Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutter-spreader technology, specifically a portable airborne cutter-spreader. Background Technology
[0002] In emergency rescue, engineering demolition, and other fields, the portability of the spreader is crucial as a key piece of equipment that combines cutting and expansion functions. However, traditional spreaders are mostly operated manually, requiring continuous handholding during operation, which has the following significant drawbacks:
[0003] High labor intensity: Handheld operation requires applying gripping force throughout the entire process. Especially in heavy-duty operations such as shearing and spreading, operators are prone to fatigue and find it difficult to support long-term continuous work.
[0004] Limited operational efficiency: Insufficient stability of manual grip may lead to deviations in shearing / expansion accuracy, and frequent operator changes are required, affecting rescue or project progress.
[0005] Limited applicability: Manual handheld operation poses safety risks in dangerous or complex environments such as high altitudes and deep foundation pits, and it is difficult to meet the automated operation requirements of airborne equipment (such as excavators and cranes).

[0011] Preferably, the lower connecting frame includes a lower connecting plate, which is fixed on the mounting plate. A fixing sleeve is fixed to the side wall of the lower connecting plate. The fixing sleeve is sleeved on the outside of the hydraulic cylinder telescopic rod. A connecting hole three is provided at the end of the fixing sleeve for hinged connection of the claw plates on the main body of the shear spreader.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] The portable airborne cutter and spreader provided by this utility model, through optimized structural design, effectively solves the problems of high labor intensity, low operating efficiency, and limited applicable scenarios of traditional handheld cutters and spreaders, significantly improving the practicality and automation level of the equipment. The specific beneficial effects are as follows:
[0014] 1) Reduce labor intensity: The machine-mounted design allows it to be connected to excavators, cranes and other equipment via the attachment joint assembly, eliminating the need for manual hand operation. This avoids fatigue caused by continuous gripping of equipment during heavy-duty operations and effectively reduces labor intensity.
[0015] 2) Improved operational accuracy and efficiency: The equipment is mounted on an airborne platform and operated under mechanical control, resulting in greater stability and reducing deviations in shearing / expansion accuracy caused by unstable manual handling. Furthermore, the elimination of frequent operator changes helps ensure rescue or project progress and improves operational efficiency.
[0016] 3) Expanding applicable scenarios: It is suitable for dangerous or complex environments such as high altitudes and deep foundation pits, breaking through the safety risks and limitations of traditional manual hand-held operation in these scenarios, meeting the automated operation needs of airborne equipment, and broadening the application scope of the shear spreader.
[0017] 4) Reliable and stable connection: The connecting pin of the attachment joint assembly is locked by a stop ring and a locking bolt, which can effectively prevent the axial movement and rotation of the connecting pin, ensuring a reliable and stable connection between the shear spreader and the on-board equipment, and ensuring the safety of the operation process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1 and 2 As shown, a portable airborne splitter includes a splitter body 1. The cylinder body of the splitter body 1 is fixedly connected to an upper connecting frame 3 and a lower connecting frame 2. The lower connecting frame 2 is sleeved on the outside of the telescopic rod of the cylinder and hinged to the claw plate on the splitter body 1. The upper connecting frame 3 is sleeved on the outside of the cylinder body and completely covers the cylinder body. An attachment joint assembly 4 is fixedly connected to one end of the upper connecting frame 3 near the tail of the cylinder.
[0027] like Figure 2 As shown, the main body 1 of the splitter includes a hydraulic cylinder, and an mounting plate 11 is provided at the end of the hydraulic cylinder for connecting the upper connecting frame 3 and the lower connecting frame 2. The telescopic rod of the hydraulic cylinder connects two connecting rods, and each connecting rod connects to a claw plate.
[0028] like Figure 2 and 4 The lower connecting frame 2 is sleeved on the outside of the telescopic rod of the oil cylinder. Its bottom is fixedly connected to the mounting plate 11 on the cylinder body through the lower connecting plate 21. The fixing sleeve 22 on the side wall is tightly sleeved on the outside of the telescopic rod of the oil cylinder. The connecting hole 3 23 at the end is used to hinge the claw of the shear spreader body 1.
[0029] refer to Figure 2 and 5The upper connecting bracket 3 completely covers the cylinder body through the cylinder cover 31. One end of the connecting hole 32 is bolted to the mounting plate 11, and the other end of the upper connecting plate 33 is fixedly connected to the attachment joint assembly 4 through the connecting hole 34.
[0030] refer to Figure 2 and Figure 5 The attachment joint assembly is installed by aligning the connecting holes 34 of the base plate 41 and the upper connecting plate 33, and then fixing them together with bolts. A connecting pin 43 is installed between the two side plates 42 at the far end of the base plate 41. The pin holes of the side plates 42 are clearance-fitted with the connecting pin 43. A stop ring 44 is welded to the pin hole of one of the side plates 42. After the connecting pin 43 is inserted, the end of the connecting pin 43 is embedded in the stop ring 44.
