[0029] The sliding trolley is slidably installed on the slideway, and the sliding trolley is connected to the power structure.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The present invention provides a heavy-load lateral sliding system in a cable hoisting system, wherein: (1) a tower top crossbeam and a wind cable are used as a load-bearing lateral sliding stabilizing structure to effectively ensure the stability of the heavy-load lateral sliding system; a slideway and a sliding trolley are used as the sliding structure, and a polytetrafluoroethylene plate is installed at the bottom of the sliding trolley, a limit pulley is installed on the side, and a 301 stainless steel plate is laid on the slideway, and paraffin oil is applied between the slideway and the sliding rail of the sliding trolley and between the polytetrafluoroethylene plate and the stabilizing structure for lubrication to ensure the smooth, uniform and flexible sliding of the sliding structure; and a through-core jack and supporting high-pressure oil pump equipment, precision-rolled threaded steel, reaction support frame and other tensioning facilities are used as the lateral sliding traction power structure to effectively ensure that the sliding structure is uniform and smooth during lateral movement without being stuck. (2) The sliding boat type heavy load lateral movement system in the cable hoisting system provided by the present invention overcomes the conventional empty load lateral movement to the bridge design axis, which requires an open and flat site to ensure that beams, arches and other lifting objects are transported to the dedicated operating platform below the vertical lifting, thereby saving the costs of site excavation, filling, masonry and hardening of the site, and setting up other special platform facilities; secondly, it can increase the construction speed and reduce the use time of equipment and materials by assembling and storing large sections in advance, thereby saving costs. (3) The sliding boat type heavy load lateral movement system in the cable hoisting system provided by the present invention overcomes the safety risks in the fixed saddle hoisting when the site is limited and the heavy objects need to be swung at a large angle, and in the oblique pulling and oblique lifting. (4) The sliding boat type heavy load lateral movement system in the cable hoisting system provided by the present invention has green and environmental benefits in bridge engineering construction. In conventional hoisting, an open and flat site is required to ensure that beams, arches and other lifting objects are transported to the dedicated operating platform below the vertical lifting, reducing the environmental damage caused by large-scale excavation and construction of the mountain, and ensuring the integrity of the original terrain. (5) In the heavy-load transverse sliding system of the cable lifting system provided by the present invention, paraffin oil plays a huge role in the operation of the present invention. Paraffin oil is a homemade grease, and its formula quality ratio is: paraffin: engine oil = 1:1. The paraffin is first melted at high temperature, and then the engine oil is promptly added for fusion and stirring. Before the paraffin solidifies, it is promptly applied to the surface of the stainless steel slide. Since paraffin is a solid material, the paraffin oil applied to the slide can solidify on the slide in a short moment to form a layer of solid grease. When the solid grease is squeezed up and down, it will produce a certain resistance. Compared with other more diluted greases, the effect of this homemade paraffin grease is very obvious. (6) In the sliding boat type heavy load lateral movement system of a cable lifting system provided by the present invention, the side horizontal limit wheel plays a huge role in the operation of the present invention. Since the angles between the tower and the back cable, and between the tower and the mid-span load-bearing cable are different, the horizontal thrust exerted on the saddle during the lifting process greatly increases the frictional resistance of the saddle lateral movement. The side horizontal limit wheel reduces the frictional resistance by replacing the sliding friction with rolling friction, and plays a vital role in the present invention.

[0032] In addition to the above-described objects, features and advantages, the present invention has other objects, features and advantages. The present invention will be further described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] As a further embodiment of the present invention, the present invention also provides a method for constructing the sliding boat type heavy load traverse system in the above-mentioned cable hoisting system, comprising the following steps:

[0054] Step 1: Preliminary preparation;

[0055] Before construction, the stability and load calculations of the tower top beam, the sliding trolley and the tower frame in the pulley-type saddle cable hoisting system were carried out;

[0056] Formulate detailed construction plans and proposals based on actual conditions, draw up plan drawings, compile safety measures, and clarify the construction process and technical requirements for load-carrying transverse movement;

[0057] Prepare materials for heavy-load traverse systems, and cut, process and manufacture according to the requirements of the plan drawings;

[0058] Complete the preliminary preparations.

[0059] Step 2: Install the heavy-load lateral movement system;

[0060] S2.1, install a stable structure;

[0061] ① Divide the tower top cross beam into standard section, transition section, reinforcement section, cross brace section and column cap section; assemble the tower top cross beam as a whole and hoist it to the installation site;

[0062] ②, install the tower to the column cap section, and then install three distribution beams on the column cap section along the longitudinal direction of the bridge (the connection between the column cap section and the distribution beam is specifically that the top plate in the column cap section and the bottom steel plate in the distribution beam are connected to each other by full welding); specifically, the distribution beam is configured as a box beam force-bearing assembly formed by welding steel plates of different specifications and models;

[0063] ③. Connect the top plate in the distribution beam and the other bottom plates in the tower top cross beam by full penetration welding to complete the installation of the tower top cross beam;

[0064] ④. Level the tower top beam; Specifically, before the tower top is capped, since there may be a 1-2CM length deviation at each column head position of the tower frame, it is necessary to use a level to measure the elevation of each column head, and take the highest column head elevation as the standard, and add pads to the remaining column heads to make the elevation of each column head reach the same horizontal height. Since the cable towers on both sides are located at the central axis of the cable tower and are in a parallel state, the center point position and elevation of the distribution beam are measured using a total station to ensure that the tower top beam is placed in a vertical position relative to the distribution beam during installation. If there is an elevation error during installation, use the same method to add pads under the tower top beam;

[0065] ⑤. Install the limit baffle and wind cable on the tower top beam in sequence to complete the installation of the stable structure.

[0066] S2.2, install the sliding structure and the power structure;

[0067] ①. Install the slideway on the tower top beam; specifically, the slideway is set as a steel box structure formed by welding steel plates, and a limit device is set on the slideway, and a sliding slideway is welded on the sliding surface of the slideway, and homemade paraffin grease is applied on the sliding slideway to ensure that the friction coefficient of the slideway surface is less than 0.15; at the same time, in order to ensure that the cable crane load-bearing cable system can be positioned at any time during transverse movement, a triangular limit wedge block is set on the sliding slideway to position the saddle and prevent the saddle from moving;

[0068] ② Assemble the sliding trolley, polytetrafluoroethylene plate and limiting pulley to form a sliding assembly;

[0069] ③. Install a stainless steel slideway that matches the sliding slideway at the bottom of the sliding assembly, and apply paraffin oil on the stainless steel slideway for lubrication;

[0070] ④. Using a set of threaded holes reserved at the bottom of the sliding trolley, string two pieces of 7.5-meter-long fine-rolled rebars and one piece of 8-meter-long fine-rolled rebar (the fine-rolled rebar is part of the jack-fine-rolled rebar tensioning equipment) together through the connecting sleeve, and then put the fine-rolled nuts on both sides of the sliding trolley. Then, the two ends of the fine-rolled rebar pass through the suturing plate and the jack reaction seat in the jack-fine-rolled rebar tensioning setting, and then install the hydraulic jack. It should be noted that when installing the hydraulic jacks at both ends of the tower top beam, the inner core of the jack at one end must be in the jacking state, and the other end must remain stationary. At the same time, install the fine-rolled nuts on the outside of the jacks at both ends. As a result, the inner core of the jack in the jacking state of the sliding trolley falls back to retract and release the finely rolled threaded steel and tighten the finely rolled nut (the threaded steel needs to reserve a length to facilitate tensioning, retracting and moving the saddle), and the jack at the other end begins to lift and tension the threaded steel and loosen the finely rolled nut. When the sliding trolley is moving horizontally, it is necessary to pay attention to manually turning the position of each finely rolled nut in time to prevent the saddle set on the sliding trolley from being stuck and affecting the horizontal movement. However, the nut should not be turned too far when turning. If the saddle suddenly slides when moving from the middle of the beam to the edge, the rear anchor and the rock saddle will present a mechanism similar to that of a slingshot. Therefore, in order to ensure the limit, the finely rolled nut cannot move too much at one time. When the saddle moves horizontally to the predetermined position, the nut is tightened to fix the position of the saddle and the hydraulic jack.

[0071] As a further embodiment of the present invention, after the heavy-load lateral movement system is installed by the above construction method, the following heavy-load lateral movement examples are performed through trial lifting and actual lifting:

[0072] Before the trial lifting, the trial lifting platform and the test lifting object are placed in the lifting position, and the saddle transverse flat car is moved horizontally to the corresponding lifting point without load. During the trial lifting, 50%, 100% and 110% of the maximum lifting weight of the steel pipe arch rib of 104.2T are tested. After loading step by step, the test objects of different weights are subjected to load transverse movement tests 30m in front of the Guiyang bank tower, in the middle of the span, and 20m in front of the Pingtang bank tower.

[0073] The test results show that the lateral tower deviation is within 1cm when the load is lateral, the lateral movement is smooth with low friction, and the tensioning force of the jack-finished rolled rebar tensioning equipment is small. It also verifies the feasibility of the lateral movement of the load, good stability, high safety performance, strong economy, simple operation, convenient and fast, and can be widely used.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
