Description
Technical field
The utility model belongs to bridge sluice control technology field, is specifically related to a kind of protective device of open/close machinery crane span structure.
Background technology
In prior art; the headstock gear of sluice is arranged on mechanical bridge; in the process that lock body is opened; due to operate miss, can cause forgetting disconnection starting switch, make screw mandrel drive lock body constantly to move upward; until contact bridge plate; thus bridge plate fracture or screw mandrel usually can be made in this case to bend, thus make whole equipment scrapping, cause huge loss.
Summary of the invention
In order to solve the problems referred to above that prior art exists; the utility model provides a kind of protective device of open/close machinery crane span structure; by the position corresponding with lock body in the below of bridge plate, steel plate is set; steel plate is installed the starting switch controlling the stop motion of lock body, after lock body touches steel plate, drives steel plate to move upward; bridge plate is made to touch starting switch; thus suspend the motion of lock body, prevent when nobody manipulates, the generation of the accidents such as lock body bursting bridge plate or damage screw mandrel.
The technical scheme that the utility model adopts is: a kind of protective device of open/close machinery crane span structure; comprise: standing screw and steel plate; described steel plate is arranged on the below of mechanical crane span structure by standing screw; the upper surface of described steel plate is provided with the starting switch controlling the opening and closing of lock body, described steel plate is corresponding with described lock body.
The further optimization of technical solutions of the utility model, described steel plate offers the through hole passed for keying screw mandrel, described through hole is positioned at the center of described steel plate.
The further optimization of technical solutions of the utility model, the number of described standing screw is at least two, and is arranged on uniformly on described steel plate.
The further optimization of technical solutions of the utility model, described standing screw is arranged with spring, and described spring is between described steel plate and described mechanical crane span structure.
The further optimization of technical solutions of the utility model, the upper surface of described steel plate is provided with a platform, described starting switch is arranged in described cylinder platform, and the button of described starting switch is higher than the upper surface of described cylinder platform, and the height of described cylinder platform is less than or equal to the height of described spring when compressing completely.
The further optimization of technical solutions of the utility model, the number of described standing screw is four, and the length of described screw rod is 40cm, and the thickness of described steel plate is 2cm, and four described standing screws are separately fixed on four angles of told steel plate.
The beneficial effects of the utility model are: by arranging starting switch on steel plate, control it and stop in the position of presetting, prevent lock body bursting bridge plate, cause the generation of security incident in the process that can rise at lock body; On screw rod, sheathed spring can make steel plate rise slowly in addition, also can protect starting switch simultaneously, prevent starting switch to be crashed to pieces; When upper surface of steel plate arrange a platform normally can work not affecting starting switch, protection starting switch is damaged or topple under extrusion, better reaches the effect of control.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, lock body; 2, mechanical crane span structure; 3, steel plate; 4, screw mandrel is opened and closed; 5, screw rod; 6, spring; 7, cylinder platform; 8, starting switch.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, will be described in detail the technical solution of the utility model below.Obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope that the utility model is protected.
As shown in Figure 1; the utility model provides a kind of protective device of open/close machinery crane span structure 2; comprise: standing screw 5 and steel plate 3; described steel plate 3 is arranged on the below of mechanical crane span structure 2 by standing screw 5; the upper surface of described steel plate 3 is provided with the starting switch 8 controlling the opening and closing of lock body 1, described steel plate 3 is corresponding with described lock body 1.
The further optimization of technical solutions of the utility model, described steel plate 3 offers the through hole passed for keying screw mandrel 4, described through hole is positioned at the center of described steel plate 3.
The further optimization of technical solutions of the utility model, the number of described standing screw 5 is at least two, and is arranged on uniformly on described steel plate 3.
The further optimization of technical solutions of the utility model, described standing screw 5 is arranged with spring 6, and described spring 6 is between described steel plate 3 and described mechanical crane span structure 2.
The further optimization of technical solutions of the utility model, the upper surface of described steel plate 3 is provided with a platform 7, described starting switch 8 is arranged in described cylinder platform 7, the button of described starting switch 8 is higher than the upper surface of described cylinder platform 7, and the height of described cylinder platform 7 is less than or equal to the height of described spring 6 when compressing completely.
The further optimization of technical solutions of the utility model, the number of described standing screw 5 is four, and the length of described screw rod 5 is 40cm, and the thickness of described steel plate 3 is 2cm, and four described standing screws 5 are separately fixed on four angles of told steel plate 3.
