[0023] In order to make the technical means, creation features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0024] As Figures 1 to 4As shown, an elevator counterweight clamping device according to an embodiment of the present invention includes a support frame 1; a plurality of counterweight blocks 12 are installed in the middle of the support frame 1; a first clamping frame 13 is installed on the top of the plurality of counterweight blocks 12; a connecting pipe 14 is fixedly connected to the bottom of the first clamping frame 13; a second clamping frame 15 is installed at the bottom of the support frame 1; a screw 16 is fixedly connected to the top of the second clamping frame 15; a threaded sleeve 17 is rotatably connected to the bottom end of the connecting pipe 14; the threaded sleeve 17 and the screw 16 are threadedly engaged; during operation, after the plurality of counterweight blocks 12 are installed on the support frame 1, the first clamping frame 13 and the second clamping frame 15 are clamped together. 5 are respectively placed above the counterweight block 12 and below the bearing frame 1, and the screw 16 is inserted into the connecting pipe 14. By rotating the screw sleeve 17, the screw 16 and the connecting pipe 14 are connected by the threaded engagement between the screw sleeve 17 and the screw 16. As the screw sleeve 17 rotates, the first clamping frame 13 and the second clamping frame 15 move closer to each other and press the multiple counterweight blocks 12 tightly onto the bearing frame 1. With the above structure, the counterweight blocks can be pressed without opening a hole in the middle of the bearing frame 1, reducing the impact of opening a hole in the middle of the bearing frame 1 on the structural strength of the bearing frame 1 and improving the safety of elevator operation.

[0025] like Figures 1 to 3 As shown, a third clamping frame 2 is slidably connected to both sides of the first clamping frame 13; an elastic rope 21 is fixedly connected to the middle of the third clamping frame 2; the other end of the elastic rope 21 is fixedly connected to the middle of the first clamping frame 13; an adjusting bolt 22 is threadedly connected to the middle of the elastic rope 21; a pressing plate 23 is installed between the adjusting bolt 22 and the multiple counterweight blocks 12; during operation, after the first clamping frame 13 and the second clamping frame 15 are connected through the screw sleeve 17 and the screw 16, a pair of third clamping frames 2 are fastened to the two side columns of the bearing frame 1, and then the height of the multiple counterweight blocks 12 is adjusted according to the stacking height. A compression plate 23 of the appropriate length is inserted between the adjusting bolt 22 and the multiple counterweight blocks 12. Then, the adjusting bolt 22 is rotated so that the adjusting bolt 22 drives the compression plate 23 to press against the side wall of the multiple counterweight blocks 12, so that the multiple counterweight blocks 12 are pressed and tightly fitted against the inner side wall of the bearing frame 1, thereby further reducing the swaying of the multiple counterweight blocks 12 during elevator operation. Through the above structure, the pressing effect of the counterweight blocks 12 can be further improved, the swaying of the multiple counterweight blocks 12 during elevator operation can be reduced, and the adverse effects caused by the swaying of the counterweight blocks 12 can be reduced.

[0026] like Figures 1 to 4As shown, the side wall of the first clamping frame 13 is fixedly connected with a guide rail 3; the middle part of the guide rail 3 is slidingly connected with a ratchet seat 31; the middle part of the ratchet seat 31 is rotatably connected with a ratchet sleeve 32; the ratchet sleeve 32 and the ratchet seat 31 are provided in ratchet cooperation; in work, after the compression of the plurality of counterweight bodies 12 is completed, the ratchet sleeve 32 is rotated and the ratchet seat 31 is slid downward, so that the ratchet sleeve 32 is sleeved in the middle part of the screw sleeve 17; since the ratchet sleeve 32 cannot be easily reversed, the screw sleeve 17 cannot be easily reversed due to vibration and the like, so that the plurality of counterweight bodies 12 cannot be easily loosened due to the decrease of the compression force. Through the above structure, the screw sleeve 17 cannot be easily rotated, and the loosening of the plurality of counterweight bodies 12 due to the decrease of the compression force can be reduced.

[0027] As shown in Figures 1 to 3 , the end of the adjusting bolt 22 is rotatably connected with a rotating disc 4; the side wall of the rotating disc 4 is fixedly connected with a plurality of bevel gears 41; the extrusion plate 23 is made of wood; in work, the rotating disc 4 is extruded on the extrusion plate 23 by rotating the adjusting bolt 22, at this time the plurality of bevel gears 41 will pierce into the inside of the extrusion plate 23, so that after the adjusting bolt 22 is reversed and the extrusion plate 23 is loosened due to the decrease of the compression force in the long-term use process, the extrusion plate 23 cannot be easily slid off, and the wood extrusion plate 23 has certain toughness, which can reduce the loosening of the adjusting bolt 22 due to vibration and improve the stability of the device in long-time operation.

[0028] As shown in Figure 4 , the top end of the guide rail 3 is fixedly connected with a magnet 5; the ratchet seat 31 is made of magnetic material; in work, when the screw sleeve 17 is adjusted by rotating, the ratchet seat 31 can be slid upward along the guide rail 3 and be attracted by the magnet 5, so that the ratchet seat 31 cannot be easily slid off, thereby reducing the hindrance caused by the rotation adjustment of the screw sleeve 17 and improving the use convenience of the device.

[0029] As shown in Figure 5 , a pair of rubber pads 6 is installed between each pair of adjacent counterweight bodies 12; the pair of rubber pads 6 is respectively located at both ends of the counterweight body 12; in work, when the plurality of counterweight bodies 12 are installed, impurities are likely to exist between the plurality of counterweight bodies 12, and in the long-term use process, the impurities may be broken to reduce the gap between the plurality of counterweight bodies 12 and cause the plurality of counterweight bodies 12 to be loosened; by providing the rubber pads 6 between the plurality of counterweight bodies 12, the gap between the plurality of counterweight bodies 12 cannot be easily changed after the plurality of counterweight bodies 12 are compressed, and the elasticity provided by the plurality of rubber pads 6 can provide a reaction force for the first clamping frame 13 and the second clamping frame 15, so that the plurality of counterweight bodies 12 compressed are more difficult to be loosened, and the compression effect of the device is improved.

[0030] As shown in Figure 5As shown, the top and bottom of the rubber pad 6 are provided with a plurality of grooves 7; the plurality of grooves 7 on the top and bottom of the rubber pad 6 are arranged in a staggered manner; through the above structure, the deformation adaptability of the rubber pad 6 can be improved, and the influence of the largest impurities on the top or bottom of the rubber pad 6 on the most upper counterweight block 12 and the compression effect of the device can be reduced.

[0031] In operation, after the plurality of counterweight blocks 12 are installed on the bearing frame 1, the first clamping frame 13 and the second clamping frame 15 are respectively arranged above the counterweight blocks 12 and below the bearing frame 1, and the screw rod 16 is inserted into the connecting pipe 14, the connection between the screw rod 16 and the connecting pipe 14 is realized by rotating the screw sleeve 17 through the thread cooperation between the screw sleeve 17 and the screw rod 16, and the first clamping frame 13 and the second clamping frame 15 are moved closer to each other and tightly press the plurality of counterweight blocks 12 on the bearing frame 1 by rotating the screw sleeve 17. After the first clamping frame 13 and the second clamping frame 15 are connected by the screw sleeve 17 and the screw rod 16, a pair of third clamping frames 2 are buckled on the two side columns of the bearing frame 1, then according to the height of the plurality of counterweight blocks 12, the corresponding length of the extrusion plate 23 is selected and inserted between the adjusting bolt 22 and the plurality of counterweight blocks 12, and then the adjusting bolt 22 is rotated to make the adjusting bolt 22 drive the extrusion plate 23 to extrude the sidewall of the plurality of counterweight blocks 12, so that the plurality of counterweight blocks 12 are tightly attached to the inner sidewall of the bearing frame 1, thereby further reducing the shaking of the plurality of counterweight blocks 12 during the operation of the elevator. After the plurality of counterweight blocks 12 are compressed, the ratchet sleeve 32 is rotated and the ratchet seat 31 is lowered, so that the ratchet sleeve 32 is sleeved in the middle of the screw sleeve 17. Since the ratchet sleeve 32 cannot easily rotate in the opposite direction, the screw sleeve 17 cannot easily rotate in the opposite direction due to vibration, so that the pressure of the plurality of counterweight blocks 12 is reduced and loosened. The rotation of the adjusting bolt 22 causes the rotating disc 4 to extrude the extrusion plate 23, and at this time the bevel gears 41 will penetrate into the inside of the extrusion plate 23, so that the extrusion plate 23 will not easily slide off after the adjusting bolt 22 is reversed and the pressure of the extrusion plate 23 is reduced during long-term use. When adjusting the rotation of the screw sleeve 17, the ratchet seat 31 can be slid along the guide rail 3 and be attracted by the magnet 5 to prevent it from easily sliding off, thereby reducing the obstruction caused by the rotation adjustment of the screw sleeve 17. When installing the plurality of counterweight blocks 12, impurities may exist between the plurality of counterweight blocks 12, which may break and cause the gap between the plurality of counterweight blocks 12 to decrease, causing the plurality of counterweight blocks 12 to loosen. By arranging the rubber pad 6 between the plurality of counterweight blocks 12, the gap between the plurality of counterweight blocks 12 will not easily change after the plurality of counterweight blocks 12 are compressed, and the elasticity provided by the plurality of rubber pads 6 can provide a reaction force for the first clamping frame 13 and the second clamping frame 15, so that the plurality of counterweight blocks 12 are more difficult to loosen after being compressed.

[0032] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
