Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar connection, and in particular relates to a steel bar mechanical connection device. Background Art

[0002] In the field of construction, mechanical connection of steel bars is a common method of connecting steel bars. It is to connect steel bars and connecting parts together, so that the force generated in one steel bar is transmitted to another steel bar to increase the connection strength of the steel bars. The quality of the joints in this connection method is stable and reliable, is not affected by the chemical composition of the steel bars, is less affected by human factors, and is easy to operate. In the existing technology, it is usually necessary to manually hold a sleeve in one hand and a steel bar in the other hand, and screw one end of the steel bar thread into the sleeve to complete the connection. When the number of steel bars that need to be mechanically connected is large, this manual twisting connection method not only takes up a lot of manpower, but is also inefficient. Therefore, we propose a steel bar mechanical connection device to solve the above problems. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a mechanical steel bar connection device, which solves the problems of large manpower occupation and low efficiency when the number of steel bars is large.

[0004] The utility model is realized by the following scheme: a steel bar mechanical connection device, comprising:

[0005] Mobile racks;

[0006] A driving motor is fixed inside the mobile frame;

[0007] A transmission rod connected to the output shaft of the drive motor;

[0008] A clamp is fixed to the end of the transmission rod away from the output shaft of the drive motor, and is used to clamp the fixed sleeve / rebar. The drive motor drives the transmission rod to drive the clamp to rotate, so as to achieve screw connection between the clamped sleeve and the rebar, or screw connection between the clamped rebar and the sleeve; and

[0009] The limiting component is used to control the driving motor to stop working so as to limit the screwing depth between the steel bar and the sleeve.

[0010] A further improvement of the steel bar mechanical connection device of the present invention is that the limiting component includes a ruler arranged on the side of the movable frame facing the clamp, a marking plate mounted on the outside of the ruler and movable along the length direction of the ruler, and a transmission member for converting the rotational motion into movement of the marking plate along the ruler, and the transmission member is connected to the drive motor to achieve synchronous rotation with the transmission rod.

[0011] A further improvement of the steel bar mechanical connection device of the present invention is that the limiting component also includes a baffle fixed to the side of the movable frame facing the clamp, and the ruler is fixed on the baffle, and the distance between the baffle and the initial position of the marking plate is the limited maximum screwing depth.

[0012] A further improvement of the steel bar mechanical connection device of the present invention is that the transmission part includes a first gear, a second gear, a screw rotatably connected to the baffle, and a nut assembly threadedly connected to the screw and connected to the marking plate. One end of the screw connected to the baffle passes through the baffle and extends into the movable frame. The first gear is fixed to the output shaft of the drive motor, and the second gear is fixed to one end of the screw located in the movable frame and meshes with the first gear.

[0013] A further improvement of the steel bar mechanical connection device of the present invention is that the nut assembly includes two half nuts, one end of the two half nuts on opposite sides are hinged to each other for relative opening and closing of the two half nuts, and the other end of the two half nuts on opposite sides are locked to each other for locking the two half nuts in a closed state.

[0014] A further improvement of the mechanical steel bar connection device of the present invention is that a universal joint is fixedly connected between the transmission rod and the output shaft of the driving motor.

[0015] A further improvement of the mechanical steel bar connection device of the present invention is that a moving wheel is provided at the bottom of the moving frame, and a handrail is fixedly connected to the outside of the moving frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The utility model uses a driving motor with an automatic start-stop function to replace the manual torque mechanical connection, which is easy to operate and has a fast screwing speed, can greatly improve work efficiency and reduce labor input.

[0018] 2. The utility model can first move the marking plate to the position of the scale on the ruler so that it is consistent with the required size of the steel bar screwed into the sleeve. When the driving motor drives the transmission rod to rotate the steel bar / sleeve fixed by the clamp, it can also drive the screw to rotate. The nut threadedly connected to the screw will move along the screw, thereby moving the marking plate along the ruler and abutting against the baffle. At this time, the driving motor stops working, and the steel bar is screwed into the sleeve to the required size to achieve precise connection. It can be adjusted according to different size requirements, greatly improving the practicality of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to solve the problem of high manpower consumption and low efficiency when a large number of steel bars are connected, the present invention provides a steel bar mechanical connection device. The following is a further description of the steel bar mechanical connection device with reference to a specific embodiment and the accompanying drawings.

[0025] See Figures 1 to 4 As shown, a steel bar mechanical connection device includes:

[0026] Mobile rack 1;

[0027] The driving motor 2 is fixed inside the mobile frame 1;

[0028] The transmission rod 3 is connected to the output shaft of the driving motor 2;

[0029] The clamp 4 is fixed to the end of the transmission rod 3 away from the output shaft of the drive motor 2, and is used to clamp the fixed sleeve / rebar. The drive motor 2 drives the transmission rod 3 to drive the clamp 4 to rotate, so as to achieve screw connection between the clamped sleeve and the rebar, or screw connection between the clamped rebar and the sleeve; and

[0030] The limiting component is used to control the driving motor 2 to stop working so as to limit the screwing depth between the steel bar and the sleeve.

[0031] Specifically, the drive motor 2 is a self-starting and stopping motor; by using a drive motor 2 with a self-starting and stopping function to replace the manual torque mechanical connection, the operation is simple and the screwing speed is fast, which can greatly improve the work efficiency and reduce the labor input. Moreover, the size of the threaded end of the steel bar screwed into the sleeve can be controlled to the required size, thereby achieving precise docking.

[0032] Among them, see Figure 2-3As shown, the limiting assembly includes a scale 6 provided on the side of the mobile frame 1 facing the clamp 4, a marking plate 7 sleeved on the outside of the scale 6 and movable along the length direction of the scale 6, and a transmission member 5 for converting the rotational motion into movement of the marking plate 7 along the scale 6. The transmission member 5 is in transmission connection with the drive motor 2 to achieve synchronous rotation with the transmission rod 3.

[0033] Furthermore, the drive motor 2 is started to drive the transmission rod 3 and the transmission member 5 to rotate synchronously, thereby screwing the clamped sleeve to the steel bar, or screwing the clamped steel bar to the sleeve. During the process, the transmission member 5 will drive the marking plate 7 to move along the scale 6. The scale 6 is provided with a scale value. The screwing depth between the steel bar and the sleeve can be determined according to the moving position of the marking plate 7, thereby controlling the drive motor 2 to stop working to achieve precise docking.

[0034] The limiting assembly further includes a baffle 9 fixed to the side of the mobile frame 1 facing the fixture, and the scale 6 is fixed on the baffle 9. The distance between the baffle 9 and the initial position of the marking plate 7 is the maximum screwing depth of the limit;

[0035] The transmission member 5 includes a first gear 503, a second gear 504, a screw 501 rotatably connected to the baffle 9, and a nut assembly 502 threadedly connected to the screw 501 and connected to the marking plate 7. The end of the screw 501 connected to the baffle 9 passes through the baffle 9 and extends into the movable frame 1. The first gear 503 is fixed on the output shaft of the drive motor 2, and the second gear 504 is fixed to one end of the screw 501 located in the movable frame 1 and meshes with the first gear 503.

[0036] For details, see Figure 1-2 As shown, there are two scales 6, and the two scales 6 are respectively fixed to the two ends of the baffle 9, and the two ends of the marking plate 7 are respectively sleeved on the scales 6;

[0037] Furthermore, before starting the drive motor 2, the threaded end of the steel bar is screwed into the sleeve a little (which can reduce the later docking time), and then the drive motor 2 drives the transmission rod 3 to rotate, thereby causing the steel bar / sleeve clamped and fixed by the clamp 4 to rotate, thereby screwing it with the handheld sleeve / steel. At the same time, when the output shaft of the drive motor 2 rotates, it will drive the screw 501 to rotate through the engagement of the first gear 503 and the second gear 504, thereby driving the nut assembly 502 to move along the screw 501, and then drive the marking plate 7 to move along the scale 6 and against the baffle 9. At this time, the drive motor 2 stops working, indicating that the threaded end of the steel bar has been screwed into the sleeve to the required size, thereby achieving precise connection.

[0038] Among them, see Figure 2As shown, the nut assembly 502 includes two half nuts 5021, one end of the two half nuts 5021 on the opposite side is hinged to each other for relative opening and closing of the two half nuts 5021, and the other end of the two half nuts 5021 on the opposite side is locked to each other for locking the two half nuts 5021 in a closed state.

[0039] For details, see Figure 4 As shown, the two half nuts 5021 are divided into upper and lower half nuts. The bottom of the lower half nut is fixedly connected to a lifting plate 5022. The top of the marking plate 7 is provided with a lifting groove 5025 for the lifting plate 5022 to be raised and lowered. The lifting groove 5025 has two limiting grooves 5024 formed on the two opposite inner walls. Two limiting blocks 5023 are fixedly installed on the opposite sides of the lifting plate 5022, which slide along the two limiting grooves 5024 respectively.

[0040] Furthermore, by opening the two half nuts 5021 and moving the lifting plate 5022 downward along the lifting slot 5025, the lower half nut is controlled to move downward, so that the lower half nut is not in contact with the screw 501, and the marking plate 7 can be pushed to move along the scale on the ruler 6, which is convenient for adjustment according to the required size; then the lifting plate 5022 is pulled upward, and the upper half nut and the lower half nut are snap-closed and screwed together with the screw 501; the cooperation of the limit slot 5024 and the limit block 5023 can prevent the lifting plate 5022 from separating from the lifting slot 5025.

[0041] Among them, see Figure 3 As shown, a universal joint 8 is fixedly connected between the transmission rod 3 and the output shaft of the drive motor 2 .

[0042] By arranging the universal joint 8 to match the angle change of the transmission, the effect is better.

[0043] Among them, see Figure 1 As shown, the bottom of the mobile frame 1 is provided with a moving wheel 102 , and the outside of the mobile frame 1 is fixedly connected with an armrest 103 .

[0044] The armrest 103 is used to push the movable frame 1 to move on the movable wheels 102, so that the device can be moved to the working place conveniently.

[0045] Among them, see Figure 2 As shown, an operating station 101 is fixedly connected to the top of the mobile frame 1, and a switch 104 is provided on the operating station 101.

[0046] The drive motor 2 can be manually controlled to start / stop via the switch 104, which is convenient for the operator to operate.
