Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to an inner climbing tower crane supporting device and a climbing method. Background Art

[0002] Internal climbing tower cranes are widely used in the construction of super-high-rise buildings. They are anchored to the building via three climbing support beams: upper, middle, and lower. They rise as the building is constructed. To ascend, the crane must first be balanced. Then, it rests on the upper and middle climbing support beams. A hydraulic jack system lifts the crane, freeing it from the lower climbing support beam. Once the crane base reaches the height of the middle climbing support beam, it is secured to the upper and middle climbing support beams, completing one ascent. For the next ascent, the lower climbing support beam is flipped over and installed above the crane to serve as the new upper climbing support beam. The crane then continues climbing according to the same process, repeating this cycle to achieve continuous ascent. The obvious drawback of this method is the constant turnover of the climbing support beams, resulting in lengthy climbing cycles and impacting construction schedules. At the same time, the internal climbing tower crane is generally arranged inside the core tube, where the space is small. The climbing support beam needs to climb over the two support beams above, which makes the construction difficult and the safety risk high. Summary of the Invention

[0040] The present invention provides an inner climbing tower crane support device, such as Figure 1-Figure 3 As shown, it includes a support 1, a support frame 2, a climbing guide rail 3, a lifting beam 4 and a first driving member 5. The support 1 is arranged in at least three layers along the vertical direction, and each layer includes four supports 1. The four supports 1 are arranged at intervals and fixed on the main structure 100 of the building; there are at least two support frames 2, and at least two support frames 2 are respectively fixed on the four supports 1 on different layers, and the tower crane tower 200 is fixed on at least two support frames 2; there are four climbing guide rails 3, and the four climbing guide rails 3 are arranged and fixed on the support 1 corresponding to the four supports 1 on each layer, and the long axis of the climbing guide rail 3 is arranged in the vertical direction and is respectively connected to the multiple supports 1 on different layers; there are There is a supporting hole 31, and there are multiple supporting holes 31, and the multiple supporting holes 31 are arranged at intervals along the long axis direction of the climbing guide rail 3; the two ends of the support frame 2 are plugged and fixed between the supporting holes 31 of the climbing guide rail 3; there are two lifting beams 4, and the two ends of the two lifting beams 4 are respectively supported in the supporting holes 31 of the two climbing guide rails 3; the first driving member 5 is fixed on the lifting beam 4, and the output end of the first driving member 5 is vertically upward and connected to the support frame 2 below. The first driving member 5 is configured to drive the relative movement between the support frame 2 and the lifting beam 4.

[0041] like Figure 1-Figure 3As shown, in this embodiment, three layers of supports 1, namely, the upper, middle, and lower layers, are used as an example. Four supports 1 are provided on each layer, and two support frames 2 are provided. The ends of the lower support frame 2 are fixed to the four supports 1 on the lower layer, and the ends of the upper support frame 2 are fixed to the four supports 1 on the middle layer. Four climbing guide rails 3 are provided, and each climbing guide rail 3 is fixed vertically to three supports 1 in the same column (including the upper, middle, and lower layers). Among them, the support 1 and the main structure 100 of the building are pre-buried fixed connections, the support 1 and the support frame 2 are detachable connections, and the support 1 and the climbing guide rail 3 are detachable connections. When the climbing guide rail 3 is fixed, the support frame 2 and the support 1 are disassembled, and the first driving member 5 can drive the support frame 2 to rise the first stroke and then drive the tower crane tower body 200 to rise the first stroke. After the support frame 2 rises the first stroke, it can be fixed in the supporting hole 31 at the corresponding position, and reversely drive the first driving member 5 and the jacking beam 4 to rise the first stroke, and fix the jacking beam 4 in the supporting hole 31 at the corresponding position, so as to realize multiple rising strokes of the support frame 2 until the tower crane tower body 200 reaches the specified climbing height. The two ends of the upper support frame 2 are fixed on the four supports 1 on the upper layer, and the two ends of the lower support frame 2 are fixed on the four supports 1 on the middle layer, so as to realize eight-point support of the tower crane tower body 200 when working, so as to transfer the load of the tower crane tower body 200 to the main structure 100 of the building. It can be understood that the supporting device of an internal climbing tower crane of the present invention is provided with a support 1 on the main structure 100 of the building and connected to a fixed support frame 2 and a climbing guide rail 3 respectively. The tower crane body 200 is fixed on the support frame 2, which facilitates the climbing of the support frame 2 relative to the climbing guide rail 3, and realizes the climbing of the tower crane body 200 without the need for flipping the support beam, thereby achieving stable support and rapid climbing of the internal climbing tower crane, greatly shortening the climbing cycle; the connection limit of the climbing guide rail 3 to the support frame 2 enables the tower crane body 200 to climb without balancing, and multiple strokes are accumulated until the specified climbing height is reached, with a high safety factor. Preferably, the first driving member 5 is a hydraulic cylinder, which is convenient for realizing piston extension and retraction through automatic control, and the stroke is controllable.

[0042] Optionally, the support 1 includes an embedded part 11, a support frame fixing seat 12 and a climbing guide rail fixing seat 13, the embedded part 11 is buried in the main building structure 100, the support frame fixing seat 12 and the climbing guide rail fixing seat 13 are both fixed on the embedded part 11, and the support frame 2 and the climbing guide rail 3 are respectively fixed to the support frame fixing seat 12 and the climbing guide rail fixing seat 13.

[0043] like Figure 3The main building structure 100 is a concrete structure. One end of the embedded part 11 is embedded and secured by welding or bolting, while the other end is secured by welding or bolting to the support frame fixing seat 12 and the climbing guide rail fixing seat 13. In this embodiment, the support frame 2 and the climbing guide rail 3 need to be temporarily separated from and temporarily connected to the support 1 during the climbing process. Therefore, the sides of the support frame fixing seat 12 and the climbing guide rail fixing seat 13 for mounting the support frame 2 and the climbing guide rail 3 are provided with grooves for cooperating with the support frame 2 and the climbing guide rail 3 to achieve disassembly and assembly.

[0044] Optionally, the support frame 2 also includes a supporting steel corbel 21 and a second driving member 22, the second driving member 22 is fixed on the support frame 2, the supporting steel corbel 21 is fixed to the output end of the second driving member 22, and the second driving member 22 is configured to drive the supporting steel corbel 21 to extend in the horizontal direction to support on the support frame fixing seat 12 or retract to disengage from the support frame fixing seat 12.

[0045] like Figure 3 As shown, this embodiment selects a telescopic oil cylinder, i.e., a hydraulic oil cylinder, as the second driving member 22. The output shaft of the second driving member 22 is arranged in the horizontal direction. Two second driving members 22 are symmetrically arranged at both ends of the support frame 2. The supporting steel corbels 21 are arranged corresponding to the four support frame fixing seats 12. When the second driving member 22 drives the supporting steel corbels 21 to extend and retract in the horizontal direction, the supporting steel corbels 21 can be extended into the grooves of the support frame fixing seats 12 to be temporarily fixed on the support 1 to meet the support requirements of the tower crane tower body 200 during operation; when the tower crane tower body 200 needs to climb, the second driving member 22 can drive the supporting steel corbels 21 to retract and disengage from the support frame fixing seats 12, and the support frame 2 can climb upward along the climbing guide rail 3, thereby realizing the climbing of the tower crane tower body 200 without flipping the support beam. It is safe and reliable, and the climbing cycle is short, which is conducive to improving construction efficiency.

[0046] Optionally, the support frame 2 also includes a climbing guide wheel 23, and a plurality of climbing guide wheels 23 are provided. The plurality of climbing guide wheels 23 are rotatably connected to the two ends of the support frame 2. The climbing guide wheels 23 can roll on the inner or outer side of the climbing guide rail 3 to limit the horizontal displacement of the support frame 2.

[0047] like Figure 2 As shown, climbing guide wheels 23 are provided on the upper and lower sides of both ends of the support frame 2. The climbing guide wheels 23 can roll on the sides of the two climbing guide rails 3 facing the tower crane body 200. When the support frame 2 climbs, the climbing guide wheels 23 can limit the support frame 2 to move horizontally along its own long axis direction (i.e. Figure 1 Movement of the left and right limits. Figure 3, climbing guide wheels 23 are provided on the outer sides of the climbing guide rails 3 at both ends of the support frame 2, and the climbing guide wheels 23 can limit the support frame 2 in the horizontal direction along its own width direction (i.e. Figure 1 It can be seen that by providing a plurality of climbing guide wheels 23 between the support frame 2 and the climbing guide rail 3, the climbing guide wheels 23 can limit the position of the support frame 2 in the horizontal plane during the climbing process of the support frame 2, preventing movement, and avoiding the support frame 2 from getting stuck or tilting during the climbing process, thereby facilitating the smooth climbing of the support frame 2 along the climbing guide rail 3 and ensuring the lateral stability of the tower crane body 200 during the climbing process.

[0048] Optionally, the support frame 2 further includes a climbing support claw 24 and a third driving member 25, the third driving member 25 is fixed at both ends of the support frame 2, the climbing support claw 24 is fixed at the output end of the third driving member 25, and the third driving member 25 is configured to drive the climbing support claw 24 to extend in the horizontal direction to support in the support hole 31 of the climbing guide rail 3, or retract to disengage from the support hole 31.

[0049] like Figure 3 As shown, the working principles of the climbing support claw 24 and the third drive member 25 are the same as those of the supporting steel corbel 21 and the second drive member 22. The third drive member 25 drives the climbing support claw 24 to extend and retract toward both ends, thereby realizing temporary hooking and disconnection between the support frame 2 and the climbing guide rail 3. The climbing support claw 24 can be inserted into the supporting hole 31 of the climbing guide rail 3 to realize temporary hooking, which facilitates the alternating rise between the support frame 2 and the climbing guide rail 3. It should be noted that the climbing support claw 24 and the supporting steel corbel 21 are symmetrically arranged at both ends of the support frame 2 so that the force is evenly distributed. The third drive member 25 is preferably a hydraulic cylinder, which is convenient for realizing piston extension and retraction through automatic control, and the stroke is controllable.

[0050] Optionally, the hole spacing of the support holes 31 on the climbing guide rail 3 is matched with the working stroke of the first driving member 5 .

[0051] It can be understood that in the present invention, the tower crane body 200 achieves the target climbing distance by accumulating multiple strokes. In each climbing stroke, it includes temporary support and separation between the support frame 2 and the support 1, as well as temporary support and separation between the support frame 2 and the climbing guide rail 3. Therefore, when the first driving member 5 drives the support frame 2 to rise, it is necessary to ensure that the two ends of the support frame 2 can be connected to the corresponding position support holes 31 on the climbing guide rail 3. Therefore, the support holes 31 on the climbing guide rail 3 are matched with the stroke of the first driving member 5, which is conducive to the support frame 2 being able to quickly and temporarily connect with the climbing guide rail 3 in each stroke to improve the climbing efficiency.

[0052] It should be noted that the above-mentioned internal climbing tower crane support device provided by the present invention can realize automatic climbing of the tower crane tower body 200 by connecting the first driving member 5, the second driving member 22 and the third driving member 25 to the control end, so that the climbing construction is safer and the climbing efficiency is high.

[0053] The present invention also provides a climbing method for an inner climbing tower crane. According to the inner climbing tower crane support device provided above, the climbing method for the inner climbing tower crane comprises the following steps:

[0054] S1, the ends of the lifting beam 4 are inserted into the supporting holes 31 of the climbing guide rail 3 to be fixed, and the first driving member 5 drives the lower support frame 2 to move upward to the space between the support frame 2 and the support 1 to unload, and at the same time unload from the climbing guide rail 3; the support frame 2 is separated from the support 1 and the climbing guide rail 3;

[0055] like Figure 1-Figure 3 This is the support situation when the tower crane body 200 is in working condition. The two support frames 2 are supported on the lower and middle supports 1 respectively, and the upper support 1 is set at the next climbing height of the tower crane body 200. The two ends of the climbing guide rail 3 protrude from the lower support 1 and the upper support 1 to facilitate the climbing of the support frame 2. When the tower crane body 200 needs to climb, since the load of the tower crane body 200 is supported on the support 1 through the support frame 2, it is first necessary to lift the support frame 2 to the space between the support frame 2 and the support 1 through the first drive member 5 to unload the load. The load is carried by the first drive member 5, and the load between the support frame 2 and the climbing guide rail 3 is also unloaded. After unloading, the second drive member 22 drives the support steel bracket 21 to retract to disengage from the support frame fixing seat 12, and the third drive member 25 drives the climbing support claw 24 to retract to disengage from the support hole 31 of the climbing guide rail 3.

[0056] S2, the first driving member 5 continues to lift the support frame 2 up a stroke, and the tower crane body 200 rises accordingly;

[0057] After the preparation work of step S1 is completed, the tower crane body 200 can be climbed. In the first stage, the first driving member 5 lifts the support frame 2 below to a certain height. Figure 4 In the illustrated state, the output end of the first drive member 5 is extended to lift the support frame 2, causing the upper support frame 2 and the tower crane body 200 to rise a stroke. During the ascent, the climbing guide wheels 23 on the support frame 2 always roll in contact with the climbing guide rails 3 to limit the position, preventing horizontal sway of the support frame 2 and ensuring lateral stability of the tower crane body 200 during the ascent, achieving a stable climb.

[0058] S3, the two ends of the support frame 2 are again inserted into the supporting holes 31 of the climbing guide rail 3 and fixed; the two ends of the lifting beam 4 are separated from the supporting holes 31 of the climbing guide rail 3, and the output end of the first driving member 5 retracts to drive the lifting beam 4 to rise a stroke and then be inserted into the supporting holes 31 at both ends again to be fixed;

[0059] This step is an intermediate conversion step after a single stroke. After the support frame 2 has climbed one stroke, the first drive member 5 needs to prepare for the next stroke, so the first drive member 5 needs to be moved upward. The connection relationship between the ends of the lifting beam 4 and the support holes 31 of the climbing guide rail 3 can refer to the connection relationship between the ends of the support frame 2 and the support holes 31, or a commonly used connection method known in the art can be used. This is not specifically limited in this embodiment. The ends of the lifting beam 4 can be temporarily fixedly connected and disconnected from the support holes 31 as needed to facilitate the lifting operation of the lifting beam 4. Since the bottom end and output end of the first drive member 5 are respectively connected to the lifting beam 4 and the support frame 2 below, the relative position between the lifting beam 4 and the support frame 2 can be moved by retracting the output end of the first drive member 5 to facilitate multiple strokes of climbing. Specifically, the eight climbing support claws 24 at the ends of the two support frames 2 are all hooked on the support holes 31 of the climbing guide rail 3, so that the entire tower crane body 200 is supported on the climbing guide rail 3 through the two support frames 2. Then the two ends of the jacking beam 4 are separated from the supporting holes 31 of the climbing guide rail 3, and the first driving member 5, that is, the hydraulic cylinder, is retracted to drive the jacking beam 4 to rise a stroke. The state after the bottom end of the first driving member 5 drives the jacking beam 4 to rise a stroke is as follows: Figure 5 After the lifting beam 4 rises a stroke, both ends of the lifting beam 4 are again hooked in the supporting hole 31 of the climbing guide rail 3, ready for the next lifting stroke.

[0060] S4, repeat steps S2-S3 until both ends of the support frame 2 can be fixed on the support 1 at the climbing height, thus achieving one climb of the tower crane body 200.

[0061] like Figure 6 The figure shows the tower crane 200 climbing to a specified height. After multiple cumulative strokes, the tower crane 200 has risen a climbing distance. At this point, the upper support frame 2 is fixed to the upper support 1, and the lower support frame 2 is fixed to the middle support 1. The bottom support 1 can now be removed. The tower crane 200 is secured by eight steel brackets 21 at each end of the two support frames 2, extending into the support frame fixing bases 12 of the support 1 to meet the support requirements of the tower crane 200 during operation. At this point, the lifting beam 4 and the first drive member 5 are located below the lower support frame 2 and fixed to the climbing guide rail 3.

[0062] The climbing method of the internal climbing tower crane of the present invention drives the support frame 2 to rise relative to the climbing guide rail 3 through the first driving member 5. The climbing method is simple and easy to implement, and realizes the climbing of the tower crane tower body 200 without flipping the support beam, reducing the safety risk of the tower crane tower body 200; after multiple rising strokes, the tower crane tower body 200 reaches the specified climbing height, and no balancing is required during the climbing process, shortening the climbing period of the tower crane tower body 200.

[0063] Optionally, the climbing method of the inner climbing tower crane further includes S5, arranging a layer of supports 1 at the next climbing height position of the tower crane body 200.

[0064] like Figure 7 As shown, a layer of supports 1 is installed above the original upper supports 1 as the new upper supports 1, and the original upper and middle supports 1 serve as the new middle and lower supports 1, respectively. The distance between the new upper and middle supports 1 is equal to the next climb distance of the tower crane body 200. The installation of this layer of supports 1 can be carried out simultaneously with the work on the tower crane body 200, thus not taking up additional construction time.

[0065] Optionally, the climbing method of the inner climbing tower crane further includes S6, the climbing guide rail 3 climbs upward, the climbing distance is the next climbing height of the tower crane tower body 200, and the climbing guide rail 3 is fixed on the support 1 again.

[0066] like Figure 7 As shown, during the climbing process of the tower crane body 200, the support frame 2 climbs relative to the climbing guide rail 3. After the tower crane body 200 climbs to its proper position, the lifting beam 4 and the lower support frame 2 are fixed to the middle position of the climbing guide rail 3. This step S6 is to set the support 1 at the climbing height of the next tower crane body 200, and then lift the climbing guide rail 3 to the height fixed by the new upper, middle and lower supports 1, that is, the bottom end of the climbing guide rail 3 is connected to the new lower support 1, and then connected upward to the new middle and upper supports 1 in sequence. The specific lifting or climbing method is similar to the climbing method of the support frame 2. The difference is that the support frame 2 is fixed and the relative position of the climbing guide rail 3 relative to the support frame 2 is changed. During the reciprocating extension and retraction of the first driving member 5, the lifting beam 4 continuously changes the position of the supporting hole 31 on the climbing guide rail 3 where the lifting beam 4 and the support frame 2 are hung, and the climbing distance of the tower crane body 200 is gradually increased. Figure 8 The state shown is ready for the next climbing of the tower crane body 200. The climbing process of the climbing guide rail 3 does not affect the working process of the tower crane body 200 and can be carried out simultaneously, thereby shortening the construction period.

[0067] 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 embodiments of the present invention.
