[0044] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention. Example 1

[0045] This embodiment provides a clamp for a pier column climbing device, which can be used in cap beam construction.

[0046] Reference Figures 1 to 4 The pier climbing device described in this embodiment includes:

[0047] Upper clamp and lower clamp, the upper clamp and lower clamp are arranged vertically on a pier column 100;

[0048] Upper connecting seat 21, the upper clamp is installed in the inner cavity of the upper connecting seat 21;

[0049] The lower connecting seat 27, wherein the lower clamp is installed in the inner cavity of the lower connecting seat 27;

[0050] A linear motion output device 200 is used to change the distance between an upper connecting seat 21 and a lower connecting seat 27 on a pier 100. The linear motion output device 200 includes an active end and a passive end. The active end drives the passive end to output linear motion. One of the active end and the passive end is hinged to the upper connecting seat, and the other is hinged to the lower connecting seat, and the axes of the hinges are parallel.

[0051] In this embodiment, the linear motion output device 200 is hinged to both the upper connecting seat 21 and the lower connecting seat 27. This allows the linear motion output device 200 to primarily bear vertical forces, and is largely unaffected by lateral forces caused by the off-center loads of the upper connecting seat 21 and the lower connecting seat 27. This simplifies the force distribution, and the pier climbing device is less likely to jam against the pier 100 during ascent or descent. Furthermore, compared to the previous rigid chain structure, the pier climbing device provided in this embodiment is more cost-effective.

[0052] In this embodiment, four sets of linear motion output devices 200 are provided. Each set of linear motion output devices 200 is symmetrically distributed relative to the axis center of the pier 100, and the hinge axes in each set of linear motion output devices 200 are parallel.

[0053] By setting multiple sets of linear motion output devices 200, the pier climbing device can be made more balanced, and on the other hand, the load on each set of linear motion output devices 200 can be reduced.

[0054] In this embodiment, the active end of the linear motion output device 200 includes a gear 28 and a power device 37 that drives the gear 28 to rotate; the passive end of the linear motion output device 200 includes a rack 29 that meshes with the gear 28.

[0055] The shaft for mounting gear 28 is mounted on upper connecting seat 21 via bearing seat 31. Rack 29 is mounted on rack box 39. The lower end of rack box 39 is mounted on lower connecting seat 27 via hinge seat. The axis of bearing seat 31 is parallel to the axis of hinge seat.

[0056] In this embodiment, linear motion output is achieved through the meshing transmission of gears and racks. The gap between the gears and racks is small. When the upper clamp is locked and the lower clamp is loosened, the gear of the lower connecting seat 27 will only fall down by 1-2mm due to the meshing gap of the rack. Therefore, the impact force of the lower clamp on the lower connecting seat is greatly reduced. In addition, the contact area between the gears and racks is large, resulting in better force distribution and greater safety.

[0057] In this embodiment, Figure 1 The two linear motion output devices 200 on the left side are driven by a power device 37, and the two linear motion output devices 200 on the right side are driven by a power device 37. This makes it easier to ensure the synchronization of the four linear motion output devices 200, thereby improving the levelness of the upper connecting seat 21 and the lower connecting seat 27 and ensuring the load-bearing safety of the pier column climbing device for the cap beam construction equipment and device.

[0058] In this embodiment, the pier climbing device also includes a guide device for adjusting the distance between the rack 29 and the gear 28;

[0059] The guide device and the bearing housing 31 are installed together on the upper connecting seat 21;

[0060] The guiding device includes:

[0061] Camshaft 3602 is mounted together with bearing housing 31 on upper connecting seat 21;

[0062] Cam 3603 has a cylindrical surface and is mounted on camshaft 3602, but the axis of cam 3603 does not coincide with that of camshaft 3602;

[0063] The cylindrical body 3601 is mounted on the cam 3603 by a bearing, and the cylindrical body 3601 rolls on the side of the rack box 39 where the rack 29 is not mounted.

[0064] By setting a guide device including cam 3603, the gap between the gear and rack can be adjusted to ensure the guiding function of the guide device.

[0065] In this embodiment, the cylindrical body 3601 has flanges 360101 at both ends. The flanges 360101 are bent in a direction away from the axis of the cylindrical body 3601. The rack box 39 is located between the flanges 360101 at both ends. The flanges 360101 play a limiting and guiding role for the rack box 39 in the horizontal direction.

[0066] In this embodiment, the camshaft 3602 is mounted between two connecting plates 30. Besides the hole through which the camshaft passes, the connecting plate 30 also has a through hole, through which the shaft of the gear 28 passes. Figure 2 As can be seen from the image, in this embodiment, the connecting plate 30 is supported and fixed by placing the bottom edge of the connecting plate 30 directly onto the bearing seat 31.

[0067] In this embodiment, both the guide device and the gear 28 are mounted on the connecting plate 30. This ensures that the plane containing the common axis of rotation of the camshaft 3602 and the gear 28 is perpendicular to the length direction of the rack 29. This ensures that the rack box 39 can bear force in the form of a two-force bar, preventing the rack box 39 from being subjected to lateral forces caused by platform off-center loading. The rack 29 only bears forces along its length and a small amount of lateral forces between the gear and rack, simplifying the force distribution. Compared to structures that fix both ends of the rack 29, the rack box 39 structure is more compact, reduces costs, and allows the overall pier climbing equipment to operate more stably.

[0068] In this embodiment, an anti-drop limit switch detection block 3801 is installed at the upper end of the rack box 39; and a first limit switch 3802 and a second limit switch 3803 are provided on the connecting plate 30, with the first limit switch 3802 being higher than the second limit switch 3803.

[0069] When the anti-drop limit switch detection block 3801 touches the first limit switch 3802, the relative speed of the movement between the upper connecting seat 21 and the lower connecting seat 27 decreases;

[0070] When the anti-drop limit switch detection block 3801 touches the second limit switch 3803, the relative movement between the upper connecting seat 21 and the lower connecting seat 27 stops.

[0071] By setting the first limit switch 3802 and the second limit switch 3803, the rack 29 is prevented from completely disengaging from the gear 28 and tipping over. Furthermore, by setting the first limit switch 3802 and the second limit switch 3803 to the upper and lower positions, the speed can be gradually controlled to prevent excessive speed changes and inertia-induced impacts between the teeth.

[0072] from Figure 3 As can be seen from this embodiment, a stop block is also fixed at the upper end of the rack box 39 to further prevent the rack 29 from completely disengaging from the gear 28 and tipping over.

[0073] Continue to refer to Figure 3In order to prevent collisions between the upper connecting seat 21 and the lower connecting seat 27 and between the devices installed on them, in this embodiment, an anti-collision limit switch detection block 4001 is installed near the lower end of the rack box 39; and a third limit switch 4002 and a fourth limit switch 4003 are provided on the connecting plate 30, with the third limit switch 4002 being higher than the fourth limit switch 4003.

[0074] When the anti-collision limit switch detection block 4001 touches the fourth limit switch 4003, the relative speed of the movement between the upper connecting seat 21 and the lower connecting seat 27 decreases.

[0075] When the anti-collision limit switch detection block 4001 touches the third limit switch 4002, the relative movement between the upper connecting seat 21 and the lower connecting seat 27 stops.

[0076] By setting the upper and lower positions of the third limit switch 4002 and the fourth limit switch 4003, the speed can be gradually controlled to prevent excessive speed changes and inertia-induced impacts between the teeth.

[0077] In this embodiment, the rack box 39 and the lower connecting seat 27 are hinged by a spherical bearing, which can reduce the requirements for processing and save processing costs.

[0078] In this embodiment, the pier climbing device further includes:

[0079] Pier rollers 35 are installed on the lower surface of the upper connecting seat 21 and the upper surface of the lower connecting seat 27. The pier rollers 35 installed on the lower surface of the upper connecting seat 21 are symmetrically distributed with respect to the axis center of the pier 100. The pier rollers 35 installed on the upper surface of the lower connecting seat 27 are also symmetrically distributed with respect to the axis center of the pier 100. The axis of the pier rollers 35 is horizontal.

[0080] Furthermore, the distance between the axis of the pier roller 35 and the pier 100 is adjustable, so that the pier roller 35 rolls on the pier 100 when the pier climbing device rises or falls.

[0081] In the technical solution provided in this embodiment, the gear 28 and the upper connecting seat 21 are hinged, and the rack 29 and the lower connecting seat 27 are hinged, so that the gear and rack mainly bear the vertical force and can also bear a certain lateral force. In this embodiment, by setting the position adjustable pier roller 35, the pier roller 35 can provide the pier climbing device with accurate and reliable lateral force, and can bear most of the lateral force without the need for other lateral force bearing structures like scissors, thus ensuring that the pier climbing device rises and falls smoothly.

[0082] To guide the movement between the upper connecting seat 21 and the lower connecting seat 27, the pier climbing device in this embodiment also includes a pin 33 and a pin cylinder 34. The pin is installed on the lower surface of the upper connecting seat 21, and the pin cylinder 34 is installed on the upper surface of the lower connecting seat 27.

[0083] The inner diameter of the pin cylinder 34 is equal to the outer diameter of the pin 33, and the lower end of the pin 33 has a tapered surface to facilitate its insertion into the pin cylinder 34.

[0084] Furthermore, the pin cylinder 34 has a certain height, and when the pin 33 is fully inserted into the pin cylinder 34, it can also limit the distance between the upper connecting seat 21 and the lower connecting seat 27.

[0085] Example 2

[0086] Reference Figure 5 The difference between this embodiment and embodiment 1 is that the active end of the linear motion output device includes a cylinder barrel 40 of a hydraulic cylinder and a hydraulic pump connected to the inner cavity of the cylinder barrel; the passive end of the linear motion output device includes a cylinder rod 41 located inside the cylinder barrel 40.

[0087] The cylinder 40 is hinged to the upper connecting seat 21, and the end of the cylinder rod 41 is hinged to the lower connecting seat 27.

[0088] In this embodiment, the linear motion output device, which includes the cylinder barrel 40 and cylinder rod 41 of the hydraulic cylinder, has a simpler gear and rack arrangement, requires fewer non-standard parts to be processed, has lower manufacturing costs, and is easier to install than the gear and rack arrangement in Embodiment 1.
