Description

Technical Field

[0001] The utility model relates to the technical field of pipe pile cutting equipment, in particular to a clamp-type pipe pile cutting device. Background Art

[0002] Hoop-type pile cutters are widely used in the process of cutting prefabricated pile heads. Before cutting the pile, the existing hoop-type pile cutters manually draw a mark line on the pile body, then adjust the pile cutter to the specified position and fasten it to the pile body through the hoop device. The handle on the pile cutter is then manually operated to bring the cutter disc close to the pile head to perform the cutting operation. During the pile cutting process, the operator needs to continuously control the pile cutter to cut based on experience.

[0003] The existing clamp-type pile cutter matches the cutter disc and the cutting mark line by adjusting the installation position of the pile cutter on the pile body. The matching accuracy is poor and it is time-consuming and labor-intensive. After the clamp is fixed, the cutting height cannot be adjusted according to actual needs. At the same time, a large amount of dust is generated during the pile cutting process, and the operator needs to pull a water pipe to reduce the dust during the pile cutting process. As a result, the pile cutting process requires the cooperation of multiple people, which increases the manpower and material costs of the pile cutting process. Utility Model Content

Compared with realizing the position adjustment of the cutting mechanism by changing the installation position of the clamp mechanism, the device has higher precision and higher adjustment efficiency. At the same time, a dust reduction mechanism is provided on the clamp mechanism, which eliminates the need for an operator to pull a water pipe to perform dust reduction treatment during the cutting process, making the pile cutting process easier to operate and reducing the manpower and material costs of the pile cutting process.

[0016] Preferably, the dust suppression mechanism includes a water tank and a water channel. The water channel is disposed within the clamp mechanism, and the clamp mechanism is provided with a water outlet connected to the water channel. The water outlet is connected to a diversion pipe.

[0044] like Figure 1-Figure 5 As shown, a clamp-type pipe pile cutting device includes a clamp mechanism 1, a guide mechanism 3, a dust reduction mechanism, a climbing mechanism 5, a driving mechanism 7 and a cutting mechanism 6.

[0045] like Figure 5 As shown, the clamp mechanism 1 is used to fix the cutting device on the pile to be cut. The clamp mechanism 1 in this embodiment can be consistent with the existing technical structure. The clamp mechanism 1 can include a sliding frame that is slidably arranged. The sliding frame can slide along the circumference of the clamp mechanism 1 to achieve the connection between the clamp mechanism 1 and the guide mechanism 3.

[0046] In an optional embodiment, a rotating shaft 2 can be set on the sliding frame, and the rotating shaft 2 is consistent with the central axis direction of the clamping mechanism 1. The sliding frame and the guide mechanism 3 can be connected to the rotating shaft 2 respectively, thereby realizing the hinged connection of the guide mechanism 3 relative to the clamping mechanism 1.

[0047] In an optional embodiment, the clamp mechanism 1 may include two clamping arms that are hingedly connected, with one end of the two clamping arms being hinged and the other end being fixed with bolts.

[0048] like Figure 2 As shown, the guide mechanism 3 is used to realize the height adjustment of the cutting mechanism 6 in the axial direction of the clamping mechanism 1. The cutting mechanism 6 is arranged on the climbing mechanism 5.

The first guide portion 32 and the second guide portion 52 are slidably engaged with each other. The guide plate 31 and the mounting plate 51 may be arranged in parallel. The mounting plate 51 is primarily used to mount the cutting mechanism 6, and the guide plate 31 is primarily used to achieve slidable engagement with the mounting plate 51 equipped with the cutting mechanism 6.

[0052] In an optional embodiment, the driving mechanism 7 may include a worm gear lifting mechanism.

[0053] In an optional embodiment, the worm gear lifting mechanism may include a screw 71, a worm gear 72, and a worm gear 73. Both ends of the screw 71 are rotatably connected to the guide plate 31. The worm gear 72 is threadedly engaged with the screw 71, and the worm gear 73 is meshed with the worm gear 72. The worm gear 73 extends out of the mounting plate 51, and one end of the worm gear 73 extending out of the mounting plate 51 is connected to an adjustment handwheel 74. The mounting plate 51 can be moved relative to the guide plate 31 by rotating the adjustment handwheel 74. The threaded connection between the worm gear 72 and the screw 71 and the meshing of the worm gear 73 and the worm gear 72 can lock the height of the mounting plate 51 relative to the guide plate 31, thereby achieving stable adjustment of the mounting plate 51.

[0054] like Figure 2As shown, the cutting mechanism 6 has a structure similar to that of an existing pile cutting device and may include a motor 61, a transmission mechanism 62 and a cutter disc 63 connected in sequence. The transmission mechanism 62 may be a belt transmission mechanism 62, which is arranged on the top of the mounting plate 51. The cutter disc 63 is arranged at the bottom of the mounting plate 51. The cutter disc 63 and the transmission mechanism 62 are connected via a transmission shaft 64. The transmission shaft 64 may be arranged on the side of the mounting plate 51 close to the clamping mechanism 1 and at the end away from the clamping mechanism 1. A protective box 53 adapted to the cutter disc 63 is provided at the bottom of the side of the mounting plate 51 away from the clamping mechanism 1. An operating handle 54 is provided laterally in the middle of the side of the mounting plate 51 away from the clamping mechanism 1. By holding the operating mechanism, the cutting mechanism 6 can be operated to move closer to or further away from the pile body.

[0055] In an optional embodiment, in order to avoid positional interference between the screw rod 71 and the transmission mechanism 62, the screw rod 71 can be set at one end of the mounting plate 51 close to the clamping mechanism 1, the screw rod 71 is set vertically and offset from the transmission mechanism 62, the top and bottom ends of the screw rod 71 are respectively rotatably connected to the connecting plate set on the guide plate 31 through bearings, the turbine 72 is coaxially threadedly connected to the screw rod 71, and the worm 73 is rotatably connected to the mounting plate 51 through a bearing, one end extends between the mounting plate 51 and the guide plate 31 to engage with the turbine 72, and the other end extends out of the mounting plate 51 to connect to the adjusting handwheel 74. By rotating the adjusting handwheel 74, the turbine 72 can be driven to rotate. With the cooperation of the threaded connection between the turbine 72 and the screw rod 71, the turbine 72 moves along the axial direction of the screw rod 71, thereby realizing the relative movement adjustment of the mounting plate 51 and the guide plate 31.

[0056] In an optional embodiment, the connecting plate provided on the guide plate 31 may be a plate-shaped structural member provided at the upper and lower ends of the guide plate 31 , and may be an integral structural member with the guide plate 31 .

[0057] In an optional embodiment, a mounting box 55 can be provided on the mounting plate 51, and the worm 72 and the worm 73 can be located in the mounting box 55, and the screw 71 vertically passes through the mounting box 55. The mounting box 55 is used to limit the relative movement of the worm 72 and the mounting plate 51, maintain the meshing state of the worm 72 and the worm 73, so that when the adjusting hand wheel 74 is rotated, the relative position of the worm 72 and the worm 73 and the mounting plate 51 is fixed, and the whole moves with the screw 71.

[0058] In an optional embodiment, the mounting box 55 can be a plate-shaped structural member with a notch vertically arranged on the side of the mounting plate 51, which can be clamped on the screw rod 71 and can abut the upper and lower end surfaces of the turbine 72.

[0059] In one or several embodiments, a scale marking portion 8 can be further provided between the guide plate 31 and the mounting plate 51, and an indication portion 81 can be provided on the mounting plate 51. The indication portion 81 can correspond to the scale marking portion 8, so that the displacement of the mounting plate 51 relative to the guide plate 31 can be accurately read through the cooperation between the indication portion 81 and the scale marking portion 8, thereby further improving the position adjustment accuracy of the cutting mechanism 6.

[0060] In an optional embodiment, the scale marking portion 8 can be a scale provided on the guide plate 31, and the indicating portion 81 can be a pointer, a window or other structure that can cooperate with the scale to realize reading provided on the mounting plate 51, such as Figure 3 As shown, an indicator portion 81 of a window structure is provided on the mounting plate 51 , and the scale on the scale can be observed through the indicator portion 81 of the window structure.

[0061] The dust reduction mechanism is a mechanism used to reduce dust during the pile cutting process.

[0062] In this embodiment, the dust reduction mechanism may include a water tank 4 and a water channel 11. The water channel 11 may be disposed within the clamp mechanism 1. The clamp mechanism 1 may include a water outlet connected to the water channel 11. The water outlet may be connected to a flow guide pipe 12. The water flowing through the water channel 11 can evenly disperse dust reduction around the pile body, resulting in a better dust reduction effect.

[0063] In an optional embodiment, the water tank 4 can be placed on the top of the clamp mechanism 1 or the top of the pile body to provide water for the dust reduction mechanism. The water tank 4 can also be set on the ground and connected to a power mechanism such as a water pump according to actual conditions to achieve water supply.

[0064] In an optional embodiment, the water delivery channel 11 can be provided in the clamping arm, and the water outlet can be provided at the bottom of the clamping arm, so that the water flow outputted through the water outlet is concentrated on the wall around the pile body to reduce dust.

The water flow of the guide pipe 12 can contact the outer wall of the pile body, thereby achieving dust reduction treatment on the pile body and improving the dust reduction effect.

[0066] In an optional embodiment, the number of water outlets can be set to multiple, and the multiple water outlets can be evenly distributed around the pile body, so that the guide pipe 12 can fully reduce dust on the side wall of the pile body, and the dust reduction effect is better.

[0067] In one or more embodiments, Figure 1As shown, it also includes a pile core embedded frame 9, which is set in the pile core when cutting the pile to improve the installation stability of the cutting device and the pile. The pile core embedded frame 9 is provided with a structural part extending outside the pile, and a through hole that can cooperate with the pin shaft 91 hole on the clamp mechanism 1 is provided, so that the pile core embedded frame 9 can be connected to the clamp mechanism 1 through the pin shaft 91, making the cutting process more stable and smooth.

[0068] The clamp-type pipe pile cutting device of this embodiment is used. When the clamp mechanism 1 is fixed to the pile to be cut, the climbing mechanism 5 and the guide mechanism 3 are relatively moved by the driving mechanism 7 to adjust the position of the cutting mechanism 6 on the climbing mechanism 5 in the axial direction of the pile body so that the cutting mechanism 6 corresponds to the cutting position set on the pile body. The cutting mechanism 6 and the dust reduction mechanism are started, and the operating handle 54 is manually grasped to drive the cutting mechanism 6 close to the pile body to achieve dust reduction cutting. The position of the cutting mechanism 6 is adjusted along the circumference of the clamp mechanism 1 according to actual conditions to achieve complete cutting of the pipe pile.

[0069] A clamp-type pipe pile cutting device in this embodiment drives the climbing mechanism 5 and the guide mechanism 3 to move relative to each other through the driving mechanism 7, thereby realizing the position adjustment of the cutting mechanism 6 on the climbing mechanism 5 relative to the pile body. Compared with realizing the position adjustment of the cutting mechanism 6 by changing the installation position of the clamp mechanism 1, the device has higher precision and higher adjustment efficiency. At the same time, a dust reduction mechanism is provided on the clamp mechanism 1, eliminating the need for the operator to pull a water pipe to perform dust reduction treatment during the cutting process, making the pile cutting process easier to operate and reducing the manpower and material costs of the pile cutting process.
