Background technology

At present, engineering machinery supporting safe protective railing, use welding integral formula structure (shown in Fig. 4,5,6) usually.The welding integral formula guard rail of prior art adds column 1 by three layers of cross bar 2 and constitutes, and column lower end is aided with junction plate 3.Column is welded tube or shaped steel, and cross bar and column adopt and intersect the segmentation welding manner, that is: cross bar 2-1 in upper strata is a monolithic, and middle level cross bar 2-2 and the cross bar 2-3 of lower floor are segmented.During on-the-spot the installation, junction plate 3 and column 1 are welded on equipment or the building.Adopt the shortcoming of the welding integral formula railing existence of prior art: 1, the overall volume of railing is big, and transportation is inconvenient, the cost of transportation height.2, manufacturing process's complexity of railing, standardization level is low, is unfavorable for producing in batches, the manufacturing cost height, the manufacturing cycle is long.3, on-the-spot installation hoisting complexity, and installation cost height.

The utility model content

The purpose of this utility model is to overcome the weak point that prior art exists, and a kind of security protection activity railing is provided, and solves big, the transportation inconvenience of welding integral formula railing volume, manufacturing process complexity, the problem that cost is high.

The utility model is achieved through the following technical solutions:

A kind of security protection activity railing, comprise: three layers of cross bar, support the column of three layers of cross bar and be fixedly coupled plate with equipment, it is characterized in that: described column is pipe and is divided into three sections: column epimere, column stage casing, column hypomere, the top of described column epimere and upper tube joint are welded, be welded with the central tube joint between described column epimere and the described column stage casing, be welded with the lower tube joint between described column stage casing and the described column hypomere; Described upper tube joint, central tube joint, lower tube joint are horizontal bipass joint, and the through hole center line of three unions is parallel; Described three layers of cross bar are pipe, and the upper strata cross bar penetrates described upper tube joint, and the middle level cross bar penetrates described central tube joint, and lower floor's cross bar penetrates described lower tube joint; The lower end of described column hypomere is connected with junction plate.

The pipe both sides that the lower end of described column hypomere and junction plate join are the plane.

The caliber of described upper strata cross bar is big than the caliber of middle level cross bar and lower floor's cross bar, and the through hole internal diameter of the corresponding described upper tube joint that is attached thereto is also big.

Described upper tube joint, central tube joint, lower tube joint are spheroidal, and the two ends of central through hole are the plane.

Described upper tube joint, central tube joint, lower tube joint are processed with the screw that cooperates with trip bolt respectively.

The utility model compared with prior art has the following advantages and beneficial effect:

1, adopt cross bar and column separated structures, not only can reduce the railing shipping height, and volume comparatively disperses, thereby greatly reduce the cost of transportation of railing.

2, because of component all adopt shaped element, make making specialization, the standardization more of railing, significantly reduced the cost of manufacture of railing, increased the interchangeability of railing component simultaneously, shortened the manufacturing cycle.

3, the on-the-spot installation do not need lifting appliance, and with manually finishing, installation cost is low.

The utlity model has advantages such as volume is little, cost of transportation is low, manufacturing process is simple, installation cost is low.
