[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The embodiment of the present application discloses a construction device for connecting steel bar sleeves. Figure 1 The construction device includes a bracket 100, a sleeve clamping mechanism 200 for tightening the sleeve, a sleeve feeding mechanism 300 for adding the sleeve to the sleeve clamping mechanism 200, and a steel bar tightening mechanism 400.

[0039] Reference Figure 2 The sleeve clamping mechanism 200 includes a base 210 and two clamping jaws 220. The base 210 is mounted on the bracket 100 and defines a receiving slot 211 for accommodating the sleeve. The bottom of the receiving slot 211 is configured in an arc shape. Along the sleeve axis, the two clamping jaws 220 are disposed on either side of the base 210 and are rotatably connected to the base 210. A rotating assembly 500 is provided on the base 210 to drive the clamping jaws 220 to rotate.

[0040] The rotation assembly 500 includes a rotation rod 510 and a drive cylinder 520. The drive cylinder 520 is positioned in a direction toward or away from the ground. The cylinder body of the drive cylinder 520 is fixedly connected to the bracket 100, and the piston rod of the drive cylinder 520 is fixedly connected to the base 210, thereby enabling the drive cylinder 520 to drive the base 210 to move toward or away from the ground. The rotation rods 510 correspond one-to-one with the clamping jaws 220, with one end of the rotation rod 510 being rotationally connected to the corresponding clamping jaw 220 and the other end being rotationally connected to the bracket 100.

[0041] To adapt the clamping jaws 220 to clamp sleeves of varying diameters, the rotating rod 510 includes a rotating cylinder 511 and a rotating sub-rod 512. The rotating sub-rod 512 is sealingly and slidably connected to the rotating cylinder 511 in directions toward or away from the bottom of the rotating cylinder 511. The end of the rotating sub-rod 512, which is away from the ground, is rotatably connected to the clamping jaws 220, while the end of the rotating cylinder 511, which is closer to the ground, is rotatably connected to the base 210. The rotating cylinder 511 is connected to an oil tank 513 via a connecting pipe 516, which is equipped with a pressure valve 514.

[0042] In order to make the clamping force of the two jaws 220 on the sleeve the same so that the sleeve is not easily displaced, the connecting pipe 516 includes two connecting sub-pipes 5161 and a connecting sub-pipe 5162. The connecting sub-pipes 5161 correspond one-to-one to the rotating cylinders 511, and one end of the connecting sub-pipe 5161 is connected to the corresponding rotating cylinder 511, and the other end is connected to the connecting sub-pipe 5162.

[0043] The sleeve loading mechanism 300 includes a hopper 310 and a discharge pipe 320. The hopper 310 is fixedly connected to the bracket 100 and is mounted above the sleeve clamping mechanism 200. One end of the discharge pipe 320 is connected to the hopper 310, and the other end extends obliquely to above the accommodating groove 211. The opening at one end of the discharge pipe 320 away from the hopper 310 can only accommodate one sleeve.

An opening and closing hole for inserting the opening and closing plate 332 is provided on the side of the discharge pipe 320 away from the ground. The cylinder body of the opening and closing cylinder 331 is fixedly connected to the bracket 100. The piston rod of the opening and closing cylinder 331 is fixedly connected to the opening and closing plate 332. A plug-in hole 321 for inserting the opening and closing plate 332 is provided on the side of the discharge pipe 320 away from the ground.

[0045] The driving cylinder 520 is started to move the base 210 away from the ground under the action of the driving cylinder 520, so that the rotating rod 510 drives the corresponding clamping jaws 220 to rotate, and the two clamping jaws 220 are opened. The opening and closing cylinder 331 is started to make the piston rod of the opening and closing cylinder 331 drive the opening and closing plate 332 to be pulled out from the plug hole 321, so that the opening and closing plate 332 opens the pipe mouth of the discharge pipe 320, and the sleeve rolls out of the discharge pipe 320 and falls onto the base 210. When a sleeve rolls out of the discharge pipe 320, Start the opening and closing cylinder 331 so that the piston rod of the opening and closing cylinder 331 drives the opening and closing plate 332 to be inserted into the plug hole 321, so that the opening and closing plate 332 closes the pipe mouth of the discharge pipe 320, so that the sleeve is not easily discharged excessively and affects the normal operation of the sleeve clamping mechanism 200; start the driving cylinder 520 so that the base 210 moves toward the ground under the action of the driving cylinder 520, so that the rotating rod 510 drives the corresponding clamping jaws 220 to rotate, thereby realizing the closure of the two clamping jaws 220, that is, the clamping of the sleeve.

[0046] The side of the clamping jaw 220 that contacts the sleeve is set as an arc surface. On the one hand, the clamping jaw 220 limits the sleeve to prevent the sleeve from moving. On the other hand, the clamping jaw 220 guides the fallen sleeve, thereby preventing the sleeve from falling to the ground.

[0047] During the storage and processing of the sleeve, some metal debris will remain in the sleeve, which may affect the connection between the sleeve and the steel bar. Based on this, a cleaning assembly 900 is provided on the bracket 100. The cleaning assembly 900 includes a cleaning motor 910, a cleaning brush 920, and a cleaning cylinder 930. The cylinder body of the cleaning cylinder 930 is fixedly connected to the discharge pipe 320, and the body of the cleaning motor 910 is fixedly connected to the piston rod of the cleaning cylinder 930, so that the cleaning cylinder 930 drives the cleaning motor 910 to move along the sleeve axis toward or away from the discharge pipe 320. The cleaning brush 920 is coaxially fixedly connected to the output shaft of the cleaning motor 910. The discharge pipe 320 is provided with an insertion hole for the cleaning brush 920.

[0048] The staff starts the cleaning motor 910 to make the cleaning motor 910 run, and then starts the cleaning cylinder 930, so that the cleaning cylinder 930 drives the cleaning motor 910 to move toward the discharge pipe 320, and at the same time, the cleaning brush 920 is inserted into the sleeve through the insertion hole to clean the debris in the sleeve; after cleaning is completed, control the cleaning cylinder 930 to pull the cleaning brush 920 out of the sleeve.

[0052] Reference Figure 3 and Figure 4 A semi-annular groove 4121 is correspondingly opened on the rotating portion 412 and the positioning portion 411. When the rotating portion 412 and the positioning portion 411 rotate until the free end of the rotating portion 412 contacts the positioning portion 411, the notches of the two semi-annular grooves 4121 are aligned and connected to form an annular groove.
