Description

Technical Field

[0001] The utility model relates to a single-door counterweight, in particular to an enhanced single-door counterweight applied to the field of mechanical accessories. Background Art

[0002] The feed door of a construction hoist is usually designed as a single door. When the single door is opened, the counterweight directly associated with the single door will naturally move downward under the influence of gravity. This movement mechanism helps to make the door opening operation smoother and more labor-saving. Conversely, when the single door needs to be closed, the counterweight will be lifted upward by the chain connected to it, making the door closing process equally smooth.

[0003] The specification of Chinese patent CN207312887U discloses a hoist cage, including a cage body, a first side door and a second side door, the cage body includes a hollow rectangular parallelepiped frame structure with two side openings in the length direction, the first side door includes a first door frame and a single door panel, the single door panel is arranged in the first door frame, the second side door includes a second door frame and a double door panel, and the first door frame and the second door frame can be installed interchangeably on the two side openings of the cage body, the cage body is provided with a transmission guide rail and a counterweight slide on the side wall in the width direction, and the counterweight slide can be detachably installed on the side of the first door frame. The utility model aims to solve the problem that the left and right cages of the existing construction elevator cannot be interchanged, which easily leads to installation errors.

[0004] During actual use, the single-door counterweight design of traditional construction elevators has a large gap between the counterweight and the inner side of the counterweight slideway groove, which is easy to collide and vibrate during sliding, affecting the life of the equipment. The single fixed pulley design causes the chain to be eccentric when pulling the single-row door, increasing the friction resistance between the single-door pulley and the door frame, which not only makes it difficult to open the door but also shortens the life of the pulley. When dust or foreign objects are stuck between the counterweight and the slideway, the counterweight may get stuck due to increased friction, and even cause jamming between the connecting chain and the counterweight. This situation not only affects the normal operation of the elevator, but may also cause damage to the equipment, increasing maintenance costs and time. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that the single-door counterweight design of the traditional construction elevator has a large gap between the counterweight and the inner side of the counterweight slideway groove, which is easy to collide and vibrate during sliding, affecting the life of the equipment. The single fixed pulley design causes the chain to be eccentric when pulling the single-row door, increasing the friction resistance between the single-door pulley and the door frame, which not only makes it difficult to open the door but also shortens the life of the pulley. When dust or foreign objects are stuck between the counterweight and the slide, the counterweight may get stuck due to increased friction, and even cause jamming between the connecting chain and the counterweight. This situation not only affects the normal operation of the elevator, but may also cause damage to the equipment, increasing maintenance costs and time.

[0006] To solve the above problems, the utility model provides an enhanced single-door counterweight, including a counterweight body, a plurality of single-door counterweight pulleys are distributed in a rectangular shape on the outer side of the counterweight body, a sliding rope body is slidably connected between two single-door counterweight pulleys corresponding to the upper and lower sides, and an auxiliary maintenance component is arranged at the upper end of the counterweight body, the auxiliary maintenance component includes a hollow liquid storage frame fixedly connected to the upper end of the counterweight body, and the left and right ends of the hollow liquid storage frame are symmetrically and rotatably connected to the liquid outlet pipe strip, a first driving gear component is installed at one end of the single-door counterweight pulley away from the counterweight body, an extended rotating rod is symmetrically arranged at the left and right ends of the hollow liquid storage frame, the outer end of the extended rotating rod is fixedly connected to a second linkage gear component, and the second linkage gear component is meshed with the first driving gear component, the outer end of the extended rotating rod is fixedly connected to a rotating inner ring, the rotating inner ring is located between the second linkage gear component and the hollow liquid storage frame, the outer end of the rotating inner ring is fixedly connected to a plurality of spring components, and the end of the spring component away from the rotating inner ring is fixedly connected to a brush layer oil wiping block.

[0007] In the above-mentioned enhanced single-door counterweight, the counterweight in this solution uses its own gravity to keep the sliding rope bodies at both ends in a vertical state, thereby reducing the phenomenon of jamming between the sliding rope body and the counterweight.

[0008] As a further improvement of the present application, a suspension point block is fixedly connected to the upper end of the counterweight body, and the second linkage gear member is located directly above the first driving gear member.

[0009] As a further improvement of the present application, a hexagonal bolt is provided at the inner end of the single-door counterweight pulley, and the hexagonal bolt extends into the counterweight body.

[0010] As a further improvement of the present application, a washer layer is fixedly connected to the outer end of the hexagonal bolt, and a plurality of thread adhesives are filled between the hexagonal bolt and the counterweight pulley sleeve.

[0011] As another improvement of the present application, the bristle layer oil wiping block contacts the outer side walls of the single-door counterweight pulley and the sliding rope body, and the liquid outlet pipe strip is located between the corresponding rotating inner ring and the single-door counterweight pulley.

[0012] As another improved supplement of the present application, one end of the liquid outlet pipe strip close to the single-door counterweight pulley is fixedly connected to a one-way oil outlet valve body, and the lower inner wall of the hollow liquid storage frame is fixedly connected to an arc-shaped convex surface.

[0013] As another improved supplement of the present application, a heating wire layer is fixedly connected to the upper side of the inner end of the arc-shaped protruding surface, and the inner end of the hollow liquid storage frame is filled with lubricating oil.

[0014] In summary, the counterweight body in this scheme uses its own gravity to keep the sliding rope bodies at both ends in a vertical state, reducing the phenomenon of jamming between the sliding rope body and the counterweight body. At the same time, by setting up auxiliary maintenance components, the sliding rope body in the counterweight system can be effectively lubricated to reduce the friction between the sliding rope body and the single-door counterweight pulley, avoiding component damage caused by excessive friction, thereby significantly extending the service life of the counterweight system, reducing the configuration of the gantry crane traction system under the same force conditions, increasing the service life of the gantry crane motor system, ensuring the stability of equipment operation, and reducing the operating noise of the construction elevator.

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-7 An enhanced single-door counterweight is shown, comprising a counterweight body 1, a plurality of single-door counterweight pulleys 3 are distributed in a rectangular shape on the outer side of the counterweight body 1, a sliding rope body 16 is slidably connected between two corresponding single-door counterweight pulleys 3, an auxiliary maintenance component is arranged at the upper end of the counterweight body 1, the auxiliary maintenance component comprises a liquid storage hollow frame 7 fixedly connected to the upper end of the counterweight body 1, the left and right ends of the liquid storage hollow frame 7 are symmetrically rotatably connected to the liquid outlet pipe strip 11, and a first driving gear member 9 is installed at one end of the single-door counterweight pulley 3 away from the counterweight body 1, The left and right ends of the liquid storage hollow frame 7 are symmetrically provided with extended rotating rods 8, the outer end of the extended rotating rod 8 is fixedly connected with the second linkage gear member 10, and the second linkage gear member 10 is meshingly connected with the first driving gear member 9, the outer end of the extended rotating rod 8 is fixedly connected with a rotating inner ring 12, the rotating inner ring 12 is located between the second linkage gear member 10 and the liquid storage hollow frame 7, the outer end of the rotating inner ring 12 is fixedly connected with a plurality of spring members 13, and the end of the spring member 13 away from the rotating inner ring 12 is fixedly connected with a brush layer oil wiping block 14.

[0027] Figure 1-7 It is shown that the upper end of the counterweight body 1 is fixedly connected to the hanging point block 2, the second linkage gear member 10 is located directly above the first driving gear member 9, the inner end of the single-door counterweight pulley 3 is provided with a hexagonal bolt member 6, the hexagonal bolt member 6 extends into the counterweight body 1, the outer end of the hexagonal bolt member 6 is fixedly connected to the gasket layer 4, and a number of threaded glues are filled between the hexagonal bolt member 6 and the counterweight pulley sleeve 5. The brush layer oil block 14 is in contact with the outer side walls of the single-door counterweight pulley 3 and the sliding rope body 16. The liquid outlet pipe strip 11 is located between the corresponding rotating inner ring 12 and the single-door counterweight pulley 3. The end of the liquid outlet pipe strip 11 close to the single-door counterweight pulley 3 is fixedly connected to the one-way oil outlet valve body 15, and the inner end of the liquid storage hollow frame 7 is filled with lubricating oil.

[0028] Figure 1-7It is shown that the counterweight body 1 in this scheme keeps the sliding rope bodies 16 at both ends in a vertical state through its own gravity, reducing the phenomenon of jamming between the sliding rope body 16 and the counterweight body 1, reducing the configuration of the door machine dragging system under the same force conditions, improving the service life of the door machine motor system, ensuring the stability of equipment operation, and reducing the operating noise of the construction elevator.
