Abstract
The utility model discloses an improved structure for a platform rail of a tower crane. The platform rail is formed by connecting a plurality of rail components; the end parts of cross rods of any two adjacent rail components are connected through a sleeve; fastening pieces, which are cotter pins, are arranged on the sleeve, so as to fix the end parts of the cross rods in the sleeve; and the cotter pins penetrate the sleeve and pin holes at the end parts of the cross rods, so as to fix the sleeve with the cross rods. The utility model has the advantages that the regulation range of the connection structure is large; the processing is simple and convenient; the manufacturing cost is low; and as the cotter pins replace a bolt set, the cost is further saved, and the disassembly and the assembly are convenient and fast.
Description
Technical field
The utility model relates to tower crane.
Background technology
The platform fence is made up of a plurality of fence assemblies 1; Fence assembly 1 is made up of montant 11 and cross bar 12 splicings; Connection structure in the prior art between the fence assembly is as depicted in figs. 1 and 2, clamps with clamping plate 2 between the adjacent montant 11 of fence assembly 1, again with bolt 3 connections.It is limited that but clamping plate connect setting range, in practice, the excessive and phenomenon that can't connect of fence spacing often occurs, thus the potential safety hazard of causing; While clamping plate processed complex.
The utility model content
The utility model technical matters to be solved just provides a kind of tower crane platform fence and improves structure, and the connection structure between the fence assembly is simple, and is simultaneously safe and reliable.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: tower crane platform fence improves structure; Said platform fence is connected to form by some fence assemblies; It is characterized in that: the crossbar end of two adjacent fence assemblies is coupled together by sleeve pipe, and sleeve pipe is provided with fastener is fixed in the said sleeve pipe crossbar end.
Preferably, said fastener is a spring cotter, and said spring cotter passes the pin-and-hole of said sleeve pipe and crossbar end sleeve pipe and cross bar are fixed.
The utility model connection structure setting range is big, processes simple and conveniently, cheap for manufacturing cost, and it is secondary to replace bolt with spring cotter, has further practiced thrift cost, convenient to disassembly.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described:
Fig. 1 is the structural representation of existing platform fence;
Fig. 2 is the A-A cutaway view among Fig. 1;
Fig. 3 is the structural representation of the utility model platform fence;
Fig. 4 is an I place enlarged drawing among Fig. 3;
Fig. 5 is an II place enlarged drawing among Fig. 3.
The specific embodiment
Extremely shown in Figure 5 like Fig. 3; For the utility model tower crane platform fence improves structure; Said platform fence is connected to form by some fence assemblies 1, and cross bar 12 ends of two adjacent fence assemblies are coupled together by sleeve pipe 4, and sleeve pipe is provided with fastener is fixed in the said sleeve pipe crossbar end.Said fastener is a spring cotter 5, and said spring cotter passes the pin-and-hole of said sleeve pipe and crossbar end sleeve pipe and cross bar are fixed.
The left side fence assembly at first is installed, again sleeve pipe is installed on the fence assembly cross bar of left side, the right side fence assembly is installed then, utilize sleeve pipe that two fence assemblies are linked together, accomplish fixing at last with spring cotter.
