[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] In the following description, specific details such as specific internal procedures and techniques are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0025] like Figure 1-6 As shown, the utility model provides an elevator combined double main cable saddle, wherein the double main cable saddles are separately arranged, and the elevator is arranged between the separated saddles. The saddles include two, which are respectively arranged on both sides of the elevator. The saddles include a saddle groove 1, a saddle body 2, a connecting steel pipe 3 and a base 4. The saddle groove 1, the saddle body 2, the connecting steel pipe 3 and the base 4 are connected from top to bottom. The saddle groove 1, the saddle body 2 and the base 4 are arranged to be integrally formed, and the connecting steel pipe 3 is connected to the saddle body 2 by bolts 6.

[0026] The saddle groove 1 includes a bolt column, a sleeve 9, a bolt 6, a wedge 10, a pressure plate 11 and a zinc block 12. The bolt column, the sleeve 9, the bolt 6, the wedge 10, the pressure plate 11 and the zinc block 12 are arranged in the saddle groove. The wedge 10 is pressed on the pressure plate 11, and the pressure plate 11 is connected to the bolt column. The sleeve 9 is outside the bolt column, and the wedge 10 is fixed by bolts.

[0027] The base 4 includes an upper seat plate 13, a stainless steel plate 14, a polytetrafluoroethylene plate 15, a mounting plate 16 and a base plate 17, which are connected in sequence from top to bottom; the base 4 is set on the grid 18, and the base plate 17 is fixed on the grid 18. The thickness of the stainless steel plate 14 is set to 8mm. The thickness of the polytetrafluoroethylene plate 15 is set to 4mm. A vertical partition 8 is set in the saddle groove 1 along the bridge direction.

[0028] The inner groove of the saddle is set to 544mm. The saddle body is set to a fully cast structure.

[0029] The stainless steel plate 14 and the polytetrafluoroethylene plate 15 are configured as a stainless steel-polytetrafluoroethylene slide plate.

[0030] The length of a combined double main cable saddle of an elevator in this embodiment is set to 6.65m, and the total width inside the saddle is 544mm. The forked interior where the main cable 5 is placed is the saddle groove 1, and the sleeve, bolts, wedges, pressure plates and zinc blocks are arranged in the saddle groove; the main cable 5 is also placed in the saddle groove 1. In order to reduce the friction resistance of the saddle push operation, a stainless steel plate-polytetrafluoroethylene slide plate is arranged under the saddle body to adapt to the relative displacement during construction. Among them, the stainless steel plate-polytetrafluoroethylene slide plate and the saddle body are mutually separated structures. The stainless steel plate-polytetrafluoroethylene slide plate reduces the resistance of the saddle body movement. The stainless steel plate-polytetrafluoroethylene slide plate is arranged under the saddle body, and the saddle body can move on the stainless steel plate-polytetrafluoroethylene slide plate.

[0031] The main cable is used to connect the bridge deck, and the saddle groove supports the main cable. In order to increase the friction resistance between the main cable and the saddle groove and facilitate the positioning of the cable strands, vertical partitions are set in the saddle groove along the direction of the bridge. After all the cable strands are in place and adjusted, the top of the cable strands are filled with zinc filling blocks, and then the side walls of the saddle groove are tightened with bolts and pull rods.

[0032] The utility model is an elevator combined double main cable saddle which is usually arranged at the top of the bridge tower. A slide plate is arranged under the saddle, and a pressure steel plate is arranged under the slide plate. A steel grille is arranged under the pressure steel plate, and the steel grille is consolidated into one with the concrete at the top of the tower. Therefore, a grille base and a reaction frame are arranged at the top of the bridge tower. The bottom of the grille is located below the saddle, and the reaction frame is located on the side of the saddle. The reaction frame is welded to the grille. When the jack is used to push the saddle to move, the jack is pressed against the reaction frame, and the reaction frame transmits the load to the grille, and the grille transmits the load to the top of the tower, and then to the bridge tower.

[0033] Therefore, the reaction frame is suspended outside the tower top to place the jack for controlling the movement of the saddle body. After the saddle body is pushed into place, the suspended reaction frame part is cut off. The grid is required to have a flat surface, form an integral part with the tower top and have sufficient vertical bending rigidity. Therefore, a lattice structure is adopted in the vertical and horizontal directions, with a lattice-shaped top and bottom plate on the top and bottom to form a grid with an I-shaped cross-section in both the vertical and horizontal directions. Anchor steel bars are set in the grid and filled with concrete.

[0034] The construction process of an elevator combined double main cable saddle of the utility model is as follows:

[0035] The utility model is a cast-welded combined structure for a combined double main cable saddle for an elevator. A polytetrafluoroethylene plate is provided under the saddle body to facilitate the saddle top-pushing construction. After the partitions and cable strands in the saddle groove are all in place and adjusted, the top is filled with zinc filling blocks, then pressed with a cover plate, and then the side wall of the saddle groove is tightened with a pull rod with 50KN as a level, and the final tightening force is 200KN. The main cable saddle is made of ZG275-485H cast steel material, with a total weight of about 53.9 tons and a maximum hoisting weight of about 27.2 tons. The connecting steel pipe is Q235B, and is flange-connected to the saddle after the saddle top-pushing is completed. After the saddle is pushed into place, the secondary span side baffle is installed.

[0036] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
