Left and right pillar 1-3 is left and right vertically to be installed on discharging platform derrick 4 support bodys.Crossbeam 1-10 laterally is connected between the left and right pillar 1-3.Pulley 1-5 is installed in left and right pillar 1-3 top.Safety door 1-1 places between the left and right pillar 1-3, and haulage cable 1-2 lower end is attached on the safety door 1-1, and the upper end is walked around pulley 1-5 and linked to each other with counterweight 1-4, and counterweight 1-4 places in the left and right pillar 1-3 hollow wall.Safety door 1-1 lower end is provided with spring bumper 1-8.Left and right pillar 1-3 bottom is provided with the anti-fall mount pin 1-7 of counterweight.Link 1-6 upwards is connected in the middle of the safety door 1-1 top.Door is climbed 1-9 and is connected in both sides, safety door 1-1 bottom backward.
Referring to Fig. 1～4, combination hook with safety tong pair 2 is installed in the middle of the safety door system 1 crossbeam 1-10.It is formed referring to Fig. 5～6.By linking up with 2-1, two installation sheet 2-2, two installation bearing pin 2-3 and hitting hook sheet 2-4 and form.Two installation sheet 2-2 are forward and backward to be installed in the middle of the safety door system 1 crossbeam 1-10 side by side.Two installation bearing pin 2-3 will link up with 2-1 and hit hook sheet 2-4 and be movably hinged on two installation sheet 2-2, link up with 2-1 and hit hook sheet 2-4 to place in the middle of the two installation sheet 2-2.Make safety door hook 2-1 and hit hook sheet 2-4 and can in two installation sheet 2-2, freely rotate.
As Fig. 6, hook 2-1 front end is hook-shaped, and it is forked that the rear end is, and hits hook sheet 2-4 front end and is match with hook 2-1 rear end forked.
Combination hook with safety tong secondary 2 total Fig. 7,10,15 3 kind of mode of operation, concrete combining mechanism principle is introduced.
Referring to Fig. 1～2, cage accessory system 3 is installed in the discharging platform derrick 4.Its structure such as Fig. 3～4, by movable lift block 3-1, spring assembly 3-2, on touch ring 3-3 and touch down and encircle 3-4 and form.
Movable lift block 3-1 rear end is articulated in side lower part both sides before the cage 5 that places in the discharging platform derrick 4, and to climb the 1-9 position corresponding with the door that is installed on both sides, safety door system 1 safety door 1-1 bottom.Movable lift block 3-1 front end links to each other with spring assembly 3-2 one end, and the spring assembly 3-2 other end links to each other with cage 5.On touch ring 3-3 and upwards be installed on forward in the middle of the cage 5 front sides tops, with the combination hook with safety tong pair 2 that is installed on safety door system 1 crossbeam 1-10 centre to hit hook sheet 2-4 position corresponding.Under touch ring 3-4 and be installed on forward before the cage 5 in the middle of the side lower parts, with on to touch ring 3-3 position corresponding.All members of native system all can be with cage one lifting.
Principle of work:
Mode of operation when Fig. 1 and Fig. 2 are in bottom for cage 5.When cage 5 rose, the movable lift block 3-1 on the cage rose with cage 5, met to drive safety door behind the safety door 1-1 and rise together, and arrived position shown in Figure 8.This moment, link 1-6 contacted hook 2-1 at the C point, the hook 2-1 link 1-6 contact the inclined-plane, lower edge to P to shrinking back, the enlarged drawing of its effect as shown in Figure 9, the position that make up the hook 2-1 in the hook with safety tong pair 2 and hit hook sheet 2-4 this moment is hit hook sheet 2-4 front fork and is linked up with the 2-1 back vent and intersect and cooperate as shown in figure 10.Link 1-6 is placed in the middle of the hook 2-1, and continue to rise with cage 5 and withstand hook 2-1 top and out of service, when cage 5 continues to rise, spring assembly 3-2 elongates under the drag effect of safety door 1-1, the movable downward run-off the straight of lift block 3-1 and climb 1-9 with door and come off, safety door 1-1 by gravity glides, hook 2-1 is returned to Fig. 5 in advance under himself action of gravity, 6 and state shown in Figure 7, link 1-6 is suspended on the hook 2-1 reposefully, cage 5 can carry out operation safely after arriving safety door place layer, its position as shown in figure 11, its partial enlarged drawing is as shown in figure 12.
When finishing from the operation of Figure 11 position, cage 5 returns downwards the surface process, on touch the mirror hook sheet 2-4 that ring 3-3 will bump against combination hook with safety tong pair 2 from the top downwards, hitting hook sheet 2-4 is rotated down last touching under the pressure effect that encircles 3-3, drive hook 2-1 rotation and withdraw from link 1-6, at this moment, the state of combination hook with safety tong pair 2 still as shown in figure 10, under the action of gravity of safety door 1-1, safety door 1 and cage 5 are got back to the virgin state of Figure 1 and Figure 2.
Need position from Figure 11 when last layer moves as cage 5, touch down ring 3-4 (seeing Figure 13,14) in uphill process will P point from below upwards bump against make up hook with safety tong pair 2 hit hook sheet 2-4, hitting hook sheet 2-4 rotates up under the top power effect of touching ring 3-4 down, drive hook 2-1 rotation and withdraw from link 1-6, at this moment, the state of combination hook with safety tong pair 2 as shown in figure 15.Under the action of gravity of safety door 1-1, safety door 1-1 gets back to lower floor's virgin state, and cage 5 then rises to the last layer operation.
Certainly, the upper strata work layer also should install this discharging platform protective door additional.
