The specific embodiment
Lifting false work that first embodiment of the invention provides bottom automatically the load safety as shown in Figure 2, this safety comprises: fixed structure 1, a motion structure 2, resetting-mechanism 3, haulage gear 4 and top wheel 5.This fixed structure 1 is connected with the scaffold support body.
Wherein, motion structure 2 is an approximate cuboid, and the one end has a junction, and its other end is the support portion, and the upside of support portion is provided with the inclined-plane and forms Wedge-shape structures, and this inclined-plane is to be used to structure that motion structure 2 power of being squeezed are slided.The connecting portion of this motion structure 2 is in fixed structure 1 and with fixed structure 1 and is slidingly connected, and both can slide relatively.The support portion of this motion structure 2 is used to be erected at the construction wall structure.Two sides of this motion structure 2 are respectively arranged with an outstanding alignment pin 21, and fixed structure is provided with corresponding chute 11, and both cooperate installation, are used for carrying out spacing to motion structure 2 with the relative slip of fixed structure 1.
Haulage gear 4 is used to allow the user to order about motion structure 2 to slide with respect to fixed structure 1.Haulage gear 4 comprises: flexible strand part 41, directive wheel 42, traction element 43 and positioning element 44.Wherein, traction element 43 is configured for triggering the triggering structure that resets after haulage gear 4 actions with positioning element 44.One end of flexible strand part 41 is connected with the connecting portion of motion structure 2, and the other end is connected with traction element 43.42 of some directive wheels are fixed on the fixed structure 1, and can rotate around the axis, and are used to guide and change the laying route of flexible strand part 41.Thereby operation traction element 43 tension flexible strand parts 41 are driven motion structure and are slided with respect to fixed structure 1.When motion structure 2 when initial position is towed to a certain position, can position by 44 pairs of traction elements 43 of positioning element, thereby make motion structure 2 can remain on this position.In the present embodiment, traction element 43 is a rigid rod 43a, and the body of rod diameter of this rigid rod 43a is greater than the diameter of flexible strand part 41.The front end of rigid rod 43a is a small end, connects described flexible draw cord 41, and its other end is provided with the 43b of holding portion that a diameter is slightly larger than body of rod diameter.This rigid rod 43a that stretches can actuation movement structure 2.Accordingly, positioning element 44 is a locating hole 44a.As shown in Figure 4, this locating hole 44a is made up of a circular hole and an elongated slot, the diameter of circular hole is between the body of rod diameter and the 43b of holding portion diameter of described rigid rod 43a, and the width of elongated slot is between the body of rod diameter and point diameter of described rigid rod 43a, and circular hole and elongated slot are connected.The circular hole of this locating hole 44a allows the body of rod of rigid rod 43a to pass, but its diameter stops holding portion to pass through less than the holding portion of rigid rod 43a.And the width of the elongated slot of locating hole 44a is between the diameter of the body of rod diameter of rigid rod 43a and flexible strand part 41, thereby allows flexible strand part 41 to pass through by the body of rod that stops rigid rod 43a.When motion structure 2 was positioned at initial position, this rigid rod 43a passed the circular hole of locating hole 44a, and the 43b of its holding portion is stuck.Thereby traction rigid rod 43a actuation movement structure 2, all pass the circular hole of locating hole 44a and flexible strand part 41 when entering this circular hole up to the body of rod of rigid rod 43a, horizontal mobile rigid rod 43a makes flexible strand part 41 be moved in the elongated slot of locating hole 44a, this moment, the body of rod of rigid rod 43a was blocked by elongated slot, thereby motion structure 2 is positioned at the position, back of sliding.At this moment, the support portion of motion structure 2 also enters in the fixed structure 1.
Resetting-mechanism 3 is one to be placed in the connecting portion of motion structure 2 and the elastic body between the fixed structure 1, is used to order about motion structure 2 and is returned to its initial position and remains on initial position from the position, back of sliding.In the present embodiment, this elastic body is a spring.As shown in Figure 2, the connecting portion of motion structure 2 is provided with fixed leg 22, and spring housing is contained on the fixed leg 22 and an end of spring supports only on the connecting portion of motion structure 2.Fixed structure 1 is provided with corresponding baffle plate 14, and this baffle plate 14 is provided with the through hole that allows fixed leg 22 to pass.The other end of spring resists on baffle plate 14.When motion structure 2 is positioned at initial position, motion structure 2 is applied elastic force makes motion structure 2 remain on initial position thereby spring is in a little compressive state.Slip is spacing up to using 44 pairs of traction elements of positioning element 43 to carry out relatively when pulling traction element 43 makes motion structure 2, and spring is further compressed.When traction element 43 during from spacing freeing, the restoring force of this spring affacts on the motion structure 2, makes motion structure 2 slide into its initial position and remains on initial position.
The top wheel 5 of tape spool rotation only is used for supporting in the construction wall structure, and can rotate around the axis.As shown in Figure 2, the bottom of the end that an end of fixed structure 1 promptly is slidingly connected with motion structure 2 is provided with installing plate 12, and top wheel 5 is installed on the installing plate 12.The part of mounted top wheel 5 protrudes in outside the edge of fixed structure, contacts with the construction wall structure with convenient.
