Abstract
The utility model relates to a safety ladder for ascending a height. The safety ladder comprises a straight ladder composed of a pair of angle irons which are vertically and symmetrically arranged and a plurality of crosspieces which are arranged on the pair of angle irons in an equal interval mode, and a safety device which is engaged with the straight ladder in a dismountable and slip mode. One end of the safety device is extended into the front side interval between the two angle irons to make the safety device perpendicular to the straight ladder. When a person ascending a height stays on the straight ladder, the upper body of the body tips back corresponding to the straight ladder; the person ascending a height is held on by the straight ladder through the safety device and a safety belt. The utility model has safety action, handy and convenient use, available double protection and enhanced use safety.
Description
The utility model relates to the facility of ascending a height, particularly a kind of security personnel's ladder of ascending a height.
The outwork personnel of industries such as electric industry, post and telecommunications, broadcasting, building often use the facility of ascending a height to climb the facility that electric pole, iron tower etc. have vertical height, the facility of ascending a height of Shi Yonging had mobile stairway in the past, foot rest, climbers, be fixedly mounted on the tubular pin nail on the cement electric pole, and be fixedly mounted on pin nail on the iron tower etc.Higher when the cement electric pole height, voltage is not suitable for climbing with mobile stairway, foot rest or climbers more than 3.5 kilovolts the time, at this moment just needs to install tubular ascend a height pin nail or the iron tower pin nail of ascending a height, and alleviating staff's physical demands, conveniently climbs up and down.But tubular pin nail and iron tower pin nail exist shortcomings such as lacking safety, and the security insurance measure can not be provided.
The purpose of this utility model provides a kind of security personnel's ladder of ascending a height, and it uses light and handy convenient, has safety effect, has improved safety.
A kind of security personnel's ladder of ascending a height described in the utility model comprises a vertical ladder, it also comprise one with the vertical ladder protector of slip joint removably; Described vertical ladder comprises the angle bar that a pair of vertical symmetry is provided with, and all crosspieces relatively-stationary on a pair of angle bar, spaced set, crosspiece is horizontally through the symmetrical circular hole of a pair of angle bar, a wherein head process of crosspiece is for the lateral surface of one of them angle bar, outstanding one of crosspiece is staggered and prominent at a pair of angle bar both sides lateral surface, and vertical ladder is fixedlyed connected with electric pole or iron tower; Described protector comprises a body that is formed by vertical card point that is mutually the right angle and horizontal card body, one is fixedly mounted in the through hole of body corner, two ends protrude in the guideway of body two sides respectively, one is installed in rotation in the groove of card body by pin, one distal process is for the curved piece of groove, one is fixedly mounted on curved piece protrudes in bolster piece on groove one end, one is installed in rotation on the bolster piece, two ends protrude in the little axle sleeve of bolster piece two sides, and one be separately fixed on the groove of card body and the curved piece, can promote curved piece and on parts towards the spring of guideway, in addition, but but the card body away from an end of body corner on also have first dog hole of clasp joint insurance and second dog hole of clasp joint safety belt.
The utlity model has safety effect, it is lightly convenient to use, and duplicate protection can be provided, and has improved safety in utilization.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a kind of schematic appearance of the security personnel's ladder of ascending a height.
Fig. 2 is the protector structural representation of the above-mentioned security personnel's ladder of ascending a height.
Referring to Fig. 1 and Fig. 2, a kind of security personnel's ladder of ascending a height comprises a vertical ladder 1, and one and vertical ladder 1 protector 2 of slip joint removably.
Vertical ladder 1 comprises the angle bar 3 that a pair of vertical symmetry is provided with, and all crosspieces 4 relatively-stationary on a pair of angle bar, spaced set.Crosspiece 4 is horizontally through the symmetrical circular hole of a pair of angle bar 3, and a wherein head process of crosspiece 4 promptly protrudes in the lateral surface of the same side angle bar for the lateral surface 5 of one of them angle bar.Outstanding one of crosspiece 4 is staggered and prominent at a pair of angle bar 3 both sides lateral surfaces, so that the foot-operated outstanding crosspiece 4 of mountaineer is along vertical ladder 1 upstream or downstream easily.Vertical ladder 1 is fixedlyed connected with electric pole or iron tower.
Protector 2 comprises a body 13 that is formed by vertical card point 11 that is mutually the right angle and horizontal card body 12, one is fixedly mounted in the body 13 corner through holes, two ends protrude in the guideway 14 of body 13 two sides respectively, one is installed in rotation on 16 li of the grooves of card body 13 by pin 15, one distal process is for the curved piece 17 of groove 16, one is fixedly mounted on curved piece 17 protrudes in bolster piece 18 on groove 16 1 ends, one is installed in rotation on the bolster piece 18, two ends protrude in the little axle sleeve 19 of bolster piece 18 two sides, and one is separately fixed on the groove 16 of card body 12 and the curved piece 17, can promote curved piece 17 and upper-part thereof spring 20 towards guideway 14.In addition, but but card body 12 away from an end of body 13 corners on also have first dog hole 21 of clasp joint safety rope and second dog hole 22 of clasp joint safety belt.
One end of protector 2 extend between two angle bar 3 the front side at interval in, even point 11 of the card on the body 13 and guideway 14 enter in the vertical ladder 1 at interval by vertical ladder 1 front side, and make card body 12 on the body 13 perpendicular to vertical ladder 1.Because the effect of spring 20 makes guideway 14 be close to the front side inner surface of vertical ladder 1, and makes little axle sleeve 19 be close to the preceding side external surface of vertical ladder 1, thereby do the time spent in no external force, protector 2 can rest on the vertical ladder 1, and has external force to do the time spent, and 2 of protectors can slide along vertical ladder 1.One end hook of safety rope is connected on 21 li of first dog holes of protector 2, other end clasp joint on mountaineer's belt on one's body, thereby form the first heavily insurance.One end hook of safety belt is connected on 22 li of second dog holes of protector 2, other end clasp joint on mountaineer's belt on one's body, thereby form the second heavily insurance.
Usually, when the mountaineer stops on vertical ladder 1,1 layback of the relative vertical ladder of health upper body, vertical ladder 1 is held the mountaineer by protector 2 and restraining harness, and this moment, restraining harness equally with the horizontal card body 12 of protector 2 also was the level of state.When the mountaineer falls for various reasons, the mountaineer will spur the overhanging end of protector 2 by restraining harness and/or safety rope downwards, thereby make protector 2 enter as shown in Figure 1 state, at this moment, card point 11 on protector 2 bodies 13 will be shelved on the crosspiece 4 of vertical ladder 1, thereby make the mountaineer avoid further falling.
