Description

Technical Field

[0001] The utility model relates to the technical field of steel pipes, in particular to a fast-fixing steel pipe clamp. Background Art

[0002] Steel pipes are widely used in the fields of construction and machinery. As an economical steel material, steel pipes can be used to transport fluids and powdered substances, and can also be used as parts for manufacturing machinery. During the use of steel pipes, they often need to be processed to obtain the required size and shape for use. Generally, steel pipes need to be cut, welded, and externally polished and rust-removed.

[0003] When the existing fixing device for steel pipe processing clamps the steel pipe, it is usually necessary for the relevant personnel to tighten the threads to apply pressure to the surface of the steel pipe to be processed to clamp it, and then fix the clamping device before the steel pipe can be processed. Such a clamp is cumbersome to operate and the clamping takes a long time; thereby increasing the complexity of the labor of the relevant personnel and also delaying the processing efficiency of the steel pipe.

[0004] Therefore, in order to solve the above technical problems, the utility model provides a steel pipe clamp that can be quickly fixed to solve the above problems. Utility Model Content

[0007] Furthermore, pressure sensors are installed on the inner sides of the left clamping claw and the right clamping claw of the upper clamping part, and the pressure sensors are electrically connected to the horizontal moving mechanism.

[0008] Furthermore, a control center is provided on the upper surface of the upper clamping part, and the control center is electrically connected to the horizontal moving mechanism, the pressure sensor and the lifting rod.

[0009] Furthermore, the length of the lifting rod when it reaches the maximum stroke is smaller than the length of the support rod.

[0010] Furthermore, contact sensors are installed on the inner sides of the left clamping claw and the right clamping claw of the lower clamping part; and the contact sensors are electrically connected to the control hub.

[0011] Furthermore, the right clamping claw of the upper clamping part and the right clamping claw of the lower clamping part are located on the same line.

[0012] The beneficial effects of the utility model are:

[0013] The utility model adopts a hydraulic mechanism to continuously apply pressure so that the clamp can automatically clamp steel pipes of different diameters. When in use, only the switch button needs to be pressed and the clamping mechanism will start to start until the clamp is clamped. The operation is simple and there is no additional operation. It not only reduces the operating steps of relevant personnel but also shortens the time for clamping the steel pipe, greatly improving the processing efficiency.

[0025] A control center 10 is disposed on the upper surface of the upper clamping portion 1 , and the control center 10 is electrically connected to the horizontal moving mechanism 4 , the pressure sensor 6 and the lifting rod 9 .

[0026] The length of the lifting rod 9 when it reaches the maximum stroke is smaller than the length of the supporting rod 8 .

[0027] Contact sensors 11 are installed on the inner sides of the left clamping claw 5 and the right clamping claw 7 of the lower clamping part 3 ; the contact sensors 11 are electrically connected to the control center 11 .

[0028] The right clamping claw 7 of the upper clamping part 1 and the right clamping claw 7 of the lower clamping part 3 are located on the same line.

[0029] Example 2

[0030] The clamp is hydraulically operated, so a through hole is provided on the outside. A connecting pipe passes through the through hole to connect the lifting rod 9, the horizontal displacement mechanism 4 and the hydraulic press, and a solenoid valve is provided on the connecting pipe. The solenoid valve is directly electrically connected to the control center; the control center can control the opening and closing of the solenoid valve on the connecting pipe to realize the control of the overall hydraulic device.

[0031] Example 3

[0032] Working principle:

[0033] S1. Before the device is put into operation, press the switch button, the clamp is powered on and started, the control center 10 is started, the control solenoid valve is opened, and the hydraulic system can operate normally; the control center 10 operates the horizontal moving mechanism 4 of the clamp to drive the left clamping claw 5 to move to the minimum stroke, and operates the lifting rod 9 to move vertically to the farthest stroke position, completing the initial preparation.

[0034] S2. After the preparation work is completed, the steel pipe can be placed into the clamp from one side of the clamp, and after the outer side of the steel pipe contacts the right clamping claw 7 of the lower clamping part 3, the first clamping button is pressed to start the horizontal moving mechanism 4 of the lower clamping part 3, so that the contact sensor on the inner wall of the left clamping claw 5 of the lower clamping part 3 fits the outer side of the steel pipe. At this time, after the control panel receives the signal of the contact sensor 11 on the inner wall of the left clamping claw 5 of the lower clamping part 3, the horizontal moving mechanism 4 of the lower clamping part 3 is automatically closed to fix the relative position to ensure the longitudinal pressure, and at the same time, the lifting rod 9 is started to move, driving the upper clamping part 1 to move downward at a uniform speed. When the right clamping claw 7 of the upper clamping part 1 contacts the outer side of the steel pipe, the pressure sensor is compressed. After the force is applied, the signal is fed back to the control panel, and the control panel automatically controls the horizontal moving mechanism 4 of the upper clamping part 1 to move, so that the pressure sensor on the inner wall of the left clamping claw 5 of the upper clamping part 1 fits the outer side of the steel pipe and continues to pressurize. When the pressure monitored by the pressure sensor on the inner wall of the left clamping claw 5 reaches a preset threshold, the control panel automatically controls the horizontal moving mechanism 4 of the upper clamping part 1 to close, fix the relative position, ensure the lateral pressure, and complete the clamping of the steel pipe. At this time, since the height of the minimum stroke of the lifting rod 9 is higher than the highest point of the right clamping claw 7 of the lower clamping part, when the upper clamping part 1 moves downward, the right clamping claw 7 of the upper clamping part 1 will not collide with the right clamping claw 7 of the lower clamping part 3.

[0035] S3. When the steel pipe processing is completed, operate the control center 10 and the clamp starts to reset; use the control center 10 to operate the clamp to start resetting, the horizontal moving mechanism 4 located at the upper clamping part 1 and the lower clamping part 3 is started, driving the left clamping claw 5 to move horizontally to the initial position, and then the lifting rod 9 moves vertically to its farthest stroke position, all devices move to the initial position, press the switch button, the control center controls the solenoid valve to close, and then the clamp automatically cuts off the power.

[0036] Existing steel pipe clamps usually use threaded tightening to fix, which has great limitations; manual tightening takes time, and the tightening pressure is also related to the habits of different personnel, so there will be deviations in the final tightening effect, and the processing efficiency will also be greatly affected. However, the utility model uses hydraulic pressure to give pressure, which greatly speeds up the tightening speed, and all mechanisms are controlled by one button, which not only avoids the influence of factors such as personnel experience during operation, but also greatly reduces the clamping time, so that the efficiency of steel pipe processing can be accelerated and the burden on staff can be reduced.
