Description

Technical Field

[0001] The present application relates to the technical field of tower crane equipment, and in particular to a pedestrian passage between a climbing frame and a tower crane. Background Art

[0002] Tower cranes are commonly used lifting equipment in construction projects. In house construction, as the floors continue to rise, the tower cranes also need to increase the standard sections of the tower cranes accordingly. The cab of the tower crane is generally located at the top of the tower crane, and the cab will rise as the tower crane rises. However, there are many inconveniences and safety hazards in the process of the tower crane driver entering the cab from the ground. Usually, there are two ways for the tower crane driver to enter the cab. One is to climb up one section at a time along the ladder on the standard section from the bottom of the tower crane; this method is still feasible for tower cranes with lower heights, but for tower cranes with higher heights, it is a huge test of the physical strength of the tower crane driver, and there are huge risks in the climbing process. The second is to take the construction elevator to the corresponding construction floor, and then set up a simple pedestrian walkway between the corresponding floor and the standard section of the tower crane. This not only requires the construction of pedestrian walkways at high altitude, which is difficult to construct, but also requires the demolition and construction of pedestrian walkways corresponding to different floors as the floors and tower cranes continue to rise, and the construction work is cumbersome.

[0028] Example

[0029] This embodiment provides a pedestrian passage between a climbing frame 1 and a tower crane, which includes a passage assembly and a flip pedal 12. Specifically, the climbing frame 1 is installed on the main building, and as the construction floor rises, the climbing frame 1 can climb to a corresponding height, and the tower crane also increases the standard section 2 to increase the height.

[0030] Reference Figure 1 and Figure 2 As shown, since the pedestrian passage is actually a passage between the floor and the standard section 2, only the standard section 2 is shown in the figure instead of the complete structure of the tower crane. The passage assembly includes support rods 8, walkway plates 7, steel wire ropes and moment braces 11.

[0031] There are two support rods 8, one end of each of the two support rods 8 is connected to the climbing frame 1, and the other end extends in the direction of the tower crane. Specifically, a cross buckle can be used to connect the support rod 8 to the vertical rod 18 on the climbing frame 1. The walkway plate 7 is installed on the support rod 8, and specifically, the walkway plate 7 can be fixed to the support rod 8 by M16 bolts, and the walkway plate 7 extends along the extension direction of the support rod 8.

[0032] One end of the steel wire rope is connected to the climbing frame 1 and is located above the support rod 8, and the other end is connected to the support rod 8, so that the climbing frame 1, the steel wire rope and the support rod 8 form a triangular stable structure, and the climbing frame 1 bears the gravity of the channel assembly.

[0033] One end of the moment-resistant brace 11 is connected to the climbing frame 1 and is located below the support rod 8, and the other end is connected to the support rod 8, so that the climbing frame 1, the moment-resistant brace 11 and the support rod 8 form a triangular stable structure, thereby increasing the moment-resistant capacity of the channel assembly. When the climbing frame 1 climbs to a corresponding height as the floor increases, the channel assembly moves to the corresponding height accordingly. The connection stability between the channel assembly and the climbing frame 1 is improved by the steel wire rope and the moment-resistant brace 11, thereby ensuring the safety and stability of the channel assembly during movement.

[0034] The flip pedal 12 is hinged to the end of the walkway board 7 away from the climbing frame 1, so that the flip pedal 12 is overlapped with the standard part of the tower crane after being rotated forward, and the flip pedal 12 is folded on the walkway board 7 after being rotated reversely. When the tower crane driver needs to pass through the pedestrian passage, the flip pedal 12 is rotated forward to overlap with the standard part. When the standard part needs to be added to increase the height of the tower crane, the flip pedal 12 is rotated reversely to avoid interference with the tower crane.

[0035] In this embodiment, the support rod 8, the moment-resisting support rod 11, etc. can all be made of steel pipes with a diameter of 48 mm. The walkway plate 7 can be made of a steel plate with a thickness of 3 mm, and the steel wire rope can be made of a steel wire rope with a diameter of 21.5 mm.

[0036] The pedestrian passage between the climbing frame 1 and the tower crane provided in this embodiment is installed on the climbing frame 1 outside the main building, so that the pedestrian passage rises with the climbing frame 1; the pedestrian passage and the tower crane are connected and disconnected by flipping the pedal 12, which is convenient for the tower crane driver to pass when connected, and avoids the pedestrian passage from interfering with the tower crane's operation of increasing the standard section 2 when disconnected. In addition, the pedestrian passage is stably installed on the climbing frame 1 through steel wire ropes and bending moment braces 11, and can be stably raised with the climbing frame 1; its structure and material selection are simple, and it can be made of materials on site at the construction site as needed, without the need for prefabrication in the factory, thereby reducing costs and improving construction efficiency.

[0037] Specifically, a cross bar 9 is connected below the support rod 8, and the cross bar 9 can be made of a steel pipe with a diameter of 48 mm. Both ends of the cross bar 9 are respectively connected to the support rod 8, and multiple cross bars 9 are arranged along the extension direction of the support rod 8. By setting the cross bar 9, on the one hand, the stability of the overall structure can be increased, and on the other hand, a binding point can be provided for the steel wire rope and an installation point can be provided for the bending moment brace 11.

[0038] Specifically, the steel wire rope includes a first steel wire rope 4 and a second steel wire rope 3, one end of the first steel wire rope 4 is connected to the cross bar 9 in the middle of the walkway board 7; one end of the second steel wire rope 3 is connected to the end of the walkway board 7 away from the climbing frame 1. The two steel wire ropes are used to tie the support rod 8 and the walkway board 7 respectively, so as to further improve the stability of the overall structure.

[0039] Specifically, one end of the anti-bending moment brace 11 is connected to the cross bar 9 at the middle position of the walkway plate 7 through a rotating buckle. The cross bar 9 provides an installation point for the anti-bending moment brace 11.

[0040] Specifically, the middle position of the moment-resisting brace 11 is connected with an oblique brace 10, and one end of the oblique brace 10 away from the moment-resisting brace 11 is connected to the climbing frame 1, so as to further enhance the moment-resisting capacity of the channel assembly.

[0041] Specifically, the two sides of the walkway plate 7 are respectively connected with the first guardrail 5; the two sides of the flip pedal 12 are respectively connected with the second guardrail 6. By providing the first guardrail 5 and the second guardrail 6, the tower crane driver is prevented from falling from the side when passing through the pedestrian passage, thereby improving safety.

[0042] Specifically, a partial blank area is provided at one end of the walkway board 7 away from the climbing frame 1, and the first guardrail 5 is not provided in the blank area; an iron chain is connected between the first guardrail 5 and the second guardrail 6. Although the iron chain is not shown in the figure, the connection method between the iron chain and the guardrail is a conventional technical means in this field. By providing a blank area without the first guardrail 5 to provide a flipping space for the flip pedal 12, and connecting the first guardrail 5 and the second guardrail 6 by an iron chain, on the one hand, it can provide anti-fall protection for the blank area, and on the other hand, by pulling the iron chain, the flip pedal 12 can be reversed to achieve the retraction of the flip pedal 12.

[0043] Specifically, the climbing frame 1 includes at least two vertical poles 18 arranged along the extension direction of the support rod 8, and the support rod 8 is sequentially connected to the two vertical poles 18. The support rod 8 is also connected to a fixing rod 13, which is located at the intersection of the support rod 8 and the vertical pole 18, and the two ends of one fixing rod 13 are respectively connected to the two support rods 8. Specifically, the climbing frame 1 is provided with at least four vertical poles 18, and each support rod 8 corresponds to and is connected to two vertical poles 18.

[0044] Specifically, refer to Figure 3 As shown, the flip pedal 12 is hinged to the walkway board 7 via a hinge 14 .

[0045] Specifically, refer to Figure 4 As shown, the protective door assembly is also included, and the protective door assembly includes a door frame 15, a door panel 16 and a lock 17. The door frame 15 is installed on the climbing frame 1; the door panel 16 is movably installed on the door frame 15, and is used to close the pedestrian passage when closed; the lock 17 is installed between the door frame 15 and the door panel 16, and is used to lock the door panel 16.

[0046] Construction process: After installing the climbing frame 1 on the main body of the building, install the channel assembly on the outside of the climbing frame 1 so that the channel assembly rises as the climbing frame 1 rises. When the tower crane driver needs to pass through the pedestrian passage, open the door panel 16 and flip and unfold the flip pedal 12 so that the flip pedal 12 overlaps with the tower crane standard parts of the corresponding height. When it is necessary to increase the height of the tower crane by adding the standard section 2, pull the iron chain to make the flip pedal 12 rotate in the opposite direction and retract to avoid the flip pedal 12 from interfering with the tower crane. In this embodiment, the spacing from the foot pedal to the tower crane standard section 2 is set to 120 mm. By setting a spacing of 120 mm, interference with the tower crane can be avoided as much as possible.

[0047] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
