Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0028] like Figure 1 to Figure 2 As shown in the figure, in the embodiment of the utility model, a telescopic movable lithium battery hoist comprises a chassis 1, a column vertically fixed on the chassis 1, a hydraulic lifting module and a battery power supply module 3 are arranged on one side of the column,

[0029] The column comprises a first column portion 41 vertically fixed on the chassis 1 and a second column portion 42 located on the top of the first column portion 41. The second column portion 42 is coaxially arranged with the first column portion 41 and the ends of the two columns form a sliding fit.

[0030] A lifting rod is vertically arranged in the center of the first column 41, and the lifting rod is lifted and lowered under the drive of the hydraulic lifting module. A mounting seat 6 is transversely passed through and fixed to the second column 42, and a fork frame 8 is transversely connected to the mounting seat 6. A driving mechanism 61 is fixed inside the mounting seat 6, and the output end of the driving mechanism 61 is connected to one end of the fork frame 8.

[0031] A pulley chain assembly for controlling the lifting and lowering movement of the mounting seat 6 is provided at the top of the lifting rod, and the battery power supply module 3 supplies power to the hydraulic lifting module and the driving mechanism 61 .

[0032] Through this setting, the battery power supply system supplies single-phase AC power, changes the voltage through the frequency converter and transmits power to the hydraulic lifting module, drives the telescopic rod to rise, and drives the pulley chain assembly to move upward, so that the mounting seat and the drive mechanism can move upward; when reaching a certain height, the battery power supply module transmits power to the drive mechanism, flips the fork arm, and realizes flipping and unloading, thus solving the problem of traditional hoists requiring fixed-point operation, and using battery power to achieve sustainable material transfer at different work locations. At the same time, the telescopic column has a more compact structure and can be used to enter height-restricted areas.

[0033] The lifting rod comprises a fixed sleeve portion 21 fixed to the bottom of the first column portion 41 and a telescopic rod portion 22 arranged vertically and one end of which is lifted and lowered in the fixed sleeve portion 21.

[0034] The pulley chain assembly includes a pulley 51 hinged to the top of the telescopic rod portion 22, and a chain 52 sleeved on the pulley 51, the chain 52 has a first fixed end fixedly connected to the fixed sleeve portion 21, and a second fixed end fixedly connected to a side of the mounting seat 6 located inside the second column portion 42.

[0035] With this arrangement, the pulley is lifted using the lifting rod. Since the first fixed end of the chain cannot move, the second fixed end of the chain will automatically rise, thereby causing the mounting base and the fork frame to rise synchronously to complete the lifting operation.

[0036] A position adjustment block 211 is sleeved on the outer periphery of the fixed sleeve portion 21, and the first fixed end of the chain 52 is detachably connected to the fixed sleeve portion 21. The position adjustment block 211 slides vertically on the fixed sleeve portion 21. The inner wall of the first column portion 41 is also connected to a first limit block 411 which is located above the position adjustment block 211 and has an adjustable height. The first limit block 411 limits the upward movement of the position adjustment block 211.

[0037] Through this arrangement, the first fixed end of the chain and the fixed sleeve portion can be detachably connected, which is convenient for the inspection and replacement of the chain. At the same time, through the arrangement of the position adjustment block and the first limit block, the position of the first fixed end can be adjusted according to the actual length of the chain, further improving the applicability and flexibility of the device.

[0038] The column wall of the first column portion 41 is further connected with a second limit block 412 which is located below the position adjustment block 211 and has an adjustable height. The second limit block 412 limits the position adjustment block 211 from moving downward.

[0039] Through this arrangement, the second limiting block cooperates with the first limiting block to limit the upper and lower ends of the position adjustment block, further improving the stability of the connection.

[0040] The side wall of the first column portion 41 is provided with a sliding groove along the vertical sliding position of the position adjustment block 211 , and the first limiting block 411 and the second limiting block 412 are fixed to the first column portion 41 by screws passing through the sliding groove.

[0041] Through this arrangement, the sliding groove limits the first and second limit blocks to move only vertically, and the limit blocks are fixed to the sliding groove of the first column portion by screws, so that the limit blocks can be adjusted in height while ensuring the stability of the limit blocks connected to the first column portion.

[0042] The side surface of the position adjustment block 211 close to the first and second limit blocks forms an upper abutting inclined surface 2111 and a lower abutting inclined surface 2112 with the upper end surface and the lower end surface thereof, respectively.

[0043] The first limiting block 411 has a first abutting inclined surface 4111 abutting against the upper abutting inclined surface 2111 and a first abutting plane 4112 abutting against the upper end surface of the position adjustment block 211.

[0044] The second limiting block 412 has a second abutting inclined surface 4121 abutting against the lower abutting inclined surface 2112 and a second abutting plane 4122 abutting against the lower end surface of the position adjustment block 211 .

[0045] Through this arrangement, the limiting effect of the first limit block and the second limit block on the position of the position adjustment block is improved, the upper abutment slope, the upper abutment slope, the first abutment slope and the second abutment slope effectively reduce the wear problem between the position adjustment block and the first and second limit blocks, and the service life and safety of the structure are improved. The first and second abutment planes further improve their locking effect on the position of the position adjustment block.

[0046] The driving mechanism 61 is a rotary motor. Through this arrangement, the rotation and tilting of the fork frame can be achieved.

[0047] The hydraulic lifting module includes an oil pump motor 71 and an oil cylinder 72 . The output end of the oil pump motor 71 is connected to the oil cylinder 72 , and the oil cylinder 72 is connected to the lifting rod.

[0048] Through this setting, the frequency converter changes the voltage to transmit electricity to the hydraulic lifting module, and the oil pump motor is started to drive the hydraulic pump to deliver hydraulic oil to the cylinder, thereby achieving the lifting of the telescopic rod.

[0049] The fork frame 8 is connected to a barrel 9, and the barrel opening of the barrel 9 is connected to an electric butterfly valve 91. Through this arrangement, the electric butterfly valve controls the opening and closing of the barrel opening to ensure that the barrel is not easy to leak.

[0050] The chassis 1 is a wheeled chassis. Through this arrangement, the device can be further conveniently moved to a desired area.

[0051] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
