Description

Technical Field

[0001] This application relates to the field of building construction, and particularly to a lifting device for a concrete conduit of an engineering pile. Background Art

[0002] In building construction, concrete is usually poured into engineering piles to provide support for buildings and ensure the overall stability of the buildings. During the pouring process of the engineering piles, a concrete conduit lifting device needs to be used in cooperation to lift the concrete conduit upward at a constant speed in the pile hole, thereby completing the pouring of the concrete engineering pile.

[0003] In the related art, Chinese Patent with the application number CN202221847280.6 proposed a lifting device for a concrete pouring conduit of a diaphragm wall, including a mounting frame, a hoist and a pulley assembly arranged on the mounting frame, a steel wire rope arranged on the hoist and cooperating with the pulley assembly, and a connecting hook arranged on the steel wire rope. By driving the hoist to pull the steel wire rope, through the transmission of the pulley assembly, the connecting hook connected to the concrete conduit is driven to move upward, thereby realizing the lifting of the concrete conduit.

[0004] When the above-mentioned concrete conduit lifting device is actually used, the construction workers usually use the method of manual vibration to discharge the air bubbles in the concrete, reduce the pores, make the concrete dense, and thus ensure the quality of the structure. However, manual vibration is time-consuming, laborious and cumbersome, and in the concrete pouring of engineering piles with a large length, it is difficult for construction workers to vibrate the concrete poured at the bottom of the pile hole by manual vibration. Summary of the Utility Model

[0005] In order to solve the problems of time-consuming, laborious and cumbersome manual vibration, this application provides a lifting device for a concrete conduit of an engineering pile, which has the advantages of labor-saving and simple operation, good vibration quality and wide operation range.

[0006] The lifting device for a concrete conduit of an engineering pile provided by this application adopts the following technical solutions:

[0007] A lifting device for a concrete conduit of an engineering pile includes a mounting frame, a concrete conduit for discharging concrete, a first winding mechanism for lifting the concrete conduit, a concrete vibrating mechanism for vibrating the concrete, and a second winding mechanism for lifting the concrete vibrating mechanism. The first winding mechanism is installed on the mounting frame, the concrete conduit is connected to the movable end of the first winding mechanism, the second winding mechanism is installed on the mounting frame, and the concrete vibrating mechanism is connected to the movable end of the second winding mechanism.

[0008] By adopting the above technical solution, the first winding mechanism is used to gradually pull up the concrete conduit from the bottom of the engineering pile, so that the engineering pile can be poured from bottom to top. At the same time, the second winding mechanism is used to synchronously pull up the concrete vibrating mechanism, and the concrete is vibrated while the engineering pile is being poured, so as to eliminate bubbles in the concrete and make the concrete poured denser. Compared with manual vibration, it is more labor-saving and more efficient. At the same time, the second winding mechanism can be used to vibrate the concrete in a larger range, which can meet the needs of pouring engineering piles of larger lengths. It has a wider range and is more applicable than manual vibration.

[0009] Optionally, the concrete vibrating mechanism includes a vibrating mounting piece and a vibrating rod for vibrating concrete, the vibrating mounting piece is sleeved on the concrete conduit, the vibrating rod is installed on the vibrating mounting piece, and the top of the vibrating mounting piece is connected to the second winding mechanism.

[0010] By adopting the above technical solution, the vibrating mounting piece is mounted on the concrete conduit, which makes it easier to pull up the vibrating rod and the concrete conduit synchronously, improves the accuracy of the coordination between the two, and further improves the vibration effect. At the same time, the vibrating rod is used to vibrate the concrete, which is easy to operate, has high vibration quality and high vibration efficiency, can ensure the quality of concrete pouring, and improve the density of concrete pouring.

[0011] Optionally, the vibrating mounting piece is provided with a pre-installed slot for installing a vibrating rod, an elastic limiting piece is provided in the pre-installed slot, the vibrating rod extends into the pre-installed slot, and the vibrating rod is clamped between the movable end of the elastic limiting piece and the side wall of the pre-installed slot.

[0012] By adopting the above technical solution, the vibrating rod can be inserted into the pre-installed slot by compressing the movable end of the elastic limiting member in the pre-installed slot, and then the movable end of the elastic limiting member is released to install the vibrating rod in the pre-installed slot. When disassembling, the vibrating rod can be taken out by compressing the movable end of the elastic limiting member again. Both installation and disassembly are very convenient, which improves the assembly efficiency at the construction site.

[0013] Optionally, the installation frame includes a support member and a mounting member, the mounting member is arranged on the top of the support member, the support member is provided with a lifting avoidance opening, and the first winding mechanism lifts or lowers the concrete conduit through the lifting avoidance opening.

[0014] By adopting the above technical solution, the lifting avoidance opening of the support is used to cooperate with the lifting of the concrete conduit, and there is no need to extend the first winding mechanism to the side of the support, so that the first winding mechanism and the concrete conduit are directly above or below the support, avoiding the installation frame from tipping over and improving the stability of the overall structure. Compared with extending the first winding mechanism to the side of the support, the above structure simplifies the installation structure and improves the on-site assembly efficiency.

[0015] Optionally, the first winding mechanism includes a first winch installed on a support member, a lifting plate installed on a mounting member, a first lifting rope connecting the first winch and the lifting plate, and a pulley for cooperation in lifting. The lifting plate is slidably engaged with the mounting member in the vertical direction. The pulley is installed at the top of the mounting member. One end of the first lifting rope is connected to the first winch, and the other end passes through the pulley and is connected to the top of the lifting plate. The concrete conduit is installed at the bottom of the lifting plate.

[0016] By adopting the above technical solution, the first lifting rope can be wound or unwound by driving the first winch, and then the lifting plate can be lifted or lowered through the pulley, thereby adjusting the height of the concrete conduit. Moreover, the winch is small in volume, light in weight and large in lifting capacity, and can ensure that the concrete conduit moves more linearly in cooperation with the rope.

[0017] Optionally, the second winding mechanism includes a second winch and a second lifting rope. The second winch is installed on the top of the lifting plate. The lifting plate is provided with a lifting cooperation port. One end of the second lifting rope is connected to the second winch, and the other end passes through the lifting cooperation port and is connected to the concrete vibrating mechanism.

[0018] By adopting the above technical solution, by installing the second winding mechanism on the lifting plate, driving the first winding mechanism can synchronously lift the concrete conduit and the concrete vibrating mechanism, which saves more energy compared with the second winding mechanism lifting the concrete vibrating mechanism alone, and the synchronism between concrete pouring and vibrating is better, resulting in a better concrete pouring effect. At the same time, the second winding mechanism can be used to accurately adjust the length of the vibrating rod inserted into the concrete, further improving the vibrating effect, and thus improving the pouring quality of the engineering pile.

[0019] Optionally, the mounting member includes two supporting vertical plates and a connecting plate. The two supporting vertical plates are vertically arranged on the top of the support member. The two ends of the connecting plate are respectively arranged on the tops of the two supporting vertical plates. On one side of the two supporting vertical plates close to each other, a sliding cooperation groove is opened in the vertical direction. The two ends of the lifting plate are provided with sliding cooperation blocks. The sliding cooperation blocks extend into the sliding cooperation groove and are slidably engaged with the sliding cooperation groove.

[0020] By adopting the above technical solution, the sliding cooperation between the sliding cooperation block and the sliding cooperation groove can limit the lifting plate in the horizontal direction, ensuring that the lifting plate moves in the vertical direction during the ascending and descending processes, improving the pouring accuracy of the concrete conduit and the vibrating accuracy of the vibrating rod, ensuring that the concrete is poured more densely, and thus enhancing the strength and stability of the engineering pile, providing a more stable support for the building.

[0021] Optionally, a hoisting fitting is provided at the top of the vibrating mounting member, and one end of the second hoisting rope away from the second winch is connected to the hoisting fitting.

[0022] By adopting the above technical solution, the second hoisting rope is connected to the vibrating mounting member by using the hoisting fitting. Driving the second winch can adjust the height of the vibrating rod through the hoisting fitting, optimizing the installation structure between the second hoisting rope and the vibrating mounting member and improving the assembly efficiency at the construction site.

[0023] Optionally, a plurality of support feet are provided at the bottom of the installation frame, and the height of the support feet is adjustable.

[0024] By adopting the above technical solution, by installing the support feet, the installation frame can adapt to an uneven installation surface. Adjusting the heights of different support feet can make the installation frame keep horizontal on an uneven or inclined surface, avoiding inclination and affecting the pouring process.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. By providing the concrete vibrating mechanism and the second winding mechanism, the concrete can be vibrated while the concrete conduit is being lifted for pouring, making the concrete pouring more dense, thereby improving the strength and reliability of the engineering pile; using the second winding mechanism to adjust the height of the concrete vibrating mechanism and vibrate the concrete is more efficient and labor-saving compared with manual vibration, and at the same time, the vibration range is larger, which can meet the pouring needs of engineering piles with larger lengths, and the applicable surface is wider than manual vibration;

[0027] 2. By using the pre-installed notch and the elastic limiting member, the convenient installation and disassembly of the vibrating rod can be realized. Compressing the movable end of the elastic limiting member can install and disassemble the vibrating rod, and after loosening the movable end of the elastic limiting member, the vibrating rod can be clamped between the movable end of the elastic limiting member and the side wall of the pre-installed notch, with convenient operation and stable structure, improving the installation efficiency at the construction site;

[0028] 3. By installing the second winding mechanism on the lifting plate, driving the first winch can drive the concrete conduit and the concrete vibrating mechanism to move simultaneously, saving more energy, and making the pouring of the concrete conduit and the vibration of the vibrating rod more synchronous, effectively improving the density of the concrete pouring; at the same time, the second winding mechanism can be used to accurately adjust the length of the vibrating rod inserted into the concrete, further improving the vibration effect.

Detailed implementation manners

[0035] The following further describes the present application in detail in conjunction with the attached Figures 1-5 drawings.

[0036] The embodiment of the present application discloses a lifting device for a concrete conduit of an engineering pile. Referring to Figure 1 , it includes an installation frame 1 and a first winding mechanism 2 for lifting the concrete conduit 00. The installation frame 1 is used to install the first winding mechanism 2. The concrete conduit 00 is connected to the movable end of the first winding mechanism 2. At the same time, the concrete conduit 00 is connected to an external concrete perfusion channel. Concrete enters the concrete conduit 00 from the external perfusion channel and flows into the engineering pile. At the same time, the first winding mechanism 2 is driven to uniformly lift the concrete conduit 00 upward from the bottom of the engineering pile, thereby completing the concrete pouring of the engineering pile from bottom to top.

[0037] Specifically, referring to Figure 1 and Figure 2 , the installation frame 1 includes an installation member 11 and a supporting member 12. The supporting member 12 has a cuboid structure and is used to provide support for the entire structure. The installation member 11 is arranged on the top of the supporting member 12 and is used to install and connect other components. At the same time, a plurality of supporting feet 13 are arranged at the bottom of the supporting member 12, and the supporting height of each supporting foot 13 can be adjusted separately to ensure that the supporting member 12 can be kept horizontal on an uneven surface.

[0038] Further, the mounting member 11 includes a connecting plate 111 and supporting vertical plates 112. There are two supporting vertical plates 112, which are respectively vertically mounted at two corners of the supporting member 12. The connecting plate 111 is horizontally mounted on the tops of the two supporting vertical plates 112. The two supporting vertical plates 112 and the connecting plate 111 form a U-shaped frame structure. The first winding mechanism 2 is mounted on the mounting member 11, and the concrete conduit 00 is hoisted inside the U-shaped structure of the mounting member 11. In this embodiment, the mounting member 11 is an integrally formed structure.

[0039] In addition, at the corresponding position of the concrete conduit 00 on the supporting member 12, that is, between the two supporting vertical plates 112, a lifting avoidance opening 121 is provided for the movement of the concrete conduit 00 in cooperation, ensuring that when the first winding mechanism 2 lifts the concrete conduit 00, the concrete conduit 00 and the first winding mechanism 2 will not have a position conflict with the supporting member 12.

[0040] Further, referring to Figure 1 and Figure 2 , the first winding mechanism 2 includes a lifting plate 21 for hoisting and connecting the concrete conduit 00, a first winch 22 for lifting the lifting plate 21, a first lifting rope 23 connecting the first winch 22 and the lifting plate 21, and a pulley 24 cooperating with the first lifting rope 23. The first winch 22 is mounted on the top of the supporting member 12 and on one side of the mounting member 11. The lifting plate 21 is slidably mounted between the two supporting vertical plates 112. The pulley 24 is mounted on the bottom of the connecting plate 111. One end of the first lifting rope 23 is wound around the first winch 22, and the other end passes through the pulley 24 and is connected to the lifting plate 21. Driving the first winch 22 can wind the first lifting rope 23, pull up the lifting plate 21, and further lift the concrete conduit 00 hoisted on the lifting plate 21 to pour the engineering pile from bottom to top.

[0041] At the same time, vertically arranged sliding fit grooves 113 are provided on the side walls of the two supporting vertical plates 112 close to each other, and sliding fit blocks 25 are formed at both ends of the lifting plate 21 close to the supporting vertical plates 112. The sliding fit blocks 25 extend into the sliding fit grooves 113 and are slidably fitted in the vertical direction. When the first winch 22 winds the first lifting rope 23, the lifting plate 21 moves upward, and at the same time, the sliding fit blocks 25 slide in the sliding fit grooves 113 in the vertical direction. By means of the limiting effect of the sliding fit grooves 113 on the sliding fit blocks 25, it is ensured that the lifting plate 21 moves up and down in the vertical direction, thereby improving the stability of the movement of the concrete conduit 00.

[0042] Referring to Figure 1 and Figure 3, a lifting device for a concrete conduit of an engineering pile disclosed in an embodiment of the present application further includes a concrete vibrating mechanism 4 and a second winding mechanism 5. The concrete vibrating mechanism 4 is installed on the concrete conduit 00, and the second winding mechanism 5 is installed on the lifting plate 21 and connected to the concrete vibrating mechanism 4. The height of the concrete vibrating mechanism 4 can be adjusted by using the second winding mechanism 5. The concrete vibrating mechanism 4 is used to vibrate the concrete during the pouring process of the engineering pile, thereby reducing the pores of the concrete and making the concrete pouring more dense. Moreover, in cooperation with the second winding mechanism 5, the concrete can be vibrated within a large height range, and the working range is better than manual vibration.

[0043] Further, referring to Figure 3 and Figure 4 , the concrete vibrating mechanism 4 includes a vibrating mounting member 41 for installing various components and a vibrating rod 42 for vibrating the concrete. The vibrating mounting member 41 has an annular structure and is slidably sleeved on the side wall of the concrete conduit 00. The vibrating rod 42 is inserted through the vibrating mounting member 41. In this embodiment, four vibrating rods 42 are provided and evenly distributed on the vibrating mounting member 41.

[0044] At the same time, referring to Figure 1 and Figure 4 , a hoisting fitting 43 is provided at the top of the vibrating mounting member 41. The hoisting fitting 43 has an annular structure and is fixed to the vibrating mounting member 41. The movable end of the second winding mechanism 5 is connected to the hoisting fitting 43. Driving the second winding mechanism 5 can drive the vibrating mounting member 41 to move up and down through the hoisting fitting 43, thereby adjusting the length of the vibrating rod 42 inserted into the concrete.

[0045] When the first winding mechanism 2 lifts the concrete conduit 00 and pours the concrete, the second winding mechanism 5 is simultaneously driven to adjust the lifting of the vibrating mounting member 41. While pouring the concrete, the length of the vibrating rod 42 inserted into the concrete is adjusted, and the vibrating rod 42 is used for vibration to improve the density of the concrete pouring.

[0046] Further, referring to Figure 3 and Figure 4 , a pre-installation slot 44 for installing the vibrating rod 42 is formed through the vibrating mounting member 41. The pre-installation slot 44 is a waist-shaped hole with a length direction along the radial direction of the vibrating mounting member 41, and the vibrating rod 42 is inserted through the pre-installation slot 44. At the same time, an elastic limiting member 45 is provided in the pre-installation slot 44. The outer shell of the elastic limiting member 45 is installed on the side wall of the pre-installation slot 44 close to the concrete conduit 00. The movable end of the elastic limiting member 45 extends to the other side of the pre-installation slot 44, and the vibrating rod 42 is clamped between the movable end of the elastic limiting member 45 and the side wall of the pre-installation slot 44. In this embodiment, four pre-installation slots 44 are formed corresponding to the four vibrating rods 42, and four elastic limiting members 45 are provided.

[0047] During specific installation, the movable end of the compression elastic limiting member 45 is compressed, and the vibrating rod 42 is inserted into the pre-installed notch 44. Subsequently, the movable end of the elastic limiting member 45 can press the vibrating rod 42 tightly within the pre-installed notch 44. When it is necessary to disassemble the vibrating rod 42, hold the vibrating rod 42 and squeeze the elastic limiting member 45 to make the movable end of the elastic limiting member 45 contract towards the inside of the housing, and then the vibrating rod 42 can be taken out. Using the elastic limiting member 45 to fix the vibrating rod 42 makes both installation and disassembly very convenient, improving the assembly efficiency at the construction site.

[0048] Furthermore, referring to Figure 3 and Figure 5 , the second winding mechanism 5 includes a second winch 51 and a second lifting rope 52. The second winch 51 is installed on the top of the lifting plate 21. At the same time, a lifting cooperation port 26 is penetrated through the corresponding position of the lifting plate 21. The second lifting rope 52 passes through the lifting cooperation port 26, and one end is connected to the second winch 51, and the other end is connected to the lifting cooperation member 43 at the top of the vibrating installation member 41. In this embodiment, there are two sets of the second winch 51 and the second lifting rope 52, and two lifting cooperation ports 26 are correspondingly provided and two lifting cooperation members 43 are provided.

[0049] Driving the second winch 51 to wind the second lifting rope 52 can lift the vibrating installation member 41, and further lift the vibrating rod 42. By controlling the second winch 51, the length of the vibrating rod 42 inserted into the concrete can be flexibly adjusted, improving the vibrating effect of the vibrating rod 42 and ensuring the compactness of the concrete pouring.

[0050] The implementation principle of an engineering pile concrete conduit lifting device disclosed in an embodiment of the present application is as follows: Before use, first set up the installation frame 1 at the location of the engineering pile to be poured, and adjust the support feet 13 to keep the support member 12 horizontal. Lift the concrete conduit 00 under the lifting plate 21 and connect it to the external concrete pouring channel. Subsequently, install the vibrating rod 42 on the vibrating installation member 41 and put the vibrating installation member 41 on the concrete conduit 00. Then connect the lifting cooperation member 43 to the second lifting rope 52. Subsequently, the first winch 22 can be driven to lower the concrete conduit 00 to the bottom of the engineering pile. Subsequently, pour the concrete and lift the concrete conduit 00. At the same time, the second winch 51 can be driven to adjust the length of the vibrating rod 42 inserted into the concrete, and vibrate the concrete while pouring.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
