Description

Scissor lift

Technical Field

The utility model relates to the technical field of elevators, especially, relate to a cut fork lift.

Background

In the prior art, the electric cylinder, the hydraulic cylinder or the electric hydraulic cylinder on the scissor lift has a cylinder body fixedly connected with the base, an output end fixedly connected with the inclined strut, and the inclined strut is driven by the driving cylinder to be supported or laid flat, so that the lifting platform is lifted or lowered. When the scissor lift is used, the maximum height and the bearing capacity of the scissor lift are considered, a large driving cylinder is generally adopted to drive, the large driving cylinder is large in size and high in energy consumption, and the minimum height is higher when the scissor lift is contracted, so that the scissor lift is inconvenient to store.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that: in order to overcome and cut fork lift driving cylinder among the prior art bulky, the power consumption is high, leads to the inconvenient not enough of accomodating of lift, the utility model provides a cut fork lift.

In addition, in the lifting process of the lifter, the driving cylinder is always kept in a vertical state, compared with the inclined arrangement of the driving cylinder on the lifter in the prior art, the lifting is more stable, and because the driving cylinder is always in the vertical state, the output shaft cannot be inclined, and the service life of the driving cylinder is longer.

Further, in order to enable the elevator to be lower in minimum height during contraction, a first accommodating cavity is formed in the base, a second accommodating cavity is formed below the lifting platform, the lower end of the first inclined strut is hinged to the side wall of the first accommodating cavity, the upper end of the first inclined strut is abutted to the top wall of the second accommodating cavity, the upper end of the second inclined strut is hinged to the side wall of the second accommodating cavity, and the lower end of the second inclined strut is connected with the side wall of the first accommodating cavity in a sliding mode in the horizontal direction. When the elevator contracts, partial structures of the first inclined support, the second inclined support and the driving cylinder are located in the first accommodating cavity and the second accommodating cavity, the space utilization rate is high, and the lowest height of the elevator during contraction becomes low.

Furthermore, in order to reduce the friction force in the lifting process and make the lifting process smoother, a connecting shaft is arranged at the lower end of the second inclined strut in a penetrating mode, rollers are arranged at two ends of the connecting shaft, and a sliding groove matched with the rollers is formed in the side wall of the first accommodating cavity.

Further, in order to improve the space utilization rate of the elevator and enable the minimum height of the elevator to be lower when the elevator contracts, the second supporting plate is arranged below the first supporting plate, extending plates are arranged on two sides of the second supporting plate, and the extending plates and the second inclined supports penetrate through rotating shafts to enable the extending plates to be rotatably connected with the second inclined supports. By extending the plates, the second support plate is brought into close proximity to the ground when the lift is retracted, thereby leaving sufficient space for the drive cylinder.

Further, the driving cylinder is an electric cylinder, a hydraulic cylinder or an electric hydraulic cylinder.

Further, in order to prevent that the driving cylinder from becoming invalid and leading to the lifting platform to fall suddenly, still include the locking subassembly, the locking subassembly includes two gag lever posts that set up relatively, two the gag lever post upper end is rotated with the second both sides wall that holds the chamber respectively and is connected, two be connected with the connecting rod between the gag lever post lower extreme, the connecting rod supports to be located on the second bracing inclined plane, the position on the upper side in the middle of the second bracing inclined plane be equipped with connecting rod complex stopper. Through with the connecting rod card on the stopper for gag lever post, lift platform and second bracing form stable triangle-shaped, prevent that the actuating cylinder inefficacy from leading to lift platform to fall suddenly.

Furthermore, when the elevator is lifted conveniently, the connecting rod can be automatically clamped into the limiting block, the lower end of the limiting block is a guide part which is obliquely arranged, and the upper end of the limiting block is matched with the inclined surface of the second inclined strut to form a limiting part which is used for limiting the position of the connecting rod.

The utility model has the advantages that: the utility model provides a pair of scissor lift adopts on the first bracing of mutual articulated and the second bracing that all set up the both ends of driving cylinder for the driving cylinder stroke is required to be diminished, and the volume is littleer, and the power consumption is lower, and then minimum height step-down when the lift contracts, convenient storage.
