Description

Technical Field

[0001] The present invention belongs to the technical field of elevators, and particularly relates to an elevator. Background Art

[0002] At present, the elevator structure for a lifting roller bed mostly includes a motor, two output shafts, and two lifting towers. A camshaft is respectively arranged in each of the two lifting towers. The power of the motor drives the two camshafts to rotate through the two output shafts and a gear transmission structure. A spiral curve groove is arranged on the camshaft, and a cam follower is fitted and installed in the spiral curve groove. The cam follower can roll in the spiral curve groove, and the cam follower is connected to the roller bed surface of the lifting roller bed. When the camshaft rotates, the cam follower rolls along the spiral curve groove, thereby driving the roller bed surface to rise or fall to meet the production requirements.

[0003] However, in this elevator structure, since the lifting or lowering of the roller bed surface is solely completed by two cam followers, and the roller bed surface itself is relatively heavy, in order to improve the stability of the cam followers supporting the roller bed surface, it is necessary to increase the sizes of the camshaft and the cam followers, resulting in a large volume of the elevator and being inconvenient for space layout. Summary of the Invention

[0004] In view of this, the present invention aims to provide an elevator to simplify the elevator structure and ensure the stability of the elevator in lifting the roller bed surface.

[0005] To achieve the above object, the technical solution of the present invention is realized as follows:

[0006] An elevator for lifting a roller bed surface includes a support block and two guide seats. The two guide seats are arranged on a base. The roller bed surface and the support block are arranged one above the other between the two guide seats. The support block is linearly movable between the two guide seats. The base is provided with a power element for pushing the support block to move. The roller bed surface is connected to the support block through several parallel swing arms, and a sliding connection structure is vertically arranged between the roller bed surface and the two guide seats.

[0007] Further, the sliding connection structure includes a chute vertically opened on the side surface of the guide seat facing the roller bed surface, and a slider provided corresponding to the chute on the guide seat. The slider and the chute are assembled and connected.

[0008] Further, the chute is a dovetail groove, and the slider is a corresponding dovetail slider.

[0009] Further, two slide rails are arranged side by side on the base, and the support block is slidably arranged on the two slide rails.

[0010] Further, two of the support blocks are arranged side by side, each slidably arranged on a slide rail, and the front and rear ends of the two support blocks are respectively connected by a connecting block, and one of the connecting blocks is connected to the push rod of the power element, and the power element is arranged between the two support blocks.

[0011] Further, the power element is a jack.

[0012] Compared with the prior art, the elevator of the present invention has the following advantages:

[0013] (1) The structure of the present invention is compact and occupies a small space. The roller bed tabletop is supported by several swing arms on the slidably arranged support blocks, which improves the support stability of the elevator for the roller bed tabletop and improves the lifting stability of the roller bed tabletop by the elevator.

[0014] (2) In the present invention, two support blocks are provided and connected by a connecting block, and one of the connecting blocks is connected to the power element, and the power element is arranged between the two support blocks, which further improves the overall structural compactness of the elevator of the present invention.

[0024] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0025] As Figure 1 、 Figure 2 shown, a lift is used to lift the roller bed table 1. The roller bed table 1 is a prior art and will not be described in detail here. The present invention includes a support block 4 and two guide seats 2. The two guide seats 2 are arranged on the foundation 9. The roller bed table 1 and the support block 4 are arranged one above the other between the two guide seats 2. The support block 4 is linearly movably arranged between the two guide seats 2. The foundation 9 is provided with a power element 8 for pushing the support block 4 to move. The power element 8 is preferably a jack. The roller bed table 1 is connected to the support block 4 through several parallel swing arms 3, and a sliding connection structure is vertically arranged between the roller bed table 1 and the two guide seats 2.

[0026] In the present invention, the jack drives the support block 4 to move. Since a sliding connection structure is vertically provided between the roller bed table 1 and the guide seat 2 to prevent the roller bed table 1 from moving laterally with the support block 4, when the support block 4 moves, several swing arms 3 will swing in the same direction simultaneously, causing the roller bed table 1 to rise or fall. Since both the swing arms 3 and the support block 4 are arranged under the roller bed table 1, the structure of this elevator is compact, occupies a small foundation area, and is convenient for layout. At the same time, since the roller bed table 1 is supported by several swing arms 3, the stability of lifting and lowering the roller bed table 1 of this elevator is improved.

[0027] In the present invention, the sliding connection structure between the roller bed table 1 and the guide seat 2 includes a chute 21 vertically opened on the side of the guide seat 2 facing the roller bed table 1, and a slider 11 provided corresponding to the chute 21 on the guide seat 2. The slider 11 and the chute 21 are assembled and connected. The chute 21 is preferably a dovetail groove, and the slider 11 is a corresponding dovetail slider, which improves the running smoothness of the sliding connection structure.

[0028] In the present invention, two slide rails 5 are arranged side by side between the two guide seats 2 in the foundation 9, as Figure 3 shown. The support block 4 is a rectangular block structure, and two are arranged side by side, and each is slidably connected to a slide rail 5. The front and rear ends of the two support blocks 4 are respectively connected by a connecting block 7. One of the connecting blocks 7 is connected to the push rod of the power element 8, and the power element 8 is arranged between the two support blocks 4. This structure further improves the compactness of the elevator structure described in the present invention.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
