Description

Technical Field

[0001] This utility model relates to the field of power clamp technology, and in particular to a power clamp equipped with a high and low position operating device. Background Technology

[0002] In the oil drilling industry, drill pipe power tongs are commonly installed at the wellhead to improve mechanization, reduce the workload of wellhead operators, and ensure their personal safety.

[0003] Currently, when using drill pipe power tongs, in situations involving heavy drill pipes, hydraulic tilting chucks, external pneumatic chucks, or three-piece drill pipe slips, the tongs need to be lifted to a certain height for operation. In such cases, it is very inconvenient for operators to operate the drill pipe power tongs at the original height, which increases the limitations of the drill pipe power tongs' use. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to propose a power clamp equipped with a high and low position operating device to solve the problem of increased limitations in the use of power clamps.

[0005] To achieve the above objectives, this utility model provides a power clamp equipped with a high / low position operating device, comprising a power clamp body, an operating device on the power clamp body, a bracket connected to the power clamp body, a sliding groove on one lower end of the bracket, an inner rod slidably connected in the sliding groove, a valve group connected to the lower end of the inner rod, a control switch of the power clamp body integrated on the valve group, a control box electrically connected to the valve group on the outside of the bracket, and a cylinder for controlling the raising and lowering of the inner rod on the outside of the bracket, the telescopic end of the cylinder being connected to the outer wall of the inner rod, and the cylinder being electrically connected to the control box.

[0006] Optionally, a rotating component is provided between the bracket and the valve assembly. The rotating component includes a rotating plate fixedly connected to the valve assembly. The rotating plate and the bracket are rotatably connected via a rotating shaft. The rotating plate is provided with a plurality of eccentric limiting holes. A limiting pin is fitted on the eccentric limiting holes. The bracket is provided with a mating hole that mates with the limiting pin.

[0007] Optionally, a rotary motor is provided on the rotary plate, and the output end of the rotary motor is connected to the rotary shaft for transmission.

[0008] Optionally, the inner rod is provided with a track that is slidably engaged with the slide groove.

[0009] Optionally, the bracket is fixedly connected to the power clamp body.

[0010] Optionally, a reinforcing rib is provided on one side of the bracket, and the power clamp body is connected to the side wall of the bracket through the reinforcing rib.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a power clamp equipped with a high / low position operating device. The operator can send a control signal to the valve assembly by triggering the control box, thereby driving the cylinder to start. When the valve assembly needs to be adjusted to a high position, the control box controls the cylinder to extend, causing the inner rod of the bracket to extend and simultaneously lift the valve assembly upwards. When switching to a low position, the control box controls the cylinder to retract, pulling the inner rod of the bracket back, causing the valve assembly to move downwards. The entire adjustment process requires no manual handling or prying; the high / low position switching of the valve assembly can be achieved solely through the control box. This not only makes operation convenient and quick but also effectively reduces the labor intensity of the operator and lessens the limitations of the power clamp itself. Attached Figure Description

[0020] like Figures 1 to 4 As shown, a power clamp equipped with a high / low position operating device includes a power clamp body 6. An operating device is provided on the power clamp body 6. The operating device includes a bracket 1 connected to the power clamp body 6. A sliding groove is opened at the lower end of one side of the bracket 1. An inner rod 5 is slidably connected in the sliding groove. A valve group 3 is connected to the lower end of the inner rod 5. The control switch of the power clamp body 6 is integrated on the valve group 3. A control box 4 electrically connected to the valve group 3 is provided on the outside of the bracket 1. A cylinder 2 for controlling the raising and lowering of the inner rod 5 is provided on the outside of the bracket 1. The cylinder 2 is electrically connected to the control box 4. The base of the cylinder 2 is connected to the outside of the bracket 1. The telescopic end of the cylinder 2 is connected to the outer wall of the inner rod 5.

[0021] The bracket 1 adopts a flexible telescopic rod structure, including an inner rod 5 that can be raised and lowered. One end of the bracket 1 is stably connected to the power clamp body 6, providing basic support for the entire high and low position operation device. At the same time, the extension and retraction state of the inner rod 5 on the bracket 1 is directly controlled by the cylinder 2. The overall length of the bracket 1 can be precisely adjusted by the driving force of the cylinder 2, thereby laying the structural foundation for the high and low position switching of the subsequent air valve group 3.

[0022] Cylinder 2 serves as the core of the device's power output. One end is connected to the fixed part of the bracket 1, while the other end is linked to the valve group 3 through the inner rod 5. Its operating state directly determines the position change of the valve group 3, making it a key actuator for driving the operating device to complete high and low position adjustments.

[0023] The air valve group 3 is the integrated carrier of all control switches of the power clamp body 6. The core operation functions of the power clamp body 6, such as starting and stopping, speed adjustment, and clamping force control, are all realized through the corresponding switches on the air valve group 3, which greatly simplifies the operation process and avoids the cumbersome operation problems caused by traditional distributed switches.

[0024] Operators can send control signals to the valve assembly 3 by triggering the control box 4 (e.g., by pressing a button or toggling a switch), which in turn drives the cylinder 2 to start. When the valve assembly 3 needs to be adjusted to a high position, the control box 4 controls the cylinder 2 to extend, causing the inner rod 5 of the bracket 1 to extend and simultaneously lift the valve assembly 3 upwards. When switching to a low position, the control box 4 controls the cylinder 2 to retract, pulling the inner rod 5 of the bracket 1 back, causing the valve assembly 3 to move downwards. The entire adjustment process does not require manual handling or prying; the valve assembly 3 can be quickly switched between high and low positions simply through the control box 4. This not only makes operation convenient and quick, effectively reducing the labor intensity of operators and the limitations of the power clamp body 6, but also has advantages such as simple structural design, reliable component connections, and low failure rate. It can stably adapt to the long-term use needs of the power clamp in complex working conditions such as oilfield wellheads and pipeline construction.

[0025] A rotating component is provided between the support 1 and the valve assembly 3. The rotating component includes a rotating plate 8 fixedly connected to the valve assembly 3. The rotating plate 8 and the support 1 are rotatably connected via a rotating shaft 7. The rotating plate 8 is provided with multiple eccentric limiting holes 9, and limiting pins 10 are fitted onto the eccentric limiting holes 9. The support 1 is provided with mating holes that mate with the limiting pins 10, further improving operational flexibility. The valve assembly 3 is not directly fixed to the inner rod 5 of the support 1, but is connected to the inner rod 5 of the support 1 through a freely rotatable rotating plate 8. The operator can fine-tune the angle and lateral position of the valve assembly 3 by using the rotating plate 8 according to their own standing position, the size of the working space, and other actual conditions, ensuring comfortable operating posture and precise movements. When it is necessary to adjust the tilt angle of the valve assembly 3, the tilt angle of the valve assembly 3 is adjusted. After adjusting the tilt angle of the valve assembly 3, the limiting pins 10 are inserted into the mating holes and the eccentric limiting holes 9 that mate with the mating holes, meeting the convenient operation needs of operators in different working scenarios.

[0026] A rotary motor is installed on the rotating plate 8. The output end of the rotary motor is connected to the rotating shaft 7. The rotary motor is electrically connected to the control box 4. When it is necessary to adjust the tilt angle of the air valve group 3, the rotary motor starts and drives the rotating shaft 7 to rotate, which facilitates the adjustment of the tilt angle of the air valve group 3 and meets the convenient operation needs of operators in different working scenarios.

[0027] The inner rod 5 is provided with a track that slides in conjunction with the slide groove to prevent the inner rod 5 from deflecting during the lifting and lowering process.

[0028] The bracket 1 can be fixedly connected to the power clamp body 6 by screws.

[0029] A reinforcing rib is provided on one side of the bracket 1 at an angle. The reinforcing rib connects the power clamp body 6 to the side wall of the bracket 1, which facilitates the reinforcement of the connection between the bracket 1 and the power clamp body 6.
