Description

Technical Field

[0001] The present application belongs to the technical field of gas cylinder transport vehicles, and in particular, relates to a gas cylinder transport vehicle with good stability. Background Art

[0002] Steel cylinders are common containers used in specialty gas production companies and other industrial applications. They are characterized by high pressure, high strength, large mass, high risk, and difficulty in handling.

[0003] The existing Chinese patent with publication number CN112520636B discloses an intelligent cylinder handling device, which includes an AGV, a grabbing and lifting device, an intelligent control module, an automatic cylinder detection device and an anti-static device. The intelligent control module controls the automatic operation of the AGV and the grabbing device; the automatic cylinder detection device is composed of a color sensor, a gas leakage sensor, a weight sensor and an alarm; the anti-static device is composed of an electrostatic ball and a conductive wire.

[0004] The above invention can automatically transport multiple cylinders, has high handling efficiency, automatically identifies gas, automatically detects whether gas leaks, has a high degree of automation, and is relatively safe when transporting cylinders. However, the device grabs the cylinders through the grabbing arm, which cannot be stably grasped, and the cylinders are easy to slip out of the grabbing arm. After the cylinders are placed in the device, they cannot be fixed before transportation, and the stability is poor. Utility Model Content

[0005] The purpose of the present application is to provide a gas cylinder transport vehicle with good stability in order to solve the above-mentioned technical problems. The gas cylinder transport vehicle can stably grab the cylinder and the cylinder can be fixed after being placed in the transport vehicle, so the stability is good.

[0006] The present application provides a gas cylinder transport vehicle with good stability, including a transport vehicle body, wherein the transport vehicle body includes:

[0007] A gripping mechanism, comprising a bracket, an abutment rod, a clamping assembly and a driving assembly;

[0008] A fixing mechanism including a rotating frame;

[0009] Carrier plate;

[0010] Gas cylinders;

[0011] Wherein, the abutment rod is provided with an arc groove, the arc groove cooperates with the bottom of the gas cylinder, the abutment rod is slidably connected to the bracket, and the driving assembly is connected to the bracket.

[0012] In the present technical scheme, a grabbing mechanism and a fixing mechanism are arranged in the transport vehicle body, and a bracket, an abutting rod, a clamping assembly and a driving assembly are arranged in the grabbing mechanism. When the transport vehicle body places the gas cylinder into the vehicle, the driving assembly controls the displacement of the bracket, and then the abutting rod is slid at the bracket, and an arc groove is arranged on the abutting rod, and the arc groove cooperates with the bottom of the gas cylinder to make the abutting rod contact with the bottom of the gas cylinder, so that the grabbing mechanism can stably support the bottom of the gas cylinder and control the clamping assembly to clamp the middle position of the gas cylinder at the same time. At this time, the grabbing mechanism can stably grab the gas cylinder, and then the driving assembly controls the displacement of the bracket to move the gas cylinder to the fixing mechanism on the loading plate. After the gas cylinder is placed on the fixing mechanism, the rotating frame is triggered to rotate. After the rotating frame rotates, the gas cylinder can be fixed on the loading plate, and the staff can stably transport the gas cylinder, thereby improving the stability of the transport vehicle body.

[0013] Furthermore, the grabbing mechanism comprises:

[0014] A limiting rod, which is slidably connected to the bracket;

[0015] Hydraulic cylinder;

[0016] Wherein, the abutment rod and the clamping assembly are connected via a hydraulic cylinder.

[0017] In the present technical scheme, a limit rod and a hydraulic cylinder are arranged on the grasping mechanism, and the limit rod is slidably connected to the bracket. After the clamping assembly clamps the gas cylinder bottle, the staff slides the limit rod. At this time, the limit rod can apply pressure to the gas cylinder in a direction perpendicular to the pressure of the clamping assembly, so as to further fix the gas cylinder, reducing the probability of the gas cylinder falling during the grasping process. The abutment rod and the clamping assembly are connected by the hydraulic cylinder, so that the abutment rod can slide stably to the bottom of the gas cylinder, and after the hydraulic cylinder is extended and retracted, the structure is relatively stable, and the abutment rod and the clamping assembly cooperate to grasp the gas cylinder, which makes the grasping more stable and improves the stability of the transporter body.

[0018] Furthermore, the clamping assembly comprises:

[0019] Motor, including lead screw;

[0020] A clamping block, which cooperates with the screw rod;

[0021] Wherein, the clamping block is provided with a rubber pad.

[0022] In the present technical scheme, a motor and a clamping block with a screw rod are arranged in the clamping assembly, and the clamping block cooperates with the screw rod. After the contact between the abutment rod and the bottom of the gas cylinder, the motor is triggered to rotate, and the motor drives the screw rod to rotate, so that the clamping block is displaced on the screw rod, and the clamping blocks placed at both ends of the bracket approach or move away from each other to facilitate the clamping block to clamp the gas cylinder, and a rubber pad is arranged on the clamping block. The rubber pad increases the friction between the clamping block and the gas cylinder, so that the clamping assembly can stably clamp the gas cylinder, and the material of the rubber pad is relatively soft, which can effectively prevent the outer surface of the gas cylinder from being scratched and worn during clamping, thereby extending the service life of the gas cylinder.

[0023] Furthermore, the driving component comprises:

[0024] A turntable, which is rotatably connected to the loading plate;

[0025] A first electric telescopic rod, a fixed end of which is connected to the turntable;

[0026] The second electric telescopic rod has a fixed end connected to the movable end of the first electric telescopic rod, and a movable end connected to the bracket.

[0027] In the present technical scheme, a turntable, a first electric telescopic rod and a second electric telescopic rod are arranged on the driving assembly, the turntable and the loading plate are rotatably connected, the fixed end of the first electric telescopic rod is connected to the turntable, and the fixed end of the second electric telescopic rod is connected to the movable end of the first electric telescopic rod, and the movable end of the second electric telescopic rod is connected to the bracket. When the staff brings the transport vehicle body to the vicinity of the gas cylinder, they first rotate the turntable to align the abutment rod and the clamping assembly in the grasping mechanism with the gas cylinder, then adjust the first electric telescopic rod to make the clamping assembly contact with the surface of the gas cylinder, and then adjust the second electric telescopic rod to make the clamping assembly correspond to the middle position of the gas cylinder, and finally adjust the hydraulic cylinder to make the abutment rod contact with the bottom of the gas cylinder, thereby ensuring that the grasping mechanism can stably grasp the gas cylinder and is safer to use.

[0028] Furthermore, the fixing mechanism comprises:

[0029] A button including a first contact;

[0030] Torsion spring;

[0031] A snap, including an electromagnet;

[0032] The carrier plate is provided with a second contact and a permanent magnet. When the first contact and the second contact are in contact, the electromagnet is triggered to be energized. After the electromagnet is energized, it is connected to the permanent magnet. The rotating frame and the carrier plate are rotationally connected via a torsion spring.

[0033] In the present technical solution, a button with a first contact and a buckle with an electromagnet are provided on the fixing mechanism, and a second contact and a permanent magnet are provided on the loading plate. The buckle cooperates with the rotating frame. After the gas cylinder is placed on the fixing mechanism, the button is pushed to slide, so that the first contact on the button cooperates with the second contact in the loading plate. After the first contact contacts the second contact, the electromagnet is triggered to be energized. After the electromagnet is energized, it is connected to the permanent magnet, that is, the buckle slides to the permanent magnet, thereby releasing the cooperation between the buckle and the rotating frame. The rotating frame and the loading plate are rotatably connected via a torsion spring. At this time, the rotating frame can rotate via the torsion spring to fix the gas cylinder, so that the transport vehicle body can stably transport the gas cylinder with good stability.

[0034] Furthermore, the transport vehicle body is also provided with a pull rod;

[0035] Wherein, the pull rod is rotatably connected to the transport vehicle body.

[0036] In this technical solution, a pull rod is arranged on the transport vehicle body, and the staff pulls the transport vehicle body through the pull rod, which makes it convenient for the staff to apply pulling force to the transport vehicle body. The pull rod is rotatably connected to the transport vehicle body, which makes it easy for the staff to adjust the pull rod to a position suitable for pulling. The use is convenient and quick.

[0037] The beneficial effects of this application are:

[0038] 1. Make the abutment rod contact the bottom of the gas cylinder, and control the clamping assembly to clamp the middle position of the gas cylinder, so that the grasping mechanism can grasp the gas cylinder stably. Then, the driving assembly is used to control the displacement of the bracket to move the gas cylinder to the fixing mechanism on the carrier. After the gas cylinder is placed on the fixing mechanism, the rotating frame is rotated to fix the gas cylinder on the carrier, so that the staff can transport the gas cylinder stably.

[0039] 2. Make the clamps at both ends of the bracket move closer to or farther away from each other so that the clamps can clamp according to the diameter of the gas cylinder. The rubber pads on the clamps increase the friction between the clamps and the gas cylinder, so that the clamping assembly can stably clamp the gas cylinder. The rubber pads are made of a relatively soft material, which can effectively prevent the outer surface of the gas cylinder from being worn and extend the service life of the gas cylinder.

[0040] 3. After the gas cylinder is placed on the fixing mechanism, push the button to make the first contact on the button contact with the second contact in the loading plate. After the first contact contacts the second contact, the electromagnet is triggered to be energized. After the electromagnet is energized, it is connected with the permanent magnet, that is, the buckle slides to release the cooperation between the buckle and the rotating frame. After that, the rotating frame can be rotated by the torsion spring to fix the gas cylinder, and the stability is better. BRIEF DESCRIPTION OF THE DRAWINGS
