Description

Sliding trolley mechanism

Technical Field

The invention relates to the field of industrial machinery, in particular to a sliding trolley mechanism.

Background

For heavy traditional work bench, the need of lifting or directly dragging an object moving fast is overcome, if wheels are used to roll, the friction coefficient between the wheels and the contact surface can be greatly reduced, but a great amount of force is required to be consumed, if the work bench is in a rack structure, the work bench surface can be destroyed when facing the heavy structure, so that a work bench trolley capable of sliding is needed to be studied urgently.

Disclosure of Invention

In order to solve the technical problems, the sliding trolley mechanism comprises a sliding trolley body, pulleys are arranged at the top of the sliding trolley body and distributed in groups, the number of the pulleys is three, the three pulleys are symmetrically distributed, a lifting ring bearing plate is arranged at the bottom of the sliding trolley body, lifting ring nuts are arranged at the bottom of the lifting ring bearing plate, the lifting ring bearing plate is connected with the sliding trolley body in a matched manner through rubber pads, flat washers and hexagonal nuts, the pulleys are arranged on the trolley shaft through welding nuts, deep groove ball bearings are arranged on the trolley shaft, and check rings are arranged outside the deep groove ball bearings.

As an improvement, the pulley blocks are symmetrically distributed on two sides of the sliding trolley body, the two pulleys are connected through the trolley shafts, and the balance of the trolley can be well guaranteed through the distributed structures on the two sides, so that the purpose of lifting the object is achieved.

As an improvement, the trolley axle is arranged at the center of the pulley, and the smoothness of the movement of the trolley can be ensured to the greatest extent by being arranged at the center of the pulley.

As an improvement, the symmetrical axis of the pulley is the central axis of the sliding trolley body, and the symmetrically distributed pulleys can ensure that the gravity center of the trolley is stable, and the pulley cannot be inclined or toppled over due to gravity center deviation in the running process.

As an improvement, the lifting ring bearing plate is connected with the sliding trolley body in a matched manner through a hexagonal bolt, a hexagonal nut II, a flat washer II and a spring washer, and the bolts are symmetrically distributed on two sides for fixing.

Compared with the prior art, the technical scheme of the invention has the following advantages: according to the sliding trolley mechanism, no obvious gap exists between the wheel shafts after the assembly is completed, and each pulley flexibly rotates, so that the clamping stagnation phenomenon is avoided; a locking mark is made at the threaded connection part; the whole trolley is used for carrying test, and all parts are not damaged under the action of 14KN static load.
