Description

Driving backstop device that can swiftly install

Technical Field

The utility model relates to a driving corollary equipment technical field, concretely relates to driving backstop device that can swiftly install.

Background

When the travelling crane needs to be overhauled or forbidden in the same cross-region, in order to prevent the travelling crane from running to the region, the travelling crane stop is frequently used. The domestic published technology of the traveling stopper patent has the following problems in the use process: when a driving large wheel collides with a driving stop when a driving runs, the stop is fastened by using bolts, when the stop generates a backward downward force, the stop has a backward movement tendency, the stop or the bolts can be pulled and deformed, the subsequent disassembly is very troublesome, the destructive disassembly is often finished, and the use rate of the stop is very low; (2) the stop is troublesome to manufacture and needs more materials; (3) in emergency and when temporary maintenance is needed and a stop is needed, the time for mounting and dismounting is long.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a driving backstop device that can swiftly install has solved current driving backstop device rate of utilization low, and installation, dismantlement spent time are longer, and the material of needs is more problem.

The technical scheme is as follows: the utility model relates to a driving backstop device that can swiftly install, including backstop base, arc and driving track, the perpendicular fixed mounting of arc is at the top surface middle part of backstop base, the width of backstop base narrows down along its length direction gradually, and the narrowest department of backstop base width is the same with driving track's width, and the narrowest department of backstop base width is located the homonymy with the cambered surface of arc, be equipped with the friction disc in the clearance between backstop base width and the driving track width, the friction disc narrows down along its length direction gradually, the dog is installed through the pivot in the widest department of backstop base width, the dog contacts with the friction disc.

Furthermore, a groove is formed in the top surface of the travelling crane rail, a protrusion corresponding to the groove is arranged on the bottom surface of the stop base, and the protrusion is matched with the groove.

Furthermore, the arc-shaped plate is also provided with a round hole.

Further, the stop block is of a trapezoidal structure.

Further, the length of backstop base is greater than the length of arc.

Compared with the prior art, the utility model discloses beneficial effect: the utility model discloses install when needing to forbid the line with striding the driving overhaul, can realize quick installation, dismantlement. Because the friction force is skillfully utilized for braking, the bolt or the stop can be prevented from being damaged by pulling during braking, and the service life of the stop device is greatly prolonged. The utility model discloses structural type simple manufacture, labour saving and time saving, required material is less, has saved the cost of manufacture.

Detailed Description

The invention will be further described with reference to the following figures and examples:

as shown in fig. 1 to 5, the utility model relates to a driving backstop device capable of being quickly installed, including backstop base 1, arc 2 and driving track 3, arc 2 is vertically and fixedly installed at the middle part of the top surface of backstop base 1, and the length of backstop base 1 is greater than the length of arc 2, the width of backstop base 1 narrows gradually along its length direction, the narrowest part of backstop base 1 width is the same as the width of driving track 3, the narrowest part of backstop base 1 width is located the same side with the cambered surface of arc 2, be equipped with friction disc 4 in the clearance between backstop base 1 width and driving track 3 width, friction disc 4 narrows gradually along its length direction, dog 5 is installed through the pivot at the widest part of backstop base 1 width, dog 5 is the trapezium structure, dog 5 contacts with friction disc 4; when the travelling wheels touch travelling stops, backward acting force is generated, and great friction force generated by the bottom surface of the stop base 1, the top surface of the travelling track 3 and the friction plate 4 is utilized to generate braking force so as to prevent the travelling crane from continuing to run and effectively play a role in stopping the travelling crane; the traveling crane stopping device is provided with devices such as a rib plate, the reliability and the safety of the traveling crane stopping device are ensured by increasing the size and the welding surface of the arc plate, and the traveling crane stopping device is very simple in manufacturing, mounting and dismounting processes and quick to use due to the fact that bolts are omitted;

a groove 6 is arranged on the top surface of the travelling crane rail 3, a bulge 7 corresponding to the groove 6 is arranged on the bottom surface of the stop base 1, and the bulge 7 is matched with the groove 6; the groove 6 on the travelling crane rail 3 is matched with the bulge 7 on the stop base 1, so that the travelling crane stop cannot incline, and the speed of stopping the travelling crane is increased; meanwhile, in order to ensure the usability of the travelling crane rail 3, when the travelling crane stopping device is not installed, the lug which is the same as the bulge 7 is placed in the groove 6, so that the normal use of the travelling crane rail 3 is ensured;

still be equipped with the round hole 8 on the arc 2, cancelled the tubular type handle, through opening round hole 8 on arc 2, reach the effect of handle, saved the material, and the material that needs the use reduces.

The utility model discloses install when needing to forbid the line with striding the driving overhaul, can realize quick installation, dismantlement. Because the friction force is skillfully utilized for braking, the bolt or the stop can be prevented from being damaged by pulling during braking, and the service life of the stop device is greatly prolonged.
