Abstract
The utility model discloses a lower slide track of a variable-amplitude bridge floor crane. The lower slide track of the variable-amplitude bridge floor crane comprises a bottom beam, a first longitudinal-moving assembly, a second longitudinal-moving assembly and an oil cylinder. The first longitudinal-moving assembly and the second longitudinal-moving assembly are located at two ends of the bottom beam respectively. One end of the oil cylinder is connected with an oil cylinder base, the other end of the oil cylinder is connected with one end of a connecting beam through a first hinge pin, and the other end of the connecting beam is connected with the first longitudinal-moving assembly. The oil cylinder base is connected with the bottom beam through a second hinge pin. A transverse-moving cushion block is arranged between the oil cylinder base and the bottom beam. An anchoring pre-tightening cushion block is arranged below the bottom beam. At least three first cushion blocks are arranged between the first longitudinal-moving assembly and the ground, and at least three first cushion blocks are arranged between the second longitudinal-moving assembly and the ground. According to the lower slide track of the variable-amplitude bridge floor crane, one cushion block is arranged below the lower slide track in pre-tightening of a back anchoring threaded rod and is taken out when a whole machine moves forwards; and one cushion block is arranged between the lower side track and the oil cylinder base when a transverse-moving device is used, the cushion block is taken out when the transverse-moving device is dismounted, and therefore smoothness in longitudinal and transverse moving of the variable-amplitude bridge floor crane is guaranteed.
Description
Technical field
The utility model relates to a kind of luffing bridge floor loop wheel machine glide path.
Background technology
Along with the continuous propelling of modernization construction, the various places that spread all over the country such as expressway, through street, new stride Jiang Daqiao, cross a river bridge, viaduct even bridge spanning the sea also constantly build up.These bridges use ready-made segmented bridge floor to carry out the scene usually and build assembling at present, have improved efficient and quality.In build at the scene of bridge, the bridge floor loop wheel machine large lifting equipment that is absolutely necessary, a section bridge section of can slinging is placed into assigned address and assembles.The vertical and horizontal of luffing bridge floor loop wheel machine move the main glide path that relies on the bottom, but because load weight is very big, after long-time the use, glide path can produce distortion, hinders vertical and horizontal and moves, and demands urgently improving.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to propose a kind of luffing bridge floor loop wheel machine glide path, by enforcement of the present utility model, guarantees that luffing bridge floor loop wheel machine vertical and horizontal move smooth and easy.
For reaching this purpose, the utility model by the following technical solutions:
A kind of luffing bridge floor loop wheel machine glide path comprises:
Bottom girder;
The first vertical shift assembly and the second vertical shift assembly lay respectively at described bottom girder two ends;
Oil cylinder, an end is connected with oil cylinder seat, and the other end is connected with an end of tie-beam by first bearing pin, and the other end of described tie-beam is connected with the described first vertical shift assembly;
Oil cylinder seat is connected with described bottom girder by second bearing pin;
Be provided with traversing cushion block between described oil cylinder seat and the described bottom girder;
Described bottom girder below is provided with anchoring pretension cushion block;
At least three first cushion blocks are set between the first vertical shift assembly and the ground, at least three second cushion blocks are set between the second vertical shift assembly and the ground.
Preferably, the cross fall between the described first vertical shift assembly and the second vertical shift assembly is 2%.
Preferably, the described first vertical shift assembly and the described second vertical shift assembly are parallel to each other.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
The utility model by cushion block is set when the anchorage screw pretension of back below glide path, takes out during the complete machine reach; Traverse Displacement Unit arranges cushion block when using between glide path and oil cylinder seat, take out when Traverse Displacement Unit is removed, and has guaranteed that luffing bridge floor loop wheel machine vertical and horizontal move smooth and easy.

The specific embodiment
The utility model embodiment 1 provides a kind of luffing bridge floor loop wheel machine glide path, as shown in Figure 1 to Figure 3, comprising: bottom girder 1; The first vertical shift assembly 2 and the second vertical shift assembly 3 lay respectively at described bottom girder 1 two ends, can be arranged in parallel; Oil cylinder 5, one ends are connected with oil cylinder seat 6, and the other end is connected with an end of tie-beam 4 by first bearing pin 7, and the other end of described tie-beam 4 is connected with the described first vertical shift assembly 2; Oil cylinder seat 6 is connected with described bottom girder 1 by second bearing pin 8; Be provided with traversing cushion block 12 between described tie-beam 4 and the described bottom girder 1; Be provided with anchoring pretension cushion block 12 between described bottom girder 1 and the ground; Arrange between the first vertical shift assembly 2 and the ground at least three second cushion blocks 10 are set between three first cushion block, 9, the second vertical shift assemblies 3 and the ground at least, making the cross fall between the first vertical shift assembly 2 and the second vertical shift assembly 3 is 2%.
In the course of work, anchoring pretension cushion block 11 pad when the anchorage screw pretension of back takes out during the complete machine reach below glide path; Traversing cushion block 12 pad when Traverse Displacement Unit uses takes out when Traverse Displacement Unit is removed between glide path and vertical shift oil cylinder seat 6.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
