Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinder testing, in particular to an adjustable small oil cylinder loading test bench. Background Art

[0002] After the maintenance of the small oil cylinder of the hydraulic support is completed, it is necessary to perform a pressure test on the oil cylinder to detect whether the oil cylinder will have liquid hanging, liquid seepage and other phenomena. The existing patent (Announcement No.: CN217107687U) discloses an adjustable small oil cylinder loading test bench. The utility model supports the oil cylinder by setting a rotating wheel and a load-bearing rod, and after the test is completed, the leakage in the placement groove can be cleaned by taking out the load-bearing rod and the rotating wheel, which is convenient for subsequent tests. However, in actual applications, since the oil cylinder is actually installed at the end of the placement groove, even if the oil cylinder is placed in the placement groove by hoisting, the staff still needs to enter the placement groove to assemble the oil cylinder and the oil cylinder connector, which is not convenient for installing the test cylinder. For this reason, we propose an adjustable small oil cylinder loading test bench. Utility Model Content

DETAILED DESCRIPTION

[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: an adjustable small oil cylinder loading test bench, including an adjustable small oil cylinder loading test bench, including a test bench body 2 installed on the top of a support platform 1, a working groove 15 is provided in the test bench body 2, a rolling support mechanism is provided in the working groove 15, and a loading seat 4 is spliced ​​at one end of the test bench body 2;

[0021] Furthermore, the docking parts of the test bench body 2 and the loading seat 4 are both provided with assembly plates 8, and the corresponding assembly plates 8 are connected by fasteners; by connecting the assembly plates 8, the test bench body 2 and the loading seat 4 are installed;

[0022] The loading seat 4 is connected to a mounting plate 6 that can move up and down;

[0023] Further, a mounting groove 5 is provided on one side of the loading seat 4 close to the test bench body 2, and a connecting groove docking with the mounting groove 5 is provided at the end of the test bench body 2. A vertically arranged screw rod 9 is movably connected in the mounting groove 5. Both upper and lower ends of the screw rod 9 are movably installed with the inner wall of the mounting groove 5, and the top of the screw rod 9 passes through the mounting groove 5. A slider 10 fixed to the mounting plate 6 is threadedly connected on the screw rod 9. By rotating the screw rod 9, the slider 10 moves up and down along the screw rod 9, and drives the mounting plate 6 to move up and down. Due to the different volumes of the test cylinders, when the cylinders are placed horizontally in the working groove 15, the heights of the cylinder piston rods are different. By adjusting the position of the mounting plate 6, the mounting plate 6 can be connected to the cylinder;

[0024] Furthermore, guide rods 11 fixed in the mounting grooves 5 are provided on both sides of the screw rod 9, the mounting plate 6 is slidably connected to the guide rods 11, and sliding sleeves adapted to the guide rods 11 are installed on the guide rods; the guide rods 11 are used to effectively support the mounting plate 6, thereby improving the stability of the mounting plate 6 when moving.

[0025] A connecting seat 7 assembled with the oil cylinder piston rod is fixed on the mounting plate 6, and the mounting plate 6 is connected with the working groove 15;

[0026] Specifically, by setting the test bench body 2, the loading seat 4 and the mounting plate 6, when testing the oil cylinder, first connect the piston rod end of the oil cylinder to the mounting plate 6, then move the loading seat 4 by hoisting to dock with the test bench body 2, place the oil cylinder body in the working groove 15 in the test bench body 2, and finally connect the oil cylinder to the corresponding oil pipe. After the connection is completed, conduct the experiment. Compared with the prior art, the oil cylinder is first assembled with the loading seat 4, and then the oil cylinder is placed in the working groove 15. There is no need for the staff to enter the working groove 15 to install the oil cylinder, which is convenient for installation.

[0027] A loading mechanism 14 is provided above the test bench body 2. The loading mechanism 14 is responsible for performing pressure testing on the test cylinder. The loading mechanism 14 is driven by the linear motion mechanism 12 to perform linear reciprocating motion along the test bench body 2. A hydraulic control box 3 is provided at the other end of the test bench body 2.

[0028] Specifically, the linear motion mechanism 12 includes a screw rod and a limit rod respectively located on both sides of the test bench body 2, support plates are provided at both ends of the screw rod and the limit rod, the screw rod and the support plate are movably connected, the limit rod and the support plate are fixed, a slide 1 is threadedly connected to the screw rod, and a slide 2 is slidably connected to the limit rod, and the loading mechanism 14 is installed between the slide 1 and the slide 2. By rotating the screw rod, the slide 1 can be moved along the screw rod, thereby driving the loading mechanism 14 to move. During the actual test, since the end position of the cylinder piston rod is fixed, the hydraulic pressure is used to extend or shorten the piston rod. At this time, the cylinder body translates in the working groove 15, so that the loading mechanism 14 adapts to the position of the cylinder body for testing;

[0029] Furthermore, a limit ring 16 is evenly fixed on one end of the test bench body 2 close to the hydraulic control box 3, and a limit ring 2 17 is evenly fixed on both sides of the test bench body 2; the oil cylinder is connected to the hydraulic control box 3 through an oil pipe, so as to control the length of the oil cylinder piston rod, and the limit ring 16 and the limit ring 2 17 are used to limit the long oil pipe to avoid winding;

[0030] Furthermore, a liquid collecting tank 18 communicating with the working groove 15 is provided at the bottom of the test bench body 2, a liquid discharge port connected to the liquid collecting tank 18 is provided through the bottom of the working groove 15, the liquid collecting tank 18 is installed with the test bench body 2 through a connecting plate 19, and the liquid collecting tank 18 is connected to the liquid discharge pipe 13;

[0031] Furthermore, the end surface of the loading seat 4 and the test bench body 2 is set as an inclined surface, and the distance between the top of the loading seat 4 and the hydraulic control box 3 is shorter than the distance between the bottom and the hydraulic control box 3; thereby preventing a large amount of accumulated liquid in the working groove 15 from flowing upward along the inclined surface into the loading seat 4, thereby reducing the difficulty of cleaning;

[0032] Specifically, by setting up a liquid collecting tank 18 and a drain pipe 13, the liquid collecting tank 18 is used to collect the leaked liquid during the oil cylinder test, and the drain pipe 13 is used to discharge the liquid in the liquid collecting tank 18. The working groove 15 can also be cleaned by flushing with water, and then the clean sewage is discharged through the liquid collecting tank 18 and the drain pipe 13, which is convenient for cleaning.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
