Abstract

The utility model provides a multi-air-cylinder synchronous hoisting device. The multi-air-cylinder synchronous hoisting device comprises a bottom board which is fixedly connected with air cylinders, the positions, corresponding to the air cylinders, of the bottom board are provided with guide rods, the top end of each guide rod is connected with a guide base through a bolt, and each guide base is connected with the end face of an air cylinder piston rod; the front end of each guide rod is of a gear structure; the bottom board is provided with bearing blocks provided with bearings, and the positions, corresponding to the corresponding guide rods, of the two ends of each bearing are respectively provided with a first gear which is meshed with a gear of the corresponding guide rod; the middle portion of each bearing is provided with a second gear, the end face of each second gear is meshed with a toothed bar, and each toothed bar is fixed on the bottom board through a toothed bar sliding base. Due to the fact that the gears arranged on the bearings are respectively and correspondingly meshed with the corresponding gears on the guide rods and the toothed bars, positions of the air cylinders are automatically regulated in an operation process, and the purpose of synchronous hoisting is achieved. The multi-air-cylinder synchronous hoisting device operates stably and is low in workload and cost.

Description

A kind of multiple-cylinder synchronous lifting device

Technical field

The utility model relates to mechanical equipment field, relates in particular to a kind of device that can carry out synchronous lifting that is made up of multiple-cylinder.

Background technology

Gas has compressibility as driving medium, is widely used in cylinder, and the trend of cylinder connecting line and length, have impact to the uninterrupted of gas, thereby directly has influence on the running velocity of cylinder.

For the bench board being formed by multiple-cylinder, often need multiple cylinders can synchronized operation, existing method is: the speed of adjusting each cylinder guarantees its synchronized operation with this, and the method efficiency is low, therefore weak effect needs prior art to improve.

Summary of the invention

For guaranteeing the synchronized operation of multiple-cylinder, realize the steady lifting to object, the utility model proposes a kind of synchronous lifting device being formed by multiple-cylinder.

For this reason, the technical solution of the utility model is: a kind of multiple-cylinder synchronous lifting device, comprise base plate, on base plate, be fixedly connected with cylinder, position corresponding with cylinder on base plate is also provided with pilot bar, the top of pilot bar is connected with guide holder by bolt, and guide holder is connected with the end face of cylinder piston rod, it is characterized in that: the front end of described pilot bar is gear structure; Described base plate is provided with bearing seat, and bearing seat is provided with bearing, is respectively equipped with gear one at the two ends of bearing and the correspondence position of pilot bar, and gear one is connected with a joggle with the gear on pilot bar; Be provided with gear two at the midway location of bearing, the end face of gear two tooth bar that has been connected with a joggle, described tooth bar is fixed on base plate by tooth bar slide.

Principle of work:

While using this device, weight is placed on guide holder, starts cylinder.Cylinder piston rod promotes guide holder up-and-down movement, and guide holder drives pilot bar motion, and the up-and-down movement of pilot bar drives bearing to rotate, and drives the tooth bar moving linearly of below in bearing rotation process by its intermediate gear.Because three gears share an axle, therefore, in the time that multiple cylinder movings are asynchronous, by the automatic adjustment of rack-and-gear, the motion of each cylinder reached synchronously, thereby weight is steadily given rise to certain height.

Beneficial effect:

The utility model, by multiple gears are housed on a bearing, and is connected with a joggle each gear respectively with corresponding pilot bar gear and tooth bar, make automatic adjusting position in cylinder operational process, reaches the object of synchronous lifting.This device operates steadily, and work capacity is little, and cost is low.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is left view of the present utility model;

Number in the figure is: 1, base plate; 2, cylinder; 3, pilot bar; 4, bolt; 5, guide holder; 6, cylinder piston rod; 7, bearing seat; 8, bearing; 9, gear one; 10, gear two; 11, tooth bar; 12, tooth bar slide.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1 and Figure 2, a kind of multiple-cylinder synchronous lifting device, comprises base plate 1, is fixedly connected with cylinder 2(and can arranges as required the cylinder of varying number on base plate 1, and the present embodiment is take four cylinders as example); Position corresponding with cylinder 2 on base plate 1 is also provided with pilot bar 3, and the top of pilot bar 3 is connected with guide holder 5 by bolt 4, and guide holder 5 is connected with the end face of cylinder piston rod 6; The front end of described pilot bar 3 is gear structure; On base plate 1, be welded with bearing seat 7, bearing 8 is housed on bearing seat 7, at the two ends of bearing 8 and the correspondence position of pilot bar 3, gear 1 is housed respectively, gear 1 is connected with a joggle with the gear position of pilot bar 3 front ends; Midway location at bearing 8 is also equipped with gear 2 10, the end face of gear 2 10 tooth bar 11 that has been connected with a joggle, and this tooth bar 11 is fixed on base plate 1 by tooth bar slide 12.

While using this device, weight is placed on guide holder, starts cylinder.Cylinder piston rod promotes guide holder up-and-down movement, and guide holder drives pilot bar motion, and the up-and-down movement of pilot bar drives bearing to rotate, and drives the tooth bar moving linearly of below in bearing rotation process by its intermediate gear.Because three gears share an axle, therefore, in the time that multiple cylinder movings are asynchronous, adjust the motion of each cylinder is reached synchronously by the east, village of rack-and-gear, thereby weight is steadily given rise to certain height.
