Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As shown in Figure 1 to Figure 3, jenny, comprises trolley base 1, column 2, arm 3, hanging apparatus 5; Described arm 3 is arranged on column 2; Described arm 3 is provided with at least one suspension bracket 4; Described hanging apparatus 5 is arranged on suspension bracket 4;

Described trolley base 1 comprises strut bar 11, fastener 12, stay bearing plate 13; Described strut bar 11 is connected to form trolley base framework by fastener 12; Described stay bearing plate 13 is arranged on trolley base framework; Described column 2 is vertically mounted on stay bearing plate 13; Roller 6 and adjustable load-bearing bearing 9 is provided with bottom described trolley base 1.

At employing jenny described in the utility model, in the process that midget plant is lifted: moved to by jenny on the fabricating yard that needs to carry out hanging device, then regulate the adjustable load-bearing bearing 9 bottom trolley base 1; Make the roller 6 bottom trolley base 1 depart from ground, trolley base 1 is supported by adjustable load-bearing bearing 9 completely.Then by the hanging apparatus 5 on arm 3, equipment is sling, then by manually slowly moving equipment, making equipment be displaced on relevant position, putting down equipment by hanging apparatus 5; Thus complete lifting.

Because described trolley base 1 is made up of strut bar 11, fastener 12, stay bearing plate 13 etc., therefore at construction site, the material of discarded building materials and scaffold can be adopted to make, can productive costs be effectively reduced.

Owing to being provided with roller 6 and adjustable load-bearing bearing 9 bottom described trolley base 1; Therefore adopting when lifting adjustable load-bearing bearing 9 to support whole jenny, avoiding roller 6 to be damaged, being supported by roller 6 pairs of jennies after lifting completes simultaneously, be convenient to the movement of jenny.

The trolley base 1 of jenny described in the utility model adopts strut bar 11, fastener 12, stay bearing plate 13 to be connected and to form in sum, therefore according to the trolley base 1 of the size combinations corresponding size in lifting place, can not be subject to the impact in lifting place; Structure is simple simultaneously, volume is little, lightweight, it is little to take up an area, move, dismantle, assemble and conveniently moving rapid, labour intensity is low, save labor, and can by the discarded fastener of construction site, the materials such as steel pipe make, and can dismantle after lifting construction completes, and are recycled by all parts; Can cost of manufacture be effectively reduced, reduce hoisting cost.

In order to make jenny arm 3 when lifting to rotate, thus make the midget plant by hanging can rotate certain displacement around column 2; Increase the lifting region of jenny.Further as shown in Figure 1, described jenny, also comprises bearing seat 8; Described arm 3 comprises hold-down arm 31, pull bar 32, rotating shaft 33; Described rotating shaft 33 two ends are arranged on column 2 by bearing seat 8; Described hold-down arm 31 one end is coupling end, and the other end is lifting end; Described coupling end is connected with rotating shaft 33, and lifting end extends trolley base 1; Described pull bar 32 one end is connected with rotating shaft 33, and the other end is connected with hold-down arm 31, and described pull bar 32, rotating shaft 33, hold-down arm 31 surround triangle; Described suspension bracket 4 is arranged on hold-down arm 31.

The lifting end of described hold-down arm 31 extends trolley base 1 and refers to that the projection of lifting end in trolley base 1 on vertical direction of described hold-down arm 31 extends to the position beyond trolley base 1.

Can by arranging rope on arm 3 in the process of lifting, when equipment lifts by the hanging apparatus 5 on arm 3, by pulling, the rope on arm makes the hold-down arm 31 of arm 3, pull bar 32 is followed rotating shaft 33 and rotated; Thus make the equipment by lifting rotate certain angle aloft.Thus increase the lifting region of jenny.

In order to avoid jenny is turned on one's side when the midget plant slinging heavier, further, described trolley base 1 is provided with counterweight 7; Described counterweight 7 is positioned at the side of column 2, and this side is positioned at the reversing sense that arm 3 points to.Main Function due to counterweight 7 prevents jenny from turning on one's side, and therefore counterweight 7 should be arranged on jenny and be subject to maximum rollover power.Described counterweight 7 is positioned at the side of column 2, and this side is positioned at the reversing sense that arm 3 points to.Make the equipment on the lifting end of counterweight 7 and arm 3 be positioned at the two ends of lever, thus avoid jenny to turn on one's side.

In order to adapt to different hoisting heights, be convenient to the installation of column 2, further, described column 2 adopts spliced simultaneously, and described column 2 is docked by least two sub-columns and formed, and described arm 3 is arranged on wherein on any one sub-column.Needing in the process that hoisting height is adjusted, only the sub-column being provided with arm 3 need be installed to the position of corresponding height in the splicing of column 2.

Promote dolly for the ease of staff, further, described trolley base 1 is provided with pushing hands railing 14.

Described roller 6 can adopt tight pulley or adopt cardan wheel, and because cardan wheel has turning function, therefore make the propelling movement of dolly convenient, preferred described roller 6 adopts cardan wheel.

The Main Function of described hanging apparatus 5 is elevated by the equipment lifted, and described hanging apparatus 5 can adopt various ways, and as adopted winch, in order to make structure reduce, reduce manufacturing cost preferred, described hanging apparatus 5 adopts electric block.
