Description

Technical Field

[0001] This utility model relates to the field of engineering construction, specifically a robotic arm device for connecting steel bars. Background Technology

[0002] There are three main types of rebar connections: 1. Lap splice: applicable to rebars with a diameter ≤25mm, and up to 28mm for compression rebars, but not applicable to axially tensioned and slightly eccentrically tensioned members;

[0003] 2. Welded connection: Applicable to vertical reinforcing bars. The difference between reinforcing bars of different diameters shall not exceed 7mm, and welding quality inspection is required.

[0004] 3. Mechanical connections: such as straight threaded sleeves, suitable for reinforcing bars with a diameter ≥18mm, especially suitable for critical load-bearing components such as foundation beams and frame columns.

[0005] When connecting steel bars in a tunnel, a waterproof membrane is installed inside the tunnel. To prevent damage to the waterproof membrane during welding, a mechanical connection is required. The mechanical connection currently used usually uses a hydraulic cylinder to press the steel bars and steel bar connecting sleeves to complete the connection. However, due to the weight of the equipment and its dispersed location, it is difficult to transport and it is also difficult for a single person to use the equipment, resulting in a lot of time being spent and reducing work efficiency.

[0006] Therefore, a robotic arm device for connecting steel bars is proposed to address the above problems. Utility Model Content

[0007] To overcome the shortcomings of existing technologies and solve the problems of cumbersome transportation and inconvenient single-person operation due to the weight and dispersed placement of the device, which leads to excessive time consumption and reduced work efficiency, this utility model proposes a robotic arm device for rebar connection.

[0008] The technical solution adopted by this utility model to solve its technical problem is as follows: The mechanical arm device for connecting steel bars according to this utility model includes a movable box, a box door rotatably connected inside the movable box, a support block fixedly connected to the bottom of the movable box, two lifting components arranged on the outside of the movable box, each lifting component including a rotating rod fixedly connected inside the movable box, a transmission plate rotatably connected to the outside of the rotating rod, a handle fixedly connected inside the transmission plate, a pressing groove opened inside the transmission plate, a connecting plate fixedly connected to the outside of the transmission plate, a base plate fixedly connected to the end of the connecting plate, and casters fixedly connected to the bottom of the base plate.

[0009] Preferably, the outer side of the mobile box is provided with two pressing components. The pressing components include two upright plates fixedly connected to the outer side of the mobile box, and a support rod is fixedly connected to the outer side of the upright plate. A limit plate is fixedly connected to the end of the support rod.

[0010] Preferably, the pressing assembly further includes a pressing plate rotatably connected to the outside of the support rod, a pressing rod fixedly connected between the two pressing plates, and the outside of the pressing rod slidably connected to the inside of the pressing groove.

[0011] Preferably, the mobile box is provided with two positioning components. The positioning components include two first slide rods slidably connected inside the mobile box, a positioning rod rotatably connected between the two first slide rods, the first slide rods passing through the mobile box, and an mounting plate fixedly connected to the top of the first slide rods.

[0012] Preferably, the positioning component further includes a second slide rod fixedly connected to the top of the mounting plate, the second slide rod passing through the movable box and slidably connected, a limit plate fixedly connected to the top of the second slide rod, the outer side of the limit plate being slidably connected to the inside of the movable box, and a spring fixedly connected between the mounting plate and the movable box.

[0013] Preferably, the top of the mobile box is provided with a working component, the working component including a hydraulic cylinder fixedly connected to the top of the mobile box, a pressing block fixedly connected to the end of the hydraulic cylinder, two auxiliary plates fixedly connected to the top of the mobile box, the two auxiliary plates being slidably connected to the pressing block, and a support plate fixedly connected to the top of the mobile box.

[0014] Preferably, the outer side of the transmission plate is slidably connected to the inside of the movable box, the outer side of the handle is slidably connected to the inside of the movable box, and the outer side of the transmission plate is slidably connected to the outer side of the positioning rod.

[0015] The advantages of this utility model are:

[0016] 1. This utility model allows the transmission plate and connecting plate to rotate along the rotating rod by pulling the handle, thereby moving the connecting plate and the casters. Pressing the handle then causes the connecting plate to lift the casters and lift the movable box. The connecting plate then abuts against the inside of the movable box, restricting the position of the casters and separating the support block from the ground. This allows the movable box to move smoothly, and the necessary tools can be placed inside the movable box, reducing the time required for scattered handling. Furthermore, the lever principle reduces the impact of weight on the lifting of the movable box's end, ensuring smooth subsequent movement and reducing handling hassles, thus improving the device's handling efficiency.

[0017] 2. This utility model pushes the pressing plate, causing it to rotate along the support rod, which in turn drives the pressing rod into the pressing groove. This fixes the position of the transmission plate, thereby fixing the position of the caster wheel and ensuring its stability. This reduces the possibility of the device being affected by uneven road surfaces. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-4 As shown, a robotic arm device for connecting steel bars includes a movable box 1, a door 2 rotatably connected inside the movable box 1, a support block 3 fixedly connected to the bottom of the movable box 1, and two lifting components on the outside of the movable box 1. The lifting components include a rotating rod 8 fixedly connected inside the movable box 1, a transmission plate 9 rotatably connected to the outside of the rotating rod 8, a handle 10 fixedly connected inside the transmission plate 9, a pressing groove 11 opened inside the transmission plate 9, a connecting plate 12 fixedly connected to the outside of the transmission plate 9, a base plate 13 fixedly connected to the end of the connecting plate 12, and casters 14 fixedly connected to the bottom of the base plate 13.

[0028] During operation, pulling the handle 10 causes the transmission plate 9 and connecting plate 12 to rotate along the rotating rod 8, thereby moving the connecting plate 12 and the caster wheel 14. Then, pressing the handle 10 causes the connecting plate 12 to lift the caster wheel 14, which then abuts against the inside of the moving box 1, thus restricting the position of the caster wheel 14. This separates the support block 3 from the ground, allowing the moving box 1 to move smoothly. The moving box 1 can hold the necessary tools, reducing the time required for scattered handling. Furthermore, the lever principle reduces the impact of weight on the lifting of the end of the moving box 1, ensuring smooth subsequent movement of the moving box 1 and reducing handling hassles, thereby improving the handling efficiency of the device.

[0029] The mobile box 1 has two pressing components on its outer side. The pressing components include two upright plates 15 fixedly connected to the outer side of the mobile box 1. A support rod 16 is fixedly connected to the outer side of the upright plate 15. A limit plate 17 is fixedly connected to the end of the support rod 16.

[0030] The pressing assembly also includes a pressing plate 18 rotatably connected to the outside of the support rod 16, and a pressing rod 19 is fixedly connected between the two pressing plates 18. The outside of the pressing rod 19 is slidably connected to the inside of the pressing groove 11.

[0031] During operation, by pushing the pressing plate 18, the pressing plate 18 rotates along the support rod 16, thereby driving the pressing rod 19 into the pressing groove 11, which can fix the position of the transmission plate 9, thereby fixing the position of the caster wheel 14, thus ensuring the stability of the caster wheel 14, and reducing the possibility of the device being affected when encountering uneven road surfaces.

[0032] The mobile box 1 is equipped with a working component on its top. The working component includes a hydraulic cylinder 4 fixedly connected to the top of the mobile box 1, a pressing block 5 fixedly connected to the end of the hydraulic cylinder 4, two auxiliary plates 6 fixedly connected to the top of the mobile box 1, the two auxiliary plates 6 being slidably connected to the pressing block 5, and a support plate 7 fixedly connected to the top of the mobile box 1.

[0033] During operation, the reinforcing bars and the reinforcing bar connecting sleeve are placed between the auxiliary plate 6 and the support plate 7. Then, the hydraulic cylinder 4 drives the pressing block 5 to move, thereby connecting the reinforcing bars and the reinforcing bar connecting sleeve together, which facilitates the subsequent use of the reinforcing bars.

[0034] The transmission plate 9 is slidably connected to the inside of the movable box 1 on the outside, the handle 10 is slidably connected to the inside of the movable box 1 on the outside, and the transmission plate 9 is slidably connected to the outside of the positioning rod 20 on the outside.

[0035] During operation, the transmission plate 9 can be stored in the movable box 1, while the positioning rod 20 can restrict the position of the transmission plate 9.

[0036] Example 2

[0037] Please see Figure 5 As shown in the first embodiment, as another implementation of the present invention, the mobile box 1 is provided with two positioning components. The positioning components include two first slide rods 21 that are slidably connected inside the mobile box 1. A positioning rod 20 is rotatably connected between the two first slide rods 21. The first slide rods 21 pass through the mobile box 1, and an mounting plate 22 is fixedly connected to the top of the first slide rods 21.

[0038] The positioning component also includes a second slide rod 23 fixedly connected to the top of the mounting plate 22. The second slide rod 23 passes through the movable box 1 and is slidably connected. A limit plate 25 is fixedly connected to the top of the second slide rod 23. The outer side of the limit plate 25 is slidably connected to the inside of the movable box 1. A spring 24 is fixedly connected between the mounting plate 22 and the movable box 1.

[0039] During operation, pulling the mounting plate 22 moves the first slide bar 21 and the second slide bar 23, compressing the spring 24 and raising the positioning rod 20. Then, the handle 10 is placed inside the moving box 1, and the mounting plate 22 is released. The spring 24 then moves the positioning rod 20 to the outside of the transmission plate 9, thus fixing the position of the transmission plate 9. This prevents the caster wheel 14 and the base plate 13 from being in constant contact with the ground due to the lack of a limit, thereby reducing wear on the base plate 13 and the caster wheel 14 and improving their service life.

[0040] The working principle is as follows: by pulling the handle 10, the transmission plate 9 and the connecting plate 12 are driven to rotate along the rotating rod 8, thereby moving the connecting plate 12 and the caster wheel 14. Then, pressing the handle 10 causes the connecting plate 12 to drive the caster wheel 14 to lift the moving box 1. Subsequently, the connecting plate 12 will abut against the inside of the moving box 1, thereby restricting the position of the caster wheel 14, thus separating the support block 3 from the ground, so that the moving box 1 can move smoothly. The moving box 1 can hold the necessary tools, thereby reducing the time required for scattered transportation. Furthermore, through the lever principle, the impact of weight on the lifting of the end of the moving box 1 can be reduced, thereby ensuring that the moving box 1 can move smoothly in the future, reducing the trouble of transportation, and thus improving the transportation efficiency of the device.
