A type of lifting clamp for dump truck boxes

Abstract

This utility model provides a lifting clamp for dump truck bodies, belonging to the field of lifting clamp technology. The lifting clamp includes a lifting beam, with dampers fixedly installed around the top surface of the beam. A shock-absorbing spring is sleeved on the surface of each damper. A lifting assembly is fixedly installed on the top of the dampers and shock-absorbing springs. An adjusting assembly is fixedly installed at one end of the lifting beam, and moving rods are threadedly connected to both sides of the adjusting assembly. This utility model uses a servo motor to drive a bidirectional lead screw to rotate, causing two sets of moving rods to move in opposite directions. This adjusts the length of the extension rod, allowing it to slide inside the moving rod. Tightening the adjusting stud secures the rod, and then tightening the threaded lead screw moves the B clamping tooth, which, in conjunction with the A clamping tooth, clamps and fixes the dump truck body wall. This achieves the effect of adjusting the overall length and width of the clamp, facilitating stable clamping and fixing of dump truck bodies of different sizes.

Description

Technical Field

[0001] This application relates to the field of lifting clamp technology, and in particular to a lifting clamp for a dump truck box. Background Technology

[0002] Off-highway (mining) dump trucks are heavy-duty dump trucks used in open-pit mines for rock and soil stripping and ore transportation. They are characterized by short transport distances and heavy loads, and are typically loaded using large electric or hydraulic shovels, shuttling between mining and unloading points. During the hoisting process of the dump truck body, clamps are used to secure it.

[0003] However, traditional dump truck box lifting clamps are not convenient for adjusting the length and width of the clamps, making them unsuitable for adapting to different sizes of truck boxes. Moreover, during the lifting process, the truck box sways significantly, increasing the load on the load and increasing the risk of accidents. Utility Model Content

[0004] This application provides a lifting clamp for dump truck bodies to solve the problems of inconvenience in adjusting the length and width of the clamp and large swaying of the truck body during the lifting process.

[0005] This application provides a lifting clamp for a dump truck body, including a lifting beam. Dampers are fixedly installed around the top surface of the lifting beam. A shock-absorbing spring is sleeved on the surface of the damper. A lifting assembly is fixedly installed on the top of the damper and the shock-absorbing spring. An adjusting assembly is fixedly installed at one end of the lifting beam. Moving rods are threadedly connected to both sides of the surface of the adjusting assembly. An extension rod is slidably installed inside the moving rod. A connecting rod is fixedly installed at one end of the extension rod. A clamping rod is fixedly installed on the bottom surface of the connecting rod. A fastening assembly is rotatably installed at one end of the clamping rod. A clamping tooth A is fixedly installed on one side of the bottom surface of the clamping rod.

[0006] Preferably, the lifting assembly includes a top plate and a lifting ring. The top plate is fixedly disposed on the top of the damper and the shock-absorbing spring, and the lifting ring is fixedly disposed on the top surface of the top plate. The lifting ring facilitates the lifting of the carriage.

[0007] Preferably, the adjustment assembly includes a servo motor and a bidirectional lead screw. The servo motor is fixedly mounted on one end of the hoisting beam, and the bidirectional lead screw is fixedly mounted on the output end of the servo motor. The servo motor is used to drive the bidirectional lead screw to rotate.

[0008] Preferably, the fastening assembly includes a threaded screw and a B-tooth clamp, the threaded screw being rotatably disposed at one end of the clamping rod, and the B-tooth clamp being threadedly connected to the surface of the threaded screw, the threaded screw being used to drive the B-tooth clamp to move.

[0009] Preferably, the top surface of the hoisting beam is provided with a limiting groove, and the tops of both sets of moving rods are slidably disposed inside the limiting groove, which facilitates the sliding of the moving rods.

[0010] Preferably, a threaded hole is provided on one side of the surface of the movable rod, and an adjusting stud is passed through the internal thread of the threaded hole. Several adjusting studs are provided on the surface of the extension rod along the axial direction, so that the extension rod can be used to adjust the overall length of the movable rod and the extension rod.

[0011] Preferably, the top surface of the clamping rod is provided with a sliding groove, and the top of the B clamping tooth is slidably disposed inside the sliding groove, so that the sliding groove facilitates the sliding of the B clamping tooth. Beneficial effects

[0012] Considering the inconvenience of adjusting the length and width of the clamp and the large sway of the truck body during hoisting, the servo motor drives the bidirectional lead screw to rotate, causing the two sets of moving rods to move in opposite directions. This allows the length of the extension rod to be adjusted so that it slides inside the moving rod. The adjusting stud is then tightened to fix it, and the threaded screw is tightened to drive the B clamping tooth to move. Together with the A clamping tooth, the B clamping tooth clamps and fixes the dump truck body wall, thus achieving the effect of adjusting the overall length and width of the clamp, which is convenient for stable clamping and fixing dump truck bodies of different sizes.

[0013] During the hoisting process, when the dump truck body sways, the damping spring deforms to absorb the swaying force, and the damper consumes the stored energy of the damping spring, thus achieving the effect of buffering and reducing vibration of the hoisting beam, reducing the swaying amplitude, avoiding increased load, and improving the safety of hoisting.
