Abstract
The utility model discloses a steel hoisting grab which comprises a connecting piece, a threaded hole formed on the connecting piece, a driving rod matched with the threaded hole, a sleeve pipe rotatably arranged at the lower end of the driving rod, two lifting hooks arranged at two sides of the driving rod, and two connecting rods of which one ends are rotatably connected with the sleeve pipe by a first rotating shaft, wherein the upper ends of the two lifting hooks are respectively and rotatably connected with a corresponding side of the connecting piece, and the other ends of the two connecting rods are rotatably connected with the lifting hooks arranged at the corresponding sides. The driving rod is rotated by the user, so that the driving rod is rotated and slides top and bottom relative to the connecting piece, and the connecting rods arranged at two sides respectively drive the lifting hooks arranged at the corresponding sides to be unfolded or closed, and can be locked per se through the threaded connection between the driving rod and the connecting piece, and therefore, the steel hoisting grab is safer to use, and the personal safety of the user can be guaranteed.
Description
Technical field
The utility model relates to the lifting device technical field, relates in particular to a kind of steel lifting grab.
Background technology
Fast development along with national economy, the use of large-scale steel structure in major project is also more and more, but the lifting for the I-beam section that plays the main support effect is to use steel rope binding lifting basically, since I-shaped steel section by producer to construction need to repeatedly start shipment, lifting etc., all there is the problem with steel rope binding, dismounting in each time lifting, operation inconvenience, work efficiency is lower.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, provide a kind of can be to steel member Quick-clamped and the firm lifting component grab that gets loose fast.
For achieving the above object, the technical solution of the utility model has provided a kind of steel lifting grab, comprise attaching parts, be opened in the tapped bore on the described attaching parts, the drive spindle that matches with described tapped bore, rotation is arranged at the sleeve pipe of described drive spindle bottom, be arranged at two suspension hooks of described drive spindle both sides, two connecting rods that one end and described sleeve pipe rotate and are connected by the first rotating shaft, the upper end of two described suspension hooks rotates with the respective side of described attaching parts respectively and is connected, and the other end of two described connecting rods rotates with the described suspension hook of respective side and is connected.
Preferably, be provided with between described attaching parts and the described drive spindle and prevent that described drive spindle breaks away from the stop gear of described attaching parts.
Preferably, described stop gear comprises the limiting section that is fixedly installed on described drive spindle upper end, and described limiting section can be pressed in the upper surface of described attaching parts.
Preferably, described suspension hook lower surface is circular-arc gradual bill to suspension hook.
Advantage of the present utility model and beneficial effect are: user's rotation of drive rod, drive spindle rotationally simultaneously relative attaching parts slides up and down, driven respectively suspension hook expansion or the closure of respective side by the connecting rod of both sides, simultaneously by in that be threaded between drive spindle and the attaching parts can self-locking, use safelyr, ensured user's personal safety.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, attaching parts; 2, drive spindle; 3, suspension hook; 4, connecting rod; 5, sleeve pipe; 6, limiting section.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of steel lifting grab, comprise attaching parts 1, be opened in the tapped bore on the described attaching parts 1, the drive spindle 2 that matches with described tapped bore, rotation is arranged at the sleeve pipe 5 of described drive spindle 2 bottoms, be arranged at two suspension hooks 3 of described drive spindle 2 both sides, two connecting rods 4 that one end and described sleeve pipe 5 rotate and are connected by the first rotating shaft, the upper end of two described suspension hooks 3 rotates with the respective side of described attaching parts 1 respectively and is connected, and the other end of two described connecting rods 4 rotates with the described suspension hook 3 of respective side and is connected.
As shown in Figure 1, be provided with the stop gear that prevents the described attaching parts 1 of described drive spindle 2 disengagings between described attaching parts 1 and the described drive spindle 2.
As shown in Figure 1, described stop gear comprises the limiting section 6 that is fixedly installed on described drive spindle 2 upper ends, and described limiting section 6 can be pressed in the upper surface of described attaching parts 1.Limiting section 6 also plays the effect of operating handle in addition, and the user operates drive spindle 2 rotating relative to attaching parts 1 by gripping limiting section 6.
As shown in Figure 1, described suspension hook 3 lower surfaces are circular-arc gradual bill to suspension hook 3.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
