Problems solved by technology

The hydraulic cylinders of the prior art hydraulic elevators are installed on the ground, and when the plunger rod in the hydraulic cylinder moves from bottom to top, the car and goods are transported from the bottom layer to the high floor. Active force, one is the gravity of the car, and the other is the gravity of the plunger rod. Because the hydraulic cylinder is large, the weight of the plunger rod reaches several hundred kg to thousands of kg. Disadvantages are high power consumption and high operating costs

Embodiment

[0010] Embodiment: ①. Use the plunger rod of the inverted 2:1 oil cylinder plus the weight of the pulley group to bear the force of the car, such as: the stroke is 12m, the weight of the ?110×6500mm plunger rod is 500kg + the weight of the lower pulley group is 150kg, The weight of the car is 1000kg. When the plunger rod and the pulley block move downward, the 325kg weight of the upward movement of the car can be offset, that is, the hydraulic cylinder only needs to exert a force of 675kg to make the car move upward.

[0011] Suppose the travel of the car is 12m, the total weight of the car and the goods carried is 2.5t, and the lifting times of the car are 50 times per day.

[0012] When using an electric hoist, 12m×2.5t=300KN, 300KN×100 times=30000KN, 30000KN÷3600s=8.333 kWh;

[0013] When a hydraulic elevator with a hydraulic cylinder installed on the ground is used, the car goes down without being driven by a motor, 0.65t (weight of the plunger rod + weight of the lower pu...

Abstract

A hang-upside-down type hydraulic goods lift is characterized in that an inversed type hydraulic cylinder is arranged under a steel beam, a lower pulley is arranged in a lower pulley support arranged under a flange on the head portion of a plunger post to be matched with the lower pulley support in a rotating mode through lower pins, an upper pulley is arranged in an upper pulley support on the steel beam to be matched with the upper pulley support in a rotating mode through upper pins, and a rope connected with the lower portion of the steel beam winds through the lower portion of the lower pulley and the upper portion of the upper pulley to be connected with a lift car. On one hand, when the lift car goes upwards, the plunger post and a lower pulley block move downwards under the effect of gravity, part of weight of the lift car is counteracted, power dissipation of the hydraulic cylinder is effectively reduced, operation cost is saved, and when the lift car goes downwards, due to the fact that the weight of the lift car is larger than the weight of the plunger post and the lower pulley block, the lift car moves downwards under the effect of gravity; on the other hand, when the lift car goes upwards, the steel beam only bears weight of the lift car and the hydraulic cylinder, pull force of the hydraulic cylinder pulling the rope acts on the steel beam in a reverse mode, the steel beam does not need to bear the pull force, and force borne by the steel beam is reduced.

Description

technical field [0001] The invention relates to an elevator, in particular to an upside-down side-mounted hydraulic freight elevator. Background technique [0002] The rope of the side-mounted hydraulic elevator is generally connected to one side of the car, and its basic structure consists of a hydraulic cylinder, a pulley arranged on the hydraulic plunger, a rope matched with the pulley, and a car connected to the side of the rope. The hydraulic cylinders of the prior art hydraulic elevators are installed on the ground, and when the plunger rod in the hydraulic cylinder moves from bottom to top, the car and goods are transported from the bottom layer to the high floor. Active force, one is the gravity of the car, and the other is the gravity of the plunger rod. Because the hydraulic cylinder is large, the weight of the plunger rod reaches several hundred kg to thousands of kg. The disadvantages are high power consumption and high operating costs.
