Description

Technical Field

[0001] The utility model relates to the technical field of door crane traveling mechanisms, in particular to an adjusting and fixing device for a door crane traveling mechanism. Background Art

[0002] During the assembly process of the gantry crane, the traveling mechanism will be placed on the guide rail first, and the positions of the various traveling mechanisms of the gantry crane will be adjusted correctly. Then, each traveling mechanism will be fixed together with the guide rail. Then, a floating crane will be used to align the gantry and traveling mechanism on the gantry crane, and then the gantry and traveling mechanism will be docked.

[0003] In the prior art, publication number CN201371355Y discloses a door crane travel mechanism adjustment and fixing device. When in use, a set of the aforementioned fixing devices is installed on the guide rails on both sides of each set of the door crane's travel mechanism. Pulling the manual zipper tightens the chain of the hand chain hoist and the travel mechanism. The fixing card is subjected to the oblique force and firmly clamped on the guide rail, forming a temporary fixing point on the guide rail. Adjusting the chain of the hand chain hoist on both sides of the travel mechanism can change the position of the travel mechanism on the guide rail. After adjustment, the chain is locked, the position of the travel mechanism is fixed, and the door frame of the door crane and the travel mechanism are connected and assembled. After assembly, loosen the bolts and remove the fixing card to remove the temporary fixing point. Remove all the fixing devices and then use it for the installation of other door cranes. However, in the prior art, the fixing card is only stuck on the guide rail by the action of the oblique force, thereby cooperating with the manual hoist to fix the traveling mechanism. However, when the traveling mechanism moves abnormally fast on the guide rail, the traveling mechanism will pull the fixing card, causing the fixing card to easily slide quickly along the guide rail, and the fixing card cannot be stopped in time, posing a safety hazard. For this reason, those skilled in the art have proposed a door crane traveling mechanism adjustment and fixing device to solve the problems raised in the above background. Utility Model Content

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] See also Figure 1-Figure 5 A door crane travel mechanism adjustment and fixing device includes a guide rail 7 and a travel frame 1; a slide cavity 8 is formed on both sides of the guide rail 7, a connecting groove 2 is formed in the travel frame 1, and first sliders 6 are installed on both sides of the inner wall of the connecting groove 2 and are slidably connected to the slide cavity 8, and further includes:

[0023] Two groups of fixed blocks 9, each group of fixed blocks 9 is provided with two, and the fixed blocks 9 are provided with symmetrically distributed connecting holes 10, and the connecting holes 10 are provided with connecting bolts 11, and the fixed blocks 9 are provided with second sliders 12 slidably connected to the sliding cavity 8;

[0024] When the fixed block 9 is installed on the guide rail 7, the second sliders 12 of the two fixed blocks 9 are respectively inserted into the slide cavities 8 on both sides of the guide rail 7, and the connection holes 10 on the two fixed blocks 9 are aligned. Then, the two fixed blocks 9 are fixed together with bolts to complete the installation of the fixed block 9;

[0025] A connecting piece is provided between the fixed block 9 and the traveling frame 1 to connect the fixed block 9 to the traveling frame 1;

[0026] A traveling mechanism, which is arranged in the connecting groove 2 and is used to drive the traveling frame 1 to move along the guide rail 7;

[0027] The stopping mechanism is arranged in the fixed block 9 and is used to limit the abnormal rapid sliding of the fixed block 9.

[0028] When the present invention is in use, the first slide block 6 on the walking frame 1 is first connected to the sliding cavity 8 of the guide rail 7, so that the walking frame 1 can be placed on the guide rail 7, and then the two sets of fixed blocks 9 are installed in the positions on the guide rail 7, and the connecting pieces between the fixed blocks 9 and the walking frame 1 form a pulling force on both sides of the walking frame 1, so that the walking frame 1 can be fixed. When the walking frame 1 slides abnormally quickly, the connecting piece will drive the fixed block 9 to slide quickly on the guide rail 7. During the rapid sliding of the fixed block 9, the stopping mechanism will brake the fixed block 9, so that the fixed block 9 can be locked, and the walking frame 1 can be pulled by the connecting piece, and then the sliding walking frame 1 can be braked, which has a better use effect.

[0029] The connecting member includes a second connecting ring 14 arranged on the top of the fixed block 9, and a first connecting ring 13 is installed on both sides of the top of the walking frame 1. A connecting chain 15 is arranged between the first connecting ring 13 and the second connecting ring 14, wherein the connecting chain 15 can also be set as a manual hoist so that the length of the connecting chain 15 can be adjusted.

[0030] When the fixed block 9 is fixed on the guide rail 7, the connection between the fixed block 9 and the top of the walking frame 1 can be achieved through the first connecting ring 13, the second connecting ring 14 and the connecting chain 15. The walking frame 1 is pulled by the tension of the connecting chain 15, thereby fixing the walking frame 1.

[0031] The walking mechanism includes a rotating shaft 3 rotatably arranged in the communicating groove 2 , a moving wheel 4 is installed on the rotating shaft 3 , and a motor 5 connected to the rotating shaft 3 is installed on the outer wall of the walking frame 1 .

[0032] The traveling mechanism on the traveling frame 1 is used to realize the movement of the traveling frame 1. The motor 5 drives the rotating shaft 3 to rotate, so that the moving wheel 4 rotates, wherein the moving wheel 4 contacts the upper surface of the guide rail 7, so that when the moving wheel 4 rotates, the traveling frame 1 will also slide along the guide rail 7.

[0033] The stopping mechanism includes a movable shaft 17 rotatably arranged in the fixed block 9, a movable wheel 18 is installed on the movable shaft 17, a limiting frame 16 is installed on the top wall of the fixed block 9, a rotating disk 19 is installed on the movable shaft 17, an inner cavity 20 is opened in the rotating disk 19, and the inner cavity 20 is slidably connected to the movable frame 23, and limiting grooves 22 are opened on both sides of the inner cavity 20 in the rotating disk 19, and a limiting block 24 is slidably set in the limiting groove 22, and the limiting block 24 is connected to the movable frame 23, and the movable frame 23 is connected to a spring 21 connected to the inner cavity 20, and a block 25 is installed on the end of the movable frame 23 away from the spring 21, and slots 26 distributed at intervals are provided on both sides of the top of the guide rail 7.

[0034] When the walking frame 1 slides abnormally fast, the connecting piece will drive the fixed block 9 to slide quickly on the guide rail 7. During the fast sliding of the fixed block 9, the movable wheel 18 on the movable shaft 17 is also in contact with the upper surface of the guide rail 7. As the fixed block 9 slides quickly, the movable wheel 18 will rotate. When the movable rotation is too fast, the centrifugal force exerted on the moving frame 23 in the rotating disk 19 will also be greater. When the moving frame 23 slides toward the outside of the inner cavity 20 under the action of centrifugal force, the moving frame 23 will gradually extend. Due to the presence of the slot 26 on the guide rail 7, when the block 25 on the moving frame 23 extends, as the turntable rotates, the block 25 on the moving frame 23 will be stuck in the slot 26, thereby limiting the movable wheel 18 and making the fixed block 9 brake.
