Description

Technical Field

[0001] The utility model relates to the technical field of formwork installation, in particular to a conical sleeve pipe extraction device. Background Technique

[0002] In building construction projects, during the formwork support process according to construction requirements, wall-through bolts are needed to reinforce the formwork. In the early stage, plastic pipe sleeves were generally used to cover the bolts as protective sleeves for wall-through bolts. However, due to the soft material of the pipe sleeves, they were easily damaged and lacked support force, so they were gradually phased out. With the development of technology, aluminum membranes have been widely used in building construction projects, and the sleeves have been updated. Currently, conical sleeves mainly made of ABS raw materials are mainly used. The conical sleeves made of this material have high strength and toughness, which can avoid the situation of mortar leakage. Moreover, the conical sleeves made of ABS raw materials can be reused more than 50 times, greatly reducing the overall project cost. The main function of the conical sleeve is to be used together with the wall-through bolt, for the connection between the inner and outer formworks of the wall, to bear the lateral pressure of the concrete and other loads, and to ensure that the distance between the inner and outer formworks can meet the design requirements. In addition, the conical sleeve can replace traditional PVC pipes and cement supports, and the size control is more accurate, and the wall aesthetics is better.

[0003] However, it is rather difficult to take out and recycle these sleeves after the concrete pouring is completed. Although there are special disassembly tools provided on the market, these tools are usually made of carbon steel. When in use, the tool is fitted with the small end of the conical pipe, and then a hammer is used to strike, so that the sleeve is evenly stressed and thus taken out from the concrete. This operation method is likely to cause damage to the sleeve and the concrete, and it is unsafe for personnel to operate on the external scaffold, and it is time-consuming and laborious.

[0004] Therefore, it is necessary to develop a conical sleeve pipe extraction device to solve the above problems. Content of the Utility Model

The first gear 14 meshes with the third gear 16. The second end of the second connecting shaft is connected to the output end of the power device. The structural design of the gear set mainly considers the need for high torque output. The size of the third gear 16 needs to be smaller than that of the first gear 14. The specific size is determined according to the force required to pull out the conical sleeve 35 and the output force of the motor 25.

[0056] In some embodiments, as Figure 7 and 8 and 9 and 11 shown, the conical sleeve 35 pipe taking device further includes a battery 24, a motor 25, and a convex groove pulley 17. The second end of the second connecting shaft is connected with a concave groove pulley 29. The rotating shaft 23 of the motor 25 is connected with the convex groove pulley 17. The convex groove pulley 17 is engaged with the concave groove pulley 29. The motor 25 is installed on the outer wall of the housing 11. The battery 24 is installed at the tail of the motor 25, and the battery 24 is electrically connected to the motor 25. In some embodiments, the conical sleeve 35 pipe taking device further includes a two-way power switch 28. The two-way power switch 28 is connected in the connection loop between the battery 24 and the motor 25 for controlling the power supply of the battery 24 to the motor 25.

The hand crank 30 can be used as an emergency replacement when the motor 25 fails to work.

[0061] After all components are assembled, charge the battery 24 or connect the motor 25 directly to the mains. After the formwork is removed, insert the first circular tube 6 at the front end of the device into the hole in the tapered sleeve 35, so that the tail end of the steel sheet 3 extends beyond the outer edge of the tapered sleeve 35. Press the elastic block 20 located in the first clamping hole 32. Under the rebound force of the first spring 7, the tip 2 of the second circular tube 9 extends to push the two steel sheets 3 apart until the block 4 is in close contact with the inner wall of the first circular tube 6. At this time, the elastic block 20 is clamped into the second clamping hole 33 (the tail end of the second circular tube 9 will not completely enter the tail end of the first circular tube 6 during the entire process. To move the elastic block 20 from the second clamping hole 33 to the first clamping hole 32, you only need to press the elastic block 20 and then pull the second circular tube 9 backwards). Hold the handle 21 with your right hand and press the third circular tube 10 with your left hand to support the concrete surface. Check whether the device is perpendicular to the concrete surface and other conditions. After ensuring that there are no errors, start the motor 25 or crank the hand crank 30, the gear set rotates, and then drives the rack 13 to move, the rack 13 drives the first circular tube 6 to move backward, the first circular tube 6 drives the second circular tube 9 and the steel sheet 3 to move backward to achieve the backward pulling of the tapered sleeve 35, and finally pull the tapered sleeve 35 out of the concrete wall 34; during the pulling out process of the tapered sleeve 35, the second spring 18 is compressed. After the tapered sleeve 35 is completely pulled out, the power acting on the gear set is disconnected, and the posture of the entire device is reset under the action of the second spring 18.

[0062] In this solution, workers do not need to climb the external scaffold to take the pipes, and there is no need to damage the conical sleeve 35 and the concrete by hammering or the like. The operation process saves time and effort, and the efficiency is increased by about 60% compared with the traditional solution.

[0063] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
