Abstract
The utility model discloses a device for limiting a net frame by inserting pin rods in the lifting process. The device is characterized by comprising one or more pin rods, and two pin plates which are parallelly arranged and vertically fastened on the same side of a net frame bracket, wherein one or more pairs of corresponding through holes are formed in each of the two pin plates; the length of the pin rods is greater than the distance between the two pin plates; and one end of each pin rod is convexly inserted into the corresponding through hole of each of the two pin plates in the construction direction of the net frame. By the device for limiting the net frame by inserting the pin rods in the lifting process, the net frame can be temporarily placed in the lifting process, and force borne by an upper steel strand can be reduced; and the device has the characteristics of simple structure and high safety and is convenient to construct.
Description
Technical field
The utility model relates to a kind of stopping means, espespecially a kind of lifting latch stopping means.
Background technology
In the lifting process for space truss structure, unavoidably can be because a variety of causes need to suspend the lifting of space truss structure, and space truss structure temporarily is held in midair, longer such as the required time of shelving, the steel strand that space truss structure top promotes just can be in stressed tension for a long time, thereby cause easily the damage of steel strand, promote operation for the rack framework and bring huge potential safety hazard, lack at present a kind of stopping means that can lie over and reduce at lifting process the negative power of upper steel twisted wire to space truss structure.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and provide a kind of lifting latch stopping means, realize a kind of stopping means that can lie over and reduce at lifting process the negative power of upper steel twisted wire to space truss structure, had simple in structure, safe, the easily characteristics of constructing.
The technical scheme that realizes above-mentioned purpose is:
A kind of lifting latch stopping means of the present utility model, comprise one or a plurality of pin rods be arranged in parallel with two and the vertical pin plate that is anchored on a rack support same side, described two pin plates offer one or plural number to the through hole of correspondence, the length of described pin rod is greater than the distance between two pin plates, and described pin rod one end is inserted in the corresponding through hole of described two pin plates projectedly to the Construction of The Grids direction.
Above-mentioned pin rod level.
The utility model has been owing to adopted above technical scheme, makes it have following beneficial effect to be:
Because being used of pin plate and pin rod realized a kind of stopping means that can lie over and reduce at lifting process the negative power of upper steel twisted wire to space truss structure, has simple in structure, safe, the easily characteristics of constructing.
Description of drawings
Fig. 1 is the structural representation of the utility model when promoting the latch stopping means and not plugging pin rod;
Fig. 2 is the structural representation of the utility model when promoting the latch stopping means and plugging pin rod.
The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
See also Fig. 2, a kind of lifting latch stopping means of the present utility model, comprise one or a plurality of pin rods 1 be arranged in parallel with two and the vertical pin plate 3 that is anchored on a rack support 2 same sides, two pin plates 3 offer one or plural number to the through hole 31 of correspondence, the length of pin rod 1 is greater than the distance between two pin plates 3, and pin rod 1 one ends to the Construction of The Grids direction projectedly level be inserted in the corresponding through hole 31 of two pin plates 3.
See also Fig. 1, when not using the utility model, pin rod 1 is detached between pin plate 3, this timer can not affect the normal hoisting of outside rack, brings any obstruction can for the lifting of outside rack.
Outside rack is carried out when spacing by the utility model at needs, at first outside rack is risen to the height that device is installed, then pin rod 1 is flatly inserted between two pin plates 3, one end of pin rod 1 protrudes to the Construction of The Grids direction, this moment, the jag of pin rod 1 was inserted in outside rack below, can suitably descend outside rack so that the rack bottom contacts with pin rod 1, and rack is set up on the pin rod 1.This device can be used in combination at a plurality of rack supports 2.
Because being used of pin plate 3 and pin rod 1 realized a kind of stopping means that can lie over and reduce at lifting process the negative power of upper steel twisted wire to space truss structure, has simple in structure, safe, the easily characteristics of constructing.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not consist of restriction of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
Claims (2)
1. one kind promotes the latch stopping means, it is characterized in that, comprise one or a plurality of pin rods be arranged in parallel with two and the vertical pin plate that is anchored on a rack support same side, described two pin plates offer one or plural number to the through hole of correspondence, the length of described pin rod is greater than the distance between two pin plates, and described pin rod one end is inserted in the corresponding through hole of described two pin plates projectedly to the Construction of The Grids direction.
2. lifting latch stopping means as claimed in claim 1 is characterized in that: described pin rod level.
