Description

Technical Field

[0001] This utility model relates to a pipe clamping device, and more particularly to a tunnel escape pipe clamping device. Background Art

[0002] Traditional tunnel escape pipes typically use 9000*820*10mm steel pipes, 3000*800*30mm fiberglass spiral wound pipes, or 3000*800*30mm polyethylene pipes, connected by methods such as sleeve welding, flange connections, chain connections, or clamp connections. The minimum weight of a single section in this type of escape pipe exceeds 200KG. Due to the limited working space inside the tunnel, the transportation and installation of tunnel escape pipes are almost entirely done manually. The escape pipes are quite heavy, making manual handling and installation extremely inefficient. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a pipe clamping device to improve the efficiency of pipe handling.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A pipe clamping device includes a clamping bracket, with hydraulic rods fixedly connected to both sides of the top of the clamping bracket. One end of each hydraulic rod passes through the clamping bracket and extends to the outside of the clamping bracket. Pins are rotatably connected to both sides of the bottom of the clamping bracket. A gripper is connected to each pin, and a fork is rotatably connected to the gripper. One end of the fork is rotatably connected to one end of the hydraulic rod.

[0006] As a preferred embodiment, a connecting rod is provided between the grippers. The connecting rod connects the two grippers into a whole, ensuring the synchronization of the grippers.

[0007] As a preferred embodiment, the gripper is provided with anti-slip teeth.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This invention is simple to operate, safe and reliable, and can achieve fast and safe clamping of pipelines, significantly improving efficiency. Related samples have been completed and are currently in use. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model;

[0011] Figure 2 This is a top view of the present invention;

[0012] Among them, 1 is a hydraulic rod, 2 is a clamping bracket, 3 is a shift fork, 4 is a gripper, 5 is a connecting rod, 6 is a rotary reducer, and 7 is a solenoid valve. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings.

[0014] Example:

[0015] like Figure 1 As shown, a pipe clamping device includes a clamping bracket 2. Hydraulic rods 1 are fixedly connected to both sides of the top of the clamping bracket 2. One end of each hydraulic rod 1 passes through the clamping bracket 2 and extends to the outside of the clamping bracket 2. Pins 5 are rotatably connected to both sides of the bottom of the clamping bracket 2. Handles 4 are connected to the pins 5. Forks 3 are rotatably connected to the outside of each hand. One end of the fork 3 is rotatably connected to one end of the hydraulic rod 1. A connecting rod 5 connects the two handles 4 into a single unit, ensuring the synchronization of the handles 4. Each handle 4 is equipped with anti-slip teeth.

[0016] When the hydraulic rod 1 extends under the push of hydraulic oil, it pushes the fork 3 to move to the left at the connection end with the hydraulic rod 1. The fork 3 pushes the gripper 4, causing the gripper 4 to release. When the hydraulic rod 1 returns to its original position, it pulls the fork 3 to move to the right. The fork 3 pulls the gripper 4, causing the gripper 4 to clamp the workpiece.

[0017] The above embodiments of this utility model are merely illustrative examples and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations and modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
