Detailed Implementation

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

[0029] Example 1:

[0030] An indoor multi-level telescopic track material lifting and hoisting vehicle, such as Figures 1-2 As shown, the device includes a lifting trolley, which comprises a base 10, a telescopic support 13, and a work platform 14. The base 10 is equipped with wheels 11 for easy movement. The work platform 14 is surrounded by guardrails 15 to prevent workers from falling from heights. The control box 16 of the lifting trolley is fixed to the guardrails 15, allowing workers to control the lifting and lowering of the trolley. The structure of the lifting trolley is existing.

[0031] like Figures 1-2 As shown, a telescopic track arranged vertically is provided between the base 10 and the lifting work platform 14. The telescopic track includes a first track 21 arranged vertically and fixed to the base 10. A rectangular frame 26 arranged vertically is fixed to the front guardrail 15 of the work platform 14. A notch is provided at the lower end of the fixed frame 26, aligned with the first track 21. The notch is located at the left end of the lower frame of the fixed frame 26. A horizontal slide rail 24 is provided inside the fixed frame 26. Eight second tracks 25 arranged vertically are slidably connected to the slide rail 24. A first spring is fixed to the vertical frame on the right side of the fixed frame 26. The first spring can only extend and retract horizontally. The left end of the first spring is fixed to the second track 25 closest to the first spring. The second track 25 closest to the first spring can only slide to the left above the notch and cannot slide down out of the fixed frame 26. The first track 21 and the second track 25 have the same structure, only different lengths. Only one first track 21 or one second track 25 is allowed to pass through the notch at a time.

[0032] When the trolley is retracted, the first track 21 passes through the gap and extends into the fixed frame 26. When the trolley is raised, the upper end of the first track 21 gradually separates downward from the fixed frame 26. When the first track 21 is completely separated 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 separated from the fixed frame 26, the upper end of the first track 21 is connected with the lower end of the second track 25 adjacent to the first track 21. When the trolley continues to rise, the second track 25 adjacent to the first track 21 gradually slides out of the fixed frame 26. In this way, the telescopic track is automatically extended.

[0033] As shown in Figures 5-7 The upper end surface of the first track 21 and the lower end surface of the second track 25 are inclined upward to the left. The bottom of the second track 25 is provided with a first cavity. A first fixed plate 30 is arranged horizontally in the first cavity. The lower end of the first fixed plate 30 is fixed with a second spring 31 which can be extended downward. The lower end of the second spring 31 is fixed with a first pin 32 in the shape of "7". The lower part of the first pin 32 is provided with a first through hole 33 arranged along the left-right direction. When the second track 25 is located in the fixed frame 26, the first pin 32 is pressed by the lower edge of the fixed frame 26, so that the second spring 31 is compressed and the lower end of the first pin 32 abuts against the lower edge of the fixed frame 26. The lower end of the second track 25 is provided with a second through hole allowing the first pin 32 to pass through. An L-shaped first limiting plate 35 is hinged to the left side wall of the first cavity. The upper end of the first limiting plate 35 is connected with the left side wall of the first cavity through a third spring 34. The upper side of the horizontal end of the first limiting plate 35 is provided with a fourth spring 36 which can be extended upward. The left side wall of the second track 25 is provided with a third through hole allowing the first limiting plate 35 to rotate;

[0034] As shown in Figures 5-7As shown, the top of the first track 21 is provided with a second cavity, a second fixed plate 40 arranged in horizontal direction is fixed inside the second cavity, the upper end of the second fixed plate 40 is provided with a fifth spring 41 which can be vertically upwardly extended, the upper end of the fifth spring 41 is fixed with a second bolt 42 which is vertically upward, the top of the second cavity is provided with a fourth through hole which penetrates the upper end of the first track 21 and allows the first bolt 32 to pass through, a second limiting plate 43 in the shape of "7" is hinged on the left side wall of the second cavity, the horizontal end of the second limiting plate 43 is buckled on the upper end of the second bolt 42, and the upper part of the second limiting plate 43 is connected with the left side wall of the second cavity through a sixth spring 44; the left side wall of the first track 21 is provided with a fifth through hole which allows the second limiting plate 43 to rotate; the horizontal end of the second limiting plate 43 is in the shape of a circular arc, and the lower end of the first bolt 32 and the upper end of the second bolt 42 are also in the shape of a circular arc;

[0035] As shown in the figure, Figures 5-7 When the first track 21 and the second track 25 are aligned, the first bolt 32 and the second bolt 42 are aligned up and down; when the first bolt 32 moves downward under the action of the force of the second spring 31 during the process of getting rid of the restriction of the fixed frame 26, the first bolt 32 can extrude the second limiting plate 43 to make the second limiting plate 43 rotate counterclockwise, when the first bolt 32 continues to move downward to the position where 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 inside of the first through hole 33 to limit the first bolt 32; thereby realizing the clamping of the first track 21 and the second track 25.

[0036] As shown in the figure, Figures 8-11 When the lifting trolley is retracted, the worker manually installs an extrusion rod 50 arranged vertically downward on the left side frame of the fixed frame 26, the working platform 14 drives the extrusion rod 50 to move downward, when the part of the first limiting plate 35 located outside the third through hole is rotated to the inside of the first cavity under the extrusion force of the extrusion rod 50 downward, the fourth spring 36 is compressed by the first limiting plate 35 and the first bolt 32, and the fourth spring 36 gives the first bolt 32 an upward force; since the first bolt 32 is limited by the second limiting plate 43, the first bolt 32 does not act temporarily, when the extrusion rod 50 continues to move downward and the part of the second limiting plate 43 located outside the fifth through hole is rotated to the inside of the second cavity under the extrusion force, the second limiting plate 43 rotates counterclockwise and disengages from the first blind hole, at this time, the first bolt 32 slides upward out of the first track 21 under the action of the force of the fourth spring 36, thereby realizing the separation of the first track 21 and the second track 25.

[0037] In this embodiment, the upper end of all the second rails 25 is the same structure as the upper end of the first rail 21, and the lower end of all the second rails 25 is the same structure. During the contraction of the telescopic rail, because the upper end face and the lower end face of the second rail 25 are both inclined, when the fixed frame 26 extrudes the uppermost second rail 25 downward, the second rail 25 will slide to the inside of the fixed frame 26 to the right, and so on, realizing the recycling of all the second rails 25 into the fixed frame 26, and finally the upper end of the first rail 21 is also accommodated into the fixed frame 26. After the telescopic rail is contracted, the extrusion rod 50 is manually removed for standby.

[0038] As shown in Figures 3-4 , the front side of the first rail 21 and the second rail 25 is provided with a first sliding groove arranged in the vertical direction, a clamping block 27 is slidably connected in the first sliding groove, the clamping block 27 is clamped into the first sliding groove and can only slide up and down along the first sliding groove, and the front end face of the clamping block 27 is fixed with a material platform 23 arranged in the horizontal direction; a motor is fixed on the clamping block 27, a gear 22 is connected to the output shaft of the motor, a second sliding groove is arranged on the right side of the first rail 21 and the second rail 25 in the vertical direction, and a rack 28 cooperating with the gear 22 is fixed at the bottom of the second sliding groove; the motor drives the gear 22 to rotate forward, the gear 22 moves upward along the rack 28, and the gear 22 drives the motor, the clamping block 27 and the material platform 23 to move upward; the motor drives the gear 22 to rotate reversely, the gear 22 rotates downward along the rack 28, and the gear 22 drives the motor, the clamping block 27 and the material platform 23 to move downward, thereby realizing automatic lifting of the material.

[0039] In this embodiment, a shaft lock is arranged between the motor shaft and the gear 22 to ensure that the gear 22 can be locked after the motor stops running, preventing the gear 22 from falling due to gravity, so that the material can be stopped at the upper end of the telescopic rail.

[0040] As shown in Figures 1-2 , the lower end of the first rail 21 is fixed with a fixed plate 20 for parking the material platform 23.

[0041] As shown in Figures 1-2 , the number of telescopic rails is 2 and they are symmetrically arranged on both sides of the lifting trolley, which can improve the efficiency of material lifting.

[0042] As shown in Figures 1-2 , the base 10 of the lifting trolley is provided with a supporting leg 12 to avoid overall tilting.

[0043] The above merely describes specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application, therefore, the protection scope of the present application should be subject to the protection scope of the claims.
