Description

Earthquake life bed

The utility model is a kind of earthquake life bed, belongs to human protection life technical field.

At present, earthquake is in the world to a kind of natural calamity of human extent of injury maximum, does not also have what effective method to control it up to now.

The purpose of this utility model be according to all violent earthquakes occur in local morning on the same day a bit about the time people in bed characteristics all, invent a kind of doss that can automatic emergency lifesaving when almost taking place and avoids injures and deaths with the help bed staff with earthquake.

The utility model is lifesaving bed, and effect at ordinary times is the same with general doss, sees Fig. 1.When earthquake takes place, it has and can be barricaded as a triangle frame by two blocks of overcanopy carrier bars automatically on bed surface when almost taking place with earthquake, under bed surface by the front and back end plate, both sides turnover panel and bed base plate constitute a bed basin, make the whole bed body form the lifesaving system of a closed cylinder, hit the unique effect of avoiding injures and deaths to assist the bed staff to resist, see Fig. 2.

Fig. 3 and shown in Figure 4 be that structure of the present utility model is formed, wherein components A is a lathe bed, part B is that last back the preceding of guide groove that have with nut check of support leans on before being sleeved on lathe bed, parts C is sleeved on the back backstop that has guide groove with nut check on the back brace, parts D is inlaid in overcanopy carrier bar in the relevant parts guide groove with its two ends guide head group, part 1 and 2 is the guide plates that are sleeved on the both sides turnover panel on the lathe bed longeron alternately and have guide groove in addition, the 3rd, the directive wheel in the guiding wheels, the 4th, be sleeved on the enforcement plate that has locking hole on the lathe bed crossbeam, the 5th, have guide groove the bed base plate, 6a and 6b are the spring electromagnet group, the 7th, be seated in the wind spring in the lathe bed wind spring case, 8 is that an end is connected with wind spring, the drag-line that the other end is connected with overcanopy carrier bar head end joint.

Shown in Figure 5 is the lathe bed parts, and 9 is preceding supports on it; The 10th, longeron; The 11st, back brace; The 12nd, the wind spring case; The 13rd, the base plate connecting plate; The 14th, the guiding wheel carrier; The 15th, the electromagnet support plate; The 16th, end plate; The 17th, crossbeam; The 18th, bolt hole.

Shown in Figure 6ly lean on before being, 19 is preceding by body on it; The 20th, guide groove; The 21st, locking hole.

Shown in Figure 7 is backstop, and 22 is backstop bodies on it; The 23rd, guide groove; The 24th, on turn over backstop; The 25th, spring; The 26th, locking hole; The 27th, the button pearl; The 28th, the locking card.

Shown in Figure 8 is the overcanopy carrier bar, and 29 is bodies on it; The 30th, end connector; The 31st, the head end joint; The 32nd, fastener set; The 33rd, open handle; The 34th, the guide head group; 35 is that the end other end that is connected with overcanopy carrier bar end connector is the drag-line in positioning and locking hole.

Shown in Figure 9 is 1 turnover panel.

Shown in Figure 10 is 2 guide plates, and 36 is guide grooves on it.

Shown in Figure 11 is the guiding wheels, and 37 is guiding wheel carriers on it; The 3rd, directive wheel; The 38th, spring; The 39th, the lock rope; 40 is ends with lock rope in the guiding wheels, and the other end that is connected is the drag-line in positioning and locking hole.

Shown in Figure 12 is 4 enforcement plates, and 41 is locking holes on it.

Shown in Figure 13 is 5 base plates, and 42 is guide grooves on it.

The spring electromagnet group, plane rotation spring, drag-line etc. are standard components on sale on the market.

Sequence of movement of the present utility model: under normal circumstances, insert in the positioning and locking hole of drag-line 35 after the iron core of electromagnet 6a and 6b inserts in the head of a bed and tailstock two locking holes of implementing plates 4 respectively again and the locking hole of drag-line 40 interior and lock.This moment, the whole bed body was in daily normal condition, any variation can not take place because of the action of the limited dynamics of bed staff, when earthquake takes place, at this moment can resilience because of the spring that is compressed in outage electromagnet group 6a and the 6b, screen resilience can be promptly with the iron core of electromagnet from drag-line 35, drag-line 40 with implement to retract in the positioning and locking hole of plate 4.The iron core of the electromagnet 6b of tailstock also can be from the other end to eject the kayser that is locked in the pearl from button after turning back normotopia under the effect of spring force tight with the backstop of turning over the backstop.So two guide wheels of guide wheel group are shot out guide plate 2 is strutted, the overcanopy carrier bar D that volume is put under bed side and bed can promptly move, on bed surface the triangle frame be put up soon by the guide groove of drag-line 8 at the pulling lower edge of wind spring 7 guide plate 2 and the preceding B of leaning on and backstop C and base plate 5.Implement plate 4 because of the support of the iron core that lost electromagnet 6 after upset downwards, also turn over down so cause turnover panel 1, and with 5 fastenings of bed base plate, two end end plates at this moment, both sides turnover panel and bed base plate be firm basin of composition under bed surface automatically.Also fallen by the wooden bed frame strung with crisscross coir ropes or the bed board of turnover panel 1 support, fall on the position safer in the bed, so the whole bed body is completed into for the lifesaving system that the protection bed staff avoids the earthquake disaster Automatic Combined to become from original position.

The advantage that the utility model is lifesaving bed: 1, mechanism is succinct, agile; 2, flat calamity combination is economical and practical.

Lifesaving bed is a kind of danger device of separating in the danger and disaster of saving lives, its selection must be strict: the required tubing of all lathe beds shown in Figure 5 all should be selected seamless manganese steel pipe for use, the required sheet material of all overcanopy carrier bars shown in Figure 8 should be selected the low-alloy quality steel plate for use, other sheet material can be selected quality structure steel plate more than No. 30 for use, all shown in Figure 6 preceding by selecting high-strength cast iron for use with backstop shown in Figure 7, wind spring should be selected the high-quality spring steel for use.

Processing and fabricating must be meticulous: blanking and parts assembling must have mould.Base plate, guide plate, preceding leaning on, the guide groove in the backstop all should meet the requirement of associated form and position tolerance.

The necessary science of check is comprehensive, except that material, processing, assembling must have associated science check, the more important thing is also and must lifesaving bed integral body be carried out the sensitivity response check of strict science and be born heavy load impact check.

Because the utility model is lifesaving bed, design science, selection strictness, make meticulous, check comprehensively, so it has minimum effective prevention is the good effect in 50 years the operating period, arbitrary moment in bed earthquake taking place any one evening, the people that reach in the time in 50 years, lifesaving bedly can both actively implement lifesaving effectively.But have 2 palpuses to emphatically point out: the first, lifesaving bed can only the use once, allly stand lifesaving bed can not the re-using that earthquake was hit.The second, must carry out annual check system without the lifesaving bed of earthquake strike in the process of using, carry out annual test by manufacturing firm, the content of annual test is: 1. whole lifesaving bed form and position tolerance is checked off-limits should the adjustment; 2. the elastic force of wind spring is checked, should in time be changed when decaying to the degree that to change as discovery wind spring elastic force.
