Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical gripping technology, and in particular to a gripping device for the conveying pipe of a vehicle carrying mixed emulsion explosives. Background Technology
[0002] At the site where mixed emulsion explosives are being loaded, rubber conveying hoses of different specifications are typically used to transport the mixed emulsion explosives from the vehicle-mounted equipment into the blast hole, completing the loading according to the blasting design requirements. The rubber conveying hoses become crucial equipment for transporting the mixed emulsion explosives, affecting loading efficiency and safety. However, due to the unique ground environment at the blasting site, which is almost entirely composed of crushed ore from the previous blast, leveled by a loader to facilitate the movement of the mixed explosives loading vehicle, this process is challenging.
[0003] The delivery pipes are typically 30-40 meters long and 25mm, 30mm, 40mm, 45mm, 50mm, and 60mm in diameter. If there is explosive material inside, the weight is considerable. Moving the pipes between blast holes relies on on-site personnel manually gripping the rubber hoses. Over time, this has led to personnel dragging the pipes across the crushed ore surface, causing severe wear and tear, reducing the pipes' lifespan, increasing the workload for on-site personnel, and increasing the risk of falls and injuries if they lose their footing. Similar accidents have already occurred. This invention addresses the problems of inconvenience, safety hazards, and high labor intensity associated with on-site personnel directly gripping the pipes. Summary of the Invention
[0004] To address the aforementioned defects or deficiencies, the purpose of this utility model is to provide a gripping device for the conveying pipe of a vehicle used for mixing emulsion explosives. This device moves the rubber pipe safely and conveniently by controlling the gripper and handle.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A gripping device for a delivery pipe of a vehicle used for mixing emulsion explosives includes: a telescopic rod, with a detachable movable gripper installed at the end of the telescopic rod, and a control structure for opening the movable gripper installed on the movable gripper.
[0007] The movable gripper includes: a connecting rod, which is installed on the top of the telescopic rod. A fixed claw is installed at the end of the connecting rod. The fixed claw is connected to a movable claw via a movable pin. A spring is installed on the movable claw.
[0008] One end of the spring is mounted on the connecting rod via a first spring bolt, and the other end is mounted on the movable jaw via a second spring bolt.
[0009] The connecting rod is fixedly connected to the telescopic rod by a connecting pin.
[0010] The telescopic rod includes a handle on which a telescopic extension rod is mounted.
[0011] The handle is provided with a handle at the end of the handle.
[0012] The closing diameter of the moving gripper can be changed according to the diameter of the pipe being gripped.
[0013] The closing diameter of the moving gripper is 25mm, 30mm, 40mm, 45mm, 50mm, or 60mm.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This utility model provides a gripping device for the conveying pipe of a mixed emulsion explosive vehicle. It is equipped with a replaceable movable gripper. In practical applications, the corresponding gripper can be selected according to the diameter of the conveying pipe to grip the pipe, replacing the manual gripping of the rubber tube. The person moves the rubber tube by controlling the gripper and handle, which is safe and convenient, and avoids wear and tear on the pipe. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.
[0020] like Figure 1 As shown, this utility model provides a gripping device for the conveying pipe of a vehicle carrying mixed emulsion explosives, including: a telescopic rod 1, a detachable movable gripper 2 installed at the end of the telescopic rod 1, and a control structure for opening the movable gripper 2 installed on the movable gripper 2.
[0021] Specifically, the movable gripper 2 includes a connecting rod 2-6, which is mounted on the top of the telescopic rod 1. A fixed claw 2-1 is mounted at the end of the connecting rod 2-6. The fixed claw 2-1 is connected to a movable claw 2-2 via a movable pin. A spring 2-3 is mounted on the movable claw 2-2. One end of the spring 2-3 is mounted on the connecting rod 2-6 via a first spring bolt 2-5, and the other end is mounted on the movable claw 2-2 via a second spring bolt 2-4. This spring 2-3 can generate a pushing force on the movable claw 2-2, creating a gripping pressure between the two claws. When the conveying pipe is gripped between the claws, it can exert a gripping force on the conveying pipe. For example, the connecting rod 2-6 is fixedly connected to the telescopic rod 1 via a connecting pin 1-3. Preferably, a silicone layer is provided on the inner wall of the fixed claw 2-1 and the movable claw 2-2 to increase friction and protect the pipe.
[0022] In this utility model, the structure of the telescopic rod 1 can be set according to the length of the telescopic extension. For example, the telescopic rod 1 includes: a handle, on which a telescopic extension rod 1-2 is installed, and a handle 1-1 is provided at the end of the handle.
[0023] like Figure 2 As shown in the present invention, the outer back wall of the movable claw 2-2 is provided with a pull rope 2-7. The pull rope 2-7 passes around the connecting pin 1-3 and extends to the handle 1-1. It is positioned by a movable component. The pull rope 2-7 is centered on the first spring bolt 2-5 and rotates around the second spring bolt 2-4 below. Under the tension of the pull rope, the movable claw 2-2 opens and releases the pipe. When it needs to be closed, it is closed by the rebound force of the spring 2-3.
[0024] Preferably, in this invention, in order to clamp pipes of different specifications, the closing diameter of the movable gripper 2 can be changed according to the diameter of the pipe being gripped. The closing diameter of the movable gripper 2 is 25mm, 30mm, 40mm, 45mm, 50mm, or 60mm.
[0025] In addition, this utility model is equipped with a gripper storage box 3, mainly for storing grippers of different sizes. When the entire device is not in use, it consists of two parts: a telescopic rod 1 and a gripper storage box 3 for the movable gripper 2.
[0026] The operation is as follows: Open the storage box 3, take out the movable gripper 2 that matches the diameter of the rubber tube to be gripped on site, and connect it to the gripper's connecting pin through the handle connecting pin 1-3. Before gripping, the operator opens the movable claw 2-2 by pulling the rope 2-7. At this time, the spring 2-3 connected to the movable claw 2-2 is in a compressed state. Insert the fixed claw 2-1 into the lower half of the rubber tube from the bottom, and then release the rope 2-7. Under the rebound force of the spring 2-3, the movable claw 2-2 closes, completing the gripping of the rubber tube. The number of grippers used depends on the number of people moving it. Then, several people simultaneously use the handle to grip the rubber tube and lift it off the ground to move it to the next blast hole. Because the movable connecting pin 1-3 is used in the middle, there is room for movement when moving the rubber tube, so that the whole device is not fixed relative to the rubber tube, which would cause personnel to be twisted and injured by hard dragging.
[0027] It will be apparent to those skilled in the art that the above specific examples are merely preferred embodiments of this utility model. Therefore, any improvements or modifications that those skilled in the art may make to certain parts of this utility model still embody the principles of this utility model and achieve its purpose, and all fall within the scope of protection of this utility model.
