This fixing method requires manual disassembly and installation, and can only fix one type of tubular product according to the size of the clamp, which has certain limitations. Content of the Utility Model

A hydraulic cylinder is detachably installed at each corner of the inner assembly plate of the housing, and the piston ends of the four hydraulic cylinders all penetrate through the housing and extend into the insertion hole and are connected with a clamping block. The four hydraulic cylinders are designed in a diagonal pair. An infrared sensor is embedded and installed on the top surface of the housing inside the insertion hole. The top surface of the housing is detachably connected with a housing cover, and a controller is detachably installed in the middle of the bottom surface of the housing cover. The controller is electrically connected with the infrared sensor and the four hydraulic cylinders.

[0006] Preferably, the housing is of a rectangular structure. Two assembly plates are welded on the side of the housing away from the housing cover, and a plurality of holes are formed on the surface of the assembly plates.

[0007] Preferably, the clamping block is of an arc structure.

[0008] Preferably, a pressure sensor is embedded and installed in the middle of each clamping block, and one side of the pressure sensor is flush with the inner arc surface of the clamping block. The pressure sensor is electrically connected with one of the corresponding connected hydraulic cylinders.

[0009] Preferably, the four hydraulic cylinders are respectively arranged at the end corners of the housing, the insertion hole is arranged at the center of the housing, and the piston ends of the four hydraulic cylinders all point to the center of the insertion hole so that the four clamping blocks are coaxially designed with the insertion hole evenly.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] This utility model uses four hydraulic cylinders and clamping blocks arranged at the piston ends of the hydraulic cylinders to clamp the tubular object in the jack. At the same time, it is equipped with an infrared sensor and a controller to detect the tubular object. When a tubular object is inserted into the jack, the hydraulic cylinders are automatically opened for clamping and fixing, greatly improving the convenience of the fixing device. At the same time, four clamping blocks are set to move synchronously towards the midline of the tubular object to clamp and fix the four sides of the tubular object, enabling the clamping and fixing of tubular objects of different sizes and greatly reducing the limitations of the fixing device.

[0015] The following elaborates on the preferred embodiments of this utility model in conjunction with the drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby making the protection scope of this utility model more clearly defined.

[0016] This utility model provides a locking and fixing tooling, as Figure 1-2 shown, which includes a housing 1 and a jack 2 arranged in the middle of the housing 1. A hydraulic cylinder 5 can be detachably installed at each corner of the internal mounting plate 4 of the housing 1, and the piston ends of the four hydraulic cylinders 5 all penetrate through the housing 1 and extend into the jack 2 and are connected with a clamping block 6. The four hydraulic cylinders 5 are designed in a diagonal pair. An infrared sensor 7 is embedded and installed on the top surface of the housing 1 inside the jack 2. The top surface of the housing 1 is detachably connected with a housing cover 3, and a controller 8 is detachably installed in the middle of the bottom surface of the housing cover 3. The controller 8 is electrically connected with the infrared sensor 7 and the four hydraulic cylinders 5.

[0017] Four hydraulic cylinders 5 and clamping blocks 6 arranged at the piston ends of the hydraulic cylinders 5 are used to clamp the tubular object in the jack 2. At the same time, the infrared sensor 7 and the controller 8 are used to detect the tubular object. When a tubular object is inserted into the jack 2, the hydraulic cylinders 5 are automatically opened for clamping and fixing, greatly improving the convenience of the fixing device. At the same time, four clamping blocks 6 are set to move synchronously towards the midline of the tubular object to clamp and fix the four sides of the tubular object, enabling the clamping and fixing of tubular objects of different sizes and greatly reducing the limitations of the fixing device.

[0018] The housing 1 is of a rectangular structure. On one side edge of the housing 1 away from the housing cover 3, two mounting plates 4 are welded, and a plurality of holes are provided on the surface of the mounting plates 4. Four hydraulic cylinders 5 are respectively placed at the end corners of the housing 1. The jack 2 is arranged at the center of the housing 1, and the piston ends of the four hydraulic cylinders 5 all point to the center of the circle of the jack 2, so that the four clamping blocks 6 are coaxially designed with the jack 2. The device can be fixed to the drilling equipment by using the provided mounting plates 4. The jack 2 is of a circular structure and is fixed in cooperation with the clamping blocks 6 around the jack 2. The direction or position of the housing 1 can be installed arbitrarily. The housing 1 can be installed vertically or horizontally, which does not affect the use of the device and greatly improves the flexibility of the device.

[0019] The clamping block 6 is of an arc structure, which is beneficial to increasing the contact area between the clamping block 6 and the side surface of the tubular object, thereby improving the clamping and fixing effect.

[0020] In the middle of each clamping block 6, a pressure sensor 9 is embedded and installed, and one side of the pressure sensor 9 is flush with the inner arc surface of the clamping block 6. The pressure sensor 9 is electrically connected to one of the corresponding hydraulic cylinders 5

[0021] Each individual hydraulic cylinder 5 and clamping block 6 is equipped with a pressure sensor 9 for detecting the extrusion force on the clamped tubular object. When the extrusion force exceeds the set force value, the hydraulic cylinder 5 of the currently connected clamping block 6 immediately stops extending, avoiding unnecessary damage to the tubular object. The four hydraulic cylinders 5 cooperate with the four pressure sensors 9 to operate independently for monitoring, improving the accuracy of monitoring.

[0022] The working principle of the present utility model: When a tubular object is inserted into the jack 2, at this time, the infrared sensor 7 detects the presence of the tubular object and sends a signal to the controller 8. The controller 8 synchronously activates the four hydraulic cylinders 5, and the four hydraulic cylinders 5 simultaneously drive the 6 to move to clamp the tubular object. At the same time, the pressure sensor 9 detects the extrusion force on the clamped tubular object. When the extrusion force exceeds the set force value, the hydraulic cylinder 5 of the currently connected clamping block 6 immediately stops extending, avoiding unnecessary damage to the tubular object.

[0023] The following points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. It can be a mechanical connection or an electrical connection, or it can be the communication inside two components. It can be directly connected. "Up", "down", "left", "right", etc. are only used to represent the relative position relationship. When the absolute position of the described object changes, the relative position relationship may change;

[0024] The above is only the preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the disclosure of the present utility model shall be included in the protection scope recorded in the claims.
