A Chinese patent with the authorized publication number CN115182753B discloses a S-bend full-face lining formwork system for inclined shaft and a lining construction method, which specifically discloses that the lining formwork system comprises an upper bend segment formwork system for constructing the lining of the upper bend segment of the inclined shaft, a slant straight segment formwork system for constructing the lining of the slant straight segment of the inclined shaft and a lower bend segment formwork system for constructing the lining of the lower bend segment of the inclined shaft, the upper bend segment formwork system, the slant straight segment formwork system and the lower bend segment formwork system are all spliced by a plurality of annular formwork splicing segments with gradually changing width, each annular formwork splicing segment comprises two width gradually changing side molds and a top mold and a bottom mold connected between both ends of the two width gradually changing side molds, respectively. By adjusting the direction of the narrow end of the annular formwork splicing segment, the lining of the upper bend segment of the inclined shaft, the slant straight segment of the inclined shaft and the lower bend segment of the inclined shaft can be simultaneously formed by one-time construction, the elastic change of the slip-form steel strand can be eliminated, secondary treatment is not needed, the construction efficiency can be effectively improved, the construction safety risk can be reduced, and the problems of the upper bend segment and the lower bend segment being unable to be constructed and the triangular area of the slant straight segment being unable to be constructed in the conventional method and the slip-form construction of the inclined shaft lining can be effectively solved.

Therefore, a through core trolley for inclined shaft lining is needed, which can meet the disassembly and assembly requirements of different body type formworks such as lower bend, slant straight and upper bend.

[0093] In practice, the centering hydraulic cylinder 57 and the guide vertical rod 58 are parallel to the top die lifting hydraulic cylinder 46.

[0094] It should be noted that the centering assembly includes at least two centering hydraulic cylinders 57.

[0095] As Figure 1 and Figure 5As shown, in this embodiment, the slip-resistant mechanism includes two wire rope locking mechanisms respectively installed on both sides of the force transmission plate 4 and a release hook mechanism installed at the rear end of the traction rod 3. The rear end of the traction rod 3 passes through the force transmission plate 4 and is connected to the release hook mechanism. The force transmission plate 4 is fixedly connected to the traction rod 3.

At the same time, the force transmission plate 4, which is fixed to the traction rod 3, moves forward under the sliding cooperation of the force transmission sleeve 7 and the guide cylinder 8, and the rope clamping assembly of the wire rope clamping mechanism releases the safety wire rope 1.

[0099] It should be noted that by using the wire rope locking mechanism and the release hook mechanism together as the trolley's slip prevention mechanism, and since both the wire rope locking mechanism and the release hook mechanism are triggered by the traction system, a double insurance effect can be achieved, thereby maximizing the safe operation of the trolley.

[0109] In specific implementation, the front end of the trolley main body 43 is provided from top to bottom with a plurality of ear plates for rotatably installing the transmission shaft 25.

[0110] In specific implementation, a gear mounting plate 36 for mounting gear sets is fixedly installed at the front end of the trolley body 43. The vertical mounting plate 35 is fixedly connected to the gear mounting plate 36. The first lower gear 26 and the second lower gear 27 are both rotatably mounted on the gear mounting plate 36. The length direction of the rocker arm 29 is parallel to the transmission shaft 25, and the length direction of the transverse slide groove 30 is perpendicular to the transmission shaft 25.

[0111] In specific implementation, a limiting groove 291 is provided on one side of the rocker arm 29 for the end of the force reducing lever 31 to abut. The heavier end of the force reducing lever 31 abuts in the limiting groove 291, and the lighter end of the force reducing lever 31 abuts on the upper part of one end of the release lever 32. The other end of the release lever 32 is hooked to the bottom of the fall arrest hook 33.

[0112] In practice, apart from the winch for traction, all other power for this trolley is provided by the hydraulic system. The hydraulic system includes a hydraulic pump station, four hydraulic cylinders for side mold extension and retraction on each side, one rotary motor on each side, four hydraulic cylinders for top mold lifting and lowering, four hydraulic cylinders for centering, and one hydraulic cylinder for leveling the operating platform 53.

[0113] The pump station and control valves are both installed on the operating platform 53 in the middle of the trolley. For easy observation and operation, the control valves are arranged around the platform railing according to the controlled parts. The hydraulic lines on the trolley use seamless steel pipes with an inner diameter of φ10mm, fixed to the trolley body with pipe clamps. The beginning of the pipe is connected to the control valve interface via a high-pressure rubber hose. Since the operating platform will rotate and level according to the slope of the inclined shaft, a certain amount of slack needs to be reserved for the connecting hose. The end of the pipe is connected to the actuator interface via a clamp connector.

[0114] The control valve is a manually operated three-position four-way directional valve. To improve the actuation accuracy of the actuator, the valves are connected in series.

[0115] Except for the slewing mechanism, all other control circuits are one-to-many, meaning one directional valve controls four hydraulic cylinders. Therefore, four manual ball valves are connected in parallel at the outlet of the directional valve, with each ball valve controlling one hydraulic cylinder. In this way, when high-precision hole-setting operations are required, the forward and backward movement of one cylinder can be controlled independently. In addition, due to the different friction forces of each cylinder, there is a lack of synchronization. The synchronization problem can be manually adjusted by opening and closing the ball valves individually.

[0116] Hydraulic cylinders are mostly used under load. To prevent the hydraulic cylinders from falling back or nodding, each cylinder is equipped with a hydraulic lock for locking.

[0117] like Figure 9 As shown, in specific implementation, when using this invention to reverse-engineer the template, the following steps are included:

[0118] Step one, the trolley chassis 42 and the auxiliary rail trolley 41 are pinned to form a whole trolley, and four bottom molds 37 are added in a bin number at the front end of the bin number where the concrete lining has been constructed;

[0119] Step two, the whole trolley is pulled to the rear end of the bin number where the concrete lining has been constructed through the traction system, then the front end of the auxiliary rail trolley 41 is pinned to the bottom mold 37 of the ring at the rear end of the bin number to be constructed, and the connecting pin between the trolley chassis 42 and the auxiliary rail trolley 41 is removed;

[0120] Step three, the trolley chassis 42 and the trolley body 43 are moved as a whole through the traction system, and after the four ring top molds 39 and the side molds in the bin number where the concrete lining has been constructed are removed from back to front, they are transported and installed in the next bin number; then the remaining top molds 39, side molds and bottom molds 37 in the bin number where the concrete lining has been constructed are removed from back to front, and transported and installed in the next bin number.

[0121] In step three, when the removal, transportation and installation of the formwork are carried out, the removal, transportation and installation are carried out ring by ring, that is, the top mold 39 and the side mold in a ring are removed first, then the trolley passes through the center of the formwork in the bin number where the concrete lining has been constructed, and the removed top mold 39 and side mold are transported to the next bin number and installed, then the trolley chassis 42 and the trolley body 43 are moved as a whole through the traction system to the bin number where the concrete lining has been constructed and the next ring top mold 39 and side mold are removed, and so on; when the four ring top molds 39 and side molds are removed, transported and installed, the bottom mold 37 in the first ring is removed synchronously when the fifth ring top mold 39 and side mold are removed, and so on, to complete the removal of all top molds 39 and side molds in the bin number where the concrete lining has been constructed; then the remaining bottom molds 37 in the bin number where the concrete lining has been constructed are removed, transported and installed from back to front;

[0122] When the top mold 39 and the side mold are removed, the top mold 39 is removed first, then the two side molds are removed, then the top mold 39 and the side mold are transported synchronously, when the top mold 39 and the side mold are installed, the top mold 39 is installed first, then the side mold is installed;

[0123] When the top mold 39 is removed, the piston rod of the four top mold lifting hydraulic cylinders 46 is extended and drives the four guide columns 45 to slide upwards, so that the top mold tray 47 is lifted to below the top mold 39, then the top mold 39 and the top mold tray 47 are connected by bolts, then the connection between the top mold 39 and the side mold is removed, the piston rod of the top mold lifting hydraulic cylinder 46 is retracted to drive the top mold 39 to descend, until the top mold 39 is separated from the side mold, and the removal of the top mold 39 is completed; conversely, the installation of the top mold 39 is carried out;

[0124] When the side mold is removed, the piston rod of the side mold rotating hydraulic cylinder 49 on both sides of the trolley body 43 is extended to drive the guide cross bar 48 to slide outward, and then the two side brackets 50 are moved to the two side molds on both sides, respectively, the two side molds are connected with the two side brackets 50 through bolts, then the connection between the side mold and the bottom mold 37 is removed, the piston rod of the side mold rotating hydraulic cylinder 49 is retracted to drive the two side molds to be recovered until the side mold is separated from the bottom mold 37, and the removal of the side mold is completed;

[0125] When the side mold is installed, when the rotation direction of the side mold needs to be changed, the side mold is rotated by 180 degrees through the rotary drive 51, and then the piston rod of the side mold rotating hydraulic cylinder 49 is extended to install the side mold in place.

[0126] When the bottom mold 37 is removed, the bottom mold 37 is lifted by setting a drop chain on the lifting lug 44; when the bottom mold 37 is installed, the bottom mold 37 is lowered into place through the drop chain.

[0127] In the actual implementation, during the transportation of the mold, when the traction force disappears unexpectedly, the traction rod 3 is reset under the action of the traction rod return spring 5, and then the steel wire rope locking mechanism and the tripping hook mechanism are locked to avoid the trolley from slipping.

[0128] The steel wire rope locking mechanism stops slipping: the force transmission plate 4 fixed on the traction rod 3 moves backward, the force transmission vertical shaft 15 on the force transmission plate 4 drives the push rod 13 to rotate through the connecting rod 14, the push rod 13 cancels the limitation of the shift fork 12 after rotating, the shift fork 12 drives the two rope clamping wedges 11 to move into the rope clamping grooves 9 under the action of the rope clamping return spring 19, and clamps the safety steel wire rope 1 to avoid the trolley from slipping.

[0129] The tripping hook mechanism stops slipping: the force transmission rod 23 fixed at the rear end of the traction rod 3 moves backward, the transmission shaft 25 rotates by 90 degrees under the transmission of the gear and rack transmission mechanism 24, and then the second lower gear 27 is driven to rotate by 90 degrees through the first lower gear 26, the two crank connecting rods 28 on the second lower gear 27 drive the two rocker arms 29 to slide along the horizontal sliding grooves 30, respectively, the displacement of the rocker arms 29 releases the constraint of the force reduction lever 31, the force reduction lever 31 rotates under the action of its own weight, and then the constraint of the unhooking lever 32 is released, after the constraint of the unhooking lever 32 is released, the arresting hook 33 rotates around the hook shaft 34 under the action of its own weight to hook the upper chord rod I-beam on the bottom mold 37 to stop slipping.

[0130] It should be noted that when the traction force disappears unexpectedly, danger occurs, and after the danger is handled, the crank connecting rod 28 needs to be manually removed, and then the rocker arm 29, the force reduction lever 31 and the arresting hook 33 are manually reset, and then the connecting rod crank connecting rod 28 is installed.

[0131] In the embodiment, the upper end of the rocker arm 29 and the second lower gear 27 are provided with mounting shafts, and the two ends of the crank connecting rod 28 are respectively provided with a sleeve for rotating around the mounting shafts.

[0132] The above is only the preferred embodiment of the present application, and does not limit the present application. Any simple modification, change and equivalent structural change of the above embodiment according to the technical essence of the present application are still within the protection scope of the technical solution of the present application.
