Description

Technical Field

[0001] This utility model relates to the field of material hoisting technology, specifically to a movable chassis for a small material hoist. Background Technology

[0002] A small material hoist is a small mechanical device that can lift materials. It includes a lifting frame and a movable chassis. In the prior art, the movable chassis of the lifting frame has two stable support legs, and the support legs and the bottom of the chassis are equipped with casters. This chassis structure has poor stability when lifting materials. When the center of gravity of the material shifts, it is easy to tip over, which can easily cause injury to personnel. To address the above problems, a movable chassis for a small material hoist is needed. Utility Model Content

[0026] Figures 1-4 The diagram shown is a structural schematic of the first embodiment of the movable chassis of a small material hoist according to this utility model. Please refer to [link / reference]. Figures 1-4 The movable chassis of a small material hoist according to this embodiment includes a movable chassis 100 as its main body.

[0027] The mobile chassis 100 is provided with a fixed support leg 110 at the front and an adjustable support leg 130 rotatably connected to the rear of the mobile chassis 100. An adjusting gear 131 is provided on the adjustable support leg 130 and is connected to the adjusting assembly 200. The adjusting assembly 200 includes a turntable 210, which is connected to a worm gear 220 via a shaft. Driven gears 230 are meshed on both sides of the worm gear 220 and are meshed with the adjusting gear 131.

[0028] The mobile chassis 100 has a bearing groove 150 at the rear. The adjustment component 200 is located in the inner cavity of the bearing groove 150, and an inspection cover 240 is installed on the top of the bearing groove 150. A lifting frame 120 is installed on the top of the mobile chassis 100. Universal wheels 140 are installed at the bottom of the mobile chassis 100, the fixed support legs 110, and the adjustable support legs 130. The adjustable support legs 130 are located on both sides of the bearing groove 150 and are connected to the mobile chassis 100 through shafts. The turntable 210 is located on the outside of the mobile chassis 100 and is connected to the worm gear 220 located in the bearing groove 150 through a shaft. There are two driven gears 230 and they are connected to the mobile chassis 100 through a rotating shaft.

[0029] The mobile chassis 100 is used to support the lifting frame 120, fixed support legs 110 and adjustable support legs 130. The lifting frame 120 is used to lift materials. The fixed support legs 110 and adjustable support legs 130 are used to increase the stability of the mobile chassis 100. The adjustable support legs 130 can be stored and unfolded to improve practicality. The adjusting gear 131 is used to connect with the adjusting component 200 to facilitate changing the position of the adjustable support legs 130. The casters 140 are used to realize the movement function of the mobile chassis 100. The bearing groove 150 is used to support the adjusting component 200.

[0030] The adjustment assembly 200 is used to facilitate changing the position of the adjustment leg 130. The turntable 210 is fixedly connected to the worm gear 220 via a shaft. When the turntable 210 rotates, it can drive the worm gear 220. The worm gear 220 drives the driven gear 230 to rotate. When the driven gear 230 rotates, it drives the adjustment gear 131 to rotate. When the adjustment gear 131 rotates, it realizes the rotation of the adjustment leg 130. The inspection cover 240 is used to close the bearing groove 150 to prevent foreign objects from entering the bearing groove 150 and affecting the adjustment assembly 200, and also facilitates the maintenance of the adjustment assembly 200.

[0031] The adjustable support leg 130 can be rotated by adjusting component 200, which increases the stability of the movable chassis 100. When rotating turntable 210, worm gear 220 will rotate, which drives the driven gears 230 meshing on both sides to rotate. When the two driven gears 230 rotate, they drive the adjustable support leg 130 to rotate. When the adjustable support leg 130 is turned to the rear of the movable chassis 100, the stability of the movable base can be increased. When not in use, the adjustable support leg 130 can be turned to the side of the fixed support leg 110 to reduce the space required for storage.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
