Description

TECHNICAL FIELD

[0001] The present application relates to the field of building engineering, in particular to a hangar door and hoisting method. BACKGROUND

[0002] With the vigorous development of aviation industry, the scale and quantity of hangar construction are rising. As an important infrastructure for ensuring the parking, maintenance and repair of aircraft, the perfection degree of its supporting facilities is directly related to the efficiency and safety of aviation operation.

[0003] In the past hangar door installation engineering, the conventional method is to first split the hangar door structure to form a scattered piece structure. The scattered piece structure is standardized in the factory to realize batch production and is packaged according to the same specification. Then, the packaged scattered pieces are transported to the installation site of the hangar door. After arriving at the site, the construction personnel will assemble the scattered piece structure one by one on the ground in front of the hangar door opening, so as to combine it into a complete door whole. Finally, the hoist is used to hoist the assembled door as a whole and move it to the predetermined installation position. In the hoisting operation, the traditional way is to bind the hoisting rope at the hoisting point of the hangar door, and the hoisting rope is pulled by the crane to realize the hoisting operation of the hangar door.

[0004] However, when using this traditional hoisting method, that is, hoisting by binding the hoisting rope at the hoisting point of the hangar door, there is a obvious problem. Due to various factors in the hoisting process, such as shaking during hoisting, uneven distribution of the weight of the door, etc., the relative slip between the hoisting rope and the hangar door is prone to occur. This relative slip will directly cause the paint or plating layer on the surface of the hangar door to be abraded. Once the protective layer on the surface of the hangar door is damaged, the corrosion speed of the door will be accelerated, which will seriously affect the service life of the hangar door. SUMMARY

DETAILED DESCRIPTION

[0029] The following will be described in detail in combination with the accompanying Figures 1-12 The present application will be described in further detail.

[0030] Embodiment 1.

[0031] The present application discloses a hangar door and hoisting method.

[0032] Reference will be made to Figure 1 , Figure 2The utility model provides a hangar door, which comprises a guide rail 1 fixedly installed on the top wall of a door hole and a ground rail 2 fixedly installed on the bottom wall of the door hole, and a door frame 3 is arranged between the guide rail 1 and the ground rail 2.

[0033] Referring to Figure 2 , Figure 3 A shielding plate 4 is fixedly installed on the top side of the door frame 3 and is loosely inserted into the guide rail 1. The shielding plate 4 is provided with a first installation opening 5, and a guide wheel 7 is rotatably installed in the first installation opening 5. The shaft of the guide wheel 7 is vertically arranged. The guide wheel 7 cooperates with the guide rail 1 to play a guiding role, thereby improving the stability of the sliding of the hangar door.

[0034] Referring to Figure 3 , Figure 4 A mounting frame 8 is fixedly installed on the inner wall of the bottom side of the door frame 3, and the bottom side of the mounting frame 8 is provided with a second installation opening 6 penetrating through the bottom side of the door frame 3. A traveling wheel 9 is arranged in the second installation opening 6, the rotating shaft of the traveling wheel 9 is rotatably inserted into the inner side wall of the second installation opening 6, and the rotating shaft of the traveling wheel 9 is horizontally perpendicular to the length direction of the ground rail 2.

[0035] When the door frame 3 is placed between the guide rail 1 and the ground rail 2, the traveling wheel 9 is first placed in the mounting frame 8, and then the traveling wheel 9 is placed in the second installation opening 6 from the mounting frame 8, thereby facilitating the installation of the traveling wheel 9 on the door frame 3. The door frame 3 slides on the ground rail 2 through the traveling wheel 9.

[0036] Referring to Figure 5 , Figure 6 A connecting block 10, an ear plate 11, a first clamping plate 12, a second clamping plate 13 and a first bolt 14 are arranged on both sides of the door frame 3. The first clamping plate 12 is fixedly installed on one side of the connecting block 10 close to the door frame 3, the ear plate 11 is fixedly installed on the other side of the connecting block 10 away from the first clamping plate 12, and the ear plate 11 is provided with a hoisting hole 15. The second clamping plate 13 is located on the side of the first clamping plate 12 away from the connecting block 10, and the first clamping plate 12, the door frame 3 and the second clamping plate 13 are all provided with a first through hole 16 through which the first bolt 14 passes.

[0037] The first bolt 14 passes through the first clamping plate 12, the door frame 3 and the second clamping plate 13 in sequence, thereby fixing the connecting block 10 to the door frame 3, and then a hoisting vehicle is hoisted through the hoisting hole 15 in the ear plate 11. Compared with the traditional method of hoisting the door frame 3 after binding the door frame 3 with hoisting ropes, the paint or plating layer of the door frame 3 of the utility model is not easy to be abraded, thereby prolonging the service life of the hangar door.

[0038] After the hoisting of the door frame 3 is completed, the first bolt 14 is unscrewed, thereby facilitating the removal of the connecting block 10 and the ear plate 11 from the door frame 3 for repeated use.

[0039] Referring to Figure 3 , Figure 5 The door frame 3 is provided with a reinforcing rod 17, and the two ends of the reinforcing rod 17 are fixedly provided with a connecting plate 18. The connecting plate 18 is provided with a second bolt 19, and the connecting plate 18 and the lug plate 11 are both provided with a second through hole 20 through which the second bolt 19 passes. The door frame 3 is wide, and may be bent during hoisting. Reinforcement is performed through the reinforcing rod 17, so as to reduce the bending deformation of the door frame 3 during hoisting.

[0040] Referring to Figure 7 One side of the door frame 3 is fixedly provided with a veneer 21, and in another embodiment, both sides of the door frame 3 are fixedly provided with a veneer 21.

[0041] Referring to Figure 1 A hoisting method of a hangar door is applied to a hangar door of an embodiment of the present application, and includes the following steps: Step S1, installing a guide rail 1 at the top side of a door opening, and installing a ground rail 2 at the bottom side of the door opening.

[0042] Step S2, transporting components to a site to splice to form a door frame 3.

[0043] The components of the door frame 3 are produced in a factory and then transported to a construction site to splice to form the door frame 3.

[0044] Step S3, installing the door frame 3 on the guide rail 1 and the ground rail 2.

[0045] Step S4, after the door frame 3 is hoisted and positioned, installing light glass and thermal insulation plates on the outer side of the door frame 3 to form a veneer layer. At the same time, the connecting block 10 and the lug plate 11 are removed after the door frame 3 is hoisted and positioned.

[0046] Step S3 includes the following steps: Step S31, installing the connecting block 10 and the lug plate 11 on both sides of the door frame 3.

[0047] Step S32, gradually hoisting the door frame 3 through the lug plate 11 by two automobile cranes, and lifting the bottom side of the door frame 3 by a forklift and pushing the door frame 3 towards the door opening Step S33, when the door frame 3 is hoisted and inclined below the guide rail 1, the automobile crane slowly lifts the lifting arm, retracts the hoisting rope, and inserts the shielding plate 4 into the guide rail 1.

[0048] Step S34, after the door frame 3 is erected, installing the walking wheel 9 at the bottom side of the door frame 3 and the guide wheel 7 at the top side of the door frame 3.

[0049] The implementation principle of the hangar door and hoisting method in this application embodiment is as follows: a truck crane lifts the door frame 3 through the lug plate 11, and then the door frame 3 is hoisted between the guide rail 1 and the ground rail 2 for installation. Compared with the existing method of tying the door frame 3 with hoisting ropes for installation, this application is less likely to rub against the paint or plating on the surface of the door frame 3, thereby protecting the door frame 3 and extending the service life of the hangar door.

[0050] Example 2.

[0051] This application discloses a hangar door and a hoisting method.

[0052] Reference Figure 8 , Figure 9 The difference between this embodiment of the hangar door and Embodiment 1 is that support plates 22 are provided on both sides of the mounting frame 8, and the bottom side of the support plates 22 is fixedly connected to the inner wall of the bottom side of the door frame 3. An airbag 23 is fixedly installed on the side of the support plate 22 near the mounting frame 8. The airbag 23 is connected to a jet pipe 24. The end of the jet pipe 24 away from the airbag 23 is fixedly inserted through the bottom side of the door frame 3, and the end of the jet pipe 24 away from the airbag 23 is used to slide towards the ground rail 2. A compression mechanism 25 is installed on the mounting frame 8, which is used to compress the airbag 23.

[0053] As the hangar door slides along the ground track 2, the compression mechanism 25 repeatedly compresses the airbag 23. While the compression mechanism 25 compresses the airbag 23, the jet nozzle 24 sprays air into the ground track 2, thereby cleaning the track 2. When the compression mechanism 25 releases the airbag 23, the airbag 23 returns to its original position, facilitating the next compression by the compression mechanism 25.

[0054] Reference Figure 10 , Figure 11 The extrusion mechanism 25 includes a drive block 251, a drive frame 252, a drive rod 253, and a pressure plate 254. The drive block 251 is fixedly mounted on the rotating shaft of the traveling wheel 9. The drive frame 252 includes a first sub-plate 2521, a second sub-plate 2522, and a pin 2523. Both the first sub-plate 2521 and the second sub-plate 2522 are U-shaped and are interlocked end-to-end. A pin hole 26 for the pin 2523 to pass through is provided on one side of the top of both the first sub-plate 2521 and the second sub-plate 2522.

[0055] When installing the drive frame 252, the first sub-plate 2521 and the second sub-plate 2522 are positioned on both sides of the drive block 251. Then, after the first sub-plate 2521 and the second sub-plate 2522 are inserted end to end, the pin 2523 is inserted into the pin hole 26, so that the first sub-plate 2521 and the second sub-plate 2522 form the drive frame 252, and the drive frame 252 is sleeved on the drive block 251 and the rotation axis of the traveling wheel 9.

[0056] With reference to Figure 11 、 Figure 12 , the first sub-plate 2521 and the second sub-plate 2522 are both fixedly installed with sliding blocks 27, and the inner wall of the second mounting opening 6 is provided with a first sliding groove 28 for the sliding blocks 27 to slide along the length direction of the ground rail 2, so as to facilitate the sliding of the driving frame 252 along the length direction of the ground rail 2.

[0057] The inner wall of the second mounting opening 6 is provided with a second sliding groove 29 for the sliding blocks 27 to slide along the height direction, and the bottom end of the second sliding groove 29 is communicated with the first sliding groove 28. The sliding blocks 27 slide into the first sliding groove 28 from the second sliding groove 29, so as to facilitate the sliding installation of the first sub-plate 2521 and the second sub-plate 2522 on the inner wall of the second mounting opening 6. Then the first sub-plate 2521 and the second sub-plate 2522 are connected to form the driving frame 252, so as to facilitate the sliding installation of the driving frame 252 on the inner wall of the second mounting opening 6.

[0058] The distance between the two second sliding grooves 29 is greater than the width of the driving frame 252, so as to reduce the situation that the sliding blocks 27 slide out of the second sliding groove 29. When it is needed to take out the driving frame 252 from the second mounting opening 6, the driving frame 252 needs to be disassembled into the first sub-plate 2521 and the second sub-plate 2522, and then the first sub-plate 2521 and the second sub-plate 2522 are taken out respectively.

[0059] The slots of the first sliding groove 28 and the second sliding groove 29 are both provided with protrusions for limiting the sliding blocks 27 from falling out of the first sliding groove 28 and the second sliding groove 29. The sliding blocks 27 can only slide into the second sliding groove 29 from the first sliding groove 28, and then the sliding blocks 27 slide out of the top end of the second sliding groove 29.

[0060] With reference to Figure 10 、 Figure 12 , one end of the driving rod 253 is fixedly installed with a mounting block 31, and the side of the first sub-plate 2521 and the second sub-plate 2522 away from each other is provided with a third sliding groove 30 for the mounting block 31 to slide along the height direction. The slot of the third sliding groove 30 is provided with a protrusion for limiting the mounting block 31 from being pulled out of the slot of the third sliding groove 30, so that the mounting block 31 can only slide out of the top end and the bottom end of the third sliding groove 30. The other end of the driving rod 253 slides through the side wall of the mounting frame 8 and is fixedly connected with the pressing plate 254, and the pressing plate 254 is used for extruding the air bag 23.

[0061] The walking wheel 9 rolls to drive the driving frame 252 to rotate, so as to make the driving frame 252 move back and forth along the first sliding groove 28. When the driving frame 252 moves back and forth, the driving frame 252 drives the driving rods 253 on both sides to move back and forth, and the driving rods 253 repeatedly extrude the air bag 23 through the pressing plate 254, so as to facilitate the air jet pipe 24 to jet air to the ground rail 2 for cleaning.

[0062] The implementation principle of the hangar door and hoisting method is that when the hangar door slides along the ground rail 2, the walking wheels 9 continuously roll, so that the extrusion mechanism 25 repeatedly extrudes the air bag 23. When the air bag 23 is extruded, the air jet pipe 24 sprays air to clean the ground rail 2, thereby reducing the wear of the walking wheels 9 due to dust when sliding on the ground rail 2, and further prolonging the service life of the hangar door.

[0063] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
