Abstract
The utility model discloses a standard festival with half space, including fixing the cat ladder on to the brail in the standard festival, the left side or the right side of cat ladder are equipped with the footboard, and the footboard is trapezoidally, and welded fastening are on the main frame of adjacent side of standard festival respectively for two waists of trapezoidal pedal, and the footboard lies in the standard bottom of festival, and the one end of first protection horizontal pole is fixed and is gone up at the ladder frame of cat ladder, the other end is fixed on the standard festival frame with the cat ladder opposite side, and first protection horizontal pole lies in the middle part that the standard saved. Simple structure, footboard make things convenient for the staff to scramble the rest that stands when having tired out, stand comfortable on the cat ladder foot bar, safety, and the setting of first, second protection horizontal pole can prevent that the staff from falling in the space of the both sides of the center of standard festival and frame, and all -round conservation work personnel ensure staff's personal safety, and anti -skidding line has increased the frictional force on footboard surface, prevents that the surface from skidding, further promotes the security.
Description
Technical field
This utility model relates to derrick crane and manufactures installing area, is specifically related to a kind of standard knot being provided with half space.
Background technology
In recent years, along with the rapid growth of China's economic construction, capital construction scale constantly expands, particularly being on the increase of high-building construction, and the application of derrick crane is the most extensive.The standard knot of derrick crane is to determine tower crane height, the vitals of stability, operator climb to the driver's cabin interior manipulation tower crane at tower crane top by the cat ladder on standard knot, along with being continuously increased of depth of building, the height of tower crane also can follow increase, operator need standing in and have a rest on the treadle of cat ladder frequently during the tower crane of climbing up to tens of meters, it is generally pipe to climb comfortable treadle, stepping down in has a rest on treadle, and not only to trample face little but also easily skid, and there is the potential safety hazard fallen.
Summary of the invention
The utility model discloses a kind of standard knot being provided with half space, it is simple to operator have a rest, comfortableness and safety are high.
This utility model is achieved through the following technical solutions:
It is provided with the standard knot of half space, including the cat ladder being fixed on standard knot digonal link, left side or the right side of described cat ladder are provided with pedal, described pedal is trapezoidal, two waists of trapezoidal pedal are respectively welded on the main frame being fixed on standard knot adjacent side, described pedal is positioned at the bottom of standard knot, and one end of the first protection cross bar is fixed on the ladder of cat ladder, the other end is fixed on on the standard knot framework of cat ladder opposite side, and described first protection cross bar is positioned at the middle part of standard knot.
This utility model further improvement project is, two sides of the standard knot being connected with pedal are provided with the second protection cross bar, between the main chord being fixed on standard knot of described second protection cross bar.
This utility model further improvement project is, described second protection cross bar and the first protection cross bar are contour.
This utility model further improvement project is that the width of pedal is at least 25cm.
This utility model further improvement project is that the upper surface of described pedal is provided with anti-slip veins.
This utility model further improvement project is, the digonal link bottom the bottom surface of described pedal and standard knot is welded and fixed
Compared to the prior art this utility model has the advantage that
This utility model simple in construction; pedal facilitates staff to climb the when of having tired out to stand has a rest; relatively stand in comfortable on cat ladder treadle, safety; fall in the space of the both sides that the setting of first, second protection cross bar is prevented from the staff center from standard knot and framework; omnibearing protection staff, it is ensured that the personal safety of staff, anti-slip veins adds the frictional force of pedal surface; prevent slippery surface, promote safety further.
Accompanying drawing explanation
Fig. 1 is this utility model plan structure schematic diagram.
Fig. 2 be in Fig. 1 A to structural representation.
Detailed description of the invention
The standard knot being provided with half space as shown in Figure 1, 2, including the cat ladder 1 being fixed on standard knot digonal link 6, left side or the right side of described cat ladder 1 are provided with pedal 2, described pedal 2 is trapezoidal, two waists of trapezoidal pedal 2 are respectively welded on the main frame being fixed on standard knot adjacent side, described pedal 2 is positioned at the bottom of standard knot, one end of first protection cross bar 3 is fixed on the ladder of cat ladder 1, the other end is fixed on on the standard knot framework of cat ladder opposite side, and described first protection cross bar 3 is positioned at the middle part of standard knot.
In the present embodiment, two sides of the standard knot being connected with pedal 1 are provided with the second protection cross bar 4, and described second protection cross bar 4 is fixed between the main chord of standard knot；Second protection cross bar 4 is contour with the first protection cross bar 3；The width of pedal 1 is at least 25cm；The upper surface of pedal 1 is provided with anti-slip veins 5；Digonal link 6 bottom the bottom surface of pedal 2 and standard knot is welded and fixed.
