Detailed implementation manners

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0025] Please refer to Figures 1 - 4 , the present application provides a new technical solution: a maintenance support device for high-speed rail track slabs, including a maintenance pool 1 and a track slab 4. The maintenance pool 1 is used for soaking and maintaining the manufactured track slab 4, and the maintenance period is generally about three days. The track slab 4 is vertically placed inside the maintenance pool 1. A track slab support base 2 for supporting the track slab 4 is provided at the bottom of the maintenance pool 1. The track slab support base 2 is a long strip structure, and its front and rear ends are attached to the left and right inner walls of the maintenance pool 1. A plurality of support grooves 6 for the track slab 4 to stand upright are provided on the upper end surface of the track slab support base 2 along its length direction. The bottom of the track slab is placed in the support groove 6. A support clamping mechanism is arranged inside the support groove 6 for supporting, clamping and fixing the track slab 4;

[0026] The support clamping mechanism includes a support plate 61 and two clamping plates 69. The support plate 61 is arranged at the bottom of the support groove 6 and is used for supporting the track slab 4. The two clamping plates 69 are located on both sides of the support groove 6 and are used for clamping the track slab 4. The support plate 61 and the two clamping plates 69 are connected by a link mechanism. By arranging the link mechanism, when in use, the track slab 4 is placed inside the support groove 6 and then contacts the support plate 61 inside the support groove 6. When the support plate 61 moves downward, the two clamping plates 69 are driven to move inward by the link mechanism to clamp the track slab 4, so as to achieve the purpose of supporting and clamping the track slab 4.

[0027] In some embodiments, the link mechanism includes two sliders 62 slidably connected to the bottom of the support groove 6. Two inclined grooves 63 are respectively formed on the surfaces of the two sliders 62 and are inclined outward. A first sliding rod 66 is slidably connected inside the inclined groove 63. When the slider 62 slides downward, the first sliding rod 66 can be driven to move horizontally inward through the inclined groove 63.

[0028] In this embodiment, the clamping plate 69 is slidably connected to both sides of the support groove 6 through a second sliding rod 68. The first sliding rod 66 and the second sliding rod 68 are connected by a link plate 67, and the movement of the first sliding rod 66 can drive the second sliding rod 68 to move synchronously.

[0029] In this embodiment, the first sliding rod 66 and the second sliding rod 68 are both limited by sliding sleeves 65 to ensure the stability of their movement process.

[0030] Specifically, when clamping and fixing the track slab 4, first, the track slab 4 is hoisted above the curing pond 1 by a lifting device, and then the track slab 4 is moved downward and placed inside the support groove 6, so that the bottom of the track slab 4 contacts the support plate 61. Then, under the action of the self-gravity of the track slab 4, the support plate 61 is driven to move downward, thereby driving the slider 62 to slide downward along the support groove 6. Then, the first sliding rod 66 is driven to move horizontally inward through the sliding groove 63 on the slider 62, thereby driving the second sliding rod 68 to move synchronously. The two clamping plates 69 are pushed by the second sliding rod 68 to clamp and fix the track slab 4.

[0031] In some embodiments, a spring 64 is arranged at the bottom of the slider 62. When the track slab 4 is lifted from the support plate 61, the slider 62 drives the support plate 61 to reset under the elastic action of the spring 64, so that the clamping plate 69 is reset synchronously.

[0032] In some embodiments, a number of sets of mounting seats 3 are fixedly installed on the inner walls of the front and rear sides of the curing pond 1. The adjacent mounting seats 3 are equidistantly arranged in the left-right direction on the same horizontal plane, and the distance between adjacent mounting seats 3 is slightly larger than the thickness of the track slab 4, so as to facilitate the placement and fixation of the track slab 4. A cross bar 5 is arranged between each set of corresponding mounting seats 3, and the adjacent track slabs 4 are separated and fixed by the cross bar 5.

[0033] In some embodiments, a dovetail groove 31 is arranged on the mounting seat 3. Clamping blocks 51 are fixedly installed at both ends of the cross bar 5. The clamping blocks 51 are adapted to the dovetail groove 31. During use, the cross bar 5 is hoisted by a lifting device, and the clamping blocks 51 on both sides of the cross bar 5 are clamped into the dovetail groove 31, so that the cross bar 5 can be fixed inside the mounting seat 3, avoiding the phenomenon that the cross bar 5 shakes left and right inside the mounting seat 3, and can support the adjacent track slabs 4.

[0034] In this embodiment, anti-collision strips 52 are respectively installed on both sides of the clamping block 51. The anti-collision strips 52 are made of rubber material, which can ensure that the track slab 4 is not damaged.

[0035] Working principle: When the high-speed rail track slab maintenance support device is in use, first, the track slab 4 is hoisted above the maintenance pool 1 by a lifting tool, and then the track slab 4 is moved downward and placed inside the support groove 6, so that the bottom of the track slab 4 contacts the support plate 61. Then, under the action of the self-weight of the track slab 4, the support plate 61 is driven to move downward, and then the clamping plates 69 on both sides inside the support groove 6 are driven by a link mechanism to clamp and fix the track slab 4. Then, the cross bar 5 is lifted by a lifting tool, and the clamping blocks 51 on both sides of the cross bar 5 are clamped into the dovetail groove 31, so that the cross bar 5 can be fixed inside the mounting seat 3, avoiding the phenomenon of left and right shaking of the cross bar 5 inside the mounting seat 3, and can support adjacent track slabs 4, further improving the stability of the support.

[0036] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
