Description

Technical Field

[0001] The utility model relates to the field of testing devices, in particular to an erosion and wear testing device for a fracturing tool. Background Art

[0002] At present, the Chinese utility model with the announcement number CN202939021U discloses a fracturing tool erosion and wear test device. Its structure mainly consists of an outer cylinder, an inner joint, an outer joint, a union nut, an O-ring, a gland, a sealing gasket, a bolt, an outer locking nut, an inlet pipe fitting, an inner locking nut, a nut, a fracturing tool, a disc cover, an outlet pipe fitting, etc.; the fracturing tool is placed in the outer cylinder, and the upper and lower ends are connected to the inlet pipe fitting and the outlet pipe fitting respectively by TBG oil pipe threads; the inner locking nut, the disc cover and the outer locking nut are installed on the inlet pipe fitting from bottom to top in sequence; the gland and the outer cylinder are connected by TBG oil pipe threads. Fracturing tools of different lengths can be installed by replacing outer cylinders of different lengths, and the length of the inlet pipe fitting and the outlet pipe fitting extending into the outer cylinder can be adjusted by rotating the inlet pipe fitting and the outlet pipe fitting to meet the requirements of fracturing tool tests of different lengths, further expanding the application range of the device.

[0003] Although the existing test device can position the fracturing tool to prevent the fracturing tool from shifting during the test, there are still other problems in the use process. For example, it does not have an adjustable support function. The fracturing tool needs to be held by the personnel by hand before being fixed, and then the position is constantly adjusted to match the two positioning pipes. The installation efficiency is slow, the flexibility is poor, and it is not convenient to take and place the fracturing tool. The baffle on the outside of the device is fixed by screws. Although it is firm and reliable, tools are needed to assist in taking and placing the tool, which increases the workload of the personnel and has low practicality. In order to solve the above-mentioned problems, we propose a fracturing tool erosion and wear test device. Utility Model Content

[0004] The utility model aims to provide a fracturing tool erosion and wear test device, which solves the problem that the existing test device does not have an adjustable support function and is inconvenient to take and place the fracturing tool.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions: a fracturing tool erosion and wear testing device, comprising a box frame, both sides of the box frame are penetrated by fixed sleeves, the interiors of the two fixed sleeves are respectively threadedly connected with inlet pipe fittings and outlet pipe fittings, a U-shaped plate is bolted inside the box frame, a threaded rod is rotatably connected inside the U-shaped plate, a threaded plate is threadedly connected to the surface of the threaded rod, a support plate is welded to the front of the threaded plate through a fixing piece, a through groove is opened on the top of the box frame, a mounting frame is welded to the top of the box frame, a baffle is placed on the top of the box frame, a fixing spring is bolted between the top of the baffle and the mounting frame through a spring fixing sheet, a pull plate is arranged on the top of the mounting frame, and two connecting rods are welded between the top of the baffle and the pull plate.

[0006] The above technical solution can have an adjustable support function, which reduces the burden on personnel to hold the tool all the time, speeds up the positioning efficiency of the fracturing tool, has good flexibility, and can facilitate the fracturing tool to be taken and placed. The operation is simple and labor-saving, and no tools are required for assistance, which is highly practical.

[0007] The utility model is further configured as follows: a reinforcing plate is fixedly sleeved on the surface of the fixing sleeve, and one side of the reinforcing plate is bolted to the box frame.

[0008] By adopting the above technical solution, the fixing sleeve can be fixed by setting the reinforcing plate, thereby improving the stability between the fixing sleeve and the box frame.

[0009] The utility model is further configured as follows: a liquid inlet pipeline is passed through and communicated with the top of the box frame, and a liquid outlet pipe valve is passed through and communicated with one side of the box frame.

[0010] By adopting the above technical solution, the erosion and wear test can be performed on the outside of the fracturing tool through the arrangement of the liquid inlet pipe and the liquid outlet pipe valve.

[0011] The utility model is further configured as follows: a slide rail is bolted inside the U-shaped plate, and a sliding block slidably connected to the slide rail is welded on the back of the threaded plate.

[0012] By adopting the above technical solution, the threaded plate can be limited by setting the slide rail and the slider to prevent the threaded plate from flipping during the up and down movement.

[0013] The utility model is further configured as follows: a turning handle is welded on the other end of the threaded rod.

[0014] By adopting the above technical solution and setting the turning handle, it is convenient for a person to rotate the threaded rod by hand.

[0015] The utility model is further configured as follows: a limiting rod is welded on the top of the baffle, and the other end of the limiting rod penetrates and extends to the top of the mounting frame.

[0016] By adopting the above technical solution, the baffle can be limited by setting the limiting rod to prevent the baffle from tilting during the up and down movement.

[0017] The utility model is further configured as follows: a sealing gasket is installed at the bottom of the baffle.

[0018] By adopting the above technical solution and setting the sealing gasket, the sealing effect between the bottom of the baffle and the box frame can be improved.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model allows the user to hold the handle by hand and rotate it before use. When the handle is rotated, it drives the threaded rod to rotate through the cooperation of the bearing. When the threaded rod rotates, it drives the threaded plate to move upward through the cooperation of the slide rail and the slider. When the threaded plate moves upward, it drives the support plate to move upward together. The utility model has an adjustable support function, reduces the burden of the personnel holding the handle all the time, speeds up the positioning efficiency of the fracturing tool, and has good flexibility.

[0021] 2. The utility model uses one hand to grasp the pull plate and pull it upwards. When the pull plate is pulled upwards, the baffle plate will be driven upwards by the fixing of the connecting rod. When the pull plate is pulled to the highest point, the fracturing tool is picked up with the other hand. After being picked up, the fracturing tool is directly placed into the supporting plate through the through groove on the box frame, which can facilitate the taking and placing of the fracturing tool. The operation is simple and labor-saving, and no tools are required for assistance. It is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
