Description

Technical Field

[0001] The utility model relates to the technical field of petroleum fracturing testing machines, in particular to a vehicle-mounted mobile petroleum fracturing testing machine. Background Art

[0002] The oil fracturing test machine is an important equipment used in the oil industry to simulate and study the rock fracturing process. In the process of oil extraction, fracturing technology is widely used to improve the permeability of the reservoir, thereby increasing the extraction efficiency and output of oil and gas. The oil fracturing test machine provides data support for the optimization and improvement of fracturing technology by simulating actual fracturing conditions. The oil fracturing test machine usually has functions such as high pressure, high precision and automatic control. It can inject fracturing fluid into the rock sample at a set pressure to simulate the fracture and crack expansion of the rock during the actual fracturing process. By observing and recording various parameters in the fracturing process, such as pressure, flow, crack morphology, etc., researchers can analyze the fracturing characteristics of the rock, evaluate the fracturing effect, and optimize the fracturing plan.

[0003] The mobile petroleum fracturing test machine in the prior art is moved with universal wheels. However, if the universal wheels are damaged during use, it is inconvenient to replace the universal wheels, which affects the normal movement of the test machine.

[0004] For this reason, we urgently need to provide a vehicle-mounted mobile petroleum fracturing test machine. Utility Model Content

[0005] The utility model aims to provide a vehicle-mounted mobile petroleum fracturing test machine to solve the problem in the background art that after the universal wheel is damaged during use, it is inconvenient to replace the universal wheel, thereby affecting the normal movement of the test machine.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vehicle-mounted mobile petroleum fracturing test machine, comprising a fracturing test machine body, wherein movable devices are arranged around the bottom of the fracturing test machine body.

[0007] The moving device comprises a moving unit and a shock absorbing unit. The moving unit is arranged below the main body of the fracturing tester, and the shock absorbing unit is arranged at the bottom of the main body of the fracturing tester.

[0008] The mobile unit includes a side block, a handle, a support plate, a bottom plate, a mounting block, a universal wheel, a fixed spring, a clamping rod and a pull rod. The support plate is fixedly mounted on the bottom of the fracturing tester body, the side block is fixedly mounted on the front and rear ends of the right side of the support plate, the handle is fixedly mounted on the top of the front and rear side blocks, the bottom plate is arranged below the support plate, the mounting block is fixedly mounted around the bottom of the bottom plate, the upper end of the universal wheel is mounted inside the mounting block, the fixed spring is fixedly mounted on the left and right sides of the inner wall of the mounting block, the clamping rod is fixedly mounted on one end of the fixed spring, and the pull rod is fixedly mounted on one side of the clamping rod and extends to the outside of the mounting block.

[0009] Preferably, the shock absorbing unit comprises a shock absorbing spring and a damping rod, the shock absorbing spring is fixedly mounted on the top of the base plate, and the damping rod is mounted on the inner side of the shock absorbing spring.

[0010] Preferably, a connecting groove is provided inside the mounting block, and the upper end of the universal wheel is mounted inside the connecting groove, so that the universal wheel is conveniently connected to the mounting block through the connecting groove.

[0011] Preferably, the left and right sides of the upper end of the universal wheel are provided with clamping holes with the same diameter as the clamping rod. After the upper end of the universal wheel enters the interior of the mounting block, the clamping rod is clamped with the clamping holes of the universal wheel to fix the universal wheel.

[0012] Preferably, the shock-absorbing spring and the top of the damping rod are fixedly connected to the bottom of the support plate. During the movement of the fracturing test machine body, when the fracturing test machine body is vibrated, the shock-absorbing spring and the damping rod are squeezed by the support plate to reduce the vibration of the fracturing test machine body, thereby preventing the fracturing test machine body from being subjected to excessive vibration during movement and causing damage to internal components.

[0013] Preferably, one end of the clamping rod away from the pull rod is hemispherical, so as to facilitate the clamping connection between the clamping rod and the universal wheel.

[0014] Preferably, positioning blocks are provided on the front and rear sides of the inner wall of the connecting groove formed by the mounting block, and positioning grooves of the same size as the positioning blocks are provided on the front and rear sides of the upper end of the universal wheel. When installing the universal wheel, the universal wheel cooperates with the positioning blocks so that the clamping rod and the clamping hole formed on the upper end of the universal wheel are located in the same straight line, thereby facilitating the clamping connection between the clamping rod and the clamping hole, thereby improving the installation efficiency of the universal wheel.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The vehicle-mounted mobile oil fracturing test machine is provided with a moving unit. When the universal wheel is damaged and needs to be replaced, the pull rod is pulled outward to drive the clamping rod to squeeze the fixing spring until the clamping rod moves out of the clamping hole of the universal wheel, and then the damaged universal wheel is pulled out downward. Then, the positioning groove opened at the upper end of the universal wheel to be replaced is connected with the positioning block, and then the universal wheel is pushed upward to move along the positioning block. When the upper end of the universal wheel contacts the inner wall of the mounting block, the pull rod is released, and the clamping rod is pushed to engage with the clamping hole of the universal wheel under the action of the fixing spring, thereby fixing the universal wheel and completing the replacement of the universal wheel. This solves the problem in the background technology that after the universal wheel is damaged during use, it is inconvenient to replace the universal wheel, thereby affecting the normal movement of the test machine.

[0017] 2. The vehicle-mounted mobile petroleum fracturing test machine is provided with a shock-absorbing unit. When the fracturing test machine body is vibrated during movement, the shock-absorbing spring and the damping rod are squeezed by the support plate to reduce the vibration of the fracturing test machine body, thereby preventing the fracturing test machine body from being subjected to excessive vibration during movement, thereby preventing damage to internal components.
