Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for electrical cabinet installation, specifically to a horizontal pushing mechanism for hoisting electrical cabinets, which is suitable for achieving precise horizontal movement and positioning of electrical cabinets in space-constrained environments such as power distribution rooms. Background Technology

[0002] During the installation of electrical cabinets in power distribution rooms, due to limited space and the typically heavy weight of the cabinets, traditional manual handling methods are not only inefficient but also pose safety hazards. Currently, although some hoisting equipment exists, these devices have shortcomings in horizontal movement control, making precise positioning difficult. For example, some existing horizontal pushing mechanisms use simple gear and rack transmissions or direct hydraulic cylinder propulsion. These methods have the following problems: low transmission efficiency, making rapid horizontal movement difficult; poor positioning accuracy, failing to meet the precise alignment requirements during electrical cabinet installation; complex structure, difficult maintenance, and large space occupation; and lack of an effective synchronization mechanism, leading to easy deviation during pushing, affecting hoisting safety. Therefore, there is an urgent need for a compact, efficient, and precisely positioned horizontal pushing mechanism to solve the problems existing in current technologies. Utility Model Content

[0003] The purpose of this invention is to provide a horizontal pushing mechanism for hoisting electrical cabinets, which enables rapid and precise horizontal movement and positioning of the electrical cabinets through a speed-increasing transmission structure and a synchronization mechanism.

The lowering mechanism moves axially; one end of the positioning rod is fixed to the L-shaped support, and the other end extends into the inside of the boom (the width of the positioning rod is smaller than the width inside the boom so that the positioning rod can move left and right without affecting the wire rope), and two threaded positioning blocks are installed at the end of the positioning rod that extends into the boom; the boom is movably provided with a movable lifting lug, and the left and right ends of the boom are respectively connected to a reversing wheel, and two wire ropes are respectively connected to a positioning block, and each wire rope is arranged in the opposite direction along the positioning rod (3.9), and after being guided by the reversing wheel, it is fixed to both ends of the movable lifting lug, so that the moving distance of the movable lifting lug relative to the moving trolley is twice the moving distance of the lifting mechanism relative to the moving trolley.

[0005] Preferably, the connection between the column I and the mobile trolley is by welding or bolting to ensure the verticality and stability of the column I.

[0006] Preferably, a guide structure is provided between the sleeve I and the column I. The guide structure is a combination of a slider and a groove to ensure that the sleeve I slides smoothly along the column I.

[0007] Preferably, the drive sprocket and the driven sprocket are made of alloy steel to improve the wear resistance and strength of the sprocket.

[0008] Preferably, the thread of the helical push rod is a trapezoidal thread with a pitch of 5-10 mm and a thread angle of 30° to provide sufficient transmission efficiency and load-bearing capacity.

[0009] Preferably, the positioning block and the positioning rod are connected by a thread and equipped with a lock nut to prevent the positioning block from loosening.

[0015] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] In the description of the utility model, it should be noted that the terms "upper", "lower", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The technical solution / principle of this application: The horizontal pushing mechanism includes a support structure, a transmission structure, and a synchronization structure;

[0019] The supporting structure includes a column I 3.1, a sleeve I 3.2, and an L-shaped support 3.3. The column I 3.1 is vertically fixed on the moving trolley, the sleeve I 3.2 can slide along the column I 3.1, and the L-shaped support 3.3 is connected to the top of the sleeve I 3.2 to provide support for subsequent components.

[0020] The transmission structure includes a drive sprocket 3.4, a handwheel 3.5, a chain 3.6, a driven sprocket 3.7, and a screw push rod 3.8. The handwheel 3.5 drives the drive sprocket 3.4 to rotate, which in turn drives the driven sprocket 3.7 via the chain 3.6. The driven sprocket 3.7 then drives the screw push rod 3.8 to rotate, thereby pushing the lifting mechanism to move axially (because one end of the positioning rod 3.9 extends into the boom 2.7, it serves as a guide and can only push the lifting mechanism to move left and right under the action of the screw push rod 3.8; its structural principle is similar to the one-piece slide structure of a ball screw).

[0021] The synchronous structure includes a positioning rod 3.9, a positioning block 3.10, a wire rope, and a reversing wheel 2.9. Through the linkage of the positioning rod 3.9 and the wire rope, the moving distance of the movable lifting lug 2.8 is twice that of the lifting mechanism, thereby improving operational flexibility and positioning accuracy.

[0022] Example 1: Referring to the accompanying drawings Figure 1-4 The specific embodiments of this utility model are described below:

[0023] Structural Assembly: Vertically fix column I 3.1 to the end face of the moving trolley near the handle, ensuring the verticality error of column I 3.1 does not exceed 0.5 mm / m; Sleeve I 3.2 is fitted onto the outside of column I 3.1, and a guide slider is installed between them to allow sleeve I 3.2 to slide smoothly along column I 3.1; Weld an L-shaped support 3.3 to the top of sleeve I 3.2, and install a drive sprocket 3.4 and a handwheel 3.5 on the L-shaped support 3.3; Install a driven sprocket 3.7 on the other side of the L-shaped support 3.3, and connect the drive sprocket 3.4 and the driven sprocket 3.7 via a chain 3.6. Ensure that the number of teeth on the drive sprocket 3.4 is greater than the number of teeth on the driven sprocket 3.7 to form a speed-increasing transmission structure; fix the helical push rod 3.8 coaxially with the driven sprocket 3.7 and make the helical push rod 3.8 threadedly engaged with the helical sleeve 2.6 of the lifting mechanism; fix the positioning rod 3.9 on the L-shaped support 3.3 and extend the other end of the positioning rod 3.9 into the boom 2.7, and install two threaded positioning blocks 3.10 at the end of the positioning rod 3.9; connect a steel wire rope to each positioning block 3.10, and after the two steel wire ropes are guided by two reversing wheels 2.9, fix them to both ends of the movable lifting lug 2.8.

[0024] Working principle / method:

[0025] When the electrical cabinet needs to be moved horizontally (the cabinet is held in place by hooks on the lifting mechanism), the operator turns handwheel 3.5, driving drive sprocket 3.4 to rotate. Drive sprocket 3.4 drives driven sprocket 3.7 to rotate via chain 3.6. Since drive sprocket 3.4 has more teeth than driven sprocket 3.7, driven sprocket 3.7 rotates at a faster speed. Driven sprocket 3.7 drives spiral push rod 3.8 to rotate. The spiral push rod 3.8 engages with the spiral sleeve 2.6, converting rotational motion into linear motion, thereby driving the lifting mechanism to move axially. As the lifting mechanism moves, positioning rod 3.9 moves accordingly. Through the linkage of positioning block 3.10 and wire rope, the moving lug 2.8 moves twice the distance of the moving trolley relative to the lifting mechanism, achieving fast and accurate horizontal positioning.

[0026] Advantages of the technical solution in this application:

[0027] Speed-increasing transmission: Speed-increasing transmission is achieved by the difference in the number of teeth between the driving sprocket 3.4 and the driven sprocket 3.7, thereby improving the efficiency of horizontal propulsion;

[0028] Synchronization mechanism: Through the linkage of positioning rod 3.9 and wire rope, the moving distance of movable lifting lug 2.8 is doubled, enhancing operational flexibility;

[0029] Compact structure: The overall structure is reasonably designed and occupies little space, making it suitable for use in confined spaces such as power distribution rooms; Precise positioning: The threaded fit between the 3.8 spiral push rod and the 2.6 spiral sleeve provides precise linear movement control.

[0030] Finally, it should be noted that this utility model is not limited to the above embodiments, and many variations are possible. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
