Detailed Description
The present application is described in further detail below with reference to figures 1-4.
The embodiment of the application discloses a suspender antiskid device for segment vertical hoisting. Referring to fig. 1, the sling anti-slip device for vertically hoisting the duct piece comprises a fixing mechanism 1 for fixing the duct piece and a connecting mechanism 2 arranged on the fixing mechanism 1 and used for connecting hoisting equipment. Fixing mechanism 1 and coupling mechanism 2 all are provided with two sets ofly, and the both ends of love tube piece are installed respectively to two sets of fixing mechanism 1 and coupling mechanism 2, and fixing mechanism 1 includes mounting panel 11 and slidable mounting goes up centre gripping subassembly 12 and centre gripping subassembly 13 down on mounting panel 11, goes up centre gripping subassembly 12 and centre gripping subassembly 13 butt respectively on the upper surface and the lower surface of section of jurisdiction down.
Referring to fig. 1, the mounting plate 11 is vertically disposed, an upper fixing plate 111 and a lower fixing plate 112 are slidably mounted on the top and bottom of the mounting plate 11, the upper clamping assembly 12 is threadedly mounted on the upper fixing plate 111, and the lower clamping assembly 13 is threadedly mounted on the lower fixing plate 112. The upper clamping assembly 12 and the lower clamping assembly 13 are identical in structure, and the upper clamping assembly 12 and the lower clamping assembly 13 are symmetrically arranged about the mounting plate 11. The upper fixing plate 111 and the lower fixing plate 112 have the same structure.
Referring to fig. 2, the structure of the fixing plate 111 and the mounting plate 11 in the present embodiment is specifically described as an example. A vertical sliding groove is formed in the mounting plate 11, a vertical lead screw is mounted on the groove wall of the sliding groove, and a hand wheel is welded to the top of the lead screw. The upper fixing plate 111 is slidably mounted on the inner wall of the sliding chute, and the upper fixing plate 111 is in threaded fit with the lead screw. Two sections of threads with opposite directions are arranged on the upper section and the lower section of the screw rod, when a worker rotates the hand wheel, the screw rod can drive the upper fixing plate 111 and the lower fixing plate 112 to synchronously move in opposite directions or in opposite directions, and the worker can adjust the distance between the upper clamping assembly 12 and the segment, and the distance between the lower clamping assembly 13 and the segment by rotating the screw rod.
Referring to fig. 3, the upper clamping assembly 12 and the lower clamping assembly 13 are provided with a plurality of sets, which are specifically illustrated in this embodiment by taking three sets as an example, and the three sets of the upper clamping assembly 12 and the lower clamping assembly 13 are respectively and uniformly distributed on the upper fixing plate 111 and the lower fixing plate 112. A threaded hole is clamped on the upper fixing plate 111, and the upper clamping assembly 12 comprises a lifting rod 121 which is vertically arranged and is installed in the threaded hole in a threaded manner and a contact base 122 which is hinged at the bottom end of the lifting rod 121 by using a hinged base. A rubber seat is bonded to the lower surface of the contact seat 122. A force application nut 123 having a regular hexagonal cross-sectional shape is welded to the top of the lift rod 121.
When the staff was when the centre gripping section of jurisdiction, the spanner was established to the cover on application of force nut 123, uses the spanner to rotate lifter 121, and under the effect of screw thread, lifter 121 promoted the rubber seat on the contact base 122 lower surface, made the rubber seat butt on the upper surface of section of jurisdiction. Under the pushing of the lifting rod 121, the contact base 122 applies a certain pressure to the rubber pad 124 for a certain time, so that the rubber pad 124 is elastically deformed, and the contact area between the rubber pad 124 and the segment is increased.
Referring to fig. 4, a mounting lug is welded on the side of the top of the mounting plate 11 away from the upper clamping assembly 12, a vertical mounting hole is formed in the mounting lug, and the connecting mechanism 2 is rotatably mounted inside the mounting hole. The connecting mechanism 2 comprises a hook 21 with the bottom rotatably installed in the hole, an anti-falling rod 22 hinged on the tail part of the hook 21 and a spring 23 arranged between the hook 21 and the anti-falling rod 22. The free end of the hook 21 is in constant abutment against the inner wall of the hook 21 under the action of the spring 23.
The connecting rod of couple 21 bottom passes the mounting hole, and screw-thread fit has two positioning bolt 211 on couple 21 bottom connecting rod, and two positioning bolt 211 are located the top and the below of installation ear respectively. The positioning bolt 211 can restrict the position of the hook 21 while the hook 21 can be rotated inside the mounting hole. The staff can adjust the angle of couple 21 according to the actual conditions of job site to convenient construction. After the staff installed last centre gripping subassembly 12 and lower centre gripping subassembly 13, the staff pressed the free end of anticreep pole 22, made open the breach between the free end of anticreep pole 22 and couple 21, and the staff installed the suspender in the inside of couple 21 from the breach.
The implementation principle of the sling anti-slip device for vertically hoisting the duct piece is as follows: after the staff puts the section of jurisdiction well, use the hand wheel to rotate the lead screw, adjust the height of going up centre gripping subassembly 12 and centre gripping subassembly 13 down, make and go up centre gripping subassembly 12 and centre gripping subassembly 13 down and roughly be close to the upper surface and the lower surface of section of jurisdiction, later the staff uses the spanner to rotate lifter 121, finely tunes the height of contact base 122, makes the rubber seat butt on the surface of section of jurisdiction. Under the pressure applied by the contact base 122, the rubber pad 124 deforms, so that the contact area between the rubber pad 124 and the tube sheet is increased, and the stability of the clamping ground of the upper clamping assembly 12 and the lower clamping assembly 13 is improved. After the upper and lower clamp assemblies 12, 13 are installed, the worker installs the harness on the hanger 21.
Go up centre gripping subassembly 12 and centre gripping subassembly 13 down and exert certain pressure to the section of jurisdiction, increased the frictional force between the adjacent section of jurisdiction like this, frictional force can improve the stability of adjacent section of jurisdiction, and mounting panel 11 also sets up the tip at the section of jurisdiction simultaneously, and mounting panel 11, last centre gripping subassembly 12 and lower centre gripping subassembly 13 have reduced the section of jurisdiction and have taken place the possibility of slippage, have increased the stability of hoist and mount in-process section of jurisdiction.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
