[0001] The utility model relates to the technical field of tower crane passages, in particular to a detachable safety passage between a building construction machine and a tower crane. Background Art

[0002] During the construction of super high-rise projects, wall shrinkage often occurs. To meet the requirements of wall construction, the frame of the building construction machine will shrink inward synchronously with the wall. At the same time, during the construction of super high-rise projects, luffing tower cranes (hereinafter referred to as tower cranes) are often used as large lifting equipment.

[0038] Refer to Figure 1-8 In an embodiment of the present utility model, a detachable safety passage between a building construction machine and a tower crane includes a lower hanging frame body 1 of the building construction machine, a flap 2 and a pin assembly

[0039] On the side of the lower hanging frame body 1 of the building construction machine, a first support stress surface 11 is formed. On the lower hanging frame body 1 of the building construction machine, a first connecting member 12 is provided, and a horizontally arranged first connection hole 123 is formed in the first connecting member 12; on the side of the flap 2, a second support stress surface 21 is formed. On the flap 2, a second connecting member 22 is provided, and a horizontally arranged second connection hole 223 is formed in the second connecting member 22, and the second connection hole 223 is opposite to the first connection hole 123; on both sides of the flap 2 along its flipping direction, a detachable guardrail 3 is provided; a pin assembly (not shown) is detachably inserted into the first connection hole 123 and the second connection hole 223 to hinge the flap 2 to the lower hanging frame body 1 of the building construction machine;

[0040] Among them, in the first state, the flap 2 is horizontally arranged outside the lower hanging frame body 1 of the building construction machine, and the first support stress surface 11 and the second support stress surface 21 form an extrusion fit; the extrusion fit means that the first support stress surface 11 and the second support stress surface 21 are directly or indirectly in extrusion fit and support; by the first support stress surface 11 supporting the second support stress surface 21, the flap 2 can be horizontally arranged outside the lower hanging frame body 1 of the building construction machine, and one end of the flap 2 away from the lower hanging frame body 1 of the building construction machine overlaps on the tower crane, thereby forming a safety passage between the building construction machine and the tower crane.

[0041] In the second state, the flap 2 is flipped above the lower hanging frame body 1 of the building construction machine. Among them, when encountering bad weather such as typhoons and heavy snow, the flap 2 can be flipped above the lower hanging frame body 1 of the building construction machine. For example, the flap 2 in the first state is flipped 180°, avoiding the flap 2 hanging in the air outside, eliminating the falling risk existing in the flap 2, and eliminating the potential safety hazard in a short time; it should be noted that before flipping the flap 2 to the second state, the guardrails 3 on both sides of the flap 2 need to be removed first to avoid interference between the guardrails 3 and the lower hanging frame body 1 of the building construction machine.

[0042] In addition, the latch assembly is detachable, and the flap 2 of the corresponding length specification can be replaced according to the change of the distance between the building construction machine and the tower crane; and when replacing the flap 2, the flap 2 is first flipped to the top of the lower frame body 1 of the building construction machine, and the staff performs the disassembly and replacement operations on the lower frame body 1 of the building construction machine to ensure the safety of the staff working at high altitude. Specifically, the latch assembly can use a pin shaft with a pin head at one end, and a radial opening is provided on the other end of the pin shaft. After the pin shaft passes through the first connecting hole 123 and the second connecting hole 223, a bayonet is inserted into the radial opening on the pin shaft, so that the pin shaft cannot be separated from the first connecting hole 123 and the second connecting hole 223. When the latch assembly needs to be disassembled, the bayonet is pulled out and then the pin shaft is pulled out; the above-mentioned latch assembly is an existing structure, so no drawings are provided. In addition, other existing detachable latch assemblies can also be used to realize the hinge connection between the flap 2 and the lower frame body 1 of the building construction machine.

[0043] In some embodiments, Figure 1-3 As shown, at least two mounting tubes 23 are respectively arranged on both sides of the flap 2 along its flipping direction, the mounting tubes 23 are arranged vertically, and a plug hole 231 is formed in the mounting tube 23 and penetrates axially; the guardrail 3 includes an insertion rod 31 for inserting into the plug hole 231, and a limit block 32 is provided on the insertion rod 31, and the limit block 32 is mounted on the top of the mounting tube 23.

[0044] In this embodiment, the limit block 32 protrudes outside the insertion rod 31, and the limit block 32 cannot enter the insertion hole 231, so as to realize the vertical fixation of the guardrail 3. When the guardrail 3 needs to be disassembled, it is only necessary to pull up the insertion rod 31, without tools, and the operation is simple and quick, so as to achieve the purpose of folding the flap 2 in a short time. Preferably, in order to improve the installation stability of the guardrail 3, the insertion rod 31 passes downwardly through the installation tube 23 for a certain distance, preferably at least 120mm, so that the insertion rod 31 needs to move upward for a certain distance to be separated from the installation tube 23, so as to prevent the guardrail 3 from accidentally detaching from the installation tube 23 under the influence of external vibration factors. Among them, the height of the installation tube 23 is the same as the thickness of the flap 2, so as to prevent the installation tube 23 from protruding from the top surface of the flap 2 and affecting the flipping of the flap 2 to the lower bracket body 1 of the building construction machine.

[0045] In some embodiments, Figure 4-6As shown, the first connecting member 12 includes a first plate body 121, and the first plate body 121 is fixed on the first supporting stress surface 11; the upper end of the first plate body 121 extends above the top surface of the lower hanging frame body and forms a connecting portion 122, and the first connecting hole 123 is arranged on the connecting portion 122; the second connecting member 22 includes a second plate body 221, the second plate body 221 is fixed on the top of the flap 2, an ear plate 222 is arranged on the second plate body 221, and the second connecting hole 223 is arranged on the ear plate 222; in the first state, the second supporting stress surface 21 is pressed tightly on the first plate body 121.

[0046] Specifically, the installation position of the pin assembly, that is, the hinge joint of the flap 2 and the lower hanging frame body 1 of the building construction machine is located above the first supporting stress surface 11; the second supporting stress surface 21 presses the first plate body 121, thereby indirectly pressing the first supporting stress surface 11, so as to realize the countertop supporting stress between the second supporting stress surface 21 and the first supporting stress surface 11.

[0047] As Figure 4-6 shown, the first plate body 121 is fixed on the first supporting stress surface 11 through a bolt assembly. Wherein, the side surface of the lower hanging frame body 1 of the building construction machine itself is provided with an opening for installation on the building construction machine. In this embodiment, the opening on the lower hanging frame body 1 of the building construction machine is utilized, and the first plate body 121 is added to the outside of the lower hanging frame body 1 of the building construction machine, that is, on the first supporting stress surface 11, through the bolt assembly, which can reduce the preparation difficulty; correspondingly, an avoidance hole 211 is arranged on the second supporting stress surface 21 of the flap 2. In the first state, the avoidance hole 211 corresponds to the axial direction of the bolt assembly; thus, the bolt assembly can be inserted into the avoidance hole 211, so that the second supporting stress surface 21 can be pressed tightly on the first plate body 121. Among them, in order to improve the structural stability, the bolt assembly adopts 8.8 - grade bolts.

[0048] In some embodiments, as Figure 1 and Figure 2 shown, the flap 2 includes a square main board 2a, side plates 2b are fixedly arranged on the four sides of the main board 2a, the side plates 2b are perpendicular to the main board 2a, the second supporting stress surface 21 is the outer side surface of one of the side plates 2b, and a rib plate 2c arranged in a criss - cross manner is welded at the bottom of the main board 2a. In this way, the flap 2 can have a certain thickness to form the second supporting stress surface 21, the flap 2 is a hollow structure, which reduces the weight of the flap 2 and the load on the pin assembly and the lower hanging frame body 1 of the building construction machine; and, the overall structural strength of the flap 2 is enhanced through the rib plate 2c, ensuring that the flap 2 has sufficient strength to achieve stable bearing when personnel pass through.

[0049] In some embodiments, such as Figure 7 and Figure 8 shown, it further includes a support protection frame 4. The support protection frame 4 includes at least two support pipes 41 arranged at the bottom of the lower hanging frame body 1 of the building construction machine. A support plate 42 is welded to the bottom of the at least two support pipes 41. At least a part of the support pipe 41 extends beyond the vertical projection range of the lower hanging frame body 1 of the building construction machine. In the first state, the flap 2 is erected on the support pipe 41.

[0050] Wherein, in the second state, when the flap 2 is flipped onto the lower hanging frame body 1 of the building construction machine, the support plate 42 on the support protection frame 4 can be used to prevent the falling of construction materials and components. For example, when the flap 2 is disassembled and replaced, the support plate 42 can block the accidental falling of the pin assembly; at the same time, by supporting the flap 2 through the support pipe 41, the bearing capacity of the flap 2 in the first state can be further improved. The support pipe 41 can be made of square steel pipe, and the support plate can be made of iron sheet or metal mesh.

[0051] In some embodiments, such as Figure 1 and Figure 2 shown, there are three first connectors 12 on the lower hanging frame body 1 of the building construction machine and three second connectors 22 on the flap 2 respectively. By arranging a plurality of first connectors 12 and second connectors 22, the connection stability between the flap 2 and the lower hanging frame body 1 of the building construction machine is improved. Even if some of the pin assemblies are accidentally broken or detached, the falling risk of the flap 2 can be reduced.

[0052] In summary, the embodiment of the present utility model provides a detachable safety passage between the building construction machine and the tower crane. In bad weather such as typhoon and heavy snow, the flap 2 can be flipped above the lower hanging frame body 1 of the building construction machine, avoiding the flap 2 hanging in the air outside, eliminating the falling risk existing in the flap 2, and eliminating potential safety hazards in a short time; the pin assembly is detachable, and the flap 2 with a corresponding length specification can be replaced according to the distance change between the building construction machine and the tower crane; and when replacing the flap 2, first flip the flap 2 above the lower hanging frame body 1 of the building construction machine, and the staff can perform disassembly and replacement operations on the lower hanging frame body 1 of the building construction machine, ensuring the safety of the staff during high-altitude operations.

[0053] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
