Description

Technical Field

[0001] This utility model relates to the field of concrete placing machine technology, specifically an electric concrete placing machine for building construction. Background Technology

[0002] An electric concrete placing boom is a construction equipment used in conjunction with a concrete pump. It is driven by an electrical control system, which drives the motor to operate components such as the screw conveyor. At the same time, the hydraulic system controls the extension, folding, and rotation of the boom, transporting concrete from the storage hopper to the designated location for placement. This can greatly improve placement efficiency and reduce labor intensity.

[0003] An investigation revealed a Chinese utility model patent (Publication No.: CN217840912U) disclosing an electric concrete placing boom for intelligent building construction. The boom includes a cylindrical support column, outriggers, a boom, a horizontal pipe, and a lifting pipe. An auxiliary adjustment mechanism is located between the horizontal pipe and the lifting pipe, at the lower end of the boom. This mechanism includes a first L-shaped support plate, a second L-shaped support plate, a connecting pipe, a first gear, a drive motor, and a second gear. Belonging to the field of building construction, this auxiliary adjustment mechanism, driven by the drive motor, rotates the connecting pipe via the first gear, allowing for 360-degree adjustment of the lifting pipe at its bottom. This replaces manual movement, facilitating the user to move the lifting pipe to a designated position. Combined with a protective mechanism, it buffers and reduces vibrations generated by the concrete placing boom, preventing damage to building structures.

[0004] Although the aforementioned patent improves the working surface of the hanging pipe and increases the efficiency of concrete placement by setting up an auxiliary adjustment mechanism and cooperating with the drive motor, the second gear, and the connecting pipe to rotate the position of the hanging pipe through the rotation of the drive motor, the concrete itself has a certain weight during the conveying process, and the pump body also has a certain impact force when pumping concrete. All of these will have a certain impact force on the hanging pipe during placement. Since the hanging pipe is not equipped with a tie device, it is more likely to become unstable and overturn during the placement process due to excessive concrete impact force, which poses a certain safety hazard and is not conducive to improving the safety of operators.

[0005] Therefore, this utility model provides an electric concrete placing machine for building construction to solve the above problems. Utility Model Content

[0017] (III) Beneficial Effects

This assembly has a simple structure, is highly practical, and significantly improves the safety and stability of the concrete placing boom during operation, increasing the operator's efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides an electric concrete placing boom for building construction, such as... Figures 1-5 As shown, an electric concrete placing boom for construction engineering includes a truss 1, a limiting frame 2 is fixedly connected to the lower bottom end of the truss 1, a discharge pipe 3 is fixedly connected inside the limiting frame 2, and a tie assembly is provided at the lower bottom end of the discharge pipe 3.

[0028] The outer wall of the discharge pipe 3 is rotatably sleeved with a main gear 4. The bottom end of the main gear 4 is fixedly connected with a rotating sleeve 5. The inner wall of the rotating sleeve 5 is fixedly connected with a hanging pipe 6. The tie assembly includes a retainer 7 fixedly connected to the top of the limit frame 2. The inside of the retainer 7 is fixedly connected with a drive motor 8. The output end of the drive motor 8 is fixedly sleeved with a reciprocating screw 9. The outer wall of the reciprocating screw 9 is threaded with a tie block 10, and the tie block 10 slides on the outer wall of the hanging pipe 6. The top end of the truss 1 is fixedly connected with a winch 11. The output end of the winch 11 is wound with a steel strand 12. The outer wall of the tie block 10 is provided with a groove, and the steel strand 12 slides inside the groove.

[0029] A stepper motor 13 is fixedly connected to the lower end of the limit frame 2. A drive tooth 14 is fixedly sleeved at the output end of the stepper motor 13. The drive tooth 14 meshes with the main gear 4. A cylindrical support column 15 is fixedly connected to the lower end of the truss 1.

[0030] The end of the reciprocating screw 9 is fixedly connected to a limit ball 23, and the steel strand 12 is fixedly connected to a stop plate at one end of the limit ball 23.

[0031] Specifically, by setting up a tie assembly, sufficient tie force can be provided to the lifting pipe 6 when the concrete placing machine is working, ensuring its stability during concrete impact and preventing the placing machine from becoming unstable and overturning due to the large impact force of pumped concrete. The rotation of the drive motor 8 causes the reciprocating screw 9 connected to its output end to rotate accordingly, thereby adjusting the position of the tie block 10 according to the placing distance, so that the steel strand 12 can better tie the lifting pipe 6. When the tie block 10 is moved to the designated position, the winch 11 is started to work, winding the steel strand 12, and then the baffle at the end of the steel strand 12 ties the tie block 10, thereby tying the lifting pipe 6 and preventing it from falling due to its own weight or concrete impact. When it is necessary to adjust the placing angle, the stepper motor 13 is started, causing the drive gear 14 connected to its output end to drive the main gear 4 to rotate, thereby rotating the lifting pipe 6, increasing the placing range, reducing the labor intensity of operators, and improving the concrete placing efficiency.

[0032] A connecting sleeve 16 is fixedly sleeved on the side wall of the cylindrical support column 15, a support frame 17 is fixedly connected to the outer side wall of the connecting sleeve 16, and an installation block is fixedly connected to the bottom end of the support frame 17.

A sliding wheel is rotatably connected to the inner wall of the positioning frame 18. A support assembly is provided at the top of the truss 1.

[0034] The support assembly includes a fixing block 20 fixedly connected to the top of the truss 1, and the fixing block 20 is wrapped around the outer wall of the discharge pipe 3. A vertical frame 21 is fixedly connected to the top of the truss 1, and a steel cable 22 is fixedly connected to the top of the vertical frame 21. The end of the steel cable 22 is fixedly connected to the top of the truss 1.

[0035] Specifically, the connecting sleeve 16 and support frame 17 on the side wall of the cylindrical support column 15 can provide sufficient support for the placing machine to ensure its stability during placing. The mounting block can quickly and stably connect with the bearing surface. The positioning frame 18 at the top of the truss 1 can reduce the friction of the steel strand 12 during winding by using the inner rotating roller 19 and sliding wheel, thereby improving the winding efficiency. The height difference also provides sufficient stability for the steel strand 12 during winding.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
