Description

Technical Field

[0001] This utility model relates to the field of hook counterweight technology, specifically a new type of wear-resistant hook counterweight for tower cranes. Background Technology

[0002] The new type of wear-resistant hook counterweight for tower cranes is a specially designed accessory to increase the weight of the tower crane hook and reduce wear. It is mainly used to increase the weight and stability of the tower crane to ensure the safety of the tower crane when working at height.

[0003] To ensure the parallelism of the lower end of the wire rope used for lifting, a new type of tower crane hook counterweight has been developed (see patent number: 201320576461.4). The counterweight is characterized by a steel plate with a triangular front shape and rounded corners (the apex and two base corners of the triangle). The rounded corners include a first and a second hole. The first hole is located at the top of the steel plate, and the second hole is located at the bottom, symmetrically arranged below the first hole. This invention increases the weight of the tower crane hook through the counterweight. The first hole prevents the main wire rope from slipping out of its groove; the second hole keeps the upper ends of the wire ropes separate, reducing wear caused by tangling; and maintains the spacing between the wire ropes, preventing rope tangling. The second hole is symmetrically arranged.

[0004] However, the existing large hook weights are easily affected by inertia during use, causing them to sway the fishing target and making it difficult to ensure that the hook is snagged smoothly. This results in poor performance and reduced usage. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that existing large hook counterweights are easily affected by inertia during use, causing them to sway the fishing targets and making it impossible to ensure that the targets are snagged smoothly, thus resulting in poor performance and reduced utilization. The present invention provides a new type of wear-resistant large hook counterweight for tower cranes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel wear-resistant hook counterweight for tower cranes, comprising:

[0007] Support components are used to support the large hook of the entire new tower crane;

[0008] A snap-fit ​​component is located on one side of the support component and is movably connected to the support component;

[0009] The counterweight is located on the support assembly and is detachably connected to the support assembly via a snap-fit ​​assembly;

[0010] The support assembly includes a first limiting plate, a support column is provided at the middle position of the bottom of the first limiting plate, a second limiting plate is provided at the bottom of the support column, a hook is provided at the bottom of the second limiting plate, and an elastic lever is provided on the top side inside the hook. The locking assembly includes a support rod, a rotating rod is provided at the top of one end of the support rod, a locking block is provided on the side of the support rod near the counterweight, a pin is provided at the bottom of one end of the support rod, a groove is provided at one end of each counterweight, and a slot is provided on one side of each counterweight.

[0011] As a further improvement of this utility model: a fixing block is provided on one side of the first limiting plate, and the top of one end of the support rod is rotatably connected to the first limiting plate through the cooperation of the rotating rod and the fixing block.

[0012] As a further embodiment of this utility model: a connecting block is provided on one side of the second limiting plate, and a mating hole matching the pin is provided at one end of the connecting block. The support rod is detachably connected to the second limiting plate through the mating hole, the pin and the connecting block.

[0013] As a further improvement of this utility model: the counterweight is located on the outside of the support column, and the counterweight is detachably connected to the support column through a groove.

[0014] As a further embodiment of this utility model: the slot matches the locking block, and the counterweight is connected to the support rod by the cooperation of the slot and the locking block.

[0015] As a further improvement of this utility model, the counterweight is detachably connected to the second limiting plate via a support rod, a snap-fit ​​block, and a snap-fit ​​groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] With the support components, snap-fit ​​components, and counterweights included, during use, the pin is removed from the support rod, and then the support rod is rotated around the rotating rod as a base point, causing the support rod to shift outwards carrying the snap-fit ​​block. The counterweight is then placed on the outside of the support column, adjacent to the end faces of the first and second limiting plates, with the groove on the counterweight positioned on the outside of the support column. After placing an appropriate number of counterweights, the rod is rotated again until the snap-fit ​​block on the side of the support rod aligns with the slot on the counterweight and engages. The pin is then used to fix the support rod to the second limiting plate, thus ensuring more stable installation of the counterweight. The support rod and snap-fit ​​block provide limiting support for the counterweight, preventing wobbling during use, improving wear resistance, enhancing performance, and increasing utilization.

After placing an appropriate number of counterweights 3, the support rod 202 is rotated with the rotating rod 202 as the base point. The movement continues until the snap-fit ​​block 203 on the side of the support rod 201 aligns with and snaps into the slot 302 on the counterweight 3. Then, the pin 204 is used to fix the support rod 201 to the second limiting plate 103, thereby making the installation of the counterweight 3 more stable. The support rod 201 and the snap-fit ​​block 203 provide limiting support for the counterweight 3, thus preventing the hook 104 from shaking during use, thereby improving its wear resistance, improving its performance, and increasing its utilization rate.
