Description

Technical Field

[0001] The utility model relates to a steel bar installation stand, in particular to a multifunctional highway tunnel steel bar installation and waterproof board laying stand. Background Art

[0002] The correct installation of tunnel reinforcement is the key to ensuring the structural safety of tunnel buildings. First of all, the reinforcement must meet the design specifications, the quantity and size should be consistent with the design, and the installation position and spacing should comply with the specifications and regulations. Then, during the installation process, the reinforcement should be tied and fixed in strict accordance with the specifications and requirements, and no looseness or misalignment should occur. Finally, after the tunnel reinforcement is installed, it is necessary to measure and inspect it in place to ensure that the installation quality meets the requirements.

[0003] When the specifications, quantity and size of the steel bars are consistent with the design, the location and spacing of the steel bars will determine the quality of the tunnel. If the installation location is inaccurate or the spacing is too large, the strength of the subsequent concrete pouring will be insufficient, thus affecting the installation of the tunnel structure; if the spacing is too small, over-reinforcement damage may occur, which will increase the construction cost. Common auxiliary equipment for steel bar installation includes steel bar installation stands or manual scaffolding installation.

[0004] The common steel bar installation platform has a conveying function, which can transport the steel bars on the ground to the installation platform, and then the construction workers move them to the installation location for installation. Since the weight of the steel bars is very large, manual transportation alone will greatly increase the construction cost and affect the construction efficiency. Utility Model Content

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0037] See also Figure 1 to Figure 6 As an embodiment of the utility model, the multifunctional highway tunnel steel bar installation and waterproof board laying stand comprises a support frame 1, and a connecting frame 9 arranged on the support frame 1, and a support rod 10 is fixedly installed on the connecting frame 9;

[0038] The support frame 1 is provided with a flipping mechanism, and the flipping mechanism is connected to a material storage platform 4, and the flipping mechanism can drive the material storage platform 4 to flip so that the material storage platform 4 is parallel or perpendicular to the support frame 1;

[0039] The support frame 1 is provided with a lifting mechanism, which can drive the connecting frame 9 to rise or fall when the flipping mechanism is in action, so that the support rod 10 is away from or close to the support frame 1;

[0040] The support frame 1 is also provided with an intermittent translation mechanism. When the material storage platform 4 is perpendicular to the support frame 1 , the intermittent translation mechanism can drive the material storage platform 4 to translate intermittently along the length direction of the support frame 1 .

[0041] In this embodiment, the material storage platform 4 is arched, and its size is set according to the size of the tunnel to be constructed. In the initial state, the material storage platform 4 is parallel to the support frame 1 and fits with the support frame 1. The processed steel bars are placed on the material storage platform 4, and the material storage platform 4 is driven to flip through the flipping mechanism so that the material storage platform 4 is perpendicular to the support frame 1, so that the steel bars in the material storage platform 4 are parallel to the cross section of the tunnel, so as to facilitate the construction personnel to tie and install. When the flipping mechanism is activated, the lifting mechanism will drive the connecting frame 9 to descend to prevent the flipped material storage platform 4 from colliding with the support rod 10 and thus damaging the platform, and to enable the subsequent intermittent translation mechanism to move smoothly.

[0042] When the material storage platform 4 is perpendicular to the support frame 1 , the intermittent translation mechanism will drive the material storage platform 4 to be intermittently translated along the length direction of the support frame 1 to facilitate construction workers to take out the steel bars from the material storage platform 4 and place them on the support rod 10 .

[0043] After all the steel bars are taken out from the storage platform 4, the intermittent translation mechanism will drive the storage platform 4 to do reverse intermittent translation until the storage platform 4 reaches the initial vertical position. At this time, the construction personnel begin to use the stand to complete the laying of the waterproof board.

[0044] After the waterproof board is laid, the flip mechanism will drive the material storage platform 4 to flip so that the material storage platform 4 is parallel to the support frame 1, so that the construction personnel can easily fill the steel bars into the material storage platform 4. While the flip mechanism is in motion, the lifting mechanism will drive the connecting frame 9 to rise, so that the support rod 10 rises, so that the steel bars placed on the support rod 10 rise to the binding installation position, so that the construction personnel can easily carry out the installation process.

[0045] As a further solution of the utility model, the intermittent translation mechanism includes a guide rail 2 fixedly mounted on the support frame 1; a slider 3 rotatably engaged with the storage platform 4 is slidably engaged on the guide rail 2; a motor 11 is fixedly mounted on the slider 3; a half gear 12 rotatably connected to the slider 3 is fixedly connected to the output end of the motor 11; a rack plate 201 meshing with the half gear 12 is fixedly mounted on the guide rail 2.

[0046] In this embodiment, when the motor 11 is started, it will drive the half gear 12 to rotate. When the half gear 12 is engaged with the rack plate 201, the slider 3 will be displaced, thereby driving the storage platform 4 to move; the displacement distance is the length of the engagement between the rack plate 201 and the half gear 12; the steel bars are driven to move by driving the storage platform 4 to move.

[0047] When the half gear 12 is not meshed with the rack plate 201 , the slider 3 will maintain its position, thereby keeping the position of the storage platform 4 unchanged; while the storage platform 4 is stationary, the construction workers will take out the steel bars and place them on the support rod 10 .

[0048] The intermittent translation mechanism drives the storage table 4 to move, thereby driving the steel bars to move, and the moving distance of the steel bars is fixed, so the binding and installation distance between the steel bars can be accurately controlled, and the construction quality of the steel bar project can be improved.

[0049] As a further solution of the utility model, the flipping mechanism includes a hydraulic cylinder 5 with one end rotatably mounted on the slider 3, and the other end of the hydraulic cylinder 5 is rotatably mounted on the storage platform 4, and the rotation center of the hydraulic cylinder 5 and the slider 3 is higher than the rotation center of the slider 3 and the storage platform 4.

[0050] In this embodiment, since the rotation center of the hydraulic cylinder 5 and the slider 3 is higher than the rotation center of the slider 3 and the storage table 4, when the hydraulic cylinder 5 is extended, it will push the storage table 4 to rotate along the rotation connection between it and the slider 3, thereby realizing flipping, so that the vertical storage table 4 is flipped to be parallel to the support frame 1; otherwise, the parallel storage table 4 is flipped to be perpendicular to the support frame 1.

[0051] As a further solution of the utility model, the lifting mechanism includes a first bevel gear 401 fixedly mounted on the storage platform 4, and the axis of the first bevel gear 401 is located on the same straight line as the rotation axis of the slider 3 and the storage platform 4; a second bevel gear 301 meshing with the first bevel gear 401 is rotatably mounted on the slider 3; a guide rod 6 slidably engaged with the second bevel gear 301 is rotatably mounted on the guide rail 2; third bevel gears 601 are fixedly mounted at both ends of the guide rod 6; a connecting rod 7 is rotatably mounted on the guide rail 2, and a fourth bevel gear 701 is fixedly mounted on one end of the connecting rod 7 close to the guide rail 2.

[0052] In this embodiment, when the turning mechanism drives the material storage platform 4 to turn over, the first bevel gear 401 will rotate accordingly, thereby driving the second bevel gear 301 to rotate. When the second bevel gear 301 rotates, the third bevel gear 601 will be driven to rotate through the guide rod 6, thereby driving the fourth bevel gear 701 to rotate, so that the connecting rod 7 can rotate.

[0053] As a further solution of the utility model, the number of teeth of the first bevel gear 401 is greater than the number of teeth of the second bevel gear 301 ; the number of teeth of the second bevel gear 301 is greater than the number of teeth of the third bevel gear 601 ; the number of teeth of the third bevel gear 601 is greater than the number of teeth of the fourth bevel gear 701 .

[0054] In this embodiment, since the storage table 4 can only flip 90°, the first bevel gear 401 can only rotate a quarter of a circle. Through the two-stage speed increase of the first bevel gear 401 and the second bevel gear 301 and the third bevel gear 601 and the fourth bevel gear 701, the number of circles that the connecting rod 7 can rotate is much greater than that of the first bevel gear 401.

[0055] As a further solution of the utility model, the lifting mechanism further includes a spiral groove 702 provided on the connecting rod 7 , an internal threaded sleeve 8 is threadedly connected to the spiral groove 702 , and the internal threaded sleeve 8 is fixedly connected to the connecting frame 9 .

[0056] In this embodiment, when the connecting rod 7 rotates, the spiral groove 702 will rotate accordingly, and the internal threaded sleeve 8 can rise or fall in the length direction of the connecting rod 7 through threaded cooperation, thereby driving the connecting frame 9 to rise or fall, allowing the support rod 10 to rise or fall.

[0057] Since the lifting mechanism and the flipping mechanism cooperate with each other, when the storage platform 4 flips vertically, the support rod 10 is lowered; when the storage platform 4 flips parallel, the support rod 10 is raised, thereby avoiding collision between the storage platform 4 and the support rod 10, and also facilitating the construction workers to tie and install the steel bars (avoiding manual lifting of the steel bars from the support rod 10 to the installation site).

[0058] As a further solution of the utility model, the support rod 10 is provided with a plurality of grooves 1001 , and the plurality of grooves 1001 are equidistantly distributed, and the spacing between the grooves 1001 is the length of the engagement between the half gear 12 and the rack plate 201 .

[0059] In this embodiment, when the intermittent translation mechanism drives the storage platform 4 to translate intermittently, the intermittent translation mechanism will cooperate with the groove 1001. The position where the storage platform 4 stops after translation is opposite to a groove 1001. The construction personnel will take the steel bars out of the storage platform 4 and place the steel bars in the groove 1001 to avoid the steel bars hindering the movement of the intermittent translation mechanism when it returns; the distance between the steel bars can also be controlled to improve the construction quality of the binding project.

[0060] The storage platform 4 is driven to flip by the flipping mechanism, so that the steel bars can be transported from the ground to the tunnel cross section; the steel bars can be evenly distributed on the support rod 10 through the cooperation between the intermittent translation mechanism and the groove 1001; the steel bars can be accurately delivered to the installation position through the cooperation between the lifting mechanism and the flipping mechanism; it saves trouble and labor, and ensures that the steel bars are in the correct installation position and the spacing is accurate; it ensures the quality of the project and saves construction costs

[0061] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
