[0016] 1. The rotary tunnel cloth hanging trolley can rotate with the rotating mechanism through the supporting mechanism to support the waterproof cloth and lay the waterproof cloth along the top wall of the tunnel. The waterproof cloth can be quickly unfolded. The waterproof cloth and geotextile can be rolled up by the reel and unfolded during the laying process. When used in combination with the unfolding drum, the cloth can be tightened while the reel releases the cloth along the tunnel wall to ensure the contact and tightening effect between the cloth and the tunnel wall, which is beneficial to the subsequent fixing operation of the waterproof cloth. Through the stage, when a slide rail is provided on it, it can be used to install waterproof cloth cutting tools, gasket installers and measuring components, which is beneficial to the realization of waterproof construction operations.

[0017] 2. This rotary tunnel cloth hanging trolley can generate a reset elastic force through a reset spring to push the shock-absorbing rod and even the reel and unfolding tube thereon to move upward, ensuring that the waterproof cloth is always pressed against the tunnel wall, avoiding the unevenness of the tunnel wall, which causes a large gap between the waterproof cloth and the tunnel wall, affecting the actual construction. By combining the guide rod and the movable column, the guide rod can move up and down along the movable column under force, thereby adjusting the height of the support column and even the curved frame up and down, which is beneficial to the actual construction operation. The branch cylinder can produce a telescopic movement effect and provide torque to lift or lower the curved frame and even the support column.

[0018] 3. The rotary tunnel cloth hanging trolley can be rotated by an external power component through a rotating shaft, and with the help of the connection effect of the connecting rod, it can drive the slide tube and the auxiliary oil cylinder thereon to rotate, thereby changing the angle or position of the support mechanism. Especially when the cloth hanging trolley is in the middle position of the tunnel, it can quickly drive the auxiliary oil cylinder and its support mechanism to rotate, so as to quickly construct the waterproof cloth, etc., which is beneficial to improve construction efficiency. Moreover, while quickly laying the waterproof cloth, there is no need to rely on a large area of ​​the trolley body to support the waterproof cloth, etc., which can reduce the volume of the trolley body, facilitate tunnel construction, and thereby reduce production costs.

[0019] 4. This rotary tunnel cloth hanging trolley, through the support tube and used in combination with the limit slot, can provide limit support to the slide tube when it rotates, increase the force surface, and thus improve the structural stability. Through the scaffolding, a supporting plane can be formed, which is convenient for storing some tools required for construction, and combined with the scaffolding groove, it can be interference fit with the scaffolding to achieve a clamping and fixing effect, which is beneficial to improve the structural stability while facilitating disassembly and installation.

[0030] like Figure 1-6As shown, the rotary tunnel cloth hanging trolley of this embodiment includes a trolley body 1 and a curved frame 6 above the trolley body 1. A steel truss 12 is installed at the bottom end of the curved frame 6. The steel truss 12 is composed of steel materials and can be used for support required for general construction. A control box 13 is installed at the bottom end of the trolley body 1. The control box 13 includes a control circuit box body, a hydraulic control component, an oil tank and other components, which can control the entire tunnel trolley as a whole. A supporting mechanism is installed between the trolley body 1 and the curved frame 6. The supporting mechanism uses the trolley body 1 as a supporting surface. The curved frame 6 is supported or lifted up and down. A rotating mechanism is movably installed on the supporting mechanism, and the rotating mechanism is connected to an external motor by means of a belt drive. The belt drive can drive the rotating mechanism to move, and the transmission of vibration force can be reduced by means of the characteristics of the belt. A supporting mechanism is movably installed on the rotating mechanism; the supporting mechanism includes a sub-cylinder 7 and a triangular bracket 26. The sub-cylinder 7 is movably installed on the rotating mechanism. When actually used, it can be affected by the rotating mechanism and rotate around a specific axis position. The sub-cylinder 7 is connected to the control box 1 through an explosion-proof oil pipe. 3 is connected to the internal hydraulic control component, which can produce a telescopic effect and push the upper component to perform telescopic movement. The triangular bracket 26 is fixedly installed at the end of the telescopic rod of the auxiliary oil cylinder 7. The two ends of the triangular bracket 26 are arranged at an angle, and combined with the telescopic rod of the auxiliary oil cylinder 7 to form a "Y"-shaped component. A reel 23 is installed at one end of the triangular bracket 26 with the help of a shock-absorbing component. The reel 23 can rotate around the pin shaft, and the shaft diameter of the reel 23 is small, so that the waterproof geotextile can be rolled up and the waterproof geotextile can be unfolded during the laying process. The other end of the triangular bracket 26 is installed with a reel 23 with the help of a shock-absorbing component. The shock-absorbing component is equipped with an unfolding cylinder 24, which is a cylindrical drum with a large diameter and is slightly higher than the reel 23. After the waterproof cloth on the reel 23 is unfolded, the waterproof cloth can be tightened to ensure that the waterproof cloth is in contact with the tunnel wall. A loading platform 21 is installed at the end of the telescopic rod of the auxiliary oil cylinder 7 on one side of the triangular bracket 26. The loading platform 21 is located below the reel 23 and extends horizontally. If a slide rail is provided on it, such as an electromagnetic slide rail, it can be used to install waterproof cloth cutting tools, gasket installers and measuring components, etc., which is beneficial to the realization of waterproof construction operations.

[0031] Specifically, the supporting mechanism includes a main oil cylinder 5 and a supporting column 8. A movable platform 4 is arranged at the top of the trolley body 1. The movable platform 4 is an elongated supporting platform, and the main oil cylinder 5 is installed at the top of the movable platform 4. The main oil cylinder 5 can use a general large hydraulic cylinder, which can accept the external oil pressure to produce telescopic movement, support the upper parts and other operations. A movable column 10 is installed at the top of the telescopic rod of the main oil cylinder 5. The interior of the top of the movable column 10 is hollow, which can transmit the supporting force generated by the main oil cylinder 5, and the supporting column 8 is installed at the top of the movable column 10 to transmit the supporting force. The top of the support column 8 is connected to the bottom end of the curved frame 6 to produce a supporting effect.

[0032] Furthermore, a guide rod 81 is installed at the bottom end of the support column 8. The surface of the guide rod 81 is smooth. The guide rod 81 is movably extended to the inside of the movable column 10, and the two are in smooth contact. During actual use, the guide rod 81 can be forced to move up and down along the inner wall of the movable column 10, and a branch cylinder 9 is installed on the surface of the movable column 10. The branch cylinder 9 is controlled by a hydraulic control component and can generate a telescopic torque under the action of hydraulic pressure. The end of the branch cylinder 9 extends to the bottom end of the curved frame 6, which can apply an upward force to the curved frame 6, thereby causing the guide rod 81 to move up and down.

[0033] Furthermore, the rotating mechanism includes a rotating shaft 18 and a support tube 11. The rotating shaft 18 is movably installed between the supporting mechanisms, and is actually installed between two groups of movable columns 10 with the help of a bearing seat, that is, it is matched with two groups of master cylinders 5. A pulley component is installed at one end of the rotating shaft 18, which can be acted upon by an external motor to produce a rotating effect on the rotating shaft 18. The surface of the rotating shaft 18 is smooth and sleeved with a shaft sleeve 20. The two are fixedly connected with a pin. The surface of the shaft sleeve 20 is radially installed with a connecting rod 19, which plays a certain supporting effect, and the support tube 11 is concentric along the axis of the rotating shaft 18. The support tube 11 is sleeved on the outside of the connecting rod 19, and the two are not directly fixedly connected. In fact, the two ends of the support tube 11 are respectively fixedly mounted on the movable column 10. When necessary, the inner wall of the support tube 11 and the inner wall of the rotating shaft 18 are smoothly connected through a sliding sleeve to play a supporting role. The bottom end of the auxiliary oil cylinder 7 is installed with a slide tube 15. The slide tube 15 is an annular metal component as a whole, and the slide tube 15 is smoothly sleeved on the surface of the support tube 11. The two are in smooth contact. In fact, the support tube 11 can provide limited support for the slide tube 15, and then provide a certain limited support effect on the auxiliary oil cylinder 7.

[0034] Furthermore, an annular groove 16 is provided on the surface of the support tube 11, and the annular groove 16 is connected inside and outside, so that the support tube 11 is in a disconnected state, and the connecting rod 19 is connected to the slide tube 15 through the annular groove 16, that is, an indirect connection between the rotating shaft 18 and the slide tube 15 is realized, and the surfaces of the support tube 11 on both sides of the annular groove 16 are provided with limiting grooves 17, and the limiting grooves 17 are annular I-shaped groove components, and there are sliding strips on the inner wall of the slide tube 15 that cooperate with the limiting grooves 17, so that the slide tube 15 can perform limiting movement along the limiting grooves 17 when rotating, and generate limiting torque, thereby improving the connection effect between the support tube 11 and the slide tube 15 and enhancing the structural stability of the auxiliary oil cylinder 7 when moving.

[0035] Furthermore, the shock-absorbing component includes a return spring 22 and a shock-absorbing rod 25. The shock-absorbing rod 25 is respectively installed at the connection between the winding drum 23 and the triangular bracket 26 and the unfolding drum 24 and the triangular bracket 26. It is a rod with different widths at both ends. One end of the shock-absorbing rod 25 slides and extends to the inside of the triangular bracket 26 with the help of a slide groove, and is limited by a limit block of a general slide groove. The return spring 22 is installed in the gap between the shock-absorbing rod 25 and the triangular bracket 26. A small part of the actual return spring 22 is sleeved on the surface of the shock-absorbing rod 25, and most of it is fixedly installed inside the triangular bracket 26, thereby generating a return elastic force for the shock-absorbing rod 25. In actual use, the return spring 22 pushes the shock-absorbing rod 25 and even the winding drum 23 and the unfolding drum 24 thereon to move upward, ensuring that the waterproof cloth is always pressed against the tunnel wall, avoiding a large gap between the waterproof cloth and the tunnel wall when the tunnel wall is uneven, thereby affecting actual construction.

[0036] Furthermore, both side surfaces of the trolley body 1 are installed with a mounting groove 14, which is a flat metal ring connected up and down, and a mounting frame 3 is installed on the surface of the mounting groove 14. One end of the actual mounting frame 3 is a vertical cone, which can be inserted into the mounting groove 14 to achieve an interference fit installation method, and the mounting frame 3 extends to one side to form a supporting plane, which is convenient for supporting specific tools, etc., and a support rod 2 is hingedly installed on the surface of the trolley body 1 below the mounting groove 14, and the end of the support rod 2 extends obliquely upward to the surface of the mounting frame 3, thereby forming a triangular support to provide structural stability for the mounting frame 3.

[0037] The method of use of this embodiment is as follows: in order to lay waterproof cloth or geotextile on the inner wall of the tunnel, with the help of external pushing equipment or manual labor, in the case where there is a pulley on the trolley body 1, the entire cloth-hanging trolley is pushed into the tunnel along a specific track, and at this time the main cylinder 5 and the auxiliary cylinder 7 are all in a retracted state. If it is necessary to lay the waterproof cloth or geotextile to be laid starting from the wall surface at the bottom end of the tunnel in a clockwise direction, the auxiliary cylinder 7 is tilted to one side and is in the lowest position, and the waterproof cloth or geotextile to be laid is rolled up on the surface of the drum 23, and the cloth hanging operation is started. One end of the waterproof cloth rolled up on the surface of the drum 23 is manually torn off, and flattened upward on the unfolding drum 24, and then pulled downward to fix one end of the waterproof cloth on the inner wall at the bottom end of the tunnel, and the loading platform 21 is equipped with specific required tools, such as a nail gun, a gasket machine and a cutting machine. etc., for realizing operations such as cutting or fixing of waterproof cloth, and the electric tool needs to be electrically connected to the control box 13 through a wire. The entire trolley body 1 is in the center of the tunnel section. Under the control of the control box 13, the main oil cylinder 5 supplies oil and extends, pushing the movable column 10 and the components thereon to rise and move to a suitable position. Because the support effect of the curved frame 6 is not required, the auxiliary oil cylinder 7 can supply oil and extend, so that the unfolding cylinder 24 and the waterproof cloth on the winding drum 23 are respectively in contact with the tunnel wall surface, and the motor is started in stages to drive the rotating shaft 18 to rotate a certain angle. At this time, the shaft sleeve 20 and the connecting rod 19 rotate synchronously with the rotating shaft 18. When the connecting rod 19 rotates, it can drive the slide cylinder 15 and even the entire auxiliary oil cylinder 7 to rotate synchronously, and is limited and supported by the limit slot 17. At the same time , under the torque of the return spring 22, the unfolding cylinder 24 moves upward, so that the waterproof cloth on it is always pressed against the tunnel wall. After rotating a certain angle, that is, the unfolding cylinder 24 rolls a certain angle on the tunnel wall, and presses the waterproof cloth tightly, under the pulling force, the waterproof cloth on the reel 23 is unfolded and continuously spread on the tunnel wall by the unfolding cylinder 24. The gasket machine on the loading platform 21 pushes the gasket on the waterproof cloth, and then the nail gun is used to shoot nails, thereby achieving the fixing effect of the waterproof cloth. In order to increase the actual fixing effect, two sets of slide cylinders 15 and auxiliary oil cylinders 7 can be installed on the support cylinder 11, that is, two sets of support mechanisms are installed, one set can roll up the waterproof cloth, and the other set is unloaded, and there are two loading platforms 21 and fixing components, which act on the left and right side surface edges of the waterproof cloth respectively. It plays the role of fixed support. After the fixing is completed, the motor continues to drive the rotating shaft 18 to rotate clockwise by a certain angle, and the unfolding cylinder 24 and even the winding cylinder 23 move a certain angle to continue the operation of fixing the waterproof cloth. After the fixing is completed in sequence, the waterproof cloth moves from the left side to the right side along the inner wall of the tunnel to complete the laying operation of the entire tunnel. The construction period is short, especially when there are irregular surfaces such as certain transverse bumps on the inner wall of the tunnel. Due to the action of the reset spring 22, such as when there is a concave position, the reset elastic force of the reset spring 22 pushes the unfolding cylinder 24 upward and presses the waterproof cloth tightly, so that the waterproof cloth is always in contact with the tunnel wall to ensure sufficient waterproof effect. After the construction is completed, when manual operation is required, such as maintenance, the auxiliary oil cylinder 7 can be retracted, and manual climbing can be performed on the steel truss 12.Continue to supply pressure to the main oil cylinder 5 to drive the curved frame 6 upward as a whole, which is conducive to shortening the distance between the staff and the tunnel wall.

[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
