In actual work progress, cavity structure 31 part is wrapped up in the post-cast strip concrete, and top cap 32 is then installed on cavity structure 31's top panel 31b, when needs are maintained the part that is located cavity structure 31, the accessible is demolishd top cap 32's mode and is made telescoping device 1 can be demolishd and realize inner structure's maintenance and maintenance, this kind of structure provides the operating space of work needs for telescoping device's detection and maintenance, it is also more convenient simultaneously to make whole telescoping device's installation, top cap 32 directly contacts with the road edge simultaneously, thereby can support the effectual life who prolongs this part to the road edge through it.

With continued reference to fig. 3, the structure enclosed as the cavity structure 31 includes, in addition to the top plate 31b, a bottom plate 33 parallel to the top plate 31b, side plates 34 at both sides of the opening 31a, and a back plate 35 connecting the two side plates 34. Above-mentioned each panel accessible welded mode is realized fixedly, also can fix through structures such as connecting piece, selects according to actual needs, and two kinds all have respective advantage, a cost is cheap relatively, another kind convenient to detach and equipment. Although the two side plates 34 may be disposed in an open manner or in a gathered manner in a direction toward the opening 31a, it is preferable to dispose the two side plates 34 in parallel in consideration of various aspects such as processing, transportation, and appearance.

In the above embodiment, the cavity structure 31 is used for accommodating both ends of the displacement mechanism 2, and in this case, as shown in fig. 5, the side plates 34 are preferably disposed to be inclined with respect to the direction perpendicular to the back plate 35, in which case, at least one of the first portion S1 and the second portion S2 may be in such a form that during the displacement of the displacement mechanism 2, the occurrence of interference can be avoided, and the support beam 21 in the displacement mechanism 2 is more suitable for the inclined arrangement, and the second portion S2 is shown to be inclined, and during the use of the modular expansion device, the support beam 21 inclined with respect to the side beam 11a can obtain a larger displacement space by the inclined arrangement of the side plates 34.

As a preference of the above embodiment, the side plate 34 is externally provided with a convex structure 34 a. As shown in FIG. 5, through the arrangement of the convex structures 34a, the shear force of the deflection box in the post-cast strip concrete after the installation is completed can be improved, and the stability of the installation is ensured, wherein the convex structures 34a can be selected from shear nails.

As a preferred embodiment, with continued reference to fig. 1, 3 and 4, the top plate 31b is provided with a threaded counter bore for fixing the connecting member 36 penetrating through the top cover 32, which can reduce the difficulty of connecting the top cover 32 with respect to the top plate 31b, and only needs to be screwed directly through the threads after penetrating through the top cover 32. Wherein, the top cover 32 is provided with a sinking part at the top of the hole site for installing the connecting piece 36, so that the connecting piece 36 can be embedded into the top cover 32, and the influence on the normal running of the vehicle and the like caused by the formation of a bulge on the road surface is avoided.

Preferably, the connecting piece 36 penetrating through the top plate 31b penetrates through the convex edge 11c and is connected with the top cover 32, and in the optimization mode, synchronous connection of the three is achieved, so that on one hand, the connection difficulty is reduced, on the other hand, when the connecting piece is installed by contacting with the top cover 32, the connection between the convex edge 11c and the top plate 31b can be released, and the maintenance difficulty is reduced. Wherein, the top cover 32 is provided with a groove body for accommodating the convex edge 11 c. Through the mode that sets up the cell body on top panel 31b, because top cap 32 is independent structure, need not make up the concatenation with other panel, and processing is easier, still can make the boundary beam 11a arrange the surface of top panel 31b in and obtain bigger operating space.

In the course of specific use, the first portion S1 and the second portion S2 may be equally sized or may be selected according to different sizes, for example, as is clear from fig. 1 and 3, the first portion S1 and the second portion S2 are different in size, and such size changes may be selected for installation, machining, etc., but the first portion S1 and the second portion S2 are identical in structure.

In order to ensure that the support beam 21 can stably guide the sliding rubber support 22 during the movement of each beam 11, the sliding rubber support 22 includes two parts disposed above and below the support beam 21, and is rotatably connected to the mounting structure 37 fixedly disposed on the middle beam 11.

As shown in fig. 6 to 8, the mounting structure 37 includes a top support 37a and a bottom support 37b, parallel mounting surfaces are disposed between the top support 37a and the bottom support 37b, the two support are symmetrically provided with connecting portions 37c about the beam 11, the beam 11 is longitudinally provided with at least two through holes, the through holes are internally connected with mounting rods 37d through threads, the connecting portions 37c are provided with linear holes extending along the distribution direction of the two through holes, the width of the linear holes is equal to the diameter of the through holes, the linear holes are guided by the mounting rods 37d to adjust the up and down positions, and the linear holes are fixed by nuts connected with the mounting rods 37d through threads after being adjusted in place.

In the process of installing the mounting structure 37, the sliding rubber support 22 and the support beam 21, at least two through hole sites are required to be formed on the beam body 11 in the longitudinal direction, then the mounting rod 37d is screwed into the through hole sites and is connected with the through hole sites through threads, and then the top support 37a and the bottom support 37b are fixed one by pressing through nuts, wherein the mounting surface between the two is shown in fig. 7 and comprises a first plane 37e positioned on the top support 37a and a second plane 37f positioned on the bottom support 37b, wherein the distance between one of the first plane 37e and the second plane 37f relative to the beam body 11 can be firstly determined, so that a plurality of support points of the support beam 21 can be located at the same height, the deformation of the support beam 21 is avoided, and in the process, through the arrangement of the straight hole sites, the height can be finely adjusted, and then the unfixed side of the first plane 37e or the second plane 37f is fixed, so that the final required installation height can be determined, in the process, due to the adjustability of the height, the installation difficulty can be effectively reduced, and the balance of the support of the final support beam 21 at all positions is ensured, wherein preferably, the top support 37a and the bottom support 37b are both set to be opposite C-shaped structures, and the spring structure 37g can be arranged between the top support 37a and the beam body 11, so that the vibration process is alleviated, and the noise is reduced. In the process of the adjustment, although the two mounting rods 37d and the linear hole have a guiding function, the top support 37a and the bottom support 37b are prevented from rotating, and the linearity of the relative movement of the two support is ensured, because the length of the bottom support 37b is large, in order to further ensure the accuracy of the guiding, it is preferable to provide a guiding strip 37h on the inner wall of the bottom support 37b, and to make the edge of the top support 37a and the guiding strip 37h adaptively provided with a guiding groove. In the specific implementation process, due to the climate, expansion and contraction of the expansion joint inevitably occur, and this situation may cause interference between two adjacent mounting structures 37, for this reason, the beam body 11 for mounting the mounting structures 37 in the preferred embodiment may have a width difference between the upper edge and the lower edge as shown in fig. 9, and specifically, the width of the lower edge may be set to be smaller than that of the upper edge, so that the mounting structures 37 are retracted inward relative to the upper edge in the direction of the width of the beam body 11, thereby avoiding the occurrence of interference. Wherein the top of the upper edge is used for mounting the noise reduction system 6. Wherein, noise reduction system 6 can include a plurality of diamond that make an uproar that fall, and the welding of the diamond that makes an uproar is on 11 surfaces of roof beam body, reduces the rhythmical noise that the vehicle produced when passing through, is equipped with GU system (the folding sound-proof screen of polyurethane) simultaneously in telescoping device below, keeps apart the propagation of telescoping device below noise.

As a preferable example of the above embodiment, as shown in fig. 10 and 11, the sliding rubber mount 22 is covered with a composite structure 23 at least on a horizontal sliding contact surface with the support beam 21, and the composite structure 23 includes a metal mesh 23a conforming to a rubbing direction and a modified polytetrafluoroethylene structure 23b covering the outside of the metal mesh 23 a. At present, Polytetrafluoroethylene (PTFE) is mostly adopted as a main structure of a sliding support which is conventionally used, and the bearing capacity of the PTFE is sharply reduced when the use temperature of the PTFE exceeds 30 ℃, and the PTFE can not be used any more when the use temperature of the PTFE is lower than-35 ℃. PTFE becomes powder after sliding for 10km under the test conditions of v =2mm/s and p =30N/mm2, so that the PTFE is only suitable for being used as a sliding material under the conditions of low speed, low bearing, low requirement on friction coefficient, no requirement on service life and oil lubrication. In this preferred scheme, for original holistic polytetrafluoroethylene structure, composite construction 23's setting has improved sliding support sliding friction part's wearability, has also played holistic reinforcing effect to the sliding rubber support 22 that realizes the buffering simultaneously to improve whole sliding support to high-speed, high bearing, high coefficient of friction's bearing capacity, prolonged life, realized more reliable self-lubricating. After the metal mesh 23a is processed, the modified polytetrafluoroethylene structure 23b can be rolled by a rolling mill, and the rolled combined structure 23 is sintered under the protection of nitrogen.

The metal mesh 23a is preferably a copper mesh structure because of its high thermal conductivity, corrosion resistance and easy processing and forming, so that the formed composite structure 23 can be more conveniently attached to the surface of the sliding rubber support 22, wherein the two can be fixedly connected by adhesion, which can reduce the thickness of the composite structure 23 as much as possible, and of course, the connection by a connecting member is also within the protection scope of the present invention.

With continued reference to fig. 10 and 11, the metal mesh 23a is disposed parallel to the friction surface, so that the metal mesh 23a can be more compliant with the force applied to the shoe, and the compliant extension of the metal mesh and the friction surface can accelerate heat conduction, improve uniform contact between the modified ptfe structure 23b and the supporting structure thereof, and prolong the service life.

As a preference of the above embodiment, the metal mesh 23a completely covers the friction surface after being projected on the friction surface, so as to ensure that the reinforcing effect of the whole friction surface is equal, and avoid the formation of a breaking point due to local weakness, thereby influencing the service life of the whole friction surface.

The metal mesh 23a includes only one layer, or is a multi-layer assembly, and when the metal mesh 23a is a multi-layer copper mesh assembly, the layers are fixedly connected to each other, or stacked in rows. Specifically, the number of the expanded metal 23a may be determined according to a specific friction condition and the size of the cross section of the metal wire constituting the expanded metal, wherein, when the expanded metal 23a is a combination of a plurality of layers, the layers may be first connected by rolling, or the layers may be simply stacked together in a row to be rolled with the modified polytetrafluoroethylene structure 23 b. As shown in fig. 12, a case where a plurality of layers of metal nets 23a are provided and each layer of metal net 23a includes only one layer is shown, as shown in fig. 13, a case where a plurality of layers of metal nets 23a are provided and each layer of metal net 23a includes three layers is shown, and combinations of the above and other numbers are within the scope of the present invention.

As a preference of the above embodiment, each part of the sliding rubber support 22 includes 3N friction surfaces 22a, the friction surfaces 22a are all rectangular, and each 3 friction surfaces 22a are connected end to end in sequence to form a convex structure, or connected end to end in sequence to form a concave structure, where N is a positive integer, and can be selected according to actual needs. As shown in fig. 14, when three friction surfaces 22a are connected end to form a convex structure, they are embedded in the concave areas of the supporting beam 21, so that the relative sliding between them can ensure linearity, wherein fig. 15 and 16 show two structural forms of the sliding rubber support 22, one is embedded in the supporting beam 21 completely, and the other is embedded in the supporting beam 21 partially, and it should be noted that the combined structure 23 only covers the friction surfaces 22a of the sliding rubber support 22, which can effectively reduce the cost.

In fig. 17 and 18, it is shown that when the three friction surfaces 22a are connected end to form a concave structure, the periphery of the supporting beam 21 is partially covered so that the relative sliding between the two can ensure linearity, and similarly, the combined structure 23 only covers the friction surface 22a of the sliding rubber support 22. The friction surface 22a in the form of a curved surface is not described in the present invention because it is very difficult to manufacture during the manufacturing process. The cross section of the convex structure or the concave structure is rectangular or isosceles trapezoid. Wherein the support beam 21 may be partially covered with a stainless steel plate for contact with the sliding rubber mount 22, thereby reducing the friction coefficient at low cost.

In the above embodiment, in order to achieve the purpose of "anti-vibration", it is often necessary to reinforce the strength and rigidity of the structure by increasing the structure size and the like, so as to counter the mechanical energy of various complex multidimensional vibrations, which increases the cost of the whole device on one hand, and further reduces the maintenance space by increasing the size on the other hand, as a preference of the above embodiment, the intelligent multifunctional module type telescopic device further includes the damping structure 4, and both ends of the damping structure 4 are respectively installed inside the first part S1 and the second part S2.
