Description

Technical Field

[0001] The utility model relates to the technical field of test devices, in particular to a test protection device for a hydraulic support column. Background Art

[0002] A hydraulic support includes a front column and a rear column. Before the front column and the rear column are put into use, a pressure injection test needs to be carried out. Based on this, a test device appears. Usually, the test device includes a box body, the box body includes a door panel, and a pressure injection device is arranged in the box body. Moreover, when conducting a test, the door panel needs to be closed, and it is necessary to ensure that the door panel will not be opened randomly during the test process, because once the door panel is opened, it is easy to cause injury and trigger a safety accident.

[0003] In view of the above technical problems, those skilled in the art urgently need to design a test protection device to ensure that the door panel will not be opened randomly during the test process. Summary of the Utility Model

[0004] In view of the above deficiencies, the technical problem to be solved by the utility model is: to provide a test protection device for a hydraulic support column. A locking pin mechanism is arranged on the door panel of the device, and the locking pin mechanism can ensure that the door panel will not be opened randomly, thereby ensuring that no injury or other incidents will occur during the test process and improving the safety of the test.

[0005] To solve the above technical problems, the technical solution of the utility model is:

[0006] A test protection device for a hydraulic support column includes a box body. The box body includes a door frame and a door panel hinged to the door frame. A hand wheel is arranged on the outer side of the door panel; a locking pin mechanism is arranged on the inner side of the door panel. The locking pin mechanism includes a cam-type counterweight, a vertically arranged linkage rod, a connecting component connecting the cam-type counterweight and the linkage rod, and at least one locking pin component. The cam-type counterweight is coaxially arranged with the hand wheel; each locking pin component includes a connecting plate and a locking pin. The locking pin and the linkage rod are arranged in parallel, and the connecting plate is arranged between the linkage rod and the locking pin. The top end of the locking pin is connected to the connecting plate; a fixing plate arranged in one-to-one correspondence with the locking pin component is arranged on the door frame. A locking pin hole is arranged on the fixing plate, and the locking pin hole is arranged vertically opposite to the bottom end of the locking pin; by rotating the hand wheel, the hand wheel drives the cam-type counterweight to rotate, the cam-type counterweight drives the linkage rod to move up and down through the connecting component, and then drives each locking pin to move up and down, so that the locking pin is disengaged from or inserted into the corresponding locking pin hole, realizing the disassembly and connection of the door panel and the door frame.

[0007] Preferably, the locking pin mechanism further includes at least one limiting component. Each limiting component includes a limiting block fixed on the door frame and a limiting plate covering the limiting block. A limiting groove is provided on the limiting block, and the linkage rod is accommodated in the limiting groove.

[0008] Preferably, the locking pin mechanism includes the limiting components arranged in one-to-one correspondence with the locking pin components. A limiting through hole is provided on each limiting block, and a corresponding locking pin is arranged in the limiting through hole, and the limiting block is arranged below the connecting plate.

[0009] Preferably, the connecting component includes a connecting frame, a connecting shaft arranged at one end of the connecting frame, two connecting rods arranged in parallel up and down, and a connecting block; the other end of the connecting frame is connected to the cam-type counterweight; the connecting shaft is arranged between the two connecting rods; the two connecting rods are both horizontally arranged, and one end of each connecting rod is fixedly connected to the connecting block; the connecting block is fixedly connected to the linkage rod.

[0010] Preferably, the hand wheel and the cam-type counterweight are coaxially arranged through a cylindrical shaft.

[0011] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows:

[0012] Since the test protection device for the hydraulic support column of the present utility model includes a box body, the box body includes a door frame and a door panel hinged to the door frame, and a hand wheel is arranged on the outer side of the door panel; a locking pin mechanism is arranged on the inner side of the door panel, and the locking pin mechanism includes a cam-type counterweight, a vertically arranged linkage rod, a connecting component connecting the cam-type counterweight and the linkage rod, and at least one locking pin component. The cam-type counterweight is coaxially arranged with the hand wheel; each locking pin component includes a connecting plate and a locking pin. The locking pin and the linkage rod are arranged in parallel, and the connecting plate is arranged between the linkage rod and the locking pin, and the top end of the locking pin is connected to the connecting plate; a fixing plate arranged in one-to-one correspondence with the locking pin component is provided on the door frame, and a locking pin hole is provided on the fixing plate, and the locking pin hole is vertically opposite to the bottom end of the locking pin. During actual use, the hand wheel is rotated on the outer side of the box body, the hand wheel drives the cam-type counterweight connected thereto to rotate, and after the cam-type counterweight rotates, it drives the linkage rod to move up and down through the connecting component, and then drives each locking pin to move up and down, so that the locking pin is disengaged from or inserted into the corresponding locking pin hole, realizing the disassembly and connection of the door panel and the door frame. Because the cam-type counterweight has weight, after the locking pin is inserted into the locking pin hole, the linkage rod will not move upward randomly, that is, the locking pin will not easily disengage from the locking pin hole. Therefore, the locking pin mechanism of the present utility model can reliably connect the door panel and the door frame together, thereby preventing injury caused by opening the door during the test process.

[0022] Such as Figures 1 to 16As shown together, a test protection device for a hydraulic support column includes a box body, the box body includes a door frame 2 and a door panel 1 hinged to the door frame 2, and a handwheel 3 is arranged on the outer side of the door panel 1; a locking pin mechanism 4 is arranged on the inner side of the door panel 1, and the locking pin mechanism 4 includes a cam-type counterweight 41, a vertically arranged linkage rod 45, a connecting component connecting the cam-type counterweight 41 and the linkage rod 45, and at least one locking pin component. The cam-type counterweight 41 is coaxially arranged with the handwheel 3; in this embodiment, the handwheel 3 and the cam-type counterweight 41 are coaxially arranged through a cylindrical shaft 40, and shaft discs are respectively arranged at both ends of the cylindrical shaft 40.

[0023] As Figures 7 to 16 As shown together, each locking pin component includes a connecting plate 47 and a locking pin 46. The locking pin 46 and the linkage rod 45 are arranged in parallel, and the connecting plate 47 is arranged between the linkage rod 45 and the locking pin 46. The top end of the locking pin 46 is connected to the connecting plate 47; in this embodiment, the locking pin mechanism 4 includes a plurality of locking pin components, such as four, and all the locking pin components are arranged at intervals up and down so as to reliably connect the door panel 1 and the door frame 2 together.

[0024] In this embodiment, the connecting component includes a connecting frame 42, a connecting shaft 48 arranged at one end of the connecting frame 42, two connecting rods 43 arranged in parallel up and down, and a connecting block 44; the other end of the connecting frame 42 is connected to the cam-type counterweight 41; the connecting shaft 48 is arranged between the two connecting rods 43; both of the two connecting rods 43 are horizontally arranged, and one end of each connecting rod 43 is fixedly connected to the connecting block 44; the connecting block 44 is fixedly connected to the linkage rod 45. In addition, the connecting frame 42 includes two connecting plates arranged at intervals. One end of the connecting plate is welded to the cam-type counterweight 41, and the other end of the connecting plate is welded to the connecting shaft 48.

[0025] As Figures 2 to 10 As shown together, a fixing plate 5 arranged in one-to-one correspondence with the locking pin component is arranged on the door frame 2, a locking pin hole 50 is arranged on the fixing plate 5, and the locking pin hole 50 is arranged up and down opposite to the bottom end of the locking pin 46.

[0026] As Figures 7 to 10 As shown together, in this embodiment, the locking pin mechanism 4 further includes at least one limiting component. Each limiting component includes a limiting block 60 fixed on the door frame 2 and a limiting plate 61 covering the limiting block 60. A limiting groove is arranged on the limiting block 60, and the linkage rod 45 is accommodated in the limiting groove.

[0027] In a preferred embodiment, the locking pin mechanism 4 includes a limiting component provided in a one-to-one correspondence with the locking pin assembly. A limiting through-hole is provided on each limiting block 60, and a corresponding locking pin 46 is provided in the limiting through-hole. The limiting block 60 is provided below the connecting plate 47. In addition, the limiting plate 61 is connected to the limiting block 60 through a locking component. Of course, the limiting structure 6 is not limited to those listed above, as long as it can restrict the linkage rod 45 to move vertically up and down.

[0028] As Figures 1 to 16 As commonly shown, when the test protection device for the hydraulic support column of the present utility model is put into use, the handwheel 3 can be rotated outside the door panel 1. The handwheel 3 drives the cam-type counterweight block 41 connected thereto to rotate through the cylindrical shaft 40. After the cam-type counterweight block 41 rotates, it specifically drives two connecting rods 43 through the connecting frame 42, that is, through the connecting shaft 48.

[0029] When the connecting frame 42 drives the two connecting rods 43 to move upward, the two connecting rods 43 drive the linkage rod 45 to move upward through the connecting block 44. The linkage rod 45 moves upward reliably under the constraint of the limiting structure 6, and at the same time drives the corresponding locking pin 46 to move upward through the connecting plate 47, so that the locking pin 46 disengages from the corresponding locking pin hole 50. At this time, the door panel 1 can be opened.

[0030] When the connecting frame 42 drives the two connecting rods 43 to move downward, the two connecting rods 43 drive the linkage rod 45 to move downward through the connecting block 44. The linkage rod 45 moves downward reliably under the constraint of the limiting structure 6, and at the same time drives the corresponding locking pin 46 to move downward under the constraint of the limiting block 60 through the connecting plate 47 and insert into the corresponding locking pin hole 50. At this time, the door panel 1 is reliably connected to the door frame 2. At the same time, under the action of the gravity of the cam-type counterweight block 41, the linkage rod 45 will not move randomly, thus ensuring that the door panel 1 will not be easily opened, and further ensuring the safety during the test process.

[0031] Therefore, the locking pin mechanism 4 of the present utility model can reliably connect the door panel 1 to the door frame 2, thereby preventing injury caused by opening the door during the test process. Moreover, the structure of the present utility model is simple and easy to implement.

[0032] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modification, equivalent improvement of a test protection device for a hydraulic support column, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
