Meanwhile, due to the connection of pipe link and lower fixed friction block, being threaded by the contiguous block of the tie bolt hinged with pipe link and lower friction fixed block, effect platform can drive the rotation of tie bolt when rotating, tie bolt two ends and contiguous block turn tighter and tighter, and lower fixed friction block in tie bolt rotation process, can be caused to tighten up, what increase lower fixed friction block group holds friction force tightly.And the weight that job platform bears is larger, lower fixed friction block is received tighter, and the enclasping force that lower fixed friction block provides is larger, effectively ensure that the present invention can firmly, reliably be fixed on light pole.
As further preferred, described upper fixed friction block group comprises four pieces of upper fixed friction blocks, lower fixed friction block group also comprises four pieces of lower fixed friction block groups, and the interior contact surface of upper fixed friction block and lower fixed friction block all adopts high friction system rubber, has the tapering same with light pole inside them.Friction shoe after improvement can improve the fixing firmness of the present invention and light pole further, ensures the use safety of user.
Further again, the upper end of described pipe link is provided with hinged block, and the other end and the job platform of hinged block are hinged, wherein pipe link and hinged block are threaded connection, like this by rotary screwing thread, the length of fine setting pipe link, improves practicality of the present invention and alerting ability.

Being labeled as in accompanying drawing: 1-light pole, the upper fixed friction block of 2-, 3-limiting platform, 4-hinge hole, 5-job platform, fixed friction block under 6-, 7-contiguous block, 8-tapped bore, 9-tie bolt, 10-pipe link, 11-hinged block.
Embodiment: a kind of Streetlamp construction work platform, form as depicted in figs. 1 and 2, comprise the upper fixed friction block group and lower fixed friction block group that hold around light pole 1, upper fixed friction block group comprises the upper fixed friction block 2 linked together with rope of more than two pieces, the quantity of upper fixed friction block can be 2 pieces, 3 pieces, 4 pieces even more, but consider from holding fastness, stability and part degree of simplifying tightly, it is the most rational that upper fixed friction block group comprises 4 pieces of upper fixed friction blocks.As shown in Figure 3, the both sides of upper fixed friction block 2 are provided with limiting platform 3, hinge hole 4 is provided with above limiting platform 3, hinge hole 4 has a job platform 5 through chain connection, when job platform turns to horizontal surface, the bottom surface of job platform contacts with limiting platform, and limiting platform plays support, fixing effect to job platform, on every block, fixed friction block correspondence arranges 4 pieces of job platforms, and 4 pieces of job platforms form the complete scope of operation.The upper surface of described limiting platform is a dip plane, dip plane is to job platform lopsidedness, and the angle of dip plane is 15 degree, and arranging a dip plane is make job platform when forwarding horizontal surface to, also have the rotation space of downward 15 degree, be convenient to the adjustment of buffering and other parts.Described lower fixed friction block group comprises the lower fixed friction block 6 of more than two pieces, and the angle that the outside of lower fixed friction block 6 is provided with 2 pieces of contiguous blocks, 7,2 pieces of contiguous blocks is 90 degree, and therefore the homonymy contiguous block of adjacent lower fixed friction block is in parastate.As shown in Figure 4, contiguous block 7 is provided with tapped bore 8, and adjacent tapped bore 8 is connected by the threaded tie bolt 9 of tool, and tie bolt 9 is hinged with a pipe link 10, and upper end and the job platform 5 of pipe link 10 are articulated and connected.The same with the composition of upper fixed friction block group, described lower fixed friction block group also comprises four pieces of lower fixed friction blocks 6.And the interior contact surface of described upper fixed friction block 2 and lower fixed friction block 6 all adopts great friction coefficient rubber, the inner side of upper fixed friction block 2 and lower fixed friction block 6 has the tapering same with light pole.As shown in Figure 5, the top of described pipe link 10 is provided with hinged block 11, and the other end and the job platform 5 of hinged block 11 are articulated and connected; The end of described pipe link 10 is provided with outside thread, and the bottom of hinged block 11 is provided with negative thread, and pipe link 10 and hinged block 11, by screw thread fit, regulate the length of pipe link 10.
Principle of work: during installation, determine the fixed position of job platform on light pole, 4 upper fixed friction block steel ropes are held this attachment point of light pole, use hinge job platform, again by the hinge-point outside job platform and pipe link hinged, the lower end of pipe link and tie bolt carry out hinged, and the two ends of tie bolt screw with the contiguous block on lower fixed friction block and are connected, and complete the installation of first piece of job platform.Complete the installation of remaining three pieces of job platforms more successively, lower fixed friction block surrounds light pole through four tie bolts connections, and under the force of four pipe links, automatically light pole is held tightly, because tie bolt and contiguous block are screw thread fit, when operation flat top is larger, pipe link force is larger, the screw thread fit of tie bolt and contiguous block is tighter, make to receive tighter between adjacent lower fixed friction block, the enclasping force that lower fixed friction block group provides is larger, effectively ensure that the present invention can firmly, reliably be fixed on light pole.
