Description
Technical Field
[0001] This utility model relates to the field of elevator counterweight transportation technology, and in particular to a modular counterweight handling accessory and an elevator counterweight. Background Technology
[0002] In elevator systems, counterweights are key components that ensure operational balance and safety. These counterweights are typically made of concrete, which involves first creating the counterweight shell, then pouring concrete into it and allowing it to solidify. Handle grooves or holes are pre-drilled on opposite sides to accommodate manual handling during installation, maintenance, and replacement.
[0003] The existing handle installation method usually involves pre-installing plastic handles on the side wall of the counterweight shell before pouring concrete. However, the operator must adopt a specific gripping posture with palms facing each other and towards the side of the counterweight. Only by having the palms facing inward can the handle be effectively gripped. This posture is particularly inconvenient in confined spaces such as narrow elevator shafts, pits, or machine rooms. It is difficult for the operator to flexibly adjust their position according to the space on site, which can easily lead to excessive twisting of the wrist and uneven stress on the waist. Long-term operation can easily cause strain injuries. It is also very inconvenient for transporting the counterweight during the production and manufacturing process.
[0004] If an attempt is made to improve handling by changing the structure of the counterweight, the counterweight needs to be redesigned and molded, which significantly increases manufacturing costs. Even the elevator counterweight installation equipment may need to be adjusted accordingly, resulting in excessive costs. Utility Model Content

[0032] In elevator systems, counterweights are key components that ensure operational balance and safety. These counterweights are typically made of concrete, which involves first creating the counterweight shell, then pouring concrete into it and allowing it to solidify. Handle grooves or holes are pre-drilled on opposite sides to accommodate manual handling during installation, maintenance, and replacement.
[0033] The existing handle installation method usually involves pre-installing plastic handles on the side wall of the counterweight shell before pouring concrete. However, the operator must adopt a specific gripping posture with palms facing each other and towards the side of the counterweight. Only by having the palms facing inward can the handle be effectively gripped. This posture is particularly inconvenient in confined spaces such as narrow elevator shafts, pits, or machine rooms. It is difficult for the operator to flexibly adjust their position according to the space on site, which can easily lead to excessive twisting of the wrist and uneven stress on the waist. Long-term operation can easily cause strain injuries. It is also very inconvenient for transporting the counterweight during the production and manufacturing process.
[0034] If an attempt is made to improve handling by changing the structure of the counterweight, the counterweight needs to be redesigned and molded, which significantly increases manufacturing costs. Even the elevator counterweight installation equipment may need to be adjusted accordingly, resulting in excessive costs.
[0035] This utility model proposes a modular counterweight handling accessory.
[0036] Please see Figures 1 to 4 In one embodiment of this utility model, the modular counterweight handling accessory includes:
[0037] The handle 1 has a recessed mounting surface with a lifting limiting groove 11 and a plug groove 12. The plug groove 12 is located at one end of the lifting limiting groove 11 along the length direction, and the lifting limiting groove 11 and the plug groove 12 are connected.
[0038] The connector 2 includes a handling handle 21 and a connector 22, wherein the handling handle 21 and the connector 22 are fixedly connected.
[0039] The insertion slot 12 is used to insert the insertion part 22. The lifting limiting slot 11 has a sliding groove 13 on the side opposite to the mounting surface. One side of the sliding groove 13 is connected to the side wall of the insertion slot 12. The insertion part 22 is inserted into the sliding groove 13 through the insertion slot 12 and moves along the sliding groove 13. The insertion part 22 is partially blocked by the side wall of the lifting limiting slot 11 to prevent the insertion part 22 from disengaging from the handle 1.
[0040] It is understandable that when the connector 2 is inserted, the handling handle 21 is located outside the counterweight block, which facilitates handling.
[0041] The technical solution of this utility model adopts the detachable connection of the handle 1 and the plug 2. The plug 22 is inserted into the plug groove 12 and slides into the slide groove 13. The side wall of the lifting limit groove 11 prevents it from falling off. The operator can naturally hold the external carrying handle 21 for carrying. After carrying, it is only necessary to slide it back along the slide groove 13 to the plug groove 12 to complete the separation. Without changing the counterweight mold, the handle 1 is installed on the side wall of the counterweight. The operator only needs to hold the plug 2 to carry the counterweight. Even counterweights of different sizes can be carried by the same plug 2.
[0042] In some embodiments, the length direction of the lifting limiting groove 11 is consistent with the length direction of the installed counterweight. The connector 2 needs to move within the slide groove 13 along the length direction of the counterweight to achieve locking and removal. Due to the gravity of the counterweight during transportation, the connector 2 will tilt to a certain extent. However, since the tilt direction of the connector 2 is perpendicular to the length direction of the limiting groove, it will not cause the connector 2 to slide, thus ensuring stability during transportation.
[0043] In other embodiments, the length direction of the lifting limiting groove 11 is perpendicular to the length direction of the installed counterweight, and the insertion groove 12 is located at the lower part of the lifting limiting groove 11. It can be understood that during transportation, due to the gravity of the counterweight, the insertion piece 2 will move upward and tilt relative to the counterweight. However, since the insertion groove 12 is located at the lower part, the insertion piece 2 will not detach during transportation, ensuring safety during transportation.
[0044] It is understandable that the lifting limiting groove 11 can also be directly grasped by hand. Even without the connector 2, the operator can directly grasp the lifting limiting groove 11 to complete the transport, avoiding the scenario where it is impossible to transport without the connector 2. In addition, the sliding groove 13 provided on the side of the lifting limiting groove 11 away from the mounting surface provides bending space for the fingers and facilitates manual transport.
[0045] like Figure 2 As shown, the plug-in part 22 includes a connecting rod 221 and a plug-in block 222, and the two ends of the connecting rod 221 are respectively fixedly connected to the handling handle 21 and the plug-in block 222;
[0046] The plug-in block 222 is slidably connected to the slide groove 13, the plug-in block 222 slides along the slide groove 13, and the connecting rod 221 slides within the lifting limiting groove 11.
[0047] It is understood that when the plug block 222 slides in the slide groove 13, the connecting rod 221 moves synchronously along the lifting limit groove 11, and the torque is directly transmitted to the force point of the handle 1 when the operator lifts through the connecting rod 221.
[0048] like Figure 2 and Figure 3 As shown, the handle 1 also includes a locking block 14, which is located on opposite sides of the lifting limiting groove 11. The bottom wall of the lifting limiting groove 11 is connected to the sliding groove 13. The opening of the sliding groove 13 is blocked by the locking block 14. The insertion block 222 is located in the sliding groove 13, and both ends of the insertion block 222 are blocked by the locking block 14.
[0049] Understandably, the locking blocks 14 located on both sides of the lifting limiting groove 11 form a physical barrier, reducing the area covered by the groove opening of the slide 13 to a width smaller than that of the insertion block 222, so that both ends of the insertion block 222 inserted into the slide 13 are always blocked by the locking blocks 14, thus eliminating the risk of the insertion block 222 slipping off along the opening direction of the slide 13 due to vibration or tilting during the transport of the counterweight.
[0050] Furthermore, both ends of the plug-in block 222 are blocked by the locking block 14, ensuring that the plug-in block 222 moves smoothly in the slide groove 13, avoiding jamming or accidental dislodgement due to force deviation, and improving the reliability of locking.
[0051] like Figure 2 As shown, the opening direction of the slide groove 13 is the same as the opening direction of the insertion groove 12, and the bottom wall of the slide groove 13 is flush with the bottom wall of the insertion groove 12.
[0052] It is understood that the bottom wall of the slide 13 is flush with the bottom wall of the insertion slot 12, so that after the insertion block 222 is inserted from the insertion slot 12, it can slide into the slide 13 without moving or adjusting along the opening direction of the insertion slot 12, which facilitates docking and improves handling efficiency.
[0053] Optionally, the slide groove 13 is clearance-fitted with the plug block 222.
[0054] It is understood that the slide 13 and the plug block 222 are fitted with a clearance to ensure that the plug block 222 is not prone to tilting or shaking when moving in the slide 13, thus ensuring stability during transportation.
[0055] It should be noted that in some embodiments, the plug-in block 222 is a cuboid, and the depth of the groove 13 matches the thickness of the plug-in block 222, ensuring that the plug-in block 222 abuts against the surface of the groove 13 during transportation, thus avoiding stress concentration.
[0056] like Figure 3 and Figure 4 As shown, the sliding groove 13 has a locking groove 15 at one end away from the insertion groove 12. The insertion groove 12 is connected to the locking groove 15. The depth of the locking groove 15 is greater than the depth of the sliding groove 13, so that the insertion block 222 can be tilted.
[0057] The insertion block 222 is tilted, and the side wall of the insertion block 222 near the slide groove 13 abuts against the side wall of the locking groove 15 to prevent the insertion block 222 from sliding into the slide groove 13.
[0058] It should be noted that, since the depth of the locking groove 15 is greater than the depth of the sliding groove 13, and the depth of the sliding groove 13 matches the thickness of the plug-in block 222, the plug-in block 222 will tilt at a certain angle relative to the bottom surface of the locking groove 15 during transportation, so that the plug-in block 222 tilts relative to the bottom surface of the sliding groove 13 and cannot slide into the sliding groove 13, thereby preventing the plug-in part 2 from disengaging from the handle 1 during transportation and ensuring the safety of transportation.
[0059] like Figure 3 As shown, the slot 15 is provided with a correction protrusion 16, the correction protrusion 16 is provided with a correction surface 161, and the correction surface 161 is flush with the bottom surface of the slide groove 13.
[0060] Understandably, after the transportation is completed, the operator can tilt the connector 2 to make the connector block 222 and the correction surface 161 of the correction protrusion 16 fit together to complete the correction, and then slide the connector block 222 into the slide groove 13 along the correction surface 161 to complete the unlocking.
[0061] In some embodiments, the correction protrusion 16 is located at the lower part of the locking groove 15. It is understood that due to the weight of the counterweight, the upper part of the plug-in block 222 will tilt towards the center of the counterweight during transportation, and the lower part will be away from the counterweight. During transportation, the correction protrusion 16 will not abut against the plug-in block 222, ensuring that the plug-in block 222 is tilted relative to the bottom surface of the slide groove 13 and cannot slide into the slide groove 13.
[0062] Optionally, the handle 1 further includes an abutment plate 17, which is used to abut against the outer wall of the counterweight.
[0063] It is understood that an installation opening is usually made on the side wall of the housing 3 of the counterweight to embed the handle 1. When the handle 1 is installed, the abutment plate 17 abuts against the outer side wall of the counterweight, that is, against the outer side wall of the housing 3, restricting the handle 1 from continuing to move toward the center of the counterweight, which facilitates the installation of the handle 1.
[0064] It should be noted that the abutment plate 17 and the mounting surface are located on the same side as the handle 1.
[0065] Optionally, the handle 1 is provided with a buckle 18 on its periphery, the buckle 18 being used to abut against the inner sidewall of the counterweight.
[0066] It can be understood that when the handle 1 is inserted into the side wall opening of the counterweight, the buckle 18 will be compressed and undergo elastic deformation. After the handle 1 is installed in place, the buckle 18 will return to its original position and abut against the inner side wall of the counterweight, that is, against the inner side wall of the housing 3, thus restricting the handle 1 from moving away from the counterweight.
[0067] It is understood that the abutment plate 17 and the buckle 18 restrict the movement of the handle 1 in two opposite directions, ensuring that the handle 1 is not easily dislodged from the side wall of the counterweight after it is installed.
[0068] It should be noted that the part of the handle 1 located inside the counterweight block has a gap between it and the adjacent side wall of the counterweight block. When the grout is poured, the grout will seep into these gaps and surround the handle 1, preventing the handle 1 from detaching from the counterweight block.
[0069] This utility model also proposes an elevator counterweight block, which includes the modular counterweight block handling accessories. The specific structure of the modular counterweight block handling accessories is as described in the above embodiments. Since this elevator counterweight block adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0070] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
