Description

Technical Field

[0001] This utility model relates to the field of elevator counterweight technology, and in particular to a counterweight assembly that facilitates the addition or removal of counterweights. Background Technology

[0002] The elevator counterweight is an important component of the elevator traction system. Its function is to support the counterweight and connect it to the traction rope. By balancing the weight of the car, it reduces the power of the traction motor and the torque on the traction sheave and worm gear, thereby improving the elevator's operating efficiency and safety.

[0003] The existing counterweight frame is assembled by clamping the counterweight between two side plates and fixing it to the support frame. Then, the top of the two side plates and the top frame are connected by bolts. This assembly method means that when adding or removing counterweights, the entire counterweight frame needs to be disassembled, and then reassembled after the counterweights are added or removed. The whole process involves many steps, is cumbersome, and has low work efficiency. Utility Model Content

[0004] This utility model addresses the problem that in the prior art, adding or removing counterweights requires disassembling the entire counterweight frame, then adding or removing the counterweights, and then reassembling them. This process involves many steps, is cumbersome, and has low work efficiency. Therefore, this utility model proposes a counterweight assembly that facilitates the addition and removal of counterweights.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a counterweight assembly for convenient addition and removal of counterweights, comprising a support frame, side plates symmetrically and slidably mounted on the support frame, a common top frame slidably mounted on one end of the two side plates, a plurality of counterweight bodies disposed between the two side plates, the plurality of counterweight bodies being placed on the top of the support frame, and a quick-release device disposed between the two side plates, the quick-release device using two threaded rods in a threaded cylinder to drive the two side plates to move horizontally to achieve the operation of limiting and releasing the counterweight bodies.

[0006] The effect achieved by the above-mentioned components is that by setting a threaded rod to drive the side plate to move in the horizontal direction, the limitation of the side plate on the counterweight body is released, without the need to disassemble the entire counterweight frame, reducing the number of operation steps, and thus effectively improving the work efficiency of adding or removing counterweights.

[0007] Preferably, the quick-release device includes a rectangular tube, which is disposed on top of one of the counterweight bodies. Rectangular rods are symmetrically and slidably installed on the inner wall of the rectangular tube. One end of the rectangular rod is slidably installed on the inner wall of the side plate. A threaded cylinder is fixedly installed on one side of the rectangular tube. Threaded rods are symmetrically threaded on the inner wall of the threaded cylinder. A threaded hole plate is rotatably connected to the outer surface of the threaded rod through a bearing. The threaded hole plate is slidably installed on one side of the side plate.

[0008] The aforementioned components achieve the following effect: by pushing the rectangular cylinder to slide the rectangular rod along the inner wall of the side plate until the bottom of the rectangular cylinder abuts against the top of the counterweight body, the two threaded rods are then rotated, causing them to extend and retract along the inner wall of the threaded cylinder, simultaneously moving the side plate horizontally until both ends of several counterweights are fully inserted into the inner walls of the two side plates, thus completing the assembly of the counterweights. Furthermore, when it is necessary to add or remove counterweights, simply rotate the two threaded rods in the opposite direction to move the side plate away from the counterweights, causing both sides of the counterweights to lose their restraints. Then, push the rectangular cylinder upwards to remove the top of the counterweights, allowing for the addition or removal of the counterweight body.

[0009] Preferably, an extension block is fixedly installed at one end of the screw hole plate, one side of the extension block abuts against one side of the side plate, and a bolt is threaded into the inner wall of the extension block.

[0010] The effect achieved by the above components is as follows: by rotating the bolt, one end of the bolt abuts against one side of the side plate, the bolt hole plate and the side plate can be fixed, thereby fixing the rectangular tube and the rectangular plate in the vertical direction, which helps to prevent the rectangular tube from shifting and causing the counterweight body to fall out of the limit position of the rectangular tube.

[0011] Preferably, a rubber strip is adhered to the inner wall of one side of the side plate, and the bolt is located on one side of the rubber strip.

[0012] The effect achieved by the above components is that by setting a rubber strip to replace one side of the side plate and abut against one end of the bolt, the friction between the bolt and the side plate can be increased, thereby making the bolt more securely fixed to the rectangular tube.

[0013] Preferably, an operating block is fixedly installed at one end of the threaded rod, and the outer surface of the operating block is provided with protrusions.

[0014] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded rod to rotate on the inner wall of the threaded cylinder. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0015] Preferably, auxiliary components are provided on both sides of the rectangular tube. The auxiliary components include a first baffle and a second baffle. The first baffle is fixedly installed on one side of the rectangular tube, and a locking block is fixedly installed on the other side of the rectangular tube. One side of the locking block abuts against one side of the second baffle. One side of the first baffle and the second baffle abuts against both sides of a plurality of counterweight bodies, respectively.

[0016] The effect achieved by the above components is as follows: when the two side plates are fully in contact with both ends of the counterweight body, the counterweight body is difficult to detach from the two side plates. However, when the counterweight is disassembled or assembled, the two side plates separate from each other and move away from the counterweight body, and the counterweight loses its limiting position. The presence of the first baffle and the second baffle can limit the top few counterweight bodies respectively, while the bottom few counterweight bodies are difficult to move under the pressure of the weight of the top few counterweight bodies, which helps to prevent the counterweight body from falling during the adjustment of the side plates.

[0017] Preferably, the second baffle is symmetrically fixedly installed with slot plates on both sides, and a threaded pin is inserted into the inner wall of the slot plate. One end of the threaded pin is fixedly installed on one side of the block, and a nut is threadedly connected to the outer surface of the threaded pin.

[0018] The effect achieved by the above components is as follows: when the threaded pin is inserted into the inner wall of the slot plate and the nut is rotated, one side of the nut presses against the slot plate, and one side of the slot plate abuts against one side of the stop block, thus fixing the second stop plate to the rectangular tube. At the same time, the second stop plate can be easily disassembled, which facilitates the addition or removal of the counterweight body.

[0019] Preferably, a rubber pad is fixedly installed on one side of the nut, the threaded pin is slidably inserted into the inner wall of the rubber pad, and a stop is fixedly installed on one end of the threaded pin.

[0020] The effects achieved by the above components are as follows: by setting the rubber pad, the friction between the nut and the slot plate can be increased, which helps to prevent the nut from loosening. At the same time, by setting the stop block, one end of the threaded pin can be blocked, which helps to prevent the nut from coming off the threaded pin.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, the side plate is moved horizontally by setting a threaded rod to release the restriction of the counterweight body by the side plate, without disassembling the entire counterweight frame. This reduces the number of operation steps and effectively improves the efficiency of adding or removing counterweights. Attached Figure Description

[0029] Example 1, referring to Figures 1-3As shown, this embodiment discloses a counterweight assembly that facilitates the addition and removal of counterweights. It includes a support frame 1, with side plates 3 symmetrically slidably mounted on the support frame 1. A top frame 2 is slidably mounted on one end of each of the two side plates 3. Several counterweight bodies 4 are disposed between the two side plates 3, all placed on top of the support frame 1. A quick-release device 5 is provided between the two side plates 3. The quick-release device 5 includes a rectangular cylinder 51, which is positioned on top of one of the counterweight bodies 4. Rectangular rods 52 are symmetrically slidably mounted on the inner wall of the rectangular cylinder 51, with one end of each rod slidably mounted on the inner wall of the side plate 3. A threaded cylinder 53 is fixedly mounted on one side of the rectangular cylinder 51. Threaded rods 54 are symmetrically threaded onto the inner wall of the threaded cylinder 53, and the outer surface of the threaded rods 54 is rotatably connected via bearings. A screw plate 55 is slidably installed on one side of the side plate 3. The rectangular cylinder 51 is pushed to drive the rectangular rod 52 to slide on the inner wall of the side plate 3 until the bottom of the rectangular cylinder 51 abuts against the top of the counterweight body 4. Then, the two threaded rods 54 are rotated, and the threaded rods 54 extend and retract on the inner wall of the threaded cylinder 53, while driving the side plate 3 to move horizontally until both ends of several counterweights are completely inserted into the inner walls of the two side plates 3, thus completing the assembly of the counterweights. At the same time, when it is necessary to add or remove counterweights, simply rotate the two threaded rods 54 in the opposite direction to make the side plate 3 move away from the counterweights, so that both sides of the counterweights lose their limit. Then push the rectangular cylinder 51 upward to make the top of the counterweights also lose its limit, and then the counterweight body 4 can be added or removed.

[0030] Reference Figures 2-4 As shown, an extension block 56 is fixedly installed at one end of the screw hole plate 55. One side of the extension block 56 abuts against one side of the side plate 3. A bolt 57 is threaded into the inner wall of the extension block 56. By rotating the bolt 57, one end of the bolt 57 abuts against one side of the side plate 3, thus fixing the screw hole plate 55 and the side plate 3. This also helps to fix the rectangular tube 51 and the rectangular plate in the vertical direction, which helps to prevent the rectangular tube 51 from shifting and causing the counterweight body 4 to fall out of the limit of the rectangular tube 51. A rubber strip 58 is bonded to the inner wall of one side of the side plate 3. The bolt 57 is set on one side of the rubber strip 58. By setting the rubber strip 58 to replace one side of the side plate 3 and abut against one end of the bolt 57, the friction between the bolt 57 and the side plate 3 can be increased, thus making the bolt 57 more firmly fixed to the rectangular tube 51.

[0031] Reference Figures 2-4 As shown, an operating block 59 is fixedly installed at one end of the threaded rod 54. The outer surface of the operating block 59 is provided with protrusions. By setting the operating block 59, rotating the operating block 59 can drive the threaded rod 54 to rotate on the inner wall of the threaded cylinder 53. At the same time, the protrusions on the outer surface of the operating block 59 can effectively increase the friction of the outer surface of the operating block 59, and have an anti-slip effect when rotating the operating block 59.

[0032] Reference Figure 3 and Figure 5 As shown, auxiliary components 6 are provided on both sides of the rectangular tube 51. The auxiliary components 6 include a first baffle 61 and a second baffle 62. The first baffle 61 is fixedly installed on one side of the rectangular tube 51, and a locking block 63 is fixedly installed on the other side of the rectangular tube 51. One side of the locking block 63 abuts against one side of the second baffle 62. A slotted plate 64 is symmetrically fixedly installed on both sides of the second baffle 62. A threaded pin 65 is inserted into the inner wall of the slotted plate 64. One end of the threaded pin 65 is fixedly installed on one side of the locking block 63. A nut 66 is threadedly connected to the outer surface of the threaded pin 65. The threaded pin 65 is inserted into the inner wall of the slotted plate 64, and the nut 66 is rotated, so that one side of the nut 66 presses against the slotted plate 64, so that one side of the slotted plate 64 abuts against one side of the baffle 67. This can fix the second baffle 62 to the rectangular tube 51, and at the same time make the second baffle 62 easy to disassemble, thereby facilitating the addition or removal of the counterweight body 4.

[0033] Reference Figure 3 and Figure 5 As shown, slotted plates 64 are symmetrically fixedly installed on both sides of the second baffle 62. Threaded pins 65 are inserted into the inner wall of the slotted plates 64. One end of the threaded pin 65 is fixedly installed on one side of the block 63. A nut 66 is threaded onto the outer surface of the threaded pin 65. The threaded pin 65 is inserted into the inner wall of the slotted plate 64, and the nut 66 is rotated, causing one side of the nut 66 to press against the slotted plate 64, making one side of the slotted plate 64 abut against one side of the block 67. This fixes the second baffle 62 to the rectangular tube 51, and simultaneously... The second baffle 62 can be easily removed, which facilitates the addition or removal of the counterweight body 4; a rubber pad 68 is fixedly installed on one side of the nut 66, and the threaded pin 65 is slidably inserted into the inner wall of the rubber pad 68. A stop block 67 is fixedly installed on one end of the threaded pin 65. By setting the rubber pad 68, the friction between the nut 66 and the slot plate 64 can be increased, which helps to prevent the nut 66 from loosening. At the same time, by setting the stop block 67, one end of the threaded pin 65 can be blocked, which helps to prevent the nut 66 from disengaging from the threaded pin 65.

[0034] Working principle: The rectangular cylinder 51 is pushed, causing the rectangular rod 52 to slide along the inner wall of the side plate 3 until the bottom of the rectangular cylinder 51 abuts against the top of the counterweight body 4. The bolt 57 is then rotated, causing one end of the bolt 57 to abut against the rubber strip 58 on one side of the side plate 3. This fixes the rectangular cylinder 51 and the rectangular plate vertically, preventing the rectangular cylinder 51 from shifting and causing the counterweight body 4 to detach from its limit. Then, the two operating blocks 59 are rotated, causing the threaded rod 54 to rotate. The threaded rod 54 extends and retracts along the inner wall of the threaded cylinder 53, simultaneously moving the side plate 3 horizontally until both ends of several counterweights are completely inserted into the inner walls of the two side plates 3. Finally, the threaded pin is removed. Insert 65 into the inner wall of the slot plate 64 and rotate nut 66 so that one side of nut 66 presses against the slot plate 64, causing one side of the slot plate 64 to abut against one side of stop 67, thus fixing the second stop 62 to the rectangular tube 51, completing the assembly of the counterweight. Similarly, when it is necessary to add or remove counterweight body 4, rotate the operating block 59 in the opposite direction to move the side plate 3 away from the counterweight, so that both sides of the counterweight lose their limit. Then rotate bolt 57 to disengage the extension block 56 from bolt 57, push the rectangular tube 51 upward, so that the top of the counterweight also loses its limit. Finally, rotate nut 66 to disassemble the second stop 62, thus allowing the addition or removal of counterweight body 4.
