[0050] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0051] The following further details the present application with reference to the accompanying drawings of the specification.

[0052] The embodiment of the present application discloses a positioning device for a prefabricated grouting sleeve.

[0053] Such as Figure 1 And Figure 2As shown, the grouting sleeve includes a first grouting sleeve 41 and a second grouting sleeve 42, and the first grouting sleeve 41 and the second grouting sleeve 42 are arranged opposite to each other.

[0054] A positioning device for an assembled grouting sleeve includes a first connection component 1, a second connection component 2, and a distance adjustment component 3. The first connection component 1 is arranged on one of the grouting sleeves of the first grouting sleeve 41; the second connection component 2 is arranged on the second grouting sleeve 42; the distance adjustment component 3 is located between two adjacent grouting sleeves of the first grouting sleeve 41 and the second grouting sleeve 42. The first connection component 1 and the second connection component 2 are respectively movably arranged on the distance adjustment component 3. The first connection component 1 moves in the direction of approaching or departing from the grouting sleeve provided with the second connection component 2, and the second connection component 2 moves in the direction of departing from or approaching the direction of the first connection component 1. The distance adjustment component 3 is used to adjust the distance between two adjacent grouting sleeves.

[0055] When positioning two grouting sleeves, the distance adjustment component 3 is adjusted so that the first connection component 1 and the second connection component 2 move on the distance adjustment component 3, so that the first connection component 1 and the second connection component 2 move in the approaching or departing direction, thereby realizing that the distance between the two grouting sleeves can be freely adjusted to meet the distance requirements required by the design, and solving the problem that the distance between two adjacent existing grouting sleeves cannot be freely adjusted.

[0056] The distance adjustment component 3 includes an adjustment housing 31 and an adjustment gear 32.

[0057] An accommodation space is formed in the adjustment housing 31, the adjustment gear 32 is arranged in the accommodation space, and the adjustment gear 32 is rotatably arranged in the accommodation space.

[0058] The first connection component 1 and the second connection component 2 are respectively inserted through the adjustment housing 31 and respectively engage with the adjustment gear 32.

[0059] The first connection component 1 includes a first connecting rod 11 and a first fixing member 12.

[0060] The first fixing member 12 is arranged on the first grouting sleeve 41. One end of the first connecting rod 11 is arranged on the first fixing member 12, and the other end is inserted through the adjustment housing 31. One side of the first connecting rod 11 engages with the adjustment gear 32.

[0061] The second connection component 2 includes a second connecting rod 21 and a second fixing member 22.

[0062] The second fixing member 22 is arranged on the second grouting sleeve 42. One end of the second connecting rod 21 is arranged on the second fixing member 22, and the other end is inserted through the adjustment housing 31. The side of the second connecting rod 21 facing the first connecting rod 11 engages with the adjustment gear 32.

[0063] The first connecting rod 11 and the second connecting rod 21 are arranged in parallel.

[0064] Specifically, both the first grouting sleeve 41 and the second grouting sleeve 42 are cylindrical sleeves.

[0065] The first fixing member 12 is sleeved on the barrel of the first grouting sleeve 41, and the second fixing member 22 is sleeved on the barrel of the second grouting sleeve 42.

[0066] To enhance the stability of the connection between the first fixing member 12 and the first connecting rod 11, one end of the first fixing member 12 and the first connecting rod 11 are welded.

[0067] To enhance the stability of the connection between the second fixing member 22 and the second connecting rod 21, one end of the second fixing member 22 and the second connecting rod 21 are welded.

[0068] The shape of the adjustment housing 31 is adjusted to be a cube as a whole. The adjustment gear 32 is arranged in the accommodation space. The adjustment gear 32 is respectively rotatably connected to the inner walls of the adjustment housing 31 on both sides, so that the adjustment gear 32 can rotate in the accommodation space.

[0069] The adjustment housing 31 is respectively provided with a first through hole and a second through hole. The first through hole and the second through hole respectively penetrate through opposite sides of the adjustment housing 31, and the first through hole and the second through hole are arranged in parallel.

[0070] In this embodiment, the first through hole is arranged above the adjustment gear 32, and the second through hole is arranged below the adjustment gear 32.

[0071] The first connecting rod 11 and the second connecting rod 21 respectively pass through the first through hole and the second through hole;

[0072] The first connecting rod 11 is located above the adjustment gear 32, and the second connecting rod 21 is located below the adjustment gear 32. Teeth are arranged on the side of the first connecting rod 11 facing the adjustment gear 32 and the side of the second connecting rod 21 facing the adjustment gear 32. The first connecting rod 11 and the second connecting rod 21 are respectively meshed with the adjustment gear 32 through the teeth.

[0073] When the adjustment gear 32 rotates, since the first connecting rod 11 and the second connecting rod 21 are respectively meshed with the adjustment gear 32 up and down, the first connecting rod 11 and the second connecting rod 21 move relatively, causing the first connecting rod 11 and the second connecting rod 21 to move closer to or away from each other.

[0074] Moreover, since the first connecting rod 11 is connected to the first grouting sleeve 41 through the first fixing bracket, and the second connecting rod 21 is connected to the second grouting sleeve 42 through the second fixing bracket, the first grouting sleeve 41 and the second grouting sleeve 42 can move closer to or away from each other, thereby achieving the purpose of adjusting the distance between the first grouting sleeve 41 and the second grouting sleeve 42.

[0075] Furthermore, the first connecting rod 11 is inserted through the first through hole, a first limiting groove is provided on the hole wall of the first through hole, and a first limiting block is provided on the first connecting rod 11 and is in embedded fit with the first limiting groove.

[0076] The second connecting rod 21 is inserted through the second through hole, a second limiting groove is provided on the hole wall of the second through hole, and a second limiting block 211 is provided on the second connecting rod 21 and is in embedded fit with the second limiting groove.

[0077] Among them, the first limiting groove is a dovetail groove, and the dovetail grooves are provided on the side walls on both sides of the first through hole.

[0078] The first limiting block is a dovetail tenon matching the dovetail groove on the first limiting groove, and the dovetail tenons are provided on the side walls on both sides of the first connecting rod 11.

[0079] Similarly, the second limiting groove is a dovetail groove, and the dovetail grooves are provided on the side walls on both sides of the second through hole.

[0080] The second limiting block 211 is a dovetail tenon matching the dovetail groove on the second limiting groove, and the dovetail tenons are provided on the side walls on both sides of the second connecting rod 21.

[0081] The setting of the dovetail groove and the dovetail tenon limits the sway when the first connecting rod 11 moves on the first through hole and the second connecting rod 21 moves on the second through hole, so that the first connecting rod 11 and the second connecting rod 21 can only move linearly along the first through hole and the second through hole, ensuring the stability of the meshing between the first connecting rod 11 and the adjusting gear 32 and the stability of the meshing between the second connecting rod 21 and the adjusting gear 32.

[0082] The distance adjustment assembly 3 includes a rotating member 33, the rotating member 33 passes through the adjustment housing 31 and is connected to the adjustment gear 32, and the rotating member 33 is used to drive the adjustment gear 32 to rotate.

[0083] The rotating member 33 passes through the adjustment housing 31 and is coaxially connected to the adjustment gear 32.

[0084] Specifically, the rotating member 33 includes a rotating rod 331 and a rotating cap 332. One end of the rotating rod 331 passes through the adjustment housing 31 and is fixedly connected to the adjustment gear 32. The rotating rod 331 is coaxially connected to the adjustment gear 32. The rotating cap 332 is arranged at the other end of the rotating rod 331. The shape of the rotating cap 332 is generally cylindrical, and the cross-sectional diameter of the rotating cap 332 is larger than that of the rotating rod 331. And to increase the friction when the operator rotates the rotating cap 332, anti-slip patterns are provided on the side wall of the rotating cap 332.

[0085] The arrangement of the rotating member 33 facilitates the operator to rotate the adjustment gear 32 to conveniently adjust the distance between the first grouting sleeve 41 and the second grouting sleeve 42.

[0086] The first fixing member 12 and the second fixing member 22 are respectively detachably connected to the corresponding grouting sleeves of the first grouting sleeve 41 and the second grouting sleeve 42.

[0087] Such as Figure 1 and Figure 2 As shown in the figure, in one implementation manner of the embodiment of the present application, the first fixing member 12 includes a first fixing clamping plate 121 and a first fastening member 122. There are two first fixing clamping plates 121, and the first grouting sleeve 41 is arranged between the two first fixing clamping plates 121.

[0092] There are at least two second fastening members 222, and at least two second fastening members 222 are arranged on both sides of the grouting sleeve.

[0093] Specifically, the first fastening member 122 includes a first clamping portion 1211 and a first fixing portion 1212. The shape of the first clamping portion 1211 is arc-shaped, and the inner diameter of the arc of the first clamping portion 1211 is equal to the outer diameter of the grouting sleeve of the first grouting sleeve 41.

[0094] There are two first clamping portions 1211, and the two first clamping portions 1211 are respectively arranged at both ends of the first fixing portion 1212. The first fastening member 122 is screwed to the first clamping portion 1211.

[0095] The second fastener 222 includes a second clamping portion 2211 and a second fixing portion 2212. The shape of the second clamping portion 2211 is arc-shaped, and the inner diameter of the arc of the second clamping portion 2211 is equal to the outer diameter of the second grouting sleeve 42.

[0096] There are two second clamping portions 2211, and the two second clamping portions 2211 are respectively arranged at both ends of the second fixing portion 2212. The second fastener 222 is screwed to the second clamping portion 2211.

[0097] The shapes of the first fixing clamp plate 121 and the second fixing clamp plate 221 are both "Ω" - shaped. There is a screw hole provided on the first clamping portion 1211 at both ends of the first fixing portion 1212, and there is a screw hole respectively provided on the second clamping portion 2211 at both ends of the second fixing portion 2212.

[0098] The two first fixing clamp plates 121 are arranged opposite to each other to clamp the first grouting sleeve 41 therebetween, and the screw holes on the first clamping portions 1211 on the same side of the two first fixing clamp plates 121 are coaxially arranged. Then, the first fasteners 122 are respectively screwed into the screw holes on both sides of the first grouting sleeve 41 to realize the clamping and fixing of the first grouting sleeve 41 by the two first fixing clamp plates 121.

[0099] Similarly, the two second fixing clamp plates 221 are arranged opposite to each other to clamp the second grouting sleeve 42 therebetween, and the screw holes on the second clamping portions 2211 on the same side of the two second fixing clamp plates 221 are coaxially arranged. Then, the second fasteners 222 are respectively screwed into the screw holes on both sides of the second grouting sleeve 42 to realize the clamping and fixing of the second grouting sleeve 42 by the two second fixing clamp plates 221.

[0100] It should be noted that the first connecting rod 11 and the second connecting rod 21 are respectively welded to one of the first fixing portion 1212 and the second fixing portion 2212.

[0101] Furthermore, elastic buffer pads are provided on the side of the first fixing portion 1212 in contact with the first grouting sleeve 41 and the side of the second fixing portion 2212 in contact with the second grouting sleeve 42 to prevent the first fixing member 12 from damaging the outer surface of the first grouting sleeve 41 and the second fixing member 22 from damaging the outer surface of the second grouting sleeve 42. Among them, the elastic buffer pad can be made of materials such as rubber that have buffer and shock absorption properties and good service life performance.

[0102] The first connecting rod 11 and the second connecting rod 21 are both located in the plane where the line connecting the centers of the two grouting sleeves, namely the first grouting sleeve 41 and the second grouting sleeve 42, is located.

[0103] Specifically, the plane where the line connecting the centers of the first grouting sleeve 41 and the second grouting sleeve 42 is located is the central axis plane of the whole of the first grouting sleeve 41 and the second sleeve.

[0104] Since in actual operation, the first grouting sleeve 41 will be stacked above the second grouting sleeve 42, the first connecting rod 11 and the second connecting rod 21 being located on the central axis plane can make the overall force balanced, preventing the positioning device for the assembled grouting sleeve from being broken or bent by the component force of the gravity of the first grouting sleeve 41 during the process of adjusting the distance between the first grouting sleeve 41 and the second grouting sleeve 42.

[0110] The first elastic member 124 is located between the two first force-applying portions 1232.

[0111] The shape of the first clamping portion 1211 is arc-shaped.

[0112] When the first fixing member 12 needs to be installed on the first grouting sleeve 41, two first force - applying portions 1232 are pressed simultaneously, the first elastic member 124 is compressed, and two third clamping portions 1231 open, facilitating the placement of the first grouting sleeve 41 between the two third clamping portions 1231. Then, no force is applied to the two first force - applying portions 1232, and the first elastic member 124 pushes the first force - applying portions 1232 on both sides under the action of elastic potential energy, and the two third clamping portions 1231 clamp the first grouting sleeve 41.

[0113] The second clamping plate 223 includes a fourth clamping portion 2231 and a second force - applying portion 2232.
