Description
Technical Field
[0001] The invention belongs to the technical field of lining trolleys, and in particular relates to a through-type trolley for inclined shaft lining. Background Art
[0002] The concrete lining of the inclined shaft of underground tunnels has always been a difficult point in hydropower construction. Due to environmental constraints, large-scale mechanical equipment cannot be put into use. Traditional small templates have always been used in combination with full-house scaffolding for construction, so the construction efficiency is low and there are great safety risks. The Chinese patent with the authorization announcement number CN 115182753B discloses an inclined shaft S-bend full-section lining template system and a lining construction method, which clarifies that the lining template system includes an upper curved section template system for constructing the upper curved section lining of the inclined shaft, an inclined straight section template system for constructing the inclined straight section lining of the inclined shaft, and a lower curved section template system for constructing the lower curved section lining of the inclined shaft. The upper curved section template system, the inclined straight section template system and the lower curved section template system are all spliced by multiple circular template splicing sections with gradually changing widths, and each of the circular template splicing sections includes two gradually changing width side templates and a top template and a bottom template respectively connected between the two ends of the two gradually changing width side templates. By adjusting the direction of the narrow end of the spliced section of the annular formwork, the lining of the upper curved section, the inclined straight section and the lower curved section of the inclined shaft can be constructed and formed in one go, which can eliminate the elastic changes of the slipform steel strands and eliminate the need for secondary processing. This can effectively improve construction efficiency, reduce construction safety risks, and effectively solve the problems of the inability to construct the upper and lower curved sections and the inability to construct the triangular areas of the inclined straight sections in conventional practices of inclined shaft lining and slipform construction.
[0003] In the process of lining construction using the S-bend full-section lining formwork system of the inclined shaft, when installing and disassembling the lining formwork, the top formwork, bottom formwork and width gradient side formwork need to be transported separately, and the installation direction of the width gradient side formwork needs to be adjusted according to the construction position of the inclined shaft. The traditional lining trolley cannot achieve this function. In addition, the inclined shaft is an underground large-slope inclined shaft, and safety assurance is the bottom line of the design work. When the traction force of the trolley disappears unexpectedly, there is a risk of the trolley sliding in the inclined shaft, which poses a great safety hazard. Therefore, it is necessary to propose a through-type trolley for inclined shaft lining, which can meet the requirements for disassembly and assembly of different shapes of formworks such as downward bend, inclined straight, and upward bend.

[0060] The front end of the trolley body 43 is provided with a traction lug 2 for connecting a hook of the traction mechanism, and the trolley body 43 is provided with a bottom mold lifting mechanism for lifting the bottom mold 37, a top mold mounting mechanism for installing the top mold 39, an operating platform 53 rotatably mounted on the trolley body 43, and a side mold mounting mechanism for installing the side mold in sequence from front to back. A leveling cylinder 55 for leveling the operating platform 53 is provided in the trolley body 43. The number of the side mold mounting mechanisms is two, and the two side mold mounting mechanisms are symmetrically arranged on both sides of the trolley body 43. The top mold mounting mechanism includes a top mold tray 47 for installing the top mold 39 and a jacking mechanism for driving the top mold tray 47 to rise and fall. Each of the side mold mounting mechanisms includes a rotating disk 52 for installing the side mold, a rotating driving member 51 for driving the rotating disk 52 to rotate, and a telescopic mechanism for driving the rotating driving member 51 and the rotating disk 52 to extend and retract together;
[0061] A traction rod 3 for installing a traction ear 2 is slidably inserted through the pulling beam 22 at the front end of the trolley body 43. The traction ear 2 is installed at the front end of the traction rod 3. The rear end of the traction rod 3 passes through the pulling beam 22 and is connected to a force transmission plate 4. A traction rod reset spring 5 is arranged between the force transmission plate 4 and the pulling beam 22. The traction rod reset spring 5 is sleeved on the traction rod 3. The rear end of the traction rod 3 is also provided with a force loss anti-slip mechanism.
[0062] In actual use, the running track of the trolley is set on the upper chord 38 of the bottom mold 37. Since there is a 6-meter track requirement before and after the warehouse number, 4 bottom molds 37 are added at the front end and a secondary track trolley 41 is added at the rear end to solve the problem. When the trolley is placed at the rear end of the warehouse number and installed in place, the track on the top of the secondary track trolley 41 is connected to the track on the bottom mold 37 to form an integral track.
[0063] During specific implementation, the auxiliary rail trolley 41 is connected to the trolley chassis 42 through pins, and the auxiliary rail trolley 41 is connected to the bottom mold 37 through pins.
[0064] It should be noted that by arranging a traction ear 2 at the front end of the trolley body 43, and arranging a bottom mold lifting mechanism, a top mold mounting mechanism, an operating platform 53 and a side mold mounting mechanism on the trolley body 43 in sequence from front to back, the functional division of the trolley body 43 can be realized, and the trolley body 43 is divided into a lifting and traction area, a top mold functional area, a trolley operating area and a side mold functional area, thereby realizing the transportation and disassembly of the top mold, bottom mold and side mold, which is easy to operate and can effectively improve the efficiency of template disassembly and assembly.
[0065] During specific implementation, a double-linked pulley group is hung on the front traction lifting eye 2, which forms a traction system with the fixed pulley group and winch arranged at the waist of the tunnel to provide upward traction for the trolley.
[0066] It should be noted that by rotatably installing the operating platform 53 on the trolley body 43 and arranging a leveling cylinder 55 in the trolley body 43 to adjust the rotation angle of the operating platform 53, the operating platform 53 can be rotated and leveled at different angles of the trolley in the inclined shaft to facilitate the operator's operation.

[0068] During specific implementation, since the longitudinal section of the tunnel is "S"-shaped, the existence of the trolley wheel track makes the motion trajectory of the midpoint of the trolley not coincide with the axis of the tunnel during the longitudinal movement. A group of centering components are respectively arranged on the left and right sides of the trolley chassis 42, and the offset of the trolley body 43 is compensated by controlling the lifting of the centering components, thereby ensuring the safety and stability of the trolley operation.

Through the action of the traction rod reset spring 5, the force-loss anti-skid mechanism can be triggered by the traction system. When the traction force disappears unexpectedly, the traction rod 3 is reset under the action of the traction rod reset spring 5, so that the force-loss anti-skid mechanism is actuated to lock the position of the trolley, which can effectively reduce the risk of the trolley slipping in the inclined shaft.

The lower end of each of the guide uprights 58 is slidably penetrated on the trolley chassis 42, and the upper end of each of the guide uprights 58 is fixed to the bottom of the trolley body 43. The cylinder body of the centering hydraulic cylinder 57 is fixed on the trolley chassis 42, and the piston rod end of the centering hydraulic cylinder 57 is connected to the bottom of the trolley body 43.
[0091] In specific implementation, the structure of the trolley chassis 42 is similar to that of the trolley body 43 , the height of the trolley chassis 42 is smaller than that of the trolley body 43 , and a guide upright rod 58 is slidably inserted into the upper end of the vertical rod section of the trolley chassis 42 .
[0092] In specific implementation, the cylinder body of the centering hydraulic cylinder 57 is fixed on the bottom longitudinal rod of the trolley chassis 42 , and the piston rod end of the centering hydraulic cylinder 57 passes through the top longitudinal rod of the trolley chassis 42 from bottom to top and is hinged to the bottom of the trolley body 43 .
[0093] During specific implementation, the centering hydraulic cylinder 57 and the guide upright rod 58 are parallel to the top mold lifting hydraulic cylinder 46.

A crank connecting rod 28 is rotatably mounted on the upper end of the rocker arm 29, and the other end of the crank connecting rod 28 is eccentrically hinged on the second lower gear 27.
[0107] During specific implementation, the rear end of the force transmission rod 23 is slidably inserted into the first vertical rectangular frame 431 of the trolley body 43, the force transmission rod 23 is coaxially arranged with the traction rod 3, the transmission shaft 25 is perpendicular to the force transmission rod 23, and the rack and pinion transmission mechanism 24 includes an upper gear 241 fixed to the upper end of the transmission shaft 25 and a rack 242 fixed on the force transmission rod 23 and meshing with the upper gear 241.

[0109] During specific implementation, a plurality of ear plates for rotatably mounting the transmission shaft 25 are provided from top to bottom at the front end of the trolley body 43 .
[0110] During specific implementation, a gear mounting plate 36 for mounting the gear set 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 horizontal slide groove 30 is perpendicular to the transmission shaft 25.
[0111] During 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 against.

[0113] The pump station and control valve are installed on the operating platform 53 in the middle of the trolley. To facilitate observation and operation, the control valves are arranged around the platform guardrail according to the controlled parts. The hydraulic pipeline on the trolley is fixed to the trolley body with a seamless steel pipe with an inner diameter of φ10mm through a pipeline clamp; the beginning of the pipeline is connected to the control valve interface through a high-pressure rubber hose. Since the operating platform will be rotated and leveled according to the change of the slope of the inclined shaft, a certain amount of surplus needs to be reserved for the connecting hose. The end of the pipeline is connected to the actuator interface through a card joint;
[0114] The control valve adopts a manual three-position four-way reversing valve. In order to improve the action accuracy of the actuator, the valve is connected in series;
[0115] Except for the rotary mechanism, other control circuits belong to the one-control-multiple situation, that is, one reversing valve controls four hydraulic cylinders; therefore, four manual ball valves are connected in parallel at the outlet of the reversing valve, and each ball valve controls one hydraulic cylinder; in this way, the advance and retreat of one cylinder can be controlled separately when high-precision hole alignment is required; in addition, due to the different friction forces of each cylinder, there is a phenomenon of asynchrony; the synchronization problem can be manually adjusted by switching the ball valve separately;
[0116] Hydraulic cylinders basically work under load. To prevent the hydraulic cylinders from falling back and nodding, each cylinder is equipped with a hydraulic lock to lock it.
[0117] like Fig. 9 As shown, in specific implementation, when the template is transported by the present invention, the following steps are specifically included:
[0118] Step 1: Pin the trolley chassis 42 and the auxiliary rail trolley 41 to form an integral trolley, and add 4 bottom molds 37 in a bin number at the front end of the bin number where the concrete lining has been completed;
[0119] Step 2: The integrated trolley is towed to the rear end of the warehouse where the concrete lining has been completed by the traction system, and then the front end of the auxiliary rail trolley 41 is pinned to the bottom mold 37 of a ring of the rear end of the warehouse to be constructed, and the connecting pin between the trolley chassis 42 and the auxiliary rail trolley 41 is removed;
[0120] Step 3: Use the traction system to tow the trolley chassis 42 and the trolley body 43 to move as a whole, and remove the four-ring top formwork 39 and side formwork in the warehouse number where the concrete lining has been completed from back to front, and then transfer and install them to the next warehouse number; then remove the remaining top formwork 39, side formwork and bottom formwork 37 in the warehouse number where the concrete lining has been completed from back to front, and transfer and install them to the next warehouse number.
[0121] In step three, when the formwork is removed, transported and installed, it is removed, transported and installed ring by ring, that is, after removing the top form 39 and side form in one ring, the trolley passes through the center of the form in the warehouse number where the concrete lining has been completed, and transports the removed top form 39 and side form to the next warehouse number and installs them, then the trolley chassis 42 and the trolley body 43 are moved as a whole to the warehouse number where the concrete lining has been completed through the traction system, and the top form 39 and side form of the next ring are removed, and so on; when the top form 39 and side form of the four rings are removed, transported and installed, when the top form 39 and side form of the fifth ring are removed, the bottom form 37 in the first ring is removed simultaneously, and so on, the removal of all the top form 39 and side form in the warehouse number where the concrete lining has been completed is completed; then the remaining bottom form 37 in the warehouse number where the concrete lining has been completed is removed, transported and installed from back to front;
[0122] When removing the top mold 39 and the side molds, first remove the top mold 39, then remove the two side molds, and then transfer the top mold 39 and the side molds synchronously. When installing the top mold 39 and the side molds, first install the top mold 39, and then install the side molds;
[0123] When removing the top mold 39, the piston rods of the four top mold lifting hydraulic cylinders 46 extend and drive the four guide columns 45 to slide upward, thereby causing the top mold tray 47 to rise to below the top mold 39, and then the top mold 39 is connected to the top mold tray 47 by bolts, and then the connection between the top mold 39 and the side molds is removed, and the piston rods of the top mold lifting hydraulic cylinders 46 are controlled to retract, driving the top mold 39 to descend until the top mold 39 is separated from the side molds, and the removal of the top mold 39 is completed; otherwise, the top mold 39 is installed;
[0124] When removing the side mold, the piston rods of the side mold rotating hydraulic cylinders 49 on both sides of the trolley body 43 extend and drive the guide crossbar 48 to slide outward, thereby moving the two side brackets 50 to the two side molds on both sides respectively, and connecting the two side molds to the two side brackets 50 respectively by bolts, and then removing the connection between the side mold and the bottom mold 37, and controlling the piston rod of the side mold rotating hydraulic cylinder 49 to retract, driving the two side molds to be recovered, until the side molds are separated from the bottom mold 37, and the removal of the side mold is completed;
[0125] When installing the side mold, when the rotation direction of the side mold needs to be changed, the side mold is rotated 180 degrees through the rotary drive member 51, and then the piston rod of the side mold rotation hydraulic cylinder 49 is controlled to extend to install the side mold in place;
[0126] When the bottom mold 37 is removed, the bottom mold 37 is lifted by setting a fall chain on the lifting lug 44; when the bottom mold 37 is installed, the bottom mold 37 is lowered into place by the fall chain.
[0127] In specific implementation, during the reverse transportation of the template, when the traction force disappears unexpectedly, the traction rod 3 moves backward and resets under the action of the traction rod reset spring 5, thereby completing the locking of the wire rope locking mechanism and the release hook mechanism to prevent the trolley from slipping;
[0128] The wire rope locking mechanism prevents slipping: the force transmission plate 4 fixed on the traction rod 3 moves backward, and the force transmission vertical shaft 15 on the force transmission plate 4 drives the lever 13 to rotate through the connecting rod 14. After the lever 13 rotates, the limit of the fork 12 is cancelled. Under the action of the rope clamping return spring 19, the fork 12 drives the two rope clamping wedges 11 to move into the rope clamping groove 9 and clamp the safety wire rope 1 to prevent the trolley from slipping;
[0129] Anti-slip of the release hook mechanism: the force transmission rod 23 fixed at the rear end of the traction rod 3 moves backward, and under the transmission of the gear rack transmission mechanism 24, the transmission shaft 25 rotates 90 degrees, and then drives the second lower gear 27 to rotate 90 degrees through the first lower gear 26, and the two crank connecting rods 28 on the second lower gear 27 respectively drive the two rocker arms 29 to slide along the transverse slide groove 30, and the displacement of the rocker arm 29 releases the constraint on the force reducing lever 31, and the force reducing lever 31 rotates under the action of its own weight, thereby releasing the constraint on the unhooking lever 32. After the constraint of the unhooking lever 32 is released, the anti-fall hook 33 rotates around the hook shaft 34 under the action of its own weight, thereby hooking the upper chord I-beam on the bottom mold 37 to prevent slipping.
[0130] It should be noted that when the traction force disappears unexpectedly, a dangerous situation occurs, and after the dangerous situation is dealt with, the crank connecting rod 28 needs to be manually removed, and then the rocker arm 29, the force reducing lever 31 and the anti-fall hook 33 are manually reset, and then the connecting rod crank connecting rod 28 is installed.
[0131] In a specific implementation, a mounting shaft is provided on the upper end of the rocker arm 29 and the second lower gear 27 , and a sleeve rotatably sleeved on the mounting shaft is provided on each of the two ends of the crank connecting rod 28 .
[0132] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
