deformation. In the electromechanical installation project, the traditional construction method for embedded combined steel risers requires first embedding PVC sleeves, then pulling out the PVC sleeves, and then embedding steel sleeves and plugging and stuffing.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects. After the PVC sleeves are processed and embedded, they need to be pulled out first and then the steel sleeves are embedded for the second time. The overall construction process is rather cumbersome, and the second embedding of the steel sleeves is prone to leakage at the pipe orifice, increasing the plugging construction cost. Summary of the Invention

[0004] In order to improve the above problems, this application provides a positioning device for embedded steel sleeves.

[0005] A positioning device for embedded steel sleeves provided by this application adopts the following technical solutions:

[0006] A positioning device for embedded steel sleeves includes a base, a vertical rod, and a horizontal rod. The vertical rod is fixedly connected to the base, the vertical rod and the horizontal rod are fixedly connected, there are multiple vertical rods and horizontal rods, and the multiple horizontal rods are arranged in a staggered manner. A first baffle and a second baffle are provided on the vertical rod. Waist-shaped holes are formed on both the first baffle and the second baffle. Telescopic rods are slidably connected to both the first baffle and the second baffle. The telescopic rods are in contact with the steel sleeve. Control rods are provided on both the first baffle and the second baffle. The control rods slide in the waist-shaped holes. One end of the control rod is fixedly connected to a control plate, and the control plate is in contact with the steel sleeve. Control nuts are threadedly connected to the control rods, and the control nuts are in contact with both the first baffle and the second baffle. Connecting rods are welded to the steel sleeve.

[0007] By adopting the above technical solutions, after the operator moves the telescopic rod to a preset position and places the steel sleeve, making the telescopic rod in contact with the steel sleeve, rotate the control nut to adjust the sliding of the control rod in the waist-shaped hole, so that the control rod drives the control plate to move until the control plate is in contact with the steel sleeve. The steel sleeve is relatively fixed under the combined action of the telescopic rod and the control plate. Then, fix another steel sleeve in the same operation method, and weld the connecting rods on the two steel sleeves to make the two steel sleeves relatively fixed. Move the two relatively fixed steel sleeves to the installation position. There is no need to first embed PVC sleeves. The overall operation process is relatively simple, reducing the possibility of leakage at the pipe orifice and improving the working efficiency of embedding the steel sleeve.

[0008] Preferably, slide rails are fixedly connected to both the first baffle and the second baffle. One end of the telescopic rod is fixedly connected with a sliding block, and the sliding block is located inside the slide rail for sliding. First positioning holes are formed in the slide rail, and second positioning holes are formed in both the first baffle and the second baffle. The first positioning holes and the second positioning holes are communicated with each other. A fixing bolt is provided on the sliding block, and the fixing bolt passes through the first positioning hole and the second positioning hole and is threadedly connected to the sliding block.

[0009] By adopting the above technical solution, when the operator moves the telescopic rod, the movement of the telescopic rod drives the movement of the sliding block inside the slide rail. When the telescopic rod moves to a preset position, the fixing bolt is passed through the first positioning hole and the second positioning hole and is threadedly connected to the sliding block. The fixing bolt limits the sliding block, so that the sliding block and the slide rail are positioned relative to each other, thereby making the telescopic rod and both the first baffle and the second baffle relatively positioned, which is convenient for positioning the steel casing before embedding the steel casing.

[0010] Preferably, an auxiliary rod is fixedly connected to the sliding block, an auxiliary hole is formed in the slide rail, and the auxiliary rod is located inside the auxiliary hole for sliding. An auxiliary coil spring is provided on the auxiliary rod. One end of the auxiliary coil spring is fixedly connected to the auxiliary rod, and the other end is fixedly connected to an auxiliary scale. A mating rod is fixedly connected to the telescopic rod, and one end of the auxiliary scale is fixedly connected to the mating rod.

[0011] By adopting the above technical solution, when the sliding block slides inside the slide rail, the sliding of the sliding block drives the sliding of the auxiliary rod, so that the auxiliary rod slides inside the auxiliary hole. When the sliding block slides, the telescopic rod expands and contracts. When the telescopic rod extends, the telescopic rod drives the mating rod to move, so that the mating rod pulls the auxiliary scale. The operator can adjust the movement of the sliding block inside the slide rail according to the scale on the auxiliary scale, and since the telescopic rod abuts against the steel casing, the distance between the two steel casings can be controlled, improving the accuracy of positioning the steel casing; when the sliding block slides to shorten the telescopic rod, the auxiliary scale automatically retracts under the action of the auxiliary coil spring, which is convenient for storing the auxiliary scale.

[0012] Preferably, a control coil spring is provided inside the sliding block. One end of the control coil spring is fixedly connected to the sliding block, and the other end is fixedly connected to a control rope. A mating block is fixedly connected to the telescopic rod, and one end of the control rope is fixedly connected to the mating block.

[0013] By adopting the above technical solution, when the sliding block slides to extend the telescopic rod, the telescopic rod drives the matching block to move, so that the matching block pulls the control rope to move. When the sliding block slides to a preset position, the fixing bolt is screwed in to relatively position the sliding block within the slide rail. When the fixing bolt is screwed out, the control rope applies a pulling force to the matching block under the action of the control coil spring, making the telescopic rod tend to shorten, which facilitates the operator to control the movement of the sliding block within the slide rail and improves the working efficiency of steel casing positioning.

[0014] Preferably, both the first baffle and the second baffle are hinged to the vertical rod. A positioning block is fixedly connected to the vertical rod. A positioning groove is formed in the positioning block for the first baffle and the second baffle to be inserted into. A positioning bolt is arranged on the positioning block, and the positioning bolt passes through the groove wall of the positioning groove and is threadedly connected to both the first baffle and the second baffle.

[0015] By adopting the above technical solution, when it is necessary to position the steel casing, both the first baffle and the second baffle are inserted into the positioning groove, and the positioning bolt passes through the groove wall of the positioning groove and is threadedly connected to both the first baffle and the second baffle, so that both the first baffle and the second baffle are relatively positioned with the vertical rod, facilitating the positioning work of the steel casing; when the positioning device needs to be stored, the positioning bolt is screwed out to release the limit of the positioning bolt on the first baffle and the second baffle, rotate the first baffle and the second baffle and insert them into the positioning groove of another positioning block, and then screw in the positioning bolt, reducing the space occupation cost of the first baffle and the second baffle and facilitating the storage of the positioning device.

[0016] Preferably, there are multiple first baffles and second baffles, and reinforcing ribs are fixedly connected between adjacent two first baffles and between adjacent two second baffles.

[0017] By adopting the above technical solution, due to the arrangement of the reinforcing ribs, the reinforcing ribs can improve the stability between adjacent two first baffles and second baffles, thereby improving the stability of the control rod, reducing the deformation of the first baffle or the second baffle caused by the control plate abutting against the steel casing, and improving the positioning accuracy of the steel casing.

[0018] Preferably, an annular block is fixedly connected to the base. An annular groove is formed in the annular block. A protective cover is detachably connected to the base. One end of the protective cover is inserted into the annular groove. A protective bolt is arranged on the protective cover. The protective bolt passes through the annular block and is threadedly connected to the protective cover. An auxiliary handle is fixedly connected to the protective cover, and a storage box is fixedly connected to the outer wall of the protective cover.

[0019] By adopting the above technical solution, when the device is stored, the operator screws out the control nut to place the control rod and the control plate separately. Rotate the first baffle and the second baffle upward and fix them. Insert one end of the protective cover into the annular groove, and pass the protective bolt through the annular block and thread it with the protective cover to position the protective cover and the base relative to each other. The protective cover can protect the vertical rod, the horizontal rod, the first baffle and the second baffle, reducing the corrosion or oxidation degree of the above parts. And the operator can pull the auxiliary handle to drive the base to move with the protective cover, facilitating the movement of the device; the storage box can be used to place the protective bolt or other parts.

[0020] Preferably, a fixing plate is fixedly connected between two adjacent vertical rods. The fixing plate is fixedly connected to the base and forms a placement groove for placing the connecting rod.

[0021] By adopting the above technical solution, when the steel sleeve is positioned at the preset position, the operator needs to weld the connecting rod on the outer walls of the two steel sleeves to position the two steel sleeves relative to each other. Due to the setting of the placement groove, the placement groove can be used for placing the connecting rod, facilitating the access of the connecting rod. And the setting of the fixing plate also strengthens the stability of multiple vertical rods.

[0022] Preferably, a reinforcing rod is fixedly connected to the fixing plate, and the reinforcing rod is fixedly connected to the base.

[0023] By adopting the above technical solution, the reinforcing rod can support the fixing plate, further improving the stability of the vertical rod, thereby enhancing the overall stability of the positioning device.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. Through the setting of the control rod, the control plate and the control nut, after the operator moves the telescopic rod to the preset position and places the steel sleeve, the telescopic rod abuts against the steel sleeve. Rotate the control nut to adjust the sliding of the control rod in the kidney-shaped hole, so that the control rod drives the control plate to move until the control plate abuts against the steel sleeve. The steel sleeve is relatively fixed under the combined action of the telescopic rod and the control plate. Then, fix the other steel sleeve in the same operation method, and weld the connecting rod on the two steel sleeves to make the two steel sleeves relatively fixed. Move the two relatively fixed steel sleeves to the installation position. There is no need to pre-bury the PVC sleeve first. The overall operation process is relatively simple, reducing the possibility of pipe orifice leakage and improving the working efficiency of steel sleeve pre-burial;

[0026] 2. Through the setting of the protective cover, when the device is stored, the operator screws out the control nut, places the control rod and the control board separately, rotates the first baffle and the second baffle upward and fixes them, inserts one end of the protective cover into the annular groove, and passes the protective bolt through the annular block and threads it with the protective cover, so that the protective cover and the base are positioned relative to each other. The protective cover can protect the vertical rod, the horizontal rod, the first baffle and the second baffle, reducing the degree of corrosion or oxidation of the above parts. Moreover, the operator can pull the auxiliary handle to drive the base to move with the protective cover, facilitating the movement of the device. Description of the Drawings

Detailed implementation manners

[0037] The following further describes the present application in detail with reference to the Figures 1-9 accompanying drawings.

[0038] An embodiment of the present application discloses a positioning device for a pre-embedded steel sleeve, as Figure 1 shown, including a base 1, a vertical rod 2 and a cross bar 3. There are four vertical rods 2 and four cross bars 3. The vertical rod 2 is fixedly connected to the base 1, the vertical rod 2 and the cross bar 3 are fixedly connected, and the four cross bars 3 are arranged in an intersecting manner.

[0039] As Figure 1 and 2 shown, a fixing plate 22 is fixedly connected between two adjacent vertical rods 2. There are four fixing plates 22. The fixing plate 22 is fixedly connected to the base 1 and forms a placement groove 23. A connecting rod 71 is welded on the steel sleeve 7, and the placement groove 23 can be used to place the unused connecting rod 71. A reinforcing rod 221 is fixedly connected to the fixing plate 22, and the reinforcing rod 221 is fixedly connected to the base 1. An annular block 11 is integrally formed on the base 1, and an annular groove 111 is formed in the annular block 11. A protective cover 6 is detachably connected to the base 1, and one end of the protective cover 6 is embedded in the annular groove 111. A protective bolt 61 is provided on the protective cover 6, and the protective bolt 61 passes through the annular block 11 and is threadedly connected to the protective cover 6. An auxiliary handle 62 is fixedly connected to the protective cover 6, and a storage box 63 is fixedly connected to the protective cover 6.

[0040] As Figure 3 , 4As shown in Figures 5 and 5, a first baffle 4 and a second baffle 5 are hinged to the vertical rod 2, and the length directions of the first baffle 4 and the second baffle 5 are perpendicular. Four positioning blocks 21 are fixedly connected to one vertical rod 2, and positioning grooves 211 are formed in the positioning blocks 21 for the first baffle 4 and the second baffle 5 to be inserted into. A positioning bolt 212 is arranged on the positioning block 21, and the positioning bolt 212 passes through the groove wall of the positioning groove 211 and is threadedly connected to both the first baffle 4 and the second baffle 5. Reinforcing ribs 46 are fixedly connected between adjacent first baffles 4 and between second baffles 5. The positioning groove 211 can limit the first baffle 4 and the second baffle 5, and after the first baffle 4 and the second baffle 5 are inserted into the positioning groove 211, the positioning bolt 212 is screwed in so that both the first baffle 4 and the second baffle 5 are relatively positioned with respect to the vertical rod 2.

[0041] As Figure 3 , 6 and 7 show, telescopic rods 42 are slidably connected to both the first baffle 4 and the second baffle 5. There are two telescopic rods 42 between the first baffle 4 and the second baffle 5. One ends of the two telescopic rods 42 are fixedly connected and the length directions of the two telescopic rods 42 are perpendicular. One side of the telescopic rod 42 abuts against the outer wall of the steel sleeve 7. Slide rails 44 are fixedly connected to both the first baffle 4 and the second baffle 5 along their own length directions. One end of the telescopic rod 42 is fixedly connected with a sliding block 421, and the sliding block 421 is located inside the slide rail 44 and slides. First positioning holes 441 are formed in the slide rail 44 along its own length direction, and second positioning holes 45 are formed in both the first baffle 4 and the second baffle 5 along their own length directions. The first positioning holes 441 and the second positioning holes 45 are communicated. A fixing bolt 422 is arranged on the sliding block 421, and the fixing bolt 422 passes through the first positioning hole 441 and the second positioning hole 45 and is threadedly connected to the sliding block 421.

[0042] As Figure 6 , 7 , 8 and 9 show, an auxiliary rod 423 is fixedly connected to the sliding block 421. An auxiliary hole 442 is formed in the slide rail 44 along its own length direction, and the auxiliary rod 423 is located inside the auxiliary hole 442 and slides. An auxiliary coil spring 424 is arranged on the auxiliary rod 423. One end of the auxiliary coil spring 424 is fixedly connected to the auxiliary rod 423, and the other end is fixedly connected to an auxiliary scale 425. A mating rod 426 is fixedly connected to the telescopic rod 42, and one end of the auxiliary scale 425 is fixedly connected to the mating rod 426. A control coil spring 427 is arranged inside the sliding block 421. One end of the control coil spring 427 is fixedly connected to the sliding block 421, and the other end is fixedly connected to a control rope 428. A mating block 429 is fixedly connected to the telescopic rod 42, and one end of the control rope 428 is fixedly connected to the mating block 429.

[0043] As Figure 6 , 7, as shown in Figures 8 and 9, when the operator pulls the joint of the two telescopic rods 42, the sliding block 421 slides within the slide rail 44, and the sliding of the sliding block 421 can cause the telescopic rod 42 to elongate. The elongation of the telescopic rod 42 can cause the control rope 428 to elongate. Under the action of the control coil spring 427, the control rope 428 pulls the mating block 429, causing the sliding block 421 to slide towards the vertical rod 2. The elongation of the telescopic rod 42 can cause the auxiliary scale 425 to elongate. When the scale elongates to a preset length, the fixing bolt 422 is passed through the first positioning hole 441 and the second positioning hole 45 and threadedly connected to the sliding block 421, so that the fixing bolt 422 limits the sliding block 421, thereby enabling the sliding block 421 to be relatively positioned within the slide rail 44. The steel sleeve 7 is placed between the two telescopic rods 42 and abuts against both telescopic rods 42, facilitating the subsequent positioning work of the steel sleeve 7.

[0044] As Figure 3 , 6 and 7 show that waist-shaped holes 41 are provided along the length directions of both the first baffle 4 and the second baffle 5, and control rods 43 slide relatively on both the first baffle 4 and the second baffle 5. The control rod 43 slides within the waist-shaped hole 41, and one end of the control rod 43 is fixedly connected to a control plate 431, and the control plate 431 abuts against the outer wall of the steel sleeve 7. Two control nuts 432 are threadedly connected to the control rod 43, and the two control nuts 432 abut against both the first baffle 4 and the second baffle 5. When the steel sleeve 7 abuts against the telescopic rod, the operator can rotate the control nut 432 to make the control rod 43 slide within the waist-shaped hole 41. The sliding of the control rod 43 can drive the sliding of the control plate 431. When the control plate 431 abuts against the steel sleeve 7, the two control nuts 432 are tightened to make the control rod 43 relatively positioned within the waist-shaped hole 41, thereby realizing the positioning of the steel sleeve 7.

[0045] The implementation principle of the positioning device for the embedded steel sleeve in the embodiment of the present application is as follows:

[0046] The operator pulls the telescopic rod 42 to extend the auxiliary scale 425 to the preset length, places the steel sleeve 7 between the two telescopic rods 42 and abuts against the telescopic rods 42, rotates the control nut 432 to drive the control rod 43 to drive the control plate 431 to move, and makes the control plate 431 abut against the steel sleeve 7 to realize the positioning of the steel sleeve 7. When the positioning of all the steel sleeves 7 is completed, connecting rods 71 are welded on the pipe walls of adjacent two steel sleeves 7 to mutually position the multiple steel sleeves 7 to form a sleeve group, facilitating the operator to move the sleeve group to the construction position.

[0047] The above are all the preferred embodiments of the present application. Without restricting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
