[0025] Example 1

[0026] like Figures 1-4 As shown, a lifting device for electromechanical installation construction includes a lifting equipment body 1. The lifting equipment body 1 includes a personnel carrying mechanism 2 and a material carrying mechanism 4. The personnel carrying mechanism 2 is composed of a main base 201, a main lifting mechanism 3 and a personnel carrying platform 202. The main lifting mechanism 3 is installed on the main base 201.

[0027] The material handling mechanism 4 consists of a secondary base 401, a secondary lifting mechanism 5, and a material chamber 6. The secondary lifting mechanism 5 is installed inside the secondary base 401 and consists of a secondary motor 501, a worm gear 502, a worm 503, a telescopic rod 504, and a material platform 505. The secondary motor 501 is connected to the worm 503. The bottom of the telescopic rod 504 is fixedly connected to the worm gear 502. The worm 503 and the worm gear 502 are rotatably connected. The top of the worm 503 is fixedly connected to the material platform 505.

[0028] This embodiment of the equipment is mainly divided into two functional modules: the personnel carrying mechanism 2 and the material handling mechanism 4. These two modules operate independently yet work in concert, suitable for the simultaneous needs of personnel operation and material transportation in electromechanical installation scenarios (such as pipeline and equipment installation). The personnel carrying mechanism 2 is responsible for safely transporting construction personnel to the working height. Its composition and functions are as follows: Main base 201: As the basic support component of the personnel carrying mechanism 2, it bears the weight of the entire personnel carrying module (including the main lifting mechanism 3 and the personnel on the personnel platform 202), ensuring stability during personnel transport; Main lifting mechanism 3, mounted on the main base 201, is the core power component driving the lifting of the personnel platform 202, moving the platform 202 up and down through extension or lifting actions; Personnel platform 202: A platform for construction personnel to stand or operate, connected to the main lifting mechanism 3, and its height is adjusted according to the movement of the main lifting mechanism 3 to meet the operational needs of personnel at different work positions;

[0029] Material handling mechanism 4 focuses on the lifting and transportation of construction materials (such as pipelines, fittings, tools, etc.). Its core is the auxiliary lifting mechanism 5, and its specific structure and working principle are as follows: Material handling mechanism 4 consists of an auxiliary base 401, an auxiliary lifting mechanism 5, and a material chamber 6. The auxiliary lifting mechanism 5 is installed inside the auxiliary base 401 and is the power core for material lifting. The transmission logic of the auxiliary lifting mechanism 5 is as follows: The auxiliary lifting mechanism 5 achieves the lifting and lowering of the material platform 505 through a transmission chain of auxiliary motor 501 → worm gear 503 → worm wheel 502 → telescopic rod 504 → material platform 505. The specific coordination process is as follows: The auxiliary motor 501 provides power and directly drives the worm gear 503 to rotate (converting the power of the motor into the rotational motion of the worm gear 503); the worm gear 503 meshes with the worm wheel 502 (the worm gear 502 and worm gear 503 are mechanical...). The worm gear 503, a commonly used speed reduction and reversing component in transmission, drives the worm wheel 502 to rotate synchronously (power is transmitted through gear meshing, which can reduce the speed and increase the torque, making it suitable for driving heavier materials). The bottom of the telescopic rod 504 is fixedly connected to the worm wheel 502. Due to the rotation of the worm wheel 502 (usually the center of the worm wheel 502 is designed with an internal thread, and the corresponding position of the telescopic rod 504 is designed with an external thread), the rotation of the worm wheel 502 is converted into the linear extension and retraction motion of the telescopic rod 504 (that is, when the worm wheel 502 rotates, the telescopic rod 504 is driven to extend upward or retract downward through the thread engagement). The top of the telescopic rod 504 is directly fixedly connected to the material platform 505. When the extension and retraction of the telescopic rod 504 causes the overall height to change, the material platform 505 will rise and fall synchronously, ultimately realizing the vertical transportation of materials.

[0030] In this embodiment, the main lifting mechanism 3 comprises a main motor 301, a lead screw 302, a fixing block 304, a lifting frame 305, a connecting rod 303, and a slider 306. The main motor 301 is connected to the lead screw 302. The lifting mechanism 3 has multiple lifting frames 305, which are connected by the connecting rod 303. A slider 306 is provided in the middle of the connecting rod 303 on the bottom left side. The slider 306 is fixedly connected to the connecting rod 303, and the slider 306 is slidably connected to the lead screw 302. Two sets of fixing blocks 304 are provided on the right side of the main base 201 and the right side of the personnel carrier 2. The connecting rod 303 is connected to the fixing block 304. A railing 203 is installed above the personnel carrier platform 202. Sliding grooves 204 are opened on both sides inside the personnel carrier platform 202. The material chamber 6 is fixedly connected to the personnel carrier platform 202. A baffle 601 is installed on the side of the material chamber 6, and the material platform 505 passes through the material chamber 6.

[0031] The main lifting mechanism 3 consists of a main motor 301, a lead screw 302, a fixed block 304, a lifting frame 305, a connecting rod 303, and a slider 306. The main motor 301 drives the lead screw 302 to rotate, providing power for the entire mechanism. Multiple lifting frames 305 are connected by the connecting rod 303. This structural design allows multiple lifting frames 305 to work collaboratively, maintaining stability during lifting and preventing tilting or swaying. The slider 306 works in conjunction with the lead screw 302. A slider 306 is located in the middle of the connecting rod 303 on the bottom left side. The slider 306 is fixedly connected to the connecting rod 303, and there is a sliding connection between the slider 306 and the lead screw 302. When the main motor 301... When the lead screw 302 rotates, the rotational motion of the lead screw 302 is converted into the linear motion of the slider 306, thereby driving the entire lifting frame 305 system to achieve the lifting function; the connection between the fixed block 304 and the connecting rod 303 is provided by two sets of fixed blocks 304 on the right side of the main base 201 and the right side of the personnel carrying mechanism 2, respectively. The connecting rod 303 is connected to these fixed blocks 304. The function of the fixed blocks 304 is to provide a stable support point for the connecting rod 303, ensuring that the connecting rod 303 will not be displaced when subjected to force, thereby ensuring the structural stability of the entire lifting equipment;

[0032] The manned platform 202 is structurally designed with railings 203 installed on it. The main function of the railings 203 is to ensure the safety of operators and prevent falls from the platform. Additionally, sliding grooves 204 are provided on both sides of the interior of the manned platform 202. These sliding grooves 204 may be used for sliding cooperation with other components to achieve specific functions. Regarding the design of the material chamber 6, the material chamber 6 is fixedly connected to the manned platform 202. A baffle 601 is installed on the side of the material chamber 6 to prevent materials from falling out. A material platform 505 extends through the material chamber 6, facilitating the storage and retrieval of materials. Operators can use the material platform 505 to transport the required materials to the work position.

[0033] When using this utility model:

[0034] The height adjustment of the manned platform 202 is achieved through the transmission of the main lifting mechanism 3. The core is to convert the power of the main motor 301 into the vertical lifting motion of the manned platform 202.

[0035] Power input: The main motor 301 starts and outputs power to drive the lead screw 302 to rotate (transmitting the rotational motion of the motor to the lead screw 302); the slider 306 in the middle of the bottom left connecting rod 303 is slidably connected to the lead screw 302, and the slider 306 is fixed to the connecting rod 303. When the lead screw 302 rotates, the slider 306 performs linear reciprocating motion on the lead screw 302 (the rotational motion of the lead screw 302 is converted into the linear motion of the slider 306).

[0036] Lifting frame 305 linkage: Multiple lifting frames 305 are connected by connecting rods 303 to form a foldable and unfoldable frame structure. The linear movement of slider 306 drives the connecting rod 303 on the bottom left to move, thereby driving all lifting frames 305 to unfold or retract in coordination through the connecting rods 303 (similar to the principle of a scissor lift): When slider 306 moves to the right along lead screw 302, lifting frame 305 unfolds and the overall height increases; when slider 306 moves to the left along lead screw 302, lifting frame 305 retracts and the overall height decreases.

[0037] Lifting of the manned platform 202: The unfolding and retraction of the lifting frame 305 directly drives the synchronous lifting of the top manned platform 202, ultimately realizing the vertical transportation of construction personnel;

[0038] Safety protection: The railings 203 on the manned platform 202 prevent personnel from falling and ensure operational safety; the sliding grooves 204 inside the manned platform 202 can cooperate with other components (such as the material handling mechanism 4 related components) to ensure stability during coordinated movement;

[0039] The lifting principle of material mechanism 4 is as follows: Material mechanism 4 achieves the lifting of material platform 505 through the transmission of auxiliary lifting mechanism 5. The core is to utilize the speed reduction and torque amplification characteristics of worm gear transmission to convert the power of auxiliary motor 501 into the vertical transport motion of material platform 505. The specific process is as follows:

[0040] Power Input and Transmission: The auxiliary motor 501 starts, driving the worm gear 503 to rotate (converting the motor power into the rotational motion of the worm gear 503). Speed ​​Reduction and Torque Increase: The worm gear 503 meshes with the worm wheel 502 (the worm gear 502 and worm gear 503 transmission has speed reduction and reversing functions). The rotation of the worm gear 503 drives the worm wheel 502 to rotate synchronously. Through gear meshing, the speed is reduced and the torque is increased (suitable for driving heavier materials). Telescopic Rod 504 Extension and Retraction: The bottom of the telescopic rod 504 is fixedly connected to the worm wheel 502. The center is designed with an internal thread, and the corresponding position of the telescopic rod 504 is designed with an external thread. The rotation of the worm gear 502 is converted into the linear extension and retraction motion of the telescopic rod 504 through the threaded engagement: when the worm gear 502 rotates in the forward direction, the telescopic rod 504 extends upward; when the worm gear 502 rotates in the reverse direction, the telescopic rod 504 retracts downward; the material platform 505 rises and falls synchronously: the top of the telescopic rod 504 is directly fixed to the material platform 505, and when the extension and retraction of the telescopic rod 504 causes the overall height to change, the material platform 505 rises and falls synchronously with the telescopic rod 504;

[0041] Material transport and protection: The material platform 505 passes through the material chamber 6 (the material chamber 6 is fixedly connected to the personnel platform 202 and moves synchronously with the personnel platform 202). Materials are placed on the material platform 505 and vertical transport is achieved by lifting the material platform 505. The baffle 601 on the side of the material chamber 6 prevents materials from falling during transport and ensures safety. The personnel mechanism 2 and the material mechanism 4 are coordinated through the fixed connection between the material chamber 6 and the personnel platform 202: when the personnel platform 202 is lifted and lowered with the main lifting mechanism 3, the material chamber 6 is lifted and lowered synchronously (ensuring that the material transport height matches the personnel working height); the lifting of the material mechanism 4 is independent of the personnel mechanism 2 (the motors of both are independently controlled) and can operate synchronously or asynchronously as needed to meet the construction requirements of synchronously transporting materials to the working height when personnel reach that height.

[0042] This utility model has strong load-bearing capacity and adaptability, and is suitable for various construction scenarios. The personnel carrying mechanism uses a distributed load-bearing design with multiple sets of lifting frames and connecting rods, combined with the uniform force characteristics of screw drive. The material handling mechanism utilizes the speed reduction and torque increase characteristics of worm gear drive, which can effectively reduce the speed and increase the output torque. It is suitable for the transportation needs of heavy materials commonly found in electromechanical installation, and solves the problem that traditional light lifting equipment cannot carry heavy objects.

[0043] This utility model boasts high collaborative operation efficiency and meets the needs of synchronous construction. The equipment innovatively integrates two major modules: a personnel mechanism and a material mechanism. Collaborative linkage is achieved through the fixed connection between the material chamber and the personnel platform: when the personnel platform is raised and lowered, the material chamber moves synchronously to ensure that the material transportation height always matches the personnel working height. At the same time, the two are controlled by independent motors and can operate synchronously or asynchronously according to construction needs, which facilitates installation.

[0044] This utility model has a stable and reliable structure, ensuring operational safety. Regarding the personnel-carrying mechanism: the main lifting mechanism adopts a composite support structure, with multiple lifting frames connected by connecting rods to form a stable frame. The fixed block provides additional support for the connecting rods. With the precise sliding of the slider and the lead screw, the lifting process of the personnel-carrying platform is stable and without shaking. The baffle on the side of the material chamber prevents materials from falling during transportation. The threaded engagement between the telescopic rod and the worm gear ensures smooth transmission and guarantees a safe and controllable vertical transportation process for materials.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
