Description

Technical Field

[0001] The utility model belongs to the technical field of lifting platforms, and in particular relates to a track self-propelled lifting platform. Background Art

[0002] Lifting platforms are often used in many fields such as industrial production, logistics warehousing, and construction to lift people and goods to different heights to meet the needs of production operations, cargo handling, and construction.

[0003] In order to facilitate movement and transfer of work areas, the bottom of the existing lifting platform is generally provided with rotating rollers at the bottom of the lifting platform to push the lifting platform to move. However, when the rollers of the traditional mobile lifting platform roll on the ground, they have extremely high requirements on the flatness of the ground. In many workplaces, such as old factory workshops, outdoor temporary work sites, etc., the ground is often uneven, bumpy or has a certain slope, which makes the rollers prone to jamming and bumping during movement, which not only affects the moving speed and precise positioning of the platform, but may also cause safety accidents such as cargo falling, equipment damage and operator injury, thereby making the lifting platform less stable and inconvenient to use.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The utility model provides Figure 1-2 A track-type self-propelled lifting platform is shown, comprising:

[0020] A base 1, a first lifting platform 2 is provided on the top of the base 1 and a second lifting platform 19 is provided on the top of the first lifting platform 2, a plurality of first X-shaped cross rods 3 and a second X-shaped cross rod 11 are rotatably connected on both sides of the surface of the base 1, the top of the first X-shaped cross rod 3 is rotatably connected to the first lifting platform 2, and the top of the second X-shaped cross rod 11 is rotatably connected to the second lifting platform 19, a plurality of groups of hydraulic cylinders 4 are rotatably connected on the surface of the base 1 and the piston rods of the plurality of groups of hydraulic cylinders 4 are rotatably connected to one end of the first X-shaped cross rod 3 and the second X-shaped cross rod 11 respectively, two groups of support rods 16 are connected on both sides of the base 1, and the two ends of the two groups of support rods 16 are rotatably connected to the intersection of the first X-shaped cross rod 3 and the second X-shaped cross rod 11 respectively, a moving component is provided at the bottom of the base 1, and the reducer 5 of the moving component drives the chain 6 and the rail wheel 7 to transmit, so that the rail wheel 7 drives the base 1 to move.

[0021] The moving assembly includes a driving sprocket 8 and a driven sprocket 9. The reducer 5 is arranged in the base 1 and the output shaft of the reducer 5 is connected to the driving sprocket 8. The bottom of the base 1 is rotatably connected to the driving shaft 10 through a bearing.

[0022] The track wheels 7 are provided in several groups and the several groups of track wheels 7 are fixedly sleeved on the surface of the drive shaft 10, the driven sprocket 9 is fixedly sleeved on the surface of the drive shaft 10 and the driving sprocket 8 and the driven sprocket 9 are connected by a chain 6. The output shaft of the reducer 5 drives the driving sprocket 8 to rotate, and the driving sprocket 8 transmits power to the driven sprocket 9 through the chain 6, so that the track wheel 7 can be driven to roll on the track 18 through the driven sprocket 9.

[0023] A rotating shaft is rotatably connected to the bottom of the base 1 and located on one side of the driving shaft 10 through a bearing, and a plurality of rear wheels 12 are fixedly sleeved on the surface of the rotating shaft.

[0024] The bottom of the base 1 is connected to a drag chain 13, which can expand and contract as the platform moves, protecting the electrical lines and hydraulic pipelines connected to the platform and ensuring the normal operation of the equipment.

[0025] The surfaces of the first lifting platform 2 and the second lifting platform 19 are both connected with guardrails 14. When the lifting platform is raised or lowered, the guardrails 14 can play the most basic safety protection role. In addition, the first lifting platform 2 and the second lifting platform 19 are also rotatably connected with ladders 15 on both sides, and workers can enter the lifting platform through the ladders 15 to perform operations.

[0026] When the platform height needs to be raised, one of the hydraulic cylinders 4 is started and the piston rod of the hydraulic cylinder 4 is extended. Since the piston rods of the two hydraulic cylinders 4 are respectively connected to one end of the first X-shaped cross tie rod 3 and the second X-shaped cross tie rod 11, the extension of the piston rod will push the connection point between the first X-shaped cross tie rod 3 and the second X-shaped cross tie rod 11 and the base 1 to rotate. As the tie rod rotates, the connection point between its top and the first lifting platform 2 and the second lifting platform 19 will be lifted upward, thereby driving the first lifting platform 2 and the second lifting platform 19 to rise steadily. When the platform height needs to be lowered, the piston rod of the hydraulic cylinder 4 is retracted, the first X-shaped cross tie rod 3 and the second X-shaped cross tie rod 11 rotate in the opposite direction, and the first lifting platform 2 and the second lifting platform 19 then descend steadily under the action of gravity. Therefore, by controlling the extension and contraction amount of the piston rod of the hydraulic cylinder 4, the height of the lifting platform can be accurately controlled to meet the needs of different working heights.

[0027] When the platform needs to be moved, the reducer 5 can be started, and the output shaft of the reducer 5 drives the driving sprocket 8 to rotate. The driving sprocket 8 transmits power to the driven sprocket 9 through the chain 6. Since the driven sprocket 9 is fixedly mounted on the surface of the driving shaft 10, the driving shaft 10 rotates accordingly, and the plurality of track wheels 7 installed on the surface of the driving shaft 10 rotates together with the driving shaft 10, so that the track wheels 7 can roll on the track 18 set on the surface of the ground 17, and drive the base 1 and the entire lifting platform to move along the track 18;

[0028] The rear wheel 12 at the bottom of the base 1 plays an auxiliary supporting role. When moving in a straight line, the rear wheel 12 rolls with the track wheel 7, sharing part of the platform weight and reducing the wear of the track wheel 7. During the entire movement process, the drag chain 13 extends and contracts with the movement of the platform, protecting the electrical lines and hydraulic pipelines connected to the platform, etc., to ensure the normal operation of the equipment.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
