DETAILED DESCRIPTION

[0028] The invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Embodiment 1: An indoor split-level telescopic track material lifting lift, such as Figure 1-Figure 2 As shown, the lifting trolley includes a base 10, a telescopic bracket 13 and a working platform 14. The lower end of the base 10 of the lifting trolley is provided with wheels 11 for easy walking. The periphery of the working platform 14 is provided with a guardrail 15 to prevent the staff from falling from a high altitude. The control box 16 of the lifting trolley is fixed on the guardrail 15 to facilitate the staff to control the lifting of the lifting trolley. The structure of the lifting trolley is existing.

[0030] like Figure 1-Figure 2 As shown, a telescopic track arranged in the vertical direction is provided between the base 10 and the lifting work platform 14, and the telescopic track includes a first track 21 arranged in the vertical direction fixed on the base 10, and a rectangular frame-shaped fixed frame 26 arranged in the vertical direction is fixed on the front side guardrail 15 of the work platform 14, and a notch is provided at the position where the lower end of the fixed frame 26 is aligned with the first track 21, and the notch is located at the left end of the lower frame of the fixed frame 26, and a slide rail 24 arranged in the horizontal direction is provided inside the fixed frame 26, and 8 second tracks 25 arranged in the vertical direction are slidably connected to the slide rail 24, and a first spring is fixed on the vertical frame on the right side of the fixed frame 26, and the first spring can only be extended and retracted in the horizontal direction, and the left end of the first spring is fixed to a second track 25 closest to the first spring, and the second track 25 closest to the first spring can only slide to the left to the top of the notch, and cannot slide down out of the fixed frame 26. The structures of the first track 21 and the second track 25 are exactly the same, and only the length is different, and the notch allows only the first track 21 or one second track 25 to pass through at a time.

[0031] When the lifting trolley is retracted, the first track 21 passes through the gap and extends into the fixed frame 26. When the lifting trolley is lifted upward, the upper end of the first track 21 gradually detaches downward from the fixed frame 26. When the first track 21 is completely detached from the fixed frame 26, all the second springs 31 slide to the left under the elastic force of the first spring until the second track 25 adjacent to the first track 21 slides to the left side of the fixed frame 26. When the first track 21 is completely detached from the fixed frame 26, the upper end of the first track 21 is engaged with the lower end of the second track 25 adjacent to the first track 21. When the lifting trolley continues to rise, the second track 25 adjacent to the first track 21 gradually slides downward out of the fixed frame 26, and so on, thereby realizing the automatic extension of the telescopic track.

[0032] like Figure 5-Figure 7 As shown, the upper end surface of the first track 21 and the lower end surface of the second track 25 are set as inclined surfaces inclined toward the upper left, and the bottom of the second track 25 is provided with a first cavity, and a first fixing plate 30 arranged in the horizontal direction is fixed inside the first cavity, and a second spring 31 that can extend downward is fixed to the lower end of the first fixing plate 30, and a first "7"-shaped first latch 32 is fixed to the lower end of the second spring 31, and a first through hole 33 arranged along the left and right directions is provided at the lower part of the first latch 32. When the second track 25 is located inside the fixing frame 26, the first latch 32 is fixed in the fixing frame 26. The second spring 31 is compressed by the squeezing of the lower frame of the frame 26, and the lower end of the first latch 32 abuts against the lower frame of the fixed frame 26; the lower end of the second track 25 is provided with a second through hole allowing the first latch 32 to pass through, and an L-shaped first limiting plate 35 is hinged on the left side wall in the first cavity, and the upper end of the first limiting plate 35 is connected to the left side wall of the first cavity through a third spring 34, and a fourth spring 36 that can be extended upward is provided above the horizontal end of the first limiting plate 35, and a third through hole allowing the first limiting plate 35 to rotate is provided on the left side wall of the second track 25; like Figure 5-Figure 7 As shown, a second cavity is provided at the top of the first track 21, a second fixing plate 40 arranged in the horizontal direction is fixed inside the second cavity, a fifth spring 41 which can be extended and retracted vertically upward is provided at the upper end of the second fixing plate 40, a second latch 42 which is vertically upward is fixed at the upper end of the fifth spring 41, a fourth through hole which passes through the upper end of the first track 21 and allows the first latch 32 to pass through is provided at the top of the second cavity, a second limiting plate 43 in the shape of "7" is hinged on the left side wall in the second cavity, the horizontal end of the second limiting plate 43 is buckled on the upper end of the second latch 42, and the upper part of the second limiting plate 43 is connected to the left side wall of the second cavity by a sixth spring 44; a fifth through hole which allows the second limiting plate 43 to rotate is provided on the left side wall of the first track 21; the horizontal end of the second limiting plate 43 is arc-shaped, and the lower end of the first latch 32 and the upper end of the second latch 42 are also arc-shaped; like Figure 5-Figure 7 As shown, when the first rail 21 and the second rail 25 are aligned, the first latch 32 and the second latch 42 are aligned up and down; when the first latch 32 breaks away from the restriction of the fixed frame 26 and moves downward under the action of the second spring 31, the first latch 32 can squeeze the second limiting plate 43 to make the second limiting plate 43 rotate counterclockwise, and when the first latch 32 continues to move downward until the horizontal end of the second limiting plate 43 is aligned with the first through hole 33, the horizontal end of the second limiting plate 43 can be inserted into the first through hole 33 to limit the first latch 32; thereby realizing the clamping connection between the first rail 21 and the second rail 25.

[0033] like Figure 8-Figure 11 As shown, when the lifting trolley is retracted, the staff manually installs a squeezing rod 50 arranged vertically downward on the left side frame of the fixed frame 26, and the working platform 14 drives the squeezing rod 50 to move downward. When the portion of the first limit plate 35 located outside the third through hole is subjected to the downward squeezing force of the squeezing rod 50 and rotates toward the inside of the first cavity, the fourth spring 36 is compressed by the first limit plate 35 and the first latch 32, and the fourth spring 36 gives the first latch 32 an upward force; since the first latch 32 is limited by the second limit plate 43, the first latch 32 does not move temporarily. When the squeezing rod 50 continues to move downward and causes the portion of the second limit plate 43 located outside the fifth through hole to be subjected to the downward squeezing force and rotate toward the inside of the second cavity, the second limit plate 43 rotates counterclockwise and disengages from the first blind hole. At this time, the first latch 32 slides upward out of the first track 21 under the action of the fourth spring 36, thereby realizing the separation of the first track 21 and the second track 25.

[0034] In this embodiment, the structure of the upper ends of all the second rails 25 is the same as that of the upper ends of the first rails 21, and the structure of the lower ends of all the second rails 25 is the same. During the contraction of the telescopic rail, since the upper and lower end surfaces of the second rails 25 are both inclined surfaces, when the fixed frame 26 presses the uppermost second rail 25 downward, the second rail 25 will slide to the right into the fixed frame 26, and so on, so that all the second rails 25 are recovered into the fixed frame 26, and finally the upper end of the first rail 21 is also stored in the fixed frame 26. After the telescopic rail is contracted, the squeezing rod 50 is manually removed for standby use.

[0035] like Figure 3-Figure 4As shown, a first slide groove arranged in the vertical direction is provided on the front side surface of the first track 21 and the second track 25, and a block 27 is slidably connected in the first slide groove. The block 27 is stuck in the first slide groove and can only slide up and down along the first slide groove. A material platform 23 arranged in the horizontal direction is fixed on the front end surface of the block 27; a motor is fixed on the block 27, and a gear 22 is connected to the output shaft of the motor. A second slide groove arranged in the vertical direction is provided on the right side surface of the first track 21 and the second track 25, and a rack 28 matching the gear 22 is fixed at the bottom of the second slide groove; the motor drives the gear 22 to rotate forward when it rotates forward, and the gear 22 moves upward along the rack 28, and the gear 22 drives the motor, the block 27 and the material platform 23 to move upward; the motor drives the gear 22 to reverse when it rotates reversely, and the gear 22 rotates downward along the rack 28, and the gear 22 drives the motor, the block 27 and the material platform 23 to move downward, thereby realizing automatic lifting of the material. In this embodiment, a shaft lock is provided between the motor shaft and the gear 22 to ensure that the gear 22 can be locked after the motor stops running, thereby preventing the gear 22 from falling due to gravity, thereby stopping the material at the upper end of the telescopic track.

[0036] like Figure 1-Figure 2 As shown, a fixing plate 20 for parking a material platform 23 is fixed at the lower end of the first track 21 .

[0037] like Figure 1-Figure 2 As shown, there are two telescopic rails and they are symmetrically arranged on both sides of the lifting trolley, which can improve the efficiency of material lifting.

[0038] like Figure 1-Figure 2 As shown, the base 10 of the lifting trolley is provided with supporting legs 12 to prevent the entire trolley from tipping over.

[0039] The above description is only a specific implementation method of the invention, but the protection scope of the invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the invention, which should be covered within the protection scope of the invention. Therefore, the protection scope of the invention should be based on the protection scope of the claims.
