Description

Technical Field

[0001] This utility model relates to the field of elevators, specifically to an elevator car counterweight frame that is easy to inspect and maintain. Background Technology

[0002] The counterweight frame of an elevator car is a device that fixes the counterweight blocks, used to reduce the power of the traction motor and improve the efficiency of the elevator car's vertical movement. The structure of the counterweight frame affects the stability of the elevator operation. Existing counterweight frames are basically assembled from profiles or plates. The counterweight frame includes the counterweight frame body and the rope pulley assembly. The rope pulley is fixed by the upper beam and clamping plate on the counterweight frame to fix the rope pulley shaft. The sides of the rope pulley need to be protected by rope guards to shield the wire rope, and the top of the rope pulley is protected from dust by a dust cover installed on the upper beam plate.

[0003] In the existing technology, the dust cover is fixedly installed on the top of the upper beam plate with bolts, and the clamping plate and rope guard plate are fixedly connected to the upper beam plate with bolts. When the rope wheel structure of the heavy frame is inspected, the dust cover, rope guard plate and clamping plate on one side need to be removed one by one. After the clamping plate on one side is removed, the rope wheel shaft supporting the rope wheel loses stable support, and the rope wheel will fall off. After the inspection, they need to be installed one by one. The disassembly and assembly process is very troublesome and the inspection efficiency is low. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an elevator car counterweight frame that is easy to maintain. It can solve the problem that when the rope wheel structure of the existing counterweight frame is maintained, the dust cover, rope guard plate and the clamp plate on one side need to be removed one by one. The disassembly and assembly process is very troublesome and the maintenance efficiency is low.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: it includes a counterweight frame upper beam, a counterweight frame side upright beam, a counterweight frame lower beam, and a rope wheel. The counterweight frame upper beam is fixedly installed on the top of the counterweight frame side upright beam by bolts, and the counterweight frame lower beam is fixedly installed on the bottom of the counterweight frame side upright beam by bolts. The counterweight frame upper beam includes two oppositely arranged upper beam plates, the rope wheel is installed between the two upper beam plates, and a clamping plate is connected to the outer side of the two upper beam plates respectively. The clamping plate includes an upper plate and a lower plate. The upper plate is fixed to the upper beam plate, and the support shaft of the rope wheel is supported on the upper plate. The upper plate and the lower plate are fixedly connected by bolts.

[0006] The tops of the two upper beams are movably fitted with dust covers;

[0007] The rope pulley is provided with rope-blocking plates on both sides. The rope-blocking plates are rotatably disposed between the two upper beam plates. The rope-blocking plates have a U-shaped structure and are mounted on the two upper beam plates via a rotating shaft. The rope-blocking plates are fixed to the two upper beam plates by bolts.

[0008] The lower plates of the card plate are connected by round steel.

[0009] Furthermore, the upper plate has an extension section at the bottom middle part, the thickness of the extension section being less than the thickness of the upper plate, and the lower plate has a slot at the top middle part, the extension section being inserted into the slot of the lower plate.

[0010] Furthermore, the dust cover has a U-shaped structure, with movable plates on the inner sides of the two side plates of the dust cover and movable grooves on the outer sides of the upper beam plate. The movable plates are located in the movable grooves and move horizontally along the movable grooves. The side plates of the dust cover are locked to the upper beam plate by bolts.

[0011] Furthermore, each side of the rope-blocking plate is provided with a screw hole, and the rope-blocking plate is fixed to each of the two upper beam plates by a bolt, and the bolt fixing positions on the two upper beam plates are staggered.

[0012] Furthermore, two round steel bars are provided, with the two round steel bars respectively located on both sides below the rope wheel.

[0013] With the above structure, the advantages of this utility model are: the dust cover can be movably installed on the top of the upper beam plate. During maintenance, the dust cover can be slid to the side, no longer blocking the top of the rope wheel, and there is no need to disassemble the dust cover, making the operation more convenient.

[0014] The card plate is composed of two parts: an upper plate and a lower plate. During maintenance, the lower plate can be removed to provide maintenance space without removing the upper plate. The support shaft of the rope pulley can still be supported by the upper plate, and the rope pulley structure does not need to be disassembled, making maintenance more convenient.

[0015] The rope guard plate and the upper beam plate are connected by a rotating shaft. During maintenance, the rope guard plate does not need to be disassembled. After the rope guard plate is rotated, it is temporarily fixed by bolts, which leaves room for operation and maintenance. The disassembly and assembly process is simple and the maintenance efficiency is improved. Attached Figure Description

The bottom of the counterweight frame side upright beam 2 is fixedly installed with the counterweight frame lower beam 3 by bolts. The counterweight frame upper beam 1 includes two opposing upper beam plates 11. The rope pulley 4 is installed between the two upper beam plates 11. The outer sides of the two upper beam plates 11 are respectively connected to clamping plates 6. The clamping plates 6 include an upper plate 61 and a lower plate 62. The upper plate 61 is fixed on the upper beam plate 11. The support shaft 41 of the rope pulley 4 is supported on the upper plate 61. Figure 4 As shown, the upper plate 61 has an extension section 611 at the bottom middle part, and the thickness of the extension section 611 is less than the thickness of the upper plate 61. The lower plate 62 has a slot at the top middle part (not shown in the figure). The extension section 611 is inserted into the slot of the lower plate 62 and fixed by bolts. The upper plate 61 and the lower plate 62 are detachable splicing structures. During maintenance, the lower plate 62 can be removed, while the connection between the upper plate 61 and the upper beam plate 11 is maintained. The support shaft 41 of the rope wheel 4 can still be supported, and the rope wheel 4 does not need to be disassembled and reinstalled.
