Description

Technical Field

[0001] The utility model relates to the technical field of elevator equipment, in particular to a spliced ​​elevator counterweight. Background Art

[0002] The counterweight of the elevator plays a very important role in the balance and stability of the elevator operation. The counterweight and the car are fixed at both ends of the wire rope and hung on the sheave of the elevator motor, which can effectively balance the weight of the car, ensure the smooth operation of the elevator, and reduce the power consumption of the elevator motor.

[0003] The patent specification with announcement number CN209322272U discloses a spliced ​​combined elevator counterweight block, which is composed of 4 standard counterweight blocks and a dovetail block. The groove of the isosceles trapezoidal cross-section of one standard counterweight block is neatly opposite to the groove of the isosceles trapezoidal cross-section of another standard counterweight block, forming a layer of standard counterweight blocks spliced ​​by two standard counterweight blocks. The two layers of standard counterweight blocks formed by two standard counterweight blocks are neatly stacked up in turn, and the dovetail block is inserted into the bow-shaped groove formed by the two standard counterweight blocks, thus forming an overall connection between the two layers of counterweight blocks of the two standard counterweight blocks. Due to the characteristics of the dovetail groove, the four standard counterweight blocks are combined together and are not prone to movement.

[0004] However, in the implementation of relevant technologies, it was found that the above-designed spliced ​​combined elevator counterweight block has the following problems: in the prior art, multiple counterweight blocks and dovetail blocks are assembled so that they can be freely assembled and carried, but in actual use, the counterweight blocks need to be formed into a whole and used in conjunction with the elevator, resulting in the lack of a unified supporting structure during use. The relative counterweight blocks will become loose up and down, causing the counterweight blocks to become loose or even fall. In view of this, a spliced ​​elevator counterweight block is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a spliced ​​elevator counterweight.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a spliced ​​elevator counterweight block, comprising a base frame, a device shell is fixed to the bottom end of the base frame, a counterweight block is arranged above the base frame, and a stabilizing mechanism is arranged inside the device shell;

[0007] The stabilizing mechanism includes a dual-output motor, which is embedded in the equipment shell, and the power output ends of the dual-output motors are connected to a first worm, one end of the outer wall of the two first worms is connected to a first worm wheel, and a second worm is passed through the first worm wheel, both ends of the outer wall of the second worm are connected to a second worm wheel, and a threaded rod is passed through the second worm wheel, and the outer wall of the threaded rod passes through one end of the counterweight block and is slidably connected to a sleeve, and a pressing plate is sleeved on the outer wall of the sleeve, and each counterweight block is provided with a reserved hole corresponding to the threaded rod to limit the position and avoid sliding, and the frame is supported to prevent the counterweight block from being unstable and falling during later hoisting or work inside the elevator shaft.

[0008] As a further description of the above technical solution: the sleeve is threadedly connected to the threaded rod, and the sleeve is fixedly connected to the pressing plate. After placing the corresponding number of counterweights according to the elevator requirements, the sleeve is sleeved on the top of the threaded rod, and the threaded rod is rotated and threadedly connected to each other. The rotation of the threaded rod allows the sleeve to slide downward along the threaded rod under the limit of the pressing plate to clamp and fix the counterweight to prevent loosening.

[0009] As a further description of the above technical solution: a limiting hole is opened at the top of the counterweight block, and a supporting block passes through the inside of the limiting hole, and the supporting blocks are fixed at the bottom of the counterweight blocks. When stacked on each other, the supporting blocks enter the limiting holes of the next group of counterweight blocks, which serves to further limit the position and avoid sliding and causing the counterweight blocks to loosen and shake.

[0010] As a further description of the above technical solution: a limiting mechanism is provided on one side of the counterweight block at the top of the base frame, and the limiting mechanism includes a limiting plate, and the limiting plate is fixed on one side of the counterweight block of the base frame, and a damping spring is embedded in the limiting plate, and one end of the damping spring passing through the limiting plate is connected to a fitting plate, and the counterweight block is limited and supported from the outside through the limiting plate, so that the counterweight block is located within the range of the base frame, avoiding sliding and loosening during work, thereby improving safety.

[0011] As a further description of the above technical solution: the limiting mechanism also includes a connecting hole, which is opened on the inner wall of the counterweight block, and a connecting column is passed through the inside of the connecting hole. The two counterweight blocks are fixedly connected through the connecting hole and the connecting column, which has an assembly effect, making the counterweight block lighter and easier to transport and assemble.

[0012] As a further description of the above technical solution: the limiting mechanism also includes a slot, which is opened on the outer wall of one counterweight block, and a dovetail block is fixed at the position of the slot on the outer wall of the other counterweight block corresponding to the dovetail block, so that the two counterweight blocks are engaged with each other through the dovetail block and the slot, thereby improving the stability of the counterweight blocks after assembly.

[0013] As a further description of the above technical solution: the bonding plate forms an elastic structure between the damping spring and the limit plate, and the bonding plate is tightly fitted with the counterweight block. The damping spring elastically pushes the bonding plate to avoid shaking when the rope in the elevator pulls the limit plate to work, causing the counterweight block to hit the limit plate and cause damage or noise.

[0014] The utility model has the following beneficial effects:

[0015] The utility model designs a spliced ​​elevator counterweight block, manually supports a pressing plate, and allows a sleeve to be sleeved above a threaded rod, then starts a dual-output motor to drive a first worm, pushes the first worm wheel to drive a second worm, and thus allows the second worm wheel to drive the threaded rod to rotate, the sleeve and the pressing plate slide toward the counterweight block and press the counterweight block to avoid loosening, limits the counterweight block through the threaded rod, and cooperates with limiting holes and supporting blocks to limit each other when stacking to avoid sliding, and is stacked on a base frame to avoid loosening or even dispersion when working in the elevator shaft.

[0016] The utility model designs a spliced ​​elevator counterweight block, which is limited from the outside by a limiting plate on the base frame to prevent the counterweight block from loosening and to provide protection, and allows two counterweight blocks to be assembled through threaded connection of connecting columns and connecting holes, so that the counterweight blocks can be lightweight and miniaturized, and are easy to assemble and transport. At the same time, the two counterweight blocks are engaged with each other through dovetail clamps and clamping grooves to improve stability after assembly. BRIEF DESCRIPTION OF THE DRAWINGS

A threaded rod 406 passes through the inside of the second worm wheel 405. The threaded rod 406 passes through the outer wall of one end of the counterweight block 3 and is slidably connected with a sleeve 407. The outer wall of the sleeve 407 is sleeved with a pressing plate 408. Each counterweight block 3 is provided with a reserved hole corresponding to the threaded rod 406, so as to limit the position and avoid sliding, and support it through the base frame 1 to prevent the counterweight block 3 from becoming unstable and falling during hoisting or work inside the elevator shaft at a later time.

[0026] As a further implementation scheme of the above technical scheme: the sleeve 407 is threadedly connected to the threaded rod 406, and the sleeve 407 is fixedly connected to the pressing plate 408. After placing the corresponding number of counterweights 3 according to the elevator requirements, the sleeve 407 is sleeved on the top of the threaded rod 406, and the threaded rod 406 is rotated to thread them together. The rotation of the threaded rod 406 allows the sleeve 407 to slide downward along the threaded rod 406 under the limit of the pressing plate 408 to clamp and fix the counterweight 3 to prevent it from loosening.

[0027] As a further implementation scheme of the above technical scheme: a limiting hole 5 is opened at the top of the counterweight block 3, and a supporting block 6 is passed through the inside of the limiting hole 5.

Through the same dual-output motor 401, multiple motor groups are prevented from causing errors in the sleeve 407 and tilting the pressing plate 408. Through the cooperation of the limiting hole 5 and the supporting block 6, sliding and loosening between the stacked counterweights 3 are prevented.

A connecting column 704 passes through the inside of the connecting hole 705. The two counterweight blocks 3 are fixedly connected through the connecting hole 705 and the connecting column 704, which has an assembly effect, making the counterweight block 3 lighter and easier to transport and assemble.

[0031] As a further implementation scheme of the above technical scheme: the limiting mechanism 7 also includes a slot 707, which is opened on the outer wall of one counterweight block 3, and a dovetail block 706 is fixed on the outer wall of the other counterweight block 3 at a position corresponding to the slot 707. The dovetail block 706 and the slot 707 allow the two counterweight blocks 3 to engage with each other, thereby improving the stability of the counterweight blocks 3 after assembly.

[0032] As a further implementation plan of the above technical solution: the bonding plate 702 forms an elastic structure with the limit plate 701 through the damping spring 703, the bonding plate 702 is tightly fitted with the counterweight 3, and the bonding plate 702 is elastically pushed by the damping spring 703 to avoid shaking when the rope in the elevator pulls the limit plate 701 to work, causing the counterweight 3 to hit the limit plate 701 and cause damage or noise.
