Trigger hole 510 lateral wall and run through and seted up hole 530 of stepping down, and locking pole 53 wears to establish hole 530 of stepping down and can follow hole 530 endwise slip of stepping down, and locking spring 54 is located and triggers hole 510, and locking spring 54 and locking pole 53 coaxial line, locking spring 54's one end with trigger hole 510 inside wall fixed connection, the other end and locking pole 53 fixed connection to with locking pole 53 orientation outside promoting of stepping down hole 530. The locking pole 53 is located the one end fixedly connected with inserted bar 55 in triggering the hole 510, and the axial of inserted bar 55 is unanimous with the axial of triggering the hole 510, and the jack 550 has been seted up to the trigger block 51 diapire, and inserted bar 55 clearance fit ground is inserted and is established to the jack 550 in. The inside wall of the walking groove 210 is provided with a plurality of locking holes 56 for the locking rod 53 to be inserted, the number of the locking holes 56 is more than 2, and the plurality of locking holes 56 are at least arranged through one locking hole 56 along the circumference of the walking groove 210 in a uniformly distributed manner and any radius of the walking wheel 21.

In the process of pouring the outer side retaining wall, the walking wheels 21 are located above the trigger blocks 51, the trigger blocks 51 are pressed downwards at the bottoms of the walking wheels 21, the trigger blocks 51 and the locking rods 53 are located in the states, when the walking wheels 21 are lifted upwards, the trigger blocks 51 move upwards under the action of the trigger springs 52, the inserted rods 55 are pulled out of the insertion holes 550, then the locking springs 54 can eject the locking rods 53 out of the abdicating holes 530 and insert the locking rods into any locking hole 56, automatic locking of the walking wheels 21 is achieved, and the walking wheels 21 are prevented from being completely tilted upwards and separated from the walking track 11.

Referring to fig. 9, the bottom wall of the traveling base 22 is further fixedly connected with a pre-pressing plate group 6, and the pre-pressing plate group 6 is located on one side of the traveling wheel 21 facing the traveling direction. The set of preload plates 6 includes a lock maintaining plate 61, a lock pressing plate 62, a trigger maintaining plate 63, and a trigger pressing plate 64. The locking maintaining plate 61 is attached to the side wall of the traveling rail 11 where the receding hole 530 is formed, and the locking pressing plate 62 is connected to one end of the locking maintaining plate 61 facing the traveling direction of the traveling mechanism 2, and one end of the locking pressing plate 62 away from the locking maintaining plate 61 is inclined in a direction away from the traveling rail 11. The locking pressing plate 62 can contact with the locking rod 53 first in the process of traveling with the traveling seat 22, and gradually press the locking rod 53 until the end portion is completely contracted into the receding hole 530, and the locking maintaining plate 61 can make the locking rod 53 keep the aforementioned state.

The trigger maintaining plate 63 is attached to the top wall of the traveling rail 11, the trigger pressing plate 64 is connected to one end of the trigger maintaining plate 63 facing the traveling direction of the traveling mechanism 2, and one end of the trigger pressing plate 64 far away from the trigger maintaining plate 63 is arranged to be inclined in the direction far away from the traveling rail 11. Further, the lock pressure plate 62 is located on one side of the trigger pressure plate 64 in the traveling direction of the travel mechanism 2. The trigger pressing plate 64 may contact the trigger block 51 during the process of traveling with the traveling base 22, and gradually press the trigger block 51 until the end portion is completely contracted into the trigger hole 510, and may allow the insertion rod 55 to be inserted into the insertion hole 550, and the trigger maintaining plate 63 may allow the trigger block 51 to maintain the aforementioned state. In summary, the pre-pressing plate set 6 can make the traveling wheel 21 move to the next station, so that the trigger block 51 and the locking rod 53 are already in the contracted state.

The implementation principle of the embodiment 2 is as follows: in the process that the traveling wheels 21 roll along the traveling rails 11, the pre-pressing plate group 6 is in contact with the automatic locking module 5 in advance, and the process is as follows: the locking pressing plate 62 can contact with the locking rod 53 firstly in the process of traveling along with the traveling seat 22, gradually extrude the locking rod 53 until the end part is completely contracted into the yielding hole 530, and the locking maintaining plate 61 can enable the locking rod 53 to keep the state. The trigger pressing plate 64 may contact the trigger block 51 during the process of traveling with the traveling base 22, and gradually press the trigger block 51 until the end portion is completely contracted into the trigger hole 510, and may allow the insertion rod 55 to be inserted into the insertion hole 550, and the trigger maintaining plate 63 may allow the trigger block 51 to maintain the aforementioned state. In summary, the pre-pressing plate set 6 can make the traveling wheel 21 move to the next station, so that the trigger block 51 and the locking rod 53 are already in the contracted state.

Then, the walking wheel 21 rolls to a designated position, at the moment, after the walking wheel 21 follows the trigger maintaining plate 63, when the trigger maintaining plate 63 gradually separates from the trigger block 51, the walking wheel 21 gradually rolls to the position above the trigger block 51, when the walking wheel 21 completely rolls to the position above the trigger block 51, the trigger maintaining plate 63 separates from the trigger block 51, the locking maintaining plate 61 does not cover the abdicating hole 530 any more, and then pouring construction can be carried out. Under this state, if take place running gear 2 unbalance, when leading to walking wheel 21 to have the action of upwarp, in case walking wheel 21 upwarps for a short time, trigger block 51 breaks away from walking wheel 21's pushing down, trigger block 51 goes upward under trigger spring 52 effect for inserted bar 55 takes out from jack 550, locking spring 54 can be with the ejecting hole 530 of stepping down of locking pole 53 and insert and establish to arbitrary locking hole 56 afterwards, in order to realize walking wheel 21's automatic locking, prevent that walking wheel 21 from warping completely and breaking away from walking track 11, thereby the holistic security of equipment has been promoted.

In addition, when constructor need move to work platform 31 and operate, need earlier the artifical top of with inboard protection network 25 and stimulate downwards, can promote balancing weight 23 outside the weight hole 230 through linking rope 29 this moment automatically to the arm of force of balancing weight 23 has been increased, makes running gear 2 and the holistic focus of balancing weight 23 skew towards the center department of decking 1, even makes running gear 2 whole more stable. When constructor need not to use work platform 31, can slide balancing weight 23 into counterweight hole 230 and realize accomodating, the constructor of being convenient for carries out other construction operations or supplies other construction equipment normal current to the roof of decking 1. And at this moment, the top of the inner side protection net 25 can be driven to move upwards under the action of the linkage rope 29, so that the inner side protection net 25 can automatically ascend, and the safety protection is more convenient.

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.
