Description

Technical Field

[0001] The utility model relates to the field of elevators, in particular to an elevator counterweight device. Background Art

[0002] The counterweight is a component of the elevator traction system. Its function is to reduce the power of the traction motor and the torque on the traction wheel and worm gear. The counterweight device is located in the hoistway and is connected to the car through the traction rope via the traction wheel. During the operation of the elevator, the counterweight device slides on the counterweight guide rail through the counterweight guide shoe to play a balancing role. The counterweight device consists of a counterweight frame and a counterweight iron block. Generally, both ends of the counterweight iron block are clamped on the counterweight frame. In order to prevent the counterweight iron block from jumping, it is necessary to set an anti-jump structure above the counterweight iron block. However, the traditional anti-jump structure of the counterweight iron block is generally fixed to the counterweight frame by welding. If the counterweight iron block needs to be replaced or adjusted, the welding point or the anti-jump structure must be destroyed. This structure leads to increased maintenance time and cost. Therefore, it is necessary to further optimize the structure of the elevator counterweight device. Utility Model Content

[0003] The purpose of the utility model is to overcome the problem that the anti-jump structure and the counterweight frame cannot be disassembled and relatively adjusted in the prior art, which leads to increased maintenance time and cost, and to provide an elevator counterweight device. The anti-jump structure and the counterweight frame of the device are detachably connected, and the position of the anti-jump structure can be relatively adjusted, which is convenient for maintenance or adjustment of the counterweight block.

[0004] In order to achieve the above-mentioned purpose, the utility model provides an elevator counterweight device, wherein an anti-jumping plate is arranged above the counterweight block, and the anti-jumping plate is in an "L" shape. A first long strip-shaped adjustment hole is opened on the vertical portion of the anti-jumping plate along the height direction of the counterweight frame, and a first bolt is inserted into the first adjustment hole. The vertical portion of the anti-jumping plate is connected to the counterweight frame by the cooperation of the first bolt and the first nut, and the horizontal portion of the anti-jumping plate is pressed against the counterweight block. In the above-mentioned technical scheme, the anti-jumping plate is connected to the counterweight frame by bolts. If necessary, the anti-jumping plate can be disassembled to release the pressure on the counterweight block, thereby facilitating the adjustment or replacement of the counterweight block. In addition, the hole for connection on the anti-jumping plate is a strip-shaped hole. After loosening the nut, the relative position of the anti-jumping plate can be adjusted to adapt to changes after maintenance or replacement.

[0005] Preferably, an adjustment plate is provided between the counterweight frame and the anti-jump plate, and the first bolt is passed through the adjustment plate and matched with the first nut after passing through the first adjustment hole;

[0006] The adjustment plate is provided with two second long-shaped adjustment holes along the height direction of the counterweight frame, and the two second adjustment holes are arranged side by side along the width direction of the counterweight frame. The counterweight frame is provided with second bolts corresponding to the second adjustment holes. The second bolts pass through the second adjustment holes and cooperate with the second nuts to fix the adjustment plate on the counterweight frame.

[0007] By adopting the above structure, the position adjustment range of the anti-jump plate can be further improved through the adjustment plate, thereby improving its adaptability.

[0008] Preferably, the length of the first adjustment hole is greater than the length of the second adjustment hole. With this solution, the two adjustment holes have different adjustment ranges, and when adjusting the anti-jump board, a suitable adjustment position can be selected according to the height of the adjustment.

[0009] Preferably, a detent pulley is installed on the top of the counterweight frame, and first protective members are respectively provided on the left and right sides of the detent pulley. A third strip-shaped adjustment hole is provided on the first protective member along the length direction of the counterweight frame, and a third bolt is passed through the counterweight frame corresponding to the third adjustment hole. The third bolt passes through the third adjustment hole and cooperates with the third nut, so that the first protective member is fixed on the counterweight frame. With this structure, the first protective member can play a safety blocking role for the pulling rope wound on the detent pulley to prevent rope skipping. In addition, for safety or maintenance, the third bolt can be loosened to move the first protective member so that there is a larger gap between it and the detent pulley, which is convenient for threading the rope.

[0010] Preferably, the first protective member comprises a baffle, the baffle faces the deflecting pulley, two side edges of the baffle are respectively bent in a direction away from the deflecting pulley to form an adjustment portion, the adjustment portion is provided with the third adjustment hole, and a reinforcing rib is connected between the two adjustment portions;

[0011] The lower edge of the baffle is bent in a direction away from the anti-rope pulley to form an anti-rope skipping portion.

[0012] The above structure facilitates installation and adjustment of the first protective member, and at the same time the strength of the baffle can be improved by reinforcing ribs.

[0013] Preferably, a bracket is installed on the counterweight frame at both sides of the anti-rope pulley, and a fourth long adjustment hole is opened on the bracket along the height direction of the counterweight frame. A second protective member is arranged below the anti-rope pulley, and a fourth bolt is passed through the fourth adjustment hole, and the fourth bolt is threadedly connected with the second protective member after passing through the fourth adjustment hole. With this structure, the second protective member can play a safety protection role for the anti-rope pulley to prevent rope skipping. If necessary, the fourth bolt can be loosened to adjust the distance between the second protective member and the anti-rope pulley to facilitate rope threading.

[0014] Preferably, the bracket is in a "Y" shape, and its two upper arms are fixedly connected to the counterweight frame, and the two ends of the wheel shaft of the anti-rope pulley fall between the two corresponding upper arms of the bracket, and the fourth adjustment hole is provided on the lower arm of the bracket. With this structure, the two upper arms of the bracket can limit the wheel shaft of the anti-rope pulley to prevent the wheel shaft from moving left and right during the lifting process.

[0015] Preferably, the counterweight frame includes two oppositely arranged columns, a crossbeam is connected between the two columns, the cross section of the columns is in a "concave" shape, the two ends of the counterweight block are respectively clamped in the grooves of the corresponding columns, and the two groove walls of the columns are respectively bent in the width direction of the counterweight frame to form a reinforcement part. With this structure, the strength of the column can be effectively improved through the reinforcement part.

[0016] Preferably, a row of connection holes is respectively provided on the two reinforcement parts along the height direction of the column, and the two rows of connection holes respectively correspond to the two second adjustment holes on the adjustment plate, and the two second bolts for fixing the adjustment plate are respectively passed through two of the connection holes at the same height. With this structure, the adjustment plate can be fixed by selecting a suitable mounting hole according to the needs.

[0017] The above technical solution has the following beneficial effects:

[0018] (1) The anti-jump board is detachably connected to the counterweight frame and can be disassembled when necessary. The relative position of the anti-jump board can also be adjusted as needed;

[0019] (2) Protective parts are provided on the left and right sides and the bottom of the anti-rope wheel, which can effectively prevent the anti-rope wheel from skipping the rope;
