Described transport coaster is placed on the one end in above-mentioned horizontal rail, for transporting precast beam to assigned address;
Described mobile crane is positioned at the side of abutment, transports coaster for being hung onto by precast beam;
Described hoist engine is fixedly mounted on the abutment of the other end in above-mentioned horizontal rail, for drawing the transport coaster being placed with precast beam;
Described jack is placed on the both sides of pinner on abutment, for precast beam jack-up extraction out is transported coaster, is being transferred on pinner by precast beam.
Described cushion block is upper and lower double-layer structure, and lower floor is sleeper, and upper strata is steel plate.
Described mobile crane lifting capacity is at below 50t.
The beneficial effects of the utility model are:
(1) the utility model make use of equilibrium principle fully, cushion block and pinner is made full use of as the slideway paying beam slab translation in advance in the whole installation process of precast beam, using hoist engine as the power set transporting coaster translation, precast beam is transported to assigned address, in the middle of whole process, mobile crane only transports coaster for being hung onto by precast beam, simple to operate, scope of activities is little, particularly reduces the scope of activities of arm; Effectively solve the inadequate problem in precast beam operation (safety) space, and this device can simple, the dismounting of on-site consolidation, convenient transport (transporting coaster, jack and hoist engine own wt lighter), cost is low;
(2) cushion block in the utility model is that sleeper adds the upper and lower double-layer structure of steel plate, and sleeper plays cushioning effect, and steel plate hardness is large, and transport coaster can be made to smoothly pass;
(3) the mobile crane lifting capacity in the utility model is at below 50t, and overall volume is little, convenient transport and operation, and cost is also low.

Detailed description of the invention
In order to better understand the utility model, below in conjunction with embodiment and accompanying drawing, the utility model is further illustrated.
A kind of for installing small bridge precast beam device, it mainly comprises transports coaster 2, hoist engine 5, jack 6, mobile crane 9 and cushion block;
As shown in Figure 3, for filling and leading up on abutment 7 between pinner 8 and pinner 8 groove, (described abutment 7 upper surface is equidistantly provided with row's pinner 8 to described cushion block, pinner 8 and abutment 7 are all that concreting is shaping), described cushion block and pinner 8 form a horizontal rail (a pair abutment 7 of precast beam 1 to be installed or all abutments 7 all should be provided with horizontal rail) jointly;
As shown in Figure 3, described transport coaster 2 is placed on one end in above-mentioned horizontal rail (a pair horizontal rail of precast beam 1 to be installed is all placed with and transports coaster 2), for transporting precast beam 1 to the assigned address pinner 8 of installation precast beam 1 place (namely refer to need directly over);
As shown in Figure 1, described mobile crane 9 is positioned at the side (mobile crane 9 is selected to lay place according to concrete landform, determines the position of transporting coaster 2 and hoist engine 5 again according to the position of mobile crane 9) of abutment 7, transports coaster 2 for being hung onto by precast beam 1;
