Description
Technical field
the utility model relates to a kind of device for preventing elevator from resonating.
Background technology
at present, the towing machine of elevator is generally mounted on the frame base of a channel-section steel or cast iron manufacture, is fixed on frame base with bolt by towing machine, and the bolt of the connection between base and roof beam structure is fixed.But when elevator runs, the vibration of towing machine makes elevator operation more not steady; And due to the difference of the factor such as setting accuracy, story height, the natural frequency of elevator is also different, if the oscillation frequency produced when towing machine runs is just in time equal with elevator natural frequency, then elevator will produce resonance, produces larger noise.Therefore, existing elevator also exists the problem that resonating and noise is larger steadily, does not easily appear in operation.
Utility model content
the purpose of this utility model is, provides a kind of device for preventing elevator from resonating.The utility model can not only improve running stability, can also prevent resonance and reduce noise.
the technical solution of the utility model: a kind of device for preventing elevator from resonating, comprises roof beam structure, be provided with towing machine in the middle part of roof beam structure; Be provided with frame base between towing machine and roof beam structure, the bottom of frame base is provided with some earthquake absorption blocks; The both ends of roof beam structure are all connected with some clump weights by screw rod, and screw tip is connected with hold-down nut, and hold-down nut can compress clump weight; The middle part of described clump weight bottom surface is provided with groove, and the position of clump weight top respective slot is provided with tenon, facilitates the connection between upper and lower two pieces of clump weights and location; The clump weight of tenon arranged on left and right sides is equipped with knock hole, and the front and rear sides of tenon is equipped with handle slot, facilitates the dismounting of clump weight.
in aforesaid a kind of device for preventing elevator from resonating, described clump weight is connected with screw rod by knock hole, and the clump weight quantity being positioned at roof beam structure both ends is identical.
compared with prior art, the utility model provides a kind of device preventing elevator from resonating, and is provided with earthquake absorption block at frame base, carries out damping to towing machine, improves running stability; Screw rod is set at the both ends of roof beam structure to connect clump weight, thus changes the natural frequency of the elevator after towing machine installation, avoid resonance frequency, prevent the generation of resonating, reduce noise, and structure is simple.The upper/lower terminal of clump weight of the present utility model is provided with tenon and groove respectively, coordinates knock hole, screw rod and hold-down nut, clump weight can be facilitated to install accurately and locate, improve structural stability, prevent centre-of gravity shift, guarantee roof beam structure uniform force, improve the life-span of roof beam structure; Clump weight front and rear sides is provided with handle slot, can facilitate the Assembly &Disassembly of clump weight, and convenient adjustment balance weight and natural frequency, prevent resonance.Therefore, the utility model can not only improve running stability, prevents resonance, reduces noise, convenient installs and location, also has that structural stability is good, structure is simple, an advantage of easy to adjust and long service life.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
fig. 2 is the structural representation of clump weight.
being labeled as in accompanying drawing: 1-roof beam structure, 2-towing machine, 3-frame base, 4-earthquake absorption block, 5-screw rod, 6-clump weight, 7-hold-down nut, 61-groove, 62-tenon, 63-knock hole, 64-handle slot.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment.The device resonated for preventing elevator, forms as shown in Figure 1, 2, comprises roof beam structure 1, be provided with towing machine 2 in the middle part of roof beam structure 1; Be provided with frame base 3 between towing machine 2 and roof beam structure 1, the bottom of frame base 3 is provided with some earthquake absorption blocks 4; The both ends of roof beam structure 1 are all connected with some clump weights 6 by screw rod 5, and screw rod 5 top is connected with hold-down nut 7, and hold-down nut 7 can compress clump weight 6; The middle part of described clump weight 6 bottom surface is provided with groove 61, the position of clump weight 6 top respective slot 61 is provided with tenon 62, clump weight 6 can connect the groove 61 of the counterweight 6 being in top by tenon 62, facilitate the connection between upper and lower two pieces of clump weights 6 and location; The clump weight 6 of tenon 62 arranged on left and right sides is equipped with knock hole 63, and the front and rear sides of tenon 62 is equipped with handle slot 64, facilitates the dismounting of clump weight 6.
described clump weight 3 is connected with screw rod 5 by knock hole 6, and clump weight 3 quantity being positioned at roof beam structure 1 both ends is identical.
during use, start towing machine 2 and debug, earthquake absorption block 4 can carry out damping to towing machine 2, improves the operation stability of elevator; If resonating and producing noise appears in elevator, then by handle slot 64, two pieces of clump weights 6 are respectively installed on the both ends of roof beam structure 1, positioned by the knock hole 63 on clump weight 6 and screw rod 5 pairs of clump weights 6, then screw hold-down nut 7, improve connective stability.If also there is resonance, then unscrew hold-down nut 7, again on screw rod 5, clump weight 6 is installed, the groove 61 of clump weight 6 bottom surface is connected with the tenon 62 at mounted clump weight 6 top, improve setting accuracy; Until the natural frequency after changing avoids resonance frequency, resonance disappears, and stops adding clump weight 6.
