Description

Technical Field

[0001] This utility model relates to the field of pre-embedded sleeve positioning technology, and in particular to a rapid positioning device for pre-embedded sleeves. Background Technology

[0002] The steel plate is processed into a standard wing ring according to the outer diameter of the pre-embedded sleeve. The wing ring is then welded to half of the pre-embedded sleeve. It should be noted that double-sided full welding should be used during welding to ensure that the pre-embedded sleeve and the wing ring can be tightly connected together.

[0003] To ensure the stable installation of embedded sleeves under current conditions, it is important to use soft materials to seal the embedded sleeves at the basement's exterior wall exit point. Additionally, during the prefabrication of embedded sleeves, one end should be welded and sealed with a high-quality steel plate. This sealing steel plate should only be removed after the embedded sleeve installation is complete. For example, CN212428085U discloses a rapid and precise positioning device for embedded sleeves. Its positioning mechanism is used to fix the embedded sleeve, a laser alignment mechanism is used to measure the direction and distance of the embedded sleeve's horizontal movement, and an adjustment mechanism adjusts the position of the embedded sleeve based on the direction and distance measured by the laser alignment mechanism. This device has a simple structure and is easy to operate, enabling precise positioning and fixing of the embedded sleeve. However, the placement of the embedded sleeve is not a one-step process, requiring multiple position adjustments. Existing positioning devices cannot fix the embedded sleeve, especially in the horizontal and vertical directions, making it difficult to adjust its position and ensuring accurate positioning. Utility Model Content

[0007] Preferably, the load-bearing base is rotatably mounted with a drive shaft via a damping bearing, and a notch is provided in the side wall of the guide sleeve. A guide rod is integrally provided inside the bottom end of the guide sleeve and rotatably fitted in the steering sleeve. The drive shaft and the steering sleeve are respectively keyed to a meshing drive gear and a driven gear.

[0008] Preferably, the steering sleeve is fitted with a first cylinder that is fixedly connected to the lifting sleeve.

[0009] Preferably, a second cylinder is fixedly installed on the steering sleeve, and a lifting slider fixedly connected to the output end of the second cylinder is slidably mounted on the steering sleeve.

[0010] Preferably, the clamping mechanism includes a third cylinder fixedly installed in the telescopic bracket, and a telescopic rod fixedly connected to the output end of the third cylinder is slidably fitted in the telescopic bracket. Lifting brackets that are movably pulled by the telescopic rod are vertically slidably fitted in both the upper and lower ends of the telescopic bracket.

[0011] Preferably, a second connecting rod is pin-connected between the telescopic rod and the lifting bracket, and a locking screw for fixing the clamping plate is threaded in the lifting bracket.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model utilizes a load-bearing base with a hollow guide sleeve, and a steering sleeve driven to rotate by a drive shaft is set in the guide sleeve. By setting a lifting sleeve in the steering sleeve, a horizontally telescopic bracket can be set in the lifting sleeve, so that the limiting mechanism can be adjusted in the horizontal direction.

A guide rod 8 is integrally provided in the bottom end of the guide sleeve 2 and is rotatably fitted in the steering sleeve 3. The drive shaft 6 and the steering sleeve 3 are respectively keyed with a meshing drive gear 9 and a driven gear 10. The guide sleeve 2 and the guide rod 8 provide horizontal guidance and limit for the steering sleeve 3. Under the driving action of the drive shaft 6, the steering sleeve 3 rotates in the horizontal direction, thereby facilitating the position adjustment of the pre-embedded sleeve.

[0021] The steering sleeve 3 is fitted with a vertically lifting sleeve 4, and a horizontally telescopic bracket 5 is fitted with a sliding sleeve 4. See the instruction manual for details. Figure 1 With appendix Figure 2 A second cylinder 12 is fixedly installed on the steering sleeve 3, and a lifting slider 13, which is fixedly connected to the output end of the second cylinder 12, is slidably mounted on the steering sleeve 3. A first connecting rod 14 is pin-connected between the lifting slider 13 and the telescopic bracket 5. Under the combined action of the first cylinder 11 and the second cylinder 12, the lifting sleeve 4 reciprocates vertically along the steering sleeve 3 to facilitate height adjustment according to the depth of the pre-embedded sleeve.

[0022] The telescopic bracket 5 is fixedly equipped with a clamping mechanism for fixing the pre-embedded sleeve. Please refer to the instruction manual for details. Figure 2The clamping mechanism includes a third cylinder 15 fixedly installed in the telescopic bracket 5, and a telescopic rod 16 fixedly connected to the output end of the third cylinder 15 is slidably mounted in the telescopic bracket 5.

Clamping plates 19 for clamping the pre-embedded sleeve from the front and rear sides are slidably installed in the lifting brackets 17. According to the depth of the pre-embedded sleeve, the height of the two lifting brackets 17 is adjusted under the driving action of the third cylinder 15 so as to limit and fix the upper and lower ends of the pre-embedded sleeve.

[0023] The steering sleeve 3 is fitted with a first cylinder 11 that is fixedly connected to the lifting sleeve 4.

[0024] A second connecting rod 18 is pin-connected between the telescopic rod 16 and the lifting bracket 17, and a locking screw for fixing the clamping plate 19 is threaded in the lifting bracket 17, thereby ensuring that the position of the clamping plate 19 is fixed and that the pre-embedded sleeve is stably clamped.

[0025] It should be noted that the specific model and specifications of the cylinder need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0026] The functional principle of this utility model can be explained through the following operation methods:

[0027] The drive shaft 6 is controlled to rotate on the load base 1, and the drive gear 9 and driven gear 10 are used to drive the steering sleeve 3 to rotate horizontally, so that the lifting sleeve 4, the telescopic bracket 5 and the limiting mechanism rotate synchronously.

[0028] The first cylinder 11 and the second cylinder 12 are opened on the steering sleeve 3, so that the lifting sleeve 4 is raised and lowered vertically, so that the telescopic bracket 5 and the limiting mechanism can move up and down synchronously.

[0029] The second cylinder 12 is opened by controlling the lifting sleeve 4, and the telescopic bracket 5 is driven to extend and retract horizontally through the first connecting rod 14 so that the limiting mechanism extends and retracts synchronously.

[0030] The third cylinder 15 is opened on the telescopic bracket 5, and the two lifting brackets 17 are moved in opposite directions through the second connecting rod 18 to correspond to the upper and lower ends of the pre-embedded sleeve.

[0031] The clamping plate 19 is moved on the lifting bracket 17 to clamp and limit the upper and lower ends of the pre-embedded sleeve.
