Description

Car door lifting mechanism

Technical Field

The utility model relates to the technical field of elevators, in particular to a car door lifting mechanism.

Background

With the development of industrial automation, car automatic door mechanisms are increasingly used in the industrial field as mechanisms for controlling material in and out.

The conventional automatic door lifting mechanism in the market at present controls the automatic door to lift by matching a motor with a synchronous belt, and the motor rotates to drive the synchronous belt to retract and retract, and the sliding rail is used as a guide mechanism of the automatic door, so that the defect is that the lifting synchronism of the automatic door cannot be ensured, and the use cost is high.

Disclosure of Invention

In order to solve the defects in the prior art, the utility model aims to provide the lifting mechanism for the car door, which can drive the automatic door to synchronously lift, thereby saving a great deal of cost.

The technical scheme adopted for solving the technical problems is as follows:

the car door lifting mechanism comprises a car frame, wherein an automatic door is arranged at the front end of the car frame, and is lifted through the lifting mechanism;

the lifting mechanism comprises an automatic sliding table arranged at the top end of the car frame, a movable pulley assembly is arranged on the automatic sliding table, and the movable pulley assembly can be driven to move through the operation of the automatic sliding table; the fixed pulley assembly is arranged at the front end of the movable pulley assembly;

one end of the synchronous belt is fixed on the car frame and between the two pulley assemblies, and the other end bypasses the movable pulley assembly and the fixed pulley assembly to be connected with the automatic door.

Further, sliding rails are arranged on two sides of the front end of the car frame, and the automatic door is in sliding connection with the sliding rails.

Further, the synchronous belt is fixed at the middle position of the lower end of the automatic door.

Further, two ends of the synchronous belt are respectively fixed through pressing plates.

Further, the automatic sliding table is an air cylinder sliding table.

Compared with the prior art, the utility model has the beneficial effects that:

1. according to the car door lifting mechanism, the automatic door is driven to move through the movement of the cylinder sliding table, so that the synchronism of automatic door lifting can be realized, and the asynchronous condition of automatic lifting is solved;

2. according to the car door lifting mechanism, when the cylinder sliding table moves by the distance of Xmm, the automatic door can be lifted by the distance of 2Xmm, short-stroke driving and large-stroke lifting are realized, and the use cost can be greatly saved.

Drawings

Other features, objects and advantages of the present application will become more apparent upon reading of the detailed description of non-limiting embodiments, made with reference to the following drawings, in which:

FIG. 1 is a schematic diagram of the structure of the present utility model;

fig. 2 is a front view;

fig. 3 is an enlarged view at a.

In the figure: the car comprises a 1-car frame, a 2-automatic door, a 3-cylinder sliding table, a 4-movable pulley assembly, a 5-fixed pulley assembly, a 6-synchronous belt, 7-sliding rails and 8-pressing plates.

Detailed Description

The present application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting of the utility model. It should be noted that, for convenience of description, only the portions related to the utility model are shown in the drawings.

It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1-2, the present embodiment provides a car door lifting mechanism, which comprises a car frame 1, wherein an automatic door 2 is arranged at the front end of the car frame 1, the automatic door 2 is lifted by the lifting mechanism, and the material inlet and outlet can be controlled by lifting the automatic door 2.

Specifically, as shown in fig. 3, the lifting mechanism comprises an automatic sliding table arranged at the top end of the car frame 1, a movable pulley assembly 4 is arranged on the automatic sliding table, and the movable pulley assembly 4 can be driven to move by the operation of the automatic sliding table; the car frame 1 is also provided with a fixed pulley assembly 5 positioned at the front end of the movable pulley assembly 4. One end of the synchronous belt 6 is fixed on the car frame 1 and between the two pulley assemblies, and the other end bypasses the movable pulley assembly 4 and the fixed pulley assembly 5 to be connected with the automatic door 2. In addition, the front end both sides of the car frame 1 are provided with slide rails 7, and the automatic door 2 is slidably connected with the slide rails 7. In this embodiment, the cylinder slip table 3 is used to the automatic slip table, and in the motion process, the automatically-controlled door 2 uses slide rail 7 as guiding mechanism, the removal of cylinder slip table 3 drives movable pulley assembly 4 motion, and the in-process of removal elongates hold-in range 6, when realizing that cylinder slip table 3 removes Xmm, automatically-controlled door 2 can promote 2Xmm, has solved the asynchronous situation of automatic promotion, has realized short stroke drive, large stroke promotion. In addition, the original lifting mode of the single-side air cylinder (namely, the air cylinder is arranged on one side of the automatic door) can cause the asynchronous lifting of the automatic door; if the double-sided cylinder lifting is adopted, the cost of one set of equipment is increased, and the cost is slightly higher than that of the embodiment; if motor driving is adopted, the cost is higher, and the structure of the lifting mechanism is simplified to the greatest extent, so that the use cost can be greatly saved while the lifting synchronism is ensured.

In addition, the synchronous belt 6 is fixed at the middle position of the lower end of the automatic door 2, and two ends of the synchronous belt 6 are respectively fixed through pressing plates 8.

The car door lifting mechanism of the embodiment realizes the synchronism of the lifting of the automatic door 2 and can effectively save the use cost.

It will be appreciated by persons skilled in the art that the scope of the utility model referred to in this application is not limited to the specific combinations of features described above, but it is intended to cover other embodiments in which any combination of features described above or equivalents thereof is possible without departing from the spirit of the utility model. Such as the above-described features and technical features having similar functions (but not limited to) disclosed in the present application are replaced with each other.
