Detailed description of the invention
As shown in Figure 1, a kind of automatic folding type steel pipe of the utility model tongs, comprises suspension ring 7 and two arms 12 and 16, is connected with respectively between 2, two connecting arms 2 of connecting arm and two arms 12 and 16 and is respectively hinged between described suspension ring 7 and two arms 12 and 16.
Between two hinge-points, be provided with locking clamp 10, one end of described locking clamp 10 and one of them hinge-point are hinged, between the other end of described locking clamp 10 and another hinge-point, it is card slot type clamping,, this end at locking clamp 10 is provided with a groove that Open Side Down, on this hinge-point, be provided with a bolt 11, in the time that locking clamp 10 is level attitude, this bolt 11 is embedded in the downward groove of (dialling) this end opening just, described arm 12 and 16 and described locking clamp 10 between be provided with automatic open/closing device;
Described automatic open/closing device comprises unblank transmission arm 14 and the reset weight 3 that are arranged on (be positioned at above a that) arm and are positioned at two arm joining places, described in unblank to connect by tie bolt 13 between transmission arm 14, reset weight 3 and arm 12 and 16.Described upper end of unblanking transmission arm 14 is provided with a pipe 142, as shown in Fig. 3-1; Described lower end of unblanking transmission arm 14 is arranged in the jaw that two arms form, as shown in Figure 1; Vertical with its axis first pin 143 that is welded with on described pipe 142, as shown in Fig. 3-1 and Fig. 3-2; Described reset weight 3 comprises weight plate 32, described weight plate 32 is provided with weight rotating hole 33 and two locating dowel pins 31 and 34, one of them locating dowel pin is the position of the moving connecting rod 5 of limitation lock, another locating dowel pin makes to lock connecting rod 5 and resets, the lower end of each locating dowel pin is equipped with screw thread, each locating dowel pin is fixed by weight plate 32 nut below, as shown in Fig. 2-1 and Fig. 2-2, described weight rotating hole 33 is coaxial with described pipe 142, as shown in Figure 1, unblank described in transmission arm 14 and described reset weight 3 relatively rotates.On described locking clamp 10, a side that is positioned at arm is provided with a groove, describedly unblank to be provided with between transmission arm 14 and described locking clamp 10 the moving connecting rod 5 of a lock, one end of the moving connecting rod 5 of described lock is provided with a lock untie-sell 6 coordinating with described locking clamp 10 upper grooves, the other end of the moving connecting rod 5 of described lock with described in unblank to be fixedly connected with by chain connecting bolt 4 between transmission arm 14, at natural relaxation state, lock clamp 10 in level, and when the draw-in groove of one end is stuck on tie bolt 11, one of the moving connecting rod 5 of lock corrects the groove of the centre that is arranged in locking clamp 10.As shown in Figure 1, (above that) arm 16 that is provided with automatic open/closing device is provided with the second pin 9 contacting with the first pin 143.
The initial condition (state while also not hanging steel pipe) that is illustrated in figure 1 tongs, the utility model tongs working process is included in two states and changes, and the one, start to lift steel pipe from initial condition, show and how steel pipe is held tightly; The 2nd, after having lifted, steel pipe is put down, after tongs opens automatically, in the process of tongs being hung away by crane, tongs is how to depart from steel pipe, describes working process below in detail.
Start to leave steel pipe to tongs from lifting, first from initial condition, tongs winches to steel pipe place by crane by suspension ring 7, owing to there being the restriction of draw-in groove on locking clamp 10, so in the process of lifting, the state of tongs is constant, or the same with initial condition, then the jaw two arms 12 and 16 being formed is placed on steel pipe, tongs toward fall process in, steel pipe can be encountered the transmission arm 14 of unblanking after entering jaw, because tongs is toward falling, so steel pipe can head on the transmission arm 14 of unblanking and up move, because the moving connecting rod 5 of lock is connected by tie bolt 4 with the transmission arm 14 of unblanking, in the process of up moving at the transmission arm 14 of unblanking, can head on the also up motion of the moving connecting rod 5 of lock, result is in the process of up motion, lock untie-sell 6 on the moving connecting rod 5 of lock will lock clamp 10 jack-up, make to lock clamp 10 one end groove that Open Side Down and left tie bolt 11.When tongs finds behind position, start lifting, because locking clamp 10 is departed from tie bolt 11 by jack-up, so now two connecting arms 2, no longer by locked, but can up move.On crane, carry; suspension ring 7 pull connecting arm 2 also toward rising; two arms 12 and 16 that are connected with connecting arm 2 are slowly held tightly simultaneously; gradually by steel pipe locking; because there is rubber 15 at the jaw place of the inner side at two arms, can avoid like this steel pipe directly to contact with tongs, this tongs can lift by crane the steel pipe of application; due to the protection of rubber 15, can be by scratch so do not worry being coated with the steel tube surface installing.When lifting steel pipes is arrived and formulated behind place, slowly fall, tongs also slowly falls, until locking clamp 10 one end groove that Open Side Down drops on tie bolt 11, and the transmission arm 14 of unblanking is now owing to being headed on by steel pipe, can continue the sideway swivel of turning left, result is to drive the skew of turning right of reset weight 3 and the moving connecting rod 5 of lock, because limited location pin 31 is holding in the palm the moving connecting rod 5 of lock, so it is larger that it can not depart from, and that groove in the middle of locking clamp 10 has also been left in the lock untie-sell 6 on the moving connecting rod 5 of lock, so when crane is mentioned tongs again, locking clamp 10 just can be by jack-up, two arms 12 and 16 can locking yet, so will very easily tongs be departed to steel pipe, depart from the process of steel pipe at tongs, because steel pipe no longer backs down lock transmission arm 14 gradually, under the Action of Gravity Field of reset weight 3, unblanking transmission arm 14 can be along with reset weight 3 left-hand revolution slowly, excessive for preventing the anglec of rotation, so be provided with one second pin 9 on arm, be used for limiting the position of the transmission arm 14 of unblanking, when reset weight 3 and the transmission arm 14 of unblanking pass through deadweight left-hand revolution, locating dowel pin 31 can be stirred the moving connecting rod 5 of lock and also do left-hand revolution, the transmission arm 14 of unblanking also can down drag moving lock connecting rod 5 by tie bolt 4, in the time that first on transmission arm 14 pin 143 of unblanking is encountered the pin of second on arm 9, lock untie-sell 6 on the moving connecting rod 5 of lock can just fall into that groove in the middle of locking clamp 10, from and replied initial condition, so carry out again the lifting of next steel pipe.
Although the utility model is described in conjunction with figure above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; in the situation that not departing from the utility model aim, can also make a lot of distortion, within these all belong to protection of the present utility model.
