Technical field
The utility model relates to a kind of anti-device of overstepping the limit, and particularly a kind of C shape guide rail is with preventing the device of overstepping the limit.
Background technology
In fields such as electric power power transmission and transformation line shaft tower, power transformation framework, communication shaft tower and building, all be unable to do without ascend operation, in recent years, electric power development speed is very fast, requirement to the safety management level is more and more higher, the task of power grid construction and transformation is also more and more heavier, a large amount of constructions, service work task all relate to ascend operation, if there is not reliable fall arrest equipment, will cause huge potential safety hazard to the staff.
In order to prevent that fall arrest is provided with catching device and causes from the initial landing of specific C shape guide rail the damaging of staff, people have installed the anti-device of overstepping the limit on C shape guide rail.After the present anti-device of overstepping the limit is installed on the C shape guide rail, also need on fall arrest equipment, install a safety pin device additional and be used, increase the production cost of anti-fall equipment undoubtedly, strengthen the volume of anti-fall equipment, and inconvenience is carried, and makes troubles for work people's use.
Summary of the invention
At the deficiency that prior art exists, the utility model provides a kind of and has prevented catching device landing from the C shape guide rail, made things convenient for catching device installing/dismounting and C shape guide rail simple in structure with the anti-device of overstepping the limit.
For achieving the above object, the utility model provides following technical scheme: a kind of C shape guide rail is with preventing the device of overstepping the limit, include Connection Block, described Connection Block is provided with the bayonet lock that is articulated and connected with it, bayonet lock is along the fixed axis rotation that is fixed on the Connection Block, Connection Block is provided with the locating part spacing with bayonet lock, and bayonet lock is provided with return unit.
Connection Block is provided with the bayonet lock that is articulated and connected with it in this, and bayonet lock is along the fixed axis rotation that is fixed on the Connection Block, and Connection Block is provided with the locating part spacing with bayonet lock, and bayonet lock is provided with return unit.After being provided with like this, catching device is put into the process of C shape guide rail, can directly push bayonet lock aside, bayonet lock then can rotate along fixed axis; After catching device falls into C shape guide rail, bayonet lock can be got back to original position by the return unit that is provided with on it, slide in catching device and the C shape guide rail and when conflicting with bayonet lock, the locating part of being located on the Connection Block then can block bayonet lock, it can not be rotated, thereby guaranteed that catching device can be from the initiating terminal landing of C shape guide rail.
The utility model further is set to: described Connection Block has a base and two sides that are connected with the base, one of them side is provided with the extension edge of perpendicular setting, described bayonet lock is articulated on this extension edge by fixed axis, described locating part is the spacing block set a little more than bayonet lock that the Connection Block side is provided with, described bayonet lock is the inclined-plane towards an end of this spacing block set, and described return unit is the reduction torsion spring of being located between bayonet lock and the connecting bolt.
Connection Block has a base and two sides that are connected with the base in this.The purpose of She Zhiing is for Connection Block can being coated C shape guide rail, making the connection between it more compact like this; And a side of Connection Block is provided with the extension edge of perpendicular setting, and bayonet lock is articulated on this extension edge by fixed axis.Be provided with rational in infrastructure like this; Described locating part is the spacing block set a little more than bayonet lock that the Connection Block side is provided with, and described bayonet lock is the inclined-plane towards an end of this spacing block set, and return unit is the reduction torsion spring of being located between bayonet lock and the connecting bolt.Setting operation is convenient like this, and simple in structure.
The utility model further is set to: the base of described Connection Block is provided with and screw.
Base of Connection Block is provided with and screw in this.Be provided with like this and made things convenient for being connected between Connection Block and the C shape guide rail, it can be connected with C shape guide rail bolt by this screw.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the end view of the utility model embodiment;
Fig. 3 is the upward view of the utility model embodiment;
Fig. 4 be among the utility model embodiment with the structural representation of C shape track combination.
Embodiment
As the anti-device of overstepping the limit of Fig. 1, Fig. 2, Fig. 3, a kind of C shape guide rail shown in Figure 4, include Connection Block 1, described Connection Block 1 is installed on the initiating terminal of C shape guide rail 2, Connection Block 1 is provided with the bayonet lock 3 that is articulated and connected with it, bayonet lock 3 is along fixed axis 4 rotations, Connection Block 1 is provided with the locating part spacing with bayonet lock 3, and bayonet lock 3 is provided with return unit.
In the utility model embodiment, described Connection Block 1 has a base 11 and two sides 12 that are connected with base 11, one of them side 12 is provided with the extension edge 13 of perpendicular setting, here need to prove, it all is feasible on any one side 12 of Connection Block 1 extension edge 13 being set, in the utility model embodiment, because Connection Block 1 is a bending and molding, so extension edge 13 is wholely set with side 12, certainly, extension edge 13 also can be provided with separately, can be and side 12 welding or clampings, and this also belongs within the protection range of this patent; Described bayonet lock 3 is articulated on the extension edge 13 of Connection Block 1 by fixed axis 4; Certainly, also can directly bayonet lock 3 be located on the side 12 of Connection Block 1, the installation of inconvenient bayonet lock 3 just be set like this, so the utility model adopts the former; Described locating part is the spacing block set 14 a little more than bayonet lock 3 that Connection Block 1 side 12 is provided with, described bayonet lock 3 is inclined-plane 31 towards an end of this spacing block set 14, described return unit is the reduction torsion spring of being located between bayonet lock 3 and the fixed axis 45, being provided with like this is operation for convenience, in use, when catching device is inserted in the C shape guide rail 2, catching device at first can contact with the inclined-plane 31 of bayonet lock 3, stir bayonet lock 3, bayonet lock 3 is along fixed axis 4 rotation, until bayonet lock 3 revolve turn 90 degrees after, catching device just can be inserted in the C shape guide rail 2 smoothly, at this moment, bayonet lock 3 just can by and fixed axis 4 between reduction torsion spring 5 be returned to original position.If catching device landing backward, then can conflict, and bayonet lock can be conflicted with the spacing block set 14 on the Connection Block 1 for 3 this moments, thereby realization prevents that catching device can landing from C shape guide rail 2 with the other end on bayonet lock 3 relative its inclined-planes 31; As need catching device is taken out from C shape guide rail 2, then need upwards be mentioned it, bayonet lock 3 are manually revolved to turn 90 degrees again, just can smoothly catching device be taken out from C shape guide rail 2.
