DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0019] The prefabricated beam mid-span partition plate adjusting model comprises a bottom plate 20, the bottom plate 20 is internally provided with an adjusting member, the adjusting member comprises a double-shaft motor 21 arranged at the middle position of the bottom plate 20, the output ends of the double-shaft motor 21 are fixedly sleeved with fixed shafts, one end of the fixed shaft away from the double-shaft motor 21 is fixedly sleeved with a conical gear one 23,

[0020] Two groups of support assemblies are arranged on the two sides of the top of the bottom plate 20, and each support assembly comprises an outer sleeve 30 arranged on the top of the bottom plate 20 and a one-way lead screw 31 rotatably and telescopically arranged in the outer sleeve 30. An inner sleeve 32 is threadedly sleeved on the outer surface of the one-way lead screw 31 in the inner part of the outer sleeve 30. The bottom part of the one-way lead screw 31 penetrates the bottom part of the outer sleeve 30 and the top of the bottom plate 20 in sequence and extends into the bottom plate 20. A conical gear II 33 is fixedly sleeved on the end of the one-way lead screw 31 extending into the bottom plate 20. The adjusting member drives the conical gear II 33 to rotate, so as to control the one-way lead screw 31 to drive the inner sleeve 32 to reciprocate in the vertical direction. The conical gear I 23 is in meshing connection with the conical gear II 33. The support plate 10 is detachably arranged on the top of the two groups of support assemblies.

[0021] When the double-shaft motor 21 is started, the two output ends thereof rotate synchronously. Since the output ends are fixedly sleeved with the fixed shafts, and the fixed shafts are fixedly sleeved with the conical gear I 23, the rotation of the double-shaft motor 21 drives the conical gear I 23 to rotate. Since the conical gear I 23 is in meshing connection with the conical gear II 33, when the conical gear I 23 rotates, the conical gear II 33 in meshing connection with the conical gear I 23 is driven to rotate. Since the conical gear II 33 is fixedly sleeved on the one-way lead screw 31, the rotation of the conical gear II 33 drives the one-way lead screw 31 to rotate synchronously. The one-way lead screw 31 is in threaded sleeving connection with the inner sleeve 32, and the inner sleeve 32 is limited to move in the vertical direction along the outer sleeve 30. When the one-way lead screw 31 rotates, the inner sleeve 32 reciprocates in the vertical direction. Therefore, the adjusting member can drive the two groups of support assemblies to rotate synchronously, so as to ensure that the support plate 10 always maintains a horizontal state, to ensure that the support force received by the cross partition plate is uniform and balanced, and to improve the effect of support stability.

[0022] In an embodiment, a U-shaped plate 22 is fixedly installed on the inner wall of the bottom plate 20. The U-shaped plate 22 is in rotational connection with the fixed shaft. The U-shaped plate 22 can provide reliable support for the fixed shaft, to prevent the fixed shaft from shaking or deviating during rotation, so that the fixed shaft, the output end of the double-shaft motor 21 and the conical gear I 23 maintain concentricity.

[0023] In an embodiment, a positioning sleeve 11 matched with the top of the inner sleeve 32 is fixedly connected to the bottom of the support plate 10. The top of the inner sleeve 32 is telescopically arranged in the positioning sleeve 11. The positioning sleeve 11 can realize the mounting and dismounting of the inner sleeve 32 on the support plate.

[0024] In one embodiment, the support plate 10 is movably inserted with multiple groups of T-shaped supports 12 on both sides, and the multiple groups of supports 12 on the same side of the support plate 10 are fixedly connected with connecting rods 14, a bidirectional screw rod 13 is rotatably inserted in the middle of the support plate 10, and both ends of the bidirectional screw rod 13 respectively penetrate through two groups of connecting rods 14 and are threadedly connected with the connecting rods 14;

[0025] Specifically, when the bidirectional screw rod 13 is rotated, since the bidirectional screw rod 13 is threadedly connected with the connecting rods 14 on both sides, and the connecting rods 14 are limited by the T-shaped supports 12 to only move along the width direction of the support plate 10, when the bidirectional screw rod 13 is rotated, the two groups of connecting rods 14 will move in the direction of moving away from each other or moving close to each other along the bidirectional screw rod 13, and the multiple groups of T-shaped supports 12 will synchronously move with the movement of the connecting rods 14, so that the area of supporting the cross partition plate can be increased.

[0026] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit it.
