The telescopic sleeve and I-beam are moved to the middle of the boom, increasing the distance between the module plate and the I-beam, that is, extending the support position of the two support points to improve the support effect.

[0021] 3. The present invention utilizes the first pull rope to share the tension exerted on the tension rope, and the second pull rope transmits the tension to the second manual hydraulic pump, so that the hydraulic oil in the second manual hydraulic pump enters the second hydraulic telescopic rod, thereby increasing the clamping force of the pre-tightening clamp on the positioning block and improving the pre-tightening force. The greater the bearing capacity of the boom, the greater the tension exerted on the tension rope and the first pull rope, thereby increasing the pre-tightening force and improving the bearing capacity of the modular structure.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0037] Example 1

[0038] This embodiment provides a modular lifting device that can be assembled quickly, such as Figure 1 and Figure 2 As shown, it includes a crane frame 1, the top of the crane frame 1 is rotatably connected to a boom 5, the top of the crane frame 1 is provided with a module connection mechanism 3, the module connection mechanism 3 includes a module plate 31, a limiting counterweight 2 is placed on the top of the crane frame 1, and a support rod 4 supported on the crane frame 1 is installed at a height on the side of the module plate 31, and the bottom of the crane frame 1 is rotatably connected to a crawler.

[0039] like Figure 2 and Figure 3 As shown, a module plug-in 32 for plugging in the boom 5 is fixedly installed on the side of the module plate 31, and a positioning block 33 is slidably connected inside the module plug-in 32. A return spring is elastically connected between the side of the positioning block 33 and the module plug-in 32. The positioning block 33 adopts a wedge-shaped structure. When the boom 5 is installed, a slot for accommodating the positioning block 33 is opened inside the boom 5, and the position of the boom 5 is fixed by inserting the positioning block 33 into the slot.

[0040] like Figure 5 and Figure 6As shown, the internal sliding connection of the boom 5 is provided with a clamping wedge 34, and the side of the clamping wedge 34 is fixedly installed with a pre-tightening clamp 36 that hinders the sliding of the positioning block 33. The internal sliding connection of the boom 5 is provided with a gravity guide block 35 that squeezes the clamping wedge 34. The pre-tightening clamp 36 adopts an L-shaped structure. The pre-tightening clamp 36 is inserted between the positioning block 33 and the module plug-in 32. The end of the pre-tightening clamp 36 adopts an inclined block structure. The side of the positioning block 33 away from the boom 5 adopts a chamfered structure. The inclined surface of the pre-tightening clamp (36) has the same inclination angle as the chamfered inclined surface of the positioning block 33.

[0041] Under the action of gravity, the gravity guide block 35 squeezes the clamping wedge block 34, and the clamping wedge block 34 and the pre-tightening clamp block 36 slide toward the direction of the positioning block 33. The pre-tightening clamp block 36 is used to squeeze the positioning block 33 and squeeze the positioning block 33 out of the module plug-in 32, so that the positioning block 33 is clamped with the boom 5, and at the same time, the position of the positioning block 33 is clamped and restricted to prevent the positioning block 33 from retreating into the module plug-in 32.

[0042] like Figure 7 As shown, a sliding groove is provided on the side of the clamping wedge 34, and an embedded wheel 37 is fixedly installed on the side of the gravity guide block 35 facing the clamping wedge 34. The embedded wheel 37 extends into the sliding groove of the clamping wedge 34. The gravity guide block 35 uses the embedded wheel 37 to squeeze the clamping wedge 34. At the same time, when the gravity guide block 35 slides away from the clamping wedge 34, the gravity guide block 35 uses the embedded wheel 37 to reset the clamping wedge 34.

[0043] When the boom 5 is in use, the height of one end of the boom 5 connected to the module plate 31 is lower than that of the other end. At this time, the height of the gravity guide block 35 is higher than that of the clamping wedge 34. Under the action of gravity, the gravity guide block 35 squeezes the clamping wedge 34 so that the pre-tightening block 36 clamps and limits the position of the positioning block 33.

[0044] When disassembling and replacing, the boom 5 needs to be laid down to replace the boom 5. At this time, the end of the boom 5 connected to the module plate 31 is higher than the other end. The gravity guide block 35 slides in the direction away from the clamping wedge 34. The gravity guide block 35 uses the embedded wheel 37 to reset the clamping wedge 34. At this time, the pre-tightening clamp 36 releases the restriction on the positioning block 33.

[0045] In this embodiment, when the boom 5 is in use, the end of the boom 5 connected to the module plate 31 is lower than the height of the other end. Under the action of gravity, the gravity guide block 35 squeezes the clamping wedge 34, so that the pre-tightening block 36 clamps and restricts the position of the positioning block 33; when disassembling and replacing, the end of the boom 5 connected to the module plate 31 is higher than the height of the other end, and the gravity guide block 35 slides away from the clamping wedge 34, and the pre-tightening block 36 releases the restriction on the positioning block 33. The different inclination directions of the boom 5 in the operation and replacement states make the movement direction of the gravity guide block 35 under the action of gravity different, so as to distinguish the two states of operation and replacement, thereby improving replacement efficiency.

[0046] Example 2

[0047] Based on Example 1, this embodiment proposes a modular lifting equipment that can be quickly assembled, such as Figure 3 and Figure 9 As shown, an auxiliary support mechanism 6 is provided between the end of the boom 5 and the module plate 31. The auxiliary support mechanism 6 includes a tension rope 61. The two ends of the tension rope 61 are fixedly connected to the boom 5 and the module plate 31 respectively. The top of the boom 5 is fixedly installed with a connecting rope 62 that slides inside the module plate 31. The module plate 31 is internally rotatably connected to a reeling shaft 63 for reeling in the connecting rope 62. A telescopic sleeve 69 is fixedly installed inside the boom 5. The reeling shaft 63 and the telescopic sleeve 69 are connected by a transmission member. The tension rope 61, the boom 5 and the module plate 31 form a triangular structure.

[0048] The tension cable 61 increases the load-bearing capacity of the boom 5. The tension cable 61 is subjected to force, and the connecting rope 62 slides with the module plate 31. During normal operation, the angle between the module plate 31 and the boom 5 is fixed. After the boom 5 bends, the connecting rope 62 will be displaced. The displacement of the connecting rope 62 is used to rotate the winding shaft 63. The connecting rope 62 located between the boom 5 and the module plate 31 is parallel to the tension cable 61.

[0049] like Figure 9 As shown, the transmission part includes a toothed disc 64, and the winding shaft 63 is coaxially connected to the toothed disc 64. The bottom of the toothed disc 64 is meshed with a gear 65, and the bottom of the gear 65 is meshed with a toothed plate 66. The diameter of the gear 65 is smaller than the diameter of the winding shaft 63, and the diameter of the winding shaft 63 is smaller than the diameter of the toothed disc 64. When the diameter ratio is used to make a small displacement of the connecting rope 62, the displacement distance of the toothed plate 66 is correspondingly increased.

[0050] A first manual hydraulic pump 67 is fixedly mounted on the end of the toothed plate 66 . The end of the first manual hydraulic pump 67 is connected to a first hydraulic telescopic rod 68 via a hydraulic pipe. The telescopic sleeve 69 is located on the extension line of the end of the first hydraulic telescopic rod 68 .

[0051] After the gear 65 bends, the reel 63 rotates, and the reel 63 uses the gear disc 64 and the gear 65 to move the tooth plate 66. The tooth plate 66 squeezes the first manual hydraulic pump 67 to extend the first hydraulic telescopic rod 68. The first hydraulic telescopic rod 68 is inserted into the telescopic sleeve 69 and extended.

[0052] An I-steel structure is fixedly installed at the end of the telescopic sleeve 69 , and both sides of the telescopic sleeve 69 are against the inner wall of the boom 5 . The first hydraulic telescopic rod 68 is extended to make the telescopic sleeve 69 slide toward the middle of the boom 5 .

[0053] In this embodiment, after the boom 5 bends, the connecting rope 62 is displaced. The connecting rope 62 uses the winding shaft 63 and the transmission part to make the tooth plate 66 squeeze the first manual hydraulic pump 67. The first hydraulic telescopic rod 68 is inserted into the telescopic sleeve 69 and extended. The telescopic sleeve 69 and the I-beam are used to provide emergency temporary support for the boom 5 to prevent the boom 5 from further bending and causing danger. The telescopic sleeve 69 and the I-beam are moved to the middle of the boom 5, increasing the distance between the module plate 31 and the I-beam, that is, extending the support position of the two support points to improve the support effect.

[0054] Example 3

[0055] Based on the above embodiment 1 or 2, this embodiment proposes a modular lifting equipment that can be quickly assembled, such as Figure 4 and 8 As shown, an auxiliary load-bearing mechanism 7 is arranged between the clamping wedge block 34 and the pre-tightening clamp block 36. The auxiliary load-bearing mechanism 7 includes a first pull rope 71. The end of the first pull rope 71 is fixedly connected to the middle part of the tension rope 61. A second manual hydraulic pump 74 is fixedly installed on the outer wall of the boom 5. A second pull rope 72 is fixedly installed on the end of the second manual hydraulic pump 74. The first pull rope 71 and the second pull rope 72 are hooked with each other. The end of the second manual hydraulic pump 74 is connected to a second hydraulic telescopic rod 75 through a hydraulic pipe. The second hydraulic telescopic rod 75 is fixedly installed between the clamping wedge block 34 and the pre-tightening clamp block 36.

[0056] The tension rope 61 connects the module plate 31 and the boom 5. The tension rope 61 is subjected to tension. At this time, the first pull rope 71 and the second pull rope 72 are used to share the tension on the tension rope 61 to improve the bearing capacity of the boom 5. The first pull rope 71 is used to share the tension on the tension rope 61, and the second pull rope 72 transmits the tension to the second manual hydraulic pump 74, so that the hydraulic oil in the second manual hydraulic pump 74 enters the second hydraulic telescopic rod 75, thereby increasing the clamping force of the pre-tightening block 36 on the positioning block 33 and improving the pre-tightening force.

[0057] A protective shell is fixedly mounted on the outer wall of the boom 5, and a plurality of guide wheels 73 are rotatably connected inside the protective shell, and the second pull rope 72 rolls along the guide wheels 73. The guide wheels 73 reverse the direction of the second pull rope 72 so that the tension on the second manual hydraulic pump 74 is always along its axial direction.

[0058] In this embodiment, the first pull rope 71 is used to share the tension on the tension rope 61, and the second pull rope 72 transmits the tension to the second manual hydraulic pump 74, so that the hydraulic oil in the second manual hydraulic pump 74 enters the second hydraulic telescopic rod 75, thereby increasing the clamping force of the pre-tightening clamp 36 on the positioning block 33 and improving the pre-tightening force. The greater the bearing capacity of the boom 5, the greater the tension on the tension rope 61 and the first pull rope 71, thereby increasing the pre-tightening force and improving the bearing capacity of the modular structure.

[0059] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
