Description

Technical Field

[0001] The present invention relates to the technical field of waterproofing technology for tunnel construction, and specifically relates to a waterproof cloth laying device for tunnel construction. Background Art

[0002] When laying a waterproof cloth during tunnel construction, a waterproof cloth laying trolley is required. When the rotating trolley lays the waterproof cloth along the curvature of the tunnel inner wall on the lining layer, the waterproof cloth needs to be fixed to the primary lining surface by nails. The above operations are usually carried out manually. The operator stands on the electric side platform and controls the lifting of the electric side platform through a screw jack. Thus, the operator manually holds a pneumatic nail gun to nail and fix the waterproof cloth at different positions. This method has a high manual operation intensity, and the operator needs to continuously change the operation position, making the laying process of the waterproof cloth more cumbersome. Moreover, manual reinforcement requires auxiliary measurement, further increasing the work intensity and prone to errors, resulting in insufficient tightness of the waterproof cloth fitting.

Detailed implementation manners

[0075] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0076] As Figures 1 to 3 shown, a waterproof cloth laying device for tunnel construction includes a waterproof cloth laying and installation frame 1, a roll clamping component 3, a tensioning and fitting component 4 and a waterproof cloth roll 5;

[0077] The waterproof cloth laying and installing frame 1 is installed on the compound track drive system of the tunnel jumbo;

[0078] Both the roll clamping assembly 3 and the tensioning and fitting assembly 4 are installed on the waterproof cloth laying and installing frame 1;

[0079] The waterproof cloth roll 5 is arranged on the roll clamping assembly 3;

[0080] It further includes an adjustable nail shooting assembly 2 installed on the waterproof cloth laying and installing frame 1;

[0081] The adjustable nail shooting assembly 2 includes a pneumatic nail gun 2a capable of automatically shooting nails, and the pneumatic nail gun 2a is arranged between the roll clamping assembly 3 and the tensioning and fitting assembly 4 in an angle-adjustable manner.

[0082] The waterproof cloth roll 5 is automatically clamped on the waterproof cloth laying and installing frame 1 by the roll clamping assembly 3 and moves along the inner wall of the tunnel following the compound track drive system. During the movement, the waterproof cloth is tensioned and laid on the primary lining surface by the tensioning and fitting assembly 4. During the laying process, the pneumatic nail gun 2a in the adjustable nail shooting assembly 2 moves between the roll clamping assembly 3 and the tensioning and fitting assembly 4, and the pneumatic nail gun 2a drives the nails into the tunnel primary lining surface where the waterproof cloth has been laid, realizing the function of automatically shooting and fixing nails during the waterproof cloth laying process, improving the installation progress of the waterproof cloth, improving work efficiency, reducing the labor intensity of workers, and during the reciprocating laying process of the waterproof cloth, automatically adjusting the relative position of the pneumatic nail gun 2a and the tensioning and fitting assembly 4 according to the laying sequence, and changing the angle of the pneumatic nail gun 2a on the waterproof cloth laying and installing frame 1 according to the different curvatures at different positions of the tunnel, so as to accurately drive the nails.

[0083] Such as Figures 8 to 11 The adjustable nail shooting assembly 2 shown also includes a vertical displacement driving mechanism 2b, an angle deflection driving mechanism 2c, a horizontal mounting frame 2d, a horizontal displacement driving mechanism 2e, and a horizontal pushing mechanism 2f;

[0084] There are two groups of both the vertical displacement driving mechanism 2b and the angle deflection driving mechanism 2c, and the two groups of vertical displacement driving mechanisms 2b and angle deflection driving mechanisms 2c are respectively located at both ends of the waterproof cloth laying and installing frame 1;

[0085] The vertical displacement driving mechanism 2b is fixedly installed on the waterproof cloth laying and installing frame 1, and the output direction of the vertical displacement driving mechanism 2b is consistent with the width direction of the waterproof cloth laying and installing frame 1;

[0086] The horizontal pushing mechanism 2f is installed on the output end of the vertical displacement driving mechanism 2b, the output direction of the horizontal pushing mechanism 2f is perpendicular to the length direction of the waterproof cloth laying and installing frame 1, and the output direction of the horizontal pushing mechanism 2f points to the side close to the inner wall of the tunnel;

[0087] The angle deflection driving mechanism 2c is installed at the output end of the horizontal pushing mechanism 2f;

[0088] The horizontal mounting frame 2d is installed between two sets of angle deflection driving mechanisms 2c, and the horizontal mounting frame 2d is in transmission connection with the angle deflection driving mechanism 2c;

[0089] The horizontal displacement driving mechanism 2e is horizontally installed on the horizontal mounting frame 2d;

[0090] The pneumatic nail gun 2a is in transmission connection with the horizontal displacement driving mechanism 2e.

[0091] Through the vertical displacement driving mechanism 2b, the adjustable nail shooting assembly 2 can be driven to displace integrally on the waterproof cloth laying and mounting frame 1 along the direction perpendicular to the length of the waterproof cloth laying and mounting frame 1, that is, the position of the adjustable nail shooting assembly 2 between the roll clamping assembly 3 and the tensioning and fitting assembly 4 can be adjusted. When the waterproof cloth on one of the waterproof cloth rolls 5 is being laid, one end of the waterproof cloth is wound around the waterproof cloth roll 5, and the other end passes through the tensioning and fitting assembly 4 and is hung in the tunnel. The adjustable nail shooting assembly 2 is displaced by the vertical displacement driving mechanism 2b to the part where the waterproof cloth has passed through the tensioning and fitting assembly 4 and is fitted, and the pneumatic nail gun 2a automatically nails the nails on the waterproof cloth to complete the hanging of the waterproof cloth.

[0092] During the hanging installation, through the output of the horizontal pushing mechanism 2f, the angle deflection driving mechanism 2c and the horizontal mounting frame 2d are pushed outwards, so that the pneumatic nail gun 2a installed on the horizontal mounting frame 2d reaches the working position. The angle deflection driving mechanism 2c outputs, and according to the fixed change of the position in the tunnel, the angle of the pneumatic nail gun 2a relative to the waterproof cloth laying and mounting frame 1 is changed, so that the nails can be driven into the waterproof cloth at the best angle. The horizontal displacement driving mechanism 2e outputs to drive the pneumatic nail gun 2a to move along the length direction of the waterproof cloth laying and mounting frame 1, that is, the pneumatic nail gun 2a can automatically move along the width direction of the waterproof cloth to adjust the density of the nails according to requirements.

[0093] The angle deflection driving mechanism 2c includes a first connecting rod 2c1, a second connecting rod 2c2 and an electric push rod 2c3;

[0094] Both the first connecting rod 2c1 and the second connecting rod 2c2 are located between the horizontal mounting frame 2d and the waterproof cloth laying and mounting frame 1;

[0095] One end of the first connecting rod 2c1 is fixedly connected to the side wall of the horizontal pushing mechanism 2f;

[0096] The second connecting rod 2c2 is located between the horizontal mounting frame 2d and the first connecting rod 2c1, one end of the second connecting rod 2c2 is hinged to the end of the first connecting rod 2c1 away from the waterproof cloth laying mounting frame 1, and the other end of the second connecting rod 2c2 is fixedly connected to the side wall of the horizontal mounting frame 2d;

[0097] The electric push rod 2c3 is rotatably connected to the horizontal pushing mechanism 2f through a mounting seat, and the output end of the electric push rod 2c3 is rotatably connected to the side wall of one end of the second connecting rod 2c2 close to the horizontal mounting frame 2d.

[0098] The angle of the pneumatic nail gun 2a relative to the waterproof cloth laying installation frame 1 can be adjusted through the angle deflection driving mechanism 2c. When the angle deflection driving mechanism 2c is working, the second connecting rod 2c2 hinged thereto is driven to move through the output of the electric push rod 2c3. The second connecting rod 2c2 deflects around the hinged end with the first connecting rod 2c1, thereby changing the angle between the pneumatic nail gun 2a and the waterproof cloth laying installation frame 1. When the angle deflection driving mechanism 2c is working, the vertical displacement driving mechanism 2b is controlled by the controller to output synchronously, so that the pneumatic nail gun 2a always remains at the predetermined output position, that is, only the nail shooting angle is changed, but the nail shooting position is not changed, thereby improving the linkage.

[0099] There are two pneumatic nail guns 2a;

[0100] Two pneumatic nail guns 2a are respectively installed on both sides of the horizontal mounting frame 2d, and the two pneumatic nail guns 2a are both transmission-connected to the horizontal displacement driving mechanism 2e.

[0101] Providing two pneumatic nail guns 2a can improve the firing efficiency of a single layer of nails. At the same time, the relative positions of the two pneumatic nail guns 2a on the width of the waterproof cloth can be synchronously adjusted through the horizontal displacement drive mechanism 2e. The firing position of the pneumatic nail gun 2a can be adjusted according to actual needs, which improves efficiency while having autonomous adjustment capabilities. Compared with installing multiple pneumatic nail guns 2a at fixed positions, it has better actual working effects.

[0102] The horizontal displacement driving mechanism 2e includes a first rotation driver 2e1, a bidirectional threaded rod 2e2 and a threaded seat 2e3;

[0103] The first rotary driver 2e1 is mounted on one end of the horizontal mounting frame 2d;

[0104] The bidirectional threaded rod 2e2 is horizontally installed in the horizontal mounting frame 2d, and the two ends of the bidirectional threaded rod 2e2 are respectively axially connected to the two ends of the horizontal mounting frame 2d;

[0105] The output end of the first rotary driver 2e1 is transmission-connected to one end of the bidirectional threaded rod 2e2;

[0106] There are two threaded seats 2e3, which are symmetrically arranged at the two ends of the bidirectional threaded rod 2e2, and the threaded seats 2e3 are threadedly connected with the bidirectional threaded rod 2e2;

[0107] The two pneumatic nail guns 2a are fixedly mounted on the two threaded seats 2e3 respectively.

[0108] The horizontal displacement driving mechanism 2e can drive two pneumatic nail guns 2a to move along the width direction of the waterproof cloth. The output of the first rotation driver 2e1 drives the bidirectional threaded rod 2e2 to rotate. When rotating, the bidirectional threaded rod 2e2 drives the two threaded seats 2e3 threadedly connected to it to move toward or oppositely, thereby driving the two pneumatic nail guns 2a fixedly installed on the threaded seats 2e3 to move synchronously, thereby realizing the horizontal displacement driving function of the pneumatic nail guns 2a.

[0109] like Figures 4 to 7 The waterproof cloth laying installation frame 1 shown includes a first installation plate 1a, a transmission seat 1b and a second installation plate 1c;

[0110] The transmission seat 1b and the second mounting plate 1c are each provided with two;

[0111] Two transmission seats 1b are installed at both ends of the first mounting plate 1a, and the first mounting plate 1a is connected to the compound track transmission system through the transmission seats 1b;

[0112] The two second mounting plates 1c are respectively located at the two ends of the first mounting plate 1a and on the same side of the first mounting plate 1a. The length direction of the second mounting plates 1c is perpendicular to the length direction of the first mounting plate 1a. The length direction of the first mounting plate 1a is consistent with the tunnel travel direction.

[0113] There are two groups of roller clamping assemblies 3, which are respectively located at one end of the two second mounting plates 1c away from the first mounting plate 1a. The roller clamping assemblies 3 include a shaft connection seat 3a, a rotating bracket 3b and an end clamping mechanism 3c.

[0114] The shaft connection seat 3a is arranged at one end of the second mounting plate 1c away from the first mounting plate 1a, and the axis direction of the shaft connection seat 3a is consistent with the length direction of the first mounting plate 1a;

[0115] The rotating bracket 3b is rotatably mounted on the second mounting plate 1c through the shaft connection seat 3a, and the middle part of the rotating bracket 3b is connected to the shaft connection seat 3a;

[0116] The length of the rotating bracket 3b is smaller than the length of the first mounting plate 1a, and the rotating bracket 3b can rotate on the first mounting plate 1a around the axis of the shaft seat 3a;

[0117] There are two end clamping mechanisms 3c, which are respectively installed at both ends of the rotating bracket 3b. The symmetrically arranged end clamping mechanisms 3c in the two sets of roll clamping assemblies 3 are respectively used to clamp both ends of the same waterproof cloth roll 5, that is, the roll clamping assembly 3 can clamp two sets of waterproof cloth rolls 5 at the same time.

[0118] The two transmission seats 1b are connected to the compound track transmission system, so that the first mounting plate 1a and the load carried thereon can follow the output end of the compound track transmission system to reciprocate in an arc, realizing the displacement operation of the waterproof cloth laying. The roll clamping assembly 3 can be installed on the waterproof cloth laying mounting frame 1 through the second mounting plate 1c, so that the waterproof cloth roll 5 installed on the roll clamping assembly 3 moves synchronously with the first mounting plate 1a. The roll clamping assembly 3 realizes the installation function of two waterproof cloth rolls 5 through the shaft connection seat 3a and the rotating bracket 3b. The end clamping mechanism 3c clamps the ends of the waterproof cloth roll 5, so that the waterproof cloth roll 5 moves synchronously with the rotating bracket 3b. When the end clamping mechanism 3c clamps the waterproof cloth roll 5, the end of the waterproof cloth roll 5 is axially connected to the output end of the end clamping mechanism 3c, ensuring that the waterproof cloth roll 5 can rotate around its own axis.

[0119] The roll clamping assembly 3 further includes a second rotary driver 3d and a synchronous transmission mechanism 3e;

[0120] The second rotary driver 3d is fixedly installed on one side of the first mounting plate 1a close to the waterproof cloth roll 5;

[0121] The second rotary driver 3d and the shaft connection seat 3a are connected by a synchronous transmission mechanism 3e.

[0122] By controlling the operation of the synchronous transmission mechanism 3e through the output of the second rotary driver 3d, the synchronous transmission mechanism 3e drives the shaft connection seat 3a connected to it to rotate, and the shaft connection seat 3a drives the rotating bracket 3b to rotate, realizing the swapping of the positions of the two waterproof cloth rolls 5, realizing the rotary driving function of the roll clamping assembly 3 for the waterproof cloth roll 5, so that both ends of the rotating bracket 3b can cooperate with the tunnel jumbo, realizing the automatic feeding process of the waterproof cloth roll 5 and improving the feeding efficiency of the waterproof cloth.

[0123] The tensioning and fitting assembly 4 includes a linear driver 4a, a push rod 4b, a tensioning pressing plate 4c and a limiting plate 4d;

[0124] The linear driver 4a is horizontally and fixedly installed on the waterproof cloth laying mounting frame 1, and the output direction of the linear driver 4a is perpendicular to the length direction of the waterproof cloth laying mounting frame 1;

[0125] The tensioning pressing plate 4c is arranged on one side of the waterproof cloth laying mounting frame 1 close to the waterproof cloth roll 5, and 4c can press the waterproof cloth against the primary lining surface;

[0126] The push rod 4b is horizontally arranged between the linear drive 4a and the tensioning plate 4c, one end of the push rod 4b is fixedly connected to the output end of the linear drive 4a, and the other end of the push rod 4b is fixedly connected to the side wall of the tensioning plate 4c close to the waterproof cloth laying mounting frame 1;

[0127] The limit plate 4d is arranged between the linear drive 4a and the tensioning plate 4c. The length direction of the limit plate 4d is consistent with the push rod 4b. One end of the limit plate 4d is fixedly connected to the side wall of the tensioning plate 4c close to the waterproof cloth laying installation frame 1, and the other end of the limit plate 4d is slidably connected to the side wall of the waterproof cloth laying installation frame 1.

[0128] The waterproof cloth pulled out from the waterproof cloth roller 5 can be tightly pressed against the inner wall of the tunnel through the tensioning and fitting component 4, so that the surface of the waterproof cloth is tightly fitted with the primary lining surface. The push rod 4b is driven to move through the output of the linear driver 4a, and the push rod 4b drives the tensioning plate 4c fixedly connected thereto to move toward the direction of the waterproof cloth. The surface of the tensioning plate 4c tightly fits the waterproof cloth on the primary lining surface. During the continuous movement of the waterproof cloth laying and mounting frame 1, the tensioning plate 4c gradually completes the tensioning and squeezing function of the waterproof cloth, which is convenient for the subsequent nail shooting operation.

[0129] The tensioning plate 4c has a certain elasticity. When the tensioning plate 4c is in contact with the waterproof cloth, the elastic force provides an extrusion force for the tensioning plate 4c, so that the waterproof cloth is tightly hung inside the tunnel without tearing the waterproof cloth.

[0130] A contact plate 4c1 is also provided on the side of the tensioning plate 4c close to the initial lining of the tunnel. A telescopic rod 4c2 is horizontally provided between the tensioning plate 4c and the contact plate 4c1. The two ends of the telescopic rod 4c2 are respectively fixedly connected to the contact plate 4c1 and the side walls of the tensioning plate 4c. A spring 4c3 is also sleeved on the telescopic rod 4c2 to provide a certain elastic force for the contact plate 4c1.

[0131] When the tensioning and fitting component 4 is tensioning and fitting the waterproof cloth, the contact plate 4c1 fits against the surface of the waterproof cloth, and the elastic connection between the contact plate 4c1 and the tensioning pressure plate 4c is achieved through the telescopic rod 4c2 and the spring 4c3. When the linear drive 4a is outputting, the tensioning pressure plate 4c is squeezed by the push rod 4b, and the tensioning pressure plate 4c drives the contact plate 4c1 to move. The compression of the telescopic rod 4c2 and the spring 4c3 provides a resisting elastic force for the contact plate 4c1, so that the contact plate 4c1 can always maintain the squeezing effect with the waterproof cloth during operation, that is, during the displacement of the tensioning and fitting component 4, the tensioning and fitting function of the waterproof cloth is always achieved.

[0132] like Figure 12 The implementation method of a waterproof cloth laying device for tunnel construction shown includes the following steps:

[0133] S1: The roller clamping assembly 3 realizes the installation function of the two waterproof cloth rollers 5 through the shaft seat 3a and the rotating bracket 3b, and clamps the ends of the waterproof cloth rollers 5 through the end clamping mechanism 3c, so that the waterproof cloth rollers 5 move synchronously with the rotating bracket 3b;

[0134] S2: The two transmission seats 1b are connected to the compound track transmission system, so that the first mounting plate 1a and the load mounted thereon can follow the output end of the compound track transmission system to reciprocate in an arc shape, thereby realizing the displacement operation of laying the waterproof cloth;

[0135] S3: The push rod 4b is driven to move by the output of the linear drive 4a, and the push rod 4b drives the tensioning plate 4c fixedly connected thereto to move toward the direction of the waterproof cloth. The surface of the tensioning plate 4c makes the waterproof cloth closely fit on the primary lining surface. During the continuous movement of the waterproof cloth laying installation frame 1, the tensioning plate 4c gradually completes the tensioning and squeezing function of the waterproof cloth;

[0136] S4: When hanging, the horizontal pushing mechanism 2f outputs to push the angle deflection driving mechanism 2c and the horizontal mounting frame 2d outward, so that the pneumatic nail gun 2a installed on the horizontal mounting frame 2d reaches the working position, and the angle deflection driving mechanism 2c outputs to change the angle of the pneumatic nail gun 2a relative to the tarpaulin laying mounting frame 1 according to the fixed position change in the tunnel, so that the nails can be driven into the tarpaulin at the best angle;

[0137] S5: The first rotary driver 2e1 outputs to drive the bidirectional threaded rod 2e2 to rotate. When the bidirectional threaded rod 2e2 rotates, it drives the two threaded seats 2e3 threadedly connected thereto to move toward or in the opposite direction, thereby driving the two pneumatic nail guns 2a fixedly mounted on the threaded seats 2e3 to move synchronously. The pneumatic nail guns 2a output to drive nails into the primary lining surface;

[0138] S6: When the hanging direction of the waterproof cloth is opposite, the relative position of the adjustable nail assembly 2 on the waterproof cloth laying mounting frame 1 is adjusted through the output of the vertical displacement drive mechanism 2b, so that the pneumatic nail gun 2a can be located at the joint between the waterproof cloth and the primary lining surface.

[0139] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
