Description
The technical field is as follows:
the utility model relates to a construction equipment field relates to a box prevents pounding temporary bridge particularly.
Background art:
in the building construction process, the situation that the gap of two adjacent structures needs to be penetrated through often appears, and when the gap is great, people just need to set up the access bridge, make things convenient for the transportation of material and the passing through of personnel. Can adopt the mode of setting up the springboard usually at present, but adopt this kind of mode, often the standardization of access bridge is lower, and the reliability that faces the frontier defense and protect is low, has the potential safety hazard that material and personnel fall, and unobstructed, the effect of blocking when not using often appears personnel mistake entering access bridge's the condition in the unable effect of accomplishing to use of this kind of access bridge simultaneously, has increased safe risk coefficient. In addition, materials are often required to be lifted through the gap between two structures, and the temporary bridge forms an obstacle and influences normal construction production. After the construction is finished, the temporary bridge dismantling process is complicated, the material packing and transporting workload is large, the measure cost is increased, and the construction progress is influenced.
The invention content is as follows:
the utility model aims to solve the technical problem that a box formula of simple structure, ann tear open convenient, can have enough to meet the need the use prevents pounding suspension bridge, has solved current suspension bridge measure and has had the problem that the process is loaded down with trivial details, the safe risk is high and influence the construction progress.
The above object is achieved by: it includes the body frame body, characterized by: the left side and the right side of the front end of the main frame body are respectively provided with a slideway, the left end and the right end of the reticular protective door are both fixed with a slide block, and the slide blocks at the left end and the right end of the protective door are respectively matched and installed with the slideways at the left side and the right side of the main frame body;
the rear end of the pedal is hinged at the bottom of the front end of the main frame body;
the two lower pulleys are respectively arranged in the middle of the left end and the right end of the main frame body through shafts, the upper pulleys are respectively arranged at the top of the left end and the right end of the main frame body through shafts, the two lower pulleys also comprise two steel wire ropes, one ends of the two steel wire ropes are respectively fixed at the left end and the right end of the front part of the pedal, and the other ends of the two steel wire ropes are respectively fixed at the left end and the right end of the lower part of the protective door after passing through the lower pulleys and the upper pulleys which are positioned at the same side.
The left end and the right end of the pedal are both fixed with guardrails extending upwards.
An upper-layer anti-smashing plate is fixed at the top of the main frame body, and a lower-layer anti-smashing plate is fixed on the main frame body below the upper-layer anti-smashing plate. The weight of the pedal is equal to the weight of the protective door.
The utility model has the advantages that:
1, this device has replaced the method of setting up springboard temporary bridge at two adjacent structure both ends, and this device can have enough to meet the need reuse, and material saving, reduce cost can carry as required at any time fast, and convenient and fast has solved loaded down with trivial details process in the past, reduces the work and material loss, effectively practices thrift the cost, has shortened construction period simultaneously.
2, the device only needs one-time assembly, is convenient to assemble and easy to operate, and saves time and improves efficiency. The device is particularly suitable for construction sites which can not set a groove for fixing the access bridge passage for a long time or need to lift materials through the groove.
3, the open state of the device is a safe and firm access bridge, and the closed state is reliable edge protection, so that the safety of a construction site is ensured.
Description of the drawings:
FIG. 1 is a schematic structural view of the protection door in the open state of the present invention;
FIG. 2 is a schematic side view of the open state of the protective door according to the present invention;
fig. 3 is a schematic front view of the protection door of the present invention in a closed state;
fig. 4 is a side view schematic structural diagram of the closed state of the middle protective door of the present invention.
The specific implementation mode is as follows:
the present invention will be further described with reference to FIGS. 1-4;
the main frame body 1 is provided with slideways 2 on the left and right sides of the front end of the main frame body respectively, sliders are fixed at the left end and the right end of a reticular protective door 3, and the sliders at the left end and the right end of the protective door are respectively matched and installed with the slideways on the left and right sides of the main frame body;
the rear end of the pedal 4 is hinged at the bottom of the front end of the main frame body;
the two lower pulleys 5 are respectively arranged in the middle of the left end and the right end of the main frame body through shafts, the upper pulley 6 is respectively arranged at the top of the left end and the right end of the main frame body through shafts, the two lower pulleys also comprise two steel wire ropes 7, one ends of the two steel wire ropes are respectively fixed at the left end and the right end of the front part of the pedal, and the other ends of the two steel wire ropes are respectively fixed at the left end and the right end of the lower part of the protective door after passing through the lower pulleys and the upper pulleys which are positioned at the same side.
