Abstract
The utility model relates to the technical field of bridge crane equipment, and particularly relates to a concrete beam of a bridge crane track, which is capable of increasing the bearing capacity, the deformation resistance strength and the impaction force. The concrete beam comprises a track, a pressing plate, a concrete beam body, a concrete leveling layer, a reinforcing mesh, a resilient sleeper-bearing and a track bolt. According to the concrete beam, the reinforcing mesh is laid in the concrete leveling layer, the thickness of the concrete leveling layer is set to be 80-120mm, the strength grade is C40, the bearing capacity and the deformation resistance strengths of bending resistance and torsion resistance of the concrete beam body are enhanced, and the compression strength of a bearing surface is improved; the resilient sleeper-bearing is additionally arranged between the track and the concrete leveling layer, the strength of the concrete beam body bearing an impaction load is enhanced, the track deformation caused by deformation of the concrete beam body, track trapping of a wheel of a cart, and other accidents are reduced, the potential safety hazards are reduced, the service life of the bridge crane is prolonged, the maintenance cost is saved, and the production efficiency is increased.
Description
Technical field
The utility model relates to crane in bridge type equipment technical field, specifically a kind of crane in bridge type Gui Dao Quan beam that can strengthen bearing capacity, resistance to deformation intensity, impulsive force.
Background technology
It is 28.5 ~ 31.5m that general heavy industry enterprise adopts span more, and lifting altitude is 26m, grab bucket volume 3m
3, the twin beam overhead bridge crane that lifting weight is 10 tons, carries out turning batch mixing to ore materials.Impact due to operation field environment, twin beam overhead bridge crane in use for some time, easily there is the crane track distortion causing Yin the body distortion of Quan beam, the phenomenons such as the wearing and tearing of track liner come off, and track bolt of rear end plate is loosening, cause cart wheel card rail, the fracture of cart concrete beam, overhead traveling crane Frequent Troubles, has a strong impact on normal operations such as unloading ,Pei ore deposit, ore deposit and batch mixing, brings great potential safety hazard to production scene and operating personnel.
Utility model content
The purpose of this utility model is to provide a kind of crane in bridge type Gui Dao Quan beam, to solve crane in bridge type, easily occurs the track deformation causing Yin the body distortion of Quan beam, and the wearing and tearing of track liner come off, the problem that track bolt of rear end plate is loosening.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A crane in bridge type Gui Dao Quan beam, it comprises track, pressing plate, Quan beam body, concrete leveling layer, track bolt, and described concrete leveling layer laid inside has mattress, and the top of described concrete leveling layer is laid with resilient sleeper-bearing.
As further improvement of the utility model, the strength grade of described concrete leveling layer is C40, and thickness is 80 ~ 120mm.
As of the present utility model, further improve, the thickness of described resilient sleeper-bearing is 10 ~ 14mm.
The utility model is laid mattress in described concrete leveling layer, the thickness of concrete leveling layer is set to 80 ~ 120mm, and strength grade is C40, the weight capacity of Zeng Jia Quan beam body, bending resistance, the resistance to deformation intensity such as antitorque, increased the compressive resistance of weight-bearing surface; In the middle of track and concrete leveling layer, set up resilient sleeper-bearing, strengthen the withstand shocks intensity of load of Quan beam body, reduced the track deformation causing because of the body distortion of concrete beam, the accidents such as cart wheel card rail, reduced potential safety hazard, extend the service life of crane in bridge type, saved service expenditure, improved production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure 1, track, 2, nut, 3, spring washer, 4, upper flat gasket, 5, pressing plate, 6, resilient sleeper-bearing, 7, mattress, 8, concrete leveling layer, 9, concrete beam body, 10, lower flat gasket, 11, track bolt.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of crane in bridge type Gui Dao Quan beam as shown in Figure 1, it comprises track 1, pressing plate 5, Quan beam bodies 9, concrete leveling layer 8, track bolt 11, and concrete leveling layer 8 laid inside have mattress 7, and the top of concrete leveling layer 8 is laid with resilient sleeper-bearing 6.
The strength grade of concrete leveling layer 8 is C40, and thickness is 100mm.
The thickness of resilient sleeper-bearing 6 is 12mm.
Work progress of the present utility model and requirement:
The installation deviation that should check on request concrete beam body 9 before 8 construction of concrete leveling layer, the installation deviation of concrete beam body 9 must meet designing requirement, as undesirable, should adjust concrete beam body 9.According to the actual measurement absolute altitude of 9 of concrete beam bodies, determine a suitable concrete leveling layer 8 end face elevation control, installation form then, casting concrete.The necessary levelling press polish of end face of concrete leveling layer 8, must not have stone to expose and uneven phenomenon, does not allow to adopt the method levelling of the mortar that separately lays cement on concrete leveling layer 8 surface.End face at concrete leveling layer 8 lays resilient sleeper-bearing 6, lays track 1 on it, track 1 play movement 5 ~ 10mm, and the track bolt 11 of trapped orbit 1 and pressing plate 5 must be firmly, and the deviation of cart gauge is≤10mm, planar smoothness≤5mm on track 1.Crane in bridge type is unloaded, heavy load demonstration run is steady, without card rail phenomenon.
Above-described is only preferred embodiment of the present utility model, does not limit to the utility model.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model, can also make other equivalent modifications and improvement, all can realize the purpose of this utility model, all should be considered as protection domain of the present utility model.
