DETAILED DESCRIPTION

[0015] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following preferred embodiments are used to further describe the utility model in detail.

[0016] EMBODIMENT

[0017] Please refer to the attached Figures 1-3As shown, the heavy guide rail manual clamping device 2 provided by the embodiment comprises a mounting seat 5, a stroke arm 9 and a stroke bolt 10, a pair of "L"-shaped clamping arms 4 are movably arranged on the mounting seat 5, the stroke bolt 10 is fixedly connected with the middle position of the mounting seat 5, the middle part of the stroke arm 9 is movably sleeved on the stroke bolt 10, the two ends of the stroke arm 9 are movably sleeved on the clamping arms 4, the right end of the clamping arm 4 is a guide rail clamping end, the left end of the clamping arm 4 is threadedly connected with a locking nut 7, a baffle 8 and a spring 6 are sleeved on the clamping arm 4, the spring 6 is located between the baffle 8 and the stroke arm 9, the baffle 8 is located between the locking nut 7 and the spring 6, a stroke adjusting nut 11 is threadedly connected with the stroke bolt 10, the stroke adjusting nut 11 is located between the stroke arm 9 and the mounting seat 5, the mounting seat 5 is fixed on a mounting frame through a guide bolt 13, a guide ball head is arranged on the upper end of the screw rod of the guide bolt 13, a guide groove 401 is arranged on the clamping arm 4, the guide ball head and the guide groove 401 are matched and slidably arranged, and a fixed nut 12 is threadedly connected with the stroke bolt 10, the stroke adjusting nut 11 is located between the fixed nut 12 and the stroke arm 9.

[0018] Specifically, the guide groove 401 is divided into three continuous sections, the middle section is an arc section, and the first section and the second section are both linear sections. In the embodiment, the radian of the arc section is π / 2, and the arc section of the guide groove 401 can realize the rapid rotation of the clamping arm 4 by 90°. The guide rail clamping end of the clamping arm 4 is provided with a clamping plane 402.

[0019] The operation method of the heavy guide rail manual clamping device 2 for vertical guide rail installation is as follows:

[0020] Clamping operation: when the I-shaped steel guide rail 3 is rotated to the vertical position, the stroke adjusting nut 11 is manually adjusted, the stroke arm 9 moves to the left, the clamping arm 4 first linearly slides and then gradually rotates by 90° under the interaction of the guide bolt 13 and the guide groove 401, so that the guide rail clamping end clamps the I-shaped steel guide rail 3, with the further adjustment of the stroke adjusting nut 11, the I-shaped steel guide rail 3 limits the movement of the clamping arm 4 to realize clamping and compress the spring 6 to realize energy storage, and after clamping in place, the fixed nut 12 is tightened to realize fastening.

[0021] Loosening operation: first, the fixed nut 12 is loosened to release the clamping stroke, and then the stroke adjusting nut 11 is slowly loosened, under the elongation reset action of the spring 6, the clamping arm 4 releases the clamping of the I-shaped steel guide rail 3, with the further loosening of the stroke adjusting nut 11, the guide ball head of the guide bolt 13 enters the arc section of the guide groove 401, the clamping arm 4 gradually reversely rotates by 90°, and at this time, the running space of the guide rail can be released.

[0022] The above is the preferred embodiment of the utility model, which is used to explain the technical scheme of the utility model, and those skilled in the art can make routine modifications, equivalent replacements and improvements within the spirit and principles of the utility model.
