Abstract

The utility model discloses a mechanical elevating apparatus which can be used for manpower transporting tools like a manpower fork truck, a small wheelbarrow, etc. The utility model comprises a machine frame, a winching drum wheel which is arranged on the machine frame and is provided with a ratchet wheel, a rocker arm for controlling the unidirectional rotation of the winching drum wheel, and a ratchet pawl, wherein, the winching drum wheel is wound with a drag rope which passes through a balance block connected with a release link, then the front end and the back end of the drag rope are connected together, and the drag rope is connected with a connecting rod fixed on a hoisting block coaxially with the winching drum wheel; the balance block is connected with one end of a balance spring, and the other end the balance spring is connected with the machine frame; the hoisting block is connected with a push lifting column driving load to move up and down through a load rope. The utility model has the advantages of simple structure, small size, light weight, less abrasion of the drag rope, simple and convenient lifting operation, no oil leakage fault, convenient maintenance and low cost.

Description

The mechanical ascending and descending device
Technical field
The utility model relates to a kind of device that is used for the lifting weight.
Background technology
People are the normal jacking system that adopts on equipment such as artificial fork truck, waggon, and it just can promote heavier goods with less power.But jacking system commonly used is a hydraulic structure, and oil leakage fault is often arranged, and makes troubles to use.The applicant's the patent No. is that 87208417 utility model discloses a kind of simple and easy fork truck, the characteristics of this fork truck are that it has rocking bar, bob-weight and can make elevating drum only make transmission device and the back-stop mechanism of folk prescription to rotation, steel rope is wrapped on the elevating drum, and two ends are hanging goods shovel and bob-weight respectively.The shortcoming of this structure is by cable wire direct pull weight, require cable wire thick, from great, it also needs to join a bob-weight, has strengthened the weight of whole device.
Summary of the invention
The purpose of this utility model just provides a kind of simpler mechanical ascending and descending device of structure that can be applied on the artificial transportation means such as artificial fork truck, waggon.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: this mechanical ascending and descending device remains according to Euler's formula F=T/e K α rPrinciple design, it comprises frame, is contained in the elevating drum of being with ratchet on the frame, the rocking arm and the ratchet of control elevating drum unidirectional rotation, be wound with drag-line on the elevating drum, the head and the tail two ends are connected behind described guy cable rounds and the equalizer pulley that reset lever links to each other, and this drag-line also is fixed on connecting rod on the coaxial gin wheel of elevating drum and links to each other with one; This equalizer pulley connects an end of balance spring, and the other end of balance spring links to each other with frame; The jacking post that this gin wheel is done dipping and heaving by load rope and drive load links to each other.
Use jacking system of the present utility model, shake rocking arm, the fermented soya beans, salted or other wise wheel rotates, because the setting of ratchet, the assurance elevating drum is only made unidirectional rotation and can not reversed.When elevating drum rotated, connecting rod rotated around drum axle with drag-line, drove gin wheel and rotated, thereby affect the jacking post up to promote by the load rope.Because the effect of balance spring pulling force, elevating drum are in rotating process, drag-line keeps tightening, and equalizer pulley equates that with the linear velocity of elevating drum drag-line is in state of equilibrium all the time.When the jacking post rises to desired height, stop to shake rocking arm, the jacking post just is parked on this height.When needs lower the jacking post, pull reset lever, it is close to the elevator pulley that equalizer pulley overcomes the pulling force of balance spring, the drag-line lack of equilibrium, under the gravity of jacking post self, the load rope affects connecting rod and drag-line, and the friction force that overcomes between drag-line and the elevating drum back slides, thereby the jacking post is lowered.
The utility model is simple in structure, and volume is little, and is in light weight, and drag-line is directly lifting not, but the pulling gin wheel by gin wheel pulling load rope, drives the jacking post again, and the load rope can be a chain, thereby reduce the gin wheel diameter, alleviate elevating drum and drag-line load, dwindled volume.And drag-line wearing and tearing are little, and descending operation is easy, does not have oil leakage fault, and is easy to maintenance, with low cost, can be widely used on the artificial transportation means such as manual transport trolley.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described specifically.
Fig. 1 is the structural representation that the utility model mechanical ascending and descending device is contained in the embodiment on the manual transport trolley.
Fig. 2 is the structural representation of another embodiment.
The specific embodiment
As shown in Figure 1, the elevating drum 2 of band ratchet 1 is installed on the frame 3, and the Rocker arm 5 control elevating drum 2 of band ratchet 4 can only be made unidirectional rotation.Drag-line 6 on the elevating drum 4 around on also walk around an equalizer pulley 7 after a few, the head and the tail two ends of drag-line 6 are connected on the connecting rod 8.This connecting rod 8 is fixed on the gin wheel 10, and this gin wheel 10 is coaxial with elevating drum 2.Connect load rope 11 on the gin wheel 10, this load rope can be cable wire or chain, and load rope 11 links to each other with the jacking post 9 that the drive weight is done dipping and heaving.Equalizer pulley 7 also is connected with a balance spring 15, and the other end of balance spring 15 is fixed on the frame 3.A hinged reset lever 12 on the frame 3, reset lever 12 is connected on the equalizer pulley 7 by steel wire 14, fixed pulley 13.Also be provided with a vertical position-limited trough 16 on frame 3, the wheel shaft of equalizer pulley 7 is limited in wherein, can only move up at upper and lower.Certainly, this position-limited trough 16 also can be replaced by the fork 17 that one one end is hinged on the relative side of frame 3 and fixed pulley 13, the other end is hinged on the equalizer pulley 7, as shown in Figure 2.When pulling reset lever 12, equalizer pulley 7 is up carried, drag-line 6 lack of equilibrium.
The swing Rocker arm 5, elevating drum 2 clickwises, connecting rod 8 is with drag-line 6 clickwises, and load rope 11 hauls the jacking post and up promotes.When rising to desired location, Rocker arm 5 stops swinging, and elevating drum 2 can not reverse under the effect of ratchet 1 ratchet 4; Under the effect of balance spring 15, drag-line 6 is in state of equilibrium, connecting rod 8 transfixions, and jacking post 9 just is parked on this height.Step on reset lever 12, equalizer pulley 7 is up carried, drag-line 6 lack of equilibrium, and under the effect of self gravitation, the jacking post is got back to original height.
