Description

Technical Field

[0001] This utility model belongs to the field of counterweight frame technology, specifically relating to a split-type counterweight frame. Background Technology

[0002] Chinese patent CN222743849U discloses a high-strength, vibration-damping elevator counterweight frame, relating to the field of elevator counterweight technology. The frame includes a counterweight frame with a mounting bracket at its upper end, a traction disc at the upper end of the mounting bracket, multiple sets of pressure rods on the inner side of the counterweight frame, and limit nuts on the sides of each set of pressure rods located on the upper outer surface of the counterweight frame. A pressure plate is located at the lower end of each set of pressure rods. This high-strength, vibration-damping elevator counterweight frame, by using pressure rods and pressure plates, can compress the concrete counterweight blocks. The limit nuts prevent the pressure plates from easily loosening. This method of compressing the concrete counterweight blocks is not only simple and convenient to operate, but also, by using multiple sets of pressure rods, prevents the compression effect from being reduced due to the loosening of a single pressure rod, reducing vibration and noise caused by collisions between the concrete counterweight blocks and improving service life.

[0003] However, in the existing technology, the existing counterweight frame is usually a single unit. When used in different environments, different numbers of counterweight bars are required to achieve different counterweights. When the counterweight reaches the limit and more counterweight is needed, the counterweight frame needs to be replaced, which is complicated and costly. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a split counterweight frame to solve the problems mentioned in the background art.

[0005] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A split-type counterweight frame includes an upper counterweight assembly and a lower counterweight assembly. The lower part of the upper counterweight assembly and the upper part of the lower counterweight assembly are detachably connected by channel steel. Both sides of the upper and lower counterweight assemblies are straight beams, and counterweight bars are located between the two straight beams. A rectangular slot is opened on one side of the upper part of each straight beam. The rectangular slot is used to allow the counterweight bars to enter between the two straight beams from one side of the straight beam. The straight beams are provided with connecting holes at the upper and lower parts of the rectangular slots. The connecting holes are used to connect slot baffles. The upper part of the upper counterweight assembly is bolted to an upper beam, and the lower counterweight assembly is bolted to a lower beam.

[0007] Further specified, mounting holes are provided at the upper and lower positions of the middle of the straight beams, and abutment members are connected inside the straight beams on the left and right sides.

[0008] Further specified, the number of channel steels is two, the openings of the two channel steels face the upper and lower sides respectively, the mating surfaces of the two channel steels are detachably connected by bolts, and the end of the straight beam is located at the edge of the channel steel groove and is detachably connected to the channel steel by bolts.

[0009] Further specified, the abutment is U-shaped, located inside the straight beam, and its two sides are connected to the mounting holes of the straight beam by bolts. A connecting hole is opened in the middle plane of the abutment, and an adjusting screw is connected in the connecting hole. Nuts are threaded on the upper and lower sides of the adjusting screw.

[0010] Furthermore, both the upper counterweight assembly and the lower counterweight assembly are connected to a bottom shell, which is snapped into the slot of the straight beam.

[0011] Furthermore, a traction member is connected to the middle of the upper beam.

[0012] Furthermore, a buffer seat is connected to the middle of the lower beam.

[0013] Further specified, the upper part of the upper counterweight assembly and the lower part of the lower counterweight assembly are connected by limiting sliders.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This utility model is ingeniously designed. By rationally arranging the positions of the straight beams and channel steel, when the weight of the counterweight reaches the limit of the straight beam, the weight of the counterweight can be increased by adding more straight beams without having to replace them with longer ones, thus making reasonable use of space.

[0016] This utility model has a reasonable design. By setting a rectangular slot at the top of the straight beam, the counterweight can be placed after the baffle is removed, thereby changing the counterweight of the device. When this opening is not set, the counterweight can be placed at an angle so that the end of the counterweight can enter the straight beam. However, this can only be achieved if there is a certain space inside the straight beam, which is complicated to operate. Attached Figure Description

[0029] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains; the terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0031] like Figure 1-7As shown, a split counterweight frame includes an upper counterweight assembly 1 and a lower counterweight assembly 2. The lower part of the upper counterweight assembly 1 and the upper part of the lower counterweight assembly 2 are detachably connected by a channel steel 3. Both sides of the upper counterweight assembly 1 and the lower counterweight assembly 2 are straight beams 4. The counterweight bar 5 is located between the two straight beams 4. A rectangular slot 41 is opened on one side of the upper part of each straight beam 4. The rectangular slot 41 is used to allow the counterweight bar to enter between the two straight beams 4 from one side of the straight beam 4. The straight beam 4 is provided with connecting holes at the upper and lower parts of the rectangular slot 41. The connecting holes are used to connect the slot baffle 42. The upper part of the upper counterweight assembly 1 is connected to the upper beam 11 by bolts, and the lower counterweight assembly 2 is connected to the lower beam 21 by bolts.

[0032] In this embodiment, the upper counterweight assembly 1 and the lower counterweight assembly 2 are connected by a channel steel 3. The connection between the upper counterweight assembly 1 and the lower counterweight assembly 2 is achieved by making reasonable use of the channel steel 3. A rectangular slot is opened on one side of the straight beam 4. The width of the slot is slightly larger than the width of the counterweight bar, so that the counterweight bar can directly enter the straight beam 4 from the rectangular slot. The baffle 42 is set so that when the baffle 42 is removed, the rectangular slot 41 opens, so that the counterweight bar can enter from the rectangular slot 41, which is used to close the position of the rectangular slot.

[0033] Reference Figure 1 The upper and lower straight beams 4 have mounting holes at the middle upwards, and the straight beams 4 on both sides are connected to abutment members 6. In this embodiment, the mounting holes on the straight beams 4 on both sides are used to install the abutment members 6. The straight beams are also made of channel steel, and the openings of the straight beams 4 on both sides are arranged opposite each other.

[0034] Reference Figure 2 There are two channel steels 3, with their openings facing upwards and downwards respectively. The mating surfaces of the two channel steels 3 are detachably connected by bolts. The end of the straight beam 4 is located at the edge of the channel steel 3's groove and is detachably connected to the channel steel 3 by bolts. In this embodiment, the connection between the upper counterweight assembly 1 and the lower counterweight assembly 2 is achieved by using two channel steels 3, solving the problem in the prior art where a longer counterweight frame needs to be replaced when the weight reaches the limit of the counterweight frame. One or more sets of straight beams 4 can be added to the middle of the two channel steels 3, thus making the length of the straight beams 4 two or more sets. When a set of straight beams 4 is added, the upper and lower ends of the added straight beam 4 are connected to the channel steel 3, and the newly added channel steel 3 is connected to the original channel steel by bolts.

[0035] Reference Figure 5The abutment 6 is U-shaped and located inside the straight beam 4. Both sides of the abutment 6 are connected to the mounting holes in the straight beam 4 via bolts. A connecting hole is formed in the middle plane of the abutment 6, and an adjusting screw 61 is connected inside the connecting hole. Nuts 62 are threaded onto the upper and lower sides of the adjusting screw 61. In this embodiment, the abutment 6 is a U-shaped block, preferably with one side lower than the other. Two bolts are connected to one side, and one bolt is connected to the other. This U-shaped design makes it easier for workers to change the position of the abutment 6 and facilitates its installation. During use, the position of the abutment 6 can be changed, allowing for the use of different numbers of abutment blocks. When connecting the counterweight to the straight beam, the abutment 6 can be removed and slid directly onto the counterweight. By tightening the nuts 62, the position of the adjusting screw 61 relative to the abutment 6 can be changed, thereby further tightening the counterweight.

[0036] Reference Figure 1 Both the upper counterweight assembly 1 and the lower counterweight assembly 2 are connected to a bottom shell 7, which is snapped into the slot of the straight beam 4. In this embodiment, the bottom shell 7 is designed so that the bottommost counterweight bar is located inside the bottom shell 7, avoiding direct contact between the lower side of the counterweight bar and the bolt that serves as the connection, thereby increasing the contact area between the counterweight bar and the bottom shell 7.

[0037] Reference Figure 2 A traction member 12 is connected to the middle of the upper beam 11. In this embodiment, the traction member 12 is used to connect a steel rope to achieve traction of the device.

[0038] Reference Figure 3 A buffer seat 22 is connected to the middle of the lower beam 21. In this embodiment, the buffer seat 22 is provided to first withstand the impact force when the device comes into contact with the ground, thereby playing a buffering role.

[0039] Reference Figure 3 The upper part of the upper counterweight assembly 1 and the lower part of the lower counterweight assembly 2 are connected by a limiting slider 8. In this embodiment, the limiting slider 8 is provided to allow the counterweight assembly to move in the vertical direction without shifting during vertical movement.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
