The following describes the implementation of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations. Various details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

The utility model will be further described in detail below in conjunction with the accompanying drawings 1-3.

The embodiment of the utility model discloses a small maintenance lifting platform. Referring to Figures 1-3, the small maintenance lifting platform includes a main frame 1 and a working platform 2. The main frame 1 includes a movable support frame 11 and a movable frame 12 that can be retracted into the support frame 11. The bottom of the main frame 1 is provided with There are four lockable universal wheels. The working platform 2 is set on the mobile frame 12. The mobile frame 12 can be driven to move in the vertical direction to adjust the height of the working platform 2. When using it, the staff first enters the working platform. 2, the working platform 2 is moved upward to a suitable position by driving the moving frame 12.

The mobile frame 12 includes a first mobile frame 121 and a second mobile frame 122 that become smaller in order from bottom to top. The first mobile frame 121 is provided in the support frame 11 and can be driven to move upward to the upper end of the support frame 11 . The mobile frame 122 is arranged in the first mobile frame 121 and can be driven upward to the top of the first mobile frame 121. The working platform 2 is arranged on the second mobile frame 122; the main frame 1 is provided with mobile frames all around. 12. The driving member assembly 13 that moves up and down. The driving member assembly 13 includes a first electric push cylinder 131 for driving the first moving frame 121 to move up and down and a second electric push cylinder 132 for driving the second moving frame 122 to move up and down. The first electric push cylinder 131 is evenly arranged around the bottom of the support frame 11 in the vertical direction. The output end of the first electric push cylinder 131 is fixed around the top of the first moving frame 121. The second electric push cylinder 132 is arranged along the vertical direction. Evenly arranged around the first moving frame 121, the second electric push cylinder 132 is fixed around the top of the second moving frame 122, and the output end is set at the bottom of the first moving frame 121. By controlling the first electric push cylinder 131 and the third The two electric cylinders 132 can control the first moving frame 121 and the second moving frame 122 to move up and down, and can also make the first moving frame 121 and the second moving frame 122 more stable during the movement process.

In order to keep the first moving frame 121 and the second moving frame 122 balanced during the movement, balance members 16 are provided around the top and bottom of the first moving frame 121. In this embodiment, the balance members 16 are arranged in the horizontal direction. The channel steel on the first movable frame 121, and the channel steel on the top of the first movable frame 121 all extend outwards of the first movable frame 121, and the channel steel on the bottom of the first movable frame 121 extend inwards of the first movable frame 121. The top end of an electric push cylinder 131 is disposed on the balance member 16 at the top of the first moving frame 121, and the bottom end of the second electric push cylinder 132 is disposed on the balance member 16 at the bottom of the first moving frame 121. By moving the first electric push cylinder 131 and the second electric thrust cylinder 132 act on the balance member 16, so that the forces of the first electric thrust cylinder 131 and the second electric thrust cylinder 132 are more dispersed and the balancing effect is better.

At the same time, in order to make the mobile frame 12 more stable during the movement, the main frame 1 is provided with a first guide assembly 14 for guiding the movement of the first mobile frame 121 and a third guide assembly 14 for guiding the movement of the second mobile frame 122. Two guide assemblies 15. The first guide assembly 14 includes a first guide track 141 disposed around the support frame 11 in the vertical direction and a first guide bar 142 disposed around the first moving frame 121. The first guide bar 142 can be a One corresponding one moves up and down respectively along the first guide rail 141; the second guide assembly 15 includes a second guide rail 151 arranged around the first moving frame 121 in the vertical direction and a second guide arranged around the second moving frame 122. The strips 152 and the second guide strips 152 can move up and down along the second guide rail 151 respectively in one-to-one correspondence.

In order to avoid all gravity acting on the first electric thrust cylinder 131 and the second electric thrust cylinder 132 during use, causing damage to the first electric thrust cylinder 131 and the second electric thrust cylinder 132, the first guide rail 141 and the first electric thrust cylinder 132 are The guide bar 142 is provided with a plurality of first limiting holes 143 from bottom to top for fixing the first guide bar 142 in the first guide rail 141. The second guide bar 152 and the second guide rail 151 are both provided with a plurality of first limiting holes 143. A number of second limiting holes 153 are provided from bottom to top for fixing the second guide bars 152 in the second guide rail 151. When the working platform 2 is moved to a suitable position, a latch is used to pass through the first limiting holes 143 and The second limiting hole 153 fixes the first moving frame 121 and the second moving frame 122 so that the gravity exerted on the working platform 2 acts on the latch, preventing the first electric push cylinder 131 and the second electric push cylinder 132 from being used for a long time. Damage due to greater gravity.

Since some working floors are not horizontal, it is easy to cause the working platform to tilt, which will affect the operation of the staff. There are leveling parts 17 around the bottom of the support frame 11 for keeping the working platform 2 balanced. In this embodiment, leveling parts Part 17 uses telescopic shafts. The telescopic shafts are arranged on one side of the four universal wheels in the vertical direction. After locking the universal wheels, leveling is performed according to the levels around the equipment. By rotating and telescopically The rocker on the shaft will telescope out from the bottom of the telescopic shaft, and the shaft will hit the ground to level the working platform 2 until the levels around the working platform 2 show that the working platform 2 is in a horizontal state.

At the same time, in order to ensure the safety of workers during operation, the working platform 2 is provided with a guardrail 21. One end of the horizontal bar on one side of the guardrail 21 is hinged to the vertical bar, and the other end is set up on the arc-shaped channel steel provided on the vertical bar. Inside, the railing can be opened by turning the crossbar upward to facilitate workers to enter the working platform 2.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the present utility model can be modified. If the technical solution is modified or equivalently substituted without departing from the purpose and scope of the technical solution of the present utility model, it shall be covered by the claims of the present utility model.
