Technical Field

[0001] The utility model relates to the technical field related to construction engineering, in particular to a splicable anti-overturning tower crane access passage. Background Art

[0002] The tower cranes at construction sites are quite high, and usually the crane drivers are required to climb the steel ladder inside the tower to reach the cab. Given that the tower is a certain distance from the building structure, construction sites need to make access passages to the tower cranes so that the crane drivers can reach the cab quickly and safely to work.

[0003] Traditional tower crane access roads are usually manufactured by on-site welding, which is time-consuming and labor-intensive. In addition, due to the low degree of standardization, their scope of use is very limited. After being used at the current construction site, they cannot be effectively transferred to the next construction site for continued use, thus failing to achieve the purpose of standardized use.

[0026] See also Figure 1-Figure 6 In an embodiment of the utility model, a connectable anti-overturning tower crane access passage comprises a first passage 1 and a second passage 2;

[0027] The first channel 1 and the second channel 2 have the same structure, and a fastening connection mechanism is provided between the two, and the fastening connection mechanism can combine the first channel 1 and the second channel 2 to form a tower crane access channel;

[0028] The first channel 1 includes a steel trough 101 and a patterned steel plate 102 disposed in the steel trough 101. The patterned steel plate 102 is welded in the steel trough 101. Vertical enclosure structures are disposed on both sides of the steel trough 101.

[0029] A stabilizing structure is also provided between the vertical enclosure knot and the patterned steel plate 102 . The stabilizing structure is triggered when the vertical enclosure structure is connected to the steel trough 101 , and cooperates with the patterned steel plate 102 .

[0030] Please refer again Figure 4 , Figure 5 as well as Figure 6 The vertical enclosure structure includes a plurality of first square tubes 103 arranged at the side of the steel channel 101 and distributed along the length direction of the steel channel 101, and a second square tube 104 fixedly connected to one end of the plurality of first square tubes 103 away from the steel channel 101. The steel channel 101 is provided with a deep groove 106, which is adapted to the first square tube 103 and is used for the first square tube 103 to be plugged into the steel channel 101, and a footboard 105 is fixedly provided on the outer side of the plurality of first square tubes 103.

[0031] For example, in actual construction, the overall length of the first channel 1 is 4m, the overall length of the second channel 2 is 2m, the thickness of the patterned steel plate 102 is 3mm, the specifications of the first square tube 103 are 30*30*2, and the specifications of the second square tube 104 are 50*50*3.

[0032] Specifically, in actual use, the patterned steel plate 102 is placed in the steel groove 101, and the patterned steel plate 102 is welded to the steel groove 101, then the first square tube 103 is inserted into the deep groove 106, and then the first square tube 103 and the steel groove 101 are welded, then the footboard 105 is installed, and the second square tube 104 is used to connect the ends of the plurality of first square tubes 103 away from the steel groove 101, so that the plurality of first square tubes 103 can form a stable enclosure plane;

[0033] When the first square passage 103 is inserted into the deep groove 106, the stabilizing structure is triggered and moves toward the patterned steel plate 102 to enhance the stability of the connection between the patterned steel plate 102 and the steel groove 101 and enhance the safety of passage.

[0034] Please refer again Figure 6 The inner side of the steel groove 101 is also provided with a through groove 107, the through groove 107 is connected with the steel groove 101, and the stable structure includes a follower 3 slidably arranged in the through groove 107;

[0035] The follower 3 includes a triangular portion 301 and a rectangular portion 302 , and the inclined surface 303 on the triangular portion 301 cooperates with the end of the first square passage 103 away from the second square passage 104 . The side of the patterned steel plate 102 is also provided with a plurality of positioning openings 108 adapted to the rectangular portion 302 .

[0036] During use, after the patterned steel plate 102 and the steel groove 101 are welded, the follower 3 is located in the deep groove 106. Subsequently, when the first square tube 103 is inserted into the deep groove 106, the first square tube 103 will squeeze the rectangular portion 302. Under the action of the inclined surface 303, the follower 3 will gradually slide toward the patterned steel plate 102 through the through groove 107. Accordingly, the rectangular portion 302 is inserted into the positioning port 108. In this way, the connection strength between the patterned steel plate 102 and the steel groove 101 is greatly improved, ensuring the safety of the channel during construction.

[0037] Preferably, an interference fit is adopted between the rectangular portion 302 and the positioning opening 108 to further improve the stability of the overall structure of the channel.

[0038] Please refer again Figure 3 and Figure 4 The fastening connection mechanism includes a stiffening steel plate 5 arranged at the bottom of the first channel 1 and the second channel 2, and threaded holes 4 are provided on the stiffening steel plate 5 and the patterned steel plate 102, and fastening bolts 6 are provided in the threaded holes 4 to fix the first channel 1 and the second channel 2.

[0039] Preferably, the specification of the reinforcing steel plate 5 is 900mm*80mm, the threaded hole 4 is a φ16 bolt hole, and the fastening bolt 6 is an M12 bolt;

[0040] In order to adapt to different channel length requirements, when the first channel 1 and the second channel 2 are spliced, a reinforcing steel plate 5 is added, and holes are opened according to the spacing between the lower threaded holes 4 of the first channel 1 and the second channel 2, and M12 bolts are used for perforation connection and fixing to achieve the purpose of standardized splicing.

[0041] Please refer to Figure 3 The first channel 1 and the second channel 2 are both provided with vertical poles 7, and the vertical poles 7 are clamped with the two ends of the horizontal transverse web of the standard section of the tower crane, and are fixed by bolts through holes, so that the tower crane access channel is effectively connected with the tower crane.

[0042] The vertical pole 7 can be clamped at both ends of the horizontal transverse web of the standard section of the tower crane and fixed by bolts through holes, so that the tower crane access passage is effectively connected to the tower crane and achieves the function of anti-overturning.

[0043] In general, in the face of specific on-site construction conditions, the 4m long first channel 1 (non-standard part) and the 2m long second channel 2 are connected and fixed through a 900*80 stiffening steel plate 5 with φ16 bolt holes and M12 bolts. If a channel longer than 6m is required, a channel stiffening steel plate 5 and bolts can be added to fix and splice a 2m long second channel 2 through holes, so as to achieve the purpose of lengthening the channel, facilitate installation, and greatly improve the degree of standardization;

[0044] Therefore, the utility model avoids the time-consuming and laborious on-site welding processing of the tower crane access channel, improves the degree of standardization and ease of use, and the component can be reused to a certain extent. After being used at the current construction site, it can be used in other construction sites, avoiding waste of resources and achieving the purpose of reducing costs.
