Description

Technical Field

[0001] This utility model belongs to the field of loader technology, specifically relating to a clamp body welding component and clamping tool suitable for loaders. Background Technology

[0002] Loaders are a common type of construction machinery, widely used in loading, unloading, handling, and stacking various materials. Loaders complete various operations such as shoveling and unloading by controlling a series of actions of auxiliary working devices. With increasing investment in infrastructure construction and increasingly complex and changing construction environments and working conditions, more and more demands are being placed on loaders, and consequently, the functional requirements for the loader's accessories are also becoming higher.

[0003] Existing loader implements are typically designed for specific working conditions and needs, with each implement only fulfilling one type of task, resulting in relatively limited functionality. However, in practical applications, such as in ranches, forest farms, and landfills, the complex and varied environments, along with differing road widths, necessitate varying requirements for the number of clamps in the loader's clamping implements. Existing clamping implements often employ a one-piece welded design, making it difficult to freely adjust the number of fork teeth and thus unable to meet diverse usage needs. Utility Model Content

[0004] The purpose of this utility model is to provide a clamp body welding component and clamping tool suitable for loaders, so as to solve the technical problem that the existing clamping tools have poor versatility and are difficult to meet different usage needs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A clamp body welding component suitable for a loader includes an upper clamp body frame, a lower clamp body frame, and a drive device; the upper clamp body frame includes two arc-shaped connecting rods, with an upper welding tube between the two connecting rods; the lower clamp body frame includes two fixed rods, with a crossbeam and a lower welding tube respectively provided at the upper and lower ends of the two fixed rods; the upper ends of the two fixed rods are respectively hinged to the two connecting rods, and the upper and lower welding tubes are used to provide welding points for the upper and lower fork teeth, respectively; the drive device is used to drive the upper clamp body frame to rotate relative to each other around the hinge axis.

[0007] Furthermore, the driving device includes two hydraulic cylinders, which are respectively mounted on two fixed rods. The output shafts of the two hydraulic cylinders are respectively connected to the hinged ends of the two connecting rods, and each hydraulic cylinder is provided with several oil pipes.

[0008] Furthermore, a transverse reinforcing rod is fixed on the connecting rod, and multiple longitudinal reinforcing plates are fixed on the transverse reinforcing rod. The multiple longitudinal reinforcing plates are evenly spaced, and the ends of the longitudinal reinforcing plates are fixedly connected to the upper welded pipe.

[0009] Furthermore, the lower clamp frame also includes multiple support plates, with both ends of the support plates fixed to the crossbeam and the lower welded pipe, respectively, and an oil pipe fixing plate fixed in the middle of the support plate, with the oil pipe fixed on the oil pipe fixing plate.

[0010] Furthermore, ribs are provided between the crossbeam and the two fixed rods, between the transverse reinforcing rod and the connecting rod, and between the support rod and the lower welded pipe.

[0011] Furthermore, the circular dimensions of the upper clamp frame and the lower clamp frame are φ560mm±10mm.

[0012] A clamping tool suitable for a loader includes the aforementioned clamp body welded component suitable for a loader, as well as multiple arc-shaped upper fork teeth and multiple straight lower fork teeth. All upper fork teeth are connected as a whole by an upper connecting rod, and all lower fork teeth are connected as a whole by a lower connecting rod. The ends of the upper fork teeth are provided with grooves, and upper welded tubes are inserted into the grooves and fixed to the upper fork teeth by welding. The ends of the lower fork teeth are provided with gaskets, and the lower fork teeth, gaskets, and lower welded tubes are fixed together by welding.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] 1. The clamp body welding component of this utility model, by setting up upper welding pipe and lower welding pipe, can provide free welding points for upper and lower fork teeth. It can freely select an appropriate number of upper and lower fork teeth for combination welding according to actual working conditions and customer needs, which has good versatility, reduces the repetitive design of clamp-type devices, and shortens the manufacturing time of special machines.

[0015] 2. Traditional clamping devices use a single back plate to support the lower clamp frame structure, which requires a large amount of material and additional reinforcing ribs. This utility model combines and welds the oil pipe fixing plate and the support plate together, which not only strengthens the structure but also provides a larger material loading space. While saving raw materials, it has a rounded size of 560mm in diameter. Attached Figure Description
