[0033] This embodiment provides a telescopic lift, which can be used in equipment handling operations, including but not limited to places such as nuclear power plants. For example, in a nuclear power plant, when carrying objects such as batteries, the handling efficiency can be effectively improved.

[0034] Please refer to Figures 1 to 3 As shown, the telescopic lifting vehicle in this embodiment includes a trolley 1, a lifting platform 2, a lifting mechanism 3, a loading platform 4, and a driving mechanism 5. One end of the lifting mechanism 3 is connected to the lifting platform 2, and the other end of the lifting mechanism 3 is connected to the trolley 1. The lifting mechanism 3 is used to drive the lifting platform 2 to move in the vertical direction; the loading platform 4 is slidably connected to the lifting platform 2 along a first direction, the first direction is perpendicular to the vertical direction, and the loading platform 4 is used to support an object; the driving mechanism 5 is transmission-connected to the loading platform 4 and installed on the lifting platform 2, and the driving mechanism 5 is used to drive the loading platform 4 to move in the first direction.

[0035] Specifically, in this embodiment, the trolley 1 includes a base 11, four moving wheels 12 and an armrest 13. The four moving wheels 12 are installed under the base 11, and the armrest 13 is installed on the base 11. The trolley 1 can be conveniently moved by the moving wheels 12 and the armrest 13 to improve the handling efficiency. A lifting mechanism 3 is installed on the trolley 1, and the lifting mechanism 3 is used to drive the lifting platform 2 to move in the vertical direction, thereby driving the loading platform 4 to move in the vertical direction, and the lifting mechanism 3 is used to realize the height position change of the loading platform 4 in the vertical direction. The loading platform 4 is slidably connected to the lifting platform 2, and the driving mechanism 5 is installed on the lifting platform 2. Therefore, the driving mechanism 5 can be used to drive the loading platform 4 to move in the first direction, and the driving mechanism 5 is used to realize the horizontal position change of the loading platform 4 in the first direction. The driving mechanism 5 can both extend the loading platform 4, thereby reducing the distance between the loading platform 4 and the object. After the loading platform 4 is moved under the object, the object can be directly moved onto the loading platform 4; and retract the loading platform 4. The loading platform 4 returns to the lifting platform 2 with the object, and finally drops the object through the lifting mechanism 3, thereby improving the object handling efficiency.

[0036] Alternatively, if Figure 1 and Figure 2 As shown, the telescopic lift vehicle further includes a fence 6, which is mounted on the loading platform 4. An opening is provided at one end of the fence 6 along the first direction, and the opening is used for objects to pass through. In this embodiment, a fence 6 is also installed on the loading platform 4, and the fence 6 can protect objects and prevent the objects from falling off the loading platform 4 during the movement of the device. An opening is provided on the fence 6 along one end of the first direction, and the opening enables the object to be moved to the loading platform 4 along the plane of the loading platform 4 without crossing the fence 6, thereby facilitating the transportation of objects and improving the transportation efficiency. The size of the opening is determined according to the size of the object and the structure around the object.

[0037] Furthermore, if Figure 1 and Figure 2As shown, the fence 6 includes a U-shaped limit plate 61 and a plurality of support rods 62, the plurality of support rods 62 are arranged at intervals and extend in the vertical direction, and the support rods 62 are respectively connected to the U-shaped limit plate 61 and the loading platform 4. In this embodiment, the fence 6 includes a U-shaped limit plate 61 and a plurality of support rods 62, and the plurality of support rods 62 connect the U-shaped limit plate 61 and the loading platform 4. The U-shaped limit plate 61 and the plurality of support rods 62 can play a limiting role, restrict the movement of the object, and save the manufacturing cost. In this embodiment, the support rod 62 can be threadedly connected to the loading platform 4, and the support rod 62 is passed through the U-shaped limiting plate 61 and the U-shaped limiting plate 61 is locked on the support rod 62 by a plurality of nuts; with such a configuration, the installation and subsequent maintenance of the fence 6 are more convenient, and the U-shaped limiting plate 61 can be adjusted in the vertical direction for the installation height, and the fixed position of the U-shaped limiting plate 61 can be determined according to the height size of the object, so that it can be used to limit objects of various different height sizes, thereby improving practicality.

[0038] Furthermore, if Figure 1 and Figure 2 As shown, the telescopic lift also includes a baffle 7, which is detachably connected to the fence 6 and is used to close or open the opening. In this embodiment, after the object enters the loading platform 4, a baffle 7 can be installed on the fence 6 to close the original opening, so that the fence 6 and the baffle 7 form a closed structure on the periphery of the object, restricting the object from moving out of the loading platform 4. After the object reaches the designated unloading position, the baffle 7 is removed from the fence 6 to open the opening, so that the object can be unloaded along the plane of the loading platform 4. Specifically, the baffle 7 is detachably connected to the U-shaped limit plate 61, and the connection method can be threaded connection, plug-in connection, etc., which is convenient for subsequent installation and disassembly.

[0039] As an alternative solution, the first end of the baffle 7 is pivotally connected to the fence 6 , and the second end is engaged by a lock, and the lock is used to lock or unlock the second end and the fence 6 .

[0040] Alternatively, if Figure 2 As shown, the loading platform 4 is provided with a supporting roller group 41, and the supporting roller group 41 includes a plurality of supporting rollers 411, and the plurality of supporting rollers 411 are arranged at intervals along the first direction, and the plurality of supporting rollers 411 form a supporting surface for supporting an object. Specifically, in this embodiment, the plurality of supporting rollers 411 are combined together to form a supporting surface, and the supporting surface can support the object, and when the object moves on the supporting surface, since the supporting rollers 411 can rotate themselves, the friction resistance between the object and the supporting rollers 411 can be reduced, and the effect of labor saving can be achieved when carrying the object.

[0041] Furthermore, if Figure 2As shown, there are multiple support roller groups 41, and the multiple support roller groups 41 are arranged at intervals along the second direction, and the first direction, the second direction, and the vertical direction are perpendicular to each other. In this embodiment, two groups of support roller groups 41 are arranged along the second direction, and the two groups of support roller groups 41 can better support the object and improve the labor-saving effect. However, when arranging the support roller groups 41, the number of support roller groups 41 is not limited to two groups, and the number can be more than two groups. The number of support roller groups 41 is determined according to actual conditions.

[0042] Alternatively, if Figure 3 As shown, the driving mechanism 5 includes a lead screw 51 and a slider 52, the slider 52 is threadedly connected to the lead screw 51 and fixedly connected to the loading platform 4, the axial direction of the lead screw 51 extends along the first direction, and the lead screw 51 is rotatably connected to the lifting platform 2. Specifically, in this embodiment, by rotating the lead screw 51, the slider 52 is moved along the first direction, and the slider 52 is fixedly connected to the loading platform 4, so the slider 52 can move along the first direction with the loading platform 4, and the loading platform 4 can be extended and retracted.

[0043] Furthermore, if Figure 3 As shown, the driving mechanism 5 also includes a connecting member 53, which is used to cooperate with a wrench and to rotate the lead screw 51. In this embodiment, the connecting member 53 is provided to facilitate cooperation with a tool such as a wrench, and the connecting member 53 is rotated by a tool such as a wrench, and the connecting member 53 is also connected to the lead screw 51, so that the connecting member 53 can drive the lead screw 51 to rotate, thereby driving the slider 52 to move along the first direction, thereby driving the loading platform 4 to move along the first direction. In other embodiments, the driving mechanism 5 also includes a handle, which is connected to the lead screw 51 and is used to manually rotate the lead screw 51; or, the driving mechanism 5 also includes a motor, which drives the lead screw 51 to rotate.

[0044] Alternatively, if Figure 1As shown, the lifting mechanism 3 is a scissor arm mechanism. Specifically, in this embodiment, the scissor arm mechanism includes two groups of scissor arm assemblies 31, a driving member 32, and an electric control box 33. The driving member 32 and the electric control box 33 are electrically connected and are both installed on the trolley 1. The electric control box 33 moves with the trolley 1, so that the driving member 32 can be controlled to work anytime and anywhere. The scissor arm assembly 31 includes a first arm frame 311 and a second arm frame 312. The first arm frame 311 and the second arm frame 312 are hinged to each other. The two ends of the first arm frame 311 are respectively hinged to the trolley 1 and the lifting platform 2, and the two ends of the second arm frame 312 are respectively slidably connected to the trolley 1 and the lifting platform 2. The two groups of scissor arm assemblies 31 and the driving member 32 are also hinged. The scissor arm assembly 31 is driven by the driving member 32 to extend and retract up and down in the vertical direction, thereby driving the lifting platform 2 to lift and lower in the vertical direction. In other embodiments, the lifting mechanism 3 may also be a guide rail mechanism or a winch mechanism, and both the guide rail mechanism and the winch mechanism can lift the lifting platform 2 along the vertical direction.

[0045] In this embodiment, the driving member 32 is an electric thrust cylinder, and there are two groups of driving members 32. The two groups of driving members 32 work together to drive the scissor arm assembly 31 to rise and fall while also providing better stability. In other embodiments, the driving member 32 may also be a hydraulic push rod.

[0046] Alternatively, if Figure 1 and Figure 4 As shown, the telescopic lifting vehicle also includes a limiter 8, which is installed on the trolley 1. When the lifting mechanism 3 drives the lifting platform 2 to rise in the vertical direction, the limiter 8 is used to limit the lifting platform 2 from descending in the vertical direction. Specifically, in this embodiment, the device also includes a limiter 8, which includes a limiter seat 81 and a limiter pad 82, and a plurality of limiters 82 are provided. After the lifting mechanism 3 rises to a certain height and stops rising, the upper end of the limiter seat 81 abuts on the crossbeam of the lifting mechanism 3 to support the crossbeam, and the lower end of the limiter seat 81 abuts on the limiter pad 82, and the limiter pad 82 abuts on the base 11 of the trolley 1. The number of limiters 82 used is determined according to the use of the lifting mechanism 3. Since the lifting mechanism 3 is driven by electricity, when the power supply is suddenly lost, the lifting platform 2, the driving mechanism 5, the loading platform 4 and the object suspended in the air will inevitably press the lifting mechanism 3 down in the vertical direction under the action of gravity. Therefore, at least one set of limiting members 8 is required to mechanically limit the lifting mechanism 3 after the lifting, so as to ensure that the lifting mechanism 3 will not retract automatically in the event of a power outage. The limiting members 8 can directly abut against the lifting platform 2, or can abut against the scissor arm assembly 31, so as to limit the downward movement range of the lifting platform 2.

[0047] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
