[0028] As Figures 1 to 8 Collectively shown, a test protection device for a hydraulic support column includes a box body 4. Inside the box body 4, a plurality of clamp assemblies 1 arranged vertically, a transmission assembly 2 arranged one-to-one with the clamp assembly 1, and at least one operating assembly 3 are respectively provided.

[0029] As Figures 5 to 8As shown together, each clamp assembly 1 includes a clamp fixing seat 15 fixed on the inner wall of the box body 4, a connecting shaft 13 rotatably mounted on the clamp fixing seat 15, two connecting ear plates 14 respectively arranged at both ends of the connecting shaft 13, a protective clamp arranged on the connecting shaft 13, and a reset assembly 16, and the reset assembly 16 is connected to one of the connecting ear plates 14. In this embodiment, the reset assembly 16 includes a reset base 161 fixed on the inner wall of the box body 4, a vertically arranged reset rod 162, and a reset spring 160 sleeved on the outer side of the reset rod 162, the bottom end of the reset rod 162 is fixedly connected to the reset base 161, the top end of the reset rod 162 is connected to the corresponding connecting ear plate 14, and the reset assembly 16 and the power rod 30 are respectively arranged on both sides of the protective clamp. The reset assembly 16 can reduce the lifting and pressing force required for the operating handle 32, and at the same time, the protective clamp is self-locked in the clamp protection state.

[0030] Specifically, the protective clamp includes an arc-shaped clamp body 10, a clamp rod 11 and a clamp connection seat 12, one end of the clamp rod 11 is connected to the clamp body 10, and the other end of the clamp rod 11 is connected to the clamp connection seat 12; the clamp connection seat 12 includes two connecting plates arranged opposite to each other, a connecting shaft 13 is arranged between the two connecting plates, and one end of the two connecting plates away from the clamp rod 11 is connected to the clamp fixing seat 15. In a preferred embodiment, a protective layer is arranged on the outside of the clamp body 10, and the protective layer can be a rubber layer to prevent bumps.

[0031] like Figures 5 to 8 As shown together, the transmission assembly 2 includes a transmission seat 20, a guide assembly 22 connected to the transmission seat 20, and a rotating shaft 21 rotatably arranged on the transmission seat 20, and the rotating shaft 21 is hingedly connected to the corresponding other connecting ear plate 14; in this embodiment, the guide assembly 22 includes a C-shaped guide seat 221 fixed on the inner wall of the box body 4, and a guide pin 220 arranged in the C-shaped guide seat 221, and the bottom end of the guide socket is connected to the transmission seat 20. Specifically, the transmission seat 20 includes two supporting plates 201 arranged opposite to each other and two transmission connecting plates 200 arranged at intervals, the two transmission connecting plates 200 are fixed on the outer side of one supporting plate 201, and the two transmission connecting plates 200 are connected to the power rod 30, and the rotating shaft 21 is rotatably arranged on the two supporting plates 201.

[0032] like Figures 5 to 8 As shown together, each operating assembly 3 includes a vertically arranged power rod 30, an operating handle 32 arranged on the power rod 30, and a plurality of limit seats 31 arranged on the inner wall of the box body 4 at intervals from top to bottom. The power rod 30 passes through all the limit seats 31 from top to bottom, and the power rod 30 is connected to at least one transmission seat 20; in this embodiment, the operating handle 32 is fixed to the bottom end of the power rod 30. Specifically, each power rod 30 is connected to two transmission seats 20; all power rods 30 are arranged on both sides of the clamp assembly 1.

[0033] As Figures 1 to 8 As commonly shown, after the utility model is put into use, when the hydraulic support column to be tested is placed into the box body 4, the protective clamp used can be selected according to the actual structure of the hydraulic support column. After the selection is completed, the corresponding operating handle 32 is operated to pull the corresponding power rod 30 downward, so as to drive the transmission seat 20 connected to the power rod 30 to move downward together. After the transmission seat 20 moves downward, the connecting shaft 13 of the corresponding clamp assembly 1 can be driven to rotate downward through the rotating shaft 21, so as to pull the corresponding clamp body 10 to turn over into a horizontal state to support on the side surface of the hydraulic support column. Supported by a plurality of clamp assemblies 1, the hydraulic support column will not move randomly, thus ensuring the safety during the test process.

[0034] After the test is completed, the corresponding operating handle 32 can be operated to push the power rod 30 upward, so as to drive the corresponding transmission seat 20 to move upward. The rotating shaft 21 on the transmission seat 20 then pulls the connecting shaft 13 connected thereto to rotate upward, so that the clamp body 10 turns upward under the action of the return spring 160 to be in a vertical state to avoid the hydraulic support column. At this time, the hydraulic support column can be conveniently taken out.

[0035] It can be seen that the utility model can not only reliably support the hydraulic support column, but also has the advantages of simple structure and convenient operation.

[0036] The above is only the preferred embodiment of the utility model and is not intended to limit the 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 utility model shall be included in the protection scope of the utility model.
