Abstract
The utility model relates to a backstop rail clamping device, which comprises two clamping boards, on which connecting holes are provided and grooves matching the I-beams of the rail are positioned on the inner bottom wall, connected with each other through bolts for clamping the I-beams of the rail; trapezoidal grooves are arranged near the groove on the top of the clamping boards; slippers, whose figure are trapezoidal, are arranged in the trapezoidal grooves near the groove on the top of the clamping boards and the top is attached closely on the top of the clamping board groove and the bottom is attached closely on the I-beam rail. The two clamping boards are connected with each other and arranged on the I-beam rail as oblique surface on the rail sides and if impacted by the wheel of a crane, the stressed situation of the rail clamping boards is that the force drives the slippers in the trapezoidal grooves to press on the oblique surfaces more closely for clawing on the rails.
Description
Technical field
The utility model belongs to mechanical equipment and prevents device.
Background technology
Rail clamping device generally is used on the hoisting crane electric flat carriage of rail operation Electric Traction, referring to Fig. 1 a, Fig. 1 b, it comprises two bottom plate 1a, 2a, its underpart inwall has groove 11a, the 21a that is complementary with track I-beam section 4a, cooperates folder to establish track I-beam section 4a by bolt 3a these two bottom plate 1a, 2a; Its effect is to prevent to cause hoisting crane in order because of maloperation brake failure and irresistible natural cause, the equipment personnel's that the electric flat carriage whisk causes injury, large-tonnage remote control driving is wherein also installed sub-dolly in addition and is used for the usefulness that the slag bag is tumbled on the monkey.Malfunctioning because of hydraulic efficiency pressure system, sub-dolly moves with dolly, is in runaway condition fully.In order to stop sub-dolly free motion.With rail clamping device dolly is stuck on the track, guarantee that remote control driving can normal operation in the handling process.We find in actual mechanical process, the rail clamping device of An Zhuaning in orbit, thing every rail clamping device on the one with serious positioning, not only can not stop sub-dolly location, along with the moving of car of driving, produce its own inertial power sub-dolly position is moved on the contrary, caused device damage.
Summary of the invention
The purpose of this utility model is to provide a kind of retaining rail clamping device, can effectively stop the running of hoisting crane.
For achieving the above object, the technical solution of the utility model is, the retaining rail clamping device, be arranged on the track I-beam section, it comprises, two bottom plates, and its top is provided with connecting bore, its underpart inwall has the groove that is complementary with the track I-beam section, cooperates folder to establish the track I-beam section by these two bottom plates of bolt; The nearly groove of described bottom plate upper edge has trapezoidal chute; Slide block is trapezium structure, is arranged at the nearly groove of described bottom plate upper edge and has in the trapezoidal chute, and its upper surface is against the trapezoidal chute of bottom plate upper edge, and the lower surface is against the track I-beam section.
Description of drawings
Fig. 1 a, Fig. 1 b are the scheme drawing of existing retaining rail clamping device;
Fig. 2 is the structural representation of the utility model one embodiment;
Fig. 3 a, Fig. 3 b are running condition scheme drawing of the present utility model;
The specific embodiment
Referring to Fig. 2, Fig. 3 a, Fig. 3 b, retaining rail clamping device of the present utility model, be arranged on the track I-beam section 5, it comprises, two bottom plates 1,2, its top is provided with connecting bore 13,23, and its underpart inwall has the groove 11,21 that is complementary with track I-beam section 5, cooperates folder to establish track I-beam section 5 by bolt 3 these two bottom plates 1,2; Described bottom plate 1,2, nearly groove 11,21 upper edges have trapezoidal chute 12,22; Slide block 4 is trapezium structure, is arranged at the nearly groove of described bottom plate 11,21 upper edges and has in the trapezoidal chute 12,22, and its upper surface 41 is against the trapezoidal chute of bottom plate 12,22 upper edges, and lower surface 42 is against track I-beam section 5.
Be fixed on the track I-beam section 5 rail edge inclined-planes of being taken in after two bottom plates 1,2 merge and be subjected to after the wheel rim bump of hoisting crane, rail clamping device is stressed be slide block 4 in the trapezoidal chute 12,22 stressed after, inclined-plane and slide block 4 jam-packeds, rail clamping device firmly is bonded on the track.
If the dismounting rail clamping device pulls down bolt and knocks the rail clamping device back lightly with hammer, the rail clamping device pine.
