Description

Technical Field

[0001] This utility model relates to the field of electromechanical construction equipment technology, specifically to a lifting device for electromechanical installation and construction. Background Technology

[0002] In electromechanical installation projects, it is often necessary to lift equipment such as motors, fan coil units, or long components such as air ducts and cable trays to high places for installation. Currently, the commonly used equipment mainly includes scissor lifts, aluminum alloy lifting platforms, or simple gantry cranes.

[0003] The existing lifting devices have the following technical problems in electromechanical construction: To prevent tipping during high-altitude operations, the base of the lifting device typically needs to be quite wide (span). However, construction site environments are complex, with narrow corridors and doorways, making it impossible for equipment with a wide base to pass through. While equipment with a narrow base is more flexible to move, it has poor stability when lifting heavy objects, posing significant safety hazards. Traditional hoisting baskets can only lift and lower the equipment vertically, and a pendulum effect can easily occur during the lifting process, making it impossible to stably rotate and adjust the equipment's installation position. Once the equipment is in place, if there is a deviation in the installation position, workers need to painstakingly adjust the equipment's angle, which is not only inefficient but also prone to accidents when moving it at height. Utility Model Content

[0004] To overcome the problems in the prior art, this utility model provides a lifting device for electromechanical installation and construction. It achieves the adjustment of the base support span through a sliding gantry structure, thus resolving the contradiction between mobility and operational stability. Furthermore, it improves installation accuracy and safety by cooperating with a rotation and guiding mechanism.

[0005] A lifting device for electromechanical installation includes a movable base, a gantry frame, a balance frame, a sliding rail, a lifting mechanism, a hoisting basket, and a limiting component. The movable base has wheels at its bottom. The gantry frame straddles the movable base on one side facing it. The balance frame is connected to the rear of the gantry frame via a crossbeam. The sliding rail is installed on the movable base below the gantry frame and the balance frame. The legs of the gantry frame and the balance frame are connected to sliders on the sliding rail. One end of the slider extends from the sliding rail towards the gantry frame, and a support wheel is installed at its end. The support wheel and the wheels are on the same horizontal plane. The lifting mechanism is installed on the crossbeam at the top of the gantry frame. The power output end of the lifting mechanism is connected to the hoisting basket. Guide rods are provided on both sides of the hoisting basket. The guide rods slide in engagement with longitudinal guide grooves installed on the columns of the gantry frame. The limiting component is rotatably mounted on the movable base.

[0006] Furthermore, a rotating tray is installed inside the hoisting basket, and the rotating tray is rotatably installed via a pivot embedded in the bottom plate of the hoisting basket.

[0007] Furthermore, the limiting component is a rotating support leg, which is hinged to the end face of the movable base via a pin. The rotating support leg rotates around the pin to switch between the vertical limiting support state and the storage state.

[0008] Furthermore, a handrail frame one is provided on one side of the movable base, and a handrail frame two is connected between the gantry frame and the balance frame.

[0009] Furthermore, a limit plate is provided on the support wheel, and a flexible limit block corresponding to the limit hole of the limit plate is provided on the bottom wall of the movable base.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes the cooperation of sliding rails and sliders to allow the gantry frame to move laterally relative to the mobile base. During relocation, the gantry frame retracts, resulting in a narrow overall width and good maneuverability. During lifting operations, the gantry frame slides out, driving the support wheels to extend outward, which not only widens the support area of ​​the chassis and improves anti-overturning ability but also allows the equipment to be docked with the work station in the horizontal direction. At the same time, by utilizing the guide rods on both sides of the lifting basket in cooperation with the longitudinal guide grooves on the gantry frame, the soft lifting is transformed into rigid guided lifting, preventing the basket from swaying during the ascent.

[0011] 2. The rotating pallet inside the hoisting basket of this utility model allows workers to easily rotate the hoisted object at high altitudes to quickly align it with the installation position, reducing labor intensity. The limiting component can lift or lock the wheels off the ground, and together with the extended support wheels, a stable multi-point support structure is formed to ensure construction safety.

Detailed Implementation

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0016] like Figures 1 to 6 As shown, a lifting device for electromechanical installation and construction is composed of a steel structure frame and a drive assembly, including a rectangular frame type mobile base 1, with universal or directional wheels 11 installed at the four corners of the bottom of the mobile base 1 for pushing and moving the device. The gantry frame 2 and the balance frame 3 form the main frame of the upper part of the mobile base 1. The gantry frame 2 is located at the front and mainly bears the hoisting force. The balance frame 3 is located at the rear and is connected to the gantry frame 2 through a crossbeam, which plays the role of structural reinforcement and counterweight balance. In order to facilitate manual pushing, a handrail frame 8 is welded on one side of the mobile base 1, and a handrail frame 9 is connected between the gantry frame 2 and the balance frame 3, so that workers can operate from different positions. like Figure 1 and Figure 4 As shown in the comparison, the sliding rail 4 is horizontally fixed on the movable base 1, the gantry 2 and the balance frame 3 are fixed on the slider 41 by the support feet, the slider 41 is slidably engaged in the sliding rail 4, the front end of the slider 41 extends outward and is equipped with a support wheel 42. like Figure 1 As shown, in the storage and moving state, the slider 41 is retracted into the track, the support wheel 42 is close to the moving base 1, the width of the whole machine is minimized, which makes it easy to enter and exit elevators or narrow doorways. The support wheel 42 is fixed by engaging with the flexible limit block 12 through the limit plate 421, such as a rubber block or spring pin structure. like Figure 4 As shown, in the working state, the gantry 2 and the balance frame 3 slide outward along the sliding track 4 as a whole, and the slider 41 drives the support wheel 42 to move outward. At this time, the support wheel 42 and the original wheel 11 of the base support the ground together, which significantly increases the lateral support span of the entire device (30%-50%), which not only ensures the lateral stability when hoisting heavy objects, but also enables the hoisting equipment to be moved horizontally in the air, making it convenient to connect with the construction position. The mobile base 1 is also equipped with a limiting component 7, which is designed as a rotating support foot. The support foot is hinged to the end face of the base by a pin. When operation is required, it is rotated to a vertical downward position to support the ground, so that the wheels 11 are slightly off the ground or increase friction to prevent the equipment from sliding. When it needs to be moved, it is rotated upward to store it.

[0017] like Figure 2 As shown, in this embodiment, the lifting mechanism 5 uses an electric hoist, which is installed on the crossbeam at the top of the gantry frame 2. Its hook is connected to the hoisting basket 6. The inner side of the columns on both sides of the gantry frame 2 is equipped with longitudinal guide grooves 21, such as C-shaped steel grooves. T-shaped or roller-type guide rods 61 are welded on both sides of the hoisting basket 6. When the hoisting basket 6 is lifted, the guide rods 61 slide in the longitudinal guide grooves 21, which restricts the free swing of the basket. like Figure 6 As shown, a circular rotating support plate 62 is provided on the bottom plate inside the hoisting basket 6. The center of the rotating support plate 62 is connected to the bottom plate of the hoisting basket through a rotating shaft 63. During construction, workers place the electromechanical equipment on the rotating support plate 62. After it is raised to a high altitude, they only need to gently rotate the support plate to adjust the horizontal angle of the equipment, so that its flange holes or mounting holes are accurately aligned, which is stable and efficient.

[0018] Work process: Move and position: Keep gantry 2 in the retracted state ( Figure 1 ), and push the handrail to move the device directly below the construction point; Deployment and Fixation: One operator lowers the limiting component 7 to fix the base, unlocks the flexible limiting block 12, and stabilizes the base 1; another operator manually or with auxiliary mechanisms pulls the gantry 2 and the balance frame 3 outwards until the support wheel 42 extends to the workstation. Figure 4 ); Lifting operation: Place the equipment to be installed onto the rotating pallet 62 of the lifting basket 6, start the lifting mechanism 5, and the lifting basket 6 will rise smoothly along the longitudinal guide groove 21; Alignment installation: After reaching the designated height, the worker rotates the rotating pallet 62 to fine-tune the equipment angle for installation; Reset: After installation, lower the hoisting basket, retract the gantry 2 to the initial position, retract the limit component 7, and move to the next construction point.

[0019] 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.
