Abstract

The utility model discloses a novel bridge type crane runway clip which aims at solving the problem that the rim of a wheel and a clip bottom plate of the current bridge type crane runway clip are impacted directly so as to cause a weld joint to be easily torn. The novel bridge type crane runway clip comprises a bottom plate, a supporting plate, an arc-shaped steel plate and a fixing frame, wherein the arc-shaped steel plate made from spring steel is tangential with the bottom plate and the supporting plate which are vertically welded; the fixing frame is welded below the bottom plate; the bottom plate is fixedly arranged on a runway through bolts; the width of the contact surface between the bottom plate and a wheel is consistent with that of the tread surface of the wheel; and buffer bodies are arranged at the horizontal and the vertical surfaces of the contact surface between the arc-shaped steel plate and the tread surface of the wheel. When the wheel comes over, the rim of the wheel is not contacted with the bottom plate of the crane runway clip, and the tread surface of the wheel is directly contacted with the two buffer bodies of the runway clip, so that for the clip, the impact strength is greatly weakened, the wheel rim is not damaged, the rigid collision is avoided, and the parking effect is better.

Description

Novel traverse crane track clamp

Technical field

The utility model relates to a kind of traverse crane, relates in particular to a kind of novel traverse crane track clamp.

Background technology

In commercial production, traverse crane is used very extensive, and main being responsible for receives raw material, unit material loading, discharging, and product car-loading etc. are for serialization production is given security.Need owing to produce, the crane of whenever striding operation has 5～6, because the needs that unit is produced require two adjacent cranes to lean on very closely in operational process, about 5-15 rice distance, and running velocity can not be low excessively.In the crane maintenance process, for example change big wheel, when the overhauling projects such as track of energy disperser, welding breaking are installed, service personnel must stand on the track just can finish the maintenance task, like this, if adjacent crane is the operating personal carelessness when operation, very easily cause crane to bump against or directly collide the personnel of welded rails, cause the service personnel injures and deaths.

For ensureing the personal safety of service personnel, adopt the track clamp usually, its both sides that are stuck in the crane that needs maintenance are maybe needed the two ends of the track that welds, prevent the collision of adjacent crane and then the personal safety of assurance service personnel with rigid means.Because the original track clamp forms by the rigid material welding production, at work by stopping with the rigid collision of wheel, the infringement to wheel and car body is very big like this, causes the breakage of wheel rim and the damage of bearing and key easily; And wheel rim and clamp base plate directly collide, and impulsive force is very big, causes weld seam to be torn easily, and the accident that the track clamp is smashed once appearred in clamp damage etc. in the use.

The utility model content

The purpose of this utility model is to overcome the prior art defective, and a kind of novel traverse crane track clamp is provided.

The technical solution of the utility model is achieved in that novel traverse crane track clamp, mainly form by base plate, stay bearing plate, curved plate, fixed mount, curved plate is tangent with the base plate and the stay bearing plate of vertical welding mutually, fixed mount is welded on floor below, by bolt that base plate is fixing in orbit, it is, the width of described base plate and wheel contact surface and the width of wheel tread are consistent, and is equipped with buffer body at curved plate and wheel tread phase-contact surface.

Further, described buffer body is respectively pacified one at the level and the vertical surface of curved plate.

Further, the welding of described curved plate bottom surface and base plate, and facade can about movable.

Further, described curved plate is made by spring steel.

The base plate of the utility model track clamp narrows down with comparing originally, its width with the width of wheel contact surface and wheel tread is consistent, when cartwheel roll is come, the wheel rim of wheel does not contact with the base plate of track clamp, but two block buffering body direct contacts of the tread of wheel and track clamp, buffer body and spring steel produce elastic deformation simultaneously when being subjected to wheel impacts, and produce the friction moment that stops wheel revolutions, so not only weakened impact greatly, can not produce infringement to wheel rim, avoided the rigidity collision, and the parking better effects if.

Among the figure, the 1-wheel; The 2-buffer body; The 4-base plate; The 5-curved plate; The 6-stay bearing plate; The 7-gusset; The 8-bolt; The 9-track; The 10-fixed mount.

The specific embodiment

Be further described below in conjunction with accompanying drawing:

As shown in the figure, novel traverse crane track clamp, mainly by base plate 4, stay bearing plate 6, curved plate 5, fixed mount 10 is formed, base plate 5 and stay bearing plate 6 are vertically welded in together, and welding gusset 7 is fixed strengthening, curved plate 5 bottom surfaces and base plate 4 welding, and facade can about movable, in order to damping, fixed mount 10 is welded on base plate 4 belows, by bolt 8 base plate 4 is fixed on the track 9, the width of described base plate 4 and wheel contact surface and the width of wheel 1 tread are consistent, and are equipped with rubber-buffer 2 at curved plate 5 and wheel 1 tread phase-contact surface, and described buffer body 2 is respectively pacified one at the level and the vertical surface of curved plate 5, be fixed on the curved plate 5 by screw, described curved plate 5 is made by spring steel.

In maintenance crane process, track clamp level is placed on the both sides of maintenance crane and keeps certain safety distance, and make the arcwall face of clamp relative with operating crane, then bolt of rear end plate 8 is tightened, clamp just has been stuck on the track 9 tightly like this.The width of track clamp base plate 4 and wheel contact surface and the width of wheel 1 tread are consistent, increased by two block buffering bodies 2, make common curved plate 5 with spring steel simultaneously, when adjacent crane during accidentally with the collision of track clamp, the wheel rim of wheel 1 does not contact with the track clamp, but the tread of wheel 1 contacts with buffer body 2.When impacted by wheel 1, buffer body 2 and curved plate 5 produce elastic deformation simultaneously, and produce the friction moment that stops wheel revolutions, have so not only weakened impact greatly, and the parking better effects if.
