[0002] At present, the main climbing methods of internal climbing tower cranes are side-mounted jacking by cylinder and center-mounted jacking. The side-mounted jacking requires a larger operating space, i.e., the size of the elevator shaft, and is not easy to operate. The center-mounted jacking requires a smaller operating space, i.e., the size of the elevator shaft, and the operation is performed inside the internal climbing base section. It is easy to operate and has a wide range of applications. In the current installation form of the climbing belt of the center-mounted jacking, the spacing between the climbing claws is large, and the climbing belt length far exceeds twice the internal climbing height, resulting in a longer climbing belt length and higher raw material costs. Summary of the invention

[0006] In the embodiment of the present invention, the distance between the step-changing climbing claw and the lower end surface of the telescopic beam is L4, the distance between the step located at the top and the inner climbing frame located at the top is L5, and L5 is less than L3-(L2-L1)-L4.

[0007] In an embodiment of the present invention, the climbing system further comprises a support block mounted on the top of the inner climbing frame, wherein the support block can flip back and forth between an avoidance position and a support position, and limitably supports the climbing belt at the support position.

[0008] In an embodiment of the present invention, the support block is provided with a limiting member for limiting the position of the climbing belt and a positioning groove for the climbing belt to pass through, and the limiting member and the positioning groove are arranged in sequence along the width direction of the inner climbing frame.

[0022] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] The climbing system according to the present invention will be described below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, a climbing system 100 is provided, wherein the climbing system 100 includes an inner climbing frame 1, a climbing mechanism 2 and a climbing belt 3; the inner climbing frame 1 is arranged on a load-bearing beam fixed to a building; the climbing mechanism 2 is located inside the inner climbing frame 1, and the climbing mechanism 2 includes an inner climbing base section 21 and a lifting beam 22 arranged in sequence along the up-down direction, the lifting beam 22 is connected to the fixed beam 211 of the inner climbing base section 21 through a lifting cylinder 23, and the bottom of the inner climbing base section 21 is arranged There is a telescopic beam 213 for positioning with the inner climbing frame 1, a step-changing climbing claw 212 is provided near the bottom of the inner climbing base section 21, and a lifting climbing claw 221 is provided on the jacking beam 22; the climbing belt 3 is hoisted on the inner side of the inner climbing frame 1 and can be lifted and lowered relative to the inner climbing frame 1, and the climbing belt 3 is evenly spaced along the length direction. A plurality of steps 31 for positioning with the lifting climbing claw 221 and the step-changing climbing claw 212 are provided, and the length of the climbing belt 3 is greater than or equal to the inner climbing height of the climbing mechanism 2 and less than twice the inner climbing height. It can be understood that the inner climbing frame 1 in this embodiment can be set in the elevator shaft of the building, and can also be hung on the wall of the building.

[0025] The inner climbing frame 1 in this embodiment is a frame structure, and the climbing system 100 is mainly used in cranes. The tower crane of the crane is usually installed on the inner climbing base section 21 and climbs with the climbing mechanism 2, wherein the inner climbing height of the climbing mechanism 2 is the total inner climbing distance that the tower crane can climb. Figure 1 The structures in the middle dotted lines are the lifting climbing claw 221 and the step-changing climbing claw 212 respectively.

[0026] When the climbing system 100 in this embodiment is used for climbing operation, the jacking cylinder 23 is used to jack up the fixed beam 211, driving the inner climbing base section 21 to rise until the step-changing climbing claw 212 exceeds the step 31, the step-changing climbing claw 212 is operated to make it fall on the step 31, the jacking cylinder 23 is retracted, and the inner climbing base section 21 is supported by the climbing belt 3, and the jacking cylinder 23 is continuously retracted until the jacking climbing claw 221 located below exceeds a step 31, the jacking climbing claw 221 is operated to make it fall on the step 31 of the climbing belt 3, the jacking cylinder 23 is extended, and the inner climbing base section 21 climbs upward, and the telescopic operation of the jacking cylinder 23 is repeated in the above steps. Finally, after the telescopic beam 213 exceeds the inner climbing frame 1, the telescopic beam 213 is extended so that the telescopic beam 213 falls on the inner climbing frame 1, and the telescopic beam 213 and the inner climbing frame 1 are fixed.

[0027] In this embodiment, the inner climbing frame 1 is set on the load-bearing beam fixed to the building, and the climbing system 100 is placed in the middle. The climbing operation space required is small and easy to operate. The step-changing climbing claw 212 is placed at the bottom of the inner climbing base segment 21 close to the jacking climbing claw 221. Compared with the prior art in which the step-changing climbing claw 212 is placed on top, the distance between the step-changing climbing claw 212 and the jacking climbing claw 221 is reduced, so that the length of the climbing belt 3 that needs to cooperate with the climbing mechanism 2 during the climbing process of the climbing mechanism 2 is shortened to between one and two times the total inner climbing height of the climbing mechanism 2, thereby reducing the length of the climbing belt 3 and reducing the raw material cost of the climbing system 100.

[0028] In one embodiment, the step-changing climbing claw 212 and the lifting climbing claw 221 can rotate around the inner climbing base section 21 and the lifting crossbeam 22 respectively, the distance between the step-changing climbing claw 212 and the lifting climbing claw 221 is L1, the distance between any two steps 31 is L2, the lifting stroke of the lifting oil cylinder 23 is L3, and the rotation radius of the step-changing climbing claw 212 and the lifting climbing claw 221 are both a, L2<L3+L1+a<2*L2. In this embodiment, the length of the climbing belt 3 that needs to be coordinated with the climbing mechanism 2 is further shortened by specifically coordinating the distance between the step-changing climbing claw 212 and the lifting climbing claw 221, the distance between the two steps 31, the lifting stroke of the lifting oil cylinder 23, and the rotation radius of the step-changing climbing claw 212 and the lifting climbing claw 221, thereby shortening the height of the climbing belt 3 as much as possible.

[0029] In the embodiment of the present invention, the distance between the step-changing climbing claw 212 and the lower end surface of the telescopic beam 213 is L4, and the distance between the step 31 at the top and the inner climbing frame 1 at the top is L5, L5<L3-(L2-L1)-L4. In this embodiment, the distance between the step-changing climbing claw 212 and the jacking climbing claw 221 and the jacking stroke of the jacking cylinder 23 are matched, so that the length of the climbing belt 3 that needs to be matched with the climbing mechanism 2 is shortened to the same as the inner climbing height of the climbing mechanism 2.

[0030] like Figure 2As shown, in an embodiment of the present invention, the climbing system 100 also includes a support block 4 installed on the top of the inner climbing frame 1, and the support block 4 can be flipped back and forth between the avoidance position and the support position, and limit the support of the climbing belt 3 at the support position. In one embodiment, the support block 4 can be flipped 180 degrees relative to the inner climbing frame 1. When the climbing belt 3 falls, the support block 4 is in the avoidance position. At this time, the support block 4 faces the outside of the inner climbing frame 1. After the climbing belt 3 falls vertically to a certain position, the support block 4 is flipped so that the support block 4 limits the support of the climbing belt 3 at the support position. When the climbing belt 3 needs to rise, the support block 4 can release the limit support of the climbing belt 3, and the climbing belt 3 is lifted by the driving member and the support block 4 is flipped to the avoidance position. In this embodiment, the climbing belt 3 can be assembled and disassembled only by flipping the support block 4, so that the climbing belt 3 can be assembled and disassembled without the help of auxiliary tools, which reduces the transportation and use costs.

[0031] In one embodiment, the support block 4 is provided with a limiting member 41 for limiting the position of the climbing belt 3 and a positioning groove 42 for the climbing belt 3 to pass through, and the limiting member 41 and the positioning groove 42 are arranged in sequence along the width direction of the inner climbing frame 1. In this embodiment, the positioning groove 42 passes through the support block 4 and is open on one side. After the climbing belt 3 falls to a certain position, the support block 4 can be flipped over so that the climbing belt 3 enters the positioning groove 42 through the opening and is positioned and matched with the positioning groove 42. Then the limiting member 41 can be operated to limit the climbing belt 3. In this embodiment, the limiting pin can be passed through the limiting member and the climbing belt 3 in sequence to achieve the limiting of the climbing belt 3. In addition, in the embodiment of the present invention, the limiting member 41 located at the supporting position is located outside the positioning groove 42.

[0032] In one embodiment, a reinforcing pad 11 is provided on the inner side of the top of the inner climbing frame 1 corresponding to the supporting block 4, and the supporting block 4 located at the supporting position is supported on the reinforcing pad 11. In this embodiment, the upper plane of the reinforcing pad 11 is the supporting plane, and the inner climbing frame 1 specifically supports the supporting block 4 through the reinforcing pad 11, which can avoid the situation where the supporting block 4 is unstable and causes the climbing belt 3 to shake.

[0033] In the embodiment of the present invention, the inner climbing frame 1 is provided with a bracket 5, and the support block 4 is hinged to the bracket 5 through a support pin 6. The bracket 5 in this embodiment can be welded to the inner climbing frame 1, and the support block 4 is hinged to the inner climbing frame 1 in the form of the support pin 6 passing through the bracket 5 and the support block 4 in sequence. Figure 2 As shown, the support block 4 is in the supporting position, and the reinforcing pad 11 and the supporting pin 6 jointly support the climbing belt 3.

[0034] In one embodiment, two climbing belts 3 are hoisted on both sides of the inner climbing frame 1, and the climbing belts 3 are provided with step-changing climbing claws 212 and lifting climbing claws 221 on both sides of the inner climbing base section 21 and both sides of the telescopic beam 213, respectively. Figure 1As shown, the two climbing belts 3 are respectively arranged on the left and right sides of the inner climbing frame 1, and the step-changing climbing claws 212 and the jacking climbing claws 221 are also grouped in two, respectively cooperating with the two climbing belts 3 for positioning and supporting.
