Fig. 3 is the partial enlarged view in Fig. 1 at B；

In above-mentioned attached drawing, the corresponding component names of appended drawing reference are as follows:

1- ladder, 2- stepboard, 3- platform, 4- pillar, 5- drawstring, 6- handrail, 7- limiting slot, 8- fixed frame, 9- weight Object places pocket, 10- fixed pulley, 11- sliding sleeve, 12- ball, the laborsaving handwheel of 13-.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing:

In conjunction with shown in Fig. 1, Fig. 2 and Fig. 3, the utility model includes inclined ladder 1, is sequentially fixed on the ladder 1 Several stepboards 2, the platform 3 that 1 upper and lower ends of ladder are set, the arm-rest frame being fixedly connected on ladder 1；

Arm-rest frame includes two pillars 4 and the handrail 6 that is fixedly connected between two pillars 4, and two pillars 4 are distinguished Vertical with the upper and lower ends of ladder 1 to be fixedly connected, the tilt angle of handrail 6 is identical as the tilt angle of ladder 1；

Weight conveying device is installed, which can be along the inclined direction of ladder 1 on the outside of arm-rest frame Convey weight；Here it is referred on the outside of arm-rest frame away from the side of stepboard 2.

Weight conveying device includes that two fixed pulleys 10, drawstring 5, weight place pocket 9, sliding sleeve 11 and fixed frame 8, and two Fixed pulley 10 is separately mounted on two pillars 4, and 11 sets of sliding sleeve can slide in handrail 6 and along bar length direction, sliding sleeve 11 It is not able to rotate in handrail 6, weight is placed pocket 9 and is fixedly connected on sliding sleeve 11 by fixed frame 8, and there are two living for the tool of drawstring 5 Moved end is both connected on fixed frame 8 after two movable end bypasses two fixed pulleys 10 respectively, in high-order fixed pulley 10 Axis be fixedly connected with laborsaving handwheel 13.

The working principle of the utility model is as follows:

Use condition is: the weight that construction personnel itself can move, but comparatively laborious, and such case makes It is too high with the cost of loop wheel machine, in particular, loop wheel machine is difficult to for weight to be hung to there, and weight category at the dead angle of some scaffolds When in the range of it can move, be most suitable for using, in addition, manpower is inadequate, a people alone carrying heavy goods when, be also applicable in very much.

For construction personnel in the lower end platform 3 of ladder, it is very painstaking to upper end platform 3 that carrying heavy goods walk ladder, at this point, can Weight is placed on weight to place in pocket 9, then oneself easily reaches the upper end platform 3 of ladder in the case where not bearing a heavy burden, so After hold laborsaving handwheel 13 and rotate high-order fixed pulley 10, the weight equipped with weight is placed by pocket 9 by drawstring 5 and is pulled to close to upper end Fixed pulley 10, is then blocked that (10 device of fixed pulley generally has wheel brake apparatus, and under normal circumstances, not having to will by the position of platform 3 Fixed pulley 10, which blocks, can also take out weight), weight is placed in pocket 9 from weight and is moved out, then discharges fixed pulley 10, To use next time.

In the present embodiment, 2 place side of stepboard is referred on the inside of arm-rest frame, is convenient for holding laborsaving handwheel 13 simultaneously in this way Rotation operation is carried out, to drive pulley rotation.

In the present embodiment, the diameter of laborsaving handwheel 13 is at least 2.5 times of the diameter of fixed pulley 10.

In the present embodiment, handrail 6 has two, is respectively provided in every handrail 6 there are two sliding sleeve 11, fixed frame 8 is same When be fixedly connected with all sliding sleeves 11, structure design is conducive to so that the structural stability of entire weight conveying device is higher Steady conveying weight.

In the present embodiment, handrail 6 is provided with limiting slot 7 along bar length direction, and 11 inner wall of sliding sleeve is installed with rotatable Ball 12, ball 12 are stuck in limiting slot 7 simultaneously, and can be rolled along limiting slot 7, and sliding sleeve 11 is supported on handrail by ball 12 On bar 6.The design of ball 12 and limiting slot 7, can not only anti-anti-skid sheath 11 rotated in handrail 6, and make sliding sleeve 11 can more smoothly slide in handrail 6.

According to above embodiment, the utility model can be realized well.It is worth noting that being set based on above structure Under the premise of meter, to solve same technical problem, even if made on the utility model it is some without substantive change or Polishing, the essence of used technical solution is still as the utility model, therefore it should also be as the protection in the utility model In range.
