Description

Technical Field

[0001] This utility model relates to the field of mobile transportation equipment, specifically to a mobile trolley with a fine-tuning mechanism. Background Technology

[0002] In the construction industry, mobile trolleys are important transportation and auxiliary equipment, often used for the handling and installation of various modular components. However, most existing mobile trolleys only have the function of moving as a whole along a fixed track. After the trolley stops, it is difficult to achieve high-precision position calibration and fine-tuning of the modular components they carry, affecting the accuracy of modular installation and construction efficiency.

[0003] Due to factors such as component prefabrication errors, limitations in the precision of hoisting equipment, and complex on-site installation environments, modular components often exhibit deviations of a few millimeters during installation. These seemingly minor deviations can lead to difficulties in precisely assembling modules, causing problems such as wall misalignment, poor pipeline connections, and inadequate sealing of doors and windows, severely impacting the building's structural stability, waterproofing and insulation performance, and overall aesthetics.

[0004] Currently, construction workers typically need to use traditional methods such as wedge adjustment and shim addition / reduction for on-site calibration. These methods are not only cumbersome and time-consuming, but also highly dependent on the experience of the construction workers, making it difficult to guarantee adjustment accuracy, easily leading to repeated rework, and significantly increasing construction costs and the risk of project delays.

[0005] Therefore, there is an urgent need to develop an auxiliary installation device that can achieve high-precision fine-tuning along the X and Y axes, has a stable structure, and is easy to operate, so as to effectively solve the precision problem in the modular building installation process. Utility Model Content

This invention provides a mobile trolley with a fine-tuning mechanism. By setting a fine-tuning mechanism between the frame and the main equipment, the main equipment can be precisely adjusted in the XY axis, thereby improving the positioning accuracy and operating efficiency of the mobile trolley.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following solution: The present invention provides a mobile trolley with a fine-tuning mechanism, comprising a frame body, a power unit for driving the frame body to move along a track, and a main equipment. The mobile trolley also includes a fine-tuning mechanism, which is disposed between the frame body and the main equipment.

[0008] The main body is supported by the fine-tuning mechanism and driven by the fine-tuning mechanism to make fine-tuning movements along the XY axes.

[0009] Furthermore, the fine-tuning mechanism is an XY axis drive mechanism.

[0010] Furthermore, the XY axis drive mechanism includes a Y-axis drive mechanism located at the lower part and an X-axis drive mechanism located at the upper part, wherein the Y-axis drive mechanism drives the X-axis drive mechanism to move along the Y-axis.

[0011] Furthermore, the upper end of the vehicle frame body is provided with Y-axis double guide rails and a first hinge column along the Y-axis;

[0013] A Y-axis power source, the first end of which is hinged to the first hinge post;

[0014] The Y-axis support has multiple Y-axis rollers at its lower end that move along the Y-axis double guide rails. The upper end of the Y-axis support is provided with X-axis double guide rails. The second end of the Y-axis power source is hinged to the Y-axis support and the Y-axis power source drives the Y-axis support to move.

[0015] The X-axis drive mechanism includes:

[0016] The X-axis support has multiple X-axis rollers at its lower end that move along the X-axis double guide rails. The main body equipment is mounted on the upper end of the X-axis support, and a second hinge column is connected to its side.

[0017] An X-axis power source has a first end hinged to the second hinge post, and a second end hinged to the X-axis support, which is driven by the X-axis power source to move in the X-axis direction.

[0021] Furthermore, the X-axis roller is a roller with dual bearings.

[0022] Furthermore, the power unit is a geared motor that drives the support wheels connected to the main body of the frame.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The mobile trolley of this utility model can make precise fine adjustments and improve installation accuracy: by setting an XY axis drive mechanism between the main frame and the main equipment, the main equipment can be finely adjusted in the X and Y axes, which effectively solves the problem of misalignment of a few millimeters caused by prefabrication errors and hoisting deviations when installing modular components.

[0025] 2. The mobile trolley of this utility model simplifies operation and improves construction efficiency: The mobile trolley of this utility model uses a fine-tuning mechanism driven by a hydraulic cylinder, which only needs to control the power source to complete precise adjustments, greatly shortening calibration time, reducing rework, reducing the labor intensity of construction workers, significantly improving the construction efficiency of modular building installation, and shortening the construction period.

[0026] 3. The mobile trolley structure of this utility model is stable, ensuring reliable operation: the Y-axis support moves along the Y-axis double guide rail via a Y-axis roller with double bearings, and the X-axis support moves along the X-axis double guide rail via an X-axis roller with double bearings. The cooperation between the double guide rails and the double bearing rollers not only improves the stability of the support but also reduces frictional resistance and wear during movement, ensuring a smooth and stable fine-tuning process. At the same time, the power source is connected by a hinge, which can adapt to small angle changes during the fine-tuning process, further making the fine-tuning mechanism more reliable and extending the service life of the equipment.

[0032] Example 1: The specific structure of this utility model is as follows:

[0033] Please refer to the appendix. Figure 1-2 This utility model discloses a mobile trolley with a fine-tuning mechanism, comprising a frame body 1, a power unit 16 for driving the frame body 1 to move along a track, and a main device 3. The power unit 16 is a geared motor, which drives support wheels connected to the frame body 1. The support wheels are provided with driving wheels 10 and driven wheels 7, and the driving wheels 10 are driven by the geared motor.

[0034] The mobile vehicle also includes a fine-tuning mechanism, which is located between the vehicle frame body 1 and the main equipment 3;

[0035] The main body device 3 is supported by the fine-tuning mechanism and is driven by the fine-tuning mechanism to make fine-tuning movements in the XY axes.

[0036] The fine-tuning mechanism is an XY axis drive mechanism.

[0037] The XY axis drive mechanism includes a Y-axis drive mechanism located at the bottom and an X-axis drive mechanism located at the top. The Y-axis drive mechanism drives the X-axis drive mechanism to move along the Y-axis.

[0038] The upper part of the frame body 1 is provided with Y-axis double guide rail 13 and first hinge column 17 along the Y-axis.

[0039] The Y-axis drive mechanism includes:

[0040] Y-axis power source 14, the first end of which is hinged to the first hinge post 17;

[0041] Y-axis support 2, the lower end of which moves along Y-axis double guide rail 13 via multiple Y-axis rollers 11, the upper end of which is provided with X-axis double guide rail 15, the second end of the Y-axis power source 14 is hinged to the Y-axis support 2 and the Y-axis power source 14 drives the Y-axis support 2 to move;

[0042] The X-axis drive mechanism includes:

[0043] The X-axis support 4 has multiple X-axis rollers 12 at its lower end that move along the X-axis double guide rail 15. The main body device 3 is installed at the upper end of the X-axis support 4, and a second hinge column 6 is connected to its side.

[0044] X-axis power source 5, the first end of which is hinged to the second hinge post 6, and the second end of which is hinged to the X-axis support 4, and the X-axis support 4 is driven by the X-axis power source 5 to move in the X-axis direction.

[0045] The Y-axis power source 14 is a first hydraulic cylinder. The fixed end of the first hydraulic cylinder is connected to the first hinge column 17, and its movable end is connected to the Y-axis support 2.

[0046] The X-axis power source 5 is a second hydraulic cylinder. The fixed end of the second hydraulic cylinder is connected to the second hinge column 6, and its movable end is connected to the X-axis support 4.

[0047] Both the Y-axis roller 11 and the X-axis roller 12 are rollers with double bearings, and the rollers with bearings have low friction during movement.

[0048] Example 2:

[0049] The following is the implementation process of the fine-tuning function of the mobile trolley in this utility model. The specific operation process is as follows:

[0050] Y-axis fine adjustment: Start the Y-axis power source 14 (hydraulic cylinder) to control the piston rod of the hydraulic cylinder to extend or retract. Since one end of the hydraulic cylinder is hinged to the first hinge post 17 of the frame body 1 and the other end is hinged to the Y-axis support 2, the extension and retraction of the piston rod (i.e., the movable end of the first hydraulic cylinder mentioned above) will push the Y-axis support 2 to make linear motion along the Y-axis double guide rail 13.

[0051] The X-axis drive mechanism is mounted on the upper end of the Y-axis support 2, and the main body 3 is mounted on the X-axis support 4 of the X-axis drive mechanism. Therefore, the movement of the Y-axis support 2 will drive the X-axis drive mechanism and the main body 3 to move synchronously along the Y-axis, realizing the fine adjustment of the main body 3 along the Y-axis. During the fine adjustment process, the Y-axis roller 11 rolls along the Y-axis double guide rail 13. The double bearing structure ensures that the Y-axis support 2 moves smoothly, avoiding jamming or offset, and ensuring the accuracy of the Y-axis fine adjustment.

[0052] X-axis fine adjustment: Start the X-axis power source 5 (hydraulic cylinder) to control the piston rod of the hydraulic cylinder to extend or retract. Since one end of the hydraulic cylinder is hinged to the second hinge post 6 of the X-axis support 4 and the other end is hinged to the other side of the X-axis support 4, the extension and retraction of the piston rod (i.e., the movable end of the second hydraulic cylinder mentioned above) will directly push the X-axis support 4 to make linear motion along the X-axis double guide rail 15.

[0053] The main device 3 is mounted on the upper end of the X-axis support 4. Therefore, the movement of the X-axis support 4 will drive the main device 3 to move synchronously along the X-axis, realizing the fine adjustment of the main device 3 in the X-axis direction. Similarly, the double bearing structure of the X-axis roller 12 ensures the smooth movement of the X-axis support 4 and guarantees the accuracy of the fine adjustment in the X-axis direction.

[0054] By controlling the movements of the Y-axis power source 14 and the X-axis power source 5 respectively, the main equipment 3 can be fine-tuned at any position in the XY plane, meeting the positional accuracy requirements of the main equipment 3 in different scenarios. After the fine-tuning is completed, the Y-axis power source 14 and the X-axis power source 5 are turned off. The piston rod of the hydraulic cylinder remains in its current position. Utilizing the self-locking characteristic of the hydraulic cylinder (or in conjunction with a locking mechanism), the main equipment 3 is ensured to remain stably in the fine-tuned position, preventing positional deviation caused by external forces.

[0055] In summary, the mobile trolley of this utility model can make precise fine adjustments and improve installation accuracy: by setting an XY axis drive mechanism between the main frame and the main equipment, high-precision fine adjustments of the main equipment in the X and Y axes can be achieved, effectively solving the problem of misalignment of a few millimeters caused by prefabrication errors and hoisting deviations during the installation of modular components.

[0056] The mobile trolley of this invention simplifies operation and improves construction efficiency: The mobile trolley of this invention uses a fine-tuning mechanism driven by a hydraulic cylinder, which only requires control of the power source to complete precise adjustments, greatly shortening calibration time, reducing rework, reducing the labor intensity of construction workers, significantly improving the construction efficiency of modular building installation, and shortening the construction period.

[0057] The mobile trolley structure of this utility model is stable, ensuring reliable operation: the Y-axis support moves along the Y-axis double guide rail via a Y-axis roller with double bearings, and the X-axis support moves along the X-axis double guide rail via an X-axis roller with double bearings. The cooperation between the double guide rails and the double bearing rollers not only improves the stability of the support but also reduces frictional resistance and wear during movement, ensuring a smooth and stable fine-tuning process. At the same time, the power source is connected by a hinge, which can adapt to small angle changes during the fine-tuning process, further making the fine-tuning mechanism more reliable and extending the service life of the equipment.
