[0029] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0030] The following is combined with Figure 1To further illustrate the present invention, a detachable indoor mobile lifting pallet truck comprises a movable base 1, which is convenient for moving the lifting pallet truck indoors, and a column 2 is detachably connected to the base 1, and a support arm 3 is fixed to the upper end of the column 2, and a lifting arm 4 is hinged on the support arm 3, and a diagonal brace 5 is hinged on the lifting arm 4, and a plurality of support plates 6 are fixed to the column 2, and a lock 7 cooperating with the support plate 6 is provided at the lower end of the diagonal brace 5, and the lock 7 and the support plate 6 cooperate to fix the diagonal brace 5 on the column 2, and an electric winch 8 is installed above the base 1, and the electric winch 8 is installed on the side of the column 2 away from the hook 11. Installing the electric winch 8 on the base 1 reduces the weight of the column 2, so that the column 2 can be more conveniently disassembled. A plurality of rotatable pulleys 9 are respectively provided on the column 2 and the boom 4. The rope 10 on the electric winch 8 is fixed to the hook 11 after passing through the plurality of pulleys 9. Specifically, the hook 11 is provided with a locking device, and the width of the base 1 is smaller than the width of the door. The detachable column 2 is convenient for separating the column 2 and the base 1, so as to facilitate the entry and exit of the hoisting pallet truck in and out of the door; further, the hinged structure of the support arm 3 and the boom 4 is convenient for folding the boom 4 under the support arm 3, and the supporting structure of the diagonal brace 5, the support plate 6 and the lock 7 is coordinated, so that the diagonal brace 5 and the lock 7 are convenient for folding between the boom 4 and the column 2 when the boom 4 is folded. The folding design makes it convenient to carry the column 2 and the boom 4 into the door. Secondly, the design of multiple support plates 6 can easily adjust the pitch angle of the boom 4, so as to adapt to more lifting scenarios. The height of the base 1 plus the column 2 is greater than the height of the door. In the present invention, after the column 2 is removed from the base 1, the arm 4 and the diagonal brace 5 are folded and accommodated on one side of the column 2, and then placed horizontally on the base 1, and pushed into or out of the door by the base 1. In this process, since the column 2 and the arm 4 are not separated from the motor winch on the base 1, it is not necessary to remove the rope 10 and the hook 11. This structural design simplifies the assembly process and improves the disassembly speed and installation speed.

[0031] An implementation method of the lock 7: Figure 2 The lock buckle 7 includes a hanging ring 071 hinged at the lower end of the diagonal brace 5, the hanging ring 071 is hung on a support plate 6, and the other support plate 6 supports the lower end of the diagonal brace 5. The support plate 6 at the hanging ring 071 is located at the support plate 6 at the diagonal brace 5. The hanging ring 071 and the diagonal brace 5 fall on the two support plates 6 from top to bottom, and the two support plates 6 jointly support the boom 4 through the diagonal brace 5, and the supporting effect is good. Secondly, the structural design is convenient for installation and disassembly.

[0032] As another embodiment of the present invention: a pin hole 061 is provided on the support plate 6, and a latch pin 072 is inserted into the pin hole 061 of the support plate 6 at the hanging ring 071, and the pin rod of the latch pin 072 limits the horizontal movement of the hanging ring 071, which is beneficial to improving the safety of the pallet trolley. Specifically, the diameter of the head of the latch pin 072 is larger than the diameter of the pin rod, which can limit the upward movement of the hanging ring 071. This structural design further improves the safety of the pallet trolley.

[0033] An implementation method of the hanging ring 071: refer to the attached Figure 5 The hanging ring 071 includes two hanging plates 0711, a hinge shaft is arranged between the two hanging plates 0711, the hanging plate 0711 is hinged to the diagonal support 5 through the hinge shaft, and a hanging rod 0712 cooperating with the support plate 6 is fixed to one end of the hanging plate 0711 away from the hinge shaft, and the diameter of the hanging rod 0712 is consistent with the diameter of the hinge shaft. Specifically, the width of the support plate 6 is smaller than the width of the column 2, and the width of the hanging ring 071 is consistent with the width of the column 2. This structural design makes the two sides of the column 2 relatively flat, which is convenient for placing the column 2 and the boom 4 on the base 1.

[0034] Furthermore, when the boom 4 and the diagonal brace 5 are folded and accommodated below the support arm 3 , the boom 4 is arranged parallel to the column 2 .

[0035] An implementation method of detachably connecting the column 2 and the base 1: the base 1 is provided with a through hole matching the column 2, and a clamping plate 12 matching the clamping slot of the column 2 is provided below the base 1. After the column 2 passes through the through hole, the upper end of the base 1 is clamped with the column 2, and the clamping plate 12 is clamped into the clamping slot to fix the column 2 on the base 1. The clamping structure above the base 1 is matched with the clamping structure below (the clamping plate 12 and the clamping slot), and the through hole restricts the column 2. This structural design has a good fixing effect on the column 2 and the base 1, and is also convenient for installation and disassembly.

[0036] An embodiment of the upper end of the base 1 and the column 2 being connected by clamping: Figure 4 , the base 1 is fixed with a limiting block 13 at the opening of the through hole, and the lower end of the column 2 is fixed with a limiting groove 14 that matches the limiting block 13, and the groove of the limiting groove 14 faces downward. Another implementation method of the upper end of the base 1 being clamped with the column 2: the limiting groove 14 is set at the opening of the through hole, and the limiting block 13 is fixed on the column 2. When the column 2 is inserted into the through hole, the limiting block 13 will also be inserted into the limiting groove 14 to complete the double clamping, and the entire loading and unloading process is simple. The card plate 12 inserted in the card slot is located below the limiting block 13, and the limiting block 13 can improve the structural strength at the through hole.

[0037] Specifically, the outer contour of the limiting block 13 is a rectangle, and the outer contour of the limiting block 13 may also be a circle.

[0038] As another embodiment of the present invention: a pull rod 15 is fixed on the card plate 12, and a spring 16 is sleeved on the pull rod 15. One end of the spring 16 is connected to the card plate 12, and the other end is connected to the base 1. The card plate 12 is slidably connected to the base 1. Pull the pull rod 15 to pull the card plate 12 out of the slot, release the restriction on the column 2, and pull the column 2 from the bottom to the top to complete the disassembly. Pull the pull rod 15 to pull the card plate 12 out from the bottom of the through hole, pass the lower end of the column 2 through the through hole, and then release the pull rod 15. The card plate 12 enters the slot under the action of the spring 16 to complete the locking of the column 2. The bottom of the base 1 is relatively narrow, and the card plate 12 is moved by the cooperation of the pull rod 15 and the spring 16 to facilitate locking and unlocking the column 2.

[0039] As another embodiment of the present invention: a vertical plate 17 is fixed to the bottom of the base 1, the pull rod 15 is slidably connected to the vertical plate 17, the spring 16 is arranged between the clamping plate 12 and the vertical plate 17, and a baffle 18 is fixed on the pull rod 15, and the baffle 18 is located at one end of the vertical plate 17 away from the clamping plate 12. When the elastic force of the spring 16 pushes the clamping plate 12 into the clamping slot, the baffle 18 is restricted by the vertical plate 17, thereby preventing the clamping plate 12 from moving further.

[0040] Specifically, a U-shaped groove is fixed at the bottom of the base 1, and the clamping plate 12 slides along the U-shaped groove.

[0041] As another embodiment of the present invention: a plurality of universal wheels are rotatably arranged at the bottom of the base 1 .

[0042] As another embodiment of the present invention: a chamfered right angle structure is provided at the lower end of the column 2, which is convenient for guiding the column 2 into the through hole, and a chamfered right angle structure is provided at the front end of the card plate 12, which is convenient for guiding the card plate 12 into the card slot.

[0043] As another embodiment of the present invention: Figure 3 There are five pulleys 9, the first pulley 9, the second pulley 9 and the third pulley 9 are respectively distributed at the lower end, the upper end and the top end of the column 2, the fourth pulley 9 is distributed at the upper side of the front end of the boom 4, and the fifth pulley 9 is distributed at the end of the front end of the boom 4. The rope 10 of the electric winch 8 passes between the first pulley 9 and the column 2, passes through the outer side of the second pulley 9, the upper side of the third pulley 9, the upper side of the fourth pulley 9 and the outer side of the fifth pulley 9, and is fixed to the hook 11. It should be noted that: in the horizontal direction, the side of the pulley 9 close to the column 2 is the inner side, and the side of the pulley 9 close to the boom 4 is the inner side.

[0044] Specifically, both ends of the column 2 are solid structures, and the middle part is a hollow structure.

[0045] The present invention has a simple structure and a detachable column 2, so that part of the column 2 can be placed horizontally on the base 1 to enter and exit the room, which is easy to use. The motor winch, the boom 4, the pulley 9 and the hook 11 cooperate to realize the hoisting function, so as to facilitate the indoor engineering hoisting work. Secondly, the hinged structure of the support arm 3 and the boom 4 makes it convenient to fold the boom 4 under the support arm 3. The supporting structure of the diagonal brace 5, the support plate 6 and the lock 7 makes it convenient to fold the diagonal brace 5 and the lock 7 between the boom 4 and the column 2 when the boom 4 is folded. Thereby, it is convenient to carry the column 2 and the boom 4 into the door. The folding design can improve the installation efficiency, reduce the installation cost and simplify the construction process. Secondly, the design of multiple support plates 6 can easily adjust the pitch angle of the boom 4, so as to adapt to more hoisting scenes.
