Detailed Implementation

[0018] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of this utility model. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of this utility model, but are only for illustrating the essential spirit of the technical solution of this utility model.

[0019] like Figure 1 As shown. This utility model discloses a vertical rebar climbing and extrusion connection device, which includes a rebar climbing mechanism, an extrusion cylinder, a vertical lifting mechanism, and a horizontal telescopic mechanism. One side of the rebar climbing mechanism is used to loop around the vertical rebar 23 and move along the axial direction of the vertical rebar 23. The other side of the rebar climbing mechanism is connected to the vertical lifting mechanism. The top of the vertical lifting mechanism is provided with a horizontal telescopic mechanism, which is used to drive the horizontal telescopic mechanism to move vertically up and down. The extrusion cylinder is set on the horizontal telescopic mechanism and is driven by the horizontal telescopic mechanism to move horizontally.

[0020] When connecting the vertical reinforcing bars 23, a reinforcing bar sleeve 14 is fitted at the connection position. After the reinforcing bar climbing mechanism is looped around the outer periphery of the vertical reinforcing bar 23, the reinforcing bar climbing mechanism is controlled to rise along the axial direction of the vertical reinforcing bar 23 until the pressing cylinder 22 reaches the connection position of the vertical reinforcing bar 23. Then, the pressing cylinder 22 is moved to the position of the reinforcing bar sleeve 14 of the vertical reinforcing bar through the vertical lifting mechanism and the horizontal telescopic mechanism. While controlling the vertical lifting mechanism to move up and down, the pressing cylinder 22 presses the reinforcing bar sleeve 14 to achieve the connection of the vertical reinforcing bar 23.

[0021] Furthermore, the rebar climbing mechanism includes a climbing frame, a driving concave wheel set, a follower concave wheel set, and a climbing motor 4. The climbing frame is used to axially encircle the outer periphery of the vertical rebar 23. The driving concave wheel set and the follower concave wheel set are slidably nested on opposite sides inside the climbing frame. The driving concave wheel set and the follower concave wheel set are arranged horizontally opposite each other. The gap between the driving concave wheel set and the follower concave wheel set is used to nest the vertical rebar 23. The climbing motor 4 is mounted on the climbing frame and connected to the driving concave wheel set to drive the driving concave wheel set to move axially along the vertical rebar. The driving concave wheel set and the follower concave wheel set are arranged opposite each other to clamp the vertical rebar 23. When the climbing motor 4 drives the driving concave wheel set to move, the driving concave wheel set and the follower concave wheel set move up and down axially along the vertical rebar 23 simultaneously, causing the climbing frame to move up and down axially along the vertical rebar 23.

[0022] Furthermore, the drive concave wheel assembly includes at least one pair of drive concave wheels 3 spaced apart vertically, the drive concave wheels 3 being slidably nested inside one side of the climbing frame, and the follower concave wheel assembly includes at least one pair of follower concave wheels 12 spaced apart vertically, the follower concave wheels 12 being slidably nested inside the other side of the climbing frame, the follower concave wheels 12 and the drive concave wheels 3 being used to slidably nest the vertical reinforcing bars 23, and a climbing motor 4 is connected to at least one drive concave wheel 3.

Both the driving concave wheels 3 and the following concave wheels 12 are slidably connected to the climbing frame via a rotating shaft. Bearings are nested at both ends of the rotating shaft, and the bearings are nested within the climbing frame. A climbing motor 4 is installed on the outer periphery of the climbing frame, opposite to each driving concave wheel 3. The output end of the climbing motor 4 is connected to one end of the rotating shaft of the driving concave wheel 3. One end of the rotating shaft is connected to the climbing motor 4 via a coupling, and the climbing motor 4 is equipped with a reducer.

[0024] Furthermore, the climbing frame includes a hinged mounting plate 11, a climbing mounting plate 2, and a hinge buckle 5. The hinged mounting plate 11 and the climbing mounting plate 2 are arranged at intervals relative to each other. One side of the hinged mounting plate 11 has a slidingly nested follower concave wheel 12, and one side of the climbing mounting plate 2 has a slidingly nested drive concave wheel 3. The outer periphery of the hinged mounting plate 11 and the climbing mounting plate 2 is provided with hinge buckles 5 for connecting the two. The other side of the climbing mounting plate 2 is connected to a vertical lifting mechanism.

[0025] Specifically, both the hinge mounting plate 11 and the climbing mounting plate 2 are rectangular. They are spaced apart and positioned opposite each other. Hinges 5 are installed at the top and bottom ends of the same side of both the hinge mounting plate 11 and the climbing mounting plate 2, allowing for opening and closing. After connecting the hinge mounting plate 11 and the climbing mounting plate 2 via the hinges 5, they are secured with locking bolts 13.

[0026] Furthermore, the vertical lifting mechanism includes a trough frame 6, a lifting bracket 7, and a drive assembly. One side of the trough frame 6 is connected to the climbing frame, and the other side of the trough frame 6 is slidably connected to the lifting bracket 7. The drive assembly is located on the other side of the trough frame 6 and connected to the lifting bracket 7. The drive assembly is used to drive the lifting bracket 7 to move axially along the trough frame 6. A horizontal telescopic mechanism is located on the lifting bracket 7.

[0027] Specifically, the trough-shaped frame 6 is a rectangular body, and one side of the trough-shaped frame 6 is connected to the climbing fixed plate frame 2. U-shaped grooves are provided on both sides of the trough-shaped frame 6, and the U-shaped grooves are arranged vertically along the axial direction of the trough-shaped frame 6. The lifting support 7 is a U-shaped frame body, and one end of the lifting support 7 is looped around both sides of the trough-shaped frame 6 and slidably connected to the U-shaped groove.

[0028] Furthermore, the drive assembly includes a lifting motor 8, a rack 9, and a gear 10. The lifting motor 8 is mounted on the lifting bracket 7, the rack 9 is axially mounted on the other side of the slotted frame 6, and the gear 10 is sleeved on the output end of the lifting motor 8 and meshes with the rack 9. Roller sets are slidably connected to both opposite ends of one side of the lifting bracket 7, and the roller sets are slidably nested on the outer periphery of the slotted frame 6.

[0029] Specifically, the roller assembly consists of several rollers 17 spaced apart. One end of each roller 17 is axially slidably connected to the lifting bracket 7 via a bearing. The outer periphery of each roller 17 is nested in a U-shaped groove. When the lifting motor 8 drives the gear 10 to move along the rack 9, the roller 17 slides axially along the U-shaped groove.

[0030] Furthermore, the horizontal telescopic mechanism includes a smooth rod 18, a sliding sleeve 19, and an electric push rod 21. The smooth rod 18 is mounted on the lifting bracket 7, and the sliding sleeve 19 is slidably connected to the smooth rod 18. An electric push rod 21 is mounted on one side of the lifting bracket 7. One end of the electric push rod 21 is hinged to the lifting bracket 7, and the other end is hinged to the sliding sleeve 19. A compression cylinder 22 is mounted on the sliding sleeve 19.

[0031] Specifically, the upper end of the lifting bracket 7 has a support plate with flanges at both ends. The smooth rod 18 is positioned at both ends of the flanges on the support plate, with one end extending towards the vertical reinforcing bar 23. One end of the electric push rod 21 is hinged to the support plate. The extension and retraction of the electric push rod 21 drives the sliding sleeve 19 to move axially along the smooth rod 18, causing the pressing cylinder 22 to move towards the vertical reinforcing bar 23. A hinge shaft 20 is provided at the upper end of the sliding sleeve 19, and the pressing cylinder 22 is located at the upper end of the hinge shaft 20. The hinge shaft 20 is vertically mounted on the sliding sleeve 19 and slidably connected to it, allowing the hinge shaft 20 to rotate axially to adjust the relative position of the pressing cylinder 22 and the vertical reinforcing bar 23.

[0032] Furthermore, the vertical lifting mechanism also includes casters 1, which are connected to the bottom of the trough-shaped frame 6. The casters 1 are omnidirectional wheels, which facilitate the movement of the entire device.

[0033] Furthermore, a height displacement sensor 15 is installed on the vertical lifting mechanism to detect the moving distance of the lifting support 7; a horizontal distance sensor 16 is installed on the horizontal telescopic mechanism to detect the horizontal distance between the extrusion cylinder 22 and the vertical reinforcing bar 23. The height displacement sensor 15 controls the axial displacement of the extrusion cylinder 22 along the vertical reinforcing bar 23 to determine the extrusion length of the extrusion cylinder 22, and the horizontal distance sensor 16 controls the horizontal radial distance between the extrusion cylinder 22 and the vertical reinforcing bar 23.

[0034] Specifically, the height displacement sensor 15 is a photoelectric displacement sensor, consisting of a transmitter and a receiver. The transmitter is mounted on the lifting support 7, and multiple receivers are axially spaced sequentially on the channel frame 6, with different receiver positions corresponding to different distances. When the lifting support 7 moves up and down, the transmitter sequentially connects with different receivers to detect different distances. The height displacement sensor 15 sequentially detects the movement distance of the lifting support 7 along the channel frame 6, thereby determining the axial displacement of the extrusion cylinder 22 along the vertical reinforcing bar 23. The horizontal distance sensor 16 is a laser rangefinder. The horizontal distance sensor 16 controls the extension and retraction distance of the electric push rod 21, thereby obtaining the horizontal radial distance between the extrusion cylinder 22 and the vertical reinforcing bar 23, to control the extrusion cylinder 22 to extrude the reinforcing bar sleeve 14. The height displacement sensor 15 controls the movement distance of the lifting support 7 by controlling the climbing motor 4.

[0035] Furthermore, a controller is installed on the trough-shaped frame 6, which is electrically connected to the extrusion cylinder 22, the climbing motor 4, the lifting motor 8, the electric push rod 21, the height displacement sensor 15, and the horizontal distance sensor 16. The controller can achieve automatic control of the extrusion cylinder 22, the climbing motor 4, the lifting motor 8, and the electric push rod 21 through PLC programming. PLC programming is prior art and will not be described in detail here.

[0036] In use, the device is first moved to the outer periphery of the vertical reinforcing bar 23 by the moving wheel 1. The reinforcing bar sleeve 14 is pre-fitted onto the vertical reinforcing bar 23. The locking bolt 13 is loosened and the hinge buckle 5 is opened. The hinge plate frame 11 and the climbing plate frame 2 of the climbing frame are respectively fitted onto the outer periphery of the vertical reinforcing bar 23. Then the hinge buckle 5 and the locking bolt 13 are locked. The climbing motor 4 is controlled by the controller to drive the climbing frame to the pre-compression position of the vertical reinforcing bar 23. Then the electric push rod 21 is controlled to move horizontally to drive the compression cylinder 22 to move toward the vertical reinforcing bar 23 to encircle the vertical reinforcing bar 23. The horizontal extension distance of the electric push rod 21 is detected by the horizontal distance sensor. Then the lifting motor 8 is controlled to drive the compression cylinder 22 to rise to the upper position of the reinforcing bar sleeve 14. The compression cylinder 22 is started. At the same time, the lifting motor 8 is controlled to drive the lifting bracket 7 to move axially along the channel frame 6 so that the compression cylinder 22 compresses the reinforcing bar sleeve 14. The compression distance is detected and determined by the height displacement sensor 15.

[0037] After extrusion is completed, the electric push rod 21 drives the extrusion cylinder 22 to disengage from the vertical steel bar 23 and return to its original position. The lifting motor 8 drives the lifting bracket 7 to return to its original position, and the climbing motor 4 drives the climbing frame to return to its original position. Then, the hinge buckle 5 is opened, the locking bolt 13 is removed, and the climbing frame is disengaged from the vertical steel bar 23. Finally, the moving device is moved to the outer periphery of the next vertical steel bar 23 by the moving wheel 1 to continue construction.
