Description

Technical Field

[0001] This utility model relates to the field of motor parts manufacturing and processing technology, and in particular to a cover plate on the top of a traction machine. Background Technology

[0002] The elevator traction machine is the power unit of the elevator, also known as the elevator main unit. Its function is to deliver and transmit power to make the elevator run. It consists of a motor, brake, coupling, gearbox, traction sheave, frame, guide wheels, and an auxiliary handwheel. The guide wheels are generally mounted on the frame or the load-bearing beam under the frame. The handwheel is sometimes fixed to the motor shaft, and sometimes it is hung on a nearby wall and then put on the motor shaft when in use.

[0003] A wire rope or steel belt is suspended on a traction sheave. The surface of the traction sheave is machined with rope grooves. The wire rope or steel belt fits into the rope grooves. One end is connected to the car and the other end is connected to the counterweight device. The motor (permanent magnet synchronous motor or AC asynchronous motor) transmits power to the traction sheave through a coupling or gearbox (for geared models), causing it to rotate. Through friction, the car and counterweight move in opposite directions.

[0004] Traction machines are installed in equipment rooms and are directly exposed to the air, making them susceptible to damage from falling objects such as stones and concrete debris. Utility Model Content

[0005] The purpose of this invention is to provide a cover plate on the top of a traction machine, which has the advantage of preventing the traction machine from being damaged by external objects.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A cover plate on the top of a traction machine includes a front cover plate and a rear cover plate side by side. The surfaces of the front and rear cover plates are respectively fixedly connected with reinforcing ribs. The front and rear ends of the front and rear cover plates are respectively fixedly connected with side beams. A merging plate is fixedly connected between two side beams on different sides of the same end. Right-angled notches are respectively opened at the corners of the edges where the front and rear cover plates intersect. When the front and rear cover plates are spliced, the two right-angled notches on the same end form a U-shaped notch. The merging plate passes through the side above the U-shaped notch on the same end of the cover plate. The merging plate and the two side beams connected to it have opposite through holes.

[0008] Using the above technical solution, the shield is placed above the traction machine. The shield is fixed by connecting the external brackets on the embedded parts fixed in the wall of the traction machine chamber to the merging plate. The shield can block objects falling from the top of the traction machine, preventing them from hitting the traction machine and causing damage. The reinforcing ribs can increase the load-bearing capacity of the shield. Bolts are used to pass through the through holes that are aligned with the side beams of the merging plate, and nuts are tightened on the bolts to fix the merging plate to the side beams. The shield is placed above the traction machine, and the external brackets on the embedded parts fixed in the wall pass through the U-shaped notches at both ends of the shield to connect the external brackets to the merging plate, thus fixing the shield.

[0009] Preferably, the reinforcing ribs on the front cover plate and the rear cover plate are arranged in a rectangular shape.

[0010] By adopting the above technical solution, the orderly and regular arrangement of the reinforcing ribs can increase the aesthetics and load-bearing capacity of the shield.

[0011] Preferably, the side beam includes a connecting piece one and a connecting piece two, which are integrally formed together and perpendicular to each other. The connecting piece two is fixedly connected to the front and rear cover plates. The edges of the connecting pieces one of the two side beams located at the same end and on different cover plates are in contact with each other, and the merging plate is connected to the two connecting pieces one that are in contact with each other.

[0012] Using the above technical solution, the connecting piece 2 of each side beam contacts the front cover plate or the rear cover plate. By passing the rivet nut through the connecting piece 2 and the front or rear cover plate in contact with it, the side beam is fixed to the cover plate.

[0013] Preferably, the merging plate has two waist-shaped grooves arranged in a figure-eight shape, and the two contacting connecting pieces each have a waist-shaped groove opposite to the first waist-shaped groove.

[0014] Using the above technical solution, the two waist-shaped grooves of the merging plate are respectively aligned with the waist-shaped grooves of the two connecting pieces, so that the external brackets on the embedded parts welded in the wall pass through the U-shaped notches on both sides of the cover plate. The external brackets are provided with waist-shaped grooves that match the two waist-shaped grooves of the merging plate. Bolts are used to pass through each set of opposite waist-shaped grooves, and nuts are tightened on the bolts to fix the cover plate. By arranging the two waist-shaped grooves into a figure-eight shape, the bolts exert lateral and vertical forces on the two waist-shaped grooves of the merging plate, the crossbeam and the external bracket, avoiding relative movement between the three, increasing the connection effect between the merging plate, the side beam and the frame, and making the structure of the cover plate more stable.

[0015] Preferably, the reinforcing rib is U-shaped, with the opening of the U-shaped reinforcing rib facing downwards, and the bottom surfaces on both sides of the opening are fixedly connected to the front and rear cover plates.

[0016] By adopting the above technical solution, the Z-shaped reinforcing ribs will not reduce their stress-bearing effect while reducing their material usage.

[0017] In summary, this utility model has good protective properties, good stress resistance, and is easy to install. Attached Figure Description

[0028] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0029] See Figures 1 to 5A cover plate for the top of a traction machine includes a front cover plate 1 and a rear cover plate 2 side by side. Right-angled notches 5 are respectively provided at the two corners of the intersection of the front cover plate 1 and the rear cover plate 2. When the front cover plate 1 and the rear cover plate 2 are spliced, the two right-angled notches 5 at the same end form a U-shaped notch. Z-shaped reinforcing ribs 3 are fixedly connected to the surfaces of the front and rear cover plates (1, 2). The openings of the Z-shaped reinforcing ribs 3 face downwards, and the bottom surfaces on both sides of the openings contact the front cover plate 1 and the rear cover plate 2. By passing rivet nuts through the bottom surfaces on both sides of the openings of the reinforcing ribs 3 and the front cover plate 1 and the rear cover plate 2, the reinforcing ribs 3 can be fixed to the front cover plate 1 and the rear cover plate 2. The Z-shaped design does not reduce the load-bearing capacity of the reinforcing ribs 3 while reducing the amount of material used. Furthermore, the reinforcing ribs 3 on each cover plate are arranged in a rectangle, which increases the aesthetics and load-bearing capacity of the cover plate.

[0030] See Figure 1 , Figures 6 to 8 Each cover plate has side beams fixedly connected to its front and rear ends. The side beams include connecting piece 6 and connecting piece 7, which are integrally formed together and perpendicular to each other. The connecting piece 7 of each side beam is fixedly connected to the front and rear cover plates (1, 2) by rivet nuts. The edges of the connecting pieces 6 of the two side beams located at the same end and on different cover plates are in contact with each other. The cover plate also includes a merging plate 4, which is connected to the two contacting connecting pieces 6. The merging plate 4 passes through the side above the U-shaped notch located at the same end of the cover plate. The merging plate 4 has two waist-shaped grooves 8 arranged in a figure-eight shape. The two contacting connecting pieces 6 each have waist-shaped grooves 9 opposite to the waist-shaped grooves 8. The merging plate 4 and the connecting pieces 6 of the two side beams connected to it have opposite through holes 10.

[0031] Working principle: Bolts are used to pass through the through holes 10 of the merging plate 4, which are aligned with the side beam, and then nuts are tightened on the bolts to fix the merging plate 4 to the side beam. Then, the shield is placed above the traction machine, and the external brackets fixed to the embedded parts in the wall pass through the U-shaped notches on both sides of the shield. The external brackets are L-shaped and are fixed to the embedded parts in the wall by welding or bolts and nuts. The two sides of the external brackets are respectively provided with waist-shaped grooves 3 that match the two waist-shaped grooves 9 of the merging plate 4. Bolts are then used to pass through each set of corresponding waist-shaped grooves 8, 9, and 3, and nuts are tightened on the bolts to fix the shield. By arranging the two waist-shaped grooves 8 into a figure-eight shape, the connection effect between the merging plate 4 and the side beam is increased, making the shield structure more stable. The shield can block objects falling from the top of the traction machine, preventing objects from hitting the traction machine and causing damage. The reinforcing ribs 3 can increase the stress-bearing effect of the shield.
