Background
In the field of engineering, buildings are increasingly displaced. The manner of displacement is also varied. The walking method and the dragging method are common, and the two methods have advantages and disadvantages respectively.
The walking method has little influence on the existing traffic, can reduce the temporary structure engineering quantity, has relatively slow pushing speed, but has high intelligent degree and can automatically adjust the stress state of the structure. The walking method has more advantages, is suitable for the top pushing line type, can control the top pushing force in real time, can be adjusted in time when the support reaction force is larger, and can be used for correcting the deviation transversely in time. The pushing process almost has no damage to the girder, and the pushing process is smooth and stable. But has the disadvantages of more complex equipment, high mechanical cost and slower pushing speed.
The dragging method has low requirement on the terrain condition, can effectively ensure the splicing precision of the steel beams, can operate continuously, and has high construction speed and short construction period. The main beam is in a passive stressed state, and the adjustable means and methods are limited. The dragging method has the advantages of simple equipment, low cost, low requirements on construction and teaching and small environmental influence. The defects are obvious, the mechanization degree is low, the elevation needs to be adjusted by manually feeding a sliding block, the pier top support reaction force is large, the transverse deviation control capability of the beam body is low, the linear control capability in the pushing process is weak, the risk avoiding capability is poor, and meanwhile, an anchor pulling system needs to be arranged on the beam body.
Generally speaking, the dragging method has low cost, high speed, poor stability, high walking method cost, low speed and good stability. At present, the method has more low application in the engineering field.

Detailed Description
The features of the present invention and other related features are described in further detail below by way of example in conjunction with the following drawings to facilitate understanding by those skilled in the art:
as shown in fig. 1-2, reference numerals 1-10 in the drawings denote: tetrafluoroethylene slide 1, corrosion resistant plate 2, ram 3, vertical limit stop 4, arc tetrafluoroethylene slide 5, vertical limit stop 6, vertical spring 7, cushion rubber 8, protection steel pad 9, vertical distribution beam 10.
Example (b): the ram device capable of automatically adjusting the height and the inclination angle comprises the ram 3, the ram 3 can be used as a support body to support a dragging structure, particularly a bridge body in dragging construction, and the ram device can automatically adapt to the change of the curvature of the bottom of the bridge, namely, the height and the inclination angle can be automatically adjusted.
Specifically, as shown in fig. 1 and 2, in order to reduce the sliding friction force between the ram 3 and the dragging structure, a stainless steel plate 2 and a tetrafluoroethylene sliding plate 1 are laid on the top surface of the ram 3 as a sliding friction reduction device, wherein the stainless steel plate 2 is directly laid above the ram 3, the tetrafluoroethylene sliding plate 1 is laid above the stainless steel plate 2, and the area of the tetrafluoroethylene sliding plate 1 is matched with the contact area between the dragging structure, i.e. the tetrafluoroethylene sliding plate 1 is used as the contact surface between the dragging structure and the ram 3, so that the sliding friction force between the dragging structure and the ram 3 during dragging is reduced through the tetrafluoroethylene sliding plate 1 and the stainless steel plate 2, thereby facilitating the dragging construction of the dragging structure.
The bottom of the ram 3 is provided with vertical springs 7, and the vertical springs 7 are uniformly arranged below the ram 3; supported by the weight of the towing structure and the vertical springs 7, the ram 3 will move downwards with a certain elastic displacement, so that the interaction force between the ram 3 and the towing structure is increased. When the bottom surface of the dragging structure is not flat, the ram 3 can automatically form a corner through the inconsistent compression of the front and rear vertical springs 7 so as to adapt to the curvature change of the bottom surface of the dragging structure, particularly the curvature change of the bottom of the bridge when the dragging method is applied to the bridge body constructed by the dragging method.
During construction, the ram 3 is erected on the longitudinal distribution beam 10, and in order to prevent the ram 3 from vertically popping out of the longitudinal distribution beam 10, longitudinal limit stops 6 capable of longitudinally limiting the ram 3 and vertical limit stops 4 capable of vertically limiting the ram 3 are respectively arranged on the longitudinal front side and the longitudinal rear side of the ram 3. Referring to fig. 1 and 2, the longitudinal limit stops 6 are symmetrically arranged on the longitudinal front and rear sides of the ram 3, and the vertical limit stops 4 are also uniformly and symmetrically arranged along the longitudinal direction of the ram 3 to ensure the limiting effect and stability. In order to prevent the ram 3 from being blocked in the rotating process, the arc-shaped tetrafluoro sliding plate 5 is arranged at the position of the front and rear longitudinal limit stop 6 so as to reduce the rotating friction of the ram 3 when the ram is rotated under pressure.
When the vertical load of the towing structure exceeds the bearing capacity of the vertical springs 7, the ram 3 is pressed and falls on the protective steel pad 9 arranged below the ram to avoid damage caused by directly pounding on the longitudinal distribution beam 10. Meanwhile, in order to reduce impact force, a buffer rubber pad 8 is paved on the protective steel pad 9, and the vertical spring 7 is protected from being damaged.
The elastic function of the ram is realized through the structure in the embodiment, and the whole elastic ram is arranged on the longitudinal distribution beam 10 and can be flexibly arranged according to the position of the lower temporary support.
The ram device in this embodiment has the following application method:
after the temporary buttress is dragged for construction, the installation position of a longitudinal distribution beam 10 is reserved, a protection steel pad 9, a buffer rubber pad 8 and a vertical spring 7 are arranged on the longitudinal distribution beam 10, then a ram 3 is installed, and a stainless steel plate 2 and a tetrafluoroethylene plate 1 are laid on the top surface of the ram 3. In order to limit the longitudinal and vertical displacement of the ram 3, a longitudinal limit stop 6 and a vertical limit stop 4 with an arc tetrafluoro slide plate 5 are installed. After the construction of the ram 3 is completed, the ram can be used as a support position to support the dragging structure, so that the dragging construction of the dragging structure can be carried out by using the ram.
In the embodiment, in specific implementation: the vertical spring 7 can be a standard swing bolster spring, the height of the spring is about 20cm, when the vertical spring is applied to the pushing or dragging construction process of a bridge, the curve difference of the bottom of a main beam is within 10cm, the ram device applicable to the embodiment can not be used for cushion copying construction, and manpower, material resources and time can be greatly saved. When in use, the steel pad is fully protected by the protection 9, and the spring can be ensured not to be damaged. The vertical spring 7 is sleeved and combined by adopting a plurality of layers of spiral springs to ensure the supporting force of the vertical spring; and when the single-point support reaction force is larger, the single-point support reaction force can be used side by side, so that the elastic bearing capacity of a single ram can be greatly improved.
Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims, and therefore, they are not to be considered repeated herein.
