Description

Technical Field

[0001] The utility model relates to the technical field of flat elevators, and particularly relates to a flat elevator with high stability. Background Art

[0002] A flat elevator is an efficient and multifunctional logistics transportation device, which is widely used in multiple fields such as warehousing, production, retail, and healthcare. It mainly consists of a platform, a hydraulic mechanism, an electric control mechanism, and a support mechanism. The pressure generated by a hydraulic oil pump drives the hydraulic cylinder to work, realizing the lifting function of the platform;

[0003] Most of the existing flat elevators have a single set of hydraulic support mechanisms at the bottom to realize the lifting function of the supporting platform. Therefore, it is difficult for a single set of hydraulic support mechanisms to ensure that the lifting platform remains absolutely balanced when bearing heavy loads or eccentric loads. Due to uneven load distribution, the force on the hydraulic cylinder is prone to deviation, resulting in the platform shaking or tilting during the lifting process, thereby reducing the overall stability. Moreover, some of the supporting surfaces of flat elevators also have conveying structures such as balls or rollers to facilitate the pushing of items placed on the supporting platform. For example, when supporting and lifting and moving a board, after the board is stacked on the flat elevator and pushed with the help of balls or rollers, the board is prone to shift, causing the center of gravity of the supporting platform to change, and thus easily leading to the tipping of the flat elevator. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a flat elevator with high stability, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0025] Such as Figures 1-5As shown in the figure, the utility model provides a flat elevator with high stability, which includes a supporting platform 1 and a chassis 4. A top plate 2 is fixedly installed on the top of the supporting platform 1, and a plurality of rollers 3 are movably installed in the top plate 2. Two groups of hydraulic cross arms 5 are movably installed between the supporting platform 1 and the chassis 4. Side plates 7 are fixedly installed on both sides of the top plate 2, and a plurality of limiting mechanisms 8 are arranged between the top plate 2 and the side plates 7. The limiting mechanism 8 includes a mounting beam 9, a slider 10, a carrier plate 11 and a limiting shaft 12. The slider 10 is movably installed in the mounting beam 9, the carrier plate 11 is fixedly installed on the slider 10, the limiting shaft 12 is movably installed on the carrier plate 11, and the mounting beam 9 is fixedly installed in the top plate 2 and the side plates 7.

[0026] A plurality of second installation grooves 14 are formed on both sides of the top plate 2, and the second installation grooves 14 are located between two rollers 3. A plurality of first installation grooves 13 are formed on one side of the side plate 7, and the openings of the first installation grooves 13 are aligned with the corresponding second installation grooves 14. Based on this, with the arrangement of the first installation grooves 13 and the second installation grooves 14, the installation of the mounting beam 9 can be adjusted, and the top surface of the carrier plate 11 can be made flush with the top surface of the top plate 2.

[0027] As Figures 2-5 shown, a chute 15 is formed in the mounting beam 9. An end plate 16 is fixedly installed on one side of the mounting beam 9. A guide shaft 17 is fixedly installed in the end plate 16, and one side of the guide shaft 17 further extends into the chute 15 and is fixedly installed with a fixing block 18. The slider 10 is slidably installed in the chute 15, and the lower part of the slider 10 is also inserted and installed on the guide shaft 17. A compression spring 19 is sleeved on the guide shaft 17 between the end plate 16 and the slider 10. One side of the bottom of the mounting beam 9 is fixedly installed at the bottom of the second installation groove 14, and the top of the end plate 16 is fixedly installed at one side of the bottom of the side plate 7. Based on this, the slider 10 is slidably installed in the chute 15, and the guide shaft 17 and the compression spring 19 can be used to apply a reverse force to the carrier plate 11 and the limiting shaft 12 after they are displaced by force. A shaft seat 20 is fixedly installed on one side of the bottom of the carrier plate 11, and a guide plate 21 is fixedly installed on one side of the top of the carrier plate 11. Based on this, through the arrangement of the guide plate 21, the plates placed on the top plate 2 can be guided and the displacement of the limiting shaft 12 can be realized. A fixing shaft 22 is fixedly installed at the bottom of the limiting shaft 12, a rotating groove 23 is formed on the outer side of the limiting shaft 12, a support rod 24 is further arranged on the outer side of the limiting shaft 12, a sleeve 25 is fixedly installed at the top of the support rod 24, the bottom of the support rod 24 is fixedly installed on one side of the top of the carrier plate 11, and a plurality of support rods 24 are fixedly connected by a connecting rod 6. The fixing shaft 22 at the bottom of the limiting shaft 12 passes through the carrier plate 11 and is rotatably installed in the shaft seat 20, and the limiting shaft 12 is also rotatably installed in the sleeve 25 through the rotating groove 23. Based on this, through the rotating limiting shaft 12, the positioning and conveying of plates with different sizes can be realized in cooperation with the slider 10 and the compression spring 19.

[0028] It should be noted that the present utility model is a flat elevator with high stability. When placing a sheet on the top plate 2, a forklift can enter the sheet from one side of the top plate 2 to above the top plate 2, and the sheet at the lower position will squeeze the two guide plates 21 to one side respectively. As a result, the two guide plates 21 drive the corresponding carrier plates 11 to move to one side respectively. Then, the carrier plates 11 drive the limit shafts 12 and the sliders 10 to move to one side synchronously, and the bottom of the slider 10 slides in the chute 15. Moreover, the slider 10 also slides on the slider 10 through the through hole at the bottom and compresses the compression spring 19 outside the guide shaft 17 towards the end plate 16. At the same time, the limit shaft 12 drives the support rod 24 to move synchronously, and further enables the current support rod 24 to drive multiple support rods 24 to move synchronously through the connecting rod 6, so as to realize the synchronous movement of multiple limit shafts 12 to one side. Then, the sheet enters between the top plate 2 and the multiple limit shafts 12, and with the stretching and rebounding force of the compression spring 19, it presses on the slider 10 and the carrier plate 11 in the reverse direction, so that the multiple limit shafts 12 position the sheet on the top plate 2. When it is necessary to place the sheets on the top plate 2 one by one, the multiple limit shafts 12 can be displaced by squeezing with the first sheet in the same way as above, and the multiple limit shafts 12 position the first sheet at the middle position on the top plate 2 by means of the acting force of the corresponding compression springs 19 respectively, so as to realize the positioning placement of the subsequent sheets, and further prevent the offset of the sheets during placement and pushing.
