Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe breaking devices, and particularly relates to a breaking device applied to disassembling steel pipe fittings. Background Art

[0002] In the current construction, machinery and material handling industries, steel pipe fittings are widely used due to their excellent physical properties and wide application range. In some building demolition or renovation projects, it is necessary to quickly and accurately cut and remove old steel pipes, and the removed steel pipes also need to be cut into smaller sections for convenient subsequent transportation, storage and reuse. However, the existing metal hydraulic pliers are large in size and vibrate during use, resulting in uncontrollable cutting positions, requiring greater force to control, and unable to guarantee cutting accuracy.

[0003] Chinese patent document CN218168845U discloses a labor-saving hydraulic breaking device. By unfolding connecting rod A, connecting rod A drives the roller to flip to one side of the hydraulic shear body. By rotating support rod B, the threaded rod is threadedly connected with the threaded groove to fix two connecting rod A and support two rollers. When carrying the hydraulic shear body, place the rollers on the ground and pull the hydraulic shear body to save the force consumed during the handling process, so that the operator has enough strength to use the hydraulic breaking device to remove items. Although the above breaking device solves the handling problem of the breaking device, during the breaking operation, it is still necessary to hold the breaking device for operation, and the breaking accuracy cannot be controlled, and it will consume more strength of workers. Therefore, the utility model proposes a breaking device applied to disassembling steel pipe fittings that can be fixed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a breaking device applied to disassembling steel pipe fittings, which can position and fix the cutting point, avoid the movement of the device during breaking, improve the breaking accuracy, and reduce the working difficulty at the same time.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A breaking device applied to disassembling steel pipe fittings includes a housing. A base is coaxially arranged at the bottom of the housing. A breaking device and a clamping device are arranged on the housing. The breaking device includes a first driving device and two breaking arms. The breaking arms are hinged to the top of the housing through pins, and the breaking arms are hinged to the first driving device through connecting pieces. The clamping device includes a second driving device and two clamping arms. The clamping arms are hinged to the top of the housing through pins, and the clamping arms are hinged to the second driving device through connecting pieces. The two breaking arms and the two clamping arms are arranged in parallel.

[0007] As a preferred technical solution, a handle is fixedly arranged outside the housing.

[0008] As a preferred technical solution, the first driving device includes a hydraulic cylinder, a first transmission shaft and a support. The hydraulic cylinder is fixedly arranged in the housing. The first transmission shaft is fixedly connected to the output end of the hydraulic cylinder. The support is fixedly arranged at one end of the first transmission shaft away from the hydraulic cylinder. The support is of a Y-shaped structure. The two branch ends of the Y-shaped structure of the support are respectively hinged to one end of a connecting member, and the other end of the connecting member is hinged to the demolition arm.

[0009] As a preferred technical solution, two long grooves are symmetrically formed in the upper side wall of the housing. The long grooves match the two Y-shaped branch ends of the support, and the two Y-shaped branch ends of the support can move left and right in the long grooves.

[0010] As a preferred technical solution, the second driving device includes a double-acting cylinder and two second transmission shafts. The double-acting cylinder is fixedly arranged on the outer side wall of the housing. The two second transmission shafts are respectively fixedly connected to the two output ends of the double-acting cylinder. One end of the second transmission shaft away from the double-acting cylinder is hinged to one end of a connecting member, and the other end of the connecting member is hinged to the clamping arm.

[0011] As a preferred technical solution, a clamping pad is detachably arranged on the clamping surface of the clamping arm.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, the clamping device and the demolition device are arranged in parallel. The clamping device can first position and fix the cutting point and then perform the demolition operation, which improves the accuracy of the demolition position and does not require manual holding and fixing during the demolition process, reducing the working intensity of workers. At the same time, since the whole device is clamped and fixed on the steel pipe, the device will not move during the demolition, avoiding unnecessary damage. BRIEF DESCRIPTION OF THE DRAWINGS
