Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As shown in Figure 1, a kind of rail promotes device, including crossbeam 1,1 both ends of crossbeam to be connected separately with symmetrical two groups
Side pawl 2, side pawl 2 are rotatably connected with crossbeam 1, and the opposite side end face of two groups of side pawls 2 is equipped with the hook portion 22 of protrusion, two groups of sides
The clip slot 3 with rail cooperation is formed under 2 closed configuration of pawl.The utility model is simple in structure, is less than rail level using rail waist
Feature and the intensity of itself make two groups of side pawls 2 grip rail when in use, and rail is embedded in clip slot 3, and hook portion 22 is caught in rail
Waist, can stable holding rail, simple and quick, two groups of side pawls 2 being arranged symmetrically coordinate rail when rail is clamped
Symmetrical structure, the uniform force of two groups of side pawls 2 keep clamping process more stable, improve entrapment.
As shown in Fig. 1~5, further, the middle part of crossbeam 1, which offers, promotes hole 13, promotes hole 13 to be equipped with promotion and connects
Extension bar 5 can connect various lifting means, such as hydraulic jack, lifting equipment, mechanical lever by promoting connecting rod 5, reinforce
The fitness for promoting device and miscellaneous equipment keeps its use environment wider more flexible.
In the present embodiment, it is screw rod to promote connecting rod 5, and promotion hole 13 is threaded hole, and screw rod is threadedly coupled with threaded hole,
The toolings such as other existing hydraulic pressure, machineries are corresponded to by screw rod and carry out promotion rail, to reach repair rail easily purpose.
Preferred in this embodiment, the thickness of crossbeam 1 is 55~65mm, when on side, the gripping of pawl 2 rail is promoted, is made
Crossbeam 1 has preferable bending resistance, and to promote hole 13 to provide deeper connection depth, it is made to connect with connecting rod 5 is promoted
It connects more stable.
As shown in figures 4-6, in the present embodiment, the middle part at the both ends of crossbeam 1 offers link slot 11, two groups of side pawls 2 respectively
It is respectively arranged in the link slot 11 at 1 both ends of crossbeam, makes the uniform force of 2 both sides of side pawl, simultaneously as side pawl 2 is mounted on crossbeam 1
