Description

Technical Field

[0001] This utility model relates to the field of counterweight suspension, and in particular to a counterweight suspension device. Background Technology

[0002] A counterweight suspension device is a device used to fix and suspend counterweights. It is mainly used in various scenarios that require balance or stability of the center of gravity. In the construction or engineering field, it uses a simple mechanical structure to fix counterweights of different sizes and prevent them from falling.

[0003] While existing suspension devices can position the counterweight using positioning rods to prevent it from falling off the device, they still have other problems during use. For example, the positioning effect is poor, and the through holes inside the counterweight are often larger than the positioning rods. Therefore, when the device is shaken, it is easy for the counterweight to shift and collide, which not only generates noise but also easily causes wear on the counterweight. Moreover, it does not have side protection function and cannot protect the counterweight from the side. If the counterweight collides with the device when it tilts, it is easy to damage the counterweight, resulting in poor safety. In order to solve the above problems, we propose a counterweight suspension device. Utility Model Content

[0004] The purpose of this invention is to provide a counterweight suspension device that solves the problems of poor positioning effect and lack of side protection function of existing suspension devices.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a counterweight suspension device, including a base, a positioning rod symmetrically welded to the top of the base, a housing bolted to the top of the base, a threaded rod rotatably connected inside the housing, a threaded plate threadedly connected to the surface of the threaded rod, pressure plates bolted to both sides of the threaded plate, two fixed frames symmetrically bolted to the bottom of the base, a movable block provided inside the fixed frame, a fixing spring bolted between one side of the movable block and the fixed frame through a spring fixing plate, a connecting rod installed on the other side of the movable block, and a baffle installed at the other end of the connecting rod.

[0006] The above technical solution achieves good positioning effect, improves the stability of the counterweight after placement, facilitates quick retrieval of the counterweight, and provides side protection to reduce damage to the counterweight during collisions, thus extending the service life of the counterweight and making it highly practical.

[0007] The present invention is further configured such that: the other end of the threaded rod extends to the outside of the base and is equipped with a throttle handle.

[0008] By adopting the above technical solution and by setting the throttle, it is easy for personnel to rotate the threaded rod.

[0009] The present invention is further configured such that a damper is installed between one side of the moving block and the fixed frame.

[0010] By adopting the above technical solution, the damper can be used to suppress the jumping of the fixed spring, consume the kinetic energy stored in the fixed spring, and improve stability.

[0011] The present invention is further configured such that: a guide rod is welded to the front of the movable block, a sliding groove is provided on the front of the fixed frame, and the other end of the guide rod extends to the outside of the sliding groove.

[0012] By adopting the above technical solution, the guide rod and sliding groove can guide the moving block and prevent it from tilting when moving inward.

[0013] The present invention is further configured such that a rubber pad is bolted to the other side of the baffle.

[0014] By adopting the above technical solution and installing rubber pads, damage to the baffle and foreign objects caused by impact can be reduced.

[0015] The present invention is further configured such that the base, positioning rod, housing and threaded rod are all made of stainless steel.

[0016] Using the above technical solution, the base, positioning rod, housing, and threaded rod have the characteristics of high strength, low density, and excellent corrosion resistance.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. This utility model first fixes the housing to the designated position with screws. After the housing is fixed, the counterweight is picked up, passed through the positioning rod, and placed on the base. After all the counterweights are placed, the handle is held by hand to drive the threaded rod to rotate. When the threaded rod rotates, it will drive the threaded plate and the pressure plate to move downward. When the pressure plate moves downward, it will pass through the positioning rod and press on the counterweight. This can achieve a good positioning effect, improve the stability of the counterweight after placement, and facilitate quick removal of the counterweight.

[0019] 2. When the side is impacted, the rubber pad will cause the baffle to move inward due to the impact. When the baffle moves inward, it will cause the moving block to move together through the fixing of the connecting rod. When the moving block moves, it will press the fixing spring and damper. When the fixing spring and damper contract, they will absorb and offset the impact force, which can provide side protection function, reduce the damage to the counterweight during the collision, extend the service life of the counterweight, and has high practicality.
