Description

Technical Field

[0001] This utility model belongs to the field of lifting equipment technology, specifically relating to an adjustable small lifting gantry. Background Technology

[0002] The lifting gantry is a new type of small lifting gantry developed to meet the daily production needs of small and medium-sized factories (companies) for handling equipment, warehouse loading and unloading, lifting and repairing heavy equipment, and transporting materials. It is suitable for mold manufacturing, auto repair shops, mines, civil construction sites, and other occasions requiring lifting. It is commonly used in construction for material transportation and for transporting construction workers up and down, realizing the mechanization of lifting. It can reduce manpower, lower production and operating costs, and improve work efficiency.

[0003] The existing gantry cranes are not convenient for height adjustment, making them unsuitable for lifting objects of different sizes, especially when the lifting site is uneven. Utility Model Content

[0006] The truss is equipped with a traveling crane that slides along its length.

[0007] Adjustment frames are symmetrically arranged on both sides of the lower end of the truss;

[0008] A support base, connected to the adjusting frame, provides upward support for the adjusting frame;

[0009] The adjusting frame includes an upper support rod connected to the truss, a lower support rod connected to the support base, and a telescopic component for driving the upper support rod and the lower support rod to slide relative to each other.

[0010] The upper support rod has several limiting through holes equidistantly arranged along its length. The relative position of the upper support rod and the lower support rod is limited by the cooperation of the fasteners with the limiting through holes.

[0011] Furthermore, the tail of the telescopic component is hinged to the lower support rod, and the head of the telescopic component is connected to the upper support rod via a locking component.

[0012] Furthermore, the engaging component has a U-shaped head that covers the outer periphery of the upper support rod.

[0013] Furthermore, the telescopic component is a cylinder.

[0014] Furthermore, the lower support rod is disposed on the outer periphery of the upper support rod.

[0015] Furthermore, the lower support rod has a rubber strip on its peripheral wall that contacts the upper support rod.

[0016] Furthermore, the lower support rod is also provided with several sets of limiting bolts that abut against the peripheral wall of the upper support rod.

[0017] Furthermore, the support base is triangular in shape.

[0018] Furthermore, the bottom of the support base is provided with rollers.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] The system employs a sliding adjustment frame. Fasteners and limiting holes allow the upper support rod to move vertically relative to the lower support rod before fixing it in place. When adjusting the height of one side of the gantry, the telescopic components allow the upper and lower support rods to slide smoothly relative to each other. This design is simple, easy to operate, and suitable for hoisting needs of different lengths. Attached Figure Description

[0030] like Figure 1 - Figure 5 As shown, an adjustable small lifting gantry of the present invention includes a truss 1, an adjusting frame, and a support base 3;

[0031] Among them, a traveling crane 2 is slidably configured along the length direction of truss 1;

[0032] The adjustment frames are symmetrically arranged on both sides of the lower end of truss 1;

[0033] Support base 3 is connected to the adjusting frame and provides upward support for the adjusting frame;

[0034] The adjusting frame includes an upper support rod 40 connected to the truss 1, a lower support rod 41 connected to the support base 3, and a telescopic member 6 for driving the upper support rod 40 and the lower support rod 41 to slide relative to each other.

[0035] The upper support rod 40 is provided with a number of limiting through holes 400 at equal intervals along its length. The relative position of the upper support rod 40 and the lower support rod 41 is limited by the cooperation of the fastener 7 with the limiting through holes 400.

[0036] An adjustable frame with relative sliding mechanism is used. The upper support rod 40 moves vertically relative to the lower support rod 41 and is then fixed in place via the engagement of fastener 7 and limiting through hole 400. When the height of one side of the gantry needs to be adjusted, the telescopic component 6 allows the upper support rod 40 and lower support rod 41 to slide smoothly relative to each other. This design is simple in structure, easy to operate, and suitable for hoisting needs of different lengths.

[0037] Specifically, the tail of the telescopic component 6 is hinged to the lower support rod 41, and the head of the telescopic component 6 is connected to the upper support rod 40 through the locking component 8.

[0038] To enable quick installation and disassembly of the telescopic component 6 during assembly with the upper support rod 40, a snap-fit ​​component 8 is designed, featuring a U-shaped head that covers the outer periphery of the upper support rod 40. For example... Figure 3 As shown, the U-shaped head is fixed to the upper support rod 40 with bolts.

[0039] The telescopic component 6 can be a motor, a screw mechanism, or other structures with telescopic functions, such as a cylinder. There are no specific restrictions, as long as it can drive the upper support rod 40 to move closer to or further away from the lower support rod 41. In this embodiment, the telescopic component 6 is a cylinder.

[0040] Specifically, the lower support rod 41 is disposed on the outer periphery of the upper support rod 40, and the lower support rod 41 has a rubber strip 410 on its peripheral wall that contacts the upper support rod 40.

[0041] This configuration can accommodate upper support rods 40 of different specifications and models. Several sets of limiting bolts 5 are also provided on the lower support rod 41 to abut against the circumference of the upper support rod 40. After the upper support rod 40 extends into the lower support rod 41, the limiting bolts 5 are tightened to make the ends of the limiting bolts 5 abut against the outer circumference of the upper support rod 40.

[0042] In addition, the support base 3 is triangular in shape. This design enhances the stability of the entire gantry frame.

[0043] The support base 3 is equipped with casters 30 at its bottom. The casters 30 are omnidirectional wheels, which can easily move the entire device and reduce handling costs.

[0044] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
