Vehicle-mounted gripping mechanism

Abstract

The invention relates to vehicle-mounted gripping mechanism. A large arm first hinge hole and a large arm second hinge hole are formed in the upper end of a large arm; a large arm oil cylinder hinge hole is formed in the telescoping end of a large arm oil cylinder; a variable amplitude component first hinge hole and a variable amplitude component second hinge hole are formed in one end of a variable amplitude component; a first connecting rod is provided with a first connecting rod first hinge hole and a first connecting rod second hinge hole; a second connecting rod is provided with a secondconnecting rod first hinge hole and a second connecting rod second hinge hole; the large arm first hinge hole is in pin connection with the first connecting rod first hinge hole; the large arm secondhinge hole is in pin connection with the variable amplitude component first hinge hole; the variable amplitude component second hinge hole is in pin connection with the second connecting rod first hinge hole; and the large arm oil cylinder hinge hole and the first connecting rod second hinge hole are in pin connection with the second connecting rod second hinge hole. The vehicle-mounted gripping mechanism has the advantages that the self-unloading operating efficiency is improved, the object gripping safety coefficient is raised, the driving safety performance is improved, and the service lifeof a gripping apparatus is prolonged.

Description

technical field [0001] The invention relates to a dump truck with a grab, in particular to a grab mechanism on a dump truck with a grab. Background technique [0002] The loading and unloading of the goods on the traditional transport vehicle are all carried by manpower, or realized by an external grabbing mechanism. Manual handling will use a lot of manpower, and the efficiency is low, and there are potential safety hazards; the external grabbing mechanism needs an external grabbing mechanism for loading, and an external grabbing mechanism for unloading. , especially for outdoor places, it is difficult for the grabbing mechanism to reach the destination, and the grabbing of the external grabbing mechanism is only suitable for fixed-point grabbing, and the environmental adaptability is poor. The Chinese patent No. 201620796719.5 discloses a transport vehicle with a vehicle-mounted grasping mechanism at the rear, which can solve the above-mentioned problems. [0003] Howeve...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the vehicle-mounted grasping mechanism is set at the rear section of the transport vehicle, the transport vehicle with this structural layout does not have the self-unloading function, so it can be considered to set the vehicle-mounted grasping mechanism at the middle section of the transport vehicle, so that the rear The compartment can realize self-unloading function, see Figure 1-Figure 4 However, the arm of the traditional vehicle-mounted gripping mechanism is a straight arm. Due to its large size, it still occupies a large space in the non-working state. Therefore, the arm of the vehicle-mounted gripping mechanism is located directly above the compartment when the vehicle is running. Yes, when the vehicle arrives at the destination and needs to be unloaded, it is necessary to lift the arm of the vehicle grabbing mechanism first, otherwise the arm of the arm of the vehicle grabbing mechanism will affect the self-unloading function of the car. The lowering of the arm of the vehicle grabbing mechanism makes the vehicle self-unloading process more cumbersome, so it is considered to develop a vehicle-mounted grabbing mechanism in the form of a folding arm facing the side

[0005] 2. Since the traditional transport vehicle with a vehicle-mounted grasping mechanism grabs materials, the two support legs under the grasping mechanism are used to support the vehicle body. When the vehicle is grasping the materials on the left and right sides of the carriage, If the material is overweight, it may cause the vehicle to roll over. If the arm of the traditional vehicle is a straight arm, the winch is used for telescopic and lifting. The range finder is installed on the steel rope of the winch, but the arm is folded The winch cannot be installed on the vehicle-mounted grab mechanism, so the rangefinder cannot be installed, so the anti-rollover function cannot be realized;

[0006] 3. The arm of the traditional vehicle-mounted grabbing mechanism only uses an automatic anti-off device, which is an inertial self-locking device. In general, it is used in conjunction with the interlocking of the oil cylinder, but in emergencies, such as sharp turns, sideways Turn over, when hit, it will be opened automatically by the impact, and cause secondary damage;

[0007] 4. The gripper of the traditional car-mounted gripping mechanism has only two petals, four petals, five petals, and six petals. difficult to meet
