Abstract
The utility model relates to a jacking falling-off prevention device of a self-elevation tower crane, which is characterized in that a pin hole is arranged between a jacking cross beam fixing block and a standard mast section support block; the opening of the pin hole is located at the external side of standard mast section support block; and a falling-off prevention pill roll can be inserted into the pin hole to connect the jacking cross beam fixing block and the standard mast section support block. The jacking falling-off prevention device can effectively prevent the jacking pin roll from sliding off from an arc groove of the standard mast section, thus eliminating danger and ensuring the safety of the jacking and lowering operations.
Description
Technical field
The utility model relates to self-raising tower crane, a kind of jacking anti-drop device that is applied in the self-raising tower crane of more specifically saying so.
Background technology
The jacking crossbeam of self-raising tower crane be with its jacking pin bearing in standard knot anchor plate arc groove, this arc groove is an open slot, partly rise or during the decline operation,, then can produce danger in jacking if take place to tumble the anchor plate opening arc groove of jacking bearing pin from standard knot.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of self-raising tower crane jacking anti-drop device is provided, partly rise or during the decline operation to avoid the self-raising tower crane jacking, tumble the anchor plate arc groove of jacking bearing pin on the jacking crossbeam from standard knot, thereby eliminate the danger that may bring thus.
The utility model technical solution problem adopts following technical scheme:
The constructional feature of the utility model self-raising tower crane jacking anti-drop device is between jacking crossbeam fixed block and standard knot anchor plate pin-and-hole to be set, the pin-and-hole aperture is positioned at the outside of standard knot anchor plate, can be inserted with the anticreep bearing pin that forms pin joint between jacking crossbeam fixed block and standard knot anchor plate in described pin-and-hole.
The utility model constructional feature also is: described anticreep bearing pin one end is a cylinder, and the other end is a cylindrical step.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model is to increase the pin-and-hole that the form of remaining silent is set between jacking crossbeam fixed block and standard knot anchor plate, during jacking, the anticreep bearing pin is inserted in the pin-and-hole to implement the reliable location between jacking crossbeam and the standard knot, can effectively avoid tumbling the anchor plate arc groove of jacking bearing pin from standard knot, eliminate danger, improve job security.
2, the utility model anti-drop device is simple in structure, easy to make, and under the cost that increases seldom, the safety in the time of but greatly improving self-raising tower crane jacking or decline should be widely promoted.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that the position concerns scheme drawing between the utility model jacking bearing pin and the anticreep bearing pin.
Number in the figure: 1 standard knot anchor plate, 2 anticreep bearing pins, 3 jacking crossbeam fixed blocks, 4 jacking bearing pins.
Below by the specific embodiment, the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment:
Referring to Fig. 1, Fig. 2, identical with prior art is that the jacking crossbeam is bearing in the arc groove of standard knot anchor plate 1 with its jacking bearing pin 4.In the present embodiment, between jacking crossbeam fixed block 3 and standard knot anchor plate 1, pin-and-hole is set, the pin-and-hole aperture is positioned at the outside of standard knot anchor plate 1, can be inserted with the anticreep bearing pin 2 that forms pin joint between jacking crossbeam fixed block 3 and standard knot anchor plate 1 in pin-and-hole.
In concrete the enforcement, as shown in Figure 1, on the outside end face of jacking crossbeam fixed block 3, bore the hole of a φ 15 dark 25, on the relevant position of standard knot anchor plate 1, bore the through hole of a φ 15, be equipped with anticreep bearing pin 2 and can be inserted in φ 15 holes.
When needs carry out self-raising tower crane jacking or decline operation, jacking bearing pin 4 is put into anchor plate arc groove, anticreep bearing pin 2 inserts in the hole of φ 15, to couple together tightly between jacking crossbeam and the standard knot by anticreep bearing pin 2, make it to form an integral body, anticreep bearing pin 2 can be extracted out from φ 15 holes after jacking or decline operation are finished.
In concrete the enforcement, the position of pin-and-hole and aperture can be convenient to dismounting again for wanting towards being can firmly be arranged on pin-and-hole with locking pin axle 2 not come off voluntarily.Such as, the pin-and-hole aperture is positioned at top or the place ahead of standard knot anchor plate.
Claims (2)
1, self-raising tower crane jacking anti-drop device, it is characterized in that between jacking crossbeam fixed block (3) and standard knot anchor plate (1), pin-and-hole being set, the pin-and-hole aperture is positioned at the outside of standard knot anchor plate (1), can be inserted with the anticreep bearing pin (2) that forms pin joint between jacking crossbeam fixed block (3) and standard knot anchor plate (1) in described pin-and-hole.
2. self-raising tower crane jacking anti-drop device according to claim 1 is characterized in that described anticreep bearing pin (2) one ends are a cylinder, and the other end is a cylindrical step.
